Description

An application for application of Article 30, Paragraph 2 of the Patent Act has been submitted. The application was posted on the Sports Authority Rakuten Market website on March 20th, 2023.

The present invention relates to uppers and shoes.

In the past, shoes have been proposed that have an opening that can be widened when putting on and taking off shoes whose upper covers the wearer's foot up to near the ankle, making it easier to put on and take off the shoes (see, for example, Patent Document 1 below). Patent Document 1 discloses an example of this type of shoe, in which a slit is formed at a position around the periphery of the opening and a zipper is provided to open and close the slit. In the above shoe, the slit opens and the opening widens when the shoe is put on or taken off by opening the zipper.

JP 2022-112308 A

However, with these shoes, the wearer must bend down and manually open the zipper before putting on or taking off the shoes, making it difficult for wearers who have difficulty bending down to put on or take off the shoes.

In addition, in the above shoes, the slit extends diagonally backward and downward from the inside edge of the opening. Although this type of slit opens when putting on or taking off the shoes, and the opening widens somewhat, it is not possible to widen the opening enough to make putting on or taking off the shoes easier.

The present invention was made in consideration of these points, and its purpose is to provide shoes that can be easily put on and taken off without using hands.

In order to achieve the above object, the first aspect of the present invention is a shoe upper having an upper body that covers the wearer's foot and has an opening that opens around the wearer's ankle, and at least one of the inner and outer upper parts of the upper body is formed with a dividing section consisting of a cut or notch that extends from the periphery of the opening in a forward downward direction, and the front end of the dividing section is located forward of the instep section and rearward of the waist section of the upper body.

Here, the instep portion of the upper body refers to the portion of the upper body that corresponds to the measurement line of the wearer's instep girth. In this application, as shown in FIG. 1, when the rear end and front end of the sole support surface are respectively positioned at 0% and 100% in the fore-aft direction of the shoe, the instep portion is defined as the portion where the upper body intersects with a predetermined inclined plane Si that passes through a position of 35% in the fore-aft direction of the sole support surface of the sole. The inclination angle α of the predetermined inclined plane Si with respect to the horizontal plane is a predetermined angle between 50 degrees and 70 degrees, and is set for each shoe.

The waist portion of the upper body refers to the portion of the upper body that corresponds to the measurement line of the wearer's waist girth. In this application, as shown in FIG. 1, when the rear end and front end of the sole support surface are respectively positioned at 0% and 100% in the front-to-rear direction of the shoe, the waist portion is defined as the portion where the upper body intersects with a predetermined inclined plane Sw that passes through a 50% position in the front-to-rear direction of the sole support surface of the sole. The inclination angle β of the predetermined inclined plane Sw with respect to the horizontal plane is a predetermined angle between 50 degrees and 70 degrees, and is set for each shoe.

The inclination angles α and β are set so that the instep portion and the waist portion do not intersect in the upper body.

In the first form of shoe upper, a dividing section consisting of a cut or notch extending from the periphery of the opening in a downward direction toward the front is formed on at least one of the inner and outer upper parts of the upper body, and the dividing section divides a part of the upper body into an upper side part above the dividing section and a heel side part below the dividing section. With this configuration, when putting on or taking off the shoe, the instep side part is raised by the wearer's instep, which is inclined downward toward the front, so that the inclination angle with respect to the ground surface is larger than when the shoe is worn or not worn, and the dividing section width is widened, and the opening is widened in the foot length direction. In addition, since the periphery of the opening is also divided into front and rear by the dividing section and is not annular, the opening does not narrow in the foot width direction when it widens in the foot length direction, and the circumference of the opening is lengthened and the opening is widened. This prevents the wearer's foot from getting caught when putting on or taking off the shoes, and reduces frictional resistance, making it easier for the wearer to insert and remove their foot into and from the shoe. In other words, putting on and taking off the shoes becomes easier.

In the first form of shoe upper, the dividing section extends from the periphery of the opening in a downward forward direction to a position forward of the instep section of the upper body. Therefore, compared to when the dividing section does not reach the instep section, the length in the foot length direction of the instep side section, which is raised by the instep of the wearer's foot when putting on or taking off the shoe, is longer, and the opening is wider in the foot length direction. Furthermore, when putting on or taking off the shoe, the instep side section is raised and the width of the dividing section is widened, so that the periphery of the instep section of the upper body is longer, making it easier to put on or take off the shoe.

On the other hand, in the first form of shoe upper, the dividing portion does not extend to the waist portion of the upper body, and the waist portion of the upper body is not divided by the dividing portion. If the dividing portion were extended to the waist portion of the upper body, the instep portion would stand up when walking, and there is a risk that the shoe may slip off or come off when walking. However, with the above configuration, the waist portion of the upper body can firmly hold the area around the arch of the wearer's foot, so the shoe will not slip off or come off while walking, and even if a dividing portion is formed in the upper body, the holding ability is not impaired.

As a result, the first type of shoe upper can provide shoes that can be easily put on and taken off without using your hands, without compromising holding power.

The second embodiment is the first embodiment, characterized in that a heel counter is provided on the heel portion of the upper body, and the heel portion of the upper body has an inclined portion that is inclined upward toward the rear above the heel counter so that the upper end is located at the rearmost part of the heel portion, and a reinforcing member is provided on the inclined portion.

In the second form of shoe upper, an inclined portion is provided above the heel counter of the heel portion of the upper body, inclined upward at the rear so that its upper end is located at the rearmost part of the heel portion. With this configuration, when putting on the shoes, the wearer's foot, which is inclined downward at the front, is smoothly guided into the shoe by the inclined portion, and when taking off the shoes, the wearer's foot, which is inclined downward at the front, is smoothly guided out of the shoe without getting caught in the heel portion. Therefore, according to the second form, it is possible to provide shoes that are easier to put on and take off.

In addition, in the second form of shoe upper, a heel counter is provided on the heel portion of the upper body, and a reinforcing member is provided on the inclined portion above the heel counter. By increasing the strength of the heel portion of the upper body in this way, the instep portion is more easily deformed than the heel portion when putting on or taking off the shoe, and the upper body assumes a shape that is suited to the forward downward shape of the wearer's foot when putting on or taking off the shoe. Therefore, according to the second form, the shoe can be put on or taken off more smoothly.

The third embodiment is characterized in that, in the first or second embodiment, a restoring mechanism is further provided that applies a restoring force to the periphery of the divided portion of the upper body so that the width of the divided portion returns to its original width when the width of the divided portion increases.

The shoe upper of the third embodiment further includes a restoring mechanism that applies a restoring force to the periphery of the divided portion of the upper body to return the width of the divided portion to its original size when the width of the divided portion widens. Therefore, even if the instep side portion is raised by the instep of the wearer's foot when putting on or taking off the shoe, and the width of the divided portion widens, the restoring mechanism quickly tries to return the width of the divided portion to its original size after putting on or taking off the shoe (when the shoe is worn or not worn), and the circumference of the opening becomes shorter than the thickest heel girth portion of the wearer's foot (the portion corresponding to the measurement line of the heel girth of the foot). Therefore, the fit is improved when the shoe is worn, and the shoe can quickly return to its original shape when not worn.

The fourth embodiment is the third embodiment, wherein the restoring mechanism has a first elastic member that extends in a first direction from a lower end attached below the dividing portion of the upper body around the dividing portion and straddles the dividing portion, and has an upper end attached above the dividing portion around the dividing portion of the upper body, and the first elastic member is configured to stretch when the width of the dividing portion widens, thereby exerting a contraction force on the dividing portion of the upper body around the dividing portion.

The shoe upper of the fourth embodiment has a restoring mechanism, which has a lower end and an upper end attached below and above the dividing portion around the dividing portion of the upper body, and has a first elastic member extending in a first direction in a front-upward direction across the dividing portion, and the first elastic member is configured to stretch when the width of the dividing portion widens and apply a contraction force to the periphery of the dividing portion of the upper body. Therefore, when the instep side portion is raised by the instep of the wearer's foot and the width of the dividing portion widens when the shoe is put on or taken off, the first elastic member stretches, and the contraction force (restoration force) of the stretched first elastic member acts on the periphery of the dividing portion of the upper body. Therefore, according to the shoe upper of the fourth embodiment, after the shoe is put on or taken off (when worn and when not worn), the instep side portion raised by the instep of the wearer's foot can be quickly returned to its original position or its vicinity (at least to a position where the circumference of the opening is shorter than the heel girth portion of the wearer's foot).

The fifth embodiment is the fourth embodiment, wherein the restoring mechanism further includes a second elastic member that extends from a lower end attached below the dividing portion of the upper body around the dividing portion in a second direction that is upward toward the front and across the dividing portion, and whose upper end is attached above the dividing portion around the dividing portion of the upper body, and the second elastic member is configured to stretch when the width of the dividing portion widens, thereby exerting a contraction force on the dividing portion of the upper body, and the second direction is upward relative to the first direction.

In the fifth embodiment of the shoe upper, the restoring mechanism further includes, in addition to the first elastic member, a second elastic member whose lower and upper ends are attached below and above the dividing portion around the dividing portion of the upper body, and which extends in a second direction in a front-upward direction across the dividing portion, and the second elastic member is configured to stretch when the width of the dividing portion widens, thereby exerting a contraction force around the dividing portion of the upper body. Therefore, when the instep side portion is raised by the instep of the wearer's foot and the width of the dividing portion widens when the shoe is put on or taken off, the first and second elastic members stretch, and contraction forces (restoring forces) in two different directions (first and second directions) act around the dividing portion of the upper body due to the stretched first and second elastic members. Therefore, with the fifth form of shoe upper, after putting on or taking off the shoe (whether it is worn or not), the instep side portion that is raised by the instep of the wearer's foot can be returned more quickly and accurately to its original position or close to it (at least to a position where the circumference of the opening is shorter than the heel girth portion of the wearer's foot).

In addition, in the fifth form of shoe upper, in addition to the first elastic member, a second elastic member is further provided that extends in a second direction upward from the extension direction (first direction) of the first elastic member and exerts a contraction force in the second direction around the divided portion of the upper body, making it easier for the shoe to fit the wearer's foot after wearing, improving the fit.

The sixth embodiment is the fifth embodiment, wherein the restoring mechanism further includes a support member having at least a rod-shaped portion attached to the periphery of the divided portion of the upper body and above the divided portion so as to protrude from the divided portion, and the first elastic member and the second elastic member are configured as a single elastic member that is hooked onto the rod-shaped portion of the support member and folded back at the rod-shaped portion, with both ends fixed at positions offset in front and behind the lower portion.

In the sixth embodiment of the shoe upper, the first elastic member and the second elastic member are made of a single elastic member that is hooked onto and folded back on a rod-shaped portion of a support member that is attached to the upper periphery of the divided portion of the upper body so as to protrude from the divided portion. This allows the restoration mechanism to be provided more compactly than when the first elastic member and the second elastic member are separately attached to the periphery of the divided portion of the upper body.

The seventh embodiment is the third embodiment, in which the dividing portion is a wide V-shaped or U-shaped cutout on the opening side, and the restoring mechanism is attached to the boundary between the dividing portion and the upper body, and has a border portion that borders two sides of the dividing portion, and a connecting portion made of an elastic material that connects the two sides of the border portion so that an elastic restoring force acts on the border portion to return it to its original angle when the angle between the two sides of the border portion increases.

In the seventh form of shoe upper, the dividing portion is configured as a wide V-shaped or U-shaped cutout on the opening side, and the restoring mechanism is configured to have a edging portion that borders two sides of the V-shaped or U-shaped dividing portion attached to the boundary with the dividing portion of the upper body, and a connecting portion made of an elastic material that connects the two sides of the edging portion so that an elastic restoring force (rotational force) that returns the angle between the two sides of the edging portion to its original angle acts on the edging portion when the angle between the two sides of the edging portion increases. Therefore, when the instep side portion is raised by the instep of the wearer's foot when putting on or taking off the shoe, the angle between the two sides of the edging portion increases, and an elastic restoring force that returns the angle between the two sides to its original angle acts on the edging portion by the connecting portion. Therefore, with the seventh form of shoe upper, after putting on or taking off the shoe (whether it is worn or not), the instep side portion that is raised by the instep of the wearer's foot can be quickly returned to its original position or close to it (at least to a position where the circumference of the opening is shorter than the heel girth portion of the wearer's foot).

The eighth embodiment is a shoe that includes a sole having a contact surface that contacts the road surface and an upper that is fixed to the top of the sole and covers the wearer's foot, and the upper is characterized in that it is a shoe upper according to the first embodiment.

According to the eighth embodiment, by providing the shoe upper according to the first embodiment, it is possible to provide shoes that can be easily put on and taken off without using the hands, without compromising holding power.

As explained above, the present invention provides shoes that can be easily put on and taken off without using your hands.

The following describes in detail the embodiments of the present invention with reference to the drawings. The following embodiments are essentially preferred examples and are not intended to limit the scope of the present invention, its applications, or its uses.

First Embodiment of the Invention
1 to 3 show a shoe 1 according to a first embodiment of the present invention. The shoe 1 is applicable to sports shoes for various sports such as running, various ball games, and badminton, sneakers for everyday use, rehabilitation shoes, etc. In the following, the left shoe shown in Figs. 1 to 3 will be described, and a description of the left shoe configured symmetrically to the left shoe will be omitted.

In the following description, the terms "upper" (top side) and "lower" (bottom side) refer to the vertical positional relationship of the shoe 1 (the heightwise positional relationship perpendicular to the surface on which the shoe 1 is placed when placed on a flat surface). The terms "forward" (front side) and "backward" (rear side) refer to the positional relationship of the shoe 1 in the lengthwise direction of the foot. The terms "medial side" and "lateral side" refer to the positional relationship of the shoe 1 in the widthwise direction of the foot.

-Shoe composition-
The shoe 1 includes a sole 10 and an upper (vamp) 20 disposed above the sole 10.

<Sole>
1 to 3, the sole 10 includes an outsole 11 and a midsole 12. The sole 10 is provided on the lowest side of the shoe 1, and has a ground contact surface 10g that comes into contact with a road surface G.

The outsole 11 is provided in a range extending from the front end to the rear end of the sole 10. The outsole 11 is made of a hard elastic material that is harder than the midsole 12. Specifically, suitable materials for the outsole 11 include, for example, thermoplastic resins such as ethylene-vinyl acetate copolymer (EVA), thermosetting resins such as polyurethane (PU), or rubber materials such as butadiene rubber and chloroprene rubber. In this embodiment 1, the outsole 11 is divided into multiple parts. The lower surfaces of the multiple parts that make up the outsole 11 form the ground contact surface 10g that comes into contact with the road surface G when walking or running.

The midsole 12 is provided over the entire range of the sole 10 from the front end to the rear end, and from the medial end to the lateral end in the foot width direction. The upper surface of the midsole 12 is curved to fit the sole of the shoe wearer's foot, and serves as a sole support surface S that supports the sole of the shoe wearer's foot via an insole (not shown).

The midsole 12 is formed from a soft elastic material that is less hard than the outsole 11. Specifically, suitable materials for the midsole 12 include, for example, thermoplastic synthetic resins such as ethylene-vinyl acetate copolymer (EVA) and foams thereof, thermosetting resins such as polyurethane (PU) and foams thereof, and rubber materials such as butadiene rubber and chloroprene rubber and foams thereof. The midsole 12 is laminated on the upper side of the outsole 11 by being fixed to the outsole 11 with an adhesive or the like.

In this embodiment 1, the outsole 11 and midsole 12 constitute a sole 10 having a contact surface 10g that comes into contact with the road surface.

<upper>
The upper 20 includes an upper body 21 that covers the wearer's foot, a heel cover 22, and a reinforcing core material 23.

The upper body 21 is provided in a range from the inner to outer instep side in the range from the front end to the rear end in the front-rear direction of the upper 20, and covers the wearer's foot as a whole. The material of the upper body 21 is not particularly limited, but it can be made of a material having elasticity. Specifically, the upper body 21 can be made of, for example, knitted fabric, woven fabric, nonwoven fabric, mesh material, synthetic leather, artificial leather, natural leather, etc. In this embodiment 1, the upper body 21 is made of multiple sheets of fabric in a bag shape so that cushioning material, a heel counter 24 and a reinforcing member 25 described later can be provided inside. The upper body 21 has an opening O that opens around the wearer's ankle.

In the following description, as shown in FIG. 3, the part on the medial side of the median plane M (the vertical plane passing through the center of the shoe 1 in the foot width direction) of the upper body 21 is referred to as the medial part 21i of the upper body 21, and the part on the lateral side of the median plane M is referred to as the lateral part 21o of the upper body 21.

In this embodiment 1, the upper body 21 is formed so that the height of the rear end is relatively high. Specifically, the rear end of the upper body 21 is formed so that the upper end covers the wearer's ankle. The upper body 21 is also configured to have an inclined portion 21R that is inclined upward toward the rear, above a heel counter 24 (described later) provided in the heel portion. The inclined portion 21R is inclined upward toward the rear, and is provided so that the upper end protrudes backward so that it is located at the rearmost part of the heel portion of the upper body 21. By providing such an inclined portion 21R on the upper body 21, the wearer's foot is smoothly guided by the inclined portion 21R from the outside to the inside of the upper body 21 or from the inside to the outside when putting on or taking off the shoe 1.

Note that although Figures 1 to 3 show the upper body 21 without shoelaces, the upper body 21 of the upper 20 according to the present invention may have a notch in the center in the foot width direction, and the inner upper portion 21i and the outer upper portion 21o may be fastened together by shoelaces above the tongue portion.

The heel cover 22 covers the heel of the upper body 21 from the inner side to the rear end to the outer side. In this embodiment 1, the heel cover 22 is made of synthetic leather, but the material of the heel cover 22 may be any material that has the rigidity to reinforce the heel of the upper body 21. The heel cover 22 is formed in a downward-sloping shape, with each portion covering the heel of the outer and inner parts 21o and 21i of the upper body 21 becoming lower in height as it moves forward.

The reinforcing core material 23 is formed of a strip-shaped member extending in the front-rear direction along the median plane M in the midfoot region in the middle of the front-rear direction of the upper body 21, and is sewn to the upper body 21. In this embodiment 1, the reinforcing core material 23 is formed of a fabric with higher rigidity than the upper body 21, but the material of the reinforcing core material 23 may be any material that has a strength sufficient to prevent the instep part 31 of the upper body 21 (described later) from being rolled inward when the wearer puts on the shoe 1.

In this embodiment 1, the rear foot portion of the upper body 21 is reinforced and is less likely to deform. Specifically, a heel counter 24 is provided at the heel portion of the upper body 21, and a reinforcing member 25 is provided at the inclined portion 21R above the heel counter 24 of the upper body 21. In this embodiment 1, the heel counter 24 is provided inside the heel portion of the upper body 21, and the reinforcing member 25 is provided inside the inclined portion 21R.

The heel counter 24 can be made of, for example, thermoplastic resins such as thermoplastic polyurethane (TPU), polyamide elastomer (PAE), ABS resin, ethylene-vinyl acetate copolymer (EVA), etc., thermosetting resins such as epoxy resin and unsaturated polyester resin, thermoplastic rubber (TPR), or natural or synthetic leather.

The heel counter 24 is formed in a curved shape that fits along the heel of the wearer's foot, from the inner side to the rear end to the outer side in the heel portion of the upper body 21. In this embodiment 1, the heel counter 24 is formed in the heel portion of each of the outer and inner parts 21o and 21i of the upper body 21 in a shape that corresponds to the heel cover 22, that is, in a forward-sloping shape that becomes lower in height as it approaches the front.

The reinforcing member 25, like the heel counter 24, can be made of, for example, thermoplastic resins such as thermoplastic polyurethane (TPU), polyamide elastomer (PAE), ABS resin, ethylene-vinyl acetate copolymer (EVA), etc., thermosetting resins such as epoxy resin and unsaturated polyester resin, thermoplastic rubber (TPR), or natural or synthetic leather.

The reinforcing member 25 is formed in a curved shape that fits the wearer's ankle, from the medial side to the lateral side through the rear end in the inclined portion 21R of the upper body 21. In this embodiment 1, the reinforcing member 25 is formed in a shape that corresponds to the inclined portion 21R of the upper body 21, i.e., in a rear-rising shape.

By providing the heel counter 24 and reinforcing member 25 as described above, the rear foot portion of the upper body 21 is reinforced, making it difficult for the rear foot portion of the upper body 21 to deform when putting on or taking off the shoe 1. Although not shown in the drawings in this embodiment 1, a cushioning material is provided inside the heel portion of the upper body 21, on the inside of the heel counter 24 and reinforcing member 25.

[Divided part]
In the upper 20 according to the present invention, a dividing section 30 is formed in at least one of the inner upper section 21i and the outer upper section 21o of the upper body 21, dividing a part of the inner upper section 21i and the outer upper section 21o into an upper side section 31 and a heel side section 32. As shown in Figures 1 to 3, in this embodiment 1, the dividing section 30 is formed in both the inner upper section 21i and the outer upper section 21o of the upper body 21.

The dividing portion 30 extends in a predetermined forward downward direction X from the periphery of the opening O in each of the inner instep portion 21i and the outer instep portion 21o of the upper body 21. The predetermined forward downward direction X is a direction that forms a predetermined angle θ of 30 degrees or more and 50 degrees or less with the horizontal plane, and in this embodiment 1, the angle θ is set to 40 degrees.

The dividing section 30 is configured as a U-shaped cutout that narrows toward the tip. The dividing section 30 is formed so that the front end is located forward of the instep section of the upper body 21 and rearward of the waist section.

Here, the instep portion of the upper body 21 refers to the portion of the upper body 21 that corresponds to the measurement line of the wearer's instep girth. In this application, as shown in FIG. 1, when the rear end and front end of the sole support surface S are respectively positioned at 0% and 100% in the front-rear direction of the shoe 1, the instep portion is defined as the portion where the upper body 21 intersects with a predetermined inclined surface Si that passes through a position of 35% in the front-rear direction of the sole support surface S of the sole 10. The inclination angle α of the predetermined inclined surface Si with respect to the horizontal plane is a predetermined angle of 50 degrees or more and 70 degrees or less, and in this embodiment 1, it is 60 degrees.

The waist portion of the upper body 21 refers to the portion of the upper body 21 that corresponds to the measurement line of the wearer's waist girth. In this application, as shown in FIG. 1, when the rear end and front end of the sole support surface S are respectively positioned at 0% and 100% in the front-rear direction of the shoe 1, the waist portion is defined as the portion where the upper body 21 intersects with a predetermined inclined plane Sw that passes through a 50% position in the front-rear direction of the sole support surface S of the sole 10. The inclination angle β of the predetermined inclined plane Sw with respect to the horizontal plane is a predetermined angle between 50 degrees and 70 degrees, and is 60 degrees in this embodiment 1.

The inclination angles α and β are set so that the instep portion and the waist portion do not intersect in the upper body 21. Specifically, the inclination angles α and β are set so that the top end of the instep portion (the portion on the median plane M) is located further rearward than the top end of the waist portion (the portion on the median plane M).

[Restoration mechanism]
The upper 20 according to the present invention further includes a restoring mechanism 40 that applies a restoring force to the periphery of the separated portion 30 of the upper body 21 so that the width of the separated portion 30 returns to its original width when the width of the separated portion 30 formed in the upper body 21 increases. In the present embodiment 1, the restoring mechanism 40 has a first elastic member 41 and a second elastic member 42.

The first elastic member 41 and the second elastic member 42 are both band-shaped members made of elastic material. The lower ends of both the first elastic member 41 and the second elastic member 42 are attached around the dividing portion 30 of the upper body 21 below the dividing portion 30, and extend in a front-upward direction across the dividing portion 30. The first elastic member 41 extends in a front-upward first direction Y1, and the second elastic member 42 extends in a front-upward second direction Y2 that is higher than the first direction Y1. The upper ends of both the first elastic member 41 and the second elastic member 42 are attached around the dividing portion 30 of the upper body 21 above the dividing portion 30.

The first elastic member 41 and the second elastic member 42 are both configured to stretch when the width of the dividing portion 30 widens, and to exert a contraction force (the first elastic member 41 exerts a contraction force in the first direction Y1, and the second elastic member 42 exerts a contraction force in the second direction Y2) on the periphery of the dividing portion 30 of the upper body 21. In this embodiment 1, the contraction forces of the first elastic member 41 and the second elastic member 42 become the restoring force.

In this embodiment 1, the first elastic member 41 and the second elastic member 42 are composed of an elastic member 43, which is a single band-shaped member made of an elastic material. The restoration mechanism 40 further has an annular member (support member) 44 attached to the periphery of the dividing portion 30 of the upper body 21 and protruding above the dividing portion 30. The annular member 44 is attached to the tip of a band-shaped support member 45, the base end of which is attached above the dividing portion 30 of the upper body 21. The elastic member 43 is hooked onto the rod-shaped portion of the annular member 44 and folded back at the rod-shaped portion, with the portion extending in the first direction Y1 forming the first elastic member 41 and the portion extending in the second direction Y2 forming the second elastic member 42.

-Upper performance-
(Easy to put on and take off)
When putting on or taking off the shoes 1, the wearer's foot is tilted downward at the front, and the thickest heel girth part of the foot (the part corresponding to the measurement line of the heel girth of the foot) passes through the opening O. Therefore, if the circumference of the opening O is shorter than the heel girth part of the wearer's foot, the heel girth part of the wearer's foot gets caught near the opening O when putting on or taking off the shoes 1, and frictional resistance increases, making it difficult to insert the foot into the shoes 1 and also difficult to remove the foot from the shoes 1.

In this embodiment 1, a dividing section 30 is formed in the inner instep section 21i and the outer instep section 21o of the upper body 21, and the dividing section 30 divides a part (rear half) of the inner instep section 21i and the outer instep section 21o into an instep side section 31 above the dividing section 30 and a heel side section 32 below the dividing section 30. With this configuration, when putting on and taking off the shoes 1, the instep side section 31 is raised by the instep of the wearer's foot, which is inclined downward toward the front, so that the inclination angle with respect to the ground surface 10g is larger than when the shoes are worn and when they are not worn, and the width of the dividing section 30 is widened, and the opening O is widened in the foot length direction. At this time, the peripheral part of the opening O is also divided into front and rear by the dividing section 30 and is not annular, so that when the opening O is widened in the foot length direction, the opening O does not narrow in the foot width direction, and the circumference of the opening O is long and the opening O is widened. This prevents the wearer's foot from getting caught in the heel girth when putting on or taking off the shoe 1, and reduces frictional resistance, making it easier for the wearer to insert the foot into the shoe 1 and also easier for the wearer to remove the foot from the shoe 1. In other words, putting on or taking off the shoe 1 becomes easier.

In addition, in this embodiment 1, the dividing portion 30 extends from the periphery of the opening O in the downward forward direction X to a position forward of the instep portion of the upper body 21. Therefore, compared to a case where the dividing portion 30 does not reach the instep portion, the length in the foot length direction of the instep side portion 31 that is raised by the instep of the wearer's foot when putting on or taking off the shoe is longer, and the opening O is wider in the foot length direction. Also, when putting on or taking off the shoe 1, the instep side portion 31 is raised and the width of the dividing portion 30 is widened, so that the periphery of the instep portion of the upper body 21 is longer, making it easier to put on and take off the shoe 1.

Furthermore, in this embodiment 1, the upper body 21 is configured to have an inclined portion 21R that is inclined upward at the rear, above the heel counter 24, so that its upper end is located at the rearmost part of the heel. With this configuration, when putting on the shoes 1, the wearer's foot, which is inclined downward at the front, is smoothly guided into the shoes 1 by the inclined portion 21R, and when taking off the shoes 1, the wearer's foot, which is inclined downward at the front, is smoothly guided out of the shoes 1 by the inclined portion 21R without getting caught in the heel. In other words, putting on and taking off the shoes 1 becomes smooth.

(holding ability, fit)
If the dividing portion 30 extends too far in the front downward direction X and reaches the waist portion, the upper portion 31 will stand up even when walking, and there is a risk that the shoe 1 will slip off or come off when walking.

In this embodiment 1, the dividing portion 30 does not extend to the waist portion of the upper body 21, and the waist portion of the upper body 21 is not divided by the dividing portion 30. Therefore, the waist portion of the upper body 21 can firmly hold the area around the arch of the wearer's foot, so that the shoe 1 does not slip or come off while walking, and the formation of the dividing portion 30 in the upper body 21 does not impair the holding ability.

In addition, in this embodiment 1, the upper 20 further includes a restoring mechanism 40 that exerts a restoring force around the separated portion 30 of the upper body 21 so that the width of the separated portion 30 returns to its original width when the width of the separated portion 30 widens. Therefore, even if the instep side portion 31 is raised by the instep of the wearer's foot and the width of the separated portion 30 widens when the shoe 1 is put on or taken off, the restoring mechanism 40 quickly attempts to return the width of the separated portion 30 to its original width after the shoe 1 is put on or taken off (when worn or not worn). Specifically, in this embodiment 1, when the instep side portion 31 is raised by the instep of the wearer's foot and the width of the separated portion 30 widens when the shoe 1 is put on or taken off, the elastic member 43 (the first elastic member 41 and the second elastic member 42) stretches, and the contraction force (the contraction force in the first direction Y1 and the contraction force in the second direction Y2) of the stretched elastic member 43 acts around the separated portion 30 of the upper body 21. Therefore, in this embodiment 1, the instep portion 31, which is raised by the instep of the wearer when putting on or taking off the shoes 1, quickly returns to its original position or close to it (at least a position where the circumference of the opening O is shorter than the heel girth portion of the wearer's foot) after putting on or taking off the shoes 1 (when the shoes are worn and when they are not worn). This improves the fit of the shoes 1 when they are worn, and allows them to quickly return to their original shape when they are not worn.

In addition, as described above, if the upper 20 is provided with the dividing portion 30, when the upper 20 is lifted by the wearer's foot after wearing the shoe 1, for example, when walking, the dividing portion 30 widens in width and the instep portion 31 rises, which may cause the shoe 1 to slip or come off when walking. However, in this embodiment 1, since the restoration mechanism 40 is provided, even if the dividing portion 30 tries to widen in width when the upper 20 is lifted by the wearer's foot, such as when walking, the contraction force of the elastic member 43 (the first elastic member 41 and the second elastic member 42) acts to prevent the dividing portion 30 from widening in width and the instep portion 31 from rising. Therefore, the upper body 21 can firmly hold the wearer's foot, and the shoe 1 does not slip or come off when walking. In particular, by providing the second elastic member 42 that exerts a contractile force in the second direction Y2 around the dividing portion 30 of the upper body 21, the shoe 1 becomes easier to fit to the wearer's foot after wearing, improving the fit.

--Effects of the First Embodiment--
As described above, in the upper 20 of the present embodiment 1, the inner instep portion 21i and the outer instep portion 21o of the upper body 21 are formed with a dividing portion 30 consisting of a notch extending in the forward downward direction X from the periphery of the opening O, and the dividing portion 30 divides a part (rear half) of the upper body 21 into an instep portion 31 above the dividing portion 30 and a heel portion 32 below the dividing portion 30. With this configuration, when putting on or taking off the shoe 1, the instep portion 31 is raised by the wearer's instep, which is inclined downward toward the front, so that the inclination angle with respect to the ground surface 10g is larger than when the shoe is worn or not worn, and the width of the dividing portion 30 is increased, and the opening O is expanded in the foot length direction. In addition, the periphery of the opening O is also divided into front and rear by the dividing portion and is not annular, so that when the opening O widens in the foot length direction, the opening O does not narrow in the foot width direction, and the circumference of the opening O becomes longer and the opening O becomes wider. This prevents the wearer's foot from getting caught when putting on or taking off the shoes 1, and reduces frictional resistance, making it easier for the wearer to insert and remove the foot into and from the shoes 1. In other words, putting on and taking off the shoes 1 becomes easier.

In the upper 20 of this embodiment 1, the dividing portion 30 extends from the periphery of the opening O in the downward forward direction X to a position forward of the instep portion of the upper body 21. Therefore, compared to when the dividing portion 30 does not reach the instep portion, the length in the foot length direction of the instep side portion 31 that is raised by the instep of the wearer's foot when putting on or taking off the shoe is longer, and the opening O is wider in the foot length direction. In addition, when putting on or taking off the shoe 1, the instep side portion 31 is raised and the width of the dividing portion 30 is widened, so that the periphery of the instep portion of the upper body 21 is longer, making it easier to put on or take off the shoe 1.

On the other hand, in the upper 20 of this embodiment 1, the dividing portion 30 does not extend to the waist portion of the upper body 21, and the waist portion of the upper body 21 is not divided by the dividing portion 30. If the dividing portion 30 were extended to the waist portion of the upper body 21, the instep portion 31 would stand up when walking, and there is a risk that the shoe 1 may slip off or come off when walking. However, with the above configuration, the waist portion of the upper body 21 can firmly hold the area around the arch of the wearer's foot, so that the shoe 1 will not slip off or come off while walking, and even if the dividing portion 30 is formed in the upper body 21, the holding ability is not impaired.

As described above, according to this embodiment 1, it is possible to provide shoes 1 that can be easily put on and taken off without using hands, without compromising holding power.

In addition, in the upper 20 of this embodiment 1, an inclined portion 21R is provided above the heel counter 24 in the heel portion of the upper body 21, inclined upward at the rear so that its upper end is located at the rearmost part of the heel portion. With this configuration, when putting on the shoes 1, the wearer's foot, which is inclined downward at the front, is smoothly guided into the shoes 1 by the inclined portion 21R, and when taking off the shoes 1, the wearer's foot, which is inclined downward at the front, is smoothly guided out of the shoes 1 without getting caught in the heel portion. Therefore, this embodiment 1 can provide a shoe 1 that is easier to put on and take off.

In addition, in the upper 20 of this embodiment 1, a heel counter 24 is provided on the heel portion of the upper body 21, and a reinforcing member 25 is provided on the inclined portion 21R above the heel counter 24. By increasing the strength of the heel portion of the upper body 21 in this way, the instep portion 31 is more easily deformed than the heel side portion 32 when putting on or taking off the shoe 1, and the upper body 21 takes a shape that is suitable for the forward downward shape of the wearer's foot when putting on or taking off the shoe. Therefore, the upper 20 of this embodiment 1 allows the shoe 1 to be put on or taken off more smoothly.

In addition, the upper 20 of this embodiment 1 further includes a restoring mechanism 40 that applies a restoring force around the separated portion 30 of the upper body 21 so that the width of the separated portion 30 returns to its original width when the width of the separated portion 30 widens. Therefore, even if the above-mentioned instep side portion 31 is raised by the instep of the wearer's foot when putting on or taking off the shoe 1, and the width of the separated portion 30 widens, the restoring mechanism 40 quickly tries to return the width of the separated portion 30 to its original width after putting on or taking off the shoe 1 (when worn or not worn).

Specifically, in the upper 20 of the first embodiment, the restoring mechanism 40 has a lower end and an upper end attached below and above the dividing portion 30 of the upper body 21 around the dividing portion 30, and has a first elastic member 41 extending in a first direction Y1 in a forward upward direction across the dividing portion 30, and the first elastic member 41 is configured to stretch when the width of the dividing portion 30 widens, and to apply a contraction force to the periphery of the dividing portion 30 of the upper body 21. With this configuration, when the instep side portion 31 is raised by the instep of the wearer's foot and the width of the dividing portion 30 widens when the shoe 1 is put on or taken off, the first elastic member 41 stretches, and the contraction force (restoration force) of the stretched first elastic member 41 acts on the periphery of the dividing portion 30 of the upper body 21. Therefore, with the upper 20 of this embodiment 1, after putting on or taking off the shoe 1 (when worn or not worn), the instep side portion 31 that is raised by the instep of the wearer's foot can be quickly returned to its original position or close to it (at least to a position where the circumference of the opening O is shorter than the heel girth portion of the wearer's foot).

In the upper 20 of the present embodiment 1, in addition to the first elastic member 41, the restoring mechanism 40 further includes a second elastic member 42 whose lower and upper ends are attached below and above the dividing portion 30 of the upper body 21 around the dividing portion 30, and which extends in the second direction Y2 in a forward upward direction across the dividing portion 30, and the second elastic member 42 is configured to stretch when the width of the dividing portion 30 widens, thereby exerting a contraction force on the periphery of the dividing portion 30 of the upper body 21. According to this configuration, when the instep side portion 31 is raised by the instep of the wearer's foot and the width of the dividing portion 30 widens when the shoe 1 is put on or taken off, the first and second elastic members 41, 42 stretch, and a contraction force (restoring force) in two different directions (first direction Y1 and second direction Y2) acts on the periphery of the dividing portion 30 of the upper body 21 by the stretched first and second elastic members 41, 42. Therefore, with the upper 20 of this embodiment 1, after putting on or taking off the shoe 1 (whether it is worn or not), the instep side portion 31 that is raised by the instep of the wearer's foot can be returned more quickly and accurately to its original position or to a position close to it (at least to a position where the circumference of the opening O is shorter than the heel girth portion of the wearer's foot).

In addition, in the upper 20 of this embodiment 1, in addition to the first elastic member 41, a second elastic member 42 is further provided that extends in a second direction Y2 upward from the extension direction (first direction Y1) of the first elastic member 41 and exerts a contraction force in the second direction Y2 around the dividing portion 30 of the upper body 21, making it easier for the shoe 1 to fit the wearer's foot after wearing, improving the fit.

In the upper 20 of this embodiment 1, the first elastic member 41 and the second elastic member 42 are configured as a single elastic member 43 that is hooked onto and folded back on a rod-shaped portion of an annular member 44 that is attached to the upper periphery of the divided portion 30 of the upper body 21 so as to protrude into the divided portion 30. Therefore, the restoration mechanism 40 can be provided more compactly than when the first elastic member 41 and the second elastic member 42 are separately attached to the periphery of the divided portion 30 of the upper body 21.

Second Embodiment of the Invention
The shoe 1 of the second embodiment is obtained by partially modifying the configuration of the upper 20 of the shoe 1 of the first embodiment. Specifically, in the second embodiment, as shown in Fig. 4, the upper 20 does not include a restoration mechanism 40. Even with this configuration, by forming a separation portion 30 in the upper body 21, it is possible to provide a shoe 1 that can be easily put on and taken off without using hands, as in the first embodiment.

Third Embodiment of the Invention
The shoe 1 of the third embodiment is obtained by partially modifying the configuration of the upper 20 of the shoe 1 of the first embodiment.

Specifically, in the third embodiment, as shown in FIG. 5, the dividing portion 30 is configured by a wide V-shaped cutout on the opening O side. The restoring mechanism 40 is configured to have a edging portion 46 and a connecting portion 47. The other configurations are the same as those of the first embodiment.

The edging portion 46 is attached to the boundary with the dividing portion 30 of the upper body 21, and is composed of two strip-shaped members that edging two sides of the V-shaped dividing portion 30. In this embodiment 3, the edging portion 46 is composed of an elastic material. The elastic material that composes the edging portion 46 may be any material that has a hardness that does not bend when an elastic restoring force from the connecting portion 47 described below acts on it, but for example, a thermoplastic resin such as ethylene-vinyl acetate copolymer (EVA), a thermosetting resin such as polyurethane (PU), or a rubber material such as butadiene rubber or chloroprene rubber is suitable.

The connecting portion 47 is provided between the two sides 46a, 46b of the edging portion 46 and connects the two sides 46a, 46b. In this embodiment 3, the connecting portion 47 is formed in a C-shape, and the two sides 46a, 46b of the edging portion 46 are connected to the two ends of the connecting portion 47. The connecting portion 47 is made of an elastic material so that when the angle between the two sides 46a, 46b of the edging portion 46 increases, an elastic restoring force (rotational force) that returns the angle to the original angle acts on the edging portion 46. In this embodiment 3, the edging portion 46 and the connecting portion 47 are integrally molded from the same elastic material. The elastic material constituting the connecting portion 47 may be any material that generates the above-mentioned elastic restoring force (rotational force), but for example, a thermoplastic resin such as ethylene-vinyl acetate copolymer (EVA), a thermosetting resin such as polyurethane (PU), or a rubber material such as butadiene rubber or chloroprene rubber is suitable.

In the third embodiment, the restoring mechanism 40 is configured as described above, and when the upper part 31 is raised by the instep of the wearer's foot and the width of the divided part 30 is expanded when the shoe 1 is put on or taken off, the angle between the two sides 46a, 46b of the edging part 46 is enlarged, and an elastic restoring force (rotational force) that returns the angle between the two sides 46a, 46b to the original angle acts on the edging part 46 by the connecting part 47. As a result, the upper body 21 is pulled by the edging part 46, and the width of the divided part 30 tries to quickly return to its original width. Therefore, even with the upper 20 of the third embodiment, the upper part 31 raised by the instep of the wearer's foot can be quickly returned to its original position or its vicinity (at least to a position where the circumference of the opening O is shorter than the heel girth part of the wearer's foot) after the shoe 1 is put on or taken off (when worn and when not worn).

Other Embodiments
In the above-mentioned first to third embodiments, the dividing portion 30 is configured by a notch, but the dividing portion 30 may be configured by a cut extending from the periphery of the opening O in the front downward direction X. Even if the dividing portion 30 is configured by a cut, as in the above-mentioned first to third embodiments, the opening O can be widened and the periphery length of the instep portion of the upper body can be lengthened when putting on or taking off the shoe 1, so that the shoe 1 can be easily put on or taken off. In addition, by positioning the tip of the cut (the front end of the dividing portion 30) behind the waist portion of the upper body 21, the holding property is not impaired even if the dividing portion 30 is formed in the upper body 21, as in the first to third embodiments. Therefore, even if the dividing portion 30 is configured by a cut, the shoe 1 can be easily put on or taken off without using hands, without impairing the holding property.

In addition, in the above embodiments 1 to 3, the dividing portion 30 is formed in both the inner instep portion 21i and the outer instep portion 21o of the upper body 21, but it may be provided in only one of them. Even if the dividing portion 30 is formed in only one of the inner instep portion 21i and the outer instep portion 21o of the upper body 21, as in the above embodiments 1 to 3, the opening O can be widened and the perimeter of the instep portion of the upper body can be lengthened when putting on and taking off the shoe 1, making it easier to put on and take off the shoe 1. Note that, when the dividing portion 30 is formed in only one of the inner instep portion 21i and the outer instep portion 21o of the upper body 21, it is preferable to form it in the inner instep portion 21i.

In addition, in the above embodiments 1 to 3, the dividing portion 30 is configured with a U-shaped or V-shaped notch, but the shape of the notch is not limited to a U-shape or a V-shape.

In addition, in the above-mentioned third embodiment, the dividing portion 30 is configured with a V-shaped notch, but the dividing portion 30 may be configured with a U-shaped notch. Furthermore, the two sides of the dividing portion 30 configured with a V-shaped or U-shaped notch and the two sides 46a, 46b of the border portion 46 bordering the two sides of the dividing portion 30 do not necessarily have to be straight, and even if they are curved, the same effect as in the third embodiment can be achieved.

In addition, in the above embodiments 1 to 3, the heel portion of the upper body 21 is configured to have an inclined portion 21R, but the heel portion of the upper body 21 does not have to have an inclined portion 21R.

In addition, in the above embodiments 1 to 3, the heel counter 24 is provided inside the heel portion of the upper body 21, and the reinforcing member 25 is provided inside the inclined portion 21R, but the heel counter 24 may be provided outside the heel portion of the upper body 21, and similarly, the reinforcing member 25 may be provided outside the inclined portion 21R.

In addition, in the above embodiments 1 to 3, the heel counter 24 and the reinforcing member 25 are separate members, but the heel counter 24 and the reinforcing member 25 may be a single member. In that case, the heel counter 24 and the reinforcing member 25 made of a single member may be provided inside the upper body 21 or outside the upper body 21.

In addition, in the above-mentioned first embodiment, the first elastic member 41 and the second elastic member 42 of the restoring mechanism 40 are composed of a single elastic member 43, but they may be composed of separate elastic members and attached separately to the upper body 21. In addition, the restoring mechanism 40 may not have the second elastic member 42.

Furthermore, in the above-mentioned embodiment 1, the first elastic member 41 and the second elastic member 42 of the restoring mechanism 40 are strip-shaped members made of an elastic material, but as long as they are made of an elastic material and extend in the first direction Y1 and the second direction Y2, respectively, they do not have to be strip-shaped members, and may be rod-shaped or string-shaped members.

In addition, in the above-mentioned embodiment 1, the elastic member 43 is hooked onto the rod-shaped portion of the annular member 44 and folded back to be supported by the annular member 44, but the member that folds back and supports the elastic member 43 is not limited to the annular member 44. Any member that has a rod-shaped portion attached to the upper periphery of the dividing portion 30 of the upper body 21 so as to protrude into the dividing portion 30 does not have to be an annular member 44, and may be a simple rod-shaped member.

In addition, in the above-mentioned embodiment 3, the restoration mechanism 40 may further have an opening portion that is formed integrally with the edging portion 46 so as to be continuous with the edging portion 46 and is attached to the opening O of the upper body 21 to border the opening O.

In addition, in the above-mentioned third embodiment, the shape of the connecting portion 47 is not limited to a C-shape, and may be any shape as long as it can apply an elastic restoring force (rotational force) to the edging portion 46 to return it to its original angle when the angle between the two sides 46a, 46b of the edging portion 46 increases.

As described above, the present invention is useful for uppers and shoes.
