Description

  The present invention relates to an improvement of a base plate for attaching board surface parts to a game board surface, and in particular, has a configuration for preventing the edge of the base plate protruding from the game board surface from being worn out by a game ball repeatedly colliding and deteriorating the appearance. The present invention relates to a base plate and panel parts.

In pachinko machines, various board parts such as a game nail, a winning opening, a windmill, a symbol display device, and an illumination device are provided in the game area of the game board in order to diversify the game contents. The board surface component is attached to the board surface by screwing the board to the game board surface while being mounted on the board.
FIG. 7 is a cross-sectional view showing a state in which the base plate 100 is installed on the game board surface 110. The base plate 100 is made of a metal film or the like on the surface of a core material (for example, black) 101 made of a resin plate having a thickness of about 2 mm. A decorative thin film (for example, gold) 102 is coated and formed by a technique such as plating or painting. Further, the outer peripheral edge 103 of the base plate 100 is inclined in a tapered shape (thickness gradually decreases) toward the outer peripheral direction in order to reduce the damage when the game ball hits and the influence on the path of the game ball. Tapered surface. In addition, when the base plate is viewed from the front, changes in shade and color of each surface are caused due to the angle difference between the top surface of the base plate and the tapered surface, so that it is possible to enhance the interest of the player.

By the way, when game balls that are launched from the launching device by about 100 per minute and enter the game area repeatedly collide with the outer periphery of the base plate 100 in the process of flowing down the game area, the upper surface of the base plate and the outer tapered surface The decorative thin film 102 covering the boundary line (obtuse corner portion) 105 is worn and damaged, and a part of the black core material 101 is exposed, which causes the appearance to deteriorate.
Such a problem is likely to occur in a local portion of a base plate that frequently collides in the process of passing a game ball, and is particularly likely to occur in a popular model having a high operation rate.
In order to deal with such problems, the obtuse angled boundary line (ridge line) between the top surface of the base plate and the outer tapered surface is chamfered into a curved surface to eliminate the edge, and when the game ball collides It is also possible to reduce the damage. However, the designer of the base plate provides an obtuse angled ridgeline at the boundary line between the upper surface of the base plate and the tapered surface, so that when the base plate is viewed from the front, the reflection direction of light on each surface is made different. Therefore, since the design effect is recognized in which the apparent shade and color of each surface are recognized differently, there is a tendency to avoid processing the ridge line into an R shape.

Patent Document 1 (Japanese Patent Laid-Open No. 05-168747) discloses that the core material of the base plate is composed of a low-strength synthetic resin having high strength, but a game that collides with a decorative thin film formed on the surface of the core material. No mention is made of a configuration that protects against a ball.
Japanese Patent Laid-Open No. 2005-013589 discloses a configuration for increasing the strength of the base plate, but does not mention any configuration for protecting the decorative thin film from a game ball that collides.
JP 05-168747 A JP 2005-013589 A

As described above, in the base plate attached to the game board surface of the conventional pachinko gaming machine, it is necessary to provide an obtuse corner (ridge line) along the outer peripheral edge, so that a game ball is placed at this corner. When hit, there was a problem that the decorative thin film was worn and damaged, and the undesired core material was exposed and the appearance was deteriorated.

The center accessory 3 shown in FIG. 2 (a) is fixed to the game board surface by screwing and fixing the base board to the game board surface in a state assembled to the base board 20 shown in FIG. 2 (b). .
In the configuration example shown in FIG. 1, the portion A of the base plate 20 on the lower left side of the center accessory 3 is a region where the game balls collide frequently and are most easily worn.
3 (a) and 3 (b) are main part sectional views of a base plate according to an embodiment of the present invention. The base plate 20 includes a base plate base 21 having a substantially flat surface (upper surface) 21a, A taper portion (outer peripheral thin wall portion) 25 that is continuous with at least a part of the periphery of the base plate base portion and inclines downward in the outer peripheral direction, and decorations formed on the surfaces 21a and 25a of the base plate base portion 21 and the taper portion 25, respectively. The decorative thin film 30 (30a, 30b) which consists of a coating film or a coating film, and the transparent protective member 40 are provided. Further, the leading edge of the tapered portion 25 is a rising surface 26 that stands vertically to the game board surface 2a. The base plate base 21 and the taper portion 25 constitute a base plate main body 28.

The base plate 20 has a thickness T of the base plate base 21 in order to minimize the influence on the game ball flowing down on the surface of the game board and to minimize damage when the game ball collides with the edge. The length L of the tapered portion 25 is set to about 3 mm, and the height H of the rising surface 26 is set to about 0.5 mm. The distance from the game board surface 2a to the front glass plate (not shown) is about 20 mm, and the diameter of the game ball is 11 mm. Therefore, there is a gap between the surface of the base plate 20 including the decorative thin film 30 and the glass plate. A game ball passage space of about 17 to 18 mm is secured.
An obtuse (non-curved) corner 27 is formed at the boundary between the base plate base surface 21 a and the tapered portion 25. As described above, the chamfering of the corner portion 27 into a curved surface causes a design disadvantage. In the present invention, while maintaining the design effect due to the presence of the corner portion 27, A measure is provided to eliminate the problem of game balls hitting directly and damaging the decorative thin film.
In other words, the characteristic configuration of the base plate 20 of the present invention is that the transparent protective member is disposed at an appropriate position along the outer peripheral edge of the base plate main body 28 so that the corner portion 27 and the surrounding decorative thin film are played. The structure prevents the ball from hitting directly.

In the base plate 20 according to the embodiment of FIG. 3, the transparent protective member 40 is laminated and integrated (covered integration) on at least the decorative thin film 30b on the tapered portion 25, so that the game ball flowing down the game board surface is square. The contact with the portion 27 is prevented. The transparent protective member 40 may be any material as long as it is a transparent resin excellent in durability, and examples thereof include polycarbonate. Further, the hardness of the transparent protective member 40 is set to be approximately equal to the hardness of the base plate body 28.
The transparent protective member 40 is formed to project from the periphery of the tapered portion 25 so that the lower surface of the transparent protective member 40 covers the surfaces of the tapered portion 25 and the rising portion 26 and the lower surface thereof covers a part of the game board surface 2a.
The range in which the transparent protective member 40 covers the tapered portion 25 may be at least the upper portion of the tapered surface inclined obliquely from the corner portion 27 and does not necessarily reach the lower portion of the tapered portion. The configuration in which the bottom surface of 40 is in contact with the game board surface 2a is more advantageous in securing installation stability.

In the present embodiment, the transparent protective member 40 on the tapered portion 25 forms a transparent tapered surface that is inclined downward in the outer circumferential direction, like the surface of the tapered portion 25. By making the transparent tapered surface of the transparent protective member 40 parallel to the front surface of the tapered portion 25, damage when the game ball hits can be minimized.
Since the decorative thin film 30b that covers the tapered portion 25 and the rising surface 26 is covered with the transparent protective member 40, the appearance when viewed from the front is completely the same as when the transparent protective member 40 is not present. Accordingly, it is possible to maintain the difference in light and shade due to the change in the light reflection direction between the base plate base and the respective surfaces 21a and 25a (30a and 30b) of the taper portion, and the design advantage can be exhibited.
In the embodiment of FIG. 3A, the outer surface shape of the transparent protective member 40 covered on the taper portion 25 is the same shape as the shape of the taper portion 25 and the rising surface 26, so damage caused by the collision of the game ball is prevented. Although it can be reduced, the corners 40A of the transparent protective member 40 are chamfered into a curved surface, or the front surface of the transparent protective member 40 is processed into a curved shape, as shown in FIG. The outer surface may be formed into a curved surface to further reduce damage caused by the game ball.

In the embodiment of FIG. 3, the position P1 of the outermost peripheral edge of the transparent protective member 40 on the game board surface coincides with the original outermost peripheral edge position (original installation position) of the base plate main body 28 on the game board surface 2a. Thus, the influence on the game ball is the same as when the transparent protective member 40 is not present. Since it comprised in this way, the position of the outer periphery P2 of the base-plate main body 28 is retracted | saved to the inner side rather than the original position P1.
Note that the position P2 of the outer peripheral edge of the base plate main body 28 may be set to a position that coincides with the original position P1, and the transparent protective member 40 may be disposed at a position beyond the original position P1. This also applies to all of the following embodiments.
Further, as a method of fixing the transparent protective member 40 to the base plate body 28, both of them are integrally molded in advance, bonded with a transparent adhesive, or the other contact portions are not fixed, and other parts are screwed. For example, a method of tightening together may be considered. Therefore, in this specification, the laminated integration or the covering integration means that the base plate body and the transparent protective member are integrally molded, and a transparent protective member as a separate member is laminated on the base plate body and screwed. It also includes the case of fixing by adhesion or the like.

FIGS. 3C and 3D are longitudinal sectional views showing a specific configuration when the base plate 20 according to the present embodiment is fixed to the game board 2 with screws, and the back surface of the main part (boss portion) of the base plate. It is a side perspective view.
On the back side of the base plate main body 28 constituting the base plate 20, a boss portion 29 is provided so as to be fixed to the game board surface with screws. A semi-cylindrical extension piece 40B that is in close contact with the outer surface of the boss portion 29 extends from the specific portion of the transparent protective member 40 corresponding to the boss portion 29 toward the back side, and the boss portion 29 is provided at the tip of the extension piece 40B. A tip member having a hole 40B that communicates with the screw hole 29 is integrally formed. The base plate 20 is fixed to the game board surface by screwing screws (not shown) into the screw holes 29 and 40B and fastening them together.
In addition, the fixing structure of the base plate shown here can be similarly applied to the following other embodiments.

Next, FIGS. 4A and 4B are cross-sectional views of a main part of a base plate according to another embodiment of the present invention. The base plate 20 has a substantially flat surface (upper surface) 21a. The base 21, the tapered portion (outer peripheral thin wall portion) 25 that is connected to at least a part of the periphery of the base plate base portion 21 and is inclined downward in the outer peripheral direction, and the surfaces 21 a and 25 a of the base plate base portion 21 and the tapered portion 25. A decorative film 30 (30a, 30b) made of a decorative coating or a coating film, a transparent protective member 40 coated and integrated on the decorative thin film 30b on the tapered portion 25, and the transparent protective member 40, respectively. And a transparent protective member 41 that is integrally coated on the decorative thin film 30a on the surface of the base plate base 21.
The base plate base 21 and the taper portion 25 constitute a base plate main body 28.
The characteristic configuration of the base plate 20 according to the present embodiment is that the transparent protective member 40 is formed on the decorative thin film 30b on the tapered portion 25 and the transparent protective member is also provided on the decorative thin film 30a on the base plate base 21. 41 is formed so that both transparent protective members 40 and 41 are connected and integrated. For this reason, the decorative thin film on the corner 27 can be covered with the transparent protective member, and it is possible to prevent the game ball from coming into direct contact with the corner 27 and wearing out the decorative thin film. As the transparent protective members 40 and 41, for example, polycarbonate is used.

The transparent protective member 41 is preferably coated with a uniform thickness on the decorative thin film 30a, and the film thickness is set so that a sufficient space for passing a game ball can be secured between the transparent protective member 41 and the glass plate positioned in front.
Since the decorative thin films 30b and 30a covering the base plate base surface 21a and the taper portion surface 25a are covered with the transparent protective members 41 and 40, the transparent protective member is used to see each surface when viewed from the front. There is no difference from the case where it does not exist. Accordingly, it is possible to maintain a difference in apparent shade and color due to a change in reflected light between the base plate base portion and the respective surfaces 21a and 25a of the taper portion, thereby exhibiting a merit in design.
The thickness T1 of the base plate body 28 when the transparent protective member 41 is laminated on the base plate base 21 increases by the thickness of the transparent protective member 41, but it is sufficient between the glass plate (not shown) disposed in the front. There is no problem because it is possible to secure a passing space for a game ball.
In the embodiment of FIG. 4A, since the outer surface shape of the transparent protective members 40 and 41 is a shape that matches the shape of the tapered portion 25 and the base plate base portion 21, damage due to the collision of the game ball can be reduced. The outer shape of the transparent protective member 40 as shown in FIG. 5B is obtained by chamfering the corner 40A located at the boundary between the two transparent protective members into a curved surface or by forming the transparent protective member 40 into a curved surface. May be formed into a curved surface to further reduce damage caused by game balls.

Next, FIG. 5 is a longitudinal sectional view of a main part of a base plate according to another embodiment of the present invention. The base plate 20 includes a base plate base portion 21 having a substantially flat surface (upper surface) 21a, and a base plate. The taper part 25 which is connected to at least a part of the peripheral edge of the base part 21 and inclines downward in the outer peripheral direction, and the decorative coating or coating formed on each of the surfaces 21a and 25a of the base plate base part 21 and the taper part 25, respectively. A decorative thin film 30 (30a, 30b) made of a film, a transparent protective member 42 disposed on the game board surface 2a along the outer peripheral edge of the taper portion 25, and a base plate body (the base plate base 21 and the taper portion 25) 28 And a thin plate-like transparent protective member 43 interposed between the lower surface of the game board 2 and the game board surface 2a.
The transparent protective member 42 according to the present embodiment does not cover the surface 25a of the tapered portion 25 like the transparent protective member 40 in the above embodiment, but on the outer peripheral edge of the tapered portion 25 (the rising surface 26). It is arranged along the outer peripheral edge of the taper portion with the lower surface in close contact with the game board surface 2a along, and the vertical inner wall surface 42a is raised to prevent the game ball from hitting the corner portion 27 directly. . A thin plate-like transparent protective member 43 extends from the inner peripheral lower portion of the transparent protective member 42 toward the lower surface of the base plate main body 28, and the base plate main body 28 (the taper portion 25 and the base plate is placed on the transparent protective member 43. With the base 21) fixed, the base plate 20 is fixed to the game board surface with screws.
The surface of the transparent protective member 42 may be bent at an obtuse angle as shown in the figure to form a tapered surface, or the entire surface may be chamfered in a curved shape so as to reduce damage at the time of game ball collision. It may be configured.
The base plate main body 28 can avoid a direct hit of the game ball due to the presence of the transparent protective member 42 protruding on the game board surface 2a along the outer peripheral edge thereof. Further, since the base plate main body 28 is not covered or concealed, the player can visually recognize the difference in lightness and shade caused by the difference in angle between the base plate base portion 21 and the taper portion 25. .

Next, FIG. 6 is a longitudinal sectional view of a main part of a base plate according to another embodiment of the present invention, and a stepped step portion (outer peripheral thin portion) provided at least at a part of the outer peripheral edge of the base plate body 28. By protecting 50 with the transparent protective member 44, it is possible to prevent the base plate body from being directly hit by the game ball and damaging the decorative thin film 30.
First, the base plate 20 according to FIG. 6A is provided with a base plate base portion 21 having a substantially flat surface (upper surface) 21a and at least a part of the periphery of the base plate base portion so as to be stepped in the outer peripheral direction. A stepped portion 50 having a reduced thickness, a decorative coating formed on each of the surfaces 21a and 50a of the base plate base 21 and the stepped portion 50, or a decorative thin film 30 (30a, 30c) made of a coating, and transparent And a protection member 44.
The stepped portion (outer peripheral thin portion) 50 includes a middle step portion 51 that is one step lower than the base plate base surface 21a, a rising portion 52 formed along the outer peripheral edge of the middle step portion 51, a base plate base surface 21a, and a middle step portion. And a wall surface 53 located between the two and 51.

The middle stage 51 may be parallel to the game board surface as shown in the figure, or may have a tapered shape in which the wall thickness gradually decreases toward the outer peripheral direction. By making the angle of the middle stage 51 different from the angle of the surface of the base plate base 21, it is possible to express changes in light and shade due to the angle difference between both surfaces.
The wall surface 53 may be a tapered surface as shown, or may be a vertical surface (a surface orthogonal to the game board surface). By using the wall surface 53 as a tapered surface, it is possible to express changes in lightness and shade due to an angle difference from the base plate base surface 21a.
The transparent protective member 44 covers the entire surface of the stepped portion 50 (the middle stepped portion 51, the rising portion 52, and the wall surface 53), so that the decorative thin film 30 is worn away when the game ball directly hits the stepped portion and the corner portion 54. Can be prevented.
As shown in the figure, the surface of the transparent protective member 44 may be bent at an obtuse angle to form a tapered surface, or the entire outer peripheral side may be chamfered in a curved shape to buffer damage from the game ball. You may comprise as follows. This also applies to the following embodiments.

Next, the base plate 20 according to FIG. 6B is characterized in that it includes a transparent protective member 45 in which the transparent protective member 44 is extended to the surface 21a (on the decorative thin film 30a) of the base plate base 21. It is. Since the corner portion 54 of the base plate main body 28 is covered and protected by the transparent protective members 44 and 45, the base plate base surface 21a, the wall surface 53, and the middle step portion that are visually recognized without being directly hit by the game ball. The difference in shade and color from 51 can be effectively used as a design effect.
Next, the transparent protective member equipped on the base plate 20 according to FIG. 6C includes a transparent protective member 46 disposed on the game board surface 2a along at least a part of the outer peripheral edge of the step portion 50, and a base. And a thin plate-like transparent protective member 47 interposed between the lower surface of the board main body (the base plate base 21 and the stepped portion 50) 28 and the game board surface 2a.
The transparent protective member 46 according to the present embodiment is disposed along the outer peripheral edge of the stepped portion with the lower surface in close contact with the game board surface 2a along the outer periphery of the stepped portion 50, and uprights the vertical inner wall surface 46a. This prevents the game ball from hitting the corner portion 54 directly. Further, a plate-like transparent protective member 47 extends from the lower inner peripheral portion of the transparent protective member 46 toward the lower surface of the base plate main body 28, and the base plate main body 28 (the taper portion 25 and the base plate is placed on the transparent protective member 47. With the base 21) fixed, the base plate 20 is fixed to the game board surface with screws.

As described above, according to the present invention, a game ball repeatedly collides with a corner portion (obtuse angled ridgeline) between the base plate base portion and the taper portion, so that the decorative thin film is worn and damaged, and the base material of the base plate becomes It is possible to prevent problems that are exposed and deteriorate the appearance. In the present invention, the transparent protective member is disposed at an appropriate position along the tapered portion as a means for preventing the game ball from directly hitting the corner portion. Since the transparent protective member is made of a transparent material that allows the external appearance of the base plate base and the tapered portion to be visually recognized, the design effect (apparent aesthetic effect) is not lost.
Even when a step portion is provided in place of the taper portion, the transparent protective member exhibits the same corner portion damage prevention effect and design effect.
The transparent protective member is a means for preventing the game ball from directly hitting and contacting the corner between the base plate base and the taper or stepped portion, so that only the front surface of the taper or stepped portion is covered. Even if it comprises, the said effect can be exhibited.

The transparent protective member covered with the tapered portion or the stepped portion may exceed the original installation position of the base plate even when it is formed on the game board surface beyond the outer peripheral edge of the tapered portion or the stepped portion. Configured to not.
By extending the installation range of the transparent protective member to the surface of the base plate base portion instead of only the tapered portion or the stepped portion, the protection of the corner portion of the base plate body can be increased.
Since the taper portion provided on the conventional base plate is appropriately set in size and inclination angle so as to minimize damage when a game ball collides, a transparent protective member that covers this taper portion By similarly setting the outer surface shape, the damage that the transparent protective member receives from the game ball can be reduced.
In order to further reduce the damage received by the transparent protective member from the game ball, it is effective to configure the surface thereof to be curved.
The base plate according to the present invention is a member used when attaching the center accessory and other various board components to the game board surface, and all the board components provided with the base plate according to the present invention are within the technical scope of the present invention.
