Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door, and more particularly, to an improvement of a lower frame and an upper frame constituting a window frame in a sliding window or a single sliding window which is required to have heat insulation performance.

[0002]

2. Description of the Related Art Conventionally, there is known a sliding window having a heat insulating property in which each frame of a window frame is composed of a metal indoor member, a metal outdoor member, and a heat insulating member connecting these members. In the window frame of such a sliding window, since the heat insulating member is interposed between the indoor and outdoor members, even if the outdoor member exposed to the outside is cooled by the outside air, the heat is transmitted to the indoor member on the indoor side. It can be made hard to reach and it is possible to make it difficult to cause dew condensation on the indoor member.

[0003]

However, in the lower frame which constitutes the window frame of the sliding sash, for example, in the lower frame, half of the indoor guide rail, that is, in the state in which each of the inner and outer screens is closed, the inner screen is placed. Since the exposed portion is directly contacted with the outside air to be cooled, this heat is transferred to the other half of the indoor guide rail, that is, the exposed portion inside the room, and dew condensation easily occurs in this portion.

At this time, it is conceivable to cut the longitudinal direction of the room-side guide rail to reduce heat transfer. In this case, however, the shoji door wheel is caught by the cut portion and the shoji screen moves. There is a problem of blocking.

Further, such a problem may similarly occur on the upper frame side of the window frame. That is, in the case where the sliding door is provided with a sliding piece that comes into contact with the indoor guide rail of the upper frame, the sliding piece is caught by the cut portion of the indoor guide rail, and the sliding door cannot be moved well.

An object of the present invention is to provide a sliding door which can prevent dew condensation on the guide rail and can move the shoji satisfactorily.

[0007]

A sliding door according to the present invention is a sliding door in which at least an inner sliding door of indoor and outdoor sliding doors moves along an aluminum guide rail of a lower frame forming a window frame, In the middle of the lower frame guide rail in the longitudinal direction , and
A notch for heat insulation is provided at a position outside the rolling range of the door shovel of the inner shoji in the vicinity of the indoor and outdoor shoji combination section .

According to the present invention, since the guide rail is provided with the cutout portion in the lower frame of the window frame, the guide rail portions on both sides of the cutout portion, that is, the portion directly contacted with the outside air and the indoor side are provided. Between the exposed parts, it becomes difficult for heat to be transferred, and it becomes difficult for dew condensation to occur in the exposed parts on the indoor side. Further, since the cutout portion of the guide rail is provided at a position outside the rolling range of the door shovel of the shoji screen, there is no concern that the door shovel is caught in the cutout portion, and the shoji screen can be moved well.

On the other hand, in the sliding door according to the present invention, at least the inner shoji of the indoor and outdoor shoji is the aluminum of the upper frame constituting the window frame.
A sliding door that moves along the guide rails of the above-mentioned
In the vicinity of the shoji part of the shoji screen , a heat insulating notch is provided at a position outside the sliding range of the sliding piece of the shoji screen.

In the present invention as described above, in the upper frame of the window frame, as in the case of the lower frame described above, dew condensation is less likely to occur at the portion of the guide rail exposed to the inside of the room, and the cutout portion of the guide rail has a sliding door. There is no concern that the sliding piece of 2 will get caught, and the shoji can be moved well.

Further, the sliding door of the present invention is a sliding door in which at least an inner sliding door among indoor and outdoor sliding doors moves along aluminum guide rails of an upper frame and a lower frame which constitute a window frame. In the middle of the longitudinal direction of the guide rails of the frame and the lower frame , and in the vicinity of the interior and exterior sliding doors of the sliding door, at a position outside the rolling range of the door shovel of the inner sliding screen and the sliding range of the sliding piece. It is characterized in that a notch for heat insulation is provided.

That is, according to the present invention, dew condensation is prevented on each of the upper and lower frames of the window frame, and the shoji screen moves well.

Further, the sliding door of the present invention is a sliding door in which at least one of the indoor and outdoor sliding doors moves along the aluminum guide rail of the window frame, and the guide rail of at least the lower frame of the window frame. In the middle of the longitudinal direction of the
An opening for heat insulation is provided in the vicinity of the outer shoji part of the shoji screen so as to leave a continuous upper end of the guide rail .
This opening is closed with a blocking member having a heat insulating property,
The closing member supports the upper end portion .

According to the present invention, by providing an opening in the longitudinal direction of the guide rail, the guide rail portions on both sides of this opening portion are continuous only at the narrowest portion of the upper end portion, so that the opening in the guide rail is formed. Heat transfer between both sides of the part is reduced, and if one part is exposed to the inside of the room, dew condensation on this exposed part is less likely to occur. Further, since the opening is provided while leaving the upper end portion of the guide rail, the door roller of the shoji screen is not caught and the shoji screen can be moved smoothly.

Further, in the above, only the opening is provided.
Not limited to this, the cutout may also be closed by a blocking member having a heat insulating property, and in such a case, intrusion of rainwater or the like from the cutout or the opening is surely prevented.

The guide rails 15 are provided at both longitudinal ends of the swivel portion 26. A door roller 27 that rolls at the upper end portion of the is arranged.

In this embodiment, each frame 1 of the window frame 10 is
The heat insulating members 113 to 133 of 1 to 13 and the heat insulating members 213 to 233 of the frames 21 to 23 of the shoji 20 are formed by a resin injection method. Examples of the heat insulating members include a metal indoor member and an outdoor member. It may be a plate member made of synthetic resin fixed between members by caulking or the like.

Next, the most characteristic configuration of this embodiment will be described below with reference to FIGS. 3, 4 and 5. Figure 3
FIG. 4 is an exploded perspective view showing an enlarged main part of the lower frame 12 in the window frame 10, and FIGS. 4 and 5 are schematic views schematically showing a cross section of the sliding window 1. It shows a case in which it is fully closed and a case in which the internal shoji 20A is fully opened.

Among the guide rails 15 of the lower frame 12, a notch 30 having a predetermined width is provided midway in the longitudinal direction of the indoor guide rail 15A. As shown in FIG. 4 and FIG. 5, the notch portion 30 is provided on both door rollers 27 when the sliding door 20A is slid so as to be completely closed and when it is slid so as to be completely opened. Is provided at a position where it does not straddle, that is, a position outside the rolling range of each door roller 27.

Specifically, the position of the cutout portion 30 is based on the front side of the indoor side of the right vertical frame 13 in FIG.
It is a position away from the vertical frame 13 by a distance A in the finding direction. At this time, the distance between the left and right vertical frames 13 is Ws, the distance from the left vertical frame 13 to the end of the crescent stopper 31 is B, the found size of the inner shob 20A is C, and the inner shob 20A is 20A.
If the distance from the vertical frame 23 on the right side of the to the outer peripheral portion of the door roller 27A is D, the distance A is given by A = Ws−B−C + D. Therefore, if the cutout portion 30 is provided on the left side in the figure with respect to the distance A, the door roller 27A on the right side does not drop into the cutout portion 30 even if the inner sliding door 20A slides in the fully open direction.

In addition, the maximum width dimension of the cutout portion 30 at this time is set to A1, and as shown in FIG.
If the distance from the vertical frame 23 to the outer peripheral portion of the door roller 27B is E on the left side of the frame, and the swollen dimension of the inner shoji 20A into the vertical frame 13 on the right side of the inner shoji 20A is F, the maximum The major dimension A1 is given by A1 = C-A-E-F. Therefore, as long as the cutout portion 30 is provided within the maximum width dimension A1 from the distance A toward the left side, the door roller 27B on the left side is located at the cutout portion 30 even if the inner sliding door 20A slides in the fully closed direction. It does not fall out.

The notch 30 is provided by punching with a press, milling with a machining center, etc., and is closed by a closure member 32 made of resin or wood having an L-shape and having heat insulating properties. Also, reference numeral 3 in FIG.

Further, in the present embodiment, although not shown, in the upper frame 11 which constitutes the window frame 10, the sliding pieces 25 of the inner shoji 20A are attached to the indoor guide rail 14A (FIG. 1). The cutout portion is also provided at a position outside the sliding range, and even if such a cutout portion is provided, the internal shoji 20A
The sliding piece 25 is prevented from being caught in the cutout portion during the sliding. And this notch is also closed by the closing member.

According to this embodiment, the following effects can be obtained. 1) In the lower frame 12 of the window frame 10, since the notch 30 is provided in the indoor guide rail 15A, each shoji 2
When 0 is fully closed, heat is applied to the portion exposed to the indoor side from the right side portion in FIG. 4 with respect to the cutout portion 30, that is, the portion of the indoor guide rail 15A that is directly exposed to the outside air. It is possible to make it difficult to transmit, and it is possible to make it difficult for dew condensation to occur in the portion exposed on the indoor side.

2) Since the notch 30 is provided at a position outside the rolling range of each door roller 27 for the inner shoji 20A, each door wheel 27 is notched by the notch 3 as the inner shovel 20A slides.
There is no need to worry about being caught in 0 or falling off.
Sliding of A can be done without any trouble.

3) According to this embodiment, the upper frame 11 forming the window frame 10 is provided with a notch in the longitudinal direction of the indoor side guide rail 14A. Like the frame 12, the indoor guide rail 14A
It is possible to make it difficult for dew condensation to occur on the part exposed to the indoor side.

4) Since the notch portion on the side of the upper frame 11 is provided at a position outside the sliding range of each sliding piece 25 of the inner shoji 20A, these sliding pieces 25 also have the inner shoji 20A.
There is no concern that the notch will be caught in the sliding of the inner sliding door 20A and the inner sliding door 20A can slide more reliably.

5) Since the cutout portion 30 is closed by the closing member 32, it is possible to reliably prevent rainwater or the like from entering the indoor side through the cutout portion 30. Further, since the closing member 32 has a heat insulating property, there is no fear of impairing the effect of 1) described above. This effect is the same with the closing member provided in the cutout portion of the upper frame.

In the opening 40, a blocking member 41 made of resin or wood having a heat insulating property is arranged. The closing member 41 prevents rainwater and the like from entering by closing the opening 40, and in particular, by being arranged in the opening 40 of the lower frame 12, a continuous portion left above the opening 40. It has the function of supporting 16. Moreover, in the upper frame 11, since the opening is closed, there is no concern that the sliding piece 25 (see FIG. 1) is caught.

The present embodiment has the following effects. 6) The opening 4 is formed in the indoor guide rail 15A of the lower frame 12.
Since 0 is provided, in the guide rail 15A, the heat transfer from the exposed portion to the exposed portion inside the room is the very thin continuous portion 1 left above the opening 40.
It is only done via 6. Therefore, it is possible to make it difficult for heat to be transferred between both parts, and it is possible to make it difficult for dew condensation to occur at the part exposed in the room. That is, according to the second embodiment, although the configuration is different from the first embodiment, the above-mentioned 1)
The effect of 3) can be obtained similarly.

7) Since the upper portion of the indoor guide rail 15A is left above the opening 40 to form the continuous portion 16, the door roller 20A rolls on the continuous portion 16 to cause the inner sliding door 20A to move. Sliding can be performed without any trouble, and although the structure is also different, the effect of 2) described above can be similarly obtained.

8) Since the opening 40 is closed by the blocking member 41 having a heat insulating property, it is possible to prevent infiltration of rainwater and the like, and it is possible to obtain the same effect as 5).

9) Particularly when the closing member 41 is provided in the opening 40 of the lower frame 12, the continuous portion 16 above the opening 40 can be reliably supported, so that the door roller rolls above the opening 40. However, the continuous portion 16 can be prevented from being deformed or damaged, and the durability can be improved.

10) Further, when the closing member 41 is provided especially in the opening of the upper frame 11, the sliding piece 25 of the inner shoji 20A can be prevented from being caught in the opening, and the effect of 4) can be obtained. You can

11) Since the opening 40 need only be provided in the vicinity of the assembled portion of each shoji 20, it is not necessary to strictly control the position and width of the opening as in the first embodiment, and the lower frame 12 can be provided. Easy to make. This effect is the same when the opening is provided in the upper frame 11, and the upper frame 11 can be easily manufactured.
