Description

[Detailed Description of the Invention] The present invention relates to an improvement in a structure for preventing the slipping of a shoji door, preferably used for a single sliding sash.

Conventionally, in this type of retaining structure, a retaining member is loosely fitted into the locking part of the vertical wall of the window upper frame, and when the shoji is removed, the retaining member is moved to an appropriate horizontal position. After hanging the shoji, it was returned to its original position. The lower end of this anti-slip member was kept at the same level as the lower end of the vertical wall of the window upper frame, and even when the shoji was raised, it came into contact with the lower end of the anti-slip member, thereby preventing the shoji from falling off. With such a conventional anti-slip structure, if the top frame of the window warps upward and the bottom frame warps downward, or if one of the frames warps excessively, the upper edge of the shoji and the upper frame are perpendicular to each other. The gap between the lower edge of the wall and the lower edge of the shoji was larger than the hanging allowance between the lower edge of the shoji and the rail of the lower frame, and if the shoji were lifted by some kind of impact, the shoji would come off and fall off.

The present invention overcomes the drawbacks of the prior art mentioned above, and therefore it is an object of the present invention to provide a window sill and/or
Another object of the present invention is to provide a structure for preventing the shoji from coming off even if the lower frame is warped.

The features of the shoji sliding prevention structure of this invention are as follows:
A retaining member with a U-shaped cross section is fitted into the square cross section portion provided on the indoor side of the lower window frame, and a contact portion protruding from the lower stile of a door roller or shoji is inserted into the retaining member. A notch is provided in the lower frame portion and the retaining member to enable insertion or removal of the abutting portion, and the abutting portion contacts the retaining member to prevent the shoji from coming off. It is to be.

Next, description will be given with reference to the drawings. FIGS. 1 to 3 show a conventional anti-slip structure, and in the figures, 1 is the lower frame of the window, 2 is the upper frame, and 3 is the shoji. In the conventional structure, the retaining member 5 was attached to the vertical wall 4 of the upper frame 2, so when the lower frame 1 and the upper frame 2 warp, as shown in FIG. The gap g between the shoji 3 and the lower end of the vertical wall 4 of the upper frame is larger than the hanging allowance 7 between the lower end of the shoji 3 and the rail 6 of the lower frame 1, resulting in the above-mentioned drawback. Note that, as clearly shown in FIG.
It is at the same level as a. In the figure, 8 is a door roller.

Next, an embodiment of the anti-slip structure of the present invention will be described. As shown in FIGS. 4 and 5, the anti-slip structure of the present invention includes a vertical wall 12 parallel to the rail 6 from the indoor edge of the base 11 of the lower frame 1, and a vertical wall 12 above the base 11. wall 12
The lower frame 1 is provided with a flange portion 13 projecting to the outdoor side at right angles to the outside, and further provided with a vertical wall 14 hanging from the end of the flange portion 13, so that the indoor side of the lower frame 1 is provided with a portion having a square cross section. . That is, the portion 1a indicated by the dashed line in FIG.
It is composed of a vertical wall 12, a flange portion 13, and a vertical wall 14, and is open to the outdoor side. As shown in FIG. 5, a retaining member 20 having a generally U-shaped cross section is fitted into the space 15 within the lower frame portion. This anti-slip member 20 includes a flange portion 21 that is substantially parallel to the base 11 of the lower frame, a vertical wall 22 on the indoor side edge of the flange portion 21, and a flange portion 2 that protrudes from the upper end of the vertical wall toward the outdoor side.
3 and a vertical wall 2 rising from the end of the flange portion.
4, defining a U-shaped space 25 inside. Further, in this embodiment, the door roller 8 is provided with a cantilever-shaped abutment part 9 that protrudes toward the indoor side and has a horizontal free end side, as shown in the figure, and the free end side part of the abutment part is prevented from falling off. It is inserted into the space 25 of the member 20 and has an appropriate amount of lap margin 26 with respect to the flange portion 23 of the anti-slip member 20. The gap 27 between the flange portion 23 and the abutment portion 9 is smaller than the hanging distance 7 between the door roller 8 and the lower end of the shoji 3.

Furthermore, as shown in FIGS. 6 and 7, the vertical wall 14 of the lower frame 1 is provided with a notch 16 for inserting and removing the shoji 3, and when the abutment part 9 is provided on the door roller 8, There are a plurality of notches 16, and the spacing a between them is the same as the spacing between the door rollers 8 attached to the lower stile. Further, the width dimension b of the notch 16 is slightly larger than the width dimension of the contact portion 9, and the height c of the notch 16 is
The height dimension is the same as that of the vertical wall 14 of the retaining member 20. Note that the width dimension here means the dimension in the running direction of the shoji, that is, the dimension in the direction parallel to the rails 6. This notch 16 is formed at an optimal position for inserting and removing the shoji 3. Also the 8th
As shown in FIG. 9 and FIG.
The length d of 0 may be any suitable length, but it is preferably slightly larger than the interval a between the notches 16 of the lower frame, so that when placed between the notches 16, the length d is outside the two notches 16. It is designed to generate a slight lapse allowance e. And the vertical wall 2 of the anti-slip member
4 and the flange portion 23 are also formed with a notch 28 having a width dimension b' that is approximately the same as that of the notch 16, and the depth e' of the notch 28 is equal to the lap allowance 26 between the contact portion 9 and the flange portion 23.
The height of the notch 28 is such that the distance 17 (FIG. 13) between the upper end of the notch and the abutting portion 9 is larger than the hanging distance 7 of the door roller.

Further, as shown in FIGS. 10 and 11, in a normal state, the retaining member 20 is
is locked in the wrong position with respect to the notch 16 of the lower frame 1, so that the vertical wall 14 of the lower frame is locked by the screw 10.
The vertical walls 24 of the anti-displacement member 20 are fixed to each other. The anti-slip member 20 has a flange portion 2 thereof.
1 are provided with holes 29 at suitable locations to facilitate movement. Preferably, a stop screw 30 is provided at a predetermined position on the flange portion 13 of the lower frame 1.
is installed, and a retaining member 20 is attached to the screw 30.
12 and 13, the notch 28 of the retaining member 20 is aligned with the notch 16 of the lower frame, as shown in FIGS. 12 and 13.

Therefore, in this anti-slip structure, the anti-slip member 20 is normally fixed to the lower frame 1 with its notch 28 displaced from the notch 16 of the lower frame.
Even if the shoji 3 lifts up when the upper and lower frames are warped, the abutment part 9 will be removed by the flange part 23 of the member that prevents it from coming off.
Alternatively, since it hits the vertical wall 14 of the lower frame 1, the door roller 8 does not come off the rail 6, and therefore the shoji 3 is prevented from falling off. Although it is preferable that the contact portion 9 be provided on the door roller 8 as in the above embodiment, it is not necessarily necessary to provide it on the door roller, and it may be provided on the lower stile of the shoji screen.

When inserting the shoji 3 into the frame or removing it from the frame, the screws 10 are removed, and as shown in FIGS.
0, align the notch 28 with the notch 16 on the lower frame side, and then align the abutting part 9 of the shoji 3 with the notches 16 and 28, allowing the shoji to be lifted up and removed. can. Similarly, the shoji 3 can also be fitted in that position.

Therefore, according to the present invention, even if the gap at the upper end of the shoji becomes larger than the hanging allowance at the lower end of the shoji due to warpage of the upper and lower frames, the abutting portion provided on the lower stile or door roller of the shoji Since the shoji is engaged with a retaining member having a U-shaped cross section installed on the lower frame and abuts against the upper flange, it is possible to prevent the shoji from coming off and falling off.
