Description

[Detailed Description of the Invention] The present invention relates to a structure for preventing slippage of shoji such as sliding sashes or single-sliding sashes.

Conventionally, in this type of retaining structure, a retaining member is loosely fitted to 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 it had been moved and the shoji had been hung up, it had been returned to its original position. In this case, the lower end of the retaining 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 retaining member, thereby preventing the shoji from falling off. However, with such a conventional anti-slip structure, when the upper window frame is warped upward and the lower window frame is warped downward, or when either frame is extremely warped, the upper edge of the shoji and the window top The gap between the frame and the lower end of the vertical wall was larger than the hanging allowance between the lower end of the shoji and the rail of the window bottom frame, and in this case, if the shoji were lifted by some kind of impact, it would come off and fall off.

The purpose of the present invention is to solve the above-mentioned problems of the prior art, and therefore to provide a shoji slip-stopping structure that can prevent the shoji from coming off even if the upper and/or lower frames of the window warp. It is to be.

In order to achieve the above object, the shoji slip-stopping structure according to the present invention is such that the lower frame is provided with a flange portion protruding from the vertical wall on the base at a nearly right angle, and the lower stile of the shoji is provided with a flange portion that protrudes from the vertical wall on the base of the shoji. A stopper having contact parts that wrap at appropriate intervals is installed on the lower side of the flange part so as to be adjustable up and down, and the vertical sliding part of the stopper is held so as to guide its vertical movement. , and the stopper is characterized in that the position of the stopper is adjusted by engaging a screw provided in the horizontal portion of the lower stile with an internal screw formed in the horizontal portion of the stopper.

Next, description will be given with reference to the drawings. Figures 1 and 2 show a conventional retaining structure, in which 1 is a lower frame, 2 is an upper frame, and 3 is a lower frame.
is a shoji. In the conventional structure, the vertical wall 2 of the upper frame 2
Since the anti-slip member 4 was attached to the shoji 1, when the lower frame 1 and the upper frame 2 warp as shown in FIG. The gap 5 becomes larger than the hanging allowance 6 between the lower end 32 of the shoji and the rail 11 of the lower frame 1, resulting in the above-mentioned drawback. In addition, in the figure, 7 is a door roller.

In the shoji sliding prevention structure according to the present invention, the third
As shown in Fig. 4, the base 1 of the lower frame 1
2 is provided with a vertical wall 13 parallel to the rail 11, and the upper part of the vertical wall 13 is provided with a flange portion 14 projecting therefrom at a substantially right angle. Accordingly, a square-shaped groove 15 is defined in the lower frame 1 by the rail 11, the vertical wall 13, and the flange portion 14. On the other hand, a stopper 34 is provided on the lower stile 33 of the shoji 3, and as shown in FIG.
4 includes a vertical slide portion 35, a contact portion 36 projecting laterally from the lower end thereof, a flat plate portion 37 projecting laterally from the upper end of the slide portion 35 to the opposite side, and a hanging portion 38 extending downward from the edge thereof. It is completed. This stopper 34 can be adjusted up and down, so that a screw 8 provided on a prospective surface 39 of the lower stile 33 engages with an internal screw thread formed on a flat plate portion 37 of the stopper 34. The abutting portion 36 is provided at an appropriate interval 1 below the flange portion 14 of the lower frame.
6 and the distance 16 thereof is smaller than the hanging distance 6 of the door roller 7. Figure 4 1
7 is a wrap distance of the abutment portion 36 with respect to the flange portion 14.

In a preferred form, a guide member 40 for holding the stopper 34 in a vertically movable state is provided on the facing surface 41 of the lower stile. As shown in FIG. 6, this guide member 40 consists of a flat plate part 42 and flange parts 43, 44 on both sides of the flat plate part 42. It is fixed to the attached surface 41. When the guide member 40 is attached, the slide portion 35 of the stopper 34 is loosely sandwiched between the flat plate portion 42 of the guide member and the facing surface 41 of the lower stile. Usually, one shoji 3 is provided with two stoppers 34.

Therefore, since the anti-slip structure of the present invention is configured as described above, even if the upper and lower frames warp and the lower stile of the shoji tries to lift, the contact portion 3 of the stopper 34
6 hits the flange part 14 of the lower frame 1, the door roller 7 does not come off the rail 11, and the shoji is prevented from coming off the lower frame and falling off. To remove the shoji 3, turn the screw 8 to lower the stopper 34 until it touches the top surface of the flat plate part 42 of the guide member 40, as shown in FIG.
The flange portion 14 of the lower frame 1 and the contact portion 36 of the stopper
The distance 16 between the shoji and the shoji is larger than the hanging allowance 6 of the door roller, and the shoji can be removed.

In the above embodiment, the adjustment movement of the stopper 34 in the vertical direction is guided by the guide member 40, but it is also possible to restrain the stopper 34 in vertical movement by other methods. For example, the 8th
As shown in the figure, a pair of vertical slots 45 may be provided in the flat plate part 42 of the stopper, and a pin 46 may be passed through these slots.
A retaining ring 47 is attached. In this case, screw 8
By this operation, the stopper 34 can be lowered until the upper edge of the slot 45 touches the pin 46, and at that position, the distance 16 is configured to be larger than the hanging distance 6 of the door roller.

Therefore, according to the present invention, even if the upper frame and/or the lower frame warp and the gap at the upper end of the shoji becomes larger than the gap at the lower end of the shoji, the flange part of the lower frame and the abutting part of the lower stile of the shoji do not engage. Depending on the situation, it is possible to prevent the shoji from falling off.
