Description

[Detailed description of the invention] The present invention relates to the invention of a mechanism for preventing a shoji from falling outside, and which effectively prevents a shoji fitted to a window frame from coming off towards the outside using a simple member. By moving the detachment prevention member, it can be removed only in the direction of the interior of the room.

It is essential to provide windows that can be opened and closed for ventilation and lighting purposes in buildings and structures.
A mechanism that does not require extra space when opening and closing such windows is to run the shoji along rails above and below the window frame. However, in the case of a shoji that is run while being fitted to the upper and lower rails, there is a possibility that the shoji may come off toward the outside.
This means that when opening and closing windows on the upper floors of modern high-rise buildings, the shoji can fall off, and especially when the outer shoji comes off, it is difficult to prevent it from falling internally, making it difficult to prevent it from falling on the street. There is a great danger of falling on the shoji, etc., and damage to the shoji cannot be avoided. Also, the fact that the shoji can be removed from the outside is not desirable from the standpoint of crime prevention. Therefore, it seems that some proposals have been made in the past to prevent the removal of shoji in the outward direction, but in these conventional shoji, window frames (or inner shoji) are attached to the inner surface of the lower stile. ), it is common to form a large overhanging part that engages with the shoji (shoji).With this type of structure, the lower stile of the shoji is significantly deformed, so it is necessary to manufacture a special shape. It has the disadvantage that its manufacture and handling are not easy.

The present invention has been devised after repeated studies in view of the above-mentioned circumstances, and the specific embodiment thereof is explained as shown in the attached drawings. In the window frame 10 formed by the window frame 10, rail parts 21 and 22 are formed integrally with the upper frame 11 and the lower frame 12, respectively, facing each other, and the shoji 8 is fitted into and runs on such rail parts 21 and 22. However, such a shoji 8
As shown in FIGS. 2 and 3, the lower frame 1 has a fitting depth of its inner flange 1a to the rail portion 22.
H' is larger than the fitting depth h of the upper frame 2 to the rail part 21 of the upper frame 11, and the fitting depth H of the outer flange 1b to the rail part 22 is smaller than the fitting depth h. has been done. In addition, as shown in FIG. 1, when the shoji 8 is closed in the window frame 10, a stopper as shown in FIG. 2 and FIG. A block 4 is removably attached to the block 4 by a screw 5, and the stoppers 6 and 7 are attached to the indoor side of the lower frame 11 as shown in FIG. A concave groove portion 11e formed in the block 4 so as to partially engage the block 4.
However, one stopper 6 is fixed in line with the set position of the stopper block 4 as described above, while the other stopper 7 is fixed at least at a width greater than the width of the matching stile 8c of the shoji 8. It is fixed at a sliding interval l.

In addition, in the embodiment described above, another inner shoji 8a is arranged to run between the upper and lower rails of the window frame 10 as described above, in addition to the shoji 8 described above. The device according to the present invention adopts the above-mentioned structural relationship regardless of the presence or absence of the inner shoji 8a, and obtains the functions and effects described below. It is clear that this also applies to cases where the shoji (or fixed shoji) are installed. Regarding the removable mounting structure using the screw 5 described above, it is sufficient to fix the block 4 in the position shown by the solid line and the position shown by the imaginary line in FIG. Since it is made of synthetic resin with elasticity, it is possible to adopt a locking structure that utilizes a wedge-shaped protrusion and its engagement hole, and in such a case, it is not necessary to use the stopper.

To explain the operation of the device according to the present invention, as described above, the fitting depth H' of the inner flange of the lower stile 1 of the shoji 8 is greater than the fitting depth h of the upper stile 2, and moreover, it does not come loose. Since the stop block 4 is provided at the location where the connecting frame 8b of the shoji 8 is located in the closed state, it is possible to properly prevent the removal of the shoji 8 toward the outside; that is, generally the lower stile 1 The inner flange 1a prevents the removal of the shoji 8 toward the outdoors, and temporarily prevents the removal of the shoji 8 from the lower stile 1.
Even if you try to remove the shoji 8 in the outdoor direction by first removing the upper stile 2 part from the rail part 22 toward the indoor side, the locking block 4 is installed in the position described above. In the completely closed state, the block 4 is fixed even when the shoji 8 is moved in the direction of arrow A in FIG. 3 from the state shown in FIG. 1 or 3.
to any part of the lower stile 1 to prevent the lower stile 1 from coming off the lower frame rail part 22,
In the end, no matter how you try, the shoji 8 cannot be removed from the window frame 10. However, when it becomes necessary to remove the shoji 8, the locking block 4 is moved in the direction of arrow B in FIG. 3 and set as shown by the imaginary line. As shown in FIG. 4, once the lower frame 1 is removed from the lower frame rail part 22, the inner flange 1a
falls into the recessed part inside the rail part 22, and therefore the upper stile 2 and the upper frame rail part 21 are disengaged, and the shoji 8 can be removed from the window frame 10.

When using this invention as explained above, the shoji 8
By making a slight change to the flange portion of the lower stile 1 and using a small retaining block 4, it is possible to effectively prevent the removal of the shoji 8 toward the outside; This is a highly effective device in terms of practical production, since it is possible to prevent the desired removal of the shoji in the outdoor direction without making any essential changes to 12, and with a configuration that is easy to manufacture and handle. .
