Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a mechanism for preventing a shoji from coming off, which is provided in the lower frame of a sash.

[Technical background of the invention and its problems]

In the recent era of low growth, buildings and other structures are required to have improved durability and ease of maintenance to ensure durability. For example, when looking at windows on the exterior walls of buildings, many have a flat design similar to a curtain wall. In addition, opening/closing type windows have a fixed part and a movable part, and depending on the shape of the movable part, there are known types such as revolving windows, outward-folding windows, inward-folding windows, sliding windows, and single-sliding windows. These windows are also required to be maintainable, with a mechanism that allows the shoji to be flipped 180 degrees or to allow the shoji to open inward.

In particular, with sliding windows, it is necessary to remove the shoji during maintenance such as cleaning or replacing the glass, but with conventional windows, the shoji is removed from the outside before being put inside the room, so the shoji is not exposed to the outside. They can fall off, which can cause accidents, especially on high windows. In addition, with sliding windows, a part to prevent the shoji from falling off is usually installed on the sash to prevent the shoji from coming off the sash. Because of this, there was a risk that the shoji could sometimes be forgotten and the shoji could fall off. Furthermore, in buildings used by children, such as schools, accidents can occur where shoji doors fall off due to intentional removal of falling-prevention parts due to mischief, or due to forced operation. There were also other dangers.

In order to prevent this, a mechanism has been proposed that prevents the shoji from sliding outward by making the outer rail of the lower frame higher than the inner rail and riser, and changing the length of the outer lower stile from inside to outside. In this case, since the shape of the lower frame of the sash is not common, there was a drawback that the shape of the lower frame was complicated in order to ensure watertight performance.

[Purpose of invention]

The present invention was proposed in view of the above-mentioned problems.The purpose of this invention is to enable maintenance work to be carried out safely, to prevent the shoji from falling off even in reckless operations, and to solve the basics of general sash. To provide a mechanism for preventing a shoji from coming off, which hardly changes the shape of the shoji.

[Summary of the idea]

The shoji removal prevention mechanism of the present invention is provided with a support part on the outdoor side of the lower frame of the sash, an auxiliary member arranged so as to be rotatably engaged with this support part, and this auxiliary member When hanging a shoji, even if it is fixed vertically on the sash lower frame and the rising part of the shoji is lifted all the way to the top of the upper frame, the shoji's lower stile will not be able to get over the auxiliary material. This size prevents the shoji from falling to the outside of the room.

[Example of idea]

Next, one embodiment of the present invention will be explained in detail based on FIGS. 1 and 2.

First, a sliding window is built into an opening formed in a building.
and a sash consisting of a lower frame 4 provided with inner and outer lower rails 3, 3' and left and right vertical frames 5, 5';
It consists of inner and outer shoji 6, 6' assembled between the upper and lower rails 1, 1', 3, 3' of this sash. These shoji 6, 6' have glasses 10, 1 incorporated in the upper stile 7, 7', the lower stile 8, 8', and the left and right vertical stile 9, 9'.
It is formed from 0'.

In the shoji removal prevention mechanism of this embodiment, which is provided in the sash as described above, an opening 11 is provided further on the outdoor side of the outdoor side rail 3 of the lower frame 4 at the bottom.
A support portion 12 having an arcuate cross section is provided, and the lower part of the auxiliary member 13 is secured to the support portion 12. This auxiliary member 13 has an L-shape consisting of a base portion 13a and a rising portion 13b.
A screw hole 14 is provided at the center of the lower surface of a. A semi-circular locking portion 15 whose tip is curved toward the indoor side is provided on the indoor side of the screw hole 14, and a hook-shaped retainer 16 is formed at the tip of this locking portion. ing. The inner diameter of the locking portion 15 is set to be substantially the same as the outer diameter of the support portion 12, and a stopper 16 at the tip of the locking portion 15 is engaged within the opening 11 of the support portion 12. The auxiliary material 13 is fixed to the lower frame 4 by screws 17 inserted into the screw holes 14 from the vertical frame 5 side.

Furthermore, the rising dimension C of the auxiliary material 13 is set to the swallowing dimension of the upper frame 2 so that the lower stile of the shoji does not go over the auxiliary material 13 even when the shoji is lifted up to the maximum of the upper frame within the sash. The swallowing dimensions A and B of the upper and lower frames 2 and 4 and the rising dimension C of the auxiliary material 13 are formed to be longer than the swallowing dimensions B of the upper and lower frames 2 and 4 so that the shoji can be removed indoors.
The relationship is considered to be C>A>B. Then, the rising portion 13b of this auxiliary material 13
This serves as a guide rail for the screen door 19 together with the rail 18 provided on the outdoor side of the upper frame.

In this embodiment, the base portions 13a are provided only at both ends of the auxiliary member 13, and the center portion of the auxiliary member 13 is open to form a drain hole 20.

In this way, in the shoji removal prevention mechanism of this embodiment, the swallowing dimension when removing the shoji is A>B.
If so, it can be removed both indoors and outdoors, but by providing the rising part 13b on the bottom frame itself so that C>A>B dimensions, the auxiliary material acts as a guide to prevent the shoji from being removed. Since it can only be operated from inside the room, maintenance work can be carried out safely. In addition, not only has the risk of the shoji falling off due to rough opening and closing been eliminated, but
It has the advantage that it can also be used as a screen door rail.

Note that this embodiment is not limited to the above-mentioned fixed type of auxiliary material. For example, as shown in FIGS. When work is necessary, this can be removed so that work can be carried out.

That is, in the embodiments shown in FIGS. 3 and 4, the base portion 21a of the auxiliary member 21 is formed in a T-shape horizontally with respect to the rising portion 21b, and the base portion 21a has a screw hole-shaped bearing 22 at its tip. A screw hole 23 is provided in the center. Further, the lower end of the rising portion 21b is bent inward in an L-shape to form a stopper portion 24. The auxiliary member 21 is rotatably supported by the lower frame by inserting the rotating shaft 25 provided in the vertical frame 4 into the bearing 22, and the fixing screw 26 inserted into the screw hole 23 It is fixed by the tip touching the bottom frame. Therefore,
When the auxiliary fixing screw 26 is removed from the indoor side as required during maintenance, the auxiliary material 21 falls toward the outdoor side around the rotating shaft 25, and the rising portion 21b
Since it is locked to the lower frame 4 by the stopper part 24 at the base end of the shoji, the shoji can be removed from the outside without the auxiliary material falling off from the lower frame.

Also, instead of the fixing screw 26 in the above embodiment, a fifth
As shown in Fig. 6, the auxiliary material 3 has a horizontal T-shape.
The lower part of the rising part 31 of 1 is curved toward the indoor side, a screw hole 33 is provided in this curved part, and the fixing screw 36 inserted here is brought into contact with the lower frame, so that the auxiliary material can usually be fixed. . In this case, fixing screw 3
6 cannot be operated from inside the room, so there is no risk of the fixing screw being removed by mischief or the like.

As mentioned above, in the examples shown in Figures 3 to 6, there are cases where handrails are installed on the indoor side, where furniture etc. are placed and the cabinet is higher than the bottom frame, and where external work is required. In such cases, the auxiliary material can be rotated toward the outdoor side and the shoji can be removed to the outside. Moreover, after the shoji has been removed, the auxiliary material can be easily assembled.
