Description

[Detailed description of the invention] (Technical field) The sliding door shoji opening degree limiting device according to this invention is suitable for use in buildings where there is a risk of people falling if opened wide, such as windows in children's wards or psychiatric wards. The opening of the sliding door shoji installed at the opening of the building is limited to an extent that prevents people from falling.

(Background of the idea) If the windows of children's wards and psychiatric wards are made so that the shoji screens can be opened wide, there is a risk that hospitalized patients may fall into them. For this reason, lattices were traditionally installed on the outside of shoji screens, but in recent years such lattices have become less effective as they give the hospital a bad image and impede rescue efforts in the event of an emergency such as a fire. As a result, it became necessary to use other means to prevent patients from falling.

(Object of the present invention) In view of the above-mentioned circumstances, the present invention aims to provide an opening degree limiting device for a sliding door shoji that allows the sliding door shoji itself to be opened only to the extent that a person cannot pass through.

(Structure of the present invention) The opening degree limiting device of the sliding door shoji of the present invention has a guide bracket fixed to the upper stile of the sliding door shoji, which has a cross section that can freely slide in the length direction of the upper stile and rotate about the central axis. It supports a circular retaining rod. One end of this retaining rod passes through the upper end of the vertical stile connected to the end of the upper stile, and the part that protrudes outward from this vertical stile is L.
It is bent into a letter shape to form a hook, which can be freely engaged and detached from a locking tool fixed to the upper end of the inner surface of the vertical frame of the window frame. On the other hand, a stopper is provided at the other end of the retaining rod to prevent the retaining rod from slipping out of the guide bracket. The locking tool fixed to the upper end of the inner surface of the vertical frame has a locking piece on one side of the board for locking the hook at the end of the locking rod, and the locking piece further includes a locking piece for locking the hook at the end of the locking rod. A stopper is provided to prevent the hook from accidentally coming off.

(Operation of the present invention) The opening limit device of the sliding door shoji of the present invention constructed as described above usually locks the hook portion at the end of the locking rod to the locking piece on the side of the locking device. . As a result, the upper stile and vertical frame of the sliding door shoji are connected via the guide bracket, retaining rod, and locking tool. For this reason, the shoji can only be opened and closed within the range until the stopper at the end of the locking rod collides with the guide bracket, and by appropriately determining the length of the locking rod, the opening degree of the shoji can be controlled (for example, 10
cm).

When fully opening the shoji for cleaning, etc., if you remove the stopper of the locking tool and remove the hook at the end of the locking rod from the locking piece, the opening of the shoji will not be restricted by the locking rod. This will allow you to fully open the sliding shoji door.

(Embodiments of the present invention) Next, the present invention will be explained in more detail while explaining the illustrated embodiments.

FIG. 1 is a perspective view showing an embodiment of the present invention.
A guide bracket 1 for fixing to the upper stile of a sliding door shoji is made integrally by die-casting of aluminum, for example, and has mounting flanges 4, 4 at both ends of a main body 3 having a through hole 2 with a circular cross section in the center. Each mounting flange 4, 4 is provided with a screw hole 5, 5 into which a screw for fixing the guide bracket 1 to the upper frame is screwed.

The through hole 2 provided in the main body 3 of such a guide bracket 1 has a length that is sufficiently longer than the entire length of the main body 3 (for example, about 10 to 20 cm, although it varies greatly depending on the opening degree of the shoji and the mounting position of the guide bracket 1). ) A long retaining rod 6 is inserted so that it can freely rotate and slide along the length of the main body 3. Of both ends of the retaining rod 6 that protrudes outside the through hole 2, one end is bent at right angles to form a hook portion 7, and the other end is bent to form a hook portion 7 to prevent the retaining rod 6 from coming out of the through hole 2. A stopper 8 is provided.

On the other hand, a locking tool 9 for locking the hook of the end of the locking rod supported on the guide bracket 1 in this manner
As shown in FIG. 1 and FIGS. 2 and 3, a locking piece 11 is fixed to one side of a board 10 for fixing to the inner surface of a vertical frame, and a locking piece 11 is fixed to the corner of the board 10. Circular holes 12, 12 for screw insertion are bored. The locking piece 11 fixed to the center of one side of the board 10 is attached to the end of the base 11a fixed to the board 10.
A locking portion 11b is provided which is bent at right angles to the base portion 11a and is parallel to the substrate 10.
A gap 13 is formed between the locking rod 1b and the board 10 into which the hook 7 at the end of the locking rod can freely enter.
The height of b is lower than the height of the base 11a, and an arc-shaped notch 1 is formed at the connecting part of both parts 11a and 11b.
4 is formed. The board 10 is attached to the locking portion 11b.
A screw hole 15 is provided in a direction perpendicular to the screw hole 15, and a screw 16 which acts as a stopper for preventing the hook portion 7 from coming off is screwed into the screw hole 15.

Of the parts configured as described above,
The guide bracket 1 supporting the retaining rod 6 has the fourth to
As shown in Figure 5, a screw 1 is inserted from below through a small hole drilled in the horizontal part 17a of the upper stile 17 of the sliding door shoji.
8, 18 into the screw holes 5, 5 of the mounting flanges 4, 4 and tighten them, the horizontal portion 17a
It is fixed to the top surface of the end. The end of the retaining rod 6 on the side of the hook 7 extends further outward than the end of the upper stile 17, and has a through hole formed at the upper end of the vertical stile 119 or a notch for passing through the upper guide rail. It protrudes to the outside of this vertical stile 19 through.

On the other hand, as shown in FIGS. 4 and 6, the locking tool 9 is inserted into the circular holes 12, 12 at the corners of the board 10 with screws 21 while the board 10 is in contact with the inner surface of the vertical frame 20. . By doing so, it is fixed to the inner surface of the vertical frame 20.
