Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an accordion door fixing device for fixing an end of the accordion door to the side of an opening.

Conventionally, accordion doors have been fixed to the sides of openings only by the adsorption force of magnets, which has the disadvantage that accordion doors tend to separate from the pillars or walls that form the sides of openings.

The present invention was devised in view of the above-mentioned conventional drawbacks, and its purpose is to secure the end of the accordion door by hooking the hook of the fixing fitting onto the locking part of the end of the accordion door. It can be fixed to the side of the opening, so even if an external force is applied to the accordion door, the end of the accordion door will not come off the side of the opening.Furthermore, the fixing fittings are rotatable, making it possible to secure and fix the accordion door. To provide a fixing device for an accordion door that can be easily released.

The present invention will be explained in detail below using examples.

In the figure, reference numeral 2 denotes a fixing metal fitting, which is L-shaped and has a hole 6 bored in the corner of the L-shape, and the vertical piece 7 and the horizontal piece 8 of the L-shaped fixing metal fitting 2 are connected to each other. Each tip is bent into a U-shape, and approximately half of the bottom piece 10 of this U-shaped bent portion 9 (in FIG. The hook portion 5 is a portion of the outer piece 11 of the U-shaped bent portion 9 that protrudes from the bottom piece 10 by cutting off the lower half.

That is, the hook portion 5 at the tip of the horizontal piece 8 projects clockwise from the hole 6, and the hook portion 5 at the tip of the vertical piece 7 projects counterclockwise.

A steady rest protrusion 12 is provided on the inner surface of the hook portion 5.

The fixing bracket 2 with the above configuration is screw 13 from JL6.
It can be rotatably mounted by inserting and screwing into the pillar or wall 14 on the side of the opening 1.

A runner 16 of the accordion door 3 is attached to the upper rail 15 of the opening 1 so that it can run freely.

An end member 18 having handle protrusions 17 on both sides is provided at the end of the accordion door 3.

The end member 18 is made of metal or synthetic resin and has a substantially U-shaped cross section, and an end core material 21 is sandwiched between the end pieces 19 of the leather 20 through the ends of the leather 20. A hollow portion 23 is formed between 22 and the end core material 19.

The end face piece 22 is concavely bent toward the end core member 21 side, and the upper end of this concavely curved portion 24 is cut out to form the locking portion 4.

Thus, the end member 18 of the accordion door 3 is inserted into the opening 1.
Place the end of the accordion door 3 against a pillar or wall 14 on the side of the accordion door, and in this state rotate the fixing bracket 2 to hook the hook 5 provided on the horizontal piece 8 side to the locking part 4. 14.

In this case, the steady rest protrusion 12 on the inner surface of the hook portion 5 is pressed against the inner surface of the end piece 22 to provide a steady rest and prevent it from wobbling.

On the other hand, to release the fixation, the fixing metal fitting 2 is rotated in the opposite direction to remove the hook part 5 from the locking part 4.

In this embodiment, the hook portions 5 are provided at both ends of the L-shaped fixture 2, but this is not possible when the fixture 2 is installed as shown in Figure 1 or as shown in Figure 2. This is so that it can be used in any case.

Further, only one end of the accordion door 3 may be fixed to the side of the opening 1 using the above-mentioned fixing metal fitting 2, and the other end of the accordion door 3 may be detachably attached using a magnet.
Alternatively, both ends of the accordion door 3 may be fixed to both sides of the opening 1 with fixing fittings 2, respectively.

In the present invention, as described above, the fixing metal fitting is rotatably attached to the side of the opening, and the hook part of the fixing metal fitting can be freely hooked to the locking part provided at the end of the accordion door. Compared to conventional doors that are fixed using magnets, the accordion door is more securely fixed and will not come off even if an external force is applied to the accordion door.Furthermore, the fixing bracket is rotatable, so the fixing bracket can be rotated in the opposite direction. This has the advantage that the end of the accordion door can be unfixed, and in addition, by inserting a screw into the hole in the corner of the L-shaped fixing bracket, attach the fixing bracket to the side of the opening using the above screw. It is rotatably mounted, and the hook part provided on the horizontal or vertical piece of the L-shaped fixing bracket can be freely hooked onto the locking part provided at the end of the accordion door, so the hook part can be used to lock the accordion door. When hooking to the locking section, the vertical piece or the horizontal piece that is not hooked to the locking section can be used as an operation piece that is operated by holding it in the hand, and by rotating the fixing bracket, the hooking section can be moved to the locking section. It has good operability for hooking on and removing the hook, and it is also easy to operate in a clockwise direction around the hole of the fixing bracket at the tip of either the vertical or horizontal piece of the L-shaped fixing bracket. Since a protruding hook part is provided and a hook part protruding in a counterclockwise direction is provided at the other end,
As shown in Figures 1 and 2, even if the fixing bracket is attached to either the front side or the back side of the accordion door, the hooking part of either the vertical piece or the horizontal piece can be freely hooked to the locking part of the accordion door. It has the advantage of being able to be used either front or back with just one type of fixing metal fittings.
