Abstract

PROBLEM TO BE SOLVED: To prevent a folding door from being moved even when a force is applied to a closing end by projecting an insertion shaft provided on a corner of the folding door, and fitting it into a hole provided in a lower floor when the folding door is closed. SOLUTION: When a folding door 1 is opened, a lever 5 is pushed out by a spring 6, and an insertion shaft body 3 is pressed in against a spring 4 by a pin 5a. When a pair of folding doors 1 are closed, both levers 5 are abutted on each other and pressed in, and the insertion shaft body 3 is projected by the spring 4 because a cam hole 3a is engaged with the pin 5a of the lever 5. An insertion shaft 3b of the insertion shaft body 3 is fitted to a hole provided in a lower floor 9. As a result, the folding door is not moved even when a force is applied to a closing end of the folding doors 1 in a condition where the folding doors 1 are closed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door stationary and earthquake-resistant device for preventing a closed end from moving when the folding door is closed.

[0002]

2. Description of the Related Art Conventionally, when a folding door is closed, particularly in the case of a hanging type folding door, the door has been moved even if a slight force is applied to the closed end.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a folding door stationary and anti-seismic device which keeps the closed end from moving when the folding door is closed. Another object of the present invention is to provide a folding door stationary and anti-seismic device that keeps a closed state in which a closed end does not move even during an earthquake.

[0004]

According to the present invention, there is provided an insertion shaft body provided at a corner of a folding door and capable of projecting by a spring, a cam hole of the insertion shaft body, and a cam hole. The present invention proposes a folding door stationary and anti-seismic device comprising a lever provided on a mating end face of a folding door and having a lever protruding from a mating end face of the folding door and a spring for pushing out the lever when the insertion shaft main body is protruded by the pin when engaged with and pushed into the folding door. Things.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a folding door stationary and earthquake-resistant device according to the present invention. FIG. 1 shows a folding door stationary and anti-seismic device according to the present invention, wherein the folding door stationary and anti-seismic device (2) is provided with an insertion shaft body ( 3). The insertion shaft main body (3) is provided with a cam hole (3a) which is inclined obliquely and converts the movement into a right angle. On the other hand, a lever (5) is provided so as to protrude from the mating end face of the folding door (1) (to be fitted when the pair of folding doors (1) is closed).
The lever (5) receives a force in a direction pushed by a spring (6) (stronger than the spring (4)). Further, a cam hole (3a) of the insertion shaft main body (3) is provided in the lever (5).
Is provided with a pin (5a) that engages with the pin. Next, when the lever (5) is pushed in, the pin (5a) allows the insertion shaft main body (3) to protrude. The operation of the folding door stationary and earthquake-resistant device shown in the above embodiment is as follows. That is, when the folding door (1) is open as shown in FIG.
Is pushed out by a spring (6). Therefore, the pin (5a)
As a result, the insertion shaft main body (3) is pushed in against the spring (4). Next, as shown in FIG. 2, when the pair of folding doors (1) are closed, their levers (5) come into contact with each other and are pushed in. As a result, since the cam hole (3a) is engaged with the pin (5a) of the lever (5), the insertion shaft main body (3) protrudes with the spring (4). Next, a hole (8) is provided in the floor (9) below the position where the pair of folding doors (1) are closed. Therefore, the insertion shaft (3b) of the insertion shaft main body (3) is fitted into the hole (8) of the floor (9). As a result, folding door (1)
When the is closed, it does not move even if force is applied to the closed end of the folding door (1). FIG. 3 shows another folding door stationary and anti-seismic device according to the present invention. The same is true.

[0006]

The embodiments of the folding door stationary and anti-seismic device of the present invention are as described above, and the effects thereof are listed below. (1) In the folding door stationary and anti-seismic device of the present invention, especially when the folding door is closed, the insertion end is inserted into the hole in the floor, so that even when force is applied, the closed end of the folding door does not move. (2) The folding door stationary and anti-seismic device of the present invention does not hinder opening and closing because the insertion shaft is retracted particularly when the folding door is opened. (3) The folding door stationary and anti-seismic device of the present invention keeps the closed state without the closed end moving even in the event of an earthquake, especially when the folding door is closed, since the insertion shaft is fitted into the hole in the floor.
