DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-sided door that opens on both sides inside and outside and has an automatic stopper that stops completely at a fixed stop position.

[0002]

2. Description of the Related Art Various types of doors, such as sliding doors, single doors, and single door type double doors, are used at entrances and exits of buildings. And doors are used.

[0003] Many entrances and entrances of houses, such as general houses, which use a single-door type door, mainly open or close only in a single direction, ie, pull open or push open. For example, from the inside to the outside in any direction, such as a one-sided door used for entrances of buildings where many people enter and exit, such as public buildings, halls, hospitals, department stores, superstores, convenience stores, etc. Entrance doors that can be opened or pushed open are also used.

[0004] The automatic closing means of the one-sided door includes:
Generally, the one that automatically closes using the return resistance of a fairly strong spring or other elastic body is often used. It is used.

[0005]

However, in the case of a single-opening inner / outside double door that is opened by tilting and closed by its own weight, the automatic doors that are automatically closed by their own weight do not stop at a fixed closing stop position without overrunning. Then, there is a drawback that it stops after repeated inward and outward swing motions several times.

Therefore, when a person who tries to enter and exit next waits at the closed door fixed position while returning to the door that was opened by a person who has entered and exited earlier, and thinks that the door will stop, the stop is determined. There is also a danger of being overturned by the overrunning door without stopping at the position. For example, if a wheelchair user, a walking aid user such as a crutch, or an elderly person misunderstands the door, it is even more dangerous.

In particular, a one-sided double-sided door provided for constructing a barrier-free doorway needs to be provided with a function of reliably stopping once at a fixed closing stop position even if the door is suddenly closed in any situation. there were.
