Description

The present invention relates to a bidirectional door.

In public spaces of modern buildings, the doors used for partitioning are always open, for example, for convenience of access, or for example, access control. Because of this, it is always closed. When an emergency occurs and the evacuees evacuate, the evacuees evacuate by pushing open the door plate intuitively (push, inst of pull) instead of pulling the closed door plate. For this reason, it is necessary for safety to provide a door that opens and closes in both directions, evacuates by opening and closing (Two-way escape route), and prevents the spread of fire by closing the door. .

Conventional single-action door sets can be opened in only one direction. Also, a double-action door plate can be opened both inward and outward. However, the conventional bi-directional door is limited in the rotation angle of the shaft between the door plate and the door frame. That is, when the door plate is opened, the rotation angle is limited by the door frame, and thus the door cannot be opened at a large angle (for example, 180 degrees).

JP 2005-127527 A

The purpose of the present invention is to form a large door including a small door due to the structure including the door plate in the door plate, and the door opening direction of the small door is different from the door opening direction of the large door. It is an object of the present invention to provide a bidirectional open / close door that can be opened and closed in any direction, and can be evacuated by pushing the door set open in any direction or can be closed to prevent fire spread.

In order to solve the above-described problems, the bidirectional open / close door according to the present invention has a structure in which two door frames and one door leaf are combined. A special door set structure having a frame and two door plates is formed. Thereby, the door set can be opened in both directions. That is, the bidirectional open / close door of the present invention has a structure in which a door plate is included in a door plate by connecting two door frames and one door plate by hinges that open and close in different directions. A large door is formed, including a small door. Accordingly, the bidirectional open / close door of the present invention has a small door that opens to the inside (or the left side) and a large door that opens to the outside (or the right side), and therefore pushes the door set in any direction. It can be opened for evacuation or closed to prevent fire spread.

That is, since the door set opens and closes in both the inner and outer directions, the door set can be opened 180 degrees in both directions.

When the conventional door closer is applied to the bidirectional open / close door of the present invention, it is impossible to realize the operation of passing the door set at the same time as pushing it open. Accordingly, the present invention provides a two-way door closer coupled to the inner frame. The bidirectional door closer of the present invention has two slide arms integrated with a mechanism for selecting a door opening direction. Each slide arm is connected to the large frame and the door plate, and has a mechanism that rotates in different directions. Thereby, the bidirectional door closer of the present invention realizes an independent bidirectional door closing effect. Further, the slide arms do not interfere with each other, and the speed adjustment by the buffering action can be freely performed.

The bidirectional open / close door of the present invention is also applied to a door set having two symmetrical door plates. The door asset embodiment only installs the same two-way doors symmetrically. The effect realized in this case is the same as that of the above-described embodiment.

The bi-directional open / close door of the present invention has a gap between the door plate and the door frame like the conventional bi-directional open / close door, causing a security problem or rotating the door plate. When the door plate and the door frame collide, the problem that the door plate cannot be opened at a large angle can be solved. In addition, the bidirectional open / close door of the present invention is not limited to the choice of pushing or pulling (Either push or pull) like the conventional single open / close door. That is, the bidirectional open / close door of the present invention combines the advantages of the bidirectional open / close door and the unidirectional open / close door, and eliminates the disadvantages of the bidirectional open / close door and the unidirectional open / close door.
