Description

Power-free two-way automatic balance door {Two-way automatic balance door}

The present invention relates to a two-way automatic balance door, and more particularly, a two-way automatic door that is installed at the entrance of a building, school, shopping mall, department store, building lobby, etc. uses a large door, so that it can enter and exit more conveniently than a conventional door. It relates to a non-power bidirectional balance door that forms a balance door, opens and closes efficiently within a narrow space between the door and the door frame, minimizes the turning radius of the door, makes automatic closing and entry convenient for users, and has low maintenance costs.

In general, in the case of a door installed at the entrance of a building, in the case of a revolving type, upper and lower ends of one side are rotatably installed in a building or a door frame installed in the building. In the case of a door that is opened and closed in a revolving type as described above, if a separate door fixing device or a door opening/closing shock absorber is not installed, it is easily opened and closed or shakes even by a slight external force such as wind.

When the door is arbitrarily opened or closed by an external force, the possibility of a safety accident such as colliding with the door cannot be excluded, and the door itself also has problems such as being damaged or broken due to the collision. In particular, in the case of such a safety accident, breakdown, or damage, if the door is a glass door to which tempered glass is applied, serious consequences may occur.

For this purpose, a door installed in an entrance, particularly a door, a door floor hinge device that is installed on the floor of an entrance of a building to provide a cushioning force so that the corresponding swing-type opening and closing operation is maintained naturally and slowly is widely used.

Use a door closer that is formed on the upper part of the door so that it can be easily closed when closed. The floor hinge device or the door closer has a structure similar to the operating principle.

In the conventional door closer, a door that can open and close the door freely in one or both directions is installed at the entrance of a building. In such a door, the hinge is restored to the closed state by its own elasticity after the door is opened by an external force. device is installed.

In addition, the present applicant has applied for "Hydraulic floor hinge device for opening and closing a door" in Korean Patent Registration No. 10-1024700. In the disclosed conventional floor hinge device, the piston unit is moved by the cam unit when the door is rotated, and it uses hydraulic pressure to act as a buffer when the door is turned. In the conventional floor hinge device, a cam formed in a cam unit is divided into a round surface and a flat surface. Here, the round surface serves to apply tension to the door by pressing the elastic member, and the flat surface serves as a stopper to prevent the door from being easily opened or closed even when an external force is applied.

Also. In the case of a building with a structure of a sliding door, where entry and exit are frequent, if the door is opened after an entrant passes through the door, the indoor heating and cooling effect is lowered, resulting in significant energy loss, and It can act as a factor that deteriorates the indoor environment, and as one of the ways to overcome this, a floor hinge device with an automatic closing function is applied to the door and used.

Therefore, in order to facilitate construction and not to excavate the floor, it is considered a good method to install a floor hinge device on the top of the door and connect the hinge shaft protruding downward to the top of the door, but connect the hinge shaft to the top of the door In order to solve the problem of not being able to prevent the door from shaking or rattling on the hinge shaft because the hinge shaft and the door cannot be firmly connected because the door's own weight does not act on the hinge shaft, the Many formed doors have been developed.

Since the hinge at the end of the conventional door has a large rotational trajectory of the door, access is possible only when the door is wide open. There was a problem in that it was very inconvenient for people to use it because it had to lift a lot of power or pulling force.

In order to solve this problem, the applicant of the present application has developed an automatic closing type two-way automatic balance door that can enter and exit in both directions and maximize efficiency during heating and cooling because the rotational track is not large, so the action force is small and the outside wind is small when opening and closing. To provide this, a door moving vehicle was formed on the door frame, and a door closer on the side of the door and a hydraulic floor hinge were formed on the bottom to close the door with the hydraulic floor hinge formed on the door.

The configuration as described above is applied to a door that requires little force, and in a large door with a large door, it is not enough to close the door with the hydraulic floor hinge part, so it is preferable to form a large hydraulic floor hinge part that matches it, but manufacturing cost and higher hydraulic capacity There was a problem that installation was difficult because the space for installation was narrow when using the .
