Description

Two-way automatic balance door {Two-way automatic balance door}

The present invention relates to a two-way automatic balance door, and more particularly, to a balance door that minimizes the door's turning radius and allows automatic closing and convenient entry and exit.

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 opens and closes in a swinging manner 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, more serious consequences may occur.

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

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 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 this case, since the door's own weight does not act on the hinge shaft, the hinge shaft and the door cannot be securely connected, so the hinge shaft cannot prevent the door from shaking or rattling. 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.

The problem to be solved by the present invention is to provide 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. is to do

Another object of the present invention is to be coupled to the frame at the top of the door so that it is automatically closed by being coupled to the lower end of the door moving door so as to move with the door moving door unit having front and rear moving wheels and left and right moving wheels to automatically close. An object of the present invention is to provide a bidirectional automatic balance door in which a flow hinge is formed.

Means for solving the problem of the present invention is

In the balance door formed of a door frame and a door,

an upper rail bar formed so as to support the door by coupling the upper and lower arms formed at the upper and lower portions of the end of the door frame to the upper and lower portions of the door frame, and an upper and lower support bar coupled to the axle to move within the door frame;

The door moving door unit having front/rear moving wheels and left and right moving wheels formed so that it can be moved by being inserted into the upper rain bar, and coupled to the frame at the top of the door so that it is automatically closed by being coupled to the lower end of the moving door moving car to automatically close An object of the present invention is to provide a bidirectional automatic balance door in which a hydraulic flow hinge part for a door is formed as much as possible.

The two-way automatic balance door of the present invention is

By minimizing the turning radius of the door and forming it to expand and open at the same time, it is convenient for the user to enter and close, and there is a useful effect that the user can conveniently enter and exit.

In addition, the hydraulic flow hinge part for the door is installed on the upper part of the door between the both ends rather than at one end, so that it can be easily opened and closed with little force, so that the user can open and close it with little force.

In addition, since the turning radius is small when the front door is opened and closed, there is an effect that less cold or hot air from outside enters the room, which is a very useful invention that can increase the efficiency of heating and cooling.
