The present invention is a fully closed, high safety closed door and door buffer hinge device

In more detail, the present invention relates to a closed door and a door buffer hinge device which can be automatically closed while the door hinge is aligned with the rotation axis of the door frame.

A hinge is installed between the door and the door frame to rotate it, and the door and door frame must be aligned to be closed when it is closed. This is inevitably caused by a gap between the door and the door frame when the door is opened. If it is caught, it can be the first step of a serious safety accident, and in the case of fire doors, the sealing force is vital, and therefore, a hinge structure that can maintain the constant sealing between the door and the door frame is desired.

In general, the shock absorber (door check, etc.) used to dampen the impact of the door is opened only by the spring or the hydraulic pressure to hold the operator to the repulsive force due to the automatic closing of the door was opened when you see the closed state of the door When the door is closed due to the return of rotation, the spring resilience and the rotational return inertia of the character are exactly matched to the door frame and cannot be stopped.After passing the door state, the door frame is shocked, or after several pendulum movements on the inside and outside sides. There was an inaccurate problem in the closing operation. Of course, in order to alleviate this, most of the doors use rubber packings as cushion cushions, but even in this case, when the shocking contact is made for a long time, the packing is broken and a gap is formed, which reduces the sealing force and makes contact with the shocking contact. The durability is drastically reduced.

In addition, as the inaccurate operation is repeated, the closing angle of the door does not exactly match the door frame even after only a short period of time, and the automatic closing operation is not smooth due to the rapid rotational movement, causing breakage or sudden operation of the door. There was a problem that the injury occurred.

Therefore, recently, a door hinge for buffering a door by installing a hydraulic device in the door is disclosed in Utility Model Application No. 1981-0004668, which will be described with reference to FIGS. 1 and 2.
