Description

[0001] The present invention relates to a swing type gate apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate device installed to open and close an access passage, and more particularly, to a swing type gate device that alleviates a link shock due to rotation and reduces vibration and noise.

Conventionally, a manager or a security officer checks and controls the passengers at the entrance of a building such as a corporation or a government office, or at the entrance of a facility such as a subway or an amusement park. There was a problem of delays in access time, and there was a problem of waste of manpower to arrange a plurality of managers or security personnel for access control.

In order to prevent delays in access time due to the control of many passengers by a manager or a security officer and to systematically manage a large number of passengers with a small number of personnel, a large number of passengers who are permitted to access are required to use magnetic tickets or RF cards When an identification card is desired to be accessed, a gate for automatically opening and closing the access passageway is installed as the recognition through the identification card succeeds.

In recent years, turn type gates have been mainly used. In recent years, various types of structures such as a slide type gate and a swing type gate have been proposed in accordance with the gate door opening / Gate is used.

Particularly, the swing type gate is a gate for opening and closing the entrance and exit passage by driving the gate door using the forward rotation and the reverse rotation of the motor, and the structure of the conventional swing type gate is shown in FIG. That is, the conventional swing type gate opens and closes the gate by moving the gate door 1 to the open state (solid line display) or the closed state (dotted line display) by the driving force of the motor in accordance with the forward rotation and the reverse rotation of the motor . However, since the conventional swing type gate has a structure in which the rotation structure (A↔B) of the inner link for opening and closing the gate door is biased toward the entrance and exit path, when the entrance and exit path is closed (A → B) The gate door 1, which has been connected at an approximately perpendicular angle to the ground, has to be rotated with the upper side biased. Therefore, a problem is that a lot of load is applied to the motor for rotating the gate door 1 made of heavy material such as tempered glass there was.

In addition, the conventional swing-type gate door has a problem that the gate door 1 is subjected to repetitive impact due to a deflection rotation during opening and closing, and thus a shock absorber for reducing the impact has to be additionally provided. In addition, there is a problem in that the rotational speed difference occurs when the gate door 1 is opened or closed by the rotation structure of the internal link biased toward the entrance / exit passage, There is a problem that the internal structure of the gate device becomes complicated and the production cost increases.

Korean Patent No. 10-1289390 discloses a structure for solving the problems of the swing type gate of FIG. 1, wherein the rotation of the internal link for opening and closing the gate door is symmetrical in the left and right directions, A structure in which a force acting on an internal link is reduced and a failure of the gate device is reduced. However, according to the registered patent, the crank mechanism is used to transfer the rotational force generated by the motor to the door. It is possible to prevent the overload of the motor and reduce the failure, thereby increasing the life span and reducing the maintenance cost. Link shock, vibration and noise problems remain.

It is an object of the present invention to provide a swing-type gate device that minimizes link shock, vibration, and noise caused by components operating for a swing of a door.
