Description

Gate device for access control {DEVICE FOR MOTORIZED ACCESS PASSAGEWAYS}

The present invention relates to a gate device for controlling the entrance and exit, more specifically, the rotation section of the inner link for rotating the swing-type gate door left and right symmetrical to prevent the overload of the motor and the impact force acting on the internal structure The present invention relates to a decreasing gate control device.

In general, the entrance of an organization such as a corporation or a government office that requires strict control over visitors by handling confidential data, or the entrances of facilities such as subways and amusement parks that are operated by a large number of people and operated by a large number of visitors. In order to prevent security personnel from delaying access time and to systematically manage a large number of visitors, security personnel can use the magnetic ticket or RF card to automatically access the access passage. A gate device that opens or closes is installed.

Conventionally, a turn type gate has been mainly used, and recently, various structures such as a slide type gate and a swing type gate according to a gate door opening and closing method are used. Gate devices are also used.

In particular, the swing type gate is a gate device that opens and closes an access passage by driving a gate door using forward and reverse rotation of a motor, and a structure of a conventional swing type gate is illustrated in FIG. 1. In other words, the conventional swing type gate moves the gate door 1 connected thereto according to the forward and reverse rotation of the motor to an open state (solid line display) or a closed state (dashed line display) to open and close the access passage.

However, the conventional swing type gate has a structure in which the rotating structure (A↔B) of the inner link that opens and closes the gate door is biased toward the access passage side, so that when the access passage is closed (A → B), Since the gate door 1, which was connected at an angle substantially perpendicular to the ground, should be rotated upwards, there was a problem in that a large load was applied to the motor to rotate the gate door 1 made of a heavy material such as tempered glass during repeated use. .

On the other hand, when switching to the open state (B → A), the gate door 1 is rotated to be biased downward, so that the gate door 1 is connected to the internal structure of the gate casing 2 into which the gate door 1 is retracted. There is a problem that the shock absorber is to be additionally provided in order to reduce the impact applied to the internal structure according to the repeated impact is applied.

In addition, there is a problem that a difference in rotational speed occurs between the case where the gate door is rotated upward by the rotation structure of the inner link biased toward the access passage side and the access passage is closed when the gate passage is closed downward.

In addition, the conventional swing type gate has a problem that the internal structure of the gate device is complicated and the production cost increases because the locking device for maintaining the open and closed state of the gate door (1) must be installed separately.

The present invention devised to solve the above problems of the conventional gate device, the durability is increased by making the rotation section of the inner link for rotating the gate door to be approximately left and right symmetry without deflecting in the direction of the access passage. The rotation speed of the gate door is kept the same.
