Rotary gate with locking arm which can swing parallel to main rotation shaft

Abstract

The invention relates to a rotary lock which is used to control the passage of people and comprises a locking unit that can be blocked and unblocked, can be rotated about an inclined rotational axis, and comprises preferably three blocking arms (2) which can successively, in progressive steps, be brought from a position blocking the passage of a person into a position freeing the passage of a person. In the event of a breakdown or danger, the unhindered passage of any number of people is enabled by locking a respective blocking arm (2) on a bearing plate (4) carrying the blocking arms (2) in an articulated manner (4), by means of a locking element (7) engaging in an opening (8).; In the event of a breakdown, the locking element (7) of the blocking arm (2) located in the blocking position is mechanically released from the engagement in the opening (8), and an eccentric force applied to the blocking arm (2) pivots the same out of the normal position thereof into the release position thereof. When the breakdown is over, the blocking arm (2) in question is temporarily blocked and automatically brought back into the normal position thereof by rotating the bearing plate (4) by less thana progressive step, as a result of the forced rotation thereof in relation to the bearing plate (4).

Description

technical field [0001] The invention relates to a turnstile for the control of the passage of persons, which is rotatable about an axis of rotation inclined downwards at an angle of approximately 45° to the horizontal and which can be prevented from being locked in rotation by a releasable locking mechanism and can be A locking unit that is released for rotation in at least one direction of rotation, the locking unit having at least two locking arms inclined towards the axis of rotation, of which there is always one locking arm in the operating position of the device Positioned in a substantially horizontal blocking passage position with the other blocking arms moved out of the passage area, wherein the blocking arms are successively movable from the blocking passage position to the open passage position by the rotation of the blocking unit due to the command to the releasable locking mechanism, and the The locking arm is hinged on the support plate of the locking unit in this...

Problems solved by technology

[0008] A further disadvantage of the above-mentioned known cross gate devices is the drive by means of an electric motor with a transmission, which, depending on the type of transmission, emits unpleasant noises and is subject to high wear

In order to continue to turn the locking unit, a high power consumption is required
