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.

Abstract: According to the invention, a bearing for a circular rotatable disc (4) on a support may be achieved by means of several, preferably three rollers (6) which roll on the circumference thereof which are positionally fixed but which may rotate on the support (3). The bearing is simpler and economical to produce is also reliable and hardly subject to wear. The bearing offers optimal guidance and support especially as a three-point bearing.
