ABSTRACT:
It is a question of bringing resiliently and successively the arms of a turnstile to their position obstructing a passage to be controlled, and for this a rotary cam 1 in the shape of a star is used interlocked with the rotary assembly of the turnstile and a roller 2 resiliently applied against this cam.
To avoid lifting-off between the roller and the cam, a second contact is used between a second roller 2 connected to the first roller or merging therewith and a second cam 10 connected to the first cam or merged therewith, the directions of application of the two roller-cam contacts being opposite.
The invention applies to controlling access to urban rail networks.
