ABSTRACT:
The gate system comprises a wicket which is capable of taking up a number of different positions corresponding to predetermined angles of inclination, an operating device comprising a pivotally mounted jack, and a rotatable abutment member carried by the wicket for receiving the end of the operating rod of the jack. The jack is restored to an end position of angular orientation when the operating rod is moved away from the abutment member. This end orientation is close to the orientations of the jack during operation. The operating rod of the jack and the abutment member comprise guiding apparatus for orienting the jack towards the abutment member when the end of the jack-operating rod comes close to the abutment member.
