Abstract
A device for locking a sliding body, such as a retractable road boundary-mark, in at least two predetermined positions towards which the device is urged by a controller. The device includes a locking rod extending parallel to a sliding axis of the sliding body and rotatable about a longitudinal axis thereof. The locking rod has a plurality of transverse notches whose number and mutual distance along the rod are equal to the number and the mutual distance of the predetermined positions and which are angularly spaced from each other about the longitudinal axis of the rod.
Claims8
A device for locking a sliding body in at least two predetermined positions towards which the device may be urged by a control device acting on a locking body which extends parallel to a sliding axis of the sliding body and which rotates around its longitudinal axis but cannot move parallel thereto, the device comprising:
- a plurality of transverse notches formed on the locking rod and whose number and mutual distance along said locking rod are respectively equal to a number and a mutual distance of said predetermined positions, said notches having a bottom which is convex and is linked with side surfaces of said locking rod, said notches being angularly spaced from each other about the axis of said locking rod when viewed from a lengthwise direction of the locking rod;
- and
- a bolt means cooperative with said plurality of transverse notches and attached to said sliding body, said bolt means engaging said notches by a pressure of a spring such that the rotating of said locking rod around its axis brings the bolt to the predetermined angular positions where one of said transverse notches opens outwardly toward said bolt means.
