ABSTRACT:
This concerns a hinge mechanism comprising a fixed end plate, a movable end plate lockable by two wedges controlled by a sliding pushrod, itself activated by pivoting of a control plate in a first or second direction in order to free the movable end plate. A circular guide comprises radial breaks receiving the wedges, and holding the wedges in a withdrawn position when they disengage from the radial breaks under the pivoting effect of the control plate in the second direction, which fixes in addition the circular guide to the movable end plate. The movable end plate can thus turn freely before relocking in its initial angular position when the radial breaks of the circular guide return opposite the wedges.
