The mechanism comprises driving and control slides (23,13) and a control lever (20) coupling them. The driving slide moves on the leaf or the frame in the main plane of the latter, and also at right angles to this plane in opposition to a return force, from the initial position with the door shut into the open one, and the control slide also moves in these directions. The control lever, attached only between the driving and control slides, hinges only on an axis (21,22) at right angles to the main plane of the leaf or frame. The control slide can be arranged to slide only between the arms (11,12) of a guide stirrup (8) recessed into the leaf or frame from the end face. |
