<p>The mechanism is based on two plane and rectangular profiles (4) and (5) fixed to the cabin door (2) and the corresponding door on the floor or storey (3), the said profiles being pushed by the displacement of corresponding rollers (6) and (8) so that when the door (2) is displaced at the commencement of the opening movement, as the roller (8) is associated with a tilting member (9) on which is mounted another novel roller (11) adapted to be propelled by a horizontal arm (12), all so that upon displacement of the door (2), when opening it is commenced, movements of the said elements take place and consequently there is a tilting of the bolt (1) in order to release or unlock the corresponding cabin or floor door (2,3). The mechanism as a whole ensures smooth movements with no rattling of the doors, a reduction in the number of parts compared with conventional systems and the complete elimination of noises caused during the opening and closing of lift doors. <IMAGE></p> |
