Definitions

  • the present invention relates to a mechanism for locking and releasing closure bolts for automatic doors of lifts, the special design of the mechanism providing a number of advantages from the structural point of view as well as the functional and including the maintenance aspect, compared with conventional systems provided for the same purpose.
  • the locking mechanism is constructed so that it permits a movement of the doors on each floor and of the lifts and of the cabin doors, being firmly connected to one another without any play, during periods of opening and closing. At the same time, the structure of the mechanism is reduced to the minimum in terms of the number of constituent parts, basically in the floor door of the lift.
  • the invention has conceived a locking and release mechanism applicable to automatic doors of lifts for the actuation of the closure bolts, which allows movement of the lift doors at the floor and also of the door of the lift cabin, the doors being firmly connected with no clearance in either direction of movement and during the periods of opening and closure.
  • the mechanism is based on a considerable reduction in the number of elementary parts such as rollers, spindles, moving parts etc., mainly in the lift door at the floor.
  • the mechanism has the particular feature that the buffers for carrying out the said locking and releasing of the bolt are constituted by respective flat and rectangular profiles, one of these belonging to the door at the floor while the other belongs to the door of the lift, between which there is disposed a roller which is rigid with the floor door and on the top and rear of which rests the associated bolt, while externally of the flat profile which is attached to the floor door there is another roller connected to a tilting member which is actuated by the thrust from a straight arm which is part of the cabin door, all so that the distances, in the closed position, between the roller connected to the floor door and the flat profile connected to the cabin door, and also the distance between the roller connected to the cabin door and the flat profile rigid with the floor door, are constant and equal distances which allows the doors to be connected without any clearance of any type, so that no noises are created while smooth movements are obtained without any kind of rattling in the door panels.
  • reference numeral 2 corresponds to the cabin door while reference 3 corresponds to the door at the floor or storey, the references "a” and “2a” corresponding to the distances between the elements which form part of the mechanism and which will be described hereinafter.
  • the actual mechanism includes a flat and rectangular profile 4 which is connected to the cabin door and a similar profile 5 which is connected to the door on the floor or storey, so that Fig. 1 shows the bolt 1 in the locked position and immediately prior to commencement of the movements needed to open or release it.
  • the bolt 1 has its upper and rear part resting on a roller 6 which is connected to the floor door 3, the roller 6 on which it is possible to support and impel a flat and rectangular profile into a vertical arrangement identified by reference numeral 7 and belonging to the cabin door 2.
  • a second roller 8 is also mounted on this cabin door 2, with the particular feature that in this case the said roller 8 is associated with a tilting member 9 which rotates about the spindle 10.
  • the said roller 8 is, according to the tilting of the member 9, capable of acting upon and biasing the end of a straight arm 12 which is part of the cabin door 2, all so that displacement of the profiles 4 and 5 by the action of the rollers 6 and 8 produces a tilting of the bolt 1 in order to release and open the door, in addition to which the connection between them is made without any kind of clearance.
  • Fig. 3 shows the actual bolt 1 in the closed or locked position, clearly demonstrating how the member 7 is constantly biased by a spring 13, the said bolt being associated with a contact 14 combined with a make-and-break switch 15.
  • Fig. 4 shows the rear part of the mechanism where it is possible to see the tilting member 8 and the arm 12 which bears on the roller 11, the said tilting member 9 being biased by the spring 16.
  • the bolt 1 During the process of opening and closing, the bolt 1 will be permanently subject to the control of displacement of the cabin door 2 and therefore its movement is never free, which avoids the typical problem of the noise caused in other mechanisms due to the uncontrolled dropping of the bolt during the final phase of door closure.
