Definitions

  • the invention relates to a manual emergency opening device for automatic doors, in particular for lift and elevator doors.
  • Automatic gates for lifts and elevators are of two types: a first provided with two doors which meet centrally and each open in a centre-to-side sliding motion; the second provided with a single telescopic door subdivided into segments.
  • the doors of each group opening and closing in a same sense, which is opposite to the motion sense of the other group, such that the two door groups move symmetrically with respect to the centre of the lift gate.
  • an unblocking device is provided which enables the door to be manually opened so that the users can exit.
  • This device which acts on the lock mechanism by unlocking it, is activatable from the outside by means of a key inserted into a hole.
  • the hole is made in a usually sheet metal cover situated above the door, at the door architrave, which cover contains the sliding mechanisms of the door or doors.
  • the hole has to be made near the lock of the support and motion carriage of the door, it is made centrally if the door is of the central-to-side type, while it has to be made laterally on the right or the left if the door is telescopic or lateral.
  • the main aim of the present invention is to obviate the above-mentioned drawback by providing a device which enables the hole to be made in a same position such that the cover can be modular, that is, the same whether destined for application to any type of lift or elevator door.
  • a further aim is to provide a manual unlocking device which is in a same, standard position for all types of doors.
  • the opening device of the present invention which is characterised as set out in the following claims and in particular in that it comprises mechanical transmissions which connect the hole with the lock element of the carriage such that the position of the hole is always the same and fixed for any type of door, whether centrally or laterally opening.
  • the above hole is preferably made in the central part of the sliding mechanism cover.
  • 1 denotes in their entirety means for automatically opening and closing doors 2, in particular for lifts and elevators.
  • the means 1 are of substantially known type and comprise a sliding carriage 4 slidable on a guide 9 by means of wheels 11, which carriage 4 inferiorly supports a door 2, applied directly to the carriage (as in figure 1) or indirectly, through support rods 20 (as in figure 2).
  • a carriage lock device 3 is provided to prevent opening of the doors during normal functioning of the lift.
  • Said carriage lock device 3 is constituted by a slot 13 on the carriage itself, into which a hook element 12 solid to the fixed door frame 14 hooks.
  • a known-type device mounted on the door commands the displacement of the slot 13 downawards to effect the unlocking of the carriage and enable it to slide along the guide 9.
  • a manual carriage unlocking device which in the present invention is realized by means of mechanical transmission 8 which kinematically link the slot 13 to an opening 5 through which a transmission rod activating key 6 is inserted.
  • the hole or opening 5 is made in a cover 10 of the door architrave, which covers the door motion means 1.
  • the hole 5 is preferably made in a central position in the cover 10 but in any case in a position such as to be standard for all types of door application, whether of the central-to-side opening type or of the telescopic type: thus it is possible to produce one sole type of cover 10 for all types of automatic lift doors.
  • the key 6 is inserted in a drum 7 internally anchored in the hole 5; a rotation of the key 6 causes a corresponding rotation of a pin 15 inserted in the drum 7 and connected by a wire 16 to a lever 17 privoted at 18 to the fixed frame 14.
  • the other end of the lever 17 supports a second pin 19 which strikes the support of the slot 13 causing said slot 13 to lower, with a consequent unlocking from the hook element 12, as shown in figures 2 and 4.
  • An elastic recall element (not illustrated), for example a spring, is provided to return the lever 17 to its original position when the key 6 is removed.
  • Figures 1 and 3 shows the carriage in the locked position, with the hook element 12 inserted in the slot 13.
  • the position is central for reasons of symmetry and to allow the key 6 always to act in traction on the wire 16.
  • the two pins 15 and 19, the wire 16 and the lever 17 constitute mechanical transmissions which kinematically connect the slot 13 to the hole 5.
