摘要:
An improved device for locking the floor door of lifts, applied to a pair of doors or panels (10-12) of a floor door, sliding along an upper track (14) through respective slides (18-20) and along a lower threshold (16), comprises a primary keyhole (24), fixed to the crosspiece (22) of said floor door, whereto a pivoting lock (26) is connected, provided with a bolt (28) engaged with the primary keyhole (24) and the secondary keyhole (30); said device comprises a second bolt (32), placed at or in the proximity of, the lower end of the floor door and fixed inside one of said doors (10) or (12). The second bolt is articulated on a support (34) and pivots along a plane parallel to the plane that identifies the inside and/or outside surface of the same doors hooking the opposite door (10) or (12) to the fitting bolt (32) in a slit made into the door.

摘要:
A safety device for lift doors and sliding doors or shutters in general, electrically powered, specially suited to avoid the danger of having one's fingers being caught in between the lift doors (12-14) and the respective jambs (10) or between the two doors while the latter are opening, of telescopic or central opening type, with glass or crystal (16) with a frame (18) or of a different type, includes at least one electrosensitive strip (20) with middle edge (26) orthogonally developed from the base, vertically extended on at least one of the jambs (10) and/or doors (12) and/or (14) and electrically wired to the cage door control board or to the lift system control board or indirectly connected to e.g. an infrared transmission system.
摘要:
An active slide (10) for doors of lifts' cabins, comprising a linearly developing blade, vertically oriented, featuring respective ends folded according to the same angle, connected in an articulated manner with a carriage (12) connected to a driving engine by means of a cogged belt (14) and a lever (16) through elastic means (20), said slide cooperating with a balancing hook (18) and an unlock lever (22); the unlock lever (22) is operatively connected to electrically activating means (24) provided with a cam (26) or the like for striking the free end of the lever itself.
摘要:
A drive unit for doors, especially doors having a non-rectilinear profile formed by wings (26, 26', 24, 24', 124, 126) comprises a motor (10) whose rotary shaft (20) engages with at least a bar or section (12, 14) connected to at least one of said wings. Said drive unit is located either on the roof or the external front of the lower basis or between the wings of an elevator car of story doors. In case of telescopic movement superposed wings, one of the wing is moved by the drive unit, and a transmission unit (100) transmits the rotation of a wing (124) to the other one (126).
