Abstract

A coupling and locking assembly for synchronous doors of elevator equipment. The assembly includes a coupling and locking device mounted to a guide element by a fastening system having a plurality of holes spaced from each other. The coupling and locking device includes a base plate, a pair of coupling blades and a pair of rotating articulated levers. Movable pins integral with the articulated levers are configured to fit into slots in the coupling blades. At least one part of the slots is provided with teeth which extend inside the respective slot such that the slot has a sawtooth shape to define a plurality of discrete seats into which respective movable pins may be introduced, thereby providing the coupling blades with a corresponding plurality of different mounting configurations relative to the articulated levers. The coupling blades and the articulated levers may be constructed according to one of three different profiles.

Abstract

A coupling and locking device for synchronous doors of an elevator. The device includes a pair of coupling blades movable on a base plate, a pair of rotating levers hinged to the coupling blades to form a parallelogram mechanism, and a hooking lever movable to engage a fixed component of the elevator. The hooking lever is connected to a first rotating lever by a rotor mechanism having a primary rotor rotatable around a fixed pin on the base plate, and a secondary rotor with a first connecting pin for connection to the first rotating lever and a second connecting pin for connection to the primary rotor. A third connecting pin connects the hooking lever with the secondary rotor such that movement of the coupling blades causes a rotation of the hooking lever. The secondary rotor has an arc-shaped slot, within which the third connecting pin is inserted.
