Abstract
An improved locking system for furniture of the type having a plurality of drawers, at least one of which is locked from a remote position through a keyed operator module by translating a slide bar to interfere with one of the drawers in a locked position. A flexible, rotatable cable extends between the operator module and a connector/actuator module associated with the slide bar. The connector/actuator module comprises a crank with an integral shaft and rotatable, eccentric lug which is directed in an L-shaped slot in a slide plate. Rotation of the cable imparts translatory movement to the slide plate which is followed by the slide bar. In another aspect of the invention, the operator module, which is geared to the cable through a translatable rack, causes extension of a bolt on the rack to lock a second drawer simultaneously as the slide bar realizes a locked position. The modular construction of the connector/actuator and operator permits separate manufacture and assembly after which the cable can be operatively engaged with each.
