ABSTRACT:
Disclosed is a device for anchoring a movable box-shaped shelf assembly of the type wherein the assembly is supported by wheels which in turn ride on parallel rails laid on a floor and a handwheel is attached to one side wall of the assembly and is drivingly coupled through a reduction gear to a shaft of the wheels so that upon rotation of the handwheel, the shelf assembly may be moved along the rails in either direction. The anchoring device comprises a toothed locking wheel carried by a shaft of the handwheel for rotation therewith, an operating member which has its lower end terminated into a locking pawl and is disposed for vertical movement so that the locking pawl may drop into a space between teeth of the toothed locking wheel by its own weight, and a locking knob having its shaft extended through the side wall, the inner end of the shaft terminated into a wedge which is slidably fitted into a guide opening formed through the operating member with the hypotenuse surface of the wedge made into slidable contact with the upper end of the guide opening so that the reciprocal slidable movement of the wedge in the direction perpendicular to the axis of the operating member causes the reciprocal vertical movement of the latter and when the operating member is lowered, its locking pawl engages with the teeth of the toothed locking wheel to lock it securely against rotation and consequently the shelf assembly may be securely anchored at rest on the rails.
