A handheld forcible entry device includes a tubular housing. A torque-input drive shaft is rotationally assembled to the housing, wherein the input shaft rotates about an axis perpendicular to a longitudinal axis of the housing. A helical pressure applicating lead screw is rotationally assembled to the housing, wherein the lead screw rotates about an axis parallel to the housing longitudinal axis. The input shaft and lead screw are rotationally synchronized by a gear assembly. A pressure applicator is threadably engaged with a helical threaded segment integrated in the lead screw. Rotation of the threading advances or retracts the pressure applicator from a stationary wedge plate. The separation of the pressure applicator and the stationary wedge plate separates a locked member from the associated frame, thus forcibly opening the locked member. The input shaft can be operated using a manually applied rotation or power applied rotation.

Powered hand-held forcible entry device

A mechanical hand held door opener device, light in weight and operable in any orientation including being inverted, for generating substantial door-opening force with a minimum effort from a user. When the user rotates the handle, he or she activates the unit by moving the shaft that interlocks with the first and second bevel gears. Since the second gear is fastened to the central lead screw, its rotation causes the rotation of the screw. The rotation of the screw then advances or retracts, depending on the clockwise or anti-clockwise rotation; and the inner platform and the four columns attached to the inner platform moves inwardly or outwardly of the outer platform.

Power operated hand-held forcible entry device

An integrally molded glide cover has a top and a base that interlock together to surround and encapsulate the lower portion of an existing furniture glide. A rim protrudes downwardly from the bottom of the base and surrounds a recessed bottom surface for receiving an insert that is adapted for sliding on floors without damaging the floor surface. A hinge allows the base to close over the bottom of the glide and into direct alignment with locking prongs on the top for interlocked attachment of the base to the top using one hand and no tools. When interlocked, the top and base provide a tamper-proof permanent attachment that presents a low profile appearance closely resembling the exterior configuration of the encapsulated lower glide portion.
