  • Patent number: 9517363
    Abstract: A handheld forcible entry device includes a tubular housing. An 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 bevel gear set. 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.
