Abstract
A portable, hand-held forcible entry device is provided for opening locked or barricaded doors in emergency situations. The device comprises a firearm secured to a hollow cylindrical housing. A piston is positioned in a chamber in the housing and drives a striker. An interchangeable tool bit is mounted to the striker. When the firearm is fired, the percussive force causes the piston to move forward in the interior chamber toward the striker. The piston strikes the base of the striker causing the tool bit mounted on the striker to forcibly move forward into a target object, such as a locked or barricaded door. Compression springs are positioned in the chamber to return the piston to the firing position. The device is particularly suitable for use by law enforcement and emergency personnel for forcing locked doors open and for freeing victims trapped in automobile accidents. The device is adaptable to virtually any type of personal firearm, and may incorporate additional features, such as supplemental illumination means and a ferrous metal detector to assist in positioning the device.
