Patent ID: 8397546

Claim:
A cabinet security system comprising a latch blocker adapted to be coupled to a frame included in a cabinet and formed to include an aperture opening into an interior region formed in the cabinet, a magnetic external key separated from the cabinet and adapted to mate with an exterior wall of a panel included in the cabinet and mounted for movement relative to the frame to open and close the aperture formed in the frame, and a panel motion controller adapted to be mounted on an opposite interior wall of the panel to lie in the interior region of the cabinet when the panel is closed, wherein the panel motion controller comprises an actuator housing formed to include a latch window opening into a latch chamber formed in the actuator housing, a panel lock including a latch mounted for pivotable movement relative to the actuator housing about a latch pivot axis between an extended position extending through the latch window to lie in confronting relation to the latch blocker when the panel is closed and a retracted position lying in the latch chamber to disengage the latch blocker to free the panel for movement relative to the frame to an opened position, and a latch actuator located in the latch chamber and configured to provide means for moving the latch from the extended position to the retracted position in response to exposure to a magnetic field produced by the magnetic external key when the magnetic external key is mated with the exterior wall of the panel, the latch actuator including a rocker mounted for pivotable movement relative to the actuator housing about a rocker pivot axis between a panel-locking position associated with placement of the latch in the extended position and a panel-unlocking position associated with placement of the latch in the retracted position, a motion-transfer link pivotably coupled at a first end thereof to the rocker to establish a first link pivot axis and at a second end thereof to the latch to establish a second link pivot axis, and an internal magnet coupled to the rocker to move therewith and arranged to lie in spaced-apart relation to the first end of the motion-transfer link to locate the rocker pivot axis therebetween and to lie in the magnetic field produced by the magnetic external key when the magnetic external key is mated with the exterior wall of the panel and to be drawn magnetically toward the interior wall of the panel and the magnetic external key on the exterior wall of the panel to cause relative pivoting movement of each of the rocker, motion-transfer link, and latch to move the latch from the extended position to the retracted position.
