Cabinet security system

A cabinet security system comprising

• a magnetic external key,
• an internal key,
• 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.

A cabinet security system comprising

• an actuator housing formed to include a latch window opening into a latch chamber formed in the actuator housing,
• a latch mounted for pivotable movement relative to the actuator housing about a latch pivot axis between an extended position extending out of the latch chamber through the latch window and a retracted position lying in the latch chamber,
• a latch actuator including a linkage coupled to the actuator housing and to the latch for movement in the latch chamber between a first position associated with the extended position of the latch and a second position associated with the retracted position of the latch and an internal magnet arranged to lie in the latch chamber and coupled to the linkage to move therewith,
• a magnetic external key configured to provide means lying outside of the latch chamber for exposing the rocker magnet to a magnetic field to cause the linkage to move from the first position to the second position to move the latch from the extended position to the retracted position, and
• an internal key arranged to move in the latch chamber relative to the actuator housing between an inactive position disengaging the linkage to free the linkage for movement between the first and second positions so as to free the latch for movement between the extended and retracted positions and an active position engaging the linkage upon movement of the linkage to the second position to cause the linkage to remain in the second position and the latch to remain in the retracted position without using the magnetic external key to expose the rocker magnet in the latch actuator to a magnetic field.
