A dual cam lock apparatus for a locking blade. The apparatus comprises a rotatable lock comprising a cam shaft, a first cam and a second cam. The first cam comprises a first cam body rotationally coupled with the cam shaft, at least one protrusion upstanding from a surface of the first cam body, and a first arm extending from the first cam body configured to contact the locking blade to retain the locking blade in the locking position. The first cam is rotatable by the cam shaft to move the first arm in and out of contact with the locking blade. The second cam comprises a second cam body with at least one slot therethrough which receives the at least one protrusion, and a second arm extending from the second cam body and coupled with the locking blade. The slot has an angular span across which the protrusion rotates before further rotation of the protrusion causes rotation of the second cam, whereby rotation of the second cam rotates the second arm to move the locking blade between the locking and release position. The locking blade can be used to releasably lock a housing, such as a cabinet, drawer, chest or the like. |
