Abstract
A dual cam lock apparatus comprising a locking blade, a rotatable lock, a first cam and a second cam. The first cam comprises a first cam body and a first arm extending from the first cam body. The first cam is rotatable by the rotatable lock 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 at least one protrusion of the first cam, 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.
Claims29
A dual cam lock apparatus comprising:
- a locking blade movable between a locking and release position;
- a rotatable lock comprising a cam shaft;
- a first cam comprising 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, wherein the first cam is rotatable by the cam shaft to move the first arm in and out of contact with the locking blade;
- and
- a second cam comprising 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, wherein the at least one slot has an angular span across which the at least one protrusion rotates before further rotation of the at least one 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.
A dual cam lock comprising:
- a rotatable lock comprising a cam shaft;
- a first cam comprising 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 wherein a portion of the first arm is longitudinally extended and extends beyond an outer edge of the first cam body with a gap between the longitudinally extended portion of the first arm and the first cam body, wherein the first cam is rotatable by the cam shaft between a lock and unlock position;
- and
- a second cam comprising 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, wherein the at least one slot has an angular span across which the at least one protrusion rotates before further rotation of the at least one protrusion causes rotation of the second cam.
