Patent ID: 7849720

Claim:
A lock comprising: an outer housing; a compression spring; a push button housing; a locking pin configured to receive a force from the compression spring along a first axis; a cam pin configured to engage the locking pin and to be movable along a second axis, the second axis being substantially perpendicular to the first axis; a cam pin spring configured to provide a force to the cam pin in a first direction along the second axis; and a cam configured to rotate between a locked position and an unlocked position with respect to the first axis and selectively engage the cam pin, the cam comprising: an eccentric pin protruding from a circular end surface of the cam and configured to move the cam pin in a second direction along the second axis when the cam rotates from the locked position, the second direction being opposite to the first direction; and an elastic cam pin stop extending from the circular end surface of the cam and configured to prevent the cam pin from substantially moving in the second direction along the second axis when the cam is in the locked position, wherein the eccentric pin is configured not to provide a force to the cam pin in the first direction along the second axis when the cam rotates from the unlocked position to the locked position, wherein the elastic cam pin stop is a spring comprising: a first end connected to the circular end surface of the cam; a second end; and a body portion extending between the first end and the second end.
