ABSTRACT:
A locking system defined between a stationary support housing defining an interior space to be closed by a closure, and a closure movably mounted upon the stationary support housing between an open, unlocked position and a closed, locked position, includes first and second cams fixedly mounted upon the closure, and a rotatable control element rotatably mounted upon the stationary support housing. When the closure (10) is disposed in its closed, locked position within the stationary support housing (11), the first cam (32) is engaged with a first end (27) of the rotatable control element (25). In order to move the closure (10) to its open, unlocked position, the closure (10) is initially pivoted inwardly of the housing (11) such that the first cam (32) is disengaged from the first end (27) of the control element (25) and the second cam (31) engages a second end portion (29) of the control element (25) so as to initially rotate the control element out of its initial angular orientation at which the control element (25) cooperates with the first cam (32) in the locked position. Pivoted movement of the closure (10) toward the open, unlocked position causes the first cam (32) to rotate the control element (25) further toward a second angular orientation as the first cam (32) passes by the control element (25) as the closure (10) achieves the open, unlocked position. Pivoted movement of the closure (10) back toward its closed, locked position causes the second cam (31) to engage the first end portion of the control element (25) as the closure (10) is pivoted inwardly of the housing (11) beyond the closed, locked position so as to rotate the control element (25) to its second angular orientation. Release of the closure (10) so as to permit the same to pivot a predetermined amount back outwardly toward the open, unlocked position causes engagement of the first cam (32) with a second end (28) of the control element (25) whereby the closure (10) is again disposed at its closed, locked position.
