Patent ID: 7234329

Claim:
A lock system for releasably maintaining a movable closure element in one of two different positions for the movable closure element relative to a support for the movable closure element, the lock system comprising: a latching assembly having a first state and a second state, the latching assembly in the first state releasably engageable with a part on the support to thereby releasably maintain the movable closure element with which the lock system is associated in the one position, the latch assembly comprising a first element that is changed from a first position into a second position to thereby cause the latching assembly to be changed from the first state into the second state whereupon a movable closure element with which the lock system is associated can be moved from the one position into the other of the two different positions; and an actuating system for the latching assembly, the actuating system comprising a first actuating assembly that is changeable from a first state into a second state by movement of a part of the first actuating assembly in an operating path from one position into another position to thereby cause the first element to be changed from the first position into the second position, wherein the first actuating assembly comprises a push button actuator that is movable from a normal position into an actuated position to change the first actuating assembly from the first state into the second state, the actuating system further comprising a blocking assembly having a first state and a second state, the blocking assembly in the first state allowing the first actuating assembly to be changed from the first state into the second state, the blocking assembly in the second state blocking the operating path to prevent the part of the first actuating assembly from being changed from the one position into the another position and the push button actuator from being moved from the normal position into the actuated position and thereby the first actuating assembly from being changed from the first state into the second state.
