Abstract
A locking mechanism and closure assembly are provided including a housing, a latch rotatably mounted to the housing, a spring member for urging the latch from a first position toward a second position, and a control member mounted to the housing for selectively securing the latch against rotation from the first position toward the second position. The control member may be slidably mounted relative to the housing, and may selectively rotate the latch from the first position toward the second position upon failure of the spring member. The latch may be positionable in a third position between the first and second positions, and may have a recess for receiving a striker designed for holding the striker within the recess at some times and guiding the striker into or out of the recess at other times.
Claims30
A locking mechanism comprising:
- a housing;
- a pin;
- a latch rotatably mounted to the housing via the pin so as to rotate around a central axis of the pin and movable between a first position and a second position, the latch including a first groove disposed a first distance from the pin central axis and a second groove disposed a second distance from the pin central axis the second distance being greater than the first distance;
- a spring member for urging the latch from the first position toward the second position;
- and
- a control member having a first part extending from and slidably mounted to the housing, and a second part slidably mounted to the first part, the second part being urged in a first direction for engaging the latch and securing the latch against rotation from the first position toward the second position and being movable via the first part in a second direction opposite the first direction for allowing such rotation, the control member being positionable to engage the first groove when the latch is in the first position and being positionable to engage the second groove when the latch is in the second position.

A locking mechanism comprising:
- a housing;
- a latch rotatable mounted to the housing and movable between a first position and a second position;
- a spring member for urging the latch from the first position toward the second position;
- and
- a control member having a first part extending from and slidably mounted to the housing and a second part slidably mounted to the first part, the second part being urged in a first direction for engaging the latch and securing the latch against rotation from the first position toward the second position and being movable via the first part in a second direction opposite the first direction for allowing such rotation, wherein the control member first part includes a rod and the control member second part includes a first pin, the control member further including a bracket mounted to the rod, the first pin being mounted to the bracket.

Locking mechanism comprising:
- a housing;
- a latch rotatably mounted to the housing and movable between a first position and a second position, the latch defining an opening therethrough;
- a spring member for urging the latch from the first position toward the second position;
- and
- a control member slidably mounted to the housing for selectively securing the latch against rotation from the first position toward the second position, the latch including a camming surface disposed on a portion of the opening for engagement by the control member, movement of the control member causing the control member to engage the camming surface to thereby rotate the latch from the first position toward the second position.
