Abstract
A closing and latching mechanism for a closure in which further rotation of an input shaft in a latching direction results in engagement of a release cam with a release cam follower and movement of a release slider which moves a pawl into a position in which a claw is free to move from a latched position to an unlatched position and the claw then moves towards the unlatched position under the action of a biasing spring.
Claims22
A closing and latching mechanism for a closure, said closing and latching mechanism comprising:
- a claw for engaging a striker fixed to the closure, the claw being rotatable between an unlatched position and a latched position and biased by a spring towards the unlatched position,
- a pawl mounted to pivot between a first position, in which it can engage the claw in the latched position and prevent movement of the claw into the unlatched position, and a second position, in which the claw is free to move from the latched position to the unlatched position,
- a rotatable input shaft carrying a first clinch cam which is operatively coupled to the claw, whereby rotation of the input shaft in one direction results in rotation of the claw into the latched position, the input shaft also carrying a release cam which cooperates with a release cam follower coupled to a release slider, the release slider being operatively coupled to the pawl, whereby further rotation of the input shaft in said one direction results in engagement of the release cam with the release cam follower and movement of the release slider which moves the pawl into the second position and the claw then moves towards the unlatched position under the action of the biasing spring, and
- wherein the first clinch cam is operatively coupled to the claw by a first clinch cam follower, which cooperates with the first clinch cam and is provided on a linearly movable clinch slider, the clinch slider being operatively coupled to a second clinch cam, which cooperates with a second clinch cam follower forming part of a pivotally mounted clinch lever, a further part of the clinch lever constituting a third clinch cam which cooperates with a third clinch cam follower constituted by a portion of the claw.

- a pawl mounted to pivot between a first position, in which it can engage the claw in the latched position and prevent movement of the claw into the unlatched position, and a second position, in which the claw is free to move from the latched position to the unlatched position,
- a rotatable input shaft carrying a first clinch cam which is operatively coupled to the claw, whereby rotation of the input shaft in one direction results in rotation of the claw into the latched position, the input shaft also carrying a release cam which cooperates with a release cam follower coupled to a release slider, the release slider being operatively coupled to the pawl, whereby further rotation of the input shaft in said one direction results in engagement of the release cam with the release cam follower and movement of the release slider which moves the pawl into the second position and the claw then moves towards the unlatched position under the action of the biasing spring, and
- wherein the operative coupling between the first clinch cam and the claw includes a clutch which is selectively operable to sever the operative coupling.

- a manual release lever which is operably coupled to the pawl and the operation of which results in movement of the pawl into the second position, and
- wherein the manual release lever is mounted to pivot about the same axis as the pawl and is arranged to engage the pawl and to rotate it from the first position into the second position when the manual release lever is operated.
