Closure latch

Claim 2

A closure latch for latching a closure member to a support member, the closure member being swingably mounted for movement between open and closed positions relative to the support member, the closure latch mechanism including: striker means pivotally mounted on one of said members for movement from a locked position to an unlocked position; a latch member pivotally mounted on said other member for movement about a pivot axis between an unlatched position and a latched position, said latch member when moving from said unlatched position to said latched position being adapted to engage said striker means when said striker means is in said locked position to pull said members into a closed poSition relative to each other; lock control means connected to said striker means for moving said striker means between said locked position in which said striker means is positioned to be in operative relation to said latch member and said unlocked position in which said striker is in a position out of operative relation to said latch member; detent means positioned to normally engage and hold said latch member in said unlatched position and to be engaged by said striker means when said striker means is in said locked position to release said latch member; and actuator means connected to said latch member and connectable to a source of intermittent power for moving said latch member between said unlatched position and latched position.

Claim 3

A closure latch according to claim 1 wherein said lock control means includes: bias means operatively connected to said striker means to normally bias said striker means to said locked position; and key cylinder lock operated cam means operatively connected to said striker means to selectively pivot said striker means to said unlocked position.

Claim 4

A closure latch according to claim 1 wherein said striker means includes: a rotatably supported striker roller, and wherein said striker means includes; a rotatably supported striker roller, and wherein said latch member includes; pulldown flange means positioned eccentrically of said pivot axis for engagement with said striker roller to force said striker means toward said pivot axis.

Claim 5

A closure mechanism for latching a closure member to a support member, the closure member being swingably mounted for movement between open and closed positions relative to the support member, the closure mechanism including: striker means; latch means; said striker means being pivotally mounted on one of said members for movement about an axis from a locked position to an unlocked position in relation to said latch means; biasing means connected to said striker means to normally bias said striker means to said locked position; key cylinder lock controlled cam means operatively connectable to said striker means to rotate said striker means to said unlocked position; said latch means being rotatably mounted on said other member for pivotal movement about an axis between an unlatched position and a latched position in a direction normal to the pivotal axis of said striker means, said latch means having eccentric flange means whereby as said latch means is moved from said unlatched position to said latched position said eccentric flange means engages said striker means when said striker means is in said locked position to move said members into a closed position relative to each other; biased detent means positioned to normally engage and hold said latch means in said unlatched position and to be engaged by said striker means when said striker means is in said locked position to release said latch means for pivotal movement; and actuator means connected to said latch means for moving said latch means between said unlatched position and said latched position.

Claim 6

A closure mechanism for latching a closure member to a support member, the closure member being swingably mounted for movement between open and closed positions relative to the support member, the closure mechanism including: striker means; latch means; said striker means being pivotally mounted on one of said members for movement about an axis from a locked position to an unlocked position in relation to said latch means; biasing means connected to said striker means to normally bias said striker means to said locked position; key cylinder lock controlled cam means operatively connectable to said striker means to rotate said striker means to said unlocked position; said latch means being rotatably mounted on said other member for pivotal movement about an axis between an unlatched position and a latched position in a direction normal to the pivotal axis of said striker means, said latch means having eccentric flange means whereby as said latch means is moved from said unlatched position to said latched position said eccentric flange means engages said striker means when said striker means is in said locked position to move said members into a closed position relative to each other; biased detent means positioned to normally engage and hold said latch means in said unlatched position and to be engaged by said striker means when said striker means is in said locked position to release said latch means for pivotal movement; and actuator means connected to said latch means for moving said latch means between said unlatched position and said latched position.

Claim 7

A closure mechanism according to claim 4 wherein said actuator means includes: bias means connected to said latch means to normally bias said latch means to said unlatched position; and means connected to said latch means and connectable to a source of intermittent power to pivot said latch means to said latched position when said biased detent means is disengaged from said latch means.

Claim 8

A closure latch for latching a closure member to a support member, the closure member being swingably mounted for movement between open and closed positions relative to the support member, the closure latch mechanism including: striker means pivotally mounted on said closure member for movement about an axis parallel to the axis of the swinging movement of said closure member from a locked position to an unlocked position; lock control means connected tO said striker means for selectively moving said striker means between said locked position and said unlocked position; latch means pivotally mounted on said support member for pivotal movement about an axis at right angles to the pivotal axis of said striker means from an unlatched position, to a latched position, said latch means when moving from said unlatched position to said latched position engaging said striker means when said striker means is in the said locked position to move said closure member into a closed position relative to the support member; biased detent means positioned to normally engage and hold said latch means in said unlatched position and to be engaged by said striker means when said striker means is in said locked position to release said latch means; bias means connected to said latch means to normally bias said latch means to said unlatched position; and means connected to said latch means and connectable to a source of intermittent power to pivot a said latch means to said latched position when said biased detent means is disengaged from said latch means.

Claim 9

A closure latch for latching a closure member to a support member, the closure member being swingably mounted for movement between open and closed positions relative to the support member, the closure latch mechanism including: striker means pivotally mounted on said closure member for movement about an axis parallel to the axis of the swinging movement of said closure member from a locked position to an unlocked position; lock control means connected tO said striker means for selectively moving said striker means between said locked position and said unlocked position; latch means pivotally mounted on said support member for pivotal movement about an axis at right angles to the pivotal axis of said striker means from an unlatched position, to a latched position, said latch means when moving from said unlatched position to said latched position engaging said striker means when said striker means is in the said locked position to move said closure member into a closed position relative to the support member; biased detent means positioned to normally engage and hold said latch means in said unlatched position and to be engaged by said striker means when said striker means is in said locked position to release said latch means; bias means connected to said latch means to normally bias said latch means to said unlatched position; and means connected to said latch means and connectable to a source of intermittent power to pivot a said latch means to said latched position when said biased detent means is disengaged from said latch means.
