Abstract

A latch assembly for releasably securing a closure element with a striker element in a closed position. The latch assembly consists of a housing with a body, a release lever mounted for movement relative to the housing between (a) a normal position and (b) a release position; first and second latch elements mounted to the housing for movement relative to each other and the housing, with the first latch element being movable relative to the housing between a latched position in which it maintains the closure in its closed position and a release position in which the closure can be moved out of its closed position, and cooperating structure on the release lever and first and second latch elements for moving the second latch element relative to the housing and, in response thereto, causing the first latch element to move from its latched position to its release position as an incident of the release lever moving from its normal position to its release position.

Dependent claims

A latch assembly for releasably securing a closure element having a striker element in a closed position, said latch assembly comprising:

a housing with a body;
a release lever;
means for mounting the release lever for movement relative to the housing between (a) a normal position and (b) a release position;
first and second latch elements,
said first latch element having a hooked end portion for engaging the striker element for maintaining the closure element in its closed position;
means for mounting the first and second latch elements to the housing for movement relative to each other and the housing,
said first latch element being movable relative to the housing between (a) a latched position in which it maintains the closure in its closed position and (b) a release position in which the closure can be moved out of its closed position,
there being cooperating means on the release lever and first and second latch elements for moving the second latch element relative to the housing and, in response thereto, causing the first latch element to move from its latched position to its release position as an incident of the release lever moving from its normal position to its release position;
a locking arm;
and
means for mounting the locking arm to the housing for movement relative to the housing between (a) a locked position and (b) an unlocked position,
there being cooperating means on the locking arm and second latch element for blocking movement of the second latch element relative to the housing with the locking arm in its locked position to thereby prevent movement of the first latch element from its latched position to its release position through the release lever,
said first element being movable from its latched position to its release position with the locking arm situated to block movement of the second latch element from its first position.

A latch assembly for releasably securing a closure element having a striker element in a closed position, said latch assembly comprising:

a housing with a body;
a release lever;
means for mounting the release lever for movement relative to the housing between (a) a normal position and (b) a release position;
first and second latch elements,
said first latch element having means for engaging the striker element for maintaining the closure element in its closed position;
and
means for mounting the first and second latch elements to the housing for movement relative to each other and the housing,
said first latch element being movable relative to the housing between (a) a latched position in which it maintains the closure in its closed position and (b) a release position in which the closure can be moved out of its closed position,
there being cooperating means on the release lever and first and second latch elements for moving the second latch element relative to the housing and, in response thereto, causing the first latch element to move from its latched position to its release position as an incident of the release lever moving from its normal position to its release position,
wherein said cooperating means includes a shoulder on each of the first and second latch elements, said shoulder on the second latch element engaging the shoulder on the first latch element to move the first latch element from its latched position to its release position as the release lever is moved from its normal position to its open position;
a closure that is movable between open and closed positions and carrying said striker element, wherein the first latch element has a cam surface which cooperates with the striker element, said striker element progressively urging the first latch element from its latched position towards its release position as an incident of the closure moving from its open to its closed position;
and
a movable locking arm for selectively blocking movement of the second latch element,
wherein with the locking arm situated to block movement of the second latch element from its first position, the first latch element is movable from its latched position to its release position.

A latch assembly for releasably securing a closure element having a striker element in a closed position, said latch assembly comprising:

a housing;
a release lever;
means for mounting the release lever for movement relative to the housing between (a) a normal position and (b) a release position;
first and second latch elements,
said first latch element having a hooked end portion for engaging the striker element for maintaining the closure element in its closed position;
and
means for mounting the first and second latch elements to the housing for movement relative to each other and the housing,
said first latch element being movable relative to the housing between (a) a latched position in which it maintains the closure in its closed position and (b) a release position in which the closure can be moved out of its closed position,
there being cooperating means on the release lever and first and second latch elements for causing the release lever to act directly against the second latch element to move the second latch element from a first position to a second position as the release lever moves from its normal position into its release position and for causing the second latch element to act directly against the first latch element and move the first latch element from its latched position into its release position as the second latch element moves from its first position to its second position,
wherein the cooperating means includes means for allowing the first latch element to move from its latched position to its release position without moving the second latch element from its second position to its first position.
