A latching system including a latch assembly, a cup, and a keeper plate. The latch assembly includes a base, a lever, and a catch. The lever is pivotally connected to the base and the catch is pivotally connected to the lever. The base is pivotally attached to the cup such that it rotates about an axis of rotation that is perpendicular in direction in relation to the direction of the axis of rotation of the lever relative to the base. The keeper plate includes a keeper projection. The lever can be lifted and the latch assembly rotated about the axis of rotation of the base to clear the keeper from the catch and thereby allow the opening of a first closure member relative to a second closure member.

The invention claimed is: 1. An over-center draw latch for securing a first closure member in a closed position relative to a second closure member, the second closure member being provided with a keeper, the latch comprising: a base; a lever pivotally connected to said base, said lever being pivotally movable relative to said base about a first axis of rotation; a catch pivotally connected to said lever, said catch being pivotally movable relative to said lever about a second axis of rotation, said second axis of rotation being parallel to said first axis of rotation, said catch being adapted for engaging the keeper to secure the second closure member in the closed position relative to the first closure member when the latch is in a latched configuration and said base is mounted to the first closure member; and a spring, wherein said catch and said lever are biased by said spring toward respective positions corresponding to said latched configuration, wherein said base is adapted for being pivotally mounted to the first closure member such that said base is pivotally movable about a third axis of rotation that is perpendicular in direction to said first axis of rotation, and wherein said catch can clear the keeper when, with the latch initially in said latched configuration, said lever is lifted and the latch rotated about said third axis of rotation. 2. An over-center draw latch system for securing a first closure member in a closed position relative to a second closure member, the latch system comprising: a keeper adapted for attachment to the second closure member; and a latch comprising: a base; a lever pivotally connected to said base, said lever being pivotally movable relative to said base about a first axis of rotation; a catch pivotally connected to said lever, said catch being pivotally movable relative to said lever about a second axis of rotation, said second axis of rotation being parallel to said first axis of rotation, said catch being adapted for engaging said keeper to secure the second closure member in the closed position relative to the first closure member when the latch is in a latched configuration and said base is mounted to the first closure member; and a spring, wherein said catch and said lever are biased by said spring toward respective positions corresponding to said latched configuration, wherein said base is adapted for being pivotally mounted to the first closure member such that said base is pivotally movable about a third axis of rotation that is perpendicular in direction to said first axis of rotation, and wherein said catch can clear said keeper when, with the latch initially in said latched configuration, said lever is lifted and the latch rotated about said third axis of rotation in order to allow the opening of the first closure member relative to the second closure member. 3. The over-center draw latch system according to claim 2, wherein said keeper is part of a keeper plate, wherein said keeper plate is provided with a raised platform opposite said keeper, and wherein said raised platform limits the movement of said catch away from said keeper as said lever is lifted such that the latch must be rotated for said catch to clear said keeper. 4. The over-center draw latch system according to claim 3, wherein said lever is provided with two arms that are positioned on either side of said base, and wherein said catch is provided with two arms that are positioned on either side of said lever. 5. The over-center draw latch system according to claim 3, wherein said catch is provided with a tongue that covers said base when said latch is in said latched configuration. 6. The over-center draw latch system according to claim 5, wherein said lever is provided with two arms that are positioned on either side of said base, and wherein said catch is provided with two arms that are positioned on either side of said lever. 7. The over-center draw latch system according to claim 2, wherein said catch is provided with a tongue that covers said base when said latch is in said latched configuration. 8. The over-center draw latch system according to claim 7, wherein said lever is provided with two arms that are positioned on either side of said base, and wherein said catch is provided with two arms that are positioned on either side of said lever. 9. The over-center draw latch system according to claim 2, wherein said lever is provided with two arms that are positioned on either side of said base, and wherein said catch is provided with two arms that are positioned on either side of said lever.
