ABSTRACT:
A draw pull latch for securing two members together comprises a keeper affixed to one of the members and a second one-piece part which is composed of three segments; i.e., a base segment, an intermediate segment, and a locking segment. The base segment is adapted for being affixed to the second one of the members and the intermediate segment is flexibly connected to the base segment and the locking segment for pivotal movement of the segments about transverse axes. When in the locked condition, the intermediate segment is disposed in substantially coplanar relation to the base segment, and the locking segment is disposed in overlying relation to the base segment and the intermediate segment and to the keeper. The locking segment is detachably connected to the keeper, and the flexible connection between the intermediate and locking segments is closer to the second member than the flexible connection between the intermediate and base segments. The base segment has recesses in the sides thereof which mate with lugs in the cavity of the locking segment. A secondary locking feature is provided by use of an angular catch member disposed between the one-piece part and the second member and having a leg portion extending through the locking segment whereby the locking segment is retained in the latched condition. A finger notch is provided on the locking segment which, along with the outwardly extending edge of the catch member facilitates the opening of the latch, when desired.
