  • Patent number: 7201411
    Abstract: A push latch that may be used in automobile applications to open and close compartment doors or bins reduces the number of components typically found in prior art designs while retaining the same quality and function. The push latch of the invention further eliminates the use of metal pins and springs, provides an assembly that is easier to assemble and reduces the cost to manufacture. In one embodiment, the push latch generally includes the use of a housing, lock and button. The lock includes the use of a flexible spring arm and bosses, which will engage with cam slots in the button. In operation, when the button is pushed, the cam slots will force the bosses and the lock downward causing the release of the compartment door. When the button is released, the flexible spring arm forces the cylindrical bosses upward in the cam slots thus forcing the button and lock back to their original positions.
