  • Patent number: 4226451
    Abstract: This latch is meant to provide safety against unintended actuation, in particular by a child, and is characterized by requiring a relatively unnatural combination of pushing and rotation to be actuated. More particularly, the rotation must be done while the knob or handle is held in pushed position against a spring bias. This safety latch includes a latch housing, a slidable bolt having a wedge shape outer end portion selectively retractable in the latch housing, a cam rotatably engaging the bolt and operatively retracting the latter, a stem extending endwise into the latch housing, axially pushable inward, and operatively rotating the cam for retraction of the bolt by the cam upon rotation of the stem while the latter is held inwardly pushed.
