Abstract

See full text

An appliance latch provides a hook that may be energized against a spring force to receive a catch element which releases the hook to pull the catch element into engagement. A toggle arm may be used to hold the hook in the energized state before receipt of the catch element to provide for a sensitive and predictable release of the spring force with rotation of the hook. The hook may be mounted on a floating pivot both to accommodate the toggle arm operation and to permit re-engagement of the catch element with the hook in the event that the hook is released from its energized state without engagement of the catch element, for example, by inertial forces.
