Abstract:
A lock system for an appliance providing multiple detection switches (24, 30, 31) for lid closure and lid locking encodes the switch states as different voltages on a single signal line (42) to reduce wiring harness costs.
Abstract:
A transportation-robust bi-stable latch mechanism preserves low actuation forces by means of an auxiliary mechanism blocking the effects of shock forces during transportation.
Abstract:
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.
Abstract:
A lock (16) for a washing machine or the like provides fast actuation through a solenoid driven bolt (32) that remains stably in the locked position after power is no longer applied to the solenoid (38). The possibility of power failure preventing subsequent access to the washing machine is avoided through the use of a slower actuation time, thermal actuator (59) storing sufficient energy to unlock the bolt after a time delay when power is lost.
Abstract:
A printed circuit board (10) provides lateral notches (22) for receiving wire conductors (30) in a lateral direction to be joined with printed circuit board traces by solder or an insulation displacement connector eliminating the need for laborious sequential insertion of conductors through printed circuit board holes.
Abstract:
A latch for an appliance or the like provides a floating bolt assembly spring biasing a door against a sealing gasket in different positions depending on gasket compliance. A lock provides a stop that may adjustably bridge a distance between the latch frame and the floating bolt assembly as the gasket ages thereby providing positive locking of the door over the life of the appliance.
