Abstract (en)
[origin: US4620735A] A door-bolting device for electrical appliances, in particular washing machines, comprises a longitudinally displaceable slide bolt having a locking opening for a door-locking hook, one or two bolting openings for engagement by a bolting rod, and a lock-down recess. In open position, the free end of a signal contact spring enters this lock-down recess; this spring and a fixed contactor member opposite and parallel with the former constitute a signal contact unit. During bolting operation, a signal contact is made in this unit and controls a bolt-actuating relay comprising a magnet yoke, a coil, a core and a double-armed magnet armature lever. The free end of a bolting arm of the latter constitutes a bearing for the bolting rod which is displaced, during bolting operation, by a swivel motion of the lever. The end of a main contact arm of the same lever serves as bearing for a connecting shaft which is fastened to a diaphragm subdividing a pressure chamber. The latter is connected with a pressure-equalizing chamber fillable with a fluid medium such as water via a supply duct. The connecting shaft end remote from the diaphragm exerts during bolting displacement increasing pressure on a main contactor spring which makes, together with a fixed main contactor member, a main contact for switching on the appliance.
