Abstract

A bimetallic strip or plate member has a curvature at a first temperature and a second curvature at a second, higher, temperature. The bimetallic member is heated when the door is closed and electric current is supplied to the device. A locking member, operatively coupled to the bimetallic member is arranged for rotational motion between a free position in which the door can be opened and a locking position in which it is locked. When current is supplied to the heating device, the temperature of the bimetallic member is increased so that the member trips into its second curvature state, thus causing the locking member to rotate to its locking position. When current is no longer supplied to the heating device, the member cools and trips back to its first curvature state, after an interval, thus causing or allowing the locking member to rotate to its free position.
