Abstract
In a locking arrangement of an electric circuit breaker which includes a latch and a locking strap which cooperates with the latter and is supported by means of two pivots in support openings of stationary parts, the pivots having a rectangular cross-section and arranged so that the force exerted by the latch on the locking strap is transmitted to one of the small surfaces of the pivots, the support openings have a convex surface which cooperates with the one small surface of the pivot and the long surfaces of the pivots are opposite similarly convex surfaces of the support openings. For the other small surface of the pivots, a concave surface or a surface which consists of two subsurfaces which are at an angle to each other and are connected by a transition arc is provided. The pivots cooperate with the support openings by rolling and sliding motions which insure low stress on the contact surfaces.
