초록

A hold-open hinge mechanism for a molded plastic rainproof cover for a circuit breaker is disclosed. The hinge mechanism comprises an integrally molded pivot pin on the cover member and a hinge member on the cover base which pivotally engages the pivot pin. When the cover member is opened to a given angle, projections on the cover member engage the surface upon which the cover is mounted to releasably retain the cover member in the open position.
