Abstract
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.
Claims17
A cover comprising:
- a cover base adapted to be mounted to a mounting surface;
- a cover member having a closed position and a hold-open position;
- hinge means connecting the cover member to the cover base for pivoting the cover member relative to the cover base, said hinge means comprising a pivot member on the cover member and a hinge member on the cover base;
- and
- at least one projection means on the cover member and engagable with the mounting surface for releasably retaining the cover member in its hold-open position.
A rainproof hold-open cover for a circuit breaker adapted to be mounted in an electrical panel comprising a cover base, means for fastening the cover base to the electrical panel, a U-shaped hinge member connected to said cover base by a resilient neck member, a cover member having a cylindrical pivot member, said U-shaped hinge member rotatably engaging over said pivot member, at least one projection means on said cover member adjacent an end of the pivot member for releasably retaining the cover member in the open position, said projection means being engagable with the surface of the electrical panel when said cover member is rotated to an open position.
