Abstract
In an electrical switchboard vertical section, vertically adjacent pairs of cubicle doors are mounted by common hinge blocks located adjacent door corners and releaseably, latchingly retained in their closed positions by common latch blocks located adjacent opposed door corners. Horizontally aligned pairs of hinge and latch blocks additionally serve as mounts for instrument compartments located in the spaces available between vertically adjacent doors; these compartments slidingly accomodating drawout instrument drawers.
Claims9
In an electrical switchboard vertical section comprising a vertical array of cubicles accommodating electrical equipment;
- the arrangement including, in combination:
- a plurality of doors, one for each cubicle;
- upper and lower hinge pins assembled to each said door in vertical alignment adjacent corresponding upper and lower corners thereof;
- upper and lower hinge blocks for each cubicle assembled to the switchboard in vertical alignment, each said hinge block including a pair of vertically aligned upwardly and downwardly opening sockets for accommodating said hinge pins, adjacent upper and lower hinge pins of each vertically adjacent pair of said doors being received in said downwardly opening and upwardly opening sockets, respectively, of one of said hinge blocks, whereby to mount said doors for swinging movement between open and closed positions;
- a latch assembly mounted to each said door, each said assembly including a pair of vertically aligned upwardly and downwardly extending latch rods having terminations respectively projectable beyond upper and lower door edges, and a manual operator for selectively retracting said latch rod pair;
- a plurality of latch blocks assembled to the switchboard in common vertical alignment and respective, individual alignment with each said hinge block, each said latch block including a pair of vertically aligned upwardly and downwardly opening notches, adjacent upwardly and downwardly extending latch rod terminations of each vertically adjacent pair of said doors being respectively, retractably received in said downwardly and upwardly opening notches of one of said blocks, whereby to releasably latch said doors in their closed positions;
- and
- partition members mounted by at least one horizontally aligned pair of said hinge and latch blocks to define an instrument compartment at a location intermediate vertically adjacent doors.
