ABSTRACT:
A modular elevator control housing with an easily accessibly interior is disclosed. The housing comprises a generally rectangular, elongated casing that is conveniently placed on a wall adjacent to an elevator. The housing protectively encloses elevator operational controls. The housing may replace an existing control housing, mounting over the existing elevator outlet and using existing holes. Alternatively, the housing may be originally installed during building construction. The housing comprises a chassis covered by a display. The chassis comprises a subframe that secures the housing to the wall and a top and bottom cover. The subframe comprises a base bounded by integral, projecting side flanges. Chassis sidewalls are secured to the subframe sides. The inner surfaces of the sidewalls define multiple, parallel channels. Two of the channels seat fasteners to secure the top and bottom covers to the sidewalls. One of the channels captivates fasteners that secure the sidewalls to the subframe. The remaining, sliding channel receives the display components. Interior brackets secured to the subframe cooperate with the sliding channel to support the display in a desired configuration. The display comprises faceplates separated by mating clips. Faceplate numbers may be varied during installation. Mating clips join abutting plates. The interior of the housing may be easily serviced by selectively removing the top or bottom cover and sliding out the faceplates.
