US 5,490,581 A · Surface mounted modular fixture for elevators

Abstract

An elevator fixture includes a base plate module with opposed bent ends for mounting on a wall surface, and a housing open at the rear side to receive the base plate module and detachably couple the housing to the base plate module. The housing is formed from a face plate module and a frame module. The face plate module has one or more apertures through which call buttons or other indicating devices extend. The frame module is formed from a plurality of frame portions which are cut to length from an extrusion to match the dimensions of the face plate module. The frame portions are releasably coupled together by tabs and setscrews to releasably retain the face plate. Thus, the fixture can be assembled by selecting from among a plurality of different base plate, face plate and frame modules. The base plate module can include a positioning indicator and a positioning aperture for locating the fixture relative to an existing wall recess and/or in accordance with regulations.

Dependent claims

A surface mounted fixture for elevators having at least one indicating device mounted therein to signal an operational state of an associated elevator comprising:

a generally planar face plate having edges and at least one aperture formed therein for receiving the indicating device;
a frame surrounding said edges of said face plate and releasably retaining said face plate, said frame and said face plate forming a box-like housing having side walls extending rearwardly from said face plate and an open rear side for facing toward a wall surface;
a generally planar base plate having upper and lower end edges and means for attachment to the wall surface, said base plate being sized for insertion into said open rear side of said housing;
and
means for detachably coupling said frame to said base plate at said open rear side of said housing whereby when said base plate is attached to the wall surface, said upper and lower end edges of said base plate extend into said open rear side of said housing, said means for detachably coupling releasably engages said upper and lower end edges of said base plate and said housing encloses and covers said base plate in cooperation with the wall surface.
