摘要： A sound absorbing light fixture (42) installed in a surface system, such as an elevator ceiling system (40), of an enclosed interior, such as the interior (32) of an elevator cab (32) is presented. The light fixture (42) comprises a frame (46) disposed in fixed relationship to the surface system, the frame (46) having an interior rear surface and interior side surfaces extending outwardly from the rear surface to define a cavity (50). A light source (48) is supported by the frame (46) within the cavity (50). Additionally, a light diffuser (44) is disposed in fixed relationship to a front portion of the frame (46) between the light source (48) and the enclosed interior. The installed light fixture (42) enhances a sound absorption coefficient, e.g., above 0.6, of the surface system for a predetermined frequency range of sound energy, e.g., 300-600 Hz.

摘要： An elevator car assembly (14) includes a frame (28) having a horizontal plank beam (36) beneath a platform assembly (34). A plurality of braces (44) support the platform assembly (34) relative to the frame. The braces (44) include at least one slot associated with a fastener (58, 60) to facilitate adjusting a position of the platform assembly (34) relative to the frame. Adjusting the position of the platform assembly (34) allows for leveling the car frame assembly in an economical manner that does not require the introduction of weights or other expensive balancing measures.

摘要： An elevator load bearing assembly includes a plurality of cords within a jacket. The jacket has a plurality of grooves spaced along the length of the belt assembly. In one example, the grooves are separated by varying spacings along the length of the belt. In another example, at least a portion of each groove is aligned at an oblique angle relative to the longitudinal axis of the belt. Another example includes a combination of the different spacings and the non-perpendicular alignment.
