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.
摘要翻译：电梯轿厢组件（14）包括在平台组件（34）下方具有水平板梁（36）的框架（28）。多个支架（44）相对于框架支撑平台组件（34）。支架（44）包括与紧固件（58,60）相关联的至少一个狭槽，以便于相对于框架调节平台组件（34）的位置。调整平台组件（34）的位置允许以不需要引入重量或其他昂贵的平衡措施的经济方式使轿厢框架组件平整。

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.
