    • A collapsible steering column assembly preferably has a collapsible steering shaft that extends rotatably along a centerline and a collapsible column that houses and co-extends with the shaft. The column preferably has inner and outer jackets that retract axially to collapse the column. An energy absorbing device has a member engaged between the inner and outer jackets and controls the collapse of the column generally via a high load stage and a low load stage of operation. The member is preferably elongated axially having a distal end that is looped over and spaced radially outward from the remainder of the member. The distal end is attached disengagably to the outer jacket via a pin received in a hole in the distal end and a fuse engaged operably to the pin and attached to the outer jacket.
    • 可折叠的转向柱组件优选地具有可折叠的转向轴,其可沿着中心线可旋转地延伸,并且可收缩的柱与轴接合并共同延伸。 该柱优选具有轴向缩回以使柱收缩的内外套。 能量吸收装置具有接合在内外套之间的构件,并且通常经由高负载阶段和低负载阶段来控制塔的塌缩。 优选地,该构件在轴向上是细长的,其远端与构件的其余部分环绕并且径向向外间隔开。 远端通过容纳在远端的孔中的销可分离地附接到外护套,以及可操作地接合到销并连接到外护套的保险丝。

    • A modular lighting fixture may include a housing having opposite ends, an endplate for fastening to one end of the housing, the endplate having a lens receiving face on a first side and an additional-structure-connecting face on a second side. The second side has an outer perimeter portion and a first peripheral surface, the first peripheral surface being inward of the outer perimeter portion. An additional structure is provided having a second peripheral surface with substantially similar contour as the first peripheral surface on the second side of the endplate. The additional structure is connected to the endplate with the second peripheral surface being proximate to the first peripheral surface of the second side of the endplate. A modular lighting fixture may include first and second elongate housings each having ends, pairs of endplates for being respectively mated with the first and second ends of the first and second elongate housings, the endplates each having a rim, and a bridge adapted for joining one of the endplates of the first elongate housing with one of the endplates of the second elongate housing by sealing cooperation with the respective rims thereof. A lighting fixture may have one or more isolated raceways therein.
    • 模块化照明器具可以包括具有相对端的壳体,用于紧固到壳体的一端的端板,端板在第一侧上具有透镜接收面,在第二侧具有附加结构连接面。 第二侧面具有外周部分和第一周边表面,第一周边表面是外周部分的内侧。 提供了另外的结构,其具有与终板的第二侧上的第一周边表面基本相似的轮廓的第二周边表面。 附加结构连接到端板,其中第二周边表面靠近端板第二侧的第一周边表面。 模块化照明器具可以包括每个具有端部的第一和第二细长壳体,成对的端板用于分别与第一和第二细长壳体的第一端和第二端配合,每个端盖具有边缘,以及适于连接一个 通过与其相应的边缘的密封配合,第一细长壳体的端板与第二细长壳体的端板中的一个接合。 照明器具可以在其中具有一个或多个隔离的滚道。

    • A luminaire includes a housing defining a cavity with an open end. A double acting reflector system is mounted in the cavity that includes a first reflector of a generally concave configuration. A light source is positioned in the upper portion of the cavity. The first reflector is configured to capture a substantial portion of the light emanating from the light source and reflect it downward. The reflector system also includes a second reflector extending down from a lower rear edge of the first reflector. The second reflector is configured to capture a portion of the light projected from the first reflector and reflect it outwardly and downwardly to help form a rectangular lighting pattern on a planar surface. A transparent, nonprismatic lens is included which is secured to the housing to cover the open end. The housing may include an aperture with a removable plug to provide access to the light source for connection of wires and the like.
    • 灯具包括限定具有开口端的空腔的壳体。 双作用反射器系统安装在空腔中,其包括大致凹形构造的第一反射器。 光源位于空腔的上部。 第一反射器配置成捕获从光源发出的光的大部分并将其向下反射。 反射器系统还包括从第一反射器的下后边缘向下延伸的第二反射器。 第二反射器被配置为捕获从第一反射器投射的光的一部分并将其向外和向下反射,以帮助在平坦表面上形成矩形照明图案。 包括透明的非乳化透镜,其被固定到壳体以覆盖开口端。 壳体可以包括具有可移除插头的孔,以提供对光源的接近以连接电线等。
