摘要： In a floor lamp having, as a stand, upper and lower telescoping rigid tubes extending between a supporting base and a supported lamp socket, an electrical cord extends from the base to the socket through a spring-like plastic sleeve, which has an upper portion that is fixed to the upper tube, a medial portion that is extended linearly through the lower sleeve and a lower portion that is coiled compactly in the base. Reciprocation of the upper tube in the lower tube in order to adjust the height of the socket causes more or less of the plastic sleeve to be stored in its lower coiled portion while preventing fouling of the electrical cord as a result of frequent raising and lowering of the stand.

摘要： A floor lamp with a pair of rotatable tubular members defining a vertically extendable telescopic body. The larger tubular member is provided with an internal longitudinal rib. A pair of pins project from an exterior surface of the smaller tubular member at one side thereof, the ends of the pins out of contact with the interior surface of the larger tubular member. A cylindrical guide formed with a longitudinal slot is captively held between the projecting pins, the rib received within the slot. As the smaller tubular member is rotated relative to the larger tubular member, the pins engage the rib and limit rotational movement to less than one complete revolution.

摘要： An improved swivel fitting for interconnecting two tubular members which permits a range of relative swinging movement of the conduits relative to another, and wherein a cord or fiber optic length is adapted to be passed. It includes a housing composed of mating members, one of which is on the end of each conduit. In mated relation, a joint is defined between the conduit ends in which there is an internal annular path for the cord. The open ends of the conduits communicate with the path in the housing. The assembly is held in mated relation by a headed screw passed through a central, lateral, through hole in the housing members, and an ut is provided for threaded adjustment on the end of the headed screw. The central lateral through hole is sized to receive a hub structured with oppositely extending frustoconical portions and the hub has a through bore to receive the screw. The headed screw and nut are sized to apply a degree of force to compression washers which bear against the hub to selectively increase or decrease the friction between the housing members to select the degree of torque needed to swing the conduits relative to one another to permit or restrain swinging movement of angular adjustment of the conduits relative to one another while the cord is captivated within the internal path of the housing.
摘要翻译： 一种用于互连两个管状构件的改进的旋转接头，其允许导管相对于另一个的一定范围的相对摆动运动，并且其中绳索或光纤长度适于通过。 它包括由配合构件组成的壳体，其中一个位于每个管道的末端。 在配合关系中，在导线端部之间限定了一个接头，在该端部中有一个用于电线的内部环形路径。 导管的开放端与壳体中的路径连通。 组件通过穿过壳体构件中的中心的侧向通孔的头螺钉保持配合关系，并且在头螺钉的端部上设置用于螺纹调节的装置。 中心横向通孔的尺寸被设计成接收由相对延伸的截头圆锥形部分构成的毂，并且毂具有用于容纳螺钉的通孔。 头部螺钉和螺母的尺寸被设计成对压紧垫圈施加一定程度的力，所述压力垫圈承受轮毂，以选择性地增加或减小壳体构件之间的摩擦力，以选择相对于彼此摆动管道所需的扭矩程度， 当绳索被吸收在壳体的内部路径内时，限制导管相对于彼此的角度调节的摆动运动。

摘要： A wall mountable light fixture with a dimmer for controlling luminescence and having a plurality of articulated arms that are movable between a retracted position adjacent the wall and an extended position outwardly of the wall. The arms are interconnected by swivel joints, each of which includes a pair of rotatable cooperating members that are juxtaposed in mating relationship. The mating face of each rotatable member is formed with an arcuately disposed race of predetermined length. A ball received within a channel formed by the races of juxtaposed rotatable members constrains the swivel joint to a maximum rotation of one revolution.
