Apparatus for supporting a lamp on a low-voltage rail
First Claim
1. A lamp removably mounted to a low-voltage rail, said rail consisting of a longitudinally running central track, two side strips running parallel to said track, a transverse support means for supporting said side strips in spaced apart relation to the central track on opposite sides thereof, and a plurality of at least partially free-lying, bare conductor wires running longitudinally between the central track and the side strips, characterized in that:
- said lamp includes a clamping socket removably mounted to the rail, a plug-in socket means for supporting a replaceable incandescent body, an adjustable neck between said clamping socket and said plug-in means, and connecting wires for electrically joining said plug-in socket means and conductor wires, said adjustable neck including a plurality of serially connected joint members, each said joint member having a ball portion and a joint seat portion at its opposite ends, said joint members being serially connected to one another to form said neck, with the ball portion of each joint member being substantially surrounded by the joint seat portion of an associated, next adjacent joint member and held in a frictional engagement that provides a clamping force sufficient to maintain said joint member and said next adjacent joint member in a set position with respect to one another, and means forming borings through said joint members for accommodating said connecting wires.

Abstract
An adjustable neck is provided for adjusting a lamp, in particular a lamp plugged onto a low-voltage rail, in as many alternative directions as possible. The adjustable neck is mounted between a clamping socket of the lamp and the replaceable incandescent body or bulb. The adjustable neck includes several joint members, each consisting of a ball portion that can be plugged into a corresponding joint seat portion of a next adjacent joint member and held there by a friction fit. The incendescent body can be surrounded by a lamp shade provided with ventilating slots. The clamping socket is embodied such that a positive anchoring is achievable even in the case of larger, heavier lamps.
