Multiple position lamp

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.
