Multiple position lamp

Claim 1

A multiple position lamp comprising; a base; a telescopic body mounted to said base, said body including first and second tubular members, said first member being fixed to said base and being formed with a longitudinal rib on an interior surface thereof, said second tubular member being telescopically received within said first tubular member and being rotatably movable to said first tubular member, a ring being disposed within said first tubular member and being formed of a groove for slidably receiving said rib for vertical movement; and a block member, and means to connect said block member to said second tubular member and means to connect said block member to said ring, said block member being formed with a radial flange for abutting said rib in rotation of said second tubular member in said first tubular member so as to limit rotational movement of said second tubular member relative to said first tubular member to less than 360°; said ring being of annular configuration and having an outer circumference slidably disposed with said first tubular member and an inner circumference slidably disposed with said block member; a receptacle adapted to receive a lamp; and means for mounting said receptacle to said second tubular member for movement therewith; further comprising a collar, said collar being disposed around said tubular members and being formed with means to releasably interconnect said tubular members; whereby on releasing said tubular members said second member vertically slides with said block member on the rib of said first member and rotates within the block member until said flange abuts said rib; said rib having parallel sides, and said flange being formed with a circumferential outer surface for slidably engaging the inside of said first member and parallel side surfaces for abutting said rib.
