Abstract
A multimovable plastic lamp fixture. In the preferred embodiment, the lamp fixture includes a pair of lampholders for supporting a pair of floodlights or the like. Each of the lampholders are attached to a base by means of a ball and socket-type joint. The ball joint is located off-center and provides spherical positioning of the lights. A gasket located in the interior of each socket prevents moisture from entering the base and, in addition, maintains each lampholder in position due to friction. The ball and socket joint includes a knee ball cover having a semi-spherical surface for engaging the ball joint. Tabs located on the outer surface of the knee ball cover limit the rotational movement of each lampholder with respect to the base.
Claims34
A lighting fixture, said fixture comprising:
- (a) a lampholder for receiving a floodlight or the like;
- (b) a base for establishing electrical and mechanical connections with a source of electrical power, said base having a circular aperture for receiving one end of said lampholder;
- and
- (c) a ball and socket assembly connected between said base and the end of said lampholder for supporting said lampholder and permitting said lampholder to be manually positioned with respect to said base;
- said assembly including:
- (i) a semi-spherically shaped portion attached to said one end of said lampholder and having a diameter larger than the diameter of said circular aperture in said base thereby preventing its passage through said circular aperture;
- (ii) a stem portion attached to said semi-spherically shaped portion and aligned perpendicularly to the surface of said semi-spherically shaped portion and extending through said circular aperture;
- (iii) a hemispherical shaped portion adapted to mate with said semi-spherically shaped portion and having an elongated slotted aperture for receiving said stem;
- and (iv) retaining means attached to said stem for applying a predetermined force on said hemispherical shaped portion.
A ball and socket assembly connected between a base and an end of a lampholder for supporting said lampholder and permitting said lampholder to be manually positioned with respect to said base said base including a circular aperature therein, said assembly comprising:
- (a) a semi-spherically shaped portion attached to said one end of said lampholder and having a diameter larger than the diameter of said circular aperture in said base thereby preventing its passage through said circular aperture;
- (b) a stem portion attached to said semi-spherically shaped portion and aligned perpendicularly to the surface of said semi-spherically shaped portion and extending through said circular aperture;
- (c) a hemispherical shaped portion adapted to mate with said semi-spherically shaped portion and having an elongated slotted aperture for receiving said stem;
- and
- (d) retaining means attached to said stem for applying a predetermined force on said hemispherical shaped portion.
