Definitions

  • This invention relates generally to a lighting fixture having a tiltable and rotatable light bulb socket assembly on an extension arm.
  • a tilt-turn joint is situated at the end of an extension arm and consists of a rotatable collar which carries a second arm arranged in bearings for tilting movement.
  • the second arm carries at its outer end a standard light socket fitting.
  • the socket and tilt-turn joint are enclosed within a cylinder, because the bare socketand screw-on joint arrangement is not attractive.
  • the purpose of this invention is to provide a lighting fixture of the described type which avoids the disadvantages of the known arrangement and on which parts need not be hidden for attractiveness. It is also a purpose of the invention to provide a lamp of simple construction using a minimum of parts while permitting a tilt-turn arrangement.
  • the lamp socket extension has a slot in which a collar is located for tilting movement, the collar being rotatably positioned on an extension arm.
  • the collar can be formed with a cylindrical part having parallel end faces, which is fitted in the slot for swing or tilt movement.
  • the socket itself performs the functions which previously required a separate joint assembly. Due to the invention, a construction is possible which is not only simple, but also pleasantly aesthetic. The collar moves within the slot and is out of sight in most positions of the socket. The normal smooth cylindrical construction of the lamp socket and extended part give the lamp a pleasing appearance even without a decorative covering tube. Due to the fact that the extended socket body forms part of the joint, the whole construction is simplified and the new type lamp can be produced at lower cost despite its other advantages.
  • a further suggestion of the invention is that the width of the slot corresponds to the diameter of at least part of the collar, or to the parallel end faces of the cylinder part.
  • Another suggestion is that the electric wiring for the lamp socket is conducted through the extension arm tube and through the turn-tilt joint into the extended lamp socket without any open zones or areas. The advantage of such construction is that all wiring can be enclosed for both safety and aesthetic reasons.
  • the extended part of the socket with two coaxial bores, one on each side of the slot, each bore having a larger externaldiameter, so that a shoulder is formed for supporting a securing means which is connected to the collar or the cylinder.
  • the securing means consists of screws which are screwed into the collar or cylinder part.
  • spring washers may be provided between the screw heads and the bore shoulders.
  • securing means are locked relative to the collar, such as by using a suitable adhesive.
  • a ring having axially extending spring arms is fitted between the socket and the extended part.
  • a decorative tube such as a chromeplated tube, can be pushed over the spring-loaded arms to exert a friction-grip pressure on the inside surface of the tube to thereby hold it in a preselected position.
  • FIG. 3 is a perspective view of spring means for bold ing a cover tube
  • FIG. 4 is a front elevational view of a cylinder with a rotatable joint and extension arm; and FIG. 5 is a side elevational view of the elements of FIG. 4.
  • the lighting fixture has a light bulb socket I to which is secured in axial alignment an extended part 2.
  • the light bulb socket and extended part may be screwed together or joined by any other suitable means (not shown).
  • Disposed between socket 1 and extended part 2 is a ring 3, best seen in FIG. 3, which carries oppositely and axially directed spring arms 4.
  • Spring arms 4 exert a spring pressure on the inside of a tube 5 which is assembled over the socket and extended-part assembly. The spring arms grip the interior surface of tube 5 to thereby hold it in any selected position, with the tube being axially adjustable.
  • Tube 5 is provided with a longitudinal slot 6 through which an arm 7 can pass for allowing relative adjustment of the tube.
  • the opposite end of the tube has removably mounted therein a reflector 8, and an electric light bulb 9 is shown in phantom as being fitted into the socket within the reflector.
  • Socket 1 and extended part 2 may be termed as a lamp socket assembly and are preferably of equal diamcollar 14 to thereby limit the rotation of collar 14 to slightly less than 360.
  • Collar 14 is formed as part of a cylindrical body 22.
  • Extended part 2 is provided with a slot 15 which receives cylindrical body 22, with the side walls 23 and 24 of the cylindrical body being dimensioned so as to be received in slot 15.
  • a recess 25 in the form of a 90 sector is formed in cylindrical body 22, providing space for electrical cable 11 when the lamp is tilted. Approximately 90 of tilt is provided for.
  • the extreme relative positions of extension arm 7 are shown in solid and phantom lines in FIG. 1.
  • side walls 23 and 24 of cylinder 22 have threaded bores 16 for receiving screws 17.
  • Spring washers 19 seat on the shoulders 20 of bores 21 formed in extended part 2 in order that the screw heads 18 provide a frictional drag force between cylindrical body 22 and extended part 2. If desired, once the friction has been adjusted, an adhesive can be applied to the screw threads.
  • socket 1 and extended part 2 forming the socket assembly are formed of plastic material.
  • a lighting fixture having a light bulb socket assembly including a slot and means defining a rotatable, tiltable joint, said means constituting part of said assembly and including a rotatable collar having parallel side walls, the spacing between said side walls being substantially that of the width of said slot, said collar being rotatably mounted on an extension arm, said socket assembly slot permitting tilt action of said collar with'respect to said socket assembly, said rotatable and tiltable means further including coaxial bores in said socket assembly having shouldered recesses, threaded aligned bores in said collar and screws acting between said coaxial bores and said threaded bores, said recesses in said coaxial bores receiving the heads of said screws and further including washers surrounding said screws beneath the heads thereof and acting against said shouldered recesses, said screws and washers acting between said coaxial bores and said threaded bores for pivoting said collar with said collar assembly.
  • said light bulb socket assembly includes a cylindrical socket portion and a cylindrical extended portion connected to said socket portion in axial alignment, said cylindrical socket and said extended portion being of substantially equal outside diameter.
  • said spring means includes a ring and a plurality of spring arms extending generally perpendicularly from the plane of said ring, some of said spring arms extending in one direction and the other of said spring arms extending in an opposite direction.
