Description:
FIELD OF THE INVENTION 
     This invention relates to an adjustable light display assembly of the track light variety which can assume various configurations including wall and ceiling panels, support stands, including racks and advertising and display devices and the like. 
     BACKGROUND OF THE INVENTION 
     Article display units are known in which interlocking elongated members are assembled to form slotted panels, the slots of which receive mounting devices such as clips or hooks for directly or indirectly supporting articles. These display units may be wall mounted or free standing. Such display units are the subject of my previous U.S. Pat. Nos. 4,323,163 and 4,420,087. FIG. 24 of the &#39;087 patent discloses a light tube located inside the display unit to provide a “dramatic effect”. 
     Track-lighting systems for general purpose illumination have been known for sometime. They are used in homes, factories, art galleries and industrial areas generally. 
     Electrical outlet devices are well known such as Glen, U.S. Pat. No. 5,052,937, Thurlow, U.S. Pat. No. 4,967,327, Smart, U.S. Pat. No. 4,690,474, Pantin, U.S. Pat. No. 3,012,217, Boyd, U.S. Pat. No. 3,308,416 and Grau, U.S. Pat. No. 5,517,391. 
     OBJECTS AND SUMMARY OF THE INVENTION 
     It is an object of this invention to provide an adjustable light display assembly of a track light type adaptable to various structures such as walls and ceiling panels, racks, poles or standards and advertising structures and the like. 
     Another object of this invention is to provide an adjustable light display assembly which is adaptable to standard manufacturing equipment and readily assembled. 
     A further object of this invention is to provide an adjustable light display assembly which is inexpensive to manufacture. 
     A further object of this invention is to provide an adjustable light display assembly which may be readily moved from one area to another and which is adaptable to both wall panels and free standing stands and racks. 
     Still a further object of this invention is to provide an adjustable light display assembly which can be used in advertising. 
     Yet another object of this invention is to provide an adjustable light display assembly which has the capability of being used at department stores to support articles of clothing and the like. 
     A further object of this invention is to provide an adjustable light display assembly which permits quick adjustments either laterally or vertically of the light mechanism. 
     Another object of this invention is to provide an adjustable light display assembly which has strength to support heavy loads including shelving, garment hangers and the like. 
     In summary, the present invention relates to an adjustable light display assembly capable of being used for multi-purposes in homes, factories and stores and the like which will become apparent from the following detailed description including the following drawings in which;

     DETAILED DESCRIPTION OF THE INVENTION 
     In FIG. 1, the adjustable light display assembly D as shown in the exploded figure, includes a support S which includes interlocking panel members  2  and  4 . The panel members  2  and  4  provide a slot  6  which is generally T-shaped. In the arms of the T-shaped slot  6 , are positioned electrical circuit conducting means  8  and  10 . The electrical circuit conducting means  8  and  10  are generally shown as U-shaped members which run the length of the slot  6 . Instead of the U-shaped members  8  and  10 , electrical tapes can be fixed to the walls of the T-shaped slot  6  as well as other electrical circuit conducting means such as wires or the like. The electrical circuit conducting means  8  and  10  carry a plurality of circuit contacts  12 ,  14 ,  16 ,  18 ,  20  and  22 . 
     As shown in FIGS. 1 and 2, a back-up bar  24  is provided having bracket slots  26 . The back-up bar  24  with the bracket slots  26  positions the bracket  28  by means of lugs  30  and  32 . The lugs  30  and  32  of the bracket  28  lock the adjustable light display unit F in the back-up bar  24 . The bracket slots  26  are sufficiently long to provide clearance for the lugs  30  and  32  to be inserted therein and locked downwardly to prevent accidental removal of the adjustable light display unit F from the back-up bar  24 . It is obvious that other arrangements can be made in the back of the slot  6  to adjustably receive the bracket  28  including extension of the panel members  2  or  4 . 
     Mounted in the slot  6  is a slidable electrical receptacle  34  having contact members  36 ,  38 ,  40 ,  42 ,  44  and  46  engaging the circuit contacts  12 ,  14 ,  16 ,  18 ,  20  and  22 . Although a number of circuit contacts  12 ,  14 ,  16 ,  18 ,  20  and  22  are shown, more or less can be provided as needed depending upon the lighting system. The slideable electrical receptacle  34  may be inserted at the top of the slot  6  (see cap  78 FIG. 8 which is removable). 
     The electrical receptacle  34  is generally T-shaped in configuration and includes plugs insert holes  48 . Above the insert holes  48  is a lever  50  which permits the electrical receptacle  34  to be moved manually up and down in the slot  6 . 
     A plug  52  is provided with prongs  54  which engage the plug insert holes  48 . The number of prongs  54  in the plug  52  will depend upon the number of circuits utilized and carried by the electrical receptacle  34 . At the rear of the plug  52  is an electrical connector  56  carrying a series of contacts  58  as best seen in FIGS. 1A and 1B. The plug  52  at the top thereof includes a dovetail  60 . Wire leads or clips may be used in place of connector  56 . 
     A light receptacle support body  62  includes a slot  64  which receives the arm  66  of the bracket  28 . The dovetail slot  68  receives the dovetail  60  of the plug  52 . 
     The light receptacle support body  62  receives the sleeve portion  70  of the light  72 . The electrical connector  56  on the plug  52  connects with the electrical circuitry(not shown) of the light  72 . 
     FIG. 5 shows a panel P with slots  6  for mounting various adjustable light display units F. It is to be noted that the panel can have straight or curved walls. 
     FIG. 6 shows a free standing display pole X with lights  72  which may carry hangers  74  or a display sign  76 . 
     FIG. 7 shows in general a cross-section of the pole prior to insertion of adjustable light display unit F. 
     FIG. 8 shows a display pole Y which has multiple circuits for supporting hangers  74  or signs  76 . FIG. 9 shows a cross-section of the display pole. 
     An on/off switch  78  can be provided for the adjustable light display assembly D as illustrated in FIG.  1 . Means for supplying electricity to the adjustable light display assemblies D (not shown) would be of standard type and could include a ballast (not shown). 
     While this invention has been described as having preferred design, it is understood that it is capable of further modification, uses and/or adaptations following in general the principle of the invention and including such departures from the present disclosure as come within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features set forth, and fall within the scope of the invention or the limits of the appended claims.
