Description:
FIELD OF THE INVENTION 
     The present invention relates generally to the field of illuminated ornaments, and more specifically to illuminated Christmas ornaments which contain a music-producing mechanism and are decorated with acetate shrink wrap. 
     BACKGROUND OF THE INVENTION 
     There are many types of illuminated ornamental devices presently available to the public. Often, such devices operate using conventional household alternating current, thereby requiring unsightly wires and consuming large quantities of energy. Music boxes are also many and varied in the prior art. However, no prior art ornaments have combined music with self-powered illumination in such a manner that the entire decorated surface can be brightly illuminated. 
     One example of prior art ornaments is U.S. Pat. No. 2,726,320, which discloses an ornament containing an electric light bulb connected to an electric cord and powered by household alternating current. 
     Another example, U.S. Pat. No. 3,303,734, discloses a Christmas ornament with a music box inside, but without a light. 
     The ornament shown in U.S. Pat. No. 3,873,880 is self-powered, but the arrangement of the battery pack and neon lamps permits only partial illumination of the ornament when lit. Moreover, it would be impossible to decorate this ornament with acetate shrink wrap and still have access to the mechanism of the ornament to change the battery or the light bulbs. 
     In the well-know method of decorating objects with acetate shrink wrap, the desired design is printed directly on a flat, rectangular sheet of acetate shrink wrap (commonly made from extruded polyvinylchloride film), then the rectangular sheet of acetate is formed into a cylinder. Next, the cylinder is slipped over and positioned on the object to be decorated. Finally, heat is applied, &#34;shrinking&#34; the sheet so it forms a tight skin around the object. Due to the strength of the wrap, the ornament cannot be separated along any seam covered by the decorative acetate sheet. 
     SUMMARY OF THE INVENTION 
     The present invention describes a self-powered, illuminated ornament decorated with acetate shrink wrap over a substantial portion of its surface in which the light source is placed within a hollow, ornamented container in such a manner that when the light is lit, the entire decorated surface is illuminated. In a preferred embodiment of this invention, a means to produce music is also contained within the ornament. 
     The light source, the power source, the music-producing mechanism, and the circuitry connecting all of these elements are so arranged that all of the opaque components are clustered towards one end of the hollow ornament and stacked into a modified pyramid. This arrangement creates sufficient space around the opaque components that the light from the light source illuminates the entire decorated surface. 
     The hollow housing of the ornament is so constructed that it is separable into at least two parts. One part can be removed, allowing access to the power source, commonly a 9-volt battery. A particular feature of the preferred embodiments is the particular arrangement of the battery holder in a chordal section of the spherical ornament. The cover to the battery section slides off revealing only the battery holder, thus permitting the battery to be exchanged without exposing the delicate interior light and music components to damage. Unlike a hinged door arrangement, the sliding door arrangement has the additional advantage in that it can be molded in one piece, making this particular arrangement easier and more economical to manufacture. When necessary, the components forming the illuminating and musical portions of this ornament can be disassembled for repairs and changing the light source, commonly a light bulb. 
     The switch for regulating the light and musical elements of this ornament extends from the exterior of the ornament. The switch connects the electric circuitry and power source without any complete electrical conductors between the power source and the operator, thus the sliding door can be completely separated from the rest of the ornament. 
     The accompanying drawings show, by way of example, embodiments of the self-powered illuminated ornament forming the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     In the embodiment of the present invention as described in FIG. 1, the source of illumination, light bulb 14, is screwed into light bulb holder 16. Light bulb holder 16 is inserted into circuit board 20. Integrated circuit 18 is programmed to play any desired musical selection and is also inserted into circuit board 20. A suitable circuit for this purpose is described in detail in U.S. Pat. No. 4,250,787. 
     Circuit board 20 is attached by screws or other means to battery bracket 22. A space is maintained between circuit board 20 and battery bracket 22 by means of columns 21 and pins 19. Any number of columns or pins are suitable as long as they are sufficient to maintain the desired space between circuit board 20 and battery bracket 22. Speaker 58 is located in a recess at the top of battery bracket 22. Positive battery contact 26a and negative battery contact 26b are attached to circuit board 20 by conventional means. Positive battery bracket 26a and negative battery bracket 26b are bent in a manner to fit into the spaces provided within battery bracket 22. Battery bracket 22 is shaped so that a conventional 9-volt battery will fit into battery bracket 22 and make contact with negative and positive battery contacts, respectively 26a and 26b. 
     Stud guide 56 is attached to battery bracket 22. Stud 54 is threaded through stud guide 56. One end of stud 54 terminates in button switch 28. The other end of stud 54 is so constructed that it will contact and compress key disc 52 when button switch 28 is depressed. The compression of key disc 52 will complete the electrical circuit on the the circuit board permitting the operation and control of the musical and illuminating elements of this particular embodiment of the present invention. 
     When ornament 8 is completely assembled, the light emitted and the music played within ornament 8 can be regulated by sufficient pressure applied to spring lock switch 40, thereby depressing button switch 28. Spring lock switch 40 is inserted through battery door 42. 
     Musical and lighting apparatus 15, when completely assembled, can be placed entirely within cover 6 of ornament 8, illustratively a 31/4 inch spherical Christmas ball. Decorative acetate shrink wrap 7, which covers a substantial portion of cover 6, is not broken or disturbed by assembly and disassembly of musical and lighting apparatus 15. 
     Musical and lighting apparatus 15 is secured within cover 6 by fixing screws 32a and 32b or other conventional means. In this particular embodiment, fixing screws 32a and 32b are inserted through battery bracket screw appertures 24a and 24b and threaded into fixing screw holders 12a and 12b. Fixing screw holders 12a and 12b are part of cover 6 in this embodiment. 
     Battery door 42 is so constructed as to include locking legs 34a-d. Locking legs 34a-d wedge into locking shelves 10a-d, formed as part of cover 6. To assemble, battery door 42 is slid over cover 6, and locking legs 34a-d will then engage together with locking shelves 10a-d. 
     In the particular embodiment described in FIG. 1, battery door 42 also has standing legs 38a-c permitting ornament 8 to stand on a surface, when it is not hung on a Christmas tree or string by hook 2. Battery door 42 also has finger grips 36a and 36b providing for easy opening and closing of battery door 42. 
     FIG. 2 is an exploded, diametric section of cover 6, and illustrates the details of battery bracket 22. In particular, FIG. 2 discloses the placement of speaker 58 within a recess in battery bracket 22, as well as the location of stud 54 within stud guide 56. Fixing screw holders 12a and 12b are also visible in this section. Cap 4, which was hidden from view in FIG. 1, is discernable in FIG. 2. 
     FIG. 2 also illustrates how decorative acetate shrink wrap 7 extends along the surface of cover 6. 
     FIG. 3 shows how battery door 42 can be slid off cover 6 in order to open ornament 8. 
     FIG. 4 shows ornament 8 once battery door 42 is lifted. Furthermore, FIG. 4 illustrates the positions of locking legs 34a-d and locking shelves 10a-d. It also demonstrates the ease with which battery 30 can be replaced when necessary. 
     The details of the interior of battery lid 42 are described in FIG. 5. Channels 50a and 50b fit together with channel guides 48a and 48b (illustrated in FIG. 4), when cover 6 and battery lid 42 are slid together in the completely assembled ornament 8. 
     Battery lid 42 is shown from the side in FIG. 6, demonstrating the configuration of locking leg 34a. FIG. 3 also shows finger grips 36a and 36b in opposition to each other and the full complement of standing legs 38a-c. 
     The greatly enlarged cross-section of spring lock switch 40, in FIG. 8, shows the placement of spring 44 in relation to spring lock switch 40. 
     FIG. 7 is an embodiment of the present invention where cover 60 is attached to battery lid 62 by turning screw threads 64 into receiving threads 66. 
     It is expected that many variations can be made in the method of assembling the cover and the battery door of the ornament, the types of lights used, and so forth. In addition, the cover may be formed from a number of molded pieces, which are then assembled into one unit and covered with the decorative acetate shrink wrap. These and other variations can be made in the detailed construction, but it shall be understood that such changes are within the spirit and scope of the present invention as defined by the following claims.
