(Cl. 240-) The present invention is directed to the provision of decorative displays, more particularly to illuminated displays with changing color or light patterns serving .to attract attention of the viewer.

A variety of situations exist in which it is desirable to provide changing light and color patterns to attract the desired viewers attention. Thus in connection with advertising or the like commercial presentations, it is found that the viewers attentionmay be more readily drawn to the advertising copy or indicia lay-illuminating the advertising material in a decorative and colorful way to set In addition to commercial displays, many other situations exist in which it is desirable-to provide varying light and colorpatterns.

.erata in mind that-the present means, including both method and apparatus, have been evolved, means implementing the provision of :an illuminated decorative display in which the color patterns and lighting may be continuously .changed to provide a dynamicever-varying pattern of changing light thereby increasing the attractiveness or: attention getting quality of the display.

It is accordinglyamong the objects of this invention to provide a decorative display with continuously changing light patterns.

Another object of the'invention isto provide -a display withchanging color patterns.

A.further object of the invention is to provide means for supporting. a plurality of' light bulbs as aunitto implement their use in an illuminated display.

It is also an object to provide an illuminated display unit, adaptedfor use with a variety of like units to obtain a changing. light and color eifect.

A further object is to provide an illuminated-display unit adapted to enhance the attractiveness of a'commercial presentation.

Another object is to provide an illuminated-display 'un'it suitable for use in a decorative arrangement as onChristmas trees or as part of other holiday decorations.

These and other objects of the invention which will become hereafter apparent are achieved by forming a display unit with a base "having recesses therein for the receipt of a plurality of 'lightbulbs. It is preferred that 3,283,136 Patented Nov. 1., 1966.

these light'bulbs beof diflerent colors. A switch preferably ofthe thermal type 'is arranged in a circuit With at least one of the'bulbs, and the switch cyclically activated to make and break the circuit to its associated bulb. The base andthe bulbs mounted thereon are enclosed in a light transmitting housing which may be of any desired shape. Where the display unit isemployed .as a Christmas tree decoration, a snow ball effect may be obtained by forming the housing of white polystyrene of a spherical shape hollowed out to accommodate the bulbs. Where the displayunit is employedin connection with a commercial presentation, various indicia maybe applied to the cover or housing. As a result of the periodic deenergization of one or more .of the .light bulbs on the base, the color and. intensity of the light transmitted by the cover or housing is periodically changed thus providing a dynamic continuously changingdisplay.

The specific details of the invention, and their mode of functioning will be made manifest, and particularly pointed out in clear, concise and exact terms-in conjunction with the accompanying drawings in which:

.FIG. 1 is an exploded perspective view of a display unit formed in accordance ,withthe instant invention and provided with a spherical cover member; and

FIG. 2 is a cross-sectional view through a display unit of the type shown inFIG. 1 with a modified form of cover housing shown partly in perspective; and

FIG. 3 is -a schematic wiring diagram of an electrical circuit showing how the bulbs of a plurality of display units of the type shown in FIGS. 1 and 2 are interconnected; and

FIG. '4 is a cross-sectionalview of another embodiment of the display unit; and

FIG. 5 is a perspective view showing how the display units may be employed in connection with a commercial presentation; and

FIG. 6 is a perspective view showing how the display units maybe employed as a Christmas decoration.

Referring now more particularlytothe drawings,like

numerals in the various figureswill'be emp'loyedto desig- .nate :like parts. ,play unit 10 comprises a base 12 formed of two substantially. symmetrical halves 1=3 'and-14.

As'best seen in FIGS. 1 and 2,the dis- A..channel-shaped passage 15 is formed -to extend through thebase halves 13' and 14 at the lower end thereof as viewed in the drawings. Passage 15'is dimensioned to permit the passage'therethrough of -a multiwire conby a project-ionflfi.

Abu'lb'receiving recess 19jis formed in thebase halves 13 and14, said :recess being dimensioned to receive and retain the base .of the -electricbulbs 'B employed inthe display. In the illustrated embodiment-of theinvent ion three bulbs are employed, and accordingly-three recesses "(labelled 19, 15'" and 19" in FIG. 2) are provided. As

shown it is preferred that the upper wall of the base be stepped between each bulb, thereby implementing the facility with which the bulbs may be manually gripped for insertion and removal from recesses 19.

Extending between a wire of conductor C, which is interrupted by projection 16" beneath the recess 19", is a first base contact strip 22 bent over as viewed in FIGS. 1 and 2 so that the base terminal of the bulb will make contact with this first contact strip 22 when the bulb is inserted in recess 19'". A socket contact strip 23 extends from the wire contacted by the base contact strip 22, up along the side wall of recess 19 in a position to be contacted by the lateral socket terminal of the bulb in recess 19". Contact strip 22 is for-med with projection 24 at the lower end. Projection 24 extends a distance such as to pierce the conventional insulation of conductor C to eflFect an electrical connection with a wire of the conductor C.

A single set of contact strips 22 and 23 has been described; however, it will be understood that a set of like contact strips is provided for each bulb mounted on the base, with the contact Strips extending between one of the wires of conductor C and the terminals of the bulb. Projections 16 which extend into the path of conductor C serve to provide a spacing between the contact strips 22 and 23 and also interrupt the wire with which said contacts are spaced, thereby providing a series electrical connection between the bulbs and the wire to which they are connected in the illustrated embodiment.

It will however be apparent to those skilled in the art that the connectors may be arranged to provide a parallel electrical connection between the bulbs and the conductor wires.

The base halves 13 and 14 are maintained in assembled relationship by means of fastening members 26 illustratively shown as U-shaped spring clips arranged in grooves 27 formed in the outer Wall of the base halves.

The base 12 with its associated bulbs is arranged in a light transmitting cover housing 30 which is preferably formed of a translucent material subject to ready shaping to desired configuration. The housing 30 is formed with an interior recess dimensioned to accommodate the bulbs entirely within the housing, and preferably encompassing the base 12 so as to enclose same.

In FIG. 1 a spherically shaped configuration is provided for housing 30 which is formed of a white styrofoam having a snow ball appearance.

In FIG. 2, the housing is shown as of a rectilinear configuration provided with indicia 35.

Another arrangement embodying the instant inventive concept is shown in FIG. 4 wherein the display device 110 is shown as comprising a base 126 having sockets 127 and 128 to accommodate bulbs above the base, While socket 131- accommodates a bulb beneath the base 126. The housing is formed in two parts with an upper part 133 encompassing the bulbs in sockets 127 and 128, while a lower housing part 134 encompasses the bulb in lower socket 131. Spring clips 135 extend between the housing parts 133 and 134 to maintain them in operative position with respect to the base 126.

As is apparent from FIG. 4, when the housing halves are formed of hollow spheroids of white styroform a snow man shape may be obtained. Depending on the shape employed a variety of other decorative elfects may be produced. The clips 135 when the snow man elfect is desired may be formed of pipe cleaners. The bulb sockets 126,: 128, and 131 maybe electrically coupled either in series or parallel, though as will become hereafter apparent a parallel connection between the bulbs is preferred thereby permitting one of the bulbs on the base to be deenergized without efiecting the other. bulbs to obtain a desired change of color or light.

Where a single display unit 10, or 110 is employed, one or more ofthe bulbs on the base is associated with a switch in its circuit to permit periodic or cyclical de- 4 energization of at least one of the, bulbs to thereby provide for a change in intensity of the light. transmitted through the cover housing. This switching arrangement may be povided in a variety of ways. As shown, it may most readily be obtained by employing a so-called flasher bulb having a thermally responsive element in series with the filament 151, so that as the filament heats up the heat thereof is transferred to element 150 which distorts to break the circuit to the filament.

A plurality of display units 10 or 110 maybe arranged in a circuit as shown in FIG. 3, with one of the bulbs of one base arranged in series with one of the bulbs of another base, and a second of the bulbs of one base in series with a second bulb on another base. It will be understood that a switch is arranged in each of the bulb circuits. This may be accomplished by employing only flasher bulbs, or preferably a single flasher bulb in each circuit.

As shown in the schematic circuit a plug 163 suitable for coupling to a conventional receptacle has one of its leads 165 connected to common connection 168 from which lines 171, 172, and 173 extend in parallel. Each of lines'171, 172, and 173 has series connected bulbs arranged therein. The flasher bulbs are selected to flash at different time intervals so that at least one of the circuits is always energized. They, like the other bulbs, are preferably of difierent colors, the primary colors red, blue and green being preferred.

Operation In use, the display unit 10 may be employed singlyv in which case the bulbs provided are of the flasher type, and if a colored display is desired, the bulbs are ofdifierent colors. After appropriate. electrical connections are made to the display unit one or more of the bulbs will always be illuminated. As any one of the switches or.

has been provided serving to provide a continuously changing light and color pattern which may be incorporated either with commercial presentations or in connection with holiday or the like decorations to increase the attractiveness thereof to the desired viewer.
