Display device

Abstract

A portable display device having a base comprising running gear which includes a plurality of wheels and a pulling tongue wherein the wheels may be detachably secured to the base such that the base may be permanently affixed to a given location. A sign is reciprocally mounted on the base by means of a supporting frame such that the sign may be raised or lowered to any desired position through the operation of a lifting mechanism in the form of a power or manually operated winch connected to the sign by a pulley and cable arrangement. Lights may be arranged on both the interior and exterior of the sign and operated by a power supply, in the form of a battery or generator which also may be carried on the base of the sign.

Now that the invention has been described, what is claimed is: .[. 
     
       1.  A display device comprising: a base, a running assembly removably attached to said base, such that said display device may be portable or permanently installed on a predetermined location, a support frame mounted on said base, sign means movably mounted on said frame, positioning means connected to said sign means so as to selectively position it relative to said base, whereby said sign means may be raised or lowered on said frame relative to said base by activation of said positioning means..]. .[.2. A display device as in claim 1 wherein said running assembly further comprises wheel means on which said device is transported, pulling means arranged on said base so as to interconnect said device to a towing vehicle..]. .[.3. A display device as in claim 2 further comprising wheel connecting means including a bar connected to said wheel means and removably connected to said base, bracket means fixedly attached to said base and arranged to attach a portion of each of said bars to said base..]. .[.4. A display device as in claim 3 wherein said bracket is arranged relative to said base such that said bar is positionable in 
     
     
        supported fashion between said bracket and said device..]. .[.5.  A display device as in claim 2 wherein said pulling means comprises a tongue movably mounted on said base such that it may be positioned in either an operative or inoperative position..]. .[.6. A display device as in claim 5 wherein said tongue is telescopically arranged relative to a portion of said base whereby it may be selectively arranged in and out of operative position..]. .[.7. A display device as in claim 5 wherein said tongue is pivotally attached to said base such that it may be pivoted into an extended operative position or non-extended, inoperative position..]. .[.8. A display device as in claim 5 wherein said movably mounted tongue is removably attached to said base whereby said tongue is attached when permanently positioned at a desired location..]. .[.9. A display device as in claim 1 further including base support means movably connected to said base such that said base support means may be moved into and out of operative position, whereby proper orientation of said device is 
     
     
        maintained when arranged in a desired position..]. .[.10.  A display device as in claim 9 wherein said base support means comprises a plurality of outrigger assembly each of which are telescopically and rotationally connected to said base and arranged in spaced relation to one another..]. .[.11. A display device as in claim 10 wherein each of said outrigger assemblies comprise first and second portions movably connected to one another such that said portions can be extended or retracted into and out of operative supporting relation to one another..]. .[.12. A display device as in claim 1 further including guide means arranged relative to said sign means to interconnect said sign means and said frame such that said sign means is guided to move in a reciprocal fashion relative to said frame..]. .[.13. A display device as in claim 12 wherein said guide means comprise at least one collar fixedly attached to each side of said sign means and arranged to movably interconnect said sign means to said frame, such that said sign means is capable of moving in a reciprocal fashion relative to said frame and in a plane substantially common to said 
     
     
        frame..]. .[.14.  A display device as in claim 1 wherein said lift means comprises a winch, a cable means interconnecting said winch and said sign means, at least one pulley means positioned on said device between said winch and said sign means in cooperative working engagement with said cable..]. .[.15. A display device as in claim 14 further comprising power means including an electric motor to operate said winch..]. .[.16. A display device as in claim 14 wherein said cable means and said one pulley is positioned on an interior portion of said frame..]. 17. A display device as in claim 1 further comprising light means mounted on said device so as to illuminate said side means..]. .[.18. A display device as in claim 17 further comprising said light means arranged on said interior of said sign means..]. .Iadd. 19. A display device comprising: a base including an elongated frame assembly disposed in a horizontal plane, a running assembly of approximately complementary size and shape attached to said base, said running assembly including at least two ground-engaging wheels mounted on opposite sides of the running assembly for rotation about a common horizontal axis extending transversely to said running assembly, a support frame configured to define a planar disposition arranged transverse to said common axis and perpendicular to said base said support frame being mounted on said base and extending along substantially the entire length of said base and upwardly therefrom, sign means movably mounted on said support frame, said support frame disposed in at least partially surrounding relation to the outer periphery of said sign means, said sign means movably connected to move vertically in the single plane defined by said support frame along the entire length of travel of said sign means, said sign means including a continuous peripheral portion surrounding an opening, two spaced-apart panels for carrying indicia extending across said opening and supported by said peripheral portion and electric illuminating means disposed between said panels, positioning means connected to said sign means for selectively raising and lowering the latter relative to said support frame and said base, and stabilizing means carried by said base for stabilizing said base, frame and sign against tipping, said stabilizing means including ground-engageable foot members carried by said base and means for adjusting the position of the foot members inwardly and outwardly with respect to the plane of said sign. .Iaddend.
