Abstract

There is disclosed herein a new form of sign or graphic display which simulates a neon sign. The same comprises a hollow tube or tubes which are formed into desired shapes, such as letters, graphics and the like. These tubes are lit along the side edge by directing illumination to the side thereof, preferably through colored material, paint or dye to provide a colored display. Several arrangements for illuminating the sides of the tubes are disclosed. In the case of flexible vinyl tubing, a method is disclosed for forming the same into the desired shapes by inserting a solid Teflon rod in the tube prior to bending, bending the tube to the desired form, and applying suitable heat in order that the tube will assume the desired shape, then cooling the tubing and removing the solid rod.

Claims

1. A display comprising tubing formed into a desired shape such as a letter, graphics or the like, said tubing comprising hollow tubing substantially in the form of an open 360°

hollow cylinder having ends and an elongated side, and illumination means for lighting the tubing along the side thereof; and

said tubing being adhesively bonded to a panel in the form of a sheet, said panel having a colored area thereon having a configuration co-extensive with the shape of the tubing, said illumination means being disposed on a side of said sheet to supply illumination to and through the colored area to the tubing.

2. A display as in claim 1 wherein a diffuser is disposed between said illumination means and said panel.

3. A display as in claim 2 wherein said illumination means comprises a fluorescent light source.

4. A display comprising tubing formed into a desired shape such as a letter, graphics or the like, said tubing comprising hollow tubing substantially in the form of an open 360°

hollow cylinder having ends and an elongated side, and illumination means for lighting the tubing along the side thereof and said illumination means including a plastic lens configured substantially in the shape of said tubing.

5. A display comprising tubing formed into a desired shape such as a letter, graphics or the like, said tubing comprising hollow tubing substantially in the form of an open 360°

hollow cylinder having ends and an elongated side, and illumination means for lighting the tubing along the side thereof, said tubing being adhesively bonded to a plastic sheet, said plastic sheet being mounted on and spaced from a plastic panel, said plastic panel including lens means formed substantially in the shape of said tubing, and said illumination means being disposed on one side of said lens means and said tubing and sheet being disposed on the other side thereof.

6. A display comprising tubing formed into a desired shape such as a letter, graphics or the like, comprising

tubing substantially in the form of an open hollow cylinder having ends and an elongated side, and said tubing being adhesively bonded to a plastic sheet,

said plastic sheet is mounted on and spaced from a plastic panel, said plastic panel includes lens means formed substantially in the shape of said tubing, and

illumination means for lighting the tubing along the side thereof, said illumination means being disposed on one side of said lens means and said tubing and sheet being disposed on the other side thereof.

7. A display comprising tubing formed into a desired shape such as a letter, graphics or the like, comprising

tubing substantially in the form of an open hollow cylinder having ends and an elongated side and said tubing being adhesively bonded to a panel in the form of a sheet,

said panel having a colored area thereon having a configuration co-extensive with the shape of the tubing, and

illumination means for lighting the tubing along the side thereof, said illumination means being disposed on a side of said sheet to supply illumination to and through the colored area to the tubing.

8. A display as in claim 7 wherein said tubing is hollow vinyl tubing.

9. A display as in claim 7 wherein said tubing is hollow acrylic tubing.
