Abstract

Illuminated footwear having a power source, at least one light source operatively connected to the power source, a switching circuit for selectively illuminating the light source, and a linear side-glow optical conduit positioned exteriorly on the footwear so as to be visible when illuminated, the linear optical conduit having opposed end portions and being capable of emitting light conducted therethrough radially outwardly from its circumferential periphery substantially along its entire length, at least one end portion of the linear optical conduit being positioned and located in close proximity to the light source so as to receive light therefrom when illuminated, the linear optical conduit being illuminated substantially along its entire length when the light source is selectively illuminated. In the preferred embodiment, the linear optical conduit extends substantially around the outer exterior front and side portions of the footwear, although other arrangements are also disclosed herein. An interchangeable filter member may also be positioned between the light source and the one end portion of the linear optical conduit positioned in close proximity thereto, the filter member determining the color of the light directed towards the linear optical conduit end portion. The main features of the present invention are also incorporated into a self-contained portable illumination unit which can be easily attached to and removed from a wide variety of footwear. All embodiments of the present invention are adaptable for use on and with a wide variety of different types and styles of footwear.

Claims

1. Illumination means removably attachable to footwear wherein the footwear includes front, rear and opposed side portions, said illumination means comprising a power source, at least one light source operatively connected to said power source, at least one side-glow fiber optic conduit having opposed end portions, a bracket assembly including means for holding and retaining said power source and said light source, said side-glow fiber optic conduit being capable of emitting light conducted therethrough radially outwardly through its circumferential periphery along substantially its entire length, at least one end portion of said side-glow fiber optic conduit being positioned and located adjacent to said light source, means for holding the one end portion of said side-glow fiber optic conduit adjacent said light source for directing light thereto, said side-glow fiber optic conduit being illuminated substantially along its entire circumferential periphery when said light source is illuminated, and means for removably attaching said bracket assembly to footwear, said side-glow fiber optic conduit extending adjacent to at least a portion of one side portion of the footwear when said bracket assembly is attached thereto.

2. The illumination means defined in claim 1 including means operatively connected to said light source and to said power source for selectively controlling illumination of said light source.

3. The illumination means defined in claim 1 including filter means positioned between said light source and said one end portion of said side-glow fiber optic conduit, said filter means determining the color of light directed towards said conduit end portion.

4. The illumination means defined in claim 1 including means slidably movable along at least a portion of said side-glow fiber optic conduit for attaching said fiber optic conduit to the footwear when said bracket assembly is attached thereto.

5. The illumination means defined in claim 4 wherein said slidably movable attachment means includes at least one hook member positionable to engage the laces associated with particular footwear.

6. The illumination means defined in claim 1 including a second side-glow fiber optic conduit having opposed end portions, at least one end portion of said second side-glow fiber optic conduit being positioned adjacent to said light source, means for holding and retaining the one end portion of said second side-glow fiber optic conduit adjacent said light source, said second side glow fiber optic conduit extending adjacent to at least a portion of the opposed side portion of the footwear when said bracket assembly is attached thereto.

7. The illumination means defined in claim 1 including a reflective cap member engageable with one end portion of said side-glow fiber optic conduit.

8. The illumination means defined in claim 1 wherein said side-glow fiber optic conduit extends substantially around the front portion of the footwear such that the other opposed end portion thereof is positioned adjacent said light source, and means for holding and retaining said other opposed conduit end portion adjacent said light source.

9. The illumination means defined in claim 8 wherein said light source includes at least two light sources, one light source being positioned adjacent one end portion of said side-glow fiber optic conduit and the other light source being positioned adjacent the opposed end portion thereof.

10. The illumination means defined in claim 1 wherein said bracket assembly attachment means is attachable to the rear portion of the footwear.

11. The illumination means defined in claim 1 wherein said side-glow fiber optic conduit includes a light transmitting core surrounded by a tubular cladding made of heat shrinkable material housed within a clear semi-rigid finish jacket.

12. The illumination means defined in claim 11 wherein said tubular cladding is uniformly spaced from said light transmitting core.

13. The illumination means defined in claim 11 wherein the refractive index of said tubular cladding is relatively low compared to the refractive index of said light transmitting core.

14. Illumination means removably attachable to footwear wherein the footwear includes front, rear and opposed side portions, said illumination means comprising a power source, at least one light source operatively connected to said power source, at least one fiber optic conduit having opposed end portions, a bracket assembly including means for holding and retaining said power source and said light source, said fiber optic conduit having a light transmitting core surrounded by a cladding made of a heat shrinkable material, said light transmitting core and said cladding being housed within a substantially clear, semi-rigid finish jacket, a uniform space existing between the inner periphery of said cladding and the outer periphery of said light transmitting core, said fiber optic conduit being capable of emitting light through its circumferential periphery along the length thereof, at least one end portion of said fiber optic conduit being positioned and located adjacent to said light source, means for holding the one end portion of said fiber optic conduit adjacent said light source for directing light thereto, said fiber optic conduit being illuminated along its entire length when said light source is illuminated, and means for removably attaching said bracket assembly to footwear, said fiber optic conduit extending adjacent to at least a portion of one side portion of the footwear when said bracket assembly is attached thereto.
