Abstract

A method and apparatus for providing a pace setting light for joggers, with the method comprising projecting a beam of light directly onto a jogging track to provide a spot of light on the track, and thereafter uniformly moving the projected spot of light around the track on the jogging surface of the track to provide a moving and pace setting spot of light. The apparatus comprises a frame having a path in the shape of the jogging track, a light beam source movably mounted on the path of said frame, power means on the frame to move the light beam source along the path, with the light beam source being electrically connected via slip rings to a source of electrical energy.

Claims

1. A device for projecting a moving spot of light onto a jogging track comprising,

a frame corresponding to the shape of said jogging track,

power means mounted to said frame, said power means having a power take-off shaft,

a power gear mounted on said power take-off shaft of said power means,

a first continuous flexible toothed belt meshed with said power gear for constant velocity driven movement thereby,

a driving gear meshed with said power gear,

a second continuous flexible tooth belt meshed with said driven gear for constant velocity movement therewith,

said first and second flexible toothed belts being in parallel spaced apart relationship above said frame, and corresponding to the shape of said frame,

means extending upwardly from said frame to support said first and second flexible toothed belts in said parallel spaced apart relationship,

a light beam source in secured relationship to said first and second toothed belts for constant velocity movement with said belts when said belts are driven, said light beam source being electrically connected to a source of electrical energy.

2. The device of claim 1 wherein the electrical connection of said light beam source to a source of electrically energy is by an electrically conductive slip ring.

3. The device of claim 1 wherein said light source has means to vary the shape of said spot of light projected on said track.
