Abstract

The present invention includes a modular component skate wheel particularly usable in connection with preferably an in-line skate boot. All of the components are interchangeable and the components in preferred embodiments include snap fit surfaces. Preferably, a three piece wheel with interchangeable tire, hub and stationary drum is included to allow the user to adapt the modular skate wheels to the intended purpose. The tires may contain at least one light source for purposes of illuminating the preferably clear, transparent (or translucent) tires. The removable inner hub may be adaptable to contain a two-bearing configuration similar to existing skate wheels for the lightweight skating and maneuverability, such as required for roller hockey or speed skating. A generator may be snapped into the inner hub and used as a means of power to illuminate a light source contained within the tire or located on the boot if a flashy appearance is desired. This arrangement permits the user to mix and match components, so as to customize the modular skate wheel.

Claims

1. A modular skate wheel having interchangeable components and comprising:

a removable modular stationary drum including mounting means thereon for a ring magnet;

at least one ring magnet having a plurality of poles mounted upon said stationary drum;

a removable modular hub rotationally mounted upon said stationary drum for containing said ring magnet and power generating means therewithin and having an exterior radial surface thereof;

ring bearing means mounted between said removable hub and said stationary drum for rotational movement of said removable hub;

a modular tire assembly including a tire rim, a light source which is electrically connected to said power generating means, and a light transmitting tire mounted upon said tire rim radially of said light source, said tire rim having an outer radial surface with a recess formed therein which cooperates with a recess formed in an inner radial surface of the light transmitting tire to form a chamber for receiving said light source, said modular tire assembly together with said included light source removably carried by said removable modular hub adjacent said exterior radial surface thereof; and

said light source transmitting light in substantial amounts both radially and axially through said light transmitting tire.

2. The modular skate wheel of claim 1 wherein said modular tire assembly comprises a tire rim for removable mounting upon the exterior radial surface of said modular hub and a tire mounted on said tire rim.

3. The modular skate wheel of claim 1 wherein said removable hub has a removable face.

4. A. The modular skate wheel of claim 1 wherein said removable hub contains direct current power generating means therewithin.

5. The modular skate wheel of claim 1 wherein said tire is attached to said removable modular hub by snap fit attachment means.

6. The modular skate wheel of claim 1 wherein said light transmitting tire further contains a reflective strip.

7. The modular skate wheel of claim 1 wherein said light source generates light proportional to the number of poles of said ring magnet.

8. The modular skate wheel of claim 1 wherein said light source comprises an electrical coil which is disposed radially adjacent said ring magnet for compactness of design.

9. The modular skate wheel of claim 1 wherein said removable modular hub includes at least two electrical conducting terminals.

10. The modular skate wheel of claim 2 wherein said tire rim comprises electrically conductive material and said removable modular stationary drum comprises electrically conductive material and wherein said tire rim is mounted upon said removable drum for electrical contact therebetween.

11. The modular skate wheel of claim 1 wherein said removable modular stationary drum includes slip fit means for mounting upon a skate axle carried by said skate.

12. The modular skate wheel of claim 1 wherein said at least one ring magnet comprises removable modular stationary drum includes at least two commutators.

13. The modular skate wheel of claim 1 wherein said at least one ring magnet is secured to a stationary drum.

14. The modular skate wheel of claim 1 wherein said ring magnet comprises a rare earth, aluminum, neodymium, nickel, cobalt, alnico or flexible magnet.

15. The modular skate wheel of claim 1 wherein said two or more ring magnets, stacked and secured to the stationary drum.

16. The modular skate wheel of claim 1 wherein said light source comprises electrically conducting coil mounted windings wound between inner and outer armature assemblies, with each coil wire end connected to conducting terminals.

17. The modular skate wheel of claim 1 wherein said light generating and emitting means comprises a current generator which includes armature arms protruding laterally from the coil and radially overspreading said ring magnet.

18. The modular skate wheel of claim 1 further comprising a power transfer coupler with at least two electrical terminals, said power transfer coupler being electrically connected to said stationary drum for transferring power from the wheel to a skate boot.

19. The modular skate wheel of claim 18 wherein said electrical connection is by slip fit means.

20. The modular skate wheel of claim 18 wherein said power transfer coupler is carried by a skate boot.

21. The modular skate wheel of claim 1 wherein said light source includes a compact generator with an in-line diode contained within the removable modular hub to produce an intermittent direct electric current.

22. The modular skate wheel of claim 1 wherein said light source includes a compact generator with a bridge rectifier contained within the two-piece hub to produce continuous direct electric current.

23. The modular skate wheel of claim 1 wherein said light source includes a compact generator with a capacitor contained within the modular hub to produce intermittent bursts of direct electrical current.

24. The modular skate wheel of claim 1 wherein said light source includes a direct current generator contained within said modular skate wheel to produce power whether the wheel is rotated forward or backward.

25. The modular skate wheel of claim 1 wherein said light source includes a compact generator with a two-part armature design containing a spindle and containing arms extending laterally from an induction coil and radially over the ring magnet.

26. The modular skate wheel of claim 1 wherein said light source includes a compact generator and an armature arrangement having a plurality of armature arm in which the number of armature arms may be varied to produce unique and distinct electrical output patterns from the generator.
