Abstract
Abstract A skate has a wheel rotatably mounted on an axle with a light emitting element mounted on the wheel for making the wheel illuminative when an electrical potential is applied to the light emitting element. The electrical potential can be supplied by a battery installed within the wheel through a switch which can be actuated by rotating a cap movably mounted on the hub of the wheel or contacts actuated by centrifugal force upon rotation of the wheel. The rotor and stator of an electrical generator can be mounted on the axle and wheel to generate the electrical potential in an embodiment which does not require a battery.

Total Claims: 4
Claim 1
Independent Claim
217 words
In a skate having an axle, and a wheel rotatably mounted on said axle, the improvement which comprises a pair of terminals mounted within said wheel and adapted to have an electrical potential applied thereacross, and light emitting means operatively connectable to said terminals, mounted on said wheel and responsive to application of said electrical potential thereto for emitting light, a source of electrical potential removably mounted within said wheel, contact means connected between said source of potential and at least one of said terminals, said contact means being operative between an open state in which application of said electrical potential to said one of said terminals is interrupted for extinguishing said light emitting means and a closed state in which said potential is applied to said one of said terminals or illuminating said light emitting means, and a translucent cap member mounted over the hub of said wheel and being illuminated by said light emitting means when said potential is applied to said terminal, said cap member being selectively engageable with said contact means and movably mounted on said wheel for movement between a first position in which said contact means is caused to be in said open state and a second position in which said contact means is caused to be in said closed state.

In a skate having an axle, and a wheel rotatably mounted on said axle, the improvement which comprises a pair of terminals mounted within said wheel and adapted to have an electrical potential applied thereacross, and light emitting means operatively connectable to said terminals, mounted on said wheel and responsive to application of said electrical potential thereto for emitting light, a source of electrical potential removably mounted within said wheel, contact means connected between said source of potential and at least one of said terminals, said contact means being operative between an open state in which application of said electrical potential to said one of said terminals is interrupted for extinguishing said light emitting means and a closed state in which said potential is applied to said one of said terminals or illuminating said light emitting means, and a translucent cap member mounted over the hub of said wheel and being illuminated by said light emitting means when said potential is applied to said terminal, said cap member being selectively engageable with said contact means and movably mounted on said wheel for movement between a first position in which said contact means is caused to be in said open state and a second position in which said contact means is caused to be in said closed state.
Claim 3
Dependent Claim
19 words
Apparatus according to claim 1 wherein at least part of said contact means is mounted on said cap member.
Claim 4
Dependent Claim
33 words
Apparatus according to claim 2 wherein said cap member is removably mounted on said wheel for providing access to at least one of said light emitting means and said source of electrical potential.
