Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
100 words
An ice hockey puck having a flat cylindrical body of rubber-elastic material in the middle of which a recess is provided for receiving an energizing source which cooperates with at least a light source, the light of which exits at the periphery of said ice hockey puck, said recess also houses said light source and light-guiding channels of highly transparent material are provided between said light source and said periphery of said ice hockey puck, and that the elasticity or hardness of the highly transparent material is substantially similar to the elasticity or hardness of the remainder of said body.
Claim 2
Dependent Claim
100 words
An ice hockey puck having a flat cylindrical body of rubber-elastic material in the middle of which a recess is provided for receiving an energizing source which cooperates with at least a light source, the light of which exits at the periphery of said ice hockey puck, said recess also houses said light source and light-guiding channels of highly transparent material are provided between said light source and said periphery of said ice hockey puck, and that the elasticity or hardness of the highly transparent material is substantially similar to the elasticity or hardness of the remainder of said body.
Claim 3
Dependent Claim
21 words
An ice hockey puck according to claim 1, characterized in that the light source comprises one or more light emitting diodes.
Claim 4
Dependent Claim
18 words
An ice hockey puck according to claim 1, characterized in that the energizing source is a pulsing source.
Claim 5
Dependent Claim
36 words
An ice hockey puck according to claim 1, characterized in that the light source together with an energizing source and electrical or electronic switching or control means are disposed within a transparent housing occupying the recess.
Claim 6
Dependent Claim
29 words
An ice hockey puck according to claim 1, characterized in that the material occupying the light channels provides a transparent body having a cavity for receiving a light source.
Claim 7
Dependent Claim
27 words
An ice hockey puck according to claim 1, characterized in that the light emitting surface of the material in the light channels comprises lens-shaped or pyramid-shaped projections.
Claim 8
Dependent Claim
24 words
An ice hockey puck according to claim 1, characterized in that a magnetically operated on/off switch is provided between energy source and light source.
Claim 9
Dependent Claim
34 words
An ice hockey puck according to claim 4, characterized in that the transparent body is surrounded at the outside of its light emitting surface and the cavity region with a reflecting or fluorescent layer.
