Abstract
Abstract A roller skate attachment operable to be fitted onto a roller skate having a shoe upper, a sole, a running gear attached to the sole and a toe stop releasably connected to a forward portion of the running gear. The attachment comprises a plurality of light emitting diodes releasably connected to the toe stop. A battery is operably mounted on the roller skate and an electrical circuit selectively interconnects the battery and the light emitting diodes to selectively light the diodes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
A roller skate attachment operable to be fitted onto a roller skate having a shoe upper, a shoe sole, a running gear connected to the shoe sole and a toe stop releasably connected to a generally forward portion of the running gear, said roller skate attachment comprising: toroidal shaped disc means releasably connected to a toe stop of the roller skate; a plurality of light emitting diodes embedded within said toroidal shaped disc and being radially directed outwardly from the center of said disc said toroidal disc means being fabricated from a material which will permit said plurality of light emitting diodes to be visually detected through the disc material; battery means operable to be connected to said roller skate; and circuit means interconnecting said battery means and said plurality of light emitting diodes for selectively transmitting current to actuate said light emitting diodes.
Claim 2
Dependent Claim
144 words
A roller skate attachment operable to be fitted onto a roller skate having a shoe upper, a shoe sole, a running gear connected to the shoe sole and a toe stop releasably connected to a generally forward portion of the running gear, said roller skate attachment comprising: toroidal shaped disc means releasably connected to a toe stop of the roller skate; a plurality of light emitting diodes embedded within said toroidal shaped disc and being radially directed outwardly from the center of said disc said toroidal disc means being fabricated from a material which will permit said plurality of light emitting diodes to be visually detected through the disc material; battery means operable to be connected to said roller skate; and circuit means interconnecting said battery means and said plurality of light emitting diodes for selectively transmitting current to actuate said light emitting diodes.
Claim 3
Dependent Claim
91 words
A roller skate attachment operable to be fitted onto a roller skate as defined in claim 1 wherein said toroidal shaped disc means comprises: a transparent disc shaped torus operable to hold said plurality of light emitting diodes in a regularly spaced, peripheral ring, radially directed away from the center of said transparent disc, said disc shaped torus having an external diameter substantially equal to the diameter of the toe stop and being operable to fit between the top of the toe stop and the running gear of the roller skate.
Claim 4
Dependent Claim
89 words
A roller skate attachment operable to be fitted onto a roller skate as defined in claim 1 wherein said toroidal shaped disc means comprises: a translucent disc shaped torus operable to hold said plurality of light emitting diodes in a regularly spaced, peripheral ring, radially directed away from the center of said translucent disc shaped torus having an external diameter substantially equal to the diameter of the toe stop and being operable to fit between the top of the toe stop and the running gear of the roller skate.
Claim 5
Dependent Claim
40 words
A roller skate attachment operable to be fitted onto a roller skate as defined in claim 1 wherein said circuit means comprises: means for blinking said plurality of light emitting diodes on and off in unison at a predetermined frequency.
Claim 6
Dependent Claim
48 words
A roller skate attachment operable to be fitted onto a roller skate as defined in claim 1 wherein said circuit means comprises: means for supplying current to said plurality of light emitting diode means in sequence for producing sequential blinking of said plurality of light emitting diode means.
Claim 7
Dependent Claim
46 words
A roller skate attachment operable to be fitted onto a roller skate as defined in claim 1 wherein said circuit means comprises: acoustic transducer means and detector/pulse generator means for blinking said light emitting diode means in response to audio signals received by said acoustic transducer.
