Speedometer or odometer assembly for in-line skate
First Claim
1. A speedometer or odometer assembly for an in-line roller skate of the type having a shoe frame having a toe portion including an upper surface and a lower surface supported on a downwardly projecting wheel frame rotatably supporting a plurality of wheels in a generally common plane including a forward wheel having a tread portion adjacent the toe portion lower surface, comprising:
- a speedometer or odometer assembly mounted on the toe portion upper surface including a signal processor adapted to process signals representing skate speed, display driving circuitry responsive to the signal processor and a digital display facing generally upwardly so it can be read by the skater, a sensor mounted on the toe portion lower surface directly adjacent the forward wheel, connected by short conductor means to the signal processor, and a discrete sensing element carried by the forward wheel tread portion in a position to pass in close proximity to the sensor as the forward wheel rotates.

Abstract
A speedometer or odometer assembly for an in-line skate that includes a signal processor and display housing mounted on the skate toe with a sensor mounted under the toe very close to the forward wheel. A field producing sensing element is fixed in the elastomeric portion of the forward wheel where it passes in close proximity to the sensor as the wheel rotates. The display housing is connected to the sensor by a flat conductor and the three are quickly removable as a unit from the skate.

5. A speedometer or odometer assembly for an inline roller skate of the type having a shoe frame having a toe portion including an upper surface and a lower surface supported on a downwardly projecting wheel frame rotatably supporting a plurality of wheels in a generally common plane including a forward wheel adjacent the toe portion lower surface, comprising:
- a speedometer or odometer assembly mounted on the toe portion upper surface including a signal processor adapted to process signals representing skate speed, display driving circuitry responsive to the signal processor and a digital display facing generally upwardly so it can be read by the skater, a Sensor mounted on one of the frames in close proximity to one of the skate wheels, electronically connected to the signal processor, and a discrete sensory element carried by one of the wheels in close proximity to the sensor as the one wheel rotates past the sensor, said sensing element being carried in a radially outward position on the one wheel, said sensor being mounted on said one frame radially outward from the one wheel, and means to adjust the position of the sensor radially inwardly with respect to the one wheel as the wheel wears to maintain sensing effectiveness.

8. A speedometer or odometer assembly for an in-line roller skate of the type having a shoe frame having a toe portion including an upper surface and a lower surface supported on a downwardly projecting wheel frame rotatably supporting a plurality of wheels in a generally common plane including a forward wheel adjacent the toe portion lower surface, comprising:
- a speedometer or odometer signal receiving assembly mounted on the toe portion upper surface including a signal processor adapted to process signals representing skate speed for a digital display, a sensor mounted on the toe portion lower surface directly adjacent the forward wheel, connected by short conductor means to the signal processor, and a discrete sensing element carried by the forward wheel in a position to pass in close proximity to the sensor as the forward wheel rotates.
