Abstract

An in-line skate wheel assembly for a skate mounted speedometer or odometer 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.

Claims

1. A wheel assembly for an in-line roller skate adapted to be used in conjunction with a skate carried speedometer or odometer assembly, including a central hub carrying a bearing, a Shore A durometer elastomer carried by the hub having an outer tread surface. and a magnet embedded in the elastomer in a position where its magnetic field passes outwardly from the elastomer, said magnet having a threaded portion so the magnet can be threaded into the elastomer.

2. A wheel assembly for an in-line roller skate adapted to be used in conjunction with a skate carried sensor, comprising:

a wheel assembly having a periphery, and a sensing element mounted on the wheel assembly near the periphery thereof in a position to be sensed by the skate sensor, said sensing element including a magnet, and the wheel assembly including an elastomeric tire, said magnet being embedded in the tire, said magnet having a threaded portion so the magnet can be threaded into the elastomer.

3. A wheel assembly for an in-line roller skate as defined in claim 2, wherein the magnet is inserted into a hole in the side of the elastomer parallel to the axis of the wheel assembly.

4. A wheel assembly for an in-line roller skate as defined in claim 2, wherein the magnet is inserted into a hole in the tread surface of the elastomer in a generally radial direction.
