Generation of in-line skates and skate-boards wtih safety “edging friction control™”
First Claim
1. A wheel assembly comprising:
- a roller member;
roller bearing structure permitting the roller member to rotate about an axis of rotation and with respect to a vertical axis;
a spherical bearing structure constructed and arranged to permit the roller member to rotate about the axis of rotation at an angle with respect to the vertical axis; and
, spring structure constructed and arranged to bias the roller member towards the vertical axis.

Abstract
The frame of an in-line skate (FIG. 8B) supports a wheel (10), allowing a skater to effectively slow down and stop, using an athletic stance that skiers on snow and ice skaters on ice use. The wheel (10) has a hub (20A), allowing a wheel to rotate around the axle (13A) vertically and at an inclination. The hub has axle roller bearings (23B). The wheel (10) includes friction band surfaces (11A) on the sides of the wheel. When rotating at an inclination the wheel'"'"'s friction surface contacts a friction surface (11B), inside the wheel-well or an axle friction surface or a combination thereof to slow or brake the wheel. The wheel (10) assembly includes self-aligning springs (14A/B). Individual parts can be technically designed to allow various model solutions that will satisfy the abilities of a beginner to an expert. The wheel assembly frame can be attached to an in-line skate, an in-line skateboard, a downhill in-line ski and a downhill in-line skateboard.
