Generation of in-line skates and skate-boards with safety “edging friction control™”
First Claim
1. A spherical bearing assembly comprising:
- an inner ring member defining a vertical axis and having a bore extending in a direction transverse with respect to the vertical axis;
an outer ring member mounted with respect to the inner ring to permit inclined rotation of outer ring with respect to the vertical axis; and
, a spring structure constructed and arranged to bias the outer ring 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.

4. A wheeled device comprising:
-
a wheel frame;
at least one wheel mounted on an axle associated with the wheel frame;
wherein said wheel is constructed and arranged to rotate around said axle with respect to a vertical axis and at inclinations in apposing directions about the vertical axis and spring structure constructed and arranged to bias the wheel in opposing directions toward the vertical axis. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A wheeled device comprising:
-
a wheel frame;
at least one wheel mounted on an axle for rotation with respect to the wheel frame;
the axle including friction contact surfaces;
the wheel including friction control surfaces; and
,wherein the at least one wheel is constructed and arranged to rotate around the axle both vertically and at an inclination, such that when the wheel is at a certain inclination, the friction control surfaces of said wheel engage the friction contact surfaces of said axle to cause slowing down and braking of said wheel. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
