A limb protector comprising a knee element. In a preferred embodiment the knee element is pivotally coupled to an outer shell shin element. Padding is positioned between the leg and the outer shell(s) and may be formed of a shock absorbent foam, a plurality of interconnected fluid filled cushions, or a combination thereof. The padding may be coupled to the outer shell shin element so as to create a gap between itself and the outer shell shin element. Alternatively, the padding may positioned on the lateral and medial sides of the outer shell knee element to cradle the underlying leg. The outer shell shin element comprises a raised groove element protruding outward from the shin to form a shin-knee transition cavity located between the shin-knee transition of the leg and the outer shell shin element. The outer shell knee element comprises a centrally positioned domed element protruding outward from the knee generally overlying the patella and may also overlie the shin-knee transition area. The outer shell knee element may also have a tongue element extending downward toward the ankle so as to interlock within the raised groove element. The padding element may comprise a U-shaped opening positioned underneath the raised groove and above the shin-knee transition of the leg and an elongated flange element in overlapping configuration with a portion of the padding that is located below the U-shaped opening. The padding element and the outer shell element(s) are configured so that the shin-knee transition area and the patella do not absorb force.

Set of in-line wheels

This invention relates to a thumb protector for a protective athletic glove, such as used in hockey, lacrosse, and motorcycle racing. The thumb protector involves two elements secured dorsally to the thumb stall and thumb receiving area of the glove, which cooperate to allow opposable thumb movement while still providing superior protection against external blows and injury due to hyper-extension and over-extension. As another aspect of the invention, the thumb-piece of the thumb protector is ergonomically configured to approximate the contour the metacarpalphalangeal joint will typically assume when the wearer is lightly gripping an athletic stick or handlebar.

A roller skate wheel is described wherein the weight of wheel is significantly reduced by employing a bushing bearing instead of the usual ball bearing in at least one side of the wheel. The bushing is formed of Peek material so as to provide the necessary strength and low friction necessary to provide desirable skating characteristics.

Wheels for inline roller skates

An inline roller skate includes a large number of small, light weight wheels arranged along a downwardly convex arcuate line to form a rocker. Braking elements are disposed along a common axis with at least some of the wheels, the braking elements may take the form of various surfaces of revolution, such as conical, cylindrical, ellipsoidal or semispherical. The braking elements are arranged to contact the skating surface when the skater shifts his foot to a direction perpendicular to his direction of movement and leans back on his skate so as to perform an 'ice skating' type braking action.

Inline hockey skate

An inline hockey roller skate and wheel which includes braking and tread elements. The two elements have surfaces formed of a tough resilient material, such as urethane, disposed over a strong cage like frame. The frame and the tough resilient material provide a tread element which is a relatively hard surface so as to provide a fast wheel. The tread element is formed with an air chamber in the tough resilient material so as to be more easily deformable during the braking action. The braking element is arranged to contact the skating surface when the skater shifts his foot to a direction perpendicular to his direction of movement and leans back on his skate so as to perform an 'ice skating' type braking action. The braking element is thus deformed and flattened against the skating surface to provide a larger foot print to improve gripping the surface for better cornering and ice hockey type stops.
