Filed:

Feb 9, 2007

Appl. No.:

11/673068

Inventors:

John A. Roderick - Scituate RI, US
David R. Willis - Wakefield RI, US

Assignee:

MEARTHANE PRODUCTS CORPORATION - Cranston RI

International Classification:

A63C 17/22

US Classification:

301 5307

Abstract:

A skate wheel for an in-line skate has a skate wheel hub with an inner hub, an outer rim, and a plurality of blade-form spokes extending therebetween, and a skate tire mounted upon an outer surface of the skate wheel hub. Opposed surfaces of adjacent spokes, in cooperation with opposed surfaces of the inner hub and outer rim, define airflow passageways through the skate wheel. Each blade-form spoke has a radially-aligned first spoke-edge surface exposed at a first face of the skate wheel, a radially aligned opposite, second spoke-edge surface exposed at an opposite, second face of the skate wheel, and a blade-form body extending smoothly therebetween. The first and second spoke-edge surfaces are offset in a direction of travel of the skater by a predetermined arc of rotation of the skate wheel and hub. Also described are in-line skates with skate wheels of the disclosure, and skate wheel hubs for such skates.

US Classification:

301 5307, 301 5301

Abstract:

A skate wheel for an in-line skate includes a skate wheel hub having an inner hub, an outer rim, and, extending therebetween, a plurality of blade-form spokes. A skate tire is mounted upon an outer surface of the outer rim of the skate wheel hub. Opposed surfaces of adjacent blade-form spokes, in cooperation with opposed surfaces of the inner hub and the outer rim, define airflow passageways through the skate wheel. Each blade-form spoke includes a radially-aligned first spoke-edge surface exposed at a skate wheel face, a radially aligned opposite, second spoke-edge surface exposed in a region of a center plane defined by the skate wheel, and a body extending smoothly between the first and second spoke-edge surfaces. Also described are in-line skates with skate wheels of the disclosure, and skate wheel hubs for such skates.

Appl. No.:

9/148589

Inventors:

John A. Roderick - Scituate RI
David R. Willis - Wakefield RI

Assignee:

Mearthane Products Corporation - Cranston RI

International Classification:

A63C 1706

US Classification:

280843

Abstract:

An in-line wheeled skate which includes one or more rollers located between the wheels and above the ground plane, thereby enabling the skater to jump up on a rail (or other supporting surface) and roll down the rail sideways, as in `extreme skating` maneuvers, by placing the skate on the rail with the rollers bearing upon the rail surface. The rollers may be, for example, cylindrical or spherical, and are preferably located between left and right side planes of the skate wheels.

Assignee:

Mearthane Products Corporation

International Classification:

A63C 1706

US Classification:

280 1122

Abstract:

An in-line wheeled skate which includes a rolling element between the wheels that enables the skater to jump up on a rail and roll down the rail sideways, as in `extreme skating` maneuvers, by placing the skate on the rail with the rolling element bearing upon the rail surface. Adjustable brakes provide control of the speed of sideways motion. The rolling element is provided as part of an attachment or lower structure to be secured to an in-line skate.
