Appl. No.:

11/639394

Inventors:

Gregory Vinton Matthews - San Francisco CA, US
Francis E. Mahoney - Barre VT, US

Assignee:

K-2 Corporation - Seattle WA

International Classification:

A43B 5/04
A43B 5/16

US Classification:

36122, 36124, 36125

Abstract:

A snowshoe having a pivot axle for pitch rotation of the footbed platform relative to the snowshoe frame is supported from the frame in a manner that provides for significant lateral flexing, i. e. pivoting on the roll axis, to accommodate use of snowshoes on side hill terrain. Instead of a relatively rigid support from the snowshoe frame, the footbed platform is supported by left and right tension bands that are connected to the snowshoe frame and to left and right ends of the transverse pivot rod that provides pitch rotation. Preferably the connection to each end of the pivot rod is with a rotatable spindle over which the tension band engages, such rollers being connected at right angles to the two ends of the pivot rod. A rotation limiter can be included to limit free rotation of the binding in the pitch direction to a selected arc. The footbed support system can be employed on any type of snowshoe, whether a tubular frame, non-tubular frame or molded composite snowshoe.
