US Patent:

56159013, Apr 1, 1997

Filed:

Nov 2, 1994

Appl. No.:

8/333374

Inventors:

David J. Piotrowski - New York NY

International Classification:

A63C 128

US Classification:

280 714

Abstract:

The adjustable foot equipment is adaptable to ski boots, in-line roller skates, ice skates, water skis and snowboards, and includes a base formed with a depending appendage adapted to be joined with a support member. The appendage and the support member are formed with complementary engaging curved surfaces that permit relative pivotal movement between a foot holding portion of the foot equipment and the support member. Once a desired offset angular orientation between the support member and the foot holding portion is determined, a securing arrangement locks the support member to the appendage. The securing arrangement can be easily released to permit resetting of a selected offset angular orientation. Some embodiments of the invention permit permanent adjustment of a selected offset angular orientation.
