Abstract

A dry land ski assembly, having forward and rear wheels, includes a foot harness assembly pivotal by body action of the user from a free wheeling to a restricted rotation position for the front wheels.

1. A dry land ski, usable in pairs by a user, comprising a frame member;

a front wheel set journaled for rotation at the front of said frame member and a rear wheel set journaled for rotation at the rear of said frame member;

foot harness means arranged on said frame member intermediate said front and rear wheels inclusive of a toe plate, toe holder attached thereto and heel holding means;

said foot harness means being pivotally mounted so as to pivot from a generally horizontal position downwardly toward said front wheel set;

said toe plate being pivotally mounted in said foot harness means permitting pivoting thereof on upward and downward movement of the user'"'"''"'"'s heel; and

brake means mounted on said foot harness means positioned to contact said front wheel set when said foot harness means is pivoted downwardly for preventing rotation of said front wheel set.

2. A dry land ski according to claim 1 wherein said frame member includes a pair of opposed side frame members.

3. A dry land ski according to claim 2 wherein a cross member between said pair of opposed side frames provides a heel rest for a generally horizontal foot position.

4. A dry land ski according to claim 1 wherein said front and rear wheel sets are formed of at least two wheels each, and each set being journalleD on a single shaft.
