Abstract
An apparatus for attachment to skis to assist the user to learn basic maneuvers. A bracket is pivotally connected between the front ends of the skis in such a manner that the rear ends thereof can move inwardly and outwardly, and the skis can pivot about their longitudinal axes. A vertical pole is pivotally attached to each ski at a point between the front bracket and the boot retaining means. A connecting rod is pivotally connected between the poles.
Claims6
An apparatus for use with a pair of skis, the combination comprising
- brace means connected between the front ends of said skis for maintaining a given distance between the connected points while permitting the rear portions of said skis to assume positions whereby the distance therebetween is equal to, greater than or less than said given distance and also permitting said skis to pivot about their longitudinal axes,
- means of each of said skis for retaining a foot of one skiing thereon,
- two vertical poles, each having a ski attachment end and a gripping end, the ski attachment end of each pole being attached to a respective one of said skis at a point between said means for retaining and the point of attachment of said brace means, and
- a linkage rod, each end of which is pivotally connected to one of said vertical poles, so that the rear portions of said skis become separated when said gripping ends of said two vertical poles are moved toward each other.

- brace means connected between the front ends of said skis for maintaining a given distance between the connected points while permitting the rear portions of said skis to assume positions whereby the distance therebetween is equal to, greater than or less than said given distance and also permitting said skis to pivot about their longitudinal axes, said brace means comprising two L-shaped brackets each having a base that is pivotally connected to a respective one of said skis, and a brace pivotally connected at each end thereof to one of said brackets, the central portion of said brace extending upwardly above said skis,
- means on each of said skis for retaining a foot of one skiing thereon,
- two vertical poles, an end of each being connected to a respective one of said skis at a point between said means for retaining and the point of attachment of said brace means, said poles being connected to said skis by pivot means for permitting said poles to move limited distances forward and backward, said pivot means comprising a bracket having a U-shaped cross-section, the bottom of each pole having a flanged end which is pivotally connected to the opposing walls of said bracket, the bottom surface of said flanged end contacting the bottom of said bracket when said pole moves predetermined distances forward or backward, and
- a linkage rod, each end of which is pivotally connected to one of said vertical poles.
