Abstract

Abstract Ski training apparatus is provided which includes a base, and a pair of spaced and parallel horizontal bars supported on the base and displaced upwardly from the plane thereof in uniplanar relationship, and a third horizontal bar extending perpendicular to and traversing the pair of bars supported on the base and displaced up from the pair of bars. A first bushing is slidably supported on the third bar, and a pair of bushings are slidably supported on the pair of bars. An intermediate block is mounted between the pair of bushings, and it is pivotally coupled to the bushings for rotation about an axis perpendicular to the axes of the pair of bars. A pair of ski-like boards are pivotally mounted at their front ends on the first bushing in spaced uniplanar relationship. A compression spring is mounted on the pivotal block, and it extends upwardly from the plane of the pair of bars, and a horizontal transverse strip member is mounted on the upper end of the spring, and it extends parallel to the second bar. Finally, the ski-like boards are pivotally mounted at their rear ends to the transverse strip member. Ski harness is mounted on the ski-like boards in position such that the heels of the skier are directly over the transverse strip member.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 110 words
Ski training apparatus comprising: a base; a pair of spaced and parallel horizontal bars supported on the base; a third horizontal bar supported on the base perpendicular to said pair of bars and displaced upwardly therefrom and extending thereacross; first bushing means slidably mounted on said pair of bars; second bushing means slidably mounted on said third bar; a compression spring coupled to said first bushing means and extending upwardly therefrom; and a pair of ski-like boards pivotally mounted at their forward ends to said second bushing means and pivotally mounted at their rear ends to said compression spring, said ski-like boards being held in spaced and parallel uni-planar relationship.
Claim 2
Dependent Claim 110 words
Ski training apparatus comprising: a base; a pair of spaced and parallel horizontal bars supported on the base; a third horizontal bar supported on the base perpendicular to said pair of bars and displaced upwardly therefrom and extending thereacross; first bushing means slidably mounted on said pair of bars; second bushing means slidably mounted on said third bar; a compression spring coupled to said first bushing means and extending upwardly therefrom; and a pair of ski-like boards pivotally mounted at their forward ends to said second bushing means and pivotally mounted at their rear ends to said compression spring, said ski-like boards being held in spaced and parallel uni-planar relationship.
Claim 3
Dependent Claim 71 words
The ski training apparatus defined in claim 1, in which said first bushing means comprises a pair of bushings respectively slidably mounted on said pair of bars, and which includes a block interposed between said pair of bushings and pivotally coupled thereto for angular movement about an axis parallel to the axis of said third bar, and in which said compression spring is mounted at its lower end on said block.
Claim 4
Dependent Claim 37 words
The ski training apparatus defined in claim 2, and which includes an elongated strip member mounted on the top of said compression spring, said ski-like boards being pivotally coupled at their rear ends to said strip member.
Claim 5
Dependent Claim 34 words
The ski training apparatus defined in claim 3, and which includes ski harness mounted on each of said ski-like boards in position to hold the heels of the skier directly over said strip member.
