Abstract

Abstract An improved connector releasably secures the ends of a ski training rod to a pair of skis. The connector includes heads on the ends of the rod adjacent shank portions of the rod and an elastomeric receptacle on each ski to receive the head and shank ends of the rod. The receptacle has a hollow interior and its upper region has a gripping sleeve with a through opening approximatley the diameter of the shank and extending downward into the hollow interior of the receptacle. The head of the rod can be forced down through the opening to interlock with the bottom of the sleeve and can be pulled straight up through the opening, but in use, the receptacle holds the shank securely and resists any force tending to alter the distance between the other end of the rod and the receptacle, even as the shank inclines relative to the receptacle.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 238 words
In a ski-training device having a U-shaped rod with headed ends for movably connecting a pair of skis, an improved connector for releasably securing the head ends of said rod to each of said skis, said improved connector comprising: a. a receptacle formed of a single piece of elastomeric material mounted on top of each of said skis; b. said receptacle having an outside wall, a top and a hollow interior; c. the upper region of said receptacle having a gripping sleeve with a through opening approximately the size of the shank of said rod adjacent said head; d. said gripping sleeve extending from said top of said receptacle downward a substantial distance into said hollow interior of said receptacle; e. said head being insertable in said sleeve to interlock with the lower end of said sleeve so said shank is retained in said receptacle and said receptacle resists any force tending to alter thE distance between the other end of said rod and said receptacle; f. said outside wall, top and sleeve of said receptacle being sufficiently deformable so said shank can tilt through a substantial range of angles as said skis move relative to each other with said head remaining interlocked with said sleeve throughout said range of angles; and g. said hollow interior extending around said sleeve to afford clearance for said head to move up under said top as said sleeve and shank tilt.
Claim 2
Dependent Claim 238 words
In a ski-training device having a U-shaped rod with headed ends for movably connecting a pair of skis, an improved connector for releasably securing the head ends of said rod to each of said skis, said improved connector comprising: a. a receptacle formed of a single piece of elastomeric material mounted on top of each of said skis; b. said receptacle having an outside wall, a top and a hollow interior; c. the upper region of said receptacle having a gripping sleeve with a through opening approximately the size of the shank of said rod adjacent said head; d. said gripping sleeve extending from said top of said receptacle downward a substantial distance into said hollow interior of said receptacle; e. said head being insertable in said sleeve to interlock with the lower end of said sleeve so said shank is retained in said receptacle and said receptacle resists any force tending to alter thE distance between the other end of said rod and said receptacle; f. said outside wall, top and sleeve of said receptacle being sufficiently deformable so said shank can tilt through a substantial range of angles as said skis move relative to each other with said head remaining interlocked with said sleeve throughout said range of angles; and g. said hollow interior extending around said sleeve to afford clearance for said head to move up under said top as said sleeve and shank tilt.
Claim 3
Dependent Claim 13 words
The connector of claim 1 wherein said receptacle is formed of solid polyurethane.
Claim 4
Dependent Claim 18 words
The connector of claim 1 wherein said head is formed as a planar annulus concentric with said shank.
Claim 5
Dependent Claim 25 words

Claim 6
Dependent Claim 16 words
The connector of claim 1 wherein said receptacle is mounted on bindings secured to said skis.
Claim 7
Dependent Claim 12 words
The connector of claim 1 wherein said shank has a downward taper.
Claim 8
Dependent Claim 29 words
The connector of claim 1 wherein said lower region of said gripping sleeve extending into said hollow interior is tapered down to said lower end of said gripping sleeve.
Claim 9
Dependent Claim 31 words
The connector of claim 1 wherein said head is formed as a planar annulus concentric with said shank and having a diameter larger than said lower end of said gripping sleeve.
Claim 10
Dependent Claim 13 words
The connector of claim 8 wherein said receptacle is formed of solid polyurethane.
Claim 11
Dependent Claim 29 words
The connector of claim 9 wherein said lower region of said gripping sleeve extending into said hollow interior is tapered down to said lower end of said gripping sleeve.
