Abstract
Abstract A pair of rearwardly controlled snow skis including a relatively rigid weight-bearing rear portion for mounting of ski boots thereon and projecting rearwardly from the boot heel to form a trailing portion terminating in a trailing edge. The skis project forwardly of the boot and have the top and bottom surfaces tapering inwardly toward one another to form a relatively flexible planing portion. The skis also taper outwardly along their opposite edges to form a relatively wide upturned shovel at the front extremity thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
219 words
A pair of rearwardly controlled snow skis for mounting ski bindings thereon for receipt of ski boots, each ski comprising: a relatively rigid weight-bearing rear portion for mounting of said ski bindings to position the boot received therein with the toe and heel over the respective front and rear of said weight-bearing portion, said ski projecting rearwardly to form a trailing portion projecting rearwardly of the heel of said boot a distance no greater than 17% of the overall ski length and terminating in a trailing edge and further projecting forwardly to form a relatively flexible planing portion turned upwardly at its front extremity to form a shovel, the bottom surfaces of said rear and planing portions being substantially flat to facilitate shifting from side-to-side of said ski and having a substantially continuous downwardly facing longitudinal contour; and the top and bottom surfaces of said planing portion tapering gradually and continuously forwardly and inwardly toward one another to form a relatively thick aft-end joined with said weight-bearing portion and narrowing to a relatively thin forward end joined with said shovel, the lateral sides of said ski further tapering inwardly and rearwardly from the width of said shovel to terminate at said trailing portion in a relatively narrow aft-end, the total length of said ski being at least 90 centimeters.
Claim 2
Dependent Claim

A pair of rearwardly controlled snow skis for mounting ski bindings thereon for receipt of ski boots, each ski comprising: a relatively rigid weight-bearing rear portion for mounting of said ski bindings to position the boot received therein with the toe and heel over the respective front and rear of said weight-bearing portion, said ski projecting rearwardly to form a trailing portion projecting rearwardly of the heel of said boot a distance no greater than 17% of the overall ski length and terminating in a trailing edge and further projecting forwardly to form a relatively flexible planing portion turned upwardly at its front extremity to form a shovel, the bottom surfaces of said rear and planing portions being substantially flat to facilitate shifting from side-to-side of said ski and having a substantially continuous downwardly facing longitudinal contour; and the top and bottom surfaces of said planing portion tapering gradually and continuously forwardly and inwardly toward one another to form a relatively thick aft-end joined with said weight-bearing portion and narrowing to a relatively thin forward end joined with said shovel, the lateral sides of said ski further tapering inwardly and rearwardly from the width of said shovel to terminate at said trailing portion in a relatively narrow aft-end, the total length of said ski being at least 90 centimeters.
Claim 3
Dependent Claim
17 words
A pair of skis as set forth in claim 1 wherein: said trailing portion is substantially planar.
Claim 4
Dependent Claim
19 words
A pair of skis as set forth in claim 1 wherein: said ski is at least 9.5 centimeters wide.
Claim 5
Dependent Claim
38 words
A pair of skis as described in claim 1 that includes: binding means including means to dispose the heel of the skier's boot at a predetermined angular elevation above and with respect to the toe of the boot.
Claim 6
Dependent Claim
24 words
A pair of skis as described in claim 4 wherein: the means to elevate the heel of the skier's boot comprises a triangular wedge.
Claim 7
Dependent Claim
24 words
A pair of skis as set forth in claim 1 wherein: said planing portion constitutes at least 35% of the length of said ski.
Claim 8
Dependent Claim
23 words
A pair of skis as set forth in claim 1 wherein: said trailing portion constitutes substantially 17% of the length of said ski.
Claim 9
Dependent Claim
22 words
A pair of skis as set forth in claim 1 wherein: said planing portion constitutes substantially 42.5% of the overall ski length.
Claim 10
Dependent Claim
25 words
A pair of skis as set forth in claim 1 that includes: a wear resistant pressure plate mounted on the underside of said trailing portion.
Claim 11
Dependent Claim
35 words
A pair of skis as described in claim 9 that includes: means for removably mounting said pressure plate so it can be removed and replaced by a differently contoured pressure plate for different snow conditions.
Claim 12
Dependent Claim
34 words
A pair of rearwardly controlled snow skis as set forth in claim 1 wherein: said trailing portion projects rearwardly of said heel a distance no greater than one-third the length of said planing portion.
