Abstract
Abstract ABSTRACT OF THE DISCLOSURE A system for binding a boot to a ski comprises a connection allowing the lift of the heel of said boot from the top surface of the ski. Means for laterally holding the boot on the ski extend substan-tially longitudinally with respect to said boot, at least in the zone located beneath the front thereof. One part of said lateral holding means is located beneath the boot and the other part on the top surface of the ski, two parts comprising sections of comple-mentary shape ensuring their cooperation during all the phases of movement of the foot during the practice of skiing. The sole made of supple, but abrasion-resistant material comprises, in the front zone thereof, at least one groove extending substantially longitudi-nally from the tip of the boot at least up to the metatarsal zone.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
170 words
In a cross-country ski binding system having means on the ski for anchoring the toe portion of the boot to the ski while at the same time permitting the heel of said boot to lift with respect to the top surface of the ski, the improvement comprising means for inhibiting lateral shifting of the boot relative to the length of the ski, said lateral shift inhibiting means including a first part associated with the undersurface of the sole of the boot and a second part associ-ated with the top surface of the ski, said first and second parts including respec-tive recessed and projecting sections of complementary mating shapes extending longitudinally of the ski from adjacent the boot toe-anchoring means in a direction rearwardly therefrom toward the heel of the boot, said complementary mating shapes gradually tapering in a direction from one end toward the other whereby they gra-dually vary in cross-sectional area longitudinally therealong, such that the cross-sectional area at one end is greater than that at the other end.
Claim 2
Dependent Claim
170 words
In a cross-country ski binding system having means on the ski for anchoring the toe portion of the boot to the ski while at the same time permitting the heel of said boot to lift with respect to the top surface of the ski, the improvement comprising means for inhibiting lateral shifting of the boot relative to the length of the ski, said lateral shift inhibiting means including a first part associated with the undersurface of the sole of the boot and a second part associ-ated with the top surface of the ski, said first and second parts including respec-tive recessed and projecting sections of complementary mating shapes extending longitudinally of the ski from adjacent the boot toe-anchoring means in a direction rearwardly therefrom toward the heel of the boot, said complementary mating shapes gradually tapering in a direction from one end toward the other whereby they gra-dually vary in cross-sectional area longitudinally therealong, such that the cross-sectional area at one end is greater than that at the other end.
Claim 3
Dependent Claim
26 words
The improvement as defined in Claim 1, wherein the cross-section of said shapes increases in a direction from the front to the rear of the boot.
Claim 4
Dependent Claim
26 words
The improvement as defined in Claim 1, wherein the cross-section of said shapes decreases in a direction from the front to the rear of the boot.
Claim 5
Dependent Claim
25 words
The improvement as defined in Claim 3, wherein the complementary mating shapes have a cross-section with a decreasing curved surface, running from front to back.
Claim 6
Dependent Claim
23 words
The improvement as defined in Claims 1, 2 or 3, wherein the complemen-tary mating shapes are constituted by portions of a conical frustrum.
Claim 7
Dependent Claim
22 words
The improvement as defined in Claims 1, 2 or 3, wherein the complemen-tary mating shapes are constituted by portions of a pyramid.
Claim 8
Dependent Claim
41 words
The improvement as defined in Claims 1, 2 or 3, wherein the means for laterally holding the boot on the ski extends substantially longitudinally with respect to the boot from the zone under the toe to the zone under the heel.
Claim 9
Dependent Claim
39 words
The improvement as defined in Claim 1, wherein the complementary mating shapes are constituted by the shape of a volume substantially in the form of a portion of a triangular pyramid comprising a small and a large triangular base.
Claim 10
Dependent Claim
22 words
The improvement as defined in Claim 7, wherein the height between the small and large triangular bases of the volume is constant.
Claim 11
Dependent Claim
25 words
The improvement as defined in Claim 7, wherein the height between the small and large triangular bases of the volume varies in the longitudinal direction.
Claim 12
Dependent Claim
31 words
The improvement as defined in Claim 8, 9 or 10, wherein the small and large triangular bases each have the form of an isoceles triangle with the apex facing the front.
Claim 13
Dependent Claim
54 words
The improvement as defined in Claim 8, 9 or 10, wherein the volume projects from the surface of the ski and forms a large triangular base in contact with the upper surface of the ski and a small triangular base facing the sole of the boot presents a recessed volume of the same shape.
Claim 14
Dependent Claim
32 words
The improvement as defined in Claim 1, wherein the com-plementary mating shapes have polygonal cross-sections with at least two sides parallel to each other and perpendicular to the plane of the ski.
Claim 15
Dependent Claim
59 words
The improvement as defined in Claim 12, wherein the sides parallel to each other and perpendicular to the plane of the ski comprise a rectilinear central rib along the longitudinal axis of the boot and on either side of which transverse lateral ribs extend perpendicularly, and wherein the ridges form an acute angle with the plane of the ski.
Claim 16
Dependent Claim
31 words
The improvement as defined in Claim 3, wherein the com-plementary mating shapes have a cross-section in the form of a V and the surface of which decreases from front to rear.
Claim 17
Dependent Claim
21 words
The improvement as defined in Claim 15, wherein the complementary mating shapes are extended rearwardly by rectilinear sections of constant cross-section.
Claim 18
Dependent Claim
40 words
The improvement as defined in Claim 15, wherein the side, having the largest section, of the projecting part having a cross-section decreasing towards the rear is arranged with a bevelled edge which engages in a corresponding groove in the sole.
