FR2561114A1 - Ski boot/binding assembly. Safety assembly for ski, comprising a novel multiple technique of release operations which is integrated onto the ski and into the ski boot - Google Patents

Abstract

The present invention relates to a novel multiple technique of safety release operations, which is composed of two elements 1 and 2, one of the elements having multi-dimensional geometry 3 and being compression multi-directional 4, having the particular feature of being capable of being reversed and being, either one or the other, securely attached to the ski or integrated into the ski boot. By virtue of a progressive compression adjustment, the multi-directional element 4 is integrated into a solid with multi-dimensional geometry 3, enabling it, under the action of exterior forces, to be disengaged by one of the meridians 5 of a hemisphere, these disengagements corresponding to a range of 0 to 180 DEG .

Description

DESCRIPTION
The object of the invention consists mainly 1 "- in the creation of a solid in high resistance materials, with poly-dimensional geometry receiving a polydirectional solid 2" - to allow this assembly to reverse and, indifferently, to s 'to integrate :
a) multi-dimensional on the ski and multi-directional in the boot
b) the multi-dimensional in, the shoe and the multi-directional on the ski
For acilit, we present the example of a multidimensional shoe.

The object of the invention is characterized by the means used, taken both as a whole and separately and, more particularly 1 "- by the manufacture of a molded shoe, factory or mold-machined in which 's '' integrated in the rear, front, or front and rear, a multi-directional or multi-dimensional safety system.

This multi-dimensional can have been made at the same time as the hoof or separately, and come to be integrated in a recess previously arranged to receive it. I1 can have a groove for fitting skis with all traditional bindings.

The materials, qualities, quantities of agents used for the creation of this set, may vary within the limit of the equivalents which can be used, without thereby changing the general conception of the invention which has just been described.

Also, this shoe-binding invention can be made as well in nylon, polyamide, steel or aluminum and cannot be limiting in the choice of materials and the technical progress that the inventor could bring to it.

This design, unlike what has been done until now, combines both postero-anterior, lateral and diagonal safety clearances, in a range from O to 1800.

20 - by the angle of the polydirectional and its positioning behind the skier's center of gravity. This angle is located, specifically, where the effects are greatest and the most favorable opening angles.

Consequently, this multi-trip avoids or limits the greatest number of traumas caused by lateral-posterior forces and the diagonal tensions exerted on the lower limb.

This innovation has, therefore, a considerable advantage over current bindings which act only in the lateral directions at the front and only vertical at the rear.

SYNTHESIS
Obviousness is at the origin of the design of this safety, knowing that: 1 "- that the front fall, the fall before torsion and the torsion fall represent approximately 80% of the cases of tearing efforts of the skis of the feet skiers, causing the separation of the skis from the boots.

20 - that these basic antero-posterior, vertical or lateral forces slow down the movement of the skis relative to the skier 3 - that therefore the forward, vertical, lateral or diagonal projection of the skier's body displaces its center of gravity by front 4 "- that the real support points of the plane of the foot at the time of the anterior, lateral, diagonal or vertical projections are no longer on the rear of the support polygon, but in an area formed by the front 1/3 of the shoe.

 50 - that thus, it is obvious that the axes of rotation and of support are very close to the front stop and, consequently, that the greatest angle of vertical, diagonal or lateral displacement is located on the back of the shoe.

These observations force us to admit that, as a priority, the safety releases must be at the rear and multidirectional and that the front safety features are only complementary.

DEFINITION OF ELEMENTS OF FOOTWEAR-FIXATION-SKI
MULTIDIMENSIONAL
Solid with multi-dimensional geometry and concave action surfaces, in resistant, injected, machined or injected-machined material.

Half-sphere whose circumferencg presents a variable circular spherical trigonometry whose arcs correspond to vertices of truncated semi-cones, each having values of different angles but preserving the symmetry of the circumference of the sphere which remains constant.

This spherical trigonometry could also translate into revolutions in the half-sphere of the 3 meridians with offset poles, with respect to each other.

Seen from the front, this solid has the following geometrical characteristics - in its approximate center, a concave half-sphere receives, by means of a truncated concave vertical semi-cone, a solid of approximately identical volume - this vertical semi-cone truncated concave whose apex would plunge into the concave hemisphere, also allows the vertical escape of this intake solid - laterally to the right and left of the concave semi-sphere, there are two truncated concave semi-cones, also at vertices dipping into the concave semi-sphere, allowing the lateral and diagonal escapes of the intake solid - the circular trigonometry of the circumference of the concave hemisphere is calculated so that the meridian arcs of triggers or escapements are in constant relationship with the different resistances desired.

POLYDIRECTIONAL
This convex compression solid, of semi-spherical shape (in our example), with more or less elongated body and stop on this body, can be actuated by any single or multiple systems, using either as pushing force or traction, springs, elastics, pneumatic, oleopneumatic techniques, etc ... as soon as the principle remains in its design: that is to say, repel this solid, with the possibility of progressive adjustment of its compression, whatever are the principle and the position in the multi-dimensional concave cavity which must receive it to create the homogeneity of the whole.

The example taken is not limiting in its forms or its action: this poly-directional can therefore be spherical, ovotid, helliptic, etc. fixed or rotary, without this changing the characteristics of the invention.

This mechanical assembly, taken in a single piece can, like the multidimensional, be integrated into the boot or integral with the ski.

This homogeneous shoe-binding-ski set, with multidirectional clearances is therefore characterized by the elements - independently of a conventional front stop or not, acting as force locking in the posterior anterior direction, to bring a ski piece into a piece of shoe, or vice versa, and to maintain the assembly effectively until an external tearing force separates them 10 - the main object of the invention consists, in the case taken as an example, of a hard element (X) multi-dimensional concave, injected, factory, or injected-machined, which revises a multi-directional element, type jack, identical in shape to one of the multi-dimensions, in order to immobilize the boot on the ski.

This multi-dimensional element forming part of the shoe, allows all the triggers during the efforts exerted on the anatomy of the skier, avoiding your creation of trauma by its multidirectional effects.

thanks to the reception of a polydirectional compression element with elastic safety tolerance.

 20 - This safety group, which can be integrated into both the boot and the ski, can either be reversed without modifying, in any way, the set of triggers which take place from O to 1800 in the lateral, vertical directions and diagonals.

 3 - This assembly, located by priority at the rear part of the shoe, presents a significant increase in safety since in the privileged and anatomically favorable trigger zone as the synthesis proves it to us.

 40 - It is good to specify that it is not necessary that the poly-dimensional and the poly-directional compression, in particular the admission element, are machined from the same material, but for the sake of after-sales, it can be envisaged that the multidimensional is integrated into its support with the greatest ease of exchange.
