Definitions

• the invention relates to shoes intended to be used for sporting practices, in association with a gliding device, for example for sports on snow or ice, skiing, or with a rolling device, for example inline skating. when the shoe part does not form a whole with the machine.
• a gliding device for example for sports on snow or ice, skiing, or with a rolling device, for example inline skating.
• the shoe part does not form a whole with the machine.
• the term “sliding device” will be used to mean both strictly sliding devices and those fitted with wheels.
• the shoe is made integral with the machine during practice, with supports allowing the sportsman to guide his machine and means of restraint to keep the feet on the machine.
• the ski boot being compliant when it is placed on the market with the requirements of the standards, the skier may think that his equipment always remains efficient and reliable. However, after a few hours of use in motion, the quality of the sole / binding connection can be greatly degraded. There are many reasons: snow wedge under the boot when the ski is put on, dirt and encrustations in the sole, degradation of the normalized areas due to wear due to walking, poor induced adjustment, ... etc.
• the shoe / binding assembly must make it possible to transmit the forces from the skier to the ski.
• the polygon formed by the shoe / binding contact zones is of such dimension, that associated with a worn sole and curved by the step, the whole lends itself to a "hinge effect" due to the curved , all the more important as the setting of the fixing is low.
• the first consists in compensating for the deterioration of the normalized surfaces of the shoe by a reduction in the relative movement between the binding and the shoe or by mechanisms creating punctual laxities of the stop, avoiding the effects of "jamming" therefore increasing values trigger.
• These solutions have little effect in the presence of increased wear of the sole due to walking and / or penalize the transmission of the efforts of the skier to the ski by installing an elasticity "clipping" these efforts and accentuating the "hinge effect".
• Another disadvantage is that this technique can be the cause of nuisance trips by offering a too low trigger value in certain configurations of falls not listed by the standards. The user is still tempted to increase the adjustment of his bindings, which ruins the effort of optimization of the adjustment by the manufacturer and puts him himself in a dangerous situation.
• the second axis consists in proposing so-called "plate” fixings. Two concepts have emerged in this area, namely the plates integral with the boot when the trigger and those remaining integral with the ski in the same circumstances.
• the seconds were gradually called "shoes / bindings".
• the plate part integral with the ski and generally comprising the release system, cooperates with specific shapes integrated into the sole of the boot.
• the relationship between the dimensions of the plate and the sole indeed, if the size of the plate is small enough to accommodate small sizes while preserving the standardized ends, it follows especially in large sizes a very disturbed longitudinal stability as long as the sole is raised relative to the ski. In this case, the elasticity of the binding helping, the trigger values will vary depending on the support of the ends of the sole on the ski, varying according to the sizes and the presence or not of snow wedge,
• Ski boots are also known, the shell of which has, at its lower part, profiled notches intended for the front and rear fixing of said shell relative to a rotary plate.
