Description

ta présente invention concerne une fixation à plaque pour ski de fond et de randonnée nordique.Ce dispositif s'incere dans l'ensemble du matériel utilisé par un skieur de fond et de randonnée. Le définition d'un randonneur nordique est un shieur qui évolue sur des terrains ne présentant pas de pentes a fortes denivélation, mais des terrains valonnés dans lesquels le skieur rencontre des pentes et des virages qui sont difficiles a négocier avec des skis de fond. En effet les skis de fond ont des largeures au millieu du ski trés etroites et une souplesse qui accentuent le déséquilibre du skieur,lorsque celui-ci pratique le ski de fond de randonnée en dehors dea pistes préparées. Your present invention relates to a plate binding for cross-country skiing and Nordic touring. This device fits into all the equipment used by a cross-country and touring skier. The definition of a Nordic hiker is a shieur who evolves on terrain that does not have steep slopes, but hilly terrain in which the skier meets slopes and turns that are difficult to negotiate with cross-country skis. In fact, cross-country skis have very narrow widths in the middle of the ski and a flexibility which accentuate the imbalance of the skier, when the latter practices cross-country ski touring outside of the prepared tracks.

Cet ensemble se caractérise par composition,par le fait que l'in- -vention peut recevoir toutes les fixations de fond de marque exietontes, aux normes différentes, utilisées actuellement sur le marché.Cet ensembl, fixation de fond plus plaque de maintient chaussure, offre la possibilité d'être immobilisé sur le ski par un disposif de blocage,dont celui-ci exerce sont role de maintient sans tenir compte de la chaussure. This set is characterized by composition, by the fact that the in-invention can receive all the bottom fasteners of the brand exietontes, with different standards, currently used on the market. offers the possibility of being immobilized on the ski by a blocking device, of which this exercises its role of maintenance without taking account of the boot.

L'idée de sette invention est basée sur trois critéres@
Premirement,permettre au skieur fonder ou randonneur; de concerver le technique de fond néccéssaire pour se propulser et faire glieser ses skis sur la neige. Cette technique consiste à utiliser le mouvement de la marche, en accentuant l'enjambée par le fait de presser le ski sur la neige et de faire glisser les silmutanément.Ce qui se nomme le pas alternatif,ou pas glissé.The idea of this invention is based on three criteria @
First, allow the skier to base or hiker; to keep the background technique necessary to propel yourself and make your skis glide over the snow. This technique consists in using the movement of walking, accentuating the stride by pressing the ski on the snow and sliding the silmutaneously. What is called the alternative step, or not slipped.

Dans se mouvement , la fixation évolue avec le pied,En effet,lorc de la pression du pied arriere sur le ski,le pied flégit au niveau tes métatarses, ce qui entraine naturellement la fléxion de la chaussure. In this movement, the binding evolves with the foot. In fact, when the pressure from the rear foot is pressed against the ski, the foot swells at your metatarsals, which naturally causes the shoe to flex.

Pendant cette phase, la plaque mobile (fig 6e) @uit la choussure.Gette chaussure est maintenue par un disposit quelconqu@s, qui pourrait être une sangle entourant la chaussure ,cet sangle elle même reliée n la à le plaque sur une barette métallique vissée sur la plaque ( fig 2).During this phase, the movable plate (fig 6e) @uit the choussure.Gette shoe is maintained by any disposit @ s, which could be a strap surrounding the shoe, this strap itself connected n la to the plate on a metal barette screwed onto the plate (fig 2).

Dèuxiemement l'invention permet de concerver le matériel existant.Secondly, the invention makes it possible to conserve the existing material.

En effet l'invention se caractérlse par le fait quelle permet d'adapter une fixation de fond ou étrier de fond,sur cette invention ( fig 4-4)
Cette plaque se compose de trois parties principales. Une embase fixe (fig @ ) recevant l'étrier de fond et ayant la même implantation par vis que l'étier de fond. Indeed, the invention is characterized by the fact that it makes it possible to adapt a bottom fixing or bottom bracket, to this invention (fig 4-4)
This plate consists of three main parts. A fixed base (fig @) receiving the bottom bracket and having the same installation by screws as the bottom bracket.

Cette fixation avant maintient le bout de la chaussure immobile.ta deuxieme partie est une plaque mobile ( fig 5 ) qui accompagne la chaussure dans tous les mouvements pré-cités. Cette embase reçoit les 2/3 arrière de la surface de la chaussure.Cette plaque souple par sa matiere qui sera de préférence en matire plastique ( delrin de préférence marque déposée) , est reliée à la premiere plaque fixe par une articula -tion . Cette articulation se caractérise par le fait quelle se place à l'aplomb de la fléxion du pied ,et qu'elle ne doit pas géner l'appui du pied sur le ski, ni la fléxion de la chaussure.This front binding maintains the toe of the shoe immobile.ta second part is a movable plate (fig 5) which accompanies the shoe in all the aforementioned movements. This base receives the rear 2/3 of the surface of the shoe. This flexible plate by its material which will preferably be made of plastic (preferably Delrin registered trademark), is connected to the first fixed plate by an articulation -tion. This articulation is characterized by the fact that it is placed vertically above the flexion of the foot, and that it must not interfere with the support of the foot on the ski, nor the flexion of the boot.

Sur la plaque mobile ( fig 5 ) une raynure ou évidement sera effectué afin d'utiliser un dispositif pour mainténir la chaussure pour ntimporte quelle pointure de chaussure. On the movable plate (fig 5) a stripe or recess will be made in order to use a device to maintain the shoe for any shoe size.

L'articulation ( fig - 6 b ) sera composée de deux plaques charniere, reliées par un axe en inoxidable de préférence. The joint (fig - 6 b) will be composed of two hinge plates, preferably connected by a stainless steel pin.
