Description détaillée de l'inventionDetailed description of the invention

En référence aux figures 1 et 2, un crampon à glace 10 est composé d'une partie antérieure ou tête 11, et d'une partie postérieure ou talon 12, les deux parties pouvant s'adapter à une semelle d'une chaussure d'alpiniste. La tête 11 et le talon 12 sont formés par des pièces indépendantes, chacune étant ajourée dans sa partie centrale, et réalisées en un matériau métallique, notamment en aluminium ou en acier. A la périphérie de la tête 11 et du talon 12, s'étendent une pluralité de dents 13 pointues destinées à pénétrer dans la pente de glace ou de neige dure. Toutes les dents 13 sont orientées vers le bas, sauf les deux pointes horizontales à l'avant de la tête 11.With reference to figures 1 and 2 , an ice crampon 10 is composed of an anterior part or head 11, and a rear part or heel 12, the two parts being able to adapt to a sole of a mountaineer's shoe. The head 11 and the heel 12 are formed by independent parts, each being pierced in its central part, and made of a metallic material, in particular aluminum or steel. At the periphery of the head 11 and the heel 12 extend a plurality of pointed teeth 13 intended to penetrate the ice slope. or hard snow. All the teeth 13 are oriented downwards, except the two horizontal points at the front of the head 11.

Un premier étrier 14 de fixation en forme d'arceau est articulé transversalement à l'avant de la tête 11 pour venir en engagement avec le rebord avant de la semelle de la chaussure. Au talon 12 est articulé un deuxième étrier 15 en forme de U sur lequel est montée une talonnière 16 pour le blocage du rebord arrière de la semelle. Le deuxième étrier 15 en U est plus grand que le premier étrier 14, et ses deux extrémités sont logées de part et d'autre du talon dans l'un des trous 17 prévus dans les deux dents antérieures du talon 12. Les extrémités du premier étrier 14 peuvent également être insérées dans l'un des trous 18 espacés ménagés dans les dents 13 latérales de la tête 11.A first bracket-shaped bracket 14 is hinged transversely to the front of the head 11 to engage with the front flange of the sole of the boot. At the heel 12 is articulated a second U-shaped stirrup 15 on which is mounted a heel 16 for locking the rear flange of the sole. The second stirrup 15 U is larger than the first stirrup 14, and its two ends are housed on either side of the heel in one of the holes 17 provided in the two anterior teeth of the heel 12. The ends of the first stirrup 14 may also be inserted into one of the spaced holes 18 formed in the lateral teeth 13 of the head 11.

La tête 11 et le talon 12 du crampon 10 sont reliés entre eux par des moyens de liaison flexibles coopérant avec un système de réglage 19 en longueur permettant d'adapter le crampon 10 à la pointure de la chaussure. Les moyens de liaison flexibles sont formés par une cordelette 20 configurée selon deux brins 20a, 20b élémentaires, espacés latéralement l'un de l'autre. Le système de réglage 19 comporte deux séries de crans 21 ménagés le long des chants intérieurs opposés de la partie ajourée du talon 12, chaque série constituant un crantage rectiligne de part et d'autre de l'axe médian longitudinal du crampon 10.The head 11 and the heel 12 of the crampon 10 are interconnected by flexible connecting means cooperating with an adjustment system 19 in length to adapt the crampon 10 to the size of the shoe. The flexible connection means are formed by a cord 20 configured according to two strands 20a, 20b elementary spaced laterally from each other. The adjustment system 19 comprises two series of notches 21 formed along the opposite inner edges of the perforated portion of the heel 12, each series constituting a rectilinear notch on either side of the longitudinal median axis of the crampon 10.

La cordelette 20 souple est réalisée de préférence en une matière textile ayant une résistance à la traction élevée et un allongement faible, par exemple à base de fibres de polyéthylène haute ténacité du type Dyneema (marque déposée par DSM). Il est clair que d'autres matières peuvent être utilisées, ayant une stabilité dimensionnelle à l'humidité, et une résistance à l'abrasion et à la coupure.The flexible cord 20 is preferably made of a textile material having a high tensile strength and a low elongation, for example based on high tenacity polyethylene fibers of the Dyneema type (trademark registered by DSM). It is clear that other materials can be used, having dimensional stability to moisture, and resistance to abrasion and cutting.

Les deux brins 20a, 20b des figures 1 et 2 sont issus d'une seule cordelette 20 formant un anneau après montage entre la tête 11 et le talon 12. A l'avant, les deux brins 20a, 20b traversent deux orifices 22, 23 de la tête 11, et sont reliés transversalement entre eux par un brin de liaison 24 inférieur. A l'arrière, chaque brin 20a, 20b traverse un orifice 25, 26 du talon 12 vers le bas, puis est engagé dans un évidement prédéterminé entre deux crans 21 de la série correspondante, pour revenir par le haut en étant fixé par son extrémité à un point d'attache 27, 28 du talon 12.The two strands 20a, 20b of the figures 1 and 2 come from a single cord 20 forming a ring after mounting between the head 11 and the heel 12. At the front, the two strands 20a, 20b through two orifices 22, 23 of the head 11, and are connected transversely to each other by a lower connecting strand 24. At the rear, each strand 20a, 20b passes through a hole 25, 26 of the heel 12 downwards, then is engaged in a predetermined recess between two notches 21 of the corresponding series, to return from above by being fixed by its end. at a point of attachment 27, 28 of the heel 12.

Le réglage longitudinal de la cordelette 20 est ainsi intégré au corps métallique du talon 12. Il suffit de détendre les deux brins 20a, 20b, et de positionner la cordelette dans les crans 21 désirés en fonction de la pointure de la chaussure. La fixation définitive du crampon 10 à la semelle de la chaussure s'effectue ensuite par basculement de la talonnière 16. Les fonctions de réglage de la pointure et de fixation du crampon, sont ainsi indépendantes l'une de l'autre.The longitudinal adjustment of the cord 20 is thus integrated into the metal body of the heel 12. Just relax the two strands 20a, 20b, and position the cord in the notches 21 desired depending on the size of the shoe. Final attachment of the crampon 10 to the sole of the shoe is then effected by tilting of the heel 16. The adjustment functions of the size and fixing the crampon, are thus independent of one another.

La figure 3 montre une variante de réalisation de la figure 2, après inversion des points d'attache 27a, 28a sous la tête 11, et le brin de liaison 24a inférieur sous le talon 12. Le reste est similaire, notamment les deux séries de crans 21 du système de réglage.The figure 3 shows an alternative embodiment of the figure 2 , after inversion of the attachment points 27a, 28a under the head 11, and the lower connecting strand 24a under the heel 12. The rest is similar, including the two series of notches 21 of the adjustment system.

Sur la variante de la figure 4, les deux extrémités de la cordelette 20, au lieu d'être fixées individuellement à des points d'attache distincts sont de la tête 11 comme à la figure 3, sont connectées directement entre elles en un point commun 29.Le reste est identique à la figure 3.On the variant of the figure 4 , the two ends of the cord 20, instead of being individually fixed to separate attachment points are of the head 11 as the figure 3 , are directly connected to each other at a common point 29.The rest is identical to the figure 3 .

La variante de la figure 5 représente deux brins de cordelette 20a, 20b indépendants l'une de l'autre, au lieu d'une seule cordelette en anneau comme sur les figures 1 à 4. Chaque brin 20a, 20b est fixé directement à l'avant à deux points d'attache 27a, 28a de la tête 11, et aux deux autres points d'attache 27, 28 du talon après passage dans les crans 21 du système de réglage 19.The variant of the figure 5 represents two cord strands 20a, 20b independent of each other, instead of a single cord ring as on the Figures 1 to 4 . Each strand 20a, 20b is attached directly to the front two attachment points 27a, 28a of the head 11, and two other attachment points 27, 28 of the heel after passing through the notches 21 of the adjustment system 19.

La figure 6 montre une autre variante avec un seul brin de cordelette 20 entre la tête 11 et le talon 12, au lieu des deux 20a, 20b comme sur la figure 5.The figure 6 shows another variant with a single strand of cord 20 between the head 11 and the heel 12, instead of the two 20a, 20b as on the figure 5 .

La cordelette 20 unique s'étend le long de l'axe médian longitudinal, et peut être ajustée en longueur avec une seule série de crans 21 située dans la partie centrale du talon 12. Les extrémités de la cordelette 20 sont fixées à des points d'attache 28, 28a respectivement du talon 12 et de la tête 11.The single cord 20 extends along the longitudinal median axis, and can be adjusted in length with a single series of notches 21 located in the central portion of the heel 12. The ends of the cord 20 are fixed at points d fastener 28, 28a respectively of the heel 12 and the head 11.

Les figures 7, 7A, 7B et 7C illustrent la possibilité d'obtenir un réglage fin de la longueur des brins de la cordelette 20a, 20b. Le corps du talon 12 comporte à cet effet deux lumières 30, 31 en forme de croissants, ayant chacun deux encoches adjacentes pour le passage des extrémités des brins 20a, 20b. On peut ainsi ajuster des demi-pointures.The FIGS. 7, 7A, 7B and 7C illustrate the possibility of obtaining a fine adjustment of the length of the strands of the cord 20a, 20b. The body of the heel 12 has for this purpose two slots 30, 31 in the form of croissants, each having two adjacent notches for the passage of the ends of the strands 20a, 20b. We can thus adjust half sizes.
