Description d'un mode de réalisation préférentiel.Description of a preferred embodiment.

En référence à la figure 1, un crampon 10 d'alpinisme comporte une armature 12 métallique dotée d'une pluralité de dents 14 d'ancrage verticales destinées à pénétrer dans la glace ou la neige dure pour permettre la progression en terrain glaciaire en toute sécurité. L'armature 12 est montée sous la semelle 16 d'une chaussure 17 de montagne, et est composée d'un cadre antérieur 12A relié à un cadre postérieur 12B par une barrette de liaison 18, laquelle est réglable en longueur en fonction de la pointure de la chaussure.Referring to Figure 1, a mountaineering crampon 10 has a frame 12 metal with a plurality of vertical anchoring teeth 14 intended to penetrate ice or hard snow to allow progression in terrain safely. The frame 12 is mounted under the sole 16 of a mountain shoe 17, and is composed of a front frame 12A connected to a rear frame 12B by a connecting bar 18, which is adjustable in length depending on the shoe size.

Le cadre antérieur 12A de l'armature 12 est pourvu d'un premier élément de fixation 20 en forme d'étrier prenant appui sur le rebord avant 22 de la semelle 16. L'étrier 20 est conformé en U au moyen d'un fil d'acier, dont les extrémités opposées sont montées à basculement autour d'un axe transversal 24. L'étrier 20 peut aussi être remplacé par une butée équipée de sangles recouvrant l'avant de la chaussure. The front frame 12A of the frame 12 is provided with a first element of fixing 20 in the form of a stirrup bearing on the front edge 22 of the sole 16. The stirrup 20 is U-shaped by means of a steel wire, the ends of which opposite are pivotally mounted around a transverse axis 24. The bracket 20 can also be replaced by a stop fitted with straps covering the front of the shoe.

Le cadre postérieur 12B de l'armature 12 est équipé d'un deuxième élément de fixation 26 venant en engagement avec le rebord postérieur 28 du talon de la semelle 16. Le deuxième élément de fixation 26 comprend à titre d'exemple un étrier métallique.The rear frame 12B of the frame 12 is equipped with a second element of attachment 26 coming into engagement with the rear edge 28 of the heel of the sole 16. The second fastening element 26 comprises, for example, a metal bracket.

Un dispositif d'attache 30 à levier de manoeuvre 32 latéral est associé au deuxième étrier de fixation 26 pour assurer le blocage et le déblocage du talon de la chaussure 17 sur le crampon 10, suite à un déplacement longitudinal du deuxième étrier de fixation 26 par rapport au premier étrier 20 du cadre antérieur 12A. Une sangle de sécurité 34 est solidarisée au deuxième étrier de fixation 26, de manière à entourer la tige de la chaussure 17 au moyen d'un système de retenue 36.A fastening device 30 with lateral operating lever 32 is associated with the second fixing bracket 26 for blocking and unblocking the heel of the shoe 17 on the stud 10, following a longitudinal displacement of the second fixing bracket 26 relative to the first bracket 20 of the front frame 12A. A safety strap 34 is secured to the second fixing bracket 26, so to surround the upper of the shoe 17 by means of a retaining system 36.

En référence aux figures 2 à 5, le cadre postérieur 12B de l'armature 12 comporte une surface d'appui 38 de la semelle 16, ladite surface étant ajourée dans la partie centrale par une ouverture 40. Une extension 42 repliée de la branche 43 transversale du cadre postérieur 12B est pourvue d'un orifice 44 rectangulaire pour le passage de la barrette de liaison 18.Referring to Figures 2 to 5, the rear frame 12B of the frame 12 comprises a bearing surface 38 of the sole 16, said surface being perforated in the part central through an opening 40. An extension 42 folded back from the branch 43 transverse of the rear frame 12B is provided with a rectangular orifice 44 for the passage of the connecting bar 18.

De chaque côté du corps du cadre postérieur 12B est agencée une crémaillère 46 ayant plusieurs crans échelonnés dans la direction longitudinale pour l'ajustage du dispositif d'attache 30.On each side of the body of the rear frame 12B is arranged a rack 46 having several notches staggered in the longitudinal direction for adjusting the fastening device 30.

L'une des extrémités 48 du deuxième étrier de fixation 26 est montée directement dans la crémaillère 46 du côté opposé au levier de manoeuvre 32. L'autre extrémité 50 de l'étrier de fixation 26 traverse une douille 52 montée à rotation libre sur un prolongement 54 coudé du levier de manoeuvre 32. L'axe d'articulation 56 du levier de manoeuvre 32 est introduit dans la crémaillère 46 correspondante, et est décalé par rapport à la douille 52 rotative portée par le prolongement 54. Chaque extrémité 48, 50 de l'étrier de fixation 26 comprend un méplat 58 (visible sur l'extrémité 48 à la figure 5) ayant une largeur supérieure au diamètre des trous de réglage ménagés dans les crémaillères 46.One of the ends 48 of the second fixing bracket 26 is mounted directly in the rack 46 on the side opposite to the operating lever 32. The other end 50 of the fixing bracket 26 passes through a socket 52 mounted for free rotation on a bent extension 54 of the operating lever 32. The articulation axis 56 the operating lever 32 is introduced into the corresponding rack 46, and is offset with respect to the rotary sleeve 52 carried by the extension 54. Each end 48, 50 of the fixing bracket 26 comprises a flat 58 (visible on the end 48 in FIG. 5) having a width greater than the diameter of the holes adjustment housings in the racks 46.

L'étrier de fixation 26 comporte en plus deux boucles 60 servant à l'accrochage de la sangle de sécurité 34. The fixing bracket 26 additionally comprises two loops 60 serving for the attachment of the safety strap 34.

Le levier de manoeuvre 32 de forme coudée constitue une genouillère avec le brin latéral du deuxième étrier de fixation 26.The angled operating lever 32 constitutes a toggle with the strand side of the second fixing bracket 26.

Dans l'état de déblocage du dispositif d'attache 30 (figures 3 et 4), la genouillère se trouve en position brisée, et le levier de manoeuvre 32 est basculé vers l'avant en restant articulé au niveau de la crémaillère 46 par l'axe 56, lequel se trouve au-dessus du brin latéral de l'étrier de fixation 26.In the unlocked state of the fastening device 30 (Figures 3 and 4), the toggle is is in the broken position, and the operating lever 32 is tilted forward in remaining articulated at the rack 46 by the axis 56, which is located above of the lateral strand of the fixing bracket 26.

La commande vers l'état de blocage du dispositif d'attache 30 (figures 1 et 2) s'effectue en faisant pivoter le levier de manoeuvre 32 latéral dans le sens des aiguilles d'une montre indiqué sur la figure 4 par la flèche F1. La douille 52 est entraínée dans le même sens en décrivant un arc de cercle centré sur l'axe 56. Le deuxième étrier de fixation 26 est tiré en translation vers l'avant (flèche F2), de manière à serrer au maximum le rebord postérieur 28 du talon de la semelle 16. Durant ce déplacement se produit le passage de point mort de la genouillère lorsque l'axe 56 passe en-dessous du brin latéral de l'étrier de fixation 26.The control towards the blocking state of the fastening device 30 (FIGS. 1 and 2) is carried out by pivoting the lateral operating lever 32 in the direction of clockwise indicated in figure 4 by arrow F1. The socket 52 is driven in the same direction by describing an arc centered on the axis 56. The second fixing bracket 26 is pulled in translation forward (arrow F2), so as to tighten as much as possible the rear edge 28 of the heel of the sole 16. During this movement, the neutral knee switch passes when the axis 56 passes below the lateral strand of the fixing bracket 26.

La présence de la genouillère rend cette position de blocage du levier de manoeuvre 32 parfaitement stable. L'extrémité de préhension du levier de manoeuvre 32 s'insère en plus dans l'une des boucles 60 de l'étrier 26 de manière à éviter tout déblocage involontaire.The presence of the toggle joint makes this locking position of the lever maneuver 32 perfectly stable. The gripping end of the lever operation 32 also fits into one of the loops 60 of the stirrup 26 so to avoid any unintentional unlocking.

La commande vers l'état de déblocage du dispositif d'attache 30 est opérée en tirant sur l'anneau 62 du levier de manoeuvre 32 dans le sens de la flèche F3 (figure 2). Le processus est inversé par rapport à celui du blocage, et le levier de manoeuvre 32 revient dans la position de la figure 3 en provoquant la translation du deuxième étrier de fixation 26 vers l'arrière (flèche F4). Il en résulte un dégagement suffisant pour obtenir la libération du talon 28 de la chaussure.The command to the unlocking state of the fastening device 30 is operated in pulling on the ring 62 of the operating lever 32 in the direction of the arrow F3 (figure 2). The process is reversed from that of blocking, and the lever maneuver 32 returns to the position of FIG. 3 causing the translation of the second fixing bracket 26 towards the rear (arrow F4). This results in a clearance sufficient to obtain the release of the heel 28 of the shoe.

En référence aux figures 6 et 7, la disposition symétrique des deux crémaillères 46 dans le corps du cadre postérieur 12B, permet la translation de l'ensemble étrier de fixation 26 et dispositif d'attache 30 entre plusieurs positions. Cet ajustage s'effectue sans démontage, en faisant basculer le levier 32 et l'étrier 26 complètement vers l'avant. La mise en correspondance du méplat 58 avec la fente longitudinale des crémaillères 46 autorise la translation jusqu'à une position de réglage prédéterminée. Cette position longitudinale reste stable après rappel de l'étrier 26 vers l'arrière.Referring to Figures 6 and 7, the symmetrical arrangement of the two racks 46 in the body of the rear frame 12B, allows the translation of the caliper assembly from attachment 26 and attachment device 30 between several positions. This adjustment is carried out without disassembly, by tilting the lever 32 and the stirrup 26 completely forward. The matching of flat 58 with the slot longitudinal of the racks 46 allows the translation to a position of predetermined setting. This longitudinal position remains stable after recalling the stirrup 26 towards the rear.

Les deux crémaillères 46 symétriques peuvent être remplacées par tout autre moyen d'ajustage pour régler le positionnement longitudinal du deuxième étrier de fixation 26 par rapport au cadre postérieur 12B.The two symmetrical racks 46 can be replaced by any other adjustment means for adjusting the longitudinal positioning of the second stirrup attachment 26 relative to the rear frame 12B.

Il est clair que le dispositif d'attache 30 à genouillère précédemment décrit peut être utilisé sans système de réglage à crémaillère du dispositif d'attache 30. Il reste alors le réglage en longueur de la barrette de liaison 18 en fonction de la pointure de la chaussure.It is clear that the toggle fastener 30 described above can be used without rack and pinion adjustment system of the fastening device 30. It then remains the length adjustment of the connecting bar 18 as a function of the size of the shoe.

Sur la variante des figures 8 et 9, le mécanisme d'attache 30 à genouillère est constitué par une biellette 70 intermédiaire sur laquelle sont articulés l'étrier de fixation 26 et le levier de manoeuvre 32. La biellette 70 est montée à pivotement sur un axe 72 d'une patte solidaire du cadre 12B.In the variant of FIGS. 8 and 9, the attachment mechanism 30 to the toggle joint is constituted by an intermediate link 70 on which are articulated the stirrup fixing 26 and the operating lever 32. The rod 70 is pivotally mounted on an axis 72 of a lug secured to the frame 12B.

Au lieu de monter le dispositif d'attache 30 à genouillère sur la cadre postérieur 12B, il est également possible de l'inverser en l'adaptant sur le cadre antérieur 12A.Instead of mounting the toggle fastener 30 on the rear frame 12B, it is also possible to reverse it by adapting it to the front frame 12A.

Selon une autre variante, un deuxième levier de manoeuvre (non représenté) peut être monté symétriquement sur l'armature de manière à constituer un mécanisme à double leviers latéraux.According to another variant, a second operating lever (not shown) can be mounted symmetrically on the frame so as to constitute a mechanism double side levers.
