Description

Domaine technique de l'inventionTechnical field of the invention

L'invention concerne un crampon à glace comportant une armature métallique composée :

  • d'une plaque d'appui horizontale équipée de pointes d'ancrage verticales,
  • d'au moins une pointe avant en forme de lame faisant saillie de la partie antérieure de l'armature,
  • et de moyens de réglage en longueur de ladite pointe avant entre une position de recul, et une position avancée.
The invention relates to an ice crampon comprising a metal frame composed of:
  • a horizontal support plate equipped with vertical anchoring points,
  • at least one blade-shaped forward tip protruding from the front part of the frame,
  • and means for adjusting the length of said front tip between a recoil position and an advanced position.

Etat de la techniqueState of the art

Pour la pratique de l'escalade de cascades de glace, il est connu de modifier le réglage des pointes avant d'une armature de crampon pour s'adapter à l'état de la glace qui peut varier rapidement en fonction des conditions climatiques et de la température extérieure. Les pointes avant comportent généralement une pluralité de trous permettant un réglage en longueur et/ou en inclinaison. Une glace dure à très basse température ne doit pas être attaquée de la même façon qu'une glace plus tendre et plus friable à une température plus élevée. L'assemblage final nécessite deux vis de fixation traversant deux trous sélectionnés pour obtenir un blocage efficace. Il est nécessaire de retirer et de remonter les deux vis de fixation pour modifier le réglage des pointes avant, ce qui impose un certain temps de manipulation et de réglage. Un tel dispositif comprenant les caractéristiques du préambule de la revendication 1 est décrit dans le document FR 2587223 .For ice climbing practice, it is known to modify the setting of the front spikes of a crampon armature to adapt to the state of the ice which can vary rapidly depending on climatic conditions and conditions. the outside temperature. The front tips generally include a plurality of holes for adjustment in length and / or inclination. Hard ice at very low temperatures should not be attacked in the same way as softer and more friable ice at higher temperatures. The final assembly requires two fastening screws through two selected holes to obtain an effective locking. It is necessary to remove and reassemble the two fixing screws to modify the setting of the front points, this which imposes a certain time of manipulation and adjustment. Such a device comprising the features of the preamble of claim 1 is described in the document FR 2587223 .

Description de modes particuliers de réalisationDescription of particular embodiments

En référence aux figures 1 à 4, l'étrier avant 10 d'un crampon à glace comporte une armature 11 métallique en acier trempé, composée d'une plaque d'appui 12 destinée à être fixée sous la semelle de la chaussure, et d'une paire de pointes avant 13. L'étrier arrière et la barrette de liaison ne sont pas représentés sur les figures, et sont connus en soi selon le document EP1348350 .With reference to Figures 1 to 4 the front caliper 10 of an ice-crampon comprises a hardened steel frame 11 composed of a support plate 12 intended to be fastened under the sole of the boot, and a pair of spikes 13 beforehand. The rear yoke and the connecting bar are not shown in the figures, and are known per se according to the document EP1348350 .

L'armature 11 est fabriquée par découpage pliage d'une bande d'acier, suivie d'une trempe thermique pour obtenir la dureté souhaitée. Les pointes avant 13 ont des structures identiques, formées par des lames en acier fixées à la partie antérieure de l'armature 11 en s'étendant dans deux plans parallèles verticaux.The frame 11 is made by cutting a steel strip, followed by a thermal tempering to obtain the desired hardness. The front spikes 13 have identical structures formed by steel blades attached to the front portion of the armature 11 extending into two vertical parallel planes.

La face horizontale de la semelle 12 est ajourée par des ouvertures 15, 16 séparées l'une de l'autre par une entretoise 17 transversale. La périphérie de l'armature 11 est pourvue en plus d'une série de pointes verticales 14 s'étendant de chaque côté vers le bas. A titre d'exemple, les deux pointes 14 verticales situées de chaque côté de l'armature 11 au niveau de la traverse 24, sont agencées selon un V renversé, l'une vers l'avant et l'autre vers l'arrière.The horizontal face of the sole 12 is perforated by openings 15, 16 separated from each other by a transverse spacer 17. The periphery of the armature 11 is further provided with a series of vertical spikes 14 extending from each side downwards. By way of example, the two vertical points 14 located on each side of the armature 11 at the crossbar 24, are arranged in an inverted V, one forward and the other rearward.

La partie antérieure de chaque pointe avant 13 comporte un pic 18 en dent de scie prolongé le long du chant inférieur par une série de dents d'ancrage 19. La partie intermédiaire de chaque pointe avant 13 est dotée de deux orifices 20, 21 circulaires décalées dans la direction longitudinale, et autorisant le passage d'une vis de fixation 22 lors d'un réglage à deux positions des pointes avant 13. Les deux côtés antérieurs de l'armature 11 sont dotés d'une paire de trous destinés à être alignés avec l'un des deux orifices 20, 21 de chaque pointe avant 13 pour le passage de la vis 22.The front part of each nose 13 has a sawtoothed peak 18 extended along the lower edge by a series of anchoring teeth 19. The intermediate portion of each nose 13 is provided with two offset circular orifices 20, 21 in the longitudinal direction, and allowing the passage of a fastening screw 22 during a two-position adjustment of the front tips 13. The two front sides of the frame 11 are provided with a pair of holes to be aligned with one of the two orifices 20, 21 of each front tip 13 for the passage of the screw 22.

La partie postérieure de chaque pointe avant 13 est équipée d'une encoche 23 semi-ouverte ayant un profil en T à fond rectiligne constituant une liaison glissière pouvant coulisser sur une traverse 24 de positionnement pour réaliser ledit réglage.The rear portion of each nose 13 is equipped with a notch 23 semi-open having a straight-bottomed T-profile constituting a slide connection slidable on a crossbar 24 for positioning to achieve said adjustment.

La profondeur de l'encoche 23 est légèrement supérieure à l'épaisseur de la traverse 24 pour autoriser le mouvement de réglage. La traverse 24 s'étend parallèlement à la vis de fixation 22 en délimitant l'ouverture 16 avec l'entretoise 17. L'arrière de l'armature 11 est muni de deux pattes 25, 26 recourbées destinées à la mise en place de la barrette de liaison (non représentée).The depth of the notch 23 is slightly greater than the thickness of the crossbar 24 to allow the adjustment movement. The crossmember 24 extends parallel to the fastening screw 22 by delimiting the opening 16 with the spacer 17. The rear of the armature 11 is provided with two tabs 25, 26 that are curved for the positioning of the link bar (not shown).

La traverse 24 de positionnement est formée par une barrette crantée sur toute la largeur en présentant des deux côtés latéraux une succession de crans 27 et d'entailles 28 de formes rectangulaires et disposés symétriquement par rapport à la direction transversale.The crossbar 24 of positioning is formed by a notched bar over the entire width having on both sides a succession of notches 27 and notches 28 of rectangular shapes and arranged symmetrically with respect to the transverse direction.

Le réglage en longueur et le blocage de chaque pointe avant 13 s'effectuent de la manière suivante en utilisant une seule vis de fixation 22:

  • Sur les figures 1, 3A et 4, chaque pointe avant 13 se trouve dans une position de recul, avec la vis de fixation 22 traversant les orifices 20 alignés avec les trous de l'armature 11. Le flanc gauche de l'encoche 23 de chaque pointe avant 13 est en butée contre la traverse 24 pour assurer le blocage dans le sens longitudinal. Le positionnement latéral des pointes avant 13 est également assuré dans cette position grâce aux crans 27 adjacents qui les maintiennent dans les entailles 28 correspondantes. Le blocage longitudinal et latéral des pointes avant 13 est ainsi assuré au moyen d'une seule vis de fixation 22. Les deux pointes avant 13 sont immobilisées dans la position de recul, en étant parallèles et séparées l'une de l'autre par un intervalle d1 maximum. L'intervalle d1 est inférieur à la distance séparant les deux pointes verticales 14 des deux côtés de l'armature 11.
The adjustment in length and the locking of each front tip 13 is carried out in the following manner using a single fixing screw 22:
  • On the figures 1 , 3A and 4 each nose 13 is in a retracted position, with the fixing screw 22 passing through the orifices 20 aligned with the holes of the armature 11. The left flank of the notch 23 of each nose 13 abuts against the crossbar 24 to ensure the locking in the longitudinal direction. The lateral positioning of the front tips 13 is also ensured in this position thanks to the adjacent notches 27 which hold them in the corresponding notches 28. The longitudinal and lateral locking of the front spikes 13 is thus ensured by means of a single fixing screw 22. The two front spikes 13 are immobilized in the recoil position, being parallel and separated from one another by a interval d1 maximum. The interval d1 is smaller than the distance separating the two vertical points 14 on both sides of the frame 11.

Pour modifier le réglage longitudinal des pointes avant 13, il suffit de dévisser et de retirer la vis de fixation 22, puis de faire coulisser les pointes avant 13 vers la position avancée.(figure 3B), dans laquelle le flanc droit de l'encoche 23 vient en butée contre l'arête opposée de la traverse 24. Les orifices 21 des pointes avant 13 sont alors alignés avec les trous de l'armature 11, autorisant le passage de la vis de fixation 22 (figure 2). Les deux pointes avant 13 sont immobilisées dans la position avancée, en restant parallèles et séparées l'une de l'autre par le même intervalle d1 transversal.To modify the longitudinal adjustment of the front tips 13, simply unscrew and remove the fixing screw 22, then slide the front ends 13 to the advanced position. figure 3B ), wherein the right flank of the notch 23 abuts against the opposite edge of the crosspiece 24. The orifices 21 of the front spikes 13 are then aligned with the holes of the armature 11, allowing the passage of the screw fixing 22 ( figure 2 ). The two front points 13 are immobilized in the advanced position, remaining parallel and separated from each other by the same interval d1 transverse.

Sur les figures 5 et 6, on peut utiliser une seule pointe avant 13 dont l'encoche 23 correspondante est placée dans une entaille 28 prédéterminée de la traverse 24. L'autre pointe avant 13 a été enlevée après avoir retiré préalablement la vis 22, et soulevé la partie postérieure pour faire sortir la traverse 24 de l'encoche 23. Le positionnement latéral de la mono-lame dépend de l'entaille 28 sélectionnée sur la traverse 24.On the figures 5 and 6 , it is possible to use a single front tip 13 whose corresponding notch 23 is placed in a predetermined notch 28 of the cross-member 24. The other front tip 13 has been removed after having previously removed the screw 22, and raised the rear part to pull the crossbar 24 out of the notch 23. The lateral positioning of the single-blade depends on the notch 28 selected on the crossbar 24.

Dans l'exemple de la figure 5, le positionnement latéral de la pointe avant 13 est dissymétrique par rapport au plan médian longitudinal, et correspond avantageusement à un crampon qui sera chaussé à la chaussure droite de l'utilisateur. Dans la direction longitudinale, la mono-lame se trouve dans la position de recul comme à la figure 1.In the example of the figure 5 , the lateral positioning of the front tip 13 is asymmetrical with respect to the longitudinal median plane, and advantageously corresponds to a crampon which will be shod in the right shoe of the user. In the longitudinal direction, the single blade is in the recoil position as in the figure 1 .

Sur la figure 6, la mono-lame se trouve dans la position avancée comme à la figure 2. Le positionnement latéral de la pointe avant 13 correspond à celui de la figure 5.On the figure 6 , the single-blade is in the advanced position as in the figure 2 . The lateral positioning of the front tip 13 corresponds to that of the figure 5 .

En référence aux figures 7 et 8, on utilise deux pointes avant 13 avec un positionnement longitudinal dissymétrique et un positionnement latéral différent.With reference to figures 7 and 8 two front points 13 are used with asymmetrical longitudinal positioning and different lateral positioning.

Sur la figure 7, la pointe avant 13 de gauche se trouve en position de recul, tandis que la pointe avant 13 de droite est en position avancée. Les deux pointes avant 13 sont logées dans les entailles 28 d'extrémités de la traverse 24, ce qui correspond à un intervalle de séparation d1, comme celui des figures 1 et 2.On the figure 7 , the left front tip 13 is in the retracted position, while the front tip 13 of the right is in the advanced position. The two front tips 13 are housed in the notches 28 of the ends of the crossbar 24, which corresponds to a separation interval d1, as that of the figures 1 and 2 .

Sur la figure 8, la pointe avant 13 de gauche se trouve en position avancée, tandis que la pointe avant 13 de droite est en position de recul. La pointe avant 13 de gauche est logée dans une entaille 28 intermédiaire de la traverse 24, ce qui correspond à un intervalle de séparation d2, inférieur à celui de d1.On the figure 8 , the left front tip 13 is in the advanced position, while the front tip 13 of the right is in the retracted position. The left front tip 13 is housed in a notch 28 intermediate the crossbar 24, which corresponds to a separation interval d2, lower than that of d1.

Sur les figures 9 et 10, les deux pointes avant 13 sont logées dans les entailles 28 les plus rapprochées de la traverse 24, en étant écartées l'une de l'autre par un intervalle d3 minimum. Sur la figure 9, les deux pointes avant 13 se trouvent simultanément en position de recul, tandis qu'elles sont en position avancée sur la figure 10.On the figures 9 and 10 , the two front points 13 are housed in the notches 28 closest to the crossbar 24, being separated from each other by an interval d3 minimum. On the figure 9 , the two front spikes 13 are simultaneously in the retracted position, while they are in the forward position on the figure 10 .

Dans toutes les positions longitudinales et latérales représentées sur les figures précédentes, la même vis de fixation 22 passe dans l'un des orifices 20 ou 21, et permet d'assurer avec la liaison glissière un blocage efficace des pointes avant 13 mono-lame ou bi-lame.In all the longitudinal and lateral positions shown in the preceding figures, the same fastening screw 22 passes through one of the orifices 20 or 21, and makes it possible to ensure with the slide connection an efficient blocking of the front tips 13 or single-blade bimetal.

En référence à la variante des figures 11 à 13B, la queue 30 postérieure de chaque pointe avant 113, est rectiligne, et est logée à coulissement dans l'une des entailles 128 ménagées transversalement dans une aile 31 repliée vers le bas de la traverse 124. La forme des entailles 128 permet d'assurer le positionnement latéral et longitudinal des pointes avant 113.With reference to the variant of Figures 11 to 13B the rear tail of each nose 113 is rectilinear, and is slidably received in one of the notches 128 formed transversely in a downwardly folded wing 31 of the cross member 124. The shape of the notches 128 makes it possible to ensure that the lateral and longitudinal positioning of the tips before 113.

Sur l'autre variante des figures 14 à 16B, la traverse 224 de positionnement latéral comporte une série de griffes 32 recourbées vers le bas. Une encoche 223 débouche à l'extrémité de chaque pointe avant 213, et enfourche la traverse 224 dans l'intervalle entre deux griffes 32.On the other variant of Figures 14 to 16B , the lateral positioning cross member 224 comprises a series of claws 32 curved downwards. A notch 223 opens at the end of each nose before 213, and straddles the crossbar 224 in the gap between two claws 32.

    - at least one front spike (13) in the form of a blade salient from the front part of the armature (11),
    - and means for adjusting the length of said front spike (13) between a withdrawn position and an advanced position, the adjustment means comprising two apertures (20,21) arranged in the intermediate part of said front spike (13,113,213) for passage of a fixing screw (22) in both the withdrawn and advanced positions,
    characterized in that a sliding link cooperates with a positioning cross-member (24,124,224) securedly attached to the armature (11), the sliding travel corresponding to the longitudinal distance between the two apertures (20,21).
  2. The ice crampon according to claim 1, characterized in that the sliding link is formed by a semi-open groove (23,223) arranged in the rear part of the front spike (13,213) and designed to slide on the positioning cross-member (24,224).
  3. The ice crampon according to claim 1, characterized in that the positioning cross-member (24) is notched over its whole width with a succession of rectangular notches (27) and indentations (28) arranged symmetrically on the two opposite sides.
  4. The ice crampon according to claim 2, characterized in that the rear groove of the front spike (13) presents a T-shaped profile with a straight bottom extending in a direction parallel to the longitudinal offset of the two apertures (20,21).
  5. The ice crampon according to claim 3, characterized in that the front spike (13,113) is arranged in a predefined indentation (28,128) of the cross-member (24,124) and is securedly blocked in the transverse direction by the adjacent notches (27) in both the withdrawn and advanced positions.
  6. The ice crampon according to claim 2, characterized in that the depth of the groove (23,223) is slightly larger than the thickness of the cross-member (24,224) to enable longitudinal adjustment.
  7. The ice crampon according to one of the foregoing claims, characterized in that the positioning cross-member (24,124,224) extends in a direction parallel to the fixing screw (22) enabling one or two front spikes (13,113,213) to be fitted with a predefined longitudinal and transversal positioning.
  8. The ice crampon according to claim 1, characterized in that each front spike (113) has a straight rear tail (30) which is housed sliding in one of the indentations (128) arranged transversely in a wing (31) folded down towards the bottom of the cross-member (124).
  9. The ice crampon according to claim 1, characterized in that the lateral positioning cross-member (224) comprises a series of downwardly-curved claws (32), and that the tail of each front spike (213) straddles the cross-member (224) in the gap between two adjacent claws (32).
