Description

Domaine technique de l'inventionTechnical field of the invention

L'invention est relative à un manche de préhension d'un piolet à glace, comprenant :

  • une poignée en matière plastique équipée d'une butée d'appui de la main, et à l'opposé d'une cale intermédiaire,
  • et des moyens de réglage de la cale intermédiaire le long du manche.
The invention relates to a handle for gripping an ice ax, comprising:
  • a plastic handle equipped with a support stop of the hand, and opposite an intermediate wedge,
  • and means for adjusting the intermediate shim along the handle.

État de la techniqueState of the art

La tenue du manche d'un piolet dans la main d'un alpiniste constitue un facteur essentiel d'efficacité pour la pénétration de la pique dans la glace. L'alpiniste tient généralement le bout inférieur du manche pour disposer du couple de frappe le plus important approprié à une force de pénétration optimum de la pique dans la glace. Un tel piolet est généralement utilisé en piolet-traction sans dragonne, lors d'escalades extrêmes, la cascade de glace et la compétition. Il a déjà été proposé des poignées de piolets permettant d'adapter la position de la butée d'appui inférieure à la morphologie de la main de l'utilisateur.Holding the handle of an ice ax in the hand of a mountaineer is an essential factor of effectiveness for the penetration of the spades into the ice. The mountaineer usually holds the bottom end of the shaft to provide the largest strike torque appropriate for optimum penetration force of the pike into the ice. Such an ice ax is generally used in ice ax without traction, during extreme climbing, ice climbing and competition. It has already been proposed ice axes handles for adapting the position of the lower abutment to the morphology of the hand of the user.

Le document EP1533006 décrit une butée d'appui inférieur avec un embout de réglage monté à pivotement sur la poignée de préhension. La cale intermédiaire qui se trouve à l'opposé, est formée par une protubérance fixe non réglable.The document EP1533006 discloses a lower bearing abutment with a setting tip pivotally mounted on the handle. The intermediate wedge which is opposite, is formed by a non-adjustable fixed protuberance.

Le document US 2006/0070248 prévoit un embout de réglage télescopique par adjonction d'un certain nombre d'entretoises modifiant la longueur de prise en main.The document US 2006/0070248 provides a telescopic adjusting end by adding a number of spacers changing the grip length.

A l'opposé de cette butée inférieure, il est également connu de régler la cale intermédiaire le long du manche entre une position abaissée et une position relevée. Il suffit de desserrer la cale pour obtenir un certain jeu radial, puis de la faire coulisser dans une position donnée le long du manche, et de la bloquer dans cette position. Un réglage sur le site par un ensemble vis et écrou de fixation est long, nécessite l'emploi d'outils, et ne permet pas d'obtenir un verrouillage positif de la cale intermédiaire si le serrage de l'écrou est insuffisant.In contrast to this lower stop, it is also known to adjust the intermediate shim along the handle between a lowered position and a raised position. Simply loosen the wedge to obtain a certain radial clearance, then slide it in a given position along the handle, and block it in this position. An adjustment on the site by a screw and nut assembly is long, requires the use of tools, and does not allow to obtain a positive locking of the intermediate shim if the tightening of the nut is insufficient.

Dans le document FR 2918898 , on utilise un levier à came pour le réglage de la cale intermédiaire du piolet, le levier étant diamétralement opposé par rapport à la cale intermédiaire. Le manche est dépourvu de poignée plastique, et ne possède pas de butée d'appui inférieur.In the document FR 2918898 a cam lever is used to adjust the intermediate shim of the ice ax, the lever being diametrically opposite to the intermediate shim. The handle has no plastic handle and does not have a lower bearing stop.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à réaliser un manche de piolet ayant une poignée de préhension à tenue améliorée, et facilement réglable sans outil.The object of the invention is to achieve an ice ax handle having a grip grip improved, and easily adjustable without tools.

Le manche du piolet selon l'invention est caractérisé en ce que la cale intermédiaire est pourvue d'un levier auxiliaire pivotant comportant :

  • une partie incurvée constituant une cale d'index,
  • et une came servant au blocage et au déblocage de l'ensemble cale intermédiaire et cale d'index dans une position prédéterminée le long du manche.
The handle of the ice ax according to the invention is characterized in that the intermediate shim is provided with a pivoting auxiliary lever comprising:
  • a curved portion constituting an index wedge,
  • and a cam for locking and unlocking the intermediate shim and shim assembly in a predetermined position along the shaft.

Le réglage de la double cale intermédiaire est très rapide, peut être effectué par l'alpiniste à tout moment sur le site, et sans nécessiter d'outils. Il suffit d'actionner le levier auxiliaire vers la position déverrouillée, de faire coulisser la double cale intermédiaire vers la position souhaitée, et de rebloquer le levier vers la position verrouillée.The adjustment of the double intermediate wedge is very fast, can be done by the mountaineer at any time on the site, and without the need for tools. Simply push the auxiliary lever to the unlocked position, slide the double intermediate wedge to the desired position, and re-lock the lever to the locked position.

La première cale intermédiaire sert de cale de changement de main à la partie supérieure, et coopère directement à la partie inférieure avec la deuxième cale d'index du levier auxiliaire de blocage et de déblocage.The first intermediate wedge serves as a hand-shift wedge at the upper part, and cooperates directly with the lower part with the second index wedge of the auxiliary locking and unlocking lever.

Selon un mode de réalisation préférentiel, le levier auxiliaire est intercalé entre deux doigts adjacents de la cale intermédiaire en étant monté à pivotement sur un axe servant de moyen d'assemblage desdits doigts.According to a preferred embodiment, the auxiliary lever is interposed between two adjacent fingers of the intermediate shim being pivotally mounted on an axis serving as means for assembling said fingers.

Selon un mode réalisation préférentiel, le manche du piolet est équipé d'une série de crans de réglage, échelonnés à intervalles réguliers dans le sens de la hauteur pour former une crémaillère qui détermine une première zone de positionnement en prise avec les crans. Au-dessus de la première zone de positionnement, le manche possède une partie lisse formant une deuxième zone de positionnement hors des crans de la poignée.According to a preferred embodiment, the handle of the ice ax is equipped with a series of adjustment notches, staggered at regular intervals in the direction of the height to form a rack which determines a first positioning zone in engagement with the notches. Above the first positioning zone, the handle has a smooth portion forming a second positioning zone outside the notches of the handle.

Description détaillée de l'inventionDetailed description of the invention

En référence aux figures 1 à 6, un manche 10 de préhension d'un piolet à glace, comporte une poignée 13 équipée d'une butée 11 d'appui inférieur de la main, et d'une cale intermédiaire 12 servant à un changement de main. Un tel piolet est généralement utilisé en piolet-traction sans dragonne, lors d'escalades extrêmes, la cascade de glace et la compétition.With reference to Figures 1 to 6 , a handle 10 for gripping an ice ax, comprises a handle 13 equipped with a stop 11 for lower support of the hand, and an intermediate shim 12 for a change of hand. Such an ice ax is generally used in ice ax without traction, during extreme climbing, ice climbing and competition.

Le manche 10 est réalisé de préférence, en alliage d'aluminium, et la poignée 13 à la base du manche 10, est en matière plastique. Elle est délimitée par la butée 11 d'appui inférieur et la cale intermédiaire 12 pour protéger en grande partie la main gantée de l'utilisateur des chocs contre la glace. La poignée 13 peut être surmoulée sur l'extrémité du manche 10 ou y être rapportée par tout autre procédé d'assemblage.The handle 10 is preferably made of aluminum alloy, and the handle 13 at the base of the handle 10 is made of plastic. It is delimited by the abutment stop 11 and the intermediate shim 12 to largely protect the gloved hand of the user from shocks against the ice cream. The handle 13 may be overmolded on the end of the handle 10 or be reported by any other method of assembly.

La butée 11 d'appui est avantageusement réglable en inclinaison à l'extrémité inférieure de la poignée 13. Le réglage en inclinaison de la butée 11 peut être opéré par tout autre moyen de blocage, comme décrit dans le document EP1533006 de la demanderesse.The bearing abutment 11 is advantageously adjustable in inclination at the lower end of the handle 13. The tilt adjustment of the abutment 11 can be operated by any other locking means, as described in the document EP1533006 of the plaintiff.

Entre la butée 11 et la cale intermédiaire 12, la poignée 13 présente une partie galbée 16 ergonomique correspondant à la zone de prise en main. Elle est pourvue d'une pluralité de nervures 17 pour améliorer la tenue et l'adhérence de la main.Between the abutment 11 and the intermediate shim 12, the handle 13 has a curved ergonomic portion 16 corresponding to the grip zone. It is provided with a plurality of ribs 17 to improve the grip and grip of the hand.

La cale intermédiaire 12 est en forme de pince ouvrable comportant un corps 18 prolongé par deux doigts 19a, 19b adjacents. Le corps 18 est en matière plastique déformable par élasticité pour permettre sa mise en place le long d'une portion intermédiaire 10a du manche 10. Cette portion intermédiaire 10a se trouve au-dessus de la partie galbée 16, et détermine une première zone de positionnement ZP1 de la cale intermédiaire 12. Les deux doigts 19a, 19b sont rapprochés l'un vers l'autre pour former une seule surface d'appui en saillie par rapport au manche 10, et légèrement incurvée vers le haut. Un moyen d'assemblage 21 à vis 21a et écrou 21b traverse des orifices alignés des deux doigts 19a, 19b pour les maintenir dans la position rapprochée.The intermediate shim 12 is in the form of an openable clamp comprising a body 18 extended by two fingers 19a, 19b adjacent. The body 18 is made of resiliently deformable plastic material to allow its placement along an intermediate portion 10a of the handle 10. This intermediate portion 10a is above the curved portion 16, and determines a first positioning zone ZP1 of the intermediate wedge 12. The two fingers 19a, 19b are brought closer to each other to form a single bearing surface projecting from the handle 10, and slightly curved upwards. An assembly means 21 with screw 21a and nut 21b through aligned orifices of the two fingers 19a, 19b to maintain them in the close position.

La portion intermédiaire 10a rectiligne du manche 10 est équipée d'une série de crans 22 de réglage, échelonnés à intervalles réguliers dans le sens de la hauteur pour former une crémaillère disposée au-dessus des nervures 17. Cette crémaillère détermine la première zone de positionnement ZP en prise avec les crans 22. Un levier auxiliaire 23 est monté à pivotement entre les deux doigts 19a, 19b, et est muni d'une came 23b de blocage destinée à coopérer avec l'un des crans 22 de la crémaillère en fonction du réglage souhaité le long de la première zone de positionnement ZP1. L'axe de pivotement du levier auxiliaire 23 est formé avantageusement par la vis 21a. Le levier auxiliaire 23 peut être actionné manuellement entre une position déverrouillée (figure 6), et une position verrouillée (figures 4 et 5).The rectilinear intermediate portion 10a of the handle 10 is equipped with a series of adjustment notches 22, staggered at regular intervals in the direction of the height to form a rack disposed above the ribs 17. This rack determines the first positioning zone ZP engaged with the notches 22. An auxiliary lever 23 is pivotally mounted between the two fingers 19a, 19b, and is provided with a locking cam 23b intended to cooperate with one of the notches 22 of the rack according to the setting desired along the first ZP1 positioning zone. The pivot axis of the auxiliary lever 23 is advantageously formed by the screw 21a. The auxiliary lever 23 can be actuated manually between an unlocked position ( figure 6 ), and a locked position ( Figures 4 and 5 ).

Le levier auxiliaire 23 présente avantageusement une partie incurvée 23a relevée vers le haut pour constituer une cale d'index dans la position verrouillée.The auxiliary lever 23 advantageously has a curved portion 23a raised upwards to form an index wedge in the locked position.

L'ensemble des pièces formées par la cale intermédiaire 12 et le levier auxiliaire 23 assure ainsi une double fonction servant à la fois de cale de changement de main et de cale d'index. Cette dernière est placée sous la cale intermédiaire, et du même côté.The set of parts formed by the intermediate wedge 12 and the auxiliary lever 23 thus provides a dual function for both change hands and index wedge. The latter is placed under the intermediate hold, and on the same side.

Dans la position déverrouillée illustrée à la figure 6, le levier auxiliaire 23 est relevé pour débloquer la came 23b des crans 22 de la crémaillère. L'ensemble cale intermédiaire 12 et cale d'index forme une double cale pouvant coulisser (voir flèche F) simultanément le long de la première zone de positionnement ZP1 du manche 10a pour assurer le réglage.In the unlocked position illustrated in figure 6 , the auxiliary lever 23 is raised to unlock the cam 23b notches 22 of the rack. The intermediate wedge assembly 12 and index wedge forms a double slidable wedge (see arrow F) simultaneously along the first ZP1 positioning zone of the handle 10a to ensure adjustment.

Il suffit ensuite de faire pivoter le levier auxiliaire 23 vers la position verrouillée pour immobiliser la cale intermédiaire 12 et la cale d'index dans la position de réglage choisie, suite à l'engagement de la came 23b du levier auxiliaire 23 dans l'un des crans 22 de la crémaillère.Then simply rotate the auxiliary lever 23 to the locked position to immobilize the intermediate shim 12 and the index wedge in the selected adjustment position, following the engagement of the cam 23b of the auxiliary lever 23 in one notches 22 of the rack.

La figure 4 montre le levier 23 de la cale d'index verrouillé dans un cran 22 inférieur de la première zone de positionnement ZP1 du manche 10a.The figure 4 shows the lever 23 of the index wedge locked in a notch 22 of the first lower ZP1 positioning zone of the handle 10a.

Sur la figure 5, le levier 23 de la cale d'index se trouve verrouillé dans un cran 22 supérieur de la première zone de positionnement ZP1 du manche 10a.On the figure 5 , the lever 23 of the index wedge is locked in a notch 22 upper of the first positioning zone ZP1 of the handle 10a.

Sur la figure 7, la cale intermédiaire 12 et le levier 23 de la cale d'index sont réglables sur une partie lisse du manche 10. Ce réglage est possible le long d'une deuxième zone de positionnement ZP2 hors des crans 22. Le blocage intervient par coincement direct de la came 23b sur le manche 10 métallique lorsque le levier auxiliaire 23 est abaissé vers la position verrouillée.On the figure 7 , the intermediate shim 12 and the lever 23 of the index wedge are adjustable on a smooth portion of the handle 10. This adjustment is possible along a second ZP2 positioning zone out of the notches 22. The locking occurs by direct jamming of the cam 23b on the metal handle 10 when the auxiliary lever 23 is lowered to the locked position.
