Description

L'invention se rapporte à un pied de piquet des neiges, destiné à être planté dans un manteau neigeux préalablement foré et à soutenir un piquet via une articulation flexible.The invention relates to a snow picket foot intended to be planted in a previously drilled snowpack and to support a stake via a flexible hinge.

L'invention se rapporte plus particulièrement à un pied de piquet des neiges comprenant un corps s'étendant suivant une direction axiale, des moyens de retenue pour s'opposer à un effort de traction suivant la direction axiale, montés en enfilade autour du corps entre des bagues également montées en enfilade et un moyen de serrage des moyens de retenue et des bagues le long du corps.The invention relates more particularly to a snow picket foot comprising a body extending in an axial direction, retaining means for opposing a tensile force in the axial direction, mounted in a row around the body between rings also mounted in a row and a means for clamping the retaining means and rings along the body.

Le montage des moyens de retenue et des bagues en enfilade autour du corps permet de remplacer un moyen de retenue ou une bague défectueuse, par une action simple sur le moyen de serrage.The mounting retaining means and rings in a row around the body allows to replace a retaining means or a defective ring, by a simple action on the clamping means.

Un pied de piquet des neiges de ce type est connu notamment du document DE 85 184 38 . Selon ce document, les bagues, rigides, sont intercalées entre les moyens de retenue, flexibles, qui ont une forme régulière, par exemple en disque, en triangle ou en quadrilatère et peuvent tourner les uns par rapport aux autres autour de la direction axiale, plus ou moins facilement en fonction de l'effort de serrage.A snow picket foot of this type is known in particular from the document DE 85 184 38 . According to this document, the rigid rings are interposed between the flexible retaining means, which have a regular shape, for example disk, triangle or quadrilateral and can rotate relative to each other around the axial direction, more or less easily depending on the clamping force.

Les documents US 5 291 703 et US 5 568 785 divulguent un pied de piquet destiné à être planté dans le sol. Des moyens de retenue ont une forme filaire et sont bloqués en rotation par rapport au corps du pied de piquet, par un montage de chaque moyen de retenue d'une façon indépendante des autres.The documents US 5,291,703 and US 5,568,785 disclose a stake foot intended to be planted in the ground. Retaining means have a wire shape and are locked in rotation relative to the body of the stake foot, by mounting each retaining means independently of the others.

Le document WO 2009/014597 divulgue un pied de piquet des neiges dont les moyens de retenue comprennent des poils ou des faisceaux de poils insérés dans des perçages le long du corps du pied de piquet.The document WO 2009/014597 discloses a snow picket foot whose retaining means comprise bristles or bundles of bristles inserted in bores along the body of the stake foot.

Le but de l'invention est ainsi de modifier un pied de piquet des neiges à moyens de retenue et à bagues montés en enfilade, pour en améliorer le maintien et l'emprise dans le manteau neigeux.The object of the invention is thus to modify a snow picket foot retaining means and rings mounted in a row, to improve the maintenance and grip in the snowpack.

A cet effet, l'invention a pour objet un pied de piquet des neiges comprenant un corps s'étendant suivant une direction axiale, des moyens de retenue pour s'opposer à un effort de traction suivant la direction axiale, montés en enfilade autour du corps entre des bagues également montées en enfilade et un moyen de serrage des moyens de retenue et des bagues le long du corps, caractérisé en ce que les moyens de retenue comprennent une base dans laquelle est ménagée une ouverture pour le montage par enfilade et une ou plusieurs branches raccordées à la base et les bagues comprennent une ouverture pour le montage en enfilade, qui débouche dans un logement formé dans les bagues et dans lequel est reçue la base des moyens de retenue, des encoches qui s'ouvrent dans le logement en permettant aux branches des moyens de retenue de s'étendre par rapport aux bagues et des moyens de blocage en rotation des bagues les unes par rapport aux autres, distants dans une même bague d'une hauteur suivant la direction axiale pour contrôler la compression de la base des moyens de retenue, exercée par le moyen de serrage, entre une bague et la suivante le long de l'enfilade.For this purpose, the subject of the invention is a snow picket foot comprising a body extending in an axial direction, retaining means for opposing a tensile force in the axial direction, mounted in a row around the body between rings also mounted in a row and a means for clamping the retaining means and rings along the body, characterized in that the retaining means comprise a base in which is formed an opening for the assembly thread and one or a plurality of branches connected to the base and the rings comprise an opening for mounting in a row, which opens into a housing formed in the rings and in which is received the base of the retaining means, notches which open into the housing allowing the branches of the retaining means to extend relative to the rings and means for locking in rotation of the rings relative to each other, distant in the same ring of a h author in the axial direction to control the compression of the base of the retaining means, exerted by the clamping means, between a ring and the next along the thread.

Par cet agencement, on fixe la configuration des branches des moyens de retenue les unes par rapport aux autres le long du corps du pied de piquet, tout en rigidifiant l'enfilade des bagues et en contrôlant la compression des moyens de retenue. D'où il résulte que le pied de piquet des neiges selon l'invention présente un maintien et une emprise dans le manteau neigeux améliorés.By this arrangement, the configuration of the branches of the retaining means relative to each other is fixed along the body of the stake foot, while stiffening the enfilade of the rings and controlling the compression of the retaining means. From which it follows that the snow picket foot according to the invention has a maintenance and a grip in the snowpack improved.

Il est prévu de pourvoir les bagues de surfaces inclinées ou bombées qui déforment la base des moyens de retenue reçue dans le ledit logement et donnent une inclinaison aux branches par rapport à la direction axiale. Il est également prévu de ramifier les branches et de les pourvoir de reliefs. Ces agencements concourent à augmenter l'emprise du pied de piquet dans le manteau neigeux.It is intended to provide the inclined or curved surface rings which deform the base of the retaining means received in said housing and give an inclination to the branches relative to the axial direction. It is also planned to branch branches and provide them with reliefs. These arrangements combine to increase the grip of the stake foot in the snowpack.

Selon un mode avantageux d'exécution de l'invention, les moyens de blocage d'une bague présentent un angle de décalage par rapport aux moyens de blocage de la même bague vis-à-vis desquels ils sont distants de ladite hauteur suivant la direction axiale. Cet agencement permet d'enfiler les bagues suivant un pas angulaire égal à l'angle de décalage et de multiplier, le long du corps du pied de piquet, les orientations angulaires perpendiculairement à la direction axiale, des branches des moyens de retenue étendues en travers des encoches. D'où là encore une amélioration de l'emprise du pied de piquet des neiges.According to an advantageous embodiment of the invention, the locking means of a ring have an offset angle with respect to the locking means of the same ring vis-à-vis which they are distant from said height in the direction axial. This arrangement makes it possible to thread the rings in an angular pitch equal to the offset angle and to multiply, along the body of the stake foot, the angular orientations perpendicular to the axial direction, the branches of the retaining means extended across. notches. Hence again an improvement in the grip of the snow picket foot.

Figures 1 et 2, un pied de piquet des neiges comprend un corps 1 s'étendant suivant une direction axiale L. Le corps est formé d'une pièce de liaison 3 avec l'articulation d'un piquet, non représentée, et d'une pièce 5, par exemple une tige, autour de laquelle des moyens de retenue 7 et des bagues 9 sont montés en enfilade. Un moyen de serrage 11, ici une vis coopérant avec une extrémité filetée 13 de la tige, assure le maintien des moyens de retenue 7 entre les bagues 9. La construction du corps du pied de piquet en deux parties répond au besoin d'un pied tout démontable. Cependant, le corps peut être aussi en une seule pièce. Comme indiqué en introduction, le montage des moyens de retenue 7 et des bagues 9 en enfilade autour de la tige 5 permet de remplacer un moyen de retenue ou une bague défectueuse, par une action simple sur le moyen de serrage 11. Figures 1 and 2 , a snow picket foot comprises a body 1 extending in an axial direction L. The body is formed of a connecting piece 3 with the articulation of a peg, not shown, and a part 5, for example a stem, around which retaining means 7 and rings 9 are mounted in a row. A clamping means 11, here a screw cooperating with a threaded end 13 of the rod, ensures the holding of the retaining means 7 between the rings 9. The construction of the body of the two-piece stake foot meets the need for a foot all removable. However, the body can also be in one piece. As indicated in the introduction, the mounting of the retaining means 7 and the rings 9 in a row around the rod 5 makes it possible to replace a retaining means or a defective ring by a simple action on the clamping means 11.

Les moyens de retenue 7 comprennent une base 15 dans laquelle une ouverture 17 est ménagée pour le montage en enfilade et une ou plusieurs branches 19 raccordées à leur base 15. Le moyen de retenue peut comprendre, figure 3, des branches 21 ramifiées en Y, ou figures 4 et 6, des branches multi-ramifiées 23. La ramification permet aux branches de pointer avantageusement dans différentes directions autour du corps du pied de piquet. Cet agencement augmente l'emprise des moyens de retenue dans la neige. De surcroît, lors de l'insertion du pied de piquet, le frottement des branches ramifiées contre la paroi du conduit foré dans le manteau neigeux est plus homogène. On évite ainsi de sculpter dans le conduit des rainures continues qui diminuent l'emprise des branches et leur résistance à la traction.The retaining means 7 comprise a base 15 in which an opening 17 is provided for the row assembly and one or more branches 19 connected to their base 15. The retaining means may comprise, figure 3 branch branches 21 branched in Y, or Figures 4 and 6 Branching allows branches to point advantageously in different directions around the body of the stake foot. This arrangement increases the grip of the retaining means in the snow. In addition, during the insertion of the stake foot, the friction of branched branches against the wall of the duct drilled in the snowpack is more homogeneous. This avoids carving in the duct continuous grooves that reduce the grip of the branches and their tensile strength.

Figure 5, les branches peuvent porter différents reliefs en bâtonnets 25, en triangles 27 ou en barres 29. Figure 6, les branches 19 portent des reliefs en forme de crans 26 dont une pointe 28 est dirigée vers la base 15. Ces agencements renforcent là encore l'emprise des moyens de retenue, notamment la résistance à l'arrachement. A noter que les reliefs sont portés de préférence sur une seule face des branches pour que, lors du montage en enfilade, les moyens de retenue soient disposés de façon telle que les reliefs ne frottent pas contre la paroi du conduit foré dans le manteau neigeux. Figure 5 the branches may bear different reliefs in rods 25, triangles 27 or bars 29. Figure 6 the branches 19 bear reliefs in the form of notches 26, a point 28 is directed towards the base 15. These arrangements further reinforce the grip of the retaining means, including the tear resistance. Note that the reliefs are preferably worn on one side of the branches so that, during assembly in a row, the retaining means are arranged in such a way that the reliefs do not rub against the wall of the duct drilled in the snowpack.

Figures 7 à 9, les bagues 9 comprennent une base 39 et un logement 31 délimité par une paroi 30. Une ouverture 35 est ménagée dans la base 39 pour le montage par enfilade. L'ouverture 35 débouche dans le logement 31 par un fond 33 qui sert d'appui à la base 15 des moyens de retenue 7, reçue dans ce logement 31. Les bagues 9 comprennent également des encoches 37 formées dans la paroi 30 et ouvertes sur le logement 31 qui permettent aux branches 17, 19 de s'étendre par rapport à la base 39 des bagues 9, vers l'extérieur. Les bagues 9 comprennent enfin des moyens de blocage en rotation les unes par rapport aux autres, portés par la base 39 et, du côté opposé suivant la direction axiale L, par la paroi 30 du logement 31. Ces moyens comprennent des butées 41, 43 pourvues d'entailles 45 et d'ergots 47. Figure 10, les butées à entailles 41, 45 sont disposées du côté du logement 31 et les butées à ergots 43, 47 sont disposées du côté opposé, c'est-à-dire du côté de la base 39. A noter que les ergots et les entailles des butées sont interchangeables d'un côté d'une bague au coté opposé. Dans une même bague, les entailles 45 et les ergots 47 sont distants, suivant la direction axiale L, d'une hauteur H qui contrôle la compression de la base 15 des moyens de retenue, exercée par le moyen de serrage 11, entre le fond 33 du logement d'une bague 9 et la base 39 de la bague suivante le long de l'enfilade. Sur la figure 10, les deux traits en pointillés représentent des rayons perpendiculaires à la direction axiale L et pointant vers un ergot 47 et une entaille 45, distants l'un de l'autre de la hauteur H suivant cette direction axiale L. Pour exercer le contrôle de la compression de la base 15 des moyens de retenue, la hauteur H tient compte de la profondeur P du logement 31 suivant la direction axiale L, comptée entre les moyens de blocage 45 portés par la paroi 30 du logement 31 et le fond 33 de ce logement 31. A noter que le pied de piquet selon l'invention peut comprendre des bagues dont la hauteur H, entre les moyens de blocage 45 portés par la paroi du logement et ceux 47 portés par la base 39 de la bague, est variable pour accommoder des moyens de retenue d'épaisseur variable. Figures 7 to 9 , the rings 9 comprise a base 39 and a housing 31 delimited by a wall 30. An opening 35 is formed in the base 39 for mounting in a row. The opening 35 opens into the housing 31 by a bottom 33 which serves to support the base 15 of the retaining means 7, received in this housing 31. The rings 9 also comprise notches 37 formed in the wall 30 and open on the housing 31 which allow the branches 17, 19 to extend relative to the base 39 of the rings 9, outwardly. The rings 9 finally include locking means in rotation relative to each other, carried by the base 39 and, on the opposite side in the axial direction L, by the wall 30 of the housing 31. These means comprise stops 41, 43 provided with notches 45 and spurs 47. Figure 10 , the notched abutments 41, 45 are arranged on the side of the housing 31 and the pin stops 43, 47 are arranged on the opposite side, that is to say on the side of the base 39. Note that the pins and the Notches abutments are interchangeable on one side of a ring on the opposite side. In the same ring, the notches 45 and the lugs 47 are spaced, in the axial direction L, by a height H which controls the compression of the base 15 of the retaining means, exerted by the clamping means 11, between the bottom 33 of the housing of a ring 9 and the base 39 of the next ring along the row. On the figure 10 , the two dashed lines represent rays perpendicular to the axial direction L and pointing towards a lug 47 and a notch 45, spaced from each other by the height H in this axial direction L. To exert control of the compression of the base 15 of the retaining means, the height H takes into account the depth P of the housing 31 in the axial direction L, counted between the locking means 45 carried by the wall 30 of the housing 31 and the bottom 33 of this housing 31. Note that the stake according to the invention may comprise rings whose height H, between the locking means 45 carried by the housing wall and those 47 carried by the base 39 of the ring, is variable to accommodate retaining means of variable thickness.

Le fond 33 du logement 31 des bagues 9 comprend une surface plane 51 et des surfaces 53 inclinées par rapport à la direction axiale L ou bombées qui déforment la base 15 des moyens de retenue reçue dans ce logement 31 et donnent une inclinaison aux branches par rapport à cette direction axiale en les rapprochant du corps 1 du pied du piquet, comme illustré par la figure 1. De même, la base 39 de la bague 9 comprend une surface plane 55 et des surfaces inclinées par rapport à la direction axiale L ou bombées 57 en correspondance de forme avec les surfaces inclinées ou bombées du fond 33 du logement 31 pour mieux contrôler la compression de la base 15 des moyens de retenue 7 et l'inclinaison des branches 19.The bottom 33 of the housing 31 of the rings 9 comprises a flat surface 51 and surfaces 53 inclined with respect to the axial direction L or curved which deform the base 15 of the retaining means received in this housing 31 and give an inclination to the branches relative to this axial direction by bringing them closer to the body 1 of the foot of the post, as illustrated by the figure 1 . Similarly, the base 39 of the ring 9 comprises a flat surface 55 and surfaces inclined with respect to the axial direction L or curved 57 corresponding in shape with the inclined or curved surfaces of the bottom 33 of the housing 31 to better control the compression of the base 15 of the retaining means 7 and the inclination of the branches 19.

Chaque bague comprend par exemple quatre moyens de blocage 41, 45 portés par la paroi 30 du logement 31 et quatre moyens de blocage 43, 47 portés par la base 39. Les moyens de blocage 41, 45 portés par la paroi 30 du logement 31 sont disposés aux sommets d'un carré et alternent avec quatre encoches 37. Les moyens de blocage 43, 47 portés par la base 39 sont également disposés aux sommets d'un carré et de préférence, alternent avec quatre pans 38 inclinés par rapport à la direction axiale L. Ces pans inclinés 38 sont à l'aplomb des encoches 37 suivant la direction axiale L et concourent au contrôle de la compression de la base 15 des moyens de retenue 7 et de l'inclinaison des branches 19. Dans le mode de réalisation qui vient d'être décrit, les moyens de blocage 41, 45 portés du côté du logement 31 par la paroi 30 sont décalés par rapport aux moyens de blocage 43, 47 portés par la base 39 vis-à-vis desquels ils sont distants de ladite hauteur H suivant la direction axiale L. Les deux traits en pointillés représentent des rayons perpendiculaires à la direction axiale L et pointant vers un ergot 47 et une entaille 45, distants l'un de l'autre de la hauteur H suivant cette direction axiale L. L'angle α de décalage projeté dans un plan perpendiculaire à la direction axiale L, est égal à 45 degrés. La figure 11 montre en éclaté deux bagues se suivant dans l'enfilade autour du corps du pied de piquet et décalées l'une par rapport à l'autre du pas angulaire égal à 45 degrés. Par rapport à un montage en enfilade de bagues ne présentant pas d'angle de décalage, cet agencement multiplie par 2 les orientations angulaires des quatre encoches 37 disposées en carré.Each ring comprises for example four locking means 41, 45 carried by the wall 30 of the housing 31 and four blocking means 43, 47 carried by the base 39. The locking means 41, 45 carried by the wall 30 of the housing 31 are arranged at the vertices of a square and alternate with four notches 37. The locking means 43, 47 carried by the base 39 are also arranged at the vertices of a square and preferably alternate with four sections 38 inclined relative to the axial direction L. These inclined faces 38 are plumb with the notches 37 along the axial direction L and contribute to the control of the compression of the base 15 of the retaining means 7 and the inclination of the branches 19. In the embodiment which has just been described, the locking means 41, 45 carried the side of the housing 31 by the wall 30 are offset relative to the locking means 43, 47 carried by the base 39 with respect to which they are spaced from said height H in the axial direction L. The two dashed lines represent radii perpendicular to the axial direction L and pointing towards a lug 47 and a notch 45, spaced from each other by the height H along this axial direction L. The offset angle α projected in a plane perpendicular to the direc on axial L, is equal to 45 degrees. The figure 11 exploded shows two rings following in the enfilade around the body of the stake foot and offset relative to each other of the angular pitch equal to 45 degrees. Compared to a row assembly of rings having no offset angle, this arrangement multiplies by 2 the angular orientations of the four notches 37 arranged in a square.

Dans l'exemple de réalisation illustré par les figures 12 à 14, l'angle de décalage α est égal à 25 degrés. La figure 15 montre en éclaté deux bagues se suivant dans l'enfilade autour du corps du pied de piquet et décalées l'une par rapport à l'autre du pas angulaire égal à 25 degrés. Dans ce cas, on peut multiplier les orientations angulaires des quatre encoches disposées en carré jusqu'à 18 en utilisant 18 bagues. Ces pas angulaires permettent ainsi de multiplier les orientations angulaires des branches des moyens de retenue et d'augmenter l'emprise du pied de piquet dans le manteau neigeux.In the exemplary embodiment illustrated by the Figures 12 to 14 , the offset angle α is equal to 25 degrees. The figure 15 exploded shows two rings following in the enfilade around the body of the stake foot and offset relative to each other of the angular pitch equal to 25 degrees. In this case, one can multiply the angular orientations of the four notches arranged in square up to 18 by using 18 rings. These angular steps thus make it possible to multiply the angular orientations of the branches of the holding means and to increase the grip of the stake foot in the snowpack.

Le contrôle de la compression permet fabriquer les moyens de retenue dans des plaques d'un matériau flexible dont l'épaisseur est choisie en fonction des propriétés mécaniques du matériau, par exemple un polyuréthane ayant une dureté Shore A égale à 85. Les bagues et le corps du pied de piquet sont fabriqués en métal ou en matériau thermodurcissable. Le pied de piquet des neiges selon l'invention permet avantageusement d'utiliser des bagues toutes identiques et des moyens de retenue tous identiques.The control of the compression makes it possible to manufacture the retaining means in plates of a flexible material whose thickness is chosen according to the mechanical properties of the material, for example a polyurethane having a Shore A hardness equal to 85. The rings and the Stake foot bodies are made of metal or thermosetting material. The snow picket foot according to the invention advantageously allows the use of all identical rings and retaining means all identical.
