Definitions
- the invention relates to improvements to stakes support nets and perch probing snow.
- nets for the marking of runways or nets for the protection of skiers or nets protecting against the wind; these nets are supported by stakes whose main body is made up of a cylindrical rod of revolution that are buried in the ground by a lower end comprising a tip and which comprise at the upper end a knocking head for driving the support post of nets and one or more rings to hang the nets.
- net holder pegs are designed for have good rigidity to withstand the stress related to, inter alia, the efforts of nets such as, for example, the impact of a skier, the effort exercised by a violent wind, or the weight of the snow; they include at the points of attachment security to limit the level of effort applied to the in order to keep his integrity, such as collars that are likely to slide along the stake support of nets or broken rings likely to open if the effort is too important.
- These posts of a length of the order of one and a half meters to two meters are generally cylindrical with a diameter of about twenty millimeters, are made from extruded tubes of aluminum and are equipped with an attached tip its base a cylindrical part, of a substantially equal to the inside diameter of the tube and separated from the tip by a shoulder having substantially the outer diameter of the tube; this tip is designed so that the support post of nets may tear in case of abnormal efforts to avoid its destruction.
- poles of sounding whose main pole body is a rod made from a tube of about twelve millimeters in one piece, or from segments aluminum tubes of the same diameter, the ends of which have threaded male and female parts that allow their butt jointing; survey poles feature at their lower end a kind of half ball ended by a cylindrical base, of a diameter substantially equal to inner diameter of the aluminum tube, which enters the tube with a shoulder of a diameter equal to the outer diameter of the tube.
- the invention consists in improving the performance of the stakes support nets and sounding poles separating the functions at first to improve them intrinsically and then harmonize them.
- the main body of stakes and poles is constituted by a cylindrical rod of revolution composed of threads of glass in one piece over the entire length of the stem, coated with polycondensable polyester resin.

- the net support peg 5 uses to make the main body of stake 1 of preferably a ring of a diameter rather of the order of twenty millimeters from one meter fifty to two meters and rather about fifteen millimeters for stakes net supports of the order of one meter; in effect, one can bend with reasonable effort a rush two meters until its ends form a angle of ninety degrees and without there being degradation of the ring, the latter returning to its linear form initial immediately.
- the lower end of post 7 (fig.1) is composed of a tip 8 which is usually tapered and which is at its base of a diameter greater than that of the main body of stake 1; it is extended by a lower cylindrical sleeve 9 of revolution of a length of the order of two to five centimeters and whose inner diameter is adjusted to outer diameter of the main body of stake 1; the body main post 1 is fixed in the cylindrical sleeve 9 by gluing, which can be for example the polyurethane glue and a lock can ensure assembly; it can be made by a pin 10 traversing diametrically the entire main body of post 1 and the lower cylindrical sleeve 9.
- the diameter the lower cylindrical sleeve 9 being greater than that of the main body of stake 1, it acts as a restraint in the ground at tip 8 while the main body picket itself disposes in its buried part of a certain degree of freedom which is favorable to its ability to elastic deformation.
- the upper end of stake 11 is simplified compared to that of the net support peg aluminum and in particular it is no longer essential to use necklaces that can slide along the main body of the net support post as well as broken rings since it is the main body that absorbs the efforts ; as a result, the upper end of post 11 consists of a striking head 12 of a diameter greater than the diameter of the main body of stake 1 connected by an intermediate cylindrical portion 13 to a upper cylindrical sleeve 14 of revolution of a length of the order of two to five centimeters and whose diameter inside is adjusted to the diameter of the main body of stake 1; the main body of stake 1 is fixed in the sleeve cylindrical upper 14 by gluing, which can be, by example, polyurethane glue and a lock can ensure assembly; it can be realized by a pin 15 diametrically crossing the entire main body of post 1 and the upper cylindrical sleeve 14; rings fastening nets are attached to atria 16 (fig.2) secured to the upper cylindrical sleeve 14 and

Abstract
Description
L'invention concerne des perfectionnements aux piquets supports de filets et aux perches de sondage de la neige.The invention relates to improvements to stakes support nets and perch probing snow.
Dans les stations de sport d'hiver, on utilise toutes sortes de filets comme, par exemple, des filets pour le balisage des pistes ou des filets pour la protection des skieurs ou des filets de protection contre le vent ; ces filets sont soutenus par des piquets dont le corps principal est constitué d'une tige cylindrique de révolution qui sont enfoncés dans le sol par une extrémité inférieure comportant une pointe et qui comportent à l'extrémité supérieure une tête à frapper permettant d'enfoncer le piquet support de filets et un ou plusieurs anneaux permettant d'accrocher les filets. Ces piquets supports de filets sont conçus pour présenter une bonne rigidité afin de résister aux contraintes d'environnement liées, notamment, aux efforts supportés par les filets comme, par exemple, l'impact d'un skieur, l'effort exercé par un vent violent, ou le poids de la neige ; ils comportent au niveau des points d'accroche des sécurités permettant de limiter le niveau des efforts appliqués au poteau, afin de lui garder son intégrité, tels que des colliers qui sont susceptibles de glisser le long du piquet support de filets ou des anneaux brisés susceptibles de s'ouvrir si l'effort est trop important. Ces poteaux, d'une longueur de l'ordre d'un mètre et demi à deux mètres sont généralement cylindriques d'un diamètre de l'ordre de vingt millimètres, sont réalisés à partir de tubes extrudés d'aluminium et sont munis d'une pointe rapportée comportant à sa base une partie cylindrique, d'un diamètre sensiblement égal au diamètre intérieur du tube et séparée de la pointe par un épaulement ayant sensiblement le diamètre extérieur du tube ; cette pointe est conçue pour que le piquet support de filets puisse s'arracher en cas d'efforts anormaux pour éviter sa destruction.In winter sports resorts, we use all kinds of nets such as nets for the marking of runways or nets for the protection of skiers or nets protecting against the wind; these nets are supported by stakes whose main body is made up of a cylindrical rod of revolution that are buried in the ground by a lower end comprising a tip and which comprise at the upper end a knocking head for driving the support post of nets and one or more rings to hang the nets. These net holder pegs are designed for have good rigidity to withstand the stress related to, inter alia, the efforts of nets such as, for example, the impact of a skier, the effort exercised by a violent wind, or the weight of the snow; they include at the points of attachment security to limit the level of effort applied to the in order to keep his integrity, such as collars that are likely to slide along the stake support of nets or broken rings likely to open if the effort is too important. These posts, of a length of the order of one and a half meters to two meters are generally cylindrical with a diameter of about twenty millimeters, are made from extruded tubes of aluminum and are equipped with an attached tip its base a cylindrical part, of a substantially equal to the inside diameter of the tube and separated from the tip by a shoulder having substantially the outer diameter of the tube; this tip is designed so that the support post of nets may tear in case of abnormal efforts to avoid its destruction.
La recherche des personnes ensevelies dans les coulées de neige se fait notamment en utilisant des perches de sondage, dont le corps principal de perche est une tige réalisée, soit à partir d'un tube d'un diamètre d'environ douze millimètres d'un seul tenant, soit à partir de segments de tubes en aluminium de même diamètre, dont les extrémités comportent des pièces filetées mâle et femelle qui permettent leur assemblage bout à bout ; les perches de sondage comportent à leur extrémité inférieure une sorte de demi boule terminée par une base cylindrique, d'un diamètre sensiblement égal au diamètre intérieur du tube aluminium, qui pénètre dans le tube avec un épaulement d'un diamètre égal au diamètre extérieur du tube.Search for people buried in the flows of snow is made in particular by using poles of sounding, whose main pole body is a rod made from a tube of about twelve millimeters in one piece, or from segments aluminum tubes of the same diameter, the ends of which have threaded male and female parts that allow their butt jointing; survey poles feature at their lower end a kind of half ball ended by a cylindrical base, of a diameter substantially equal to inner diameter of the aluminum tube, which enters the tube with a shoulder of a diameter equal to the outer diameter of the tube.
Il apparaít que les tubes aluminium utilisés aussi bien pour réaliser des piquets supports de filets que pour les perches de sondage, tels que ceux décrits dans le document FR-A-2 560 267 ont une limite élastique faible et qu'ils subissent fréquemment des déformations permanentes qui les rendent inopérants ; lorsque les dispositifs de protection permettant de protéger les piquets supports de filets ont fonctionné, il est nécessaire de faire intervenir du personnel pour les remettre en service ; les déformations peuvent provenir, pour les piquets supports de filets, des engins de damage qui passent sur les filets et pour les perches de sondage de bloc de neige plus dure qui devient l'extrémité inférieure de la perche de sondage et déforment cette dernière de manière permanente.It appears that the aluminum tubes used both for make stakes support nets that for the poles of survey, such as those described in document FR-A-2 560 267 have a low elastic limit and that they undergo frequent permanent deformities that render them inoperative; when the protective devices to protect the stakes net holders have worked, it is necessary to involve staff to return them to service; the deformations may come, for the stakes supports nets, grooming gear passing over the nets and for the harder snow block probing poles that becomes the lower end of the sounding boom and deform the latter permanently.
On connaít la technique de fabrication de pièces composites qui consiste à pulltruder en continu de la fibre minérale comme de la fibre de verre et de l'enduire d'un liant constitué, par exemple, d'une matière plastique polycondensable avant de l'introduire dans un conformateur, de manière à donner un profil constant à l'ensemble, tout en procédant à son réchauffage pour provoquer le durcissement. Les pièces ainsi fabriquées sont quasiment inaltérables et permettent une déformation élastique importante tout en ayant une excellente résistance à la déformation. Cette technique est couramment utilisée pour la fabrication des cannes à pêche ou des piquets de palissade tels que ceux décrits dans le document FR-A-2 584 933.We know the technique of manufacturing composite parts which consists of continuously pulltruding mineral fiber as fiberglass and to coat it with a binder consisting of example, of a polycondensable plastic before introduce it into a shaper, so as to give a profile constant to the whole while reheating it for cause hardening. The pieces thus manufactured are almost unalterable and allow elastic deformation important while having excellent resistance to deformation. This technique is commonly used for manufacture of fishing rods or picket poles such as than those described in FR-A-2 584 933.
L'invention consiste à améliorer les performances des piquets supports de filets et des perches de sondage en séparant les fonctions dans un premier temps pour les améliorer intrinsèquement et ensuite les harmoniser entre elles.The invention consists in improving the performance of the stakes support nets and sounding poles separating the functions at first to improve them intrinsically and then harmonize them.
Dans ce but et conformément aux revendications 1 et 5, le
corps principal des piquets et des perches est constitué par une
tige cylindrique de révolution composée de fils de
verre d'un seul tenant sur toute la longueur de la tige,
enduits de résine polyester polycondensable.For this purpose and in accordance with
Sur les dessins :
L'invention consiste à remplacer le corps principal de
piquet 1 (fig.1 et 2) ou le corps principal de perche 2
(fig.3 et 4), constitué initialement d'un tube d'aluminium,
par une tige cylindrique de révolution obtenue par
pulltrusion, composée de fils de verre d'un seul tenant sur
toute la longueur de la tige, qui sont enduits de préférence
de résine de polyester polycondensable. Cette tige se
présente sous forme soit de tube à paroi épaisse 3 (fig.3)
soit de jonc 4 (fig.1) en fonction des caractéristiques
recherchées ; le tube à paroi épaisse 3, est utilisé de
préférence pour les perches sondage tandis que les joncs 4
sont utilisés de préférence pour réaliser les piquets
supports de filets ; la tige cylindrique utilisée a un
diamètre extérieur qui est de l'ordre de quinze à vingt
millimètres et lorsqu'elle est formée d'un tube à paroi
épaisse 3, l'épaisseur de la paroi est de l'ordre de quinze à
vingt pour cent du diamètre extérieur du tube à paroi épaisse
3. Dans ce qui suit on va d'abord en déduire les conséquences
dans la conception d'un piquet support de filet 5 (fig.1 et
2) puis on fait la même chose pour une perche de sondage 6
(fig.3 et 4).The invention consists in replacing the main body of
stake 1 (fig.1 and 2) or the main body of pole 2
(fig.3 and 4), initially consisting of an aluminum tube,
by a cylindrical rod of revolution obtained by
pulltrusion, composed of glass threads in one piece on
the entire length of the stem, which are preferably coated
polycondensable polyester resin. This stem
present in the form of either thick-walled tube 3 (FIG.
either of rod 4 (fig.1) according to the characteristics
sought; the thick-walled tube 3, is used
preference for survey poles while
En ce qui concerne le piquet support de filet 5 on
utilise pour réaliser le corps principal de piquet 1 de
préférence un jonc d'un diamètre plutôt de l'ordre de vingt
millimètres allant d'un mètre cinquante à deux mètres et
plutôt de l'ordre de quinze millimètres pour des piquets
supports de filets de longueur de l'ordre du mètre ; en
effet, on peut courber moyennant un effort raisonnable un
jonc de deux mètres jusqu'à ce que ses extrémités forment un
angle de quatre vingt dix degrés et sans qu'il y ait de
dégradation du jonc, ce dernier retrouvant sa forme linéaire
initiale immédiatement. En revanche, l'effort nécessaire pour
faire la même chose avec un jonc d'un mètre et vingt
millimètres de diamètre demande des efforts beaucoup plus
importants qui peuvent provoquer la dégradation du jonc
tandis qu'en utilisant un jonc d'un diamètre plus faible, qui
peut être de l'ordre de quinze millimètres, on retrouve à
échelle plus réduite, les mêmes caractéristiques que celles
du jonc de deux mètres et vingt millimètres de diamètre.
L'extrémité inférieure de piquet 7 (fig.1) est composée d'une
pointe 8 qui est généralement conique et qui est à sa base
d'un diamètre supérieur à celui du corps principal de piquet
1 ; elle est prolongée par un manchon cylindrique inférieur 9
de révolution d'une longueur de l'ordre de deux à cinq
centimètres et dont le diamètre intérieur est ajusté au
diamètre extérieur du corps principal de piquet 1 ; le corps
principal de piquet 1 est fixé dans le manchon cylindrique
inférieur 9 par collage, qui peut être par exemple de la
colle polyuréthane et un verrouillage peut assurer
l'assemblage ; il peut être réalisé par une goupille 10
traversant diamétralement l'ensemble du corps principal de
piquet 1 et du manchon cylindrique inférieur 9. Le diamètre
du manchon cylindrique inférieur 9 étant supérieur à celui du
corps principal de piquet 1, il agit comme une retenue dans
le sol au niveau de la pointe 8 tandis que le corps principal
de piquet lui-même dispose dans sa partie enterrée d'un
certain degré de liberté qui est favorable à sa capacité de
déformation élastique. L'extrémité supérieure de piquet 11
est simplifiée par rapport à celle du piquet support de filet
en aluminium et notamment il n'est plus indispensable
d'utiliser des colliers susceptibles de glisser le long du
corps principal du piquet support de filet ainsi que des
anneaux brisés puisque c'est le corps principal qui absorbe
les efforts ; en conséquence, l'extrémité supérieure de
piquet 11 est constituée d'une tête à frapper 12 d'un
diamètre supérieur au diamètre du corps principal de piquet 1
reliée par une partie cylindrique intermédiaire 13 à un
manchon cylindrique supérieur 14 de révolution d'une longueur
de l'ordre de deux à cinq centimètres et dont le diamètre
intérieur est ajusté au diamètre du corps principal de piquet
1 ; le corps principal de piquet 1 est fixé dans le manchon
cylindrique supérieur 14 par collage, qui peut être, par
exemple, de la colle polyuréthane et un verrouillage peut
assurer l'assemblage ; il peut être réalisé par une goupille
15 traversant diamétralement l'ensemble du corps principal de
piquet 1 et du manchon cylindrique supérieur 14 ; les anneaux
de fixation des filets sont fixés à des oreillettes 16
(fig.2) solidaires du manchon cylindrique supérieure 14 et/ou
à des anneaux de fixation 17 (fig.1) articulés dans des trous
18 traversant diamétralement la partie cylindrique
intermédiaire 13. Les pièces en aluminium placées aux
extrémités inférieure 7 et supérieure 11 peuvent être
réalisées principalement en aluminium moulé. En ce qui
concerne les perches de sondage elles sont de préférence
constituées d'un corps principal de perche 2 constitué d'un
tube à paroi épaisse 3 (fig.3) d'un diamètre de l'ordre de
quinze millimètres avec une épaisseur de paroi de l'ordre de
deux millimètres et demi ; une première extrémité inférieure
de perche 19 comporte une pointe formée d'une première face
arrondie 20 convexe, reliée à une première surface latérale
21 en forme de cylindre de révolution de faible hauteur et de
diamètre légèrement supérieur au diamètre du corps principal
de perche 2 qui peut être de l'ordre de un à deux
millimètres ; cette dernière est elle-même reliée à une
deuxième surface arrondie 22 orientée en opposition par
rapport à la première face arrondie 20 ; ces trois surfaces
20,21 et 22 ayant un axe de symétrie 23 commun ; la deuxième
surface arrondie 22 comporte dans sa partie centrale une
première tige cylindrique 24 de révolution de quelques
centimètres de long et de diamètre sensiblement égal au
diamètre intérieur du tube à paroi épaisse 3 ; la première
tige cylindrique 24 est reliée à un premier épaulement
annulaire 25 dont le diamètre extérieur est le diamètre
extérieur du tube à paroi épaisse 3. La première tige
cylindrique 24 sert à la fixation de la première extrémité
inférieure de perche 19 dans le corps principal de perche 2 ;
elle est introduite dans l'extrémité du tube à paroi épaisse
3 et elle y est collée par une colle qui peut être une colle
polyuréthane ; dans une variante de l'invention, la première
tige cylindrique 24 comporte à intervalles réguliers des
gorges annulaires 26 qui facilitent la fixation par collage
de la première tige cylindrique 24 en assurant une meilleure
répartition de la colle ; dans une autre variante de
l'invention, l'assemblage est verrouillé par une goupille
traversant l'extrémité inférieure du corps principal de
perche 2 et la première tige cylindrique 24. La forme de la
première extrémité inférieure de perche 19 permet de réaliser
un trou plus large que le diamètre du corps principal de
perche 2 ce qui facilite le coulissement de la perche de
sondage 6 à l'enfoncement et au retrait ; la deuxième surface
arrondie 22 présente, au niveau de sa jonction avec le corps
principal de perche 2, une rampe qui permet, lorsqu'on retire
la perche de sondage 6 de son trou, une évacuation régulière
de la neige.Regarding the
Dans une variante de l'invention, dans le but de
faciliter l'enfoncement de la perche de sondage 6, une
deuxième extrémité inférieure de perche 27 (fig.4) est formée
de deux éléments semblables à celui que l'on vient de décrire
qui sont placés en série sur le même axe de révolution : la
deuxième extrémité inférieure de perche 27 comporte une
troisième surface arrondie 28 convexe, de forme semblable à
celle de la première surface arrondie 20 convexe, limitée
extérieurement comme précédemment par une deuxième surface
latérale 29 cylindrique de révolution de faible hauteur d'un
diamètre de préférence identique au diamètre de la première
surface latérale 21 ; cette surface latérale 29 limite
extérieurement une quatrième surface arrondie convexe 30, qui
est en opposition par rapport à la troisième surface arrondie
28, qui se raccorde intérieurement sur une troisième surface
latérale 31 cylindrique de faible hauteur d'un diamètre
sensiblement égal au diamètre intérieur du corps principal de
perche 2 ; l'autre extrémité de la troisième surface latérale
31 limite intérieurement une cinquième surface arrondie 32
convexe limitée extérieurement par une quatrième surface
latérale 33 cylindrique de révolution de faible hauteur et
d'un diamètre légèrement supérieur à celui de la deuxième
surface latérale 29; enfin une sixième surface arrondie 34
convexe en opposition avec la cinquième surface arrondie 32
convexe est reliée à une deuxième tige cylindrique, pouvant
comporter des gorges annulaires et un deuxième épaulement
identiques à la première tige cylindrique 24 et au premier
épaulement 25 précédemment décrits. Si la perche de sondage 6
est en plusieurs segments la liaison entre les segments est
réalisée comme pour les perches de sondage en aluminium avec
des embouts mâle et femelle vissés entre eux. Lorsque le
corps principal de perche 6 a un diamètre de quinze
millimètres, la deuxième surface latérale 29 a un diamètre de
quinze millimètres et la quatrième surface latérale 33 a un
diamètre de seize millimètres.In a variant of the invention, for the purpose of
facilitate the insertion of the sounding
Dans ce qui précède, la description concerne l'emploi de fibres de verre pour la fabrication des joncs et des tubes à paroi épaisse destinés à réaliser des piquets et des perches de sondage ; il est évident que les fils de verre peuvent être remplacés par tous fils synthétiques d'origine minérale ou organique telle que la fibre de carbone dont l'amplitude du domaine de déformation élastique par étirage est sensiblement celui des fils de verre ainsi les niveaux d'effort correspondants. Pour compenser les écarts de résistance à la déformation élastique constatés, il est possible de changer les diamètres et épaisseurs de tube ou le diamètre des joncs afin de solliciter plus ou moins, au niveau de leur étirage élastique, les fils synthétiques qui les composent en fonction du résultat recherché.In the foregoing, the description relates to the use of fiberglass for the manufacture of rods and tubes thick wall for making stakes and poles survey; it's obvious that glass wires can to be replaced by all synthetic threads of mineral origin or organic such as carbon fiber whose amplitude of the elastic deformation domain by stretching is substantially that of the glass threads so the levels corresponding effort. To compensate for differences resistance to elastic deformation found, it is possible to change the diameters and thicknesses of tube or the diameter of the rods to solicit more or less, at level of their elastic stretching, the synthetic threads that compose them according to the desired result.
