Definitions
- the invention relates to the anchoring, in the ground, of poles or stakes, by means of a dowel having a rigid part, advantageously composed of metal plates shaped into fins, said rigid part forming a sheath intended to receive, once the dowel is sunk into the ground, the base of the post or stake.
- this tool allows you to push the dowel well into the ground, without deforming it and without letting the earth penetrate its sheath.
- the invention relates to a tool of the aforementioned type, which offers a particularly high impact resistance and also allows easy replacement of the most fragile elements in the event of wear or breakage.
- the central part of said elongated body comprises: an upper portion of larger section capped by a bell-shaped part provided with a central passage for the upper part of the elongated body and whose upper surface forms said striking surface; and a lower portion whose section has a dimension equal to the circle inscribed in the horizontal section of the ankle sleeve, said lower portion being surrounded by a flat piece whose lower surface constitutes said bearing surface and whose upper surface is connected to the base of said bell.
- the lower part or pin of said elongated body comprises a lower end portion whose section has a dimension substantially equal to that of the ankle sheath and having a pointed end and an upper portion connected to said lower portion of the central part and of reduced section.
- the whole of said elongated body including its upper part or handle, its central part with its two different sections corresponding to two distinct cylindrical portions or to a single frustoconical portion, and its lower part, provided a portion of reduced section and a pointed end portion or "plug", consists of a single piece, advantageously by foundry or forging, while the striking bell and the flat support piece are patches.
- the handles of the ram have a lower end secured to the body of the sleeve, preferably by a long longitudinal weld, while their upper curved end freely penetrates into a longitudinal channel which opens to the surface d the upper end of the sleeve and has a depth greater than the length of the handle portion which penetrates therein.
- the elongated body of the tool constituted, in the preferred embodiment described, in a single piece of foundry, a process which allows a body to be produced inexpensively in which the longitudinal fibers metal (steel for example) are preserved and thus offer a great resistance to tearing, includes: a cylindrical handle 1, having for example 30 mm in diameter and 900 mm long; a central part 2, composed of a cylindrical upper portion 20 having for example 50 mm in diameter and a cylindrical lower portion 21 having 50 mm in height and for example 35 mm in diameter, which corresponds substantially to the dimension of the circle most commonly used ankle scabbard entry; and a spindle 3, composed of a pointed bottom plug 32 having a height of 190 mm and a section of the same section as the ankle sheaths and of an upper portion 31, 260 mm in height and of reduced diameter equal to 28 mm in the example considered.
- the upper portion 20 of the central part is capped with a bell 4 having for example an outer diameter of 80 mm and a height of 65 mm and fitting exactly on said upper portion 20, a central passage 41 allowing the crossing of its upper striking surface 42 by the handle 1.
- the bell rests at its base on the upper surface of a flat piece 5, 30 mm thick provided with a central circular preservation recess 51 having for example 60 mm diameter, and through which the portion 21 passes coaxially.
- the lower surface 52 of the flat part 5 serves as a bearing surface and its largest dimension is for example equal to 250 mm.
- this bearing surface is not circular, but comprises for example one of the forms lightened by recesses 57, 58 illustrated by FIGS. 4 and 5, where it can also be seen that the bearing part 5 is provided with reinforcing fins, such as 53 to 56, integral with the striking bell 4, while the bearing surface is provided with one or more longitudinal notches, such as 59, which facilitate the positioning on the ankle fins.
- the shape of the bearing surface will be adapted to the geometric configuration of the set of fins.
- the central protruding part 2 has significant mechanical strength and makes it possible to constitute, on the one hand a fitting element 20 for the striking bell 4, on the other hand, a portion 21 which cooperates with the plug 32 for ensure the relative guiding of the dowel and the false stake.
- the use of the striking bell makes it possible to increase the section of the striking surface with which the base of the ram cooperates, without thereby excessively increasing the section of the body of the tool, which must be as light as possible.
- the plug 32 has, over its entire height, with the exception of the pointed part, a section such that it conforms perfectly to that of the ankle sheath, to within a few tenths of a mm, and lubrication is recommended to facilitate removal of the tool at the end of the driving operation.
- the very small thickness of the clearance prevents the penetration of the earth during sinking.
- the intermediate reduced section 31 reduces the risk of the false stake sticking to the sheath.
- the support piece 5, the bell 4 and even the central guide portion 21 and the plug 32 can be removably mounted (by screwing, or fitting) so as to be changed in the event of wear or breakage, or again, as regards the plug and the central guide portion, with a view to using the same tool for dowels having sheaths of different sections.
- the central part 2 it is possible to give the central part 2 the shape of a truncated cone whose upper base will have a diameter of 50 mm for example and the lower base, a diameter of 35 mm.
- the section of this central part will then have no discontinuity and its lower base will also be connected without section discontinuity with a frustoconical upper part of the spindle 3.
- the flat part 5 will not, in this variant, have a central recess such as 51 figure 1, but will be directly fitted on the central part 2.
- the frustoconical central part 2 by engaging at the start in the sheath of the ankle, will wedge the latter and, from the first shocks of the ram, the ankle will be flared by going up along the frustoconical central part 2, which will facilitate the introduction of the post at the end of the operation. No risk of crimping the ankle sheath exists.
- the ram has a cylindrical sleeve 6 having for example 600 mm long, an outside diameter of 80 mm (equal to that of the striking surface 42) and an inside diameter of 31 mm (therefore , slightly higher than that of handle 1 on which it slides).
- the relatively large height and the relatively small section of the ram give better sliding guidance with a greater stroke, and a very centered impact on the striking surface.
- four handles 7, 8, 9, 10 are provided, arranged with a uniform distribution at the periphery of the sleeve 6 and secured to the latter at only one of their ends. Indeed, it was found that the joining of the handle at its two ends would cause rigidity such that shock waves would break the junctions after a certain operating time.
- the attachment of the handle is made at its lower part, by a longitudinal weld 71, which offers a very high resistance to tearing by the shock wave which arises nearby.
- the upper part of the handles is left free, which allows the dissipation of the shock wave; to avoid, however, secondary parasitic vibrations and deformations, this upper part is curved at a level higher than that of the upper end of the sleeve and its end descends to penetrate with a very small clearance in a channel 72 formed in the body of the sleeve annular and opening to the transverse outer surface thereof.
- a gap 73 is provided between the end surface of the handle and the bottom of the channel.
- the tool of the invention cannot be used exclusively with the dowel described in the above-mentioned certificate of addition and patent, although it has been more particularly designed to adapt to it.

Abstract
Description
L'invention se rapporte à l'ancrage, dans le sol, de poteaux ou de piquets, au moyen d'une cheville ayant une pièce rigide, avantageusement composée de plaques métalliques conformées en ailettes, ladite pièce rigide formant un fourreau destiné à recevoir, une fois la cheville enfoncée dans le sol, la base du poteau ou du piquet.The invention relates to the anchoring, in the ground, of poles or stakes, by means of a dowel having a rigid part, advantageously composed of metal plates shaped into fins, said rigid part forming a sheath intended to receive, once the dowel is sunk into the ground, the base of the post or stake.
Pour enfoncer de telles chevilles dans le sol, on a proposé, dans le premier certificat d'addition au brevet français n° 7811279, certificat déposé le 10 Avril 1979 sous le n° 7909679, par le Demandeur et ayant pour titre:
- »Cheville destinée à la fixation dans le sol de poteaux ou piquets et dispositif servant à l'enfoncement de cette cheville«,
d'utiliser un outil comportant un corps allongé rigide et un manchon formant bélier, monté coulissant sur la partie supérieure dudit corps allongé pour venir coopérer avec une surface transversale supérieure plane d'une rondelle centrale que comporte ledit corps allongé, tandis qu'une surface transversale inférieure de ladite rondelle, située à une distance de l'extrémité inférieure dudit corps allongé légèrement supérieure à la hauteur de la cheville, prend appui par sa partie périphérique sur ladite pièce rigide et est munie d'un évidement central. Avec un tel outil, l'opération d'enfoncement d'une cheville s'effectue en introduisant, dans le fourreau de celle-ci, alors qu'elle est simplement posée sur le sol en position verticale, la partie inférieure du corps de l'outil, qui joue ainsi le rôle d'un faux piquet, sur une longueur légèrement supérieure à la hauteur de la cheville, de façon que l'extrémité inférieure du corps de l'outil pénètre légèrement dans le sol. On fait alors coulisser le bélier, muni à cet effet de poignées de manœuvre, sur la partie supérieure du corps de l'outil, de façon à imprimer des chocs répétés sur ladite surface transversale supérieure ou surface de frappe. La surface transversale inférieur ou surface d'appui transmet les chocs au bord supérieur des ailettes de la cheville et enfonce celle-ci dans le sol suivant l'axe général de l'outil avec guidage par la partie supérieure du corps de l'outil. Lorsqu'on a enfoncé la cheville complètement dans le sol, on retire le faux piquet et on introduit un piquet dans le fourreau de la cheville, jusqu'à ce que sa base pénètre légèrement dans le sol, à la profondeur atteintre par l'extrémité inférieure du faux piquet. Au cours de l'enfoncement de la cheville, l'évidement central de la surface d'appui de l'outil préserve le fourreau de la cheville d'un sertissage qui empêcherait la mise en place ultérieure du piquet.To drive such pegs into the ground, the first certificate of addition to the French patent No. 7811279, proposed on April 10, 1979 under No. 7909679, was proposed by the Applicant and having as its title:
- "Anchor intended for fixing posts or pegs in the ground and device used to drive this anchor",
using a tool comprising a rigid elongated body and a ram-forming sleeve, slidably mounted on the upper part of said elongated body to come to cooperate with a planar upper transverse surface of a central washer that comprises said elongated body, while a surface lower transverse of said washer, located at a distance from the lower end of said elongated body slightly greater than the height of the ankle, bears by its peripheral part on said rigid part and is provided with a central recess. With such a tool, the operation of driving in an ankle is carried out by introducing, into the sheath thereof, while it is simply placed on the ground in a vertical position, the lower part of the body of the tool, which thus plays the role of a false stake, over a length slightly greater than the height of the dowel, so that the lower end of the body of the tool penetrates slightly into the ground. The ram is then made to slide, provided for this purpose with operating handles, on the upper part of the body of the tool, so as to impart repeated shocks to said upper transverse surface or striking surface. The lower transverse surface or bearing surface transmits shocks to the upper edge of the ankle fins and drives the latter into the ground along the general axis of the tool with guidance from the upper part of the tool body. When the ankle has been fully inserted into the ground, the false stake is removed and a stake is inserted into the ankle sheath, until its base penetrates slightly into the ground, to the depth reached by the end lower of the false stake. During the insertion of the dowel, the central recess of the support surface of the tool preserves the sheath of the dowel from crimping which would prevent the subsequent placement of the stake.
En définitive, cet outil permet de bien enfoncer la cheville dans le sol, sans la déformer et sans laisser la terre pénétrer dans son fourreau.Ultimately, this tool allows you to push the dowel well into the ground, without deforming it and without letting the earth penetrate its sheath.
Il présente toutefois une difficulté de réalisation due au fait que l'exercice de chocs violents entraîne un risque de casse important, en particulier au niveau de la protubérance centrale du corps ou des jonctions des poignées avec le bélier.However, it presents a difficulty of realization due to the fact that the exercise of violent shocks involves a significant risk of breakage, in particular at the level of the central protuberance of the body or of the junctions of the handles with the ram.
L'invention a pour objet un outil du genre susvisé, qui offre une résistance aux chocs particulièrement élevée et permet par ailleurs le remplacement facile des éléments les plus fragiles en cas d'usure ou de bris.The invention relates to a tool of the aforementioned type, which offers a particularly high impact resistance and also allows easy replacement of the most fragile elements in the event of wear or breakage.
Suivant la caractéristique principale de l'invention, la partie centrale dudit corps allongé comporte: une portion supérieure de plus grande section coiffée par une pièce en forme de cloche munie d'un passage central pour la partie supérieure du corps allongé et dont la surface supérieure forme ladite surface de frappe; et une portion inférieure dont la section a une dimension égale au cercle inscrit dans la section horizontale du fourreau de la cheville, ladite portion inférieure étant entourée d'une pièce plate dont la surface inférieure constitue ladite surface d'appui et dont la surface supérieure est raccordée à la base de ladite cloche.According to the main characteristic of the invention, the central part of said elongated body comprises: an upper portion of larger section capped by a bell-shaped part provided with a central passage for the upper part of the elongated body and whose upper surface forms said striking surface; and a lower portion whose section has a dimension equal to the circle inscribed in the horizontal section of the ankle sleeve, said lower portion being surrounded by a flat piece whose lower surface constitutes said bearing surface and whose upper surface is connected to the base of said bell.
Suivant une autre caractéristique de l'invention, la partie inférieure ou broche dudit corps allongé comporte une portion d'extrémité inférieure dont la section a une dimension sensiblement égale à celle du fourreau de la cheville et ayant une extrémité appointée et une portion supérieure raccordée à ladite portion inférieure de la partie centrale et de section réduite.According to another characteristic of the invention, the lower part or pin of said elongated body comprises a lower end portion whose section has a dimension substantially equal to that of the ankle sheath and having a pointed end and an upper portion connected to said lower portion of the central part and of reduced section.
Suivant un mode d'exécution préféré, l'ensemble dudit corps allongé, y compris sa partie supérieure ou manche, sa partie centrale avec ses deux sections différentes correspondant à deux portions cylindriques distinctes ou à une seule portion tronconique, et sa partie inférieure, munie d'une portion de section réduite et d'une portion d'extrémité appointée ou »bouchon«, est constitué d'une seule pièce, avantageusement par fonderie ou forgeage, tandis que la cloche de frappe et la pièce plate d'appui sont des pièces rapportées.According to a preferred embodiment, the whole of said elongated body, including its upper part or handle, its central part with its two different sections corresponding to two distinct cylindrical portions or to a single frustoconical portion, and its lower part, provided a portion of reduced section and a pointed end portion or "plug", consists of a single piece, advantageously by foundry or forging, while the striking bell and the flat support piece are patches.
Suivant une caractéristique supplémentaire importante de l'invention, les poignées du bélier ont une extrémité inférieure solidarisée au corps du manchon, de préférence par une longue soudure longitudinale, tandis que leur extrémité supérieure recourbée pénètre librement dans un canal longitudinal qui débouche à la surface d'extrémité supérieure du manchon et a une profondeur supérieure à la longueur de la portion de poignée qui y pénètre.According to an important additional characteristic of the invention, the handles of the ram have a lower end secured to the body of the sleeve, preferably by a long longitudinal weld, while their upper curved end freely penetrates into a longitudinal channel which opens to the surface d the upper end of the sleeve and has a depth greater than the length of the handle portion which penetrates therein.
D'autres particularités, ainsi que les avantages de l'invention, apparaîtront clairement à la lumière de la description ci-après.Other features, as well as the advantages of the invention, will become apparent in the light of the description below.
Au dessin annexé:
- La figure 1 est une vue en coupe longitudinale du corps allongé d'un outil conforme à un mode d'exécution préféré de l'invention, dont
- la figure 2 montre le bélier, également en coupe longitudinale;
- la figure 3 montre ledit bélier en coupe transversale; et
- les figures 4 et 5 montrent, en perspective, deux modes d'exécution de la cloche de frappe et de la pièce d'appui.
- Figure 1 is a longitudinal sectional view of the elongated body of a tool according to a preferred embodiment of the invention, of which
- Figure 2 shows the ram, also in longitudinal section;
- Figure 3 shows said ram in cross section; and
- Figures 4 and 5 show, in perspective, two modes of execution of the striking bell and the support piece.
On voit, à la figure 1, que le corps allongé de l'outil, constitué, dans le mode d'exécution préféré décrit, en une seule pièce de fonderie, procédé qui permet de réaliser à bon marché un corps dans lequel les fibres longitudinales du métal (l'acier par exemple) sont préservées et offrent ainsi une grande résistance à l'arrachement, comprend: un manche cylindrique 1, ayant par exemple 30 mm de diamètre et 900 mm de long; une partie centrale 2, composée d'une portion supérieure cylindrique 20 ayant par exemple 50 mm de diamètre et d'une portion inférieure cylindrique 21 ayant 50 mm de hauteur et par exemple 35 mm de diamètre, ce qui correspond sensiblement à la dimension du cercle inscrit de la section du fourreau de la cheville la plus couramment utilisée; et une broche 3, composée d'un bouchon inférieur appointé 32 ayant une hauteur de 190 mm et une section de même section que les fourreau de la cheville et d'une portion supérieure 31, de 260 mm de hauteur et de diamètre réduit égal à 28 mm dans l'exemple considéré.It can be seen, in FIG. 1, that the elongated body of the tool, constituted, in the preferred embodiment described, in a single piece of foundry, a process which allows a body to be produced inexpensively in which the longitudinal fibers metal (steel for example) are preserved and thus offer a great resistance to tearing, includes: a cylindrical handle 1, having for example 30 mm in diameter and 900 mm long; a
La portion supérieure 20 de la partie centrale est coiffée d'une cloche 4 ayant par exemple un diamètre extérieur de 80 mm et une hauteur de 65 mm et s'emboîtant exactement sur ladite portion supérieure 20, un passage central 41 permettant la traversée de sa surface supérieure de frappe 42 par le manche 1. La cloche se repose à sa base sur la surface supérieure d'une pièce plate 5, de 30 mm d'épaisseur munie d'un évidement central circulaire de préservation 51 ayant par exemple 60 mm de diamètre, et à travers lequel la portion 21 passe coaxialement.The
La surface inférieure 52 de la pièce plate 5 sert de surface d'appui et sa plus grande dimension est par exemple égale à 250 mm.The
Avantageusement, cette surface d'appui n'est pas circulaire, mais comporte par exemple l'une des formes allégées par des évidements 57, 58 illustrés par les figures 4 et 5, où l'on voit également que la pièce d'appui 5 est munie d'ailettes de renfort, telles que 53 à 56, solidaires de la cloche de frappe 4, tandis que la surface d'appui est munie d'une ou plusieurs encoches longitudinales, telles que 59, qui facilitent la mise en place sur les ailettes de la cheville. Bien entendu, la forme de la surface d'appui sera adaptée à la configuration géométrique de l'ensemble d'ailettes.Advantageously, this bearing surface is not circular, but comprises for example one of the forms lightened by
On notera que la partie centrale en protubérance 2a une résistance mécanique importante et permet de constituer, d'une part un élément d'emboîtement 20 pour la cloche de frappe 4, d'autre part, une portion 21 qui coopère avec le bouchon 32 pour assurer le guidage relatif de la cheville et du faux piquet.It will be noted that the central protruding
L'utilisation de la cloche de frappe permet d'augmenter la section de la surface de frappe avec laquelle coopère la base du bélier, sans pour cela augmenter excessivement la section du corps de l'outil, lequel doit être aussi léger que possible.The use of the striking bell makes it possible to increase the section of the striking surface with which the base of the ram cooperates, without thereby excessively increasing the section of the body of the tool, which must be as light as possible.
Le bouchon 32, a sur toute sa hauteur, à l'exception de la partie appointée, une section telle qu'il se conforme par-faitement à celle du fourreau de la cheville, à quelques dixièmes de mm près, et une lubrification est recommandée pour faciliter le retrait de l'outil à la fin de l'opération d'enfoncement. La très faible épaisseur du jeu empêche la pénétration de la terre en cours d'enfoncement.The
La section réduite intermédiaire 31 réduit le risque d'adhérence du faux piquet au fourreau.The intermediate reduced
La pièce d'appui 5, la cloche 4 et même la portion centrale de guidage 21 et le bouchon 32 peuvent être montés de manière amovible (par vissage, ou emboîtage) de façon à être changés en cas d'usure ou de bris, ou encore, en ce qui concerne le bouchon et la portion centrale de guidage, en vue d'utiliser le même outil pour des chevilles ayant des fourreaux de sections différentes. A titre de variante, il est possible de donner à la partie centrale 2 la forme d'un tronc de cône dont la base supérieure aura un diamètre de 50 mm par exemple et la base inférieure, un diamètre de 35 mm. La section de cette partie centrale ne comportera alors aucune discontinuité et sa base inférieure se raccordera également sans discontinuité de section avec une partie supérieure tronconique de la broche 3. La pièce plate 5 ne comportera pas, dans cette variante, d'évidement central tel que 51 figure 1, mais sera directement emmanchée sur la partie centrale 2. ―The
Dans cette variante, plus simple à réaliser que celle de la figure 1, la partie centrale tronconique 2, en s'engageant au départ dans le fourreau de la cheville, viendra coincer celle-ci et, dès les premiers chocs du bélier, la cheville se trouvera évasée en remontant le long de la partie centrale tronconique 2, ce qui facilitera l'introduction du poteau en fin d'opération. Aucun risque de sertissage du fourreau de la cheville n'existe.In this variant, which is simpler to produce than that of FIG. 1, the frustoconical
Aux figures 2 et 3, on voit que le bélier comporte un manchon cylindrique 6 ayant par exemple 600 mm de long, un diamètre extérieur de 80 mm (égal à celui de la surface de frappe 42) et un diamètre intérieur de 31 mm (donc, légèrement supérieur à celui du manche 1 sur lequel il coulisse).In Figures 2 and 3, we see that the ram has a
La hauteur relativement grande et la section relativement faible du bélier donnent un meilleur guidage du coulissement avec une plus grande course, et un impact très centré sur la surface de frappe.The relatively large height and the relatively small section of the ram give better sliding guidance with a greater stroke, and a very centered impact on the striking surface.
Dans l'exemple décrit, on a prévu quatre poignées 7, 8, 9, 10 disposées avec une répartition uniforme à la périphérie du manchon 6 et solidarisées à celui-ci à une seule de leurs extrémités. En effet, on a constaté que la solidarisation de la poignée à ses deux extrémités entraînerait une rigidité telle que les ondes de chocs briseraient les jonctions au bout d'un certain temps de fonctionnement. De préférence, la solidarisation de la poignée se fait à sa partie inférieure, par une soudure longitudinale 71, qui offre une très grande résistance à l'arrachement par l'onde de choc qui prend naissance à proximité. La partie haute des poignées est laissée libre, ce qui permet la dissipation de l'onde de choc; pour éviter toutefois les vibrations parasites secondaires et les déformations, cette partie haute est incurvée à un niveau supérieur à celui de l'extrémité supérieure du manchon et son extrémité redescend pour pénétrer avec un très faible jeu dans un canal 72 ménagé dans le corps du manchon annulaire et débouchant à la surface extérieure transversale de celui-ci. Un intervalle 73 est ménagé entre la surface d'extrémité de la poignée et le fond du canal.In the example described, four
Il va de soi que, comme il a été dit dans le certificat d'addition susvisé, l'on pourrait, sans s'écarter de l'esprit de l'invention, tronquer le manche 1 du corps de l'outil et remplacer la partie supérieure de celui-ci et le bélier par le piston d'un vérin hydraulique, ou par tout autre dispositif d'enfoncement mécanique, les avantages propres à la réalisation des parties centrale et inférieure du corps 1 selon l'invention étant conservés.It goes without saying that, as was said in the abovementioned certificate of addition, one could, without departing from the spirit of the invention, truncate the handle 1 of the body of the tool and replace the upper part of the latter and the ram by the piston of a hydraulic cylinder, or by any other mechanical driving device, the advantages specific to the production of the central and lower parts of the body 1 according to the invention being preserved.
L'outil de l'invention n'est pas exclusivement utilisable avec la cheville décrite dans le certificat d'addition et le brevet susvisés, bien qu'il ait été plus particulièrement conçu pour s'y adapter.The tool of the invention cannot be used exclusively with the dowel described in the above-mentioned certificate of addition and patent, although it has been more particularly designed to adapt to it.
