Description

L'invention concerne un dispositif de portage pour un outil à main électrique.The invention relates to a carrying device for an electric hand tool.

Les outils à main électriques comprennent soit une source d'énergie électrique logée à l'intérieur de l'outil sous la forme de piles ou de batteries rechargeables, soit un câble électrique pour raccorder l'outil à une prise d'un réseau d'électricité ou d'un générateur d'électricité ou encore, les outils à main électriques comprennent deux modules, dont l'un est une machine électrique formant l'outil proprement dit et l'autre une source d'énergie électrique. Dans ce dernier cas, les deux modules sont reliés entre eux, de manière permanente ou non, par un câble électrique et le module formant la source d'énergie électrique assure souvent aussi la fonction de module de commande de la machine. La présente invention s'applique aux outils à main électriques selon la troisième conception.Electric hand tools comprise either a source of electrical energy housed inside the tool in the form of rechargeable batteries or rechargeable batteries, or an electric cable for connecting the tool to a socket of a power supply network. electricity or an electricity generator or the electric hand tools comprise two modules, one of which is an electrical machine forming the tool itself and the other a source of electrical energy. In the latter case, the two modules are interconnected, permanently or not, by an electric cable and the module forming the source of electrical energy often also performs the function of control module of the machine. The present invention applies to electric hand tools according to the third design.

Les outils à main électriques tels que des cisailles électriques pour des travaux de coupe dans les domaines agricole, viticole ou jardinerie doivent développer une force de coupe assez importante et ont ainsi besoin d'une source d'électricité assez puissante et, en conséquence, assez lourde.Electric hand tools such as electric shears for cutting work in the agricultural, viticultural or gardening fields must develop a fairly large cutting force and thus require a fairly powerful source of electricity and, as a result, enough heavy.

Par ailleurs, certains outils à main doivent être alimentés non seulement en énergie électrique, mais également en une matière consommable, qu'il s'agisse d'une matière solide, liquide, gazeuse ou mixte, cette matière étant appelée par la suite un fluide consommable. Ce fluide consommable est déterminé selon le travail spécifique à effectuer avec l'outil à main électrique et est alors débité par l'outil, par exemple, en alternance avec des gestes de travail ou simultanément avec ceux-ci. Un autre exemple est le débit d'un fluide consommable accompagnant les gestes de l'outil, tel la dispersion d'un liquide de traitement de plantes pendant la coupe de celles-ci ou le débit d'un matériau filaire pour attacher des brins d'une série de plantes à un fil de soutien ou à une barre de soutien.Moreover, certain hand tools must be supplied not only with electrical energy, but also with a consumable material, be it a solid, liquid, gaseous or mixed material, this material being called thereafter a fluid consumable. This consumable fluid is determined according to the specific work to be performed with the electric hand tool and is then debited by the tool, for example, alternately with working gestures or simultaneously with them. Another example is the flow of a consumable fluid accompanying the gestures of the tool, such as the dispersion of a plant treatment liquid during the cutting thereof or the flow of a wire material to attach strands of a series of plants to a support wire or a support bar.

Pour tous ces travaux, l'outil à main doit comprendre un logement de stockage pour le fluide consommable. Ce logement peut être situé sur l'outil proprement dit ou être réuni avec, ou intégré dans, le module fournissant l'énergie électrique et éventuellement des signaux de commande pour la machine électrique formant l'outil proprement dit. Dans cette seconde situation, l'outil comprend des moyens assurant le transport du fluide consommable entre les deux modules.For all these works, the hand tool must include a storage housing for the consumable fluid. This housing may be located on the tool itself or be brought together with, or integrated into, the module supplying electrical energy and possibly control signals for the electrical machine forming the tool itself. In this second situation, the tool comprises means for transporting the consumable fluid between the two modules.

Indépendamment du type spécifique de l'outil, de tels outils à main électriques sont destinés à des travaux qui impliquent que l'opérateur ou l'utilisateur de l'outil se déplace pendant son travail sur des distances assez importantes et, de plus, effectue pendant la durée éntière du travail avec le corps entier des mouvements assez importants et irréguliers.Regardless of the specific type of tool, such electric hand tools are intended for work that implies that the operator or user of the tool travels during his work over quite large distances and, in addition, performs during the whole duration of the work with the whole body of the rather important and irregular movements.

Il est aisé de s'imaginer qu'un tel travail, par exemple couper ou attacher des brins ou des branches de plantes ou de buissons, notamment lorsqu'il est à effectuer à une hauteur réduite, parfois proche du sol, est déjà en soi un travail pénible de par la position inconfortable de l'opérateur de l'outil. A cela s'ajoute alors la gêne généralement produite par le fait que l'opérateur doit porter, par exemple en bandoulière sur l'épaule, le module assurant l'alimentation électrique de l'outil à main et assurant éventuellement aussi la commande de celui-ci.It is easy to imagine that such work, for example cutting or tying strands or branches of plants or bushes, especially when it is to be performed at a reduced height, sometimes close to the ground, is already in itself a painful job due to the uncomfortable position of the operator of the tool. To this is added the inconvenience generally caused by the fact that the operator must wear, for example shoulder over the shoulder, the module ensuring the power supply of the hand tool and possibly also ensuring the control of the -this.

Le but de l'invention est de proposer un moyen permettant à un utilisateur ou opérateur d'un outil à main électrique comportant un module séparé assurant au moins l'alimentation électrique de l'outil, de porter le module aisément et sans atteinte sur la mobilité de l'utilisateur ou opérateur.The object of the invention is to provide a means for a user or operator of an electric hand tool having a separate module providing at least the power supply of the tool, to carry the module easily and without interference on the mobility of the user or operator.

Le but de l'invention est atteint avec un dispositif de portage pour un outil à main à énergie électrique, utilisant éventuellement un fluide consommable et comportant un module séparé assurant au moins l'alimentation en énergie électrique de l'outil.The object of the invention is achieved with a carrying device for an energy hand tool electrical, possibly using a consumable fluid and having a separate module providing at least the electrical power supply of the tool.

Le dispositif de portage de l'invention est conçu de manière à permettre d'une part à l'opérateur de l'outil à main électrique de porter le module d'alimentation en énergie électrique, éventuellement aussi en fluide consommable, et de commande sur le dos et cela de manière que le module ne bouge pas et que le dispositif de portage ne gêne pas non plus les mouvements de l'opérateur de l'outil. Par ailleurs, le dispositif de portage est conçu de manière à être adaptable à des personnes de différentes tailles et de différentes corpulences.The carrying device of the invention is designed so as on the one hand to allow the operator of the electric hand tool to carry the power supply module with electrical energy, possibly also with consumable fluid, and control on the back and that so that the module does not move and the carrying device does not interfere with the movements of the operator of the tool. Furthermore, the carrying device is designed to be adaptable to people of different sizes and different body sizes.

  • la figure 1 montre le dispositif de portage selon un mode de réalisation préféré de l'invention en une vue arrière,
  • la figure 2 montre le dispositif de la figure 1 en une vue avant,
  • la figure 3 montre le dispositif de l'invention en une variante de réalisation,
  • la figure 4 montre le dispositif de l'invention en position d'utilisation du côté de la fixation ventrale, et
  • la figure 5 montre le dispositif de l'invention en position d'utilisation du côté du dos de l'opérateur.
Other features and advantages of the present invention will emerge from the following description of a preferred embodiment of the invention and an alternative embodiment. This description is made with reference to the drawings in which:
  • FIG. 1 shows the carrying device according to a preferred embodiment of the invention in a rear view,
  • FIG. 2 shows the device of FIG. 1 in a front view,
  • FIG. 3 shows the device of the invention in an alternative embodiment,
  • FIG. 4 shows the device of the invention in the position of use on the side of the ventral fixation, and
  • Figure 5 shows the device of the invention in use position on the back side of the operator.

La figure 1 représente le dispositif de portage de l'invention en une vue arrière, c'est-à-dire du côté qui se présente à un observateur lorsque ce dernier regarde un opérateur ayant mis le dispositif de portage sur son dos, et la figure 2 montre le dispositif de portage du côté destiné à venir en contact avec le dos de l'opérateur lorsque ce dernier le porte à la façon d'un sac à dos.FIG. 1 represents the carrying device of the invention in a rear view, that is to say on the side that presents itself to an observer when the latter is looking at an operator having put the carrying device on his back, and the Figure 2 shows the carrying device on the side intended to come into contact with the back of the operator when the latter wears it in the manner of a backpack.

Le dispositif de portage de l'invention est donc destiné à un outil à main à énergie électrique, utilisant éventuellement un fluide consommable et comportant une machine électrique formant l'outil proprement dit et un module séparé. Le module séparé, qu'un opérateur peut porter sur le dos grâce au dispositif de portage de l'invention, assure au moins l'alimentation en énergie électrique de l'outil, mais assure le cas échéant aussi l'alimentation en un fluide consommable spécifique pour le travail à effectuer et émet éventuellement des signaux de commande à la machine électrique.The carrying device of the invention is therefore intended for an electric power hand tool, possibly using a consumable fluid and comprising an electric machine forming the actual tool and a separate module. The separate module, which an operator can wear on the back thanks to the carrying device of the invention, ensures at least the supply of electrical energy to the tool, but if necessary also provides the supply of a consumable fluid specific for the work to be performed and possibly transmit control signals to the electric machine.

Le dispositif de portage comprend une partie dorsale 1 moulée ou postformée qui est munie de deux bretelles 2 matelassés et progressivement réglable en longueur, d'une anse 3 pour porter le dispositif à la main et d'un compartiment 10 destiné à recevoir le module. Cette partie dorsale 1 permet à un opérateur de l'outil d'immobiliser le module sur le dos de manière que le module ne puisse bouger et, ainsi, ne puisse gêner l'opérateur pendant ses mouvements. La machine électrique est reliée électriquement au module par un câble électrique. L'outil comprend par ailleurs, le cas échéant, un conduit flexible ou tout autre moyen approprié pour l'alimentation en fluide consommable.The carrying device comprises a dorsal portion 1 molded or postformed which is provided with two padded straps 2 and progressively adjustable in length, a handle 3 to carry the device by hand and a compartment 10 for receiving the module. This back part 1 allows an operator to the tool to immobilize the module on the back so that the module can not move and, thus, can not hinder the operator during his movements. The electrical machine is electrically connected to the module by an electric cable. The tool also comprises, where appropriate, a flexible conduit or any other suitable means for the supply of consumable fluid.

Pour obtenir une position fixe du module sur l'opérateur, la partie dorsale 1 est pourvue d'une bande d'attache ventrale 4 sensiblement inextensible et de deux bandes d'attache ventrales 5, 6 élastiquement extensibles. La bande d'attache ventrale sensiblement inextensible 4 et les deux bandes d'attache ventrales élastiquement extensibles 5, 6 formant ensemble une ceinture élastique conformée pour pouvoir être fermée à des longueurs progressivement variables.To obtain a fixed position of the module on the operator, the dorsal portion 1 is provided with a band of ventral attachment 4 substantially inextensible and two elastically expandable belly fastening strips 5, 6. The substantially inextensible ventral attachment band 4 and the two elastically extensible ventral attachment strips 5, 6 together form a resilient waistband shaped to be closable to progressively varying lengths.

Cette disposition rend possible que le dispositif de portage puisse être utilisé par des personnes de différentes corpulences. Pour obtenir la fermeture progressivement variable, la bande d'attache ventrale sensiblement inextensible 4 comprend une partie 7 d'une fermeture à crochets et boucles et les deux bandes d'attache ventrale élastiquement extensibles 5, 6 comportent l'autre partie 8 de la fermeture à crochets et boucles.This arrangement makes it possible for the carrying device to be used by people of different body types. To obtain the progressively variable closing, the substantially inextensible ventral fastening band 4 comprises a portion 7 of a hook and loop fastener and the two elastically extensible ventral fastening strips 5, 6 comprise the other part 8 of the closure with hooks and loops.

Avantageusement, la bande d'attache ventrale sensiblement inextensible 4 comporte des boucles miniatures 7 d'une fermeture à crochets et boucles et les deux bandes d'attache ventrale élastiquement extensible 5, 6 comportent des crochets 8 de la fermeture à crochets et boucles.Advantageously, the substantially inextensible ventral fastening band 4 comprises miniature loops 7 of a hook and loop fastener and the two elastically extensible ventral fastening strips 5, 6 comprise hooks 8 of the hook and loop closure.

Pour assurer à la fois une fermeture sûre de la ceinture élastique et un certain confort ou agrément par absence de contraintes nuisibles du dispositif de portage, la bande d'attache ventrale sensiblement inextensible 4 est fixée, par exemple cousue, par une extrémité 41 sur un bord latéral 121 de la partie dorsale 1 et les deux bandes d'attache ventrale élastiquement extensibles 5, 6 sont fixées, de manière analogue, par leurs extrémités 51, 61 sur le bord latéral opposé 122 de la partie dorsale 1. La bande d'attache ventrale 4 est recouverte jusqu'à son extrémité libre 42 sur le côté destiné à être orienté vers l'extérieur lorsque le dispositif de l'invention est en position d'utilisation, des boucles miniatures 7 de la fermeture à crochets et boucles 7, 8.To ensure both a secure closure of the elastic belt and a certain comfort or amenity by absence of harmful constraints of the carrying device, the substantially inextensible ventral fastening band 4 is fixed, for example sewn, by an end 41 on a side edge 121 of the back portion 1 and the two elastically extensible waistbands 5, 6 are similarly fixed by their ends 51, 61 on the opposite lateral edge 122 of the dorsal portion 1. The ventral attachment band 4 is covered until at its free end 42 on the side intended to be oriented outwards when the device of the invention is in the position of use, miniature loops 7 of the hook and loop closure 7, 8.

Contrairement à cela, les deux bandes d'attache ventrale élastiquement extensibles 5, 6 sont pourvues, sur la face respective destinée à être orientée vers l'intérieur, c'est-à-dire vers le ventre de l'opérateur du dispositif, et de préférence uniquement sur une partie proche des extrémités libres 52, 62, avec des crochets 8 de la fermeture à crochets et boucles 7, 8.In contrast to this, the two elastically extensible belly fastening strips 5, 6 are provided, on the respective face intended to be oriented towards the inside, that is to say toward the belly of the operator of the device, and preferably only on a portion near the free ends 52, 62, with hooks 8 of the hook and loop closure 7, 8.

Selon les dispositions de l'invention, les deux bandes d'attache ventrale élastiquement extensibles 5, 6 ont des longueurs différentes. Ainsi, les deux bandes 5, 6 sont fixées sur la partie dorsale 1 et orientées de manière que l'extrémité libre 62 de la bande d'attache centrale plus longue 6 recouvre au moins partiellement l'extrémité libre 52 de la bande d'attache ventrale moins longue 5 lorsque le dispositif de l'invention est en position d'utilisation et fermé sur le ventre d'un opérateur.According to the provisions of the invention, the two elastically extensible belly fastening strips 5, 6 have different lengths. Thus, the two strips 5, 6 are fixed on the dorsal part 1 and oriented so that the free end 62 of the longer central fastening strip 6 at least partially covers the free end 52 of the fastening strip. Ventrale less long 5 when the device of the invention is in the use position and closed on the belly of an operator.

La figure 3 montre une variante de réalisation du dispositif de portage de l'invention. Cette variante se distingue du mode de réalisation préféré de l'invention par le fait qu'elle ne comporte qu'une seule bande d'attache ventrale élastiquement extensible, référencée ici 5A.Figure 3 shows an alternative embodiment of the carrying device of the invention. This variant differs from the preferred embodiment of the invention in that it comprises only one elastically extensible belly strap, referenced here 5A.

Aussi bien le mode de réalisation préféré de l'invention que sa variante permettent de porter le module de l'outil à main électrique confortablement et sans contrainte pour le mouvement de l'opérateur. Cependant, le mode de réalisation préféré avec deux bandes d'attache ventrale élastiques apporte un plus grand confort du fait d'une couverture plus large de la partie ventrale de l'opérateur. De plus, le chevauchement au moins partiel des deux bandes d'attache ventrale élastique 5, 6 apporte, outre l'avantage d'une fixation plus sure, une décharge de contrainte pour la bande plus courte, ce qui contribue dans l'ensemble à un serrage moindre du ventre de l'opérateur.Both the preferred embodiment of the invention and its variant can carry the module of the electric hand tool comfortably and without constraint for the movement of the operator. However, the preferred embodiment with two Elastic chest strap provides greater comfort due to a wider coverage of the ventral part of the operator. In addition, the at least partial overlap of the two elastic ventral attachment bands 5, 6 provides, in addition to the advantage of a more secure fixation, a strain relief for the shorter band, which contributes overall to less tightness of the operator's belly.

Comme les figures 2 et 3 le montrent, la partie dorsale 1 comporte avantageusement, mais pas nécessairement, des lignes de pliage 13, 14, 15 préformées. La ligne de pliage 13 est une ligne de pliage transversale divisant la partie dorsale 1 en une partie supérieure 11 et une partie inférieure 12. Le compartiment 10 destiné à recevoir le module séparé assurant au moins l'alimentation électrique de l'outil est fixé sur la partie inférieure 12 de la partie dorsale 1 et se trouve ainsi au croisement des lignes de fixation du dispositif de portage sur l'opérateur, ces lignes étant formées par les bretelles 2 d'une part et par la ceinture élastique 4, 5 d'autre part.As Figures 2 and 3 show, the dorsal portion 1 advantageously, but not necessarily, fold lines 13, 14, 15 preformed. The fold line 13 is a transverse fold line dividing the dorsal portion 1 into an upper portion 11 and a lower portion 12. The compartment 10 for receiving the separate module providing at least the power supply of the tool is fixed on the lower part 12 of the dorsal part 1 and is thus at the intersection of the attachment lines of the carrying device on the operator, these lines being formed by the straps 2 on the one hand and by the elastic belt 4, 5 of somewhere else.

Les lignes de pliage 14, 15 sont des lignes disposées approximativement verticalement, par rapport à la position d'utilisation du dispositif de portage. Elles sont préformées sur la partie inférieure 12 de la partie dorsale 1 approximativement parallèlement aux bords latéraux 121, 122 correspondants de la partie inférieure 12. Bien que la disposition de deux lignes de pliage respectivement à droite et à gauche du compartiment 10 se soit avérée comme avantageuse, il est toutefois possible, sans sortir du principe de la présente invention, de ne prévoir qu'une seule ligne de pliage 14 de chaque côté du compartiment 10. La présence de ces deux ou quatre lignes de pliage (voire même six lignes de pliage) permet à la partie inférieure 12 de la partie dorsale 1 d'épouser le mieux possible le corps de l'opérateur de l'outil et contribue ainsi de manière non négligeable à une bonne fixation et immobilisation du module séparé sur le dos de l'opérateur.The fold lines 14, 15 are lines arranged approximately vertically, with respect to the position of use of the carrying device. They are preformed on the lower part 12 of the dorsal part 1 approximately parallel to the corresponding lateral edges 121, 122 of the lower part 12. Although the arrangement of two fold lines respectively to the right and to the left of the compartment 10 has proved to be However, without departing from the principle of the present invention, it is possible to provide only one fold line 14 on each side of the compartment 10. The presence of these two or four fold lines (or even six lines of folding) allows the lower part 12 of the dorsal part 1 to marry as well as possible the body of the operator of the tool and thus contributes significantly to a good fixing and immobilization of the separate module on the back of the operator.

La figure 5 montre le dispositif de l'invention en position d'utilisation du côté du dos de l'opérateur. Il est aisé d'apprécier, sans que l'on ait besoin d'en faire l'objet d'une figure supplémentaire, que la présence d'une ligne de pliage transversale, référencée 13 sur les figures 2 et 3, contribue à l'obtention d'une bonne assise de la partie dorsale 1 du dispositif de portage sur le dos de l'opérateur. En même temps, la flexibilité relative de la partie dorsale 1, qui résulte de la présence de la ligne de pliage 13, comme d'ailleurs aussi de la présence des lignes de pliage 14 et, le cas échéant, 15, contribue de manière non négligeable au confort dont l'opérateur bénéficie grâce aux dispositions de l'invention.Figure 5 shows the device of the invention in use position on the back side of the operator. It is easy to appreciate, without the need for an additional figure, that the presence of a transverse fold line, referenced 13 in FIGS. obtaining a good base of the dorsal portion 1 of the carrying device on the back of the operator. At the same time, the relative flexibility of the dorsal part 1, which results from the presence of the fold line 13, as also from the presence of the fold lines 14 and, where appropriate, 15, contributes in a non-linear manner. negligible comfort that the operator benefits from the provisions of the invention.

Par ailleurs, la présence d'une ligne de pliage transversale 13 permet de replier la partie supérieure 11 de la partie dorsale 1 sur la partie inférieure 12, et de donner ainsi au dispositif des dimensions de rangement moindres, ce qui est particulièrement utile lorsqu'il s'agit de ranger le dispositif dans une armoire en attente d'une prochaine utilisation du dispositif.Furthermore, the presence of a transverse fold line 13 makes it possible to fold the upper part 11 of the dorsal part 1 onto the lower part 12, and thus to give the device smaller storage dimensions, which is particularly useful when it is to store the device in a cabinet waiting for a next use of the device.

Le dispositif de portage de l'invention comporte avantageusement, mais non nécessairement, une ceinture supplémentaire 9 permettant de fixer sur le dispositif de l'invention un étui pour l'outil proprement dit, comme le montre plus particulièrement la figure 4.The carrying device of the invention advantageously comprises, but not necessarily, an additional belt 9 for fixing on the device of the invention a case for the tool itself, as shown more particularly in FIG. 4.
