Description

L'invention concerne un outil à main électrique comme, par exemple, un appareil de perçage ou de perforation, du type marteau électrique, ou un appareil de fixation, du type appareil de scellement à piston propulsé par gaz, ainsi qu'une batterie d'alimentation pour l'outil à main électrique.The invention relates to an electric hand tool such as, for example, a drill or perforation apparatus, such as an electric hammer, or a fastening apparatus, such as a gas-powered piston sealing apparatus, and a battery pack. supply for the electric hand tool.

De tels appareils peuvent comporter une électronique de commande et de régulation, une bougie d'allumage, un ventilateur, un moteur électrique ou autres composants nécessitant une alimentation électrique. Etant à actionnement manuel et autonomes, ils comportent également une batterie d'alimentation.Such devices may include control electronics, spark plug, fan, electric motor or other components requiring power. Being manually operated and autonomous, they also include a battery pack.

Après avoir monté la batterie à l'extérieur de l'ensemble des autres éléments de l'appareil, comme par exemple dans le document US 6 376 942 , (le préambule de la revendication 1 est basé sur ce document), avec l'inconvénient, notamment, de les exposer à des chocs pouvant les endommager, on a proposé de les disposer dans un logement de réception intérieur à l'appareil, ménagé par exemple dans une jambe raccordée au corps central de l'appareil et s'étendant parallèlement à sa poignée de manoeuvre.After mounting the battery on the outside of all other elements of the device, as for example in the document US 6,376,942 (The preamble of claim 1 is based on this document), with the disadvantage, in particular, to expose them to shocks that may damage them, it has been proposed to arrange them in a housing for receiving inside the device, arranged for example in a leg connected to the central body of the device and extending parallel to its operating handle.

Par souci de sécurité, il a encore été proposé de fixer la batterie dans l'appareil au moyen d'un dispositif de verrouillage à double action, la batterie pouvant être d'abord verrouillée mécaniquement et électriquement puis, déconnectée électriquement du reste de l'appareil tout en y restant mécaniquement reliée pour éviter que, par inattention, l'opérateur ne la laisse tomber. Le document EP 1 205 282 enseigne un tel dispositif comprenant, sur l'appareil, une double détente d'actionnement de deux doigts de retenue agencés pour coopérer successivement avec un unique cran de retenue ménagé sur la batterie. Mais une telle disposition n'écarte pas le risque que l'opérateur n'actionne la double détente inopinément deux fois et dégage ainsi totalement la batterie de l'appareil.For the sake of safety, it was further proposed to fix the battery in the device by means of a double-acting locking device, the battery can be first locked mechanically and electrically and then disconnected electrically from the rest of the device while remaining mechanically connected to prevent the operator from inadvertently dropping it. The document EP 1 205 282 teaches such a device comprising, on the apparatus, a double detent actuating two retaining fingers arranged to cooperate successively with a single retaining notch formed on the battery. But such an arrangement does not rule out the risk that the operator will actuate the double trigger unexpectedly twice and thus completely releases the battery of the device.

La présente invention vise à diminuer un tel risque.The present invention aims to reduce such a risk.

A cet effet, l'invention concerne tout d'abord un outil à main électrique ayant les caractéristiques décrites dans la revendication 1. Grâce à l'invention, pour totalement dégager la batterie de l'outil, un opérateur est obligé de la saisir par la main et de la sortir de son logement en vainquant les forces de frottement qui la retiennent, évitant ainsi tout risque d'une fausse manoeuvre non intentionnelle.To this end, the invention relates first of all to an electric hand tool having the characteristics described in claim 1. Thanks to the invention, to completely clear the battery of the tool, an operator is obliged to grasp it by the hand and take it out of its housing by defeating the friction forces that hold it, thus avoiding any risk of a false unintentional maneuver.

Des formes de réalisation préférées de l'outil sont décrites dans les revendications dépendantes 2 à 6.Preferred embodiments of the tool are described in dependent claims 2 to 6.

L'invention concerne aussi une batterie d'alimentation de composants à commande électrique pour l'outil à main électrique de l'invention, celle batterie ayant les caractéristiques décrites dans la revendication 7.The invention also relates to an electrically-controlled power supply battery for the electric hand tool of the invention, said battery having the features described in claim 7.

Des formes de réalisation préférées de la batterie sont décrites dans les revendications dépendantes 8 à 10.Preferred embodiments of the battery are described in dependent claims 8 to 10.

L'invention sera mieux comprise à l'aide de la description suivante des formes de réalisation préférées de l'outil et de la batterie de l'invention, en référence à la figure en annexe les représentant en coupe, mais non hachurée dans un souci de clarté.The invention will be better understood with the aid of the following description of the preferred embodiments of the tool and the battery of the invention, with reference to the appended figure showing them in section, but not hatched for the sake of clarity. clarity.

L'outil représenté sur la figure est ici un marteau perforateur destiné à frapper un foret, entraîné par ailleurs en rotation dans un matériau support, par l'intermédiaire d'un piston propulsé dans un cylindre, selon un axe 1, sous l'action d'un moteur électrique alimenté par une batterie 3 disposée dans un logement de réception 4 ménagé dans une jambe 5, s'étendant sensiblement orthogonalement à l'axe 1, raccordée au boîtier 2.The tool shown in the figure here is a hammer drill intended to hit a drill bit, furthermore rotated in a support material, by means of a piston propelled in a cylinder, along an axis 1, under the action an electric motor powered by a battery 3 arranged in a receiving housing 4 formed in a leg 5, extending substantially orthogonal to the axis 1, connected to the housing 2.

Egalement raccordée au boîtier, se trouve une poignée de manoeuvre coudée 6, avec une portion de jambe 7, sensiblement parallèle à la jambe de réception de la batterie 5 et une portion 8, de raccordement à la jambe de réception 5, s'étendant sensiblement parallèlement à l'axe 1.Also connected to the housing, is an angled operating handle 6, with a leg portion 7, substantially parallel to the receiving leg of the battery 5 and a portion 8, connecting to the receiving leg 5, extending substantially parallel to axis 1.

Dans la portion de raccordement de la poignée 8 est logée, dans un logement 13, une tige 9 de verrouillage mécanique et électrique s'étendant sensiblement parallèlement à l'axe 1. La tige 9 porte, dans son prolongement, du côté tourné vers le logement de batterie 4, un doigt de verrouillage 10.In the connecting portion of the handle 8 is housed, in a housing 13, a mechanical and electrical locking pin 9 extending substantially parallel to the axis 1. The rod 9 carries, in its extension, the side facing the battery compartment 4, a locking finger 10.

La tige de verrouillage 9 porte encore, latéralement, une détente d'actionnement 11 en saillie hors de la poignée 6 à travers une lumière 14, du côté intérieur 12 entre les deux portions 7, 8 et un doigt de rappel 15, s'étendant parallèlement à la tige 9, sur lequel est enfilé un ressort de rappel 16 prenant appui contre la paroi de fond 17 du logement 13 et contre un épaulement 18 ménagé par le doigt 15. Le doigt de verrouillage 10 est conformé pour présenter une rampe de passage 19 inclinée vers l'axe 1 de l'arrière 20 vers l'avant 21 de l'outil, pour le passage de la batterie 3 lors de son coulissement dans son logement 4.The locking rod 9 still carries, laterally, an actuating trigger 11 projecting from the handle 6 through a slot 14, the inner side 12 between the two portions 7, 8 and a return finger 15, extending parallel to the rod 9, on which is threaded a return spring 16 bearing against the bottom wall 17 of the housing 13 and against a shoulder 18 formed by the finger 15. The locking pin 10 is shaped to present a passage ramp 19 inclined towards the axis 1 of the rear 20 towards the front 21 of the tool, for the passage of the battery 3 during its sliding in its housing 4.

En position de repos, qui est la position de verrouillage, le doigt de verrouillage 10 est rappelé par le ressort 16 en saillie à l'intérieur du logement de batterie 4. La tige 9 est déplacée en position d'effacement du doigt 10 contre l'action du ressort 16. Dans la jambe de réception de batterie 5, du côté antérieur opposé à la poignée de manoeuvre 6 et donc à la tige et au doigt de verrouillage, et près du boîtier 2, est fixée, par une extrémité 23, une lame élastique 22, portant un bossage 24 à son extrémité libre formant doigt de retenue tourné vers le logement de réception de batterie 4. La lame 22 s'étend sensiblement orthogonalement à l'axe 1, mais sa portion libre est toutefois inclinée vers l'arrière pour pouvoir pivoter autour de son extrémité fixe 23 et pour que le doigt de retenue 24 puisse se déplacer sensiblement parallèlement à l'axe 1, entre une position de repos, qui est une position de verrouillage, dans laquelle il fait saillie à l'intérieur du logement de batterie 4, et une position d'effacement, dans son logement d'outil 38, contre l'élasticité de la lame.In the rest position, which is the locking position, the locking pin 10 is biased by the spring 16 projecting inside the battery housing 4. The rod 9 is moved to the erasing position of the finger 10 against the action of the spring 16. In the battery receiving leg 5, the anterior side opposite to the operating handle 6 and thus to the rod and the locking pin, and near the casing 2, is fixed, by one end 23, an elastic blade 22, carrying a boss 24 at its free end forming retaining finger turned towards the battery receiving housing 4. The blade 22 extends substantially orthogonal to the axis 1, but its free portion is however inclined towards the rearwardly to pivot about its fixed end 23 and that the retaining finger 24 can move substantially parallel to the axis 1, between a rest position, which is a locking position, in which it protrudes from the ' inside the battery housing 4, and an erase position, in its tool housing 38, against the elasticity of the blade.

En ce qui concerne la batterie 3, de forme générale sensiblement parallèlépipédique, près de sa face d'extrémité d'introduction 25, elle présente sur ses deux côtés latéraux opposés 26, 27 deux rampes de passage 28, 29 pour le franchissement respectivement du doigt de retenue mécanique 24 et du doigt de verrouillage mécanique et électrique 10. Un léger évidement, ou creux, 30 est ménagé légèrement au-delà de la rampe 28, présentant une rampe 31, inclinée en sens inverse de celui de la rampe 28, pour former d'une part, un bossage 32 de retenue mécanique de la batterie et, d'autre part, un logement 30 de réception du doigt de retenue 24 en position de repos. Le logement 30 est ici délimité, non seulement par la rampe 31, mais par une autre rampe 33 inclinée en sens inverse et située à une distance de la face d'introduction 25 au moins égale à la longueur de la lame 22 considérée dans la direction d'introduction de la batterie. Plus proche de sa face d'extrémité arrière 34, sur le côté 27, de la batterie, est ménagé un cran de verrouillage 35 comportant un épaulement interne en dépouille 36, tourné à l'opposé de la face d'introduction 25, et ici une rampe 37, inclinée comme la rampe de passage 19 du doigt de verrouillage 10.With regard to the battery 3, of substantially parallelepipedal general shape, near its introduction end face 25, it has on its two opposite lateral sides 26, 27 two passage ramps 28, 29 for the crossing respectively of the finger mechanical restraint 24 and the mechanical and electrical locking finger 10. A slight recess, or recess, 30 is formed slightly beyond the ramp 28, having a ramp 31, inclined in opposite direction to that of the ramp 28, for form firstly, a boss 32 for mechanical retention of the battery and, secondly, a housing 30 for receiving the retaining finger 24 in the rest position. The housing 30 is here delimited, not only by the ramp 31, but by another ramp 33 inclined in the opposite direction and located at a distance from the insertion face 25 at least equal to the length of the blade 22 considered in the direction introduction of the battery. Closer to its rear end face 34, on the side 27, of the battery is formed a locking notch 35 having an internal flange 36, turned away from the insertion face 25, and here a ramp 37, inclined as the passage ramp 19 of the locking pin 10.

Le montage et démontage de la batterie 3 dans l'outil vont maintenant être expliqués.The assembly and disassembly of the battery 3 in the tool will now be explained.

Présentant la batterie 3 par sa face d'introduction 25, on l'introduit dans le logement 4. On l'y pousse dans le sens de la flèche 39, sensiblement orthogonale à l'axe 1. La rampe 29, en coopérant avec la rampe 19 du doigt de verrouillage 10, l'escamote dans son logement 13, contre l'action du ressort 16. On continue de pousser la batterie, le doigt de verrouillage 10 glissant sur le côté 27 de la batterie, jusqu'à ce que la rampe 28, en coopérant avec le doigt de retenue 24, l'escamote à son tour dans son logement d'outil 38 contre l'élasticité de la lame 22, puis que le doigt de retenue 24, après passage du bossage 32, et par détente élastique de la lame 22, ne se replace dans le logement de batterie 30.Presenting the battery 3 by its introduction face 25, it is introduced into the housing 4. It is pushed in the direction of the arrow 39, substantially orthogonal to the axis 1. The ramp 29, cooperating with the ramp 19 of the locking finger 10, the retractor in its housing 13, against the action of the spring 16. It continues to push the battery, the locking finger 10 sliding on the side 27 of the battery, until the ramp 28, cooperating with the retaining finger 24, the escamote in turn in its tool housing 38 against the elasticity of the blade 22, then the retaining finger 24, after passage of the boss 32, and by elastic expansion of the blade 22, does not replace the battery housing 30.

Dans cette position, la batterie n'est pas encore électriquement connectée, mais elle est mécaniquement retenue dans l'outil, en ce sens que, pour l'en extraire, il faudrait tirer sur elle pour vaincre la force de frottement nécessaire au passage du bossage 32 au-delà du doigt de retenue 24.In this position, the battery is not yet electrically connected, but it is mechanically retained in the tool, in that, in order to extract it, it would be necessary to fire on it to overcome the friction force necessary for the passage of the boss 32 beyond the retaining finger 24.

On notera que du fait de la hauteur ou de l'étendue du logement de batterie 30, un certain débattement de la batterie reste possible, sans pour autant que la connexion électrique ne se produise de façon inopinée.Note that due to the height or extent of the battery housing 30, a certain travel of the battery is possible, without the electrical connection does not occur unexpectedly.

En continuant de pousser la batterie 3 dans son logement 4, on parvient à son véritable encliquetage, c'est-à-dire son verrouillage mécanique et électrique, quand le cran de retenue 35 se présente en face du doigt de retenue 10, qui, sous l'action du ressort 16, est rappelé en coulissement dans le cran.Continuing to push the battery 3 into its housing 4, one achieves its true latching, that is to say its mechanical and electrical locking, when the retaining notch 35 is in front of the retaining finger 10, which under the action of the spring 16, is recalled in sliding in the notch.

Inversement, pour retirer la batterie 3 de son logement 4, on actionne la détente 11, contre l'action du ressort 16 pour dégager le doigt 10 du cran 35 puis on tire la batterie pour la déconnecter électriquement des composants électriques de l'outil. Elle reste toutefois mécaniquement solidaire de l'outil, tant qu'on n'a pas fait passer le bossage 32 au-delà du doigt de retenue 24. Ce n'est qu'en forçant pour faire passer ce bossage au-delà du doigt 24 et vaincre les forces de frottement correspondantes qu'on peut totalement dégager la batterie de l'outil.Conversely, to remove the battery 3 from its housing 4, the trigger 11 is actuated, against the action of the spring 16 to release the finger 10 of the notch 35 and then pulls the battery to disconnect electrically electrical components of the tool. However, it remains mechanically secured to the tool, as long as it has not passed the boss 32 beyond the retaining finger 24. This is only forcing to pass this boss beyond the finger 24 and overcome the corresponding friction forces that can completely clear the battery of the tool.
