Description
La présente invention concerne un dispositif d'aide pour la préhension et l'enfoncement d'un clou.The present invention relates to a support device for gripping and driving a nail.
Pour planter un clou, la méthode la plus couramment utilisée est de saisir le clou avec les doigts, de placer la pointe du clou à l'endroit où celui-ci doit être enfoncé en disposant le clou sensiblement perpendiculairement à la surface dans laquelle le clou doit prendre place puis de frapper la tête du clou avec un marteau. Lors de cette dernière opération, il arrive que le marteau dérape et vienne frapper les doigts du bricoleur. Ceci est douloureux et l'hématome qui en résulte est souvent long à disparaître.To plant a nail, the most commonly used method is to grasp the nail with the fingers, to place the tip of the nail where it should be driven by placing the nail substantially perpendicular to the surface in which the nail must take place and then hit the head of the nail with a hammer. During this last operation, it happens that the hammer skids and comes to hit the fingers of the handyman. This is painful and the resulting hematoma is often slow to disappear.
Des dispositifs permettant la préhension de clous à l'aide d'un aimant existent déjà. On peut citer par exemple le document
Ces divers dispositifs ont entre autres comme inconvénient de nécessiter l'usage de deux mains pour actionner la virole et orienter la pointe à planter.These various devices have the disadvantage of requiring the use of two hands to actuate the shell and orient the tip to be planted.
La présente invention a alors pour but de fournir un dispositif aidant un bricoleur qui souhaite planter un clou. Avantageusement, le dispositif selon l'invention permet de faciliter également la préhension du clou.The present invention therefore aims to provide a device helping a handyman who wants to plant a nail. Advantageously, the device according to the invention also makes it easier to grip the nail.
A cet effet, elle propose un dispositif de préhension destiné notamment à la préhension de clous, comportant un manche, un aimant et une virole fixe par rapport au manche.For this purpose, it proposes a gripping device intended in particular for grasping nails, comprising a handle, a magnet and a ferrule fixed relative to the handle.
Selon l'invention, le manche porte à l'une de ses extrémités un ensemble comportant la virole, l'aimant ainsi qu'une protection, la virole est de forme tubulaire, la protection vient obturer, au moins partiellement, une extrémité de la virole et est au contact de l'aimant, et l'autre extrémité du manche est munie d'une partie à frapper.According to the invention, the handle carries at one of its ends an assembly comprising the ferrule, the magnet and a protection, the ferrule is of tubular shape, the protection closes, at least partially, one end of the ferrule and is in contact with the magnet, and the other end of the handle is provided with a striking part.
Dans une forme de réalisation préférentielle, le manche est réalisé dans un matériau isolant. Ainsi il n'y a pas de risque d'électrocution si le clou enfoncé perce un câble électrique.In a preferred embodiment, the handle is made of an insulating material. Thus there is no risk of electrocution if the recessed nail pierces an electric cable.
La protection du dispositif de préhension est par exemple prise en sandwich entre la virole et l'aimant.The protection of the gripping device is for example sandwiched between the ferrule and the magnet.
Une variante de réalisation prévoit qu'une vis traverse le manche et relie la partie à frapper à la protection.An alternative embodiment provides that a screw passes through the handle and connects the striking part to the protection.
Pour pouvoir s'adapter à différentes tailles de clous, la virole est avantageusement montée par vissage et est interchangeable.To adapt to different sizes of nails, the ferrule is advantageously mounted by screwing and is interchangeable.
Dans une variante de réalisation d'un dispositif de préhension selon l'invention, la protection est munie d'une saillie présentant la forme d'un embout de tournevis. Le dispositif peut alors être utilisé pour le vissage d'une vis. Dans cette variante de réalisation la protection munie d'une saillie est avantageusement interchangeable.In an alternative embodiment of a gripping device according to the invention, the protection is provided with a projection having the shape of a screwdriver bit. The device can then be used for screwing a screw. In this variant embodiment the protector provided with a projection is advantageously interchangeable.

Le dispositif représenté sur la
Le manche tubulaire 2 est de préférence réalisé dans un matériau isolant. Il est par exemple réalisé dans une matière synthétique rigide ou une résine. On peut également envisager un manche tubulaire en bois. Ce manche tubulaire 2 est par exemple de forme cylindrique circulaire. Son diamètre extérieur est adapté pour pouvoir être aisément saisi d'une main. Sa surface extérieure peut présenter une forme ergonomique facilitant sa préhension.The
L'aimant 4 se présente sous la forme d'un disque dont le diamètre correspond au diamètre extérieur du manche tubulaire 2. Cet aimant 4 est disposé à une extrémité du manche tubulaire 2 en fermant cette extrémité.The magnet 4 is in the form of a disk whose diameter corresponds to the outer diameter of the
La protection 6 se présente dans la forme de réalisation de la
La virole 8 est quant à elle réalisée dans un matériau non magnétique. Elle présente une forme tubulaire cylindrique de section circulaire. Son diamètre extérieur est inférieur au diamètre extérieur du manche tubulaire 2. Son diamètre intérieur détermine la taille de la tête des clous pouvant être plantés à l'aide du présent dispositif. Cette virole 8 est par exemple fixée sur la protection 6 par brasage. Cette virole 8 est montée de préférence coaxialement avec le manche tubulaire 2.The
La partie à frapper 10 est disposée à l'extrémité du manche tubulaire 2 opposée à l'extrémité recevant l'aimant 4. Cette partie à frapper 10 vient fermer le manche tubulaire 2 et est par exemple réalisée en bronze. Dans la forme de réalisation représentée au dessin, cette partie à frapper 10 présente une forme tronconique, la partie de plus petit diamètre du tronc de cône correspondant sensiblement au diamètre extérieur du manche tubulaire 2.The
L'ensemble des éléments décrits ci-dessus est assemblé à l'aide d'une vis 12 utilisée pour maintenir toutes ces pièces assemblées. Cette vis 12 est légèrement plus longue que le manche tubulaire 2. Cette vis 12 traverse la protection 6, l'aimant 4 et vient se viser dans la partie à frapper 10. De préférence, cette vis 12 est centrée sur l'axe du manche tubulaire 2. Un taraudage correspondant est prévu dans la partie à frapper 10. De même, un alésage est prévu dans l'aimant 4 et dans sa protection 6. Avantageusement, la tête de la vis 12 est une tête plate et celle-ci est noyée dans la protection 6.All of the elements described above is assembled using a
La
La virole 28 se présente ici aussi sous la forme d'une pièce tubulaire cylindrique de section circulaire et est réalisée dans un matériau non magnétique, par exemple en laiton.The
La protection 26 se présente ici sous la forme d'une pastille venant fermer une extrémité de la virole 28. Le diamètre de cette pastille correspond sensiblement au diamètre extérieur de la virole 28. La protection 26 est par exemple réalisée en nickel.The
L'aimant 24 est disposé au-dessus de la protection 26 de telle sorte que cette protection 26 se trouve en sandwich entre l'aimant 24 et la virole 28.The
Les protections 6 et 26 sont destinées à protéger les aimants 4 et 24 car les matériaux utilisés pour réaliser des aimants résistent mal aux chocs. Ces protections encaissent alors les coups reçus à la place des aimants 4, 24.The
Le manche 20 est ici un manche réalisé en résine et est obtenu par moulage par injection. L'ensemble décrit précédemment et formé par la virole 28, la protection 26 et l'aimant 24 est alors placé dans un moule et est surmoulé par la résine constituant le manche 22. L'extrémité de la virole 28, opposée à la protection 26 et à l'aimant 24, reste ouverte. La forme du manche 22 représentée est donnée à titre d'exemple. Le manche 22 représenté comporte une forme tronconique du côté de la virole 28 se raccordant à une forme cylindrique circulaire. Ici aussi, le manche 22 est destiné à être saisi par la main d'un utilisateur et sa surface extérieure peut être par exemple cylindrique circulaire ou présenter toute autre forme, ergonomique et/ou esthétique.The handle 20 is here a handle made of resin and is obtained by injection molding. The assembly described above and formed by the
Du côté opposé à la virole 28, le manche 22 reçoit la partie à frapper 30. Cette partie à frapper 30 est par exemple ici aussi réalisée en bronze. Elle peut se présenter sous la forme d'une pastille venant recouvrir le manche 22 en résine. Le manche 22 est par exemple muni d'un taraudage et la partie à frapper 30 d'une tige filetée correspondante (comme représenté sur la
La
Dans cette troisième forme de réalisation la virole 38 est interchangeable. On peut alors monter sur le dispositif de préhension des viroles dont la partie creuse présente des diamètres différents. De cette manière, l'outil de préhension s'adapte à des clous de différentes tailles.In this third embodiment the
Le fonctionnement de ces trois dispositifs est similaire. Pour saisir un clou, on vient approcher l'extrémité ouverte de la virole 8, 28, 38 de la tête 14 d'un clou 16. Cette tête 14 est alors attirée par l'aimant 4, 24, 34 et est guidée à l'intérieur de la virole jusqu'à ce que la tête 14 vienne au contact de la protection 6, 26, 36. Le clou tient alors grâce à la seule force d'attraction de l'aimant contre la protection. La pointe du clou 16 peut alors être positionnée à l'endroit où le clou doit être planté. Une fois la pointe en place, on vient frapper à l'aide d'un marteau la partie à frapper 10, 30, 40. Dans la première forme de réalisation, l'effort exercé sur la partie à frapper est transmis au clou directement par l'intermédiaire de la vis 12. On a ainsi une excellente transmission de la frappe du marteau vers le clou 16. Dans les deux autres formes de réalisation, c'est le manche 22, 32 tout entier qui retransmet la frappe du marteau vers le clou 16.The operation of these three devices is similar. To grasp a nail, the open end of the
Après le premier coup de marteau, ou un coup suivant, le clou 16 est partiellement enfoncé. Il est alors possible de retirer le dispositif selon l'invention et de venir frapper directement la tête 14 du clou 16. Il est alors inutile, le clou étant déjà partiellement planté, de venir tenir le clou avec les doigts. Il n'y a donc aucun risque de blessure.After the first hammer blow, or next stroke, the
Les dispositifs décrits peuvent également être utilisés d'une autre manière permettant d'enfoncer le clou avec une seule main. Pour ce faire, le clou est saisi par le dispositif selon l'invention de la même manière qu'indiqué plus haut. Une fois la tête 14 du clou 16 en contact contre la protection 6, 26, 36 il est possible de venir frapper le clou sur la surface dans laquelle il doit être planté. Le geste effectué par l'utilisateur correspond sensiblement à celui que l'on réalise lorsqu'on donne un coup de poing sur une table. Le clou 16 est alors partiellement enfoncé. En retirant le dispositif selon l'invention il suffit alors de venir frapper la tête 14 du clou 16 avec la partie à frapper 10, 30, 40. On peut ainsi terminer l'enfoncement du clou sans utiliser de marteau.The described devices can also be used in another way to drive the nail with one hand. To do this, the nail is grasped by the device according to the invention in the same manner as indicated above. Once the
Ce second procédé d'utilisation d'un dispositif selon l'invention ne permet pas de planter des clous avec une aussi bonne précision que le premier procédé décrit. Toutefois avec un peu d'expérience, il est possible d'obtenir une assez bonne précision surtout qu'en général des clous sont positionnés avec moins de précision qu'une vis.This second method of using a device according to the invention does not make it possible to plant nails with as good a precision as the first method described. However with a little experience, it is possible to obtain a good enough accuracy especially that in general nails are positioned with less precision than a screw.
Le dispositif selon l'invention peut aussi être utilisé avec des vis. Il suffit alors de prévoir au niveau de la protection 6 ; 26 ; 36 une saillie (non représentée) s'étendant vers l'intérieur de la virole 8 ; 28 ; 38. Cette saillie présente alors la forme d'un embout de tournevis. Lorsqu'une vis est attirée vers l'aimant 4 ; 24 ; 34 et que sa tête vient prendre appui contre la protection 6 ; 26 ; 36, la vis étant guidée lors de son déplacement vers l'aimant 4 ; 24 ; 34 par la virole 8 ; 28 ; 38, en tournant le manche 2 ; 22 ; 32, la saillie vient coopérer avec la tête de la vis pour réaliser le vissage de celle-ci.The device according to the invention can also be used with screws. It is then sufficient to provide at the level of the
Cette forme de réalisation, avec un embout de tournevis intégré à la protection 6 ; 26 ; 36, est avantageuse notamment dans le cas d'une virole interchangeable (
Le dispositif selon l'invention peut également de trouver d'autres applications. Ainsi par exemple, pour des personnes ayant des problèmes d'articulation dans les doigts, on peut prévoir d'équiper un gobelet avec une tige en matériau magnétique. Cette tige est alors utilisée comme poignée. Son diamètre est par exemple adapté au diamètre intérieur de la virole 8, 28, 38. La personne ayant des problèmes pour maintenir un gobelet peut alors utiliser le dispositif selon l'invention pour venir attirer la tige associée au gobelet. Le dispositif selon l'invention sert alors de dispositif de préhension pour ce gobelet.The device according to the invention can also find other applications. For example, for people with problems of articulation in the fingers, it is expected to equip a cup with a rod of magnetic material. This rod is then used as a handle. Its diameter is for example adapted to the inner diameter of the
La présente invention ne se limite pas aux formes de réalisation décrites ci-dessus à titre d'exemples non limitatifs. Elle concerne au contraire toutes les variantes de réalisation à la portée de l'homme du métier dans le cadre des revendications ci-après.The present invention is not limited to the embodiments described above by way of non-limiting examples. On the contrary, it concerns all the variants that are within the reach of those skilled in the art in the context of of the claims below.
