Description
La présente invention a pour objet un outil manuel à percussion pour le déblocage en particulier de cônes morses à inertie du type comportant un manche oblong sur lequel coulisse une masse cylindrique de percussions. The present invention relates to a manual percussion tool for unlocking in particular walrus cones with inertia of the type comprising an oblong handle on which slides a cylindrical mass of percussion.
Dans ce qui suit on décrira une application spécifique au déblocage de cônes morses. On comprendra que l'outil de l'invention peut être utilisé à d'autres fins en prévoyant des extrémités actives différentes, par exemple pour le sertissage, l'emporte pièce, le cloutage, le limage, le sciage et de manière plus générale toute action travaillant par choc.. In what follows, a specific application will be described for unlocking walrus cones. It will be understood that the tool of the invention can be used for other purposes by providing different active ends, for example for crimping, punching, nailing, filing, sawing and more generally any shock working action ..
Des outils de ce type ont déjà fait l'objet par exemple des brevets FR 922 621 et FR 2 327 848. Ils sont de conception complexe et présentent en outre l'inconvénient de mettre en oeuvre toujours la même puissance, celle-ci étant déterminée de fabrication par le choix des ressorts. En outre, la lame de travail qui sert à dégager le cône peut se coincer facilement. De plus le mécanisme de commande n'est pas protégé il peut donc être détérioré et présente un risque physique pour l'utilisateur. Enfin dans le dispositif du FR 2 327 848 l'utilisateur doit à un moment donné utiliser ses deux mains pour le faire fonctionner. Tools of this type have already been the subject, for example, of patents FR 922 621 and FR 2 327 848. They are of complex design and also have the drawback of always using the same power, this being determined of manufacturing by the choice of springs. In addition, the working blade used to clear the cone can get stuck easily. In addition the control mechanism is not protected so it can be damaged and presents a physical risk for the user. Finally in the device of FR 2 327 848 the user must at one point use his two hands to operate it.
L'invention a pour objet de remédier à ces inconvénients. The object of the invention is to remedy these drawbacks.
Conformément à l'invention, ce résultat est obtenu avec un outil manuel à percussion pour le déblocage en particulier de cônes morses à inertie du type comportant un manche oblong sur lequel coulisse une masse cylindrique de percussion, caractérisé en ce que la masse cylindrique est actionnée en translation manuellement par l'utilisateur, à l'encontre d'un ressort de rappel disposé à l'intérieur dudit manche et relié mécaniquement à ladite masse. According to the invention, this result is obtained with a manual percussion tool for unlocking in particular walrus cones with inertia of the type comprising an oblong handle on which slides a cylindrical percussion mass, characterized in that the cylindrical mass is actuated in translation manually by the user, against a return spring disposed inside said handle and mechanically connected to said mass.
On comprendra mieux l'invention à l'aide de la description faite ci-après d'un mode de mise en oeuvre donné à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels - la figure 1 est une vue en élévation latérale d'un outil conforme à l'invention, en position d'utilisation - la figure 2 est une vue en coupe longitudinale partielle selon A-A de dessus de l'outil de la figure 1. The invention will be better understood with the aid of the description given below of an embodiment given by way of nonlimiting example, with reference to the appended drawings in which - FIG. 1 is an elevation view side view of a tool according to the invention, in the position of use - FIG. 2 is a view in partial longitudinal section along AA from above of the tool of FIG. 1.
L'outil, généralement référencé (12), comporte une lame il) en acier trempé avec une pente de 20 % par rapport à l'axe principal. The tool, generally referenced (12), comprises a blade 11) of hardened steel with a slope of 20% relative to the main axis.
Un manche creux (2) en acier doux est fixé à la lame (1), par soudure ou montage mécanique. Une rainure longitudinale (13) est usinée dans le manche (2). A hollow handle (2) made of mild steel is fixed to the blade (1), by welding or mechanical assembly. A longitudinal groove (13) is machined in the handle (2).
Une masse cylindrique (3) alésée en son centre sur toute la longueur est engagée sur le manche (2). A cylindrical mass (3) bored in its center over the entire length is engaged on the handle (2).
Une chape (4) sert de butée au repos de la masse (3) et à accrocher l'outil par un anneau (14). A yoke (4) serves as a stop for the rest of the mass (3) and for hanging the tool by a ring (14).
Deux ressorts antagonistes (7) sont montés en série à l'intérieur du manche t2) par l'intermédiaire d'une entretoise, ceci pour limiter l'encombrement. Two opposing springs (7) are mounted in series inside the handle t2) by means of a spacer, this to limit the size.
La vis (5) traverse la chape (4), et l'extrémité du manche (2) et la pièce (9) qui maintient le ressort (7). The screw (5) passes through the yoke (4), and the end of the handle (2) and the part (9) which holds the spring (7).
La masse (3) du côte de la lame comporte un trou taraudé avec chambrage pour y loger une vis (6). The mass (3) on the side of the blade has a tapped hole with a recess to accommodate a screw (6).
Cette vis (6) comporte un décolletage pour guidage dans la rainure (13) du manche (2), et un décolletage plus petit qui va s'engager transversalement dans la pièce t8) qui est solidaire du ressort (7). This screw (6) includes a turning for guiding in the groove (13) of the handle (2), and a smaller turning which will engage transversely in the part t8) which is integral with the spring (7).
La figure 1 représente l'extracteur de cône au repos, ressorts (7) détendus et masse (3) contre la chape (4). Figure 1 shows the cone extractor at rest, springs (7) relaxed and mass (3) against the yoke (4).
Pour l'utilisation, l'opérateur saisit l'appareil par la masse (3), introduit la lame (1) dans la lumière du cône femelle (11), l'axe principal de l'appareil doit être perpendiculaire à l'axe du cône. For use, the operator grasps the device by mass (3), introduces the blade (1) into the lumen of the female cone (11), the main axis of the device must be perpendicular to the axis of the cone.
La pente de la lame (1) en appui sur le tenon du cône mâle (10), l'opérateur fait glisser vivement sans lâcher la masse (3) qui va frapper la base de la lame (1) et sépare les cônes. The slope of the blade (1) resting on the tenon of the male cone (10), the operator slides quickly without releasing the mass (3) which will strike the base of the blade (1) and separate the cones.
Le rappel de la masse se fait par le ressort (7). The mass is returned by the spring (7).
Le gabarit de l'appareil est prévu pour le démontage des cônes numéro deux à numéro quatre. The template of the device is intended for the dismantling of the cones number two to number four.
Ce système est rapide et permet une action directionnelle optimale. Le déclenchement manuel permet à l'utilisateur de moduler la puissance. Il est simple, fonctionnel, pratique et d'un prix de revient peu élevé. This system is fast and allows optimal directional action. Manual triggering allows the user to modulate the power. It is simple, functional, practical and of a low cost price.
