Abstract
Description
Outil tel que burin, pointerolle pourvu d'un dispositif de protection.Tool such as chisel, chisel provided with a protective device.
La présente invention concerne outil tel que burin et pointerolle pourvu d'un dispositif de protection. The present invention relates to tool such as chisel and chisel provided with a protective device.
io Les outils tels que les burins ou les pointerolles sont généralement employés dans le domaine du bâtiment, en particulier utilisés par les maçons. Ces outils sont utilisés avec un marteau, l'utilisateur tapant d'une main avec son marteau sur le burin ou la pointerolle qu'il tient de l'autre main. Tools such as chisels or pointerolles are generally employed in the field of building, in particular used by masons. These tools are used with a hammer, the user tapping with one hand with his hammer on the chisel or the chisel he holds with the other hand.
La frappe de l'outil par le marteau engendre des vibrations dans le burin ou la pointerolle, qui se répercutent dans la main et le bras de l'utilisateur. De telles vibrations sont inconfortables pour l'utilisateur, voire néfastes. En effet, de telles vibrations induisent une fatigue de l'utilisateur ce qui peut engendrer des risques d'accidents, liées à la fatigue du bras ou de la main de l'utilisateur. The striking of the tool by the hammer generates vibrations in the chisel or chisel, which reverberate in the hand and the arm of the user. Such vibrations are uncomfortable for the user, even harmful. Indeed, such vibrations induce fatigue of the user which can cause the risk of accidents related to fatigue of the arm or the hand of the user.
On a proposé l'utilisation en place des pare coup de protection. Cependant, un pare coup présente des inconvénients, en ce qu'il ne permet pas de voir où l'on tape. It has been proposed to use protective shields in place. However, a pare-coup has drawbacks, in that it does not allow to see where you type.
La présente invention a donc pour but de proposer un outil tel que burin ou pointerolle pourvu d'un dispositif de protection contre les vibrations ne présentant pas cet inconvénient. The present invention therefore aims to provide a tool such as chisel or chisel provided with a vibration protection device does not have this disadvantage.
A cet effet, la présente invention a pour objet un outil tel que burin ou pointerolle comportant un dispositif de protection, caractérisé en ce que ledit dispositif de protection est constitué d'un manchon constitué d'une matière naturelle ou synthétique, assemblé sur le burin ou la pointerolle. For this purpose, the present invention relates to a tool such as chisel or chisel having a protection device, characterized in that said protective device consists of a sleeve consisting of a natural or synthetic material, assembled on the chisel or the chisel.
2 2859936 Ainsi de manière avantageuse, le manchon associé au burin ou à la pointerolle permet donc un meilleur confort de travail et une meilleure prise en main de l'outil. 2 2859936 Thus advantageously, the sleeve associated with the chisel or chisel therefore allows a better working comfort and a better grip of the tool.
De préférence, le matériau synthétique constituant le manchon de l'outil selon l'invention présente des qualités d'absorption des vibrations. Preferably, the synthetic material constituting the sleeve of the tool according to the invention has vibration absorption qualities.
Le manchon peut être réalisé en matière synthétique telle que du chlorure de polyvinyle (PVC), du caoutchouc nitrile butadiène (NBR) ou en une matière io naturelle telle que du caoutchouc naturel comportant éventuellement un mélange d'additifs appropriés. The sleeve may be made of synthetic material such as polyvinyl chloride (PVC), nitrile butadiene rubber (NBR) or a natural material such as natural rubber optionally comprising a mixture of suitable additives.
On réduit ainsi avantageusement les accidents éventuels et on atténue la fatigue due à l'effort. De plus, l'outil ergonomique obtenu selon l'invention permet de voir 15 où l'on tape et est agréable à utiliser. This advantageously reduces the possible accidents and reduces fatigue due to effort. In addition, the ergonomic tool obtained according to the invention makes it possible to see where it is typed and is pleasant to use.
On décrira maintenant l'invention plus en détail en référence au dessin dans lequel: la figure 1 représente une vue en perspective d'un outil équipé d'un dispositif de protection selon l'invention; et la figure 2 représente une vue en perspective d'un outil et du dispositif selon l'invention avant mise en place de ce dernier. The invention will now be described in more detail with reference to the drawing in which: FIG. 1 shows a perspective view of a tool equipped with a protection device according to the invention; and Figure 2 shows a perspective view of a tool and the device according to the invention before introduction of the latter.
Comme on peut le voir dans la figure 1, l'outil tel qu'un burin 1 est réalisé de préférence à partir d'une barre d'acier octogonale, coupée aux dimensions requises. As can be seen in Figure 1, the tool such as a chisel 1 is preferably made from an octagonal steel bar, cut to the required dimensions.
La tête du burin 1 est ensuite forgée, puis la pointe est meulée. On réalise ensuite un thermo-traitement de l'outil, un polissage et un trempage. The head of the chisel 1 is then forged, then the tip is ground. The thermo-treatment of the tool is then carried out, polishing and soaking.
3 2859936 On a également réalisé un manchon 2 en caoutchouc naturel, renfermant éventuellement un mélange d'additifs. Ce manchon 2 présente une forme extérieure ovoïde sensiblement allongée. De préférence, le diamètre intérieur du manchon 2 correspond sensiblement au diamètre extérieur de l'outil 1. A sleeve 2 made of natural rubber, possibly containing a mixture of additives, was also produced. This sleeve 2 has a substantially elongated outer ovoid shape. Preferably, the inside diameter of the sleeve 2 substantially corresponds to the outside diameter of the tool 1.
Lorsque l'outil 1 est prêt, le manchon est de préférence plongé dans l'eau chaude quelques minutes. When the tool 1 is ready, the sleeve is preferably immersed in hot water for a few minutes.
Il est ensuite assemblé sur l'outil 1.par le haut de l'outil, puis ajusté sur ledit outil io 1; par exemple il est mis en position en partant du haut comme cela est visible sur la figure 2. It is then assembled on the tool 1. by the top of the tool, then fitted on said tool 1; for example it is set in position from the top as can be seen in Figure 2.
De préférence, le manchon 2 est obtenu par exemple, par moulage de la matière naturelle et présente une surface extérieure granuleuse pour offrir une meilleure 15 prise à l'utilisateur évitant en particulier les glissements. Preferably, the sleeve 2 is obtained for example by molding the natural material and has a granular outer surface to provide better grip to the user especially avoiding slippage.
