Description

La présente invention a trait à un dispositif d'emmanchement servant à fixer un manche à un outil, c'est-à-dire, en particulier, à un dispositif se prêtant à 'la fixation facile et efficace d'un manche à un outil, mais susceptible d'en être démonté facilement, par exemple en vue de sa fixation à un autre outil. Il pourra s'agir d'un outil de nature quelconque, tel qu'une brosse, un râteau ou autre.The present invention relates to a fitting device for fixing a handle to a tool, that is to say, in particular, to a device suitable for ' easy and effective fixing of a handle to a tool , but capable of being easily dismantled therefrom, for example with a view to fixing it to another tool. It could be a tool of any kind, such as a brush, a rake or the like.

On connaît des dispositifs d'emmanchement se prêtant à l'assemblage rapide d'un manche et d'un outil. Ces dispositifs d'emmanchement connus présentent toutefois l'inconvénient de ce qu'ils sont munis d'un simple moyen de serrage, susceptible d'être serré, de sorte que la jonction réalisée à l'aide de ces dispositifs d'emmanchement connus est peu fiable.There are known fitting devices suitable for rapid assembly of a handle and a tool. These known fitting devices, however, have the disadvantage that they are provided with a simple clamping means, capable of being tightened, so that the junction produced using these known fitting devices is unreliable.

C'est pour remédier à l'inconvénient susmentionné des systèmes d'emmanchement connus, que la présente invention vise la réalisation d'un système d'emmanchement perfectionné, mettant en oeuvre, d'une part, des moyens de fixation et, d'autre part, des moyens de serrage supplémentaires, tout cela de manière à réaliser un dispositif d'emmanchement double, se distinguant par une grande efficacité et fiabilité.It is to remedy the aforementioned drawback of known fitting systems, that the present invention aims to produce an improved fitting system, using, on the one hand, fixing means and, on the other hand, additional clamping means, all this so as to produce a double fitting device, distinguished by high efficiency and reliability.

A cet effet, l'invention a pour objet un système d'emmanchement essentiellement caractérisé par la combinaison d'un premier élément creux, susceptible d'être fixé à l'outil ou bien en faisant partie, et muni de moyens de fixation servant à fixer le manche dans sa partie creuse, ainsi que de moyens de serrage supplémentaires, susceptibles d'être serrés, et de filet mâle: et d'un deuxième élément se présentant sous forme d'un bouchon taraudé, susceptible, d'une part, d'être glissé sur le manche et, d'autre part, de coopérer avec ledit premier élément pour serrer les moyens de serrage autour du manche.To this end, the subject of the invention is a fitting system essentially characterized by the combination of a first hollow element, capable of being fixed to the tool or else forming part of it, and provided with fixing means serving to fix the handle in its hollow part, as well as additional tightening means, capable of being tightened, and of male thread: and of a second element in the form of a threaded plug, susceptible, on the one hand, to be slid over the handle and, on the other hand, to cooperate with said first element to tighten the tightening means around the handle.

Les caractéristiques et avantages du système selon l'invention ressortiront-plus clairement de la description détaillée suivante d'un mode d'exécution préféré, donnée exclusivement à titre d'exemple sans la moindre intention restrictive, avec référence au dessin annexé, où

  • la figure 1 représente le dispositif d'emmanchement à l'état dévissé;
  • la figure 2 représente une coupe du dispositif selon la figure 1, pratiqué suivant la ligne 11-11 de cette dernière; et
  • la figure 3 représente le dispositif d'emmanchement concerné à l'état monté.
The characteristics and advantages of the system according to the invention will emerge more clearly from the following detailed description of a preferred embodiment, given exclusively by way of example without any restrictive intention, with reference to the appended drawing, where
  • Figure 1 shows the fitting device in the unscrewed state;
  • 2 shows a section of the device according to Figure 1, made along line 11-11 thereof; and
  • FIG. 3 represents the fitting device concerned in the assembled state.

Comme le montrent les figures du dessin annexé, le dispositif d'emmanchement 1 y illustré se compose essentiellement d'un premier élément creux 2 et d'un deuxième élément 3 sous forme d'un bouchon taraudé.As shown in the figures of the appended drawing, the fitting device 1 illustrated therein essentially consists of a first hollow element 2 and a second element 3 in the form of a threaded plug.

Ledit premier élément 2 se présente essentiellement sous forme d'une pièce cylindrique creuse, munie à l'intérieur de moyens de fixation, tels qu'une denture ou un filet 4 se prêtant à la fixation d'un manche 5, qui peut y être vissé ou pressé, selon le mode d'exécution. Le diamètre moyen D de la denture 4 diminue, de préférence, graduellement vers le bas.Said first element 2 is essentially in the form of a hollow cylindrical part, provided inside with fixing means, such as a toothing or a thread 4 suitable for fixing a handle 5, which can be there screwed or pressed, depending on the mode of execution. The average diameter D of the teeth 4 preferably decreases gradually downwards.

Le premier élément 2 est, à son extrémité inférieure 6, fixé à un outil ou venu d'une pièce avec lui. Dans le mode d'exécution ici décrit et représenté, l'extrémité 6 de l'élément 2 coopère avec un alésage 7, pratiqué dans un corps de brosse 8, et y est fixé par exemple par collage et/ou par serrage, dans ce dernier cas éventuellement à l'aide de crochets ou d'autres éléments analogues.The first element 2 is, at its lower end 6, fixed to a tool or come in one piece with it. In the embodiment described and shown here, the end 6 of the element 2 cooperates with a bore 7, formed in a brush body 8, and is fixed to it, for example by gluing and / or by clamping, in this last case possibly by means of hooks or other similar elements.

Le premier élément 2 est, à son autre extrémité 9, muni de moyens de serrage, susceptibles d'être serrés et se prééen- tant sous forme de languettes élastiques 10 pliables radialement, mais orientées axialement. Ce premier élément 2 est à sa surface extérieure muni de filet mâle 11.The first element 2 is, at its other end 9, provided with clamping means, capable of being clamped and taking place in the form of elastic tongues 10 which can be folded radially, but oriented axially. This first element 2 is on its outer surface provided with a male thread 11.

Ledit deuxième élément 3 se présente essentiellement sous forme d'un bouchon taraudé, muni d'un alésage axial 12, .de manière qu'il s'adapte parfaitement sur le manche 3 et sur le premier élément 2. Ce deuxième élément èst taraudé, c'est-à-dire muni de filet femelle 13, susceptible de coopérer avec le filet mâle 11 du premier élément 2, et présente une partie conique 14 susceptible de coopérer avec les susdites languettes élastiques 10.Said second element 3 is essentially in the form of a threaded plug, provided with an axial bore 12,. So that it fits perfectly on the handle 3 and on the first element 2. This second element is tapped, that is to say provided with a female thread 13, capable of cooperating with the male thread 11 of the first element 2, and has a conical part 14 capable of cooperating with the above-mentioned elastic tongues 10.

La mise en oeuvre du dispositif d'emmanchement 1 est illustré clairement par les figures 1 et 3 du dessin annexé. Elle consiste essentiellement en ce que le manche-5 est fixé dans le premier élément 2 en le pressant et/ou vissant avec son extrémité dans ladite denture 4, après quoi le deuxième élément 3 est glissé sur le manche 5 et vissé sur le premier élément 2. Lors - du vissage, lesdites languettes sont serrées contre le manche 5 au moyen de ladite partie conique, tout cela de manière à réaliser une double liaison se distinguant par une grande efficacité et fiabilité.The implementation of the fitting device 1 is clearly illustrated by Figures 1 and 3 of the accompanying drawing. It essentially consists in that the handle-5 is fixed in the first element 2 by pressing it and / or screwing with its end in said toothing 4, after which the second element 3 is slid on the handle 5 and screwed on the first element 2. During - the screwing, the said tongues are pressed against the handle 5 by means of the said conical part, all this so as to produce a double bond which is distinguished by great efficiency and reliability.

Il va sans dire que l'invention ne se limite pas au mode de mise en oeuvre décrit à titre d'exemple dans les lignes précédentes et illustré par les figures du dessin annexé, mais prévoit toutes sortes d'exécutions du dispositif d'emmanchement concerné en ce qui concerne sa forme et ses dimensions, évidemment à condition de na pas dépasser le cadre de l'invention, défini par les revendications formulées ci-après.It goes without saying that the invention is not limited to the mode of implementation described by way of example in the preceding lines and illustrated by the figures in the appended drawing, but provides for all kinds of executions of the fitting device concerned. with regard to its shape and dimensions, obviously provided that it does not go beyond the scope of the invention, defined by the claims formulated below.
