Abstract

The handle fixing is made from a metal blank which is rolled into a tubular sleeve (4) into which the handle (2) is fitted. Each of the two facing edges (7,8) of the sleeve have a part forming a locking key (11) in the form of a dovetail which prevents the edges from moving tangentially. Inside the sleeve are longitudinal ribs angularly divided on its internal periphery. In the thickness of these ribs the sleeve is tapped to allow fastening the handle.

Description

L'invention se rapporte à dispositif de fixation d'un manche sur le corps d'un outil, tel un balai ou une raclette.The invention relates to a device for fixing a handle to the body of a tool, such as a broom or a squeegee.

Classiquement, un tel dispositif de fixation comprend :

  • un manchon tubulaire dans lequel s'emboite l'extrémité du manche,
  • des moyens de verrouillage du manche dans le manchon et
  • des moyens d'association du manchon avec le corps de l'outil.
Conventionally, such a fixing device comprises:
  • a tubular sleeve into which the end of the handle fits,
  • means for locking the handle in the sleeve and
  • means of association of the sleeve with the body of the tool.

Il existe plusieurs procédés pour obtenir ces dispositifs de fixation.There are several methods for obtaining these fasteners.

Pour mémoire, on citera, par exemple, les dispositifs de fixation obtenus par moulage d'une matière plastique.For the record, mention will be made, for example, of the fixing devices obtained by molding a plastic material.

L'invention intéresse plus précisement les dispositifs de fixation qui ne sont pas obtenus par moulage et notamment les dispositifs métalliques.The invention relates more precisely to fixing devices which are not obtained by molding and in particular metal devices.

On connait (FR-A-2.147.375) un dispositif de fixation constitué d'un tronçon de tube applati en l'une de ses extrémités puis plié pour former une platine prenant appui sur le dos d'une brosse pour former un balai.We know (FR-A-2,147,375) a fixing device consisting of a section of tube flattened at one of its ends and then folded to form a plate bearing on the back of a brush to form a broom.

Un tel dispositif est relativement simple à réaliser mais le tube utilisé étant un produit semi-fini est assez couteux.Such a device is relatively simple to produce, but the tube used being a semi-finished product is quite expensive.

En outre, comme la largeur de la platine dépend de la section du tube, si cette platine est suffisante pour des petits outils, elle ne procure pas un appui suffisamment stable pour des outils plus large.In addition, as the width of the plate depends on the section of the tube, if this plate is sufficient for small tools, it does not provide a sufficiently stable support for larger tools.

On connait également (FR-A-2.147.374) un dispositif de fixation comprenant un troncon de tube fixé par des cordons de soudure sur une platine de dimensions appropriées.There is also known (FR-A-2,147,374) a fixing device comprising a section of tube fixed by weld beads on a plate of appropriate dimensions.

Si ce dispositif remédie au problème précité, il est encore plus couteux du fait de l'opération de soudure nécessaire pour assembler les deux parties.If this device remedies the aforementioned problem, it is even more expensive because of the welding operation necessary to assemble the two parts.

Il faut également que l'épaisseur du tube et de la platine soit suffisante pour que les pièces soient facilement soudables.It is also necessary that the thickness of the tube and the plate is sufficient so that the parts are easily weldable.

On connait aussi un dispositif de fixation formé à partir d'un flan de métal mis en forme par déformation localisée pour au delà d'une platine former un manchon tubulaire par roulement et rapprochement local des bords du flan.There is also known a fixing device formed from a metal blank shaped by localized deformation for beyond a plate form a tubular sleeve by rolling and local approximation of the edges of the blank.

Cette solution est intéressante car la tôle est moins coûteuse que le tube et, pour modifier la taille de la platine, il suffit de modifier la taille de la partie correspondante du flan.This solution is interesting because the sheet is less expensive than the tube and, to modify the size of the plate, it suffices to modify the size of the corresponding part of the blank.

Ce type de dispositif présente toutefois un inconvénient : on n'arrive pas à maintenir le manche dans le manchon uniquement par l'ajustement lié à la différence de diamètre entre celui du manche et celui intérieur au manchon car sous l'effet de la contrainte les bords de la partie tubulaire de la pièce s'éloignent.However, this type of device has a drawback: it is not possible to keep the handle in the sleeve only by the adjustment linked to the difference in diameter between that of the handle and that inside the sleeve because under the effect of the stress the edges of the tubular part of the part move away.

Enfin, on connait encore (FR-A-2.208.764) un dispositif du type précité pour lequel les bords de la partie tubulaire sont soudés entre eux.Finally, there is also known (FR-A-2,208,764) a device of the aforementioned type for which the edges of the tubular part are welded together.

Si cette solution permet de coincer le manche dans la douille, il nécessite une étape supplémentaire de fabrication et un coût majoré par celui de cette soudure.If this solution makes it possible to wedge the handle in the socket, it requires an additional manufacturing step and a cost increased by that of this welding.

Un des résultats que l'invention vise à obtenir est un dispositif de fixation du type cité plus haut qui remédie à ces inconvénients.One of the results which the invention aims to obtain is a fixing device of the type mentioned above which overcomes these drawbacks.

A cet effet, l'invention a pour objet un tel dispositif notamment caractérisé en ce que chacun des deux bords en vis à vis du manchon tubulaire présente au moins une fraction d'une clé de verrouillage qui, par coopération de forme, interdit aux dits bords de s'éloigner selon une direction tangente aux dits bords.To this end, the subject of the invention is such a device, in particular characterized in that each of the two opposite edges of the tubular sleeve has at least a fraction of a locking key which, by form cooperation, prevents said edges to move away in a direction tangent to said edges.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :

  • figure 1 : une vue de dessous d'un balai,
  • figure 2 : une vue d'un détail de la figure 1,
  • figure 3 : une vue développée d'un dispositif de fixation.
The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the attached drawing which schematically represents:
  • Figure 1: a bottom view of a broom,
  • FIG. 2: a view of a detail of FIG. 1,
  • Figure 3: a developed view of a fixing device.

En se reportant au dessin, on voit que, pour fixer un manche 2 à un outil 1, tel une raclette ou un balai, on fait appel à un dispositif de fixation 3.Referring to the drawing, it can be seen that, to fix a handle 2 to a tool 1, such as a squeegee or a broom, a fixing device 3 is used.

Classiquement, un tel dispositif de fixation comprend :

  • un manchon tubulaire 4, dans lequel s'emboite l'extrémité du manche,
  • des moyens 5 de verrouillage du manche 2 dans le manchon et
  • des moyens d'association du manchon avec le corps de l'outil.
Conventionally, such a fixing device comprises:
  • a tubular sleeve 4, into which the end of the handle fits,
  • means 5 for locking the handle 2 in the sleeve and
  • means of association of the sleeve with the body of the tool.

De manière classique, ce dispositif de fixation est réalisé à partir d'un flan de métal localement mis en forme par roulement pour au delà d'une platine 6 obtenir un manchon tubulaire par rapprochement des bords 7, 8 de la partie du flan ainsi roulée.Conventionally, this fixing device is produced from a metal blank locally shaped by rolling for beyond a plate 6 to obtain a tubular sleeve by bringing the edges 7, 8 of the part of the blank thus rolled .

La platine 6 est associée au corps de l'outil par tous moyens connus compatibles avec le matériau de l'outil, tels des rivets ou des soudures par points etc ...The plate 6 is associated with the body of the tool by any known means compatible with the material of the tool, such as rivets or spot welds, etc.

Selon l'invention, chacun des deux bords 7, 8 en vis à vis du manchon tubulaire présente au moins une fraction 9, 10 d'une clé de verrouillage 11 qui, par coopération de forme, interdit aux dits bords 7, 8 de s'éloigner selon une direction tangente aux dits bords.According to the invention, each of the two edges 7, 8 facing the tubular sleeve has at least a fraction 9, 10 of a locking key 11 which, by form cooperation, prevents said edges 7, 8 from s 'move away in a direction tangent to said edges.

Dans une forme préférée de réalisation de l'invention :

  • l'un des bords en vis à vis du manchon tubulaire comprend au moins une encoche 10 de forme prédéterminée et,
  • l'autre bord présente en regard de cette découpe une patte 9 de forme complémentaire à la dite découpe, les patte 9 et découpe 10 étant conçues de manière à permettre à la patte 9 de s'engager dans la découpe que selon une direction sensiblement orthogonale à cette découpe.
In a preferred embodiment of the invention:
  • one of the edges facing the tubular sleeve comprises at least one notch 10 of predetermined shape and,
  • the other edge has, opposite this cutout, a tab 9 of shape complementary to said cutout, the tab 9 and cut 10 being designed so as to allow the tab 9 to engage in the cut only in a direction substantially orthogonal to this cut.

Par exemple, la découpe et la patte auront une forme en queue d'aronde.For example, the cutout and the tab will have a dovetail shape.

Ceci est intéressant car, lorsque la machine roule le métal pour former le manchon tubulaire, elle vient automatiquement placer la patte dans la découpe et ainsi verrouiller sans opération supplémentaire les bords du manchon.This is interesting because, when the machine rolls the metal to form the tubular sleeve, it automatically places the tab in the cutout and thus lock the edges of the sleeve without any additional operation.

De préférence, le manchon présente à l'intérieur des nervures 12 longitudinales réparties angulairement sur la périphérie interne du manchon et, dans l'épaisseur de ces nervures 12, le manchon est taraudé pour permettre aussi d'ancrer un manche en matériau tendre.Preferably, the sleeve has inside the longitudinal ribs 12 angularly distributed over the internal periphery of the sleeve and, in the thickness of these ribs 12, the sleeve is tapped to also allow to anchor a handle made of soft material.
