Cet outillage comporte une gaine 7 en forme d'entonnoir cylindrique d'axe zzl qui est surmonté d'un soufflet 2 sur lequel s'insert des moyens qui permettent de la fixer contre un carter, autour du bouchon de vidange.The following description refers to the appended drawings which represent, without any limiting character, an example of embodiment of a hand tool according to the invention
- Figure 1 is an exploded view
- Figure 2 an axial section of a tool according to the invention
- Figure 3 a partial section along III III of Figure 2
Figure I shows an exploded view of the essential parts of a preferred embodiment of a tool according to the invention
This tool comprises a sheath 7 in the form of a cylindrical funnel with a zzl axis which is surmounted by a bellows 2 on which is inserted means which make it possible to fix it against a casing, around the drain plug.

Ces moyens de fixation sont constitués, par exemple, d'un aimant permanent 3 en forme de couronne qui adhère contre la paroi metallique du carter, dans le cas ou celui ci est en matériau ferro-magnétique. These fixing means consist, for example, of a permanent magnet 3 in the form of a crown which adheres against the metal wall of the casing, in the case where the latter is made of ferro-magnetic material.

La partie inférieure dudit entonnoir est composee d'un fourreau permettant le passage de la clé. La diametrie intérieure du fourreau correspond au diamètre exterieur de la clé tout en constituant une étanchéité parfaite entre la clé e+ 1 T entonnoir.  The lower part of said funnel is composed of a sheath allowing the passage of the key. The inner diameter of the sleeve corresponds to the outside diameter of the key while constituting a perfect seal between the key e + 1 T funnel.

L'outIllage selon la figure 1 comporte, en outre, une cl 5 ui est un tube creux cylindrique qui s'engage dans le fourreau 4. L'extrémité supérieure de la clé 5 porte une tête 6 de section carrée qui s'engage dans le logement du bouchon de vidange fileté pour dévisser celui-ci. La tête 6 est interchangeable et peut être une tête creuse pour bouchon en relief. The tool according to FIG. 1 further comprises a key 5 which is a hollow cylindrical tube which engages in the sheath 4. The upper end of the key 5 carries a head 6 of square section which engages in the threaded drain plug housing to unscrew it. The head 6 is interchangeable and can be a hollow head for a relief cap.

La clé est percée de part en part autour d'un axe xxl horizontal, les orifices 7 dits d'évacuation permettent l'écoulement de l'huile à l'intérieur du tube que forme la clé 5. The key is drilled right through around a horizontal axis xxl, the so-called discharge orifices 7 allow the oil to flow inside the tube formed by the key 5.

La section de l'extrémité inférieure de la clé 5 est carrée de telle sorte qu'on puisse engager une clé plate à fourche, pour tourner la clé 5 qui desserre le bouchon de vidange.  The section of the lower end of the key 5 is square so that an open-ended open-end wrench can be engaged to turn the key 5 which loosens the drain plug.

La figure 2 représente la coupe axiale passant par l'axe zz1 de la cle 5 de 1' outillage selon l'invention en position pret à démonter un bouchon de vidange 8 qui est vissé dans un orifice de vidange fileté d'un carter dThuile 9. Dans cet exemple, l'axe du bouchon 8 est vertical, mais il pourrait egalement être horizontal ou incliné. FIG. 2 represents the axial section passing through the axis zz1 of the key 5 of the tool according to the invention in the position ready to dismantle a drain plug 8 which is screwed into a threaded drain orifice of an oil pan 9 In this example, the axis of the plug 8 is vertical, but it could also be horizontal or inclined.

La figure 3 est une coupe selon III III de la figure 2 sur laquelle on voit la section carrée de l'extrémité inférieure de la clé 5. FIG. 3 is a section on III III of FIG. 2 in which we see the square section of the lower end of the key 5.

L'utilisation d'un outillage selon l'invention comporte les étapes suivantes
On place a l'extrémité supérieure de la clé 5 une tête 6 qui correspond au bouchon 8 à dévisser et on engage cette têtue sur le dit bouchon. Après quoi, on applique l'ouverture de l'entonnoir 1 contre la paroi du carter 9 dans lequel se trouve le bouchon de vidange 8. La clé 5 sert donc de entrage de l'entonnoir 7 qui enveloppe le bouchon et qu est maintenu en place par la couronne aimantee 3. The use of a tool according to the invention comprises the following steps
A head 6 which corresponds to the plug 8 to be unscrewed is placed at the upper end of the key 5 and this stubborn is engaged on said plug. After which, the opening of the funnel 1 is applied against the wall of the casing 9 in which the drain plug 8 is located. The key 5 therefore serves as an inlet for the funnel 7 which envelops the plug and is kept in place. placed by the magnetic crown 3.

l'aide d'une clé plate à fourche que l'on engage perpendiculacelle-ci en rotation afin de debloquer le bouchon de vidange. using an open-ended open-end wrench that is engaged perpendicularly to rotate the drain plug.

La clé 5 tourne librement à l'intérieur du fourreau 4 de l'entonnoir 1 qui reste fixe. The key 5 turns freely inside the sheath 4 of the funnel 1 which remains fixed.

Une fois que le bouchon 5 a été suffisamment débloque, on finit de dévisser le bouchon 8 en faisant tourner manuellement la cle 5.  Once the plug 5 has been sufficiently released, we finish unscrewing the plug 8 by manually turning the key 5.

Lorsque le bouchon 8 est dévissé, la clé plus l'entonnoir se déplacent vers le bas grâce à I'extention du soufflet que constitue la partie supérieure de l'entonnoir et le bouchon reste au fond de l'entonnoir. When the plug 8 is unscrewed, the key plus the funnel move downwards thanks to the extension of the bellows which constitutes the upper part of the funnel and the plug remains at the bottom of the funnel.

L'huile s'écoule dans l'entonnoir i et passe par les trous d'évacuation 7 de la clé 5 et achève sont acheminement à l'intérieur de la clé 5. The oil flows into the funnel i and passes through the drainage holes 7 of the key 5 and completes its routing inside the key 5.

L'écoulement de l'huile est représentée par les fleches sur le croquis 2. The flow of oil is represented by the arrows in sketch 2.

On place enfin un récipient sous l'extrémité de la clé 5 afin de récupérer l'huile.  Finally, a container is placed under the end of the key 5 in order to recover the oil.

La description précédente se réfère à l'exemple d'un bouchon de vidange d'un carter d'huile. Il est précisé que cette application n'est pas limitative et qu'un outillage selon l'invention peut etre utilisé pour démonter tout autre bouchon de vidange en évitant de se salir ou de salir les locaux. The preceding description refers to the example of an oil pan drain plug. It is specified that this application is not limiting and that a tool according to the invention can be used to dismantle any other drain plug while avoiding soiling or soiling the premises.

Un dispositif selon l'invention peut également servir à dévisser, par exemple, un bouchon d'un réservoir de liquide, par exemple d'une cuve à mazout pour prélever proprement un échantillon. A device according to the invention can also be used to unscrew, for example, a cap from a liquid tank, for example from an oil tank to cleanly take a sample.

Selon une variante la tete n06 peut etre fixée sur un pivot. Grâce au basculement de la tête, on obtient deux têtes différentes : par exemple, un carré de 8 mm et un de 10 mm.  According to a variant the head n06 can be fixed on a pivot. Thanks to the tilting of the head, two different heads are obtained: for example, an 8 mm square and a 10 mm square.
