Abstract

The subject of the invention relates to the technical field of hand tools. The spanner is noteworthy in that it comprises a lever arm 1, one part 1a of which forms a crank, one of the ends of the lever 1 being arranged with a reversible ratchet head 2 receiving, in a perpendicular manner, a socket 3, whilst the other end of the said lever 1 receives, coaxially, a recessed socket 4 identical to the previous one. The invention applies to all types of nut, in particular to motor vehicle wheel nuts.

Description

L'invention concerne une clé pour le serrage ou desserrage des éléments de fixation des roues de véhicules automobiles notamment. The invention relates to a key for tightening or loosening the fastening elements of motor vehicle wheels in particular.

L'objet de l'invention se rattache au secteur technique des outils à main, plus particulièrement des clés de serrage. The object of the invention relates to the technical sector of hand tools, more particularly tightening wrenches.

Généralement les serrage et desserrage des roues de véhicules, s'opèrent au moyen de vilebrequins qui équipent d'origine le véhicule. Lorsque les écrous sont trop bloqués ce type de clé s'avère nettement insuffisant et ne permet pas d'assurer le desserrage. Generally, the tightening and loosening of vehicle wheels is carried out by means of crankshafts which are originally fitted to the vehicle. When the nuts are tightened too much, this type of wrench is clearly insufficient and does not allow loosening.

Pour remédier à ces inconvénients, on a proposé d'autres types de clés, telles que les clés en croix, ou bien les éléments à cliquets. Les clés cruciformes sont encombrantes et d'un prix Se revient relativement élevé. Quant aux clés à cliquets , si elles sont relativement bien adaptées pour effectuer te déblocage initial de l'écrou, elle ne permettent pas, ou tout au moins pas dans des conditions satisfaisantes, le desserrage complet de l'écrou, ce qui nécessite d'employer une autre clé, par exemple le vilebrequin. To overcome these drawbacks, other types of keys have been proposed, such as cross keys, or ratchet elements. The cruciform keys are bulky and have a relatively high cost. As for the ratchet wrenches, if they are relatively well suited for carrying out the initial release of the nut, they do not allow, or at least not in satisfactory conditions, the complete loosening of the nut, which requires use another key, for example the crankshaft.

Le problème étant ainsi posé, l'invention s'est fixée pour but, d'une manière simple et efficace de réaliser un autre type de clé qui permet sans effort, d'une part, d'assurer le déblocage initial de l'écrou et, d'autre part, le desserrage complet dudit écrou et inversement. The problem being thus posed, the invention set itself the goal, in a simple and effective way of producing another type of key which makes it possible, without effort, on the one hand, to ensure the initial release of the nut and, on the other hand, the complete loosening of said nut and vice versa.

A cet effet, la clé est remarquable en ce qu'elle comprend un bras de levier dont une partie forme vilebrequin, l'une des extrémités du levier étant agencée avec une tête de cliquet réversible recevant d'une manière perpendiculaire une douille à empreinte, tandis que l'autre extrémité dudit levier reçoit d'une manière coaxiale une douille à empreinte identique à la précédente. To this end, the key is remarkable in that it comprises a lever arm of which a crankshaft-shaped part, one of the ends of the lever being arranged with a reversible ratchet head receiving perpendicularly an impression socket, while the other end of said lever receives in a coaxial manner an impression socket identical to the previous one.

L'invention est exposée ci-après plus en détail à l'aide des dessins qui représentent seulement un mode d'exécution. The invention is set out below in more detail with the aid of the drawings which represent only one embodiment.

La figure 1 est une vue à caractère schématique montrant l'utilisation de la clé pour le déblocage ou blocage de l'écrou d'une roue. Figure 1 is a schematic view showing the use of the key to unlock or lock the nut of a wheel.

La figure 2 est une vue semblable à la figureimontrtnt l'utilisation de la clé pour le serrage ou desserrage de l'éçrou. Figure 2 is a view similar to the figureimontrtnt the use of the key for tightening or loosening the nut.

La figure 3 est une vue en coupe partielle de la cle. Figure 3 is a partial sectional view of the key.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative en se référant aux exemples de réalisation des figures du dessin. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner with reference to the exemplary embodiments of the figures in the drawing.

La clé selon l'invention présente un corps (1) formant bras de levier dont une partie (la) convenablement coudée et centrée pour faire office de vilebrequin. L'une des extrémités du bras de levier est agencée pour recevoir une tête de cliquet réversible (2) conformée en (2a), d'une manière connue, pour la fixation démontable d'une douille (3) avec des empreintes internes hexagonales correspondant au dimensionnement de chaque écrou (E) de la roue. The key according to the invention has a body (1) forming a lever arm, a part (la) of which is bent and centered to act as a crankshaft. One end of the lever arm is arranged to receive a reversible pawl head (2) shaped in (2a), in a known manner, for the removable fixing of a socket (3) with corresponding hexagonal internal impressions the dimensioning of each nut (E) of the wheel.

La douille (3) est disposée angulairement par rapport au levier (1) dans un plan très sensiblement perpendiculaire. The sleeve (3) is arranged angularly relative to the lever (1) in a very substantially perpendicular plane.

D'une manière préférée, le levier (1) se raccorde à la partie recevant la tête de cliquet, en formant avec l'axe de la douille, un angle (cet) supérieur à 90 degrés afin de dégager ledit levier du plan défini par l'aile du véhicule.Preferably, the lever (1) is connected to the part receiving the ratchet head, forming with the axis of the socket, an angle (ce) greater than 90 degrees in order to disengage said lever from the plane defined by the wing of the vehicle.

A l'autre extrémité, le levier (1) reçoit d'une manière coaxiale, une autre douille à empreintes (4) identique à la douille (3). Comme précédemment, la douille (4) est engagée sur un nez (4a) en y étant maintenue par une bille escamotable rappelée par ressort. Les deux douilles (3) et (4) sont donc disposées dans des plans très sensiblement perpendiculaires (figure 3). At the other end, the lever (1) receives in a coaxial manner, another fingerprint socket (4) identical to the socket (3). As before, the sleeve (4) is engaged on a nose (4a) while being held there by a retractable ball returned by spring. The two sockets (3) and (4) are therefore arranged in very substantially perpendicular planes (Figure 3).

Le fonctionnement est très simple. Pour le déblocage (ou blocage) d'un écrou, on positionne la douille (3) et on agit angulairement sur le levier (1) pour commander la tête à cliquet (2) qui est indexée en position selon que l'on exerce une action de blocage ou déblocage (figure 1). Pour desserrer complètement l'écrou, on positionne la clé du côté de la douille (4) et on agit en rotation sur la partie (la) qui fait office de vilebrequin (figure 2).  The operation is very simple. To unblock (or lock) a nut, position the bushing (3) and act angularly on the lever (1) to control the ratchet head (2) which is indexed in position depending on whether one exercises a blocking or unblocking action (figure 1). To loosen the nut completely, the key is positioned on the side of the socket (4) and the part (la) which acts as the crankshaft is rotated (Figure 2).

La tête du cliquet réversible (2) est de tout type connv-eet appropriée notamment du type de celle présentant un moyen de repérage pour indiquer que l'on est indexé en position de serrage ou de desserrage. The head of the reversible pawl (2) is of any connv-eet type suitable in particular of the type of that having a locating means for indicating that one is indexed in the tightening or loosening position.

La section du corps (1) peut être pleine ou creuse. De même, la longueur du bras de levier -ainsi formé est convenablement déterminée afin de ne pas exercer un effort de serrage trop important. The body section (1) can be full or hollow. Similarly, the length of the lever arm thus formed is suitably determined so as not to exert too great a clamping force.

Les différents agencements que présentent les extrémités du corps de la clé pour la fixation d'une manière démontable des douilles, ne sont pas décrits en détail, comme parfaitement connus pour l'homme de métier. The various arrangements which the ends of the body of the key have for the detachably fixing of the sockets are not described in detail, as perfectly known to those skilled in the art.

Les avantages ressortent bien de la description, en particulier on souligne - La facilité d'utilisation - L'effort de serrage (ou de desserrage) à appliquer-résultant de la longueur du bras de levier, est très faible - Le caractère réversible de la clé.  The advantages emerge clearly from the description, in particular it is emphasized - The ease of use - The tightening (or loosening) force to be applied-resulting from the length of the lever arm, is very low - The reversible nature of the key.
