Abstract

The subject of the invention relates to the technical field of hand tools, more particularly for tightening wrenches. This wrench is noteworthy in that it comprises a body 1 forming a lever arm to act as a crankshaft and arranged at one of its ends so as to receive a socket with internal recesses, characterised in that the other end 1c is extended at the end at an angle relative to the longitudinal axis XX of the wrench and being arranged so as to receive a socket 3 with internal recesses 3a identical to those of the preceding socket.

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, topèrent au moyens 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 the vehicle wheels, top by means of crankshafts which originally fitted 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 de revient relativement élevé. Quant aux clés à cliquets, si elles sont relativement bien adaptées pour effectuer le déblocage initial de l'écrou, elles 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 of a relatively high cost price. 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 but recherché selon l'invention était de proposer une solution simple et peu coûteuse permettant d'assurer sans effort le déblocage initial de l'écrou et son desserrage complet et inversement. The aim sought after according to the invention was to propose a simple and inexpensive solution making it possible to effortlessly ensure the initial release of the nut and its complete loosening and vice versa.

Selon une première caractéristique, la clé selon llin- vention est remarquable en ce qu'elle comprend un corps formant bras de levier pour faire office de vilebrequin et agencé à une de ses extrémités pour recevoir une douille à empreintes internes, caractérisée en ce que l'autre extrémité se prolonge en bout angulairement par rapport à l'axe longitudinal XX de la clé et étant agencée pour recevoir une douille à empreintes internes identiques à celle de la douille précédente. According to a first characteristic, the key according to the invention is remarkable in that it comprises a body forming a lever arm to act as a crankshaft and arranged at one of its ends to receive a socket with internal impressions, characterized in that the 'other end extends at an angular end relative to the longitudinal axis XX of the key and being arranged to receive a socket with internal fingerprints identical to that of the previous socket.

Pour fixer l'objet de-linvention d'une manière non limitative illustrée aux figures du dessin où
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.To fix the object of the invention in a nonlimiting manner illustrated in the figures of the drawing where
Figure 1 is a schematic view showing the use of the key for unlocking or blocking the nut of a wheel.

La figure 2 est une vue semblable à la figure 1 montrant l'utilisation de la clé pour le serrage ou desserrage de l'écrou. Figure 2 is a view similar to Figure 1 showing the use of the wrench to tighten or loosen the nut.

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

La clé présente un corps (1) formant bras de levier est est dont une partie (la)/convenablement coudée et centrée pour faire office de villebrequin . L'une des extrémités (lb) reçoit de manière coaxiale directenent ou d'une manière rapportée une douille (2) à empreintes internes ou autres (2a) correspondant au dimensionnement de chaque écrou (E) de la roue. The key has a body (1) forming a lever arm and is including a part (la) / suitably bent and centered to act as a crankshaft. One of the ends (lb) receives directly or in a coaxial manner a socket (2) with internal or other imprints (2a) corresponding to the dimensioning of each nut (E) of the wheel.

Selon l'invention, l'autre extrémité (lc) se prolonge en bout angulairement par rapport à l'axe longitudinal XX de la clé, selon un angle obtu. Ladite extrémité est agencée pour recevoir directement ou d'une manière rapportée une ouille (3) à empreintes internes hexagonales ou autres (3a) identiques à la douille précédente. Ainsi qu'il apparait au dessin l'axe longitudinal de la clé est déporté d'un angle > { par rapport au plan défini par l'aile du véhicule. Les deux douilles (2) t3) sont disposées dans des plans angulaires différents. According to the invention, the other end (lc) extends at an angular end relative to the longitudinal axis XX of the key, at an obtuse angle. Said end is arranged to receive directly or in a reported manner a lug (3) with internal hexagonal or other imprints (3a) identical to the previous socket. As it appears in the drawing, the longitudinal axis of the key is offset by an angle> {relative to the plane defined by the wing of the vehicle. The two sockets (2) t3) are arranged in different angular planes.

L'utilisation de cette clé est particulièrement avantageuse. Son coût de revient est très faible car elle n'exige aucun moyen particulier d'adaptation, son encombrement est très réduit. The use of this key is particularly advantageous. Its cost is very low because it requires no special means of adaptation, its size is very small.

Son utilisation est aisée. Pour le déblocage ou blocage d'un écrou, on positionne la douille (3) et on agit angulairement sur le levier (1) sans être gêné par le véhicule. Pour effectuer l'opération complémentaire de desserrage, on utilise la seconde douille de manière usuelle du vilebrequin. Its use is easy. For the release or blocking of a nut, the socket (3) is positioned and the lever (1) is angularly acted on without being hampered by the vehicle. To carry out the additional loosening operation, the second socket is used in the usual manner for the crankshaft.

L'invention ne se limite aucunement à celui de ses modes d'application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées ; elle en embrasse au contraire toutes les variantes.  The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
