Abstract

When the two handles are gripped by the hand, the working jaws at one end are separated and the working jaws at the other end are brought together.

Description

Pince à double action pour le montage et le démontage des circlips intérieurs et extérieurs. Double action pliers for mounting and dismounting internal and external circlips.
L'invention concerne une pince à double action pour le montage et le démontage des circlips. Il en résulte que ces pinces peuvent s'appliquer à la fois à des circlips intérieurs et des circlips extérieurs. Les circlips sont très difficiles à retirer et à monter, de sorte que ces opérations sont pratiquement impossibles à réaliser sans outillages spéciaux. Afin qu'un utilisateur puisse monter et démonter les deux sortes de circlips, il est amené à utiliser deux pinces spéciales différentes. Une pince est utilisée pour les circlips intérieurs c'est-à-dire qu'elle ressert ceux-ci. L'autre pince est utilisée pour les circlips extérieurs c'est-à-dire qu'elle écarte ceux-ci.The invention relates to a double action pliers for mounting and dismounting circlips. As a result, these pliers can be applied to both internal and external circlips. Circlips are very difficult to remove and assemble, so that these operations are practically impossible to carry out without special tools. So that a user can assemble and disassemble the two kinds of circlips, he has to use two different special pliers. A pliers is used for the inner circlips, that is to say that it tightens these. The other clamp is used for the external circlips, that is to say it spreads these.
Sur le marché, il existe des pinces qui assurent les deux fonctions ci-dessus.On the market, there are pliers which perform the above two functions.
Le principal inconvénient de ces pinces à circlips pour les deux fonctions est que leur utilisation dans l'une ou l'autre fonction oblige une manipulation et un réglage. L'utilisateur est parfois amené à changer l'ensemble des machoires de travail tout en gardant les poignées.The main drawback of these circlip pliers for the two functions is that their use in one or the other function requires manipulation and adjustment. The user is sometimes required to change all of the working jaws while keeping the handles.
Toutes ces pinces possèdent un coût de production élevé dû au complexe de leur confection. L'utilisation de ces pinces est souvent plus compliquée que celle des pinces à simple fonction. L'invention à pour but de pallier les inconvénients pré-cités et concerne à cet effet une pince à double action pour circlips caractérisée en ce que les deux poignées font fonction de ressort de rappel et que les machoires de travail sont situées aux deux extrémités des poignées. En serrant les deux poignées ressorts qui se croisent en deux points d'articulation, on provoque à une extrémité l'ouverture des mâchoires pour les circlips extérieurs et à l'autre extrémité la fermeture des machoires pour les circlips intérieurs.All these pliers have a high production cost due to the complex of their manufacture. The use of these pliers is often more complicated than that of the single-function pliers. The invention aims to overcome the aforementioned drawbacks and for this purpose relates to a double action pliers for circlips characterized in that the two handles act as return spring and that the working jaws are located at the two ends of the handles. By tightening the two spring handles which cross at two points of articulation, one causes at one end the opening of the jaws for the external circlips and at the other end the closing of the jaws for the internal circlips.
D'autres caractéristiques de l'invention apparaîtront au cours de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés sur lsquels : - la Fig. 1 est une vue en plan de la pince à double action suivant une forme de réalisationOther characteristics of the invention will appear during the description which follows, given solely by way of example and made with reference to the accompanying drawings in which: - FIG. 1 is a plan view of the double action pliers according to one embodiment
- la Fig. 2 est une vue en plan de la pince à double action suivant une autre forme de réalisation Suivant l'exemple de réalisation représenté sur la Fig. 1, la pince à double action conforme à l'invention comprend deux poignées 1 et 2 identiques caractérisées en ce qu'elles sont flexibles et reviennent à leur position initiale dès l'instant où on relache la pression. Les quarre machoires de travail 3,4 etz 5,6 sont aux deux extremités de chaque pciqnée. La poignée et ses deux machoires sont d'un coût de fabrication peu élevé ; elle provient d'une tôle d'acier découpée qu'il suffit de torsader à 90° sur la longueur utilisée par la main. La poignée 1 avec ses mâchoires 3 et 4 et la poignée 2 avec ses machoires 5 et 6 sont assemblées par l'intermédiaire de deux axes rivetés 7 et 8 à chaque extrémité.- Fig. 2 is a plan view of the double action gripper according to another embodiment. According to the embodiment shown in FIG. 1, the double action pliers according to the invention comprises two identical handles 1 and 2 characterized in that they are flexible and return to their initial position from the moment the pressure is released. The four working jaws 3.4 and 5.6 are at the two ends of each part. The handle and its two jaws are of low manufacturing cost; it comes from a cut sheet of steel that can be twisted 90 ° over the length used by the hand. The handle 1 with its jaws 3 and 4 and the handle 2 with its jaws 5 and 6 are assembled by means of two riveted pins 7 and 8 at each end.
En pressant l ' une contre l'autre les poignées 1 et 2, on écarte les machoires 4 et 6 puis on resserre les machoires 3 et 5. On obtient les deux fonctions nécessaires pour ouvrir les circlips extérieurs et fermer les circlips intérieurs.By pressing the handles 1 and 2 against each other, we move aside the jaws 4 and 6 then we tighten the jaws 3 and 5. We obtain the two functions necessary to open the external circlips and close the internal circlips.
Suivant un autre exemple de réalisation représenté sur la Fig. 2, la pince à double action conforme à l'invention comprend deux poignées 9 et 10 identiques caractériséessèn ce qu'elles sont en matière synthétique, genre plastique souple réunissant les caractéristiques d'une lame ressort.According to another exemplary embodiment shown in FIG. 2, the double action pliers according to the invention comprises two identical handles 9 and 10 characterized in that they are made of synthetic material, of the flexible plastic type combining the characteristics of a leaf spring.
Les machoires de travail 11, 12 et 13, 14 sont découpées séparément. Il suffit au montage d'assembler les machoires 11, 12 avec la poignée 9 qui sera moulée et les machoires 13, 14 avec la poignée 10 qui sera moulée.The working jaws 11, 12 and 13, 14 are cut separately. It suffices during assembly to assemble the jaws 11, 12 with the handle 9 which will be molded and the jaws 13, 14 with the handle 10 which will be molded.
Les deux poignées 9 et 10 comportant leurs machoires respectives 11, 12 et 13, 14 sont assembléesThe two handles 9 and 10 comprising their respective jaws 11, 12 and 13, 14 are assembled
' Par l'intermédiaire de deux axes rivet 15 et 16 aux deux extrémités.'' Via two rivet pins 15 and 16 at both ends.
Suivant une: autre sorte d'assemblage, les machoires 11, 12 peuvent faire partie du moule quiformera la poignée 9 ; de même que les machoires 13, 14 avec la poignée 10.According to one: another kind of assembly, the jaws 11, 12 can be part of the mold which will form the handle 9; as well as the jaws 13, 14 with the handle 10.
Suivant une autre forme de fabrication qui ne change en rien les caracteristiques de la pince à double action, une lame d'acier faisant fonction de ressort peut-être moulée à l'intérieur des poignées 9 et 10.According to another form of manufacture which does not in any way change the characteristics of the double action pliers, a steel blade acting as a spring may be molded inside the handles 9 and 10.
La pince à double action selon l'invention peut être fabriquée sous différentes longueurs de façon a pouvoir monter et démonter plusieurs diamètres de circlips.The double action pliers according to the invention can be manufactured in different lengths so as to be able to mount and dismount several diameters of circlips.
La pince à double action selon l'invention peut comporter des machoires de travail recourbées suivant un angle déterminé afin de mieux accéder aux circlips pour leur montage et démonrage. The double action pliers according to the invention may include working jaws bent at a determined angle in order to better access the circlips for their mounting and dismounting.
