Description

La présente invention a pour objet une pince constituée de deux bras flexibles reliés ente eux par une de leurs extrémités, c'est-à-dire une pince du type brucelles.The present invention relates to a clamp consisting of two flexible arms connected ente them by one of their ends, that is to say a tweezer type clamp.

On connaît, par exemple, des brucelles coupantes, c'est-à-dire des brucelles dont l'extrémité constitue une pince coupante, qui sont largement utilisées pour couper des fils métalliques, en particulier sur les circuits imprimés. Or la coupe d'un fil métallique, même très mince, exige une force relativement grande. Lorsque l'opération est répétée toute la journée, la main se fatigue beaucoup. D'autre part, il est plus facile de fermer les brucelles en les pinçant, entre le pouce et l'index, tout près de son extrémité coupante. En outre, notamment dans des circuits imprimés, les éléments montés sur le circuit imprimé empêche souvent de pincer les brucelles près de leurs extrémités cou­pantes et l'utilisateur est obligé de pincer les bru­celles en un point relativement éloigné des extrémités coupantes, c'est-à-dire en un point où la fermeture des brucelles exige une force beaucoup plus élevée et la fatigue se fait sentir beaucoup plus vite.Known tweezers are known, for example, tweezers, the end of which constitutes a cutting pliers, which are widely used for cutting metal wires, in particular on printed circuits. However, cutting a wire, even a very thin one, requires a relatively large force. When the operation is repeated all day, the hand gets very tired. On the other hand, it is easier to close the tweezers by pinching them, between the thumb and forefinger, very close to its cutting end. In addition, particularly in printed circuits, the elements mounted on the printed circuit often prevent pinching the tweezers near their cutting ends and the user is obliged to pinch the tweezers at a point relatively distant from the cutting ends, that is to say ie at a point where closing the tweezers requires a much higher force and fatigue is felt much faster.

La présente invention a pour but de faciliter l'utili­sation d'une pince du type ci-dessus, notamment de bru­celles coupantes, par des moyens aussi simples que possible.The present invention aims to facilitate the use of pliers of the above type, in particular tweezers, by means as simple as possible.

La pince selon l'invention est caractérisée par le fait qu'elle est munie d'un levier auxiliaire d'actionnement amovible constitué d'une pièce coudée dont une partie est en forme de boucle entourant la pince, des moyens de positionnement étant prévus pour positionner le levier auxiliaire en un point intermédiaire de la pince.The clamp according to the invention is characterized in that it is provided with a removable auxiliary actuating lever consisting of a bent piece, a part of which is in the form of a loop surrounding the clamp, positioning means being provided for position the auxiliary lever at an intermediate point on the clamp.

Selon une forme d'exécution préférée de l'invention, le levier auxiliaire est constitué d'une plaquette coudée dont la boucle rectangulaire est munie d'un ergot s'en­gageant dans un trou de la pince pour son position­nement. Un trou de positionnement est prévu sur les deux branches de la pince, de telle sorte que le levier auxiliaire peut être placé d'un côté ou de l'autre de la pince, notamment pour permettre un actionnement du levier auxiliaire par l'index aussi bien pour un droitier que pour un gaucher ou pour permettre un actionnement soit par l'index soit par le pouce.According to a preferred embodiment of the invention, the auxiliary lever consists of a bent plate whose rectangular loop is provided with a lug engaging in a hole of the clamp for its positioning. A positioning hole is provided on the two arms of the clamp, so that the auxiliary lever can be placed on one side or the other of the clamp, in particular to allow actuation of the auxiliary lever also by the index finger. as well for a right-handed person as for a left-handed person or to allow actuation either by the index finger or by the thumb.

La force obtenue au moyen du levier auxiliaire permet de réaliser des pinces du type brucelles pour d'autres usages, par exemple des pinces à plier munies d'un profil, des pinces à redresser le fil métallique, des pinces à former. Les pinces obtenues sont légères et bon marché. La pince pourrait présenter deux paires de becs, l'une pour couper et l'autre pour plier, par exemple.The force obtained by means of the auxiliary lever makes it possible to produce tweezers of the tweezer type for other uses, for example bending pliers provided with a profile, pliers to straighten the metal wire, pliers to be formed. The pliers obtained are light and inexpensive. The pliers could have two pairs of beaks, one for cutting and the other for bending, for example.

Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'invention.

  • La figure 1 représente des brucelles coupantes ouver­tes, au repos.
  • La figure 2 est une vue des mêmes brucelles fermées, c'est-à-dire actionnées.
The accompanying drawing shows, by way of example, an embodiment of the invention.
  • Figure 1 shows open cutting tweezers, at rest.
  • Figure 2 is a view of the same closed tweezers, that is to say actuated.

Les brucelles coupantes représentées, de forme connue, présentent deux bras 1 et 2 dont les extrémités sont muni es de mâchoires coupantes 3 et 4. Sur les brucelles est monté un levier auxiliaire 5 constitué d'une pla­quette coudée présentant un bras d'actionnement 6 et une boucle rectangulaire 7 dont la longueur est telle que les branches 1 et 2 des brucelles sont légèrement sous tension, cette tension maintenant la boucle sur les brucelles. La boucle 7 est en outre munie d'un ergot 8 dirigé vers l'intérieur de la boucle et engagé dans un trou latéral 9 de l'une des branches des bru­celles, la branche 2 pour la position du levier auxi­liaire représenté en trait plein. Le levier auxiliaire 5 est ainsi positionné sur les brucelles en un point intermédiaire entre ses extrémités. L'autre branche 1 des brucelles est également munie d'un trou 10 permet­tant de monter le levier auxiliaire 5 sur les brucelles de telle sorte que son bras d'actionnement 6 soit situé de l'autre côté des brucelles, à la position 6′, son ergot 8 étant alors engagé dans le trou 10.The cutting tweezers shown, of known shape, have two arms 1 and 2, the ends of which are provided with cutting jaws 3 and 4. On the tweezers is mounted an auxiliary lever 5 consisting of a bent plate having an actuating arm 6 and a rectangular loop 7 whose length is such that the branches 1 and 2 of the tweezers are slightly under tension, this tension maintaining the loop on the tweezers. The loop 7 is further provided with a lug 8 directed towards the inside of the loop and engaged in a lateral hole 9 in one of the branches of the tweezers, the branch 2 for the position of the auxiliary lever shown in solid lines. The auxiliary lever 5 is thus positioned on the tweezers at an intermediate point between its ends. The other branch 1 of the tweezers is also provided with a hole 10 allowing the auxiliary lever 5 to be mounted on the tweezers so that its actuating arm 6 is located on the other side of the tweezers, in position 6 ′ , its lug 8 then being engaged in the hole 10.

Lorsqu'un utilisateur droitier saisit les brucelles en appuyant avec son pouce sur le bras du levier 6, le côté intérieur de la boucle 7 s'appuye sur la branche 2 en formant le point d'appui du levier, le côté opposé 7a de la boucle venant pousser la branche 1 des bru­celles. On constate qu'avec un bras de levier 6 relati­vement court, le serrage des brucelles devient très facile. Il est en outre possible de tenir les brucelles très en arrière des mâchoires coupantes, se qui faci­lite grandement l'accès aux fils a couper. Il est pos­sible de couper des fils d'un diamètre relativement grand, qui seraient très difficiles à couper avec des brucelles coupantes sans levier auxiliaire.When a right-handed user grasps the tweezers by pressing with his thumb on the arm of the lever 6, the inner side of the loop 7 is supported on the branch 2 by forming the fulcrum of the lever, the opposite side 7a of the loop pushing branch 1 of tweezers. It can be seen that with a relatively short lever arm 6, the tightening of the tweezers becomes very easy. It is also possible to hold the tweezers far behind the cutting jaws, which greatly facilitates access to the wires to be cut. It is possible to cut wires with a relatively large diameter, which would be very difficult to cut with tweezers without an auxiliary lever.

Le levier auxiliaire représenté en trait plein peut être soit actionné par le pouce par un droitier, soit actionné par l'index par un gaucher et inversement pour la position 6′ représentée en trait mixte. Les brucel­les coupantes selon l' invention présentent donc une grande souplesse d'utilisation.The auxiliary lever shown in solid line can be either actuated by the thumb by a right-handed person, or actuated by the index finger by a left-handed person and vice versa for position 6 ′ represented in phantom. The cutting tweezers according to the invention therefore have great flexibility of use.

Les brucelles coupantes sont susceptibles de variantes d'exécution. En particulier, la boucle 7 pourrait être d'une autre forme qu'une forme rectangulaire, par exem­ple ronde, ovale ou hexagonale. Au lieu d'un ergot et d'un trou, les moyens de positionnement pourraient être réalisé d'une autre manière, par exemple par deux bos­sages prévus sur la face extérieure des branches, bos­sages entre lesquels viendrait s'engager la boucle. L'ergot 8 pourrait être prévu à l'autre extrémité de la boucle c'est-à-dire, pour la position représentée en trait plein à la figure 1, dans le trou 10 l'effet du levier serait pratiquement le même.Cutting tweezers are subject to variant execution. In particular, the loop 7 could be of another shape than a rectangular shape, for example round, oval or hexagonal. Instead of a lug and a hole, the positioning means could be produced in another way, for example by two bosses provided on the outer face of the branches, bosses between which the loop would engage. The lug 8 could be provided at the other end of the loop, that is to say, for the position shown in solid lines in FIG. 1, in the hole 10 the effect of the lever would be practically the same.
