Abstract

The vice-grip wrench (mole grip) which is the subject of the invention comprises a first fixed jaw 2 secured to a main lever 1 and a second movable jaw 6 capable of oscillating in oblong slots 4 of the main lever under the action of a knee joint 9, 10 forming a manoeuvring lever for locking the said jaws on the object to be clamped after reaching a neutral point. The movable jaw 6 comprises a pin 5 whose ends are oval and whose largest diameter D is slightly greater than the width L of the oblong slots so that, when the movable jaw 6 oscillates, the two poles on each end of its pin 5 become wedged against the edges of the oblong slot 4.

Description

Pince-étau à mâchoires autoréglables. Self-adjusting jaw pliers.

La présente invention concerne une pince-étau du genre comprenant une première mâchoire fixe solidaire d'un levier principal et une seconde mâchoire susceptible d'osciller sur le levier principal et reliée, par une genouillère formant levier de manoeuvre, au levier principal pour ouvrir ladite mâchoire mobile ou la bloquer en position de fermeture sur l'objet à serrer par verrouillage de la genouillère après franchissement d'un point mort. The present invention relates to a vise-grip of the kind comprising a first fixed jaw secured to a main lever and a second jaw capable of oscillating on the main lever and connected, by a toggle forming an operating lever, to the main lever to open said lever. movable jaw or lock it in the closed position on the object to be tightened by locking the toggle joint after crossing a neutral position.

Dans les pinces connues de ce type, le réglage de l'écartement de la seconde mâchoire mobile est réalisé au moyen d'une crémaillère pratiquée dans les deux joues du levier principal. In known clamps of this type, the spacing of the second movable jaw is adjusted by means of a rack made in the two cheeks of the main lever.

L'axe d'oscillation de la mâchoire mobile est, en effet, susceptible d'être retenu dans l'une des encoches de la crémaillère.The axis of oscillation of the movable jaw is, in fact, capable of being retained in one of the notches of the rack.

Cette opération de réglage préalable de l'écartement des mâchoires, nécessite une manoeuvre de l'axe d'oscillation de la mâchoire mobile pour l'amener au contact de la pièce à serrer et, selon son épaisseur, l'utilisateur choisit l'encoche de la crémaillère appropriée.This prior adjustment operation of the jaw spacing requires an operation of the axis of oscillation of the movable jaw to bring it into contact with the part to be clamped and, depending on its thickness, the user chooses the notch of the appropriate rack.

Au contraire avec la pince-étau objet de l'invention, l'utilisateur n'a plus besoin d'opérer le réglage préalable des mâchoires contre l'objet à serrer puisque celui-ci a lieu automatiquement. On the contrary with the vise grip object of the invention, the user no longer needs to make the prior adjustment of the jaws against the object to be clamped since it takes place automatically.

Dans ce but, la mâchoire mobile, dont l'axe d'oscillation est guidée dans une lumière oblongue du levier principal, comporte un moyen de blocage dudit axe quel que soit l'écartement de la mâchoire mobile par rapport à l'autre mâchoire fixe du levier principal. To this end, the movable jaw, the oscillation axis of which is guided in an oblong opening in the main lever, comprises means for blocking said axis whatever the distance between the movable jaw and the other fixed jaw of the main lever.

Suivant une première forme d'exécution de l'invention, le moyen de blocage de l'axe de la mâchoire, est constitué par l'axe lui-même qui est oval et dont le plus grand diamètre est légèrement supérieur à la largeur de la lumière oblongue dans laquelle il peut se déplacer, de sorte que quand la mâchoire mobile oscille les deux piles de son axe se coincent contre
les rives de la lumière oblongue, bloquant ladite mâchoire. According to a first embodiment of the invention, the means for locking the axis of the jaw, is constituted by the axis itself which is oval and whose largest diameter is slightly greater than the width of the oblong light in which it can move, so that when the movable jaw oscillates the two piles of its axis get stuck against
the banks of the oblong lumen, blocking said jaw.

Suivant une autre forme d'exécution de l'invention, le moyen de blocage de l'axe de la mâchoire mobile est constitué par une came que forme l'extrémité supérieure de ladite mâchoire et qui prend appui contre une paroi perpendiculaire accouplant les deux joues du levier principal, de sorte que le mouvement d'oscillation de ladite mâchoire provoque le coincement de la came contre ladite paroi. According to another embodiment of the invention, the means for blocking the axis of the movable jaw consists of a cam which forms the upper end of said jaw and which bears against a perpendicular wall coupling the two cheeks of the main lever, so that the oscillating movement of said jaw causes the cam to jam against said wall.

Dre tout-e Façon, les détails de ces deux formes d'exécution de l'invention seront mieux compris par la description qui va suivre, se référant aux dessins annexés sur lesquels
La figure 1 est une vue en élévation d'une pince-étau selon l'invention, comportant un premier moyen de blocage de l'axe de la mâchoire mobile.Dre tout-e Façon, the details of these two embodiments of the invention will be better understood from the description which follows, referring to the appended drawings in which
Figure 1 is an elevational view of a vise grip according to the invention, comprising a first locking means of the axis of the movable jaw.

La figure 2 montre le détail à échelle agrandie de ce moyen de blocage. Figure 2 shows the detail on an enlarged scale of this locking means.

La figure 3 est une vue en élévation d'une pince-étau comportant un autre moyen de blocage de l'axe de la mâchoire mobile. Figure 3 is an elevational view of a vise grip having another locking means of the axis of the movable jaw.

La figure 4 montre le détail à échelle agrandie de ce moyen de blocage. Figure 4 shows the detail on an enlarged scale of this locking means.

La pince-étau représentée figures 1 et 3 comprend, à la manière connue, un levier principal 1 en forme de chape en U dont l'une des extrémités est équipée d'un mors 2 et qui constitue la mâchoire fixe de la pince. The vice grip shown in Figures 1 and 3 comprises, in known manner, a main lever 1 in the form of a U-shaped yoke, one end of which is equipped with a jaw 2 and which constitutes the fixed jaw of the clamp.

Dans la partie élargie 3 que forment les deux joues du levier 1 sont prévues deux lumières oblongues 4. Dans les deux lumières 4 en vis à vis, sont logées les extrémités d'un axe 5 emmanché serré à l'extrémité d'une deuxième mâchoire 6 dite mâchoire oscillante, affectant la forme d'un U dont l'une des branches est traversée par l'axe 5, tandis que l'autre branche constitue le second mors de la pince. In the enlarged part 3 formed by the two cheeks of the lever 1 are provided two oblong slots 4. In the two slots 4 facing each other, the ends of a pin 5 fitted tightly fitted at the end of a second jaw are housed 6 said oscillating jaw, affecting the shape of a U of which one of the branches is crossed by the axis 5, while the other branch constitutes the second jaw of the clamp.

La mâchoire mobile 6 comporte une oreille percée d'un trou pour la fixation de l'extrémité d'un ressort à boudin 7 par ailleurs amarré, par son autre extrémité, à une goupille 8 du levier 1. The movable jaw 6 has an ear pierced with a hole for fixing the end of a coil spring 7 which is also moored, at its other end, to a pin 8 of the lever 1.

La mâchoire 6 est accouplée à un second levie 9 comportant une biellette 10 articulée, par un axe 11, audit levier et dont l'extrémité prend appui contre l'extrémité d'une vis de réglage 12 à tête moletée 13 prenant écrou dans la branche du levier 1. The jaw 6 is coupled to a second lever 9 comprising a link 10 articulated by an axis 11, to said lever and the end of which bears against the end of an adjustment screw 12 with knurled head 13 taking nut in the branch lever 1.

Dans le second levier 9 est articulé un levier auxiliaire 14 prenant appui contre le levier principal 1 pour permettre le déblocage de la genouillère constituée du levier 9 et de la biellette 10. In the second lever 9 is articulated an auxiliary lever 14 bearing against the main lever 1 to allow the release of the toggle joint constituted by the lever 9 and the link 10.

Comme l'illustre bien la figure 2, chaque extrémité de l'axe 5 est ovale.Elle-comporte deux plats et son plus grand diamètre D est légèrement supérieur à la largeur L de la lumière 4 dans laquelle elle est engagée. As illustrated in Figure 2, each end of the axis 5 is oval. It has two plates and its largest diameter D is slightly greater than the width L of the light 4 in which it is engaged.

Grâce à ce système simple et pratique le réglage des mâchoires 2 et 6 est automatique autour de l'objet à serrer. Au fur et à mesure que l'utilisateur agit sur le levier 9 la mâchoire 6, en butée contre l'objet à serrer, oscille sur son axe 5 qui tend à se déplacer dans la lumière 4 tout en pivotant jusqu'à ce que les deux pâles dudit axe viennent se coincer contre les bords de la lumière 4 comme l'illustre bien la figure 2. L'axe 5 s'immobilise dans la lumière 4 mais autorise encore le léger mouvement oscillant de la mâchoire 6 sous l'action de la genouillère 9, 10 dont l'arqueboutement provoque, à la manière connue, le blocage des mâchoires 2,6 de la pince. Thanks to this simple and practical system, the adjustment of the jaws 2 and 6 is automatic around the object to be clamped. As the user acts on the lever 9 the jaw 6, in abutment against the object to be clamped, oscillates on its axis 5 which tends to move in the lumen 4 while pivoting until the two blades of the said axis get stuck against the edges of the light 4 as well illustrated in FIG. 2. The axis 5 stops in the light 4 but still allows the slight oscillating movement of the jaw 6 under the action of the toggle joint 9, 10, the arching of which causes, in the known manner, the locking of the jaws 2.6 of the clamp.

Suivant les figure 3 et 4, un autre dispositif de blocage de la mâchoire 6 est envisagé. I1 s'agit d'une came 15- que forme l'extrémité de la mâchoire 6 et qui peut prendre appui contre une paroi 16 entretoisant les deux joues 3 du levier principal 1. L'axe 17, qui autorise l'oscillation de la mâchoire 6, est cylindrique et son diamètre est sensiblement identique à la largeur de la lumière 4. According to FIGS. 3 and 4, another device for blocking the jaw 6 is envisaged. I1 is a cam 15- that forms the end of the jaw 6 and which can bear against a wall 16 bracing the two cheeks 3 of the main lever 1. The axis 17, which allows the oscillation of the jaw 6, is cylindrical and its diameter is substantially identical to the width of the lumen 4.

Lorsque, sous l'action du levier 9, la mâchoire 6 serre l'objet contre l'autre mâchoire fixe 2, elle oscille autour de son axe 17 et sa came 15 s'appuie contre la paroi 16 et provoque le coincement dudit axe 17 dans la lumière, tout en autorisant le blocage, par la genouillère 9,10, des mâchoires 2,6 autour de l'objet à serrer.  When, under the action of the lever 9, the jaw 6 clamps the object against the other fixed jaw 2, it oscillates around its axis 17 and its cam 15 bears against the wall 16 and causes said axis 17 to jam in the light, while allowing the blocking, by the toggle 9.10, of the jaws 2.6 around the object to be clamped.
