Description

Pince d'etabli La prdsente invention a pour objet une pince d'6tabli, comprenant un bäti portant deux mächoires dont l'une au moins, mobile et articul6e sur ledit bäti, est d6plagable en rotation par un levier, pour 1e serrage des mächoires, caract6risee par un Organe basculant, articu16 sur 1e bäti et dispos6 entre la mächoire mobile et ledit levier, et dont un bras est articuld, de fagon coulissante, sur 1e levier alors que Fautre commande 1e serrage de la mächoire, par des moyens maintenant en contact la mächoire et 1'or- gane basculant et par une but6e bloquant angu laire- ment 1e levier lorsque ledit Organe basculant est amen6 en une position angulaire dans laquelle il s'arc-boute ä la mächoire mobile, pour la verrouil- ler en position serrse. The subject of the present invention is a workbench clamp, comprising a frame carrying two jaws, at least one of which, movable and articulated on said frame, is displaceable in rotation by a lever, for clamping the jaws, characterized by a tilting member, articulated on the first frame and arranged between the mobile jaw and the said lever, and of which one arm is articulated, in a sliding fashion, on the first lever while the other controls the first tightening of the jaw, by means maintaining in contact the jaw and the tilting member and by a stop blocking the lever angularly when the said tilting member is brought into an angular position in which it butts against the movable jaw, to lock it in position. tighten.

Le dessin annex6 reprdsente, ä titre d'exemple, une forme d'execution de Fobjet de la presente In- vention. The attached drawing shows, by way of example, one embodiment of the object of the present invention.

La fig. 1 en est une 616vation de cöte. fig. 1 is a side elevation.

La fig. 2 en est une vue ä plus Brande schelle, avee arrachement partiel et Jans une position de travail et la fig. 3 une vue semblable ä la fig. 2 dans une autre position. fig. 2 is a view with more Brande schelle, with partial cutaway and Jans a working position and FIG. 3 a view similar to FIG. 2 in another position.

La pince reprdsentde au dessin comprend un bäti 1, portant deux mächoires 2 et 3 et un levier de commande 4, se prolongeant par une tige 5 sur laquelle est fix6 un support 6 destine ä la fixation de la pince sur stau non reprdsent6; la mächoire 2 est fixe alors que la mächoire 3 peut etre d6placee par rapport ä la premiere pour permettre de serrer des pieces de dimensions diff6rentes. L'6cartement des mächoires peut eire reg16 au moyen dune molette 7 en prise avec une tige filet6e 8 solidaire de la mä- choire 3. 9 est un 6erou permettant de bioquer la tige 7 dans une position axiale ddterminee. La mächoire 3 est articulde en 10 sur un cou- lisseau 11 associd ä la tige filetde 8 et susceptible de se mouvoir ä Fintdrieur dune fente 12 pratiqude dann 1e bäti 1 et s'stendant parallelement ä la tige 8 perpendiculairement au plan de la surface de ser- rage de 1a mächoire 2. The clamp shown in the drawing comprises a frame 1, carrying two jaws 2 and 3 and a control lever 4, extending by a rod 5 on which is fixed a support 6 intended for fixing the clamp on a stand, not shown; the jaw 2 is fixed while the jaw 3 can be moved relative to the first to allow workpieces of different sizes to be clamped. The spacing of the jaws can be adjusted by means of a wheel 7 in engagement with a threaded rod 8 integral with the jaw 3. 9 is a 6eror allowing the rod 7 to be locked in a determined axial position. The jaw 3 is articulated at 10 on a slider 11 associated with the threaded rod 8 and able to move inside a slot 12 made in the frame 1 and extending parallel to the rod 8 perpendicularly to the plane of the surface of the jaw clamping 2.

La mächoire 3, qui est de forme sensiblement triangulaire, est en outre soumise ä Faction d'un ressort 13 tendu entre un t6ton 3a solidaire de cette mächoire et un axe 14a fix6 au bäti 1 et autour du- quel peut basculer un levier 14. L'une des extr6mitds de ce levier porte un galet 14b par lequel ce levier est constamment en contact avec la mächoire sous 1'action du ressort 13. Lautre extrdmit6 du levier 14 pr6sente une RTI ID="0001.0270" WI="7" HE="4" LX="1812" LY="1848"> gou- pille 14c engag6e dans une fente oblongue 4a d6 coup6e dans 1e levier 4; ce levier est pivotd en 4b sur 1e bäti 1. Une but6e 15 solidaire du bäti 1 bloque angulairement 1e levier 4, lors de son dd- placement dans 1e sens f, lorsque Faxe 14a et 1e point de contact du galet 14b avec la mächoire 3 sont en alignement perpendiculairement ä la surface de contact de ce galet avec cette mächoire. Dans cette position, qui correspond ä la position de ser- rage des mächoires 2 et 3, 1e levier 14 s'arc-boute en effet ä cette mächoire et en empeche tout d6- placement dans 1e sens antihoraire. Lorsque, au contraire, 1e levier 4 est dloign6 de la but6e 15, par d6placement dans 1e sens contraire ä f, 1e levier 14 est bascu1d dans la position reprd- sentee en fig. 3 autour de son axe 14a et ne s'arc- boute plus ä la mächoire 3, permettant ainsi ä cette mächoire de se d6placer ldgerement dans 1e sens antihoraire sous Faction du ressort 13. Dans une variante d'execution, non representee, la mächoire 3 presente une fente oblongue, s'eten- dant dans 1e prolongement de la fente 12 du bäti 1, et 1'extremite drohe du levier 14 est en Prise avec cette mächoire par engagement dune goupille dans la fente; 1'ouverture de la mächoire 3 est alors effec- tu6e directement par 1e levier 14 Tors de son bas- culement dans une Position correspondante ä celle de la fig. 3. Jaw 3, which is substantially triangular in shape, is also subjected to the action of a spring 13 stretched between a pin 3a integral with this jaw and a pin 14a fixed to frame 1 and around which a lever 14 can pivot. One of the ends of this lever carries a roller 14b by which this lever is constantly in contact with the jaw under the action of the spring 13. The other end of the lever 14 has an RTI ID="0001.0270" WI="7" HE ="4" LX="1812" LY="1848"> pin 14c engaged in an oblong slot 4a d6 cut in the lever 4; this lever is pivoted at 4b on the first frame 1. A but6e 15 secured to the frame 1 angularly blocks the first lever 4, during its displacement in the first direction f, when the faxe 14a and the first point of contact of the roller 14b with the jaw 3 are in alignment perpendicular to the contact surface of this roller with this jaw. In this position, which corresponds to the clamping position of the jaws 2 and 3, the lever 14 in fact braces this jaw and prevents any movement in the counterclockwise direction. When, on the contrary, the lever 4 is moved away from the stop 15, by displacement in the opposite direction to f, the lever 14 is tilted into the position represented in FIG. 3 around its axis 14a and no longer butts against the jaw 3, thus allowing this jaw to move slightly in the first counterclockwise direction under the action of the spring 13. In a variant embodiment, not shown, the jaw 3 has an oblong slot, extending in the extension of slot 12 of frame 1, and the right end of lever 14 is in engagement with this jaw by engagement of a pin in the slot; the opening of the jaw 3 is then effected directly by the lever 14 when it tilts into a position corresponding to that of FIG. 3.

Claims

CLAIM Bench clamp, comprising a frame carrying two jaws fitted at least, movable and articulated on said frame, can be moved in rotation by a lever, for the first tightening of these jaws, characterized by a tilting member, articulated on the first built and arranged between the movable jaw and said lever, and one arm of which is articulated, in a sliding fashion, on the lever while the other controls the clamping of the jaw, by means now in contact with the jaw and the rocking member and by a stop blocking the lever angularly when said rocking member is brought into an angular position in which it butts against the mobile jaw, to lock it in the clamped position. SUB-CLAIMS 1. Pliers according to claim, characterized in that the said means are constituted by at least one elastic member stretched between an integral element of the frame and the mobile jaw.

2. Pliers according to claim and sub-claim 1, characterized in that said tilting member is in contact with a face of the mobile jaw, extending substantially in a plane perpendicular to the plane of this jaw, by a rolling aallet.

3. Pliers according to claim, characterized in that said jaw has a slot extending substantially parallel to the clamping direction and that said tilting member is articulated in a sliding fashion in this slot.
