Description

La présente invention concerne les étaux et se rapporte plus particulièrement aux étaux pour tables de travail ou établis du type professionnel ou bricoleur.The present invention relates to vices and relates more particularly to vices for work tables or workbenches of the professional or handyman type.

Les utilisateurs de matériel de ce type disposent généralement de peu de place pour installer leur outillage, de sorte qu'il leur est difficile de laisser à demeure sur une table ou même sur un établi de petites dimensions, un étau que rend alors une partie de la table inutilisable pour des travaux nécessitant une surface libre sur la table ou l'établi relativement importante.Users of equipment of this type generally have little space to install their tools, so that it is difficult for them to leave permanently on a table or even on a workbench of small dimensions, a vice which then makes part of the table cannot be used for work requiring a relatively large free surface on the table or workbench.

Par ailleurs, les étaux actuellement disponibles dans le commerce ne peuvent assurer un serrage que dans une seule direction alors qu'il est quelquefois intéressant de pouvoir immobiliser une pièce dans plusieurs directions correspondant à des opérations qu'il y a lieu d'effectuer sur cette pièce.Furthermore, the vises currently available on the market can only tighten in one direction, while it is sometimes advantageous to be able to immobilize a workpiece in several directions corresponding to operations that should be carried out on this. room.

On connaît déjà différents types de dispositifs de serrage pouvant être utilisés pour fixer un objet sur un plateau en prenant appui sur la surface inférieure de celui-ci, au voisinage de son bord, par exemple comme décrit au brevet US N° 4 176 830, mais ce dispositif, qui comprend un étrier en V articulé par une extrémité sur un organe d'appui et comportant à son extrémité opposée des moyens de serrage élastique ne peut être utilisé que comme une pince et non pas comme un étau.We already know different types of clamping devices that can be used to fix an object on a tray by resting on the lower surface of the latter, in the vicinity of its edge, for example as described in US Pat. No. 4,176,830, but this device, which comprises a V-shaped bracket articulated by one end on a support member and comprising at its opposite end elastic clamping means can only be used as a clamp and not as a vice.

Le brevet US N° 2 658 540 décrit un dispositif comprenant un élément coudé articulé par une extrémité sur un axe porté par un support et comportant à son extrémité opposée un manchon fileté dans lequel est disposée une vis portant à une extrémité un organe de serrage.US Patent No. 2,658,540 describes a device comprising a bent element articulated by one end on an axis carried by a support and comprising at its opposite end a threaded sleeve in which is disposed a screw carrying at one end a clamping member.

Ce dispositif est adapté pour serrer un objet sur une surface sur laquelle il est lui-même fixé.This device is suitable for clamping an object on a surface on which it is itself fixed.

L'invention vise à créer un étau qui, tout en étant d'une construction très simple, puisse être aisément monté et démonté et soit utilisable pour assurer des serrages de pièces dans plusieurs directions différentes et puisse laisser entièrement dégagée la surface de travail lorsqu'il est inutilisé.The invention aims to create a vice which, while being of a very simple construction, can be easily assembled and disassembled and can be used to ensure clamping of parts in several different directions and can leave the working surface entirely free when it is unused.

Elle a en conséquence pour objet une presse-étau destinée à être fixée sous un plateau de table ou d'établi, à proximité d'un bord dudit plateau, du type comportant un bâti, un étrier articulé sur ledit bâti par une de ses extrémités et portant à son extrémité opposée une vis de serrage pourvue d'une mâchoire, ledit bâti étant fixé à une semelle caractérisée en ce que la semelle est montée à coulissement dans un rail fixé sous ledit plateau, et en ce qu'elle comporte en outre des moyens de maintien dudit étrier dans des positions angulaires déterminées par rapport au plateau.It therefore relates to a vice press intended to be fixed under a table or bench top, near an edge of said tray, of the type comprising a frame, a stirrup articulated on said frame by one of its ends. and carrying at its opposite end a clamping screw provided with a jaw, said frame being fixed to a sole characterized in that the sole is slidably mounted in a rail fixed under said plate, and in that it further comprises means for holding said bracket in angular positions determined relative to the plate.

La presse-étau représentée à la fig. 1 comporte principalement un bâti 1 fixé sous un plateau 2 d'une table ou d'un établi par l'intermédiaire d'une semelle 3 engagée dans un rail 4 présentant une section en U à bords rabattus, disposé à proximité d'un bord du plateau 2 et fixé audit plateau par des moyens non représentés.The vice press shown in fig. 1 mainly comprises a frame 1 fixed under a tray 2 of a table or workbench by means of a sole 3 engaged in a rail 4 having a U-shaped section with folded edges, disposed near an edge of plate 2 and fixed to said plate by means not shown.

Le bâti 1 comporte deux flasques verticaux 5 de forme à peu près circulaire venus de matière avec la semelle 3, pourvus chacun d'un orifice central 6 dans lequel est engagé un axe 7 d'articulation d'un étrier 8 en forme de U, qui porte à son extrémité opposée un ensemble 9 de vis de serrage qui comporte la vis de serrage 10 proprement dite engagée dans un trou fileté ménagé dans l'étrier 8 et une tige de guidage 11 qui traverse un trou lisse également prévu dans l'étrier. La vis 10 comporte à l'une de ses extrémités une poignée d'actionnement 12 et à son extrémité opposée une mâchoire 13 qui est également portée par l'extrémité correspondante de la tige de guidage 11.The frame 1 comprises two vertical flanges 5 of roughly circular shape formed integrally with the sole 3, each provided with a central orifice 6 in which is engaged an axis 7 of articulation of a U-shaped bracket 8, which carries at its opposite end a set 9 of clamping screws which comprises the clamping screw 10 proper engaged in a threaded hole formed in the stirrup 8 and a guide rod 11 which passes through a smooth hole also provided in the stirrup . The screw 10 comprises at one of its ends an actuating handle 12 and at its opposite end a jaw 13 which is also carried by the corresponding end of the guide rod 11.

L'étrier 8 comporte à son extrémité par laquelle il est articulé sur le bâti 1, une saillie 14 destinée à coopérer avec des rainures 15 correspondantes ménagées sur l'un des flasques 5, disposés dans des positions angulaires déterminées pour définir des positions d'utilisation de la presse-étau. L'étrier 8 est rendu solidaire de l'axe 7 par une goupille 16 et l'axe 7 est sollicité vers le flasque 5 pourvu des rainures 15 par un ressort 17 monté dans l'orifice 6 du flasque 5 opposé et maintenu dans cet orifice par un cir- clips 18.The stirrup 8 comprises at its end by which it is articulated on the frame 1, a projection 14 intended to cooperate with corresponding grooves 15 formed on one of the flanges 5, arranged in determined angular positions to define positions of use of the vice. The stirrup 8 is made integral with the axis 7 by a pin 16 and the axis 7 is biased towards the flange 5 provided with the grooves 15 by a spring 17 mounted in the orifice 6 of the opposite flange 5 and held in this orifice by a circlip 18.

En se référant plus particulièrement à la fig. 1, on voit que l'étrier 8 se trouve, comme représenté en traits pleins maintenu en position horizontale, ce qui permet d'utiliser la presse-étau pour assurer le serrage en bout d'une pièce que l'on place en butée contre un taquet 19 prévu sur le plateau 2, ou directement sur le chant du plateau.With particular reference to FIG. 1, it can be seen that the stirrup 8 is, as shown in solid lines, maintained in a horizontal position, which makes it possible to use the vice press to ensure the clamping at the end of a part which is placed in abutment against a cleat 19 provided on the plate 2, or directly on the edge of the plate.

On voit également, comme représenté en traits mixtes, que l'étrier peut être placé en position verticale auquel cas, la presse-étau peut assurer un serrage d'une pièce simplement posée sur le plateau 2.It can also be seen, as shown in phantom, that the stirrup can be placed in a vertical position in which case, the vice press can ensure a clamping of a part simply placed on the plate 2.

Enfin, une vue partielle en traits mixtes de l'étrier 8 montre que celui-ci peut être placé en position effacée de manière à dégager complé- tement le plateau 2.Finally, a partial view in dashed lines of the stirrup 8 shows that it can be placed in the erased position so as to completely release the plate 2.

Dans chacune de ces trois positions représentées à la fig. 1, la saillie 14 de l'étrier 8 doopère avec une rainure 15 correspondante, l'étrier étant appliqué contre le flasque pourvu desdites rainures par le ressort 17.In each of these three positions shown in FIG. 1, the projection 14 of the stirrup 8 operates with a corresponding groove 15, the stirrup being applied against the flange provided with said grooves by the spring 17.

Le fait de monter le bâti 1 de la presse-étau suivant l'invention par l'intermédiaire d'une semelle 3 engagée à coulissement dans un rail 4, disposé sous le plateau d'une table ou d'un établi, permet de déplacer l'étau le long dudit rail dans toutes positions appropriées d'utilisation. Le rail permet en outre de recevoir deux ou plusieurs presse-étaux suivant l'invention lorsqu'il s'agit de maintenir une pièce d'une grande longueur.The fact of mounting the frame 1 of the vice press according to the invention by means of a sole 3 slidingly engaged in a rail 4, disposed under the table top or a workbench, makes it possible to move the vice along said rail in all appropriate positions of use. The rail also makes it possible to receive two or more clamps according to the invention when it is a question of holding a piece of great length.

Par ailleurs, il est possible d'envisager de disposer plusieurs rails à la périphérie du plateau 2 de manière à permettre l'utilisation de la presse-étau suivant l'invention sur plusieurs côtés du plateau.Furthermore, it is possible to envisage having several rails at the periphery of the plate 2 so as to allow the use of the vise clamp according to the invention on several sides of the plate.

Le rail peut être réalisé curviligne auquel cas, la semelle 3 doit présenter une forme lui permettant de coulisser dans les parties incurvées du rail4.The rail can be made curvilinear in which case, the sole 3 must have a shape allowing it to slide in the curved parts of the rail4.

La presse-étau représentée à la fig. 4 concerne comme celle de la fig. 1, un bâti 20 fixé sous un plateau 21 d'une table par l'intermédiaire d'une semelle 22 engagée dans un rail 23 présentant une section en U à bords rabattus, disposée à proximité d'un bord du plateau 21 et fixée audit plateau par des vis 24.The vice press shown in fig. 4 relates like that of FIG. 1, a frame 20 fixed under a plate 21 of a table by means of a sole 22 engaged in a rail 23 having a U-shaped section with folded edges, disposed near an edge of the plate 21 and fixed to said plate by screws 24.

Le bâti 20 comporte deux flasques verticaux 25 ayant à peu près la forme de demi-cercleset pourvus chacun d'un orifice central 26 dans lequel est engagé un axe 27 d'articulation d'un support oscillant 28 pour une tige 29 dont une extrémité 30 repliée à angle droit supporte un ensemble de mâchoire 31. Ainsi qu'on peut le voir à la fig. 5, le support oscillant 28 comporte une première douille 32 dans laquelle est engagé l'axe 27 d'articulation du support et une seconde douille 33 de direction perpendiculaire à la première, dans laquelle est engagée la tige 29 portant l'ensemble de mâchoire 31. Les deux douilles 32 et 33 sont reliées entre elles par une âme 34 pourvue d'un orifice 35 dans lequel est engagée une broche 36 d'immobilisation angulaire du support 28.The frame 20 comprises two vertical flanges 25 having roughly the shape of semicircles and each provided with a central orifice 26 in which is engaged an axis 27 of articulation of an oscillating support 28 for a rod 29, one end of which 30 folded at a right angle supports a jaw assembly 31. As can be seen in FIG. 5, the oscillating support 28 comprises a first socket 32 in which is engaged the axis 27 of articulation of the support and a second socket 33 of direction perpendicular to the first, in which is engaged the rod 29 carrying the jaw assembly 31 The two sockets 32 and 33 are interconnected by a core 34 provided with an orifice 35 in which is engaged a pin 36 for angular immobilization of the support 28.

La broche 36 est pourvue à une de ses extrémités d'une poignée 37 et elle est engagée dans des orifices d'indexation 38 régulièrement répartis à la périphérie des flasques 25. La broche 36 est en outre maintenue en place par un ressort 39 disposé entre l'âme 34 du support 28 et une rondelle 40 prenant appui contre l'un des flasques 25 du bâti 20; le ressort 39 et la rondelle 40 sont tous deux montés sur l'extrémité de la broche 36 opposée à la poignée 37.The pin 36 is provided at one of its ends with a handle 37 and it is engaged in indexing orifices 38 regularly distributed around the periphery of the flanges 25. The pin 36 is also held in place by a spring 39 disposed between the core 34 of the support 28 and a washer 40 bearing against one of the flanges 25 of the frame 20; the spring 39 and the washer 40 are both mounted on the end of the pin 36 opposite the handle 37.

Une vis 41 pourvue d'un bouton de manoeuvre 42 est destinée à assurer l'immobilisation de la tige 29 dans la douille 33.A screw 41 provided with an operating button 42 is intended to immobilize the rod 29 in the socket 33.

On voit qu'ainsi le support oscillant 28 constitue avec la tige 29 et son extrémité pliée à angle droit 30, un étrier dont la longueur peut être réglée en déplaçant axialement la tige 29 dans la douille 33.It can be seen that thus the oscillating support 28 constitutes with the rod 29 and its end bent at right angles 30, a stirrup the length of which can be adjusted by axially moving the rod 29 in the socket 33.

Un gousset de renforcement 43 est avantageusement soudé au niveau du coude reliant la tige 29 à son extrémité 30.A reinforcing gusset 43 is advantageously welded at the elbow connecting the rod 29 at its end 30.

L'ensemble de mâchoire 31 est constitué par un manchon fileté 44 soudé à l'extrémité 30 de la tige 29 et dans lequel est montée une vis de serrage 45. La vis 45 comporte à l'une de ses extrémités une poignée d'actionnement 46 et se termine à son extrémité opposée par une rotule 47 sur laquelle est articulée une mâchoire 48. Sur sa face opposée à celle se trouvant en regard du plateau 21, la mâchoire 48 porte un guide 49 d'immobilisation en rotation terminé à sa partie inférieure par une encoche 50 chevauchant la tige 29.The jaw assembly 31 is constituted by a threaded sleeve 44 welded to the end 30 of the rod 29 and in which a clamping screw 45 is mounted. The screw 45 comprises at one of its ends an actuating handle 46 and ends at its opposite end with a ball joint 47 on which a jaw 48 is articulated. On its face opposite to that which is opposite the plate 21, the jaw 48 carries a guide 49 for immobilization in rotation completed in its part lower by a notch 50 overlapping the rod 29.

Ainsi qu'on peut le voir à la fig. 7, la semelle 22 du bâti 20 est réunie aux flasques 25 par une portion 51 de forme octogonale dont la distance entre deux côtés parallèles est légèrement inférieure à l'écartement entre les bords rabattus du rail 23 fixé sous le plateau 21.As can be seen in fig. 7, the sole 22 of the frame 20 is joined to the flanges 25 by a portion 51 of octagonal shape whose distance between two parallel sides is slightly less than the spacing between the folded edges of the rail 23 fixed under the plate 21.

Par ailleurs, le rail 23 présente à l'une de ses extrémités, une portion 52 de changement d'orientation du bâti 20. Dans cette portion 52, les rebords rabattus du rail comportent des découpes 53 dans lesquelles sont placés des ressorts à lames 54 destinés à permettre la rotation de la partie 51 du bâti 20 tout en assurant son maintien dans la position angulaire choisie.Furthermore, the rail 23 has, at one of its ends, a portion 52 for changing the orientation of the frame 20. In this portion 52, the folded edges of the rail include cutouts 53 in which are placed leaf springs 54 intended to allow the rotation of the part 51 of the frame 20 while ensuring its maintenance in the chosen angular position.

Un tel agencement permet de choisir huit orientations différentes de la mâchoire 48 par rapport au plateau 21, ce qui augmente considérablement les possibilités de la presse-étau.Such an arrangement makes it possible to choose eight different orientations of the jaw 48 relative to the plate 21, which considerably increases the possibilities of the vice press.

La variante de presse-étau représentée à la fig. 8 differe de celle de la fig. 4 en ce que l'étrier porte-mâchoire de cette presse-étau est constitué par une tige coudée 55 dont une partie 56 pliée à angle droit, porte à son extrémité une douille 57 articulée sur un bâti non représenté analogue au bâti 20 de la fig. 4, et par un ensemble de mâchoire 58 fixé de façon réglable sur la portion rectiligne de la tige 55 au moyen d'un support 59.The variant of vice clamp shown in fig. 8 differs from that of FIG. 4 in that the jaw-holder stirrup of this vice-press is constituted by a bent rod 55 of which a part 56 bent at right angles, carries at its end a socket 57 articulated on a frame not shown similar to the frame 20 of the fig. 4, and by a jaw assembly 58 fixed in an adjustable manner on the rectilinear portion of the rod 55 by means of a support 59.

Le support 59 comporte une douille 60 traversée par la tige 55 et pourvu d'un dispositif d'immobilisation 61 à vis et bouton de manoeuvre et un manchon fileté 62 relié à la douille 60 par une portion intermédiaire 63. Une vis de serrage 64 pourvue à l'une de ses extrémités d'une poignée 65 et portant à son extrémité opposée une mâchoire 66 est engagée dans le manchon fileté 62.The support 59 comprises a socket 60 traversed by the rod 55 and provided with an immobilization device 61 with screw and operating button and a threaded sleeve 62 connected to the socket 60 by an intermediate portion 63. A tightening screw 64 provided at one of its ends of a handle 65 and carrying at its opposite end a jaw 66 is engaged in the threaded sleeve 62.

Par ailleurs, la presse-étau de la fig. 8 est semblable à la presse-étau de la fig. 4 et ne sera donc pas décrite davantage.Furthermore, the vise clamp of fig. 8 is similar to the vise clamp of FIG. 4 and will therefore not be described further.

La portion de rail de guidage représentée à la fig. 9 est une portion d'angle constituée de deux éléments modulaires rectilignes 67 réunis par un élément modulaire curviligne 68, ces éléments étant fixés sous le plateau 69 d'une table ou d'un établi, au moyen de vis 70.The portion of guide rail shown in fig. 9 is a corner portion made up of two rectilinear modular elements 67 joined by a curvilinear modular element 68, these elements being fixed under the plate 69 of a table or workbench, by means of screws 70.

On constate qu'un bâti tel que le bâti 20 pourvu d'une semelle 22 de forme circulaire, peut être déplacé librement le long du trajet défini par le rail constitué par l'assemblage des modules 67 et 68, à condition que la portion octogonale 51 de liaison entre la semelle 22 et les flasques 25 présente des dimensions légèrement inférieures à l'écartement entre les rebords rabattus de ces modules.It is noted that a frame such as the frame 20 provided with a sole 22 of circular shape, can be moved freely along the path defined by the rail formed by the assembly of the modules 67 and 68, provided that the octagonal portion 51 connecting between the sole 22 and the flanges 25 has dimensions slightly less than the spacing between the folded edges of these modules.
