Un ressort (6) entre les poignees (3) exerce une pression sur les machoires. Cette pression permet de maintenir entre les machoires divers elements. Des machoires amovibles de differentes dimensions ou formes ont la possibilite de venir se verrouiller sur les machoires de la pince, augmentant ainsi considerablement les possibilites d'utilisations de cette pince. Cette pince utilisee seule ou avec ses machoires amovibles a donc la possibilite de saisir-maintenir-inserer-ecarter etc... des elements tels que vis-ecrous-pointes-circlips-petites pieces servant pour mecanique, electricite, electronique, etc.Device allowing to constitute a manual clamp, this gives the possibility of grasping and holding between jaws, multiple elements: such as screw-nuts-points-small parts, etc. This clamp consists of two levers (1 and 2), engaging one inside the other and pivoting on an axis (4). A spring (6) between the handles (3) exerts pressure on the jaws. This pressure keeps various elements between the jaws. Removable jaws of different dimensions or shapes have the possibility of being locked on the jaws of the clamp, thus considerably increasing the possibilities of using this clamp. This clamp used alone or with its removable jaws therefore has the possibility of grasping-holding-inserting-spreading etc ... elements such as screw-nuts-points-circlips-small parts used for mechanics, electricity, electronics, etc.

Description

PINCE MANUELLE A MACHOIRES AMOVIBLES MANUAL PLIERS WITH REMOVABLE JAWS
La présente invention concerne l 'utilisation de différentes pièces et éléments, pour constituer une pince manuelle servant à de multiples usages.The present invention relates to the use of different parts and elements, to constitute a manual clamp used for multiple uses.
Tous les dispositifs manuels actuellement connus pour maintenir de petits éléments tels que : pointes, vis-écpous, rondelles etc, sont des pinces de toutes formes et de tous formats, souvent spécialement conçues pour certains travaux (notamment pour travailler dans des endroits peu accessibles) . Il était donc regrettable qu'il n'existe pas une pince pouvant s'adapter à faciliter l 'éxécution de multiples travaux. L'intérêt pratique suivant l 'invention est d'avoir avec une seule pince, la possibilité d' effectuer de multiples travaux, notamment minutieux et difficilement accessibles.All the manual devices currently known for holding small elements such as: points, screw-nuts, washers etc, are pliers of all shapes and all formats, often specially designed for certain jobs (especially for working in inaccessible places) . It was therefore regrettable that there was no clamp that could be adapted to facilitate the execution of multiple jobs. The practical advantage according to the invention is to have with a single pliers, the possibility of carrying out multiple works, in particular meticulous and difficult to access.
En effet, la conception de cet outil est telle, qu 'elle permet à la pince elle-même de saisir et maintenir de petits éléments, dans de très bonnes conditions et dans des endroits peu accessibles, mais ses possibilités d'utilisations sont considérablement augmentées par l 'adjonction (par un simple geste) sur les mâchoires de celle-ci, d'autres mâchoires, étudiées pour des travaux particulièrement difficiles. L 'invention réside dans les caractéristiques de combi¬naisons d' éléments et de dispositions de pièces qui sont décrites à titre d'exemples ci-aprés, en référence au dessins ci-annéxés. La figure 1 représente la pince en élévation, la figure 2 la mâchoire amovible en élévation, la figure 3 la pince en coupe suivant AB, la figure 4 la mâchoire amovible en coupe suivant CD.Indeed, the design of this tool is such that it allows the pliers themselves to grasp and hold small elements, in very good conditions and in places that are not easily accessible, but their possibilities of use are considerably increased. by adding (with a simple gesture) on the jaws thereof, other jaws, studied for particularly difficult work. The invention resides in the characteristics of combinations of elements and arrangements of parts which are described by way of examples below, with reference to the accompanying drawings. Figure 1 shows the clamp in elevation, Figure 2 the removable jaw in elevation, Figure 3 the clamp in section along AB, Figure 4 the removable jaw in section along CD.
Cette pince se compose de deux branches ou leviers 1 et 2. Chaque levier présente trois parties : à une extrémité des mâchoires effilées au centre la plaque de métal constituant l 'ensemble est découpée suivant un profil déterminé, et repliée en forme de U. L 'autre extrémité forme une partie de la poignée, cette partie est enrobée de matière plastique rigide, pour former la poignée complète (3) .This clamp consists of two branches or levers 1 and 2. Each lever has three parts: at one end of the jaws tapered in the center the metal plate constituting the assembly is cut according to a determined profile, and folded in the shape of U. L the other end forms a part of the handle, this part is coated with rigid plastic, to form the complete handle (3).
Dans la partie centrale du levier (1) , vient se loger la partie centrale du levier (2) . L'axe de pivot (4) traverse les deux leviers, l 'êcrou (5) est vissé sur la partie filetée de l 'axe (4) et maintien l 'ensemble, ainsi les deux leviers ont la possibilité de pivoter, dont les mâchoires de la pince de s 'écarter ou de se rapprocher.In the central part of the lever (1), is housed the central part of the lever (2). The pivot axis (4) crosses the two levers, the nut (5) is screwed onto the threaded part of the axis (4) and holds the assembly together, thus the two levers have the ability to rotate, including the jaws of the clamp to move apart or move closer.
Enroulé autour du pivot 4, nous avons un ressort 6 en spirale, dont les extrémités des branches font pression sur l 'intérieur des poignées 3. Cette pression permet de maintenir à l 'extrémité des mâchoires, dans les encoches (7) , des petits éléments tels, que pointes, écrous, vis, petites pièces etc. Ces éléments sont libères par pression des doigts de la main sur les deux poignées (3) . Pour permettre une fixation extrêmement rapide des mâchoires amoviblés (10) sur les mâchoires de la pince, celles-ci présentent les particularités ci-aprés : à la base des mâchoires de la pince est pratiqué un emboutissage en creux, donnant sur l 'autre face les bossages (8) . Dans le profil de la mâchoire, sur sa partie extérieure, est pratiqué un décrochement (9) formant butée. D 'autre part, les mâchoires amovibles (10) sont constituées, d'une bande de métal dont la découpe présente les pattes 11. 12. 13. Ces pattes sont repliées en forme de U de manière à former une glissière dont la largeur est sensiblement égale à l 'épaisseur des mâchoires de la pince. La découpe de la Mnde de métal présente à sa base une partie effilée, à son extrémité est pratiqué un emboutissage en creux (14) , de la même importance que celui exécuté sur les mâchoires de la pince.Wrapped around the pivot 4, we have a spiral spring 6, the ends of the branches of which press on the inside of the handles 3. This pressure makes it possible to maintain small jaws at the end of the jaws items such as spikes, nuts, screws, small parts, etc. These elements are released by pressing the fingers of the hand on the two handles (3). To allow extremely rapid fixing of the detachable jaws (10) on the jaws of the pliers, these have the following characteristics: at the base of the jaws of the pliers is a deep-drawing, giving on the other face the bosses (8). In the profile of the jaw, on its outer part, a recess (9) is formed forming a stop. On the other hand, the removable jaws (10) consist of a metal strip, the cutout of which presents the tabs 11. 12. 13. These tabs are folded in a U shape so as to form a slide whose width is substantially equal to the thickness of the clamp jaws. The cutting of the metal wave has at its base a tapered part, at its end there is a deep-drawing (14), of the same importance as that executed on the jaws of the pliers.
L'autre extrémité de la mâchoire amovible, peut présenter différentes formes, différentes longueurs, différentes encoches, être repliées suivant des angles différents, être magnétique etc.The other end of the removable jaw can have different shapes, different lengths, different notches, be folded at different angles, be magnetic etc.
Les mâchoires amovibles se fixent sur les mâchoires de la pince, en engageant les pattes 11-12-13 sur celles-ci et en les faisant glisser de la pointe vers la base, la patte (13) venant en butée sur le décrochement (9) . D 'autre part, étant donné que les mâchoires de la pince sont effilées, les mâchoires amovibles sont parfaitement maintenues, car elles viennent se bloquer par coincement vers la base de la mâchoire de la pince.The removable jaws are fixed on the jaws of the pliers, by engaging the tabs 11-12-13 on them and sliding them from the tip towards the base, the tab (13) coming into abutment on the recess (9 ). On the other hand, since the jaws of the pliers are tapered, the removable jaws are perfectly held, since they come to jam by jamming towards the base of the jaws of the pliers.
Le verrouillage de l 'ensemble est assuré par l 'engagement du bo/ssage (8) dans le creux (14) de la mâchoire amovible ; c 'est la flexibilité du métal de la partie, effilée qui assure ce verrouillage Les mâchoires amovibles sont séparées des mâchoires par le geste inverse de la fixation, c'est a aire en exerçant une traction sur les deux parties.The locking of the assembly is ensured by the engagement of the casing (8) in the hollow (14) of the removable jaw; it is the flexibility of the metal of the tapered part which ensures this locking. The removable jaws are separated from the jaws by the gesture reverse of the fixing, it is air by exerting a traction on the two parts.
L'objet de l 'invention de cette pince et de ses mâchoires amovibles conne la possibilité de saisir, maintenir, présenter, loger, incérer, écarter etc, des éléments tels que : vis-écrous-tiges-circlips-petites pièces servant pour réparations, fabrications, entretien d'appareillages et de matériels : mécaniques, électriques, téléphoniques, électroniques etc. Ces travaux peuvent être exécutés dans des endroits très difficilement, accessibles. The object of the invention of this clamp and its removable jaws includes the possibility of grasping, maintaining, presenting, accommodating, inserting, spreading, etc., elements such as: screw-nuts-rods-circlips-small parts used for repairs , manufacturing, maintenance of equipment and materials: mechanical, electrical, telephone, electronic, etc. These works can be carried out in very difficult, accessible places.
