Description

L'invention concerne une pince de manipulation de disques et d'autres objets plats et minces, susceptibles aux rayures, à la pollution, à la contamination, ou dont la manipulation répétée présente certains risques pour les doigts.The invention relates to forceps for handling discs and other flat and thin objects, susceptible to scratches, pollution, contamination, or the repeated handling of which presents certain risks for the fingers.

La manipulation des disques phonographiques ou vidéo, des plaques photographiques, des circuit imprimés, des plaques de silicium utilisées pour la fabrication de cellules photovoltaîques, des microfiches, des objets stériles ou, au contraire contaminés, exige de grandes précautions visant à réduire, selon le cas, les risques de détérioration par rayures ou par souillure, de pollution ou de contamination.The handling of phonographic or video discs, photographic plates, printed circuits, silicon plates used for the manufacture of photovoltaic cells, microfiche, sterile objects or, on the contrary contaminated, requires great precautions aiming at reducing, according to the In this case, the risks of damage by scratches or by soiling, pollution or contamination.

Les disques microsillon ou vidéo, proposés actuellement sur le marché, sont devenus des produits de haute précision capables de restituer des sons ou des images avec une grande fidélité et un minimum d'altération. La qualité de cette restitution dépend, bien sûr, de l'intégrité et de la propreté des disques: ce qui oblige les utilisateurs à prendre de grandes précautions lors de la préhension et de la manipulation, afin d'éviter les rayures par les ongles, les bagues ou les bracelets et toute souillure par les doigts, car les rayures et les salissures se traduisent respectivement par des "tocs" et des "grésillements" qui perturbent l'audition.Microgroove or video discs, currently offered on the market, have become high-precision products capable of reproducing sounds or images with great fidelity and a minimum of alteration. The quality of this restitution depends, of course, on the integrity and cleanliness of the discs: which obliges users to take great precautions during gripping and handling, in order to avoid scratching by the nails, rings or bracelets and any stain by the fingers, because the scratches and the stains result respectively in "knocks" and "crackles" which disturb the hearing.

Dans les domaines de l'électronique, de la photographie et de l'imprimerie, c'est principalement la pollution par la substance acide secrétée par les diogts, que l'on cherche à éviter pour des raisons de corrosion ou de perturbation des traitements ultérieurs.In the fields of electronics, photography and printing, it is mainly pollution by the acid substance secreted by the diogts, which we seek to avoid for reasons of corrosion or disruption of subsequent treatments .

Dans les domaines biologique et médical, ce sont les risques de contamination bactériologique et microbienne, lors des manipulations ou des analyses, qui doivent être éliminés. Or, les doigts, en particulier au nievau des ongles, sont susceptibles de transmettre cette contamination.In the biological and medical fields, it is the risks of bacteriological and microbial contamination, during handling or analyzes, which must be eliminated. However, the fingers, in particular at the level of the nails, are capable of transmitting this contamination.

Dans le domaine nucléaire, c'est la manipulation d'objets contaminée par des particules radioactives, lors des operations de décontamination, qui expose les exécutants à des risques certains.In the nuclear field, it is the manipulation of objects contaminated by radioactive particles, during decontamination operations, which exposes the performers to certain risks.

Dans d'autres domaines, c'est la manipulation répétée d'objets très rugeux tels que des disques de meules, par exemple, ou des feuilles d'abrasifs, quie entraîne une usure et une irritation de l'épiderme à l'extrémité des doigts.In other fields, it is the repeated handling of very rougher objects such as grinding wheel discs, for example, or abrasive sheets, which causes wear and irritation of the epidermis at the ends of the fingers.

Pour ces manipulations, des gants ou des pinces, conçus spécialement pour ces différents usages, sont déjà utilisés.For these manipulations, gloves or tongs, specially designed for these different uses, are already used.

On cannaît notamment des pinces de manipulation de disques correspondant au préambule de la revendication 1 (Brevets: français A.2.040.678 et A.2.393.653; U.S.A. A.1.365.227; belge A.555.159). Il s'agit respectivement de pinces: à becs courbes, qui permet de saisir le disque par sa bordure en dehors de la surface gravée; à becs plats recouverts de matière plastique, qui permet de saisir le disque dans la zône gravée; à longs becs plats, dont l'extrêmité est munie de tampons permettant la saisie du disque par sa partie centrale non gravée; à becs flexibles, du type pincette, permettant la saisie du disque dans la zône gravée.In particular, disc handling tongs corresponding to the preamble of claim 1 are released (Patents: French A.2.040.678 and A.2.393.653; U.S.A. A.1.365.227; Belgian A.555.159). They are respectively pliers: with curved beaks, which allows the disc to be grasped by its border outside the engraved surface; with flat beaks covered with plastic, which allows the disc to be grasped in the engraved area; with long flat beaks, the end of which is provided with buffers allowing the disc to be grasped by its unetched central part; with flexible beaks, of the tweezer type, allowing the gripping of the disc in the engraved zone.

La pince à becs courbes, qui permet de saisir le disque par sa bordure en dehors de la surface gravée, exige d'être utilisée avec précautions, car une manipulation un peu brusque pourrait provoquer une déformation, voire un rupture, de la bordure. Celle à becs plats recouverts de maitiére plastique est équipée de bras du type ciseaux, ce qui oblige à entretenir une pression avec deux doigts pendant toute la durée de la manipulation. Toutes ces pinces, à l'exception de celle du type pincette, obligent à entretenir une pression constante de la main pendant toute la durée de la manipulation, y compris lors des changements de face, ce qui impose de relayer cette pression à l'aide de l'autre main, pour éviter une rotation pénible du poignet, lors du retournement.The curved-nose pliers, which allow the disc to be grasped by its edge outside the engraved surface, require to be used with care, as a little rough handling could cause deformation, or even rupture, of the edge. The one with flat beaks covered with plastic material is fitted with scissor-type arms, which means that pressure has to be maintained with two fingers during the entire manipulation. All of these pliers, with the exception of that of the tweezer type, make it necessary to maintain constant pressure of the hand throughout the duration of the manipulation, including during changes of face, which means that this pressure must be relayed using with the other hand, to avoid a painful rotation of the wrist, when turning.

Aucune de ces pinces n'est équipée d'un réglage précis et permanent de la pression exercée par les mâchoires, en fonction de l'épaisseur, de la masse et des dimensions du disque, et n'a été conçue pour faciliter l'insertion des becs dans la pochette, ni pour éviter la rayure des disques voisins avec le dos des becs. Les mâchoires ne sont pas appliquées l'une contre l'autre au repos; ce qui favorise le dépôt de poussières abrasives sur leur surface travaillante.None of these clamps is equipped with a precise and permanent adjustment of the pressure exerted by the jaws, as a function of the thickness, mass and dimensions of the disc, and has not been designed to facilitate insertion. spouts in the pocket, or to avoid scratching neighboring discs with the back of the spouts. The jaws are not pressed against each other at rest; which promotes the deposition of abrasive dust on their working surface.

La présente invention a pour but de remédier à ces inconvénients. La pince objet de l'invention, telle qu'elle est caractérisée dans les revendications, se distingue principalement en ce que les mâchoires sont rappelées l'une contre l'autre, par un ressort à tension réglable; les mordaches sont reliées entre elles par une articulation distincte de celle des bras de manoeuvre des mâchoires et servant à limiter la pénétration entre les mâchoires, de l'objet à manipuler; en ce qu'elle est munie de dispositifs facilitant l'insertion des mâchoires entre les objets et protégeant les objets voisins superposés ou juxtaposés.The present invention aims to remedy these drawbacks. The clamp object of the invention, as characterized in the claims, is mainly distinguished in that the jaws are biased against each other, by an adjustable tension spring; the jaws are interconnected by an articulation distinct from that of the jaw operating arms and serving to limit the penetration between the jaws of the object to be handled; in that it is provided with devices facilitating the insertion of the jaws between the objects and protecting the neighboring objects superimposed or juxtaposed.

Les avantages obtenus grâce à cette invention, consistent essentiellement en ce que la force de serrage des mâchoires de la pince est réglable en fonction de la nature, de l'épaisseur et de la masse de l'objet à manipuler; le retournement de l'objet peut être obtenu par simple rotation des bras de la pince dans la paume de la main; le pénétration de l'objet entre les mâchoires est limitée de façon à éliminer tout risque de pincement de celui-ci au niveau de l'articulation; la pénétration des mâchoires entre des objets juxtaposés est facilitée; tout risque de rayures des objets voisins est éliminé; la poussière ne peut pas se déposer sur la face interne des mordaches, pendant lés périodes d'inutilisation, puisque celles-ci sont alors appliquées l'une contre l'autre.The advantages obtained thanks to this invention consist essentially in that the clamping force of the jaws of the clamp is adjustable depending on the nature, thickness and mass of the object to be handled; the turning of the object can be obtained by simple rotation of the arms of the forceps in the palm of the hand; the penetration of the object between the jaws is limited so as to eliminate any risk of pinching it at the joint; the penetration of jaws between juxtaposed objects is facilitated; any risk of scratches on neighboring objects is eliminated; dust cannot be deposited on the internal face of the jaws, during the periods of inactivity, since these are then applied one against the other.

D'autres caractéristiques et avantages de l'invention, apparaîtront dans la description qui va suivre, d'un mode de réalisation particulier, donné à titre d'exemple, illustré par des dessins sur lesquels:

  • La figure 1 représente une vue de côté de la pince, réalisée conformément à la présente invention.
  • La figure 2 représente une vue de face de la pince équipée de ses mordaches.
Other characteristics and advantages of the invention will appear in the description which follows, of a particular embodiment, given by way of example, illustrated by drawings in which:
  • Figure 1 shows a side view of the clamp, produced in accordance with the present invention.
  • FIG. 2 represents a front view of the pliers equipped with its jaws.

Les figures représentant une pince de manipulation de disques phonographiques et d'autres objets plats et minces, comprenant essentiellement deux bras 1 articulés autour de l'axe 2, soumis à une force d'écartement produite par un ressort 3 à tension réglable par un écrou moleté 8, monté sur un axe fileté 9 solidaire de l'un des bras, prolongés par les mâchoires 4 sur lesquelles se montent les mordaches 5, reliées et articulées entre elles par le pli 6 formant limiteur de pénétration; les mordaches 5 sont retenues contre la face interne des mâchoires 4 par un bord rabattu 10, soudé sur toute sa largeur, au niveau du pli d'articulation 6 par les cordons de soudure 11; les mordaches possèdent chacune une partie effilée 7, à leur extrémité: les bras 1 sont reliés aux mâchoires 4 par un épanoui 12 dépourvu d'arête vive, dont l'épaisseur est inférieure à celle du bord rabattu 10.The figures representing a gripper for handling phonographic discs and other flat and thin objects, essentially comprising two arms 1 articulated around the axis 2, subjected to a spacing force produced by a spring 3 with adjustable tension by a nut knurled 8, mounted on a threaded pin 9 secured to one of the arms, extended by the jaws 4 on which the jaws 5 are mounted, connected and articulated together by the fold 6 forming a penetration limiter; the jaws 5 are retained against the internal face of the jaws 4 by a folded edge 10, welded over its entire width, at the level of the articulation fold 6 by the weld beads 11; the jaws each have a tapered part 7, at their end: the arms 1 are connected to the jaws 4 by an openwork 12 devoid of sharp edges, the thickness of which is less than that of the folded edge 10.

Conformément à la présente invention, le mâchoires 4a et 4b, munies de leurs mordaches 5a et 5b, sont rappelées en permanence l'une contre l'autre, par les ressort 3, monté entre les bras 1 a et 1 b, de façon à exercer une force suffisante au serrage de l'objet et à l'immobilisation de celui-ci par rapport à la pince; lorsque l'objet est ainsi maintenu, il peut être aisément manipulé ou retourné par simple déplacement de la pince ou rotation de celle-ci dans la main. La force de serrage des mâchoires 4 peut être réglée de façon précise, en fonction de l'épaisseur, de la masse et des dimensions de l'objet, an agissant sur l'écrou moleté 8. Lors de la mise en place de la pince sur l'objet, les extrêmités effilées 7a et 7b facilitent l'insertion des mâchoires dans les pochettes de conditionnement, entre des objets juxtaposés ou entre un objet et son support.In accordance with the present invention, the jaws 4a and 4b, provided with their jaws 5a and 5b, are permanently urged against each other, by the springs 3, mounted between the arms 1a and 1b, so as to exert sufficient force to tighten the object and immobilize it relative to the clamp; when the object is thus held, it can be easily manipulated or turned over by simply moving the clamp or rotating it in the hand. The clamping force of the jaws 4 can be adjusted precisely, as a function of the thickness, the mass and the dimensions of the object, by acting on the knurled nut 8. During the positioning of the clamp on the object, the tapered ends 7a and 7b facilitate the insertion of the jaws into the packaging pouches, between juxtaposed objects or between an object and its support.

Selon un mode de réalisation préféré de l'invention, l'une des extrêmités effilée 7b est légèrement en retrait, par rapport à l'extrémité 7a de l'autre mordache, de façon à faciliter la présentation de la pince sur le bord de l'objet à manipuler, puis l'insertion de celui-ci entre les mâchoires. La présence d'un limiteur de pénétration 6 distinct de l'axe d'articulation 2, permet une mise en place rapide sur l'objet, sans précaution particulière, puisque la bordure de l'objet ne risque aucune détérioration et que les objets voisins sont protégés de toute rayure par le bord rabattu 10, dont l'épaisseur est déterminée de façon à éliminer tout risque de contact avec l'épanoui 12 assurant la liaison entre les bras et les mâchoires. Les mordaches 5 étant réalisées en une seule partie, dans une matière souple, puis ramenées l'une contre l'autre, pour former un pli d'articulation 6, ce pli, . bien que situé très en avant de l'axe d'articulation 2, est assez élastique pour permettre une ouverture suffisante de la pince lorsqu'un effort de rapprochement est exercé sur le bras 1. Cette conception offre, en outre, l'avantage de permettre un contact parfait des mordaches l'une contre l'autre, sous l'action du ressort 3: ce qui élimine tout risque de dépôt de poussière ou d'autres pollutions pendant les périodes d'inutilisation. Les mordaches 5 peuvent être facilement mises en place sur les mâchoires 4, du fait de l'elasticité des bords rabattus 10, malgré la présence des cordons de soudure 11, qui s'opposent ensuite à tout glissement des mordaches 5 par rapport aux mâchoires 4.According to a preferred embodiment of the invention, one of the tapered ends 7b is slightly set back, relative to the end 7a of the other jaw, so as to facilitate the presentation of the pliers on the edge of the object to be handled, then inserting it between the jaws. The presence of a penetration limiter 6 separate from the articulation axis 2, allows rapid installation on the object, without any special precautions, since the edge of the object does not risk any deterioration and that neighboring objects are protected from any scratch by the folded edge 10, the thickness of which is determined so as to eliminate any risk of contact with the breakout 12 ensuring the connection between the arms and the jaws. The jaws 5 being produced in a single part, in a flexible material, then brought back one against the other, to form an articulation fold 6, this fold,. although located very in front of the hinge axis 2, is elastic enough to allow sufficient opening of the clamp when a force of approximation is exerted on the arm 1. This design also offers the advantage of allow perfect contact of the jaws against each other, under the action of spring 3: which eliminates any risk of depositing dust or other pollution during periods of non-use. The jaws 5 can be easily placed on the jaws 4, due to the elasticity of the folded edges 10, despite the presence of the weld beads 11, which then oppose any sliding of the jaws 5 relative to the jaws 4 .

La pince objet de l'invention, peut être utilisée dans tous les cas où la manipulation d'objets plats et minces exige de grandes précautions et tout particulièrement, lorsque ces objets sont très sensibles aux rayures, à la pollution ou à la contamination, ou lorsque leur manipulation répétée présente certains risques pour les doigts. Elle peut être utilisée dans les domaines de l'audio-visuel, de l'électronique, de la photographie, de la biologie et du nucléaire.The forceps object of the invention can be used in all cases where handling flat and thin objects requires great precautions and especially, when these objects are very sensitive to scratches, pollution or contamination, or when their repeated handling presents certain risks for the fingers. It can be used in the audio-visual, electronics, photography, biology and nuclear fields.
