Description

La présente invention concerne un dispositif de finition de surface et plus particulièrement un élément éventuellement pourvu d'un accessoire pour poncer, décaper, polir ou effectuer un traitement analogue à une surface plane ou incurvée, en bois, métal, plastique, etc.. dans l'industrie de l'automobile, du bois, du bâtiment, etc..The present invention relates to a surface finishing device and more particularly to an element possibly provided with an accessory for sanding, pickling, polishing or performing a treatment analogous to a flat or curved surface, of wood, metal, plastic, etc. in automotive, wood, construction, etc.

Cette invention trouve une utilisation intéressante dans le domaine du "bricolage".This invention finds an interesting use in the field of "DIY".

Généralement, les accessoires de finition de surface sont fixés sur un support semi-rigide lui-même accouplé fixement à un moteur. De tels appareils, notamment lors de l'utilisation en ponçage, présentent l'inconvénient de sauter même sur une surface lisse et surtout de strier la surface, sous forme de traces en arc de cercle.Generally, the surface finishing accessories are fixed on a semi-rigid support which is itself fixedly coupled to a motor. Such devices, especially when used for sanding, have the disadvantage of jumping even on a smooth surface and especially of streaking the surface, in the form of traces in an arc.

Ces inconvénients résultent de la rigidité du support qui ne permet ni un amortissement lors du contact ni une adaptation de l'outil pour ajuster l'accessoire en parallélisme avec la surface travaillée.These drawbacks result from the rigidity of the support which allows neither damping during contact nor an adaptation of the tool to adjust the accessory in parallel with the worked surface.

Une première approche a été d'insérer entre l'accessoire et son support, un tampon élastique en matériau alvéolaire (voir par exemple le brevet U.S. 2 950 584 délivré le 30 août 1960) ou une enceinte déformable remplie d'air (brevet U.S. 2 644 280 délivré le 7 Juillet 1953).A first approach was to insert between the accessory and its support, an elastic plug of cellular material (see for example US Pat. 2,950,584 issued on August 30, 1960) or a deformable enclosure filled with air (US Patent 2 644,280 issued July 7, 1953).

Si cette technique permet de résoudre en partie les problèmes de l'amortissement, il en est autrement de l'inclinaison qui est insuffisante pour s'adapter au plan de la surface travaillée.If this technique partially solves the problems of damping, it is different from the inclination which is insufficient to adapt to the plane of the surface worked.

Une seconde approche consiste à monter un joint de cardan de manière à modifier l'inclinaison de l'accessoire par rapport à la surface (voir le brevet F 2 193 342 déposé le 17 Février 1972).A second approach consists in mounting a universal joint so as to modify the inclination of the accessory relative to the surface (see patent F 2 193 342 filed on February 17, 1972).

Cette technique en plus de son coût prohibitif ne résout que l'inclinaison, sans être homocinétique.This technique in addition to its prohibitive cost only solves the inclination, without being homokinetic.

Ces solutions n'ont donc pas donné jusqu'à présent satisfaction et l'on ne trouve pas actuellement sur le marché un outil rotatif adaptable sur un moteur remplissant correctement la fonction notamment de ponçage et ce pour un prix abordable pour une utilisation épisodique et même professionnelle.These solutions have therefore not been satisfactory so far and there is currently no rotary tool adaptable on a motor correctly fulfilling the function in particular of sanding and this for an affordable price for episodic use and even professional.

L'invention a trait à l'obtention d'un dispositif de finition de surface répondant à ces besoins.The invention relates to obtaining a surface finishing device meeting these needs.

Ce dispositif comprend un organe dont une extrémité peut être accouplée à un dispositif de mise en rotation, moteur électrique portatif par exemple, et dont l'autre extrémité terminale peut être pourvue d'un accessoire de finition de surface, l'organe étant élastique pour permettre un débattement suivant son axe longitudinal et présente au moins un étranglement annulaire aménagé à partir de la surface latérale de l'organe. Cet organe peut être évidé et réalisé en caoutchouc naturel ou synthétique moulé, ou en toile moulée enrobée de caoutchouc ou matière élastique.This device comprises a member, one end of which can be coupled to a rotation device, portable electric motor for example, and the other terminal end of which can be provided with a surface finishing accessory, the member being elastic for allow a travel along its longitudinal axis and has at least one annular constriction arranged from the lateral surface of the organ. This member can be hollowed out and made of molded natural or synthetic rubber, or of molded canvas coated with rubber or elastic material.

Avantageusement, l'organe a la forme d'un soufflet constitué d'au moins deux parois sensiblement tronconiques opposées par leurs grandes bases et se raccordant, par un étranglement, à l'extrémité terminale.Advantageously, the member has the form of a bellows consisting of at least two substantially frustoconical walls opposite by their large bases and connecting, by a constriction, to the terminal end.

L'extrémité terminale peut être munie d'une platine sensiblement circulaire, éventuellement rigide, qui peut dans ce cas comporter des stries ou être constituée d'une résille de fils abrasifs.The terminal end may be provided with a substantially circular plate, possibly rigid, which in this case may have ridges or be made up of a mesh of abrasive wires.

Suivant une forme préférée de l'invention, la platine comporte à sa périphérie un bord tombé qui coopère avec une protubérance annulaire ou jonc périphérique aménagé à l'extrémité terminale de l'organe.According to a preferred form of the invention, the plate comprises at its periphery a fallen edge which cooperates with an annular protuberance or peripheral rod arranged at the terminal end of the member.

En variante, la platine comporte, à la place d'un bord tombé périphérique, une nervure, recourbée, annulaire située sur la platine et qui coopère avec la protubérance annulaire ou jonc périphérique aménagé à l'extrémité terminale de l'organe.As a variant, the plate comprises, in place of a peripheral fallen edge, a curved, annular rib situated on the plate and which cooperates with the annular protuberance or peripheral rod arranged at the terminal end of the member.

Suivant une autre forme de réalisation, l'extrémité terminale est constituée d'une paroi tronconique évasée vers l'extérieur et sur laquelle est fixé ou collé ou disque déformable.According to another embodiment, the terminal end consists of a frustoconical wall flared towards the outside and on which is fixed or glued or deformable disc.

L'organe comporte également un insert pour coopérer avec un moyen d'accouplement.The member also includes an insert for cooperating with a coupling means.

La description qui va suivre, en regard des dessins annexés, donnée à titre d'exemple non limitatif, fera bien comprendre comment l'invention peut être réalisée

  • La figure 1 est une vue en coupe d'un premier mode de réalisation d'un organe suivant l'invention.
  • La figure 2 est une vue à plus grande échelle d'un détail A de l'extrémité terminale. La figure 3 est une vue en coupe d'un exemple de réalisation de platine. La figure 4 est une vue à plus grande échelle d'un détail B de la platine. La figure 5 est une vue analogue à la figure 3 montrant une variante de réalisation de platine. La figure 6 est une vue analogue à la figure 1 montrant un deuxième mode de réalisation de l'organe.
The description which follows, with reference to the appended drawings, given by way of nonlimiting example, will make it clear how the invention can be implemented.
  • Figure 1 is a sectional view of a first embodiment of a member according to the invention.
  • Figure 2 is an enlarged view of a detail A of the terminal end. Figure 3 is a sectional view of an exemplary embodiment of the plate. Figure 4 is an enlarged view of a detail B of the plate. Figure 5 is a view similar to Figure 3 showing an alternative embodiment of the plate. Figure 6 is a view similar to Figure 1 showing a second embodiment of the member.

En se reportant à la figure 1, on peut voir un dispositif de finition de surface comprenant un organe 1 dont l'extrémité 2 peut être accouplée à un dispositif de mise en rotation, moteur électrique portatif par exemple et dont l'autre extrémité terminale 3 peut être pourvue d'un accessoire de finition de surface. Cet organe est avantageusement évidé et réalisé en matière élastique telle qu'en caoutchouc naturel ou synthétique moulé, ou en toile moulée enrobée de caoutchouc.Referring to Figure 1, we can see a surface finishing device comprising a member 1 whose end 2 can be coupled to a rotation device, portable electric motor for example and whose other terminal end 3 may be provided with a surface finishing accessory. This member is advantageously hollowed out and made of elastic material such as molded natural or synthetic rubber, or of molded canvas coated with rubber.

Vu en coupe suivant un plan longitudinal, l'organe présente une configuration en forme de soufflet constitué de deux parois sensiblement tronconiques 4 et 5 opposées par leur grande base et se raccordant d'une part à l'extrémité 2 et d'autre part par un étranglement annulaire 6 à l'extrémité terminale 3.Seen in section along a longitudinal plane, the member has a bellows-shaped configuration consisting of two substantially frustoconical walls 4 and 5 opposite by their large base and connecting on the one hand to the end 2 and on the other hand by an annular constriction 6 at the terminal end 3.

Suivant une variante non représentée, les deux parois peuvent s'évaser vers l'extrémité terminale, la grande base de l'une se raccordant à la petite base de l'autre.According to a variant not shown, the two walls can flare towards the terminal end, the large base of one connecting to the small base of the other.

L'extrémité terminale 3 se présente sous la forme d'un disque plan évidé en son centre dont l'épaisseur décroît de l'intérieur vers l'extérieur (détail figure 2) pour, à sa périphérie, comporter une protubérance annulaire 7 ou jonc périphérique.The terminal end 3 is in the form of a flat disc hollowed out at its center, the thickness of which decreases from the inside towards the outside (detail in figure 2) so as to have, at its periphery, an annular protuberance 7 or rod peripheral.

Cette protubérance peut coopérer avec un bord tombé 8 (figures3 et 4) ou une nervure 9 (figure 5) d'une platine 10 rigide qui est amovible. Cette platine peut être elle-même abrasive par incorporation de stries ou être constituée d'une résille de fils abrasifs. La platine 10 peut être également, d'une manière connue en soi, le support d'un accessoire de finition de surface pour polir, lustrer ou abraser.This protuberance can cooperate with a fallen edge 8 (Figures 3 and 4) or a rib 9 (Figure 5) of a rigid plate 10 which is removable. This plate can itself be abrasive by incorporating streaks or be made up of a mesh of abrasive wires. The plate 10 can also be, in a manner known per se, the support of a surface finishing accessory for polishing, buffing or abrading.

Cet accessoire peut être fixé au centre de la platine grâce à une vis ou bouchon dont la tête s'efface dans un logement II par exemple embouti.This accessory can be fixed to the center of the plate by means of a screw or plug whose head disappears in a housing II, for example stamped.

La platine 10 peut être en métal, acier par exemple protégé, embouti ou découpé à partir d'une plaque. Elle peut être également en plastique moulé notamment dans le cas de la variante représentée figure 5. Cette variante présente l'avantage de disposer d'un jeu de platines de différents diamètres qui peuvent s'adapter sur un même organe. Elle convient particulièrement bien à une utilisation pour dresser une surface sans ressaut.The plate 10 can be made of metal, for example protected steel, stamped or cut from a plate. It can also be made of molded plastic, in particular in the case of the variant shown in FIG. 5. This variant has the advantage of having a set of plates of different diameters which can be adapted on the same member. It is particularly well suited for use for erecting a surface without projections.

Le mode de réalisation de l'organe illustré figure 6 diffère essentiellement de celui précédemment décrit par son extrémité terminale 12 légèrement tronconique et d'épaisseur décroissante jusqu'à son extrémité. Ce mode de réalisation convient particulièrement bien pour un élément de finition souple déformable, qui peut être fixé, par collage par exemple, et utilisé pour poncer, lustrer ou polir notamment des reliefs.The embodiment of the member illustrated in FIG. 6 essentially differs from that previously described by its terminal end 12 slightly frustoconical and of thickness decreasing to its end. This embodiment is particularly suitable for a flexible deformable finishing element, which can be fixed, by gluing for example, and used to sand, polish or polish in particular reliefs.

L'extrémité accouplable de l'organe est muni d'un insert 13, moulé avec l'organe. Cet insert lui est solidaire par des redents 14, figure 1 ou des pans coupés 15 (figure 6).The couplable end of the member is provided with an insert 13, molded with the member. This insert is secured to it by redents 14, FIG. 1 or cut sides 15 (FIG. 6).

Un axe 16 intégré (figure 6) ou amovible (non représenté figure 1) permet d'accoupler l'organe au mandrin d'un moteur.An integrated axis 16 (FIG. 6) or removable (not shown in FIG. 1) makes it possible to couple the member to the mandrel of an engine.

On remarquera que la paroi tronconique 4 peut présenter une épaisseur croissante pour améliorer la tenue mécanique et la continuité avec l'extrémité 2.It will be noted that the frustoconical wall 4 may have an increasing thickness in order to improve the mechanical strength and the continuity with the end 2.

Le fonctionnement de l'invention découle de la description qui vient d'en être donnée. On notera que pour un coût modique on réalise un organe intermédiaire entre un moteur et un accessoire de finition qui assure à la fois l'amortissement et l'adaptation de l'inclinaison de son extrémité terminale et de la surface à travailler.The operation of the invention follows from the description which has just been given. It will be noted that, for a low cost, an intermediate member is produced between a motor and a finishing accessory which ensures both the damping and the adaptation of the inclination of its terminal end and of the surface to be worked.

L'amortissement est donné d'une part par le matériau élastique utilisé et d'autre part, par la forme en soufflet de l'organe qui permet une rétraction longitudinale.The damping is given on the one hand by the elastic material used and on the other hand, by the bellows shape of the member which allows a longitudinal retraction.

L'adaptation à l'inclinaison est réalisée par l'étranglement annulaire qui joue le rôle d'une rotule, en compensant l'obliquité entre le plan de l'accessoire de finition et la surface par une rotation autour de cet étranglement.Adaptation to the inclination is achieved by the annular constriction which acts as a ball joint, by compensating for the obliquity between the plane of the finishing accessory and the surface by a rotation around this constriction.

La forme donnée au soufflet permet un rappel en position non-travaillante et une stabilisation par effet gyroscopique.The shape given to the bellows allows a return to the non-working position and stabilization by gyroscopic effect.

A titre d'exemple non limitatif, l'extrémité terminale du mode de réalisation exposé figure 1 a un diamètre de 122 mm pour une hauteur de 60 mm. Sur cette extrémité, on peut adapter une platine de diamètre 122 mm ou plus, 160 mm par exemple. L'extrémité terminale du mode de réalisation exposé figure 6 a un diamètre de 20 mm.By way of nonlimiting example, the terminal end of the embodiment shown in FIG. 1 has a diameter of 122 mm for a height of 60 mm. On this end, a plate with a diameter of 122 mm or more, 160 mm for example, can be adapted. The terminal end of the embodiment shown in Figure 6 has a diameter of 20 mm.

Le dispositif suivant l'invention s'applique particulièrement bien au dressage et à la finition de surface telle que ponçage, lustrage, polissage par adaptation d'un accessoire de finition correspondant, ainsi qu'au ponçage de relief.The device according to the invention applies particularly well to dressing and surface finishing such as sanding, buffing, polishing by adaptation of a corresponding finishing accessory, as well as to sanding in relief.
