Abstract

Polishing pad with rapid change of its abrasive parts and of specified flexibility. It consists of a parallelepipedal block 1 made of cellular rubber. Each of its two large faces is coated, removably by means of a fastening 6 with velvet and hooks, with an abrasive sheet 4 of chosen particle size.

Description

CALE DE PONCAGE MANUEL
La présente invention se rapporte à une cale manuelle destinée au ponçage.
MANUAL SANDING HOLDER
The present invention relates to a manual shim intended for sanding.

On connaît des dispositifs manuels de ponçage qui sont composés d'une cale parallélépipédique monobloc, en gomme agglomérée dans laquelle sont incorporés un grand nombre de grains abrasifs. Ces cales abrasives présentent quelques inconvénients. D'une part, la gomme s'use progressivement à l'usage de sorte que la forme de la cale varie et n'est alors souvent plus adaptée à certains travaux. D'autre part, ces cales sont prévues chacune pour une granulométrie définie, ce qui n'est pas toujours adapté au travail désiré. En outre, ces cales manquent parfois de souplesse, ce qui est préjudiciable à l'exécution de certains travaux. Manual sanding devices are known which are composed of a one-piece parallelepipedal block, of agglomerated rubber in which a large number of abrasive grains are incorporated. These abrasive wedges have some drawbacks. On the one hand, the eraser gradually wears out with use so that the shape of the shim varies and is therefore often no longer suitable for certain jobs. On the other hand, these shims are each provided for a defined particle size, which is not always suitable for the desired work. In addition, these wedges sometimes lack flexibility, which is detrimental to the execution of certain works.

L'invention vise à remédier à ces inconvénients. A cet effet, elle se rapporte à une cale manuelle de ponçage qui est constituée d'un bloc en matière semi-rigide de dureté choisie, par exemple en caoutchouc alvéolé, ce bloc comportant deux grandes faces planes et parallèles aptes chacune à assurer le ponçage au moyen d'une feuille abrasive, de mêmes dimensions, rapportée de manière amovible sur cette face au moyen d'un dispositif de fixation rapide à velours et crochets, tel que celui commercialisé sous la marque "VELCRO". Les granulométries de ces deux feuilles abrasives sont préférentiellement différentes. The invention aims to remedy these drawbacks. To this end, it relates to a manual sanding block which consists of a block of semi-rigid material of selected hardness, for example of cellular rubber, this block comprising two large flat and parallel faces each capable of ensuring sanding. by means of an abrasive sheet, of the same dimensions, removably attached to this face by means of a quick fastening device with velvet and hooks, such as that sold under the brand "VELCRO". The particle sizes of these two abrasive sheets are preferably different.

De toute façon, l'invention sera bien comprise, et ses avantages et autres caractéristiques ressortiront, au cours de la description suivante d'un exemple non limitatif de réalisation de cette cale de ponçage, en référence au dessin schématique annexé dans lequel
Figure 1 est une vue en perspective de la cale, avec un coin de feuille abrasive relevé pour faire voir son dispositif de fixation rapide à velours et crochets
Figure 2 est une vue en coupe selon II-II de figure I, avec là aussi un morceau de feuille abrasive relevé.
In any case, the invention will be well understood, and its advantages and other characteristics will emerge during the following description of a nonlimiting example of embodiment of this sanding block, with reference to the appended schematic drawing in which
Figure 1 is a perspective view of the wedge, with a corner of the abrasive sheet raised to show its quick fastening device with velvet and hooks
Figure 2 is a sectional view along II-II of Figure I, again with a piece of raised abrasive sheet.

La cale de ponçage représentée aux figures 1 et 2 se compose d'un bloc 1 en caoutchouc alvéolé de dureté choisie et de forme parallélépipédique. Ce bloc 1 est recouvert, sur chacune de ses deux grandes faces 2 et 3, d'une feuille abrasive amovible, respectivement 4 et 5, la feuille 4 étant par exemple une feuille abrasive à gros grains, tandis que la feuille 5 est une feuille abrasive à grains fins. The sanding block shown in Figures 1 and 2 consists of a block 1 of cellular rubber of selected hardness and parallelepiped shape. This block 1 is covered, on each of its two large faces 2 and 3, with a removable abrasive sheet, respectively 4 and 5, the sheet 4 being for example a coarse abrasive sheet, while the sheet 5 is a sheet fine grain abrasive.

Chaque feuille abrasive, 4 ou 5, est fixée sur la face correspon dante, 2 ou 3, à l'aide d'un dispositif de fixation rapide 6 à velours et crochets, tel que par exemple celui commercialisé sous la marque "VELCRO". Dans l'exemple considéré, la partie "velours" 7 de la fixation, telle que la fixation 6, est collée sur la grande face respective 2 du bloc 1, tandis que la partie complémentaire, ou "crochets" 8 de cette fixation est collée au verso de la feuille abrasive, telle que la feuille 4. Bien entendu, la disposition inverse pour les parties complémentaires 7,8 peut aussi être adoptée. Each abrasive sheet, 4 or 5, is fixed to the corresponding face, 2 or 3, using a quick fastening device 6 with velvet and hooks, such as for example that sold under the brand "VELCRO". In the example considered, the "velvet" part 7 of the binding, such as the binding 6, is glued to the respective large face 2 of the block 1, while the complementary part, or "hooks" 8 of this binding is glued on the back of the abrasive sheet, such as sheet 4. Of course, the reverse arrangement for the complementary parts 7,8 can also be adopted.

Selon la matière choisie pour le bloc 1, on obtient des cales de différentes duretés. Les feuilles abrasives 4 et 5 sont aisément amovibles, de sorte que le remplacement des feuilles usagées est quasi instantané. Une même cale permet d'effectuer, sans changement de feuilles abrasives, un ponçage à gros grains (feuille 4) suivi d'un ponçage à grains fins (feuille 5). Il est aussi possible d'exécuter, avec la même cale, une série de ponçages successifs à grains différents, par exemple de plus en plus fins : il suffit pour celà de remplacer une feuille abrasive par une autre également pourvue d'une partie 8 (velours ou crochet) complémentaire de la partie 7 (crochet ou velours) qui revêt la face 2 correspondante du bloc semi-rigide 1. Depending on the material chosen for block 1, shims of different hardness are obtained. The abrasive sheets 4 and 5 are easily removable, so that the replacement of the used sheets is almost instantaneous. The same shim makes it possible, without changing the abrasive sheets, to coarse sanding (sheet 4) followed by fine sanding (sheet 5). It is also possible to carry out, with the same shim, a series of successive sandings with different grains, for example increasingly fine: it suffices for this to replace one abrasive sheet with another also provided with a part 8 ( velvet or hook) complementary to part 7 (hook or velvet) which covers the corresponding face 2 of the semi-rigid block 1.

L'invention n'est bien entendu pas limitée à l'exemple de réalisation qui vient d'être décrit, mais elle en embrasse bien au contraire toutes les variantes de réalisation. Par exemple, la cale, tout en étant pourvue de deux grandes faces parallèles, peut ne pas être parallélépipédique, mais avoir une forme plus esthétique et/ou mieux adaptée à une préhension manuelle confortable.  The invention is of course not limited to the embodiment which has just been described, but on the contrary it embraces all the variant embodiments thereof. For example, the wedge, while being provided with two large parallel faces, may not be parallelepipedic, but have a more aesthetic shape and / or better suited to comfortable manual gripping.
