Description

La présente invention concerne le domaine des dispositifs pour imprégner de peinture un outil d'application.The present invention relates to the field of devices for impregnating an application tool with paint.

Il est connu, pour imprégner un outil d'application tel qu'une brosse ou un rouleau de disposer la peinture dans un récipient et de munir celui-ci d'une grille, accrochée sur un rebord dudit récipient, pour essorer l'outil d'application après l'avoir immergé dans la peinture. Un tel dispositif selon l'art antérieur est représenté à titre d'illustration sur la figure 1, où l'on aperçoit le récipient 10 contenant la peinture P et la grille 20, accrochée sur un rebord 15 du récipient 10. Pour imprégner le rouleau 30, l'utilisateur commence généralement par immerger le rouleau 30 sur un tiers de sa périphérie, puis, en le faisant rouler sur la grille 20, lui fait effectuer un tiers de tour, et recommence deux fois de suite ces opérations, en décalant à chaque fois le rouleau d'un tiers de tour avant de l'immerger. L'imprégnation correcte du rouleau requiert ainsi des temps de main d'oeuvre importants, et rien ne garantit l'utilisateur contre le risque d'immerger trop profondément le rouleau 30, ce qui entraînerait une pénétration de peinture dans l'espace intérieur au rouleau, avec pour inconvénient de nécessiter une durée d'essorage prolongée.It is known, to impregnate an application tool such as a brush or a roller, to arrange the paint in a container and to provide the latter with a grid, hung on a rim of said container, for wringing out the tool. application after immersing it in the paint. Such a device according to the prior art is shown by way of illustration in FIG. 1, where we can see the container 10 containing the paint P and the grid 20, hung on a rim 15 of the container 10. To impregnate the roller 30, the user generally begins by immersing the roller 30 on a third of its periphery, then, by rolling it on the grid 20, makes it perform a third of a turn, and repeats these operations twice in succession, shifting to each time the roller a third of a turn before submerging it. Correct impregnation of the roller thus requires significant labor time, and nothing guarantees the user against the risk of immersing the roller 30 too deeply, which would cause penetration of paint into the interior space of the roller. , with the disadvantage of requiring an extended spin time.

On a proposé dans la publication US-A-2 994 901 un dispositif pour imprégner d'un agent de traitement liquide un tampon applicateur, comprenant un récipient pour contenir le liquide et une grille d'imprégnation flottant à la surface du liquide.There has been proposed in publication US-A-2 994 901 a device for impregnating with a liquid treatment agent an applicator pad, comprising a container for containing the liquid and an impregnation grid floating on the surface of the liquid.

La grille comporte une pluralité de canaux cylindriques au travers desquels est forcé le liquide pour imprégner le tampon lorsque ce dernier appuie sur la grille. Afin d'éviter une imprégnation trop importante du tampon applicateur lorsque celui-ci est appuyé sur la grille, cette dernière est conformée de sorte que le tampon obture les canaux, gênant ainsi le passage du liquide à travers la grille et ralentissant l'enfoncement de cette dernière dans le liquide. Cette solution n'est toutefois pas pleinement satisfaisante et le récipient doit être muni d'un rouleau d'essorage contre lequel est déplacé le tampon imprégné avant l'utilisation.The grid has a plurality of cylindrical channels through which the liquid is forced to impregnate the tampon when the latter presses on the grid. In order to avoid excessive impregnation of the applicator pad when the latter is pressed against the grid, the latter is shaped so that the buffer closes the channels, thus hampering the passage of the liquid through the grid and slowing down the penetration of the latter in the liquid. However, this solution is not entirely satisfactory and the container must be provided with a spin roller against which the impregnated pad is moved before use.

La présente invention a pour objet un dispositif amélioré, remédiant aux inconvénients précités, notamment moins coûteux à réaliser et permettant d'effectuer de manière sûre et rapide une imprégnation correcte de l'outil.The present invention relates to an improved device, overcoming the aforementioned drawbacks, in particular less costly to produce and making it possible to safely and quickly carry out a correct impregnation of the tool.

La présente invention propose pour cela un dispositif pour imprégner de peinture un outil d'application, du type comprenant un récipient pour contenir la peinture et une grille conformée pour flotter à la surface de la peinture en étant susceptible de s'enfoncer dans celle-ci sous l'action d'une force exercée vers le bas, de façon à présenter au-dessus de la surface supérieure de la grille, propre à servir d'appui à l'outil, l'épaisseur de peinture voulue pour imprégner l'outil, la grille étant conformée de sorte que ladite surface supérieure émerge hors de la peinture en l'absence de l'outil d'application.The present invention therefore provides a device for impregnating an application tool with paint, of the type comprising a container for containing the paint and a shaped grid for floating on the surface of the paint while being capable of sinking into it. under the action of a downward force, so as to present above the upper surface of the grid, suitable for supporting the tool, the thickness of paint desired to impregnate the tool , the grid being shaped so that said upper surface emerges from the paint in the absence of the application tool.

De façon caractéristique, la flottabilité de la grille est suffisante pour que ladite surface supérieure continue à émerger hors de la peinture lorsqu'un ou plusieurs outils d'application reposent par leur poids sur la grille et la grille comporte une pluralité de canaux débouchant sur ladite surface supérieure, l'un au moins desdits canaux présentant une section interne évasée débouchant sur ladite surface supérieure.Typically, the buoyancy of the grid is sufficient for said upper surface to continue to emerge from the paint when one or more application tools rest by their weight on the grid and the grid has a plurality of channels opening onto said grid. upper surface, at least one of said channels having a flared internal section opening onto said upper surface.

Ainsi, à la différence de la solution adoptée dans la publication US-A-2 994 901, visant à éviter une imprégnation en excès du tampon applicateur en ralentissant l'enfoncement de la grille par l'obturation des canaux de cette dernière, la présente invention facilite au contraire le passage de la peinture à travers la grille tout en lui conférant une flottabilité élevée.Thus, unlike the solution adopted in publication US-A-2 994 901, aimed at avoiding excess impregnation of the applicator pad by slowing down the penetration of the grid by closing the channels of the latter, the present On the contrary, the invention facilitates the passage of paint through the grid while giving it high buoyancy.

La présente invention a également pour objet une grille, prise séparément, propre à être utilisée pour former un dispositif conforme à l'invention.The present invention also relates to a grid, taken separately, suitable for being used to form a device according to the invention.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture détaillée qui va suivre d'un mode de réalisation non limitatif de l'invention, et à l'examen du dessin annexé sur lequel : - la figure 1, précédemment décrite, montre un dispositif pour imprégner de peinture un outil d'application, conforme à l'art antérieur,

On aperçoit sur les figures 2, 3 et 4 un dispositif conforme à l'invention, comprenant un récipient 100 propre à contenir de la peinture et une grille 200. Selon une caractéristique de l'invention, la grille 200 présente une surface supérieure 2100 propre à servir d'appui à un outil d'application non représenté sur ces figures. La grille 200 est conformée pour flotter dans le récipient à la surface de la peinture, en étant susceptible de s'enfoncer dans celle-ci sous l'action d'une force exercée vers le bas, de façon à présenter au-dessus de la surface 2100 une épaisseur de peinture voulue pour imprégner l'outil. Dans un souci de clarté, le dispositif a été représenté sur les figures 2, 3 et 4 dans une configuration où le récipient 100 ne contient pas de peinture.We see in Figures 2, 3 and 4 a device according to the invention, comprising a container 100 adapted to contain paint and a grid 200. According to a characteristic of the invention, the grid 200 has a clean upper surface 2100 to serve as a support for an application tool not shown in these figures. The grid 200 is shaped to float in the container on the surface of the paint, being capable of sinking into it under the action of a force exerted downwards, so as to present above the surface 2100 a thickness of paint desired to impregnate the tool. For the sake of clarity, the device has been shown in FIGS. 2, 3 and 4 in a configuration where the container 100 does not contain paint.

On entend dans la présente invention par "peinture" tout produit d'imprégnation ou de traitement en général, sous forme liquide, gélifiée ou pâteuse, c'est-à-dire toutes les sortes de peintures glycérophtaliques ou acryliques, mais aussi les laques, cires, vernis, fongicides, résines, produits d'étanchéité, et autres produits de traitement d'un support ou d'imprégnation.In the present invention, the term "paint" means any impregnation or treatment product in general, in liquid, gelled or pasty form, that is to say all kinds of glycerophthalic or acrylic paints, but also lacquers, waxes, varnishes, fungicides, resins, sealants, and other products for the treatment of a support or impregnation.

On entend par "outil d'application" tout instrument susceptible d'être utilisé pour appliquer la peinture sur un support, c'est-à-dire tous les pinceaux, brosses, applicateurs du type tampons à peindre, rouleaux, etc...The term “application tool” means any instrument capable of being used for applying the paint to a support, that is to say all the paintbrushes, brushes, applicators of the paint pad type, rollers, etc.

Le récipient 100 comprend un fond 105, de préférence plan comme représenté, bordé latéralement par une paroi relevée 110, s'étendant sensiblement à angle droit par rapport au plan du fond 105. Dans l'exemple de réalisation décrit, le récipient 100 à la forme d'un bac parallélépipédique, mais il va de soi que l'on peut proposer d'autres géométries de récipient sans sortir du cadre de l'invention, la paroi relevée 110 pouvant en outre être adaptée à recevoir un couvercle de fermeture non représenté.The container 100 comprises a bottom 105, preferably plane as shown, bordered laterally by a raised wall 110, extending substantially at right angles to the plane of the bottom 105. In the embodiment described, the container 100 at the shape of a rectangular tank, but it goes without saying that it is possible to propose other container geometries without departing from the scope of the invention, the raised wall 110 being able moreover to be adapted to receive a closure cover not shown. .

De préférence, comme représenté, la grille 200 s'étend sur une surface couvrant la presque totalité du fond 105 du récipient 100, et présente un contour externe 2300 épousant le contour interne de la paroi relevée 110 du récipient 100, de sorte que les mouvements possibles pour la grille 200 dans le récipient 100 sont essentiellement des mouvements de translation selon une direction verticale perpendiculaire au plan du fond 105, c'est-à-dire au plan de la vue de dessus de la figure 2.Preferably, as shown, the grid 200 extends over a surface covering almost the entire bottom 105 of the container 100, and has an external contour 2300 matching the internal contour of the raised wall 110 of the container 100, so that the movements possible for the grid 200 in the container 100 are essentially translational movements in a vertical direction perpendicular to the plane of the bottom 105, that is to say to the plane of the top view of FIG. 2.

Bien entendu, dans le cas d'une variante de réalisation où le récipient 100 et la grille 200 présenteraient un contour symétrique de révolution autour d'un axe vertical, la grille serait alors susceptible de tourner autour de cet axe, en plus du mouvement de translation selon la direction verticale précédemment cité.Of course, in the case of an alternative embodiment where the container 100 and the grid 200 would have a symmetrical contour of revolution around a vertical axis, the grid would then be capable of rotating around this axis, in addition to the movement of translation in the above-mentioned vertical direction.

La grille 200 comprend une partie centrale ou semelle 210, délimitée selon son épaisseur supérieurement par la surface 2100, propre à servir d'appui à un outil d'application non représenté, et inférieurement par une surface plane 2110.The grid 200 comprises a central part or sole 210, delimited according to its thickness above by the surface 2100, suitable for serving as a support for an application tool not shown, and below by a flat surface 2110.

Avantageusement, la semelle 210 est bordée sur sa périphérie par une partie renflée 230, de plus grande épaisseur que la semelle 210, destinée notamment à améliorer la flottaison de la grille à la surface de la peinture et à offrir un confort à l'utilisation, en présentant une paroi périphérique 2350 suffisamment relevée au-dessus de la surface supérieure 2100 de façon à éviter une pénétration de peinture par les bords extérieurs de la grille lorsque celle-ci est enfoncée dans la peinture.Advantageously, the sole 210 is bordered on its periphery by a bulged part 230, of greater thickness than the sole 210, intended in particular to improve the flotation of the grid on the surface of the paint and to provide comfort in use, by presenting a peripheral wall 2350 sufficiently raised above the upper surface 2100 so as to avoid penetration of paint by the outer edges of the grid when the latter is pressed into the paint.

La partie renflée 230 comprend quatre portions rectilignes parallèles deux à deux, c'est-à-dire, plus particulièrement, deux premières portions 231 parallèles entre elles et deux autres portions 232 parallèles entre elles, de moindre longueur que les portions 231, disposées perpendiculairement à ces dernières.The bulged portion 230 comprises four rectilinear parallel portions two by two, that is to say, more particularly, the first two portions 231 parallel to each other and two other portions 232 parallel to each other, of shorter length than the portions 231, arranged perpendicularly to the latter.

Selon une caractéristique avantageuse de l'invention, des oreilles de préhension 240 sont prévues sur deux côtés opposés de la grille. De préférence, il s'agit des côtés de la grille selon lesquels s'étendent les deux portions 232 de plus petite longueur.According to an advantageous characteristic of the invention, gripping ears 240 are provided on two opposite sides of the grid. Preferably, these are the sides of the grid along which the two portions 232 of shorter length extend.

Selon l'invention, il est prévu un passage débouchant sur ladite surface supérieure 2100, par lequel la peinture est susceptible de venir recouvrir cette surface lorsque la grille est enfoncée dans la peinture. Ce passage est, comme représenté, constitué par une pluralité de canaux 220 s'étendant à travers l'épaisseur de la semelle et débouchant sur les surfaces supérieure 2100 et inférieure 2110. Ces canaux 220 présentent chacun de préférence une section interne symétrique autour d'un axe vertical, référencé X pour le canal 220 représenté sur la figure 4A, et peuvent présenter des sections internes diverses, circulaires ou polygonales.According to the invention, there is provided a passage opening onto said upper surface 2100, through which the paint is capable of covering this surface when the grid is pressed into the paint. This passage is, as shown, constituted by a plurality of channels 220 extending through the thickness of the sole and opening onto the upper 2100 and lower 2110 surfaces. These channels 220 each preferably have a symmetrical internal section around a vertical axis, referenced X for the channel 220 shown in FIG. 4A, and can have various internal sections, circular or polygonal.

Conformément à une caractéristique de l'invention, les canaux 220 présentent une section généralement évasée vers le haut, débouchant sur la surface supérieure 2100, de façon à faciliter l'écoulement de la peinture, et selon une autre caractéristique de l'invention, la grille 200 est conformée de sorte que la surface supérieure 2100 continue à émerger hors de la peinture lorsqu'un ou plusieurs outils d'application 30 reposent par leur poids sur la grille 200.According to a characteristic of the invention, the channels 220 have a generally flared upward section, opening onto the upper surface 2100, so as to facilitate the flow of the paint, and according to another characteristic of the invention, the grid 200 is shaped so that the upper surface 2100 continues to emerge from the paint when one or more application tools 30 rest by their weight on grid 200.

Plus particulièrement, comme représenté sur la figure 4A, les canaux 220 comprennent une partie inférieure 221 s'étendant depuis la face inférieure 2110 vers le haut, sur environ les 7/8 de l'épaisseur de la semelle 210, présentant une surface interne tronconique divergeant depuis la surface inférieure 2110, d'un angle voisin de quelques degrés, environ 5° dans l'exemple de réalisation décrit, se prolongeant vers le haut par une fraisure 222 débouchant sur la surface supérieure 2100.More particularly, as shown in FIG. 4A, the channels 220 comprise a lower part 221 extending from the lower face 2110 upwards, over approximately 7/8 of the thickness of the sole 210, having a frustoconical internal surface diverging from the lower surface 2110, by an angle close to a few degrees, approximately 5 ° in the example of embodiment described, extending upwards by a countersink 222 leading to the upper surface 2100.

La géométrie des fraisures 222 a été, dans l'exemple de réalisation décrit, choisie circulaire dans un souci de simplification de l'usinage des moules utilisés pour la réalisation de la grille mais on peut avantageusement proposer de réaliser les fraisures 222 avec une géométrie carrée, ce qui permettrait de réduire les portions de la surface supérieure 2100 servant de surface d'appui pour l'outil d'application entre les fraisures 222, donc d'améliorer le retrait de la peinture en augmentant la section de passage pour la peinture.The geometry of the countersinks 222 has been, in the embodiment described, chosen circular in order to simplify the machining of the molds used for the production of the grid, but it is advantageously possible to propose making the countersinks 222 with a geometry square, which would make it possible to reduce the portions of the upper surface 2100 serving as a bearing surface for the application tool between the millings 222, therefore to improve the paint shrinkage by increasing the passage section for the paint .

La surface inférieure 2110 de la grille 200 est avantageusement conformée pour épouser la forme du fond 105 du récipient 100, de façon à réduire au minimum le volume de peinture restant dans le récipient lorsque la grille repose sur le fond et n'est plus utilisable, avec pour avantage de permettre, lorsque la grille est enlevée, une reprise du travail dans les mêmes conditions que celles obtenues par l'usage de la grille, c'est-à-dire avec une faible épaisseur de peinture pour imprégner l'outil d'application.The lower surface 2110 of the grid 200 is advantageously shaped to match the shape of the bottom 105 of the container 100, so as to minimize the volume of paint remaining in the container when the grid rests on the bottom and is no longer usable, with the advantage of allowing, when the grid is removed, a resumption of work under the same conditions as those obtained by the use of the grid, that is to say with a small thickness of paint to impregnate the tool d 'application.

L'utilisation d'un dispositif conforme à l'invention va être décrite en référence aux figures 5 à 7.The use of a device according to the invention will be described with reference to Figures 5 to 7.

Comme représenté sur la figure 5, la grille est conformée de telle sorte que la surface supérieure 2100 émerge hors de la peinture P en l'absence de l'outil d'application. Le niveau N₁ du plan de la surface supérieure 2100, mesuré en prenant pour référence le plan du fond 105 du récipient 100, est alors supérieur au niveau N₂ de la surface de la peinture P dans le récipient.As shown in Figure 5, the grid is shaped so that the upper surface 2100 emerges from the paint P in the absence of the application tool. The level N₁ of the plane of the upper surface 2100, measured by taking as a reference the plane of the bottom 105 of the container 100, is then greater than the level N₂ of the surface of the paint P in the container.

Selon les caractéristiques physiques de densité, viscosité, tension superficielle, etc... de la peinture, l'homme du métier choisira le matériau dans lequel la grille est réalisée, de sorte que la poussée d'Archimède dûe au volume de matériau immergé soit suffisante pour maintenir la surface supérieure 2100 émergée.According to the physical characteristics of density, viscosity, surface tension, etc. of the paint, the skilled person will choose the material in which the grid is made, so that the Archimedes thrust due to the volume of material immersed is sufficient to maintain the upper surface 2100 emerged.

Avantageusement, la grille couvre une majeure partie de la surface libre de la peinture dans le récipient, de préférence plus des trois quarts, ce qui permet de réduire la surface de peinture au contact direct de l'air ambiant, donc limite les pertes de solvant par évaporation et permet ainsi une meilleure conservation de la peinture.Advantageously, the grid covers a major part of the free surface of the paint in the container, preferably more than three quarters, which makes it possible to reduce the surface of paint in direct contact with the ambient air, thus limiting the losses of solvent. by evaporation and thus allows better conservation of the paint.

La grille 200 peut être réalisée par injection de mousse plastique dans un moule ou par assemblage hermétique de deux demi-coques creuses, l'air emprisonné entre les coques assurant alors la flottabilité de la grille.The grid 200 can be produced by injecting plastic foam into a mold or by hermetically assembling two hollow half-shells, the air trapped between the shells then ensuring the buoyancy of the grid.

De préférence, la grille est réalisée par injection de mousse de polyuréthane dans un moule.Preferably, the grid is produced by injecting polyurethane foam into a mold.

La répartition géométrique du volume de matériau nécessaire pour assurer la flottabilité de la grille s'effectue au choix de l'homme de métier, dans l'épaisseur de la semelle 210 et la partie renflée 230, de façon à conférer à la grille la plus grande stabilité possible à la surface de la peinture lorsqu'une force dirigée vers le bas, appliquée près d'un bord de la grille, tend à déséquilibrer celle-ci.The geometrical distribution of the volume of material necessary to ensure the buoyancy of the grid is carried out at the choice of the skilled person, in the thickness of the sole 210 and the bulged part 230, so as to give the grid the most great stability possible on the surface of the paint when a downward force, applied near an edge of the grid, tends to unbalance it.

On cherchera également, de préférence, à conférer à la grille une rigidité suffisante pour assurer une distribution régulière de peinture quel que soit le point d'application de la force exercée vers le bas.It will also preferably be sought to give the grid sufficient rigidity to ensure a regular distribution of paint whatever the point of application of the force exerted downwards.

On a représenté à titre d'illustration sur la figure 6 un rouleau 30 qui repose par son poids sur la surface supérieure 2100 en restant hors de la peinture P.Illustrated in Figure 6 is a roller 30 which rests by its weight on the upper surface 2100 while remaining out of the paint P.

Conformément à une caractéristique de l'invention, la grille 200 est susceptible de s'enfoncer dans la peinture P sous l'action d'une force F exercée vers le bas, de façon à présenter, au-dessus de la surface supérieure 2100, une épaisseur de peinture N₂-N₁ voulue pour imprégner l'outil d'application.In accordance with a characteristic of the invention, the grid 200 is capable of sinking into the paint P under the action of a force F exerted downwards, so as to present, above the upper surface 2100, a thickness of paint N₂-N₁ desired to impregnate the application tool.

L'expression "épaisseur de peinture voulue" doit être comprise, dans le cadre de la présente invention, comme l'épaisseur de peinture qui procure à l'utilisateur un confort d'utilisation optimal, c'est-à-dire lui permet d'imprégner l'outil d'application d'une quantité adéquate de peinture. Dans le cas de l'exemple d'un rouleau 30, représenté sur la figure 7, on préfère n'imprégner que la partie périphérique 31 du rouleau 30, généralement en mousse ou en fibres, en évitant de faire pénétrer de la peinture dans l'espace intérieur 32 au mandrin du rouleau 30.The expression "desired thickness of paint" should be understood, within the context of the present invention, as the thickness of paint which provides the user with optimal comfort of use, that is to say, allows him to '' soak the application tool with an adequate amount of paint. In the case of the example of a roller 30, represented in FIG. 7, it is preferred to impregnate only the peripheral part 31 of the roller 30, generally made of foam or fibers, avoiding getting paint into the interior space 32 to the mandrel of the roller 30.

Ainsi, dans le cas de l'exemple présenté sur la figure 7, la force F exercée sera telle que l'épaisseur de peinture N₂-N₁ reste inférieure à l'épaisseur de la partie périphérique 31 du rouleau.Thus, in the case of the example presented in FIG. 7, the force F exerted will be such that the thickness of paint N₂-N₁ remains less than the thickness of the peripheral part 31 of the roller.

La section interne des canaux 220 est, comme cela a été précédemment mentionné, évasée, débouchant sur la surface supérieure, facilitant un retrait rapide de la peinture depuis la surface supérieure 2100 lorsque l'outil d'application est retiré, c'est-à-dire lorsque la surface supérieure 2100 tend à émerger hors de la peinture.The internal section of the channels 220 is, as previously mentioned, flared, opening onto the upper surface, facilitating rapid removal of the paint from the upper surface 2100 when the application tool is removed, i.e. -to say when the upper surface 2100 tends to emerge from the paint.

La section interne des canaux 220 est adaptée, au choix de l'homme du métier, aux caractéristiques de viscosité et de tension superficielle de la peinture, de sorte que la perte de charge rencontrée par la peinture à la traversée des canaux 220 ne constitue pas une gêne pour l'utilisateur en limitant trop le débit de peinture.The internal section of the channels 220 is adapted, at the choice of a person skilled in the art, to the viscosity and surface tension characteristics of the paint, so that the pressure drop encountered by the paint when crossing the channels 220 does not constitute discomfort for the user by limiting the paint flow too much.

De préférence, on choisira une section interne présentant une géométrie permettant de couvrir, à l'aide d'un seul modèle de grille, une gamme de viscosités de peintures la plus large possible.Preferably, an internal section will be chosen having a geometry making it possible to cover, using a single grid model, a range of paint viscosities as wide as possible.

Finalement, un dispositif selon l'invention pour imprégner de peinture un outil d'application, grâce à sa structure particulièrement simple, s'avère robuste dans son utilisation, et permet une meilleure conservation de la peinture, des économies de solvant ainsi que des gains de temps de main d'oeuvre en permettant l'imprégnation rapide de l'outil d'application avec la quantité de peinture juste nécessaire.Finally, a device according to the invention for impregnating an application tool with paint, thanks to its particularly simple structure, proves to be robust in its use, and allows better conservation of the paint, savings in solvent as well as gains. of labor time allowing rapid impregnation of the application tool with the quantity of paint just necessary.
