Description

La présente invention a pour objet un rouleau pour appliquer un enduit de peinture pour travaux intérieurs sur un support.The present invention relates to a roller for applying a coating of paint for interior work on a support.

Avant d'appliquer un revêtement décoratif, par exemple de la peinture ou un papier peint, sur les murs et plafonds intérieurs, il est préférable voire indispensable de préparer le support afin de rendre lisse la surface à recouvrir.Before applying a decorative coating, for example paint or wallpaper, on interior walls and ceilings, it is better or even essential to prepare the support to smooth the surface to be covered.

Les principaux types d'enduisage sont :

  • le rebouchage pour combler les cavités ou les discontinuités
  • le dégrossissage pour supprimer le bullage et combler les irrégularités
  • le lissage.
The main types of coating are:
  • filling to fill cavities or discontinuities
  • roughing to remove bubbling and fill in irregularities
  • Smoothing

Traditionnellement l'enduisage est réalisé avec des outils à lame métallique qui doivent être soigneusement préparés notamment par affûtage. Les opérations continues de dégrossissage et de lissage exigent une grande dextérité dans le maniement des outils d'enduiseur, un apprentissage est donc nécessaire pour un peintre non formé aux pratiques des enduiseurs.Traditionally coating is achieved with metal blade tools that must be carefully prepared including sharpening. The continuous operations of roughing and smoothing require a great dexterity in the handling of the tools of coater, a learning is thus necessary for a painter not trained to the practices of coaters.

La présente demande se propose de faciliter et rendre moins pénibles les travaux d'enduisage des murs et plafonds et d'en augmenter notablement le rendement en fournissant un outil dont l'usage est simple et efficace.The present application proposes to facilitate and make less painful the coating work of walls and ceilings and significantly increase the yield by providing a tool whose use is simple and effective.

Plus particulièrement, l'outil est un rouleau permettant l'application d'enduits de peinture pour travaux intérieurs sur tous supports et principalement sur les supports très irréguliers et/ou à fort relief. De préférence, l'enduit de peinture pour travaux intérieurs déposé à l'aide du rouleau de l'invention est ensuite égalisé, uniformisé et/ou lissé avec une des raclettes objet des demandes déposées le même jour.More particularly, the tool is a roller allowing the application of paint coatings for interior work on all substrates and mainly on very irregular and / or high relief media. Preferably, the paint coating for interior work deposited using the roller of the invention is then equalized, standardized and / or smoothed with one of the squeegees object of the applications filed the same day.

Le rouleau comprend un manche et un cintre, sur lequel est monté un mandrin rigide avec un surmoulage structuré souple.The roller comprises a handle and a hanger, on which is mounted a rigid mandrel with a flexible structured overmoulding.

De préférence, le surmoulage structuré comporte une pluralité de dômes, plus particulièrement les dômes ont la forme de pyramides tronquées à 8 pans.Preferably, the structured overmolding comprises a plurality of domes, more particularly the domes have the shape of 8-sided truncated pyramids.

Selon un mode de réalisation préféré, la base des dômes est constituée par un octogone irrégulier : 4 grands côtés sur les médianes et 4 petits côtés sur les diagonales, les petits côtés ayant une longueur de 2 à 15 mm et les grands côtés ayant une longueur de 4 à 25 mm ; les dômes ont une hauteur de 1 à 4 mm.According to a preferred embodiment, the base of the domes consists of an irregular octagon: 4 long sides on the medians and 4 small sides on the diagonals, the short sides having a length of 2 to 15 mm and the long sides having a length from 4 to 25 mm; the domes have a height of 1 to 4 mm.

La pluralité des dômes est organisée de manière régulière à la surface du surmoulage. Plus particulièrement les dômes sont alignés et disposés en quinconce.The plurality of domes is regularly organized on the surface of the overmoulding. More particularly, the domes are aligned and arranged in staggered rows.

Selon un mode de réalisation particulièrement préféré, le rouleau comporte six rangées de dômes disposés en quinconce, chaque dôme ayant une largeur de 17 mm à la base et une hauteur de 2,6 mm ; les dômes consécutifs ainsi que les lignes consécutives sont espacés d'environ 4 mm. La base des dômes est un octogone dont les côtés sur les médianes ont une longueur d'environ 8,5 mm et les côtés sur les diagonales une longueur d'environ 5,9 mm.According to a particularly preferred embodiment, the roll comprises six rows of domes arranged in staggered rows, each dome having a width of 17 mm at the base and a height of 2.6 mm; the consecutive domes as well as the consecutive lines are spaced about 4 mm apart. The base of the domes is an octagon whose sides on the medians are about 8.5 mm long and the sides on the diagonals about 5.9 mm long.

Le mandrin du rouleau présente une longueur de 100 à 300 mm, plus particulièrement de 180 mm. Le rouleau présente un diamètre de 30 à 70 mm, plus particulièrement de 42 à 48 mm.The mandrel of the roll has a length of 100 to 300 mm, more particularly 180 mm. The roll has a diameter of 30 to 70 mm, more particularly 42 to 48 mm.

Le mandrin rigide est de préférence en matière thermoplastique rigide, par exemple en polypropylène.The rigid mandrel is preferably made of rigid thermoplastic material, for example polypropylene.

Le surmoulage structuré souple est par exemple en polymère souple, de préférence en élastomère thermoplastique souple. Selon un mode de réalisation préféré, l'élastomère thermoplastique souple présente une dureté de 10 à 40 shore A. Plus particulièrement, l'élastomère thermoplastique souple est un copolymère séquencé styrène-éthylène/butylène-styrène ou un mélange EVA/PE (mélange copolymère éthylène-acétate de vinyle et polyéthylène).The flexible structured overmolding is for example flexible polymer, preferably flexible thermoplastic elastomer. According to a preferred embodiment, the flexible thermoplastic elastomer has a hardness of 10 to 40 shore A. More particularly, the flexible thermoplastic elastomer is a styrene-ethylene / butylene-styrene block copolymer or an EVA / PE mixture (copolymer mixture ethylene-vinyl acetate and polyethylene).

Le manche du rouleau est en matière thermoplastique, par exemple en polypropylène. Il permet la manipulation et le guidage du mandrin. De préférence, il présente une ergonomie avancée et il peut être adapté sur une perche télescopique appropriée.The roller handle is made of thermoplastic material, for example polypropylene. It allows the manipulation and guidance of the mandrel. Preferably, it has advanced ergonomics and can be adapted to a suitable telescopic pole.

Le cintre est de préférence en acier galvanisé, il présente un diamètre de quelques millimètres, par exemple de 6,8 mm.The hanger is preferably made of galvanized steel, it has a diameter of a few millimeters, for example 6.8 mm.

Le mandrin est maintenu sur le cintre à l'aide de 2 pièces de liaison : un bouchon butée qui sert de butée au cintre et un bouchon entrée qui enserre une bague frein, qui est une pièce serrante sur le cintre et qui permet la rotation par glissement entre le cintre et le mandrin. Le bouchon entrée assure le guidage du mandrin avec la bague frein. Le bouchon butée et le bouchon entrée sont en matière thermoplastique, par exemple en polypropylène ou en acrylonitrile-butadiène-styrène (ABS). La bague frein est en matière thermoplastique, par exemple en polyformaldéhyde (POM) ou en polyamide 6 (PA6).The mandrel is held on the hanger by means of 2 connecting pieces: a stopper which serves as a stop for the hanger and an inlet plug which encloses a brake ring, which is a tight piece on the hanger and which allows the rotation by sliding between the hanger and the mandrel. The inlet plug guards the mandrel with the brake ring. The abutment plug and the inlet plug are made of thermoplastic material, for example polypropylene or acrylonitrile-butadiene-styrene (ABS). The brake ring is made of thermoplastic material, for example polyformaldehyde (POM) or polyamide 6 (PA6).

Les pièces du rouleau de l'invention, à l'exception du cintre, sont en matière synthétique. Le rouleau n'est pas sensible à l'eau et ne se déforme pas contrairement aux outils traditionnels majoritairement composés de métal et de bois.The roll parts of the invention, with the exception of the hanger, are made of synthetic material. The roller is not sensitive to water and does not deform unlike traditional tools mainly made of metal and wood.

Le rouleau de l'invention est utilisé pour appliquer des enduits de peinture pour travaux intérieurs, de préférence des enduits garnissants. De manière classique, les enduits de peinture pour travaux intérieurs peuvent être des enduits à gâcher avec de l'eau, des enduits en pâte prêts à l'emploi ou des enduits pluri-composants.The roll of the invention is used to apply paint coatings for interior work, preferably filling coatings. Conventionally, interior paint coatings may be plaster for tempering with water, ready-to-use paste coatings or multi-component coatings.

Les enduits en poudre sont par exemple à base de plâtre, de ciment ou de liant organique. Les enduits en pâte sont de préférence à base de liant organique.The powder coatings are for example based on plaster, cement or organic binder. The paste coatings are preferably based on organic binder.

Afin d'obtenir un résultat optimum, le rouleau selon l'invention est utilisé pour appliquer des enduits de peinture pour travaux intérieurs présentant une densité supérieure ou égale à 0,5, une granulométrie inférieure ou égale à 2000 µ et une viscosité comprise entre 100 000 et 500 000 mPa.s (la viscosité est mesurée à l'aide d'un viscosimètre Brookfield RVDV III - Hélipath S96/50 mm - 10 rpm à une température de 20 ± 1°C).In order to obtain an optimum result, the roller according to the invention is used to apply paint coatings for interior work having a density greater than or equal to 0.5, a particle size less than or equal to 2000 μ and a viscosity of between 100. 000 and 500 000 mPa.s (the viscosity is measured using a Brookfield RVDV III viscometer - Helipath S96 / 50 mm - 10 rpm at a temperature of 20 ± 1 ° C).

Le rouleau selon l'invention est préconisé pour des travaux de petites et moyennes surfaces. Il est léger et très maniable, il permet ainsi une application des enduits de peinture pour travaux intérieurs avec un meilleur rendement qu'avec des outils traditionnels, en nécessitant moins d'efforts avec un pouvoir garnissant supérieur et en évitant la majorité des défauts d'enduisage, tels que surépaisseurs, côtes, sardines et arrachements. Le temps passé pour éliminer les éventuels défauts localisés par ponçage est donc également notablement réduit.The roller according to the invention is recommended for work of small and medium surfaces. It is light and very manageable, it allows an application of paint coatings for interior works with a better yield than with traditional tools, requiring less effort with a superior filling power and avoiding the majority of the defects of coatings, such as overthickness, ribs, sardines and tearing. The time spent to eliminate any localized defects by sanding is therefore also significantly reduced.

Le rouleau est prêt à l'emploi, l'ensemble mandrin plus surmoulage peut être facilement remplacé par un ensemble neuf ou par un ensemble d'un autre type, par exemple un ensemble mandrin plus gaine lisse.The roll is ready for use, the over-molded mandrel assembly can be easily replaced by a new assembly or by an assembly of another type, for example a more smooth sheath mandrel assembly.
