Definitions

  • the present invention relates to a roller for applying a coating of paint for interior work on a support.
  • a decorative coating for example paint or wallpaper
  • 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.
  • 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.
  • 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.
  • the roller comprises a handle and a hanger, on which is mounted a rigid mandrel with a flexible structured overmoulding.
  • the structured overmolding comprises a plurality of domes, more particularly the domes have the shape of 8-sided truncated pyramids.
  • 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.
  • the plurality of domes is regularly organized on the surface of the overmoulding. More particularly, the domes are aligned and arranged in staggered rows.
  • 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.
  • 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.
  • the rigid mandrel is preferably made of rigid thermoplastic material, for example polypropylene.
  • the flexible structured overmolding is for example flexible polymer, preferably flexible thermoplastic elastomer.
  • 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).
  • 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.
  • the hanger is preferably made of galvanized steel, it has a diameter of a few millimeters, for example 6.8 mm.
  • 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).
  • the roll parts of the invention 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.
  • the roll of the invention is used to apply paint coatings for interior work, preferably filling coatings.
  • interior paint coatings may be plaster for tempering with water, ready-to-use paste coatings or multi-component coatings.
  • the powder coatings are for example based on plaster, cement or organic binder.
  • the paste coatings are preferably based on organic binder.
  • 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 ⁇ 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).
  • 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.
  • 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.
  • the roller according to the invention consists mainly of a handle (1), a hanger (2), a mandrel (3) and a structured overmoulding (4).
  • the mandrel (3) is a smooth cylinder on which is mounted a structured overmoulding (4) of cylindrical shape having on its surface a plurality of domes (8).
  • the domes (8) are in the form of truncated eight-sided pyramids. The domes (8) are aligned and arranged in staggered rows.
  • the roller comprises a stopper (5) and an inlet plug (6) which are connecting pieces holding the mandrel (3) on the hanger (2).
  • the inlet plug (6) encloses a brake ring (7) which is a clamping piece on the hanger and which allows the sliding rotation between the hanger (2) and the mandrel (3).
  • the inlet plug (6) and the brake ring (7) guide the mandrel (3).
  • FIGS. 2 and 3 represent respectively a front view and side view of the structured overmoulding (4) according to the invention.
  • the overmolding comprises 6 rows of domes (8) arranged in staggered rows.
  • Each dome (8) has the shape of a truncated eight-sided pyramid, whose base forms an irregular octagon with 4 long sides on the medians and 4 small sides on the diagonals.
  • the long sides have a length a and the octagon has a total width b .
  • the distance between 2 consecutive domes as well as the distance between 2 rows of domes is equal to c .
  • the height of each dome is equal to h.
  • each dome (8) is slightly rounded forming convex segments.
  • a is 8.5 mm
  • b is 17 mm
  • c is 4 mm
  • h is 2.6 mm.
  • L is the total length of the structured overmoulding (4); preferably it is equal to 180 mm.
