Definitions

  • the present invention relates to a painting device used for obtaining a particular decoration on a surface.
  • Spray painting uses a compressor and a spray gun to apply the paint on the wall, without direct contact of the spray gun with the wall.
  • the paint is sprayed with a jet of compressed air so as to apply a uniform layer of paint on the wall.
  • Such a technique has some advantages, such as speed of execution, quick drying and low paint consumption, but it does not allow for making any special aesthetic effects of the painted surface.
  • Dabbed painting is characterized by a 'rippled' effect of the surface, which is obtained by using a pad consisting of a sponge support to which a synthetic smooth mohair fabric is applied.
  • the support is attached to a handle that is easy and practical to use and is usually made of plastic or metal.
  • pads are commercially available, each one with a particular pattern. A layer of paint of the chosen color is spread on the wall with a paintbrush; once the layer of paint has dried, the pad is dipped into another paint of the same color, but of a different shade (darker or lighter). Then the wall is dabbed with the pad.
  • Such a technique makes it possible to achieve original results and give a personal touch to the walls with easy execution, low cost and customizable decoration. However, such a technique is somewhat time-consuming.
  • spatula painting uses a metal spatula and involves making several layers to paint a wall.
  • a technique has a great decorative effect, long lead times and high cost. It is a complex technique with great a scenic effect and ideal for classical settings. Thanks to the overlapping of irregular signs and lines and to the presence of glazes and contrasts, spatula painting creates a three-dimensional visual effect. It is a more expensive painting technique than the previous ones, and the user of such a techniques must be experienced and skilled.
  • Scratch effect painting involves applying a first layer of paint with a background color and letting it dry; after that, a second layer of paint is applied over the first layer. Before the second layer of paint dries, a metal trowel is applied on the second layer of paint and is moved from the bottom up, and then from right to left, so as to obtain well-defined lines.
  • the scratch effect on the wall can be customized by using two different types of color: a dark color for the base and a lighter color for the surface paint. In such a way, when making the lines on the walls, not only the scratch effect is obtained, but also the possibility to observe both colors.
  • Such a technique hides any imperfections in the wall, has good durability and low cost. However, this technique is somewhat time-consuming because it involves moving the trowel vertically and then horizontally. Moreover, also this technique requires experience and skill.
  • the purpose of the present invention is to eliminate the drawbacks and limitations of the prior art by providing a painting device that is extremely simple and quick to use and at the same time is capable of repeatedly generating the same patterned design on the painted surface characterized by a texture comprising a shaded irregular set of orthogonal streaks.
  • Another purpose is to provide such a painting device that is practical, versatile, economical, and easy to implement.
  • a painting device is described according to the invention, which is comprehensively denoted with reference numeral 100.
  • the painting device (100) comprises a handle (1) having a substantially cylindrical shape, with an axis (X).
  • the handle (1) is suitable for being held by an operator.
  • a support rod (2) is attached to the handle (1).
  • the support rod (2) is appropriately bent.
  • the support rod (2) comprises:
  • a cylindrical roller (6) is rotatably mounted on the fourth section (23) of the support rod, so as to rotate about an axis of rotation (Y) orthogonal to the axis (X) of the handle.
  • the roller (6) has a length such that the axis (X) of the handle (1) passes through the center of the roller (6).
  • the roller (6) can be made in one piece.
  • the roller (6) may comprise a support core (3) rotatably mounted on the fourth section (23) of the support rod and a tubular sleeve (4) mounted on the support core (3), so as to rotate integrally with the support core (3).
  • Fig. 4 shows the roller (6) with the tubular sleeve (4) mounted on the support core (3).
  • the sleeve (4) has an internally hollow cylindrical shape.
  • the sleeve (4) can be fixedly mounted on the support core (3) or can be integral with the support core (3).
  • the handle (1) can be made of plastic or wood.
  • the support rod (2) can be made of metal.
  • the support core (3) can be made of wood or rigid plastic.
  • the sleeve (4) can be made of synthetic rubber, natural rubber, latex or silicone.
  • the peculiarity of the roller (6) is that it comprises a plurality of ribs (51, 52) on its lateral surface (40).
  • Each rib (51, 52) has decreasing dimensions moving away from the longitudinal axis (Y) of the roller (6).
  • each rib (51, 52) has a trapezoidal cross-section with the major base in contact with the lateral surface (40), and has a trapezoidal longitudinal section with the major base in contact with the lateral surface (40).
  • Each rib (51, 52) also has a convex upper surface (50) (shown in Fig. 3 ).
  • the plurality of ribs (51, 52) comprises:
  • Each space (SR) of each row (R) is crossed by one of said transverse ribs (52), whereas each space (SC) of each column (C) is crossed by one of said longitudinal ribs (51).
  • each longitudinal rib (51) crosses the corresponding space (SC) centrally and each transverse rib (52) crosses the corresponding space (SR) centrally.
  • the longitudinal ribs (51) are all equal and the transverse ribs (52) are all equal.
  • each longitudinal rib (51) preferably has the following dimensions:
  • the transverse ribs (52) preferably have the following geometric characteristics:
  • the space (SR) between two longitudinal ribs (51) has a length (QR) lower than the length (L1) of the trapezoidal longitudinal section of the longitudinal rib (51).
  • the space (SC) between two transverse ribs (52) has a length (QC) lower than the length (L2) of the trapezoidal longitudinal section of the transverse rib (52).
  • the space (SR) between two longitudinal ribs (51) has a length (QR) of 1-1.8 cm measured between the major bases of the longitudinal sections of the longitudinal ribs (51).
  • the space (SC) between two transverse ribs (52) has a length (QC) of 1-2 cm measured between the major bases of the longitudinal sections of the transverse ribs (52).
  • Each row (R) is staggered with respect to the adjacent row (R) and each column (C) is staggered with respect to the adjacent column (C).
  • each row (R) is staggered with respect to the adjacent row (R) by a section (TL) equal to half the sum of the length (L1) of the major base of the longitudinal section of the longitudinal rib (51) with the length (QR) of the space (SR) between two longitudinal ribs (51).
  • Each column (C) is staggered with respect to the adjacent column (C) by a circumferential section (TC) equal to half the sum of the length (L2) of the major base of the longitudinal section of the transverse rib (52) with the length (QC) of the space (SC) between two transverse ribs (52).
  • each row (R) is staggered with respect to the adjacent row but is not staggered with respect to the row (R) immediately following the adjacent row.
  • each column (C) is staggered with respect to the adjacent column (C) but is not staggered with respect to the column immediately following the adjacent column (C).
  • a roller (6) having ribs (51, 52) with said specifications and having a length (L) of about 20-35 cm and a diameter (D) of about 6-12 cm, thus a circumference of 19-37 cm.
  • a row (R) comprises 6 to 10 longitudinal ribs (51) and a column (C) comprises 6 to 12 transverse ribs (52).
  • the shape and distribution of the ribs (51, 52) are designed in such a way that the ribs (51, 52) leave imprints on a layer of paint suitable for generating an aesthetic effect composed of orthogonal irregular streaks so as to achieve a particularly attractive patterned texture.
  • the device according to the invention is to be used on surfaces that have been previously painted in the traditional way, such as with a brush, roller, or spray. Then, before the layer of paint dries, the roller (6) of the painting device (100) is rolled over the layer of fresh paint. In this case, the ribs (51, 52) of the roller (6) compress the layer of fresh paint. With reference to Fig. 5 and 5A , the color of the fresh paint is a lighter color than the color of the painted surface.
  • the pressure of the ribs (51, 52) of the roller (6) on the layer of fresh paint generates imprints (7) with an irregular contour on the layer of paint, with a different color shade than the color (8) of the layer of fresh paint that has not been in contact with the ribs (51, 52) of the roller.
  • Such imprints (7) are distributed along staggered rows (R) and columns (C), like the ribs (51, 52) of the roller.
  • the imprints (7) of the layer of paint are lighter than the color (8) of the layer of fresh paint that has not been in contact with the ribs (51, 52) of the roller, since the fresh paint is removed as a result of said contact.
  • irregular vertical and horizontal streaks (9) can be appreciated around the imprints (7) that correspond precisely to the parts where the ribs (51, 52) have removed the fresh paint.
  • the painting device (100) makes it possible to obtain a particularly attractive visual effect that combines the regularity of the distribution of the lines and columns with the irregularity given by the removal of paint by the ribs (51, 52) in an uneven manner.
  • the painting device (100) allows even an inexperienced user to make walls with a patterned texture in a simple and extremely rapid way, by simply running the roller over the fresh paint only along one direction. So the new painting device (100) greatly facilitates the painting operations. In fact, the painting device (100) can be easily used even by inexperienced users who can achieve distinctive and aesthetically appealing results without availing themselves of professional painters, just like those obtained by the ordinary methods of the prior art that are usually used by professional painters.
