Description

  The present invention relates to a painting roller capable of forming a spotted pattern on a painted surface using a paint, and a painting method using the painting roller.

  2. Description of the Related Art Conventionally, many coating rollers are known that can form irregularities on the outer peripheral surface and can form various spots on the painted surface depending on the shape of the irregularities. Roughly speaking, there are two methods for forming irregularities that can form a spotted pattern. One is to directly process the outer peripheral surface of the roller body with the paint adhesion layer on the outer peripheral surface to form irregularities on the paint adhesion layer itself. The other is to form irregularities by mounting another member on the outer peripheral surface of the roller body.

  For example, Patent Document 1 and Patent Document 2 are examples of forming irregularities by directly processing the paint adhesion layer itself. Patent Document 1 describes a coating roller capable of processing a paint adhesion layer made of a polymer material into a concavo-convex shape and forming a spotted pattern on the painted surface by the concavo-convex shape. In Patent Document 2, a coating roller having a paint adhering layer made of napped fibers is immersed in water, bubbles are generated in the water, and the water temperature is raised while allowing the bubbles to pass through the paint adhering layer. And after raising to the temperature where napped fibers show adhesiveness, napped fibers are made to adhere, water temperature is lowered after that. Thereby, a recessed part is formed in the part in which the bubble entered, and the part where the napped fibers are bonded and hardened is formed as a protruding part.

  On the other hand, there are Patent Documents 3 to 5 as coating rollers for forming irregularities on the outer peripheral surface by attaching another member to the outer peripheral surface of the roller body. In Patent Document 3, a large number of male locking portions are provided on the outer peripheral surface of the roller body. In addition, a surface material having a female locking portion on the back surface is placed on the outer peripheral surface of the roller body, and both are engaged with each other. The surface material floats from the outer peripheral surface of the roller body and has a protruding configuration, so that the paint adheres only to the surface material. For this reason, the shape of the pattern to be painted depends on the shape of the surface material. That is, the pattern to be painted can be changed by changing the shape of the surface material. Patent Document 4 describes a painting roller in which a net is placed on the outer peripheral surface of a roller body. Here, the net has a thread part and a gap surrounded by the thread part. However, in Patent Document 4, the paint does not adhere to the gap part, and the paint adheres to the mesh part (thread part), and the mesh is The shape to be created is painted as a spotted pattern. Patent Document 5 describes, in addition to means for covering the outer peripheral surface of the roller body with a net, similarly to Patent Document 4, a form of covering the outer peripheral surface of the roller body with a cylindrical member having a large number of through holes in the peripheral wall. When the cylindrical member is used, the paint does not adhere to the through-hole portion (concave portion), and the paint is attached to the peripheral wall to form a spotted pattern.

Japanese Patent No. 5626671 JP 2005-288275 A JP 2005-118665 A JP 2005-52700 A JP-A-11-207245

  The coating rollers disclosed in Patent Documents 1 and 2 form irregularities directly on the outer peripheral surface of the roller body, that is, the paint adhesion layer itself. In this case, a special manufacturing process must be performed in order to form the unevenness, and there is a problem in productivity. Moreover, in order to form various spots, it is necessary to prepare a plurality of types of coating rollers having different concavo-convex shapes, which lacks versatility. Since the roller for painting in Patent Document 3 is also provided with a male locking portion on the outer peripheral surface of the roller body and also uses a special surface material, there is a problem in productivity as in Patent Documents 1 and 2. . In addition, since it is necessary to mount a large number of surface materials on the outer peripheral surface of the roller body in order to form a spotted pattern, the number of parts is large and the assembling work becomes complicated.

  On the other hand, when the net is put on the outer peripheral surface of the roller main body as in Patent Document 4, if the net of the net is too large, the paint adheres to the roller main body at the gap portion during coating, and the spotted pattern is crushed. There is a fear. On the other hand, even if the mesh of the net is too small, there is a possibility that when the coating is applied, a coating film is applied to the gap due to surface tension, and the spotted pattern is crushed. As described above, when the unevenness is formed by the net, there is a problem in that there is a great restriction on the mesh shape and it is difficult to form a clear spotted pattern.

  Moreover, even when attaching the cylindrical member which has many through-holes in a surrounding wall like patent document 5, the coating material is made to adhere to the surrounding wall of a cylindrical member to the last, and it does not paint in a through-hole part (concave part). Therefore, as in the case of the net, there is a problem that it is difficult to form a clear spotted pattern if the through hole is too large or too small. In addition, since the paint is attached to the cylindrical member itself, the cylindrical member needs to be formed of a material that is familiar with the paint. Therefore, the cylindrical member cannot be basically a resin molded product that is not familiar with the paint, and there is a problem in the productivity of the cylindrical member.

  Therefore, the present invention is to solve the above-described problems, and an object of the present invention is to provide a painting roller that is highly productive and can easily form various spots.

  As means for that purpose, the painting roller of the present invention has a roller body provided with a paint adhesion layer on the outer peripheral surface, and a cylindrical member covering the roller body. The cylindrical member has a plurality of through holes on its peripheral wall, and a paint adhesion layer protrudes from the through holes to form a brush portion.

  Moreover, according to this invention, the coating method which forms a spot pattern using the said roller for coating can also be provided.

  Since the roller for painting of the present invention only covers the roller body with a cylindrical member having a plurality of through holes, it can easily form an uneven shape. At this time, it is a paint adhesion layer (brush part) of the roller main body which protruded from the through-hole that forms a patch pattern, and a cylindrical member does not apply a paint. Therefore, the material for forming the cylindrical member is not particularly limited. Therefore, it is also possible to manufacture a cylindrical member by injection molding with high productivity. Furthermore, since the spot pattern is formed by the brush portion protruding from the through hole, various spot patterns having a high degree of freedom such as the number, size, and shape of the through holes of the cylindrical member can be clearly formed. . Moreover, since a different spot pattern can be formed simply by exchanging cylindrical members having different through-hole shapes, the versatility is also high. In addition, since a large number of irregularities can be easily formed by simply covering the roller body with the cylindrical member, the assembling operation is also simple.

It is a perspective view of the roller for painting. It is a disassembled perspective view of the roller for painting. It is a sectional side view of the state which is painting the paint using the roller for painting. It is a front view of the state which is painting the paint using the roller for painting. It is a disassembled perspective view of the modification of the roller for painting.

  Hereinafter, representative embodiments of the present invention will be described. As shown in FIGS. 1 and 2, the painting roller 1 includes a roller body 2 having a paint adhesion layer 21 on the outer peripheral surface, a cylindrical member 3 that covers the outer surface of the roller body 2, and a roller body 2 that is rotatable about the roller body 2. A support bar 4 to be supported and a handle 5 provided at the rear end of the support bar 4 are provided.

  As the roller body 2, a conventionally known general coating roller such as a solid coating of paint can be widely used. The core material 20 that serves as the rotating shaft of the roller body 2 and the paint adhesion that impregnates or adheres the paint. Layer 21. That is, it is not necessary to use a special roller body for the formation of spotted patterns.

  The core member 20 has a cylindrical shape, and the support bar 4 is rotatably inserted into a hole provided in the central axis thereof. The core material 20 only needs to have a shape-retaining property (rigidity) such that the entire roller body 2 is not deformed when a paint is applied, and is typically made of a synthetic resin.

  The paint adhesion layer 21 is provided with a constant thickness so as to cover the entire outer peripheral surface of the core member 20. As the paint adhesion layer 21, a known one that has been conventionally used in general coating rollers can be used. That is, it is not necessary to use a special material such as uneven processing of the surface for forming a spotted pattern or a special material. However, in order to accurately form the brush portion as will be described later, one having a certain degree of flexibility or elasticity is preferable. Typically, in addition to fiber materials such as napped fibers and spongy fibers, foamed resins can be suitably used. Also, it can be a (non-foamed) polymer material such as soft rubber or elastomer. The paint adhesion layer 21 can be fixed by flocking the core material 20 in the case of napped fibers and adhering to the core material 20 in the case of other materials.

  The cylindrical member 3 is a cylindrical member having the same axial length as the roller body 2. The cylindrical member 3 has an inner diameter at a position of 30 to 80%, preferably 40 to 70%, more preferably 50 to 60% of the thickness of the paint adhesion layer 21 when the cylindrical member 3 is placed on the roller body 2. And With an inner diameter such that the cylindrical member 3 is present on the inner side of 30% of the thickness of the paint adhesion layer 21, it is difficult to smoothly cover the cylindrical member 3 on the roller body 2, or the paint adhesion layer 21 or the cylindrical shape. The member 3 may be damaged. On the other hand, if the inner diameter is such that the cylindrical member 3 exists outside 80% of the thickness of the paint adhesion layer 21, the amount of protrusion of the paint adhesion layer 21 is small, and there is a high possibility that a clear spot pattern cannot be formed. When the cylindrical member 3 is placed on the roller body 2 and the inner diameter is at a position of 50 to 60% of the thickness of the paint adhesion layer 21, the cylindrical member 3 can be mounted smoothly and clearly. It is easy to achieve both pattern formation. In addition, the position of OO% of the thickness of the paint adhesion layer 21 starts from the core material 20 side. That is, the innermost layer of the paint adhesion layer 21 is a position where the thickness is 0%, and the outermost layer of the paint adhesion layer 21 is a position where the thickness is 100%.

  Since the cylindrical member 3 is not a part where paint is applied, the material is not particularly limited in relation to the paint. Therefore, the material can easily be applied with the paint, but it is more preferable that the material repels the paint (unfamiliar). It is because it is easy to avoid being painted with the cylindrical member 3 unintentionally. Examples of the material that repels paint include water-repellent if the paint is water-based, and oil-repellent if it is organic. The water repellency or oil repellency can be ensured by the material itself, or by forming a fine uneven shape on the surface of the peripheral wall of the cylindrical member 3 to provide a lotus effect (an effect of repelling water and oil by the fine unevenness). It can also be used. On the other hand, the cylindrical member 3 needs to have a shape retaining property (rigidity) that is not greatly deformed by the pressing force (reaction force) from the paint adhesion layer 21. This is because if the cylindrical member 3 comes into contact with the coating surface and the spotted pattern is crushed if it is greatly deformed by the pressing force (reaction force) from the paint adhesion layer 21. The cylindrical member 3 is preferably made of a synthetic resin such as polypropylene or polyethylene in that it is difficult to become familiar with the paint and has a certain shape retaining property and can be produced at low cost by injection molding or the like.

  In addition, a plurality of through holes 3 a are formed in the peripheral wall of the cylindrical member 3. The shape of the through hole 3a is not particularly limited, and various shapes such as a circle, an ellipse, a polygon such as a triangle or a quadrangle, or an indefinite shape can be selected. Furthermore, it is also possible to make a shape with high design such as an animal footprint, a face outline, or a heart shape. The through holes 3a may all have the same shape or may be different from each other.

  Although the number and size of the through-holes 3a can be arbitrarily set, it is preferable that the through-holes 3a exist uniformly over the entire surface in order to avoid the cylindrical member 3 from contacting the surface to be coated. If the through-hole 3a is enlarged, the number may be at least two. On the other hand, a plurality of relatively small through holes 3a can be provided. Moreover, it is preferable that the through-hole 3a is formed in at least one end or both ends of the cylindrical member 3. Thereby, the opening of the end surface of the cylindrical member 3 is expanded, and the roller body 2 can be easily inserted from the end of the cylindrical member 3.

  The support bar 4 is installed between the roller body 2 and the handle 5, bypasses the outside from one end of the roller body 2, and the handle 5 is separated from the roller body 2 by a certain distance in the axial center. It is bent and formed in such a shape as to be located at the part. The support bar 4 only needs to have sufficient rigidity to allow the painting operation to be performed smoothly. Typically, the support bar 4 may be made of metal with high workability, but may be made of synthetic resin or wood. The handle 5 may be a well-known one as long as it has a shape and material that are easy to grip.

  In order to cover the roller body 2 with the cylindrical member 3, as shown in FIG. 2, it is only necessary to push the roller body 2 through the one end opening of the cylindrical member 3 and insert it into the cylindrical member 3. At this time, since the inner diameter of the cylindrical member 3 is smaller than the outer diameter of the roller body 2, the paint adhesion layer 21 protrudes from the through hole 3 a of the cylindrical member 3 as well shown in FIG. 3. The paint adhesion layer 21 protruding from the through hole 3a constitutes the brush portion D.

  When the paint is applied to the predetermined paint surface S by the paint roller 1, as shown in FIGS. 3 and 4, the paint is impregnated or adhered to the roller body 2 in the same manner as a general paint roller. In addition, the roller body 2 may be rotated along the coating surface S. At this time, since the roller body 2 is covered with the cylindrical member 3 having a smaller diameter, only the paint adhesion layer 21 (the brush portion D) protruding from the through hole 3a comes into contact with the coating surface S. Thereby, the spot pattern which exhibits the independent island pattern which the coating materials P mutually spaced apart is formed.

  Although the spotted pattern can be directly formed on the painted surface S, before the spotted pattern is formed, a base coat is applied to completely paint the painted surface S with a predetermined color, and then the overcoat is applied. It is also preferable. If the base coat is applied, the design of the painted surface S is improved. Different spot patterns can be overcoated. When changing the spotted pattern, the cylindrical member may be replaced.

(Modification)
As mentioned above, although typical embodiment of this invention was described, it is not restricted only to this, A various deformation | transformation is possible in the range which does not deviate from the summary of this invention. For example, in the above-described embodiment, the cylindrical member is an integrally molded product, but it includes a plurality of pieces divided in the axial direction, and these can be combined to form a cylindrical shape. Or as shown in FIG. 5, it can also be set as the structure expand | deployed in the circumferential direction centering on a part of surrounding wall of the cylindrical member 7. As shown in FIG. In this case, it can be fixed by covering the roller body 2 with the tubular member 7 being unfolded and engaging the engaging claw 7b and the engaging hole 7c provided on the divided edge portion. According to this modification, it is not necessary to push the roller main body 2 through the one end opening of the cylindrical member 7, so that the mounting operation of the cylindrical member 7 is easy. Therefore, the through-hole 7a does not necessarily have to be formed so as to extend over the end in the axial direction.
