Description

Technical Field

[0001] The present invention relates to a brush suitable for painting work on wall wallpapers, and cleaning work for removing dirt on the outer surface of automobile bodies, boards, ceilings, etc.

Background Art

[0002] Patent Document 1 discloses a painting brush. This painting brush includes a long rectangular base body composed of a first substrate and a second substrate laminated on the first substrate, a hair layer body formed by densely implanting a plurality of short hairs fixed to the second substrate, and a gripping body that movably holds the first substrate. Since the length of the hair layer body is, for example, as large as 400 mm in the form of a long rectangle, a wide wall surface can be easily painted and the workability is good.

[0003] The base body is formed by laminating a second substrate made of a foamed resin having deformable cushioning properties such as urethane foam or cellulose foam on the back surface of the first substrate made of plastic or a metal plate. The thickness of the second substrate is, for example, 5 to 12 mm. The plurality of hairs are fixed to the back surface of the second substrate in a dense state by bundling chemical fibers having a length of, for example, 5 to 8 mm and having durability such as polypropylene.

[0004] The gripping body has a short rectangular base having substantially the same width as the first substrate and a size of about 1 / 3 of the length of the first substrate, and a grip spanned between two columns erected from the base. The base is sandwiched between the long side edge portions on both sides of the first substrate and a pair of guide ribs extending in a state of being folded back to the surface side from each long side edge portion, and is guided to be movable in the longitudinal direction of the first substrate.

[0005] In the painting brush, since the gripping body is movable in the length direction of the first substrate, during the painting work, when the gripping body is positioned at the end in the longitudinal direction of the first substrate, compared with when the gripping body is positioned at the center in the longitudinal direction of the first substrate, the operator can paint even at a high position and a far position in the horizontal direction, and a wide painting range can be painted.

Modes for Carrying Out the Invention

[0020] The brush according to the embodiment of the present invention will be described with reference to the drawings.

[0021] [First Embodiment] Figs. 1 to 3 show a brush according to the first embodiment of the present invention. Fig. 1 shows a brush 1 for a wide-range processing use form which is one form, and it is an assembly of two brush bodies 2 and a gripping body 8. Fig. 2 shows a brush 1' for a sandwich-range processing use form which is another form, and it is an assembly of one brush body 2 and a gripping body 8. The brush body 2 is a laminate, and the gripping body 8 is a molded body made of resin or metal.

[0022] The brush body 2 is formed by adhesively bonding a first substrate 3, a second substrate 4, and a hair layer body 5 in this order in a laminated state. When viewed in the lamination direction, the size is specifically a short rectangle having a size of, for example, 200 to 250 mm in length × 100 to 130 mm in width.

[0023] The first substrate 3 is made of, for example, a resin plate or a metal plate having a thickness of 1 to 3 mm and having planar rigidity.

[0024] The second substrate 4 is made of, for example, a foamed resin such as urethane foam or cellulose foam having a thickness of 7 to 12 mm, that is, a so-called sponge, and has a cushioning property that can be deformed (pushed in) following the uneven shape of the wallpaper on the surface to be treated (painted surface).

[0025] The hair layer body 5 is composed of a flocked sheet 6 and a plurality of short hairs 7 having a required length that are implanted in a dense state on one side of the flocked sheet 6 so as to easily hold the paint by capillary action. The flocked sheet 6 is made of chemical fibers such as polypropylene or polyester fibers or natural fibers such as animal hairs. The short hairs 7 have a length of, for example, 5 to 10 mm and have a required buckling strength. The base ends are adhered to the second substrate 4 by the flocked sheet 6, and the hair tips are free ends and are in a flat plane so that uneven coating does not occur. As shown in Fig. 3, the side surface on the long side of the short rectangle of the hair layer body 5 is preferably beveled, and the side surface on the short side of the short rectangle is preferably rounded (not shown).

[0026] The gripping body 8 is a resin molded body having a base 9 in the shape of a short rectangular plate of a required size, two pillar portions 10 erected from the base 9, and a grip 11 spanned between the two pillar portions 10. The base 9 has, for example, a thickness of 3 to 5 mm and planar rigidity. In a state where the end faces of the laminated surfaces of the two brush bodies 2 corresponding to the short sides of the short rectangle are in close contact and the two first substrates 3 are in one plane and the two hair layer bodies 5 are in one plane, one half is overlapped on the surface of the first substrate 3 of one brush body 2 and the other half is overlapped on the surface of the first substrate 3 of the other brush body 2. The grip 11 has a cylindrical outer surface of a size that is easy to hold, and may be a square tubular outer surface or the like. The interval between the two support portions 10 is, for example, 120 to 130 mm.

[0027] The brush 1 is provided with fixing means (12, 15) for detachably fixing between the first substrate 3 of one brush body 2 where each half of the base 9 of the gripping body 8 overlaps.
