Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a painting roller brush used for painting by impregnating a water-absorbing rotating roller with a paint.
[0002]
[Prior art]
Conventionally, it is desirable that a roller of a painting roller brush be able to hold a large amount of paint from the standpoint of improving the efficiency of painting work and preventing the paint from dripping. Many covers are used.
[0003]
However, the roller cover has a rough texture on the surface of the sponge and a raised state of the nap, resulting in insufficient adhesion to the painted surface, and is unsatisfactory in the finish of the painted surface. In addition, since the porosity of the sponge or nap that holds the paint is low, it has a disadvantage that it droops when the concentration of the paint is low, contaminates the surroundings and impairs workability.
[0004]
Japanese Utility Model Laid-Open No. 5-74679 discloses a roller brush for painting, in which a brush surface-constituting fabric made of fibers knitted with super fine yarn is attached to the surface of a roller body that is rotatably attached. This roller brush has high adhesion to the painted surface and extremely high water retention due to the properties of the fibers resulting from the use of ultra-fine yarn, so that a smooth painted surface is obtained, paint dripping is less, The drawbacks of the roller described above are eliminated.
[0005]
[Problems to be solved by the invention]
However, since this roller brush is made by adhering the brush surface constituting cloth material to the circumferential surface of the roller body, there is a seam of the pasted brush surface constituting cloth material. It has the disadvantages that remain.
[0006]
In addition, although the brush surface construction cloth material made of ultra-fine yarn has a high impregnation rate of the paint, the roller of this roller brush applies the cloth material to the roller body (core) formed of paper material or synthetic resin material. The amount of paint held on the roller cover is regulated by the thickness of the cloth material. Therefore, there was a dissatisfaction with the direction in which a larger area was desired by one impregnation operation of the paint.
[0007]
Further, when the brush surface constituting cloth material is worn, the entire roller has to be replaced, which is uneconomical.
[0008]
The present invention has been made in view of the above-described problems, and provides an economical roller brush that can obtain a smooth painted surface without leaving traces of the roller surface and can sufficiently hold the paint on the roller. It is an object.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is knitted in a loop shape with super fine yarn on the surface of a roller body in which a roller cover made of an absorbent pad is wound around a core rotatably attached to a handle. Roller made into a brush surface by detachably covering a tubular fabric body having no seams with super knitted fabric made of ultra-fine fibers so that it does not fall off from the roller body 4 by squeezing the opening portion by tightening straps at both ends. Is formed.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.
[0011]
1 to 7 show an embodiment of a painting brush according to the present invention. As shown in FIG. 1, a handle 20 and a roller 1 rotatably attached to a holder area H of the handle 20 are shown. It consists of and.
[0012]
The handle 20 is a well-known handle, and includes a grip 22, an arm 23, and a holder area H that is formed in an elastic cylindrical shape by a plurality of spring steels (not shown) on the front side of the arm 23. . Reference numeral 21 denotes a bearing cap at the tip of the holder area H.
[0013]
As shown in FIG. 2, the roller 1 detachably fitted in the holder area H in the present embodiment includes a core 2 formed in a cylindrical shape with a synthetic resin material, paper material, or aluminum, and the core 2 A well-known roller cover made up of an absorbent pad 3 made of sponge or pile wound around the circumference of the body is used as the roller body 4, and the seamless tubular cloth body 5 shown in FIG. Configured.
[0014]
The tubular fabric body 5 is mainly made of acrylic, polyester, polyamide, or ultra-fine fibers knitted with very thin yarn of 1 denier (diameter 10 microns) or less by a blend of these, as shown in FIG. In addition, a knit fabric knitted into a loop shape 10 is formed into a seamless and highly stretchable tube made of ultrafine fibers.
[0015]
The stretchable tubular cloth body 5 covered on the roller body 4 is in close contact with the circumferential surface of the roller body 4 and is knitted in a loop shape, so that the fibers are not easily unwound and has a large water holding capacity. It is a cloth tube with a unique feel. Further, the tubular cloth body 5 is detachably fixed so as not to fall off the roller body 4 by squeezing the opening 7 with the fastening strings 6, 6 at both ends thereof.
[0016]
Note that the detachable fixing means of the tubular cloth body 5 is not limited to the figure finger string 6. For example, the opening 7 may be provided with an elastic ring to be squeezed and fixed, or both ends of the tubular cloth body 5 are stretched back and forth so that the opening 7 is inserted into the hole 8 of the core 2 of the roller body 4 to be stopped. You may make it fix to the hole 8 of the core 2 with a stopper (illustration omitted).
[0017]
The roller 1 in the present embodiment impregnates the roller cover 4, which has a large water absorption, with the coating material, and also impregnates the superfine fiber tubular cloth body 5 on the surface of the roller body 4. The ultra-fine fiber made of ultra-fine yarn has a three-dimensional structure with a high porosity, and the impregnation rate is higher than the material of the roller cover, so the impregnation rate of the paint is higher than the conventional roller brush. It has become a thing.
[0018]
Moreover, the tubular cloth body 5 has extremely high retention of the impregnated paint based on the capillary phenomenon produced by the ultrafine yarn. Therefore, even a paint having a low concentration can be held, and the paint impregnated in the entire roller 1 is held without dripping. Therefore, the roller 1 impregnates and retains a large amount of paint by a single dipping operation of the paint, enabling a large area to be coated, and the work is made efficient.
[0019]
In addition, since the tubular cloth body 5 knitted with super fine yarn becomes a brush surface on the painted surface, the roller 1 comes into contact with the painted surface, so that the brush surface is very close and a smooth painted surface is obtained. be able to. In addition, since the tubular cloth body 5 has no seam, no trace of the seam is left on the painted surface, and an extremely high quality finished surface with no trace of the trace of the coating or the roller can be obtained. .
[0020]
Furthermore, the tubular cloth body 5 serving as the brush surface can be easily removed from the roller body 4 by releasing the fixing means. Therefore, when the tubular cloth body 5 is worn, only the tubular cloth body 5 can be replaced, and when it becomes dirty, it can be easily removed and washed.
[0021]
FIG. 5 shows another embodiment, in which a large hard core 2 is used as a roller body 4, and a tubular cloth body 5 is directly coated on the circumferential surface of the core 2 directly.
[0022]
When it is better to use a hard roller in view of the properties of the painted surface and paint, the above-described configuration may be adopted, and a high-quality painted surface that does not leave traces of seams on the painted surface is obtained.
[0023]
6 and 7 show another embodiment, and the same reference numerals are given to the same parts as those described in the drawings, and the description thereof is omitted.
[0024]
The tubular cloth body 4 in the present embodiment is formed by sewing and closing one end portion thereof, and both end surfaces of the roller body are vertical surfaces having a vertical cross section at a right angle. Therefore, by covering the closed side of the tubular cloth body 4 as the tip surface 9 of the roller 1, the tip surface 9 of the roller 1 is a vertical brush surface.
[0025]
The means for closing the end portion of the tubular cloth body 4 is not limited to the sewing means as illustrated because the tip surface 9 of the roller 1 is a brush surface. For example, one end portion of the tubular cloth body 4 may be closed and knitted to form a bag, and appropriate means such as an adhesive means by an adhesive, a fastening means from the inside of the tubular cloth body 4 by a fastening ring or the like may be used. Used.
[0026]
Since the roller brush for painting according to the present embodiment has the tip surface 9 as a brush surface, as shown in FIG. 7, the plane 12 of the coated body 11 and the vertical surface 13 orthogonal to the plane 12 are coated simultaneously. In addition, since the front end surface 9 of the roller 1 is formed with a vertical cross section at a right angle, the corner portion 14 of the coated body, which has been conventionally supplemented by brush coating, can be coated at the same time.
[0027]
【The invention's effect】
The present invention is implemented in the form as described above, and has the following effects.
[0028]
By seamlessly covering the surface of the roller body with a seamless tubular fabric made of ultrafine fibers knitted in a loop with ultrafine yarn, the seamless tubular fabric becomes a brush surface on the painted surface. The contact makes it possible to obtain a very smooth and high-quality finished surface with super fine fibers that do not leave traces of seams.
[0029]
Further, by forming a roller by using a well-known water-absorbing roller cover as a roller body and covering this with a tubular cloth body, the entire roller can be suspended without impregnating with a large amount of paint. Therefore, according to the brush by this roller, it is possible to paint a large area by one dipping operation of the paint, and the painting work is made efficient in addition to the above effects.
[0030]
Moreover, the roller brush for painting according to the present invention can use a ready-made roller cover as a roller body, and therefore can be supplied very easily and inexpensively.
[0031]
In addition, by closing the end surface of the tubular cloth body and making the tip of the roller a vertical brush surface, it is possible to paint both the flat surface of the coated body and the perpendicular surface and its corners at the same time. Significant progress and further efficiency.
[0032]
Conventionally, the roller cover has been completely replaced when the brush surface is worn or damaged, whereas the tubular cloth body that is the brush surface can be easily attached to and detached from the roller body, so if only the tubular cloth body is replaced, Well and economical. Moreover, since the tubular cloth body can be removed and washed, maintenance of the brush surface is easy.
