However, with conventional brushes with soft fibers, it is easy to clean light and fine dust, dust, and dust, but there is a problem that heavy and large dust cannot be sufficiently swept away due to the weakness of the fibers. It was.
Further, the soft and soft fibers tend to open the hair bundle immediately and have a problem in durability.
On the other hand, in the case where a brush is formed with a brush made of a synthetic resin fiber that hardens dirt and dust on a soft surface, there is a problem that the surface is damaged.

The present invention has been made in view of the above-described conventional problems, and can easily remove soft and large dust, and sticky dirt that is heavy and dusty. intended to be able to provide a method of manufacturing a brush which can be easily and inexpensively manufactured excellent brush durability.

In order to achieve the above object, a method for manufacturing a brush according to the present invention is premised on a method for manufacturing a brush in which a flocked hole is formed in a pedestal, and a brush member bundle is formed in the flocked hole to form a brush. The brush member bundle is composed of a plurality of brush members having different hardnesses , and a hard brush member of the plurality of brush members having different hardnesses is disposed on the outer periphery of the soft brush member, and is hard. The length of the brush member is shorter than the length of the soft brush member, and the hair is planted. Then, when a plurality of brush members having different hardnesses are folded in half and inserted into the flocking hole and fixed, the hard brush member is gripped by a gripping tool in a state where it is positioned outside the valley, and the planting is folded. It is characterized by being inserted into the pores and fixed .

  According to the method for manufacturing a brush according to the present invention, when a flocking hole is drilled in a pedestal and a brush member bundle is formed in the flocking hole to form a brush, the brush member bundle has a plurality of brush members having different hardnesses. When the plurality of brush members having different hardnesses are folded in half and inserted into the flocking hole and fixed, the hard brush member is disposed so as to be positioned on the outer periphery of the soft brush member and is hard. Since the length of the brush member is shorter than the length of the soft brush member, the hair is planted, so that it can be implemented with a simple structure and at a low cost.

  Further, in the method for manufacturing a brush according to the present invention, the method for manufacturing a brush having the above-described configuration, in which a plurality of brush members having different hardnesses are gripped by a gripping tool, folded in half, inserted into a flocked hole, and fixed. In the state where the brush member is positioned on the outside where the valley is folded, it is gripped by a gripping tool, folded in half, and inserted into the flocking hole and fixed, the existing brush manufacturing apparatus can be used as it is, There is an advantage that the brush can be manufactured at low cost.

Furthermore, the flocking holes drilled in the base, with not hard brush member is implanted so as to be positioned on the outer periphery of the soft brush member, it is made shorter than the length of the rigid brush member of soft length brush member since, and ready to outside protected a rigid brush member of soft, brush member, since not hard to open that tufts of soft, brush member brush member is suppressed, it is possible to increase the durability There are advantages you can

In addition, since the soft Rakai brush member are allowed to protrude from the rigid brush member, by stroking in which dirt and dust is lighter that with a soft surface, together can be performed dust without damaging the surface, in the case of stubborn stains force By inserting and pressing, it is possible to remove stubborn dirt with a hard brush member, and there is an advantage that the usage and range of use of one brush can be widened.

  The best embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a brush according to the present embodiment, FIG. 2 is a front view and a bottom view of a brush member of the brush, and FIG. 3 is a cross-sectional model view showing each stage of a flocking process.

The brush 1 shown in FIG. 1 is attached to the tip of the heel handle, and is formed by inserting a brush member bundle 4 into a flock hole 3 drilled in a base 2 and fixing it.
The pedestal 2 is made of synthetic resin or the like, and an attachment portion 6 for attaching a handle (not shown) of a cleaning tool is provided on the upper surface of the pedestal 2.
Further, two rows of flock holes 3 are formed in the lower surface of the base 2 along the longitudinal direction. The inner diameters of the flocking holes 3 are formed to be equal, and a plurality of brush members 5 a and 5 b having different hardnesses are implanted in the flocking holes 3.

FIG. 2A is a front view of the brush member bundle 4, and FIG. 2B is a bottom view of the brush member bundle 4. As shown in FIGS. 2 (a) and 2 (b), the soft brush member 5b is planted so as to be positioned at the center of the tuft hole 3, and the hard brush member 5a is planted so as to be positioned on the outer periphery of the soft brush member 5b.
Further, as shown in FIG. 2A, the hard brush member 5a is formed shorter than the soft brush member 5b.

As the hard brush member 5a, a synthetic fiber such as polypropylene having a diameter of about 0.4 to 1.0 mm is preferably used.
As the soft brush member 5b, synthetic fibers such as nylon, polyethylene, polyvinyl alcohol and the like having a diameter smaller than that of a hard brush member and having a diameter of about 0.05 mm to 0.05 mm, animal fibers such as pig hair and horse hair, palm, fern, etc. Plant fibers can be used alone or in combination.
In short, the hardness of the brush member is relative and is not limited to the above example, and various wire materials can be used in combination.

  As shown in FIG. 3 (a), the method for flocking the brush member bundle 4 into the flocking hole 3 includes a bundle of hard brush members 5a and a soft brush member 5b among two types of brush members 5a and 5b having different hardnesses. When the bundles are separated and stacked, grasped by the gripping tool 7, and folded in half so that the soft brush member 5a is on the inside, the hard brush member 5a is softly bent as shown in FIG. 3B. Arranged outside the member 5b.

The folded portion 8 of the brush member bundle 4 consisting of the bundle of brush members 5a and 5b folded in half is inserted into the flocking hole 3, and the fixing needle 9 is inserted into the folded portion 8 as shown in FIG. The brush member bundle 4 is fixed in the flock hole 3 by the fixing needle 9.
Thereby, the brush member bundle 4 becomes an open radial bundle and protrudes from the surface of the pedestal 2 where the implantation hole 3 is formed.

The brush 1 manufactured in this way can clean fine dust, dust, dust, and the like with the soft brush member 5b, and can clean relatively large and bulky dust with the hard brush member 5a.
Further, since the hard brush member 5a is positioned on the outer periphery of the soft brush member 5b, the soft brush member 5b is reinforced and firm, and the brush member bundle 4 can be maintained upright from the flocked hole 3.
Therefore, when the brush 1 is used, the soft brush member 5b does not bend from the base and interfere with the cleaning operation.

  Further, since the hard brush member 5a is formed shorter than the soft brush member 5b, the hard brush member 5a is deformed flexibly along the shape of the surface to be cleaned of the soft brush member 5b when collecting fine dust, dust, and the like. There is no hindrance.

In the above embodiment, the brush 1 used for the scissors is taken as an example. However, the brush of the present invention is not limited thereto, and may be used for other cleaning tools such as a brush portion such as a deck brush. it can.
When the brush according to the present invention is used for a deck brush, it is possible to use a cracked fiber formed by dividing the tip of a soft brush member, and the cracked fiber is usually very soft and not stiff. However, there is an advantage that the brush member bundle can be reinforced by disposing a hard brush member on the outer periphery of the cracked fiber.
In addition, even when a hard brush member is disposed on the outer periphery of a soft brush member, it is possible to maintain good water retention of the cracked fiber as it is. A brush having a high strength can be provided.

It is a perspective view of the brush concerning one embodiment of the present invention. It is the front view and bottom view of the brush member bundle of the brush. It is a figure which shows the manufacturing method of the said brush.
