JPH01185202A - Polisher and manufacture of brush thereof - Google Patents

Abstract

PURPOSE:To make it possible to surely perform cleaning without disfiguring a surface to be cleaned on any different condition of the cleaning by arranging the outer ends of respective brush hairs in a cylindrical shape and making the brush hairs in the center of the tip of a brush base shorter and thinner than the other. CONSTITUTION:A brush body 7 is formed by planting brush hairs 9 on a semi- spherical brush base 8 while arranging the outer ends thereof in a cylindrical shape. The brush hairs 9a in the center of the front part of the brush base 8 is made to be shorter and thinner than the other. With this arrangement, when the cleaning is performed in the front surface of the brush body 7, the operational force is transmitted to the surface to be cleaned mainly through the center of the front surface of the brush hairs 9. Since the brush hairs 9a is made to be shorter and thinner, it is possible to surely perform the cleaning without disfiguring the surface to be cleaned.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a polisher used for cleaning baths, for example, and a method for manufacturing its brush body.

BACKGROUND OF THE INVENTION Conventionally, this type of polisher has a main body with a built-in motor and a brush body, which is rotated by the motor. The brush body had synthetic resin bristles planted on the brush stand.

Problems to be Solved by the Invention However, with the above-mentioned conventional methods, for example, when cleaning a bathtub, a brush body with soft and small-diameter bristles is required to prevent damage. It was unsuitable for cleaning heavily soiled tiles.

On the other hand, if the brush bristles have a large diameter, they may damage bathtubs and the like when cleaning them.

The present invention has solved these problems, and an object of the present invention is to provide a polisher that can clean the surface reliably and without causing scratches even if the conditions of the surface to be cleaned are different.

Means for Solving the Problem A first means of the present invention for achieving the above-mentioned object is a main body having a built-in motor etc., and a brush body provided substantially linearly in front of the main body and rotationally driven by the motor. This brush body is formed by planting brush bristles on a substantially semicircular brush stand, and the outer ends of each brush bristles are arranged in a cylindrical shape, and the medium heat part at the tip of the bluff stand is arranged in a cylindrical shape. The bristles are shorter than others and have a small diameter.
The brush body is made by cutting the root side of two types of long and short animal brush bristles to a certain length, bending them in half, and planting the bent parts on a roughly semicircular brush stand. Concentrate the shorter bristles on the medium heat part of the tip of the brush stand,
Then, cut the tips of each brush bristles into a cylindrical shape.
Manufactured by grooming.

Another means is a main body with a built-in motor, and a brush body provided in front of the main body and rotated by the motor. The brush body is constructed by implanting brush bristles with a mixture of small-diameter long bristles.The brush body is made by bending the animal brush bristles in the middle so that the root side becomes short, and planting the bent part on the brush stand. Manufactured as specified.

Effect In the first means described above, the direction in which the operating force is directly transmitted when operating the polisher is the front, which is in a linear relationship with the main body. At this time, the cleaning function is performed in the front part of the brush body, where short but small-diameter brush bristles are installed, so that the surface to be cleaned is not damaged and can be cleaned reliably. The outer circumferential portion of the brush body (67, -7) has large-diameter bristles, so if you apply this portion to heavily soiled areas such as tiles, you can perform powerful cleaning.

This brush body can be easily made by bending and planting two types of animal brush bristles, long and short, on a brush stand.

With the second means, the long or short bristles of the brush bristles can be applied to the surface to be cleaned by changing the strength of the operating force. for example,
In the case of bathtubs, which tend to get damaged easily, by lowering the operating force, the flexible long hairs will hit, while in the case of tiles, by increasing the operating force, the long hairs will sag and the strong short hairs will hit.

This brush body can be easily made by bending animal brush hair so that the root side becomes shorter and planting it on a brush stand.

Example The embodiment will now be described with reference to the accompanying drawings.

In FIG. 1, a handle 1 is formed at the rear, and a substantially cylindrical main body 2 has a motor 4 with a reduction gear 3 and a battery 5 serving as its power source installed therein, and e, -> reduction gear 3 The output shaft 6 projects forward of the main body 2, and a brush body 7 is attached thereto. The brush body 7 has brush bristles 9 arranged radially in a semicircular brush stand 8 so as to have a cylindrical outer periphery. Of the brush bristles 9, the front center portion 9a of the brush stand 8 is shorter than the other portions 9b, and is set to have a smaller diameter.

In the above configuration, when cleaning is performed on the front surface of the brush body 7, the operating force is mainly applied to the front central portion 9a of the brush bristles 9.
is transmitted to the surface to be cleaned via. The front medium heat portion 9a has short bristles but a small diameter, so it can be cleaned reliably without damaging the surface to be cleaned, and is suitable for use in bathtubs. The other part 9b has long bristles, but has a large diameter and is strong, so if you apply the part 9b to the surface to be cleaned, powerful cleaning is possible.For example, it can be used for cleaning heavily soiled tiles. It is suitable as

FIGS. 2 to 6 show a method of manufacturing the brush body 7, in which two types of tapered animal brush bristles 9'19'', long and short, are made to have a constant length of 7 hairs on the root side.

That is, cut off at A-A', then bend over medium heat.

Then, the short animal brush bristles 9'' are located at the center of the front surface of the brush body 8, and the long animal brush bristles 9' are located at the outer periphery of the brush body 8, and their respective bent portions are implanted via the fasteners 10. Finally, when the external shape becomes cylindrical, <B-C-D
-E to obtain the brush body 7 shown in FIG. It goes without saying that the short animal bristle 9'' has a smaller diameter at its root side than the ipsilateral diameter of the long animal bristle 9'.

Next, in FIG. 6, instead of the brush bristles 9 in FIG. 5, the brush stand 8 has short bristles 11 with a large diameter and long bristles 12 with a small diameter coexisting therein. Therefore, when cleaning a surface that is easily scratched, such as a bathtub, the operating force should be weakened so that only the long bristles 12 come into contact with it, and when cleaning a heavily soiled surface such as tiles, the operating force should be increased. As a result, the long hair 12 is displaced and the stiff short hair 11 also comes into contact with it.

This brush body 7 has animal brush bristles 1 as shown in FIG.
3 so that the base side becomes shorter, and the bent portion is installed on the brush stand 8 via the stopper 10.

Effects of the Invention As described above, according to the present invention, the properties of the brush bristles that hit the surface to be cleaned differ depending on the operating direction or operating force, and dirt can be removed reliably and firmly without causing any damage. It is very easy to use and can be used efficiently.

Further, the brush body has excellent effects such as being easily manufactured by adjusting the method of bending the animal brush bristles and adjusting the implantation site.
