Description

[Detailed Description of the Invention] The present invention relates to a cleaning brush used for cleaning the surface of a vehicle body.

Generally, when washing a car, water is sprayed onto the surface of the car body using a hose or the like, and mud and dust are wiped away using a car wash brush.

When wiping off mud and dust with such a car wash brush,
Mud and dust cannot be reliably removed unless the bristles of the car wash brush are moved while being pressed against the surface of the car body with a predetermined pressure, so the wiping operation requires a considerable amount of effort.

Particularly, when cleaning the roof of a car body, this labor increases even further.

The present invention was developed in view of this point, and its purpose is to be able to wipe away dirt from surfaces to be cleaned, such as the surface of a car body, with little effort, and to be able to reliably clean even curved surfaces of surfaces to be cleaned. An object of the present invention is to provide an improved cleaning brush.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an example of a cleaning section constituting a cleaning brush according to the present invention, in which FIG. 1 is a partially cutaway front view, FIG. 2 is a partially cutaway side view, and FIG. 3 is a bottom part. It is.

In each country, 1 is a brush support body, and a substantially semicylindrical recess 1a is formed inside this brush support body 1.

A large number of brush bristles 2 are implanted on the end surface 1b of the brush support 1, which forms the outer edge on the opening side of the recess 1a. A magnet roller 4 made of a rubber magnet is attached.

The magnetic roller 4 is rotatably supported in the recess 1a of the brush support 1 so that it rolls on the surface to be cleaned by the brush bristles 2 when the brush support 1 is moved during cleaning. ing.

The cleaning brush according to the present invention is constructed using a plurality of cleaning parts 10 having each part formed in this manner.

FIG. 4 shows one example, in which four cleaning sections 10 are provided.

These cleaning units 10 are connected by connecting members 11 and 12 so that they can be arranged in a cross shape.

Each of the connecting members 11 and 12 is made of flexible plastic or the like.

Note that 11' and 12' are plate parts for connecting the connecting members 11 and 12 and the cleaning section 10, respectively;
is a handle attached to the connecting member 12.

When the cleaning brush according to the present invention configured as described above is used for cleaning a metal surface to be cleaned such as a car body surface, for example,
When cleaning a portion having a concave curved surface, the brush bristles 2 side are pressed against the concave curved surface P as shown in FIG. Due to its nature, it is pressed along the concave curved surface P.

Accordingly, the circumferential surface of the magnetic roller 4 provided in each cleaning section 10 is attracted to the concave curved surface P.

Thereafter, the entire cleaning brush is moved along the concave curved surface P using the handle portion 13, so that the respective cleaning portions 10
The brush bristles 2 planted on the brush support 1 wipe off dirt such as mud and dust adhering to the concave curved surface P.

At this time, the periphery of the magnetic roller 4 attached to each of the cleaning sections 10 is constantly attracted to the concave curved surface P while rolling on the concave curved surface P, so that the entire cleaning brush is lightly pressed against the concave curved surface P. Dirt can be wiped away with just a single touch, and only a small amount of force is required to move the cleaning brush.

Therefore, the labor required for wiping work is significantly reduced.

The magnetic roller 4 moves while adhering to the concave curved surface P, but since the magnetic roller 4 is made of a rubber magnet and rolls, there is no risk of scratching the concave curved surface P. .

In addition, when a part having a convex curved surface is cleaned, the sixth
As shown in the figure, due to the flexibility of the connecting members 11 and 12,
Magnet rollers 4 attached to each cleaning section 10 are attracted to the convex curved surface Q, and the brush bristles 2 are pressed along the convex curved surface Q.

Thereafter, by moving the entire cleaning brush along the convex curved surface Q, dirt adhering to the convex curved surface Q is wiped off in the same manner as in the case of cleaning the concave curved surface P.

In the example shown in FIG. 6 described above, when the radius of curvature of the convex curved surface Q becomes small, there is a possibility that the lower portions of the brush supports 1 of the plurality of cleaning sections 10 collide with each other.

FIG. 7 shows an example in which such collision is prevented.

In FIG. 7, a large number of brush bristles 21 similar to those described above are implanted on the end surface 20b of each of the brush supports 20 of the four cleaning sections 30, and a magnet roller 22 is rotatably provided in the recess 20a. attached.

Grooves a-j and protrusions A-J are formed in mutually opposing portions of the brush supports 20 of these four cleaning units 30.

The four cleaning sections 30 are connected by flexible connecting members 23 and 24 so as to be arranged in a cross shape.

The groove a corresponds to the protrusion A, and the width of the groove a is larger than the width of the protrusion A.

The respective correspondences between the other grooves b-j and the other protrusions B-J and the magnitude relationship between the widths of the grooves b-j and the widths of the protrusions B-J are based on the above-mentioned grooves a and protrusions A. The relationship is similar to that of

Therefore, when the cleaning brush of this example, which is composed of the four cleaning parts 30 connected by the connecting members 23 and 24, is used for cleaning a surface to be cleaned having a convex curved surface, the cleaning brush on the left and right sides is cleaned along the convex curved surface. The portions 30 are inclined inward to approach the central cleaning portion 30, but the convex portions A-J engage with the insides of the grooves a-j, so that the cleaning portions facing each other are moved inwards. This prevents the brush supports 20 of the portion 30 from colliding with each other.

Furthermore, it goes without saying that not only curved surfaces but also flat surfaces can be cleaned reliably with little effort by the attraction and rolling action of the magnetic rollers 4 or 22.

As is clear from the description of the above-mentioned embodiments, the cleaning brush according to the present invention allows reliable cleaning by simply pressing the brush lightly against the surface to be cleaned and moving it with very little force; Even if the surface to be cleaned has a convex or concave curved surface, sufficient cleaning can be performed without any inconvenience, and there is an advantage that the labor required for cleaning work can be significantly reduced.

This advantage is particularly significant when cleaning surfaces with many curves, such as the surface of a car body.

In the above-described embodiment, a handle portion 13 is provided, but instead of the handle portion 13, one end of a rod-shaped member is attached to the connecting member, and the other end of this rod-shaped member is held by hand. It's okay.

Further, the nozzle for water sprinkling may be housed in the cleaning section or fixed in the vicinity of the cleaning section. It is also possible to supply water.

Furthermore, regarding other components, the present invention is not limited to the scope of the above-mentioned embodiments, and may be modified without departing from the gist, such as making the magnetic roller not cylindrical but spherical or polygonal. Of course, various modifications may be made.
