Abstract

PROBLEM TO BE SOLVED: To provide a car washing machine rotary brush for washing a car efficiently by improving durability of a washing part. SOLUTION: In a car washing machine rotary brush constructed of a washing body 2, which is folded into an approximately corrugated shape so as to be provided with a cross section possessing crest parts 3 and valley parts 4, one end is formed into a mounting part A to be installed in a rotary shaft, while the other end is formed into washing parts B, which are spread in the circumference direction and is brought into contact with the surface of a vehicle body during washing. In the crest parts 3 and the valley parts 4 in the washing parts B, slits 6 with the predetermined length are formed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary brush for a car washer which is incorporated in a car washer and is used for cleaning the upper and side surfaces of a vehicle body.

[0002]

2. Description of the Related Art As a rotary brush for a car washer, a configuration using a brush bristle made of cloth or the like instead of a brush bristle made of resin has been considered. As this kind of rotary brush for a car washer, for example, a body washing body unit disclosed in Japanese Patent Application Laid-Open No. 6-107133 has been proposed. This conventional configuration,
The cross-sectional shape is bent as a corrugated shape having peaks and valleys, and one end is formed on the mounting portion by making the slopes between the peaks and valleys adhere to each other, and the other end is formed on the mounting portion. A plurality of cuts are made in the inclined portion toward the cleaning portion to form a fan-shaped unit as a whole.

[0003]

By the way, in the case described above, a cut is made in a slope portion of a washing portion and each one is thin, so that the washing portion is peeled off by friction with a vehicle body at the time of car washing, so that the washing portion is quickly removed. It can be exhausted.
There is also a disadvantage that the cleaning efficiency varies depending on the depth of the cut.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a rotating brush for a car washer capable of improving the durability of a washing portion and performing efficient car washing. That is.

[0005]

According to the present invention, in order to solve such a problem, a cross-sectional shape is bent into a substantially corrugated shape having peaks and valleys, and one end is attached to a rotating shaft. In the rotating brush for a car washing machine, the other end is formed in a washing portion which is brought into contact with the surface of the vehicle body at the time of car washing, and is constituted by a washing body connected in a circumferential direction.
Since a predetermined length of cut is made in the peaks and valleys of the cleaning portion, the cleaning portion is formed wide, so that a certain degree of rigidity is obtained and durability is improved.

[0006] Further, since the length of the cleaning body is 400 mm and the notch is formed with a length of 150 mm to 200 mm, the cleaning efficiency is improved by following dirt on the uneven portion of the vehicle body.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a plurality of cleaning bodies 2 are mounted in a horizontal direction and a vertical direction on a rotating shaft 1 rotated on a top surface, both side surfaces, and the like of a vehicle body by a motor similar to a conventional car wash brush. . As shown in FIG. 2, the cleaning body 2 is formed of a flexible cloth having a length of 400 mm, and is folded into a substantially corrugated shape having a peak portion 3 and a valley portion 4 at one end thereof. It is formed on a mounting portion A having a hole 5 for mounting on the rotating shaft 1, and the other end is formed on a cleaning portion B which comes into contact with the surface of the vehicle body when the vehicle is washed. In the cleaning body 2, cuts 6 having a length of 150 mm to 200 mm are formed in the peaks 3 and the valleys 4 from the cleaning part B toward the mounting part A, and each of the notches 6 spreads one by one by centrifugal force during car washing. It comes into contact with the surface.

As shown in FIG. 3, a screw 7 is inserted into a hole 5 formed in the mounting portion A and attached to the rotating shaft 1 by using a plurality of the cleaning bodies 2, and the cleaning bodies 2 are attached to each other. A plurality of disk-shaped units 8 are sewn together and attached in the axial direction of the rotating shaft 1.

In the above arrangement, the unit 8 is rotated and rotates to contact the vehicle body to clean the vehicle body. At this time, the cleaning portion B is divided into individual pieces, radially spread by centrifugal force, and comes into contact with the vehicle body surface and the concave portion at the width of the peak portion 3 and the valley portion 4, so that the durability is improved by a certain degree of rigidity. Is improved, and uniform car washing is performed.

[0010]

The rotary brush for a car washer according to the present invention is as described in detail above, and the washing portion is cut into the width between the peaks and the valleys, so that a certain degree of rigidity is obtained. And the durability is improved. The length of the washing body is 4
Since the cut is formed with a length of 150 mm to 200 mm, if there is no cut, the tip will be deformed. If the cut is too short, the contact pressure with the car body will be insufficient and dirt will not be removed, and the cut If the length is too long, the inconvenience that the brush cannot follow the concave portion of the vehicle body and the unwashed portion is generated is eliminated, and the uniform cleaning effect can be obtained by following the concave and convex portion of the vehicle body.
