Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a car wash brush used for an automatic car wash machine. More specifically, the present invention relates to a car wash brush using a woven fabric, a non-woven fabric or a knitted fabric instead of a bristle material, and an automatic car wash machine provided with the car wash brush.

[0002]

[Prior art]

 Conventionally, it has been proposed to use a woven fabric or a nonwoven fabric instead of a bristle material in a car wash brush of an automatic car wash machine since a soft texture is easily obtained (Japanese Patent Application Laid-Open No. 5-229410).

[0003] The conventional car wash brush using a woven or non-woven fabric is obtained by folding a woven or non-woven fabric of a predetermined length into a narrow width by alternately repeating mountain folds and valley folds, and then, at a central portion in the length direction. One unit is folded in two, and the inner side edges are sewn together to form a fan shape. One unit is formed, and a plurality of units are arranged in a circle with the base side of the two folds (the required side of the fan) inside. The unit is sewn together on both side edges and attached in multiple stages to the brush shaft. In other words, the shirred circular woven or nonwoven fabric is attached in multiple stages to the brush shaft.

[0004]

[Problems to be solved by the invention]

 However, in the case of the above-mentioned conventional car wash brush, since the woven fabric or nonwoven fabric that is rotated and wipes the car body is divided into upper and lower stages, there is a problem that a streak-like unwashed portion is easily generated between the upper and lower woven fabric or nonwoven fabric. is there. In addition, a woven or non-woven fabric having a predetermined length must be sewn in several places, and there is a problem that the production is troublesome.

[0005] The present invention has been made in view of the above-mentioned problem, and has been developed for a car wash brush using a woven cloth, a non-woven cloth, or a knitted cloth instead of a bristle material without leaving any washing, and is easy to manufacture. It is intended to be a car wash brush.

[0006]

[Means for Solving the Problems]

 For this reason, in the present invention, cuts are made at a fixed interval on one side, and the long cloth which is bundled and cut into a gap between the cuts is spirally wound around the brush shaft, and the bundle is brushed. The bundle is fixed to the brush shaft at fixed intervals around the shaft, and the fixing position of the bundled portion to the brush shaft is 3 or more in length in a spiral around the brush shaft along the winding state of the fabric. This is a car wash brush characterized in that it is set at a position where it is equally divided by an odd number.

[0007] The present invention also provides an automatic car washer provided with the car wash brush as at least one of a top brush, a side brush, and a rocker brush.

[0008]

[Embodiment of the invention]

 FIG. 1 is a plan view of a long fabric 1 used for the car wash brush of the present invention in an unfolded state. The cloth 1 is attached in such a manner that the cloth 1 is spirally wound around a brush shaft 2 (see FIG. 3), which will be described later, instead of the bristle material. It is configured. The width of the cloth 1 varies depending on the size of the car wash brush, but is usually 30 to 45 cm. The fibers constituting the fabric 1 may be natural fibers or synthetic fibers, but synthetic fibers are preferable in terms of strength.

The cloth 1 is preferably waterproofed so that it absorbs water during car washing, becomes excessively heavy, and does not give a strong impact to the vehicle body or increase the load on the device. The waterproof process may be a general water-repellent process, but from the viewpoint of obtaining good waterproof performance over a long period, a waterproof process by resin direct coating is preferable. This resin direct coating is a method in which a resin and a necessary additive are dissolved in a solvent, and a coating material adjusted to an appropriate viscosity is applied to the cloth 1 and dried, and a resin coating is formed between the fibers constituting the cloth 1 and on the cloth. Is waterproofing.

The fabric 1 has cuts 3 formed at one side thereof at regular intervals. Further, it is preferable that the tip of the cut 3 is a stop hole 4 punched in a circular shape in order to prevent the cloth 1 from being torn from this portion.

As shown in FIG. 2, the space between the cuts 3 in the fabric 1 is gathered and bundled to form a bundle 5.

The attachment of the fabric 1 to the brush shaft 2 will be described. As shown in FIG. 3, the fabric 1 is wound spirally around the brush shaft 2 with the bundled portion 5 side facing the brush shaft 2 side. It is attached by fixing the bundle 5 to the brush shaft 2 with screws 6. The fabric 1 attached to the brush shaft 2 overlaps multiple times and is gathered at the bundling portion 5 so that the fabric 1 does not hang down along the brush shaft 2, and extends greatly around the brush shaft 2. It is attached. Therefore, at the time of car washing, it is possible to make the tip of the cloth 1 (the side opposite to the side where the cut 3 is formed) easily come into contact with the vehicle body.

As shown in FIG. 4, the bundle 5 may be attached to the brush shaft 2 with the bundle 5 oriented in a direction perpendicular to the center axis of the brush shaft 2. As shown in the figure, it is preferable that the bundling portion 5 is directed downward in the direction of the center axis of the brush shaft 2. By doing so, the fabric 1 attached around the brush shaft 2 is unlikely to hang down, and easily protrudes around the brush shaft 2.

If the cuts 3 provided in the cloth 1 are too deep, the tension of the cloth 1 when attached to the brush shaft 2 becomes weak, and if the depth is too small, it becomes difficult to bundle the cuts 3. Also, if the interval between the cuts 3 is too wide, it is difficult to bind the cuts 3 unless the depth of the cuts 3 is too large, and if it is too narrow, the amount of folds when the bundles 3 are bundled is small. Tension of 1 becomes weak. Therefore, it is preferable that the depth and the interval of the cuts 3 are 10 to 20 cm and the interval is 80 to 120 m.

The position at which the bundle 5 is fixed to the brush shaft 2 (the position of the screw 6) is such that the length between two turns around the brush shaft 2 spirally along the winding state of the fabric 1 is 3 or more. It is set at the position where the odd number is divided equally. In particular, since the brush shaft 2 is a circular tube having an outer diameter (diameter) of about 70 to 140 cm (currently used one having an outer diameter of 89 to 114 cm), the brush shaft 2 spirals along the winding state of the cloth 1. It is preferable that the length between two rounds of the brush shaft 2 be set at a position that divides it into seven equal parts, since the most stable mounting state can be easily obtained.

FIG. 6 is a plan view showing a state where the brush shaft 2 is cut open in the direction of the center axis thereof. The case where the brush shaft 2 is divided into seven parts will be further described with reference to FIG.

In the drawing, a to h show eight fixed positions of the binding portion 5 to the brush shaft 2, which are set at equal intervals. The fixed position h is located at substantially the same position as the fixed position a in the direction of the center axis of the brush shaft 2, and the cloth 1 spirals around the brush shaft 2 from the fixed position a to the fixed position h. It surrounds two times in a circle. In other words, the fixed positions a to h are set at positions that divide the length between two turns around the brush shaft 2 spirally along the wound state of the fabric 1 into seven equal parts.

As is apparent from FIG. 6, when the fixed positions a to h are set at the above positions, the fixed positions a to d in the first round and the fixed positions e to h in the second round are It will be staggered in the direction of the central axis of shaft 2. The fabric 1 attached around the brush shaft 2 has tension at the fixed positions a to d, but the portion between them tends to hang down. With such fixed positions a to h, the positions of the fixed positions a to d and e to h in the first and second laps are shifted by ピ ッ チ pitch, and the portion where the first lap is likely to sag is two laps. Since it is supported at the fixed positions e to h where the eyes are not easily drooped, it is easy to keep the entire body tight.

Although FIG. 6 shows the second round, this is repeated from the third round. FIG. 6 shows a case where the fixed positions a to h are set at positions that divide the length between two turns around the brush shaft 2 in a spiral along the wound state of the fabric 1 into seven equal parts. However, if the fixed positions a to h are three or more odd-numbered positions, the first and second laps are shifted from each other in a zigzag manner as described above.

FIG. 7 shows another example of the present car wash brush, which is basically the same as that described with reference to FIGS. 1 to 6, except that the fabric 1 has a large number of mountain folds and valleys in the longitudinal direction. They differ in that they are pleated, which alternately repeats folding. That is, the car wash brush of FIG. 7 is in a state in which a long pleated skirt is spirally wound around the brush shaft 2. Although such pleating has a disadvantage in that it is costly, it can be employed when it is desired to make the contact with the vehicle body softer.

The present car wash brush can be used as a top brush 8, a side brush 9 or a rocker brush 10 of an automatic car wash machine 7 as shown in FIG. The top brush 8 is installed substantially horizontally on the upper part of the automatic car washer 7 and is rotated to wipe the upper surface of the vehicle body. The side brush 9 is installed substantially vertically on both sides of the automatic car washer and is rotated. , For wiping the front and rear surfaces and both side surfaces of the vehicle body. The rocker brush 10 is installed almost vertically at the lower part on both sides of the automatic car washer and is a small-sized one that is rotated and is used for wiping a tire and a dirty lower part of the vehicle body. The present car wash brush has a great feature in that a good overhang of the fabric 1 can be maintained even when the rotation of the brush is stopped, and even if the brush 1 is used as any brush in the automatic car washing machine 7, the fabric 1 droops. It is possible to prevent the deviation or deviation. Therefore, when the automatic car washer 7 uses the main car wash brush as at least one of the top brush 8, the side brush 9, and the rocker brush 10, the performance of the automatic car wash machine 7 can be greatly improved. It is needless to say that the top brush 8, the side brush 9, and the rocker brush 10 are all ideally the car wash brushes of the present invention.

[Effect of the invention]

 The present invention is as described above, and has the following effects.

(1) In the car wash brush of the present invention, since the fabric 1 is attached in a spiral shape, the tip of the attached fabric 1 is not separated in multiple stages in a row, so that the contact area of the car wash brush is large. It can be wiped evenly and does not leave any residue.

(2) Basically, it can be manufactured by winding and fixing a series of long fabrics 1 while partially bundling them, and can be manufactured without sewing. Therefore, manufacturing is easy.

(3) In particular, the fixing position of the bundle portion 5 to the brush shaft 2 is an odd number of 3 or more, which is a length between two turns around the brush shaft 2 spirally along the winding state of the fabric 1. By setting the position to be equally divided, the cloth 1 can be attached in a state of protruding greatly around the brush shaft 2, and a car wash brush which can be easily brought into contact with the vehicle body can be obtained.

(4) The automatic car washer provided with the main car wash brush as at least one of the top brush 8, the side brush 9 and the rocker brush 10 makes contact with the body of the fabric 1 in the car wash area of the brush. However, it is possible to obtain a good cleaning effect without damaging the vehicle body with reliability and softness.
