Hereinafter, the present invention will be specifically described with reference to the drawings.

(1) Configuration of Cleaning Brush The cleaning brush 1 according to the present embodiment cleans the tire 21 and the wheel 22 (see FIGS. 5 and 6). As shown in FIGS. 1 to 3, the cleaning brush 1 is divided into a disk-shaped base plate 2 and the surface of the base plate 2 in the circumferential direction (specifically, the cleaning brush 1 is divided in the circumferential direction at equal angular intervals). A brush structure 3 described later, which is arranged in each of a plurality of (five in the drawing) regions a1 to a5, is provided.

The base plate 2 is an injection-molded product made of a synthetic resin (for example, PCV or the like). The thickness t1 of the base plate 2 is about 15 mm (see FIG. 4). Further, a rotatable horizontal shaft 23 is connected to the central portion of the back surface of the base plate 2 (see FIG. 6).

(2) Structure of brush structure As shown in FIGS. 1 to 3, the brush structure 3 according to the present embodiment is detachably attached to each region a1 to a5 on the surface of the base plate 2 and is attached in the thickness direction. It is provided with a split sheet 5 in which a large number of flocking holes 4 are formed so as to be inclined and penetrated, and a hair material 6 in which hair is transplanted on the surface of the split sheet 5 through the flocking holes 4.

The split sheet 5 is an injection-molded product formed of an elastic material (for example, a synthetic resin elastomer or the like). The divided sheet 5 is formed in a fan shape (specifically, an annular fan shape) in a plan view (see FIG. 7). Further, the thickness t2 of the divided sheet 5 is set to about 3 mm (see FIG. 4).

As shown in FIGS. 4 and 7, a plurality of (five in the figure) pedestals 9 for receiving the heads such as screws 8 and rivets are projected on the surface of the divided sheet 5. Each of these pedestals 9 is formed with an insertion hole 9a through which a shaft portion such as a screw 8 or a rivet is passed. Then, the split sheet 5 is detachably attached to the base plate 2 by screwing the screw 8 or driving a rivet into the pedestal 9 with the split sheet 5 arranged on the base plate 2. The pedestal 9 also protrudes from the back surface side of the split sheet 5 and functions as a protrusion 12 described later (see FIG. 10).

As shown in FIGS. 4 and 11, a fall prevention wall 10 for preventing the hair material 6 from falling outward is erected on the outer edge of the surface of the split sheet 5 (see FIGS. 7 to 9). .. The fall prevention wall 10 is formed in the shape of an arc plate extending in the circumferential direction of the base plate 2. Further, on the surface of the split sheet 5, a holding cylinder 11 for holding the root portion of the hair material 6 is set up at a position surrounding each flocking hole 4. Further, on the back surface of the divided sheet 5, a plurality of protrusions 12 that come into contact with the front surface of the base plate 2 are provided (see FIG. 10). A plurality of the protrusions 12 are arranged along the outer peripheral edge of the back surface of the divided plate 5, and a plurality of the protrusions 12 are also arranged inside the outer peripheral edge thereof.

As shown in FIG. 4, the axis of the flocking hole 4 is inclined at a predetermined inclination angle θ (for example, about 7 degrees) with respect to the thickness direction of the split sheet 5. Then, the hair material 6 planted through the hair transplanting holes 4 is in an inclined posture in the centrifugal direction of the base plate 2. Specifically, the axial center of the flocking hole 4 is such that when the split sheet 5 is arranged in the front surface regions a1 to a5 of the base plate 2, the front side opening 4a of the split sheet 5 is larger than the back surface side opening 4b. It is tilted so as to be displaced toward the distal side of the base plate 2. The opening 4a on the front surface side and the opening 4b on the back surface side have substantially the same area and are located so as to partially overlap each other in the plan view of the divided sheet 5.

Here, the mold for injection molding the split sheet 5 (not shown) includes a pair of molds that are close to each other in the axial direction of the flocking hole 4. These pair of molds include molding surfaces that form the front and back surfaces of the split sheet 5. These molding surfaces are inclined with respect to a plane orthogonal to the axis of the flocking hole 4 (that is, the mold clamping direction of the pair of molds).

The hair material 6 is a bundle of finely foamed or non-foamed synthetic resin wire rods. The hair material 6 is folded in half in the length direction and inserted into the holding cylinder 11 with the central folded portion as a base. By introducing the thread 14 through the back surface of the split sheet 5 into the flocking hole 4 so as to straddle the folded portion of the hair material 4, the root portion of the hair material 6 is held in the holding cylinder 11.

As shown in FIGS. 11 and 12, the hair material 6 includes a tire hair material 6a for cleaning the tire 21 and a wheel hair material 6b for cleaning the wheel 22. The tire bristle material 6a is held in the holding cylinder 11 located in the outer region b1 of the split sheet 5, and the wheel bristle material 6b is held in the holding cylinder 11 located in the inner region b2 of the split seat 5. It is retained (see FIG. 7). Further, the hair material 6a for tires is formed of a material harder than the hair material 6b for wheels. Further, the length L of the hair material 6a for the tire is set to a value larger than the lengths L1 and L2 of the hair material 6b for the wheel. Further, the color of the tire hair material 6a (for example, black) and the color of the wheel hair material 6b (for example, blue) are different. As a result, the design is enhanced.
The length L of the hair material 6a for the tire may be set to a value smaller than the lengths L1 and L2 of the hair material 6b for the wheel, and the lengths L1 and L2 of the hair material 6b for the wheel are abbreviated. It may be set to the same value.

As shown in FIG. 7, the wheel bristle material 6b is the circumference of the first wheel bristle material 16a arranged in the first region c1 and the first region c1 and the base plate 2 on the surface of the divided sheet 5. It includes a hair material 16b for a second wheel arranged in a second region c2 adjacent to each other in the direction. Specifically, the hair material 16a for the first wheel is held in a plurality of holding cylinders 11 arranged in the first region c1, and the hair material 16b for the second wheel is arranged in the second region c2. It is held in a plurality of holding cylinders 11. The length L1 (for example, 300 mm) of the hair member 16a for the first wheel is set to a value larger than the length L2 (for example, 250 mm) of the hair member 16b for the second wheel (see FIG. 11).

(3) Action of cleaning brush Next, the action of the cleaning brush having the above configuration will be described. As shown in FIG. 6, the cleaning brush 1 is rotated by the rotation of the horizontal shaft 23 and pressed against the tire 21 and the wheel 22, so that the cleaning brush 1 cleans the tire 21 and the wheel 22. At this time, the outside of the wheel 22 is cleaned by the hair material 16a for the first wheel, and the inside of the wheel 22 is cleaned by the hair material 16b for the second wheel, which is shorter than the hair material 16a for the first wheel.

(4) Effect of Example According to the brush structure 3 and the cleaning brush 1 of this example, the disk-shaped base plate 2 is detachably attached to each of a plurality of regions a1 to a5 divided in the circumferential direction. In addition, the split sheet 5 is provided with the flocking holes 4 inclined in the thickness direction, and the flocking material 6 is flocked on the surface of the flocking sheet 5 through the flocking holes 4. As a result, when the split sheet 5 is injection-molded, the inclined flocking holes 4 can be formed at the same time, and the processing and manufacturing time can be shortened. Further, by changing the number of brush configurations 3 used, it is possible to correspond to the base plates 2 of various sizes. Further, when the hair material 6 is damaged or the like, only the brush structure 3 is replaced, so that the base plate 2 can be reused and waste can be reduced. Further, the size, number, and the like of the flocking holes 4 can be freely set while maintaining the strength of the base plate 2.

Here, the tire of the vehicle has various sizes such as 13 to 20 inches, and the size of the base plate 2 is also changed accordingly. Specifically, when the base plate 2 having a diameter of 400 mm is adopted, five brush components 3 are used in order to secure an appropriate cleaning area (see FIG. 13A). On the other hand, when the base plate 2 having a diameter of 450 mm is adopted, six brush configurations 3 are used in order to secure an appropriate cleaning area (see FIG. 13 (b)).

Further, in this embodiment, the divided sheet 5 is made of an elastic material. As a result, since the hair material 6 is planted in the flexible hair transplantation hole 4, the burden on the root portion of the hair material 6 is reduced, and the durability is improved.
On the other hand, in the conventional cleaning brush (see FIG. 15B), the hair material 106 is directly planted on the base plate 102 made of a relatively hard resin, so that the burden on the root portion of the hair material 106 is large. ..

Further, in this embodiment, the divided sheet 5 is formed in a fan shape in a plan view. As a result, the split sheet 5 and the hair material 6 can be arranged on the base plate 2 with the minimum necessary gap in the circumferential direction. Therefore, the tire 21 and the wheel 22 can be effectively cleaned.

Further, in this embodiment, a fall prevention wall 10 is erected on the outer edge of the surface of the divided sheet 5. As a result, even if the hair material 6 is relatively strongly pressed against the tire 21 and the wheel 22, the fall prevention wall 10 prevents the hair material 6 from falling outward and spreading too much.
On the other hand, in the conventional cleaning brush (see FIG. 15B), a short and hard bristle material 106a is planted on the outermost peripheral side of the base plate 102 to prevent the bristle material 106 from collapsing. Therefore, it is necessary to transplant hair material 106a that is not for cleaning.

Further, in this embodiment, the holding cylinder 11 is raised on the surface of the divided sheet 5. As a result, the holding cylinder 11 holds the bristle material 6 in an appropriate posture. Therefore, the tire 21 and the wheel 22 can be effectively cleaned.

Further, in this embodiment, a plurality of protrusions 12 that come into contact with the front surface of the base plate 2 are provided on the back surface of the divided sheet 5. As a result, a storage space for the yarn 14 that holds the hair member 6 is formed between the back surface of the split sheet 5 and the front surface of the base plate 2.

Further, in this embodiment, the hair material 6 includes a hair material 6b for a wheel, and the hair material 6b for a wheel is a hair material 16a for the first wheel and a hair material 16a for the first wheel, which is shorter than the hair material 16a for the first wheel. The hair material 16b and the like are provided. As a result, the outside of the wheel 22 is effectively cleaned by the hair material 16a for the first wheel, and the inside of the wheel 22 is effectively cleaned by the hair material 16b for the second wheel, which is shorter than the hair material 16a for the first wheel. To be washed.

It should be noted that the present invention is not limited to the above-mentioned examples, and various modifications can be made within the scope of the present invention based on the purpose and application. That is, in the above embodiment, when the hair material 6 is damaged or the like, only the brush structure 3 is replaced to reuse the base plate 2, but the present invention is not limited to this, and for example, together with the brush structure 3. The base plate 2 may also be replaced.

Further, in the above embodiment, the resin base plate 2 has been illustrated, but the present invention is not limited to this, and for example, a metal base plate 2 such as aluminum may be used.
Further, in the above embodiment, the divided sheet 5 made of an elastic material has been illustrated, but the present invention is not limited to this, and for example, the divided sheet 5 made of resin may be used.

Further, in the above embodiment, the fan-shaped divided sheet 5 has been illustrated, but the present invention is not limited to this, and for example, the divided sheet 5 may be a rectangular, circular, elliptical, rhombus, or irregular shape.

Further, in the above embodiment, a form (see FIG. 14A) including two types of hair materials 16a and 16b for wheels having different lengths has been illustrated, but the present invention is not limited to this, and for example, FIG. 14B As shown in FIG. 14C, three types (or three or more types) of hair materials 16a to 16c for wheels having different lengths are provided, or as shown in FIG. 14C, for one type of wheel having the same length.
