Abstract

PROBLEM TO BE SOLVED: To shorten the time required for removing the mud on an irregular face in a case when a brush is applied as a brush for washing a vehicle, by mounting plural sets of bundles of bristles on a head face of a brush at suitable intervals, and burying groups of bundles of bristles into the head face in a condition that plural pieces of bundles of bristles are independently inclined in the different directions. SOLUTION: Plural sets of the groups of bundles of bristles 3 are arranged on a head face 2 of a brush 1 at suitable intervals, and the bundle of bristles 3a which is located on a center of the group of bundles of bristles 3 comprising the bundles of bristles 3a, 3b, 3c, is vertically buried in the head face 2. Further plural bundles of bristles 3b are buried on a circle (b) of the first concentric circle on the bundle of bristle 3a in such manner that they have a specific inclination to the head face 2, and they are spirally inclined. The points of the bristles of the bundles of bristles 3a, 3b, 3c are projected in multidirections, so that one of bundles of bristles reaches a corner of the irregular part when the brush 1 is pressed to the irregular part such as a tread part of a tire or the like, to rub the same with the brush, whereby the mud on the tire can be removed for a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush, and more particularly to a brush for washing a car.

[0002]

2. Description of the Related Art In conventional car wash brushes, all of the bristles of the brush are implanted perpendicular to the head surface.

[0003]

The conventional brush for car washing is good for cleaning a flat surface such as an automobile body or a glass surface, but is not suitable for cleaning an uneven surface such as a tread portion of a tire or a fender. The tip does not bite into the concave enough,
There was a problem that it took time to remove the mud.

[0004] It is an object of the present invention to solve these problems and to provide a brush for car washing capable of strongly cleaning an uneven surface.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a brush in which a plurality of sets of bristle bundles are arranged at appropriate intervals on the head surface of the brush. Is characterized in that a plurality of bristle bundles are formed in such a manner that the plurality of bristle bundles are independently and mutually inclined in different directions and are planted on the head surface.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As a first embodiment of the present invention, an example in which the present invention is applied to a car wash brush is shown in FIGS.
Shown in

On the head surface 2 of the brush 1, a plurality of hair bundle groups 3 are arranged at appropriate intervals.

Reference numerals 3a, 3b and 3c denote hair bundles, respectively, and the hair bundle 3a located at the center of the hair bundle group 3 is planted perpendicularly to the head surface 2.

On a first concentric circle line b centered on the hair bundle 3a, a plurality of hair bundles 3b have a predetermined inclination angle with respect to the head surface 2 and form a spiral. Flocked with inclination. Also, on the second concentric circle line c, a plurality of bristle bundles 3c are also implanted with a predetermined inclination angle with respect to the head surface 2 and spirally inclined.

The size of the circles b and c and the number of hair bundles 3b... 3c implanted on the circles b and c are appropriately selected according to the required brush stiffness. Is done.

The hair bundles 3b, 3b
The inclination angle at the time of planting c may be appropriately selected. For example, if the plant is planted at an angle of 85 to 75 degrees with respect to the head surface 2, it is effective for mud dropping of the tire.

Next, the operation and effect of the car wash brush according to the first embodiment will be described.

In the present car wash brush 1, since the hair bundles 3a, 3b and 3c constituting the hair bundle group 3 protrude from the hair tips in multiple directions, the car wash brush 1 is provided on uneven portions such as a tread portion of a tire. When the brush 1 is pressed and rubbed, any one of the bristle bundles easily reaches the corners of the uneven portion and performs cleaning, so that the tire can be removed in a short time. .

In the present embodiment, the circular line is constituted by double concentric circle lines b and c. However, this is a single circle, a concentric circle of three or more times, or a spiral. It may be composed of a curve.

As a second embodiment of the present invention, an example in which the present invention is applied to a toothbrush is shown in FIGS.

On the head face 5 of the toothbrush 4, a plurality of sets of bristle bundles 6 are arranged at appropriate intervals.

The hair bundle 6a located at the center of the hair bundle group 6 is planted perpendicularly to the head surface 5, and
A plurality of hair bundles 6d are placed on a circle d around the hair bundle 6a.
However, the hairs are implanted with a predetermined inclination angle with respect to the head surface 5 and spirally inclined.

Next, the operation and effect of the toothbrush of the second embodiment will be described.

In the present toothbrush 4, since the hair bundles 6a and 6d constituting the hair bundle group 6 protrude in the bristles in multiple directions, the conventional toothbrush 4 consists only of the bristle bundle which is implanted perpendicularly to the head surface of the toothbrush. As compared to a toothbrush, the bristle tip can easily enter the interdental area, plaque and food debris can be removed quickly and the teeth can be cleaned, and the gingival part can be massaged with moderate rigidity. It is also effective in preventing and treating pyorrhea.

In this embodiment, the hair bundle group 6 is formed by implanting four hair bundles 6d per each hair bundle group 6 at an inclination angle of 85 degrees with respect to the head surface 5. But,
In this case, the number of the hair bundles 6d in each hair bundle group 6 may be other than four, and the inclination angle of the hair bundles 6d may be an angle other than 85 degrees.

[0021]

As described above, according to the present invention, when the present invention is applied to a car wash brush, it is possible to reduce the time required for removing mud on an uneven surface such as a tread portion of a tire and to apply the present invention to a toothbrush. In this case, plaque and food debris can be removed quickly, and it is also effective in preventing and treating alveolar pyorrhea.
