Abstract

PROBLEM TO BE SOLVED: To provide a spring brush capable of completely cleaning even a recessed part without applying excessive force even in the case that an object is recessed and projected without generating a cleaning leftover generated by the bending of brush bristles while hardly deforming the brush bristles and damaging the object. SOLUTION: All the brush bristles 2 flocked to a base 1 are respectively provided so as to make the tips of the brush bristles vertical to the base through bend parts 3 at one or two parts. Thus, each brush bristle is provided with an independent spring function, and at the time of use, the brush bristles are freely bent and stretched and the tips of the brush bristles reach all over the object.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spring brush in which each of the bristles can bend and extend independently and freely, so that the tip of the bristles can reach every corner of an object.

[0002]

2. Description of the Related Art Conventionally, when a brush is used, the brush bristles do not have flexibility and extensibility, and when the object has irregularities, the tip of the brush bristles does not reach the recess as it is. I had to.
In addition, when pressed and cleaned, the brush bristles other than the brush bristles that have reached the recess have an excess length, so they are curved along the surface, and there is a blank area around the recess where the brush bristles do not touch, leaving behind the cleaning. This causes the brush bristles to deform and remain bent over time. Further, an extra force is applied, so that the target object is easily damaged. In addition, a brush made of a hard material such as a wire is particularly poor in flexibility and has a remarkably poor restoring force. Other brushes with a spring function already exist, but the ones up to now are complicated in structure and easy to accumulate dirt. The biggest drawback is that the brushes are not brushed one by one and are planted in groups. Since it only bounces in bundles, it is doubtful that the effect of the spring actually reaches every corner of the object.

[0003]

This has the following disadvantages. I. If the object has irregularities because the brush bristles do not have flexibility, the tip of the brush bristles does not reach the concave portion as it is, so it has been necessary to apply a large force to press and clean the bristles. B. When pressed and cleaned, the brush bristles other than the brush bristles that have reached the recess have an excess length, so they are curved along the surface, and there is a blank area around the recess where the brush bristles do not touch, leaving behind the cleaning. Caused. C. The brush bristles will deform and remain bent over time when used with the brush pressed. D. When an extra force is applied, the target object is easily damaged. E. A brush made of a hard material such as a wire is particularly inflexible and has a remarkably poor restoring force. The present invention has been made to solve the above drawbacks.

[0004]

Means for Solving the Problems All of the brush bristles (2) planted on the base (1) are connected to the base (1) through one or two bent portions (3). 1) The brush bristles (2) each have an independent spring function by being provided so as to be perpendicular to the 1), and when a force is applied, the bent portion (3) can be freely bent and stretched. The tip of each brush bristles (2) is made to reach every corner of the object. The present invention is a spring brush having the above configuration.

[0005]

Embodiments of the present invention will be described below. I. Each of the bristles (2) of the base (1) has two bent portions (3) in the oblique direction and the vertical direction when the flocked portion (4) is perpendicular to the base, and the flocked portion (4) has When it is oblique to the base (1), one bent portion (3) is provided in the vertical direction. B. The closer the bent portion (3) is to the base (1) relative to the entire length of the brush bristles (2), the more the stability of the brush bristles (2) increases. C. In the bent portion (3), the effect of the brush bristles (2) increases as the degree of bending of the oblique portion increases, and conversely, as the degree of bending of the oblique portion decreases and approaches the linear shape, the brush bristles (2) increase. The effect of 2) increases the hardness. D. In the bent portion (3), the longer the section in the oblique or horizontal direction relative to the entire length of the brush bristles (2), the greater the bending width and the greater the action of the brush bristles (2),
Conversely, the shorter the section in the oblique or horizontal direction relative to the entire length of the brush bristles (2), the smaller the bending width and the harder the action of the brush bristles (2). E. The bent portion (3) is considered in consideration of the above (2), (3) and (3),
What is necessary is just to set so that each brush bundle (6) does not hinder each other's bending and extension movement, and the position and direction of the bent part (3) may be the same or different. F. As a result, each brush bristle (2) has an independent spring function. G. When a force is applied, the bent portion (3) bends and stretches, so that each brush bristles (2)
However, it has independent spring function so that every corner of the property can be thoroughly cleaned. The present invention has the above configuration. When the present invention is used, the brush bristles (2) each having a bent portion (3) have an independent spring function, so that even if the object has irregularities, the brush bristles (2) require only a small force. The bent portion (3) of the brush bristles freely bends and extends, so that the tip of the brush bristles reaches the concave portion, and can be easily and completely cleaned. In addition, the brush bristles other than the brush bristles that arrived at the recess, such as when pressed with a large force and cleaned, are curved along the surface due to excess length, and there is a blank portion around the recess where the tip of the brush bristles does not hit. No cleaning residue occurs. Further, the brush bristles are hardly deformed, and the object is hardly scratched because no extra force is applied.

[0006]

[Other Embodiment] In the embodiment shown in FIG. 6, the diagonal portion of the bent portion (3) of the brush bristles (2) is made horizontal to enhance flexibility.

[0007] The embodiment shown in FIG.
With a hand brush planted so that the bent portion (3) becomes radial, an even effect can be obtained over a wide range.

[0008] The embodiment shown in FIG.
The toothbrush planted so that the bent portion (3) of the toothbrush faces a different angle. The brush bristles make a uniform movement in which the force is not biased in only one direction with respect to the front-back and left-right movement of the toothbrush. Random movement for brush hair.

[0009] The embodiment shown in FIG.
The curved part (3) is not a broken line but a curved brush.
The spring effect is slightly inferior to that of the folding line, but the softness in the front, rear, left and right directions has been increased.

In the embodiment shown in FIG. 10, the flexibility is doubled by repeating the bent portion (3) of the brush bristles (2) a plurality of times.

The embodiment shown in FIG. 11 is a wire brush in which the bent portion (3) of the brush bristles (2) is formed in a spiral shape instead of a broken line. Great flexibility for

[0012]

The present invention is embodied in the form described above and has the following effects. I. Even when the object has irregularities when using a brush, each brush bristle has an independent spring function, so that the tip can reach the concave portion without any extra force and can be completely cleaned. Since it is not pressed forcefully, there is no cleaning residue caused by bending of the brush bristles. B. Prevents deformation of the brush bristles and makes it difficult for the object to be scratched. C. It is possible to give spring properties and flexibility to brush bristles made of hard material such as wire. D. The structure is simple, the application range is wide, and the spring strength can be variously adjusted according to the material of the brush bristle.
