Abstract

<P>PROBLEM TO BE SOLVED: To provide a toothbrush capable of easily removing plaque and tartar from one's teeth by enabling the force from the part serving as the point of effort to be applied most efficiently to the teeth when the toothbrush is always applied on teeth serving as the point of action at a right angle. <P>SOLUTION: The bristles of this toothbrush are shaped almost like a cone by being provided with a flat center bundle and by providing the gently-sloping skirts on all sides so as to structurally reinforce the periphery, so that the tips of the top bristles can closely fit into narrow slots or dents behind incisor teeth, which prevents this bundle from easily opening or bending sideways by the supporting of bristles constituting the peripheral skirt to ensure an efficient brushing effect. <P>COPYRIGHT: (C)2010,JPO&INPIT

タフト歯ブラシTuft toothbrush

現在市販されている歯ブラシは三角形タフト、山切りカット、蒲鉾形、ドーム形、楔形、極細テーパーカット、一束タフトなどがあるがどの形状もある一部には良く当てはまるが歯の裏側の数ミリメートル程度のくぼみや歯間部の各部の誤差にピタット当てはまらない。    Currently available toothbrushes include triangular tufts, angle cuts, saddle-shaped, dome-shaped, wedge-shaped, ultra-fine taper cuts, bundle tufts, etc. It does not apply to the degree of indentation or errors in each part of the interdental part.

作用点となる歯に直角に常にあたれば、力点となる部分の力が歯に最大の効率であたり歯垢や歯石を容易に除去できる。If it always hits the tooth that is the point of action at a right angle, the force of the part that becomes the point of power hits the tooth with maximum efficiency, and plaque and tartar can be easily removed.

上記（０００３）記載の種々の形状には次のような問題点を解決できずにいる。
すなわち三角形タフトでは三角に切ったために、歯間部の奥に入れなくなるし、門歯の裏では毛先が点でしか当たらず、効率が悪いし、腰がなくすぐに毛が開いてしまう。山切りカット歯間に入りそうであるが、この間隔あらゆる歯列に的確に合うことが稀である。蒲鉾形中央部が咬合面の谷間になだらか過ぎて、かえってフィットしない。楔形も蛇行する歯周溝には入りにくく、矯正中のワイヤーの中に入りやすく見えるが、歯の接合部分の部品を検出できず、入りにくい。平たんに丸加工も咬合面の凹面にフィットし難い。極細テーパーカットは先が細く一見溝やくぼみに入りやすく見えるが毛がばらついて一箇所に集中し難く必ずしも歯周溝や門歯の裏側に腰の強いあたりが出来ない。一束タフトもある程度当たるが腰がなくすぐに開いてしまう欠点を持つ。The various problems described in (0003) cannot solve the following problems.
In other words, since the triangular tuft is cut into a triangle, it cannot be inserted into the back of the interdental portion, and the tip of the hair hits only at the point on the back of the incisor, the efficiency is low, and the hair opens quickly without a waist. It is likely that it will fall between the cut teeth, but this interval is rarely suitable for every dentition. The saddle-shaped central part is too gentle in the valley of the occlusal surface, so it does not fit. The wedge shape is also difficult to enter into the meandering groove meandering, and it seems easy to enter into the wire being corrected, but it is difficult to detect the part of the joint of the tooth because it cannot be detected. Flat and round processing is difficult to fit on the concave surface of the occlusal surface. The ultra-fine taper cut looks narrow and easy to enter into grooves and dents, but it is difficult to concentrate in one place because the hairs are scattered and the back of the periodontal groove or incisor does not necessarily have a strong back. A bunch of tufts hits to some extent, but it has the disadvantage that it does not sit down and opens quickly.

中央部に平坦な束を設けその周りを構造補強するように四方からなだらかな裾野のような傾斜を設けることによって富士山状の構成となり、細い溝や細いくぼみ（門歯の裏のくぼみ）に山頂状の毛先がピタットフィットし、この束を周りの裾野を構成する植毛群の支えですぐに倒れたり、開いたりし難くなり、効率のよいブラシイング効果を引き出せるようになった。A flat bunch at the center and a slope like a gentle skirt from the four sides to reinforce the structure around it, resulting in a Mt. Fuji structure, with a narrow groove and narrow recess (indentation on the back of the incisor) at the top. The tip of the hair of the hair is fitted with a pitat fit, and it becomes difficult for the bundle to fall down and open easily with the support of the flocks that make up the surrounding skirt, so that an efficient brushing effect can be brought out.

前述の富士山状のブラシを植毛したブラシを梃子の原理を利用して、富士山状の毛先が歯の裏側のくぼみや歯間部の形に形状的にも、動的な運動中にもくぼみの底やふちにもピッタト密着しやすく、また歯間部の深部から入り口までも当たるように動くのでその接触点を作用点（１）として、手で保持する筒（５）上の点、力点（７）に加えられた手の力が筒（５）の下で自在に回転するように柄（３）のもう一方の先端部に設けたストッパー（６）を回転軸の支点（８）として、自在に回転して止まる構造を持った回転自在歯ブラシに応用した。Using the principle of eggplant, the brush with the Mt.Fuji brush implanted in the shape of the Mt. It is easy to fit tightly on the bottom and the edge of the tube, and also moves from the deep part of the interdental part to the entrance, so that the contact point is the point of action (1), the point on the cylinder (5) that is held by hand, the power point A stopper (6) provided at the other tip of the handle (3) so that the hand force applied to (7) can freely rotate under the cylinder (5) is used as a fulcrum (8) of the rotating shaft. It was applied to a rotatable toothbrush with a structure that freely rotates and stops.

この発明によって、歯の裏のくぼみや歯間を確実に捉えること出来るとともに、毛先の力が格段の力と持続力を持つことによって格段の清掃効果を引き出し、更にこのブラシを梃子の原理利用した上記回転自在歯ブラシに応用することによって、直角に当てることができ、最大の効率下で簡単に歯垢や歯石を除去できるようになった。By this invention, it is possible to surely capture the indentation and the gap between the teeth, and the hair end force has extraordinary power and lasting power, thereby drawing out a remarkable cleaning effect. By applying to the above-mentioned rotatable toothbrush, it can be applied at a right angle, and plaque and tartar can be easily removed under maximum efficiency.
