図２に示すように、歯根用歯ブラシ１００は、主に歯根を磨くものであり、細長い柄１と、柄１の端部に設けられるヘッド４と、ヘッド４に配列されて植毛される複数の細長の弾性毛３とを備える。   As shown in FIG. 2, the toothbrush 100 for a root is mainly used for brushing the root, and includes a long and narrow handle 1, a head 4 provided at an end of the handle 1, and a plurality of hairs arranged and planted in the head 4. Elongated elastic bristles 3 are provided.

柄１は、断面が扁平で、全体が長細い棒状体であり、柄１の一端側にある柄本体１１と、柄１の他端側にあり、柄本体１１の長手方向の軸Ａに対して折曲部２で略４５度に折れ曲がってヘッド軸Ｂに沿って延在する延在部１２と、柄本体１１と折曲部２との間にあるネック部１３と、ネック部１３と柄本体１１との間にあり、柄１の表側面に設けられた滑り止め凸部１４と、柄１の裏側面に設けられた滑り止め凹部１５と、を備える。   The handle 1 is a rod-like body having a flat cross section and a long thin body as a whole. The handle body 11 is located on one end side of the handle 1 and the other end side of the handle 1. The bent portion 2 is bent at approximately 45 degrees and extends along the head axis B, the neck portion 13 between the handle body 11 and the bent portion 2, the neck portion 13 and the handle. It is located between the main body 11 and includes a non-slip convex portion 14 provided on the front side surface of the handle 1 and an anti-slip concave portion 15 provided on the back side surface of the handle 1.

ヘッド４は、延在部１２に連なり、柄１の軸Ａに対して略４５度の角度で傾斜するヘッド軸Ｂに沿う細長平板状体であり、ヘッド４の表側面及び裏側面には弾性毛３が植毛されている。   The head 4 is an elongated flat plate body that extends along the head axis B that is connected to the extending portion 12 and is inclined at an angle of about 45 degrees with respect to the axis A of the handle 1. The hair 3 is planted.

図４に示すように、ヘッド４の表側面には傾斜面４ａがあり、傾斜面４ａの法線方向の軸Ｃは、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとが成す平面に対して所定の角度γだけ傾斜している。つまり、ヘッド４の表側面には、ヘッド軸Ｂと柄１の軸Ａとが成す平面に垂直な面に対して、角度γのテーパが設けられる。
そして、傾斜面４ａには弾性毛３ａが植毛されており、弾性毛３ａは、傾斜面４ａに対して垂直に設けられ、弾性毛３ａの軸Ｃは、傾斜面４ａの法線方向の軸Ｃと一致しており、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとを含む平面に対して所定の角度γだけ傾斜している。 As shown in FIG. 4, there is an inclined surface 4a on the front side surface of the head 4, and the normal axis C of the inclined surface 4a is the axis of the head axis B and the handle 1 when viewed from the head axis B direction. It is inclined by a predetermined angle γ with respect to the plane formed by A. That is, a taper having an angle γ is provided on the front side surface of the head 4 with respect to a plane perpendicular to the plane formed by the head axis B and the axis A of the handle 1.
And the elastic hair 3a is planted in the inclined surface 4a, the elastic hair 3a is provided perpendicular | vertical with respect to the inclined surface 4a, and the axis | shaft C of the elastic hair 3a is the axis C of the normal line direction of the inclined surface 4a. And is inclined by a predetermined angle γ with respect to a plane including the head axis B and the axis A of the handle 1 when viewed from the head axis B direction.

また、ヘッド４の裏側面にも傾斜面４ｂがあり、傾斜面４ｂの法線方向の軸Ｄは、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとが成す平面に対して所定の角度δだけ傾斜している。つまり、ヘッド４の裏側面には、ヘッド軸Ｂと柄１の軸Ａとが成す平面に垂直な面に対して、角度δのテーパが設けられる。
そして、傾斜面４ｂには弾性毛３ｂが植毛されており、弾性毛３ｂは、傾斜面４ｂに対して垂直に設けられ、弾性毛３ｂの軸Ｄは、傾斜面４ｂの法線方向の軸Ｄと一致しており、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとを含む平面に対して所定の角度δだけ傾斜している。 Further, the back surface of the head 4 also has an inclined surface 4b, and the axis D in the normal direction of the inclined surface 4b is a plane formed by the head axis B and the axis A of the handle 1 when viewed from the head axis B direction. Is inclined by a predetermined angle δ. That is, a taper having an angle δ is provided on the back side surface of the head 4 with respect to a plane perpendicular to the plane formed by the head axis B and the axis A of the handle 1.
And the elastic hair 3b is planted in the inclined surface 4b, the elastic hair 3b is provided perpendicularly to the inclined surface 4b, and the axis D of the elastic hair 3b is the axis D in the normal direction of the inclined surface 4b. And is inclined by a predetermined angle δ with respect to a plane including the head axis B and the axis A of the handle 1 when viewed from the head axis B direction.

さらに、ヘッド４の表側面に設けられた弾性毛３ａの軸Ｃ方向と、前記裏側面に設けられた弾性毛３ｂの軸Ｄ方向とは異なっている。つまり、ヘッド４の表側面に備わる傾斜面４ａの法線方向Ｃと、前記ヘッドの裏側面に備わる傾斜面４ｂの法線方向Ｄとは、異なっている。
このように、軸Ｃが傾斜する角度γと軸Ｄが傾斜する角度δとを敢えて異なる角度とすることで、歯根に対して弾性毛３を二方向から当てることができ、歯根を満遍なく磨くことができる。 Furthermore, the direction of the axis C of the elastic bristles 3a provided on the front side surface of the head 4 is different from the direction of the axis D of the elastic bristles 3b provided on the back side surface. That is, the normal direction C of the inclined surface 4a provided on the front side surface of the head 4 is different from the normal direction D of the inclined surface 4b provided on the back side surface of the head.
In this way, the angle γ at which the axis C is inclined and the angle δ at which the axis D is inclined are different from each other, so that the elastic bristles 3 can be applied to the tooth root from two directions, and the tooth root is polished evenly. Can do.

弾性毛３は、樹脂製の棒状体であり、先端が窄まるとともに丸みを帯びており、ヘッド４の表面に対して垂直に設けられ、ヘッド４の表側面及びヘッド４の裏側面の両面に設けられる。

Below, an example of how to polish the root using the toothbrush 100 for a root is given. This example is only an example.
(1) To polish the root using the toothbrush 100 for a root as described above, first, grip the handle 1 with one hand and insert the axis A of the handle 1 into the oral cavity with the head 4 facing the mouth. The head 4 is inserted into the oral cavity while maintaining it.
At that time, the bending direction of the bent portion 2 is set to a substantially horizontal direction so as to face the inner surface of the lower left tooth, for example.
(2) While pressing the elastic bristles 3a planted on the front side of the head 4 against the surface of the lower left tooth, the handle 1 is reciprocated in the direction of insertion into the oral cavity. As a result, the elastic bristles 3a hitting the tooth surface are guided in the direction of the tooth root, so that the boundary from the tooth surface to the tooth root can be appropriately polished without damaging the gums. The axis A of the handle 1 may be slightly inclined with respect to the direction in which the handle 1 is inserted into the oral cavity.
(3) Next, while maintaining the bending direction of the bent portion 2, the axis A of the handle 1 is moved horizontally, and the elastic bristles 3 b planted on the back side surface of the head 4 are the inner side surfaces of the lower right teeth. To face.
(4) Then, the elastic bristles 3b planted on the back side of the head 4 are reciprocated in the direction in which the handle 1 is inserted into the oral cavity while pressing against the surface of the lower right tooth.
(5) Subsequently, in order to polish the upper root, the axis A of the handle 1 is rotated 180 degrees so that the bending direction of the bent portion 2 is opposed to the inner surface of the upper right tooth, and the substantially horizontal direction. To.
(6) While pressing the elastic bristles 3a planted on the front side of the head 4 against the surface of the upper right tooth, the handle 1 is reciprocated in the direction of insertion into the oral cavity.
(7) Next, with the bending direction of the bent portion 2 maintained, the axis A of the handle 1 is moved horizontally, and the elastic bristles 3b planted on the back side surface of the head 4 are placed on the inner side surface of the upper left tooth. Try to face each other.
(8) Then, the elastic bristles 3b planted on the back side surface of the head 4 are reciprocated in the direction in which the handle 1 is inserted into the oral cavity while pressing against the upper left tooth surface.
In this way, the root can be easily polished.

以上、本発明の好ましい実施例について詳述したが、本発明に係る歯根用歯ブラシは上述した実施形態に限定されるものではなく、特許請求の範囲に記載された本発明の要旨の範囲内において、種々の変形、変化が可能である。   As mentioned above, although the preferred Example of this invention was explained in full detail, the toothbrush for roots based on this invention is not limited to embodiment mentioned above, In the range of the summary of this invention described in the claim Various modifications and changes are possible.

例えば、上記の実施形態においては、ヘッド４の表側面に設けられた弾性毛３ａの軸Ｃ方向と、ヘッド４の裏側面に設けられた弾性毛３ｂの軸Ｄ方向が、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとを含む平面に対して所定の角度γ又はδだけ傾斜するものを説明したが、これに限らず、ヘッド４の表側面に設けられた弾性毛３ａの軸Ｃ方向とヘッド４の裏側面に設けられた弾性毛３ｂの軸Ｄ方向の一方のみが、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとを含む平面に対して所定の角度δだけ傾斜するものとしてもよい。   For example, in the above embodiment, the axis C direction of the elastic bristles 3a provided on the front side surface of the head 4 and the axis D direction of the elastic bristles 3b provided on the back side surface of the head 4 are from the head axis B direction. In the above description, the head is inclined by a predetermined angle γ or δ with respect to a plane including the head axis B and the axis A of the handle 1. When only one of the direction C of the elastic bristles 3a and the direction D of the elastic bristles 3b provided on the back side of the head 4 is viewed from the direction of the head axis B, the head axis B and the axis A of the handle 1 are It may be inclined by a predetermined angle δ with respect to the plane including the surface.

本発明によれば、ヘッド４が、柄１の軸Ａに対して略４５度の角度で傾斜するヘッド軸Ｂに沿う細長平板状体であるので、歯根用歯ブラシ１００を、柄１の軸Ａを口腔に挿通する方向からあまり大きく傾けなくても、弾性毛３の軸Ｃが歯の奥の面を向き、歯をくまなく磨き易い。   According to the present invention, since the head 4 is an elongated flat plate body along the head axis B inclined at an angle of about 45 degrees with respect to the axis A of the handle 1, the toothbrush 100 for the root is attached to the axis A of the handle 1. Even if it is not tilted so much from the direction of inserting the hair into the oral cavity, the axis C of the elastic bristles 3 faces the back surface of the teeth, and it is easy to brush all over the teeth.

本発明によれば、ヘッド４の表側面及び裏側面には弾性毛３が植毛されているので、例えば、ヘッド４の表側面に植毛された弾性毛３ａで左下の歯の内側を磨いた後に、柄１の軸Ａを回転させずにそのままの姿勢で歯根用歯ブラシ１００を右下の歯の内側に移動し、右下の歯の内側を磨けたり、柄１の軸Ａを９０度回転させた状態で上下の歯を同時に磨けたりするので、手の負担が軽減され、歯を磨き易い。   According to the present invention, the elastic hairs 3 are planted on the front side surface and the back side surface of the head 4. For example, after brushing the inside of the lower left tooth with the elastic hair 3 a planted on the front side surface of the head 4. Move the root toothbrush 100 to the inside of the lower right tooth without rotating the axis A of the handle 1 and polish the inside of the lower right tooth, or rotate the axis A of the handle 1 by 90 degrees. Since the upper and lower teeth can be brushed at the same time, the burden on the hands is reduced and the teeth are easy to brush.

本発明によれば、弾性毛３ａの軸Ｃ及び弾性毛３ｂの軸Ｄは、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとを含む平面に対して角度γ又は角度δだけ傾斜するので、歯根用歯ブラシ１００を、柄１の軸Ａを口腔に挿通する方向からあまり大きく傾けず、柄１の表側面が歯の表面に対して平行になるような姿勢で手に持つと、弾性毛３の軸Ｃが歯根の方向に向き、その姿勢で歯の表面に弾性毛３ａを押し当てて柄１の軸Ａの方向に往復させるだけで、歯の表面を磨くのみならず、歯茎を傷つけずに歯根を適切に磨くことができる。   According to the present invention, the axis C of the elastic bristles 3a and the axis D of the elastic bristles 3b have an angle γ with respect to a plane including the head axis B and the axis A of the handle 1 when viewed from the head axis B direction. Since the toothbrush 100 for the root is not inclined so much from the direction in which the axis A of the handle 1 is inserted into the oral cavity, the hand is held in such a posture that the front side of the handle 1 is parallel to the tooth surface. The axis C of the elastic bristles 3 is oriented in the direction of the root of the tooth, and in this posture, the elastic bristles 3a are pressed against the surface of the teeth and reciprocated in the direction of the axis A of the handle 1. In addition, the roots can be properly polished without damaging the gums.

本発明によれば、弾性毛３ａの軸Ｃ及び弾性毛３ｂの軸Ｄは、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとを含む平面に対して角度γ又は角度δだけ傾斜するので、歯根用歯ブラシ１００を、柄１の表側面が歯の表面に対して平行になるような姿勢で手に持ち、歯根用歯ブラシ１００を歯の表面に向けて押圧すると、歯の表面に対して弾性毛３の軸Ｃ又は軸Ｄが垂直に当たらず、若干斜めに当たるので、歯の表面に当たった弾性毛３が歯根の方向に誘導され、歯茎を傷つけずに歯の表面から歯根に至る境界を適切に磨くことができる。   According to the present invention, the axis C of the elastic bristles 3a and the axis D of the elastic bristles 3b have an angle γ with respect to a plane including the head axis B and the axis A of the handle 1 when viewed from the head axis B direction. Since the toothbrush 100 for the root is held in a hand such that the front side of the handle 1 is parallel to the tooth surface, and the toothbrush 100 for the root is pressed toward the tooth surface, since the angle δ is inclined, Since the axis C or axis D of the elastic bristles 3 does not hit the surface of the teeth perpendicularly but rather at an angle, the elastic bristles 3 hitting the tooth surface are guided in the direction of the roots of the teeth without damaging the gums. The boundary from the surface to the root can be properly polished.

本発明によれば、弾性毛３ａの軸Ｃ及び弾性毛３ｂの軸Ｄは、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとを含む平面に対して角度γ又は角度δだけ傾斜するので、歯根用歯ブラシ１００を押圧する力は、歯の表面方向に全てかからず、歯根の方向にも分配され、歯の表面を傷つけることを抑制できるとともに、歯の表面と歯根の両方を磨くことができる。   According to the present invention, the axis C of the elastic bristles 3a and the axis D of the elastic bristles 3b have an angle γ with respect to a plane including the head axis B and the axis A of the handle 1 when viewed from the head axis B direction. Since the angle δ is inclined, the force that presses the toothbrush 100 for the root is not applied in the direction of the surface of the tooth but is distributed also in the direction of the root of the tooth. Both roots can be polished.

本発明によれば、弾性毛３ａの軸Ｃ及び弾性毛３ｂの軸Ｄは、ヘッド軸Ｂ方向から視たときに、ヘッド軸Ｂと柄１の軸Ａとを含む平面に対して角度γ又は角度δだけ傾斜するので、歯を磨くときと歯根を磨くときとで軸Ａを中心にして柄１を回転する必要がなく、手に対する負担が少なく、使用者の歯磨き技術に依存することなく、歯根を磨き易い。   According to the present invention, the axis C of the elastic bristles 3a and the axis D of the elastic bristles 3b have an angle γ with respect to a plane including the head axis B and the axis A of the handle 1 when viewed from the head axis B direction. Since it is inclined by the angle δ, it is not necessary to rotate the handle 1 around the axis A when brushing the teeth and when brushing the roots, there is less burden on the hand, and it does not depend on the user's tooth brushing technology, It is easy to brush the roots.

本発明によれば、ヘッド４の表側面に設けられた弾性毛３ａの軸Ｃ方向と、前記裏側面に設けられた弾性毛３ｂの軸Ｄ方向とは異なるので、柄１を１８０度反転させることで歯根に対して弾性毛３を二方向から当てることができ、歯根を満遍なく磨くことができる。   According to the present invention, since the direction of the axis C of the elastic bristles 3a provided on the front side surface of the head 4 is different from the direction of the axis D of the elastic bristles 3b provided on the back side surface, the handle 1 is inverted 180 degrees. Thus, the elastic hair 3 can be applied to the tooth root from two directions, and the tooth root can be polished evenly.
