Description

この出願は歯ブラシに関し、特に上下の歯間に嵌挿して噛むことで歯を磨くマウスピース状の歯ブラシに関する。   This application relates to a toothbrush, and more particularly, to a mouthpiece-shaped toothbrush that brushes teeth by inserting and biting between upper and lower teeth.

従来の歯ブラシは、手で握る握り柄とその先のブラシ台にブラシを植毛したブラシ部であるヘッドからなり、この種の歯ブラシは、ブラシに練り歯磨きをつけ、口蓋内の上下の歯並びの周囲に差し入れ、柄を上下あるいは左右に繰り返し往復運動するブラッシングで、歯の表面、歯と歯茎の間の歯周ポケット、歯と歯の間のいわゆる歯間、あるいは歯茎などを磨いて清掃すると共に歯肉をマッサージするのが一般的である。この歯ブラシを用いてブラッシングすることにより虫歯を予防し、歯周病を防いだりする。この種の一般的な歯ブラシは、ブラシ台の長さや幅を小さくしたり、あるいは柄とブラシ台の角度を改変したり、若しくは、ブラシの毛先全体の形状を山形にしたり、ブラシの各毛または各毛先を細さを変えたりあるいは毛の硬さを変えたりするなど、種々の工夫を凝らしている。   Conventional toothbrushes consist of a grip handle that is gripped by hand and a head that is a brush part in which the brush is flocked to the tip of the brush stand. Brushing the handle repeatedly and reciprocating up and down or left and right, brushing and cleaning the tooth surface, periodontal pockets between teeth and gums, so-called teeth between teeth, or gums, and gums It is common to massage. Brushing with this toothbrush prevents cavities and prevents periodontal disease. This type of general toothbrush can reduce the length and width of the brush base, change the angle between the handle and the brush base, make the entire shape of the brush tip chevron, Or, various ingenuity has been devised, such as changing the thickness of each hair tip or changing the hardness of the hair.

一方、上記の従来の種々工夫を凝らした歯ブラシを使用しても、誤った使用方法では適切な歯磨きをすることはできない。このため正しいブラッシングの仕方や、またブラッシングをいつどのぐらいの頻度で行うのが大事であるかなどの注意が学校や、歯科医院などで呼びかけられ、指導されている。しかし、ブラッシングは健康のために必要な行為でありながら、生活のなかで、正しいブラッシングはついおろそかになり易く、ブラッシングをしても、必ずしも正しいブラッシングが実施されているとは限らず、虫歯や歯周病になってしまうことが多かった。   On the other hand, even if a conventional toothbrush with various ideas is used, proper toothbrushing cannot be performed by an incorrect usage method. For this reason, the school and dental clinics are calling and giving instructions on how to brush properly and when and how often it is important to brush. However, although brushing is an act necessary for health, correct brushing tends to be neglected in daily life, and even brushing does not always carry out correct brushing. Often suffered from periodontal disease.

一方、握り柄の先端部をブラシ台とする従来の歯ブラシに代えてマウスピース型のブラシ台とし、そのブラシ台に上下方向の毛を植えつけた歯ブラシが（例えば、特許文献１参照。）開発されている。さらにこれらのマウスピース型のブラシ台を電動モーターにより振動させるようにしたものが（例えば、特許文献２参照。）開発されている。さらにマウスピース型の台から超音波を付与した液体を噴出して洗いさるものが（例えば、特許文献３参照。）開発されている。   On the other hand, instead of a conventional toothbrush that uses the tip of the grip handle as a brush base, a mouthpiece type brush base is used, and a toothbrush in which vertical hairs are planted on the brush base is developed (see, for example, Patent Document 1). Has been. Further, those in which these mouthpiece type brush stands are vibrated by an electric motor have been developed (see, for example, Patent Document 2). Furthermore, what wash | injects and wash | cleans the liquid which gave the ultrasonic wave from the mouthpiece type stand (for example, refer patent document 3) is developed.

しかし、これらのマウスピース型のものはブラシ台などの形状の湾曲度が一定のものからなるもので、その湾曲度はそれぞれの使用者の歯並びの形状に合わせることができないものであった。   However, these mouthpiece types are composed of a brush table or the like having a constant degree of curvature, and the degree of curvature cannot be adapted to the shape of each user's teeth.

本発明の歯ブラシは、従来の歯ブラシと異なり、上下の歯並びの間に挿入して上下の歯で繰り返し噛む動作をすることで、歯の表裏や歯茎や歯間や歯茎と歯肉の間の歯周ポケットを本歯ブラシの毛先でブラッシングを可能とし、特に歯間や歯周ポケットを的確にブラッシングし、さらに、従来のマウスピース型の歯ブラシがその湾曲度が不変であったものを、本発明の噛む歯ブラシでは、マウスピース状のブラシ台の形状の湾曲度を口蓋の中の歯並びの大きさに合わせて自在に調整可能としたので、多くの人が使用可能な汎用性のあるマウスピース状の噛む歯ブラシとなり、ひいては大量生産によるコスト低減が図れるなど、本発明は従来にない優れた効果を奏するものである。   Unlike conventional toothbrushes, the toothbrush of the present invention is inserted between the upper and lower teeth and repeatedly bites with the upper and lower teeth, so that the periodontal between the front and back of the teeth, the gums, between the teeth, and between the gums and the gums. The pockets of the toothbrush can be brushed on the pockets, particularly the interdental and periodontal pockets are brushed accurately, and the conventional mouthpiece type toothbrush whose curvature has not changed is that of the present invention. With a chewing toothbrush, the degree of curvature of the shape of the mouthpiece-shaped brush base can be freely adjusted according to the size of the teeth in the palate, so it is a versatile mouthpiece-shaped that can be used by many people. The present invention provides an excellent effect that has not been achieved so far, such as a toothbrush to be chewed, and thus cost reduction by mass production.

本発明を実施するための最良の形態を図面を参照して説明する。本発明の手段の１実施の形態の噛む歯ブラシ１は、口蓋の中の湾曲した上顎の歯並びおよび下顎の歯並びに予めほぼ倣ってマウスピース状に湾曲しプラスチックス１６からなるブラシ台２を有する。このブラシ台２は上下の歯並びに対向した上向きのブラシ台２ａと下向きのブラシ台２ｂからなる一体物として形成されている。この上向きのブラシ台２ａと下向きのブラシ台２ｂにはそれぞれ上下の歯２１の方向にブラシの毛１７が植毛されているブラシ部３を有する。このブラシ部３は上側のブラシ部４と下側のブラシ部５からなっている。さらに、このブラシ台２の湾曲した外面６の中心部には使用時に手で握るための棒状の把持具７がブラシ台２の湾曲した外面６から背後に突出するように取り付けられている。さらに上下のブラシ台２ａ、２ｂはその湾曲度を口腔内の上下の歯並びの湾曲度に合わせて調整自在になるように形成されている。
なお、棒状の把持具７は、大きさや握り形状については保持しやすいように適宜変更してもよい。 The best mode for carrying out the present invention will be described with reference to the drawings. The biting toothbrush 1 according to an embodiment of the means of the present invention has a curved upper jaw teeth and lower jaw teeth in the palate, and a brush base 2 made of plastics 16 curved in a mouthpiece shape substantially in advance. The brush base 2 is formed as an integrated body composed of upper and lower teeth and opposing upward brush base 2a and downward brush base 2b. Each of the upward brush base 2a and the downward brush base 2b has a brush portion 3 in which brush hairs 17 are implanted in the direction of the upper and lower teeth 21. The brush portion 3 includes an upper brush portion 4 and a lower brush portion 5. Further, a rod-like gripping tool 7 for gripping with a hand during use is attached to the center of the curved outer surface 6 of the brush base 2 so as to protrude rearward from the curved outer surface 6 of the brush base 2. Further, the upper and lower brush bases 2a and 2b are formed so that the degree of curvature thereof can be adjusted according to the degree of curvature of the upper and lower teeth in the oral cavity.
In addition, you may change suitably the rod-shaped holding tool 7 so that it may be easy to hold | maintain about a magnitude | size and a grip shape.

さらに他の実施の形態では、この湾曲度を調整自在に形成しているブラシ台２は、上下対称形状のブラシ台２ａ、２ｂを有し、この上下対称のブラシ台２ａ、２ｂの間に、これらの上下のブラシ台２ａ、２ｂを支持するための湾曲した金属バネ材からなる板バネプレート１０を有する。この板バネプレート１０はさらにその板バネプレート１０の湾曲面の外側面の中心部に手指で握る棒状の把持具７の支軸８が取り付けられている。この湾曲した板バネプレート１０はマウスピース状の上下のブラシ台２ａ、２ｂの間でこれらと同様に湾曲しており、板バネプレート１０の湾曲した上下幅の中央部で硬質金属板１３の両端１４と当接する部分には部分的に板バネプレート１０の長手方向に開口した溝孔１２が形成されており、この溝孔１２に両端１４を滑動自在に嵌合した一定長さの硬質金属板１３が弦状に嵌合され拘束状態で係止されている。   In still another embodiment, the brush base 2 that is formed so that the degree of curvature is adjustable has vertically symmetrical brush bases 2a and 2b, and between the vertically symmetrical brush bases 2a and 2b, A plate spring plate 10 made of a curved metal spring material for supporting the upper and lower brush bases 2a and 2b is provided. The leaf spring plate 10 is further provided with a support shaft 8 of a rod-like gripper 7 that is gripped with a finger at the center of the outer surface of the curved surface of the leaf spring plate 10. The curved leaf spring plate 10 is curved similarly between the mouthpiece-like upper and lower brush bases 2a and 2b, and both ends of the hard metal plate 13 at the center of the curved vertical width of the leaf spring plate 10. A slot 12 that is partially open in the longitudinal direction of the leaf spring plate 10 is formed in a portion that contacts the slot 14, and a fixed-length hard metal plate in which both ends 14 are slidably fitted in the slot 12. 13 is fitted in a string shape and locked in a restrained state.

そして把持具７の支軸８にはネジ山が形成されており、この支軸８は板バネプレート１０の中央に設けられたネジ孔１１にネジ螺合されて貫通されている。さらに板バネプレート１０の中央をネジ螺合されて貫通された支軸８の先端部９は板バネプレート１０の内面に弦状に張られた硬質金属板１３の中央に形成の孔１５に回転自在に止着されている。従って、この把持具７を回転することにより、図３に実線と仮想線で示すように硬質金属板１３は板バネプレート１０の湾曲内で支軸８方向に前後に移動される。そこで板バネプレート１０は硬質金属板１３の一定長さの両端１４の間で拘束される結果、板バネプレート１０は硬質金属板１３に対して相対的に前後に移動して板バネプレート１０の湾曲度が変えられて自在に調整される。例えば、図４の（ａ）は板バネプレート１０の湾曲度を狭めた状態を示し、図４の（ｂ）は板バネプレート１０の湾曲度を広げた状態を示す。   A screw thread is formed on the support shaft 8 of the gripping tool 7, and this support shaft 8 is screwed into a screw hole 11 provided in the center of the leaf spring plate 10 and penetrated. Further, the tip 9 of the support shaft 8 threaded through the center of the plate spring plate 10 is rotated into a hole 15 formed in the center of the hard metal plate 13 stretched in a string shape on the inner surface of the plate spring plate 10. It is freely attached. Therefore, by rotating the gripping tool 7, the hard metal plate 13 is moved back and forth in the direction of the support shaft 8 within the curvature of the leaf spring plate 10 as indicated by a solid line and a virtual line in FIG. 3. Therefore, as a result of the plate spring plate 10 being constrained between both ends 14 of a certain length of the hard metal plate 13, the plate spring plate 10 moves back and forth relative to the hard metal plate 13, and the plate spring plate 10 The degree of curvature can be changed and adjusted freely. For example, FIG. 4A shows a state where the degree of curvature of the leaf spring plate 10 is narrowed, and FIG. 4B shows a state where the degree of curvature of the leaf spring plate 10 is widened.

さらに他の実施の形態では、図５に示す噛む歯ブラシ１である。上記の板バネプレート１０と硬質金属板１３によりブラシ台２の湾曲度を調整するものと相違し、ブラシ台２をすべてプラスチックス２２とするもので、このプラスチックス２２はエチレン酢酸ビニール樹脂（ＥＶＡ樹脂）から形成するものとする。このＥＶＡ樹脂からなるブラシ台２は７０〜８０℃の湯に浸けることで軟化するものとする。そこで、この温度とすることで軟化したブラシ台２の温度が口中に装着しうる温度に低下し、まだブラシ台２が軟化状態にあり曲げうる温度にある間に、このブラシ台２を上顎の歯並び１８にはめ込み、次いでこの状態で上下の歯でブラシ台２を噛み合わせた後、舌で上下の歯並びに沿って押しながらさらに指で上下の歯茎１８にしっかりと押しつける。以上のようにすることで、ブラシ台２を上下の歯並びの湾曲状に型合わせを行う。型合わせが終了すると、口中からブラシ台２を取り出して冷水中で冷やす。この冷却によりブラシ台２を上下の歯並びに合った形状に硬化して形状化する。このようにブラシ台２は一旦形状化されると、その形状は再び軟化温度に加熱しない限り不変に維持される。以上のようにして使用者の専用のマウスピース状の噛む歯ブラシ１を得ることができる。この場合、上記のＥＶＡ樹脂に変えて他の形状記憶樹脂を用いることもできることはいうまでもない。   In still another embodiment, the toothbrush 1 is shown in FIG. Unlike the case where the degree of curvature of the brush base 2 is adjusted by the leaf spring plate 10 and the hard metal plate 13, the brush base 2 is entirely made of plastics 22, which is made of ethylene vinyl acetate resin (EVA). Resin). The brush base 2 made of EVA resin is softened by being immersed in hot water of 70 to 80 ° C. Therefore, the temperature of the softened brush base 2 decreases to a temperature that can be worn in the mouth by setting this temperature, and while the brush base 2 is still in a softened state and can be bent, the brush base 2 is moved to the upper jaw. After fitting into the tooth arrangement 18 and then meshing the brush base 2 with the upper and lower teeth in this state, the finger is pressed firmly against the upper and lower gums 18 with the fingers while pressing along the upper and lower teeth with the tongue. By doing in the above, the brush stand 2 is mold-matched in the curved shape of the upper and lower teeth. When the mold matching is completed, the brush base 2 is taken out from the mouth and cooled in cold water. By this cooling, the brush base 2 is hardened into a shape matching the upper and lower teeth and shaped. Thus, once the brush base 2 is shaped, its shape is maintained unchanged unless it is heated again to the softening temperature. As described above, the user's exclusive mouthpiece-shaped biting toothbrush 1 can be obtained. In this case, it goes without saying that other shape memory resins can be used instead of the EVA resin.

上記の各実施の形態の噛む歯ブラシ１は、ブラシ台２のブラシ部３から歯ブラシの毛１７が歯茎１８や歯肉１９や歯周ポケット２０および歯２１の方向に向けて植毛されているので、上下の歯並び間に嵌めて、上下の歯２１の間でかみ合わせることで、ブラシ部３の毛１７が歯茎１８や歯肉１９や歯２１を摩擦し、さらに歯周ポケット２０に入り込み、これらをマッサージすると共に磨き上げることができ、歯垢なども良好にとることを可能とする。さらに、この噛む歯ブラシ１は把持具７を握って左右に動かすことで歯並び全体の歯茎１８や歯２１を磨くことができる。   In the toothbrush 1 to be chewed in each of the above embodiments, since the toothbrush bristles 17 are planted from the brush portion 3 of the brush base 2 toward the gums 18, gums 19, periodontal pockets 20, and teeth 21, The teeth 17 of the brush part 3 rub against the gums 18, gums 19, and teeth 21, and further enter the periodontal pocket 20 to massage them. It can be polished together with dental plaque and the like. Furthermore, this chewing toothbrush 1 can polish the gums 18 and teeth 21 of the entire tooth arrangement by grasping the gripping tool 7 and moving it to the left and right.

これらの噛む歯ブラシ１は、例えば把持具７にブラシ台２を振動させる電動モーターを配設することで、一層効率よく磨けるようにすることができる。さらにまた把持具７からブラシ台２の中に水路を配設し、さらにブラシ台２に噴出孔を開口し、把持具７に噴流水発生装置を配設してブラシ台２を水洗水の噴出ノズルあるいは歯磨き液の噴出ノズルとすることができる。   These biting toothbrushes 1 can be polished more efficiently by arranging, for example, an electric motor that vibrates the brush base 2 in the gripper 7. Furthermore, a water channel is arranged in the brush base 2 from the gripping tool 7, an ejection hole is further opened in the brush base 2, and a jet water generator is provided in the gripping tool 7 to eject the flush water from the brush base 2. It can be set as a nozzle or an ejection nozzle of a toothpaste.
