Abstract
【課題】 通常の歯ブラシでは毛先があたりにくい歯と歯の間や歯と歯茎の境などに清掃要素をあてて、やわらかい歯垢や食べかす（付着物）をかきとることができる歯ブラシ。
【解決手段】 ブラシヘッドに固着される清掃要素であるフィンの先端部分は薄くて狭い幅のヘラなので、狭くて平行でない歯の隙間にも少ない抵抗で侵入でき、フィンの抜き差し操作で歯の側面についた付着物をかきとることができます。
前記フィンを側面からみた形状は、先端を頂点として根元を底辺とした中空部分がある略三角形で、先端部分にかかる厚みを曲げる方向の力(Ff)に対しては弾性をもって変形し力がなくなると復元するので、先端でなぞることで付着物をかきとることができます。
一方側方からかかる力(Fs)に対しては、前記フィンは変形しないで柄にかけた力を先端に伝えますので、縦長の歯間に沿って先端を操作することで、歯間の付着物がとれます。
【選択図】 図３PROBLEM TO BE SOLVED: Toothbrush which can remove a soft plaque and a bite (attachment) by applying a cleaning element between teeth and between teeth and between teeth and gums, which are difficult to touch with a normal toothbrush.
SOLUTION: Since the tip of the fin, which is a cleaning element fixed to the brush head, is a thin and narrow spatula, it can enter a gap between narrow and non-parallel teeth with little resistance. You can scrape off any deposits attached to the surface.
The shape of the fin viewed from the side is a substantially triangular shape having a hollow portion with the tip at the top and the base at the bottom, and the force (Ff) in the direction of bending the thickness applied to the tip portion is elastically deformed and the force disappears. Because it is restored, you can scrape off the deposits by tracing with the tip.
For the force (Fs) applied from one side, the fin does not deform and transmits the force applied to the handle to the tip. You can take.

Description
本考案は通常の歯ブラシではとりにくい歯と歯の間の面や歯と歯茎の境部分に付着している、やわらかい歯垢や食べかすをかきとる清掃要素を有する歯ブラシに関します。 The present invention relates to a toothbrush having a cleaning element that scrapes away soft plaque and food residue attached to the surface between teeth and the boundary between teeth and gums, which is difficult to remove with a normal toothbrush.
毎日歯磨きをしているのに、歯周病を患っている人が多くいます。私もその一人です。いろいろな刷毛形状の歯ブラシや補助清掃具、電動歯ブラシや超音波歯ブラシなどを試みましたが歯周病から開放されず、歯周病患者として満足できる歯ブラシを考えました。
やわらかい歯垢や食べかすを歯や歯茎に付着したままでいますと、歯周病菌など有害な細菌がそこで繁殖して歯周病などになりやすく、またやわらかい歯垢はそのまま放置されますとかたい歯石に変わり、強固に歯に付着して素人ではとれなくなりますので、毎日の歯磨きでやわらかいうちにとることが重要です。
歯垢や食べかすを確実に取れば、歯周病菌などの居場所がなくなり歯周病から開放されるという因果関係は明確ですが、歯のすべての部分に毛先をあてることができる歯ブラシがないため、歯磨きだけでは歯垢が取りきれません。また毛先をあてないで歯垢をとるために、高速振動による水流や水中のキャビテーションを利用する電動歯ブラシや超音波歯ブラシの利用は、口の中で歯垢除去効果のある条件を作り出すことが大変困難です。
Many people have periodontal disease even though they brush their teeth every day. I am also one of them. I tried various brush-shaped toothbrushes, auxiliary cleaning tools, electric toothbrushes and ultrasonic toothbrushes, but I thought of a toothbrush that was not released from periodontal disease and that I could satisfy as a patient with periodontal disease.
If soft plaque or food residue is left attached to the teeth or gums, harmful bacteria such as periodontal bacteria will proliferate there and tend to become periodontal disease, and soft plaque will be left as it is It is important to take it softly with daily tooth brushing, as it will stick firmly to the teeth and cannot be removed by an amateur.
The causal relationship is clear that if you remove plaque and food, you will be free from periodontal disease, and there is no toothbrush that can apply the tip to all parts of your teeth. Toothpaste is not enough to remove plaque. In addition, the use of electric toothbrushes and ultrasonic toothbrushes that utilize water flow by high-speed vibration and underwater cavitation to create plaque without applying hair tips can create conditions that can remove plaque in the mouth. It is very difficult.
刷毛形状をいろいろ工夫した歯ブラシがありますが、奥歯と前歯でも歯の形状はまったく違い、すべての人のすべての歯に適合する刷毛形状を作り出すことは不可能です。また歯と歯茎の境のラインは歯並びの良い人でも直線ではないので、直線列の刷毛や歯ブラシの一端で、歯垢や食べかすなどの直線でない部分の付着物を取るには無理があります。
刷毛の一本一本を先端が細いテーパ形状にして、狭い歯間に入りやすくした歯ブラシがありますが、通常刷毛束になっているので一本の刷毛だけで歯の隙間を磨くことはなく、一つの隙間に多くの先端を集中させると、先端は細くても刷毛同士が押し合って入れなくなってしまいます。仮に一本だけ入ったとしても、刷毛の断面と同じ形状の隙間でなければあたらない部分があり、一本の刷毛で歯の側面を磨く困難さは想像できると思います。
通常の歯ブラシで毛先があたらない部分に補助清掃具は有効ですが、隙間に適合しない補助清掃具はかえって有害な場合もあります。
歯間ブラシは歯茎近くの隙間に直接側面から挿入できますが、通常は歯茎側よりも狭い隙間になるかみ合わせ近くの歯の側面まで磨くには困難さがあります。歯間ブラシの芯径より狭い歯の隙間に入れるには構造上無理があり、すべての歯の隙間に適合するように、サイズの異なった歯間ブラシを準備するのは大変なことです。
デンタルフロスは通常狭い隙間の歯のかみ合わせ側から歯と歯の間に入れることはできますが、歯茎に近い部分の隙間は通常広くなっており、刷毛一本を歯間に入れても磨くのが困難なように、直線のフロスで歯の曲面を磨くのは難しいものです。
There are toothbrushes with various brush shapes, but the tooth shape is completely different between the back and front teeth, and it is impossible to create a brush shape that fits all teeth of all people. In addition, the line between the teeth and gums is not straight even for people with good teeth, so it is difficult to remove the adhesion of non-straight parts such as plaque and freckle at one end of a brush or toothbrush in a straight line.
There are toothbrushes that make each brush a tapered shape with a narrow tip, making it easy to fit between narrow teeth, but since it is usually a bundle of brushes, there is no brushing of the tooth gap with just one brush, If many tips are concentrated in one gap, even if the tips are thin, the brushes will press against each other and will not be able to enter. Even if only one is included, there is a part that must be a gap that has the same shape as the cross section of the brush, and you can imagine the difficulty of brushing the side of the tooth with a single brush.
Auxiliary cleaning tools are effective for areas where normal toothbrushes do not touch the tips, but auxiliary cleaning tools that do not fit in the gaps may be harmful.
The interdental brush can be inserted directly into the gap near the gums from the side, but it is usually difficult to polish to the side of the tooth near the mesh that is narrower than the gum side. It is structurally impossible to fit in the gap between teeth that is narrower than the core diameter of the interdental brush, and it is difficult to prepare interdental brushes of different sizes to fit all the interdental gaps.
Dental floss can usually be inserted between the teeth of the narrow gap teeth, but the gap near the gums is usually wide, and it can be polished even if a brush is inserted between the teeth. It is difficult to polish the curved surface of teeth with a straight floss.
過去より、刷毛形状を多くの人の歯に合うように工夫したり、磨く場所を限定した特殊形状歯ブラシの特許が数多くありますが、歯磨きをしているのに歯周病で悩んでいる人が多いことを考えると、なお解決すべき問題点があるようです。
以下、調査した本考案に関連する特許文献について、本考案との違いとなお残る問題点とを説明します。
There have been many patents of special shape toothbrushes that have been devised to fit the teeth of many people and limited places to brush, but those who are suffering from periodontal disease even though they are brushing their teeth Considering many things, it seems that there are still problems to be solved.
In the following, the patent documents related to the present invention investigated will be explained about the differences from the present invention and the remaining problems.
[特許文献１]（[図５]斜視図参照）は、歯の隙間に毛先を入れて食べ滓（かす）を除去するための歯ブラシで、幅(t) の狭い刷毛束の先がＵ字形に整えられてほぼ歯の巾に合わせて数列配置されています。Ｕ字ではなく、二列ブラシが歯の巾に合わせて数列配置されている[U.S.Pat. 1,929,530]もあります。
幅(t) の狭いＵ字形の刷毛束両端の毛先部分は、形状的に歯と歯の隙間に入りやすいのですが、文中の作用で示されている毛の反発力で奥にある食べ滓（かす）を押し出すためには、直角に弾性変形しても復元できるフィラメント（細線）材料が必要です。
本考案の清掃要素は刷毛束ではなくフィンです。また先端部分は一列の刷毛束であっても根元部分は一体化した板状でなければ側方からの力に耐えられません。参照文献の複数の刷毛束のうちの一つを取り出した正面形状は本考案の請求項２と近いものですが、構造は大きく異なり性能も異なります。
本発明のフィンは、薄板のたわみ弾性と三角形状による位置の安定性を利用して、厚みを曲げようとする力(Ff)対して大きく弾性変形し、力がなくなれば元の三角形に戻ります。一方側方からの力(Fs)に対しては、板状のフィンは変形しないで力を伝えますので、歯間に詰まった食べかすなどを、フィンを側方に力がかかるよう操作して押し出すことができます。
[特許文献２]は毛束と基部のカップを加熱溶融一体化し、本体のホルダに圧入掛け止めする毛束固定の工法ですが、中で示されている形状のワンタフト（一束）ブラシとか二束のブラシの出願は、替えブラシ用などにも多くあります。歯にあたる先端が点ですので、鉛筆でなぞる要領でどこでも磨けるように思えますが、刷毛束の根元は太い略円錐形状になっているので、狭い歯間や奥歯の奥には適しません。
本考案の清掃要素は先端部分が円錐形状ではなく、薄くて狭い幅のヘラ状なので、ワンタフトブラシの円錐型刷毛束や、直角の柄を付けた歯間ブラシとは形状が異なります。
[特許文献３]は、刷毛束寸法を限定した一列ブラシです。用途も歯周ポケットに限定して開発されており、ブラシヘッド上の幅(wr)１.０〜１.５mm、長さ(w) ２〜４mmの面積に細線の刷毛が密集しています。さらに前記限定をはずして幅を狭く長さを長くした場合、狭い隙間には入りやすくなりますが強度も弱くなり、細線の刷毛は変形しやすく変形すると復元しにくくなります。
使う立場からいえば、狭い部分に入りやすく、変形しにくく、復元しやすく、さらに使う場所を限定されずにいろいろな部分の歯垢をとることができる歯ブラシが希望です。
本考案の清掃要素は、刷毛束ではなくフィンです。[図１側面図]の先端部分幅寸法(t) は０.１mm以下、根元部分幅寸法(wr)は２.０mm以上となります。[図１正面図]の先端部分長さ寸法(ws)は２mm以下、根元部分長さ寸法(w) は５mm以上になります。先端部と根元が同一寸法ではなく、フィンを側面からみた略三角形形状は変形しにくく、また変形しても復元しやすい形状です。
[特許文献４]（[図６]斜視図参照）は、植毛基体を基点にループを形成するブリッスル（刷毛）を有している歯ブラシで、歯肉を傷つけたり痛めたりすることのない歯ブラシを提供しています。U.S.Pat. 6,260,229、U.S.Pat. 2,599,191、などもループ形状の刷毛を有しています。
本考案の清掃要素はフィンで刷毛（ブリッスル）ではありません。フィン先端には曲率がないのでループ形状でもありません。先端に曲率があると狭い隙間に侵入させるという課題が解決できません。本発明の[図１側面図]に示されている略三角形は、先端から根元に向かって徐々に広がる人が足を開いて立っている形状で、先端に曲率はありません。
[図５正面図]に示されている側方からの外力[Fs]に対して、ループ形状の刷毛をループ面に直角方向に並べても、力を一本で受けるか多数本で受けるかの違いですが、本考案では根元部分は一体化した板状ですので、板は厚みと直角の方向には容易に変形しません。
[特許文献５]（[図７]フィン図参照）は、ブラシヘッド上にブリッスル（刷毛）と接触した歯と歯の間に割り込むことができる接触破断フィンを持った歯ブラシで、通常は接触していて磨けない歯と歯の接触面も磨くことができる歯ブラシです。
接触破断フィンは、接触した歯と歯の間に入り込むためにはできるだけ薄く適当なテーパを有することが必要な一方で、狭い歯間に割り込ませる大きな力がかかってもフィン先端が変形しない強度を得るためには、ある厚さが必要という矛盾に遭遇します。
使う立場からいえば、隙間がない部分へ強引に押し込むよりは、隙間の量や形状に合わせて自然に入り込む方が不安感が少ないので、本考案のフィンには[特許文献５]で要求されている曲げ係数やテーパ夾角の制限はありません。隙間侵入フィンとして小さな力で狭い隙間に侵入できます。
本考案では刷毛（ブリッスル）は構成要素ではなく、フィンが清掃要素です。歯と歯の狭い隙間に侵入しますので、フィン先端部分の厚み(t) が薄いことは絶対的条件ですが、接触している歯と歯の間に先端を割り入れるための最適テーパ角や、大きな力がかかっても変形しない強度や、表面硬度、高強度樹脂材料の選定などは必要としていません。
歯と歯の接触を破断して割り込んでも、隣りあった歯の側面は平行ではないので、変形しないフィンは一部分にしかあたらず、抜き差し運動で歯の側面すべてにあたるわけではありません。本考案では、中空部分がある略三角形のフィンが歯と歯の隙間形状にあわせて変形しながら侵入しますので、抜き差し運動で歯の側面の多くの部分に接触でき、歯の側面の付着物を取ることができます。フィン先端部分のテーパになった幅は有効です。
また、別のフィン構造は、ブラシヘッド上に両端を固定した弓形の薄いリボン状ループ部分と、前記ループのほぼ中央から歯ブラシ本体とは反対方向にある歯間接触破断のためのスプリットブレードとで構成されております。中空部分は歯間に入らない構造です。
本考案では単に前記ループ部分がないだけではなく、歯間の大きさによってはフィンの根元まで入る可能性もあり、先端から根元に向かって徐々に広がる人が足を開いて立っている形状のため前記ブレード部分とループ部分が区別できない構造で、フィン先端部分が歯間接触部分を破断する力に耐えることを求めてもいません。
[特許文献６]（[図８]実施例参照）は、間隔を置いて長手方向に直角な二枚の長方形の弾力があり、変形しやすいシートや、二列のブリッスルでできた歯の側面磨き装置です。さらに多くの刷毛束列でできた歯ブラシに、U.S.Pat. 1,929,530、U.S.Pat. 4,128,910、などさまざまな形状がありますが、隣り合った歯の狭い隙間、広い隙間、いろいろな形状の隙間に一本の歯ブラシで適合させるのには、無理があります。
本考案のフィンは、先端と根元が平行なシートや刷毛束列とは側面からみた形状が違います。根元は平行な二枚のシートでも先端が一つになった略三角形形状をしたフィンで、平行でない歯と歯の狭い隙間や歯茎の境近くのデルタ形状の隙間にも侵入できます。さらに正面からみた形状も長方形ではなく先端から根元に向かって幅広の略三角形で、シートや一列の刷毛束の一端をブラシヘッドに固着した形状とは異なります。
[特許文献７]（[図９]実施例参照）は、一端がくっつき他端が離れたＶ字形状をした、弾力があり細長い牙形状の歯科装置で、歯周組織を傷つけないようにエッジ部などは工夫されています。
爪楊枝に代わる使い方になりますので、奥歯には前記歯科装置に直角の柄がないと使いにくい清掃要素です。牙形状で、二枚の均一でない幅の薄板の一端は全長でくっついていますので、離れた他端側の開き量はサイズと開き角度で決まり、前記開き量より狭くて、歯と歯の間に適度な隙間がある部分に有効です。
本考案の請求項３では部分的に牙形状部分ができます。前記牙形状部分はブラシヘッドに直角に付きますので奥歯にも使えますし、歯と歯の隙間がＶ字の開き量より広い場合でも歯の側面を一つずつ、Ｖ字の開いたエッジで容易に磨くことができますし、先端は薄いヘラ状なので狭い歯間にも容易に侵入できます。
[特許文献８]（[図１０]実施例参照）は、芯にメタルプレートがある鋸歯状ラバープロジェクションを、ヘッド外周に配置したマッサージ装置です。鋸歯状という外観に本考案と類似点がありますが、求める機能と目的が違うために多くの点で異なります。
本考案の請求項２のフィンは正面からみると鋸歯形状です。しかし芯にメタルプレートはありませんし、連続形状ではありません。また先端部分は狭い隙間に入れるヘラ状で、マッサージ用のプロジェクションではありません。さらに本考案は材質がラバーでは機能が落ちますし、側面からみた形状は目的の違いから全く異なります。
本考案のフィンには、ヘラの厚みを曲げる力(Ff)に対しては弾力と復元力が、直角方向の力(Fs)に対しては、変形しないで力を伝える機能が求められます。一方マッサージが目的の[特許文献８]ではかけた力をそのまま伝えず変形するラバーが望ましくなります。
マッサージが目的の場合には狭い隙間に入る先端は必要ありませんので、薄いヘラ状のフィンは不要で、先端は柔らかく丸まっていればよく、マッサージのために大きな力で押しつけてもそのまま先端部分に力を伝えず材料が変形したほうが良いので、機能と目的の違いから本考案とは正面からみた鋸歯形状以外は異なります。
[Patent Document 1] (refer to [FIG. 5] perspective view) is a toothbrush that removes eating waste by putting a hair tip into a gap between teeth, and the tip of a brush bundle having a narrow width (t) is U It is arranged in a letter shape, and several rows are arranged according to the width of the teeth. There is also [USPat. 1,929,530] in which two rows of brushes are arranged in line with the width of the teeth instead of being U-shaped.
The tips of the ends of the U-shaped brush bundle with a narrow width (t) tend to enter the gap between the teeth in terms of shape. In order to extrude cocoons, filament (thin wire) material that can be restored even if elastically deformed at right angles is required.
The cleaning element of the present invention is not a brush bundle but a fin. Even if the tip part is a single line of brush bundles, the root part cannot withstand the force from the side unless it is an integrated plate. The front shape of one of the multiple brush bundles in the reference is similar to claim 2 of the present invention, but the structure is greatly different and the performance is also different.
The fins of the present invention use the flexural elasticity of the thin plate and the stability of the position due to the triangular shape to greatly deform the force (Ff) to bend the thickness and return to the original triangle when the force disappears . For the force (Fs) from one side, the plate-like fins transmit the force without deformation, so push out the clogged clogs between teeth so that the force is applied to the side. can do.
[Patent Document 2] is a method of fixing a hair bundle in which the hair bundle and the base cup are heated and melted together and press-fitted into the holder of the main body, but the one-tuft brush (two bundles) of the shape shown in There are many applications for bunch brushes for replacement brushes. The tip that hits the tooth is a point, so it seems that you can brush it anywhere with a pencil. However, the root of the brush bundle has a thick, generally conical shape, so it is not suitable for narrow spaces between teeth or the back of the back teeth.
The cleaning element of the present invention has a thin and narrow spatula shape instead of a conical tip, so the shape is different from a one-tuft brush conical brush bundle or an interdental brush with a right-angled handle.
[Patent Document 3] is a single-line brush with limited brush bundle dimensions. The application has been developed only for periodontal pockets, and fine brushes are concentrated in the area of width (wr) 1.0-1.5mm and length (w) 2-4mm on the brush head. Furthermore, when the above limitation is removed and the width is narrowed and the length is lengthened, it will be easy to enter the narrow gap, but the strength will also be weakened, and the thin brush will be easily deformed and will be difficult to restore.
From the standpoint of use, we would like a toothbrush that can easily enter into a narrow part, is difficult to deform, is easy to restore, and can take plaques in various parts without being limited to where it is used.
The cleaning element of the present invention is not a brush bundle but a fin. The tip width (t) in [Figure 1 Side View] is 0.1 mm or less, and the root width (wr) is 2.0 mm or more. In [Fig. 1 front view], the tip length (ws) is 2 mm or less, and the root length (w) is 5 mm or more. The tip and root are not the same size, and the approximate triangular shape of the fin viewed from the side is difficult to deform and can be easily restored even when deformed.
[Patent Document 4] (see [FIG. 6] perspective view) is a toothbrush having a bristle (brush) that forms a loop with a flocked base as a base, and provides a toothbrush that does not damage or hurt the gums doing. USPat. 6,260,229, USPat. 2,599,191, etc. also have loop-shaped brushes.
The cleaning element of the present invention is a fin, not a brush. Since there is no curvature at the tip of the fin, it is not a loop shape. If there is curvature at the tip, the problem of entering a narrow gap cannot be solved. The approximate triangle shown in [Figure 1 Side View] of the present invention is a shape in which a person who gradually spreads from the tip to the base stands with his legs open, and there is no curvature at the tip.
Whether external force [Fs] from the side shown in [Figure 5 Front View] is received by a single line or multiple lines even if loop-shaped brushes are arranged perpendicular to the loop surface. The difference is that in the present invention, the base part is an integrated plate, so the plate does not easily deform in the direction perpendicular to the thickness.
[Patent Document 5] (see [FIG. 7] fin diagram) is a toothbrush having a contact breaking fin that can be inserted between teeth that contact a bristle (brush) on the brush head, and is usually in contact with the toothbrush. It is a toothbrush that can polish the contact surface between teeth that cannot be brushed.
The contact breaking fin needs to have an appropriate taper that is as thin as possible in order to get into contact between teeth. You will encounter the contradiction that you need a certain thickness to get it.
From the standpoint of use, rather than forcibly pushing into a part where there is no gap, there is less anxiety to naturally enter the gap according to the amount and shape of the gap, so the fin of the present invention is required in [Patent Document 5]. There is no limit on the bending factor or taper angle. As a gap intrusion fin, it can enter a narrow gap with a small force.
In the present invention, the brush is not a component but a fin is a cleaning element. It is an absolute requirement that the fin tip has a small thickness (t) because it penetrates into the narrow gap between the teeth, but the optimum taper angle for inserting the tip between the contacting teeth and the tooth There is no need to select strength that does not deform even when a large force is applied, surface hardness, or high-strength resin material.
Even if the contact between the teeth is broken and interrupted, the side surfaces of the adjacent teeth are not parallel, so the fins that do not deform are only part, and not all the side surfaces of the teeth by the insertion and removal movement. In the present invention, since the triangular fin with a hollow part enters while deforming according to the shape of the gap between the teeth, it can contact many parts of the tooth side by pulling out and inserting, and the attachment on the side of the tooth Can take The tapered width of the fin tip is effective.
Another fin structure includes an arcuate thin ribbon-like loop portion fixed at both ends on the brush head, and a split blade for interdental contact fracture from the center of the loop in the opposite direction to the toothbrush body. It is composed. The hollow part does not fit between teeth.
In the present invention, not only the loop part is not included, but depending on the size of the teeth, there is a possibility of entering the base of the fin. Therefore, the blade part and the loop part are indistinguishable from each other, and the fin tip part is not required to withstand the force that breaks the interdental contact part.
[Patent Document 6] (see FIG. 8) is an example of a sheet having two rectangular resiliences that are perpendicular to the longitudinal direction at an interval and are easily deformable, and a tooth side surface made of two rows of bristles. Polishing equipment. There are various shapes of toothbrushes made of many brush bundles, such as USPat. 1,929,530, USPat. 4,128,910, etc. It is impossible to adapt.
The fins of the present invention have a different shape from the side of sheets and brush bundles with parallel tips and roots. The base is a fin with a triangular shape with two parallel sheets, with a single tip, and it can penetrate into narrow gaps between non-parallel teeth and delta-shaped gaps near the gums. Furthermore, the shape seen from the front is not a rectangle, but a broad triangle from the tip to the root, which is different from the shape in which one end of a sheet or bundle of brushes is fixed to the brush head.
[Patent Document 7] (see [FIG. 9] Example) is an elastic and elongated tooth-shaped dental device having a V-shape with one end stuck and the other end separated so as not to damage periodontal tissue. The department has been devised.
Since this is an alternative to toothpick, it is a cleaning element that is difficult to use unless the back teeth have a right-angle handle on the dental device. Since one end of two sheets of non-uniform width in the fang shape is attached to the entire length, the opening amount on the other end side is determined by the size and opening angle, which is narrower than the opening amount and between the teeth. Effective for areas with moderate gaps.
In claim 3 of the present invention, a fang-shaped part is partially formed. The fang-shaped part is attached to the brush head at a right angle so that it can be used on the back teeth. Even if the gap between the teeth is wider than the V-shaped opening, one side of each tooth is opened with an open V-shaped edge. It can be easily polished, and the tip is a thin spatula, so it can easily penetrate between narrow teeth.
[Patent Document 8] (see [Fig. 10] Example) is a massage device in which a sawtooth rubber projection with a metal plate at the core is placed on the outer periphery of the head. The saw-toothed appearance is similar to the present invention, but differs in many ways because of the different functions and purposes.
The fin of
The fin of the present invention is required to have a function to transmit elastic force and restoring force to the force (Ff) that bends the thickness of the spatula, and to transmit force without deformation to the force (Fs) in the perpendicular direction. On the other hand, in [Patent Document 8], which is intended for massage, a rubber that deforms without transmitting the applied force is desirable.
For massage purposes, there is no need for a tip that enters a narrow gap, so a thin spatula-like fin is not required, and the tip only needs to be soft and rounded. It is better that the material is deformed without telling, so it differs from the present invention except for the sawtooth shape seen from the front due to the difference in function and purpose.

歯垢や食べかすを確実に取れば、歯周病菌などの居場所がなくなり歯周病から開放されるという因果関係は明確ですが、歯や歯茎の形状は複雑な上さまざまで、通常の歯ブラシでは毛先をあてることが困難な部分が必ずあります。
本考案の歯ブラシはやわらかい歯垢や食べかすをとるために、通常の歯ブラシでは毛先があたりにくい平行でない狭い歯間の隙間（特に歯茎に近いデルタ部分）や歯と歯茎の境などにあてることができ、弾力と復元力を合わせ持ち、操作性が良く、コストが安い、という歯周病患者として希望する清掃要素の形状を課題としています。
The causal relationship between clearing plaque and food residue and eliminating periodontal disease bacteria and releasing from periodontal disease is clear, but the shapes of teeth and gums are complex and varied. There is always a part that is difficult to point.
The toothbrush of the present invention can be applied to narrow gaps between non-parallel teeth (especially the delta close to the gums) and the boundary between teeth and gums, which is difficult to touch with the tip of a normal toothbrush, in order to take soft plaque and food. The challenge is the shape of the cleaning element desired as a patient with periodontal disease, which has both elasticity and resilience, good operability, and low cost.
通常の歯ブラシでは毛先があたりにくい歯と歯の隙間や歯と歯茎の境などに清掃要素をあてるために、本考案の清掃要素には下記課題が与えられます。
1.) 清掃要素の先端部分は薄く(t) て、歯垢や食べかすが溜まりやすい歯と歯の間の狭い隙間（特に歯茎に近いデルタ部分や平行でない歯と歯の隙間）に少ない抵抗で侵入でき、広い隙間でも、清掃要素の抜き差し運動で歯の側面が清掃できること
2.) 清掃要素の先端部分は点ではなく狭くても幅(ws)があり、歯の表面や歯と歯茎の境に付着したやわらかい歯垢や食べかすをある幅でかきとることができる弾力があること
3.) 清掃要素は、[図１側面図]に示される厚みを曲げようとする先端への力(Ff)に対しては、弾性変形して力が大きいほど大きく変位し、力がなくなれば復元しやすいこと
4.) 清掃要素は、[図１正面図]に示されるように、先端へ側方からかかる力(Fs)に対しては変形しにくく、柄にかけた力をブラシヘッドを通して清掃要素先端部分に伝えることができ、歯間の縦長い隙間に沿って清掃要素を操作することができること
In order to apply cleaning elements to the gap between teeth and teeth and the boundary between teeth and gums, which are difficult to hit with normal toothbrushes, the cleaning elements of the present invention have the following issues.
1.) The tip of the cleaning element is thin (t) and has little resistance to narrow gaps between teeth that tend to accumulate plaque and food residue (especially the delta near the gums and gaps between teeth that are not parallel). Intrusion is possible, and even with a wide gap, the tooth side can be cleaned by inserting and removing the cleaning element.
2.) Even if the tip of the cleaning element is narrow, not narrow, it has a width (ws), and it has the elasticity to scrape soft plaque and food residue adhering to the tooth surface and the boundary between the teeth and gums with a certain width. There is
3.) With respect to the force to the tip (Ff) that tries to bend the thickness shown in [Fig. Easy to restore
4.) As shown in [Figure 1 Front view], the cleaning element is not easily deformed by the force (Fs) applied to the tip from the side, and the force applied to the handle is applied to the tip of the cleaning element through the brush head. Can communicate and be able to operate the cleaning element along the longitudinal gap between teeth
本考案は、通常の歯ブラシでは毛先をあてにくい歯間などに清掃要素をあてるために、根元を固定し先端を開放した通常の刷毛束ではなくて、たわみ弾性のある薄板を加工したフィンを清掃要素にしています。
本考案の請求項１では、[図１]で示されるように歯や歯茎と接触して機能するフィンの先端部分は厚み(t) が薄く狭い幅(ws)のヘラ状になっており、[図１側面図]のように前記先端を頂点として二股に分かれ、根元(wr)を底辺とする略三角形になっています。
前記ヘラ状の先端部分は、歯と歯の間の狭い隙間に容易に入ることができ、中空部分のある略三角形形状は、先端厚みを曲げる力(Ff)に対しては弾力をもってたわみ、力がとれると復元する形状で、弾力と復元力があります。
本考案の請求項２では、[図２]で示されるようにフィンの先端部分に狭い幅(ws)のヘラ状の清掃要素が二つあり、前記幅は先端から根元へ向かって徐々に広がり根元(w) に至るまでに一体となる二つの略三角形ができ、[図１正面図]のようにフィンの先端から根元に向かって略Ｖ字切込みがある鋸歯状です。
前記二つの先端部分は先端厚みを曲げる力(Ff)に対しては独立に変形し、側方からかかる力(Fs)に対しては変形しないので、柄(HND) から清掃要素先端を操作しやすくなります。
本考案の請求項３では、[図３]で示されるように前記略Ｖ字切込みがある高さの部分で外側を短く内側を長く先端を溶着(WLD) しているので、両外側の方がＶ字切込み部分より高い位置から二股に分かれ、部分的に牙形状になります。先端厚みを曲げる力(Ff)に対しては、溶着距離が長い方がフィンの曲げ強度は増強されます。
前記内側が溶着され外側が開放されている位置関係の先端部分をブラシヘッドに平行に切断したフィンの断面形状は、[図３の部分断面図]でおわかりのように、両外側が開放端の略Ｖ字形状になっています。
この形状は歯と歯の間が狭いときは開放端側が狭くなって隣り合った歯の両側面に弾力をもってあたり、歯茎に近い歯間のさまざまなデルタ形状にも適合できます。歯と歯の間が広い部分にはさらに深く挿入することで、隣り合った歯の両側面に開放端をあてることができますので、歯間への抜き差し運動で前記歯の両側面を清掃することができます。
In the present invention, in order to apply a cleaning element between teeth where it is difficult to apply the tip of a hair with a normal toothbrush, a fin with a flexible elastic thin plate is used instead of a normal brush bundle with the root fixed and the tip open. It is a cleaning element.
In claim 1 of the present invention, as shown in FIG. 1, the tip of the fin that functions in contact with the teeth and gums is a spatula with a small thickness (t) and a narrow width (ws). As shown in [Figure 1 Side view], it is divided into two forks with the tip at the top, and it has a substantially triangular shape with the base (wr) at the bottom.
The spatula-shaped tip portion can easily enter a narrow gap between teeth, and the substantially triangular shape with a hollow portion flexes elastically with respect to the force bending the tip thickness (Ff), and the force A shape that restores when it is removed, and has elasticity and resilience.
According to
The two tip portions are deformed independently with respect to the force (Ff) bending the tip thickness and are not deformed with respect to the force (Fs) applied from the side, so the tip of the cleaning element is operated from the handle (HND). It will be easier.
In claim 3 of the present invention, as shown in FIG. 3, the outer portion is short and the tip is welded (WLD) at the height portion where the substantially V-shaped cut is present. Is divided into two forks from a position higher than the V-shaped incision part, and it becomes partly fang-shaped. For the force to bend the tip thickness (Ff), the longer the welding distance, the stronger the bending strength of the fin.
As shown in [Partial cross-sectional view of FIG. 3], the cross-sectional shape of the fin obtained by cutting the front end portion of the positional relationship in which the inner side is welded and the outer side is open is parallel to the brush head. The abbreviation V-shaped.
When the gap between teeth is narrow, this shape is narrow on the open end and elastically hits both sides of adjacent teeth, so it can be adapted to various delta shapes between teeth close to the gums. By inserting deeper into the wide part between the teeth, the open ends can be applied to both sides of adjacent teeth, so both sides of the teeth are cleaned by inserting and removing between the teeth. can do.
さらに[図１]〜[図４]をみながら、与えられた課題を解決する手段を説明します。
1.) 本考案の清掃要素であるブラシヘッドに固着されるフィンの先端部分は、[図１]に示されるように薄く(t) て狭い幅(ws)のヘラ状になっており、薄板二枚が先端部分で一体化されて歯と歯の間の狭い隙間にも少ない抵抗で入る薄さになっていますので、先端部分が狭い隙間に直角にあたらなくても、変形して隙間に沿って少ない抵抗で侵入できます。
さらにフィンの最先端部分が略三角形形状のヘラになっており、ヘラ表面の摩擦係数が小さい方が侵入しやすいのはいうまでもありません。
また[図１側面図]の二股に分かれている内側部分は中空ですので、歯と歯の隙間が平行でない例えばデルタ形状でも歯と歯の隙間を押し広げることなく、フィンの方が隙間にならって少ない抵抗で侵入できます。また中空部分は根元側(wr)が広い略三角形ですので、広い隙間の歯間でも適当な深さを差し込むことで隣り合った歯の両側面に清掃要素を適合させることができます。
さらに[図３]では清掃要素の断面図も略Ｖ字形状になっており、部分断面図に示されるようにＶ字の先端は固着加工によって二枚の薄板をあわせた厚さよりさらに薄くなって、さまざまなデルタ形状に対してより適合しやすくなるとともに、固着部分の面積を増やすことで、薄板をより変形しにくくしています。
略三角形や略Ｖ字形など三角を基本にした本考案のフィン形状は、歯と歯の隙間の複雑な三次元形状に適合させることができ、歯と歯の隙間に応じた適当な長さを抜き差し運動することで隣り合った歯の側面を清掃することができます。
2.) 本考案の請求項２に記載の清掃要素であるフィンの先端部分は、[図２]に示されるようなヘラ状で狭い幅(ws)がありますので、鉛筆の先端のような点とは違って、ある幅(ws)で歯と歯茎の境などに付着したやわらかい歯垢や食べかすをかきとることができます。
また[図２]に示されるように二つの薄く(t) て狭い幅(ws)があるヘラは、両端に偏ってありますので、歯並びの上下・左右・裏表などの清掃する場所に合わせて使いやすい方を選択でき、歯茎がえぐれた曲線部分にも鏡を見ながら先端を正確にあててなぞるだけで、付着した歯垢や食べかすをとり除くことができます。
歯や歯茎に直接あたるフィンの先端部分は、面積が小さいため薄くても変形させるのに大きな力が必要です。直角断面が略三角形になればなおさらです。後述しているフィンの略三角形状がもつ弾力と力をあわせて、歯と歯茎の境をフィンの先端でなぞっていくと、とれにくい部分に付着しているやわらかい歯垢や食べかすをかきとることができます。
3.) 清掃要素であるフィンの形状は変形しにくく、変形しても復元しやすくするために、中空部分のある略三角形になっています。本考案のフィンでは、[図１側面図]に示される先端の厚みを曲げる力(Ff)に対しては弾性変形し、力がなくなると復元します。
前記中空部分のある略三角形形状は、次のような性質があります。材質は、たわませる力に対して、木のように折れず、紙のように丸まらず、またゴムのように材質自体が伸び縮みしないで元に戻る、弾力のある樹脂の薄板が望ましいものです。
ご承知のように三角形は三辺の長さが決まれば形状が決まります。二股に分かれた根元（二点）はブラシヘッドに固定されていますので、自由端である残りの一点を動かそうとする力(Ff)が働いたとき、二辺にある薄板には二点間距離を伸ばそうとする力と縮めようとする力がそれぞれ働き、材質が伸び縮みしなければたわみ変形します。
外部からの力(Ff)がなくなると、弾力でたわんだ辺が元に戻り、自由端である先端位置（一点）は三角形の頂点の位置に復帰します。
この形状による復元力の原理は、二本の細線によるブリッスルの上端を固着して三角形にして、上端に底辺と平行な力をかけた場合の変形・復元の仕方と、上端を固着しないで前記の力をかけた場合との違いを想像してみるとわかりやすいかも知れません。
4.) 一方、側方からかかる力(Fs)に対しては、厚み(t) と直角方向には変形させにくい板形状の性質が活きます。二枚の薄板の一端を固着して一つにし、根元部分はブラシヘッドに離れて固定された構造ですので、厚みと直角方向に変形させるためには二枚の板を同時に変形させる程度の力が必要になり、フィンは小さな力では変形せず力を伝えます。
この力伝達の原理は、前述の二本の細線ブリッスルの上端を固着して底辺に直角な力をかけた場合と、二枚の薄板の上端を固着して中空の三角柱形状にして前記力をかけた場合の変形のしやすさを想像してみるとわかりやすいかも知れません。
通常歯間の隙間は縦長で、しかも平行ではありません。平行でない縦長の隙間にテーパはあっても断面形状が長方形のフィンを差し込んで清掃するには、工夫が要ります。隙間の長さより極端に短い先端は一つの手段ですが、変形しやすく位置が決まりません。隙間の縦長方向には変形しないで力を伝えることができ、操作性がよくなければなりません。
本考案は三角形状が基本ですのでフィンの先端を差し込む深さで長さも変化しますし、柄(HND) にかけた歯間の隙間に沿った方向の力は、減衰しないで先端部分に伝わります。これにより課題のフィンの先端へ側方からかかる力(Fs)に対しては変形しにくく、歯間の細長い隙間内での操作性は良くなります。
Furthermore, while looking at [Figure 1]-[Figure 4], we will explain the means to solve the given problem.
1.) The tip of the fin fixed to the brush head, which is the cleaning element of the present invention, is a thin (t) spatula with a narrow width (ws) as shown in [Fig. 1]. Since the two pieces are integrated at the tip part and thin enough to enter the narrow gap between teeth with little resistance, even if the tip part is not perpendicular to the narrow gap, it will deform and become a gap. Along with less resistance.
Needless to say, the tip of the fin has a substantially triangular spatula, and the smaller the friction coefficient of the spatula surface, the easier it is to penetrate.
In addition, the inner part that is divided into two forks in [Fig. 1 Side View] is hollow, so even if the gap between the teeth is not parallel, for example, in the delta shape, the fins become gaps without expanding the gap between the teeth. Can penetrate with little resistance. In addition, the hollow part is an approximately triangular shape with a wide root side (wr), so it is possible to fit the cleaning elements on both sides of adjacent teeth by inserting an appropriate depth between teeth in a wide gap.
Further, in FIG. 3, the sectional view of the cleaning element is also substantially V-shaped, and as shown in the partial sectional view, the tip of the V-shape is made thinner than the combined thickness of the two thin plates by the adhering process. This makes it easier to adapt to various delta shapes and increases the area of the fixed part, making the thin plate more difficult to deform.
The fin shape of the present invention based on a triangle such as a substantially triangle or a substantially V shape can be adapted to a complicated three-dimensional shape of a tooth-to-tooth gap and has an appropriate length according to the tooth-to-tooth gap. The side surfaces of adjacent teeth can be cleaned by inserting and removing.
2.) The tip of the fin, which is the cleaning element according to
Also, as shown in [Fig.2], two thin (t) and narrow width (ws) spatulas are biased at both ends. You can select the easy one, and you can remove the adhering plaque and grime by simply tracing the tip of the curved part of the gums while looking in the mirror.
The tip of the fin, which directly hits the teeth and gums, requires a large force to deform even if it is thin because of its small area. This is even more so if the right-angled section is roughly triangular. By combining the elasticity and force of the fin shape, which will be described later, and tracing the boundary between the teeth and gums with the tip of the fin, you will scrape the soft plaque and edible material adhering to the parts that are difficult to remove. I can.
3.) The shape of the fin, which is a cleaning element, is difficult to deform, and it has a roughly triangular shape with a hollow part to make it easier to restore even if deformed. The fin of the present invention elastically deforms against the force (Ff) that bends the thickness of the tip shown in [Figure 1 Side view], and restores when the force disappears.
The substantially triangular shape with the hollow part has the following properties. The material should be a thin resin plate that does not fold like wood, does not curl like paper, and does not stretch or shrink like rubber, but returns to its original shape. is.
As you know, the shape of a triangle is determined if the length of three sides is determined. Since the root (two points) divided into two branches is fixed to the brush head, when the force (Ff) to move the remaining one point that is the free end is applied, the thin plate on the two sides The force that tries to extend the distance and the force that tries to shrink each work, and if the material does not stretch, it will bend and deform.
When the external force (Ff) disappears, the side bent by elasticity returns to its original position, and the tip position (one point), which is the free end, returns to the position of the vertex of the triangle.
The principle of the restoring force by this shape is that the upper end of the bristle by two thin wires is fixed into a triangle, and the deformation / restoration method when applying a force parallel to the base to the upper end, and the upper end is not fixed It may be easy to understand if you imagine the difference from the case of applying the power of.
4.) On the other hand, for the force (Fs) applied from the side, the plate-shaped property that is difficult to deform in the direction perpendicular to the thickness (t) is active. Since the two thin plates are fixed to one end and the root is fixed to the brush head, the force is sufficient to deform the two plates at the same time in order to deform in a direction perpendicular to the thickness. Is necessary, and the fin transmits the force without being deformed with a small force.
This principle of force transmission is based on the case where the upper ends of the two thin wire bridges are fixed and a force perpendicular to the bottom is applied, and the upper ends of the two thin plates are fixed to form a hollow triangular prism. If you imagine the ease of deformation when applied, it may be easy to understand.
The gap between teeth is usually vertically long and not parallel. Even if there is a taper in a vertically long gap that is not parallel, it is necessary to devise in order to insert a fin with a rectangular cross-sectional shape and clean it. A tip that is extremely shorter than the length of the gap is one means, but it is easily deformed and its position is not determined. It must be able to transmit force without being deformed in the longitudinal direction of the gap, and it must have good operability.
Since the basic shape of the present invention is triangular, the length also changes with the depth at which the tip of the fin is inserted, and the force along the gap between the teeth on the handle (HND) is transmitted to the tip without attenuation. . This makes it difficult to deform against the force (Fs) applied from the side to the tip of the problem fin and improves operability within the narrow gap between the teeth.
本考案のフィン形状による課題への効果について説明します。
1.) 本考案の清掃要素であるフィンの先端部分は、薄く(t) 幅(ws)の狭いヘラ状なので、歯垢や食べかすが溜まりやすい歯と歯の間の狭い隙間に少ない抵抗で侵入できます。ワンタフト（一束）ブラシより狭い歯と歯の隙間に、より深く侵入できます。
また二股に分かれている部分の内側は中空で根元に向かって広がっていますので、中空部分がなく変形しないブレードで隣り合った歯の狭い隙間を大きな力で無理に押し開かなくても、中空部分が狭くなる変形をして隙間形状にあわせて侵入できます。
本考案の請求項２に記載のフィンの先端部分は二つのヘラなので、清掃する場所によって使いやすい方を選択できます。
本考案の請求項３に記載のフィンの先端部分は部分的に牙形状なので、歯と歯の隙間が平行でないデルタ形状（特に歯茎に近いデルタ形状部分）にも侵入しやすくし、フィンをより変形しにくくし、清掃要素の抜き差し運動で歯の側面が清掃できます。
2.) 本考案の請求項２に記載のフィンは薄くて狭い幅(ws)の二つのヘラがありますので、歯並びの上下・左右・裏表など使いやすい方のヘラを清掃する場所に合わせて選択でき、歯茎近くの清掃場所に注意深く先端をあてて、ワンタフト（一束）ブラシのように点ではなくある幅(ws)でかきとることができます。
歯や歯茎に直接あたるフィンの先端部分は、面積が小さいため薄くても変形しにくく、[図１側面図]に示される本考案の略三角形状がもつ弾力とあわせて、歯の表面や歯と歯茎の境に付着しているやわらかい歯垢や食べかすをかきとることができます。根元を固定し先端が自由な通常の細線の刷毛は変形しやすく弾力は大きくありません。
3.) 本考案のフィンの側面形状は、中空部分のある略三角形です。フィンは厚みを曲げる先端への力(Ff)に対して弾性変形し、力がなくなれば復元するという課題を、たわみ材料の薄板と形状で解決していますので、材料単体より大きな力で付着物をかきとります。
本考案の形状には、弾性変形しやすい方向としにくい方向があり、歯並びが悪くて歯が重なっている歯間に対して先端が直角にあたらなくても、変形しやすい方向で先端を侵入させることができます。
4.) 側方からかかる力(Fs)に対してフィンはゴムのように簡単には変形しないので、柄にかけた力がブラシヘッドを通して清掃要素先端に伝わり、部分的にひっかかってもかけた力が減衰しないので、ひっかかりから抜けられます。材質がゴムやバネ構造ではかけた力が減衰し、操作性が劣ります。
変形しにくい方向では操作性が大変良く、先端を挿入後歯間に沿ってフィンの側方に力がかかるように操作することで、挿入した歯間の隙間が均一でなくても、狭くなった部分に付着したやわらかい歯垢や食べかすもかきとることができます。
The effect on the problem by the fin shape of this invention is explained.
1.) The tip of the fin, which is the cleaning element of the present invention, is a thin (t) and narrow (ws) spatula shape, so it penetrates into the narrow gap between teeth, where plaque and food residue tend to accumulate. I can do it. Can penetrate deeper into the gap between teeth than a one tuft brush.
Also, the inner part of the bifurcated part is hollow and spreads toward the root, so there is no hollow part and the blade does not deform, so even if you do not forcefully open the narrow gap between adjacent teeth with a large force, the hollow part It can be deformed so that it becomes narrower and can penetrate according to the gap shape.
The tip of the fin according to
Since the tip portion of the fin according to claim 3 of the present invention is partly fang-shaped, it is easy to enter a delta shape (particularly a delta shape close to the gums) where the gap between the teeth is not parallel, It is difficult to deform, and the tooth side can be cleaned by inserting and removing the cleaning element.
2.) The fin according to
The tip of the fin, which directly hits the teeth and gums, is small and difficult to deform even if it is thin. In addition to the elasticity of the substantially triangular shape of the present invention shown in [Side view of FIG. And you can scrape soft plaque and food residue adhering to the border of the gums. A normal thin brush with a fixed root and free tip is easy to deform and does not have a great elasticity.
3.) The side shape of the fin of the present invention is a substantially triangular shape with a hollow part. The fin is elastically deformed with respect to the force to the tip (Ff) that bends the thickness, and the problem of restoring when the force disappears is solved with a thin plate and shape of the flexible material, so the deposit is larger than the material alone Scrape off.
The shape of the present invention has a direction that is easy to elastically deform, and a direction that is difficult to deform. Even if the tips are not aligned at right angles to the gap between teeth where the teeth are not aligned, the tip is allowed to enter in a direction that easily deforms. can do.
4.) Since the fins are not easily deformed like rubber like the force applied from the side (Fs), the force applied to the handle is transmitted to the tip of the cleaning element through the brush head, and the force applied even if it is partially caught. Is not attenuated, so you can get out of the hook. If the material is rubber or a spring structure, the applied force is attenuated and the operability is poor.
The operability is very good in the direction where deformation is difficult, and the tip is operated so that a force is applied to the side of the fin along the teeth after insertion, and even if the gap between the inserted teeth is not uniform, it becomes narrow. You can also scrape soft plaque and food residue adhering to the affected area.
通常の清掃要素の先端を開放した歯ブラシでは、使っている間に毛先が開きます。根元を固定した複数の刷毛の先端を一つに固着すれば、毛先は開きにくくなります。本考案は刷毛束ではなく薄板のフィンですが、先端を一つに固着していますので先端が開きにくい効果は同じです。
爽快感を求める方には、歯みがきペーストの併用が効果的です。先端部分のヘラにごく少量の歯みがきペーストをつけて歯と歯茎の境を鏡を見ながらなぞるだけで爽快感が得られます。口の中を泡だらけにするほど使わないので経済的です。
通常の歯ブラシのように多くの刷毛を密集させていませんので、清掃要素の掃除が楽なことも考案の効果です。
With a toothbrush with a regular cleaning element open, the tip of the bristles will open during use. If you fix the tips of multiple brushes with fixed roots together, it will be difficult to open them. Although the present invention is not a brush bundle but a thin fin, it has the same effect that the tip is difficult to open because the tip is fixed to one.
For those seeking a refreshing feeling, the use of a toothpaste paste is effective. Simply apply a small amount of toothpaste paste to the spatula at the tip and trace the boundary between the teeth and gums while looking in the mirror. It's economical because it doesn't use enough to make your mouth full of bubbles.
Since many brushes are not densely packed like ordinary toothbrushes, it is also effective to devise cleaning elements that are easy to clean.
[図３]は請求項１・２・３に示された、本考案の最良の形態の歯ブラシです。部分図になっていますが、主な構成要素は柄(HND) と一体となっているブラシヘッド(BRH) と、ブラシヘッドに固着された清掃要素である本考案のフィン(FiN2)とです。

A triangle that is bifurcated toward the root with the apex at the top. When viewed from the front, there is a substantially V-shaped cut from the tip to the root, and the root is parallel to the brush head with approximately the same width (w = 10mm) as the outside of the tip. It is fixed to.
The tip of the fin (FiN2) is separated from the brush head (BRH) by a height (h = 15mm), and the heat welding (WLD) at the height where there is a substantially V-shaped cut is approximately 2mm from the tip. The inner part is welded about 5mm from the tip and the area surrounded by the shape of the tip. The cross-sectional shape of the fin cut in the 2-5mm range from the tip in parallel to the brush head is an approximately V-shape with the open end on the outside. The dimensions shown are only examples and are not limiting.
[図４]には請求項１の一つの実施例が示されています。請求項１はブラシヘッドに固着されるフィンを側面からみた形状が中空部分のある略三角形形状になっていることが特徴で、[図４]では、フィン(FiN1)を正面からみると、ブラシヘッドの中心線上に清掃要素である薄く(t=0.1mm以下) て狭い幅(ws=1mm)のヘラが一つだけある実施例です。
[図４]の実施例と最良の形態との違いは、フィン先端部分にあるヘラの数とその位置、先端部分をブラシヘッドに平行に切断した清掃要素の断面形状が略Ｖ字形状になっていないことで、図中のその他寸法は同じです。
実施例はこれに限定されるものではなく、たとえばヘラの数は３以上でもできますし、ヘラの数は一つで幅(ws)を広くも狭くもできますし、フィン(FiN1)の中心線に沿って先端部分から深く細く熱溶着して、ブラシヘッドに平行に切断したフィン先端の断面形状が、外側を開放端にした二つの背中合わせ略Ｖ字形状にすることもできます。
フィンを側面からみた形状が先端を頂点に根元を底辺とする略三角形になっている限り、平面からみた形状はさまざまな応用が可能です。
[Fig. 4] shows an embodiment of claim 1. The first aspect of the present invention is characterized in that the shape of the fin fixed to the brush head as viewed from the side is a substantially triangular shape with a hollow portion. In FIG. 4, when the fin (FiN1) is viewed from the front, the brush In this embodiment, there is only one thin (t = 0.1mm or less) narrow spatula (ws = 1mm) spatula on the center line of the head.
The difference between the embodiment shown in FIG. 4 and the best mode is that the number and position of the spatulas at the tip of the fin and the cross-sectional shape of the cleaning element with the tip cut along the brush head are substantially V-shaped. The other dimensions in the figure are the same.
The embodiment is not limited to this. For example, the number of spats can be 3 or more, the number of spatulas can be one, the width (ws) can be wide or narrow, and the center of the fin (FiN1) The cross-sectional shape of the tip of the fin, cut deeply along the line from the tip, and cut parallel to the brush head, can be made into two back-to-back substantially V shapes with the outside open.
As long as the shape of the fin viewed from the side is an approximate triangle with the apex at the top and the base at the base, the shape viewed from the plane can be used in various ways.
[図２]には請求項２の一つの実施例が示されています。請求項２はブラシヘッドに固着されるフィンを正面からみた形状が、幅(w=10mm)の両端よりにヘラがあり、先端から根元に向かって略Ｖ字切込みがある鋸歯状で、刷毛束のＵ字形や二列ブラシと違って、少なくとも根元部分は一体化されて側方からかかる力(Fs)に対して変形しにくい形状です。
[図２]の実施例と最良の形態との違いは、先端の熱溶着(WLD) 位置と面積で、[図２]の方が広い歯間に対応できますが、強度と耐久性は劣り、図中のその他寸法は同じです。
実施例はこれに限定されるものではなく、たとえばヘラの数は二つで幅(ws)は広くも狭くもできますし、略Ｖ字切込みの高さや幅、熱溶着の面積や形状、ブラシヘッドから突き出される角度など、さまざまな応用が可能です。材料も根元部分を一体化して側方からの力に対して変形しにくく加工されていれば、細線を並べてもできます。
[Fig. 2] shows an embodiment of
The difference between the example of [Fig. 2] and the best mode is the position and area of the thermal welding (WLD) at the tip. [Fig. 2] can cope with wider teeth, but the strength and durability are inferior. The other dimensions in the figure are the same.
The embodiment is not limited to this. For example, the number of spatulas is two and the width (ws) can be wide or narrow. The height and width of the V-cut, the area and shape of heat welding, the brush Various applications such as the angle protruding from the head are possible. If the material is processed so that the root part is integrated and hardly deformed by the force from the side, fine lines can be arranged.
図はありませんが請求項１〜３に記載のフィンが構成要素に含まれていれば、組み合わせて、また従来の清掃要素も組み合わせた歯ブラシをつくることができます。
例えば、[図２]のフィンはブラシヘッド上先端の位置で歯間と歯と歯茎の境用に、[図４]のフィン二つを柄の長手方向に向きを変えてブラシヘッドの両側に配置して歯周ポケット用に、さらに刷毛束の一列ブラシを前記先端位置のフィンと平行に、前記歯周ポケット用のフィンをはさんで柄側に配置して、歯の面積の広い歯面用に、などです。
これら清掃要素の組み合わせは、形状だけでなく、配置、角度、各清掃要素のサイズなど個人の歯並びの状態や好みに合わせて多数組み合わせることができます。
Although there is no figure, if the fins described in claims 1 to 3 are included in the constituent elements, it is possible to make a toothbrush that combines and combines conventional cleaning elements.
For example, the fins in [Fig. 2] are used at the tip of the brush head as a boundary between teeth and between the teeth and gums, and the two fins in [Fig. 4] are turned in the longitudinal direction of the handle on both sides of the brush head. A toothbrush with a wide tooth area is arranged for the periodontal pocket, and further, a brush in a row of brushes is arranged in parallel with the fin at the tip position and on the handle side with the fin for the periodontal pocket sandwiched between them. For, etc.
Many combinations of these cleaning elements can be combined to suit not only the shape, but also the arrangement and angle of the individual teeth, as well as the individual teeth arrangement and preferences.
図はありませんが、請求項１〜３に記載のフィンが構成要素に含まれていれば、振動や超音波振動機能を組み合わせて、先端を歯の隙間に侵入させやすい電動歯ブラシをつくることができます。狭い隙間に入りやすい清掃要素を歯や歯茎にあてるのが目的で、水流やキャビテーション現象を利用するのとは違います。 Although there is no figure, if the fins according to claims 1 to 3 are included in the constituent elements, it is possible to make an electric toothbrush that can easily penetrate the tip into the tooth gap by combining vibration and ultrasonic vibration functions. The The purpose is to apply cleaning elements that tend to enter narrow gaps to teeth and gums, which is different from using water flow or cavitation.
本考案は、従来の歯ブラシや補助清掃具では清掃要素をあてることが困難であった部分に清掃要素をあてることができ、弾力と復元力を合わせ持ってやわらかい歯垢や食べかすをかきとることができ、操作性が良く、コストが安い、という歯周病患者として希望する課題を解決できる清掃要素の形状を考えましたので、歯磨きをしていても歯周病から開放されずに困っている方々に利用していただけるものと思います。
The present invention can apply a cleaning element to a part where it was difficult to apply a cleaning element with a conventional toothbrush or an auxiliary cleaning tool, and it can scrape soft plaque and food residue with a combination of elasticity and resilience. I thought about the shape of the cleaning element that can solve the problem that I want as a periodontal disease patient that can be done, good operability and low cost, so even if I brush my teeth I am in trouble without being released from periodontal disease I think that you can use it.
