Description

本願発明は歯ブラシに関する。 The present invention relates to a toothbrush.

歯ブラシには従来から各種形態、構造のものがある。それらの例として、歯磨きの際の歯や歯茎への負担を減らすために、柄とブラシの間に波状の可動部Ａを設けたもの（図３）や、ブラシの前後方向中央部にブラシの先端が内側に曲がる屈曲部を備えたもの（特許文献１）などがある。 Conventional toothbrushes have various forms and structures. For example, in order to reduce the burden on teeth and gums when brushing teeth, a wavy movable part A is provided between the handle and the brush (FIG. 3), or the brush is placed in the center in the front-rear direction of the brush. There is one having a bent portion whose tip is bent inward (Patent Document 1).

特開２００２−５１８３８号公報JP 2002-51838 A

しかし、従来の発明の可動部も屈曲部も可動方向や屈曲方向が使用時に歯や歯茎に圧力のかかる方向のみであるため以下のような課題があった。
（１）歯の細部特に奥歯の奥側など磨く場合には、ブラシが奥側に当たりにくく、磨き残りができやすかった。
（２）ブラシ、可動部或いは屈曲部、柄が固定式であるため、それらの一部が摩耗或いは損傷すると部分的な交換が出来ず、歯ブラシ全体を交換しなればならず、まだ使用可能な部分（例えば、柄）が無駄になり、不経済であった。 However, the movable part and the bent part of the conventional invention have the following problems because the movable direction and the bending direction are only directions in which pressure is applied to the teeth and gums during use.
(1) When brushing the details of the teeth, especially the back side of the back teeth, it was difficult for the brush to hit the back side, and it was easy to finish the brush.
(2) Since the brush, movable part or bent part, and the handle are fixed, if a part of them is worn or damaged, it cannot be partially replaced, and the entire toothbrush must be replaced and can still be used. A part (for example, a handle) was wasted and was uneconomical.

本願発明の課題は、前記課題を解決できると同時に、磨き残りができにくく、歯及び歯茎に確実に接触するが歯及び歯茎への負担（接触圧）の少ない歯ブラシを提供することにある。 An object of the present invention is to provide a toothbrush that can solve the above-mentioned problems and is difficult to be brushed and that reliably contacts the teeth and gums, but has less burden on the teeth and gums (contact pressure).

本願発明の歯ブラシは、請求項１記載のように、柄の先にブラシを備えた歯ブラシにおいて、柄とブラシの間に柄の周方向３６０度いずれの方向にも湾曲・復元可能な弾性体を備えたものである。請求項２記載のように、前記弾性体をコイルスプリング又は線バネとすることができる。また、請求項３記載のように、ブラシと、柄と、弾性体を分離・連結可能とすることもできる。 The toothbrush of the present invention is a toothbrush having a brush at the tip of a handle as claimed in claim 1, wherein an elastic body that can be bent and restored in any direction of 360 degrees in the circumferential direction of the handle is provided between the handle and the brush. It is provided. The elastic body can be a coil spring or a wire spring. Further, as described in claim 3, the brush, the handle, and the elastic body can be separated and connected.

本願発明の歯ブラシには次のような効果がある。
（１）弾性体が柄の周方向３６０度いずれの方向にも湾曲・復元可能であるため、奥歯の奥側、歯の内側まで確実に接触でき磨き残りができにくい。
（２）歯及び歯茎に確実に接触しても、歯及び歯茎への接触圧が弱いので、歯及び歯茎が損傷しにくい。
（３）ブラシ、弾性体、柄の各部材を分離・連結可能であるため、消耗或いは損傷した部材だけを交換することができ、無駄がなく、経済的である。 The toothbrush of the present invention has the following effects.
(1) Since the elastic body can be bent and restored in any direction of 360 degrees in the circumferential direction of the handle, it is possible to surely contact the back side of the back tooth and the inside of the tooth, and it is difficult to leave a polish.
(2) Even if the teeth and gums are securely contacted, the contact pressure on the teeth and gums is weak, so that the teeth and gums are not easily damaged.
(3) Since the brush, elastic body, and handle members can be separated and connected, only worn or damaged members can be replaced, which is economical and economical.

（実施形態１）
本願発明の歯ブラシの実施形態の一例を図１及び図２に基づいて説明する。この実施形態の歯ブラシは図１に示すようにブラシ１と弾性体２と柄３を備えており、弾性体２にコイルスプリングを使用してある。前記ブラシ１や柄３の材質、形状、構造等は汎用の歯ブラシのそれらと同じものであってもよく、新規なものであってもよい。弾性体２として使用するコイルスプリングの線径、巻き数、巻き径、巻き間隔、長さ、弾性強度等は子供用、大人用といったように用途に合せて各種用意することができる。コイルスプリングは、隙間をあけて巻いたものであっても、密に巻いたものであってもよい。コイルスプリングは錆び難いステンレスのような金属製とすることができるが、樹脂製とか他の材質製とすることもできる。 (Embodiment 1)
An example of an embodiment of the toothbrush of the present invention will be described with reference to FIGS. As shown in FIG. 1, the toothbrush of this embodiment includes a brush 1, an elastic body 2, and a handle 3, and a coil spring is used for the elastic body 2. The material, shape, structure, and the like of the brush 1 and the handle 3 may be the same as those of a general-purpose toothbrush or may be new. The coil spring used as the elastic body 2 can have various wire diameters, winding numbers, winding diameters, winding intervals, lengths, elastic strengths, and the like according to applications such as for children and adults. The coil spring may be wound with a gap or may be wound tightly. The coil spring can be made of metal, such as stainless steel, which does not easily rust, but can also be made of resin or other materials.

図１のブラシ１、弾性体２、柄３は分解・連結可能としてある。図１に示したものはブラシ１の基材４の根元側を弾性体２の一端に圧入固定可能な太さのブラシ連結軸５とし、柄３の先端側を弾性体２の他端に圧入固定可能な太さの柄連結軸６にしてある。分解・連結構造はこれ以外であってもよく、例えば、ブラシ連結軸５を弾性体２の一端に被せて固定可能な太さの筒状にし、柄連結軸６を弾性体２の他端に被せて固定可能な太さの筒状にすることもできる。ブラシ１、弾性体２、柄３は分解できない固定式のものでもよい。 The brush 1, the elastic body 2, and the handle 3 in FIG. 1 can be disassembled and connected. 1 shows that the base side of the base 4 of the brush 1 is a brush connecting shaft 5 having a thickness that can be press-fitted and fixed to one end of the elastic body 2, and the tip side of the handle 3 is press-fitted to the other end of the elastic body 2. The handle connecting shaft 6 has a thickness that can be fixed. The disassembling / connecting structure may be other than this. For example, the brush connecting shaft 5 is placed on one end of the elastic body 2 to be fixed in a cylindrical shape, and the handle connecting shaft 6 is connected to the other end of the elastic body 2. It is also possible to form a cylindrical shape that can be fixed by being covered. The brush 1, the elastic body 2, and the handle 3 may be fixed types that cannot be disassembled.

前記弾性体２にはコイルスプリングを使用してあるが、それ以外のもの、例えば、図２のように細い弾力性（復元性）のある線バネを数本使用することもできる。線バネは一本でも良く、その場合、線バネを柄の中心部分に設けると使いやすい。また、弾力性（復元性）のある線バネ、ゴム、軟質樹脂製の丸棒とか丸パイプ等とすることもできる。 Although the coil spring is used for the elastic body 2, other wire springs, for example, a few wire springs having thin elasticity (restorability) as shown in FIG. 2, can be used. One wire spring may be used. In this case, it is easy to use a wire spring provided at the center of the handle. Moreover, it can also be a wire spring with elasticity (restorability), rubber, a round bar made of soft resin, a round pipe, or the like.

前記弾性体２の材質は錆にくいステンレス製が適するが、他の材質、例えば、ステンレス以外の金属、ゴム、樹脂といったものであってもよい。前記、分解・連結構造も前記以外であってもよく、例えば、ネジ込み式等であってもよい。 The material of the elastic body 2 is suitably made of stainless steel that is not easily rusted, but other materials such as metals other than stainless steel, rubber, and resin may be used. The disassembling / connecting structure may be other than the above, and may be, for example, a screwed type.
