【従来の技術】
この種の吸盤としては一般に緩やかな漏斗状に形成された吸着部の外面中央部に、吊持用貫通孔を貫設した突起を形成して構成し、この突起の吊持用貫通孔に支持具（吊持具）の基端部を挿通して枢支するようにしてある（例えば、特許文献１参照）。

【発明が解決しようとする課題】
上記従来の吸盤では、吊持用貫通孔に支持具の基端部を挿通する組み付けの作業性を向上させようとすると、吊持用貫通孔と支持具の基端部との挿通を緩くすることが考えられるが、こうした場合、挿通が楽になる反面、吊持用貫通孔に挿入された支持具の基端部の支持力が弱くなり、回転しやすくなったり、はずれ易くなるという相反する問題があった。
本発明は上記問題点に鑑み提案されたもので、吊持用貫通孔に支持具の基端部を挿通する組み付けが楽に行なえるとともに、吊持用貫通孔に挿入された支持具の基端部を確りと保持して、はずれにくくした吸盤を提供できるようにすることを目的とするものである。
【０００５】
【課題を解決するための手段】
上記目的を達成するために本発明にかかる吸盤は、先ず、緩やかな漏斗状の吸着面を有する吸着部と、吸着部の外面中央部分に一体形成された連結用突起とを備え、連結用突起には吊持用貫通孔が形成されており、この吊持用貫孔に挿通された吊持具部分のずれ止め用キャップを連結用突起に嵌合させたことを特徴とするものである。
【０００６】
次に、本発明にかかる吸盤は、ずれ止め用キャップが連結用突起に嵌着されたときに、吊持用貫通孔を押圧して変形させるように連結用突起の収納用空間を形成したことも特徴の一つである。
【０００７】
以下、本発明にかかる吸盤の好ましい実施の形態を図面に基づいて説明する。
図１は分解された吸盤と、吸盤に取り付けられる歯ブラシホルダ（支持具）を示し、図中符号１は吸盤を示し、符号２は歯ブラシホルダを全体的に示す。
吸盤１は本体部分３と後述する連結用突起７に嵌着されるずれ止め用キャップ４とからなり、本体部分３は着色された軟質合成樹脂により緩やかな漏斗状の吸着面５を有する真空吸着部６と、真空吸着部６の外面中央部分に短寸円柱状の連結用突起７を一体成形してある。
【０００８】
そして、連結用突起７には吊持用貫通孔８が形成され、真空吸着部６の周縁近傍の一箇所には吸着させた真空吸着部６の吸着面５に外気を流入させて吸盤１の吸着を解除するための摘み９が形成されている。
連結用突起７に外嵌される上記ずれ止め用キャップ４は、透明の合成樹脂で略球形に形成されるとともに、内部には連結用突起７を収納する収納用空間１０が形成されている。
この収納用空間１０はその入口開口部分の径Ｄ１は連結用突起７の径Ｄ２に略等しいか僅かに小径になるように形成されている。
【０００９】
この収納用空間１０の入口開口部分の径Ｄ１を上記のように連結用突起７の径Ｄ２より僅かに小径にした場合でも、ずれ止め用キャップ４の中央部分の収納用空間部分１０は略球形に形成されるずれ止め用キャップ４の成形後の熱収縮により、図５に示すように連結用突起７に等しくなるように広がり、この部分でもずれ止め用キャップ４が連結用突起７から抜け外れるのが防止される。
また、ずれ止め用キャップ４の両側には連結用突起７の吊持用貫通孔８の径と略同じ幅を有するスリット１１が収納用空間１０に連通する状態で形成されており、スリット１１の内面部分には抜け止め突起１２が形成されている。
【００１０】
一方、吸盤１に装着される上記歯ブラシホルダ２は、弾性を有する合成樹脂で環状支持部１３と、環状支持部１３から左右に突出させたブラシホルダ１４と、吊持用連結孔８に嵌合される嵌着部１５とを一体成形してあり、環状支持部１３は、その内径Ｄ３は球状のずれ止め用キャップ４の外径と略等しくしてある。
上記ブラシホルダ１４は環状支持部１３の両側方に突出したブラケット１４ａとブラケット１４ａの先端部分に歯ブラシの柄（図示せず）を保持する保持部１４ｂとを一体に形成して構成されている。
吊持用連結孔８に嵌合される嵌着部１５は、環状支持部１３の内周面から中心に向けて円柱に突出形成したもので、その対面する端部間は連結用突起７径よりも狭い隙間αが形成されている。
【００１１】
上記のように形成された吸盤１に歯ブラシホルダ２を組み付ける手順を次に説明する。
先ず、図１に示すように吸盤１の本体部分３の連結用突起７からずれ止め用キャップ４を外した状態にし、歯ブラシホルダ２の環状支持部１３を変形させて嵌着部１５の先端部を前後にずらした状態にし、図２に示すように一方の嵌着部１５を連結用突起７の吊持用連結孔８に挿入する。
次に、他方の嵌着部１５を連結用突起７の吊持用連結孔８に挿入した後、図３に示すようにずれ止め用キャップ４をそのスリット１１が嵌着部１５に対面するように位置合わせした状態にして連結用突起７に押し込んで嵌着すると図４に示すように歯ブラシホルダ２が吸盤１に取り付けられる。
【００１２】
こうして吸盤１に取り付けられたブラシホルダ２は、ずれ止め用キャップ４が連結用突起７に押し込んで嵌着されると、図６に示すように、このずれ止め用キャップ４で歯ブラシホルダ２の環状支持部１３が図上左右にずれ動くのが防止される。これにより、嵌着部１５が吊持用連結孔８から不用意に抜け外れるのが防止される。
また、連結用突起７に嵌着されたずれ止め用キャップ４は、スリット１１の内面部分に設けられた抜け止め突起１２が嵌着部１５に掛合し、ずれ止め用キャップ４が連結用突起７から抜け外れるのが防止される。
【００１３】
尚、上記実施の形態では、収納用空間１０の入口開口部分の径Ｄ１を連結用突起７の径Ｄ２より僅かに小径にしてあるが、更に小径にすると、ずれ止め用キャップ４を連結用突起７に装着した時に、吊持用貫通孔８が縮径方向に変形されるので、此処に挿通した嵌着部１５が確りと保持されることになる。
また、上記実施の実施の形態では、連結用突起７の吊持用連結孔８の両側から嵌着部１５を挿入するようにした歯ブラシホルダ２を例に説明してあるが、こうしたものに限られず、嵌着部１５を吊持用連結孔８の片方から挿入する形式のものは勿論のこと、従来、一般的に用いられている吸盤の全てに本発明を実施することができるのは勿論のことである。
【００１４】
【発明の効果】
本発明は以上に説明したように、緩やかな漏斗状の吸着面を有する吸着部の外面中央部分に吊持用貫通孔を形成した連結用突起を有し、この吊持用貫通孔に挿通された吊持具部分を連結用突起に嵌合させたずれ止め用キャップで固定するようにしてあるので、吊持用貫通孔に吊持具部分を装着する時に緩やかに挿通できるようにしたものでも、ずれ止め用キャップがずれ動くのを止め、抜け落ちを防止できる。
これにより、吊持用貫通孔に支持具の基端部を挿通する組み付けが楽に行なえるとともに、吊持用貫通孔に挿入された支持具の基端部を確りと保持して、はずれにくくするという相反する問題を一挙に解決できる利点がある。
【００１５】
また、ずれ止め用キャップが連結用突起に嵌着されたときに、吊持用貫通孔を押圧して変形させるように連結用突起の収納用空間を形成したものでは、上記の効果に加えて、連結用突起の吊持用貫通孔に嵌着されたずれ止め用キャップの抜け止め効果があるとともに、吊持用貫通孔に挿入された支持具の基端部のがたつきをなくし、吊持用貫通孔に挿通された支持具の基端部を滑らかに回動させることができる利点がある。

[Problems to be solved by the invention]
In the conventional suction cup, in order to improve the workability of assembling the base end portion of the support through the through hole for suspension, the insertion between the through hole for suspension and the base end of the support is loosened. In such a case, it is easy to insert, but on the other hand, the support force of the base end of the support inserted in the through hole for suspension is weakened, and it is easy to rotate or detach easily. was there.
SUMMARY OF THE INVENTION The present invention has been proposed in view of the above problems, and can be easily assembled by inserting a base end portion of a support into a through hole for suspension, and a base end of a support inserted into the through hole for suspension. It is an object of the present invention to provide a suction cup that holds a portion firmly and is hard to come off.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a suction cup according to the present invention comprises: a suction portion having a gentle funnel-shaped suction surface; and a connection protrusion integrally formed at a central portion of an outer surface of the suction portion. Is formed with a through-hole for hanging, and a cap for preventing the slip of the hanging tool portion inserted into the through-hole for hanging is fitted to the projection for connection.
[0006]
Next, in the suction cup according to the present invention, when the cap for slippage prevention is fitted to the projection for connection, a storage space for the projection for connection is formed so as to press and deform the hanging through hole. Is also one of the features.
[0007]
Hereinafter, preferred embodiments of a suction cup according to the present invention will be described with reference to the drawings.
FIG. 1 shows a disassembled suction cup and a toothbrush holder (support) attached to the suction cup. In the drawing, reference numeral 1 indicates the suction cup, and reference numeral 2 indicates the toothbrush holder as a whole.
The suction cup 1 is composed of a main body 3 and a cap 4 for preventing slippage to be fitted to a connecting projection 7 described later. The main body 3 is made of colored soft synthetic resin and has a gentle suction surface 5 having a gentle funnel-shaped suction surface. A short cylindrical connecting protrusion 7 is integrally formed with the portion 6 and a central portion of the outer surface of the vacuum suction portion 6.
[0008]
The connecting projection 7 is provided with a suspension through-hole 8. At one location near the periphery of the vacuum suction unit 6, outside air flows into the suction surface 5 of the vacuum suction unit 6. A knob 9 for releasing the suction is formed.
The cap 4 for preventing slippage fitted to the connection projection 7 is formed of a transparent synthetic resin into a substantially spherical shape, and a storage space 10 for storing the connection projection 7 is formed inside.
The storage space 10 is formed such that the diameter D1 of the entrance opening is substantially equal to or slightly smaller than the diameter D2 of the connecting projection 7.
[0009]
Even when the diameter D1 of the entrance opening portion of the storage space 10 is slightly smaller than the diameter D2 of the connection projection 7, the storage space portion 10 in the central portion of the cap 4 is substantially spherical. Due to the thermal shrinkage of the stopper cap 4 formed after the molding, the stopper cap 4 spreads out to be equal to the connecting projection 7 as shown in FIG. Is prevented.
Slits 11 having substantially the same width as the diameter of the suspension through hole 8 of the connection projection 7 are formed on both sides of the cap 4 for slippage so as to communicate with the storage space 10. A retaining projection 12 is formed on the inner surface.
[0010]
On the other hand, the toothbrush holder 2 mounted on the suction cup 1 is fitted in an annular support portion 13 made of synthetic resin having elasticity, a brush holder 14 projecting left and right from the annular support portion 13, and a connecting hole 8 for suspension. The inner diameter D3 of the annular support portion 13 is substantially equal to the outer diameter of the spherical cap 4 for preventing slippage.
The brush holder 14 is formed by integrally forming a bracket 14a protruding to both sides of the annular support portion 13 and a holding portion 14b for holding a toothbrush handle (not shown) at a tip portion of the bracket 14a.
The fitting portion 15 to be fitted into the suspension connection hole 8 is formed in a cylindrical shape so as to project from the inner peripheral surface of the annular support portion 13 toward the center, and the diameter of the connection projection 7 is between the facing ends. A gap α narrower than that is formed.
[0011]
Next, a procedure for assembling the toothbrush holder 2 to the suction cup 1 formed as described above will be described.
First, as shown in FIG. 1, the cap 4 for preventing slippage is removed from the connecting projection 7 of the main body portion 3 of the suction cup 1, and the annular support portion 13 of the toothbrush holder 2 is deformed so that the tip end of the fitting portion 15 is formed. Are shifted to the front and rear, and one fitting portion 15 is inserted into the suspension connection hole 8 of the connection projection 7 as shown in FIG.
Next, after the other fitting portion 15 is inserted into the hanging connection hole 8 of the connection projection 7, the cap 11 for slip prevention is moved so that the slit 11 faces the fitting portion 15 as shown in FIG. 3. When the toothbrush holder 2 is attached to the suction cup 1 as shown in FIG.
[0012]
As shown in FIG. 6, the brush holder 2 attached to the suction cup 1 is fitted with the cap 4 for pushing the stopper into the projection 7 for connection as shown in FIG. The support 13 is prevented from moving left and right in the figure. As a result, the fitting portion 15 is prevented from being accidentally detached from the hanging connection hole 8.
Further, the slip-preventing cap 4 fitted to the connection projection 7 has the slip-off prevention projection 12 provided on the inner surface of the slit 11 engaged with the fitting portion 15, and the slip-prevention cap 4 is connected to the connection projection 7. Is prevented from coming off.
[0013]
In the above embodiment, the diameter D1 of the entrance opening of the storage space 10 is slightly smaller than the diameter D2 of the connection projection 7. However, if the diameter D1 is further reduced, the slip-preventing cap 4 is connected to the connection projection. When the mounting portion 7 is mounted, the hanging through hole 8 is deformed in the diameter reducing direction, so that the fitting portion 15 inserted therethrough is securely held.
Further, in the above-described embodiment, the toothbrush holder 2 in which the fitting portions 15 are inserted from both sides of the suspension connection hole 8 of the connection projection 7 is described as an example, but the present invention is not limited to such. Instead, the present invention can be applied to all commonly used suction cups as well as the type in which the fitting portion 15 is inserted from one of the hanging connection holes 8. That is.
[0014]
【The invention's effect】
As described above, the present invention has a connecting projection formed with a through hole for suspension at the center of the outer surface of the suction unit having a gentle funnel-shaped suction surface, and is inserted through the through hole for suspension. Because the hanging part is fixed with the cap for stopper fitted to the connecting projection, even when the hanging part is inserted into the through hole for hanging, it can be loosely inserted. In addition, the cap for slip prevention can be prevented from slipping and moving, and can be prevented from falling off.
This makes it easy to assemble the base end of the support through the through-hole for suspension, and securely holds the base end of the support inserted into the through-hole for suspension so that the support is hard to come off. This has the advantage that these conflicting problems can be solved at once.
[0015]
Further, in the case where the storage space for the connection projection is formed so that the suspension through-hole is pressed and deformed when the cap for slippage prevention is fitted to the connection projection, in addition to the effects described above, In addition, there is an effect of preventing the cap for slip prevention fitted in the through hole for suspension of the connecting projection, and the back end of the support tool inserted into the through hole for suspension is prevented from loosening. There is an advantage that the base end of the support inserted into the holding through hole can be smoothly rotated.
