Description

本考案は、子供達が手を使って行う球技に使用されるゴムボール、特にそのバルブコアの改良に関する。   The present invention relates to an improvement of a rubber ball, particularly a valve core, used in a ball game performed by children using hands.

このように手で扱う球技、例えば、ドッチボール、バスケットボール、ソフトバレーボール、ハンドボール(いずれも非公式)に使用されるゴムボールは、全体がブチルゴムのような合成ゴムで作られる。一方ゴムボールのバルブコアは、ボールへの圧搾空気の注入及び封じ込めを行うチェックバルブとして機能するようにラテックス、つまり天然ゴムで作られる。バルブコアは、ゴムボールに明けられた穴から差し込まれて、ゴムボールの内面に付けられた合成ゴム製のバルブホルダに嵌め込まれる。バルブコアの一部は、ゴムボールの穴内に留まってボールの表面に露出する。   The rubber balls used in handball games such as Dotball, basketball, soft volleyball, and handball (unofficial) are all made of synthetic rubber such as butyl rubber. On the other hand, the valve core of the rubber ball is made of latex, that is, natural rubber so as to function as a check valve for injecting and containing compressed air into the ball. The valve core is inserted through a hole opened in the rubber ball and is fitted into a synthetic rubber valve holder attached to the inner surface of the rubber ball. A part of the valve core remains in the hole of the rubber ball and is exposed on the surface of the ball.

したがって、球技中、露出したバルブコアに手が触れたり、或いは圧搾空気を注入する場合に針をバルブコアに差し易くするためにバルブコアを濡らす際にバルブコアに触れる必要があったりする。そのような場合に、ゴムによるアレルギー、ラテックスアレルギーが起こることが知られている。ラテックスアレルギーは、バルブコアの原料であるゴムのタンパク質がアレルゲン(原因物質)となって起こることも知られている。 Therefore, during a ball game, a hand may touch the exposed valve core, or when injecting compressed air, it may be necessary to touch the valve core when the valve core is wetted to facilitate insertion of the needle into the valve core. In such a case, it is known that rubber allergy and latex allergy occur. Latex allergy is also known to occur as an allergen (causative substance) of rubber protein, which is a raw material for valve cores.

本考案の目的は、ゴムボールのバルブコアに接触してもアレルギーを起こさないように工夫した、ゴムボール用のバルブコアを提供することにある。   An object of the present invention is to provide a valve core for a rubber ball that is devised so as not to cause allergies even when it contacts the valve core of a rubber ball.

この目的は、本考案によれば、ゴムボールの穴内に納まる上部分と、ゴムボールの内面に付けられたバルブホルダに嵌め込まれる円形フランジ付下部分と、中心に設けられた針受け穴と、針受け穴から延び、針からの圧搾空気のゴムボールへの注入によって開くスリットとを有するバルブコアにおいて、上部分を合成ゴムとし、下部分をラテックスゴムとしたことを特徴とするゴムボール用のバルブコアを提供することによって達成される。   The purpose of the present invention is, according to the present invention, an upper part that fits in the hole of the rubber ball, a lower part with a circular flange that is fitted into a valve holder attached to the inner surface of the rubber ball, a needle receiving hole provided in the center, A valve core for a rubber ball having a slit extending from a needle receiving hole and opened by injection of compressed air from the needle into the rubber ball, wherein the upper part is made of synthetic rubber and the lower part is made of latex rubber Is achieved by providing

本考案によれば、ゴムボールの穴内に納まる上部分はボールの表面に露出していて、球技中手がこれに触れるけれども、ゴムボールと同様の合成ゴムで作られているため、アレルギーを起こすことはない。またバルブコアの下部分は、ラテックスゴムで作られているから通常のバルブコアと同様に圧搾空気の注入、閉じ込めを行うバルブ機能を遺憾なく発揮する。   According to the present invention, the upper part that fits in the hole of the rubber ball is exposed on the surface of the ball and the middle hand of the ball game touches it, but because it is made of synthetic rubber similar to the rubber ball, it causes allergies There is nothing. In addition, since the lower part of the valve core is made of latex rubber, it exerts the valve function of injecting and confining compressed air like a normal valve core.

図を参照すると、本考案によるバルブコア1は、ドッチボール、バスケットボール、ソフトバレーボール、ハンドボール(いずれも非公式)に使用されるゴムボール2のいずれにもチェックバルブとして用いられる。ゴムボール2は、全体が、触れてもアレルギーを起こさないブチルゴムのような合成ゴムで作られる。一方ゴムボールのバルブコア1は、図2に示すように、ゴムボール2に明けられた穴3から差し込まれて、ゴムボールの内面に付けられた合成ゴム製のバルブホルダ4に嵌め込まれる。バルブコアの一部は、ゴムボールのバルブコア穴3内に留まってボールの表面に露出する。   Referring to the figure, the valve core 1 according to the present invention is used as a check valve for any of the rubber balls 2 used for Dotball, basketball, soft volleyball, and handball (all are unofficial). The rubber ball 2 is made of a synthetic rubber such as butyl rubber that does not cause allergies even when touched. On the other hand, as shown in FIG. 2, the rubber ball valve core 1 is inserted through a hole 3 formed in the rubber ball 2 and fitted into a synthetic rubber valve holder 4 attached to the inner surface of the rubber ball. A part of the valve core remains in the valve core hole 3 of the rubber ball and is exposed on the surface of the ball.

詳述すると、図2に示すように、本考案によるバルブコア1は、ゴムボール2の穴3内に納まる、合成ゴムの上部分5と、ゴムボール2の内面に付けられたバルブホルダ4に嵌め込まれるラテックスゴムの円形フランジ付下部分6と、中心に設けられた針受け穴7と、針受け穴7から延び、針(図示せず)からの圧搾空気のゴムボールへの注入によって開くスリット8(図3及び4)と、を有する。バルブコア1は、これを構成する合成ゴムの上部分5とラテックスゴムの円形フランジ付下部分6が二体として成形されて互いに接合され、その状態で加硫することによって一体の製品として提供される。好ましい実施形態では、上部分5は円形フランジ付下部分6の中心部に入り込んだ一体の筒部8を有し、針受け穴7は、上部分5から筒部8内に延びる。   More specifically, as shown in FIG. 2, the valve core 1 according to the present invention is fitted into a synthetic rubber upper portion 5 that fits in the hole 3 of the rubber ball 2 and a valve holder 4 attached to the inner surface of the rubber ball 2. The lower part 6 of latex rubber with a circular flange, the needle receiving hole 7 provided in the center, and the slit 8 extending from the needle receiving hole 7 and opened by injection of compressed air from the needle (not shown) into the rubber ball (FIGS. 3 and 4). The valve core 1 is provided as an integral product by forming the upper part 5 of the synthetic rubber and the lower part 6 with the latex flange with a circular flange formed into two bodies, joined together, and vulcanized in that state. . In a preferred embodiment, the upper portion 5 has an integral tube portion 8 that enters the center of the lower portion 6 with a circular flange, and the needle receiving hole 7 extends from the upper portion 5 into the tube portion 8.

本考案によれば、ゴムボールの穴内に納まり、ボールの表面に露出していているバルブコアの上部分がゴムボールと同様の合成ゴムで作られているため、それに触れてもアレルギーを起こすことはない。バルブコアの円形フランジ付下部分は、ラテックスゴムで作られているから、ゴムボールへの圧搾空気の注入及び閉じ込めに関し在来のバルブコアと同様に機能する。   According to the present invention, because the upper part of the valve core that fits in the hole of the rubber ball and is exposed on the surface of the ball is made of the same synthetic rubber as the rubber ball, it does not cause allergies even if you touch it. Absent. Since the lower flanged portion of the valve core is made of latex rubber, it functions in the same way as a conventional valve core with respect to the injection and containment of compressed air into the rubber ball.
