Abstract

【課題】硬式テニスボールの空気圧の減少を防ぐための装置を提供する。【解決手段】円筒状の容器の一端を密閉し、他端にネジを付けたテニスボールより大きな蓋を付ける。その蓋または容器に弁の付いた管を付け、蓋と容器の間にパッキンを付け容器内部の気圧を高めたことを特徴とする。普通は開缶すると２、３日しか空気圧が持たないが、この装置に入れると２〜３ヶ月経過しても硬式テニスボールの空気圧が維持される。【選択図】図１An apparatus for preventing a decrease in air pressure of a hard tennis ball is provided. One end of a cylindrical container is sealed and a lid larger than a tennis ball with a screw attached to the other end is attached. A tube with a valve is attached to the lid or the container, and packing is provided between the lid and the container to increase the pressure inside the container. Normally, when the can is opened, it has air pressure for only a few days, but when it is put in this device, the air pressure of the hard tennis ball is maintained even after a few months have passed.

Description

硬式テニスボールの空気圧の減少を防ぐための装置の考案である。A device for preventing a decrease in air pressure of a tennis ball.

硬式テニスボールのゴムの膜を厚くして空気が漏れるのを防いでいた。The rubber film of the hard tennis ball was thickened to prevent air from leaking.

高気圧の缶に入っている硬式テニスボールは開缶すると徐々に硬式テニスボール内の空気が抜けていき使えなくなってしまう。また、従来のようにゴムの膜を厚くすると、練習では使えても試合には使えない欠点がある。When the tennis ball in a high pressure can is opened, the air inside the tennis ball gradually escapes and becomes unusable. Also, if the rubber film is made thicker as in the past, there is a disadvantage that it can not be used for games even if it can be used for practice.

硬式テニスボールを高気圧の容器に入れる。Place the tennis ball in a high pressure container.

硬式テニスボールを考案した装置に入れると、長時間硬式テニスボールの空気圧が維持される。When put in the device that devised a hard tennis ball, the air pressure of the hard tennis ball is maintained for a long time.

円筒状の容器の一端を密閉し、他端にネジを付けたテニスボールより大きな蓋を付ける。その蓋または容器に弁の付いた管を付け、蓋と容器の間にパッキンを付けたことを特徴とする装置。Seal one end of the cylindrical container and attach a lid larger than a tennis ball with a screw on the other end. A device characterized by attaching a pipe with a valve to the lid or the container and attaching a packing between the lid and the container.

普通は開缶すると２、３日しか空気圧が持たないが、この装置に入れると２〜３ヶ月経過しても硬式テニスボールの空気圧が維持される。Normally, when the can is opened, it has air pressure for only a few days, but when it is put in this device, the air pressure of the hard tennis ball is maintained even after a few months have passed.

硬式テニスボールの経費が削減される。また、ごみの削減になるので環境にも良い。Costs for rigid tennis balls are reduced. In addition, it is good for the environment because it reduces waste.

硬式テニスボール空気圧維持装置を正面から見た断面図である。図２を一点鎖線ａｂで切断し、矢印側から見た断面図である。  It is sectional drawing which looked at the hard tennis ball air pressure maintenance device from the front. FIG. 3 is a cross-sectional view of FIG. 2 taken along the dashed line ab and viewed from the arrow side. 硬式テニスボール空気圧維持装置を上から見た図である。  It is the figure which looked at the hard tennis ball air pressure maintenance device from the top. 硬式テニスボール空気圧維持装置の斜視図である。  It is a perspective view of a hard tennis ball air pressure maintenance device.
