Description

本考案は、サイクリングおよび競輪用自転車のタイヤに圧縮空気を入れるエアーチャックと普通自転車、バイクおよび自動車のタイヤに圧縮空気を入れるエアーチャックとを一体にしたエアーチャックに関するものである。 The present invention relates to an air chuck in which an air chuck that puts compressed air into a tire of a bicycle for bicycles and bicycles and an air chuck that puts compressed air into tires of ordinary bicycles, motorcycles, and automobiles.

従来のサイクリングおよび競輪用自転車のタイヤに空気を入れる場合、ヨーロッパ地方や日本でも手動の空気入れ器しかなく、しかも空気を入れる場合、空気入れ器のエアーチャックのネジ部をタイヤのバルブ（虫）のネジ部に嵌合して空気を入れている。また、サイクリングおよび競輪用自転車のタイヤに空気を入れる場合、圧縮空気を入れるエアーチャックをタイヤのバルブ（虫）に押し当てて空気を入れているが、エアーチャックとタイヤのバルブとの間に圧縮空気が洩れることが多かった。 When putting air into the tires of conventional bicycles and bicycle racers, there is only a manual inflator in Europe and Japan, and when injecting air, the screw part of the air chuck of the inflator is inserted into the tire valve (insect). It is fitted into the screw part and air is put in. In addition, when putting air into the tires of cycling and bicycle race bicycles, the air chuck that puts compressed air is pressed against the tire valve (insect) and the air is put in, but the air is compressed between the air chuck and the tire valve. The air often leaked.

従来のサイクリングおよび競輪用自転車のタイヤに空気を入れる場合、圧縮空気を入れるエアーチャックをタイヤのバルブ（虫）に押し当てて空気を入れているが、タイヤのバルブに押し当てる際、圧縮空気が漏れながら空気を入れている現状である。そこで、圧縮空気が漏れることなく、空気を入れられるエアーチャックが望まれていた。
そこで、本考案は、前記望まれているエアーチャックを実現し、しかも、普通自転車、バイクおよび自動車のタイヤにも併用できる圧縮空気を入れるエアーチャックを考案することを目的とするものである。
さらに、エアーチャックが冷たくなく、持ちやすい握り部を設けることも併せ、目的としている。When putting air into the tires of conventional bicycles and bicycle races, the air chuck that puts compressed air is pressed against the tire valve (insect), and the air is put in. It is the present condition that air is put in while leaking. Therefore, there has been a demand for an air chuck that can contain air without leaking compressed air.
SUMMARY OF THE INVENTION Accordingly, the present invention aims to devise an air chuck that realizes the desired air chuck, and that contains compressed air that can be used together with tires of ordinary bicycles, motorcycles, and automobiles.
Another object is to provide a grip portion that is easy to hold and the air chuck is not cold.

本考案は、上記目的を達成するために、エアーチャック本体のケーシング１０の上部にサイクリングおよび競輪用自転車のエアーチャック１５を取付け、前記エアーチャック１５は、長い筒体４の下部の溝部にパッキング３をはめ込み、締付け部４ｂを回して、長い筒体４のネジ部４ａをケーシング１０の上部のネジ部に嵌合し、長い筒体４の上部の溝部にパッキング５をはめ込み、中空のキャップ６のネジ部６ａを長い筒体４の上部のネジ部に嵌合し、そして、ケーシング１０の下部に普通自転車、バイクおよび自動車用エアーチャック１６を取付け、前記エアーチャック１６は、短い筒体７の上部の溝部にパッキング８をはめ込み、短い筒体７の締付け部７ｂを回して、短い筒体７のネジ部７ａをケーシング１０の下部のネジ部に嵌合し、前記パッキング３にピン１をはめ込み、また、前記パッキング８にピン２をはめ込み、ピン１とピン２の間にスプリング９をはめ込みながら、ケーシング１０の中空部にピン１とピン２をはめ込んだバネ９を挿入したもので、ピン１は、押棒２０の全体の形状を正面視きのこ状に形成し、しかも扁平に形成して、押棒２０の上端に窪み部を設けた押接部２２を形成し、押棒２０の上端より正面視なだらかな肩部２３を形成し、押棒２０の下部２４を正面視少し細くし、押棒２０の下端に当接部２１を形成し、当接部２１の下部に突起部２１ａを形成して、ピン２は、押棒３０の全体の形状を棒状にし、しかも扁平に形成して、押棒３０の上端に窪み部を設けた押接部３２を形成し、押棒３０の上端より少し下に段部３３を形成し、押棒３０の下端に当接部３１を形成し、当接部３１の下部に突起部３１ａを形成して、上下の押棒２０，３０の当接部２１，３１にスプリング９をはめ込んだことを特徴とするエアーチャックからなるものである。 In order to achieve the above object, the present invention attaches an air chuck 15 for cycling and bicycle racing to the upper part of the casing 10 of the air chuck body, and the air chuck 15 is packed in the groove part at the lower part of the long cylindrical body 4. And tighten the tightening portion 4b to fit the screw portion 4a of the long cylinder 4 into the screw portion at the top of the casing 10, and fit the packing 5 into the groove at the top of the long cylinder 4 so that the hollow cap 6 The screw portion 6a is fitted to the upper screw portion of the long cylindrical body 4, and the air chuck 16 for ordinary bicycles, motorcycles and automobiles is attached to the lower portion of the casing 10, and the air chuck 16 is connected to the upper portion of the short cylindrical body 7. The packing 8 is fitted in the groove portion of the short cylinder 7, and the tightening portion 7b of the short cylinder 7 is turned so that the screw portion 7a of the short cylinder 7 is fitted to the screw portion at the bottom of the casing 10. The pin 1 is fitted into the packing 3, the pin 2 is fitted into the packing 8, and the spring 9 is fitted between the pin 1 and the pin 2, and the spring 9 is fitted with the pin 1 and the pin 2 into the hollow portion of the casing 10. The pin 1 forms the entire shape of the push rod 20 in a mushroom shape when viewed from the front, and is formed flat to form a pressing portion 22 having a depression at the upper end of the push rod 20, A gentle shoulder portion 23 is formed from the upper end of the push rod 20, the lower portion 24 of the push rod 20 is slightly narrowed in front view, a contact portion 21 is formed at the lower end of the push rod 20, and a protrusion is formed at the lower portion of the contact portion 21. 21a is formed, and the pin 2 is formed into a rod-like shape as a whole of the push rod 30 and is formed flat to form a pressing portion 32 having a depression at the upper end of the push rod 30, and from the upper end of the push rod 30 A step 33 is formed slightly below the push rod 30. An air characterized in that a contact portion 31 is formed at the lower end, a protrusion 31a is formed at a lower portion of the contact portion 31, and a spring 9 is fitted into the contact portions 21, 31 of the upper and lower push rods 20, 30. It consists of a chuck.

そして、ピン１の押棒２０の全体の形状を正面視きのこ状に形成し、押棒２０の上端より正面視なだらかな肩部２３を形成して、押棒２０がパッキング３の内径の中心に位置するようにしている。また、押棒２０のなだらかな肩部２３とパッキング３の内径との間は、あまり隙間がないので、タイヤのバルブに本考案のピン１を押し付ける際、ピン１がふらつき、作業がしにくくなることもない。また、ピン１の押棒２０およびピン２の押棒３０の形状を扁平に形成して、さらに、押棒２０の下部２４を正面視少し細くして、押棒２０および押棒３０とパッキング３および８との間に隙間を設けて、圧縮空気が大量に流れることになる。 Then, the entire shape of the push rod 20 of the pin 1 is formed in a mushroom shape when viewed from the front, and a gentle shoulder portion 23 is formed from the upper end of the push rod 20 so that the push rod 20 is positioned at the center of the inner diameter of the packing 3. I have to. In addition, since there is not much clearance between the gentle shoulder 23 of the push rod 20 and the inner diameter of the packing 3, when the pin 1 of the present invention is pressed against the tire valve, the pin 1 will fluctuate and work will be difficult. Nor. Further, the shape of the push rod 20 of the pin 1 and the push rod 30 of the pin 2 is formed flat, and the lower portion 24 of the push rod 20 is slightly narrowed when viewed from the front, and the space between the push rod 20 and the push rod 30 and the packings 3 and 8 is reduced. As a result, a large amount of compressed air flows.
