従来は、自転車のタイヤチューブに空気を補充するためには、停止した上で手動式・電動式の空気ポンプを利用して行う必要があった。この不便を解消するために、走行中に自動的に空気を注入する機構が複数考案されている。
下記特許文献１では、車輪の回転によって動作するピストン式エアーポンプを、自転車フレームまたは車輪に設けることで、自動的にタイヤチューブに空気を注入し、空気ボンベで補充する不便の解消を図っている。特許文献２では、車輪に止着された渦巻状の弾性チューブをローラーで押圧することでタイヤに空気を注入するとしている。 Conventionally, in order to replenish the bicycle tire tube with air, it has been necessary to stop and use a manual or electric air pump.

上記特許文献１、２に挙げられた機構は、いずれも複雑な加工や精密な機構を必要とするため、コストが高く自転車での実現は困難である。また、いずれも自転車の車輪と本体、つまり回転部分と非回転部分の間での摺動によって空気圧縮のための動力を得ているため、走行時の抵抗が大きくなる。
The mechanisms listed in Patent Documents 1 and 2 require complicated processing and precise mechanisms, which are expensive and difficult to implement on a bicycle. Moreover, since the motive power for air compression is obtained by sliding between the bicycle wheel and the main body, that is, the rotating portion and the non-rotating portion, resistance during traveling increases.

そこで本発明は、安価で着脱が容易、かつ走行時の抵抗が小さい自転車用空気注入器具を提供し、上記問題点を解決しようとするものである。 Therefore, the present invention provides a bicycle air infusing device that is inexpensive, easy to attach and detach, and has low resistance during running, and intends to solve the above problems.

本発明では、車輪と本体の間で摺動させることなく空気を移動させ圧縮することで走行時の抵抗を低減するとともに、複雑な加工や精密な機構を用いず、安価な部材によるシンプルな構成にすることで価格面での課題についても解決する手段を提供する。
請求項１記載の発明の要旨は、車輪が回転した際にタイヤと地面が接触する領域が連続的に移動することを利用して、この間に弾性チューブを設置することで弾性チューブ内部の空気を移動させ、圧力を高めることにある。
具体的には、自転車用タイヤ外周部に取り付けられ、タイヤと地面が接触するときにはさまれることで、連続的に空気が導気される導気部と、圧縮された空気をタイヤチューブに注入する注気部を有する自転車用空気注入器具の構成である。
The present invention reduces the resistance during traveling by moving and compressing air without sliding between the wheel and the main body, and does not use complicated processing or a precise mechanism, and has a simple configuration with an inexpensive member. By doing so, it provides a means to solve the problem in terms of price.
The gist of the invention described in claim 1 is that the region where the tire and the ground are in contact with each other when the wheel rotates continuously moves the air inside the elastic tube by installing the elastic tube between them. Move and increase pressure.
Specifically, it is attached to the outer periphery of a bicycle tire and is sandwiched when the tire and the ground come into contact with each other, thereby continuously introducing air and injecting compressed air into the tire tube. This is a configuration of a bicycle air injection device having an air injecting portion.

この器具は、タイヤの空気圧が高まって以降も取り付けたまま走行すると、過剰に空気が注入されてタイヤチューブを破損する可能性がある。請求項2記載の発明は、過剰な空気の注入による破損を防ぐため、タイヤチューブの許容圧力をこえないよう調整する圧力調整弁を備えることを特長としている。
If this device is run with the tire pressure increased even after the tire pressure has increased, air may be excessively injected and the tire tube may be damaged. The invention according to claim 2 is characterized by including a pressure adjusting valve that adjusts so as not to exceed the allowable pressure of the tire tube in order to prevent damage due to excessive air injection.

導気部で空気を圧縮しても、導気部を構成する弾性チューブがタイヤと地面にはさまれた領域から外れると、圧縮された空気は逆流して解放端から流出し、圧力は大気圧に戻る。効率的に空気を補充するためには、圧縮した空気の圧力を維持できることが望まれる。請求項3記載の発明では、この問題に対応するため、空気の逆流を防ぐ逆止弁を備えることを特長としている。 Even if the air is compressed in the air guide, if the elastic tube that forms the air guide is out of the area between the tire and the ground, the compressed air flows backward and flows out from the open end, and the pressure is high. Return to atmospheric pressure. In order to efficiently replenish air, it is desirable to be able to maintain the pressure of the compressed air. In order to cope with this problem, the invention according to claim 3 is characterized by including a check valve that prevents backflow of air.

本発明の自転車用空気注入器具は、タイヤに取り付けた状態で走行することによって、自動的にタイヤチューブに空気が補充されるため、タイヤに走行できる程度の空気が入っている状態であれば、空気ポンプによって注入する必要がなくなり不便が解消される。また、車輪と自転車本体、つまり回転部分と非回転部分の間で摺動させることがないため、走行時の抵抗は小さい。空気が補充された後にはすぐに取り外すことができるため、必要のないときに走行の抵抗を生み出すこともない。部品点数も少なく、安価な部材で実現できる。 The air infusing device for bicycles of the present invention automatically replenishes the tire tube by running while attached to the tire, so that the tire has enough air to run, The inconvenience is eliminated because there is no need to inject with an air pump. In addition, since there is no sliding between the wheel and the bicycle body, that is, the rotating part and the non-rotating part, the resistance during running is small. Since it can be removed immediately after the air is replenished, it does not create resistance to travel when not needed. The number of parts is small and it can be realized with an inexpensive member.

自転車走行中に自動的にタイヤチューブに空気を補充するという目的を、容易に着脱することができるように実現した。
The purpose of automatically refilling the tire tube while riding a bicycle has been realized so that it can be easily attached and detached.

図1は、本発明の自転車用空気注入器具を前輪に取り付けた場合の側面図である。１の導気部チューブは４のタイヤの外周部に、２の注気部本体は３の空気バルブに取り付けられている。自転車を漕ぐと車輪が回転し、導気部チューブ１がタイヤ４と地面の間に開放端から順にはさまれていき、導気部チューブ１内部の空気が移動して圧力が高まっていく。この空気が注気部本体２を通じて空気バルブ３に入ることで、空気の補充ができる。
FIG. 1 is a side view when the bicycle air infusing device of the present invention is attached to a front wheel. 1 air guide tube is attached to the outer periphery of 4 tires, 2 air intake body is attached to 3 air valves. When the bicycle is run, the wheels rotate, the air guide tube 1 is sandwiched between the tire 4 and the ground in order from the open end, and the air inside the air guide tube 1 moves to increase the pressure. The air can be replenished by entering the air valve 3 through the air injection unit main body 2.

図２は、本発明の自転車用空気注入器具の断面図である。注気部本体２には、５の圧力調整弁が設置され、導気部チューブ１と注気部チューブ７の間には６の逆止弁が設置されている。導気部チューブ１がタイヤ４と地面にはさまれた領域から外れた後も、逆止弁６によって注気部チューブ７と注気部本体２の内部の空気の圧力は維持され、再度導気部チューブ１がタイヤ４と地面にはさまれて新しい空気が流れ込んだときにさらに圧力が高まっていく。この空気の圧力が、タイヤ４の内部の圧力より高くなると空気バルブ３からタイヤチューブに空気が入っていく。その際、タイヤチューブに許容された以上の圧力まで空気の圧力が高まらないよう圧力調整弁５が開いて空気を開放することによって、タイヤチューブの破損を防ぐ。
FIG. 2 is a cross-sectional view of the bicycle air injection device of the present invention. The air supply unit main body 2 is provided with 5 pressure regulating valves, and the air introduction unit tube 1 and the air supply unit tube 7 are provided with 6 check valves. Even after the air guide tube 1 is removed from the region sandwiched between the tire 4 and the ground, the check valve 6 maintains the pressure of the air inside the air inlet tube 7 and the air inlet body 2 so that it is guided again. When the air tube 1 is sandwiched between the tire 4 and the ground and new air flows, the pressure further increases. When the pressure of this air becomes higher than the pressure inside the tire 4, air enters the tire tube from the air valve 3. At that time, the pressure adjustment valve 5 is opened to release the air so that the pressure of the air does not increase to a pressure higher than that allowed for the tire tube, thereby preventing the tire tube from being damaged.

図３は、導気部チューブ１の断面形状の例である。空気が通る穴と、タイヤ４をはさんで固定できる形状をしている。
FIG. 3 is an example of a cross-sectional shape of the air guide tube 1. It has a shape that can be fixed by sandwiching the hole through which the air passes and the tire 4.

今、導気部チューブ１の空気が通る穴の内径を３ｍｍ、長さを１５０ｍｍとすると車輪が１回転するときに注気部に送られる空気の量は、（０．１５ｃｍ×０．１５ｃｍ×３．１４）×１５ｃｍ＝１．０６ｃｃとなる。注気部チューブ７の内径を１ｍｍ、長さを９０ｍｍとすると、ここにもともと入っている空気は（０．０５ｃｍ×０．０５ｃｍ×３．１４）×９ｃｍ＝０．０７ｃｃとなる。注気部本体２の内部の空洞は小さいので無視すると、１回転で（１．０６＋０．０７）/０．０７＝１６となり、１６気圧程度まで加圧することが可能である。タイヤ４の標準空気圧は、２５０ｋPa〜７００ｋPa（約２．５〜７気圧）であることから、十分に対応することができる。 Now, assuming that the inner diameter of the hole through which the air of the air guide section tube 1 passes is 3 mm and the length is 150 mm, the amount of air sent to the air inlet section when the wheel makes one rotation is (0.15 cm × 0.15 cm × 3.14) × 15 cm = 1.06 cc. If the inner diameter of the air inlet tube 7 is 1 mm and the length is 90 mm, the air originally contained here is (0.05 cm × 0.05 cm × 3.14) × 9 cm = 0.07 cc. If the cavity inside the air supply unit body 2 is small, ignoring it becomes (1.06 + 0.07) /0.07=16 in one rotation, and it is possible to pressurize up to about 16 atmospheres. Since the standard air pressure of the tire 4 is 250 kPa to 700 kPa (about 2.5 to 7 atm), the tire 4 can sufficiently cope with it.

導気部チューブの穴の内径を大きくすることで、より早く空気を補充することができる。また、タイヤのトレッド面の形状によっては、タイヤと地面にはさまれた領域が連続的でなくなるため、効果的に空気を移動して圧縮させることが難しくなることが考えられる。この場合には、やや固い材質のチューブを使用することや、タイヤとチューブの間に固い板状の部材を挟むことで、不都合を解消することができる。 By increasing the inner diameter of the hole of the air guide tube, air can be replenished more quickly. Further, depending on the shape of the tread surface of the tire, the region sandwiched between the tire and the ground may not be continuous, and it may be difficult to effectively move and compress the air. In this case, the inconvenience can be solved by using a tube made of a slightly hard material or sandwiching a hard plate-like member between the tire and the tube.
