Description

本発明は、車両用のタイヤに関するものである。  The present invention relates to a vehicle tire.

車両用タイヤは、リム及びその外周に装着されたタイヤ、タイヤの中に空気を入れたチューブから構成されるチューブタイヤと、チューブがなく、リムに密着装着されるチューブレスタイヤに大別される。タイヤの色は多くは黒色であり、稀に白色等の色がある。非特許文献「特願２０１０−１９８２７１」では透明色が提案されている。チューブの色は、従来品はすべて黒色であり、非特許文献「特願２０１０−１９８２７１」では濃色が提案されている。以下の文献にあるとおり、チューブの代わりに球体をタイヤ内に挿入する、及びヘリウムガスをチューブ内、又は球体内に充填させる発明は既に提案されている。  Vehicle tires are broadly classified into rims, tires mounted on the outer periphery thereof, tube tires composed of tubes in which air is put in the tires, and tubeless tires that have no tubes and are closely attached to the rims. The tire is mostly black and rarely has a color such as white. A non-patent document “Japanese Patent Application No. 2010-198271” proposes a transparent color. As for the color of the tube, the conventional products are all black, and a non-patent document “Japanese Patent Application No. 2010-198271” proposes a dark color. As described in the following documents, an invention has been proposed in which a sphere is inserted into a tire instead of a tube, and helium gas is filled into the tube or the sphere.

特願２０１０−１９８２７１Japanese Patent Application No. 2010-198271

車両には前面、後面には通常ライトや反射板などが設置され、夜間走行中には対向車や後続車にその存在を知らしめる手段となっている。ところが車両側面から光を発射或いは反射するものはほとんどなく、特に自転車において安全面で問題がある。光量の少ないＬＥＤライトが普及する中で、これを補う安全確保手段が望まれる。  The vehicle is usually equipped with lights and reflectors on the front and rear, which are used as a means to inform oncoming vehicles and subsequent vehicles of their presence during night driving. However, there are few things that emit or reflect light from the side of the vehicle, which is problematic in terms of safety, particularly in bicycles. As LED lights with a small amount of light become widespread, safety ensuring means to compensate for this is desired.

チューブの代わりに球体をタイヤ内に挿入する発明はあるが、それらをタイヤの外側から蛍光色として目視で確認できるものはない。球体を挿入したものは、パンク修理の際にパンク箇所を特定できないので、タイヤをすべてリムから外さないと修理が出来ない。この場合複数の球体が周囲に散乱してしまう。  Although there are inventions in which spheres are inserted in the tire instead of tubes, there is nothing that can be visually confirmed from the outside of the tire as a fluorescent color. Since the puncture location cannot be specified when the puncture is repaired, the sphere cannot be repaired without removing all the tires from the rim. In this case, a plurality of spheres are scattered around.

チューブの形状が球体である場合、球体間に隙間が出来やすく、これが凹凸となり、タイヤ表面に伝わり振動となる。  When the shape of the tube is a sphere, a gap is easily formed between the spheres, which becomes uneven and is transmitted to the tire surface and becomes a vibration.

車両は常に軽量化を求められており、特にレース仕様の車両においては僅かな重量差が性能に影響する。  Vehicles are always required to be reduced in weight, and a slight difference in weight affects performance, particularly in race-specification vehicles.

本発明は上記課題を解決するため、タイヤの色を透明又は半透明色とし、タイヤの内側、又はその中に収納されるチューブ表面に蛍光塗料を施すこととした。  In order to solve the above-mentioned problems, the present invention uses a transparent or translucent color of the tire and applies a fluorescent paint to the inside of the tire or the surface of the tube accommodated therein.

またチューブをリムに近接する本体チューブ部と本体チューブ外周を取り囲むように設置された複数の分割チューブ部に分離し、分割チューブ部の形状を円柱形とした。また分割チューブ部内にヘリウムガスを充填した。  Further, the tube was separated into a main body tube portion close to the rim and a plurality of divided tube portions installed so as to surround the outer periphery of the main body tube, and the shape of the divided tube portion was a cylindrical shape. Further, helium gas was filled in the divided tube portion.

タイヤの色が透明又は半透明であり、タイヤの内側又はチューブの表面に蛍光塗料を施すことにより、夜間走行中、車両側面に大きな輪が２つ浮き出され、当該車両の存在を際立たせることができる。また、前方及び後方からも露出したタイヤ部分が光り、対向車や後続車の注意を促すことが可能となる。  The color of the tire is transparent or translucent, and by applying fluorescent paint on the inside of the tire or the surface of the tube, two large wheels are raised on the side of the vehicle during night driving, and the presence of the vehicle can stand out. it can. Moreover, the tire part exposed from the front and back also shines, and it becomes possible to call attention of an oncoming vehicle and a following vehicle.

チューブを分割式とすることにより、単体のチューブがパンクしても他が機能するので走行が可能である。また運転者が分割チューブを携帯することで、パンク修理が安価であり且つ容易となる。更に従来どおりの本体チューブはリム周囲にあるので、タイヤ圧の微調整は可能である。  By making the tube into a split type, even if a single tube is punctured, the other functions so that traveling is possible. In addition, when the driver carries the divided tube, puncture repair is inexpensive and easy. Furthermore, since the conventional body tube is around the rim, the tire pressure can be finely adjusted.

タイヤの外側からパンク箇所を目視で確認でき、タイヤ全体をリムから外すことなく迅速なパンク修理が可能となる。  The puncture location can be visually confirmed from the outside of the tire, and quick puncture repair is possible without removing the entire tire from the rim.

分割チューブ部の形状を円柱形状とすることで、タイヤ内に隙間なくチューブが収納され、凹凸が最小限に抑えられることにより振動の発生が抑制される。  By making the shape of the divided tube portion a columnar shape, the tube is accommodated in the tire without any gap, and the occurrence of vibration is suppressed by minimizing the unevenness.

また本体チューブ部、及び分割チューブ部内にヘリウムガスを充填することにより、軽量化及びタイヤ内の熱の放出に効果がある。  In addition, filling the main body tube portion and the divided tube portion with helium gas is effective in reducing the weight and releasing the heat in the tire.

タイヤの色が透明又は半透明色であり、タイヤの内側又はチューブ表面に蛍光塗料が施してある。チューブはリムに近接する本体チューブ部と本体チューブ外周を取り囲むように設置された複数の分割チューブ部から成り、分割チューブ部は円柱形状である。本体チューブ部及び分割チューブ部は、ヘリウムガスが充填されている。  The tire is transparent or translucent, and a fluorescent paint is applied to the inside of the tire or the tube surface. The tube is composed of a main body tube portion close to the rim and a plurality of divided tube portions installed so as to surround the outer periphery of the main body tube, and the divided tube portion has a cylindrical shape. The main body tube portion and the divided tube portion are filled with helium gas.

図１は、本発明の１実施例であって、自転車のタイヤを示している。１．リムはアルミ等の金属製又はカーボンファイバー等により強化された樹脂製である。リムに装着された２．タイヤはポリエチレン、ナイロン、その他合成ゴム等の透明又は半透明色の素材である。リムに近接する３．本体チューブ部は従来型のチューブと同様にリムの外周を一体的に被っている。４．分割チューブ部は、本体チューブ部とタイヤ内側の間に位置しており、弾性を持ち、適性なタイヤ内圧を保ち、且つ各々の分割チューブ部間に隙間が発生しないよう容積及び壁厚さが設定されている。分割チューブ部の表面には蛍光塗料が塗布され、タイヤの外側から目視した時、容易に各々の固体を識別できる。分割チューブ部の素材は従来どおりの合成ゴム製、又はポリウレタン等の伸縮性をもつ樹脂製でもよい。  FIG. 1 shows a bicycle tire according to an embodiment of the present invention. 1. The rim is made of metal such as aluminum or resin reinforced with carbon fiber or the like. 1. Mounted on the rim The tire is a transparent or translucent material such as polyethylene, nylon, or other synthetic rubber. 2. Close to the rim The main body tube portion integrally covers the outer periphery of the rim in the same manner as a conventional tube. 4). The divided tube part is located between the main body tube part and the inside of the tire, has elasticity, maintains appropriate tire internal pressure, and sets the volume and wall thickness so that no gap is generated between each divided tube part Has been. A fluorescent paint is applied to the surface of the divided tube portion, and each solid can be easily identified when viewed from the outside of the tire. The material of the divided tube portion may be a conventional synthetic rubber or a stretchable resin such as polyurethane.

図２は、分割チューブ部の拡大図である。円柱形の形状であり、タイヤ内側との接触面に隙間が生じにくい。内部は５．ヘリウムが充填されている。パンク修理の際は、パンクした分割チューブ部のみを廃棄処分とし、新たな分割チューブ部を挿入するだけの簡便な作業となる。  FIG. 2 is an enlarged view of the divided tube portion. It is a cylindrical shape, and it is difficult for a gap to be formed on the contact surface with the tire inner side. Inside is 5. Helium is filled. At the time of puncture repair, only the punctured divided tube portion is disposed of and discarded, and a new work is simply performed by inserting a new divided tube portion.

車両の内でも自転車の夜間走行は極めて危険であり、前照灯、尾灯、反射板等の装備をもってしても、その存在感を他の走行車両に知らしめる手段としては乏しい。近年ＬＥＤ照明が普及し、光量が更に下がるといったことも問題となっている。特に側面からの視認性は低く、塾帰りの子供達等の安全を確保しているとは言い難い。タイヤ全体が蛍光塗料により光って見えれば、側面からの視認性は格段に上がり、大きな２つの輪が移動していく様は他の走行車両の運転者の注意を大きく引き付ける。  Even in a vehicle, it is extremely dangerous to run a bicycle at night, and even if equipped with a headlight, a taillight, a reflector, etc., it is a poor means for informing other traveling vehicles of its presence. In recent years, LED lighting has become widespread, and the amount of light further decreases. In particular, the visibility from the side is low, and it is difficult to say that the safety of the children who return to the school is ensured. If the entire tire looks shining with fluorescent paint, the visibility from the side will be greatly improved, and the movement of two large wheels will greatly attract the attention of the driver of the other traveling vehicle.

パンクは車両のトラブルでは比率が高い方である。特に自転車においては、完全に走行不能となってしまうことも多く、自動車のようにスペアタイヤの準備もない。当該発明により、小さな携帯用パーツとして運転者が携帯し、パンクの際には容易にその箇所を判別し、その場で修復が可能となる。  Punk is the higher percentage of vehicle troubles. In particular, in a bicycle, it is often impossible to run completely, and no spare tire is prepared as in a car. According to the present invention, the driver carries it as a small portable part, and in the case of puncture, the part can be easily identified and repaired on the spot.

またヘリウムは空気より比重が軽く、熱伝導性も高いため、限界に挑むレースなどの際には軽量化、放熱性等に貢献する。  In addition, helium has a lower specific gravity and higher thermal conductivity than air, contributing to weight reduction and heat dissipation in races that challenge the limits.
