Description

本考案は、複数車輪と車輪軸台の一体構造に関するもので、特に、遊戯もしくは運動器材の車輪、例として、キックボード、三輪車、二輪車、スケートボード、ローラースケート靴、幼児遊戯車（地面を足で蹴って移動する幼児車）、スーツケース、手押し車、カート、玩具の車、健康器具の車輪に適用し、複数個の同外径車輪を車輪軸台に一体成型し、地面との接触面を増やして、安全に走行するものである。 The present invention relates to an integrated structure of a plurality of wheels and wheel heads, and in particular, wheels for play or exercise equipment, such as kickboards, tricycles, motorcycles, skateboards, roller skate shoes, infant playwheels (ground feet Applied to wheels of suitcases, wheelbarrows, carts, toy cars, health equipment, etc., and multiple wheels with the same outer diameter are integrally molded on the wheel axle and contacted with the ground To drive safely.

今日、一般に、子どもが使用するキックボード、三輪車及び二輪車構造は、子どもの操作が悪いと、カーブ時に傾いて転倒する恐れがある。そのため、多くの車輪支持軸両外側には、外径の小さい補助輪が各々設置されている。しかし、この２個の補助輪は別に小車輪軸が枢設され、その後、車輪支持軸に固定されるため、補助輪と主輪は異なる軸を具える。 Today, in general, kickboards, tricycles and two-wheeled vehicle structures used by children are likely to tip over and fall on curves when children are poorly operated. Therefore, auxiliary wheels having a small outer diameter are installed on both outer sides of many wheel support shafts. However, since the two auxiliary wheels are separately provided with a small wheel shaft and then fixed to the wheel support shaft, the auxiliary wheel and the main wheel have different shafts.

解決しようとする問題点は、公知の技術は、製造、組立コストが増え、部品が多いため、組立に時間もかかる。更に、走行時、補助輪の車輪支持軸はぶつかりやすい上に、ぶつかると、壊れやすく、理想的でない点である。 The problem to be solved is that the known technique increases the manufacturing and assembling costs and has many parts, so that it takes time to assemble. Further, the wheel support shaft of the auxiliary wheel is easy to collide when traveling, and it is fragile if it collides, which is not ideal.

本考案は、少なくとも２個の車輪体と、１個の車輪軸台とを含む。そのうち、各車輪体は車輪軸台に設置され、車輪軸台には車輪軸孔が貫設されている。更に、各車輪体と車輪軸台は一体成型されている。各車輪体の間には車輪軸台が設置され、且つ車輪軸台の外径は各車輪体より小さいが、車輪軸台の最大外径は各車輪体と等しくてもよい。この他各車輪体の表面に異なる材質の外タイヤを設置してもよく、その外タイヤは射出成型、鋳込み成型若しくはタイヤを直接設置してもよく、これらによって、地面との接触面積が増え、安全に走行することを最も主要な特徴とする。 The present invention includes at least two wheel bodies and one wheel axle. Among them, each wheel body is installed on a wheel shaft base, and a wheel shaft hole is formed through the wheel shaft base. Furthermore, each wheel body and the wheel head stand are integrally molded. Wheel axles are installed between the wheel bodies, and the outer diameter of the wheel axles is smaller than each wheel body, but the maximum outer diameter of the wheel axles may be equal to each wheel body. In addition to this, an outer tire of a different material may be installed on the surface of each wheel body, and the outer tire may be directly injection-molded, cast-molded, or a tire, thereby increasing the contact area with the ground, The most important feature is driving safely.
