Abstract

Provided is a skateboard which is configured from a front wheel, a rear wheel, and a board and is capable of moving forward, without the rider having to put a foot against the ground, according to vertical shifting of the rider's body weight. The axle of the rear wheel is positioned away from the center of the wheel so as to create a vertical swinging motion for the board, and the rider would shift his body weight vertically in synch with the vertical swinging of the board such that the board is pushed down and springs back up repeatedly, thereby enabling forward motion.

Description

自走式スケートボードSelf-propelled skateboard
　本発明は、前輪と後輪、及び両足が載るボードで構成されたスケートボードに関するものである。 The present invention relates to a skateboard composed of a front wheel, a rear wheel, and a board on which both feet are placed.
従来の技術Conventional technology
　従来の自走式の前輪と後輪、及びボードで構成されるスケートボードにおいては、連結した二枚の板それぞれに自在車輪を持つキャスターボードのように、体を左右に振り、前輪を左右交互に振って進むようになっている。しかしながら、このような構造では、スケートボードを持続的に力強く前進させることは困難であるとういう問題がある。　 In a conventional skateboard composed of front and rear wheels and a board, the body is swung left and right like a caster board with free wheels on each of the two connected plates, and the front wheels are alternately left and right. To move forward. However, with such a structure, there is a problem that it is difficult to continuously and strongly advance the skateboard. *

　本発明は、このような課題を解決するもので、乗り手が足を地面に着けることなく、乗り手の体重の上下移動という、より自然で力強く持続性がある動きをスケートボードの前方への推進力に変えることを目的とするものである。 The present invention solves such a problem, and the forward driving force of the skateboard is a more natural, powerful and sustainable movement of the rider's weight up and down without putting the foot on the ground. The purpose is to change to
　添付の図面の図３はこのスケートボードの後輪２の３－３の拡大したスケールの縦断面である。本来、車輪の中心にあるべき車軸１を中心から離れた位置に取り付けることにより、ボード４の上下の揺れを作り出し、以下に述べる動作を乗り手が行うことにより、乗り手が足を地面に着けることなく前進することを要旨とするものである。 Figure 3 of the attached drawing is a longitudinal section of an enlarged scale 3-3 of the rear wheel 2 of this skateboard. By attaching the axle 1 that should originally be the center of the wheel at a position away from the center, the board 4 can be shaken up and down, and the rider can perform the following actions without the rider putting his feet on the ground. The main point is to move forward.
　図１に示されるように、後輪２の車軸１が地面から最も離れたポジションから、乗り手が体をやや前方に保ちながら、力強く体重を下方に移す事により、ボード４が押し下げられ、車軸１が前下方に動き、車輪が回転し、車軸１が地面から最も近い図２のポジションになる。その際生じる慣性による跳ね返りに従って、乗り手が体重を上方に力強く移すことにより、図１のポジションに戻る。乗り手がこの運動をボード４の上下の揺れに同期させながら、連続して行うことにより、このスケートボードは前方への推進力を得る。 As shown in FIG. 1, the board 4 is pushed down from the position where the axle 1 of the rear wheel 2 is farthest from the ground, and the rider moves the weight strongly while keeping the body slightly forward. Moves forward and downward, the wheels rotate, and the axle 1 is in the position of FIG. 2 closest to the ground. In accordance with the rebound caused by the inertia generated at that time, the rider moves his weight strongly upward to return to the position shown in FIG. The skateboard gains forward propulsion by the rider performing this motion continuously while synchronizing this motion with the up and down shaking of the board 4.
　従来のスケートボードに見られる速く滑らかな走行性を目指すのではなく、構造を複雑にすることなく、乗り手がより自然に体全体を使い、楽しく短時間で高い運動量を得られる為に、遊具としてはもちろん、ダイエット器具としても使用できるという利点がある。 Rather than aiming for the fast and smooth running characteristics found in conventional skateboards, the rider can use the whole body more naturally and enjoy high momentum in a short time without complicating the structure. Of course, there is an advantage that it can be used as a diet device.

　乗り手が体重を上下移動させることにより、足を地面に着けることなく前方に推進するという目的を、構造を複雑にすることなく実現した。 The rider moved his weight up and down to achieve the goal of propelling forward without wearing the ground without complicating the structure.
　前輪６と後輪２、及びボード４があり、後輪２の車輪の中心から外れた所を貫く車軸１がある。 There are a front wheel 6, a rear wheel 2, and a board 4, and there is an axle 1 that penetrates the center of the wheel of the rear wheel 2.
　図２の車軸１が地面から最も近いポジションにある時、ボード４が地面と平行になるように、後輪２の直径は、前輪６の直径よりも大きくなる。 When the axle 1 in FIG. 2 is in the position closest to the ground, the diameter of the rear wheel 2 is larger than the diameter of the front wheel 6 so that the board 4 is parallel to the ground.
　後輪２の直径が大きいほど乗り手の運動量は増加する。 ) The rider's momentum increases as the diameter of the rear wheel 2 increases.
　ボード４に弾性カーボンなどの弾性素材を用いることにより、地面からの衝撃を吸収し、その反発力を利用することにより、より効率的に走行することが出来る。 By using an elastic material such as elastic carbon for the board 4, it is possible to travel more efficiently by absorbing the impact from the ground and utilizing the repulsive force.

　前輪６と後輪２に、それぞれタイヤ８とタイヤ３が取り付けられている。 The tire 8 and the tire 3 are attached to the front wheel 6 and the rear wheel 2, respectively.
　前輪６は、車軸７が車輪の中心を貫く通常の車輪である。 The front wheel 6 is a normal wheel in which the axle 7 penetrates the center of the wheel.
　前輪６の車軸７、後輪２の車軸１は、それぞれボード４に固定されている。 The axle 7 of the front wheel 6 and the axle 1 of the rear wheel 2 are fixed to the board 4 respectively.
