本考案は、三輪車構造に関する。 The present invention relates to a tricycle structure.
【0002】[0002]
公知の幼児向け自転車には、安定が求められるため、三輪車構造がある。この 車体の中央骨体前方にはフロントフォークがあり、そのフロントフォーク上方に はハンドルが設置される。また下方には前輪が設置され、前輪の車輪軸中心には 直接折曲軸とペダルが設置される。また中央骨体後端には車輪骨体が固定され、 その軸両端に二つの後輪が枢設され、中央骨体上部にはサドルが設置されて三輪 車となる。使用時、子供はサドルに座り、両足で折曲軸から延びたペダルを踏む 。すると前輪が回転し、車体が前方へ移動する。フロントフォークに設置された ハンドルには方向機能が備わり、車体の方向を制御する。 しかし、この種の三輪車構造は、基本構造が固定型で場所をとる。そのため折 り畳み式三輪車が作られたことがある。それはほとんどが長い骨体を湾曲する関 節になっており、折り畳んで車体の幅、長さを縮める。 Known infant bicycles have a tricycle structure because they are required to be stable. this There is a front fork in front of the center bone of the car body, and above the front fork Has a handle installed. In addition, front wheels are installed below, and at the center of the front wheel axle The bending shaft and pedal are installed directly. In addition, the wheel bone is fixed to the rear end of the central bone, Two rear wheels are pivotally installed at both ends of the shaft, and saddles are installed on the upper part of the central skeleton. Become a car. When using, the child sits on the saddle and presses the pedal extending from the bending axis with both feet. . Then, the front wheels rotate and the vehicle body moves forward. Installed on the front fork The steering wheel has a direction function to control the direction of the vehicle body. However, in this type of tricycle structure, the basic structure is fixed and takes up space. Therefore sometimes A folding tricycle has been made. It is a function of bending long bones. It becomes a knot and is folded to reduce the width and length of the car body.
