Description

本発明は、自転車用幼児座席に関するものである。   The present invention relates to an infant seat for bicycles.

自転車用幼児座席には、座部と左右一対の座席側壁とを有し、左右一対の座席側壁間に幼児座席に座った幼児が握るためのハンドルを設けたものがある。
この種の従来の自転車用幼児座席には、ハンドルの両端部を左右一対の座席側壁に対して横軸廻りに揺動調整自在に取り付け、これにより幼児座席に座った幼児の着座姿勢に応じてハンドルを前後に横軸廻りに揺動調整して、幼児座席に座った幼児がハンドルを楽に握ることができるようにしたものがある(例えば特許文献1)。
Some bicycle infant seats have a seat portion and a pair of left and right seat side walls, and a handle is provided between the pair of left and right seat side walls for an infant sitting on the infant seat.
In this kind of conventional bicycle infant seat, both ends of the handle are attached to the left and right pair of seat side walls so as to be swingable around the horizontal axis, thereby depending on the sitting posture of the infant sitting on the infant seat. There is one in which an infant sitting on an infant seat can grip the handle comfortably by swinging the handle back and forth around the horizontal axis (for example, Patent Document 1).

特許第3840657号公報Japanese Patent No. 3840657

しかし、従来では、ハンドルの揺動調整によるハンドルの前後方向への移動調整範囲は僅かであって、移動調整の段数も少なかった。このため、幼児は成長が早く伸長等が伸びる割合も大きいため、ハンドルの背凭れ部からの離間幅を小さな幼児用に設定しておけば、幼児が成長するつれてハンドルの位置が背凭れ部に近すぎるようになり、短期間でハンドルを良好に握れなくなるし、ハンドルが邪魔になることもあった。
本発明は上記問題点に鑑みて、幼児座席に座る幼児が小さいときから長期間に亘ってハンドルを良好に握ることができるようにしたものである。
However, conventionally, the range of movement adjustment of the handle in the front-rear direction by adjusting the swing of the handle is small, and the number of stages of movement adjustment is small. For this reason, since infants grow faster and the rate of extension etc. grows larger, if the distance from the backrest part of the handle is set for small infants, the position of the handle will change as the infant grows. It became too close to the handle, and the handle could not be gripped well in a short period of time, and the handle sometimes became an obstacle.
In view of the above problems, the present invention is capable of satisfactorily grasping the handle for a long period of time from when the infant sitting in the infant seat is small.

この技術的課題を解決する本発明の技術的手段は、座部と左右一対の座席側壁とを有し、左右一対の座席側壁間にハンドルが設けられた自転車用幼児座席において、
