To solve a problem in that, in a snowy country, a foot path is not often ensured, people, therefore, wait for gradual widening of a road width along footsteps left by someone else, in addition, a three-wheel type baby carriage with large wheels is also vulnerable to snow coverage and cannot be moved along such footsteps, in addition, the use of a baby carriage in train is often disapproval in Japan, which requires a solution, meanwhile an auxiliary wheel for an infant bicycle is of fixed type, which is not easy for an infant to practice riding without the auxiliary wheel, and a bicycle that can be folded/unfolded is also proposed but is not widely spread, and, therefore, to develop a highly safe auxiliary wheel mechanism, and generalize it as a baby carriage component, thereby reducing a manufacturing cost for development and enabling feedback for a bicycle.SOLUTION: The invention comprises (1) setting up a two-wheel type baby carriage such that it can be passed on a snowy road, (2) developing a highly safe auxiliary wheel for stabilizing the two-wheel type baby carriage, and (3) minimizing an occupied floor area so as to prevent inconvenience in riding on/off a train and a bus.SELECTED DRAWING: Figure 1
【課題】 雪国では、歩道が確保されないことが多く、通常は、誰かが残した踏み跡に沿って、次第に道幅が広がって行くのを待つ。車輪の大きな3輪型のベビーカーも、積雪には弱く、踏み跡を通ることができない。また、日本国内では電車内でのベビーカー使用に対し厳しい意見があり、解決策が待たれていた。一方、幼児用の自転車の補助輪は一般に固定式で、補助輪をはずして練習するには決意が要る。格納・展開が可能なものも提案されているが、普及には至っていない。そこで、安全性の高い補助輪機構を開発し、ベビーカー用部品として普及させることにより、開発製造コストを下げ、自転車にフィードバックできる可能性がある。【解決手段】(1)雪道を通行できる二輪型のベビーカーを成立させる(2)二輪型ベビーカーを安定させるための、安全性の高い補助輪を開発する(3)電車やバスへの乗降に不便を来たさないよう、占有床面積を最小化する【選択図】図1
