FOLDABLE STEPS
To provide foldable steps, in which load on treads and links is reduced, breakage of hinges is prevented, deformation of the treads is prevented, and stability is ensured.SOLUTION: The foldable steps are provided with: a plurality of treads 21 to 25 having a shorter direction X and a longer direction Y; front longer shafts 31 to 35 respectively arranged in the longer direction Y at rear ends of the treads 21 to 25; rear longer shafts 41 to 45 respectively arranged in the longer direction at rear ends of the treads 21 to 25; shorter shafts 51 to 55 respectively arranged in the shorter direction of the treads 21 to 25; outer pair links 6 which are arranged both ends of the treads 21 to 25 and protrude in the shorter direction X; and one or more inner links 7 which are arranged at middle section of the treads 21 to 25 and protrude in the shorter direction X.SELECTED DRAWING: Figure 1
【課題】踏板やリンクへの負荷の軽減、ヒンジの破損防止、踏板の変形防止、安定性を確保する折畳式ステップを提供する。【解決手段】短手方向Ｘと長手方向Ｙを有する、複数の踏板２１〜２５、踏板２１〜２５の前端部の長手方向Ｙにそれぞれ設けられる前側長手軸３１〜３５、踏板２１〜２５の後端部の長手方向にそれぞれ設けられる後側長手軸４１〜４５、踏板２１〜２５の短手方向にそれぞれ設けられる短手軸５１〜５５、踏板２１〜２５の両側部に設けられ、短手方向Ｘに延び出す一対の外側リンク６、踏板２１〜２５の中間部に設けられ、短手方向Ｘに延び出す１つ以上の内側リンク７、を備える。【選択図】図１
