To provide a footstool which allows a worker to safely work without almost any danger of the footstool falling down even if the center of gravity of the worker who is on a top plate part of the footstool is biased forward.SOLUTION: In a footstool 1 which is configured such that an upper end of a front frame 7 having at least one tread 5 between a pair of right and left main legs 3a and an upper end of a rear frame 11 provided with at least one crossbar 9 between a pair of right and left main legs 3b are connected so that the lower ends of both of the frames are located apart from each other, a top plate part 15 is arranged near the connection part 13, and the lower portions of both of the main legs 3b of the rear frame 11 are provided with grounding portions 17 extending substantially horizontally so as to be located apart from the front main legs 3a. Handrail rods 21 projecting upward from the top plate 15 are provided at an upper end of the main legs 3a, respectively, of the front frame 7, and upper portions of the handrail rods 21 have bent portions 23 which are configured to approach each other.SELECTED DRAWING: Figure 1
【課題】踏台の天板部に上った作業者の重心が前方に偏ったとしても、踏台が転倒する危険が殆どなく、作業者が安全に作業できる踏台を提供する。【解決手段】 踏台１は、左右一対の主脚３ａの間に少なくとも一の踏桟５を備える前部フレーム７の上端と左右一対の主脚３ｂの間に少なくとも一の横杆９を備える後部フレーム１１の上端とを両フレームの下端が相互に離れるように連結する踏台において、該連結部１３の近傍に天板部１５を配設し、該後部フレーム１１の両主脚３ｂの下部は該前部主脚３ａから離れるように略水平に伸びる接地部１７を備えさせる。前部フレーム７の主脚３ａの上端部に前記天板部１５より上方に突出する手摺杆２１をそれぞれ設け、該該手摺杆２１の上部は、相互に接近するように屈曲部２３を有する。【選択図】図１
