SAFETY FENCE
To provide a safety fence which has a simple configuration, which can be easily assembled, which has stability in installing, and which is easily transported.SOLUTION: A safety fence includes: a fence body 20 which has a plurality of leg portions 22 and in which a pantograph mechanism 24 between the leg portions 22 extends in a bellows shape to surround an opening; a lower reinforcement frame 30 fixing the leg portion 22 of the fance body 20 expanded in a fence shape surrounding the opening; and an upper reinforcement bar 40 fixed so as to cross an upper horizontal member 26 of the fence body 20 expanded in a fence shape surrounding the opening. The upper reinforcement bar 40 and the lower reinforcement frame 30 have a folded structure in which a plurality of rod-like members are connected so as to be folded. There is provided a joint structure in which end portions of the plurality of rod-like members are made to cross each other and to be connected with each other, at the end portions.SELECTED DRAWING: Figure 1
【課題】簡易な構造で組立てが容易で設置時に安定性があり、持ち運びも容易な安全柵を提供する。【解決手段】複数の脚部２２を有し、前記脚部２２間のパンタグラフ機構２４が蛇腹状に伸長して開口部を囲む柵本体２０と、前記開口部を囲む柵状に広げた前記柵本体２０の脚部２２を固定する下部補強枠３０と、前記開口部を囲む柵状に広げた前記柵本体２０の上部横架材２６と交差するように固定する上部補強バー４０と、を有し、前記上部補強バー４０及び前記下部補強枠３０は、複数の棒状部材を折り畳み可能に連結した折り畳み構造であり、複数の棒状部材を連結した端部どうしを交差させて連結する仕口構造を前記端部に設けた。【選択図】図１
