FUNNEL-SHAPED PROTECTIVE SHELF DEVICE FOR TEMPORARY SCAFFOLD
To provide a funnel-shaped protective shelf device for temporary scaffold which has no risk of a rear end part of a support member unexpectedly coming off from a holding member, and which can make the holding member more compact.SOLUTION: In a funnel-shaped protective shelf device 1 for temporary scaffold, a front end part of a support member 8 is rotatably connected to the intermediate part of length of a vertical frame member 3 constituting part of a square frame 6 in which a mesh sheet 7 is stretched and fixed, and a rear end part of the support member is held by a holding member 9 mounted on a support pillar S1. At the rear end part of the support member, an engaging pin 11 having a shaft part 111 and a head part 112 is mounted in a protrusive manner. On a holding wall part 911 of the holding member, a guide groove 12 extending vertically and locking grooves 13A, 13B, 13C, 13D extending frontward from a plurality of height positions of the guide groove are formed. At the height position corresponding to substantially the width center of an opening of each locking groove excluding the lowermost locking groove on a guide groove rear side edge of the holding wall part, a protrusion 16 for locking pin coming-off prevention is formed.SELECTED DRAWING: Figure 3
【課題】支持部材の後端部が保持部材から不用意に外れるおそれがない上、保持部材をよりコンパクトにすることができる仮設足場用朝顔装置を提供する。【解決手段】仮設足場用朝顔装置1は、メッシュシート7が張り止められる方形枠6の一部を構成する縦枠部材3の長さ中間部に支持部材8の前端部が回動自在に連結され、支柱S1に取り付けられた保持部材9によって支持部材の後端部が保持されている。支持部材の後端部に、軸部111および頭部112を有する係合ピン11が突出状に取り付けられている。保持部材の保持壁部911に、上下方向にのびる案内溝12と、案内溝の複数の高さ位置から前方にのびた係止溝13A,13B,13C,13Dとが形成されている。保持壁部の案内溝後側縁における最下位の係止溝を除いた各係止溝の開口のほぼ幅中央に対応する高さ位置に、係止ピン脱落防止用突起16が形成されている。【選択図】図３
