ARROW MARK PLATE
To provide an arrow mark plate which is prevented from falling due to wind pressure, etc., with which installation time is shortened and safety of workers is improved, of which the board surface on which the arrow is displayed is not easily damaged, and which does not take much space for storage.SOLUTION: An arrow plate 100 has a rectangular display plate 10 with an arrow 1 displayed on the surface, a rectangular base plate 20 on which the display plate 10 is placed, and a support plate 30 that supports the display plate 10 from the back side, a locking part 21 is provided behind the front end of the upper surface of the base plate 20, one end of the support plate 30 is rotatably attached to the rear end of the base plate 20, the other end of the support plate 30 is rotatably attached to the back surface of the display plate 10. In the used state, the lower end part of the display plate 10 is fixed to the locking part 21, and the base plate 20 protrudes in front of the display plate 10. In the stored state, the display plate 10 and the support plate 30 are laminated on the upper surface of the base plate 20 with the display plate 10 on the lower side of the support plate 30 and the surface of the display plate 10 facing down.SELECTED DRAWING: Figure 1
【課題】風圧等による転倒を防止しながら設置時間を短縮して作業者の安全性を高めるとともに、矢印を表示した板面を痛めにくく、かつ収納時に嵩張らないようにした矢印板を提供する。【解決手段】表面に矢印１が表示された矩形状の表示板１０と、表示板１０を載置する矩形状のベース板２０と、表示板１０を裏面から支持する支持板３０とを有する矢印板１００であって、ベース板２０の上面の前端より後方に係止部２１が設けられており、支持板３０の一端がベース板２０の後端に回動可能に取り付けられ、支持板３０の他端が表示板１０の裏面に回動可能に取り付けられている。使用状態において、表示板１０の下端部が係止部２１に固定されて表示板１０の前方にベース板２０が突出する。収納状態において、表示板１０を支持板３０の下側とし表示板１０の表面を下向きとして、表示板１０及び支持板３０がベース板２０の上面に積層される。【選択図】図１
