MOVABLE HANDRAIL OF PROTECTIVE FENCE
PROBLEM TO BE SOLVED: To provide a highly safe movable handrail of a protective fence that does not require a tool for removal, and facilitates fitting and removal without a concern over the handrail being readily dislocated after fitting.SOLUTION: An insertion part 51 of a movable handrail 50 is inserted into two support holes 13h, 23h from outside, so that a large diameter part 52a is spanned to reach close to support brackets 13, 23. An engaging piece 52b is protruded on an outer periphery of the large diameter part 52a of the movable handrail 50 and engaging notches 13c, 23c are formed on the support brackets 13, 23, to rotate the movable handrail 50 around an axis in the direction of insertion. Then, the engaging piece 52b is inserted into the engaging notches 13c, 23c at a prescribed angle to restrict movement of the movable handrail 50 in the direction of insertion, and a compression spring 53 presses the engaging piece 52b toward an outer periphery of the engaging notches 13c, 23c, to stop rotation of the engaging piece 52b.SELECTED DRAWING: Figure 1
【課題】 取り外しに工具が必要なく、脱着が容易だが取り付けたときは容易に外れるおそれが無く、安全性の高い養生柵の可動手摺を提供する。【解決手段】 可動手摺50の挿通部51を２つの支持孔13h,23hに外方から挿通させ、大径部52aが支持ブラケット13,23付近まで達するように架け渡したときに、可動手摺50の大径部52aの外周に係合片52bを突設し、支持ブラケット13,23に係合切欠13c,23cを設け、可動手摺50を挿通方向を軸として回転させたときに、所定の角度で係合片52bが係合切欠13c,23cに挿入され、可動手摺50が挿通方向に移動不能に制限されるとともに、圧縮バネ53が係合片52bを係合切欠13c,23c外周に向けて押圧し、係合片52bの回転止めとした。【選択図】図１
