SLIP PREVENTION TOOL FOR LADDER, AND LADDER
PROBLEM TO BE SOLVED: To provide a slip prevention tool for a ladder and a ladder that may be held stably on a roof side.SOLUTION: A slip prevention tool for a ladder includes a base member 2, a fulcrum pin 3 provided on the base member 2, a load transmission member 4 provided rotatably on the fulcrum pin 3, and pressing members 5, 5 provided on the load transmission member 4. The base member 2 has a base plate part 21 fixed on a support post 101. The fulcrum pin 3 is provided on a central part in a width direction of the base plate part 21. The load transmission member 4 has a flat plate part 41 rotatable around the fulcrum pin 3. Each pressing member 5 has a support member 6 provided on both sides of the fulcrum pin 3 on the flat plate part 41, a shoe member 7 provided on each support member 6, and a coil spring (energizing member) 8 that provides elastic force to each shoe member 7. Each support member 6 has a swinging support shaft 64, each shoe member 7 is connected rotatably with each swinging support shaft 64, and each coil spring 8 provides the elastic force to move a tip part of each shoe member 7 downward.SELECTED DRAWING: Figure 1
【課題】屋根の側で安定的に保持することができる梯子用滑り防止具及び梯子を提供することを課題とする。【解決手段】基礎部材２と、基礎部材２に設けた支点ピン３と、支点ピン３に回動自在に設けた荷重伝達部材４と、荷重伝達部材４に設けた押圧部材５、５とを備え、基礎部材２は支柱１０１に固定する基板部２１を有し、支点ピン３は基板部２１の幅方向の中央部に設け、荷重伝達部材４は支点ピン３の回りに回動自在な平板部４１を有し、各押圧部材５は平板部４１の支点ピン３の両側に設けた支持部材６と、各支持部材６に設けたシュー部材７と、各シュー部材７に弾性力を付与するコイルスプリング（付勢部材）８とを備えており、各支持部材６は揺動支持軸６４を有し、各シュー部材７は各揺動支持軸６４に回動自在に連結され、各コイルスプリング８は各シュー部材７に先端部が下方に向かう方向の弾性力を付与するように構成されている。【選択図】図１
