PROBLEM TO BE SOLVED: To constitute a leg body so that legs can be simply, easily and compactly closed, for securing safety of work in use, on a stepladder type workbench for installing a floor top plate in a freely opening-closing leg body, and forming a work space of an extension column part of the leg body extended above the floor top plate.SOLUTION: A first leg body (2) and a second leg body (3) having respectively columns on the left-right, are connected by pivotal joining means (4) of a biaxial form for constituting first pivotal joining means (11) and second pivotal joining means (12) in a mutually separated state, and are constituted so as to close legs up to becoming a parallel state by approaching both leg bodies (2) and (3) when lifting the first leg body (2) from a leg opening state, extension column parts (2b) and (3b) of both leg bodies for forming a work space are mutually connected-supported by brace means (25), and the brace means is expanded in a straight line shape in the leg opening state, and is constituted so as to fold up the brace means upward in a leg closing state.SELECTED DRAWING: Figure 9
【課題】開閉自在な脚体に床天板を架設すると共に、該床天板の上方に延長した脚体の延長柱部により作業空間を形成した脚立式作業台に関して、使用時における作業の安全を確保すると共に、脚体を簡単容易かつコンパクトに閉脚できるように構成する。【解決手段】それぞれ左右に支柱を備えた第１脚体(2)と第２脚体(3)を相互に離間させた状態で、第１枢結手段(11)と第２枢結手段(12)を構成する２軸形式の枢結手段(4)により連結し、開脚状態から第１脚体(2)を持ち上げたとき、両脚体(2)(3)を近接させ平行状態となるまで閉脚するように構成しており、前記作業空間を形成する両脚体の延長支柱部(2b)(3b)を相互にブレイス手段(25)により連結支持しており、開脚状態でブレイス手段を直線状に展開し、閉脚状態でブレイス手段を上向きに折畳むように構成している。【選択図】図９
