发明名称 Hinged supported roof scaffold
摘要 A support member for roof scaffolding having a base plate that is designed to be secured to a roof deck. The base plate is operably connected to a hinged plate that carries on it a sleeve that is used to engage scaffolding. Because of the way the hinged plate is mounted onto the base plate, a wedged end plate is formed to allow the base plate to easily slip underneath a shingle on a roof. Furthermore, because of the hinged plate the scaffolding is able to be maintained at a right angle to the ground.
