发明名称 Scaffold safety pin
摘要 A scaffold is disclosed having a platform and at least a pair of generally horizontally extending, spaced support members beneath the platform. A pair of longitudinally spaced openings are formed in the platform through one surface to extend generally perpendicular thereto. A hollow cylinder is mounted in each opening having a pin mounted therein for movements between a retracted position and an extended, operative position. The platform can be disposed on the support members with the pins in the operative positions to prevent the platform from sliding off the support members, and the platform can be turned over to move the pins to the retracted positions for transport and storage purposes.
