发明名称 Roof safety system
摘要 A lightweight roof safety system with a top portion and a bottom portion is easily carried to flat rooftop of a building and assembled to form a rigid structure that has a connection member for attaching one or more safety lines. The top portion has a central member to which three or more legs are removably attached. The bottom portion has three or more base members that correspond to the leg members and a pair of leg members attached to distal and proximal ends of a base member to form a rigid structure. Each of the base members is weighted by hand weights placed in weight containers to prevent tipping of the roof safety system. The base members are, optionally, provided with support members that rest on a flat rooftop providing to improve stability of the roof support system.
