发明名称 Flexible ladder with supporting accessory
摘要 A rope ladder with support attachments is presented. The invention includes a hook, allowing the invention to be hung from a building, a rope ladder body, comprising a pair of belt rails and multiple rungs disposed between the belt rails attached to the hook, and support attachments symmetrically fixed onto the inside surface of the belt rails at joints between rails and rungs. Each support attachment is of a folding design with torsion spring so that the support attachment automatically opens outward until the inner angle between the support attachment and rung is slightly larger than 90 degrees. Support attachments provide a gap between belt rails and the wall of a building. The present invention ensures a suitable gap between rungs disposed along the length of the rope ladder and building wall so as to allow the user to easily, reliably and properly step onto each rung of the rope ladder.
