ABSTRACT:
A self-erecting floatable structure which includes a collapsible extendible element and a hollow substantially cylindrical shaped core member about which the collapsible extendible element can be wound and an inflatable torus that is connected to the collapsible extendible element. The hollow cylindrical shaped core member is configured so as to readily receive the collapsed torus and two gas generating members are connected to the torus which generates gas to inflate the torus when they come into contact with water. Provisions are made for maintaining the torus and the collapsible extendible element in a compact configuration with the cylindrical shaped core member until the self-erecting floatable structure comes into contact with water. Upon contact with water the self-erecting floatable structure erects itself in the water so that the inflated torus and the core member which acts as a weight maintain the upper portion of the extendible element in a substantially upright position.
