Abstract
Abstract An inflatable member having an inflatable element which in some instances surrounds a body. The inflatable element is surrounded by a reinforcing sheath comprising longitudinally extending, circumferentially overlapping strips the ends of which are received in sleeves. A member is positioned adjacent the end of the strips and between the strips within the sleeves. The strips at each end including the members therebetween are secured together with an adhesive within the sleeves. Either or both ends of the inflatable element may be movable, and the movable end is provided with a void-forming medium or material to prevent the adhesive from filling a portion of the space adjacent the movable end and thereby provides a space to accommodate longitudinal movement of the end of the element by compressing or collapsing the material.
