Abstract: A material joint connecting an internal spar or baffle to panel walls of inflatable structures. The material joint is formed by a folded center strip and a pair of side strips. The side edges of the center strip are folded to form an initial “T-shaped” cross-section having a middle section, two side sections formed by a first bend, and two overlapping end sections formed by a second bend. The middle section is fused directly to the facing surface of the panel wall and the overlapping end sections are fused together to extend perpendicularly from the middle section. The end strips overlap the center strip with part of the end strips fused to the side sections of the center strip and part fused directly to the panel wall. The spar or baffle is connected to the fused overlapping end sections of the center strip.

Abstract: A parachute-type amusement device including an outer section extending around at least a portion of the device to provide a hand graspable handle, and an inner section having a sheet of flexible material capable of billowing with air upon manipulation of the device. The handle permits easy folding of the device for compact storage, e.g., in a bag or pouch. In one embodiment, the outer section has multiple handle members, such as foam inserts. In another embodiment, there is a single flexible handle member, such as a rope, cord, braid, and/or a tubular foam insert. The handle members may be spaced from one another within the outer section to facilitate grasping and/or folding of the device. The sheet may be circular, rectangular, etc., and may be visually divided into a multiple discrete segments, e.g. by coloration. A discrete number of foam inserts may be positioned within each of segment.
