Abstract

Abstract An inflatable toy which when inflated has the contour of a hassock. The toy features a cylindrical envelope and inner radially-extending planar baffles, these elements being composed of soft limp flexible material such as a thermoplastic plastic. When the toy is inflated by introducing air under mild pressure into the envelope, the top and bottom walls of the envelope are distended so as to assume the contour of the top and bottom of a hassock, i.e. with a central bulge and discrete radial outward bulges. This configuration is formed by disposing the baffles vertically and mutually angularly spaced, each of the baffles extending radially from near the central axis of the envelope and terminating short of the periphery of the envelope, with rectilinear attachments of the top and bottom edges of each of the baffles to the top and bottom walls of the envelope. The baffles are tautened by outward force exerted on the top and bottom walls between the baffles, by the pressure of the inflating air. The baffles are spaced from and free of attachment to the cylindrical side wall of the envelope, so that the side wall assumes a horizontally outwardly bulging barrel-shaped contour when the envelope is inflated. The inner edges of adjacent baffles are spaced apart when the envelope is inflated. At least one discrete solid object is disposed inside the envelope, the object being sized to pass between the inner edges of adjacent baffles to the central axis of the envelope.
