  • Patent number: 4232477
    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.
