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.

An inflatable toy, which when inflated has the contour of a hassock, which comprises an envelope, said envelope when inflated being substantially cylindrical with substantially circular and flat top and bottom walls and a substantially cylindrical side wall, said envelope being composed of soft limp flexibe non-resilient sheet material, said envelope having an opening in a wall thereof to enable the envelope to have air under mild pressure introduced into the interior thereof so as to inflate the same, means to selectively close said opening in the wall of the envelope in order to selectively retain air in the envelope and thereby keep the envelope inflated, a plurality of soft limp flexible planar vertical baffles mutually angularly spaced within said envelope, each of said baffles extending radially from near the central axis of said envelope and terminating short of the periphery of said envelope, rectilinear means attaching the top and bottom edges of each of said baffles to the circular top and bottom walls of said envelope, so that the top and bottom walls of said envelope, when said envelope is inflated, have a contour with a central outward bulge and discrete radial outward bulges between adjacent rectilinear attachment means, said baffles being tautened by outward force exerted on the top and bottom walls between the baffles by the pressure of the inflating air, said baffles being spaced from and free of attachment to the substantially cylindrical side wall of said envelope, so that the side wall of said envelope, when said envelope is inflated, has a horizontally outwardly bulging barrel-shaped contour, and at least one discrete solid object within said envelope, the inner edges of adjacent baffles being spaced apart when the envelope is inflated, said object being sized to pass between the inner edges of adjacent baffles to the central axis of said envelope.

An inflatable contoured article comprising:

(A) flexible wall means including a pair of end walls and an annular side wall connected intermediate the latter and having an inner circumferential surface, all of said walls bounding an interior compartment;
(B) means for inflating said flexible wall means from an initial collapsed configuration to an inflated configuration in which said annular side wall surrounds an axis of symmetry and in which the centers of said end walls are located at opposite axial ends of the symmetry axis;
(C) means for controlling the contour of said wall means by restricting relative separation of said end walls upon inflation, including
1. a plurality of flexible, taut, generally planar, baffle-type partitions located within said compartment and being equi-angularly spaced about the symmetry axis to thereby sub-divide said compartment into a corresponding plurality of sector-shaped chambers, each partition having
(a) an axially-extending inner edge spaced radially from the symmetry axis at a predetermined radial distance,
(b) an axially-extending outer edge spaced radially from the symmetry axis at a radial distance greater than said predetermined distance,
(c) a radially-extending upper edge connected to one of said end walls, and
(d) a radially-extending lower edge connected to the other of said end walls,
2. all of said inner edges of the partitions terminating at the end walls at inner annuli which have a radius equal to said predetermined radial distance and which surround the symmetry axis, and thereby forming upon inflation each end wall with a central, generally circular outwardly-bulging portion which is free from constraint by said partitions,
3. all of said outer edges of the partitions terminating at the end walls at outer annuli which have a radius equal to said greater radial distance and which are concentric with the inner annuli,
4. all of said radially-extending upper and lower edges of the partitions terminating at the end walls along seams which extend radially relative to the symmetry axis and thereby forming upon inflation each end wall with outwardly-bulging generally sector-shaped portions which are free from constraint by said partitions,
5. said outwardly-bulging central circular portion and said sector-shaped portions on each end wall together resembling a hassock seat upon inflation,
6. each two inner edges of each two adjacent partitions being spaced circumferentially apart of each other by a predetermined spacing, and
7. each outer edge of the partitions being spaced radially from said inner circumferential surface of said side wall by a preselected spacing;
and
(D) means for impacting against said wall means in the inflated configuration to thereby provide entertainment reward for a child, including
(1.) a plurality of movable amusement-type toy objects within said interior compartment, each toy object having a cross-sectional dimension which is smaller than said predetermined spacing to thereby permit passage through the latter of at least one toy object into any one of said chambers, and which is larger than said preselected spacing to thereby bar passage through the latter of the toy objects from one chamber to another.
