Abstract
An inflatable article having an inflatable envelope made of a gas impervious material which is at least in part resilient forming a closed surface and provided with at least one inflating valve thereon. At least one hollow protrusion, provided with a closed end and an open end, is attached to the envelope, and at least one movable internal object is contained within the closed surface. One or more restraining elements may be provided on the outer surface of the envelope to keep the inflatable envelope in a restrained condition during use. An internal supporting element, at least in part rigid, is attached to the wall of the closed surface. The inflatable article further includes a control element connected with the closed end of the hollow protrusion and extending externally of the closed surface, and at least one movement imparting element movably mounted on the internal supporting element and associated with the closed end of the hollow protrusion for imparting movement to the internal object when activated by the external control element. Furthermore, within the envelope at least one returning element is associated with the hollow protrusion for returning the hollow protrusion to its original unflexed position after the external force applied by a user for activating the external control element is released.
