A ball toy having a solid, resiliently flexible body is disclosed. The body is penetrated by a bore, wherein hearing means are mounted, defining a rotational axis of the body therein. The bore has a bore closure at each end, mechanical connection means connecting each closure to the bearing means. The body is able to spin on said axis relative to the closures, when the closures are held in a pinching manner by a user. The body is made of a thermoplastic rubber of selected hardness properties, giving it excellent bouncing performance, with unpredictability of bouncing direction resulting from the spinning of the body.

A tumbling toy system where a tumble pin tumbles in a guide track. The guide track has two sides and a bottom. The two sides are a first distance apart at a first elevation height. Each tumble pin rests in the guide track and is free to tumble end-over-end. As the tumble pin tumbles, the ends of the tumble pin cyclically contact the bottom of the guide track. Each tumble pin tapers from a maximum diameter at its midplane to a minimum diameter at either end. The maximum diameter of the tumble pin is larger than the distance between the two sides of the guide track. This causes the tumble pin to cyclically contact the two sides of the guide track as it tumbles. When the tumble pin contacts the sides of the guide track, the tumble pin becomes temporarily suspended between the two sides and tumbles in place.

A wobbling toy is configured to spontaneously re-orient itself in an upright position solely under the force of gravity. The self-righting toy includes a weight that is confined to and movable along a pathway such that the weight defines a dynamic mass that is sufficient to cause the housing to spontaneously pivot along a convex outer surface profile in coordination with a position of the weight in the pathway. The self-righting toy is configured to maintain a positional relationship of the weight so that the housing is spontaneously pivotable along the convex surface without external force supplied by a user.

A rolling toy to be rolled on a horizontal support surface, for instance, on a floor, having a primary roller and a secondary roller. The primary roller having a tubular-like member extending along a longitudinal axis and at least one annular flange fixedly attached to the tubular-like member and extending outwardly therefrom. The secondary roller is adapted a for rolling motion upon an interior surface of the tubular-like member when the primary roller rotates about the longitudinal axis due to the rolling motion of the rolling toy on the horizontal support surface. At least one of the following includes a helical guiding means: (i) the tubular-like member and (ii) the secondary roller. Thereby, when the secondary roller is disposed on the interior surface of the tubular-like member and the primary roller is set in a rolling motion on the horizontal support surface in a predetermined direction, the rolling motion of the primary roller results in a tilting of the latter. The tilting of the primary roller may result in its standing vertically on the horizontal support surface.

A rolling toy assembly that has a hollow body. The hollow body has an interior and a bottom surface with an open window that accesses the interior. A spherical mass is disposed within the interior of the hollow body. The spherical mass is too large to pass completely through the open window. An eccentric weight is coupled to the hollow body. The eccentric weight biases the hollow body into a tilted position wherein the bottom surface and the window are tilted at an angle of inclination. This enables the toy assembly to roll over small obstacles. A play platform is provided. The play platform has a top surface that defines at least one concavity. The concavity is surrounded by a peripheral rim bump. The toy assembly is placed on the play platform and is caused to roll by manually manipulating the play platform.
