Abstract
A molded rubber toy is formed with a hemispherical base, a shaft extending upwardly from the base, a spoke-like array of arms extending from the shaft and a bumper formed on the top end of the shaft The arms limit the tipping movement of the base, and the base is heavier than the combined weights of the shaft, arms and bumper so that the weight of the base rolls the toy back onto the center of its spherical base surface and into an upright position when the toy is upset from its upright at-rest position.
Claims8
A chewable, resilient self-righting pet toy, comprising:
- a hemispherical base having a radius and an upper surface;
- said upper surface having a plurality of radially extending, symmetrically spaced-apart ribs disposed thereon;
- a shaft extending upwardly from said upper surface of said base;
- and
- a plurality of arms having ends and extending radially outwardly from said shaft;
- whereas said toy has a center of gravity below said upper surface portion so that the toy will resist tipping over.
A chewable, resilient self-righting pet toy, comprising:
- a base having a curved bottom portion, an upper surface and a plurality of ribs provided on said upper surface, said ribs being symmetrically spaced apart on said upper surface;
- a shaft extending from said base;
- and
- a plurality of arms extending outwardly from said shaft,
- wherein said toy is a homogeneous, one-piece molding formed from a resilient, chewable material and
- wherein said base provides a restorative uprighting force by having the weight of the toy concentrated in said base.
