Abstract

A toy having a motorized portion in the form of an inanimate object and a non-motorized portion in the form of an animate object. The two portions are tethered together, and the motorized portion is driven such that the non-motorized portion in the form of an animate object appears to be alive and in pursuit of the inanimate motorized portion. The motorized portion preferably is in the form of a substantially spherical hollow ball within which an eccentric driving mechanism is placed. The non-motorized portion is an animal with a furry body or bushy tail and is preferably a weasel, embodies by a furry tail having a face invisibly connected to the ball. The non-motorized portion is preferably tethered to the motorized portion with a substantially invisible attachment so that from a distance the two portions of the toy do not appear to be connected together.

15. A toy as in claim 14, wherein said tether is substantially invisible.

16. A toy as in claim 14, wherein said flexible, non-motorized element is in the shape of an animal and said motorized element is in the shape of a ball.

17. A toy as in claim 14, further comprising a switch for actuating said driving mechanism.

18. A two part toy comprising:

a motorized portion containing a motor;

a non-motorized portion spaced apart from said motorized portion; and

a substantially invisible, clear flexible tether having a first end connected to said motorized portion through an aperture in said motorized portion and a second end coupled to an attachment point on a head portion of said non-motorized portion to thereby connect said non-motorized portion to said motorized portion so that the entirety of said non-motorized portion can move freely in three dimensions around the attachment point on said motorized portion and such that a portion of the tether is movable into and out of the aperture;

whereby said non-motorized portion is connected to said motorized portion such that said non-motorized portion appears to chase after and propel said motorized portion when said motor is operating.

19. A toy as in claim 18, wherein said non-motorized portion is in the form of an animate object and said motorized portion is in the form of an inanimate object.

20. A toy as in claim 19, wherein said motorized portion is a ball containing an eccentric motor, said non-motorized portion being attached to said motorized portion to appear to chase after and roll with said ball.

21. A toy comprising:

a motorized portion having a driving mechanism;

a furry element spaced apart from said motorized portion and resembling at least a part of a live animal; and

a flexible tether connecting said furry element to said motorized portion, said tether connected to said motorized portion through an aperture in said motorized portion, a portion of said tether is movable into and out of said aperture, and the entirety of said furry element having the ability to move freely in all dimensions about an attachment point on said motorized portion;

whereby when said driving mechanism is activated said furry element moves with said motorized portion to simulate a live animal chasing after and propelling said motorized portion so that said motorized portion appears to be propelled by an animal embodied by said furry element.

22. A toy as in claim 21, wherein said motorized portion is a freely rotatable ball and said furry non-motorized element is at least rotatable about a radius of said ball.

23. A toy as in claim 21, wherein said furry element has a nose and said tether connects said nose of said furry non-motorized element to said motorized portion.
