Abstract
Abstract A toy consisting of a base with an aperture across which is tightly stretched a string or wire. A simulated animal has notches in its rear hooves supportingly engaged in the string or wire. The front hooves of the animal consist of permanent magnets and the base has mounted thereon subjacent said front hooves a permanent magnet of a polarity which opposes the polarity of the magnets forming the front hooves of the simulated animal. Thus, when the animal is initially pivoted on the stretched string or wire and then released, the opposing magnets produce a spring bouncing effect which causes the simulated animal to rock or oscillate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
A toy comprising a supporting base, a simulated animal, means pivotally mounting one portion of the simulated animal on the base for rotation around a fixed transverse axis substantially coplanar with the base, a first permanent magnet fixedly mounted on the base subjacent a second portion of the simulated animal spaced from said one portion, and a second permanent magnet mounted on said second portion and being poled so as to be repelled by the first magnet, whereby the repulsion between the magnets provides a spring action between the base and the simulated animal when the simulated animal rotates, enabling the simulated animal to oscillate up and down around said transverse axis.
Claim 2
Dependent Claim
112 words
A toy comprising a supporting base, a simulated animal, means pivotally mounting one portion of the simulated animal on the base for rotation around a fixed transverse axis substantially coplanar with the base, a first permanent magnet fixedly mounted on the base subjacent a second portion of the simulated animal spaced from said one portion, and a second permanent magnet mounted on said second portion and being poled so as to be repelled by the first magnet, whereby the repulsion between the magnets provides a spring action between the base and the simulated animal when the simulated animal rotates, enabling the simulated animal to oscillate up and down around said transverse axis.
Claim 3
Dependent Claim
27 words
The toy of claim 1 and wherein the simulated animal has rear legs and front legs and the pivotal mounting means is located at said rear legs.
Claim 4
Dependent Claim
16 words
The toy of claim 1, and wherein the second magnet is mounted on said front legs.
Claim 5
Dependent Claim
18 words
The toy of claim 3 and wherein said second magnet comprises a simulated hoof of a front leg.
Claim 6
Dependent Claim
17 words
The toy of claim 4, and wherein said second magnet comprises resilient material containing permanently magnetized particles.
Claim 7
Dependent Claim
51 words
The toy of claim 2, and wherein said supporting base is formed with an aperture subjacent the rear legs of said simulated animal and said pivotal mounting means comprises a transverse bridging member secured across said aperture, said rear legs having bottom notches pivotally receiving and frictionally engaging said transverse member.
Claim 8
Dependent Claim
16 words
The toy of claim 6, and wherein said transverse bridging member comprises a taut filamentary element.
Claim 9
Dependent Claim
19 words
The toy of claim 7, and wherein said base has a recess in which said first magnet is received.
Claim 10
Dependent Claim
20 words
The toy of claim 8, and wherein said recess has a relatively thin top wall portion covering said first magnet.
Claim 11
Dependent Claim
58 words
The toy of claim 2, and wherein said magnets comprise respective permanent magnets, one being mounted in the base and the other being mounted on the lower end of a front leg of the simulated animal and located above said one permanent magnet, the permanent magnets having poles of like polarity facing each other to provide repulsion therebetween.
