Abstract
Abstract These magnetic kinetic amusement devices have plural magnetically coupled elements that exhibit intermittent, alternating motion as energy is interchanged between the elements. In one embodiment, plural vertically spaced arms are mounted for pivotal motion about a common vertical axis. Each arm has a pair of magnets at its extremities. As it rotates through a partial revolution, its kinetic energy is magnetically coupled to an adjacent arm. As a result, adjacent arms alternately rotate through fractional revolutions, providing quantized motion that is fascinating to watch. In other embodiments the magnetically coupled elements comprise pendulums each having at the pendulum end a design member containing a magnet. The plural pendulums may be disposed in three dimensional array, or may be suspended from a common support with the magnets aligned for mutual repulsion so that the pendulums assume a conical arrangement. Displacement or rotation of any pendulum design member causes energy exchange through magnetic coupling, resulting in an eye-appealing intermittently alternating motion of all design members.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
173 words
A magnetic kinetic amusement device comprising: a frame, at least three magnetic elements, at least three mounting means supported by said frame, at least one magnetic element being mounted by each such means, said magnetic elements each having the same type of pole facing upwardly as each other magnetic element, said magnetic elements thus being supported in spaced, magnetically coupled relationship so that motion of one mounting means intermittently is interchanged magnetically with another such mounting means to produce intermittent alternating motion of the magnetically coupled means, and wherein each mounting means comprises a design member situated at the bottom of an individual string, a magnetic element being attached to each such design member, each string being attached to a location on said frame spaced from the location of attachment to the frame of each other string with said locations being spaced apart in more than one dimensional plane so that said design members are spatially distributed in three-dimensional array, each string permitting both swinging and rotational motion of the attached design member.
Claim 2
Dependent Claim
173 words
A magnetic kinetic amusement device comprising: a frame, at least three magnetic elements, at least three mounting means supported by said frame, at least one magnetic element being mounted by each such means, said magnetic elements each having the same type of pole facing upwardly as each other magnetic element, said magnetic elements thus being supported in spaced, magnetically coupled relationship so that motion of one mounting means intermittently is interchanged magnetically with another such mounting means to produce intermittent alternating motion of the magnetically coupled means, and wherein each mounting means comprises a design member situated at the bottom of an individual string, a magnetic element being attached to each such design member, each string being attached to a location on said frame spaced from the location of attachment to the frame of each other string with said locations being spaced apart in more than one dimensional plane so that said design members are spatially distributed in three-dimensional array, each string permitting both swinging and rotational motion of the attached design member.
Claim 3
Dependent Claim
21 words
A device according to claim 1 together with means for imparting motion to at least one of said mounted magnetic elements.
Claim 4
Dependent Claim
206 words
A magnetic kinetic amusement device comprising: a frame, at least three magnetic elements, at least three of mounting means supported by said frame, at least one magnetic element being mounted by each such means, said magnetic elements thus being supported in spaced, magnetically coupled relationship so that motion of one mounting means intermittently is interchanged magnetically with another such mounting means to produce intermittent alternating motion of the magnetically coupled means, wherein said mounting means comprises at least three pendulums suspended from a common support portion of said frame, said pendulums being spaced apart in more than one dimensional plane, each pendulum further having a design member at its lower end, each design member being provided with one of said magnetic elements, said magnetic elements being poled so that each magnetic element has the same type of pole facing upwardly as each other magnetic element, whereby said pendulums are magnetically repelled into conical alignment, displacement or rotation of any design member being intermittently, magnetically coupled to cause intermittent, alternating motion of adjacent pendulums, and wherein the magnetic element of each pendulum comprises a thin bar magnet generally aligned with the pendulum support axis, the bar magnets for all of said pendulums being mounted for mutual repulsion.
