Abstract
Abstract A track system includes an accelerator track section having a ferrous metal accelerator rod which attracts a magnetized spinning top and imparts a linear acceleration to the top. Additional coaster and turn track sections provide a selected glide path for the freely moving top. Alternate embodiments of the accelerator track sections include the incorporation of a guide channel, a "T" shaped accelerator strip, a planar accelerator strip, and a dual sided accelerator strip.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
A dynamic toy apparatus utilizing kinetic rotary energy of a spinning top for conversion to translatory motion comprising a top having a stem and a body portion, stationary guidance means having a runway for supporting the spinning top on one end of the stem in a substantially vertical orientation, the guidance means further having acceleration means including an elongated member mounted within said runway, said member being adapted for providing a contact surface for said end of the stem and for magnetically interacting therewith to impart a linear velocity to the top.
Claim 2
Dependent Claim
92 words
A dynamic toy apparatus utilizing kinetic rotary energy of a spinning top for conversion to translatory motion comprising a top having a stem and a body portion, stationary guidance means having a runway for supporting the spinning top on one end of the stem in a substantially vertical orientation, the guidance means further having acceleration means including an elongated member mounted within said runway, said member being adapted for providing a contact surface for said end of the stem and for magnetically interacting therewith to impart a linear velocity to the top.
Claim 3
Dependent Claim
26 words
A dynamic toy apparatus as claimed in claim 1 wherein the acceleration means includes an accelerator track, said track being provided with an elongated ferrous member.
Claim 4
Dependent Claim
32 words
A dynamic toy apparatus as claimed in claim 2 wherein the accelerator track is provided with side barriers along the margin of said runway for confining said spinning top within the runway.
Claim 5
Dependent Claim
41 words
A dynamic toy apparatus as claimed in claim 3 wherein the runway defines a sloped surface from each of the side barriers toward a longitudinal axis of the track member for urging the spinning top into contact with the acceleration means.
Claim 6
Dependent Claim
36 words
A dynamic toy apparatus as claimed in claim 2 wherein the runway includes a plurality of apertures and the elongated member defines a rod, said rod being mounted to said runway by engagement with respective apertures.
Claim 7
Dependent Claim
50 words
A dynamic toy apparatus as claimed in claim 5 wherein a plurality of apertures are provided along the runway, said accelerator track further being flexibly deformable for registering selected apertures for engagement with said rod, said rod being fixedly held in position by the flexible action of the accelerator track.
Claim 8
Dependent Claim
38 words
A dynamic toy apparatus as claimed in claim 1 wherein the acceleration means includes an accelerator track, said track being provided with an elongated T-shaped member, said accelerator track further including a recess for accommodating said T-shaped member.
Claim 9
Dependent Claim
38 words
A dynamic toy apparatus as claimed in claim 1 wherein the acceleration means includes an accelerator track, said track including a vertically oriented planar member, said accelerator track further including a longitudinal groove for accepting said planar member.
Claim 10
Dependent Claim
45 words
A dynamic toy apparatus as claimed in claim 1 wherein said acceleration means includes an accelerator track, said track including a dual sided strip, said strip being engageable over a complementary notched rail, said rail being accommodatable within a recess formed in said accelerator track.
Claim 11
Dependent Claim
45 words
A dynamic toy apparatus as claimed in claim 1 wherein the guidance means further includes a coaster track, said coaster track having a runway defining longitudinal groove means for accommodating said end of the stem portion of the spinning top when traversing said coaster track.
Claim 12
Dependent Claim
38 words
a dynamic toy apparatus as claimed in claim 10 wherein the guidance means further includes a curved track, said curved track having a runway defining a median barrier for altering the path of travel of the spinning top.
Claim 13
Dependent Claim
39 words
A dynamic toy apparatus as claimed in claim 11 wherein the track is provided with flange means below said runway, a track connector, said flange means being adapted for slidably receiving the track connector whereby contiguous tracks are interconnected.
Claim 14
Dependent Claim
32 words
A dynamic toy apparatus as claimed in claim 12 further including pylon means for supporting the track members at selected elevations, said pylon means having coupling means for engaging said track connector.
Claim 15
Dependent Claim
31 words
A dynamic toy apparatus as claimed in claim 11 including a track connector having projecting lugs, said tracks being provided with companion recesses for receiving mating lugs to interlock contiguous tracks.
