Abstract
Abstract A track device for a toy vehicle which comprises a spiral track member having inner and outer ends to which other track members can be joined to form a track assembly such as a continuous track and being so constructed as to be axially extensible and to be mounted on a support at its portion adjacent the inner end so that by mounting it on the support an axially spirally extended course of travel for the vehicle can be formed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
187 words
A track system for a toy vehicle, comprising a first spiral track for spirally guiding the vehicle traveling thereon, said first spiral track having inner and outer ends, said first spiral track having connecting means at its inner and outer ends for connecting other tracks thereto so that a track assembly for the vehicle can be formed by connecting such tracks together, a second spiral track for spirally guiding the vehicle traveling thereon, said second spiral track having connecting means at its inner and outer ends for connecting otHer tracks thereto so that a track assembly can be fabricated by connecting such tracks together, first support means for axially and spirally suspending said first track from one vertical level toward a lower level, second support means for axially and spirally suspending said second track from a vertical level toward a lower level, a first extender track connecting one end of said first track with one end of said second track, a second extender track extending the other end of said first track with the other end of said second track so as to form a track assembly.
Claim 2
Dependent Claim
187 words
A track system for a toy vehicle, comprising a first spiral track for spirally guiding the vehicle traveling thereon, said first spiral track having inner and outer ends, said first spiral track having connecting means at its inner and outer ends for connecting other tracks thereto so that a track assembly for the vehicle can be formed by connecting such tracks together, a second spiral track for spirally guiding the vehicle traveling thereon, said second spiral track having connecting means at its inner and outer ends for connecting otHer tracks thereto so that a track assembly can be fabricated by connecting such tracks together, first support means for axially and spirally suspending said first track from one vertical level toward a lower level, second support means for axially and spirally suspending said second track from a vertical level toward a lower level, a first extender track connecting one end of said first track with one end of said second track, a second extender track extending the other end of said first track with the other end of said second track so as to form a track assembly.
Claim 3
Dependent Claim
20 words
A track system as in claim 1 further comprising third support means for supporting the lower end of said assembly.
Claim 4
Dependent Claim
36 words
A track system as in claim 1 wherein said first support means engages said first track near one end, said first track having a plurality of loops and being continuously unsupported over a plurality of loops.
Claim 5
Dependent Claim
35 words
A system as in claim 3 wherein said second support means engages said second track near one end, said second track including a plurality of loops and being continuously unsupported over a plurality of loops.
Claim 6
Dependent Claim
35 words
A system as in claim 4, wherein said first support means engages said first track near one end, said first track having a plurality of loops and being continuously unsupported over a plurality of loops.
Claim 7
Dependent Claim
27 words
A system as in claim 1, wherein said spiral track member is formed of a plastic material having an elasticity sufficient to be axially and resiliently extensible.
Claim 8
Dependent Claim
47 words
A system as in claim 1, wherein said first track and said second track include respective inner and outer ends, and wherein said first support means supports said first track near its inner end and said second support means supports said second track near its inner end.
Claim 9
Dependent Claim
60 words
A system as in claim 7, wherein said first support means includes an upstanding support passing through the spiral of said first track and includes a support arm extending horizontally towards said first track, and wherein said second support means includes an upstanding support passing axially through said second track and includes a horizontal arm engaging in said second track.
