Abstract
Abstract A helical track accessory for a toy vehicle and track layout system including three easily assembled and disassembled track sections having integral tabs which are attaChed to alignment and support poles. The poles have spaced pairs of annular flanges for receiving the tabs. A deflector arm positioned at the upper end portion of the helical track provides a bearing force upon moving toy vehicles to insure the vehicle is retained on the helical track. The track and poles are simply constructed and of synthetic resin so as to be inexpensively manufactured.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A track system for toy vehicles comprising: at least one helically curved track section having a vehicle running surface and at least one guide flange projecting generally upwardly from substantially one edge of said running surface for guiding a vehicle along said running surface; flange means connected to an outer peripheral portion of said track section for attaching said track section to a support and alignment means; and means connected to said flange means for supporting and aligning said track section, said means comprises an elongated pole having spaced pairs of flanges adapted to engage said flange means connected to said track section.
Claim 2
Dependent Claim
103 words
A track system for toy vehicles comprising: at least one helically curved track section having a vehicle running surface and at least one guide flange projecting generally upwardly from substantially one edge of said running surface for guiding a vehicle along said running surface; flange means connected to an outer peripheral portion of said track section for attaching said track section to a support and alignment means; and means connected to said flange means for supporting and aligning said track section, said means comprises an elongated pole having spaced pairs of flanges adapted to engage said flange means connected to said track section.
Claim 3
Dependent Claim
61 words
A track system as claimed in claim 1, wherein: said spaced pairs of flanges are integral with said elongated pole; and said flange means comprises a tab integral with the guide flange, said tab extending generally perpendicular from said guide flange and having an opening for receiving said pole so that said tab is disposed between a pair of said flanges.
Claim 4
Dependent Claim
41 words
A track system as claimed in claim 2, including a deflector arm connected to said pole and disposed across an upper end portion of said track section spaced from said running surface for biasing a moving vehicle toward said running surface.
Claim 5
Dependent Claim
30 words
A track system as claimed in claim 1, including a deflector arm connected to and disposed across an upper end portion of said track section spaced from said running surface.
Claim 6
Dependent Claim
124 words
A track system for toy vehicles comprising: a plurality of helically curved track sections, each track section having a vehicle running surface and two oppositely disposed inner and outer guide flanges projecting from said running surface for guiding a vehicle along said running surface; means for connecting said track sections one to another to form an extended helically curved track; means connected to an outer peripheral portion of said track sections for attaching said track sections to a support and alignment means; and means connected to said attaching means for supporting and aligning said track sections, said means comprises a plurality of elongated poles, each of said poles including spaced flanges for cooperating with said attaching means to support and align said track sections.
Claim 7
Dependent Claim
124 words
A track system for toy vehicles comprising: a plurality of helically curved track sections, each track section having a vehicle running surface and two oppositely disposed inner and outer guide flanges projecting from said running surface for guiding a vehicle along said running surface; means for connecting said track sections one to another to form an extended helically curved track; means connected to an outer peripheral portion of said track sections for attaching said track sections to a support and alignment means; and means connected to said attaching means for supporting and aligning said track sections, said means comprises a plurality of elongated poles, each of said poles including spaced flanges for cooperating with said attaching means to support and align said track sections.
Claim 8
Dependent Claim
60 words
A track system as claimed in claim 5, wherein: said attaching means comprises a plurality of tabs integral with the outer guide flange, said tabs extending generally perpendicular from said outer guide flange and each having a recess; and said poles being received within the recesses of said tabs and saiD tabs being received between pairs of said pole flanges.
Claim 9
Dependent Claim
29 words
A track system as claimed in claim 5, including a deflector arm connected to a pole and spaced from said running surface for biasing vehicles toward said running surface.
