This invention has to do with knockdown and
erector toys especially adapted for convenient as
sembly of miniature structures to simulate auto
motive vehicles and certain types of buildings,
bridges, .and parts thereof although other struc
tures than those referred to may be constructed
with the invention herein disclosed. The inven
tion has as an important object the provision of
a support having spaced clamping members em
bodying arcuate track means removably and slid 10
ably kdisposed in arcuately alined slots of laterally
2
spaced wings provided with spaced slots _disposed
on an imaginary arc having a -common origin for
receiving spaced arcuate track means or flanges
of spaced segments orsupporting members for
movably guiding arcuate displacement of the nip
ple about the spaced segments. >Other objects,
advantages, and functional and structural fea
tures of the invention will appear from the fol
lowing detailed specification taken with the ac
