#CMT# #/CMT# The combinatorial geometric toy (1) comprises a support main portion, and several rotary elements (4) mounted on the outer surface in perpendicular to the axis (a) and set supported rotatably. A curb (5) is arranged in displaceable manner in the guide surface of rotary element, between the two rotary elements. The support main portion is formed as a spherical shell, whose surface is formed with a recess for entry of rotary element arranged on the pivot which is arranged with an undercut in the recess. #CMT#USE : #/CMT# Combinatorial geometric toy. #CMT#ADVANTAGE : #/CMT# Low-cost production of the toy and simplified assembly of the components of the toy is enabled, due to the cup-shaped configuration of the support main portion. Fast production of the toy is enabled. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the combinatorial geometric toy. 1 : Combinatorial geometric toy 4 : Rotary element 5 : Curb 12 : End piece a : Axis. |
