Three-Dimensional Brain Teaser

摘要

The invention pertains to toys, more specifically to mechanical three-dimensional brain teasers, which can be used for play and also as a training device for developing manual dexterity, a souvenir or an educational aid. The three-dimensional brain teaser is in the form of a body of revolution having three continuous grooves on the surface thereof, which are arranged symmetrically about the body of revolution and intersect at six points. Movable components capable of moving along one continuous groove and from one continuous groove into another are arranged in the continuous grooves. The points of intersection of the continuous grooves lie in three half planes, wherein the points of intersection of each pair of the three continuous grooves lie in the same half plane, and the sections of the continuous grooves arranged between said points of intersection contain an equal number of movable components, and the remaining two sections of each continuous groove, which are located between the points of intersection in the adjacent half planes, contain an unequal number of movable components.

主权项

1. A three-dimensional brain teaser, comprising:
a body of revolution having a surface on which three continuous grooves intersect at six points, plural movable components arranged in the continuous grooves, the movable components being configured for moving along the continuous grooves and for moving from one of the continuous grooves into another of the continuous grooves wherein points of intersection of the continuous grooves are located in three half planes of the body, and points of intersection of each pair of the three continuous grooves are located in one of the half planes and sections of the continuous grooves arranged between said points of intersection contain an equal number of movable components, while two remaining sections of each said continuous groove, which two remaining sections are located between adjacent said half planes, contain an unequal number of the movable components.
