Multi-Level Crossing Maze Toy

A conventional ball carrying toy has been proposed in which an iron ball is rolled from a start portion to a goal portion of a passage formed by pins or the like on a double-construction upper plate surface, and a circular opening for causing the iron ball to be fallen on a lower plate surface to return it to the start portion and a narrow communication passage are aligned in a suitable location of said passage. A further proposal has been made in which as disclosed in Japanese Utility Model Publication No. 28637/1983, a plurality of annular squares mutually associated are incorporated into a cube, a portion of the start end to the terminal of the cube is communicated by through-holes formed in the sides of the plurality of annular squares and a Celluloid ball with a bell inserted therein is inserted from the top interiorly of the cube and removed from the lower portion.

In the conventional ball carrying toy, a ball is moved from the upper portion to the lower portion within a box incorporated in plane or in cubic, and merely passes through the determined passage, and therefore, it is possible to reduce the moving time from the start portion to the goal portion through the technical exercise but a brain judgement, a thinking power and a patience cannot be naturally learned.

The present invention relates to a multi-level crossing maze toy suitable for use with a maze game in which a ball introduced into a maze to compete for time from an entrance to an exit of the maze.

It is an object the present invention provide a means in which a complicated maze invisible from outside is formed interiorly of a combined cube or a complicated maze a part or whole of which can be seen through from the out side is formed so that one may remind of the structure of the maze and pleasantly naturally learn the brain judgement, thinking power and patience.

It is a further object of the present invention provides a means in which a complicated maze invisible from outside is formed interiorly of a combined cube or a complicated maze a part or whole of which can be seen through from the outside is formed the predetermined maze by a combined hexahedron which is combined and adhered to one another the single cubes.

It is another object of the present invention to provide a means in which a combined hexahedron is held within a frame or box and said combined hexahedron can be seen or can not be seen through from the outside is formed so that a maze is formed at each occasion a desirable structure by combining the single cubes.
