Abstract

A magnetic toy or puzzle comprising a plurality of essentially two-dimensional pieces that may be assembled to form a hollow three-dimensional object. Each piece has at least three edges, and a magnet is mounted along each edge of each piece to allow the edges of the pieces to be joined together. The magnets are preferably keyed to allow: (a) only certain edges to attach to each other; or (b) the edges of the pieces to fit together in only one orientation. The magnets allow the edges to be joined in certain configurations to obtain the three-dimensional object. A holder for the puzzle pieces is provided that adds additional puzzle possibilities.

Claims

1. A combination of:

a. a plurality of pieces, each piece having at least three edges, where attachment means are so formed on the edges that the pieces may be joined together to construct a completed form; and

b. a holder having first and second plates held in a spaced apart relation by a plurality of support members, where the plates and support members are arranged such that the pieces can be stored individually in the holder in a stacked configuration and can be stored in the holder joined together as the completed form with the support members extending through the completed form.

2. A combination as recited in claim 1, in which the attachment means comprises magnetic means for joining edges together with magnetic force.

3. A combination as recited in claim 2, in which poles of the magnetic means are so oriented that the edges may be magnetically joined together only in certain configurations.

4. A combination as recited in claim 2, in which the pieces have two sides, and means are formed on at least one of these sides for indicating an orientation of poles of the magnetic means.

5. A combination as recited in claim 2, in which the pieces comprise first and second portions that may be locked together in a manner that allows an end user to mount the magnetic means along the edges of the pieces in various orientations.

6. A combination as recited in claim 1, in which the sides of said pieces are of equal length and the attachment means allow the edges of the pieces to be joined together to form a three-dimensional geometric object.

7. A combination as recited in claim 1, in which the attachment means are keyed to allow any given edge to be joined to only certain of the other edges.

8. A combination as recited in claim 1, in which the holder further comprises a middle plate mounted on at least one support member between the first and second plates.

9. A combination as recited in claim 1, in which the holder comprises first, second, third, and fourth support members so arranged along front, back, left, and right edges of the first and second plates that the holder is symmetrical about a vertical axis extending through its center.

10. A method of assembling a three-dimensional puzzle, comprising the steps of:

a. providing a plurality of pieces, each piece having at least three edges;

b. forming attachment means on the edges such that the pieces may be joined together to construct a completed form; and

c. providing a holder having first and second plates held in a spaced apart relation by a plurality of support members;

d. stacking the pieces in the holder in a stacked configuration;

e. removing the pieces from the holder;

f. assembling the pieces into the completed form separate from the holder;

g. assembling the pieces into the completed form such that the support members extend between at least two of the pieces; and

h. restacking the pieces in the holder in the stacked configuration.
