Abstract
A manipulative disk puzzle comprised of three identically shaped pieces which interfit to form a geometric solid which appears to have the form of a plurality of stacked disks. Each piece has a plurality of disk tri-sections which are integrally fastened to one another and offset from each other approximately 60 degrees. The pieces are also provided with a plurality of holes in which manipulative pegs are inserted having a depth equal to two layers. Thus, when the pegs are between two separable surfaces the interfitted pieces are locked together.
Claims34
A puzzle comprising:
- at least two separate puzzle pieces which are interfittable to form an integral piece having a predetermined configuration;
- each of said puzzle pieces including surface markings similar in appearance to the interfitting surfaces of said puzzle pieces to disguise the interrelationship of said puzzle pieces;
- and
- at least one slidable insert member which is slidably movable through apertures extending through said puzzle pieces when aligned in the predetermined configuration, said insert member being movable between a plurality of different positions relative to said puzzle pieces, said insert member having at least one position which enables said puzzle pieces to be moved apart from one another and said insert member having a plurality of positions which prevent said puzzle pieces from being moved from the predetermined configuration.
A puzzle comprising:
- at least two puzzle pieces, each of said puzzle pieces having multiple offset layers, interfittable to form an integral piece of predetermined shape, each of said puzzle pieces having a plurality of apertures formed therethrough, every aperture in each of said puzzle pieces being aligned with an aperture in at least one other of said puzzle pieces when said puzzle pieces form said predetermined shape;
- and
- a plurality of inserts for slidable movement within the apertures, each of said inserts being slidable to at least one position within aligned apertures confined in a single puzzle piece to permit disassembly of the puzzle and at least one position preventing disassembly.
A puzzle comprising:
- three substantially identical pieces which are interfittable to form a geometric solid having a predetermined configuration,
- each of said pieces having a plurality of trisected disks which are integrally fastened one beneath another, each tri-section being offset from the tri-section above approximately sixty degrees,
- each of said pieces having a plurality of apertures which are in alignment with apertures in the other pieces when they are interfitted,
- a plurality of manipulatible inserts manipulatible between apertures in the interfitted pieces which when properly positioned allow the three interfitted pieces to be separated and when not properly positioned lock the three pieces together.
The device according to claim 24 in which there are six of said inserts.
