Abstract
A puzzle includes pieces of different and random shapes and/or sizes, which can occupy only one position in the puzzle and which can be assembled by magnetic forces as well as by co-operating positioning projections and hollows, on the surface of the pieces. Each of the projections and recesses has a unique shape and/or size, so that the invention is particularly suitable for educational and cultural applications, more particularly for use by people with impaired vision.
Claims14
A three-dimensional puzzle, which upon completion includes plural fragment sites that each has a unique combination of size and shape, the puzzle comprising:
- plural fragments which each have a unique combination of shape and size so that each of said fragments is arranged and adapted to occupy only a single one of the fragment sites within the completed puzzle, each of said fragments being closely paired with adjacent ones of said fragments along mutually adjacent surfaces in the completed puzzle;
- at least two of said fragments each comprising at least one magnetic element oriented so that said at least two fragments are attracted to each other when positioned in their respective fragment sites within the puzzle;
- at least one surface of each of said fragments comprising at least one of a positioning protrusion and a positioning hollow, wherein a mutually adjacent surface of an adjacent one of said fragments comprises a complementary one of said positioning hollow or protrusion, each said surface having a unique arrangement of said positioning protrusion or hollow,
- wherein said fragments are adapted to be suitably positioned within the puzzle using corresponding ones of said positioning protrusion and hollow and using said magnetic elements.
A three-dimensional puzzle, which upon completion includes plural fragment sites that each has a unique combination of size and shape, the puzzle comprising:
- plural primary and plural secondary fragments which each have a unique combination of shape and size so that each of said fragments is arranged and adapted to occupy only a single one of the fragment sites within the completed puzzle, each of said fragments being closely paired with adjacent ones of said fragments along mutually adjacent surfaces in the completed puzzle;
- at least two of said fragments each comprising at least one magnetic element oriented so that said at least two fragments are attracted to each other when positioned in their respective fragment sites within the puzzle;
- and
- at least one surface of each of said fragments comprising at least one of a positioning protrusion and a positioning hollow, wherein a mutually adjacent surface of an adjacent one of said fragments comprises a complementary one of said positioning hollow or protrusion, each said surface having a unique arrangement of said positioning protrusion or hollow,
- wherein said primary and secondary fragments are arranged and constructed to form a first three-dimensional object when assembly of said primary and secondary fragments is completed, and
- wherein said secondary fragments are arranged and constructed to form a second three-dimensional object when assembly of said secondary fragments is completed.
