Claims
- 1. A double sided puzzle comprising:
- a sheet having a first side and an opposite second side formed of puzzle pieces each having a substantially triangular shape, with said puzzle pieces including at least one group wherein said puzzle pieces are congruent, and with each of said puzzle pieces including cooperating means providing for the mutual interlocking of said puzzle pieces to form said sheet, and;
- each of said puzzle pieces having a first side and an opposite second side, with said first side and said second side of each of said puzzle pieces each having markings thereon which form at least one first pattern and at least one second pattern respectively upon said first side and said second side of said sheet when said puzzle pieces are respectively assembled to form a state of said sheet wherein said at least one first pattern and said at least one second pattern are completed, whereby;
- each said first side of said puzzle pieces is oriented to face upwards and said puzzle pieces are interlockingly and properly assembled to form at least one said state of said sheet with at least one said pattern being completed thereby.
- 2. The double sided puzzle of claim 1 including:
- means providing for the mutual formation of said first state and said second state when said puzzle pieces are assembled to form said sheet, whereby;
- said first pattern and said second pattern of said double sided puzzle are simultaneously completed.
- 3. The double sided puzzle of claim 1 including:
- means precluding the mutual formation of said first state and said second state when said puzzle pieces are assembled to form said sheet, whereby;
- the formation of said second state requires the disassembly of said puzzle pieces from an assembled first state, and the reassembly of said puzzle pieces in a different arrangement from that of said first state.
- 4. The double sided puzzle of claim 1 wherein:
- said first side of said sheet includes plural patterns thereon, whereby;
- each of said plural patterns is completed by assembling said puzzle pieces respectively corresponding to each of said plural patterns to form a plurality of completed modules, and said modules are assembled to complete said sheet.
- 5. The double sided puzzle of claim 4 wherein:
- at least one of said puzzle pieces of each of said plural patterns is substantially square and respectively disposed substantially in the center of said each of said plural patterns when said double sided puzzle is completed.
- 6. The double sided puzzle of claim 1 wherein:
- said second side of said sheet includes plural patterns thereon, whereby;
- each of said plural patterns is completed by assembling said puzzle pieces respectively corresponding to each of said plural patterns to form a plurality of completed modules, and said modules are assembled to complete said sheet.
- 7. The double sided puzzle of claim 6 wherein:
- at least one of said puzzle pieces of each of said plural patterns is substantially square and respectively disposed substantially in the center of said each of said plural patterns when said double sided puzzle is completed.
- 8. The double sided puzzle of claim 1 wherein:
- each of said puzzle pieces is substantially in the form of an isosceles right triangle, and said sheet is substantially square.
- 9. The double sided puzzle of claim 8 wherein:
- at least one of said puzzle pieces is substantially square and disposed substantially in the center of said sheet when said double sided puzzle is completed.
- 10. The double sided puzzle of claim 1 wherein:
- each of said puzzle pieces is substantially in the form of an equilateral triangle, and said puzzle pieces are assembled to form said sheet comprising at least one hexagonally shaped module.
- 11. The double sided puzzle of claim 10 wherein:
- said sheet includes a plurality of said hexagonally shaped modules when said sheet is assembled from said puzzle pieces.
- 12. The double sided puzzle of claim 1 wherein:
- said puzzle pieces are all mutually congruent.
- 13. The double sided puzzle of claim 12 wherein:
- each of said puzzle pieces is of an equilateral triangular configuration.
- 14. The double sided puzzle of claim 12 wherein:
- each of said puzzle pieces is of an isosceles right triangular configuration.
- 15. The double sided puzzle of claim 1 wherein:
- said puzzle pieces comprise a first group and a second group, with said puzzle pieces of said first group being mutually congruent and said puzzle pieces of said second group being mutually congruent.
- 16. The double sided puzzle of claim 15 wherein:
- said puzzle pieces of said first group each include a plurality of extensions and said puzzle pieces of said second group each include a plurality of receptacles, with said extensions of said puzzle pieces of said first group interlockingly engaging with said receptacles of said puzzle pieces of said second group.
- 17. The double sided puzzle of claim 1 wherein:
- said cooperating means providing for the mutual interlocking of said puzzle pieces to form said sheet comprises at least one extension extending from each of said puzzle pieces and at least one cooperating receptacle formed in each of said puzzle pieces, whereby;
- said at least one extension of each of said puzzle pieces is interlockingly engageable with said at least one cooperating receptacle of each other of said puzzle pieces.
- 18. The double sided puzzle of claim 17 wherein:
- each of said puzzle pieces includes plural extensions extending therefrom and plural receptacles formed therein.
- 19. The double sided puzzle of claim 17 wherein:
- each of said extensions comprises a substantially semicircular shape, and each of said receptacles comprises a shape congruent to said substantially semicircular extensions.
- 20. The double sided puzzle of claim 17 wherein:
- each of said extensions comprises a substantially trapezoidal shape having a first base side and an opposite second side with said second side being wider than said base side, and each of said receptacles comprises a substantially trapezoidal shape congruent to said substantially trapezoidal extensions.
