with reference now to the drawings , and in particular to fig1 through 21 thereof , a new multi - dimensional puzzle embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described . as best illustrated in fig1 through 21 , the multi - dimensional puzzle 10 generally comprises a cylindrical base member 11 having an open top and an open bottom and a bore 12 extending therethrough . the base member 11 includes a longitudinal slot 15 extending into the bore 12 and extends from the open top to the open bottom , and further includes a first lateral slot 13 and a second lateral slot 14 spaced apart and extending into the bore 12 opposite of the longitudinal slot 15 . the lateral slots 13 , 14 of the base member 11 are spaced along the length of the base member 11 with the lateral slots 13 , 14 having ends which are enlarged . a plurality of tubular members 16 , 21 are adapted to be removably received in the bore 12 of the base member 11 . each tubular member 16 , 21 has an open top , an open bottom and a bore 17 , 22 extending therethrough . the tubular members include a first tubular member 16 having a longitudinal slot 20 extending into the bore 17 thereof and extending the length thereof , and further includes a second tubular member 21 adapted to be removably received in the bore 17 of the first tubular member 16 and having a longitudinal slot 26 extending the length thereof . each of the tubular members 16 , 21 has a pair of lateral slots 18 , 19 , 23 , 24 extending into a respective bore 17 , 22 and being spaced along a length thereof with the lateral slots 18 , 19 , 23 , 24 having ends which are enlarged . a plurality of interlocking arcuate pieces are adapted to removably fit into the base member 11 and the tubular members 16 , 21 . the arcuate pieces are essentially c - shaped and include a first arcuate member 25 having enlarged ends 27 , 28 and a longitudinal slot 26 extending from near one end to near the other end thereof , and also include a second arcuate member 29 having enlarged ends 30 , 31 and being adapted to interlockingly fit into the longitudinal slot 26 of the first arcuate member 25 , and further include a third arcuate member 32 being adapted to interlockingly fit into a lateral slot 24 of the second tubular member 21 . the first arcuate member 25 is adapted to interlockingly fit into a second lateral slot 14 of the base member 11 and is adapted to partially extend into a second lateral slot 19 of the first tubular member 16 . a plurality of planar members each of which having an enlarged longitudinal edge 34 , 47 and a pair of slots 35 , 36 , 39 , 40 spaced apart and extending in the longitudinal edge , include a first planar member 33 having a longitudinal portion removably fitted in the longitudinal slots 15 , 20 , 26 of the base member 11 and the tubular members 16 , 21 , and further include a second planar member 37 being adapted to interlockingly fit into a first lateral slot 13 of the base member 11 and into a first lateral slot 18 of the first tubular 16 member and to partially extend into the first lateral slot 23 of the second tubular member 21 . the first planar member 33 includes another longitudinal edge 34 which is enlarged and is removably disposed in the bores 12 , 17 , 22 of the base member 11 and the tubular members 16 , 21 . the second planar member 37 includes an arcuate longitudinal edge to conform to a wall of the base member 11 . an arcuate plate member 41 is laterally curved and has a pair of slots 42 , 43 spaced apart and extending in a longitudinal edge thereof and being interlockingly fitted in the bore 12 of the base member 11 . one of the slots 43 of the arcuate plate member 41 is adapted to receive an enlarged end 47 portion of the second planar member 37 , and the other of the slots 42 of the arcuate plate member 41 is adapted to receive one of the enlarged ends 28 of the first arcuate member 25 . a plurality of slot - filling pieces 44 - 46 are adapted to removably fit in the slots 35 , 39 , 40 of the planar members 33 , 37 . the slot - filling members 44 - 46 are essentially small node - like bodies shaped to interlockingly fit into respective the slots 35 , 39 , 40 of the planar members 33 , 37 . in use , the user atempts to form a solid cylindrical structure . the user starts with the cylindrical base member 11 and places the first tubular member 16 inside the bore 12 of the cylindrical base member 11 , and then places the third arcuate member 32 in the second lateral slot 24 of the second tubular member 21 and places the second tubular member 21 inside the bore 17 of the first tubular member 16 . the user then places the arcuate plate member 41 inside the bore 12 of the base member 11 , and places one of slot - filling members 46 in a second slot 35 of the first planar member 33 , and then places the first planar member 33 in the longitudinal slots 15 , 20 , 26 of the base member 11 and the tubular members 16 , 21 . the user then places the second arcuate member 29 in the longitudinal slot 27 of the first arcuate member 25 and places the first arcuate member 25 in the second lateral slots 14 , 19 of the base member 11 and the first tubular member 21 , respectively , and then places the remaining slot - filling members 44 , 45 in the slots 39 , 40 of the second planar member 37 and then places the second planar member 37 in the first lateral slots 13 , 18 , 23 of the base member 11 and the tubular members 16 , 21 and in the first slot 36 of the first planar member 33 to complete the cylindrical structure . as to a further discussion of the manner of usage and operation of the present invention , the same should be apparent from the above description . accordingly , no further discussion relating to the manner of usage and operation will be provided . with respect to the above description then , it is to be realized that the optimum dimensional relationships for the parts of the invention , to include variations in size , materials , shape , form , function and manner of operation , assembly and use , are deemed readily apparent and obvious to one skilled in the art , and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention . therefore , the foregoing is considered as illustrative only of the principles of the invention . further , since numerous modifications and changes will readily occur to those skilled in the art , it is not desired to limit the invention to the exact construction and operation shown and described , and accordingly , all suitable modifications and equivalents may be resorted to , falling within the scope of the invention .
