Patent ID: 7025351

Claim:
A manipulative puzzle which comprises a first member and a second member pivoted for rotation in relation to said first member about an axis, which comprises a set of annular elements, each element defining a bore and defining a keyway at the periphery of the bore, which comprises a semi-tubular limiter, and which displays a form in which said limiter coaxially pins said elements on an equable arbor for rotation about said axis, in which said first member and said second member are mutually engaged longitudinally of said axis, in which said limiter is engaged with said second member for simultaneous rotation therewith relative to said first member, in which said limiter is slidable in relation to said second member whereby said elements may be moved, in which certain rotations of said second member relative to said first member permit respective rotations of an exclusive lot of said elements, the make-up of which lot is variable by movements of said elements longitudinally of said axis in relation to said first and second members, whereas said limiter joins a housing delimiting a storage space at one end of said arbor, said housing including a detachable lid which closes off said storage space, and whereas depending on the deconstruction of said form by the withdrawal of said members from said bore, said limiter permits the unpinning of said elements through the application of controlled manipulative forces , thereby providing a way of detaching said lid and gaining manipulative access to the contents if any of said storage space.
