Abstract
Abstract Six similar and elongated right-parallelepiped parts are pivotally connected in sequence with one connection in the sequence being a side-to-end connection and the balance of the connections being side-to-side connections. The parts so arranged that they can be cooperatively and collectively brought into a single larger right parallelepiped configuration. During the various movements, two of the parts may have to pass through positions of interference with each other. To overcome this difficulty, provision is made for one or more of the connections to be yieldably displaceable or a portion of one or more of the parts to be removed. If the solid-geometrical configuration is to constitute a puzzle, the displaceable connection is concealed; if the configuration is to be used for furniture, the displaceable connection can be omitted along with one or more of the parts. In either case, additional parts may optionally be employed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
A structure comprising a plurality of parts, and means pivotally connecting said parts in sequence such that between the majority of adjacent of the parts in said sequence only pivotal displacement is possible, said parts being so connected, dimensioned and arraNged that the same can be manipulated and brought collectively into a regular solid-geometrical configuration, said means pivotally connecting said parts so that said adjacent parts are rotatable on common axes, at least one of said parts during manipulation having a position of interference with movement of another of said parts, one of said plurality of parts including accommodation means to avoid said interference without requiring the detachment of any of said parts, said parts being, at least generally, right parallelpipeds, said parts each including four similar and connected rectangular sides and opposed square ends connected to said sides, two of said parts being the endmost parts in said sequence, some of the parts being maintained by the first said means in end-to-side relationship and some of said parts being maintained in side-to-side relationship in said sequence.
Claim 2
Dependent Claim
177 words
A structure comprising a plurality of parts, and means pivotally connecting said parts in sequence such that between the majority of adjacent of the parts in said sequence only pivotal displacement is possible, said parts being so connected, dimensioned and arraNged that the same can be manipulated and brought collectively into a regular solid-geometrical configuration, said means pivotally connecting said parts so that said adjacent parts are rotatable on common axes, at least one of said parts during manipulation having a position of interference with movement of another of said parts, one of said plurality of parts including accommodation means to avoid said interference without requiring the detachment of any of said parts, said parts being, at least generally, right parallelpipeds, said parts each including four similar and connected rectangular sides and opposed square ends connected to said sides, two of said parts being the endmost parts in said sequence, some of the parts being maintained by the first said means in end-to-side relationship and some of said parts being maintained in side-to-side relationship in said sequence.
Claim 3
Dependent Claim
24 words
A structure as claimed in claim 1 wherein said parts are at least generally similar in shape to each other and to said configuration.
Claim 4
Dependent Claim
28 words
A structure as claimed in claim 1 wherein the rectangular sides have widths equal to the widths of the square ends and lengths which are double said widths.
Claim 5
Dependent Claim
44 words
A structure as claimed in claim 1 wherein the first said means are pivots and said accommodation means is a resilient seat for at least one but less than all of said pivots enabling transverse displacement of the same relative to the axis thereof.
Claim 6
Dependent Claim
22 words
A structure as claimed in claim 1 wherein at least one of said parts includes a rounded corner constituting said accommodation means.
Claim 7
Dependent Claim
42 words
A structure as claimed in claim 1 wherein the first said means are pivots and said accommodation means includes a resilient device associated with at least one but less than a majority of the pivots and allowing axial displacement of the same.
Claim 8
Dependent Claim
16 words
A structure as claimed in claim 1 wherein there are at least six of said parts.
Claim 9
Dependent Claim
16 words
A structure as claimed in claim 1 wherein said regular solid-geometrical configuration is a right parallelpiped.
