Abstract
Abstract An elongate strip of stiff flexible sheet material having formed therein a row of openings and provided with a plurality of bounding walls upstanding from the strip and each extending about a respective opening. The strips may be frictionally connected by nesting the bounding walls of one strip in the opening of another.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
201 words
A toy construction comprising an elongate thin strip of stiff flexible sheet material of uniform thickness adapted to be readily severable into a plurality of pieces of variable lengths, said strip being provided wIth a single row of noncircular openings arranged longitudinally along said strip, said openings being in the form of thin substantially deep cup-shaped elements protruding beyond one side of said thin strip, each of said cupshaped elements having a plurality of lateral bounding walls of substantially the same thickness as said strip upstanding from said strip and inwardly extending depressions formed in the external surface of each of said bounding walls, said cup-shaped elements of a plurality of said strips being nestable in interfitting frictional and nonrotatable relationship with each other in a plurality of relative positions, said strip having a sufficient number of said openings to provide said plurality of pieces, with at least two said pieces each having two said openings therein wherein an article may be formed from a plurality of said pieces, and the buildup of strip thickness for any number of stacked strips or pieces is substantially equal to the summation of stacked strip thicknesses, whereby a compactly shaped article may be made.
Claim 2
Dependent Claim
201 words
A toy construction comprising an elongate thin strip of stiff flexible sheet material of uniform thickness adapted to be readily severable into a plurality of pieces of variable lengths, said strip being provided wIth a single row of noncircular openings arranged longitudinally along said strip, said openings being in the form of thin substantially deep cup-shaped elements protruding beyond one side of said thin strip, each of said cupshaped elements having a plurality of lateral bounding walls of substantially the same thickness as said strip upstanding from said strip and inwardly extending depressions formed in the external surface of each of said bounding walls, said cup-shaped elements of a plurality of said strips being nestable in interfitting frictional and nonrotatable relationship with each other in a plurality of relative positions, said strip having a sufficient number of said openings to provide said plurality of pieces, with at least two said pieces each having two said openings therein wherein an article may be formed from a plurality of said pieces, and the buildup of strip thickness for any number of stacked strips or pieces is substantially equal to the summation of stacked strip thicknesses, whereby a compactly shaped article may be made.
Claim 3
Dependent Claim
48 words
A toy construction according to claim 1, said openings being equally spaced apart for engagement of a selected adjacent pair of said bounding walls into a selected other adjacent pair of said bounding walls upon passage through the openings associated with said other adjacent pair of bounding walls.
Claim 4
Dependent Claim
22 words
A toy construction according to claim 2, said openings being substantially congruent to each other for conforming engagement of said bounding walls.
Claim 5
Dependent Claim
29 words
A toy construction according to claim 3, said bounding walls each being convergent in the direction away from said strip for snug frictional interfitting relation of engaging bounding walls.
Claim 6
Dependent Claim
40 words
A tory construction according to claim 4, wherein said cup-shaped elements are formed with an end wall extending across the upper end of each bounding wall, whereby each bounding wall and its associated end wall effectively close the associated opening.
Claim 7
Dependent Claim
25 words
A toy construction according to claim 4, said bounding walls each conformably bounding its associated opening, whereby engaging walls are nonrotatably engaged with each other.
Claim 8
Dependent Claim
24 words
A toy construction according to claim 6, in combination with a similar strip, said similar strip having a peripheral flange effectively rigidifying the latter.
Claim 9
Dependent Claim
25 words
A toy construction according to claim 1, wherein said inwardly extending depressions form diverging grooves terminating at outermost protruding ends of said upstanding bounding walls.
