Abstract
Abstract A novelty toy device for forming a variety of geometric configurations. The device is constructed of a series of uniquely shaped members which form at least one closed loop. The members are joined together such that each member is axially rotatable with respect to adjacent members, thereby enabling the members to be twisted into a variety of shapes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
75 words
A twistable novelty device consisting of: six rigid tubular elbows each having a generally L-shaped configuration rotatably connected end to end forming a single closed loop structure, each abutting pair of elbows being mutually rotatable about the axis common to the abutting ends of said pair without axial displacement therebetween, said elbows being joined together to form a structure in which each leg of the elbows lie in one of two generally perpendicular intersecting planes.
Claim 2
Dependent Claim
75 words
A twistable novelty device consisting of: six rigid tubular elbows each having a generally L-shaped configuration rotatably connected end to end forming a single closed loop structure, each abutting pair of elbows being mutually rotatable about the axis common to the abutting ends of said pair without axial displacement therebetween, said elbows being joined together to form a structure in which each leg of the elbows lie in one of two generally perpendicular intersecting planes.
Claim 3
Dependent Claim
54 words
A twistable novelty device comprising: eight L-shaped and two T-shaped rigid tubular elbows rotatably connected end to end forming two interconnected loops, all of the ends of said elbows being interconnected, each abutting pair of elbows being mutually rotatable about the axis common to the abutting ends of said pair without axial displacement therebetween.
Claim 4
Dependent Claim
54 words
A twistable novelty device comprising: eight L-shaped and two T-shaped rigid tubular elbows rotatably connected end to end forming two interconnected loops, all of the ends of said elbows being interconnected, each abutting pair of elbows being mutually rotatable about the axis common to the abutting ends of said pair without axial displacement therebetween.
Claim 5
Dependent Claim
119 words
A twistable novelty device comprising: a plurality of rigid tubular elbow members, each having a generally L-shaped configuration rotatably connected end to end forming a single closed loop structure, each abutting pair of elbows being mutually rotatable about the axis common to the abutting ends of said pair, and wherein each elbow is internally threaded with a screw-like thread at one end and correspondingly externally threaded at the other end, the externally threaded end of each elbow being partially threadingly inserted within the internally threaded end of the abutting elbow, such that as the elbows are rotated, lateral alternatingly axially inward and outward threaded movement occurs between each adjoining pairs of elbows, without separation of the pairs of elbows.
Claim 6
Dependent Claim
119 words
A twistable novelty device comprising: a plurality of rigid tubular elbow members, each having a generally L-shaped configuration rotatably connected end to end forming a single closed loop structure, each abutting pair of elbows being mutually rotatable about the axis common to the abutting ends of said pair, and wherein each elbow is internally threaded with a screw-like thread at one end and correspondingly externally threaded at the other end, the externally threaded end of each elbow being partially threadingly inserted within the internally threaded end of the abutting elbow, such that as the elbows are rotated, lateral alternatingly axially inward and outward threaded movement occurs between each adjoining pairs of elbows, without separation of the pairs of elbows.
Claim 7
Dependent Claim
74 words
A novelty device according to claim 2, wherein, each said elbow has an outwardly extending rim member adjacent one end thereof and a ledge member adjacent the other end thereof and wherein the rim member of one elbow is rotatably disposed in the ledge member of an adjacent elbow such that each abutting pair of elbows is mutually rotatable about the axis common to the abutting ends of said pair without axial displacement therebetween.
