Abstract
Abstract A display device consisting of an elongated structure having apertures for the reception and retention of support hooks is manufactured as a molded one-piece element having two complementary sections which can be locked together. The design is such that the two portions are joined along one edge of each in a living hinge. The elongated structure can be stacked to increase the display area.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
A molded hollow, elongated unitary display structure of flexible synthetic plastic, comprising two complementary elements each having wall means, each of said wall means having a first and a second edge, apertures by which parts to be displayed may be supported, living hinge means by which said first edges are joined, locking means proximate said second edges for interengaging said second edges, integral, complementary top-wall members and integral, complementary bottom wall members within said complementary elements, said complementary members having locking means and serving to reinforce said elements and to prevent relative motion transverse to said structure and parallel to the axis of said structure, said apertures having axes parallel to each other.
Claim 2
Dependent Claim
113 words
A molded hollow, elongated unitary display structure of flexible synthetic plastic, comprising two complementary elements each having wall means, each of said wall means having a first and a second edge, apertures by which parts to be displayed may be supported, living hinge means by which said first edges are joined, locking means proximate said second edges for interengaging said second edges, integral, complementary top-wall members and integral, complementary bottom wall members within said complementary elements, said complementary members having locking means and serving to reinforce said elements and to prevent relative motion transverse to said structure and parallel to the axis of said structure, said apertures having axes parallel to each other.
Claim 3
Dependent Claim
39 words
A structure as defined in claim 1, wherein each of said elements has at least one integral rib at corresponding positions intermediate said top and bottom wall members, said ribs having locking means and serving to reinforce said structure.
Claim 4
Dependent Claim
71 words
A structure as defined in claim 1, wherein said structure is cylindrical and has a first cylinder projecting axially beyond said top wall and a second cylinder projecting axially beyond said bottom wall, the diameters of said first and second cylinders being such that one cylinder would fit with friction within the other cylinder could they be joined, thereby making said structure nestable in an axial direction with other similar structures.
Claim 5
Dependent Claim
25 words
A structure as defined in claim 3, wherein said structure is cylindrical and is provided with means to prevent relative rotation between adjacent, nested structures.
