Abstract
Abstract A portable display case formed in three sections, having hinging strips interconnecting the respective sections, the hinging strips each having a center line of perforations for facilitating bending, and also having a parallel line of perforations equally spaced on either side of the center line of perforations, the distance between the parallel lines of perforations being substantially equal to the thickness of the center section of the three sections.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
202 words
A portable multisectional display case for displaying and transporting information, said case comprising: a center section having a planar front surface and a first lateral sidewall and a second lateral sidewall; at least two adjacent sections having planar front surfaces and lateral sidewalls; a first hinge means connecting said first lateral sidewall of said center section to a lateral sidewall of one of said adjacent sections and a second hinge means connecting said second lateral sidewall of said center section to a lateral sidewall of another adjacent section; both of said hinge means being formed from a web material having a center line of weakness formed by a series of spaced-apart perforations, and having a parallel line of weakness equally spaced on either side of said center line of weakness, the distance between said parallel lines of weakness being substantially equal to the thickness of said center section lateral sidewall; said adjacent sections being foldable about said hinge means from a carrying position wherein said two adjacent sections are folded to overlie said center section, and being unfoldable about said hinge means to form a display position wherein said two adjacent sections form a display surface in combination with said center section.
