Abstract
Display device including a unitary, rigid sheet defining a left center panel, a right center panel pivotally connected to the left center panels, a left side panel pivotally connected to the left center panel and a right side panel pivotally connected to the right center panel. Vertically extending separation lines are formed on a rear planar layer without penetrating or cutting a front planar layer so that the panels are able to pivot about vertical axes. Fold lines may be formed opposite the separation lines on the front planar layer to facilitate folding the sheet whereby the fold lines define the vertical axes about which the panels pivot. Folding of the sheet provides a compact configuration which enables the display device to be easily carried.
Claims14
A display board, comprising:
- a substantially planar center panel having a front face, a rear face and a vertical fold or bend line extending between upper and lower edges of said front face that enables folding of said center panel about said fold or bend line;
- a substantially planar left side panel pivotally connected to a left edge of said center panel, said left side panel having a front face;
- a substantially planar right side panel pivotally connected to a right edge of said center panel, said right side panel having a front face;
- rotation means for enabling said left and right side panels to rotate almost 360° relative to said center panel, said rotation means being arranged such that said left side panel is inwardly foldable relative to said center panel to enable said front face of said left side panel to face said front face of a first portion of said center panel on a first side of said fold or bend line and such that said right side panel is inwardly foldable relative to said center panel to enable said front face of said right side panel to face said front face of a second portion of said center panel on a second side of said fold or bend line;
- and
- a one-piece flap integrally connected to said upper edge of said center panel about a fold or bend line and spanning across said fold or bend line of said center panel such that said flap spans across portions of said center panel on both sides of said fold or bend line of said center panel, said flap including a fold or bend line aligning with said fold or bend line of said center panel and having a front face contiguous with said front face of said center panel, said fold or bend line being arranged to pivot rearward to stabilize the display board when said left and right side panels are arranged at an acute angle relative to said center panel,
- said flap being arranged relative to said center panel to provide the display board with a stable display state in which said front face of said center panel faces a forward direction, said front faces of said left and right side panels are arranged at an acute angle to said front face of said center panel and said flap is pivoted rearward about said fold or bend line between said flap and said center panel to be at an acute angle to said rear face of said center panel.

A display board, comprising:
- a substantially planar center panel including a fold or bend line in an approximate middle region which enables said center panel to be folded, said fold or bend line extending between lower and upper edges of said center panel;
- a substantially planar left side panel pivotally connected to a left edge of said center panel and having a width about the width of said center panel such that said left side panel is foldable against said center panel;
- a substantially planar right side panel pivotally connected to a right edge of said center panel and having a width about the width of said center panel such that said right side panel is foldable against said center panel;
- and
- a one-piece flap integrally connected to said upper edge of said center panel about a fold or bend line, said flap including a flap fold or bend line aligning with said fold or bend line of said center panel and having a front face contiguous with said front face of said center panel, said flap being arranged to pivot rearward to stabilize the display board when said left and right side panels are arranged at an acute angle relative to said center panel,
- said flap having a first portion on one side of said flap fold or bend line and a second portion on the other side of said flap fold or bend line such that said flap spans across portions of said center panel on both sides of said fold or bend line of said center panel,
- said flap being arranged relative to said center panel to provide the display board with a stable display state in which said front face of said center panel faces a forward direction, said front faces of said left and right side panels are arranged at an acute angle to said front face of said center panel and said flap is pivoted rearward about said fold or bend line between said flap and said center panel to be at an acute angle to a rear face of said center panel.
