Abstract
Abstract A display card of the pull card type having a swinging operating tab for sliding an intermediate display leaf between a back leaf and the display aperture of a front display leaf to shift the intermediate display leaf and change the scene or message visible through the display aperture. The front and back leaves are joined at their sides by folds which provide an envelope for the sliding intermediate leaf and which also serve as relatively long guides for the sliding intermediate leaf; and the tab has two spaced hinge-like folds, one connecting one of the two layers of the tab to the intermediate leaf and the other fold connecting its other layer to a flexible projecting section of the back leaf. The two ends of the envelope are open and the intermediate leaf may be elongated to extend beyond the end of the envelope when the tab is in the folded position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
243 words
A display-changing multilayer display device which comprises a front leaf and a back leaf joined together along two spaced and substantially opposite junctions of substantial length to form a flat envelope having two open edges on opposite ends thereof, at least one display aperture in at least one of said front and back leaves, an intermediate leaf slidably positioned between said front and back leaves and between said junctions for sliding movement beneath and relative to said display aperture, said intermediate leaf extending out of a first edge of said open edges for hinged connection with a foldable tab, said tab being affixed to a flexible section of one of said front and back leaves at an operating fold line substantially perpendicular to the direction of said sliding movement, the pivot of said hinged connection being spaced away from said fold line and toward said first open edge when said tab is in the folded position, and said pivot being located farther than said fold line from said first open edge when said tab is in the open position, and said envelope being open at a second edge of said open edges to accommodate extension of said intermediate leaf at its free end when said tab is in the folded position, whereby said intermediate leaf is shifted by the opening of said tab to present a different display area of said intermediate leaf than the display area initially visible through said display aperture.
Claim 2
Dependent Claim
243 words
A display-changing multilayer display device which comprises a front leaf and a back leaf joined together along two spaced and substantially opposite junctions of substantial length to form a flat envelope having two open edges on opposite ends thereof, at least one display aperture in at least one of said front and back leaves, an intermediate leaf slidably positioned between said front and back leaves and between said junctions for sliding movement beneath and relative to said display aperture, said intermediate leaf extending out of a first edge of said open edges for hinged connection with a foldable tab, said tab being affixed to a flexible section of one of said front and back leaves at an operating fold line substantially perpendicular to the direction of said sliding movement, the pivot of said hinged connection being spaced away from said fold line and toward said first open edge when said tab is in the folded position, and said pivot being located farther than said fold line from said first open edge when said tab is in the open position, and said envelope being open at a second edge of said open edges to accommodate extension of said intermediate leaf at its free end when said tab is in the folded position, whereby said intermediate leaf is shifted by the opening of said tab to present a different display area of said intermediate leaf than the display area initially visible through said display aperture.
Claim 3
Dependent Claim
80 words
A display device according to claim 1 wherein said intermediate leaf is provided with an extended member which extends beyond said second edge when said tab is in the folded position to present an additional display area of said intermediate leaf when said tab is in the folded position whereby when said intermediate leaf is shifted, to present a different area of said intermediate leaf than the display area initially visible through said display aperture and on said extended member.
Claim 4
Dependent Claim
25 words
A display device according to claim 2 wherein said extended member also extends beyond said second edge when said tab is in the open position.
Claim 5
Dependent Claim
41 words
A display device according to claim 3 wherein at least one of said junctions is disposed along a straight line and serves as a guide means for rectilinear motion of an adjacent and substantially parallel straight edge of said intermediate leaf.
Claim 6
Dependent Claim
13 words
A display device according to claim 4 wherein said junctions are substantially parallel.
Claim 7
Dependent Claim
20 words
A display device according to claim 5 wherein said front, back and intermediate leaves are of a substantially rectangular shape.
Claim 8
Dependent Claim
157 words
A display device according to claim 6 which comprises a single sheet of flexible material folded along a first fold line substantially perpendicular to the direction of said rectilinear sliding motion to provide said intermediate leaf overlying said back leaf, said sheet being folded along a second fold line substantially parallel to the direction of said motion to superimpose said front leaf over said intermediate leaf and to form one of said junctions, said back leaf having a third fold line substantially perpendicular to the direction of said motion and at a substantial distance from said first open edge of said envelope to provide said operating fold line of said tab, and said intermediate leaf having a fourth fold line substantially perpendicular to the direction of said motion to form said hinged connection to said tab at a location between said third fold line and said first open edge when said tab is in the folded position.
Claim 9
Dependent Claim
29 words
A display device according to claim 7 wherein said tab comprises two layers of said flexible material joined at said first fold line and at said fourth fold line.
Claim 10
Dependent Claim
34 words
A display device according to claim 7 wherein said tab comprises two layers of said flexible material united over substantially the entire area extending from said first fold line to said fourth fold line.
Claim 11
Dependent Claim
39 words
A display device according to claim 7 wherein one of said front and back leaves is folded along a fifth fold line substantially parallel to and spaced from said second fold line to provide the second of said junctions.
Claim 12
Dependent Claim
90 words
A display device according to claim 10 wherein said single sheet is substantially L-shaped, having a generally short leg member orthogonally intersecting a generally long leg member, said front leaf being formed by folding said short leg member along said second fold line substantially coincident with the intersection of said short and long leg members, and said fifth fold line being formed on said short leg member substantially near its free end and spaced from said second fold line a distance equal to about the width of said back leaf.
Claim 13
Dependent Claim
26 words
A display device according to claim 11 wherein the width of said intermediate leaf is slightly less than the widths of said front and back leaves.
Claim 14
Dependent Claim
86 words
A display device according to claim 11 wherein said extended member of said intermediate leaf is folded over said front leaf along a sixth fold line, substantially parallel to said first fold line, to cover a portion of said front leaf near said second edge when said tab is in the folded position such that when said tab is shifted to its open position, said extended member flips over as said intermediate leaf slides within said envelope to expose the entire surface of said front leaf.
