3D pop-up card
The invention concerns a 3D pop-up card having a foldable base card which has an inner side and an outer side, the base card being foldable along a fold and being reversibly transferable from a folded, closed state to an unfolded, open state, wherein a foldable figure is fixed to the inner side of the base card and the foldable figure unfolds autonomously into a three-dimensional structure when the base card is transferred into an open state, wherein the base card is double-layered, the layer which is on the inside in the closed state having at least one slit on each of the two sides of the fold the base card and the foldable figure being connected to one another via L-shaped connecting pieces, and the first leg of an L-shaped connecting piece engaging in a slit and the second leg of an L-shaped connecting piece being attached to the foldable figure.
1. A 3D pop-up card having;
a foldable base card which has an inner side and an outer side, the base card being foldable along a fold and being reversibly transferable from a folded, closed state to an unfolded, open state;
a foldable figure fixed to said inner side of said base card and said foldable figure unfolds autonomously into a three-dimensional structure when said base card is transferred into said open state, wherein said base card has at least one slit on said inner side on either side of said fold; and
L-shaped connecting pieces that are separate and distinct from said foldable base card and said foldable figure, wherein each of said L-shaped connecting pieces has a first leg and a second leg with indentation folds between said first leg and said second leg, wherein each of said L-shaped connecting pieces can fold along any of said indentation folds, and wherein said first leg of each of said L-shaped connecting pieces engages said at least one slit and the each said second leg attaches to said foldable figure, therein connecting said foldable figure to said foldable base card.
2. The 3D pop-up card according to claim 1 , wherein at least one slit includes slits on both sides of said fold wherein said slits are offset from each other.
3. The 3D pop-up card according to claim 1 , wherein said at least one slit includes a single slit that is arranged on each side of said fold.
4. The 3D pop-up card according to claim 1 , wherein said fold is centered on said base card.
5. The 3D pop-up card according to claim 1 , wherein said inside layer and said outside layer of said base card are glued to one another.
6. The 3D pop-up card according to claim 1 , wherein said foldable figure has horizontal and vertical elements, wherein said horizontal and vertical elements are arranged perpendicular to one another in said open state.
7. The 3D pop-up card according to claim 1 , further including a light, acoustic elements and a switch for activating said light and said acoustic elements.
8. The 3D pop-up card according to claim 7 , wherein said light and said acoustic elements are arranged between said inner side and said outer said of the base card.
