Abstract
A pop-up device for a card, book, novelty, or the like has a sandwich-like structure including a base or back (300), a front or cover (200), and a tongue (130) disposed between. All three sections may be of equal length. The three sections are folded onto one another and glued to make the sandwich. The tongue has a protruding tab end (135) for a user to pull; the end distal the tab end is fastened to a portion of the cover. A pull-slot (325) cut out between the cover and back guides the tongue for pulling to eliminate shims. The cover is slit by two parallel cuts (210) and three crosswise creases. The cuts are parallel to the tongue. The creased portion of the cover pops up when the tongue is pulled by a user. The fold lines are perpendicular to the direction of the tongue movement.
Claims19
A device for pop-up display use by a user, comprising:
- a sheet of folded material including
- a slider first section having a first section length,
- a cover second section having a second section length and a second section width, and
- a base third section having a third section length and a third section width;
- a first fold line over which, in a first sense of rotation, the first section is folded onto the second section;
- a second fold line over which, in a second sense of rotation, the third section is folded onto the second section;
- the first section including an elongate tongue having a tongue width less than the second section width and including a tab end distal the first fold line for grasping by the user;
- a pull-slot, having a pull-slot width equal to or greater than the tongue width and less than the second section width, the tongue being disposed therethrough;
- a plurality of parallel cuts extending perpendicularly to the first fold line at least part-way through the second section, outermost ones of the cuts being separated by a cut width less than the second section width;
- at least one crease in the second section, the crease extending transversely between adjacent ones of the cuts;
- and
- means for fastening the third section to the second section proximal respective edges of the third section and the second section;
- whereby when the tab end is pulled from the pull-slot by the user pop-up portions of the second section containing the crease pop up.
A blank for a pop-up, the blank having a body length and a body width and comprising:
- a slider first section having a first section length;
- a cover second section having a second section length and a second section width equal to the body width;
- a base third section having a third section length and a third section width;
- a first fold line disposed between the first section and the second section and extending generally transversely to the body length;
- a second fold line disposed between the second section and the first section;
- the first section including an elongate tongue having a tongue width less than the second section width, the tongue including a tab end distal the first fold line for grasping by a user;
- a pull-slot, having a pull-slot width equal to or greater than the tongue width, for accepting the tongue therethrough, and less than the second section width, the pull-slot disposed along the second fold line such that the pull-slot is surrounded by continuous material of the blank;
- a plurality of parallel cuts extending perpendicularly away from the first fold line and continuing at least part-way through the second section, outermost ones of the cuts being separated by a cut width less than the second section width;
- at least one crease in the second section, the crease extending transversely between adjacent ones of the cuts;
- and
- means for fastening the third section to the second section proximal respective edges of the third section and the second section;
- whereby
- the first section may be folded over onto the second section about the first fold line in a first sense of rotation and the tongue be extended through the pull-slot,
- the third section may be folded over onto the second section about the third fold line in a second sense of rotation, the second sense of rotation being opposite to the first sense of rotation,
- adjacent outer edge portions of the third section and the second section may be fastened together, and
- when the tongue is pulled from the pull-slot the second fold line may move toward the first fold line and pop-up portions of the second section may pop up about the crease.
