Pop-up display with translating stop member
A pop-up display apparatus includes a shroud having first and second sheets disposed in opposition to one another, the first and second sheets being connected to one another at a first side by a first joint and at a second side by a second joint. A stop member is disposed between the first and second sheets between the first and second joints and is connected to the first and second joints at a first height of the shroud. The stop member includes first and second stop elements arranged for translational movement in opposite directions relative to one another between a first and a second position. An elastic member, separate from the stop member, is connected to the first and second joints at a second height, the elastic member and being configured to bias the first joint toward the second joint. The first position of the stop member corresponds to a stowed state of the pop-up display and a substantially flat shroud profile and the second position of the stop member corresponds to a deployed state of the pop-up display and a convex shroud profile.

wherein the stop member is affixed at a first end to the first joint formed by the first flap and the second flap.
5. The pop-up display apparatus of claim 4 ,
wherein the stop member is affixed at a second end to the second joint formed by the third flap and the fourth flap.
6. The pop-up display apparatus of claim 5 ,
wherein the stop member is affixed to the first joint, at the first end, via a first tab passing through a slot formed in the first flap and the second flap.
7. The pop-up display apparatus of claim 6 ,
wherein the stop member is affixed to the second joint, at the second end, via a second tab passing through a slot formed in the third flap and the fourth flap.
8. The pop-up display apparatus of claim 7 ,
wherein the first stop element is affixed to the first joint via the first tab, and
wherein the second stop element is affixed to the second joint via the second tab.
9. The pop-up display apparatus of claim 1 ,
wherein at least a third line of weakness and a fourth line of weakness is formed between the first stop element and the second arm to permit rotation of the second arm relative to the first stop element, the third line of weakness being spaced apart from the fourth line of weakness by a second distance, the second distance being greater than the thickness of the second stop element.
10. The pop-up display apparatus of claim 9 ,
wherein at least one of the first arm and the second arm include a locking tab.
11. The pop-up display apparatus of claim 1 ,
wherein the shroud includes a plurality of segments defined by lines of weakness formed in the first sheet and the second sheet.
12. The pop-up display apparatus of claim 11 ,
wherein each of the plurality of segments includes a stop member and an elastic member, the stop member and the elastic member being separated from one another in the segment.
13. The pop-up display apparatus of claim 12 ,
wherein each of the stop members includes a first stop element and a second stop element arranged for translational movement in opposite directions relative to one another between a first position and a second position.
14. The pop-up display apparatus of claim 1 ,
wherein compressive forces applied to central portions of the first sheet and the second sheet overcome the bias of the elastic member and move the stop member from the second position corresponding to the deployed state to the first position corresponding to the stowed state.
15. A method of forming a pop-up display apparatus, comprising:
disposing an elongated first sheet having a first lateral flap and a second lateral flap adjacent to a second elongated sheet having a third lateral flap and a fourth lateral flap, each of the first elongated sheet and second elongated sheet having transverse lines of weakness spaced apart along a length thereof;
connecting the second lateral flap to the third lateral flap to form a first joint;
connecting a first end of a stop member to the first joint at a first height along the elongated first sheet, the stop member including:
a first stop element and a second stop element arranged for translational movement in opposite directions relative to one another between a first position and a second position; and
a band element within which the second stop element is to translate relative to the first stop element, the band element formed from a first arm and a second arm depending from the first stop element, wherein at least a first line of weakness and a second line of weakness is formed between the first stop element and the first arm to permit rotation of the first arm relative to the first stop element, the first line of weakness being spaced apart from a second line of weakness by a distance greater than a thickness of the second stop element;
connecting a first end of an elastic member to the first joint at a second height along the elongated first sheet, the first height being spaced apart from the second height;
folding the elongated first sheet over the second elongated sheet to place the fourth lateral flap adjacent the first lateral flap;
connecting the first lateral flap to the fourth lateral flap to form a second joint and define a shroud having an enclosed volume;
