Pop-up display and pop-up display locking mechanism therefore
Erectable displays and methods of making such erectable displays are disclosed. An example apparatus includes a display apparatus including a shroud having a first sheet and a second sheet disposed in opposition to one another, the first sheet and the second sheet being connected to one another at a first end by a first joint and at a second end by a second joint. The display apparatus includes at least one support member disposed between the first and second sheets and between the first and second joints, the support member(s) being configured to outwardly bias the first and second sheets to cause the shroud to assume a curvilinear cross-sectional shape along at least a portion of a longitudinal axis of the shroud.
1. A display apparatus, comprising:
a shroud including a first sheet and a second sheet disposed in opposition to one another, the first sheet and the second sheet being connected to one another at a first end by a first joint and at a second end by a second joint; and
a support member disposed between the first sheet and the second sheet and between the first joint and the second joint, the support member being configured to outwardly bias the first sheet and the second sheet to cause the shroud to assume a curvilinear cross-sectional shape along at least a portion of a longitudinal axis of the shroud, the support member including a line of weakness extending along the support member between the first joint to the second joint and defining a first half and a second half of the support member,
wherein the display apparatus has a first state in which the first half and the second half of the support member are folded onto one another about an axis of rotation defined by the line of weakness, and
wherein the display apparatus has a second state in which the first half and the second half of the support member are unfolded about the axis of rotation to place the first half and the second half of the support member into a substantially planar orientation, the first half and the second half of the support member being releasably locked into the substantially planar orientation by at least one of a notch of the first joint or a notch of the second joint.
2. The display apparatus of claim 1 ,
wherein the support member includes at least one of an ovoid, elliptical or oblong shape.
3. The display apparatus of claim 1 ,
wherein the first sheet and the second sheet are coupled to the support member.
4. The display apparatus of claim 3 ,
wherein the first sheet and the second sheet are coupled to the support member by adhesives.
5. The display apparatus of claim 4 ,
wherein the adhesives are applied to at least one of the first sheet, the second sheet, or one or more tabs extending from the support member.
6. The display apparatus of claim 1 ,
wherein the support member includes a first tab connecting to the first sheet by a first adhesive connection and a second tab connecting to the second sheet by a second adhesive connection.
7. The display apparatus of claim 1 ,
wherein at least one of the first joint or the second joint are formed by flaps formed at corresponding opposing lateral edges of the first sheet and the second sheet, the flaps folding inwardly to project into an interior volume of the shroud,
wherein the flaps engage correspondingly dimensioned slots in the support member, and
wherein engagement of the inwardly projecting flaps of the at least one of the first joint or the second joint with the support member stops further inward transverse travel of the first joint and the second joint relative to the longitudinal axis of the shroud.
8. The display apparatus of claim 1 ,
wherein the support member is movable between the first state in which the support member does not outwardly bias center portions of the first sheet and the second sheet from one another and the second state in which the support member outwardly biases central portions of the first sheet and the second sheet away from one another along at least a portion of the longitudinal axis of the shroud.
9. The display apparatus of claim 8 ,
wherein compressive forces applied to the center portions of the first sheet and the second sheet are directed along a minor axis of the support member to cause the support member to rotate about a major axis of the support member to transition the support member from the second state to the first state.
10. The display apparatus of claim 9 ,
wherein compressive forces applied to the center portions of the first sheet and the second sheet cause outward movement of the first joint and the second joint away from the support member and out of engagement therewith.
11. The display apparatus of claim 1 ,
wherein the first sheet and the second sheet each include one or more lines of weakness transverse to the longitudinal axis, and
wherein the shroud is foldable about the one or more lines of weakness.
12. The display apparatus of claim 1 , further including:
a plurality of support members disposed between the first sheet and the second sheet and between the first joint and the second joint along the longitudinal axis of the shroud, the plurality of support members being configured to outwardly bias at least central portions of the first sheet and the second sheet away from one another along the longitudinal axis of the shroud.
13. The display apparatus of claim 12 , wherein each of the plurality of support members have an at least substantially similar ovoid, elliptical or oblong shape.
14. A method of forming a display apparatus, comprising:
disposing a first sheet having a first lateral end and a second lateral end adjacent to a second sheet having a third lateral end and a fourth lateral end;
connecting the first lateral end of the first sheet to the third lateral end of the second sheet to form a first joint;
connecting the second lateral end of the first sheet to the fourth lateral end of the second sheet to form a second joint; and
disposing a movable support member between the first sheet and the second sheet to extend between the first joint and the second joint, the movable support member including a first half and a second half,
wherein the movable support member is movable between a first position corresponding to a display apparatus stowed state to a second position corresponding to a display apparatus erected state, the first half and the second half being releasably locked into a substantially planar orientation by at least one of a notch of the first joint or a notch of the second joint in the display apparatus erected state.
15. The method of forming the display apparatus of claim 14 , further including:
deploying the display apparatus by moving the first joint toward the second joint to move the movable support member from the first position to the second position and transition the display apparatus from the stowed state to the erected state.
16. The method of forming the display apparatus of claim 15 , further including:
stowing the display apparatus by moving the first joint away from the second joint to move the movable support member from the second position to the first position and transition the display apparatus from the erected state to the stowed state.
