Self-erectable display and automatic locking mechanism for a self-erectable display
View Patent ↗A display apparatus includes a shroud having first and second sheet portions disposed in opposition to one another, the first and second sheet portions being connected to one another at a first side by a first joint and at a second side by a second joint. A support member is disposed between the first and second sheet portions and between the first and second joints, the support member being affixed to the first and second sheet portions and movably disposed relative to the first and second joints, the support member being positionable between a closed position and an open position, the open position outwardly biasing the support member against the first and second sheet portions to cause the shroud to assume a curvilinear cross-sectional shape along a length of the shroud. Notches are formed in the first and second joints at a first position along the length of the shroud. One or more elastic members couple the support member the first and/or second joints and bias the support member into the open position and toward engagement with the notches.
1. A collapsible display, comprising:
a shroud, including a first panel and a second panel joined together along a first joint on a first side and a second joint on a second side;
a support member disposed between the first panel and the second panel, the support member movable between a first position in which a first feature of the support member is disengaged from a first feature of the first joint and a second position in which the first feature of the support member engages the first feature of the first joint, the support member coupled to the first panel and the second panel in both the first position and the second position; and
an elastic member coupling the support member to the first joint or the second joint, the elastic member biasing the support member into the second position.
2. The collapsible display of claim 1 , wherein the first feature of the first joint includes a protrusion.
3. The collapsible display of claim 1 , wherein the first feature of the first joint includes a surface extension.
4. The collapsible display of claim 1 , wherein the first feature of the support member includes a cutout received by the first joint.
5. The collapsible display of claim 4 , wherein the cutout is centrally disposed on the support member.
6. The collapsible display of claim 4 , wherein the cutout has a depth smaller than a width of the first joint.
7. The collapsible display of claim 1 , wherein the first joint includes a transitional portion adjacent the first feature of the first joint.
8. The collapsible display of claim 7 , wherein the transitional portion includes a recess forming an angled surface on the first joint.
9. The collapsible display of claim 1 , wherein the first joint includes means for securing an end of the elastic member.
10. The collapsible display of claim 9 , wherein the means for securing includes a slot disposed on the first joint.
11. The collapsible display of claim 1 , wherein the support member includes means for securing an end of the elastic member.
12. The collapsible display of claim 11 , wherein the means for securing is disposed on a line of weakness of the support member.
13. The collapsible display of claim 1 , wherein the support member is coupled to the first panel or the second panel at a first location and a second location, the first location and the second location spaced apart from the first joint and the second joint.
14. A method of forming a display apparatus, comprising:
joining a first panel and a second panel together to form a first joint on a first side and a second joint on a second side to form a shroud;
disposing a support member between the first panel and the second panel;
coupling a first side of the support member to the first panel;
coupling a second side of the support member to the second panel; and coupling an elastic member between the support member and at least one of the first joint and the second joint, the elastic member biasing the support member from a first position in which a first feature of the support member is disengaged from a first feature of the first joint toward a second position in which the first feature of the support member engages the first feature of the first joint, the support member coupled to the first panel and the second panel in both the first position and the second position.
15. The method of claim 14 , wherein the first side or the second side of the support member is to be spaced from the first feature of the first joint along an axis of the shroud.
16. The method of claim 14 , further including rotating the support member about a hinge to adjust the shroud between a collapsed position and an expanded position.
17. The method of claim 16 , wherein the support member is at least partially collapsed, via the hinge, when the shroud is in the expanded position.
18. The method of claim 14 , wherein the first feature of the support member passes through a transitional portion of the first joint when moving between the first position and the second position.
19. The method of claim 18 , wherein the transitional portion includes a recess disposed on the first joint to receive at least a portion of the support member.
20. A collapsible display, comprising:
a shroud, including a first panel and a second panel joined along a first joint on a first side and a second joint on a second side;
means for supporting disposed between the first panel and the second panel, the means for supporting movable between a first position in which a first feature of the means for supporting is disengaged from a first feature of the first joint and a second position in which the first feature of the means for supporting engages the first feature of the first joint, the means for supporting coupled to the first panel and the second panel in both the first position and the second position; and
means for coupling the means for supporting to the first joint or the second joint, the means for coupling biasing the means for supporting into the second position.
