Abstract
A system of hinges for pop-ups. The system consists of subsystems that could function on their own if they were ideally rigid, but which are in the practical situation in sufficiently rigid. The subsystems are interconnected by extra hinged connecting parts in such a way that the total system achieves as yet sufficient rigidity, but without impairing the sought pop-up movement.
Claims3
System of hinges and panels, made of sheet material, applied in a pop-up, comprising:
- (a) opening pages
- (b) a pedestal structure comprising:
- (1) at least two subsystems of hinges and panels, connected to said opening pages
- (2) at least one additional panel
- (3) at least one additional hinge
- said additional panel interconnecting said subsystems with the aid of said additional hinge in such a way that said subsystems are not restrained in their movements by said additional panel and at the same time making said pedestal structure more rigid than said subsystems would be when operating separately, because said additional panel provides extra support to said pedestal structure
- (c) at least one additional pop-up part mounted on said pedestal structure
- said system of hinges and panels having the property that said system of hinges and panels can be folded flat upon closing the opening pages and that said system of hinges and panels can be erected upon opening the opening pages, and whereby said additional pop-up part mounted on said pedestal structure increases the capability of the pop-up for making large movements and whereby said pedestal structure is sufficiently rigid to support said additional pop-up part mounted on said pedestal structure.
