Abstract:
A rolling display mechanism, including a frame supporting a display screen having a retractable portion, a first rack along the upper edge of the frame and mechanically connected to the retractable portion, a second rack along the lower edge of the frame and mechanically connected to the retractable portion, at least one torsion spring extending between the upper and lower edge of the frame, where each torsion spring of the at least one torsion spring is a helical torsion spring, a first pinion mechanically connected to the at least one torsion spring and configured to drive the first rack linearly, and a second pinion mechanically connected to the at least one torsion spring and configured to drive the second rack linearly, where rotation of the first and second pinions is transferred to in-plane movement of the retractable portion.
