Hinge mechanism having plate stops for a flexible display device
A foldable touch screen display device with a flexible display including segments that can be folded from a compact state to an expanded state, and including a hinge mechanism having plate stops is described. The form factor of the compact state is comparable to a handheld phone. The form factor of the expanded state is comparable to a larger phone or tablet computer. Both states may include an integrated speaker and microphone. The hinge mechanism's plate stops provide a support structure below and in between the device's flexible display segments, preventing folding beyond a flat open state to an obtuse angle. The device can include sensors to indicate the state of configuration and mechanisms for alignment, locking, and further structural support. A module attached to at least one segment of the flexible display or rigid display may contain all processing and memory, and a communications system usable in any state.
1. An apparatus comprising:
(a) a flexible touch-sensitive display comprising a first flexible touch-sensitive display portion and a second flexible touch-sensitive display portion; wherein:

(3) the flexible touch-sensitive display further comprises having a fully folded state;
(4) the flexible touch-sensitive display further comprises having a partially expanded state; and
(5) the flexible touch-sensitive display further comprises having a fully expanded state;
(b) a hinge sleeve structure connecting a first structural support and a second structural support together having at least one plate extending from the hinge sleeve structure; and
(c) a first plate integrated with the first structural support, and a second plate integrated with the second structural support, wherein the first plate or the second plate are stopped from moving when rotated against the at least one plate extending from the hinge sleeve structure; wherein
(d) the first structural support and the second structural support make up a triangulated shape in section when the apparatus is in a fully expanded state, whereby a distal end of the first structural support away from the hinge sleeve structure is at its thinnest point such that its shape tapers contiguously on at least one face of the apparatus to a thickest point at a distal end of the second structural support away from the hinge sleeve structure; and
(e) the first structural support and the second structural support make up a shape in section with a rectangular boarder when the device is in a fully folded state.
2. The apparatus of claim 1 wherein:
the at least one plate extending from the hinge sleeve structure is positioned parallel to the long top and the long bottom of the hinge sleeve structure.
3. The apparatus of claim 1 wherein:
the at least one plate extending from the hinge sleeve structure is positioned perpendicular to the long top and the long bottom of the of hinge sleeve structure.
4. The apparatus of claim 1 wherein:
the first plate is stopped by the at least one plate extending from the hinge sleeve structure when the first structural support is rotated to a folded position with respect to the second structural support.
5. The apparatus of claim 1 wherein:
the second plate is stopped by the at least one plate extending from the hinge sleeve structure when the second structural support is rotated to a folded position with respect to the first structural support.
6. The apparatus of claim 1 wherein:
the first plate is stopped by the at least one plate extending from the hinge sleeve structure when the first structural support is rotated to an unfolded position with respect to the second structural support.
7. The apparatus of claim 1 wherein:
the second plate is stopped by the at least one plate extending from the hinge sleeve structure when the second structural support is rotated to an unfolded position with respect to the first structural support.
