Patent attributes
A foldable device includes a housing, a foldable display coupled to the housing, and a hinge mechanism at a bendable section of the foldable display. The hinge mechanism includes hinge track modules movably coupling adjacent pairs of hinge beams. Each hinge track module includes a track member coupled to one of the pair of hinge beams. The track member includes an arcuate slot. First and second hinge shaft members positioned at first and second sides of the track member are coupled to the other of the pair of hinge beams. The first and second hinge shaft members include a hinge shaft slidably coupled in the arcuate slot of the track member. Outer peripheral contours of the hinge shafts correspond to an inner peripheral contour of the arcuate slot to guide movement of the hinge shafts in the arcuate slot and maintain the foldable display within allowable bending limits.
