Abstract: A height-adjusting collapsible mechanism for a button key includes a pair of collapsible means for supporting the button key to move up or down above a substrate. At least one collapsible means has two levers pivotally crossed to form a cross angle in between. The levers have two bottom ends pivotally engaged with the substrate and spaced from each other at an interval. One of the bottom ends is located on a stopper slidable on the substrate. Moving the stopper may change the interval and the cross angle, and may thus in turn change the free height of the button key when external forcing is absent from the button key.

Abstract: A portable keyboard comprises a flexible substrate, at least two key groups disposed on the flexible substrate, a circuit board disposed on the flexible substrate, a connector electrically connected to the circuit board and a fixative element having a first connecting portion and a second connecting portion disposed on the substrate. As the flexible substrate is properly tensed to let the first connecting portion join the second connecting portion, the overlapped key groups and the circuit board are all wrapped by the flexible substrate. The folded keyboard is pocket size and easily transported and deployed.

Abstract: A pivot shaft structure for scissor mechanisms consists of a pivot shaft and a matching receiving hole. The pivot shaft includes at least a turning contour formed by a portion of the shaft contour of a pseudo turning shaft and a constraint contour formed by removing another portion of the pseudo turning shaft. The receiving hole has an hole contour for matching the pivot shaft and includes at least a matching turning contour formed by a portion of an hole contour of a pseudo turning shaft opening and a matching constraint contour formed by filling another portion of the pseudo turning shaft opening. Through the matching between the pseudo turning shaft and the pseudo turning shaft opening, the turning contour of the pivot shaft may pivotally turn in the matching turning contour of the receiving hole, and through contact between the constraint contour of the pivot shaft and the matching constraint contour of the receiving hole to form a turning limitation for the pivot shaft in the receiving hole.
