Abstract

A foldable keyboard includes first, second, third and fourth segments, each movably supporting operation keys thereon. The first and fourth segments have an inner edge forming a channel defined by two opposite side walls, each defining a slot terminating at a rounded end. A connecting tab has a first end forming pivot pins movably received in the slots for retrievably receiving the connecting tab in the channel and allowing the connecting tab to rotate with respect to the first or fourth segment about the pivot pins at the rounded end. The connecting tab has a second end pivotally attached to a distal edge of the second or third segment for rotation with respect thereto. The second and third segments have a proximal end forming a channel defined by two opposite side walls each forming a slot terminating at a rounded end. A central tab has ends retrievably received in the channels of the second and third segments. Pivot pins extending from the central tab are received in the slots of the channels to allow the central tab to rotate with respect to the second and third segments.
