Abstract: A rocking bed includes a driving and support assembly comprising first and second drive sources each including a rotating shaft, a wheel fixedly mounted on the rotating shaft, and a first link having one end contacting the wheel, a plurality of second links each coupled to the other end of the first link, front and rear transverse beams mounted at a height above a bottom of the driving and support assembly, a plurality of braces each secured to either end of each of the transverse beams, and a plurality of third links each coupled to the second link; a bedstead comprising four legs and a plurality of fasteners each having a lower bearing for rotatably supporting the third link passing through; and a plurality of guy members each having an upper member pivotably coupled to the brace and a lower end secured to the leg.

Abstract: The present invention discloses an electric-powered mechanical single-plank bed or chair comprising a hanging frame disposed separately at four corners of a bed base, a suspending stand disposed under a single bed plank, such that a suspensor is installed between the hanging frame and the suspending stand for sustaining a heavy weight, and a plurality of motive power motors are installed in the bed base and a cam is installed at a spindle of the motive power motor and engaged at a position under the bed plank corresponding to the driving frame for limiting its position, so that when the motive power motor is turned on to drive the cam to operate, the bed plank is pushed back and forth by the cam to produce a back-and-forth or sideway sway, so as to achieve the swaying effect by a mechanical method.
