Patent ID: 8197005

Claim:
An infant care apparatus comprising: a base; a drive mechanism coupled to the base, the drive mechanism comprising: a horizontal reciprocating assembly comprising: a first motor having a first drive shaft; a slide crank assembly comprising a gearing assembly coupled to the first drive shaft of the first motor and a crank member coupled to the gearing assembly; and a sliding stage coupled to the crank member; and a vertical reciprocating assembly disposed on the horizontal reciprocating assembly, the vertical reciprocating assembly comprising: a second motor having a second drive shaft; a worm gear assembly coupled to an output of the second drive shaft; a vertical yoke having a first end coupled to an output shaft of the worm gear assembly; and a dual scissor mechanism coupled to a second end of the vertical yoke; a controller electronically coupled to the drive mechanism; and a support device coupled to the dual scissor mechanism of the drive mechanism, the dual scissor mechanism configured to support the support device, the support device configured to be moved in both a horizontal and vertical direction relative to the base by the drive mechanism, wherein operation of the first motor causes rotation of the slide crank assembly, thereby imparting reciprocating horizontal motion to the sliding stage, operation of the second motor causes rotation of the vertical yoke, thereby imparting reciprocating vertical motion to the support device, and wherein the drive mechanism is controlled by the controller to move the support device in a plurality of motion profiles relative to the base.
