ABSTRACT:
A convertible rocking cradle is equipped with a mounting base and a cradle body that can be locked together or unlocked so as to permit the cradle body to be reciprocally rocked in the longitudinal direction by way of a motor; or the cradle body secured to the mounting base can be pushed all around. Each corner of the mounting base is disposed a wheel or castor so that it can be movable. On each longitudinal side of the mounting base is provided with a vertical F-shaped slide track which is engaged with the rollers disposed on the corresponding side of the cradle body. A motor with a gear mounted onto the shaft thereof is secured to the underside of the cradle body. A rack longitudinally disposed at the middle of the mounting base is in mesh with the gear driven by the motor so that the cradle body can be driven therealong. A limit switch located at 1/3 position from each end of the rack is used to make the motor reversely rotated so that the cradle can be reciprocally rocked in the longitudinal direction. A latch placed at each side of the cradle body is selectively engaged with a locking retainer, permitting the mounting base and the cradle body to be selectively combined together.
