Abstract: A cradle comprises a support frame and a base. The support frame is intended to hold an infant and is provided at one end thereof with a retaining hook. The base is provided with a plurality of castors fastened pivotally therewith and is further provided with an actuating, box comprising an elastic cord which is provided at the top thereof with a plurality of engaging rings engageable with the retaining hook of the support frame. The actuating box is provided therein with a motor, a disk with a cam fastened therewith, and a swing arm provided with an eccentric wheel having a groove engageable with the bottom end of the elastic cord. The swing arm is further provided with a rotor engageable with the cam. The eccentric wheel is actuated by the cam which is in turn actuated by the motor. The elastic cord is pulled downwards by the eccentric wheel in motion so as to cause the cradle to swing downwards.

Abstract: A lifting gate controlling device for controlling the front lifting gate of a baby's crib, comprising one pair of upper mounting bars respectively secured to the front two opposite corner posts of a baby's crib at an upper level, one pair of lower mounting bars respectively secured to said two opposite corner posts at a lower level, one pair of upper sliding blocks respectively movably mounted on said upper mounting bars to hold a transverse top rail of said lifting gate, and one pair of lower sliding blocks respectively movably mounted on said lower mounting bars to hold a transverse bottom rail of said lifting gate, wherein said upper mounting bars each has a V-shaped track incorporated in a P-shaped sliding track on a front face thereof for sliding either one of said upper sliding blocks by a sliding rod; said lower mounting bars each has a stop bolt at an upper end thereof to confine the upward movement of said lower sliding blocks.

Abstract: A lifting gate controlling device for controlling the front lifting gate of a baby's crib, including a mounting bar fastened in either front corner post of a baby's crib, a slide movably mounted on the mounting bar, a lock bolt fastened in the slide and controlled by a compression spring, a movable socket and a retaining block to releasably engage into a slot on the mounting bar, so that when the top rail of the front lifting gate is moved upwardly, this causes the lock bolt to disengage from the slot on the mounting bar, thus permitting the front lifting gate to be moved from an upper limit position to a lower limit position. A slopping track is made on the mounting bar to guide the lock bolt into the slot, when the front lifting gate is moved upwards from its lower limit position, so that the front lifting gate can be locked in its upper limit position.
