Abstract: An electromagnetic cradle includes a support frame, a swinging table, multiple abutting members, a magnetic box, and an electromagnetic device. The support frame includes two support rods each provided with multiple rollers. The abutting members are secured to the bottom of the swinging table and rest on the rollers respectively. The magnetic box is secured to the bottom of the table board. The electromagnetic device is secured to the support frame. The electromagnetic device is located under and corresponds to the magnetic box. The electromagnetic device produces a magnetic force to attract or repel the magnetic box that is mounted on the swinging table, so as to pull or push the swinging table, such that the swinging table horizontally swings successively and reciprocatingly.

Abstract: A rotation joint structure includes a fixed joint, a movable joint, a first limit member, and a second limit member. The fixed base has a locking groove. The movable joint is pivotally connected with the fixed joint. The movable joint has a first slideway and a second slideway connected to each other. The first limit member is movably mounted in the first slideway. The second limit member is movably mounted in the second slideway. When the second limit member is locked in the locking groove, and the first limit member stops the second limit member, the movable joint is locked and cannot be rotated. Thus, the movable joint is disposed at a two-stage locking state.

The receiving recess has an inside provided with a plurality of projections and a plurality of locking grooves arranged between the projections. The movable member is connected with at least one fitting portion which has a substantially arcuate cross-section. The at least one fitting portion is fitted into the receiving recess and has an outside provided with at least one locking block locked in the locking grooves.

Abstract: A cradle includes a base unit, a swinging unit mounted on the base unit, a table board mounted on the swinging unit, and an electromagnetic unit mounted between the base unit and the table board. The electromagnetic unit includes a housing secured on the base unit, an electromagnetic device mounted in the housing, a box mounted on the table board and corresponding to the electromagnetic device, and two magnet sets mounted in the box. Thus, the electromagnetic device is started and produces a magnetism to repel or attract the two magnet sets which drive the table board to swing reciprocally.

Abstract: A remote surveillance composite machine includes a primary device and a secondary device wirelessly connected with and driven by the primary device. The secondary device includes a housing provided with a recess, a pivot member and a locking member. The secondary device is used individually or connected with a hanging arm which is mounted on a baby playpen. The hanging arm has a distal end provided with a pivot hole and a locking hole. The recess is mounted on the distal end of the hanging arm. The pivot member is connected with the pivot hole. The locking member is locked in the locking hole. Thus, the secondary device is mounted on the distal end of the hanging arm and is located above the playpen to face the baby.

Abstract: A foldable stroller includes a main frame, a support unit, two fixed side units, two movable side units, and a guardrail. The main frame includes two joints, two upper connectors, a handlebar, two lower connectors, a lower bar and two front wheels. Each of the two fixed side units includes a leg, a first locking member, a first spring, a fixed block, a release member, a ramp, a pull handle, a second spring, a wheel support and a rear wheel. Each of the two movable side units includes a movable block, a press knob, an extension, a second locking member, a third spring and two braces. Thus, the first locking member and the second locking member construct a two-stage locking mechanism, to lock the stroller steadily, thereby preventing the stroller from being folded accidentally.

Abstract: An electromagnetic cradle includes a track assembly, a sliding assembly, a rocking bed and a bottom frame. The track assembly includes two tracks, and an electromagnetic device mounted on one of the tracks. Each of the tracks has a first slideway and a second slideway. The sliding assembly includes two linking rods each slidably mounted between the tracks, two slides each mounted on the linking rods, a plurality of magnet sets mounted on one of the slides and aligning with the electromagnetic device, and two elastic members each biased between one of the slides and the electromagnetic device. Each of the linking rods has two first rollers each mounted in the first slideway and two second rollers mounted in the second slideway. The rocking bed is mounted above the slides. The bottom frame is mounted under the tracks.

Abstract: A baby rocking bed includes a pivot unit, a lower frame connected with the pivot unit, a connecting unit connected with the lower frame, and an upper frame connected with the pivot unit and the connecting unit. Thus, when the movable member of the connecting unit is moved upward on the elbow pipe of the connecting unit, the upper frame is disposed at an inclined state so that the rocking bed is disposed at an inclined state to facilitate the user feeding the baby safely, and when the movable member is moved downward on the elbow pipe, the upper frame is disposed at a horizontal state so that the rocking bed is directly lowered and returned to the original position, without disturbing the sleeping baby.
