20090049605 | PLAYARD - In a playard, the bassinet has adjustors with one ends connecting to a first side of the bassinet body and the other ends to a second side of the bassinet body. The adjustors extend from the first side toward and cross a first side rail of the frame body, reaching to the bottom panel of the frame body and into the frame body, and connecting to the second side of the bassinet body. The playard includes two retainers, each mounting on the second side rail of the frame body. Pulling the adjustors brings the first side and the second side of the bassinet body to move up or down by the same distance. The bassinet can therefore maintain horizontal and be adjusted to an arbitrary height during height adjusting. | 02-26-2009 |
20090049606 | DIAPER CHANGER - Rotation device is configured at the bottom of the body of a diaper changer so that the diaper changer is capable of rotating horizontally relative to the playard frame via the rotation device when mounting thereon. The rotation device includes a rotator and a supporter where the rotator connects to the body and mounts on the supporter for allowing the body to rotate relative to the supporter. The supporter is further configured at one side of the playard frame. The body can also be rotatably mounted on the playard frame by mounted the rotator directly into a shafting hole on the playard frame. With the rotation device, the diaper changer can be selectively set in a first using status for changing a baby's diaper or a second using status for allowing a babysitter for easy holding the baby up. | 02-26-2009 |
20110006572 | Child car seat and elastic crotch belt thereof - A crotch belt assembly for a child car seat comprising a safety belt system and a seat body is provided. The safety belt system is composed of shoulder harnesses provided with a buckle and the crotch belt assembly.
