  • Patent number: 8967710
    Abstract: A folding device is configured at the pivot between the rear leg frame and the front leg frame of a high chair and allows a user to complete folding process by pressing a driving member. When the driving member is pressed, an engaging member of the folding device moves correspondingly to an unlocked position, so that the rear leg frame disengages from and pivots about the front leg frame. The high chair can then be folded easily for the user, and the structure of the invention is simpler than the prior art.

  • Patent number: 8360514
    Abstract: A folding device is configured at the bottom of rear leg frame and at the pivot between the rear leg frame and front leg frame of a high chair. The folding device allows a user to complete folding process by pressing a button at the bottom of the rear leg frame. When the button is pressed, a rotator in the housing of the folding device rotates correspondingly and drags connected steel wires to move horizontally inward. The other ends of the steel wires further connect to engaging parts at the pivots and engaging between the front leg frame and the rear leg frame and retract the engaging parts so that the rear leg frame disengages from and pivots about the front leg frame. The high chair may be folded with one-foot operation.

  • Patent number: 8141943
    Abstract: Children's chair having a height adjusting device and a folding device completes folding up by height adjusting. A first leg frame of the children's chair includes a first upper leg and a first lower leg capable moving relatively. When operating the height adjusting device to adjust the first upper leg relative to the first lower leg, an actuator on the first upper leg pushes a slider of the folding device, which locates at the pivot of the first leg frame and a second leg frame. The slider then interferes with a coupler locating at the second leg frame to disengage from a base mounted on the first leg frame. The second leg frame is then rotatable relative to the first leg frame and may be folded to a folding position. The children's chair is easy to perform height adjustment and folding movement by simply operating a button at the handle.

  • Patent number: 7878584
    Abstract: When a safety belt storage assembly's storage is mounted to a main body of a child seat, the storage of the safety belt storage assembly may be selectively configured between an opened state and a closed state. When the storage of the safety belt storage assembly is configured at the opened state, a safety belt set stored within the housing can be taken out and further used to fasten the child seat to an adult chair. The opened state storage further prevents the child seat from mounting on a frame body. When the safety belt set is stored in the housing, the storage of the safety belt storage assembly can be configured to the closed state and the child seat is allowed to be mounted to the frame body.
