Publication number: 20100264703Abstract: 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.Type: ApplicationFiled: March 9, 2010Publication date: October 21, 2010Inventors: Shun-Min Chen, Wen-Qu Hu, Xiao-Jian Zhang

Publication number: 20100181806Abstract: Children chair having a height adjusting device and a folding device completes folding up by height adjusting. A first leg frame of the children 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 chair is easy to perform height adjustment and folding movement by simply operating a button at the handle.Type: ApplicationFiled: July 15, 2009Publication date: July 22, 2010Inventors: Jun-Jie Hu, Wen-Qu Hu, Shun-Min Chen

Publication number: 20090315375Abstract: 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.Type: ApplicationFiled: June 17, 2009Publication date: December 24, 2009Inventors: Jun-Jie Hu, Wen-Qu Hu, Zheng-Wen Guo

Publication number: 20090315374Abstract: A child chair includes a seat and a frame. The seat is detachably mounted on the frame by using an engaging assembly. The engaging assembly includes an engaging device and a coupling device. The engaging device is movably mounted on the seat. The coupling device is mounted on the frame and coupled with the engaging device on the seat. The engaging device is cooperated with the coupling device between a locking position and a release position relative to the seat.Type: ApplicationFiled: June 17, 2009Publication date: December 24, 2009Inventors: Jun-Jie Hu, Wen-Qu Hu, Zheng-Wen Guo

Publication number: 20090250977Abstract: 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.Type: ApplicationFiled: April 2, 2009Publication date: October 8, 2009Inventors: Wen-Qu Hu, Shun-Min Chen

Patent number: 7571966Abstract: A removable wheel device includes a wheel unit, a housing, and a locking unit. The wheel unit includes a wheel body and a wheel axle formed with an annular groove. The wheel axle is extendible removably into the housing. The locking unit includes an actuator connected pivotally to the housing, an elastic member mounted between an operating end portion of the actuator and the housing, and a locking pin connected to a force transmitting end portion of the actuator. The operating end portion is depressible to move the force transmitting end portion from a locking position, where the locking pin extends into the annular groove to prevent removal of the wheel axle from the housing, to an unlocking position, where the locking pin is disengaged from the annular groove to permit removal of the wheel axle from the housing.Type: GrantFiled: March 2, 2007Date of Patent: August 11, 2009Assignee: Wonderland Nurserygoods Co., Ltd.Inventors: Shun-Min Chen, Wen-Qu Hu
