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
