Thus, the control unit831does not rotate and the child chair apparatus100can be the rocking chair.

Please refer toFIG. 11toFIG. 14. Working procedure of the child chair apparatus100is introduced as following description.

As shown inFIG. 11, the front foot11and the rear foot12are unfolded to support the fixing component2. The seat component3is disposed between the fixing components2. One of the engaging holes411on the back adjusting component41is capable of being engaged with the engaging member23of the fixing component2. The constraining component7inserts into the oscillating slot341to contact against the first shaft21at an end of the oscillating slot341, so as to constrain the slide of the first shaft21relative to the oscillating slot341. At the time, the child chair apparatus100can be the high chair, and the seat component3can be fixed on the fixing component2at the specific inclined angle. A constraint portion51is disposed on a bottom of the tray5. When the child chair apparatus100is utilized as the high chair, the control unit831can not rotate upwardly to prevent the interference. For adjusting the angle of the seat component3, the operational component441of the handle44can be pulled, and the handle44slides relative to the back of the seat component3upwardly. The first cable43is driven by the handle44to move the back adjusting component41into the accommodating slot33, and the first resilient component42is compressed. Meanwhile, the engaging hole411is separated from the engaging member23, the seat component3can rotate relative to the first shaft21, which means that the seat component3can rotate relative to the fixing component2, and the second sliding slot322slides relative to the second shaft22to adjust the angle of the seat component3. Angle adjustment of the seat component3corresponds to position of the engaging holes411on the back adjusting component41. Three engaging holes411are designed in the present invention. The seat component3can be adjusted at different angles according user's demand. As the angle adjustment is finished, the engaging hole411on the back adjusting component41aligns with the engaging member23, the operational component441is released and the handle44moves downwardly. The resilient force of the first resilient component42moves the back adjusting component41to be close to the fixing component2, so the engaging hole411is engaged with the engaging member23and the seat component3is fixed on the fixing component2. After the angle adjustment, the seat component3can be fixed on the fixing component2at the other inclined angle. When the engaging member23is engaged with the upper engaging hole411, the constraining component7constrains a movement of the first shaft21relative to the oscillating slot341, and the seat component3can be kept at the specific inclined angle.

As shown inFIG. 12toFIG. 14, the handle44can be pulled to switch the child chair apparatus100from the high chair to the rocking chair. The angle of the seat component3is adjustable when the engaging hole441on the back adjusting component41is separated from the engaging member23.

At the time, the recovering spring833is compressed by the safety button832, the other end of the safety button832moves away from the positioning hole835on the front end of the positioning portion834. The control unit831is manually driven to rotate relative to the center of the positioning portion834from the low side to the upper side. Further, the control unit831pulls the second cable82, the second cable82surrounds the positioning portion834to move the constraining component7, and the constraining component7can be separated from the oscillating slot341. The second resilient component81is compressed when the constraining component7is separated from the oscillating slot341. Meanwhile, the first shaft21is unlocked inside the oscillating slot341, so the first shaft21can slide relative to the oscillating slot341. Then, the safety button832is released. The other end of the safety button832inserts into the positioning hole835on the rear end of the positioning portion834by the resilient force of the recovering spring833, so as to fix the control unit831. The first sliding slot321and the oscillating slot341on the seat component3respectively slide relative to the second shaft22and the first shaft21, the engaging member23can be capable of sliding inside the track slot412without interference, so that the seat component3be oscillatory, which means the child chair apparatus100is switched to be the rocking chair. For fixing the seat component3, the first shaft21slides to an initial position, and the safety button832is pushed. The control unit831rotates downwardly to release the second cable82, the second resilient component81utilizes the resilient recovering force to move the constraining component7into the oscillating slot341, the slide of the first shaft21is constrained by the constraining component7, and the seat component3can be fixed without oscillation.

The back adjusting mechanism4is disposed between the seat component3and the fixing component2. The second sliding slot322is formed on the adjusting base32, the second shaft22is slidably disposed inside the second sliding slot32, and the first shaft21is pivotally connected to the front of the seat component3. The first cable43is utilized to separate the back adjusting component41from the fixing component2, so that the second shaft22slides inside the second sliding slot322and the seat component3can rotate relative to the first shaft21for position adjustment. Besides, the resilient recovering force of the first resilient component42can be utilized to engage the back adjusting component41with the fixing component2automatically when the position adjustment of the seat component3is finished, so as to fix the position of the seat component3. Further, due to the first sliding slot321formed on the adjusting base32and the oscillating slot341formed on the oscillating base34, the control mechanism8controls the constraining component7to move in and to move out of the oscillating slot341, so as to lock and unlock the first shaft21. Thus, the seat component3can slide relative to the first shaft21and the second shaft22for oscillation. The present invention has advantages of easy operation and convenient usage. The angle of the seat component3is adjusted by pulling the first cable43, and the child chair apparatus100can be switched from the high chair to the rocking chair.
