Abstract:
A food tray adjustment structure for a high chair located between a chair supported by a high chair frame and a food tray for controlling relative movement and positioning between the chair and the food tray, the chair having armrests on two sides thereof, each armrest having a plurality of indented or jutting sections to form a coupling section, the adjustment structure comprising:a handle located below the food tray and being movable longitudinally and reciprocally, and having a hand grip section for moving and controlling the handle, a pair of longitudinal sections parallel with the armrests each having a biased end which forms a sliding rail with a skew angle from 5 degrees to 45 degrees against a longitudinal direction of the handle; a sliding dock having a latch section engageable with the coupling section and being mounted below the food tray and movable transversely and reciprocally, the sliding dock being coupled with the sliding rail and being driven by the sliding rail to move transversely and reciprocally while the handle is moved reciprocally to allow the latch section to engage with or separate from the coupling section; and a spring pressing the sliding dock towards the coupling section to maintain an elastically latched condition for the adjustment structure; wherein the sliding dock has a coupling trough which has an inner surface with jutting ribs formed thereon to reduce contact area with the sliding rail for reducing friction force.
