Abstract
A mechanism for modulating the height of a chair for a small child which is designed such that it can be easily manipulated to adjust the height, and substantially all of the moving parts of the mechanism are enclosed. The chair, having the leg height modulation mechanism, includes a pair of leg assemblies of adjustable height, and a body coupled thereto in a pivotable manner. The front and rear legs of each of the leg assemblies are crossed and pivotally coupled to each other at their midportions. The front leg of each assembly is pivotally coupled at its upper end to a forward end of a support member by a pin. The rear leg is pivotally coupled at its upper end to a rear end of a slider. The slider is fitted in a holder so that the slider can be caused to slide while being guided by a sliding guide opening of the holder. The holder has a nearly U-shaped cross section, and is secured in the support member. The lower end of the engagement pin of a stopper secured to the top of the holder is engaged in a selected one of fitting holes provided in the upper portion of the slider at prescribed intervals in the longitudinal direction thereof.
