摘要： A chair adjustment mechanism has a pin retaining member (as, for example, a sleeve) with a slot having two laterally spaced pin receptors. Each receptor is partially defined by a peripheral wall of the slot and is further defined by a spring finger that projects along side of the peripheral wall. With this arrangement, a pin may be received through the slot and into a longitudinal slot of a second member (as, for example, a J-bar), which longitudinal slot defines a rack. The pin receptors may be positioned such that with the pin in a first of the pin receptors, it is engaged by the rack. In consequence, the pin retaining member may be moved upwardly with respect to the second member by notching the pin over teeth of the rack against the urging of the spring finger. The top of the longitudinal slot may have a cam surface to cam the pin into the second pin receptor such that the pin is now spaced from the rack. This releases the pin retaining member to be lowered with respect to the second member. The longitudinal slot may have a second cam surface proximate its bottom end to again cam the pin into the rack.

摘要翻译： 椅子调节机构具有销保持构件（例如，套筒），其具有具有两个横向间隔开的销接收器的狭槽。 每个接收器部分地由狭槽的周边壁限定，并且由沿着周壁的侧面突出的弹簧指限定。 通过这种布置，销可以通过狭槽被接纳到第二构件（例如，J形杆）的纵向狭槽中，该纵向狭槽限定了支架。 引脚接收器可以被定位成使得在第一引脚接收器中的引脚被引脚接合。 因此，销保持构件可以相对于第二构件向上移动，以克服弹簧手指的推动而将销钉卡在齿条的齿上。 纵向槽的顶部可以具有凸轮表面，以将销凸轮入第二销接收器，使得销现在与齿条间隔开。 这样就释放相对于第二构件降低的销保持构件。 纵向槽可以具有靠近其底端的第二凸轮表面，以将销钉再次凸起到齿条中。

摘要： A chair height adjustment mechanism includes a lever positioned to overlay a valve opening member of a height adjusting cylinder. The lever may be depressed by a cam on a control arm when the control arm is rotated. The depressed lever then depresses the valve opening member. Depression of the lever through the rotation of the control arm may give finer control to the depression of the valve opening member than is conventional.
