HEIGHT-ADJUSTABLE CHAIR ARM ASSEMBLY |
摘要 |
An arm assembly (21) on a chair (11) includes an armrest (22) which adjacent one end is connected to an upper end of a support column (23). The support column is axially slidably supported within an elongate support tube (61) which projects downwardly adjacent a side of the chair seat (14). The support column and support tube have a cooperating linear anti-friction bearing arrangement (71) therebetween, the latter incorporating a resilient support track (77) to eliminate circumferential clearance. A latch member (82) is carried on the column and cooperates with a plurality of latch-receiving slots (85) formed in the support tube. The latch member is activated by a push rod (91) which projects upwardly through the support column, and at its upper end is activated by a lever (93) which terminates in a button (96) adjacent the front of the armrest. |
