摘要： A vertically adjustable, armrest includes a tubular support constructed for attachment to a chair, an armrest assembly telescopingly positioned in the tubular support, and a height adjustment mechanism slidably received in the armrest assembly. The armrest assembly includes a sleeve and a post. The sleeve includes an opening adapted to receive an operative member on one side. The post includes positional detents extending down the length of a first vertical surface. The height adjustment mechanism includes an actuator rod, an operative member, a locking member, and a resilient member. The actuator rod includes an angled ramp, an inclined surface, and a pair of angled surfaces and the locking member includes teeth which selectively mate with the post detents, an inclined surface, and at least one pair of lateral followers. The actuator rod operatively engages the locking member with the inclined wedge mateably engaged with the inclined surface and the angled surfaces slideably engaged with the lateral followers. To vertically adjust the armrest, the operative member is lifted upward, causing the resilient member to compress and the teeth of the locking member to disengage from the detents. To reengage the teeth with the positional detents, the operative member is released.
摘要翻译：可垂直调节的扶手包括构造成用于附接到椅子的管状支撑件，可伸缩地定位在管状支撑件中的扶手组件和可滑动地容纳在扶手组件中的高度调节机构。扶手组件包括套筒和支柱。套筒包括适于在一侧接收操作构件的开口。该柱包括沿第一垂直表面的长度向下延伸的位置制动。高度调节机构包括致动器杆，操作构件，锁定构件和弹性构件。致动器杆包括成角度的斜面，倾斜表面和一对成角度的表面，并且锁定构件包括选择性地与柱形棘爪，倾斜表面和至少一对侧向从动件配合的齿。致动器杆可操作地接合锁定构件，倾斜的楔形物可与倾斜表面配合接合，并且成角度的表面可与侧向从动件可滑动地接合。为了垂直调节扶手，操作构件被向上提升，导致弹性构件压缩，并且锁定构件的齿与制动爪脱离。为了用位置制动器重新啮合齿，操作构件被释放。
