    • An adjustable arm rest assembly for use on a chair including a support member, an arm rest member, a locking element and an adjustment member. The support member is attached to the chair and extends substantially upward therefrom. The arm rest member extends substantially coaxially with the support member. The locking element is attached to one of the support member and the arm rest member. A projecting portion extends from an end portion of the locking element and includes a first mating element. The adjustment member is attached to the other of the support member and the arm rest member. The adjustment member and the locking element are movable with respect to one another. A plurality of vertically spaced flanges form a plurality of recesses within the adjustment member. Each recess is sized to receive the projecting portion of the locking element and has a second mating element corresponding to the first mating element. The arm rest member is angularly movable when the first and second mating elements are disengaged. The arm rest member is also angularly and vertically movable when the first and second mating elements are disengaged and the projecting portion of the locking element is disengaged from the recess of the adjustment member.
    • 一种用于椅子上的可调式扶手组件,包括支撑构件,扶手构件,锁定元件和调节构件。 支撑构件附接到椅子并且基本向上延伸。 扶手构件与支撑构件大致同轴地延伸。 锁定元件附接到支撑构件和扶手构件中的一个。 突出部分从锁定元件的端部延伸并且包括第一配合元件。 调节构件附接到支撑构件和扶手构件中的另一个。 调节构件和锁定元件可相对于彼此移动。 多个垂直间隔的凸缘在调节构件内形成多个凹部。 每个凹部的尺寸设置成接收锁定元件的突出部分,并且具有对应于第一配合元件的第二配合元件。 当第一和第二配合元件脱离时,扶手构件可成角度地移动。 当第一和第二配合元件脱离并且锁定元件的突出部分与调节构件的凹部脱离时,扶手构件也可成角度地和垂直地移动。
