Embodiment Construction

[0021]FIG. 3 is an exploded view of an adjustable armrest assembly 100 according to one embodiment of the present invention. The armrest assembly 100 comprises a supporting tube 102, a height control member 104 and a housing 106. The supporting tube 102 is fixed on one side of a chair (not shown) and defines a chamber 108 for receiving the height control member 104. The height control member 104 is slidably engaged along the chamber 108 of the supporting tube 102. The housing 106 houses the supporting tube 102 and the height control member 104, and has an opening 109a and an opening 109b respectively formed on two opposite sides. In addition, the housing 106 and the height control member 104 are slidable together relative to the supporting tube 102. The supporting tube 102 has a guiding frame 110 fixed on the inner wall 108a of the chamber 108 for guiding the height control member 104 into the chamber 108. The guiding frame 110 has a plurality of positioning grooves 112 arranged in ...

Abstract

An adjustable armrest assembly comprises a supporting tube having a chamber and a plurality of positioning grooves formed within the chamber, and a height control member slidably engaged along the chamber of the supporting tube; the height control member is connected to a armrest and provided with a positioning block, wherein the positioning block can be selectively driven to disengage from or engage with any one of the positioning grooves such that the armrest can be adjusted and fixed to a desirable height.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention generally relates to an armrest assembly, and more particularly to an adjustable armrest assembly. [0003] 2. Description of the Related Art [0004]FIGS. 1 and 2 show a conventional adjustable armrest assembly 10. The adjustable armrest assembly 10 comprises an L-shaped supporting member 12, a vertical sleeve 14, a lever body 16, and an armrest 18. [0005] The L-shaped supporting member 12 has a horizontal part 20 fixed on a chair (not shown), and a vertical part 22 extending upward from the proximal end of the horizontal part 20 and having a plurality of positioning grooves 24 formed thereon. The vertical sleeve 14 is slidably sleeved on the vertical part 22 and defines a space 26 for receiving the vertical part 22. The vertical sleeve 14 has a plurality of limiting ribs 28 formed within the space 26, and the limiting ribs 28 slidably contact the vertical part 22 so as to prevent wobbling of the vertica...
