Description

BACKGROUND OF THE INVENTION

The present invention relates to an armrest, especially to an armrest that includes an armrest pad disposed with a plurality of armrest surfaces. The position of the armrest pad is changed so as to select one of the armrest surfaces for resting users' arms.

For user's comfort, generally chairs are designed with armrests respectively on two sides thereof to rest a forearm or an elbow. There are various designs of the armrests, including height adjustment mechanisms or changes in shape. However, a color, pattern or material of an outer surface of an armrest pad (soft pad in contact with arms) is generally fixed. Take synthetic leather as an example. Foam with specific color and material is set into a mold and a layer of leather is formed on surface during foam molding processes. Thus the color or pattern of the synthetic leather has been determined before molding, and unable to be changed after being molded. This is unable to satisfy respective requirements of various users.

SUMMARY OF THE INVENTION

Therefore it is a primary object of the present invention to provide a multi-surface armrest that includes an armrest pad disposed on a top surface of an armrest support. A lower part of the armrest support is connected to a chair seat. The armrest pad includes a middle part, and a plurality of armrest surfaces arranged around an outer surface of the middle part. The armrest surface allows users to rest their arms. At least one positioning member is arranged between the middle part of the armrest pad and the armrest support. By the positioning member, the armrest pad is operated to be positioned at, assembled with, or separated from the armrest support. While being separated, the armrest pad is moved or rotated to select one of the armrest surfaces to place the arms. Thereby the replacement of the armrest surface is accomplished by simple rotation or movement of the armrest pad.
