Multi-surface armrest

Abstract

A multi-surface armrest is revealed. The multi-surface armrest 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 consists of a middle part and a plurality of armrest surfaces arranged around an outer surface of the middle part. At least one positioning member is disposed between the armrest pad and the armrest support. The armrest pad is positioned at, assembled with or separated from the armrest support. While the armrest pad and the armrest support are separated, the armrest pad is rotated or moved so as to select one of the armrest surfaces to place arms.

What is claimed is: 
     
         1 . A multi-surface armrest comprising:
 an armrest support whose lower part is connected to a chair seat;   an armrest pad arranged at a top surface of the armrest support and having a middle part; a plurality of armrest surfaces disposed around an outer surface of the middle part and used to place arms; and   a positioning member arranged between the armrest pad and the armrest support; the armrest pad is operated to be positioned at, assembled with or separated from the armrest support by the positioning member; while the armrest pad and the armrest support are separated, the armrest pad is able to be moved for selecting one of the armrest surfaces of the armrest pad to rest arms.   
     
     
         2 . The device as claimed in  claim 1 , wherein an upper surface and a lower surface of the middle part of the armrest pad are respectively disposed with one armrest surface. 
     
     
         3 . The device as claimed in  claim 1 , wherein the plurality of armrest surfaces is made from the same material or made from different materials. 
     
     
         4 . The device as claimed in  claim 1 , wherein a receiving slot is arranged at a top surface of the armrest support; the receiving slot having an opening facing upwards so that the armrest pad passes the opening to be mounted in the receiving slot and one of the armrest surfaces on the armrest pad is exposed to place arms. 
     
     
         5 . The device as claimed in  claim 1 , wherein the positioning member is a connection type so that the armrest pad and the armrest support are not separated from each other completely while the armrest pad is moved out of the top surface of the armrest support. 
     
     
         6 . The device as claimed in  claim 5 , wherein the positioning member includes a main body whose one end is disposed with a first pivot part while the other end is arranged with a second pivot part; a pivot part is disposed on one side of the middle part of the armrest pad and is pivotally connected to the first pivot part of the main body; one side of the armrest support is also arranged with another pivot part that is pivotally connected to the second pivot part of the main body; the armrest pad is pivoted to move into and out of in relation to the armrest support by the positioning member; the armrest pad is also rotated in relation to the positioning member. 
     
     
         7 . The device as claimed in  claim 1 , wherein the positioning member is a separate type so that the armrest pad and the armrest support are separated from each other completely while the armrest pad is moved out of the top surface of the armrest support. 
     
     
         8 . The device as claimed in  claim 7 , wherein the positioning member includes two male fasteners and two female fasteners fastened to each other correspondingly; the two male fasteners are respectively arranged at a front end and a rear end of the armrest support while the two female fasteners are respectively disposed on a front end and a rear end of the middle part of the armrest pad; the male fastener and the female fastener can be operated to be fastened or unfastened with each other. 
     
     
         9 . The device as claimed in  claim 7 , wherein the positioning member includes two sliding rails and two corresponding sliding slots; each sliding rail is sliding in the sliding slot correspondingly; the two sliding rails are respectively arranged at a left side and a right side of the middle part of the armrest pad while the two sliding slots are respectively disposed on an inner left side and an inner right side of the armrest support; the armrest pad is moved out of or moved into the armrest support by the two sliding rails and the two sliding slots. 
     
     
         10 . The device as claimed in  claim 1 , wherein a cross section of the middle part of the armrest pad is triangular so that there are three sides of the middle part and each side is disposed with one armrest surface; thus the armrest pad has three armrest surfaces.
