Computer Table That Is Folded and Expanded Easily and Quickly

Abstract

A computer table includes a frame assembly, a board assembly detachably mounted on the frame assembly, and a shelf detachably mounted on the frame assembly. The frame assembly includes two side frames each pivotally connected with a rear frame. The board assembly includes a plurality of connecting posts each mounted between a support board and a movable board. The shelf includes two connecting brackets each pivotally connected with a support plate and each detachably mounted on a respective one of the two side frames. Thus, the frame assembly, the board assembly and the shelf are detached from each other and are folded individually so that the computer table can be detached and folded to have the minimum volume so as to decrease the cost of packaging, storage and transportation of the computer table.

         5 . The computer table of  claim 4 , wherein when the first locking slot of the at least one first locking plate is locked onto the upper projection of the at least one of the connecting posts, the connecting posts are perpendicular to the support board and the movable board so that the movable board is parallel with and spaced from the support board. 
     
     
         6 . The computer table of  claim 4 , wherein when the second locking slot of the at least one second locking plate is locked onto the lower projection of the at least one of the connecting posts, the connecting posts are rested on the support board so that the movable board movable to abut the support board. 
     
     
         7 . The computer table of  claim 1 , wherein each of the two connecting brackets of the shelf has a first portion pivotally mounted on the support plate by a hinge and a second portion inserted into and locked in the respective side frame of the frame assembly by a threaded locking knob. 
     
     
         8 . The computer table of  claim 7 , wherein each of the two connecting brackets of the shelf has a substantially U-shaped profile. 
     
     
         9 . The computer table of  claim 7 , wherein the threaded locking knob is extended through each of the two side frames of the frame assembly and is screwed into the second portion of each of the two connecting brackets of the shelf. 
     
     
         10 . The computer table of  claim 1 , wherein the computer table further comprises a placing rack removably attached to a side of the support board by two mounting brackets. 
     
     
         11 . The computer table of  claim 10 , wherein each of the two mounting brackets has a substantially U-shaped profile. 
     
     
         12 . The computer table of  claim 10 , wherein each of the two mounting brackets is detachably locked onto the support board of the board assembly by a threaded fastening knob. 
     
     
         13 . The computer table of  claim 10 , wherein the fastening knob is screwed into each of the two mounting brackets and presses the support board of the board assembly. 
     
     
         14 . The computer table of  claim 1 , wherein
 the rear frame of the frame assembly has a mediate portion provided with a housing to receive at least one electric cord;   the frame assembly  1  further includes:   a plurality of hanging hooks mounted in the housing for hanging and winding the electric cord; and   a cover mounted on the housing to cover the hanging hooks and the electric cord.
