Computer Table That Is Folded and Expanded Easily And Quickly

Abstract

A computer table includes a board assembly including a support board, a movable board pivotally connected with the support board by two elastic fastening members and two connecting members, and two fixing brackets each mounted on the support board and each connected with a respective one of the two elastic fastening members. Thus, the movable board is movable to space from the support board and is movable to abut the support board so that the board assembly is expanded for use with a user and can be folded when not in use to have a smaller volume.

1 . A computer table, comprising:
 a board assembly including:   a support board;   a movable board pivotally connected with the support board by two elastic fastening members and two connecting members; and   two fixing brackets each mounted on the support board and each connected with a respective one of the two elastic fastening members.   
     
     
         2 . The computer table of  claim 1 , wherein
 each of the two fixing brackets of the board assembly has a surface formed with at least one pivot hole and at least one guide slot;   the guide slot of each of the two fixing brackets has a first end formed with a first locking groove and a second end formed with a second locking groove;   each of the two elastic fastening members of the board assembly has a first distal end formed with a bent pivot portion pivotally mounted in the pivot hole of the respective fixing bracket and a second distal end formed with a bent locking portion movably mounted in the guide slot of the respective fixing bracket and releasably locked in the first locking groove or the second locking groove of the guide slot.   
     
     
         3 . The computer table of  claim 1 , wherein each of the two elastic fastening members of the board assembly is pivotally mounted on the movable board by a pivot seat and is detachably locked onto a respective one of the two fixing brackets. 
     
     
         4 . The computer table of  claim 2 , wherein each of the two elastic fastening members of the board assembly has a substantially U-shaped profile. 
     
     
         5 . The computer table of  claim 2 , wherein the guide slot of each of the two fixing brackets has a substantially arc-shaped profile. 
     
     
         6 . The computer table of  claim 2 , wherein the first locking groove of each of the two fixing brackets is inclined relative to the guide slot. 
     
     
         7 . The computer table of  claim 2 , wherein the second locking groove of each of the two fixing brackets is inclined relative to the guide slot. 
     
     
         8 . The computer table of  claim 1 , wherein each of the two connecting members of the board assembly has a first end pivotally connected with the support board and a second end pivotally connected with the movable board. 
     
     
         9 . The computer table of  claim 2 , wherein each of the two elastic fastening members of the board assembly is perpendicular to the support board and the movable board when the locking portion of each of the two elastic fastening members is locked in the second locking groove of the respective fixing bracket so that the movable board is parallel with and spaced from the support board. 
     
     
         10 . The computer table of  claim 2 , wherein each of the two elastic fastening members of the board assembly is parallel with the support board and the movable board when the locking portion of each of the two elastic fastening members is locked in the first locking groove of the respective fixing bracket so that the movable board is movable to abut the support board. 
     
     
         11 . The computer table of  claim 1 , wherein the movable board of the board assembly is disposed under the support board and has a size smaller than that of the support board. 
     
     
         12 . The computer table of  claim 1 , wherein
 the computer table further comprises a frame assembly connected with the board assembly to support the board assembly;   the frame assembly includes a rear frame and two side frames pivotally mounted on two opposite ends of the rear frame respectively;   each of the two opposite ends of the rear frame has an upper portion and a lower portion each provided with a first pivot section;   each of the two side frames has a rear end having an upper portion and a lower portion each provided with a second pivot section pivotally connected with the respective first pivot section of the rear frame by a pivot pin so that the rear end of each of the two side frames is pivotally connected with the rear frame;   each of the two side frames has a front end having an upper portion formed with an elongate locking slot;   the support board of the board assembly is detachably mounted on the rear frame and the two side frames of the frame assembly;   the support board of the board assembly has a front end provided with two locking pieces each inserted into and detachably locked in the locking slot of a respective one of the two side frames to attach the support board of the board assembly to the two side frames of the frame assembly;   the support board of the board assembly has a rear end provided with a threaded locking plate locked onto the rear frame by a threaded locking knob to attach the support board of the board assembly to the rear frame of the frame assembly;   the threaded locking knob is extended through the rear frame and is screwed into the threaded locking plate of the support board.
