Workstation with Powered Height Adjustable Desk

Abstract

A workstation includes a partition unit to form a workspace, in which a desk board, two lifting apparatuses and a driving device are provided. Each of the lifting apparatuses has a first tubular member connected to a bottom of the desk board, a second tubular member fixed to the partition unit, and a lifting device to move the first tubular member relative to the second tubular member. The driving device is connected to the lifting devices to drive the lifting devices to move the first tubular members so as to lift and lower the desk board.

1 . A workstation, comprising:
 a front partition member having a first end and a second end opposite to the first end;   a first wall member and a second wall member connected to the first end and the second end of the front partition member to enclose a workspace;   a desk board provided in the workspace;   two lifting apparatuses connected to the desk board, each of which has a first tubular member, a second tubular member, and a lifting device, wherein the second tubular members are fixed to the first wall member and the second wall member respectively, and each of the first tubular members has an end fitted to the second tubular member and an opposite end connected to the desk board; the lifting device is received in the first and the second tubular members to move the first tubular member relative to the second tubular member; and   a driving device connected to the lifting devices to move the first tubular members through the lifting devices;   wherein the driving device is operated to drive the first tubular members of the lifting apparatuses moving relative to the second tubular members so as to lift and lower the desk board.   
     
     
         2 . The workstation of  claim 1 , wherein at least one of the first wall member and the second wall member is a board. 
     
     
         3 . The workstation of  claim 1 , wherein the driving device has two motors connected to the lifting devices of the lifting apparatuses to drive the lifting devices respectively. 
     
     
         4 . The workstation of  claim 3 , wherein each of the lifting devices has a tube, a nut, and a screw rod; the tube is received in the first and the second tubular members and connected to the second tubular member; the nut is fixed in the tube;
 the screw rod is rotatably connected to the first tubular member and threaded to the nut; the motors of the driving device are connected to the screw rods of the lifting devices to rotate the screw rods respectively.   
     
     
         5 . The workstation of  claim 1 , wherein the driving device has a motor and a transmission device; the motor is connected to both the lifting devices through the transmission device to drive the lifting devices respectively. 
     
     
         6 . The workstation of  claim 5 , wherein the transmission device has a first sector gear, two sector gears, and two shafts; the first sector gear is connected to the motor, and the second sector gears are connected to the lifting devices respectively;
 each of the shafts has a third sector gear and a fourth sector gear at opposite ends thereof; the third sector gears are meshed with the first sector, and the fourth sector gears are meshed with the second sector gears respectively.   
     
     
         7 . The workstation of  claim 6 , wherein each of the lifting apparatuses has a tube, a nut, and a screw rod; the tube is received in the first and the second tubular members and connected to the second tubular member; the nut is fixed in the tube;
 the screw rod is rotatably connected to the first tubular member and threaded to the nut; the second sector gears of the transmission device are connected to the screw rods of the lifting devices.   
     
     
         8 . The workstation of  claim 6 , wherein the transmission device further includes a cover connected to the desk board to cover the shafts. 
     
     
         9 . The workstation of  claim 4 , wherein an end of the screw rod is received in the tube and is suspended, to which a weight member is connected. 
     
     
         10 . The workstation of  claim 7 , wherein an end of the screw rod is received in the tube and is suspended, to which a weight member is connected. 
     
     
         11 . The workstation of  claim 4 , wherein each of the lifting apparatuses further includes a lid is connected to the second tubular member, and the tube has an end connected to the lid. 
     
     
         12 . The workstation of  claim 7 , wherein each of the lifting apparatuses further includes a lid is connected to the second tubular member, and the tube has an end connected to the lid.
