Dual functional desk with tilt-adjustable tops

Abstract

A dual functional desk with tilt-adjustable tops includes a stand frame; a front top mounted to an upper front portion of the stand frame via a front tilt control device; and a rear top including a screen support and mounted to an upper rear portion of the stand frame via a rear tilt control device. A computer, TV, or PDA screen may be mounted on the screen support, and the front and the rear top may be separately adjusted to different tilt angles best for writing, reading, or drawing at the front top, or watching the screen mounted on the rear top. When the screen is not in use, the front and the rear top may be simultaneously restored to a horizontal state or adjusted to the same plane with the screen invisibly located below the rear top to increase the usable area on the desk.

       9 . The dual functional desk with tilt-adjustable tops as claimed in  claim 8 , wherein said supporting frame is allowed to move forward or rearward relative to said side members within a range from zero to twenty centimeters.  
   
   
       10 . The dual functional desk with tilt-adjustable tops as claimed in  claim 1 , wherein said stand frame includes two side members provided at two upper lateral sides thereof; and wherein said rear top is pivotally connected at two lower front ends to two near middle points of said two side members via second hinges with said rear tilt control device located between two rear ends of said side members and a position close to a bottom front of said rear top.  
   
   
       11 . The dual functional desk with tilt-adjustable tops as claimed in  claim 1 , wherein said rear tilt control device enables stepped adjustment of a tilt angle of said rear top.  
   
   
       12 . The dual functional desk with tilt-adjustable tops as claimed in  claim 11 , wherein said rear tilt control device enabling stepped adjustment of a tilt angle of said rear top is a positioning ratchet.  
   
   
       13 . The dual functional desk with tilt-adjustable tops as claimed in  claim 1 , wherein said rear tilt control device enables stepless adjustment of a tilt angle of said rear top.  
   
   
       14 . The dual functional desk with tilt-adjustable tops as claimed in  claim 13 , wherein said rear tilt control device enabling stepless adjustment of a tilt angle of said rear top is an air cylinder.  
   
   
       15 . The dual functional desk with tilt-adjustable tops as claimed in  claim 1 , wherein said rear tilt control device enables adjustment of a tilt angle of said rear top within a range from zero to 90 degrees.  
   
   
       16 . The dual functional desk with tilt-adjustable tops as claimed in  claim 1 , wherein said rear top includes a left panel, a right panel, and a screen support located between said left and said right panel; said screen support including: 
 a frame provided at each lateral side with a connecting section, which includes at least one sideward-extended wing plate for connecting to said left or said right panel, and a rearward-extended slotted plate formed of a plurality of horizontally spaced locating slots; and    a fixing bracket including a transverse main body and a forward-extended side plate at each end of said main body; said side plates being provided with fixing holes for aligning with and locking to said locating slots formed on said rearward-extended slotted plates of said connecting sections of said frame; and said main body being provided with at least one screen-fixing hole.
