Gear type pull-out table

Abstract

A gear type pull-out table including a table frame, first and second table boards symmetrically disposed on the table frame, an extended table board, and a gear assembly, is provided. The extended table board is disposed between the first and second table boards. The gear assembly is positioned in the table frame, corresponding to the extended table board. The gear assembly includes a first toothed rack fixed to the first table board, a second toothed rack fixed to the second table board, and a gear in synchronous engagement with the first and second toothed racks. The first and second toothed racks are disposed in parallel on two sides of the gear. The first and second table boards are driven to move in opposite directions through the synchronous engagement of the first and second toothed racks and the gear to join or separate the first and second table boards.

We claim: 
     
         1 - 4 . (canceled) 
     
     
         5 : A gear type pull-out table comprising:
 a table frame;   a first table board and a second table board symmetrically disposed on the table frame;   an extended table board disposed between the first table board and the second table board; and   a gear assembly positioned in the table frame, corresponding to the extended table board, wherein the gear assembly comprises:
 a first toothed rack fixed to the first table board; 
 a second toothed rack fixed to the second table board; and 
 a gear in synchronous engagement with the first toothed rack and the second toothed rack, wherein the first toothed rack and the second toothed rack are disposed in parallel on two sides of the gear, and wherein the first table board and the second table board are driven to move in opposite directions through the synchronous engagement of the first toothed rack, the second toothed rack, and the gear to one of join and separate the first table board and the second table board. 
   
     
     
         6 : The gear type pull-out table according to  claim 5 , wherein the gear assembly is fixed to an inner frame of the table frame using a connecting piece. 
     
     
         7 : The gear type pull-out table according to  claim 6 , further comprising:
 a chute disposed on one side of the table frame, proximal to the gear assembly; and   a slider disposed on a bottom surface of each of the first table board and the second table board, wherein the slider is configured to move back and forth along the chute to match the movement of the gear assembly, thereby driving the first table board and the second table board to be one of joined and separated.   
     
     
         8 : The gear type pull-out table according to  claim 5 , wherein the extended table board is configured as a turnover table board comprising a first turnover table board and a second turnover table board, wherein the first turnover table board is connected to the second turnover table board via a central hinge.
