Foldable table

Abstract

A foldable table comprises a first table plate having a first frame; a second table plate having a second frame; a combining rod; one end of the combining rod pivoted to the first protruding bar and another end thereof being pivoted to the second protruding bar; the combining rod being a bent structure; thus, the combining rod can drive the first table plate and the second table plate to be expanded toward two sides or be drawn close; a first supporter having a top end pivoted to the first frame; a second supporter having a top end pivoted to the second frame; and a combining frame; two ends of the combining frame being pivoted to the first frame and second frame; the combining frame being installed with a buckling block; a first linkage and a second linkage.

1 . A foldable table, comprising:
 a first table plate having a first frame;   a second table plate having a second frame;   a combining rod; one end of the combining rod pivoted to the first protruding bar and another end thereof being pivoted to the second protruding bar; the combining rod being a bent structure; thus, the combining rod can drive the first table plate and the second table plate to be expanded toward two sides or be drawn close;   a first supporter having a top end pivoted to the first frame;   a second supporter having a top end pivoted to the second frame;   a combining frame; two ends of the combining frame being pivoted to the first frame and second frame; the combining frame being installed with a buckling block;   a first linkage having two ends which are pivoted to the first supporter and the combining frame;   a second linkage having two ends which are pivoted to the second supporter and the combining frame;   a buckling device including a first positioning rod and a second positioning rod; one end of the first positioning rod being pivoted to the first linkage and another end thereof being buckled to the buckling block of the combining frame; one end of the second positioning rod being pivoted to the second linkage and another end being buckled to the buckling block of the combining frame; two ends of the resisting rod resisting against the first positioning rod and the second positioning rod.   
   
   
       2 . The foldable table as claimed in  claim 1 , wherein the first frame is installed with a first protruding bar and the second frame is protruded with a second protruding bar; two ends of the combining rod are pivoted to the first protruding bar and the second protruding bar. 
   
   
       3 . The foldable table as claimed in  claim 1 , wherein the buckling device further includes an operating rod and a resisting rod; wherein the operating rod is pivoted to the combining frame and is connected to the resisting rod so that the operating rod and the resisting rod moves synchronously; two ends of the resisting rod resist against the first positioning rod and the second positioning rod. 
   
   
       4 . The foldable table as claimed in  claim 1 , wherein a first pneumatic rod has one end pivoted to the first linkage and another end thereof is pivoted to the combining frame; a second pneumatic rod has one end pivoted to the second linkage and another end thereof is pivoted to the combining frame. 
   
   
       5 . The foldable table as claimed in  claim 4 , wherein the first pneumatic rod and second pneumatic rod are pivoted to the combining frame. 
   
   
       6 . The foldable table as claimed in  claim 2 , wherein the second protruding bar is an inclined bar with one end fixed to the second table plate and another end points downwards. 
   
   
       7 . The foldable table as claimed in  claim 3 , wherein a long hole is formed in the combining frame so that the operating rod passes out of the long hole. 
   
   
       8 . The foldable table as claimed in  claim 1 , wherein the first supporter is installed with roller and the second supporter is installed with roller. 
   
   
       9 . The foldable table as claimed in  claim 1 , wherein a retainer is used to retain the first table plate and second table plate to be in a drawing close state. 
   
   
       10 . The foldable table as claimed in  claim 9 , wherein the retainer includes a buckling sheet and a buckling block; the buckling sheet is installed with a buckling hole and the buckling sheet is pivoted to the first frame; the buckling block is installed to the second frame; when the first table plate and second table plate are drawn close, the buckling sheet is rotated so that the buckling hole of the buckling sheet can be buckled into the buckling block. 
   
   
       11 . The foldable table as claimed in  claim 10 , wherein the first frame is installed with a buckling block, when the table is expanded, the buckling sheet can buckle the buckling block of the first frame so that it is fixed without vibration.
