Table with a foldable tabletop

Abstract

A table has a stand, a tabletop and a positioning device. The stand is composed of two legs pivotally combined together, and each leg has a top. The tabletop is pivotally attached to the tops of the legs and has a first half board and a second half board pivotally connected with each other and pivotally attached respectively to the tops of the legs. The positioning device is mounted between the half boards of the tabletop to hold the tabletop in an expanded condition. Accordingly, the space of the table for storing or transporting can be effectively reduced with the folded tabletop.

1 . A table comprising: 
 a stand composed of two legs pivotally combined together and each leg having a top;    a tabletop pivotally attached to the tops of the legs and comprising a first half board and a second half board pivotally connected with each other and pivotally attached respectively to the tops of the legs; and    a positioning device mounted between the half boards of the tabletop to hold the tabletop in an expanded condition.    
   
   
       2 . The table as claimed in  claim 1 , wherein 
 each one of the first and second half boards has an abutting edge abutting with each other;    the first half board has a concave cutout defined in the abutting edge; and    the second half board has a convex protrusion formed on the abutting edge and extending into the cutout in the first half board.    
   
   
       3 . The table as claimed in  claim 2 , wherein 
 the first half board has multiple pivotal tabs extending toward the second half board;    the second half board has multiple pivotal tabs extending toward the first half board and corresponding respectively to the pivotal tabs on the first half board;    multiple pivots extending respectively through corresponding pivotal tabs on the first and second half board to pivotally connect the first and second half board together.    
   
   
       4 . The table as claimed in  claim 3 , wherein 
 the positioning device comprises    multiple arcuate blocks formed respectively on the pivotal tabs on the first half board; and    multiple engaging fingers formed on the pivotal tabs on the second half board and respectively corresponding to and abutting against the arcuate blocks on the pivotal tabs of the first half board when the tabletop is in the expanded condition.    
   
   
       5 . The table as claimed in  claim 4 , wherein each pivotal tab on the second half board has an arcuate guiding channel corresponding to a corresponding arcuate block on the first half board to hold the corresponding arcuate block inside when the tabletop is in a folded condition.  
   
   
       6 . The table as claimed in  claim 5 , wherein the first half board further has multiple stubs formed on the abutting edge and extending toward the second half board; and 
 the second half board further has multiple positioning holes defined in the abutting edge and corresponding respectively to the stubs on the first half board to hold the stubs inside in respective when the tabletop is in the expanded condition.    
   
   
       7 . The table as claimed in  claim 6 , wherein the first half board further has a supporting tab laterally formed on the abutting edge at the concave cutout to hold the protrusion on the second half board.  
   
   
       8 . The table as claimed in  claim 7 , wherein 
 the second half board has a through hole defined through the second half board near the protrusion; and    a cap detachably held inside the through hole to close the through hole.    
   
   
       9 . The table as claimed in  claim 2 , wherein the first half board further has multiple stubs formed on the abutting edge and extending toward the second half board; and 
 the second half board further has multiple positioning holes defined in the abutting edge and corresponding respectively to the stubs on the first half board to hold the stubs inside respectively when the tabletop is in the expanded condition.    
   
   
       10 . The table as claimed in  claim 9 , wherein the first half board further has a supporting tab laterally formed on the abutting edge at the concave cutout to hold the protrusion on the second half board.  
   
   
       11 . The table as claimed in  claim 10 , wherein 
 the second half board has a through hole defined through the second half board near the protrusion; and    a cap detachably held inside the through hole to close the through hole.    
   
   
       12 . The table as claimed in  claim 1 , wherein 
 the first half board has multiple pivotal tabs extending toward the second half board;    the second half board has multiple pivotal tabs extending toward the first half board and corresponding respectively to the pivotal tabs on the first half board;    multiple pivots extending respectively through corresponding pivotal tabs on the first and second half board to pivotally connect the first and second half board together.    
   
   
       13 . The table as claimed in  claim 12 , wherein 
 the positioning device comprises    multiple arcuate blocks formed respectively on the pivotal tabs on the first half board; and    multiple engaging fingers formed on the pivotal tabs on the second half board and respectively corresponding to and abutting against the arcuate blocks on the pivotal tabs of the first half board when the tabletop is in the expanded condition.    
   
   
       14 . The table as claimed in  claim 13 , wherein each pivotal tab on the second half board has an arcuate guiding channel corresponding to a corresponding arcuate block on the first half board to hold the corresponding arcuate block inside when the tabletop is in a folded condition.  
   
   
       15 . The table as claimed in  claim 1 , wherein 
 each one of the first and second half boards has an abutting edge abutting with each other;    the first half board further has multiple stubs formed on the abutting edge and extending toward the second half board; and    the second half board further has multiple positioning holes defined in the abutting edge and corresponding respectively to the stubs on the first half board to hold the stubs inside respectively when the tabletop is in the expanded condition.    
   
   
       16 . The table as claimed in  claim 2 , wherein the first half board further has a supporting tab laterally formed on the abutting edge at the concave cutout to hold the protrusion on the second half board.  
   
   
       17 . The table as claimed in  claim 2 , wherein 
 the second half board has a through hole defined through the second half board near the protrusion; and    a cap detachably held inside the through hole to close the through hole.
