Support assembly for a drop leaf

Abstract

A fixed top, for example a top of a dinner table ( 11 ) has a drop leaf ( 12 ) fastened by a hinge ( 13 ). The support assembly for the drop leaf consists of two links, one of which ( 16, 17 ) fastened to the fixed top ( 11 ) and the other ( 20, 21 ) fastened to the drop leaf ( 12 ), which are coupled together by a hinge ( 24 ) so that the links become approximately parallel or form an acute angle together when the drop leaf is swung back to a position approximately parallel with and in back of the fixed top and so that the links form a blunt angle when the extension drop leaf is swung out to extend the fixed top. A releasable locking link ( 26, 27 ) is arranged to lock the links in the position in which the extension drop leaf forms an extension of the fixed top.

1 . A support assembly for a drop leaf fastened by a hinge to a fixed top, characterised by
 two links, one of which fastened to the fixed top and the other fastened to the drop leaf, which are coupled together by a hinge so that the links become approximately parallel or form an acute angle together when the drop leaf is swung back into a position approximately parallel with and in back of the fixed top and so that the links form a blunt angle when the drop leaf is swung out to form an extension of the fixed top, and   a releasable locking device arranged to lock the links in the position where the drop leaf forms an extension of the fixed top.   
   
   
       2 . The support assembly in  claim 1 , characterised in that the locking device is a locking link. 
   
   
       3 . The support assembly in  claim 2 , characterised in that the locking link is coupled between the two hinges. 
   
   
       4 . The support assembly in  claim 3 , characterised in that the locking link comprises a first portion coupled to one of the hinges and a second portion coupled to the other hinge and a latching device to lock the two portions together. 
   
   
       5 . The support assembly in  claim 1  applied on a drop-leaf table. 
   
   
       6 . The support assembly in  claim 2  applied on a drop-leaf table. 
   
   
       7 . The support assembly in  claim 3  applied on a drop-leaf table. 
   
   
       8 . The support assembly in  claim 4  applied on a drop-leaf table.
