Drawer adjusting mechanism

Abstract

A drawer adjusting mechanism is able to adjust dimensional errors of a drawer, so that the drawer may be accurately mounted and smoothly slide on two rails of the drawer. The drawer adjusting mechanism includes a drawer bottom level adjusting mechanism adapted to adjust any error in the drawer bottom level caused by errors in the thickness and dimensions of the drawer bottom, a drawer sliding direction adjusting mechanism adapted to adjust any error in the sliding direction of the drawer caused by a drawer front panel not centered at a front end of a drawer box, and a drawer slope adjusting mechanism adapted to adjust any axial slope of the drawer to enable smooth sliding of the drawer along the rails thereof.

1 . A drawer bottom level adjusting mechanism, comprising: 
 a fastening plate provided with a centered through hole;    two bent plates, each of which has an upward peak being in contact with a lower surface of a bottom of a drawer; said two bent plates being connected at respective inner end to two opposite ends of said fastening plate to form two joints, and at respective outer end to a first rail of said drawer; and    a connecting element having a shank and an expanded head; said shank being extended through said central hole on said fastening plate to partially screw into said drawer bottom while said expanded head is abutted on an outer side of said central hole;    whereby when said connecting element is further screwed into said drawer bottom, said expanded head of said connecting element is brought to press against said fastening plate, and said peaks of said two bent plates and said drawer bottom are brought to displace in a direction generally parallel to a normal of said drawer bottom.    
   
   
       2 . The drawer bottom level adjusting mechanism as claimed in  claim 1 , wherein each of said joints of said bent plates and said fastening plate is provided with at least one through hole or notch, so that said joints are easy to bend.  
   
   
       3 . The drawer bottom level adjusting mechanism as claimed in  claim 1 , wherein each of said peaks of said bent plates is provided with at least one through hole or notch, so that said peaks are easy to bend.  
   
   
       4 . The drawer bottom level adjusting mechanism as claimed in  claim 1 , wherein said connecting element is a screw.  
   
   
       5 . A drawer sliding direction adjusting mechanism, comprising: 
 a slide section defining an open-bottom recess, which extends across a full length of said slide section and has an open direction generally parallel to a normal of a bottom of a drawer; said recess being engaged with a second rail of said drawer for said slide section to slide in a movement direction defined by said second rail; and said open direction and said movement direction of said recess being located in the same plane;    a fixing section being fixedly connected to a first rail of said drawer, and having an axial bore provided at a predetermined position on said fixing section;    an elastic connecting section connecting said fixing section to said slide section, and being connected to said fixing section at a joint; and    a push element extended through said axial bore on said fixing section to press against a push block formed on said slide section; said push block and said joint of said fixing section and said elastic connecting section being located at two opposite side of said plane containing said open direction and said movement direction of said recess; whereby when said push element is pressed against said push block of said slide section, an angular displacement of said slide section occurs to cause said first rail to displace relative to said second rail in a direction generally parallel to a bottom of the drawer.    
   
   
       6 . The drawer sliding direction adjusting mechanism as claimed in  claim 5 , wherein said axial bore on said fixing section is internally threaded, and wherein said push element is a screw.  
   
   
       7 . The drawer sliding direction adjusting mechanism as claimed in  claim 5 , wherein said axial bore has an axial centerline generally parallel to said movement direction.  
   
   
       8 . A drawer slope adjusting mechanism, comprising: 
 a supporting plate being provided at a predetermined position with a first through hole, and disposed between a first and a second rail of a drawer, and said first rail being slidable in a movement direction defined by said second rail; and    a push element having a shank and an expanded head; said expanded head being located between said first rail and said supporting plate while said shank being extended through a second through hole provided on said first rail; said expanded head being partially surrounded by said first through hole and being in surface contact with said first through hole at a curved contact surface;    whereby when said push element is adjusted to push said expanded head against said first through hole, said first rail is angularly displaced relative to said second rail in a direction generally parallel to a normal of a bottom of the drawer.    
   
   
       9 . The drawer slope adjusting mechanism as claimed in  claim 8 , wherein said second through hole is internally threaded, and said push element is a screw.
