Drawer latch

Abstract

A drawer latch includes a controller mounted on an outer side of the drawer. A lever is pivotally mounted on an inner side of a cabinet, which contains the drawer, for selectively engaged to the controller. The lever automatically engaged to the controller to prevent the drawer from an accidentally operated when the drawer is closed.

1 . A drawer latch comprising: 
 a controller adapted to be mounted on an outer side of a drawer, the controller including an axle extending through a front panel of the drawer and an enlarged head formed on one end of the axle, a resilient member sleeved on the axle and having a first end fixed on the axle, a fixing plate adapted to be secured on the outer side of the drawer and corresponding to the axle, the fixing plate having a connecting portion and an engaging portion respectively extending therefrom, a through hole defined in the connecting portion to allow the axle extending through the connecting portion and a second end of the resilient member abutting the connecting portion; and    a lever adapted to be reciprocally and pivotally mounted on an inner side of a cabinet, which contains the drawer, for selectively engaged to the controller, the lever having a shank with a first end pivotally mounted to the inner side of the cabinet and corresponding to the fixing plate, the shank having a second end formed with an inclined side and a hook, a free end of the axle abutting the inclined side and the hook engaged to the engaging portion to prevent the drawer from an accidentally operation when the drawer is closed.    
   
   
       2 . The drawer latch as claimed in  claim 1 , wherein an annular groove is defined in an outer periphery of the axle near the enlarged head and the resilient member is a cone-shaped spring having a first end and a second end, the first end of the resilient member has diameter smaller than that of the second end of the resilient member, the first end of the resilient member engaged to the annular groove in the axle for holding the resilient in place and the second end of the resilient abutting the connecting portion of the fixing plate.  
   
   
       3 . The drawer latch as claimed in  claim 1 , wherein the fixing plate and the connecting portion form an L-shape.  
   
   
       4 . The drawer latch as claimed in  claim 1  further comprising a torsion spring mounted between the shank and the inner side of the cabinet, the torsion spring having a first end adapted to abut against a stopper that extends from the inner side of the cabinet and a second end abutting against the shank for providing a restitution force to the lever.
