Cabinet having drawer locking device

Abstract

A cabinet includes a number of drawers slidably attached to the receptacle which has a track, each drawer includes an actuator having two inclined surfaces and a flat surface, a number of latch members are slidably received in the track of the receptacle and each includes two end inclined surfaces for engaging with the inclined surfaces of the actuators, and a spring biasing device may bias the end protrusions of the latch members to anchor the other drawers to the receptacle, and thus to anchor and lock the other drawers to the receptacle when one of the drawers is pulled and moved out of the receptacle, and to prevent the other drawers from slipping out of the receptacle inadvertently.

1 . A cabinet comprising: 
 a receptacle including a chamber formed therein and defined between two side portions, and including a plurality pairs of lateral drawer guides attached to said side portions thereof respectively, and including a track formed therein and defined between two side walls and an inner wall,    a first drawer and a second drawer each including two side runners slidably attached to said drawer guides of said receptacle, to slidably attach said first and said second drawers to said receptacle, each of said first and said second drawers including an actuator provided thereon and having an upper inclined surface and a lower inclined surface and a flat surface formed therein,    a plurality of latch members slidably received in said track of said receptacle, and each including two end protrusions provided thereon, each of said end protrusions including an inclined surface formed thereon, and arranged for engaging with said inclined surfaces of said actuators, to allow said latch members to be moved up and down along said track of said receptacle by said actuators of said first and said second drawers, and    a spring biasing means for biasing said end protrusions of said latch members to engage with said flat surfaces of the actuators, and to anchor said drawers to said receptacle, and    said inclined surface of said actuator of said first drawer being forced to engage with said inclined surfaces of said latch members and to move said latch members up and down along said track of said receptacle, and to engage said end protrusions of said latch members with said flat surface of said actuator of said second drawer, and thus to anchor said second drawer to said receptacle when said first drawer is pulled and moved out of said receptacle.    
   
   
       2 . The cabinet as claimed in  claim 1  further comprising a third drawer including two side runners slidably attached to said drawer guides of said receptacle, and including an actuator provided thereon and having an upper inclined surface and a lower inclined surface and a flat surface formed therein, said end protrusions of said latch members being forced to engage with said flat surface of said actuator of said third drawer and to anchor said third drawer to said receptacle when said first drawer is pulled and moved out of said receptacle.  
   
   
       3 . The cabinet as claimed in  claim 1 , wherein said spring biasing means includes a block slidably received in said track of said receptacle, and engaged with said latch members, and a spring member engaged between said block and said receptacle, to bias said block to engage with said latch members, and to force said end protrusions of said latch members to engage with said flat surfaces of the actuators.  
   
   
       4 . The cabinet as claimed in  claim 3 , wherein said block includes a slot formed therein, a fastener engaged through said slot of said block, and attached to said receptacle, to slidably secure said block to said track of said receptacle, and to limit said block to move relative to said receptacle.  
   
   
       5 . The cabinet as claimed in  claim 1 , wherein said receptacle includes a stop slidably received in said track thereof, and engaged with said latch members, and includes an oblong hole formed therein, a fastener engaged through said oblong hole of said stop, and attached to said receptacle, to slidably secure said stop to said track of said receptacle, and to limit said stop to move relative to said receptacle.  
   
   
       6 . The cabinet as claimed in  claim 1 , wherein said end protrusions of said latch members each includes a bulge extended upwardly therefrom and having said inclined surface formed thereon.
