Cabinet having rails capable of preventing a drawer from falling

Abstract

A cabinet includes a housing, a drawer, two rails, and two engaging members. The housing includes two side walls, a back wall, and a front opening. The drawer has a bottom surface and is disposed between the side walls. Each rail extends in a front-to-rear direction and has a lateral plate portion, a longitudinal top support face, a longitudinal limit face, a front end block, a connecting face, and a rail groove. The engaging members project downwardly from the bottom surface of the drawer in proximity to a rear end of the drawer, and are movable along the connecting face of one of the rails when the drawer slides on the top support face. The engaging members respectively have protrusions that engage the respective front end blocks when the drawer slides to front ends of the rails, thereby limiting the drawer from being released from the housing.

1 . A cabinet comprising:
 a housing including two side walls, a back wall that is connected between said side walls, and a front opening that is formed between said side walls and opposite to said back wall;   a drawer having a bottom surface and disposed between said side walls;   two rails extending in a front-to-rear direction and each having a lateral plate portion that extends longitudinally in the front-to-rear direction and that is fixed in abutment with one of said side walls, a longitudinal top support face that extends transversely from a top end of said lateral plate portion toward said drawer and that is in sliding contact with said bottom surface of said drawer, a longitudinal limit face that extends beneath said top support face and transversely from said lateral plate portion, a front end block that extends downwardly from said top support face and transversely from said lateral plate portion, a connecting face that interconnects said top support face and said limit face, and a rail groove that is bordered by said limit face, said lateral plate portion, and said front end block; and   two engaging members each projecting downwardly from said bottom surface of said drawer in proximity to a rear end of said drawer, and each movable along said connecting face of one of said rails when said drawer slides on said top support face, each of said engaging members having a protrusion that-extends into said rail groove of one of said rails, said protrusion being limited from being moved out of said rail groove by said limit face and said front end block, said drawer engaging said front end block when said drawer slides to front ends of said rails, thereby limiting said drawer from being released from said housing.   
     
     
         2 . The cabinet as claimed in  claim 1 , wherein each of said rails further has a front release hole that extends through said connecting face, said top support face, and said limit face, and that is spatially connected to said rail groove in proximity to said front end block, said protrusion being movable into said rail groove through said front release hole. 
     
     
         3 . The cabinet as claimed in  claim 2 , wherein said protrusion has a circular cross section. 
     
     
         4 . The cabinet as claimed in  claim 2 , wherein said front end block has a stop face that is provided adjacent to said rail groove for engagement with said protrusion. 
     
     
         5 . The cabinet as claimed in  claim 4 , wherein said stop face is a curved face. 
     
     
         6 . The cabinet as claimed in  claim 2 , wherein each of said rails further has a rear end block that extends downwardly from said top support face and transversely from said lateral plate portion and that borders said rail groove, and a rear release hole that extends through said connecting face, said top support face, and said limit face, and that is spatially connected to said rail groove in proximity to said rear end block, said rear end block having a stop face that is adjacent to said rail groove.
