Slide rail device

Abstract

A slide rail device includes a first slide rail unit and a second slide rail. The first slide rail unit includes a first slide rail, two support members, and two positioning members. The first slide rail has a sliding surface and two rail walls. The support members abut against the sliding surface, and abut against the rail walls. The positioning members are connected to the sliding surface, are connected to the support members, and retain the support members on the rail walls. The second slide rail is slidably disposed on the sliding surface and abuts against the support members.

What is claimed is: 
     
         1 . A slide rail device comprising:
 a first slide rail unit including
 a first slide rail that has
 a rail plate having a sliding surface, and 
 two rail walls respectively and transversely extending from a top side and a bottom side of said rail plate, 
 
 two support members that abut against said sliding surface, and that respectively abut against said rail walls, and 
 two positioning members that are connected to said sliding surface, that are respectively connected to said support members, and that respectively retain said support members on said rail walls; and 
   a second slide rail slidably disposed on said sliding surface and abutting against said support members.   
     
     
         2 . The slide rail device as claimed in  claim 1 , wherein each of said positioning members has a plate portion and at least one retaining portion that extends from said plate portion and that retains the respective one of said support members on said rail walls. 
     
     
         3 . The slide rail device as claimed in  claim 2 , wherein each of said support members has
 a main portion that abuts against said sliding surface,   at least one contact portion that extends from said main portion along said sliding surface, and   an abutment portion that is connected to said main portion and that abuts against said second slide rail and the respective one of said rail walls.   
     
     
         4 . The slide rail device as claimed in  claim 3 , wherein:
 for each of said support members, a thickness of said at least one contact portion is greater than a thickness of said main portion;   said at least one contact portion of each of said support members has
 a first contact surface, 
 a second contact surface transversely connected to said first contact surface, and 
 a third contact surface transversely connected to said second contact surface and opposite to said first contact surface; 
   said at least one retaining portion of each of said positioning members has
 a first retaining segment connected to said plate portion, and 
 a second retaining segment bent from said first retaining segment; 
   for each of said support members, said first contact surface of said at least one contact portion is disposed for abutting against said plate portion of the respective one of said positioning members, said second contact surface of said at least one contact portion is disposed for abutting against said first retaining segment of said at least one retaining portion of the respective one of said positioning members, and said third contact surface is disposed for abutting against said second retaining segment of said at least one retaining portion of the respective one of said positioning members.   
     
     
         5 . The slide rail device as claimed in  claim 4 , wherein:
 said first slide rail further has at least two mounting holes that are formed in said sliding surface;   said at least one contact portion of each of said support members is inserted into a respective one of said at least two mounting holes; and   said at least one retaining portion of each of said positioning members is inserted into a respective one of said at least two mounting holes.   
     
     
         6 . The slide rail device as claimed in  claim 3 , wherein said abutment portion of each of said support members has an inclined guiding surface that is disposed opposite to the respective one of said rail walls and that abuts against said second slide rail. 
     
     
         7 . The slide rail device as claimed in  claim 3 , wherein said main portion of each of said support members has
 a flat segment that abuts against said sliding surface, and   an angled segment that is transversely connected to said flat segment, that abuts against the respective one of said rail walls, and that is connected to said abutment portion of said support member.
