Supporting device and slide rail assembly using the same

Abstract

A slide rail assembly adaptable for support posts which are varying distances apart includes a sliding rail and a supporting device. The supporting device includes a supporting bracket and a sliding bracket. The supporting bracket defines two sliding slots along an extending direction of the supporting bracket, and the sliding bracket defines two sliding portions corresponding to the sliding slot. The sliding bracket is slidably connected to the supporting bracket through the sliding portion and the sliding slot, the sliding bracket is mounted to the sliding rail. A supporting device is also disclosed.

         8 . The supporting device of  claim 3 , wherein the supporting bracket comprises:
 a cover plate;   two third bending portions connected to two opposite sides of the cover plate; and   two second folding edges respectively connected to the two third bending portions;   wherein each of the two third bending portions and a corresponding one of the two second folding edges form a sliding slot; each of two opposite sides of the sliding plate defines the flange slidably connected to the sliding slot.   
     
     
         9 . A slide rail assembly comprising:
 a sliding rail; and   a supporting device comprising:
 a supporting bracket defining two sliding slots along an extending direction of the supporting bracket; and 
 a sliding bracket defining two sliding portions corresponding to the at least one sliding slot; 
   wherein the sliding bracket is slidably connected to the supporting bracket through the sliding portion and the sliding slot; the sliding bracket is mounted to the sliding rail.   
     
     
         10 . The slide rail assembly of  claim 9 , wherein the sliding bracket comprises a sliding plate, each of the sliding portion is a flange connected to a side of the sliding plate. 
     
     
         11 . The slide rail assembly of  claim 10 , wherein the sliding bracket further comprises a first bending portion, the flange is connected to the side of the sliding plate through the first bending portion. 
     
     
         12 . The slide rail assembly of  claim 10 , wherein the sliding plate defines a locking member, the sliding rail defines a locking hole corresponding to the locking member, the sliding bracket is mounted to the sliding rail through the locking member and the locking hole. 
     
     
         13 . The slide rail assembly of  claim 9 , wherein each of the supporting bracket and the sliding bracket comprises a latching unit corresponding to each other; and when the supporting bracket slides along the sliding bracket to a predetermined position, the supporting bracket is latched by the latching unit. 
     
     
         14 . The slide rail assembly of  claim 13 , wherein the latching unit comprises:
 a clamping member defined on the supporting bracket; and   a clamping groove defined on an end of the sliding bracket;   when the supporting bracket slides along the sliding bracket and to a predetermined position protruding out of the sliding bracket, the clamping member is clamped by the clamping groove.   
     
     
         15 . The slide rail assembly of  claim 14 , wherein the latching unit further comprises:
 a first stopping member defined on an end of the supporting bracket; and   a second stopping member defined on the other end of the sliding bracket;   when the supporting bracket slides along the sliding bracket and to a predetermined position aligning with the sliding bracket, the first stopping member is stopped by the second stopping member.   
     
     
         16 . The slide rail assembly of  claim 11 , wherein the supporting bracket comprises:
