Claim:
A sliding guide rail system for slidably opening and closing a drawer, the system comprising a mounting bracket ( 10 ), a fixed guide ( 20 ) mounted on the mounting bracket, an intermediate rail ( 30 ) and a pull-out guide ( 40 ), said fixed and pull-out guides each having a slidably movable housing, a first slidable housing ( 50 ) enabling the intermediate rail to be slidable on said fixed guide ( 20 ) and a second slidable housing ( 50 ′) enabling said pull-out guide to be in turn slidable on said intermediate rail, each of said fixed guide, intermediate rail and pull-out guide having stops ( 60 ) disposed thereon that limit the sliding movement of said first and second slidable housings, wherein a resiliently deformable damping member ( 52 , 52 ′) is located in a respective chamber ( 51 ) provided at each longitudinal end of said first and second slidable housings, the chamber comprising a chamber space ( 51 b ) and a slot ( 51 a ) with said slot disposed at the end of said slidable housing ( 50 , 50 ′), said damping member comprises a generally cylindrical body located within said chamber in said slot ( 51 a ) of said chamber ( 51 ) that retains the damping member, the damping member having a buffer portion that projects out of and beyond its chamber for engaging with a said stop at the travel limit of the slidable housing, said chamber configured to accommodate expansion of said damping member ( 52 , 52 ′) when the damping member is deformed by impact with said stops.
