Abstract:
1. A sliding guide rail system for slidably opening and closing a drawer within an article of furniture, the system comprising a mounting bracket ( 10 ) for fixing the system to the article of furniture, 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 said slidable housing ( 50 ) enabling said intermediate rail to be slidable on said fixed guide and a second said 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 for limiting 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 ( 51 ) comprises a chamber space ( 51 b ) and a slot ( 51 a ) with said slot disposed at the end of said slidable housing ( 50 , 50 ′), the damping member ( 52 , 52 ′) comprises a body portion ( 52 b , 52 b ′) and a relatively narrower neck portion ( 52 a , 52 a ′) 52 a ′), said body portion being located within said chamber space ( 51 b ) and said narrower neck portion being located in said slot ( 51 a ) of said chamber ( 51 ) so as to retain the damping member, said damping member having a substantially T-shape with a buffer portion that projects out of and beyond its chamber for engaging with said stop at the travel limit of the slidable housing, said chamber being oversized relative to the portion of said damping member disposed within said chamber, said damping member having a loose-fit in said chamber to accommodate widthwise expansion of said damping member when it is deformed by impact with said stop in a lengthwise direction.
