Drawer pull out guide rail
A drawer guide rail for a stabilized and guided in and out movement of a drawer with respect to the furniture member, having at least one surface of the pull out channel mounted on the bottom surface of the drawer, and a fixed guide ( 20 ) adapted to be fastened on either side or both sides of the inner sidewalls of the respective furniture member. The guide rail assembly includes an outer pull out channel ( 50 ), intermediate pull out channel ( 30 ) and roller units ( 15, 25 ) for allowing the relative movement of the pull out channels. The essential part of the present invention is an additional stabilizer means ( 10 ), in the form of a metal plate adapted to provide a running surface and is disposed between two roller units ( 15, 25 ) accordingly, to facilitate absorbance of vertical forces and stabilized drawer motion.
1. A drawer guide rail assembly mounted for a guided and stabilized in and out movement with respect to a furniture member comprising:
a fixed guide for attachment to an inner sidewall of said furniture member and having at least one running surface;
an intermediate pull out channel capable of sliding back and forth relative to said fixed guide on said running surface of said fixed guide, an upper surface of said intermediate pull out channel section providing a second running surface;
a first roller bearing positioned within said intermediate pull out channel for enabling sliding movement of said intermediate pull out channel on said fixed guide;
an outer pull out channel for attachment to an undersurface of a drawer capable of sliding back and forth on said intermediate pull out channel relative to said intermediate pull out channel; and
a second roller bearing positioned within said outer pull out channel for enabling sliding movement of said outer pull out channel on said intermediate pull out channel, said second roller bearing including roller bodies within a receptacle; wherein said fixed guide running surface is a T-shaped flange extending upwards; said drawer guide rail assembly further comprises a stabilizer positioned between said intermediate pull out channel and said outer pull out channel; said stabilizer is mounted on top of the intermediate pull out channel, and includes a shoulder which is horizontally extended from each side of said stabilizer to be fitted with said second roller bearing for guiding and stabilizing the movements of said outer pull out channel relative to said intermediate pull out channel; and the second roller bearing is disposed over the stabilizer.
2. The drawer guide rail assembly as claimed in claim 1 , wherein said stabilizer is in the form of a metal sheet having inclined sides.
3. The drawer guide rail assembly as claimed in claim 2 , wherein said stabilizer has its width wider than the width of said intermediate pull out channel.
4. The drawer guide rail assembly as claimed in claim 3 , wherein said stabilizer includes a protrusion formed at the upper end of said stabilizer for retaining said second roller bearing in position during movement.
5. The drawer guide rail assembly as claimed in claim 1 , wherein said stabilizer is detachably positioned between said intermediate pull out channel and said outer pull out channel.
