- a supporting rail to be mounted on a side of the article of furniture, said supporting rail having a U-shaped guide flange defining a U-shaped channel and having outwardly projecting horizontal marginal flanges on each of opposite sides thereof;
a generally C-shaped pull-out rail embracing said guide flange of said supporting rail, said pull-out rail having on each of opposite sides thereof a generally vertical flange, a lower horizontal flange extending inwardly from a lower end of said vertical flange, and a horizontal running flange extending outwardly from said vertical flange at a position between said lower end thereof and an upper end thereof;
carriage means supporting a plurality rolling means substantially in a horizontal plane for enabling sliding movement between said pull-out rail and said supporting rail, said rolling means comprising central rolling means located in said U-shaped channel and rolling on said U-shaped guide flange and said pull-out rail and lateral rolling means, on each of opposite sides of said central rolling means, and rolling on a respective said lower horizontal flange of said pull-out rail and a respective said horizontal marginal running flange of said guide flange of said supporting rail; and
a drawer rail to be mounted on a drawer and guided for sliding movement relative to said pull-out rail by means of guide means located at each of opposite sides of said drawer rail and slidably engaging both upper and lower surfaces a respective said horizontal running flange at a respective said side of said pull-out rail;

Abstract
A guide rail assembly for a drawer includes, for each side of the drawer, a supporting rail on the side of an article or body of furniture and a pull-out rail slideably mounted on the supporting rail. The load of the drawer is transmitted by means of cylindrical runner rollers and/or balls. The runner rollers or balls are arranged substantially in a horizontal plate and adjacently mounted in carriages. The supporting rail has a guide flange with a U-shaped channel and outwardly projecting horizontal marginal flanges extending from both sides thereof. Central runner rollers roll in the U-shaped channel, and lateral runner rollers roll on the marginal flanges. The pull-out rail embraces the supporting rail. The pull-out rail has on each side thereof an outwardly projecting horizontal running flange which is spaced from the upper and lower edges of the pull-out rail. Balls, runner rollers and/or slides roll on the running flanges of the pull-out rail and carry on each side of the drawer a drawer rail which is fastened thereto.
