Pull-out guide fittings for drawers

Abstract

The invention relates to guide fittings for pulling-out drawers ( 1 ) or the like. The inventive fittings comprise a drawer rail ( 5 ) on the side of the drawer, a support rail ( 3 ) on the side of the body and a central rail ( 6 ) that runs between said two rails ( 3, 5 ) and is situated on both sides of the drawer ( 1 ). The weight of the drawer ( 1 ) is transmitted between the rails ( 3, 5, 6 ) and by means of rollers ( 14 ). A damping device ( 7 ) is active between two of the rails ( 3, 5, 6 ) and comprises at least two components which can be moved in relation to one another.
