Abstract
Abstract A pull-out guide assembly for drawers is provided by means of which a drawer can be pulled out of a body of a piece of furniture over its entire depth, while still being anchored in the supporting rails on the side of the body. The assembly includes supporting rails on the sides of the body, pull-out rails fastened to the drawer and center rails arranged between the supporting and pull-out rails. Carriages are arranged between the rails, rollers transferring the load from one rail to the other being mounted in the carriages. Locking- and control members are provided to control the course of movement of the individual members of the pull-out guide or to hold the members of the pull-out guide together, when the drawer has been entirely taken out of the body of the piece, thus facilitating the reinsertion of the drawer into the body of the piece of furniture.
