A fully extendable telescopic drawer guide (10; 10′) for furniture components, such as drawers, work surfaces and the like, that can be extended from the body of an item of furniture, with a guide rail (12) facing the body, a running rail (14) associated with the extendable furniture componen
A fully extendable telescopic drawer guide (10; 10′) for furniture components, such as drawers, work surfaces and the like, that can be extended from the body of an item of furniture, with a guide rail (12) facing the body, a running rail (14) associated with the extendable furniture component, and an intermediate rail (16) arranged between these two rails, wherein rolling elements are provided which are supported in cages (24; 26) and which transfer the load of the extendable furniture component by way of rolling surfaces disposed on the rails, and wherein at least one rotatably supported supporting roller (30) for the running rail is provided on the front end of the intermediate rail. The intermediate rail (16) is implemented as a profile rail which encompasses the region of the guide rail (12) provided with the rolling surfaces and which has on the bottom side an elongated opening for insertion of the support region of the guide rail to be secured to the body wall of an associated item of furniture. The intermediate rail (16) further includes inner rolling surfaces for the rolling elements that face the rolling surfaces of the guide rail (12). The running rail is also formed as a profile rail which also has on the bottom side an elongated opening and encompasses the intermediate rail. Two supporting rollers (30) are supported on the front end of the intermediate rail on axles that protrude horizontally from the opposing lateral profile legs of the intermediate rail (16) perpendicular to the pull-out direction, with the peripheral surfaces of the supporting rollers being supported on rolling surfaces disposed on the interior of the running rail (14) and extending in the pull-out direction.

The invention claimed is: 1. A fully extendable telescopic drawer guide for furniture components that can be extended from a body of an item of furniture, the fully extendable telescopic drawer guide comprising a guide rail adapted to face the body, a running rail associated with the furniture component, and an intermediate rail arranged between the guide rail and the running rail, wherein rolling elements are provided which are supported in cages and are adapted to transfer a load of the furniture component by way of rolling surfaces disposed on the guide rail, the running rail and the intermediate rail, wherein at least one rotatably supported supporting roller for the running rail is provided on a front end of the intermediate rail, wherein the intermediate rail is implemented as a profile rail which encompasses a region of the guide rail having the rolling surfaces and which has, on a bottom side, an elongated opening for insertion of a support region of the guide rail to be secured to a body wall of the item of furniture, wherein the intermediate rail comprises inner rolling surfaces for the rolling elements that face the rolling surfaces of the guide rail, wherein the running rail is implemented as a profile rail which has, on a bottom side, an elongated opening and encompasses the intermediate rail, whereby two supporting rollers are supported on the front end of the intermediate rail on axles that protrude horizontally from opposing lateral profile legs of the intermediate rail perpendicular to a pull-out direction, with peripheral surfaces of the supporting rollers being supported on rolling surfaces arranged on an interior of the running rail and extending in the pull-out direction, wherein the axles which rotatably support the supporting rollers are provided on a separate axle support that can be attached to the front end of the intermediate rail, wherein the axle support has the form of a retaining member which fittingly encompasses the outer sides of the intermediate rail and which is open on the bottom side, wherein the retaining member has a cross-sectional shape which resembles a “U” rotated by 180° and which is open on the bottom side, wherein the downward pointing lateral U-shaped legs of the retaining member can be brought into suitable contact with the lateral profile legs of the intermediate rail, and further wherein latchingly engageable projections and openings are provided in the regions of the U-shaped legs of the retaining member and the lateral profile legs that face one another in the intended installation position of the axle support on the intermediate rail. 2. Drawer guide according to claim 1, wherein the projections protrude from the inner sides of the U-shaped leg of the retaining member and engage in the openings which are formed as punched-out sections in the profile legs of the intermediate rail. 3. Drawer guide according to claim 2, wherein the projections are provided with beveled stop sections which facilitate installation of the retaining member attached on the intermediate rail from the web surface. 4. Drawer guide according to claim 1, wherein a web section of the retaining member connecting the U-shaped legs is formed so as to be elastically deformable in a center region extending in the pull-out direction.
