DETAILED DESCRIPTION OF THE INVENTION

(12) A pull-out guide 1 according to the present invention comprises a cabinet rail 2 and, mounted movably relative to the cabinet rail 2, a drawer rail 3 (FIGS. 1 and 2). The pull-out guide 1 is designed, for example, as a face-frame pull-out guide. Moreover, the pull-out guide 1 can have a retraction mechanism 4, which is arranged on the cabinet rail 2 in such a way that, in a closure movement of the drawer rail 3, it couples onto a catch of the drawer rail 3 and moves the drawer rail 3 from a partially closed position to a fully closed position relative to the cabinet rail 2. The retraction mechanism 4 comprises, inter alia, a force accumulator 35 and a coupling element 36 (FIG. 10). The force accumulator 35 comprises, for example, a cylinder in which a connecting rod can execute a linear lifting movement. The coupling element 36 is present, for example, at one end of the connecting rod.

(13) At a front end area 5 of the cabinet rail 2, a bearing member 6 is bent out in a tongue shape on the cabinet rail 2. The bearing member 6 is, for example, U-shaped in cross section, in particular, perpendicular to a direction of movement S of the drawer rail 3. In this way, the bearing member 6 is dimensionally stable (FIGS. 4 and 5).

(14) The bearing member 6 comprises a support face 7 which has a support position 8 on which a bearing roller 9 of a support element 10 stands and/or rests and/or supports when the drawer rail 3 is located in a fully opened position relative to the cabinet rail 2 (FIG. 2).

(15) The support face 7 of the bearing member 6 is parallel to the direction of movement S of the drawer rail 3 and parallel to a guide face 11 on the cabinet rail 2.

(16) Moreover, the bearing member 6 comprises a ramp 12 which protrudes from the bearing member 6 parallel to the direction of movement S of the drawer rail 3 in the direction of a rear end area 13 of the pull-out guide 1. The ramp 6 is shaped like a flag and has a downward curvature away from the drawer rail 3. In this way, in an opening movement of the drawer rail 3 relative to the cabinet rail 2, the bearing roller 9 of the support element 10 can roll onto the support face 7 as it were free from obstruction, e.g. without having to overcome an edge or step, in the direction of the support position 8.

(17) The support element 10 is designed as a sheet-metal part bent in an L shape and, for example, riveted and/or welded onto the drawer rail 3 (FIGS. 2 and 5). On an underside 14 of the support element 10, the bearing roller 9 is mounted rotatably on the support element 10 via a rotation axle 15. In the state with the support element 10 arranged on the drawer rail 3, the rotation axle 15 is perpendicular to a direction of movement S of the drawer rail 3 and parallel to a support face 7 of the bearing member 6.

(18) The support element 10 is, in particular, formed on the drawer rail 3 in such a way that vertical forces which act on the drawer rail 3, perpendicular to the direction of movement S of the drawer rail 3, are transferred via the support element 10 to the bearing member 6 and thus to the cabinet rail 2. In this way, the pull-out guide 1, in the fully opened state of the pull-out guide 1, can absorb or take up quite considerable vertical forces without the pull-out guide 1 being damaged.

(19) Advantageously, the bearing member 6 and the support element 10 are arranged on the cabinet rail 2 and on the drawer rail 3 in such a way that, particularly, when the pull-out guide 1 is designed as a base-mounted pull-out guide, an overall height H of the pull-out guide 1 is not increased by the bearing member 6 and the support element 10. For example, the bearing member 6 and the support element 10 protrude laterally on the cabinet rail 2 and the drawer rail 3.

(20) The drawer rail 3 is supported movably on the cabinet rail 2 by means of a roller carriage 16. The roller carriage 16 rolls with rollers on guide faces 11, 17, 18 of the cabinet rail 2. The guide faces 17 and 18 serve here for the lateral guiding of the roller carriage 16 on the cabinet rail 2 (FIGS. 6 and 7).

(21) The roller carriage 16 comprises a cage 19 in which the rollers of the roller carriage 16 are mounted movably. The cage 19 is U-shaped in cross section or helical, such that, in the arranged state on the cabinet rail 2, it engages, for example, around an L-shaped edge 20 of the cabinet rail 2 on which the guide faces 11, 17, 18 are formed.

(22) Latch elements 23, 24 protruding in the shape of cylinders are present on mutually opposite outsides 21, 22 of the roller carriage 16. Advantageously, bearing faces 25, 26 of the latch elements 23, 24 protrude from the cage 19 of the roller carriage 16 in such a way that lateral movement play of an arranged drawer rail 3 is avoided.

(23) It is conceivable that the bearing faces 25, 26 of the latch elements 23, 24 each form, with roll faces 27, 28, 29 of rollers 30, 31, 32 of the roller carriage 16, a plane for resting on guide faces of the drawer rail 3. It is also possible to imagine that, in the state with the roller carriage 16 arranged on the cabinet rail 2, the bearing faces 25, 26 of the latch elements 23, 24 protrude farther from the guide faces 17, 18 than the roll faces 27, 28, 29 of the rollers 30, 31, 32 (FIGS. 8 and 9). The reverse is also conceivable, where the roll faces 27, 28, 29 of the rollers 30, 31, 32 protrude farther from the guide faces 17, 18 than the bearing faces 25, 26 of the latch elements 23, 24.

(24) It is also advantageous that the latch elements 23, 24 are present lying diagonally opposite each other on outsides 21, 22 of the roller carriage 16. The latch element 23 is formed on the cage 19 of the roller carriage 16 in such a way that it does not touch the guide face 18 of the cabinet rail 2. The latch element 23 is spaced apart from the guide face 18. A recess 34 is provided between a top 33 and the latch element 23 of the cage 19; in this way the latch element 23 is present elastically, e.g. resiliently, on the cage 19 (FIG. 9).

(25) A stop element 37 is bent out like a flag on the cabinet rail 2. An abutment element 38 is arranged on the drawer rail 3 and abuts against the stop element 37 during a closure movement of the drawer rail 3 relative to the cabinet rail 2. In the state with the abutment element 38 bearing on the stop element 37, the force accumulator 35 of the automatic retraction mechanism 4 of the pull-out guide 1 is in this way advantageously maintained under prestressing (FIG. 10).

(26) FIGS. 12 and 13 show a pull-out guide 39 according to the present invention in the form of a full-extension pull-out, consisting of a cabinet rail 40, a central rail 41 and a drawer rail 42.

(27) FIG. 14 shows an item of furniture 43 consisting, inter alia, of a furniture rear wall 44, a furniture side wall 45 and furniture front struts 46, 47. A pull-out guide 1 is arranged on the item of furniture 43. The pull-out guide 1 is mounted, in a rear area 13, onto the furniture rear wall 44 and, in an opposite front area 5, is secured on and rests on the furniture front strut 47 and is secured on the furniture front strut 46.
