    专利说明:

    The present invention relates to a drawer assembly comprising: a drawer side wall connected or connectable to a drawer rail of a drawer extension guide, the drawer side wall having a support for supporting a drawer bottom, a drawer extension guide having a cabinet rail to be fixed to a furniture body with the drawer side wall connected or connectable drawer rail and a center rail, which is movably mounted between the carcass rail and the drawer rail, wherein the middle rail has a side web and a crosspiece connected thereto, wherein the side web of the center rail in mounting position at least partially laterally next to the support for the drawer bottom is arranged.
    Furthermore, the invention relates to a drawer with an arrangement of the type to be described.
    In DE 103 17 311 A1 a drawer extension guide in the form of a full extension and a drawer side wall is shown in Figure 1, wherein a vertical main leg of the center rail is arranged laterally next to a support leg for a drawer bottom. To increase the lateral stability of the drawer extension guide, the middle rail can, as shown in FIG. 7, comprise an asymmetrical, extended transverse web which projects at right angles from the main leg. Although this measure brings about an improvement in the lateral stability of the drawer pull-out guide, a considerable lateral tilting moment is nevertheless exerted on the drawer pull-out guide when the drawer bottom is heavily loaded. Another disadvantage is that a relatively large space is provided for this construction.
    Object of the present invention is to provide a drawer assembly of the type mentioned above with a more compact design and with a higher stability.
    This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.
    According to the invention it is thus provided that the transverse web of the center rail protrudes at least in sections in the mounting position under the support for the drawer bottom.
    By located at least partially below the support leg crosspiece of the middle rail, the weight of the drawer can be introduced in the mounting position with a smaller lateral effective distance in the center rail, which - especially at heavy loading of the drawer - a lower tilting moment is exerted on the drawer extension. A force introduced by the weight of the drawer is thereby introduced closer to an imaginary vertical direction and in a position very close relative to the furniture body, so that the vertical rigidity of the drawer extension guide is improved. In this way, the rolling elements of carriages, which are movably mounted between the carcass rail and the center rail and / or between the center rail and the drawer rail, more uniformly loaded in the vertical direction and are therefore exposed to lower one-sided loads (which can lead to undesirable deformations) ,
    Another advantage of the invention is that the drawer bottom can be brought closer to the drawer pull-out, so that a wider drawer bottom with an increased surface for storage material is used.
    For improved absorption of vertical forces of the side bar of the middle rail may be formed longer than the crosspiece. The ratio of the height of the side bar to the width of the cross bar may be between 1 to 0.4 and 1 to 1, preferably between 1 to 0.5 and 1 to 0.7.
    The side web and the transverse web can be integrally formed together, for example in such a way that the side web and the transverse web together form an L-shape with two substantially mutually perpendicular webs.
    To increase the torsional stiffness of the side bar may have at least one stiffening groove which extends at least in sections in a longitudinal direction of the center rail, wherein the stiffening groove is arranged approximately halfway up the side web in mounting position.
    For additional improvement of the tilting security of the drawer extension guide, the transverse web can have a free end region, which is supported by at least one rolling element with respect to the carcass rail. This rolling element can be arranged in a carriage, which is at least partially movable along the transverse web in the longitudinal direction of the middle rail.
    The drawer according to the invention is characterized by an arrangement of the type described.
    Further details and advantages of the present invention will be explained with reference to the following description of the figures. It shows or show:
    1 is a perspective view of a piece of furniture with a furniture body and relatively movably mounted drawers,

The fastening sections 12a, 12b connected to the carcass rail 9 have one or more fastening points 13, 14 for fastening to the furniture carcass 2. Between the drawer rail 10 and the carcass rail 9 a movable center rail 11 is arranged, wherein on the drawer rail 10, a coupling element 21 is arranged, which is releasably coupled to a driver 20 of a feed device 18, so that the drawer rail 10 detected by the driver 20 towards the end of the closing movement and is retractable by a power storage of the feeder 18 in a closed end position. By a damping device 19, preferably with a hydraulic piston-cylinder unit, this spring-assisted retraction movement of the drawer rail 10 can be braked down to the closed end position. In the front end region of the drawer rail 10 at least one support roller 22 is mounted, which supports the drawer rail 10 in the closed end position relative to the carcass rail 9, so that a lowering of the front panel 5 is prevented relative to the furniture body 2.
    The drawer side wall 7 is formed as a hollow chamber profile with an inner profile wall 7a and an outer profile wall 7b, wherein the drawer side wall 7 forms a downwardly open and extending in the longitudinal direction of the drawer side wall 7 channel 17, in which the drawer rail 10 can be arranged. The drawer side wall 7 further comprises a first fastening device 15a for connecting to the rear wall 8, a second fastening device 15b for connecting to the front panel 5 and a support 16 for supporting the
    Drawer bottom 6 on. The support 16 may be formed, for example, by an L-shaped web of the drawer side wall 7.
    Fig. 3 shows the drawer pull-4 in an exploded view. At the front end region of the carcass rail 9, an elevation 23 is formed, which cooperates in the closed end position of the drawer rail 10 with the support roller 22 arranged thereon and thus keeps the front panel 5 in a predetermined height position when the drawer 3 is closed. In a recess 29a of the center rail 11, a gear 29 for synchronizing a relative movement between the center rail 11 and drawer rail 10 is rotatably mounted, wherein the gear 29 cooperates with a toothing 36 of a first carriage 35. This first carriage 35 is displaceably mounted between the middle rail 11 and the drawer rail 10 and has rolling elements 37 which are rollable along a catwalk 34 of the middle rail 11, wherein the catwalk 34 from a side web 30 of the middle rail 11 transversely, preferably substantially at right angles, projects. Moreover, a second carriage 24 is provided which is slidably mounted between the carcass rail 9 and the center rail 11. This second carriage 24 also has a toothing 28 which cooperates with the gear 29 of the center rail 11. This second carriage 24 has two spaced apart in the longitudinal direction of rolling elements with rolling elements 25, 26, 27, wherein the rolling elements 25, 27 each have a vertically extending axis of rotation and the rolling elements 26 each have a horizontally extending axis of rotation in the mounting position. With the side bar 30 of the middle rail 11, a transverse web 31 is connected, which protrudes from the side web 30, preferably substantially at right angles. The side bar 30 of the middle rail 11 is provided with at least one extending in the longitudinal direction of the center rail 11 stiffening groove 32, which is located approximately halfway up the side bar 30.
