    The present invention relates to a drawer pull-out guide, comprising: - a cabinet rail to be fastened to a furniture body, - a drawer rail to be fastened to a drawer, which is movably mounted relative to the cabinet rail, - a middle rail, which is movably mounted between the cabinet rail and the drawer rail is, - a bearing with at least one support roller over which the drawer rail is supported in the closed state on the carcass rail.
    Furthermore, the invention relates to an arrangement with a drawer and with a drawer extension of the type to be described.
    In the AT 4518 U1 and in EP 1 470 770 A1 each Schubladenauszieh-guides are described, wherein in the front region of the carcass rail a bearing is arranged with at least one support roller This support roller is provided that the pull-out or the drawer connected to the closed state is supported. The support roller lies against a lateral edge region or at a bend of the pull-out rail. By the support roller, the rolling elements of carriages, which are movably mounted between the rails for transmitting the load of the drawer, relieved of the weight of the drawer and thus protected from deformation. Furthermore, the support roller causes the drawer is slightly raised in the closed state and an undesirable lowering of the drawer is prevented. Thus, the horizontally extending joints between the front panels of superimposed drawers of a cabinet can have a constant width, so that the visible from the outside joint image is also visually appealing.
    Object of the present invention is to provide a drawer extension of the type mentioned with a more compact design.
    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 provided that the bearing is arranged at a front end region of the center rail or the drawer rail and is arranged immovably in the longitudinal direction of the rail on which the bearing is arranged, during operation.
    In other words, the support roller is arranged more centrally in the rail system of the Schubtadenausziehführung compared to the cited prior art, wherein the space between a side web of the drawer rail and the furniture body reduced and the drawer extension can be made narrower overall.
    By a central arrangement of the support roller in the guide system also gives a central load distribution, wherein the at least one support roller between adjacent and mutually movable rails of the drawer extension guide can be accommodated in a space-saving comparatively narrow intermediate area. Unlike the cited prior art, in which the support roller is mounted laterally, in the construction according to the invention also no lateral tilting moment is exerted on the carriage located between the rails, so that the carriages are largely loaded vertically and no distortion of the drawer extension guide is brought about. Moreover, it is no longer absolutely necessary to provide the drawer rail with a bend, through which the drawer rail can be supported on the support roller, because in the embodiment according to the invention the support roller can interact directly with the catwalks of the rails.
    According to one embodiment, provision can be made for the carcass rail to be mounted on the furniture body via a fastening section, the drawer rail having a side web facing the fastening section, With the side rail of the drawer rail between the support roller and the footrest, it is possible to move the side rail of the drawer rail Attachment portion of the carcass rail is arranged.
    In a further embodiment it can be provided that the middle rail has a side profile section facing the side web of the drawer rail, wherein the lateral profile section of the middle rail is arranged between the support roller and the side web of the drawer rail.
    The drawer rail may have a cavity bounded by the rail profile of the drawer rail, the support roller being disposed within this cavity. In this case, it may be favorable if the drawer rail has two side webs and a middle web connecting the side webs, preferably flat, wherein the support roller is arranged completely within the two side webs of the drawer rail. The support roller can cooperate on the one hand with the underside of the central web of the drawer rail, on the other hand with a catwalk of the carcass rail.
    The bearing with the support roller may for example be arranged on the drawer rail, wherein the support roller cooperates in the closed state of the drawer rail with the cabinet rail.
    In a full extension is usually provided that the drawer extension has a displaceably mounted between the carcass rail and the pull-down middle rail. Here, the bearing may be mounted with the support roller on the center rail, wherein the support roller cooperates on the one hand with the carcass rail, on the other hand with the drawer rail.
    The support roller is arranged at a front end region of the middle rail or at a front end region of the drawer rail, wherein the support roller rotatably but in the longitudinal direction of the rail on which the bearing is arranged, in operation (ie with a relative movement of the rails 5,7, 8 mutually) immovably arranged. The "front end region of the rail" is to be understood in each case the foremost third of the length of the middle rail or the foremost third of the drawer rail in the mounted position.
    The arrangement of the bearing with the support roller on the center rail or on the drawer rail jamming of carriage or rolling elements - which are usually slidably mounted between the rails of Schubladenausziehführung - are largely avoided, whereby the running of the drawer extension guide is improved.
