    The invention relates to a pull-out guide for a drawer comprising a cabinet rail to be fastened to a furniture body, a drawer rail to be fastened to the drawer, and a middle rail movably mounted between the carcass rail and the drawer rail, at least one carriage having at least between the middle rail and the drawer rail a rolling element is movably mounted, and wherein the at least one rolling element runs on at least one support profile of the middle rail.
    Such pull-out guides are state of the art and are described, for example, in German Utility Model DE 20 2009 003 883 U1. In this case, the Mitteischiene is formed such that - viewed in cross section - on both sides has two support profiles on which the ball bearings run two carriages. The support profiles serve the purpose of preventing lifting of the carriage from the center rail and / or the Kippspiel usually occurring in Ausziehführungen without support profile, which comes about by the relative play between the rails or the at least one carriage, to reduce.
    This middle rail thus differs from the usually present form of a U-profile with two vertical webs and a horizontal rail which connects the two vertical webs together, the deviation is mainly in the folds between the two vertical webs and the horizontal rail.
    The disadvantage here is that the production of the center rail and thus the entire pull-out by this special shape, which requires a special bending process, compared to the standard form is very expensive and expensive.
    The object of the present invention is to avoid the disadvantages described above and to provide a comparison with the prior art simplified and less expensive pull-out.
    To solve this problem, the invention provides that the at least one support profile is arranged as a separate structural unit on the center rail.
    The invention is based in particular on the recognition that it is only necessary under certain circumstances that the center rail has a support profile for preventing the lifting of a carriage. Normally, the weight of the drawer is relatively evenly distributed on the pull-out guides, so that there is no risk of lifting. In these cases, the at least one support profile can easily be omitted and thus material can be saved. However, if the pull-out guide is to be used for drawers, e.g. have a very heavy front panel compared to the other drawer components and are therefore very top heavy, so the at least one support profile in particular is necessary to avoid tipping out the drawer front in the inserted state of the drawer.
    Due to the fact that the at least one support profile is a separate structural unit according to the invention, it is possible to retrofit the center rail modularly specifically for rather rare special cases, whereby this retrofitting can be done either at the factory during the production of the pull-out guide or on the user side ,
    It should also be noted that the at least one rolling body running on the at least one supporting profile may be a roller, roller or ball.
    In order to avoid the mentioned tipping out of the drawer front in the inserted state of the drawer, two measures may preferably be provided. One measure consists in that the at least one carriage engages under the at least one support profile in the use position of the pull-out guide with the at least one rolling element for securing against lifting off the middle rail. The other measure provides that at least one support web is arranged on the drawer rail and the drawer rail engages under at least one rolling element arranged on the at least one carriage in the use position of the pull-out guide with the at least one support web for securing against lifting of the at least one carriage. If both measures are realized, the lifting of the drawer, which is attached to the drawer rail, prevented by the pull-out - in short - by a double undercut.
    In an advantageous embodiment of the invention, the at least one support profile extends at least in sections in the longitudinal direction of the middle rail. To prevent the drawer front from tipping out in the inserted state of the drawer or to reduce the tilting play described in the introduction, it may moreover be sufficient if the at least one support profile only extends over a partial area of the middle rail in the longitudinal direction - expressed in numbers over a partial area of 20% to 60%, preferably over a portion of 30% to 40% of the middle rail - extends. If exactly two carriages are movably mounted between the middle rail and the drawer rail, then it can be provided that the at least one support profile extends in the longitudinal direction only via a rear portion of the middle rail or that partial region of the middle rail arranged in the vicinity of the drawer rear wall, in which the second, rear carriage is movably mounted.
    Further details and advantageous embodiments of the invention, which are defined in the dependent claims are explained in more detail in the context of the following description of the figures with reference to FIGS. Showing:

    Figures 1 a and 1 b show in a schematically illustrated perspective view of a drawer unit 25 with two superimposed drawers 2. The two drawers 2 are each attached via two right and left arranged pull-1 on the furniture body 3 of the drawer unit 25 and can on this Drawer guides 1 are pushed into the drawer unit 25 and pulled out. The two drawers 2 are very top-heavy drawers, as they have a low depth and their front end 26 on the other comparatively difficult to the other drawer components, comprising the drawer rear wall 12, the two drawer side walls 27 and the drawer bottom 28, are. The two pull-out guides for the upper drawer, in contrast to the pull-out guides the lower drawer to the support profiles 10 and 11 according to the invention, whereby a tilting out of the drawer front 26 is prevented in the upper drawer compared to the lower drawer in the retracted state of the drawer.
    The details of the two pull-out guides 1 of the upper drawer are explained in more detail below with reference to FIGS. 2 a, 2 b, 3 and 4. Concretely, with these pull-out guides 1 a so-called full extension can be realized, i. that the drawer rear wall in the extended state of the drawer in the
    Front level of the drawer unit is located. This is realized in that the pull-out guide 1 consists of three rails: a carcass rail 4, which can be fastened to the furniture body via holes 49 for receiving screws, a drawer rail 5 to be fastened to the drawer and one between the carcass rail 4 and the drawer rail 5 movably mounted center rail 6. The drawer rail 5 has in the illustrated preferred embodiment of the pull-out guide 1 three known peculiarities:
    First, a damped, spring-assisted collection device 29 is attached to the side of the drawer rail 5, which comprises a force accumulator in the form of a spring, said spring when pulling the pull-out 1 via a fixed to the rail 4 pin 31, located on the end face of an elbow 30th is biased. From a certain position when pushing the pull-out guide 1, this pin 31 again engages in a carriage attached to the spring, the stored energy in the spring is released and causes the complete retraction of the pull-out guide 1 over the remaining, still zurückzulegende route. For this movement to take place in a damped manner, the intake device 29 comprises a damping device counteracting the force-storing spring. A second feature of the drawer rail 5 is a height adjustment device 32 arranged in the front region, by means of which the front area of the drawer can be adjusted in height. The third feature is an adjusting device 33 for adjusting the position of the drawer relative to the drawer rail 5, wherein this adjusting device 33 is arranged in the rear region of the drawer rail 5. It comprises a retaining pin 34 which projects into a corresponding recess of the drawer rear wall. This adjustment device 33 also serves as insertion limit for the drawer.
    In the figure 2a and in Figures 3 and 4 it can be seen that the middle rail 6 in cross-section has substantially the shape of a U-profile, wherein the U-profile in the use position of the pull-out 1, two vertical webs 14 and 15 and a horizontal rail sixteenth , which connects the two vertical webs 14 and 15 with each other, and that on each of the two vertical webs 14 and 15 each have a support profile 10 and 11 is arranged as a separate unit. It should be noted that the bends between the two vertical webs 14 and 15 and the horizontal rail 16 form an angle α or ß of 90 °. The two support profiles 10 and 11 have in cross-section substantially an L-shape, wherein a first leg 17 or 18 of this L-shape in each case bears against the two vertical webs 14 and 15 and the second leg 19 and 20 of the L-shape is aligned perpendicular to the vertical webs 14 and 15. Further features of the supporting profiles 10 and 11 are that they are arranged above a horizontal center plane M of the middle rail 6 which is intended in the position of use of the pull-out guide 1, extend over a rear partial area T of approximately 35% in the longitudinal direction L of the middle rail 6, completely made of metal, • are welded to the center rail 6, and • are integrally formed.
    Between the middle rail 6 and the drawer rail 5, two carriages 7 and 35 are movably mounted, wherein the support profiles 10 and 11 extend only over the portion T of the center rail 6, in which the rear carriage 7 is movably mounted. This rear carriage 7 has two laterally in the carriage cage 39 rotatably mounted support rollers 8 and 9, which run on the two support profiles 10 and 11 of the middle rail 6. More specifically, in the position of use of the pull-out guide 1, they engage under the support profiles 10 and 11, respectively, in order to prevent lift-off from the center rail 6, i. that they run on the downwardly facing side 21 and 22 of the second leg 19 and 20 of the L-shape of the support profiles 10 and 11, respectively. It should be noted that the movement of these two support rollers 8 and 9 in the longitudinal direction L of the center rail 6 is limited on the one hand by a arranged on the support profiles 10 and 11 stop 13 and the other by a arranged on the center rail 6 stop 50. In the carriage cage 39 of the carriage 7 in addition to the two support rollers 8 and 9 even more rolling elements 36, 37 and 38 are rotatably mounted, via which the carriage 7 on the two vertical webs 14 and 15 and the horizontal rail 16 of the center rail 6 and at the Bottom of the drawer rail 5 expires. The front carriage 35 is basically the same as the rear one
    Carriage 7, with the difference that it has no support rollers for securing against lifting from the center rail 6. Between the middle rail 6 and the carcass rail 4, two carriages 46 and 48 are also movably mounted, said carriages 46 and 48 are coupled together via a coupling device 47. For the sake of completeness, reference should be made to a special feature of the preferred embodiment of the pull-out guide 1 according to the invention, which is known per se in the prior art. This is a synchronization device known per se from the prior art, which has a toothed rack 44 attached to the drawer rail 5 on the middle rail 6 fixed gear 45 and arranged on the movable between the middle rail 6 and the carcass rail 4 carriages 46 and 48 arranged rack and a synchronization of the movement of the drawer rail 5 relative to the center rail 6 and the movement of the center rail 6 relative to the between the middle rail 6 and the carcass rail 4 arranged carriage 46 and 48 causes.
    If one looks in more detail at the cross-sectional illustration of the preferred embodiment of the pull-out guide 1 according to the invention, as shown in FIG. 4, it can easily be seen that a flat, bent support web 23 or 24 is respectively arranged on the right and left of the drawer rail 5, these two support webs 23 and 24 are oriented parallel to the imaginary horizontal center plane M of the center rail 6. The drawer rail 5 engages with these two support webs 23 and 24, the support rollers 8 and 9 of the rear carriage 7 and thus prevent lifting the drawer rail 5 of the carriage 7, said carriage 7 in turn by means of the two support rollers 8 and 9 by the under reaching the support profiles 10 and 11 is secured against lifting from the center rail 6. Furthermore, it can be seen that the two lateral support rollers 8 and 9 of the rear carriage 7 have a different diameter D1 and D2, are arranged rotatably mounted at different heights on the carriage 7 and further the two support profiles 10 and 11 asymmetrically on the two vertical webs fourteenth and 15 of the center rail 6 are arranged.
    Although the invention has been described concretely with reference to the illustrated embodiment, it goes without saying that the subject of the application is not limited to this embodiment. Rather, measures and modifications that serve to implement the idea of the invention, of course, conceivable and desirable. For example, the support profiles in cross-section rather than the L-shape could have another, e.g. have an at least partially circular and / or elliptical shape or the contours of a right triangle underlying shape. It is also conceivable that the support profiles not (only) made of metal, but instead (or even) made of plastic or other materials. In addition, in addition to the abovementioned possibility of welding, there are many other possibilities for fastening the support profiles to the center rail, such as, for example, by riveting, screwing or soldering.
