Description:
[0001]    This application is a National Phase Application of PCT/EP2009/053450, filed on Mar. 24, 2009, which is based upon and claims the benefit of priority to German Patent Application No. 20 2008 004 100.7, filed on Mar. 25, 2008, the contents of both of which Applications are incorporated herein by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    The present disclosure relates to a telescoping pullout for a pullout guide which is extensible and retractable in a furniture body. The pullout guide has a fixed guide rail, which is fixed by at least one fastener on the furniture body. 
         [0003]    A telescoping pullout guide is known in many embodiments. In a simple embodiment, it still contains a pullout guide fixed on the pullout, which is guided by the fixed guide rail during extension and retraction of the pullout. However, in order that the pullout can be pulled nearly completely out of the furniture body, pullout guides having a so-called middle rail, which is also movable in relation to the guide rail and is guided thereby, are also known. 
         [0004]    The furniture body can be a cabinet, but can also be the housing of a household appliance, such as a dishwasher, a refrigerator, or the like. Depending on the type of the furniture body, the pullout is designed as a drawer, a basket, or a similar tray, for example. 
         [0005]    In the pullout guide, the guide rail and the pullout rail, and optionally also the middle rail, comprise steel. In the pullout guides known up to this point, the connections between the fasteners and the guide rail are formed by welded-on angles. This solution, which is known, is subject to the disadvantage, however, that surface-coated components may not be used, for example, if they are lacquered, powder coated, or provided with a zinc coating. 
         [0006]    The present disclosure relates to a telescoping pullout guide designed in such a manner that welded-on connectors can be dispensed with, so that profiles or rails which are already provided with a surface coating may also be used. 
         [0007]    The pullout guide, according to the present disclosure, includes a connection between the guide rail and each fastener that is formed from at least one angled web, which engages in a perforation and overlaps the adjoining edge area, and a securing web inserted into an opening. 
         [0008]    A pocket is formed by each angled web, into which the area adjoining the perforation is inserted. In order that the guide rail is secured against a displacement in the pullout direction of the pullout, the securing web is also shaped or pressed into an opening. A further advantage occurs in that the surface coatings of the rails of the pullout guide and the fasteners may be different. 
         [0009]    In a first embodiment, it is provided that each angled web is formed by shaping of a notch provided in the guide rail. Using a suitable tool, this notch and the shaping can be produced in one work step. A further advantage occurs in that no waste arises. Because the guide rail comprises steel, cold shaping is possible. 
         [0010]    It is further provided that each angled web, in relation to the installed location of the pullout guide, is shaped from the lower leg of the guide rail. The lower leg of the guide rail can be in the plane of the floor or parallel and at a distance thereto in the case of a pullout in the form of a drawer. 
         [0011]    In a further embodiment it is also provided that the free leg of each angled web overlaps the area of the guide rail adjoining the perforation. 
         [0012]    Furthermore, it is provided that each fastener is connected to the guide rail by at least two spaced-apart angled webs. The guide rail is typically connected via two spaced-apart fasteners, so that the connection is produced as a whole by four angled webs. 
         [0013]    For easier insertion of the fasteners into the pocket delimited by the angled webs, it is provided that the end area of each free leg of the angled web is angled to form an insertion bevel. 
         [0014]    To secure the guide rail against the pullout direction of the pullout, it is also provided that the securing web is transverse to the central longitudinal axis of the guide rail. In an embodiment, the securing web engages in an opening. The securing web engages in an opening which is provided in the guide rail. Each securing web is formed, according to this embodiment, by deformation of a web remaining between two punched-out areas in the leg of the fastener. 
         [0015]    In a another embodiment, the fasteners may be implemented as fastening angles. The leg associated with the guide rail is connected thereto in the way already described, so that the other leg presses against the facing surface of the furniture body. The connection to the furniture body can be performed by screws, for example. If the furniture body comprises metal, suitable connectors may also be used, such as rivets and the like. These fastening angles may be connected to the guide rail in such a manner that the contact leg is laterally adjacent to the rail system or is oriented downward. 
         [0016]    In a further embodiment, it is also provided that the above-described connection between the guide rail and each fastener can also be used in order to receive a pullout part movable out of the furniture body, for example, if the furniture body is part of a refrigerator. The body of the refrigerator is to remain unchanged. It is therefore provided in a further embodiment that the fastener for the telescoping pullout guide is implemented as a holding plate, whose edge areas are fixed on diametrically opposing walls of the furniture body. 
         [0017]    In this embodiment, it is possible that the intermediate floor, which is provided for subdividing the refrigerated space, or the floor itself is used in a refrigerator to fix the pullout guide thereon, for example. 
         [0018]    In this embodiment, it is provided that the holding plate has the perforations, in which the angled webs of the guide rails engage, in the edge areas. In this embodiment, the legs of the fastening angles perpendicular to the side walls of the furniture body are replaced by the edge areas of the holding plate. 
         [0019]    To fix the edge areas of the holding plate, it is advantageously provided that the edge areas of the holding plate are each fixed on at least one holding web, which is fixed on the side walls of the furniture body. These connections may be designed so that the holding plate is fixed in a formfitting and/or friction-locked manner inside the furniture body. 
         [0020]    However, the side walls which delimit the refrigerated space of a refrigerator are typically provided on the sides facing toward one another with two spaced-apart holding webs, into which the edge areas of intermediate floors are insertable. It is therefore provided in a further embodiment that the edge areas of the holding plate are fixed in a formfitting and/or friction-locked manner in a slot formed by two spaced-apart holding webs. This can be achieved, for example, by a corresponding thickness of the holding plate. The connections between the edge areas of the holding plate and the two lower legs of the guide rail are identical or approximately identical to the connections using the angled fasteners. 
         [0021]    Other aspects of the present disclosure will become apparent from the following descriptions when considered in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION 
       [0032]    A pullout guide  10  is shown, for example, in  FIGS. 1-3 . Pullout guide  10  comprises a pullout rail  11 , which is extensible, a middle rail  22 , and a guide rail  12 , which is fixed on a furniture body (not shown) by two fasteners in the form of fastening angles  13 ,  14 . For example, a drawer (not shown) is fixed on the pullout rail  11 . For this purpose, the pullout rail  11  is equipped with a holding angle  15  and a front stop  25  in the pullout direction.  FIG. 1  also shows an end location damper  24 . A connection of the guide rail  12  to angled webs  16 ,  17  is explained in greater detail hereafter. 
         [0033]    The embodiment according to  FIGS. 2 and 3  shows pullout guide  10  having a pullout-extending middle rail  22 , which is extensible by a specific amount.  FIG. 2  shows that a lower leg of the guide rail  12  is provided with angled webs  16 ,  17 . These angled webs  16 ,  17  are formed by notches, the material areas delimited by the notches being shaped into the angled webs  16 ,  17 . An associated leg of the fasteners  13 ,  14  is provided with perforations  18 ,  19 , through which the angled webs  16 ,  17  may be guided. After displacement of the guide rail  12  in the pullout direction, these angled webs  16 ,  17  overlap adjoining edge areas and form an undercut against lifting off. This is recognizable in  FIG. 4 . Furthermore, as shown in  FIG. 4 , two punched-out areas  20 ,  21  are provided in an end area of each leg of the fastening angle  13 ,  14 , which are separated from one another by a securing web  26 . In the course of the manufacturing of the pullout guide  10 , this securing web  26  is deformed and engages in an opening (not shown) of the guide rail  12 . Securing in the longitudinal direction of the guide rail  12  is thus provided. 
         [0034]    As suggested, for example, in  FIGS. 1-4 , the fasteners in the form of the fastening angles  13 ,  14  are connected in a formfitting and friction-locked manner to the guide rail  12 . The pullout-extending middle rail  22  allows an over-extension. 
         [0035]      FIGS. 3-5  suggest that the angled webs  16 ,  17  penetrate the perforations  18 ,  19 , and the free end area of the free leg is bent over to form an insertion bevel. The free end areas of the angled webs  16 ,  17  engage below the edge areas formed by the perforations  18 ,  19 . 
         [0036]      FIGS. 6 through 8  show an embodiment in which two telescoping pullout guides  10  are fixed on edge areas of a holding plate  23  in the same way as on the fastening angles  13 ,  14 .  FIGS. 6-8  suggest, for example, that the angled webs  16 ,  17 , which are shaped out of the legs of the two guide rails  12  and facing toward one another, engage below the holding plate  23 . The pullout guides  10  correspond to those of  FIGS. 1 through 5 . 
         [0037]      FIG. 6  shows that the pullout guides  10  are at a distance to outer longitudinal edges of the holding plate  23 , so that the lateral edge areas may be fixed on holding webs of the furniture body (not shown).  FIG. 7  shows that each pullout guide  10  comprises the pullout rail  11 , the guide rail  12 , and a pullout-extending middle rail  22 .  FIG. 6  also shows that each pullout guide  10  is equipped with an end location damper  24 . 
         [0038]      FIG. 8  shows that the edge areas of the holding plate  23  are each provided with four perforations  18 ,  19  situated at a distance to one another, in which the angled webs  16 ,  17  are configured to engage in the way already described. Also shown are perforations  27 . 
         [0039]    The edge areas of the holding plate  23  are inserted into slots, which are attached or shaped onto the side walls of the furniture body delimiting the refrigerated space, for example, in a way not shown. A pullout part, for example, a drawer, can be fixed on the pullout guide  10  via the pullout rail  11  in a way not shown. 
         [0040]      FIG. 9  shows an embodiment, according to the present disclosure, in which the telescoping pullout guide  10  is fixed on the fasteners  28 ,  29  in the same way as on the fastening angles  13 ,  14 . 
         [0041]    The angled webs  16 ,  17 , which are shaped from the legs of the two guide rails  12  facing toward one another, engage below the fasteners  28 ,  29 . The pullout guide  10  corresponds to those of  FIGS. 1 through 5 . The fasteners  28 ,  29  are configured for the floor installation of a pullout guide  10  in a body of a refrigerator, for example. 
         [0042]      FIG. 10  shows an embodiment, according to the present disclosure, in which the telescoping pullout guide  10  is fixed on the fastening angles  30 ,  31  in the same way as on the fastening angles  13 ,  14 . 
         [0043]    The angled webs  16 ,  17 , which are shaped from the legs of the two guide rails  12  facing toward one another, engage below the fastening angles  30 ,  31 . The pullout guide  10  corresponds to those of  FIGS. 1 through 5 . The fastening angles  30 ,  31  are configured for side wall installation of a pullout guide  10  in a body of a refrigerator, for example. 
         [0044]    According to the present disclosure, it is important that angled webs  16 ,  17 , which are formed through deformation by notches in the legs of the guide rails  12 , are situated on the guide rails  12 . Each fastener  13 ,  14  is provided, for example, with two perforations  18 ,  19 , and may also be provided with perforations  27 . Furthermore, it is important that punched-out areas  20 ,  21  are provided in the fasteners  13 ,  14 , which are separated from one another by a securing web  26 , which is shaped into an opening of the guide rail  12  by deformation. The securing against the pullout direction of the pullout guide  10  is thus achieved. 
         [0045]    However, pullout guide  10  does not have to have pullout-extending middle rail  22  to implement the fastening solution according to the present disclosure. 
         [0046]    Although the present disclosure has been described and illustrated in detail, it is to be clearly understood that this is done by way of illustration and example only and is not to be taken by way of limitation. The scope of the present disclosure is to be limited only by the terms of the appended claims.
