Description

The present invention relates to a fixable on a side wall of a furniture body guide rail furniture pull-out guide, with at least one mounting flange for fixing the guide rail on a side wall and a distance to the mounting flange guide web for longitudinal guidance of another rail part of a furniture drawer slide, wherein the distance between the mounting flange and the guide web is changeable.

Guide rails of the generic type are known per se.

In furniture, the outer width of a furniture body is standardized and considered as a fixed measure. The inner width or the clear width of the furniture body, however, can vary greatly, due to the fact that different strong materials are used for the side walls.

For example, it is known to use side walls with a thickness of 19 mm, but it is also possible to use side walls with a smaller wall thickness.

As a result, the inside width of a furniture body tends to be smaller when using relatively thick side walls than when using side walls of smaller thickness or wall thickness.

The most used wall thickness of the side walls in furniture is 19 mm. On such a wall thickness of the side walls then of course also pull-pull parts are designed as drawers, that is, such furniture drawer parts can be easily mounted in a furniture carcass via corresponding pullout guides with guide rails, in which the guide bar has a fixed and non-variable distance to the respective mounting flange.

If now such a furniture pullout is used, for example in the form of a drawer in a furniture body whose side walls have a thickness of less than 19 mm, it is necessary to use furniture pullout guides whose guide rails deviating from the "standard version" a greater distance between the guide bar and mounting flange exhibit. Since sidewalls are used in furniture making, which have different deviations from the standard version of 19 mm, a correspondingly large number of drawer guides must be provided, in which the respective distance between the guide bar and mounting flange in the guide rails on the different wall thicknesses of the sidewalls used are coordinated.

This means a large storage and a large manufacturing effort, added that between the manufacturer of the drawer guides on the one hand and the furniture manufacturer on the other hand must always be clarified in advance, which wall thickness is actually used.

On the other hand, the problem of different wall thicknesses and the concomitant different inner widths of a furniture body with respect to the assembly of furniture parts such as drawers or the like can also be solved by the fact that uniformly dimensioned pullout guides are used in all cases, but on the other hand the furniture pullout parts in their width must be adjusted accordingly. This means that the furniture drawer parts must have different width dimensions, so that a drawer manufacturer needs to hold different widths designed drawers for different wall thicknesses.

For the reasons mentioned above furniture pull-out guides have been developed in which the distance of the guide webs is variable to the respective mounting flanges to bring in this way the guide webs always in a plane in which they can cooperate with other rail parts of a pullout guide , This ultimately has the advantage that a standardized width dimension for a furniture drawer part as a drawer can be maintained, regardless of how large the effective internal width of a furniture body is.

The known furniture pullout guides with variable in their distance from the mounting flange guide webs of the guide rails are quite complex and therefore also relatively expensive.

The present invention has for its object to provide a guide rail of the generic type, which allows the advantage of variable distance between the guide bar on the one hand and the mounting flange on the other hand despite simple and inexpensive constructions.

This object is achieved by features of claim 1. A guide rail according to the preamble of claim 1 is made EP 0 927 530 A1 known.

The invention is insofar the idea based on the at least one mounting flange to arrange at least one support member, with which the guide web is connected and which is displaceable relative to the mounting flange displaced together with the guide web and extent in its distance from the mounting flange.

Such a construction is relatively easy and inexpensive to implement and offers all possibilities to be able to compensate for different interior widths of a furniture body during the assembly of a furniture extracting part via a corresponding furniture drawer guide.

According to a preferred embodiment, it is provided that the holders are each displaceable relative to the mounting flanges steplessly against the action of a spring.

In this case, a displacement of the drawer in the effective direction of the springs only without loading the drawer is possible, the loading of a drawer then ultimately leads to the determination of the drawer slide on the mounting flanges.

Alternatively, each mounting flange may be laterally provided with locking devices which determine the drawer slide in the effective direction of the springs after the first insertion of a drawer. Changing the position is then possible only with great effort or by using tools. A determination of the pullout guide on its operating position is useful so that the springs do not permanently exert lateral forces on the pullout guide and thus lead to increased wear of the pullout guide.

Advantageous embodiments of the invention are the subject of dependent claims and will become apparent from the following description of exemplary embodiments illustrated in the drawings.

In the FIGS. 1 to 9 is denoted by the reference numeral 1, a guide rail of a furniture drawer guide not shown, wherein the guide rail 1 can be fixed in a known manner on a side wall of a furniture body. For this purpose, the guide rail 1 in the embodiment of the FIGS. 1 to 7 equipped with an approximately the length of the guide rail 1 corresponding mounting flange 2, which is provided with through holes 3 for mounting screws, by means of which the guide rail 1 is festschraubbar to a side wall of a furniture body.

In the embodiment of the FIGS. 8 and 9 In contrast, two mounting flanges 2 are provided, which are located at the rear and in the front end region of the guide rail 1. These mounting flanges 2 are provided with through holes 3 for mounting screws.

Of course, the mounting flange 2 or the two mounting flanges 2 can be set in any other suitable mounting on a side wall of a furniture body.

Of course, the guide rail 1 but also be fixed in any other suitable form on a side wall of a furniture body.

The guide rail 1 further has a guide web 4, which is intended for longitudinal guidance of another rail part of a furniture drawer slide. In the simplest case, the further rail part may in this case be the running rail of a furniture drawer guide, which in turn is coupled to a furniture drawer part. But it may also be a so-called center rail, along which in turn the running rail is displaced, resulting in an extension extension.

In the first case, one speaks of a partial extract, in the second case of a full extension, which states that in a furniture drawer slide with guide rail and track the furniture drawer, such as a drawer, can not be completely pulled out of a furniture body, resulting in a so-called full extension with a Extending middle rail is the case.

However, these considerations are not causally related to the present invention and have been mentioned only for a better understanding of the function and task of the guide rail 1.

As the FIGS. 1 to 7 show the guide bar 4 of the guide rail 1 is supported by two brackets 5, which are pushed onto a relative to the mounting flange 2 angled and integrally formed with the mounting flange 2 boom 6 and relative to the mounting flange 2 are displaceable.

As the FIGS. 8 and 9 combined with FIG. 10 show the guide bar 4 is supported by two brackets 5, which are pushed onto the two arms 6 of the two mounting flanges 2 and relative to the mounting flanges 2 are displaced.

It shows the FIG. 10 a mounting flange 2 in addition to boom 6 according to the embodiment of the FIGS. 8 and 9 ,

As in particular the blasting image representation in FIG. 7 shows the boom 6 is provided in the front and in the rear end with notches 7 and 8, through which two tongues 9 and 10 are formed. These tongues 9 and 10 allow the attachment of the apertures 11 and 12 provided with brackets 5 on the boom 6, wherein the tongues 9 and 10 engage in the openings 11 and 12 of the respective brackets 5.

Between the two tongues 9 and 10, a spring 13 is arranged in the region of the local incision 7, which is supported on the one hand at the bottom of the recess 7 and on the other hand on a web 14 between the two openings 11 and 12. This spring can be designed as a compression spring.

At the tongues 9 and 10 are outside and adjacent to the mounting flange 2 undercuts 15 and 16 are provided. These undercuts 15 and 16 are engaged behind by the respective outer boundaries of the openings 11 and 12, so that the holders 5 after being pushed onto the tongues 9 and 10 can only be removed from the boom 6 with an increased effort.

The brackets 5 are transversely displaceable transversely to the mounting flange 2, so that the distance of the brackets 5 to the mounting flange 2 is continuously variable. The brackets 5 are constantly loaded by the springs 13.

The brackets 5 are provided with parallel to the mounting flange 2 extending slots 17, in which the guide web 4 engages to achieve a clamping action. Together with the brackets 5 thus also the distance of the guide bar 4 can be changed relative to the mounting flange 2.

In FIG. 2 is a position of the brackets 5 and thus also of the guide bar 4 shown, in which the brackets 5 and thus also the guide bar 4 occupy a middle distance to the mounting flange 2. In FIG. 4 is shown that the brackets 5 and thus also the guide bar 4 occupy their maximum distance from the mounting flange 2. FIG. 6 Finally, shows a position of the brackets 5 and thus also the guide bar 4, which corresponds to the smallest possible distance between the guide bar 4 and the mounting flange 2.

The Figures 2 . 4 and 6 make it clear so far that a relatively large adjustment of the distance between the mounting flange 2 and the guide bar 4 is made. This creates the opportunity to use a furniture drawer guide, which is equipped with a guide rail 1 according to the invention, in cabinet furniture with different sizes interior widths, without having to change the width of a furniture drawer part such as a drawer. It can find furniture drawer parts such as drawers use whose dimensioning is designed for cabinet parts with the lowest usual internal width, which results when sidewalls are used with wall thicknesses of 19 mm. In such an application, the guide bar 4 is then displaced maximally in the direction of the mounting flange 2. If sidewalls are used whose wall thickness is less than 19 mm, the result is a greater inner width of the furniture body. Even then, a use of a furniture drawer slide with a guide rail 1 according to the invention possible because a compensation of this larger inner width by displacement of the guide web 4 in the sense of increasing the distance between the guide web 4 and mounting flange 2 is possible.

It is conceivable to use corresponding drawer guides both on the left and on the right side of a furniture drawer part, but it is also conceivable, on one side of the furniture drawer part, a non-adjustable drawer slide and only on the opposite side an adjustable drawer slide with a guide rail 1 - as described above. In this case, although the drawer would be arranged somewhat asymmetrically within the body, but this can be compensated visually by appropriate settings of a front panel, which closes the drawer to the outside.

In the FIGS. 11 to 13 an embodiment of the invention is shown in which the guide rail 1 consists of two separate components, that is, that only portions of a one-piece or continuous guide rail 1 are provided. As the FIGS. 11 and 12 show, the guide-relevant part of two non-interconnected guide webs 4, which in turn are arranged on brackets 5 and supported by these. The two brackets 5 are pushed onto boom 6 of mounting flanges 2 and can be changed in their distance from the mounting flanges 2, as in the embodiment of the FIGS. 1 to 9 ,

The guide webs 4 can be designed in any manner so that they can run a running rail 18 which is connectable to a drawer, in the longitudinal direction of the track rail 18 properly.

Thus, the guide webs 4 may for example be provided in their encompassed by the running rail 18 area with rollers or sliders that are adapted to the cross-sectional shape of the track rail 18.

How the particular Figures 12 and 13 make it clear, the distance to the mounting flanges 2 can be changed by the displacement of the brackets 5 and thus also the guide webs 4, so that even in this embodiment of the invention, the possibility exists, a drawer or any other furniture drawer part in cabinets with different internal width use.

The running rail 18 is provided in its rear end with an end cap 19 to which a fishing hook 19a is formed, which serves the rear coupling of the running rail 18 with a drawer. In the front end region, a closure plug 20 is placed on the running rail 18, which is equipped with pins 20 a. These pins 20a serve to couple a drawer or any other furniture drawer part in the front end region with the running rail 18. The sealing plug 20 may be arranged adjustable in height relative to the retaining rail 18 in order to allow an adjustment of a furniture extracting part in a horizontal position.

The FIGS. 14 to 17 show an embodiment of the invention, which is comparable to the embodiment of the FIGS. 8 to 10 However, this differs from this embodiment in that the holders 5 have only one opening 11, which allows the sliding of the holders 5 on the boom 6 of the respective mounting flanges 2.

In this case, a resilient support of the brackets 5 is not possible. Rather, in the embodiment according to the FIGS. 14 to 17 For example, each holder 5 is provided on the underside with latching recesses 21, which are arranged offset relative to the mounting flanges 2 in the direction of displacement of the holders 5 and in the latching projections 22, which may be formed by features on the arms 6, engage. Thus, a stepwise adjustment and securing of the brackets 5 in its displacement position relative to the mounting flanges 2 is possible here. This is in many cases quite sufficient, since different wall thicknesses for the side walls of a cabinet also have step-like differences in the millimeter range.

The Figures 14 and 16 clearly show that the supported by the brackets 5 guide webs 4 are provided for guiding a running rail with rollers 23, wherein two rollers 23 are arranged side by side. These rollers 23 serve to support and low-friction guidance of a running rail, for example, the shape of the in the embodiments of the FIGS. 11 to 13 shown running rail 18 may have.

In the FIG. 18 Guide rail 1 shown in a perspective exploded view again consists of two separate sections as in the embodiments according to the FIGS. 11 to 17 , Again, mounting flanges 2 are provided with arms 6, which are provided in this embodiment, however, with a slot 7, within each of which a spring 13 is arranged. Through the respective slot 7 two tongues 9 and 10 are formed, which can engage in openings 11 and 12 of the brackets 5. At their outer end edges, the tongues 9 and 10 are equipped with undercuts 15, which allow the locking of the brackets 5 to the arms 6.

The respective spring 13 is supported once at the bottom of the slot 7 and on the other hand on a web 14 separating the apertures 11 and 12 from each other. This results in a stepless adjustability of the brackets 5 and thus also the guide webs 4 relative to the respective mounting flange 2 analogous to the construction of the FIGS. 1 to 9 ,

The guide webs 4 carry rollers 23 for supporting and low-friction guidance of a running rail.

The peculiarity of the guide rail 1 according to FIG. 18 consists in that on one of the guide webs 4, a spacer rod 24 is arranged, which can engage in a sleeve 25 of the opposite portion of the guide web 4. Thereby, the distance between the two brackets 5 is fixed to each other, the same course also applies to the two mounting flanges 2 with their arms 6, as soon as they are inserted into the openings 11 and 12 of the two brackets 5. Thus, an assembly unit results in a fixed predetermined distance of the mounting flanges 2 to each other on the inside of a side wall of a furniture body can be attached.

It has been shown and described that the holders 5 can be infinitely adjustable relative to the mounting flanges 2 and are loaded by springs 13. It has also been shown and described that a stage adjustability of the brackets 5 relative to the mounting flanges 2 can be realized.

The FIGS. 19 and 20 show a front view and a section through the mounting flange 2 in the position of the holder 5 with the smallest width of the furniture body. The holder 5 is in this position on the body-side stop 27.

The FIGS. 21 and 22 show a front view and a section through the mounting flange in the position of the holder 5 at the greatest width of a furniture body furniture. In this position, the holder 5 is located on the inside-side stop 28.

Beyond the embodiments shown, it is of course also conceivable, in the area of mutually interacting surfaces of the brackets 5 and the boom 6 sawtooth-like notches 28 according to FIG. 23 provide that allow under a certain force corresponding to the pitch of the sawtooth-like detents a fine-scale adjustment of the brackets 5 relative to the mounting flanges 2. Furthermore, the notches 29 allow the absorption of the spring forces in the direction of the pullout guide 1 after positioning the pullout guide 1 by the drawer 25. Thus, after the latching no lateral force is exerted more on the pullout guide 1, which could lead to an increase in wear.

If guide rails 1 are used in which the brackets 5 are loaded under the action of springs 13, take the brackets 5 and thus the guide webs 4 and guided on the guide rails 4 running rail 18 before the coupling with a furniture drawer part such as a drawer always the largest distance to the mounting flanges 2 a.

If now after the attachment of such guide rails 1 on the side walls of a furniture body, a drawer are coupled to the rails 18, it may be necessary to move the rails 18 in the direction of the mounting flanges 2. For this purpose, it may be helpful if a drawer 25, as in FIG. 25 shown, in its rear, near-bottom end region with respect to the direction of displacement of the rails 18 angled bevels 26 is provided which can be inserted at the smallest possible distance between two rails 18 on the left and on the right side of a furniture body between these two rails 18 to then at the final attachment of the drawer on the rails 18 to spread them apart, so to speak, and adapt to the width of the drawer 25. This results in a great ease of assembly, since it is not necessary to move the rails 18 by hand so far that a correspondingly sized drawer can be applied.

The invention is not limited to the exemplary embodiments illustrated in the drawings, since, as already mentioned in the text of the description, various modifications of a constructive nature are possible, but are obvious to a person skilled in the art through the illustrated exemplary embodiments and the description.
