Description

The present invention relates to a drawer slide with a fixable guide rail and a movable running rail, which is movably mounted along the guide rail or at least one optionally arranged between the guide rail and track rail middle rail, wherein a positioning means is provided to align the running rail in a closed position relative to the guide rail ,

The DE 20 2007 007 773 U1 discloses a combination of drawer and slide, in which the drawer can be latched to a rail of a pullout guide. In addition, a height adjustment is provided, in which an adjusting screw is held in a threaded sleeve which is fixed to a housing within a rail. By turning the adjusting screw, the drawer can be raised or lowered in the vertical direction. The combination of drawer and slide requires many components and is therefore expensive to manufacture. In addition, it is not possible to move a drawer, which was aligned exactly in a horizontal direction perpendicular to the longitudinal direction of the pullout guide, permanently in the closed position so that the actual joint pattern corresponds exactly to the set joint pattern. Due to the existing clearance between the rails or the fasteners and the rails, the joint pattern on a piece of furniture can appear irregular. Under joint image is understood in this context, the horizontal distance between the front panel of a thrust element and both side walls of a carcass. In this case, the body may for example be a piece of furniture or a dashboard of a motor vehicle.

In the DE 10 2007 005 555 A1 a storage container for an interior of a motor vehicle is described, which is arranged displaceably by means of guide rails on the instrument panel. In the interior of a motor vehicle, an optimal joint pattern and an optimal distance or an optimal alignment of two adjacent front panels are very important to each other. The guide rails have no means for achieving the optimum joint pattern. There are also guide devices for storage compartments are known which have gear transmission and thus are very expensive to manufacture.

The WO 2004/103119 A1 discloses a drawer with hollow side walls, on each of which a pullout guide is arranged. On a running rail of a pullout guide is an adjustment mechanism for a lateral Provision setting provided having a pivotable lever which is pivotable between a release position and a clamping position to fix a clip on the running rail.

DE 20 2008 013 096 U1 discloses a rail for a pullout guide in which a plug is inserted at the end for coupling with a self-closing mechanism and as a stop.

It is therefore an object of the present invention to provide a pullout guide that allows a particularly accurate and easy maintenance of the set joint image.

This object is achieved with a pullout guide with the features of claim 1.

According to the invention, the pull-out guide comprises a positioning means for aligning the running rail in a closed position relative to the guide rail, wherein the positioning means has at least one inlet bevel acting in a horizontal direction and perpendicular to the longitudinal direction of the pull-out guide - straight or curved - or at least one positioning aid. As a result, the positioning of the track rail in the horizontal direction can be done exactly what the exact setting of a joint gap between a front panel and the side walls of a carcass or between two juxtaposed front panels allows. In addition, the positioning of the running rail can be easily realized with only a few components by the mechanical guidance of the running rail.

In a preferred embodiment, the positioning means on two opposite inlet slopes, which taper towards the closing direction. As a result, the running rail can be caught and aligned both by the one and the other inlet slope, when the pullout guide moves in the closing direction. The angle of the inlet slopes to the longitudinal axis of the guide rail may be in a range between 1 ° and 25 °, in particular 5 ° to 20 °.

The positioning aid preferably has at least one roller, ball or at least one rounded bolt or at least one elastic element, etc., in order to align the running rail when retracting into the closed position. The use of rollers or balls is very advantageous because it results in lower frictional forces.

For a simple mounting of the positioning means, these are formed on a stopper, which can be fixed to the front side of the running rail or the guide rail. Such a plug can for example be made of plastic. A corresponding plug is known and serves primarily to cover sharp edges on the pullout guide.

According to the invention, the stopper is fixed to the running rail and preferably has a receptacle for inserting a wall of the guide rail, wherein the inlet bevels are formed on the receptacle. The plug may further comprise a first receptacle with the positioning means and a second receptacle which is horizontally oriented wider than the first receptacle in the region of a taper. The provision of two receptacles allows the plug to be mounted on a pull-out guide on both a right and a left side of a push element. On one side, the guide rail is then aligned with the positioning means, while on the opposite side, the guide rail is held on the second receptacle with play, so that alignment takes place only on one side and a "loose bearing" is provided on an opposite side.

Further, it is advantageous if means for height and or lateral adjustment of a thrust element are provided on the plug. Then, the plug can cause not only an orientation in the horizontal direction but also in the vertical direction. For this purpose, the plug may have an integrally formed thread into which a threaded bolt is inserted for height adjustment. To produce an integrally formed thread, two half shells of the plug can be assembled during assembly, so that only a few components are required.

A set of two pull-out guides and one push element is also provided, wherein a positioning means with at least one inlet bevel acting in the horizontal direction is provided on a first pull-out guide, while the opposite second pull-out guide has a play guide in the horizontal direction, so that the positioning means on the first Pull-out guide sets the horizontal position of the push element laterally to the longitudinal direction of the pullout guide in the closed position.

In this case, identical plugs are mounted on the first and the second pullout guide, each having a positioning means, wherein only at one stopper the positioning means in engagement with a rail of the pullout guide passes, while on the opposite side of the pullout guide is arranged with a play guide on the plug.

A piece of furniture 1 comprises a furniture body with a side wall 2, on which a pull-out guide 4 is fixed. About a right and a left pullout guide 4, a thrust element in the form of a drawer 3 is movably held. The pullout guide 4 in this case comprises a fixed to the side wall 2 guide rail 5, a middle rail 6 and a running rail 7, wherein the middle rail 6 can also be omitted in a partial extract.

In FIG. 1 is an abstract position and in FIG. 2 a retraction position of the pullout guide 4 is shown. On the running rail 7 of the pullout guide 4, a plug 10 is inserted frontally on which the drawer 3 is at least partially supported. The drawer 3 has, for example, a front panel holder 8, which can be aligned via means for height adjustment with an adjusting wheel 18 in the vertical direction. These means are preferably arranged in or on the stopper 10.

On the plug 10 positioning means 11 are further provided which can align the drawer 3 in a closed position in a horizontal direction laterally to the longitudinal direction of the pullout guide 4. As in FIG. 3 is shown, the plug 10 for this purpose a receptacle with positioning means 11 in the form of inlet slopes 12 and 13, which are formed on opposite sides of the receptacle. In the recording, a wall 50 of the guide rail 5 is inserted in a closing operation, wherein the receptacle has a depth between 5 mm and 50 mm, in particular 8 mm to 25 mm, so that the inlet slopes 12 and 13 over a short distance before reaching the Closed position are effective. Does the running rail 7 with a too small or too large distance relative to the side wall 2 on the guide rail 5, the inlet slopes 12 and 13 ensure that the running rail 7 is aligned relative to the guide rail 5 shortly before reaching the closed position, so that at least in the closed position, the lateral joint image, which has been set once exactly on the furniture is permanently maintained.

In the FIGS. 4A to 4D the plug 10 is shown in detail. The plug 10 is made of plastic, and comprises a first receptacle with the positioning means 11 for receiving the wall 50 of the guide rail 5. Adjacent to the first receptacle, a second receptacle 15 is formed, which is wider than the first receptacle, and in the likewise a wall 50 of a guide rail 5 can be inserted. When using two pullout guides 4 is then a guide rail 5 with a wall 50 on the positioning means 11 aligned, while on the opposite side, a wall 50 of the guide rail 5 is held in the second receptacle 15 with play. The inlet slopes 12 and 13 taper counter to the closing direction X and have at a taper 14 the smallest distance from each other, wherein the taper 14 has a width substantially equal to the width of the wall 50 of the guide rail 5.

The plug 10 also has a front plate 16, which specifies the insertion depth of the plug 10. From the front plate 16, projections 17 extend into a cavity of the running rail 7. It is also possible to provide locking and clamping means for stable attachment to the running rail 7 on the projections.

Further, a threaded opening is formed on the plug 10, into which engages a threaded bolt of a Verstellrades 18. By turning the adjusting wheel 18, the threaded bolt can thus be adjusted to raise or lower the drawer 3 in the region of the plug 10 and so make a vertical alignment can.

In FIG. 5 a modified embodiment is shown, in which the same pullout guide 4 is used, however, a modified plug 20 is frontally inserted into the track rail 7. In the plug 20, an adjusting wheel 21 is accommodated within a housing, wherein a height adjustment of the drawer 3 can be made via the adjusting wheel 21. The adjusting wheel 21 is accessible from an end face of the plug 20 and the running rail 7 ago.

As in the Figures 5 and 6 can be seen engages a wall 50 of the guide rail 5 in the receptacle on the plug 20, so that the running rail 7 is aligned by the positioning means 11 in the form of the inlet slope 12 on the plug 20 in the horizontal direction laterally to the longitudinal direction of the pullout guide.

In FIG. 7 is a pullout guide 4 on the opposite side FIG. 6 shown. It can be seen that the pullout guide 4 is also provided with a plug 20 and an adjusting wheel 21 for height adjustment. On this side of the drawer 3, however, a wall 50 of the guide rail 5 is not held in the positioning means 11 in the closed position, but in the second receptacle 15. Thus, the wall 50 with game the stopper 20 is positioned, and the alignment of the drawer 3 is made exclusively on the left side, as shown in FIG. 6 is shown.

The plug 20 is in the FIGS. 8A to 8E shown in detail. The plug has a front plate 22 on which projections 23 are formed, which are inserted into the running rail 7. On the plug 20 positioning means 11 are provided with inlet slopes 12 and 13, which are formed on a receptacle for the wall 50. Furthermore, a second receptacle 15 for inserting a wall 50 of a pull-out guide on the opposite side is provided adjacent to the first receptacle. The plug 20 is made of plastic and the adjusting wheel 21 made of plastic or metal and can be assembled from only a few components, in particular, only three components can be provided. As in Figure 8E is shown, the plug 20 may consist of two or more parts, which may preferably be connected by a film hinge. The adjusting wheel 21 is inserted into an opening 24 between two half-shells of the plug 20, wherein the half-shells are then fixed to each other. This makes it possible to produce at the opening 24 and an internal thread on which the adjusting wheel 21 is guided with an external thread. Thus eliminates a complicated screwing the Verstellrades 21 in the internal thread.

In FIG. 9 a further plug 20 'is shown which is modified with respect to the plug 20 with respect to the positioning means 11. Instead of the inlet slopes 12 and 13, two balls 30 are provided which serve to align the wall 50 of the running rail. Between the balls 30, a taper 34 is formed analogous to the taper 14. A first ball 30 forms a first alignment surface 32 while a spaced second ball 30 forms a second alignment surface 33 for locating the wall 50 in a predetermined position between the balls 30 in the closed position.

Instead of the balls 30 in FIG. 9 also rotatably mounted rollers can be used as positioning means 11.

In addition, the inlet slopes 12 and 13 may be formed by sliding elements, for example, in the plug 20 'arranged bolts.

In the illustrated embodiments, the plug 10 or 20 is inserted in each case end face on a running rail 7 a pull-out guide 4. It is Of course, also possible to attach the plug to a guide rail 5, and then to receive a wall of the running rail 7 on the plug 10, 20, so that the running rail 7 is aligned in a closed position.
