Description

The present invention relates to a drawer slide, in particular for drawers, with a fixable on a furniture body guide rail to which a running rail is mounted directly or at least over a middle rail movable, and on the running rail an activator is arranged with a driver of a locking mechanism for holding the running rail can be coupled in a closed position.

From the EP 1 845 821 a device for opening and closing of drawers is known in which a latching mechanism, the drawer is held in the closed position. For this purpose, a coupled with a running rail driver is provided, which is guided via a rod on a control cam. The control cam is formed in a housing which is displaceable via a setting wheel in order to position the front panel of a drawer mounted on the drawer guide. The adjustment process is complicated because the locking mechanism is arranged in the furniture body and the adjustment and orientation of the front panel can be checked only in the closed position.
WO 2007/068019 shows another device for opening and closing drawers.

It is therefore an object of the present invention to sharpen a pullout guide that can lock a drawer in a closed position, the alignment of a front panel is done by simple means.

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

According to the invention, the position of the activator relative to the running rail in the direction of movement of the running rail is adjustable by a rotatable actuating element. This makes it possible to arrange the locking mechanism for holding a running rail or a drawer stationary in a closed position, since the alignment of a front panel takes place via the positioning of the activator. The activator is connected to the running rail, so that the adjustment can also be done with the slide rail pulled out, which greatly simplifies the accessibility. The adjustment can be made steplessly over the rotatable actuator, which is self-locking and allows precise positioning. A scaling can facilitate the positioning of the activator on the opposite pullout guides, in particular, the adjusted position of the activator is better visualized.

According to one embodiment, an eccentric is provided for adjusting the activator. The eccentric forms a rotatable actuating element, via which the positioning of the activator takes place. Alternatively, a spindle, a pivot lever or other actuator for adjusting the activator can be used.

In a further embodiment, a gear drive is provided with a corresponding rack for adjusting the activator. The pinion is self-locking to avoid an adjustment of the activator after adjustment. The setting of the adjustment takes place by a Feitigungsverfahren, for example, wobble.

Furthermore, a worm drive with segments can serve to adjust the activator. The worm drive is designed to be self-locking to prevent adjustment of the activator after adjustment.

In addition, the adjustment of the activator can also be done by loosening and tightening a fastener. In the released state, the activator can then be moved to the desired position.

In a further embodiment, the activator is bolted to the base plate or fixed by a toggle lever as in a quick release of an impeller on the bike. By loosening the detection, the activator can be moved on the base plate.

Base plate and activator are designed as inclined plane and provided for example with a toothing. Due to the gearing, the positioning is rastered and secured against displacement. At the same time twisting of the component by the toothing is not possible.

The embodiments described above can also be combined with each other. Thus, the eccentric variant can be executed with a toothing on the activator and the base plate, or the rack variant can also be provided with the screening.

For a compact construction of the activator is preferably plate-shaped and has a recess which is penetrated by the eccentric. As a result, the adjusting mechanism can be produced with only a few components.

The activator preferably comprises at least one guide element, by means of which the activator is displaceably mounted in the longitudinal direction of the running rail. The guide element may be formed as a slot, projection, rib, groove or other profiling, in particular, the guide element is integrally formed with the activator.

In a preferred embodiment, the eccentric on an axis of rotation, which is mounted in an opening of a base plate or the track rail. The axis of rotation may be formed as a pin which can be inserted into a corresponding circular opening of the base plate or the running rail and provides the rotatable mounting. In this case, the pin may be arranged by clamping in the opening in order not to make the rotational movement too smooth, so that an unintentional adjusting movement can be safely avoided. Further, in a clamping fixing the eccentric ensure a backup of the activator, which is indeed arranged adjustable in the direction of movement of the running rail, but is held between a disc of the eccentric and the running rail. The activator can then have a downwardly projecting projection which can be inserted into a receptacle of the driver. This results in a particularly compact design of the pullout guide.

If the adjusting device for positioning the activator is to be produced as a prefabricated unit, a base plate is preferably fixed to the running rail, which has at least one slot in the longitudinal direction for guiding the activator. Then the base plate, the activator and the eccentric can be delivered as a prefabricated unit.

According to the invention, a piece of furniture is also provided which has a furniture carcass and at least one drawer which is movably mounted via two pull-out guides according to the invention.

A pullout guide 1 comprises a guide rail 2 which can be mounted on a furniture carcass and on which a running rail 3 is displaceably mounted via rolling bodies. To form a full extension can be provided between the running rail 3 and the guide rail 2 and one or more center rails. On the running rail 3, an activator 4 is set, which provides for a coupling with a latching mechanism 5, by means of which a coupled to the running rail 3 thrust element, in particular a drawer, is locked in a closed position. The latching mechanism 5 comprises a housing 6 which is fixed to the guide rail 2 and on which a cartridge 7 is provided with a control cam and a spring, by means of which a driver 8 is locked in a predetermined closed position. The latching mechanism 5 can be designed as it is in the DE 20 2008 013 229 . DE 20 2008 013 230 or DE 20 2009 001 516 is disclosed. With regard to the latching mechanism 5, the disclosure content is included in this application.

As in FIG. 2 can be seen, the driver 8, which is guided along a curved path on the housing 6, a receptacle with a front web 9 and a rear web 11, between which a lower projection 10 of the activator 4 is inserted. During a movement of the driver 8 along the curved path, this is pivoted at a bent end portion, so that the projection 10 can be moved over the front web 9 in order to move the running rail 3 in the opening direction. During a closing movement of the projection 10 abuts against the rear web 11, so that the activator 4 and the driver 8 are coupled again. The driver 8 is latched in a closed position by the latching mechanism 5, wherein in a closed position, a front panel of a drawer is spaced from the furniture body. By pressing the front panel in the furniture body of the locking mechanism 5 is unlocked and the running rail 3 can be pressed together with the drawer by the force of a spring in the opening direction.

In order to make the alignment of a front panel in the closed position, the activator 4 is held via an eccentric 12 adjustable on the running rail 3. The eccentric 12 can move the activator 4 in the longitudinal direction of the running rail 3 by a rotational movement.

As in FIG. 3 is shown, is located on the running rail 3, a base plate 13 to which the activator 4 and the eccentric 12 are held. The base plate 13 comprises a circular opening 14 and two spaced apart elongated holes 15 whose longitudinal extent is aligned parallel to the longitudinal direction of the running rail 3 ( FIG. 4 ).

As in the FIGS. 5A and 5B is shown, the substantially plate-shaped activator 4 has a recess 16 which is designed rectangular with rounded corners. From the activator 4 stand out two spaced apart projections 17, which are inserted into the slots 15 of the base plate 13. About the projections 17 and the slots 15 a guide of the activator 4 is ensured in the direction of movement of the running rail 3.

As in the Figures 6A and 6B is shown, the eccentric 12 comprises a pin-shaped pivot axis 18 which is insertable into the opening 14. The axis of rotation 18 is connected to an eccentric disc 19, which is inserted into the recess 16 of the activator 4 and provides a rotational movement of the eccentric 12 for a displacement movement of the activator 4. Finer is formed on the eccentric 12, a disc 20 which has a larger diameter than the eccentric disc 19. Furthermore, the disc 20 has a tool holder 21. Through the disc 20, the activator 4 is secured against unintentional removal from the base plate 13. The eccentric 12 can be clamped at the circular opening 14 of the base plate 13.

In FIG. 7 a modified embodiment for the adjustment mechanism is shown in which the activator 4 and the eccentric 12 are formed as in the previous embodiment. Instead of the provision of a base plate 13, a running rail 3 'is provided, which has a leg 13' on which a circular opening 14 and elongated holes 15 are formed, as is the case in the first embodiment. As a result, the activator 4 is guided directly on the running rail 3 'and can be adjusted by a rotational movement of the eccentric 12.

In the FIGS. 8A to 8C different positions of the activator 4 relative to the running rail 3 are shown. In Figure 8A the activator 4 is arranged in a substantially central position. If a front panel is to be moved closer to the furniture body, the eccentric 12 is rotated, so that the activator 4 is moved along the slots 15 until the in FIG. 8B shown position is reached. As a result, the running rail 3 is retracted slightly further into the furniture body in the closed position. Alternatively, the front panel can be further moved out of the furniture body by the eccentric 12 is moved in the opposite direction, so that the activator 4, the in FIG. 8C shown position occupies.

In FIG. 9 is a gear drive 22 with a korespondierenden rack 23 for adjusting the activator 4 'is provided. The gear drive 22 is designed to be self-locking in order to avoid an adjustment of the activator 4 'after the adjustment. The setting of the base plate 13 'on the running rail 3 is carried out by a manufacturing process, for example, wobble.

The FIG. 10 shows the adjustment of the activator 4 "also done by loosening and tightening a fastener 24. In the released state, the activator 4" can then be moved to the desired position. A base plate 13 "may, for example, be integrally connected to the running rail 3.

In the FIG. 11 are a base plate 13 '' and an activator 4 '' provided with a toothing 25. By the teeth 25, the positioning is rasterized and secured against displacement. At the same time twisting of the component by the teeth 25 is not possible. The determination on the desired position by tightening the fastener 24th

In the illustrated embodiment, the activator 4 is adjustable via an eccentric 12. Of course, it is also possible to modify the eccentric or make an adjustment via a pivot lever. In addition, the leadership of the activator 4 in the longitudinal direction of the running rail 3 via other mechanical means, in particular ribs, grooves, profilings, slots or other elements.
