Description

The present invention relates to a piece of furniture having the features of the preamble of claim 1.

The EP 1 858 370 discloses a Selbsteinzugsvorrichtung for movable furniture parts, in particular sliding doors, in which a power storage when opening clamped and used in a closing operation as a pulling-in aid to move the sliding door in the final closed position. In order to couple the self-closing device with a sliding door, an activator is provided which is movable along a guide track on a housing and coupled on the one hand with the energy storage and on the other hand with an adapter which can engage with a driver attached to the sliding door. The driver is movable together with the sliding door, and the Selbsteinzugsvorrichtung is fixed with a housing to a furniture body. Such Selbsteinzugsvorrichtungen have proven to move the sliding door in the closed position. In the case of a sliding door, however, there is the problem that it can also strike in the opening direction opposite to the furniture body or against an at least second sliding door and the user does not move the sliding doors to a fully open position to avoid expected impact noise or rebound reactions, so that the interior of the Furniture carcass is not completely accessible. To remedy the problem remedy, the Selbsteinzugsvorrichtungen described were additionally mounted in the opening direction of the furniture body depending on the door width, in turn, then an additional self-closing device in the opening direction is required for each sliding door. Furthermore, however, there is the problem of impact noise between two sliding doors, which are no longer in engagement with the above-described self-closing devices when reaching the maximum intended coverage and the backup against rebound reactions in the collision.

The EP 2 267 260 A1 discloses a damping and extension device for two relative to each other sliding furniture parts. In this case, a pivot lever on a base element between an unfolded position and a retracted position is pivotable, and acted upon by an energy storage in the direction of the folded position. Further, a damping unit for braking the sliding movement is provided on the base member, wherein an actuating element is fixed to the front side of a sliding door to move with the pivot lever on a rear side of the other sliding door.

The DE 20 2009 014 882 U1 discloses a fitting for two sliding door leaves, the first running part for a rear and a second running part for a front sliding door leaf, each running part has a fixed to a sliding door leaf roller carrier and an activator for actuating a closing aid for the respective sliding door leaf.

It is therefore an object of the present invention to provide a piece of furniture with a device for positioning two sliding doors, which provides for improved handling of the sliding doors during an opening movement and for an optimized positioning of the sliding doors relative to one another or in an open position.

This object is achieved with a piece of furniture with the features of claim 1.

According to the invention, a self-closing mechanism is provided on a first sliding door, which has a carrier which is biased by a force accumulator in one direction and can be locked in a position with tensioned energy accumulator, wherein the self-feeder can be coupled with a component fixed to the second sliding door is to move to a final position after unlocking the driver, the second sliding door relative to the first sliding door. As a result, a positioning of the sliding doors no longer takes place by a self-closing, which acts between a stationary furniture body and a movable sliding door, but the self-closing acts directly between two mutually movable sliding doors. Thereby, the self-retraction can be effective regardless of whether the first sliding door or the second sliding door is moved to an open position. It must not be provided for the sliding doors two separate self-retraction, but with a single self-closing in the opening position respectively moved sliding door can be retracted into an end position on the self-closing. This facilitates assembly, since the self-closing is fixed only to the first sliding door and no alignment must be made relative to a furniture body.

In addition, costs are minimized, since only a Selbsteinzugsvorrichtung is required with the same range of functions, since according to conventional design analogous to the prior art for task performance so far three devices are used.

In a preferred embodiment, the two sliding doors are arranged in a substantially overlapping position in the end position. In a Such position maximizes access to the interior of a furniture carcass or other opening to provide optimum access. Preferably, the self-closing mechanism has a damper in order to decelerate the travel movement into the end position. Such dampers can be designed as linear dampers, in particular fluid dampers, rotary dampers or friction dampers.

The self-closing can be coupled to a running part or a guide part of a sliding door fitting, in particular a trained as a bent metal sheet running part, which has sufficient strength to transmit corresponding braking forces or retraction forces of Selbsteinzuges on the sliding door. This has the advantage that for coupling the self-closing no additional component, such as an activator, must be provided, but an already existing running part of a sliding door fitting is used for coupling with the self-closing. In this case, the end faces of the running part act as contact surfaces with corresponding stop surfaces of the driver together by being encompassed by the driver. But the coupling can also be done with a guide part, which leads the sliding door near the opposite end face to the track in a plane to the front of the furniture body.

The self-closing device preferably has a coupling element, which can be coupled to the second sliding door, preferably as a running part, and the driver of the self-closing device can be unlocked via the coupling element. Here, the coupling element may comprise a stop and a pivotable lever, wherein the component is held on the second sliding door in an engaged position between the pivotable lever and the stop. Other mechanisms for coupling the coupling element with the component can be used. By embracing the component both forces in the opening and closing direction can be transmitted. The coupling element may for example be designed as a slide which is movable along a first guide track on a housing of the self-closing. The first guideway here consists of a beveled guideway section, which is followed by a linear guideway section. In a preferred embodiment, the guideway terminates with an angled guideway section, which serves to protect the coupling element and the pivotable lever from being damaged in case of incorrect operation or malfunction.

Preferably, the force accumulator is fixed at one end to the housing of the self-closing mechanism and at another end to the driver, wherein the coupling element can be moved along the guide by the force accumulator during a self-closing. The energy accumulator thus moves the coupling element within the housing of the self-closing, wherein the coupling element is coupled to the component and then moves the second sliding door relative to the first sliding door.

On the housing of the self-closing a guide track is preferably formed with an angled end portion along which the driver is movable, wherein in a position with tensioned energy storage, the coupling element locks the driver on the end portion. As a result, a reliable locking of the energy accumulator is ensured in the cocked position, which can be solved again only when moving the coupling element. For this purpose, means for unlocking the driver can be provided on the coupling element, which unlock the driver when moving the coupling element, for which purpose, for example, a run-on slope is integrally formed on the coupling element to move the driver along the angled end portion.

The damper of the self-retraction is preferably arranged so that movement of the coupling element is damped relative to the housing, wherein preferably only a linear movement between the coupling element and the housing occurs, so that lateral forces are avoided. According to the invention, a piece of furniture with at least two sliding doors is provided, which can be moved in different planes, and for which a movement of the sliding doors, at least in one partial area, is made possible by a device for positioning two sliding doors. Preferably, the device is used on the one hand for positioning the two sliding doors in an opening area in which either the first or second sliding door is in an open position and is moved via the self-closing in the maximum opening position as the end position. On the other hand, the device is used for controlled self-closing and the positioning of a first to a second sliding door when these sliding doors move towards each other and run the risk of colliding with each other.

For a particularly compact design, which does not appear optically, the device is arranged on the rear sliding door, on the side facing a furniture carcass side. As a result, the device remains invisible from the outside in the closed position of the sliding doors.

In a further embodiment, the first and / or the second sliding door are held in a closed position via a self-closing in the closed position. The holding forces of the self-closing are greater than the holding forces for positioning the sliding doors. Therefore, if one of the two sliding doors is in a maximum open position and the self-closing mechanism has moved the sliding door into the end position, this sliding door can be moved again in the closing direction against the force of the energy storage device, without dragging the other sliding door, because the holding forces of the self-closing for the Closed position are greater than the holding forces of the device for positioning the two sliding doors, so that a one-hand operation is possible. Only when the device for positioning the two sliding doors is engaged, while neither of the two self-closing mechanisms are in engagement with the two sliding doors, the two sliding doors must be pulled apart in different directions in order to release the device for positioning the two sliding doors.

The device for positioning two sliding doors is used for furniture having two, three or more sliding doors. It is not according to the invention also possible to use the device for positioning two sliding doors for room dividers or other sliding elements. In addition, the sliding doors can also be designed as Faltschiebetüren or folding sliding doors and are generally referred to below as "sliding doors".

A piece of furniture 1 comprises a cabinet-shaped furniture body 2, on which a first rear sliding door 3 and a second front sliding door 4 are provided. The sliding doors 3 and 4 are movably held on the furniture body 2 along a running rail which is arranged on top of the furniture body 2, wherein the sliding doors 3 and 4 are arranged in different planes parallel to the front side of the furniture body 2. The front sliding door 4 is held by two U-shaped running parts 5 on a running rail on the furniture body 2, wherein the U-shaped running parts 5, the rear sliding doors 3 overlap. The gap between the running parts 5, which results from the offset of the planes is provided against penetrating dirt with a cover.

While in FIG. 1 a furniture 1 with two sliding doors 3 and 4 is shown FIG. 2 a piece of furniture 1 'with a modified furniture body 2', are provided on the three sliding doors, namely two rear sliding doors 3 in a plane parallel to the furniture body 2 'and a front sliding door 4, in a parallel preceding another level. The front sliding door 4 is held by U-shaped running parts 5 on a running rail on the furniture body 1 ', wherein the U-shaped running parts 5 overlap the rear sliding doors 3. In a closed position, the rear sliding doors 3 are each held in the furniture body 2 'behind the running rail and therefore not visible self-closing and the middle front sliding door 4 via an outside on the furniture body 2' arranged collection device 6. In the FIG. 3 the right rear sliding door 3 is shown in the open position, wherein on the right of the running rail of the elongated opening through which the Self-closing the locking device with the right running part of the rear sliding door 3 cooperates, can be seen.

For the purposes of the application, a "self-closing mechanism" is understood to mean an assembly unit by means of which a movable furniture part can be moved to an end position via a force store. Such a self-feeder is for example from the EP 1 858 370 known and can be fixed to the furniture body 2 or 2 'to fix each one of the sliding doors 3 in a closed position.

In FIG. 4A is the furniture 1 'of the FIG. 3 shown in detail, wherein the right rear sliding door 3 has been moved in the opening direction. The middle sliding door 4 is held by the retracting device 6 in the closed center position, wherein the retracting device 6 holds the right running part 5 in the closed position via a driver 8 by the right running part 5 is coupled to the driver 8 via an additionally mounted activation element 7 , When a certain force in the direction of travel is exceeded, the middle sliding door 4 can be moved from the closed position to an open position.

A device for positioning two sliding doors 3 and 4 is according to the invention at the rear first sliding door 3 and has a stop 9 which is movable against a first end face 37 of the running part 5 of the middle sliding door 4. Thereby, the rear sliding door 3 can be coupled to the front second sliding door 4 via the positioning device to move the rear sliding door 3 to an end position, in particular, the full opening position in which the sliding doors 3 and 4 substantially overlap each other.

In FIG. 4B is both the furniture 1 of the invention FIG. 1 as well as the furniture 1 'of the invention FIG. 2 showing in the opening direction moving left sliding door 3 in detail, which also have a device for positioning two sliding doors, wherein a stop 9 is moved against a second end face 37 of the other running part 5 of the front sliding door 4 and the running part 5 between the stop 9 and a pivotable lever 10 is arranged, so that the two sliding doors 3 and 4 are coupled together by the device for positioning. The stop 9 and the pivotable lever 10 are hinged to each other to form a unit. The left sliding door 3 on the furniture body 2 'can by the device for positioning two sliding doors in an end position, in particular the maximum opening position, be moved by the two sliding doors 3 and 4 substantially overlap each other. The respective other rear sliding door 3 must then be in the closed position in order to avoid a collision, since both sliding doors 3 are in one plane.

In the FIGS. 5A to 5D the sliding doors 3 and 4 are shown with respect to the rear side, but without the furniture body 2, 2 'and a running rail mounted on the furniture body 2 or 2', wherein an opening operation of one of the sliding doors 3 or 4 is shown. The opening operation for the sliding door 4 will be described, and the opening operation will be the same for the left sliding door 3 when it is moved relative to the sliding door 4, since the device for positioning two sliding doors 3 and 4 will only move the two sliding doors 3 relatively and 4 is influenced to each other.

In FIG. 5A is the sliding door 4 in an opening movement to cover the fixed sliding door 3, wherein the sliding door 4 is held on two running parts 5, which are guided over rollers 12 on a track of a track rail. The first rear sliding door 3 is also held on two running parts 13, which are guided via rollers 14 at a further track of the track rail, wherein the raceways are arranged adjacent to the track rail in different planes. On the running part 5, a slider 11 is provided as a lifting-out, to avoid that the sliding door 4 can be removed from the track unintentionally.

When the front sliding door 4 is moved in the opening direction, passes the U-shaped running part 5 with its end face 37 against a stop 9 of the device for positioning the sliding doors, as shown in FIG FIG. 5B is shown. By the movement of the running part 5 to the right, the stop 9 is also moved relative to a fixed to the sliding door 3 housing 15 of the device for positioning the sliding doors to the right, whereby a lever 10 is pivoted, the running part 5 seen in the direction of travel at a rear engages like this in FIG. 5C is shown. Thus, a coupling between the first sliding door 3 and the second sliding door 4 is made by embracing the running part 5 on the stop 9 and the lever 10, and the device for positioning the sliding doors can now move the front sliding door 4 in the maximum opening position, such as this in FIG. 5D is shown. In the maximum opening position, the sliding doors 3 and 4 are in a substantially overlapping position, the end faces of the sliding doors 3 and 4 need not necessarily be aligned flush in the direction of travel, but a large extent Cover the front sides for making an opening on the furniture body 2 or 2 'is sufficient.
Furthermore, the device for positioning the sliding doors to the fact that the first sliding door 3 with a controlled retraction movement can always take a reproducible distance to the second sliding door 4 when the two sliding doors 3, 4 approach. Thus, a collision of both sliding doors is also effectively prevented. The associated impact noise or rebound reactions are avoided, since the running part 5 in the end position on both end faces 37, as described above, from the stop 9 and the lever 10 is included.

The function of the device for positioning is based on the FIGS. 6A to 6E explained in more detail, the opening process of FIGS. 5A to 5D show again, but in a sectional view, in which the housing 15 of the device for positioning the sliding doors is shown open.

In FIG. 6A moves the running part 5 with the front sliding door 4 in the opening direction to the stop 9 of the device for positioning the sliding doors. The device for positioning the sliding doors comprises a housing 15, which is at the back of the rear sliding door 3 in the clear area above the track, that is not above the top of the sliding door 3 protruding, defined, wherein on the housing 15, a coupling element 16 guided linearly displaceable is formed integrally with the stopper 9, wherein the stopper 9 may also be fixedly connected to the coupling element 16. However, this stop 9 extends beyond the top of the sliding door 3 so far that it can safely cover the end face 37 of the running part 5. When the coupling member 16 is linearly moved along the housing 15, this actuates a damper having a damper housing 17 and a piston rod 18. The damper is fixed between a holder on the housing 15 and a holder on the coupling element 16 and thus can decelerate upon impact of the running part 5 on the stop 9, a movement of the coupling element 16 relative to the housing 15, which thus also the movement of the front Sliding door 4 brakes, which impinges on the stop 9 by means of the running part 5.

Further, in the housing 15, a force accumulator 19 in the form of a spring, in particular a tension spring, shown, which is fixed with one end 21 to the housing 15. The opposite end of the force accumulator 19 is held on a driver 20 which along a guide track 22 on the housing 15th is movable. The driver 20 is in the position of FIG. 6A shown in a locked position in which the energy storage 19 is tensioned.

Now moves the running part 5 in the opening direction, it strikes with an end face 37 on the stop 9 of the coupling element 16, as in FIG. 6B is shown. Due to the kinetic energy of the stop 9 is slightly moved to the right, and the in FIG. 6C shown position is reached. By moving the coupling element 16 of the coupled thereto pivotable lever 10 from its rest position in FIG. 6B pivots and engages behind the running part 5, so that this is now held at its end faces 37 between the stop 9 and the pivotable lever 10.

Only after concerns of the lever 10 on the running part 5 by the linear displacement of the coupling element 16 is an unlocking of the driver 20 which is moved by the movement of the coupling element 16 in an unlocked position, for which purpose the driver 20 by the contact with the run-on slope 24th is raised slightly, as in FIG. 6D is shown. In this position, the driver 20 is released from the locked position and can be moved linearly to the right by the energy storage device 19, whereby the coupling element 16 relative to the housing 15 and the sliding door 3 also to the right in FIG. 6D is moved. Due to the relative movement of the coupling element 16 to the housing 15, the damper is compressed, so that the piston rod 18 enters the damper housing 17 and decelerates the movement of the coupling element 16.

The retraction movement introduced thereby continues until the coupling element 16 reaches the end of a guideway 22 or another component strikes against a stop, so that an end position is reached. The energy accumulator 19 has thus moved the coupling element 16 against the force of the damper and moves the sliding door 4 in an end position corresponding to the maximum opening position of the sliding door 4 in this case. Since only a relative movement of the sliding doors 3 and 4 is influenced by the device for positioning the sliding doors 3 and 4, the sliding door 3 could just as well be moved in the opening direction, while the front sliding door 4 is arranged stationary, without the movement of the FIGS. 6A to 6E Differences in the relative movement result to each other.

If the front sliding door 4 is to be moved again in the closing direction from the maximum opening position or end position, the rear one becomes Sliding door 3 by a self-closing device, which is fixed to the furniture body 2, 2 ', held in the closed position. The holding forces of the self-closing device are greater than the forces that must be introduced for tensioning the force accumulator 19 of the device for positioning the sliding doors 3 and 4. As a result, by pulling on the sliding door 4, the energy accumulator 19 can be tensioned without the sliding door 3 being moved. When moving the sliding door 4 in the closing direction is a movement starting from FIG. 6E up to the in FIG. 6A shown position, wherein the energy storage device 19 is again transferred to a cocked and locked position.

The locking and unlocking of the driver 20 is in the FIGS. 7A to 7C again shown in detail. In the housing 15 is a guide track 22 in both halves of the housing 15 (see also FIG. 8 ), which has an angled end portion 23. In these guideways 22 a continuous pin 26 of the driver 20 is guided, so that no unilateral forces occur by the two-sided leadership. In the locked position, the pin 26 abuts against the sides of the angled end portions 23 facing the force accumulator 19 by the force of the tensioned force accumulator 19, and movement of the pin 26 out of the angled end portions 23 is prevented by a portion 35 of the coupling element 16. which rests in a slot of the driver 20 from above on the continuous pin 26, as shown in FIG FIG. 7A is shown.

If now the coupling element 16 is displaced by the impact of the running part 5 on the stop 9, the coupling element 16 moves from the position shown in Figure 7A to the right, so that a run-on slope 24 from below impinges on the continuous pin 26, which below a receptacle 25 is arranged. Thereby, the pin 26 can be moved from the end portion 23 upwards into the receptacle 25, as shown in FIG FIG. 7B is shown. By the displacement of the pin 26 by means of the run-on slope 24, the driver 20 is unlocked and passes from the end portion 23 in the straight portion of the guide rail 22. In this straight portion of the guide track 22, the driver 20 together with the coupling element 16 by the force of the energy accumulator 19 are moved to the end position, as in FIG. 7C is shown. The guide over only one pin 26 in the guideway 22 has the further advantage that the driver 20 can always align during the process in the final position to the end 21 of the energy accumulator 19 and thus largely transverse forces are avoided additionally caused by the central arrangement of the pin 22 of the receptacle 27 for extending the longitudinal axis of the energy accumulator 19.

When the closing movement described above, the coupling element 16 from the end position according to FIG. 7C moved back to the left in the closing direction, so the pin 26 moves through the insert in the receptacle 25 along the guide track 22 to the angled end portion 23, and then takes place by the contact with the outer radius of the angled end portion 23, a relative movement between the coupling member 16th and the driver 20 from the receptacle 25 down, so that the pin 26 is locked again to the end portion 23 through the portion 35, as shown in FIG. 7A is shown.

In FIG. 8 the device for positioning two sliding doors 3 and 4 is shown in an exploded view. The device comprises a housing 15, which is formed from two shell-shaped housing parts, wherein a guide track 22 with an angled end section 23 is formed on both housing parts. In these two guideways 22 and the angled end portions 23 of the housing 15, a pin 26 of the driver 20 is guided in each case, wherein it is also possible to provide only one guide track on the housing 15. Due to the two-sided leadership of the driver 20 tilting is better avoided. On the driver 20, a receptacle 27 for holding one end of the force accumulator 19 is provided.

The damper with the damper housing 17 and the piston rod 18 can be placed on the housing 15 and the coupling element 16 in corresponding receptacles and optionally locked. As damper fluid damper, in particular hydraulic or pneumatic damper, can be used. It is also possible to connect several dampers in parallel or in series, as long as heavy sliding doors 3 or 4 are to be braked.

On the coupling element 16, the stop 9 is formed on one side, which protrudes upward from the housing 15. On the opposite side of the coupling plate 16, the stop bevel 24 for unlocking the driver 20 and the adjoining receptacle 25 is formed, wherein adjacent to the receptacle 25, a portion 35 for locking the driver 20 is formed on the angled end portion 23.

On the coupling element 16 is further a pivot axis 28, in particular in the form of an opening formed, into which a pin engages the pivotable lever 10 so that it is pivotally mounted on the coupling element 16. It is also possible to pivot the lever 10 by a cam guide or other means to support the coupling element 16. On the lever 10, an actuating stop 29 is formed, which is movable against a stop 36 on the housing 15 when the stopper 9 is moved from its initial position by the running part 5 along a guide track 38. By the linear method of the pivotable lever 10 together with the coupling element 16, the stopper 36 presses against the actuating stop 29 and pivots the lever 10 upwards to encompass the end faces 37 of the running part 5.

In Figures 11A and 11B a modified lever 10 'is shown, which is to replace the lever 10. In order to overcome an automatic maladjustment, ie when already the retraction movement took place without previously a running part 5 was embraced at the end faces, as shown in the FIGS. 5C and 5D is shown, the lever 10 'can be used. The modified lever 10 'arranged on a pivot axis 28 on the coupling element 16' is replaced by a further force store 39, eg in the form of a compression spring, shown in FIGS. 11A and 11B or a torsion spring, shown in FIGS Figures 12A and 12B , supported on the coupling element 16 '. The caused by the force accumulator 39 Ausschwenkwinkel the lever 10 'is, for example, by a laterally arranged control pin 40 on the lever 10' at a further control cam 41, which is laterally on the housing 15 'is limited, whereby the pivoting range of the lever 10', dependent is controlled by the displacement of the coupling element 16 'to the housing 15', shown in the Figures 11C and 11D or in the Figures 12C and 12D , Due to the linear displacement between the coupling element 16 'with the housing 15' through the running part 5 of the control pin 40 runs on the control cam 41, by the force accumulator 39 fitting, from, wherein the lever 10 'is pivoted from an in-position to the engaged position, wherein ultimately the running part 5, as described above, between the stop 9 and the lever 10 'at both end faces 37 is included.

In FIG. 9 the device for positioning the sliding doors during assembly is shown. In order to be able to effect a predetermined opening position or a predetermined positioning of the two sliding doors 3, 4 relative to each other by means of the device, it must be mounted exactly on the sliding door 3. For this purpose, the housing 15 on the one hand to the running part 13 and on the other hand an assembly aid 31 are aligned. The housing 15 includes for this purpose, as in FIG. 10 is shown as an example, openings 30, engage in the head portions 32 of the mounting aid 31. The mounting aid 31 is attached to an end face of the housing 15 and has an upwardly projecting tab 33, on which an angled web 34 is formed. The web 34 is placed on top of the sliding door 3, so that an optimal vertical alignment of the housing 15 is achieved. As a result, an inclination of the housing 15 is avoided during assembly.

In the illustrated embodiment, the device for positioning two sliding doors 3 or 4 is fixed to the back of the rear sliding door 3, irrespective of whether the furniture 1 has two sliding doors 3 or 4 or three sliding doors according to FIG FIG. 2 having.
