Description

Device for positioning two sliding doors and piece of furniture

Technical Field

The invention relates to a device for positioning two sliding doors relative to one another, in particular for a piece of furniture, comprising a first sliding door which can be moved along a first rail and a second sliding door which can be moved along a second rail adjacent to the first rail, wherein a self-retractor is provided on the first sliding door, which self-retractor has a drive which can be moved along a guide path, which drive is pretensioned by a force accumulator in one direction and can be locked in a position in which the force accumulator is tensioned.

Background

EP1858370 discloses a self-retracting device for a movable furniture part, in particular for a sliding door, wherein an energy store is tensioned during the opening process and serves as a retraction aid during the closing process to move the sliding door into a final closed position. In order to couple the self-retracting device to the sliding door, an actuator is provided, which is movable along a guide path on the housing and is coupled on one side to the accumulator and on the other side to an adapter which can engage with a drive fastened on the sliding door. The actuator is movable with the sliding door and the self-retracting device is fixed with the housing on the furniture body. Such self-retracting devices have proven themselves for moving sliding doors into a closed position. However, there is a problem in the sliding door: it may also strike the furniture body, or at least a second sliding door, on the opposite side in the opening direction, and the user cannot move the sliding door to the fully open position in order to avoid the expected striking noise and/or rebound reaction, and thus cannot fully utilize the interior of the furniture body. In order to provide a remedy to this problem, the described self-retracting devices are also mounted on the furniture carcass according to the door width in the opening direction, in which case additional self-retracting devices are required for each sliding door. However, the following problems still remain: the noise of impact between two sliding doors which no longer engage the self-retracting device described above when the maximum set overlap is reached, and safety concerns regarding the reaction to rebound upon impact.

Disclosure of Invention

It is therefore an object of the present invention to provide a device for positioning two sliding doors which ensures improved operation of the sliding doors during opening movement and optimal positioning of the sliding doors relative to each other or in the open position.

This object is achieved by a device for positioning two sliding doors having the features of claim 1.

According to the invention, a self-retractor is provided on the first sliding door, which has a drive which is movable along a guide path, is pretensioned in one direction by an accumulator and can be locked in a position in which the accumulator is in the tensioned state, wherein the self-retractor can be coupled to a component which is fixed to the second sliding door in order to move the second sliding door into an end position relative to the first sliding door after the drive has been unlocked. The positioning of the sliding door is therefore no longer achieved by the self-retractor acting between the fixed furniture body and the movable sliding door, but rather the self-retractor acts directly between the two sliding doors which are movable relative to one another. Therefore, the self-retractor can function regardless of whether the first sliding door or the second sliding door is moved to the open position. It is not necessary to provide two separate self-retractors for the sliding door, but each sliding door that is moved to the open position can be retracted to the end position by the self-retractors using a single self-retractor. This facilitates installation, since the self-retractor only needs to be fixed to the first sliding door and does not have to be aligned with respect to the furniture body.

Furthermore, since only one self-retracting device having the same functional range is required, the cost is minimized because three devices have been used so far to achieve similar objects to the prior art according to the conventional structure.

In a preferred embodiment, in the end position, the two sliding doors are arranged in a substantially overlapping position. In such a position, the space of the internal utilization or another opening of the furniture body is maximized, thereby providing an optimal utilization.

The self-retractor preferably has a damper to slow down the movement towards the end position. Such a damper can be designed as a linear damper, in particular as a fluid damper, a rotary damper or a friction damper.

The self-retractor can preferably be coupled to a sliding part of the sliding door fitting, in particular a sliding part formed as a bent sheet metal, which has sufficient strength to transmit a corresponding braking or retracting force of the self-retractor to the sliding door. This has the following advantages: it is not necessary to provide an additional component (for example, an actuator) for coupling the self-retractor, but rather a sliding component of the sliding door fitting, which is provided in any case, is used for connecting to the self-retractor. In this case, the end faces of the slide elements interact as contact faces with corresponding stop faces of the drive, so that they are enclosed by the drive. The coupling can also be performed in the same way using guide members which guide the sliding door close to the opposite end faces of the rail in a plane relative to the front side of the furniture body.

The self-retractor preferably has a coupling element which can be coupled with a component, preferably formed as a sliding component, on the second sliding door, and the drive of the self-retractor can be unlocked via the coupling element. To this end, the coupling element may have a stop and a pivotable lever, wherein the component on the second sliding door is held in an engaged position between the pivotable lever and the stop. Other mechanisms may also be used to couple the coupling element to the component. Since the parts are enclosed, the force can be transmitted in the opening direction as well as in the closing direction. The coupling element may for example be formed as a slider which is movable along a first guide path on the housing of the self-retractor. In this case, the first guide path is composed of a corner guide path section connected with the linear guide path section. In a preferred embodiment, the guide path terminates in a corner guide path section for protecting the coupling element and the pivotable lever from damage in case of faulty operation or malfunction.

The energy store is preferably fastened at one end to the housing of the self-retracting device and at the other end to the drive, wherein the coupling element is movable by the energy store along the guide during self-retraction. The accumulator thus moves the coupling element inside the housing of the self-retractor, wherein the coupling element is coupled to the component, and then moves the second sliding door relative to the first sliding door.

Preferably, a guide path with a corner end is formed on the housing of the self-retractor, along which guide path the drive is movable, wherein the coupling element locks the drive at the end in a position in which the accumulator is in the tensioned state. This ensures a secure locking of the energy store in the tensioned position, which can only be released again if the coupling element is moved. For this purpose, a means for unlocking the drive can be provided on the coupling element, which means unlocks the drive when the coupling element is moved, wherein for this purpose, for example, an entry bevel is formed on the coupling element in order to move the drive along the corner end.

The damper of the self-retractor is preferably arranged such that the movement of the coupling element relative to the housing is damped, wherein preferably only a linear movement between the coupling element and the housing occurs, so that transverse forces are avoided.

According to the invention, there is also provided an item of furniture having at least two sliding doors which are movable in different planes and the movement of which, at least to a partial extent, can be effected via means for positioning the two sliding doors. In this case, the device is preferably used on the one hand in an opening range in which the first sliding door or the second sliding door is alternately located in an opening position and is moved via the self-retractor to a maximum opening position as an end position. On the other hand, the device is used for controlled self-retraction and positioning of a first sliding door relative to a second sliding door when the sliding doors are moved towards each other and are at risk of colliding with each other.

For a particularly compact construction which is not visible, the device is preferably arranged on the side of the rear sliding door facing the furniture carcass. In the closed position of the sliding door, the device is therefore still not visible from the outside.

In another embodiment, the first sliding door and/or the second sliding door is held in the closed position via a self-retracting device at the closed position. In this case, the holding force of the self-retracting device is greater than the holding force for positioning the sliding door. Therefore, if one of the two sliding doors is located at the maximum opening position and the self-retractor has moved the sliding door to the end position, it is possible to move the sliding door rearward in the closing direction against the force of the accumulator without pulling the other sliding door together, since the holding force of the self-retracting means for the closed position is greater than that of the means for positioning the two sliding doors, making one-handed operation possible. Only when the means for positioning the two sliding doors are engaged, while neither of the two self-retracting devices is engaged with the two sliding doors, must the two sliding doors be pulled apart in a different direction, so that the means for positioning the two sliding doors are disengaged again.

The device for positioning two sliding doors can be used in particular for pieces of furniture having two, three or more sliding doors. However, the device may also be used to position two sliding doors or other sliding elements for a room divider. Furthermore, the sliding door may also be designed as a folding sliding door or as a foldable sliding door, which will generally be referred to as "sliding door" in the following.

Detailed Description

the piece of furniture 1 comprises a cabinet-shaped furniture body 2, on which furniture body 2a first rear sliding door 3 and a second front sliding door 4 are arranged. The sliding doors 3 and 4 are mounted such that they can move on the furniture body 2 along a sliding rail 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. In this case, the front sliding door 4 is held on the sliding rail of the furniture carcass 2 via two U-shaped sliding parts 5, wherein the U-shaped sliding parts 5 overlap the rear sliding door 3. The gap between the gliding parts 5 due to the use of flat surfaces is provided with a cover preventing penetration of dirt.

In fig. 1, a piece of furniture 1 with two sliding doors 3 and 4 is shown, while fig. 2 shows a piece of furniture 1 ' with a modified furniture body 2 ', on which piece of furniture 1 ' three sliding doors are provided, namely: two rear sliding doors 3, in a plane parallel and adjacent to the furniture body 2'; and a front sliding door 4 in another plane parallel to the front. In this case, the front sliding door 4 is held on the sliding rail of the furniture carcass 1' via a U-shaped sliding part 5, wherein the U-shaped sliding part 5 overlaps the rear sliding door 3. In the closed position, the rear sliding doors 3 are respectively held via self-retractors arranged behind said sliding tracks in the furniture body 2 'and thus not visible, and the intermediate front sliding door 4 is held via a retraction device 6 arranged outside the furniture body 2'. In fig. 3, the rear right sliding door 3 is shown in an open position, in which an oval penetration is visible on the right side of the sliding track, through which the self-retractor of the closing device interacts with the right sliding track of the rear sliding door 3.

In the sense of the present application, a "self-retractor" is understood to be a structural unit by means of which a movable furniture part can be moved to an end position via an accumulator. Such self-retractors are known for example from EP1858370 and can be fixed on the furniture bodies 2 or 2' to fix one of the sliding doors 3 in the closed position at a time.

Fig. 4A shows in detail the piece of furniture 1' of fig. 3, in which the rear right sliding door 3 has been moved in the opening direction. The intermediate sliding door 4 is held in the closed intermediate position by a retraction device 6, wherein the retraction device 6 holds the right slide 5 in the closed position via a drive 8, wherein the right slide 5 is coupled to the drive 8 via an additionally mounted activation element 7. The intermediate sliding door 4 can be moved out of the closed position into the open position if a certain force is exceeded in the direction of movement.

The device according to the invention for positioning the two sliding doors 3 and 4 is located on the rear first sliding door 3 and has a stop 9, which stop 9 can be moved against a first end face 37 of the sliding part 5 of the intermediate sliding door 4. Thus, the rear sliding door 3 can be coupled to the front second sliding door 4 by means for positioning in order to move the rear sliding door 3 to an end position, in particular a fully open position, in which the sliding doors 3 and 4 essentially overlap one another.

Fig. 4B shows in detail the piece of furniture 1 of fig. 1 and the piece of furniture 1 'of fig. 2, in which the left sliding door 3 has been moved in the opening direction, the piece of furniture 1 and the piece of furniture 1' also having a device for positioning two sliding doors according to the invention, wherein the stop 9 is moved against the second end face 37 of the other sliding part 5 of the front sliding door 4 and the sliding part 5 is arranged between the stop 9 and the pivotable lever 10, so that the two sliding doors 3 and 4 are coupled to one another by the device for positioning. In this case, the stop 9 and the pivotable lever 10 are hinged to one another to form a structural unit. The left sliding door 3 on the furniture carcass 2' can also be moved by means of the device for positioning the two sliding doors into an end position in which the two sliding doors 3 and 4 substantially overlap each other, in particular into a maximum opening position. Subsequently, the respective other rear sliding door 3 must be in the closed position to avoid a collision, since the two sliding doors 3 lie in one plane.

Fig. 5A to 5D show the sliding doors 3 and 4 in a rear side view, but without the furniture carcass 2, 2 'and the sliding track mounted on the furniture carcass 2 or 2', wherein the opening process of one of the sliding doors 3 or 4 is shown. The opening process of the sliding door 4 is described, wherein the opening process of the left sliding door 3 also occurs when the left sliding door 3 moves relative to the sliding door 4, since only the relative movement of the two sliding doors 3 and 4 with respect to each other is influenced by the means for positioning the two sliding doors 3 and 4.

In fig. 5A, the sliding door 4 is in an opening movement overlapping the fixed sliding door 3, wherein the sliding door 4 is held on two sliding parts 5, which two sliding parts 5 are guided on the track of the sliding rail by means of rollers 12. The first rear sliding door 3 is also held on two sliding parts 13, the sliding parts 13 being guided by rollers 14 on a further rail of the sliding track, wherein the rails are arranged adjacent to one another in different planes on the sliding track. The sliding part 11 is provided as a run-out guard on the slide member 5 to prevent the sliding door 4 from being able to accidentally run out of the slide rail completely.

As shown in fig. 5B, if the front sliding door 4 is moved in the opening direction, the U-shaped slide member 5 is moved in a state where the end surface 37 thereof abuts against the stopper 9 of the device for positioning the sliding door. As a result of the rightward travel movement of the slide part 5, the stop 9 is also moved to the right relative to a housing 15 of the device for positioning a sliding door, which housing is fixed to the sliding door 3, so that the lever 10 pivots, which lever 10 engages behind the rear side of the slide part 5, as viewed in the travel direction, as shown in fig. 5C. Thus, by enclosing the slide part 5 by the stop 9 and the rod 10, a coupling is created between the first sliding door 3 and the second sliding door 4, and the means for positioning the sliding doors can now bring the front sliding door 4 into the maximally open position as shown in fig. 5D. In the maximum open position, the sliding doors 3 and 4 are in a substantially overlapping position, wherein the end faces of the sliding doors 3 and 4 do not necessarily have to be flush-aligned in the travel direction surface, but rather a considerable amount of overlap of the front sides is sufficient to create an opening in the furniture body 2 or 2'.

Furthermore, a device for positioning the sliding doors is used such that the first sliding door 3 can always assume a reproducible distance from the second sliding door 4 by a controlled retracting movement when the two sliding doors 3, 4 are close to each other. In addition, the collision of the two sliding doors is thus effectively prevented. Since the runner 5 is enclosed by the stop 9 and the rod 10 on both end faces 37 in the end position as described above, the impact noise and/or rebound reactions associated therewith are also avoided.

The function of the means for positioning will be explained in more detail on the basis of fig. 6A to 6E, which fig. 6A to 6E again show the opening process of fig. 5A to 5D, but in a sectional view, in which the housing 15 of the means for positioning the sliding door is shown open.

in fig. 6A, the slide part 5 moves together with the front sliding door 4 in the opening direction towards the stop 9 of the device for positioning the sliding door. The device for positioning the sliding door comprises a housing 15, which housing 15 is fixed in an open region above the rail on the rear side of the rear sliding door 3, i.e. does not protrude above the upper side of the sliding door 3, wherein a coupling element 16, which is formed integrally with the stop 9, is guided such that it can move linearly on the housing 15, wherein the stop 9 can also be permanently connected to the coupling element 16. This stop 9 extends beyond the upper side of the sliding door 3, however, it is sufficient to firmly enclose the end face 37 of the slide part 5. When the coupling element 16 is moved linearly along the housing 15, this will actuate the damper with the damper housing 17 and the piston rod 18. In this case, the damper is fixed between a holder on the housing 15 and a holder on the coupling element 16 and can therefore slow down the movement of the coupling element 16 relative to the housing 15 after the sliding part 5 hits the stop 9, which consequently also slows down the travel movement of the front sliding door 4 through the sliding part 5 hitting the stop 9.

furthermore, an energy store 19 in the form of a spring, in particular a tension spring, is shown in the housing 15, which is fastened to one end 21 of the housing 15. The opposite end of the accumulator 19 is held on a driver 20, which driver 20 is movable along a guide path 22 on the housing 15. In fig. 6A, the driver 20 is shown in a locked position, in which the accumulator 19 is tensioned.

As shown in fig. 6B, if the slide part 5 is moved in the opening direction, the slide part 5 strikes with its end face 37 against the stop 9 of the coupling element 16. The stop 9 is moved slightly to the right by the kinetic energy and reaches the position shown in fig. 6C. By moving the coupling element 16, the pivotable lever 10 coupled thereto is pivoted out of the inoperative position in fig. 6B and engages behind the slide part 5, so that the slide part 5 is now held on its end face 37 between the stop 9 and the pivotable lever 10.

After the rod 10 has been applied to the slide part 5 as a result of the linear displacement of the coupling element 16, unlocking of the drive 20, which is moved into the unlocked position by the displacement of the coupling element 16, begins, wherein for this purpose the drive 20 is raised slightly by contact with the entry ramp 24, as shown in fig. 6D. In this position, the drive 20 is released from the locking position and can be moved linearly to the right by the accumulator 19, whereby the coupling element 16 is also moved to the right in fig. 6D relative to the housing 15 and the sliding door 3. Due to the relative movement of the coupling element 16 with respect to the housing 15, the damper is compressed, so that the piston rod 18 moves into the damper housing 17 and slows down the movement of the coupling element 16.

The retraction movement thus initiated proceeds until the coupling element 16 reaches the end of the guide path 22 or the other component stops at a stop, thus reaching the end position. The energy accumulator 19 thus moves the coupling element 16 against the force of the damper and in this case moves the sliding door 4 to an end position corresponding to the maximum opening position of the sliding door 4. Since only the relative movement of the sliding doors 3 and 4 is affected by the use of the means for positioning the sliding doors 3 and 4, it is possible to move only the sliding door 3 in the opening direction and to arrange the front sliding door 4 stationary, however without a difference in the relative movement with respect to each other which results in the movement sequence of fig. 6A to 6E.

If the front sliding door 4 is now moved back in the closing direction from the maximum opening position or end position, the rear sliding door 3 is thus held in the closed position by the self-retracting means fastened to the furniture body 2, 2'. The holding force of the self-retracting device is greater than the force that has to be applied by the accumulator 19 for tensioning the device for positioning the sliding doors 3 and 4 according to the invention. Therefore, the accumulator 19 can be tensioned by pulling on the sliding door 4 without moving the sliding door 3. During the movement of the sliding door 4 in the closing direction, the movement sequence proceeds from fig. 6E to the position shown in fig. 6A, in which the energy store 19 is again switched into the tensioning and locking position.

The locking and unlocking of the driver 20 is again shown in detail in fig. 7A to 7C. Guide paths 22 are formed in the housing 15 in the two halves of the housing 15 (see fig. 8), the guide paths 22 having corner ends 23. The through-pin 26 of the driver 20 is guided in this guide path 22, so that no unilateral forces are generated due to the bilateral guidance. In the locking position, the pin 26 is pressed against the side of the corner end 23 facing the energy store 19 by the force of the tensioned energy store 19, and the removal movement of the pin 26 from the corner end 23 is prevented by a section 35 of the coupling element 16, which section 35 rests from above on the through-pin 26 in a groove of the drive 20, as shown in fig. 7A.

If the coupling element 16 is displaced by the sliding part 5 striking the stop 9, the coupling element 16 is moved to the right from the position shown in fig. 7A, so that the entry ramp 24 strikes from below on the through-pin 26, wherein the entry ramp 24 is arranged below the receptacle 25. Thus, as shown in fig. 7B, the pin 26 can be moved upward into the accommodating portion 25 through the end portion 23. Due to the movement of the pin 26 by means of the entry ramp 24, the drive 20 is unlocked and moved from the end 23 into the linear section of the guide path 22. In this linear section of the guide path 22, the driver 20 can be moved together with the coupling element 16 to an end position by the force of the accumulator 19, as shown in fig. 7C. The guidance in the guide path 22 by means of only one pin 26 also has the advantage that the driver 20 can always be aligned with the end 21 of the energy store 19 during the displacement into the end position and thus transverse forces are substantially avoided, also because of the central arrangement of the pin 22 of the receptacle 27 for extending the longitudinal axis of the energy store 19.

If, during the above-mentioned closing movement, the coupling element 16 is moved out in the closing direction from the end position shown in fig. 7C back to the left, the pin 26 is moved along the guide path 22 correspondingly as a result of the insertion in the receptacle 25 until the corner end 23 is reached, and then, as a result of the contact with the outer arc of the corner end 23, a relative movement takes place between the coupling element 16 and the driver 20, the pin 26 disengaging downwards from the receptacle 25, so that the pin 26 is locked again on the end 23 by the section 35 as shown in fig. 7A.

Fig. 8 shows the device for positioning the two sliding doors 3 and 4 in an exploded view. The device comprises a housing 15 formed by two shell-shaped housing parts, wherein a guide path 22 with a corner end 23 is formed on both housing parts. One pin 26 of the drive 20 is guided in each of the two guide paths 22 and the corner end 23 of the housing 15, wherein it is also possible to provide only one guide path on the housing 15. Tilting is preferably avoided by double-sided guidance of the drive 20. The actuator 20 is provided with a receiving portion 27 for mounting one end of the accumulator 19.

The damper with the damper housing 17 and the piston rod 18 can be inserted into the respective receptacles on the housing 15 and the coupling element 16 and optionally locked. Fluid dampers, in particular hydraulic dampers or pneumatic dampers, can be used as dampers. If a heavy sliding door 3 or 4 is to be decelerated, a plurality of dampers may also be connected in parallel or in series.

A stopper 9 protruding upward from the housing 15 is formed on one side on the coupling element 16. On the opposite side, an entry ramp 24 for unlocking the drive 20 and a receptacle 25 adjacent thereto are formed on the coupling element 16, wherein a section 35 for locking the drive 20 on the corner end 23 is formed adjacent to the receptacle 25.

Furthermore, a pivot 28, in particular in the form of an opening, is formed on the coupling element 16, in which pivot 28 a pin on the pivotable lever 10 engages, so that the pivotable lever 10 is pivotably mounted on the coupling element 16. The lever 10 may be mounted so that it can pivot on the coupling element 16 by curved guide means or other means. An actuation stop 29 is formed on the lever 10, which actuation stop 29 can be moved against a stop 36 on the housing 15 when the stop 9 is moved by the slide 5 from its starting position along the guide path 38. Due to the joint linear movement of the pivoting lever 10 and the coupling element 16, the stop 36 presses against the actuation stop 29 and pivots the lever 10 upwards to enclose the end face 37 of the slide part 5.

Fig. 11A and 11B show a modified rod 10 ', which rod 10' would replace rod 10. To overcome the independent incorrect actuation, i.e. if the retraction movement has taken place and the slide member 5 has not previously been enclosed on the end face as shown in fig. 5C and 5D, a lever 10' may be used. The modified lever 10 ' arranged on the pivot 28 on the coupling element 16 ' is supported on the coupling element 16 ' by means of a further energy store 39, for example in the form of a compression spring (as shown in fig. 11A and 11B) or a torsion spring (as shown in fig. 12A and 12B). The pivoting angle of the lever 10 'caused by the force accumulator 39 is limited, for example, by laterally arranged control pins 40 on the lever 10' on a further control curve 41, which control curve 41 is laterally arranged on the housing 15 ', whereby the pivoting range of the lever 10' is controlled as a function of the displacement travel of the coupling element 16 'relative to the housing 15', as shown in fig. 11C and 11D and/or fig. 12C and 12D. As a result of the linear displacement of the slide part 5 between the coupling element 16 'and the housing 15', the control pin 40 slides along the control curve 41, pressing against the control curve 41 as a result of the energy accumulator 39, wherein the lever 10 'is pivoted from the insertion position into the engagement position, wherein finally the slide part 5 is enclosed at both end faces 37 between the stop 9 and the lever 10', as described above. In this case, it is advantageous if the control curve 41 is not embodied as a slotted guide with a corresponding width of the control pin 40, but has a width such that at each point of the displacement travel the width is sufficiently large to enable the lever 10' to be pivoted against the force of the accumulator 39 into the insertion position, as shown in fig. 11C and 11D and/or fig. 12C and 12D.

The sequence provided without incorrect actuation is illustrated in fig. 13A to 13C, wherein a further embodiment variant of the control curve 41, identified by reference numeral 41 ', is shown in fig. 13A to 13C and 14A to 14C, which does not interact with the control pin 40, but with an entry ramp 42 on the lever 10'. In both embodiment variants described here, the rod 10 'can be rolled over by the runner 5 in the event of an independent incorrect actuation of the rod 10' by means of an entry ramp 42 arranged away from the end face of the stop 9, as shown in fig. 14A to 14C. In this case, the lever 10' can be pivoted against the force of the energy store 39 into the insertion position, i.e. rolled over. When the sliding part 5 strikes against the stop 9, the rod 10 ' is completely rolled over and thus caused to pivot independently by the accumulator 39, back into the position defined by the control surfaces 41, 41 ', with further movement of the coupling element 16 '. After the previously occurring independent incorrect actuation of the lever 10', the slide part 5 is again enclosed on both end faces 37 and thus the incorrect actuation is corrected.

In a further embodiment it is furthermore possible, as shown in fig. 15A to 15C, to pivot the rod 10 "mounted on a shaft 28" arranged transversely to the direction described in the first embodiment (preferably at 90 ° thereto) on the housing 15 "and the coupling element 16", and to provide the guide means in the form of a transversely arranged control curve 41 "to guide the rod 10 linearly along the housing 15" after the rod 10 "has pivoted out when the gliding part 5 hits the stop 9". The corresponding guide means may also be formed by ribs, grooves or other guide means. The end edge of the runner 5 can thus advantageously be enclosed under the end face of the sliding door 3 using the stop 9 "and the rod 10", wherein the user therefore cannot see the device from the outside.

Fig. 9 shows a device for positioning a sliding door during installation. In order to be able to bring the two sliding doors 3, 4 into a predetermined position relative to each other and/or to be positioned in a predetermined manner by means of the device, the device must be mounted precisely on the sliding door 3. For this purpose, the housing 15 can be aligned on one side with the gliding part 13 and on the other side with the mounting aid 31. For this purpose, the housing 15 comprises, as shown by way of example in fig. 10, an opening 30, in which opening 30 a head 32 of a mounting aid 31 engages. The mounting aid 31 is fixed to the end face of the housing 15 and has an upwardly projecting tab 33, on which tab 33 a corner web 34 is formed. The web 34 is placed on the upper side of the sliding door 3, so that an optimal vertical alignment of the housing 15 is achieved. Thus avoiding a tilted position of the housing 15 during the mounting process.

In the exemplary embodiment illustrated, the device for positioning two sliding doors 3 or 4 is fixed on the rear side of the rear sliding door 3, irrespective of whether the piece of furniture 1 has two sliding doors 3 or 4 or three sliding doors according to fig. 2. Of course, the device may also be mounted on the front sliding door 4. Furthermore, the device may also interact with a guide member or a member otherwise mounted on another sliding door instead of the slide member 5.

in the exemplary embodiment shown, the means for positioning the sliding doors 3 and 4 are used to control the opening movement, wherein the housing is fixed to the rear sliding door 3. Other applications are possible in which the housing may be fixed to the front sliding door 4. In the field of furniture, a sliding door is understood to mean a linearly movable closing element, which may also be a foldable sliding door or a room divider, for example.
