Description

The invention relates to a functional unit with at least one door compartment for a slidably held door, which has at least a first door element which is slidably held by a displacement device which is arranged within the door compartment.

To close openings of functional units, such as pieces of furniture, room units, kitchens or sleeping areas, one-piece or multi-part doors, possibly folding sliding doors, are often used, which are moved into a door compartment of the functional unit after the opening has been released in order not to appear disruptive.

The US8336972B2 discloses a piece of furniture with a displacement device that includes a mounting profile that is displaceable within a door compartment and connected to a door that has a door element. The displacement device also includes a holding device in the form of a scissor cross, by means of which the mounting profile is held displaceably in a vertical orientation. The displacement device also includes guide rails along which the mounting profile is slidably mounted by means of drives. The door element connected to the mounting profile can thus be retracted into the door compartment and extended out of the door compartment and rotated against an opening in the piece of furniture.

The US9284761B2 discloses a piece of furniture with a displacement device that includes a mounting profile that is displaceable within a door compartment and connected to a door that has two door elements that are connected to one another by hinges and foldable against one another. The first door element is connected to the mounting profile at the back by stop hinges and to the back of the second door element at the front by door hinges. The second door element is connected at the front to a drive which can be moved along a running rail which has two rail sections which are aligned perpendicular to one another and connected to one another by a curved section, of which a first rail section runs into the door compartment and a second rail section runs along the front of the piece of furniture . With this piece of furniture, the door attached to the mounting profile is unfolded after leaving the door compartment and moved in front of a furniture opening.

For both pieces of furniture, the door element connected to the mounting profile rotates immediately after exiting the door compartment, which is why Mobility and rotation of this door element should be guaranteed. If the first door element is connected to a second door element, the second door element should also be able to move freely after exiting the door compartment so that the folding sliding door can be unfolded and folded again. In order to achieve the required mobility of the door element or elements, they are not rigidly guided within the door compartment, which is why lateral deflections are possible when moving within the door compartment. Rigid guidance of the door element or elements would also cause considerable effort.

In order to prevent the door or door element from hitting the front part of the device during lateral movements, it is preferably provided with a spacer roller, by means of which the door or door element is kept at a distance from the device part when it is moved within the door compartment and preferably also during the pivoting process. When moving within the door compartment, the door element or the door elements can rest against the assigned spacer roller and roll off it without contacting the front part of the device. The spacer rollers prevent the door element or elements from hitting device parts of the displacement device; However, precise guidance or stable holding of the door element or elements is not achieved by means of the spacer rollers, which is why undesirable movements, disruptions in displacement and noise, possibly due to hitting the spacer rollers, can still occur.

Furthermore, in these functional units, a relatively large cross-section of the door compartment must be provided so that the door elements cannot hit a side wall or a partition when entering the door compartment or when exiting the door compartment.

The present invention is therefore based on the object of creating an improved functional unit, in particular a piece of furniture, with at least one door compartment and at least one door with one or more door elements, which can be moved into the door compartment by means of a displacement device.

In particular, a functional unit is to be created in which the door elements are guided precisely within the door compartment and preferably also at least at the beginning of the pivoting process. It should therefore be possible to move the door into a door compartment that has the smallest possible dimensions so that the usable space of the functional unit or piece of furniture can be optimized.

The desired improvements should be able to be achieved with simple and cost-effective measures. It should be possible to easily expand functional units that are already in operation and to provide them with the solution according to the invention.

By means of the displacement device, the door element or the door elements, which can be displaced into the door compartment, should be guided advantageously, so that no disturbances, in particular no unwanted movements and noises, arise when the functional unit is used. The door element or elements should be reliably guided and held, resulting in increased ease of operation and ease of use of the functional unit.

The displacement device should be able to be used with any holding devices, such as scissor crosses, parallelograms or cable guides, by means of which a mounting profile that is connected to the door, kept vertically aligned, can be moved within the door compartment.

The displacement device according to the invention should be able to be used advantageously when the door is operated manually and when operated with drive devices which cause the door to move automatically within the door compartment.

The functional unit should be able to be designed as a piece of furniture or a room unit as required.

This task is solved with a functional unit according to claim 1. Advantageous embodiments of the invention are specified in further claims.

The functional unit comprises a door compartment and a door with at least a first door element, which has a first and a second end face that lie opposite one another, which is connected to a displacement device which is arranged within the door compartment, and which is displaceable into the door compartment and can be pivoted outside the door compartment in order to cover an opening of the functional unit, the displacement device being a mounting profile which, on the one hand, is connected to the first end face of the first door element by stop hinges and, on the other hand, is vertically aligned by a holding device between an entrance opening and a rear side of the door compartment along a running axis is held displaceably, and includes at least one spacer device with a device body, which is located at the entrance opening of the door compartment is arranged and which comprises a first spacer roller on which the first door element can roll during a displacement without contacting the device body of the spacer device.

According to the invention, it is provided that the first door element is connected to a first door magnet part on a side facing the distance holding device, and that the distance holding device is connected to a first device magnet part on a side facing the first door magnet part, which interacts magnetically with the first door magnet part in such a way that first door element is pulled against the spacer as soon as the first door magnet part and the first device magnet part, at least one of which is a permanent magnet, lie opposite one another.

The door magnet part or parts and the corresponding device magnet part or parts are therefore designed to be ferromagnetic or permanent magnetic in such a way that they magnetically attract each other. The device magnet part or the device magnet parts are preferably designed to be permanently magnetic, while the door magnet part or the door magnet parts are designed to be ferromagnetic. The device magnet part or the device magnet parts can also be designed to be ferromagnetic while the door magnet part or the door magnet parts are designed to be permanently magnetic. Furthermore, both the device magnet part or the device magnet parts and the door magnet part or the door magnet parts can be designed to be permanently magnetic.

The door magnet part or parts and the corresponding device magnet part or parts are preferably arranged at least approximately at the same height. The door magnet parts are preferably ferromagnetic plates, which are preferably guided past the device magnet part or parts at the same height when the door element or elements are displaced. The door magnet part or parts and the corresponding device magnet part or parts are therefore preferably arranged in such a way that an optimal magnetic coupling results.

The spacer roller or the spacer rollers are preferably arranged at the height of the door magnet part or parts, so that the spacer roller or the spacer rollers are on the associated Door magnet part or a cover lying on it can unroll. This has the advantage that ideal running surfaces for the spacer roller can be formed by means of the door magnet part or parts or their covers and the inside of the door element can therefore have any surface finish.

In all embodiments, the device magnet part is set back relative to the associated spacer roller, so that only the spacer roller, but not the device magnet part, can touch the facing inside of the door element. Spacer rollers made of plastic are preferably used.

The spacer rollers are preferably held by a roller holder which can be adjusted as required. Preferably, the adjustable roller holder is connected to a buffer element, so that with the adjustment of the buffer element, which, for example, forms the end stop for the mounting profile or a guide drive connected to it, the necessary adjustment of the associated spacer roller takes place at the same time.

The device magnet parts are preferably plate-shaped, pill-shaped, tablet-shaped, cylindrical and connected to the device body of the associated spacer device and preferably sunk into a recess in the device body.

The door magnet parts can also be pill-shaped, tablet-shaped, or cylindrical. However, the door magnet parts are preferably designed as plates whose longitudinal axis extends parallel to the direction of displacement of the mounting profile. The door magnet parts are preferably designed as ferromagnetic plates, for example steel plates. The door magnet parts can also be plastic elements or plastic strips in which ferromagnetic or permanent magnetic material, for example steel chips, are enclosed.

The first door element is therefore pulled against the spacer device and thus against the first spacer roller by interaction between the first door magnet part and the first device magnet part, at least in a region in which it is displaceable within the door compartment. The first door element is therefore pushed away from the body of the spacer device by the spacer roller and is simultaneously pulled against the spacer roller by the force of the device magnet part. The first door element therefore remains attached to the door when it is at a standstill The spacer roller is always in a specific position, which is why automatic movements of the first door element and corresponding disturbances, such as impact noises, are excluded. In particular, after fully retracting into the door compartment, the end face of the door element that is remote from the mounting profile and is not directly connected and held to the mounting profile rests against the spacer roller and cannot carry out any unwanted pivoting movements. When the first door element is moved within the door compartment, the first door element follows a travel path determined by the spacer roller and is therefore precisely inserted into the door compartment and extended out of the door compartment. Contacting a side wall or a partition wall through the door element or the door elements can therefore be excluded.

Due to the precise guidance of the door element or the door elements of the door, the functional unit or the piece of furniture can be provided with a door compartment or a first and a second door compartment that have minimal dimensions.

The inventive guidance of the door elements by magnetic coupling is also particularly advantageous because the coupling of the door elements to the spacer device and in particular the decoupling of the door elements from the spacer device is always optimal and safe without the need for mechanical guidance.

In a preferred embodiment of the functional unit it is provided that the first door element is connected on the second end face by door hinges to a facing first end face of a second door element, which can be inserted into the door compartment in parallel alignment with the first door element in such a way that the at least one Spacer device, which has a second spacer roller facing the second door element, is enclosed between the first and second door elements. It is provided that the second door element is connected to a second door magnet part on a side facing the distance holding device, and that the distance holding device is connected to a second device magnet part on a side facing the second door magnet part, which interacts magnetically with the second door magnet part and this against Distance holding device pulls.

When using a folding sliding door, the first and second door elements are preferably provided with door magnet parts that are magnetic with device magnet parts of the spacer device cooperate. This ensures that both door elements are held precisely and guided precisely. The mobility of the two door elements on the end faces connected to each other by the door hinges is thus eliminated, which is why unwanted movements and uncontrolled progression are avoided.

In a further preferred embodiment it is provided that an upper spacer device is arranged on the top of the door compartment, and that the first door element is connected to an upper first door magnet part on the side facing the upper spacer device, and that the upper spacer device is on one of the upper first The side facing the door magnet part is connected to at least one upper first device magnet part, which magnetically cooperates with the upper first door magnet part; and that a lower spacer device is arranged on the underside of the door compartment, and that the first door element is connected to a lower first door magnet part on the side facing the lower spacer device, and that the lower spacer device is connected to at least one lower one on a side facing the lower first door magnet part first device magnet part is connected, which interacts magnetically with the lower first door magnet part.

The first door element is therefore held and guided precisely on the top and bottom. If the first door element is connected to a second door element, the second door element is preferably also held precisely on the top and bottom by means of the measures according to the invention.

It is preferably provided that the second door element is connected to an upper second door magnet part on the side facing the upper spacer device, and that the upper spacer device is connected to at least one upper second device magnet part on a side facing the upper second door magnet part, which is connected to the upper second device magnet part Door magnet part interacts magnetically; and that the second door element is connected to a lower second door magnet part on the side facing the lower spacer device, and that the lower spacer device is connected to at least one lower second device magnet part on a side facing the lower first door magnet part, which interacts magnetically with the lower second door magnet part .

As has already been described, at least one of the door magnet parts and corresponding device magnet parts is designed to be permanently magnetic.

In particularly preferred embodiments, it is provided that the mounting profile is connected at an upper end piece to an upper guide drive, which is slidably mounted on an upper guide rail, from which the upper spacer device is held at the front, and / or that the mounting profile is connected to a lower end piece lower guide drive is connected, which is slidably mounted on a lower guide rail, from which the lower spacer is held on the front.

The mounting profile is kept stable by means of the guide drives and the guide rails. The load of the door connected to the mounting profile is absorbed. The holding device, e.g. a scissor cross, a parallelogram or a cable pull device, therefore only absorbs acting torques. At the same time, the spacer devices can be easily mounted on the end faces of the guide rails facing the exit of the door compartment. The spacer rollers ensure that the held door elements cannot collide with the device body of the spacer devices or with the guide rails or carry out further undesired movements.

The first door magnet parts or the first and second door magnet parts preferably extend in a plate-like manner parallel to the running axis of the mounting profile, so that the magnetic coupling between the door magnet parts and the corresponding device magnet parts when the door element or the door elements are displaced is preferably over the entire range of displacement or over one critical area within the door compartment remains unchanged.

The first door magnet parts or the first and second door magnet parts are preferably arranged and fastened in a door recess of the first door element or the first and second door elements, preferably screwed, clamped, glued or cast.

Furthermore, the door magnet parts are preferably covered with covers so that they are not visually noticeable. The door magnet parts and the covers are preferably completely recessed into the door elements, so that the door elements have a flat surface over the entire area.

The door magnet parts or their covers preferably form the running surfaces for the spacer rollers. This ensures that the spacer rollers can roll on ideal running surfaces without wear and noise.

The first door magnet parts connected to the first door element preferably extend completely or partially over the width of the first door element directly or at a small distance from the end face of the first door element remote from the mounting profile.

The second door magnet parts connected to the second door element preferably extend completely or partially over the width of the second door element directly or at a small distance from the end face of the second door element connected to the first door element.

The device body of the spacer devices is preferably made of metal or plastic and is connected to the associated first device magnet part or the first and second device magnet parts in a form-fitting or non-positive manner, if necessary by magnetic force. The device body preferably has shaped elements by means of which the device magnet parts are held in a form-fitting manner. If the device body is made of ferromagnetic material and has receiving openings for the device magnet parts, the device magnet parts are automatically held in the receiving openings. The device magnet parts can also be screwed to the device body. For example, the device magnet parts have a hole through which a connecting screw is passed and screwed into a threaded hole in the device body.

The device magnet parts are preferably plate-shaped, for example rectangular or round, or cylindrical, or pill-shaped and aligned parallel to the door magnet parts, so that an optimal magnetic interaction is achieved.

The door magnet parts or device magnet parts designed as permanent magnets are preferably rare earth magnets, which essentially consist, for example, of ferrous metals (iron and/or cobalt and/or nickel) and rare earth metals (in particular neodymium, samarium, praseodymium, dysprosium, terbium, or gadolinium). .

The spacer devices preferably have different functions and elements. The spacer devices preferably include adjustable or non-adjustable coupling elements for coupling the holding device and/or stop elements or damper elements which can interact with the guide drives. Preferably, the adjustable buffer devices are mechanically coupled to the spacer rollers.

The spacer devices used can be identical or partially identical, so that they can be manufactured cost-effectively.

The functional unit can be a piece of furniture, for example a cupboard, or a room unit, such as a kitchen, a chamber or a bedroom, which is closed by at least one one-part or multi-part door, which can be parked in a door compartment.

Fig. 1 shows a functional unit according to the invention or a piece of furniture 1 in the design of a cupboard, in which a door compartment 18 is integrated on both sides. The piece of furniture 1 includes side walls 1A, a top panel 1B, a bottom panel 1C and partition walls 1D, each of which delimits a door compartment 18 with an associated side wall 1A. A displacement device 10 according to the invention with a mounting profile 14 is arranged in each door compartment 18, which is activated by manual operation or by means of a drive device (see Fig. 3 , drive device 2) can be moved automatically within the door compartment 18. From the mounting profiles 14 of Doors 11 are held by sliding devices 10 and are moved into or out of the associated door compartment 18 when the mounting profile 14 is moved. When the door 11 exits the door compartment 18 in question, the mounting profile 14 is moved along a running axis x from the back 181 of the door compartment 18 to an entrance opening 180 of the door compartment 18.

A folding sliding door 11 is held in the first door compartment 18 and has a first and a second door element 111, 112, which are articulated to one another and can be folded against one another. However, the door 11 held in the second door compartment 18 by the mounting profile 14 there within the second door compartment 10 only has one door element 111. The first door element 111 has an inside 1111 and an outside 1112. The second door element 112 has an inside 1121 and an outside 1122 (see Fig. 4b ).

In Fig. 1 the folding sliding door 11 is completely pulled out of the first door compartment 10 and fully unfolded, so that the door elements 111, 112 are aligned in one plane and only their outsides 1112, 1122 are visible. The door elements 111, 112 of the folding sliding door 11 and the door element 111 of the one-piece door 11 are the same size, which is why two thirds of the cabinet opening 100 are covered by the folding sliding door 11 shown in the closed position.

The end face 1115 of the first door element 111 of the folding sliding door 11, which trails when the sliding door 11 is extended, is connected by stop hinges 131 to the mounting profile 14, symbolically shown by a dash-dotted line.

The leading end face 1116 of the first door element 111 is connected by door hinges 132 to the trailing end face 1125 of the second door element 112, the leading end face of which is connected at the top to a front drive 5F. The front drive 5F is guided in a connecting rail 17, which is connected on both sides by curved sections to upper guide rails 15, which run into the door compartments 18. When entering the door compartment 18 and when traveling along the connecting rail 17, the front drive 5F moves forward within an assigned path, with the change of direction taking place within the curve section.

Functional units 1 according to the invention have at least one spacer device 7, 8. Fig. 1 shows schematically that in this preferred embodiment of the functional unit 1 each of the Displacement devices 10 have an upper spacer 7 and a lower spacer 8, which allow the doors 11 or the door elements 111, 112 to be guided and held precisely.

Fig. 2 shows the one in the first door compartment 18 of the functional unit 1 of Fig. 1 arranged displacement device 10 with the folding sliding door 11, the door elements 111, 112 of which are shown in section to show the spacer devices 7 and 8. The door elements 111, 112, which are connected to one another by door hinges 132 shown schematically, are aligned parallel to one another and can be inserted into the door compartment 18 in this orientation.

The mounting profile 14 is connected to the first door element 111 by stop hinges 131 and is held displaceably in a vertical orientation by a holding device 4 (shown symbolically by dash-dotted lines). The holding device 4 can be designed in any way and, for example, in the form of a scissor cross, a parallelogram or preferably in a device with retaining ropes according to Fig. 3 be realized.

The mounting profile 14 is connected at the upper end to an upper guide drive 5, which is guided in an upper guide rail 15, and at the lower end to a lower guide drive 6, which is guided in a lower guide rail 16. The upper guide drive 5 includes support rollers 591 and guide rollers 592 and, in addition to the guide functions, also has a carrying function. The lower guide drive 6 includes guide rollers 692, which are guided in the lower guide rail 16 (see Fig. 3 ).

The upper guide drive 5 and the lower guide drive 6 lie immediately in front of the entrance opening 180 of the door compartment 18. The drive body 51 of the upper guide drive 5 rests on a buffer device or damper device 3 which is mounted in the upper guide rail 15.

The upper guide rail 15 holds an upper spacer device 7 on the front and the lower guide rail 16 holds a lower spacer device 8 on the front, each of which has a device body 71, 81. Fig. 2 shows that the spacer devices 7, 8 are enclosed between the two door elements 111, 112 which are aligned parallel to one another.

On the side facing the first door element 111, the upper and lower spacer devices 7, 8 each have at least one first Spacer roller 791, 891 and at least one first device magnet part 771, 871 each. On the side facing the second door element 112, the upper and lower spacer devices 7, 8 each have at least one second spacer roller 792, 892 and at least one second device magnet part 772, 872 each.

The first spacer rollers 791, 891 keep the first door element 111 at a distance and can roll on the inside 1111. The second spacer rollers 792, 892 keep the second door element 112 at a distance and can roll on its inside 1121. The two door elements 111, 112 can therefore not abut inwards against the device bodies 71, 81 of the spacer devices 7, 8 or against the guide rails 15, 16.

The first device magnet parts 771, 871 cooperate with first door magnet parts 751, 851 which are connected to the first door element 111 (see Fig. 5 ). The second device magnet parts 772, 872 cooperate with second door magnet parts 752, 852 which are connected to the second door element 112. The first and second device magnet parts 771, 871; 772, 872 the first and second door magnet parts 751, 851; 752, 852 interact magnetically and exert forces on each other, through which the two door elements 111, 112 are pulled against the spacer devices 7, 8. The first and/or the second spacer rollers 791, 891; 792, 892 are therefore always in contact with the insides 1111, 1121 of the first and/or second door element 111, 112 and preferably run there on the door magnet part 751, 851; 752, 852 or one on the door magnet part 751, 851; 752, 852 provided cover 76, 86, which are preferably designed as treads. As mentioned, at least one of the corresponding device magnet parts 771, 871; 772, 872 and the door magnet parts 751, 851; 752, 852 are permanently magnetic, so that a permanent magnetic part interacts with a ferromagnetic part. In preferred embodiments, the device magnet parts 771, 871; 772, 872 and the door magnet parts 751, 851; 752, 852 be designed to be permanent magnetic.

When moving into the door compartment 18 or out of the door compartment 18, the two door elements 111, 112 are guided and held without play or largely without play by means of the two spacer devices 7, 8. In particular, even after the two door elements 111, 112 have entered the door compartment 18, their end faces 1116, 1125, which are connected to one another by the door hinges 132, are covered by the Spacer devices 7, 8 are kept stable. The door elements 111, 112 are therefore kept stable when driving and also when stationary and can neither strike inwards against the guide rails 15, 16 nor outwards against a side wall 1A or a partition 1D (see Fig. 1 ).

The displacement device 10 can be used to hold a one-piece or multi-piece door 11. Regarding Fig. 2 the use of the displacement device 10 in combination with a door with 2 door elements 111, 112 was described. The spacer devices 7, 8 according to the invention, however, can also only be used to guide a door element 111 of a one-piece door 11 or the first door element 111 of a multi-part door 11. Fig. 5 shows part of a displacement device 10, which is intended for guiding only one door element 111.

Fig. 3 shows the displacement device 10 from Fig. 2 with a preferred holding device 4 and an optionally provided drive device 2 from the other side.

The holding device 4 comprises a first front cable connection device 84, a first lower roller unit 431, which is arranged at the lower end of the mounting profile 14, a first upper roller unit 411, which is arranged at the upper end of the mounting profile 14, and a first rear cable connection device 44, which is arranged at the rear end of the upper guide rail 15, as well as a first tether 421, which is connected with a first end piece to the first front cable connection device 84, guided counterclockwise around the first lower roller unit 431 and clockwise around the first upper roller unit 411 and with a second end piece is connected to the first rear cable connection device 44.

Furthermore, the holding device 4 comprises a second front cable connection device 74, a second upper roller unit 412, which is arranged at the upper end of the mounting profile 14, a second lower roller unit 432, which is arranged at the lower end of the mounting profile 14, and a second rear cable connection device 45, which is arranged at the rear end of the lower guide rail 16, and a second tether 422, which is connected with a first end piece to the second front cable connection device 74, clockwise around the second upper roller unit 412 and counterclockwise around the second lower one Roller unit 432 is guided and connected with a second end piece to the second rear cable connection device 45.

The preferably adjustable first front cable connection device 84, by means of which the first pull cable 421 can be tensioned in order to vertically align the mounting profile 14, is integrated into the lower spacer device 8. The second front cable connection device 74 is integrated into the upper spacer device 7. The two rear cable connection devices 44, 45 preferably each have an input roller via which the relevant tether 421, 422 can be inserted into a housing. Preferably, a tension spring is provided in the second rear cable connection device 45, via which a constant tensile force can be transmitted to the second tether 422.

In the holding device 4 according to the invention, one of the holding ropes 421, 422, in this embodiment the second holding rope 422, is preferably always held elastically. After installation, however, the first tether 421 is held inelastically or firmly by the first front cable connection device 84 and the first rear cable connection device 44. The first front cable connection device 84 is adjustable in order to tighten the first tether 421 and to align the mounting profile 14 vertically.

Furthermore, the displacement device 10 optionally includes a drive device 2, by means of which the door 11 can be automatically ejected from the door compartment 18. The drive device 2 shown as an example and preferably used comprises a drive unit 21 with a drive element and a pulley connected thereto, onto which a pull rope 22 is wound. The drive element is, for example, a spiral spring or a helical spring, which is tensioned or relaxed when the pulley rotates. The pull rope 22 can therefore be pulled from the pulley by applying force and is automatically wound back onto the rotating pulley.

The traction cable 22 is guided via a first deflection roller 23, which is rotatably mounted on a deflection unit 230, and a second deflection roller 24 to a traction cable connection 72, which is arranged on the upper spacer device 7. The deflection unit 230 can be moved along the mounting profile 14 and optionally fixed. By moving the deflection unit 230, a desired tension can be impressed into the pull rope 22.

In Fig. 3 The mounting profile 14 was moved almost to the back 181 of the door compartment 18, which is why the pull cable 22 was pulled out further and the drive element was tensioned. As soon as the pull rope 22 is released again, the pulley is turned back by the tensioned drive element.

By connecting the drive device 2 with the mounting profile 14 or the guide drive 5, there is no need to mount the drive device 2 on a rear wall, a partition 1D or a side wall 1A of the functional unit 1. It is particularly advantageous that the displacement device 10 is connected to the holding device 4 and the drive device 2 can be installed in differently sized door compartments 18 without modification. Only the lengths of the retaining ropes 421, 422 and the pull rope 22 need to be adjusted accordingly.

It is also shown that the spacer devices 7, 8 are provided with rotatable locking levers 73, 83, by means of which the mounting profile 14 moved to the opening 180 of the door compartment 18 can be locked in order to carry out maintenance work or make adjustments.

Fig. 4a shows the upper spacer 7 from Fig. 2 with the device magnet parts 771, 772 detached from the device body 71 and a section through the two door elements 111, 112, which shows the door magnet parts 751, 752 sunk into the door elements 111, 112 and the covers 76 lying thereon in a sectional view. The device body 71 of the spacer device 7 includes a mounting beam 711 on the top, which was inserted into a mounting channel of the upper guide rail 15 and locked by locking screws 712. The upper guide rail 15 is shown symbolically with dash-dotted lines.

If the upper and lower guide rails 15, 16 have the same or at least functionally identical receiving channel, for example when using a scissor cross as a holding device 4, the upper spacer device 7 can be turned by 180 ° and used as a lower spacer device 8. The spacer device 7 can also be connected to a device magnet part 771 on only one side if only one door element 111 needs to be moved into the door compartment 118.

In this preferred embodiment, the device body 71 has threaded holes on both sides into which connecting screws 78 can be screwed in order to mount the first device magnet part 771 on one side and the second device magnet part 772 on the other side of the device body 71. Preferably an elastic one Element 781 is provided between the connecting screws 78 and the device magnet parts 771, 772, which elastically transmits the expressive force of the connecting screws 78 to the device magnet parts 771, 772. However, the device magnet parts 771, 772 can also be connected to the device body 71 in a non-positive or positive manner in another way. For example, the device magnet parts 771, 772 can be inserted into recesses in the device body 71, for example glued and/or cast or only held magnetically. If the device body 71 is made of a ferromagnetic material, the device magnet parts 771, 772 are automatically held in the recesses of the device body 71.

The first plate-shaped door magnet part 751 is arranged within a door recess 1110 on the inside 1111 of the first door element 111 and fastened by means of a mounting screw 7511. A cover or cap 76 is inserted into the door recess 1110, the outside of which lies in a plane with the inside 1111 of the first door element 111. The second plate-shaped door magnet part 752 is arranged within a door recess 1120 on the inside 1121 of the second door element 112 and fastened by means of a mounting screw 7521. A cover or cap 76 is inserted into the door recess 1120, the outside of which lies in a plane with the inside 1121 of the second door element 112.

The cover 76 can be made of metal, plastic or wood, for example. Alternatively, the cover 76, for example a film or a plate, can cover the entire inside 1111, 1121 of the door elements 111, 112. In preferred embodiments, the cover 76 therefore forms a coating on the door elements 111, 112.

Fig. 4b shows the upper spacer 7 from Fig. 4a after assembly of the device magnet parts 771, 772. Instead of the upper guide rail 15, the upper guide drive 5 with the support rollers 591 and the guide rollers 592 is shown in this illustration. It can be seen that the door elements 111, 112 shown in sectional view are, on the one hand, kept at a distance from the device body 71 by the spacer rollers 791, 792 and are simultaneously pulled against the spacer rollers 791, 792 by the device magnet parts 771, 772. Both when the door 11 is moved and when it is at a standstill, it is held precisely.

Fig. 5 shows the upper and lower spacer devices 7, 8 of Fig. 2 in a preferred embodiment for guiding a door 11 with only one separating element 111, from which a center piece has been cut out. The spacer devices 7, 8 are consequently provided with a spacer roller 791, 891 and a device magnet part 771, 871 on only one side. The upper guide rail 15 and the lower guide rail 16, which hold the upper and lower spacer devices 7, 8 on the front, are shown shortened. On the inside 1111 of the door element 111, door recesses 1110 are provided, which extend almost over the entire width of the door element 111. A part of the plate-shaped upper door magnet part 751 was cut away to show the door recess 1110. The plate-shaped door magnet parts 751, 752 have holes 7510, 8510 into which mounting screws 7511 are inserted. The covers 76, 86 extend over the entire length of the door recesses 1110.

Fig. 6a shows the upper spacer 7 from Fig. 5 which is held by the upper guide rail 15. The upper guide rail 15 has a mounting channel 150 on the underside, into which a mounting beam 711 connected to the device body 71 of the upper spacer device 7 is inserted. The mounting beam 711 used is locked or clamped using locking screws 712. Above the mounting channel 150, the upper guide rail 15 has a cross section within which the upper guide drive 5 can be moved up to a buffer device or damper device 3.

The device magnet part 771, which is set back relative to the spacer roller 791, is plate-shaped in this embodiment and is preferably held in a recess 710 of the device body 71 and fixed with a connecting screw 78. The device magnet parts 771, 772; 871, 872, on the other hand, can have any shape and, for example, be cylindrical, pill-shaped, tablet-shaped, plate-shaped and have a round, rectangular, square or polygonal cross section. The contactless interaction of the door magnet parts 751, 752; 851, 852 and the device magnet parts 771, 772; 871, 872 allows the latter to be connected to the device body 71, 81 at a location where no further function of the spacer device 7, 8 is impaired.

The spacer roller 791 is rotatably mounted in a roller holder 715 by means of a bearing shaft 790. The roll holder 715 is preferred held firmly or displaceably in a storage chamber 716 of the device body 71 and is fixed by means of a mounting screw or adjusting screw 713. Preferably, the roller holder 715 is slidably mounted and can be selectively positioned using the adjusting screw 713.

It should be noted that the spacer roller 791 projects beyond the device body 71 in this preferred embodiment not only on the side of the associated device magnet part 78 but also at the front. The door element is therefore not only guided during the axial displacement within the door compartment 18 but also during the pivoting movement at the exit of the door compartment 18 and kept at a distance from the device body 71.

Fig. 6b shows the lower spacer 8 from Fig. 5 which is held by the lower guide rail 16. The lower guide rail 16 also has a mounting channel 160, in which a mounting beam 811 connected to the device body 81 of the lower spacer device 8 is held. The lower roller holder 815 is also slidably mounted and includes a buffer body 8153, which holds a buffer element 8154 and which is guided through an opening in the device body 81.

The lower and upper spacer devices 7, 8 are therefore fundamentally interchangeable. Furthermore, the spacer devices 7, 8 can advantageously have further functional elements, such as preferably adjustable buffer devices, damping devices, stop devices, locking levers 83, cable connection devices 84.

Fig. 7 shows part of the displacement device 10 from Fig. 2 with the upper spacer device 7, which in this preferred embodiment has two spacer rollers 791, 792. The first spacer roller 791 is held by a roller holder 715, which is slidably mounted within a bearing chamber 716 of the device body 71 and is optionally displaceable by means of an adjusting screw 713. The guide drive 5, which is guided within the upper guide rail 15, has advanced with the drive body 51 to the damping device 3.

Fig. 8 shows the upper spacer 7 from Fig. 7 in exploded view. The roller holder 715 includes guide ribs 7151 on the bottom and top, which are guided in corresponding guide tracks 718 of the storage chamber 716. The roller holder 715 is also preferably connected in one piece to a buffer piston 7153, A buffer element 7154 is held on the front side. The spacer roller 791 and the buffer element 7154 are therefore preferably firmly coupled to one another, so that when the end stop of the upper guide drive 5 is adjusted, the first spacer roller 791 is optimally positioned at the same time and does not have to be positioned separately. In addition, the roller holder 715 includes a holding flange 7152, by means of which the head of the adjusting screw 713 is held rotatably but not axially displaceable within a screw chamber. Furthermore, the roller holder 715 has a tool opening 7150 through which a screwdriver can be inserted into the screw chamber in order to rotate the adjusting screw 713.

The device body 71 has a storage chamber 716 into which the roller holder 715 can be inserted. A transfer opening 717 is provided on the rear wall of the storage chamber 716, through which the buffer piston 7153 with the buffer element 7154 is guided. A threaded hole 719 is also provided on the rear wall of the storage chamber 716, into which the adjusting screw 713 is screwed. By rotating the adjusting screw 713, the roller holder 715 with the first spacer roller 791 and the buffer element 7154 can therefore be selectively displaced relative to the device body 71.
