Description

[0001] The invention relates to a functional unit with at least one door compartment for a sliding door, which has at least one first door element that is slidably held by a sliding device arranged within the door compartment.

[0002] To close off openings of functional units, such as pieces of furniture, room units, kitchens or sleeping areas, one-piece or multi-piece 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, so as not to be obtrusive.

[0003] US patent 8336972B2 discloses a piece of furniture with a sliding device comprising a mounting profile that is slidably positioned within a door compartment and connected to a door having a door element. The sliding device also includes a holding device in the form of a scissor mechanism, by means of which the mounting profile is held slidably in a vertical orientation. The sliding device further comprises guide rails along which the mounting profile is slidably mounted by means of carriages. The door element connected to the mounting profile can thus be moved into and out of the door compartment and rotated against an opening of the piece of furniture.

[0004] WO2020245166A1 discloses a holding device having a structure with parallelograms.

[0005] US9284761B2 discloses a piece of furniture with a sliding device comprising a mounting profile that is slidable within a door compartment and connected to a door having two hinged door elements that can be folded relative to each other. The first door element is connected at the rear to the mounting profile by stop hinges and at the front to the rear of the second door element by door hinges. The second door element is connected at the front to a track that is slidable along a rail. The track has two perpendicular sections connected by a curved section, the first of which extends into the door compartment and the second of which extends along the front of the furniture. In this piece of furniture, the door, hinged to the mounting profile, is unfolded after exiting the door compartment and moved in front of a furniture opening.

[0006] In both pieces of furniture, the door element connected to the mounting profile rotates immediately after being extended from the door pocket. Therefore, the mobility and rotation of this door element must be ensured. If the first door element is connected to a second door element, the second door element should also be able to move freely after being extended from the door pocket, allowing the folding sliding door to unfold and fold closed again. To achieve the necessary mobility of the door element(s), they are not rigidly guided within the door pocket, which allows for lateral deflection during movement. Furthermore, rigid guidance of the door element(s) would significantly increase the complexity of the design and construction.

[0007] To prevent the door or door element from striking the front-facing device part during lateral movements, the device part is preferably equipped with a spacer roller. This roller keeps the door or door element at a distance from the device part during movement within the door compartment and preferably also during pivoting. When moving within the door compartment, the door element(s) can rest against the associated spacer roller and roll along it without contacting the front-facing device part.The spacer rollers thus prevent the door element(s) from striking the device parts of the sliding mechanism; however, precise guidance or stable holding of the door element(s) is not achieved by means of the spacer rollers, which is why unwanted movements, disturbances in the sliding and noises, possibly due to striking the spacer rollers, can still occur.

[0008] Furthermore, these functional units require a relatively large cross-section of the door compartment so that the door elements cannot hit a side wall or partition wall when entering or exiting the door compartment.

[0009] A piece of furniture in which a door is guided by spacer rollers is also known from CN108071288A.

[0010] The present invention is therefore based on the objective 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 sliding device.

[0011] In particular, a functional unit must be created in which the door elements are precisely guided within the door frame and preferably also at least at the beginning of the swinging motion. This should make it possible to slide the door into a door frame with the smallest possible dimensions, thus optimizing the usable space of the functional unit or piece of furniture.

[0012] The desired improvements should be achievable with simple and cost-effective measures. It should be possible to easily expand existing functional units and equip them with the solution according to the invention.

[0013] The sliding device is intended to guide the door element(s) that can be slid into the door compartment advantageously, so that no disturbances, in particular no unwanted movements or noises, occur during the use of the functional unit. The door element(s) should be reliably guided and held, resulting in increased ease of operation and user comfort of the functional unit.

[0014] The sliding device according to the invention should be usable with any holding devices, such as scissor crosses, parallelograms or cable guides, by means of which a mounting profile connected to the door can be held vertically aligned and moved within a door compartment.

[0015] The sliding device according to the invention should be advantageously usable both when the door is operated manually and when operated with drive devices that cause the door to move automatically within the door compartment.

[0016] The functional unit should be able to be designed as a piece of furniture or a room unit, as needed.

[0017] This problem is solved with a functional unit according to claim 1. Advantageous embodiments of the invention are specified in further claims.

[0018] The functional unit comprises a door compartment and a door with at least one first door element having a rear and a front end face opposite each other, connected to a sliding device arranged inside the door compartment, and being slidable into the door compartment and pivotable outside the door compartment to cover an opening of the functional unit, wherein the sliding device comprises a mounting profile which is connected on the one hand to the rear end face of the first door element by stop hinges and on the other hand is held slidably by a retaining device in a vertical orientation between an entrance opening and a rear of the door compartment along a running axis, and at least one spacer device with a device body which is arranged at the entrance opening of the door compartment and which comprises a first spacer roller.where the first door element can roll during a movement without contacting the device body of the spacer device.

[0019] According to the invention, the first door element is connected on a side facing the spacer device to a first door magnet part, and the spacer device is connected on a side facing the first door magnet part to a first device magnet part, which magnetically interacts with the first door magnet part in such a way that the first door element is pulled against the spacer device as soon as the first door magnet part and the first device magnet part, at least one of which is a permanent magnet, are opposite each other.

[0020] The door magnet part(s) and the corresponding device magnet part(s) are therefore designed to be ferromagnetic or permanent magnets such that they attract each other magnetically. The device magnet part(s) are preferably permanent magnets, while the door magnet part(s) are ferromagnetic. However, the device magnet part(s) can also be ferromagnetic while the door magnet part(s) are permanent magnets. Furthermore, both the device magnet part(s) and the door magnet part(s) can be permanent magnets.

[0021] The door magnet(s) and the corresponding device magnet(s) are preferably arranged at least approximately at the same height. The door magnets are preferably ferromagnetic plates that, when the door element(s) are moved, preferably pass the device magnet(s) at the same height. The door magnet(s) and the corresponding device magnet(s) are therefore preferably arranged such that optimal magnetic coupling results.

[0022] The spacer roller(s) are preferably arranged at the same level as the door magnet(s) so that they can roll on the associated door magnet or a cover or coating placed upon it. This has the advantage that the door magnet(s) or their covers provide ideal running surfaces for the spacer roller(s). The inside of the door element can therefore have any desired surface finish. Additionally, the cover or coating protects the magnets against external chemical or mechanical influences.

[0023] In all embodiments, the device magnet part is set back relative to the associated spacer roller, so that only the spacer roller, and not the device magnet part, can touch the facing inner side of the door element. Preferably, spacer rollers made of plastic are used.

[0024] The spacer rollers are preferably held by a roller bracket that is adjustable as needed. Preferably, the adjustable roller bracket is connected to a buffer element, so that adjusting the buffer element, which for example forms the end stop for the mounting profile or an associated guide carriage, simultaneously adjusts the corresponding spacer roller.

[0025] The device magnet components are preferably plate-shaped, pill-shaped, tablet-shaped, or cylindrical and are connected to the device body of the associated spacer device and preferably recessed into a recess in the device body. The device magnet components can also have several magnetic elements, which are preferably plate-shaped, pill-shaped, tablet-shaped, or cylindrical.

[0026] The door magnet components can also be pill-shaped, tablet-shaped, or cylindrical, or comprise pill-shaped, tablet-shaped, or cylindrical magnetic elements. Preferably, however, the door magnet components are designed as plates whose longitudinal axis extends parallel to the direction of movement of the mounting profile. Preferably, the door magnet components are designed as ferromagnetic plates, for example, steel plates. The door magnet components can also be plastic elements or plastic strips in which ferromagnetic or permanent magnetic material, for example, steel shavings, is enclosed.

[0027] The first door element is therefore, at least in the area where it is movable within the door frame, pulled against the spacer device and thus against the first spacer roller by the interaction between the first door magnet and the first device magnet. The first door element is thus pushed away from the body of the spacer device by the spacer roller and simultaneously pulled against the spacer roller by the force exerted by the device magnet. The first door element therefore remains in a fixed position against the spacer roller when stationary, thus preventing any uncontrolled movement of the first door element and any associated disturbances, such as knocking noises.Particularly after the door element has been fully inserted into the door compartment, the front edge of the door panel furthest from the mounting profile, which is not directly connected to and held by the mounting profile, rests against the spacer roller and cannot perform any unwanted pivoting movements. When the first door element moves within the door compartment, it follows a path determined by the spacer roller and is therefore precisely inserted into and removed from the door compartment. Contact between the door element or the door panels with a side wall or partition is therefore impossible.

[0028] Due to the precise guidance of the door element or door elements of the door, the functional unit or piece of furniture can be provided with a door compartment or a first and a second door compartment, which have minimal dimensions.

[0029] 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 always takes place optimally and safely, without the need for mechanical guidance.

[0030] In a preferred embodiment of the functional unit, the first door element is connected at its front end face by door hinges to a rear end face of a second door element, which can be inserted into the door recess in a parallel orientation to the first door element such 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. The second door element is connected on one side facing the spacer device to a second door magnet part, and the spacer device is connected on the other side facing the second door magnet part to a second device magnet part, which interacts magnetically with the second door magnet part and pulls it against the spacer device.

[0031] When using a folding sliding door, the first and second door panels are preferably equipped with magnetic door components that interact magnetically with the magnetic components of the spacer device. This ensures that both door panels are held and guided precisely. The movement of the two door panels, which are connected at their facing ends by door hinges, is thus eliminated, preventing unwanted movement and uncontrolled operation.

[0032] 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 on the side facing the upper spacer device to an upper first door magnet part, and that the upper spacer device is connected on a side facing the upper first door magnet part to at least one upper first device magnet part which magnetically interacts 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 on the side facing the lower spacer device to a lower first door magnet part, and that the lower spacer device is connected on a side facing the lower first door magnet part to at least one lower first device magnet part which interacts magnetically with the lower first door magnet part.

[0033] The first door element is therefore precisely held and guided at the top and bottom. If the first door element is connected to a second door element, the second door element is preferably also precisely held at the top and bottom by means of the measures according to the invention.

[0034] Preferably, the second door element is connected on the side facing the upper spacer device to an upper second door magnet part, and the upper spacer device is connected on a side facing the upper second door magnet part to at least one upper second device magnet part, which magnetically interacts with the upper second door magnet part; and the second door element is connected on the side facing the lower spacer device to a lower second door magnet part, and the lower spacer device is connected on a side facing the lower first door magnet part to at least one lower second device magnet part, which magnetically interacts with the lower second door magnet part.

[0035] As already described, at least one of the door magnet parts and corresponding device magnet parts is permanently magnetic.

[0036] In particularly preferred embodiments, the mounting profile is connected at an upper end piece to an upper guide carriage which is slidably mounted on an upper guide rail, from which the upper spacer device is held at the front, and / or the mounting profile is connected at a lower end piece to a lower guide carriage which is slidably mounted on a lower guide rail, from which the lower spacer device is held at the front.

[0037] The guide carriages and guide rails hold the mounting profile securely in place. They absorb the load of the door connected to the mounting profile. Therefore, the holding device, such as a scissor mechanism, a parallelogram linkage, or a cable pulley system, only needs to absorb applied torques. Simultaneously, the spacer devices can be easily mounted to the end faces of the guide rails facing the door opening. The spacer rollers prevent the held door elements from colliding with the spacer device body or the guide rails.

[0038] The first door magnet parts or the first and second door magnet parts preferably extend in a plate-like shape parallel to the axis of travel of the mounting profile, so that the magnetic coupling between the door magnet parts and the corresponding device magnet parts is preferably maintained unchanged over the entire range of displacement or over a critical area within the door compartment when the door element or door elements are moved.

[0039] 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 of the first and second door element, preferably screwed, clamped, glued or potted.

[0040] Furthermore, the door magnet components are preferably covered with covers so that they are not visually perceptible. The door magnet components and the covers are preferably completely recessed into the door elements, so that the door elements have a flat surface across their entire area.

[0041] Preferably, the door magnet components or their covers form the running surfaces for the spacer rollers. This ensures that the spacer rollers can roll on ideal running surfaces without wear and noise.

[0042] The first door magnet parts connected to the first door element preferably extend directly or at a small distance from the front end face of the first door element, away from the mounting profile, completely or partially across the width of the first door element.

[0043] The second door magnet parts connected to the second door element preferably extend directly or at a small distance from the rear end face of the second door element connected to the first door element, completely or partially across the width of the second door element.

[0044] The body of the spacer device is preferably made of metal or plastic and is positively or frictionally connected, optionally by magnetic force, to the associated first device magnet part or to the first and second device magnet parts. Preferably, the body has shaped elements by which the device magnet parts are positively retained. If the 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 body. For example, the device magnet parts have a bore through which a connecting screw is passed and screwed into a threaded bore in the body.

[0045] 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 optimal magnetic interaction is achieved.

[0046] The door magnet parts or device magnet parts designed as permanent magnets are preferably rare-earth magnets, which consist essentially of, for example, ferrous metals (iron and / or cobalt and / or nickel) and rare-earth metals (in particular neodymium, samarium, praseodymium, dysprosium, terbium, or gadolinium).

[0047] The spacer devices preferably have different functions and elements. Preferably, the spacer devices include adjustable or non-adjustable coupling elements for attaching the holding device and / or stop elements or damping elements that can interact with the guide rollers. Preferably, the adjustable buffer devices are mechanically coupled to the spacer rollers.

[0048] The spacer devices used can be identical or partially identical, so that they can be manufactured cost-effectively.

[0049] The functional unit can be a piece of furniture, for example a cabinet, or a room unit, such as a kitchen, a room or a bedroom, which is closed off by at least one single or multi-part door that can be parked in a door compartment.

[0050] The invention is explained in more detail below with reference to the drawings. These show: Fig. 1 shows a functional unit 1 according to the invention in the embodiment of a piece of furniture with a first door compartment 18, in which a mounting profile 14, which is connected to a folding sliding door 11, is moved by means of a sliding device 10 (see Fig. 3 ) is held slidably, and a second door compartment 18 in which a further mounting profile 14, which is connected to a one-piece door 11, is held slidably by means of a sliding device 10; Fig. 2 the in the first door compartment 18 of the functional unit 1 of Fig. 1 The arranged sliding device 10 with the mounting profile 14, which is slidable along an upper and a lower guide rail 15, 16, on which upper and lower spacer devices 7, 8 are mounted on the front, each having two spacer rollers 791, 792; 891, 892 and each having two device magnet parts 771, 772; 871, 872, which interact with associated door magnet parts 851, 852, which are connected to door elements 111, 112 of the folding sliding door 11 and preferably recessed therein (see Fig. 4b ); Fig. 3 the sliding device 10 of Fig. 2 from the other side with a preferred holding device 4 and an optionally provided drive device 2; Fig. 4 the upper spacer holding device 7 of 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 plate-shaped door magnet parts 751, 752 recessed into the door elements 111, 112; Fig. 4b the upper spacer holding device 7 of Fig. 4a after the assembly of the device magnet parts 771, 772; Fig. 5 the upper and the lower spacer holding device 7, 8 of Fig. 2 In a preferred embodiment, provided for guiding a door 11 with only one door element 111; Fig. 6 shows the upper spacer holding device 7 of Fig. 5 , which is held by the upper guide rail 15; Fig. 6b the lower spacer holding device 8 of Fig. 5 , which is held by the lower guide rail 16; Fig. 7 a part of the sliding device 10 of Fig. 2 with the upper spacer device 7 in a preferred embodiment; and Fig. 8 the upper spacer device 7 of Fig. 7 in exploded view.

[0051] Fig. 1 Figure 1 shows a functional unit or piece of furniture 1 according to the invention, in the form of a cabinet in which a door compartment 18 is integrated on each side. The piece of furniture 1 comprises side walls 1A, a top panel 1B, a bottom panel 1C, and intermediate walls 1D, each of which, together with an associated side wall 1A, defines a door compartment 18. A sliding device 10 according to the invention, with a mounting profile 14, is arranged in each door compartment 18. This device can be moved manually or by means of a drive device (see Figure 1). Fig. 3 The drive device 2) is automatically movable within the door compartment 18. Doors 11 are held by the mounting profiles 14 of the sliding devices 10, and these doors are moved into or out of the corresponding door compartment 18 when the mounting profile 14 is moved. When the door 11 moves out of the respective door compartment 18, the mounting profile 14 is moved along a running axis x from the rear 181 of the door compartment 18 to an entrance opening 180 of the door compartment 18.

[0052] In the first door compartment 18, a folding sliding door 11 is held, which has a first and a second door element 111, 112 that are hinged to each other and foldable against each other. The door 11 held in the second door compartment 18 by the mounting profile 14 within the second door compartment 10, however, has only one door element 111. The first door element 111 has an inner side 1111 and an outer side 1112. The second door element 112 has an inner side 1121 and an outer side 1122 (see Fig. 4b ).

[0053] In Fig. 1 The folding sliding door 11 is fully extended from the first door compartment 10 and fully unfolded, so that the door elements 111, 112 are aligned in one plane and only their outer surfaces 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 the folding sliding door 11, shown in the closed position, covers two-thirds of the cabinet opening 100.

[0054] The trailing rear end face 1115 of the first door element 111 of the folding sliding door 11 when the sliding door 11 is extended is connected by stop hinges 131 to the mounting profile 14, symbolically shown by a dashed line.

[0055] The leading front face 1116 of the first door element 111 is connected by door hinges 132 to the rear face 1125 of the second door element 112, the front face 1126 of which is connected at the top to a front track assembly 5F. The front track assembly 5F is guided in a support rail 17, which has curved sections and support rail sections 171 on both sides that extend into the door compartments 18. When entering the door compartment 18 and when traveling along the support rail 17, the front track assembly 5F always leads within its assigned path, with the change of direction occurring within the curved section.

[0056] Functional units 1 according to the invention have at least one spacer device 7, 8. Fig. 1 The figure schematically shows that in this preferred embodiment of the functional unit 1 each of the sliding devices 10 has an upper spacer device 7 and a lower spacer device 8, which allow the doors 11 or the door elements 111, 112 to be guided and held precisely.

[0057] Fig. 2 shows the functional unit 18 in the first door compartment of Fig. 1 The arranged sliding device 10 with the folding sliding door 11, whose door elements 111, 112 are shown in section to reveal the spacer devices 7 and 8. The door elements 111, 112, which are connected to each other by door hinges 132 shown schematically, are aligned parallel to each other and can be inserted into the door compartment 18 in this orientation.

[0058] The mounting profile 14 is connected to the first door element 111 by stop hinges 131 and is held slidably in a vertical orientation by a holding device 4 (symbolically shown by dashed lines). The holding device 4 can be designed as desired and, for example, be in the form of a scissor cross, a parallelogram, or preferably in a device with retaining cables as shown. Fig. 3 to be realized.

[0059] The mounting profile 14 is connected at its upper end to an upper guide carriage 5, which is guided in an upper guide rail 15, and at its lower end to a lower guide carriage 6, which is guided in a lower guide rail 16. The upper guide carriage 5 comprises support rollers 591 and guide rollers 592 and, in addition to its guiding functions, also has a load-bearing function. The lower guide carriage 6 comprises guide rollers 692, which are guided in the lower guide rail 16 (see Fig. 3 ).

[0060] The upper guide carriage 5 and the lower guide carriage 6 are located directly in front of the entrance opening 180 of the door compartment 18. The carriage body 51 of the upper guide carriage 5 rests against a buffer device or damper device 3, which is mounted in the upper guide rail 15.

[0061] The upper guide rail 15 holds an upper spacer device 7 at the front and the lower guide rail 16 holds a lower spacer device 8 at 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 each other.

[0062] 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. 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.

[0063] The first spacer rollers 791, 891 keep the first door element 111 at a distance and can roll along its inner surface 1111. The second spacer rollers 792, 892 keep the second door element 112 at a distance and can roll along its inner surface 1121. Therefore, the two door elements 111, 112 cannot strike the inside against the fixture bodies 71, 81 of the spacer devices 7, 8 or against the guide rails 15, 16.

[0064] The first device magnet parts 771, 871 interact 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 interact 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 and the first and second door magnet parts 751, 851; 752, 852 interact magnetically and exert forces on each other, by 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 inner surfaces 1111, 1121 of the first and / or second door element 111, 112 and preferably run on the door magnet part 751, 851 there. 752, 852 or a cover 76, 86 provided on the door magnet part 751, 851; 752, 852, which are preferably designed as running surfaces.As mentioned, at least one of the corresponding device magnet parts 771, 871; 772, 872 and the door magnet parts 751, 851; 752, 852 is 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 can be permanently magnetic.

[0065] When sliding into or out of door compartment 18, the two door elements 111, 112 are guided and held with minimal or virtually no play by means of the two spacers 7, 8. In particular, even after the two door elements 111, 112 have moved into door compartment 18, their end faces 1116, 1125, which are connected to each other by the door hinges 132, are held securely by the spacers 7, 8. The door elements 111, 112 are therefore held securely both during movement and when stationary and cannot strike the guide rails 15, 16 inwards, nor can they strike a side wall 1A or a partition 1D outwards (see Fig. 1 ).

[0066] The sliding device 10 can be used to hold a one-piece or multi-piece door 11. With reference to Fig. 2 The use of the sliding device 10 in combination with a door with two door elements 111, 112 was described. The spacer devices 7, 8 according to the invention, however, can also be used only for guiding one door element 111 of a one-piece door 11 or the first door element 111 of a multi-piece door 11. Fig. 5 shows part of a sliding device 10, which is intended for guiding only one door element 111.

[0067] Fig. 3 The sliding device 10 shows Fig. 2 with a preferred holding device 4 and an optionally provided drive device 2 from the other side.

[0068] The holding device 4 comprises a first front-facing rope connection device 84, a first lower roller unit 431 arranged at the lower end of the mounting profile 14, a first upper roller unit 411 arranged at the upper end of the mounting profile 14, and a first rear-facing rope connection device 44 arranged at the rear end of the upper guide rail 15, as well as a first holding rope 421 which is connected at a first end piece to the first front-facing rope connection device 84, guided counterclockwise around the first lower roller unit 431 and clockwise around the first upper roller unit 411 and connected at a second end piece to the first rear-facing rope connection device 44.

[0069] Furthermore, the holding device 4 comprises a second front-facing rope connection device 74, a second upper roller unit 412 arranged at the upper end of the mounting profile 14, a second lower roller unit 432 arranged at the lower end of the mounting profile 14, and a second rear-facing rope connection device 45 arranged at the rear end of the lower guide rail 16, as well as a second retaining rope 422 which is connected at a first end piece to the second front-facing rope connection device 74, guided clockwise around the second upper roller unit 412 and counterclockwise around the second lower roller unit 432, and connected at a second end piece to the second rear-facing rope connection device 45.

[0070] The preferably adjustable first front-facing cable connection device 84, by means of which the first tension cable 421 can be tensioned to vertically align the mounting profile 14, is integrated into the lower spacer device 8. The second front-facing cable connection device 74 is integrated into the upper spacer device 7. The two rear cable connection devices 44, 45 preferably each have an entry roller through which the respective retaining cable 421, 422 can be inserted into a housing. Preferably, a tension spring is provided in the second rear-facing cable connection device 45, via which a constant tensile force can be transmitted to the second retaining cable 422.

[0071] In the holding device 4 according to the invention, preferably one of the holding cables 421, 422, or in this embodiment the second holding cable 422, is always held elastically. After installation, the first holding cable 421, however, is held inelastically or rigidly by the first front-facing cable connection device 84 and the first rear-facing cable connection device 44. The first front-facing cable connection device 84 is adjustable to tighten the first holding cable 421 and to align the mounting profile 14 vertically.

[0072] Furthermore, the sliding 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 by way of example and preferably used comprises a drive unit 21 with a drive element and an associated pulley onto which a pull rope 22 is wound. The drive element is, for example, a spiral spring or a helical spring that is tensioned or relaxed when the pulley rotates. The pull rope 22 can therefore be pulled off the pulley by applying force and is automatically wound back onto the reversing pulley.

[0073] The pull rope 22 is guided via a first deflection pulley 23, which is rotatably mounted on a deflection unit 230, and a second deflection pulley 24 to a pull rope connection 72, which is located on the upper spacer device 7. The deflection unit 230 is slidable along the mounting profile 14 and can optionally be fixed in place. By moving the deflection unit 230, a desired tensile tension can be applied to the pull rope 22.

[0074] In Fig. 3 The mounting profile 14 was moved almost to the rear 181 of the door compartment 18, which is why the pull cable 22 was extended further and the drive element was tensioned. As soon as the pull cable 22 is released again, the cable pulley is rotated back by the tensioned drive element.

[0075] By connecting the drive device 2 to the mounting profile 14 or the guide carriage 5, it is no longer necessary to mount the drive device 2 to a rear wall, a partition wall 1D, or a side wall 1A of the functional unit 1. A particular advantage is that the sliding device 10, together with the holding device 4 and the drive device 2, can be installed in door compartments 18 of different dimensions without modification. Only the lengths of the retaining cables 421, 422, and the pull cable 22 need to be adjusted accordingly.

[0076] 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, which has been moved to the opening 180 of the door compartment 18, can be locked in order to carry out maintenance work or to make adjustments.

[0077] Fig. 4a The upper spacer device 7 shows 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 recessed into the door elements 111, 112 and the covers 76 lying on them in sectional view. The device body 71 of the spacer device 7 includes on its upper side a mounting bar 711, which is 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 dashed lines.

[0078] Provided that the upper and lower guide rails 15, 16 have the same or at least functionally equivalent receiving channel, the upper spacer device 7 can be rotated 180° and used as the lower spacer device 8, for example, when using a scissor cross as a holding device 4. The spacer device 7 can also be connected to a device magnet part 771 on only one side if only one door element 111 is to be moved into the door compartment 118.

[0079] In this preferred embodiment, the device body 71 has threaded bores on both sides into which connecting screws 78 can be screwed 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 element 781 is provided between the connecting screws 78 and the device magnet parts 771, 772, which elastically transmits the clamping 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 by other means, either by frictional or positive locking. For example, the device magnet parts 771, 772 can be inserted into recesses in the device body 71, for example, glued and / or potted, or held only 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.

[0080] The first plate-shaped door magnet 751 is arranged within a door recess 1110 on the inside 1111 of the first door element 111 and is 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 752 is arranged within a door recess 1120 on the inside 1121 of the second door element 112 and is 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.

[0081] The cover 76 can be made of metal, plastic, or wood, for example. Alternatively, the cover 76, for example a film or a panel, can cover the entire inner surface 1111, 1121 of the door elements 111, 112. In preferred embodiments, the cover 76 therefore forms a coating of the door elements 111, 112.

[0082] Fig. 4b The upper spacer device 7 shows Fig. 4a After the assembly of the device magnet parts 771, 772, the upper guide carriage 5 with the support rollers 591 and the guide rollers 592 is shown in this illustration instead of the upper guide rail 15. It can be seen that the door elements 111, 112 shown in the sectional view are held 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. Thus, the door 11 is held precisely both when moving and when stationary.

[0083] 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 door element 111, from which a central section has been cut out. The spacer devices 7, 8 are consequently provided on only one side each with a spacer roller 791, 891 and a device magnet part 771, 871. The upper guide rail 15 and the lower guide rail 16, which hold the upper and lower spacer devices 7, 8 at the front, are shown in abbreviated form. Door recesses 1110 are provided on the inside 1111 of the door element 111, extending almost over the entire width of the door element 111. A portion of the plate-shaped upper door magnet part 751 has been cut away to reveal the door recess 1110. The plate-shaped door magnet parts 751, 752 have bores 7510, 8510 into which mounting screws 7511 are inserted. The covers 76, 86 extend over the entire length of the door recesses 1110.

[0084] Fig. 6a The upper spacer device 7 shows Fig. 5 , which is held by the upper guide rail 15. The upper guide rail 15 has a mounting channel 150 on its underside, into which a mounting beam 711, connected to the fixture body 71 of the upper spacer 7, is inserted. The inserted mounting beam 711 is locked or clamped by means of locking screws 712. Above the mounting channel 150, the upper guide rail 15 has a cross-section within which the upper guide carriage 5 can be moved up to a buffer device or damper device 3.

[0085] The device magnet part 771, which is set back from 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, or 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.

[0086] The spacer roller 791 is rotatably mounted in a roller holder 715 by means of a bearing shaft 790. The roller holder 715 is preferably positively engaged in a bearing chamber 716 of the device body 71, either fixed or slidably, and is secured by means of a mounting screw or adjusting screw 713. Preferably, the roller holder 715 is slidably mounted and can be selectively positioned by means of the adjusting screw 713.

[0087] It should be noted that in this preferred embodiment, the spacer roller 791 projects beyond the device body 71 not only on the side of the associated device magnet part 78 but also on the front side. The door element 111 is therefore guided and held at a distance from the device body 71 not only during axial displacement within the door compartment 18 but also during pivoting movement at the exit of the door compartment 18.

[0088] Fig. 6b The lower spacer device 8 shows 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 fixture body 81 of the lower spacer device 8, is held. The lower roller support 815 is also slidably mounted and comprises a buffer body 8153, which holds a buffer element 8154 and which is guided through an opening in the fixture body 81.

[0089] The lower and upper spacer devices 7, 8 are therefore fundamentally interchangeable. Furthermore, the spacer devices 7, 8 can advantageously include additional functional elements, such as preferably adjustable buffer devices, damping devices, a stop device, a locking lever 83, and cable connection devices 84.

[0090] Fig. 7 shows part of the sliding device 10 of 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 bracket 715, which is slidably mounted within a bearing chamber 716 of the device body 71 and can be selectively moved by means of an adjusting screw 713. The guide carriage 5, guided within the upper guide rail 15, is advanced with the carriage body 51 to the damping device 3.

[0091] Fig. 8 shows the upper spacer holding device 7 of Fig. 7In exploded view. The roller holder 715 comprises guide ribs 7151 on its underside and top surface, which are guided in corresponding guide tracks 718 of the bearing chamber 716. The roller holder 715 is also preferably integrally connected to a buffer piston 7153, on the front of which a buffer element 7154 is held. The spacer roller 791 and the buffer element 7154 are therefore preferably rigidly coupled to each other, so that when the end stop of the upper guide carriage 5 is adjusted, the first spacer roller 791 is simultaneously optimally positioned and does not need to be positioned separately. In addition, the roller holder 715 comprises a retaining flange 7152, by means of which the head of the adjusting screw 713 is rotatably but axially displaceably held 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 to turn the adjusting screw 713.

[0092] The device body 71 has a bearing chamber 716 into which the roller holder 715 can be inserted. A transfer opening 717 is provided on the rear wall of the bearing chamber 716, through which the buffer piston 7153 with the buffer element 7154 is guided. A threaded bore 719 is also provided on the rear wall of the bearing chamber 716, into which the adjusting screw 713 is screwed. By turning 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.
