The slatted wall assembly comprises a panel with re-entrant channels on the front of the panel. A utility line for connecting to an equipment is routed along a channel in a groove on the side of the channel, so that it is not visible.
[0012] EP 3 643 209 A1 relates to an arrangement comprising a suspension profile and a suspension element that can be suspended therein. The suspension profile comprises a first retaining rail and a second retaining rail, on which the suspension element rests in a contacting position and contacts a contact surface of at least one electrical conductor, which is electrically insulated from the first and second retaining rails via an insulator and a fastening section for mounting the suspension profile on a base.
[0013] DE 201 18 482 U1 relates to a kitchen hanging system with at least one rail arranged on a wall and at least one hanging module fastened to the rail or assigned to the rail. The rail has at least one guide channel, to which either a planar lighting module for illuminating a space in front of the wall is assigned and / or is movably arranged in the holding module for accommodating kitchen appliances and / or foodstuffs, wherein the holding module is fastened to the rail without moment, at least when arranged alone. DE 10 2012 023 303 A1 relates to a furnishing system, in particular kitchen furnishing systems, with at least one structural element and at least one element that can be arranged on the structural element, wherein the structural element has a wave geometry, on which the element can be arranged in different positions.
[0014] The object of the present invention is to further develop a fastening device of the type mentioned at the outset in such a way that the objects are held securely and reliably on the wall with simple assembly of the fastening device and, in addition, the possibility of electrifying the objects is provided.
[0015] Furthermore, a wall-mounted kitchen system and / or an object in the form of a wall cabinet or shelf, in particular a kitchen cabinet, with an integrated fastening device and / or integrated supply duct is to be provided.
[0016] The object is achieved according to the invention, inter alia, by a fastening device for hanging an object, such as a wall cupboard or shelf, on a body, such as a wall, comprising a first holding element extending in the longitudinal direction, which can be fastened to the object, a second holding element extending in the longitudinal direction, which can be fastened to the body, wherein the object, in the state of use, is suspended from the second holding element via the first holding element, and a supply channel for receiving at least one supply line, in particular a power line.
[0017] The invention is characterized in that the supply channel is a hollow space delimited in the state of use by a section of the first holding element and a section of the second holding element.
[0018] The fact that the supply duct is a hollow space delimited by a section of the first holding element and a section of the second holding element has the advantage that the individual holding elements do not have to be designed as closed hollow profiles, which means that material can be saved overall. In the use state, a passage in the form of a gap or a longitudinal slot for the wall-side passage of the supply line is formed between a lower edge of the lower section or base section of the second holding element and an upper edge of the second leg. The longitudinal slot makes it possible to introduce a supply line, which for example is led out of the wall, into the supply duct over the entire length of the supply duct, which enables simple installation.Conversely, the supply line can be led out of the supply duct at any point along the duct, for example to connect to a wall socket.
[0019] In a preferred embodiment, it is provided that the first holding element is a profile rail or a section thereof, comprising a first leg, a second leg and a web connecting the legs, that the second holding element is a profile rail or a section thereof, comprising a section which can be fastened to the body and a support element extending from the section which, in the state of use, interacts with the first holding element at least in a force-fitting manner, wherein the hollow space is delimited by the second leg and a section of the web of the first holding element and a lower section and a section of the support element of the second holding element.
[0020] In a particularly simple manner, the cavity forming the supply channel is thus delimited by the second leg and a section of the web of the first holding element and a lower section and a section of the support element of the second holding element.
[0021] In order to easily connect an interior of the object, such as a kitchen cupboard, to the supply line, it is provided that a passage into the interior is formed in the second leg or the lower section of the web of the first holding element.
[0022] The profile rail of the first holding element has a rectangular, in particular square, outer profile. Due to the rectangular, in particular square, outer profile, the first holding element can be easily arranged in a receiving channel of the object, such as a wall cabinet or shelf, and secured therein, e.g., using fastening elements such as screws or adhesive.
[0023] Alternatively, the profile rail of the first support element can be surrounded on the outside by a plastic surround, such as fiber-reinforced polyethylene, such as overmolded, wherein the plastic surround preferably has a rectangular, in particular square, outer profile. The plastic surround allows wood screws to be used to attach the first support element, further simplifying installation. Alternatively, it is of course also possible for the profile rail overmolded with the plastic surround to be glued into the receiving channel of the wall cabinet or shelf.
[0024] To improve stability, it is provided that the support element extending from the section or base section of the second holding element is designed in the form of a web which, in the state of use, engages in a recess formed in the web of the first holding element, such as a groove or longitudinal slot, or interacts with a projection extending from the web in a force-fitting and / or form-fitting manner.
[0025] Furthermore, the second leg of the first holding element is long enough to rest against the body, such as a wall, when in use. This also achieves improved stability compared to the prior art.
[0026] In a particularly preferred embodiment, the supply channel terminates at each end with a connector that is connected to the supply line in the form of the power line. This allows objects suspended next to each other to be electrically connected to one another via connectors.
[0027] An independent invention relates to a wall-mounted kitchen system, comprising juxtaposed functional modules with a first support element and a second support element, such as a wall rail, on which the functional modules are suspended by the first support element, as well as a supply channel for accommodating at least one supply line, in particular a power line. The wall-mounted kitchen system is characterized in that the supply channel is a hollow space delimited, in use, by a section of the first support element and a section of the second support element. A separate supply channel or support elements specifically designed as a supply channel are not required.
[0028] The holding elements are designed in such a way that when the second holding element (male part) is inserted into the first holding element (female part), a hollow space is formed that can be used as a cable duct. Electrical cables can be laid in the cable duct, via which electrical devices inside the cabinet body can be connected with energy and / or data via a data network such as the Internet. Devices can be, for example, lights, sensors or actuators. Motion sensors or cameras are conceivable as sensors, by means of which the interior of a cabinet can be detected. Actuators can be motors for opening and closing doors or
[0029] Drawers. Lighting can be provided by LED lights or illuminated or dimmable (from transparent to opaque) panels in cabinet doors. Sensors can also be used to measure the weight of a cabinet or shelf, for example, to determine the consumption of a product or the quantity of certain items. The connection of cabinets and their contents, as well as appliances such as microwaves, refrigerators, sinks, and / or stoves, to a "smart home" environment is significantly simplified by the cable duct according to the invention.
[0030] A particularly preferred embodiment is characterized in that the first holding element is a profile rail or a section thereof, comprising a first leg, a second leg and a web connecting the legs, that the second holding element is a profile rail or a section thereof, comprising a section which can be fastened to the body and a support element extending from the section which, in the state of use, interacts with the first holding element at least in a force-fitting manner, wherein the hollow space is delimited by the second leg and a section of the web of the first holding element and a lower section of the base section and a section of the support element of the second holding element.Furthermore, the wall-mounted kitchen system is characterized by the fact that each supply duct ends with a connector that connects to the supply line in the form of a power cable. The connectors connect adjacent functional modules. The supply duct for the electrical supply is designed to be used with a plug-in system to easily connect the various functional modules, such as kitchen cabinets.
[0031] To supply the interior of the functional modules with electrical energy, for example, a feedthrough is provided in the second leg or the lower section of the web of the first holding element, through which the supply line is routed into the interior of the functional module. An electrical line can be routed through the feedthrough into the interior of the functional module, for example, to supply electrical devices such as lights, fans, sensors, electric refrigerators, microwaves, extractor hoods, steam cookers, ovens, and stoves.
[0032] In order to flexibly decide at any time along the entire length of the supply duct where an electrical cable should be laid in the wall, a feedthrough in the form of a longitudinal slot or gap is provided between a lower edge of the base section of the second retaining element and an upper edge of the second leg of the first retaining element for the wall-side feedthrough of the supply cable. The feedthrough in the form of a longitudinal slot or gap also offers the advantage that multiple wall connections can be integrated into the supply duct over the entire length of the duct or can be led out of the duct.
[0033] Another independent invention relates to a wall-mounted kitchen system, comprising at least one functional module having a first holding element and a second holding element, such as a wall rail, which is fastened to a wall and on which the at least one functional module is suspended with the first holding element.
[0034] Such a wall-mounted kitchen system is distinguished from the prior art in that the first holding element is a profile rail or a section thereof, comprising a first leg, a second leg and a web connecting the legs, in that the second holding element is a profile rail or a section thereof, comprising a section which can be fastened to the wall and a support element extending from the section, wherein an upper part of the section of the second holding element has a recess or a slope pointing away from the body, into which a projection of an L-shaped end of the first leg engages in a form-fitting and force-fitting manner in the use state, and wherein the support element extending from the section interacts with the first holding element in an at least force-fitting manner in the use state.
[0035] This design is particularly suitable for wall-mounting functional modules in the form of kitchen cabinets, especially wall-mounted kitchen cabinets for refrigerators, dishwashers, stoves, etc. The special design of the first and second retaining elements allows for very heavy functional modules to be suspended securely and easily. The special design of the profile rail also takes into account the fact that the functional modules accommodating the aforementioned appliances have a depth in the range of 60-80 cm, usually at least 65 cm, and thus a high torque load is placed on the retaining elements.
[0036] Preferably, the first holding element is arranged in a receiving channel preferably formed on the wall side of an upper edge of the functional module.
[0037] It is provided that the profile rail of the first holding element has a rectangular, in particular square, outer profile.
[0038] For easy assembly of the profile rail, it is provided that the profile rail of the first holding element is surrounded on the outside by a plastic frame, such as fiber-reinforced polyethylene, as if overmolded, wherein the plastic frame preferably has a rectangular, in particular square, outer profile.
[0039] The plastic surround provides the advantage that the profile rail can be attached to the body of the functional module using standard wood screws. Separate metal screws are not required. To further stabilize the fastening element, the support element extending from the section of the second retaining element is designed in the form of a web. In use, the support element engages in a recess formed in the web of the first retaining element, such as a groove or longitudinal slot, or interacts with a projection extending from the web in a force-fitting and / or positive-locking manner.
[0040] In other words, an "L-slot" is formed, i.e., an L-shaped projection of the second retaining element (male part), which provides additional support. A total of three contact points or surfaces are provided between the second retaining element and the first retaining element (male and female parts): first, an inclined section in the upper area and a substantially vertical section, and then, in the central area, the L-slot.
[0041] A further constructive improvement results from the fact that the second leg of the first holding element has a length such that it rests against the body, such as a wall, in the state of use.
[0042] The designs according to the invention differ from known designs in that they are more stable and can support large and widely projecting loads. For example, the first support element can have dimensions of, for example, 85 mm in depth and 155 mm in height. These "heavy" designs are particularly suitable for mounting widely projecting loads, such as kitchen cabinets, i.e., wall cabinets, and base cabinets.
[0043] Compared to known designs, the advantage is that warping or bending is excluded, thus ensuring faster and safer assembly.
[0044] Preferably, the first retaining element (female part) has a first leg, which, in its lower wall-side portion, is designed as a support against the wall. It is also possible for the first and second retaining elements to be glued together. This means that a tensioning element is not absolutely necessary for both base-side and head-side bracing.
[0045] However, bracing with a tensioning element is the preferred embodiment so that the kitchen cabinets can be dismantled without causing damage to the wall.
[0046] The second retaining element can be injected in a fiber-reinforced polyurethane material or partially overmolded with such a material. This material is firmly bonded to the surface of the aluminum profile. The advantage of this design is that these profiles can be more easily connected to wooden panel elements of a piece of furniture, such as a kitchen cabinet.
[0047] A further preferred embodiment is characterized in that a metal plate, designed as a spacer element, is arranged in a lower leg of the first holding element. The metal plate is operatively connected to a screw, wherein turning the screw causes a horizontal displacement of the plate such that the plate moves out of the leg when, for example, it is turned clockwise, and moves into the first holding element when, for example, it is turned counterclockwise. This allows the "kitchen bracket" fastening device to be aligned even if the wall is uneven.
[0048] Furthermore, the invention relates to a method for hanging functional modules of a wall-mounted kitchen system, wherein functional modules are suspended with a first holding element, preferably next to one another, on a second holding element, such as a wall rail.
[0049] According to the invention, it is provided that a profile rail or a section thereof is used as the first holding element, comprising a first leg, a second leg and a web connecting the legs, that a profile rail or a section thereof is used as the second holding element, comprising a section that can be fastened to the body and a support element extending from the section, wherein an upper part of the section of the second holding element has a recess or a slope pointing away from the body, into which a projection of an L-shaped end of the first leg is hooked in a form-fitting and force-fitting manner in the use state, and wherein the support element extending from the section interacts with the first holding element at least in a force-fitting manner in the use state.

[0064] Fig. 11 a perspective view of a wall-mounted kitchen system.
[0065] Fig. 1 shows a side view of an arrangement of objects 10, 12 that are attached to a wall 16 by means of a fastening device 14. The objects can be cabinets, such as kitchen base cabinets or kitchen wall cabinets, that are suspended, particularly in a suspended, manner. For example, in the example shown, the kitchen base cabinet 10 is suspended from the wall 16 at a distance from a floor 18. The objects can be any type of object, such as shelves, pictures, lamps, etc.
[0066] The fastening device 14 comprises a first holding element 20, which is arranged, as fastened, on the object 10, 12 and a second holding element 22, which is arranged, as fastened, on the wall.
[0067] The first holding element 20 is arranged in and secured to a receiving channel 24 formed in the object 10, 12, preferably at an upper edge. The attachment can be achieved via fastening elements 26, such as screws, or alternatively by clamping or gluing.
[0068] The first holding element 20 and the second holding element 22 are designed as profile strips extending in the longitudinal direction and have sections 28, 30 with at least partially corresponding cross sections, which can be brought into positive engagement with one another at least partially.
[0069] According to one aspect of the invention, a longitudinally extending cavity is formed as a cable duct 32 in the first holding element 20, the second holding element 22, and / or between the first and second holding elements 20, 22. At least one passage 34 extends from the cable duct 32 into an interior 36 of the cabinet 10, 12, through which passage an electrical cable accommodated in the cable duct 32 for operating an electrical device 38, such as a light, sensor, camera, or other electrical device, can be passed. Furthermore, at least one passage 40 extends from the cable duct 32 toward the wall 16, through which passage electrical cables emerging from the wall 16 can be introduced into the cable duct 32.
[0070] In the illustrated embodiment, the kitchen cabinet 10, 12 comprises a body 42 with a top 44, in whose wall-side end the receiving channel 24 is arranged. In the illustrated embodiment, the top 44 of the body 42 is covered with a worktop 46, which terminates on the wall side with a base 48.
[0071] Fig. 2 shows a side view of the pre-machined body 42 for the kitchen cabinet 10, 12 with the receiving channel 24 for the fastening device 14.
[0072] Fig. 3 shows a side view of a first embodiment of the fastening device 14. In the illustrated embodiment, the first holding element 20 consists of a preferably metallic profile rail 50 which, according to one aspect of the invention, is surrounded on the outside by a plastic border 52, for example a fiber-reinforced polyethylene. The application of the plastic border 52 can be carried out using a coextrusion process. The plastic border 52 preferably has a rectangular cross-section on the outside, which is adapted to an inner cross-section of the receiving channel 24. The plastic border 52 allows simple fastening of the first holding element 20 using, for example, wood screws in the receiving channel 24. To fasten the first holding element 20, the fastening elements 26, such as wood screws, are screwed into the plastic border 52 through wooden wall elements of the body 44 that delimit the receiving channel 24.
[0073] The profile rail 50 is essentially C-shaped, with a first, lower leg 54, a second, upper leg 56, and a web 58 connecting the two legs 54, 56. According to a further aspect of the invention, a fastening element 59, such as a grub screw, can be provided to secure the first holding element 20. This fastening element 59 penetrates the upper wooden panel element 44 of the body 42, the plastic surround 52, and the first leg 56, connecting these elements to one another. After the first holding element 20 is secured, the cover or worktop 46 can be mounted.
[0074] The C-shaped first retaining element 20 has a longitudinally extending opening 60 on the wall side, by means of which the first retaining element 20 can be suspended into the second retaining element 22. As a result, the first and second retaining elements 20, 22 can be brought into at least partial positive engagement with one another.
[0075] According to a further aspect of the invention, a projection 64 extends from a surface 62 of the profile rail 50 facing away from the opening 60, which projection is enclosed, as if overmolded, by the plastic surround 64. This achieves a good connection between the profile rail and the plastic surround, as well as high stability.
[0076] The second retaining element 22, which is designed as a profile rail, rests against the wall 16 with a first section 66 and is fastened to the wall 16 by means of fastening elements 67, such as screws. In an upper part of the section 66, a wall-side recess 68 is provided, into which a projection 70 of an L-shaped end 72 of the second leg 56 engages. The recess 68 and the projection 70 form the corresponding cross sections via which the retaining elements 20, 22 can be positively connected.
[0077] According to a further aspect of the invention, a web 76 extends from a surface 74 of section 66 facing the first holding element 20, which surface runs essentially parallel to the surface of section 66 abutting the wall. The web 76 abuts against an inner wall 78 of the profile rail 50 and is bent at the bottom against a projection 80 extending from the inner wall 78. The cable duct 32 is thus formed between the web 76, the inner wall 80, and the first leg 54 of the profile rail 50. The cable or supply duct 32 is a hollow space delimited in the use state by a section, such as the inner wall 80, of the first holding element 50 and a section of the second holding element 22.
[0078] Fig. 4 shows a further embodiment of a fastening device 82 according to the invention, which is arranged in the receiving channel 24 of the body 42 of the cabinet 10, 14. The fastening device 82 comprises a first holding element 84 and a second holding element 86, each of which is designed in the form of a preferably metallic profile rail. The first holding element 84 has a substantially rectangular outer profile, which is received directly in the receiving channel 24 and fixed therein via fastening elements 88, such as screws. The screws 88 can be designed as wood screws or metric screws that engage in a thread or threaded sleeve 90 arranged in the profile rail. The first holding element 84 is C-shaped and comprises a first, lower leg 92 and a second, upper leg 94, which is L-shaped.
[0079] The second retaining element 86 is attached to the wall 16 via fastening elements 96, such as screws. A wall-side recess 10 is formed in an upper section 98 of the second retaining element 86 to form a cross-sectional area. Correspondingly, the second leg 94 of the first retaining element 84 has an L-shaped projection 102, which engages in the recess 100 during the positive connection. This creates a force-locking and positive connection.
[0080] Additionally, a screw connection 103 can be provided. The screw 103 penetrates the wooden panel element 44 of the body 42, the second leg 94 of the first retaining element 86, and engages the section 100 of the second retaining element to further secure it. The screw 103 can engage a thread or a threaded sleeve 104 arranged in one or both of the profiles 84, 86.
[0081] Furthermore, according to an inventive aspect, a longitudinally extending recess 108, such as a longitudinal groove, is formed in an inner wall 106 of the first retaining element 84, into which a web 110 extending from the second retaining element 86 engages. The web 110 can be additionally secured by a fastening element 112, such as a screw, extending from the wooden panel element 44 of the receiving channel 24. The fastening elements 103 and 112 are not mandatory.
[0082] In this embodiment, the cable duct 32 is formed as a hollow space between the first retaining element 84 and the second retaining element 86. This hollow space is defined by the first, lower leg 92, the inner side 106 of the first retaining element 86, the web 110, and a section 114 of the second retaining element 86.
[0083] Fig. 5 shows a side view of a first variant 500 of the fastening device 82 according to Fig. 4. A first retaining element 502 comprises a first leg 504 and a second leg 506, which are connected to one another via a web 508. Outer surfaces of the first leg 504, the second leg 506, and the web 508 form a rectangular contour. A second retaining element 510 is positively received in the first retaining element 502.
[0084] A surface 512 of the second leg 506 facing the second holding element 510 has a cross-section that at least partially corresponds to a cross-section of a surface 514 of the second holding element 510. The corresponding surfaces 512, 514 comprise a straight section 516 that runs parallel or substantially parallel to the first leg 504, a surface 518 that rises toward the connecting web 508 at an angle of preferably 45°, which merges into a surface 520 that runs parallel to the first leg 504.
[0085] An inner surface 522 of the connecting web 508 extends perpendicular to the surface 520. According to a further aspect of the invention, a longitudinally extending groove 524 is formed in this surface. According to the invention, the surface 520 and the groove 524 form an L-shaped receptacle (L-slot) in the connecting web 508, into which a support element 528 extending from a surface 526 of the second holding element 510 facing the first holding element 502 engages.
[0086] The first leg 504 has an inner surface 530, which is arranged at a distance from an outer surface 532 of the web 528, so that the cable duct 32 is formed between the support element 528 and the leg 504. Furthermore, the cable duct 32 is delimited by a wall 534 of the web 508 adjacent to the groove 24 and an inner surface 536 of a section 538 of the second holding element 510 extending at a right angle to the support element 528.
[0087] Fig. 6 shows a side view of a second variant 600 of the fastening device according to Fig. 4.
