[0017] The present invention is based on the objective of further developing a wall cabinet mounting of the type mentioned above in such a way that the wall cabinets are held securely and reliably on the wall with simple installation of the wall cabinet mounting and, in addition, the possibility of electrifying the wall cabinets is provided.

[0018] Furthermore, a wall-mounted kitchen system with integrated wall cabinet mounting is to be provided.

[0019] The problem is solved according to the invention, among other things, by the features of claim 1.

[0020] The invention is defined in that the supply channel is a cavity bounded in the state of use by a section of the first retaining element and a section of the second retaining element.

[0021] Because the supply channel is a cavity bounded by a section of the first retaining element and a section of the second retaining element, the advantage is achieved that the individual retaining elements do not have to be designed as closed hollow profiles, which saves material overall.

[0022] In its operational state, a channel in the form of a slot or longitudinal slot is formed between the lower edge of the lower section or base section of the second retaining element and the upper edge of the second leg, allowing the supply line to pass through to the wall. This longitudinal slot makes it possible to insert a supply line, for example, exiting the wall, into the supply channel along its entire length, thus facilitating easy installation. Conversely, the supply line can be routed out of the supply channel at any point along its length, for example, to connect to a wall socket.

[0023] The first retaining element is a profile rail comprising a first leg, a second leg, and a web connecting the legs. The second retaining element is a profile rail comprising a base section attachable to the body and a web-shaped support element extending from the base section, which, in the state of use, interacts with the first retaining element at least by frictional engagement and engages in a recess formed with the web of the first retaining element or interacts with a projection extending from the web by frictional and / or form-fitting engagement, wherein the cavity is bounded by the second leg and a section of the web of the first retaining element and a lower section and a section of the support element of the second retaining element.

[0024] In a particularly simple way, the cavity forming the supply channel is thus limited by the first leg and a section of the web of the first retaining element and a lower section of the base section and a section of the web-shaped support element of the second retaining element.

[0025] In order to easily connect the interior of the kitchen cabinet 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 retaining element.

[0026] The profile rail of the first retaining element has a rectangular, in particular square, outer profile. Due to the rectangular, in particular square, outer profile, the first retaining element can be easily positioned in a receiving channel of the object, such as a wall cabinet or shelf, and fastened therein, e.g., using fasteners such as screws or adhesive.

[0027] Alternatively, the profile rail of the first retaining element can be surrounded on the outside by a plastic encapsulation, such as fiber-reinforced polyethylene, wherein the plastic encapsulation preferably has a rectangular, and in particular a square, outer profile. Wood screws can be used to fasten the first retaining element through the plastic encapsulation, further simplifying assembly. Alternatively, the profile rail encapsulated with the plastic encapsulation can, of course, be glued into the mounting channel of the wall cabinet or shelf.

[0028] To improve stability, the support element extending from the section or base section of the second retaining 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 retaining element, such as a groove or longitudinal slot, or interacts forcefully and / or positively with a projection extending from the web.

[0029] Furthermore, the second leg of the first retaining element is of such a length that, in its operating state, it rests against the body, such as a wall. This also results in improved stability compared to the prior art.

[0030] 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 cable. This allows objects suspended side by side to be electrically coupled to each other via connectors.

[0031] Furthermore, the invention relates to a wall-mounted kitchen system comprising adjacent functional modules in the form of wall cabinets with the features of claim 7.

[0032] The wall-mounted kitchen system is characterized by the fact that the service channel is a cavity bounded, in its operational state, by a section of the first mounting element and a section of the second mounting element. A separate service channel or mounting elements specifically designed as service channels are not required.

[0033] The retaining elements are designed such that when the second retaining element (male part) is inserted into the first retaining element (female part), a cavity is formed which can be used as a cable duct. Electrical cables can be routed through this cable duct, allowing electrical devices inside the cabinet to be connected to a network of power and / or data, such as the internet. These devices can include, for example, lights, sensors, or actuators. Motion sensors or cameras are conceivable as sensors, enabling the monitoring of the cabinet's interior. Actuators can be motors for opening and closing doors or drawers. LED lights or panels in the cabinet doors that can be illuminated or dimmed (from transparent to opaque) can be used as lights. Sensors can also be used to measure the weight of a cabinet or shelf, for example, to...The ability to determine the consumption of a product or the quantity of certain goods is significantly simplified by the cable duct according to the invention. This allows for the integration of cabinets and their contents, as well as appliances such as microwaves, refrigerators, sinks, and / or stoves, into a "smart home" environment.

[0034] A particularly preferred embodiment is characterized in that the first retaining element is a profile rail or a section thereof, comprising a first leg, a second leg and a web connecting the legs, and that the second retaining element is a profile rail or a section thereof, comprising a section attachable to the body and a support element extending from the section, which interacts with the first retaining element in the state of use at least by frictional engagement, wherein the cavity is bounded by the second leg and a section of the web of the first retaining element and a lower section of the base section and a section of the support element of the second retaining element.

[0035] Furthermore, the wall-mounted kitchen system is characterized by the fact that the supply channel terminates at each end with a connector that is connected to the power supply line, with adjacent functional modules being connected to each other via these connectors. The supply channel for the electrical connection is designed to be compatible with a plug-in system, allowing for easy connection of the various functional modules, such as kitchen cabinets.

[0036] To supply the interior of the functional modules with, for example, electrical energy, a feedthrough is provided in the second leg or the lower section of the web of the first retaining element, through which the supply line is routed into the interior of the functional module. This feedthrough allows, for example, an electrical cable to be routed into the interior of the functional module to supply electrical devices such as lights, fans, sensors, electric refrigerators, microwaves, extractor hoods, steam cookers, ovens, and stoves.

[0037] To allow for flexible decision-making at any time along the entire length of the service duct regarding the placement of electrical cables within the wall, a longitudinal slot or gap is provided between the lower edge of the base section of the second retaining element and the upper edge of the second leg of the first retaining element to allow the service cable to pass through the wall. This longitudinal slot or gap also offers the advantage of integrating multiple wall connections along the length of the service duct or allowing them to exit the duct.

[0038] Another alternative design involves a wall-mounted kitchen system comprising at least one functional module, which has a first holding element and a second holding element, such as a wall rail, which is attached to a wall and on which the at least one functional module with the first holding element is suspended.

[0039] Such a wall-mounted kitchen system differs from the prior art in that the first retaining element is a profile rail or a section thereof, comprising a first leg, a second leg and a web connecting the legs, and that the second retaining element is a profile rail or a section thereof, comprising a section attachable to the wall and a support element extending from the section, wherein an upper part of the section of the second retaining element has a recess or a slope pointing away from the body, into which, in the state of use, a projection of an L-shaped end of the first leg engages in a form-fit and force-fit manner, and wherein, in the state of use, the support element extending from the section interacts with the first retaining element at least in a force-fit manner.

[0040] This design is particularly suitable for wall-mounting functional modules in the form of kitchen cabinets, especially wall-mounted kitchen cabinets for housing refrigerators, dishwashers, stoves, etc. The special design of the first and second mounting elements allows for the secure and easy installation of very heavy functional modules. Furthermore, the special design of the profile rail takes into account that the functional modules housing the aforementioned appliances have a depth of 60–80 cm, typically at least 65 cm, and thus exert a high torque on the mounting elements.

[0041] Preferably, the first retaining element is arranged in a receiving channel, preferably formed on the wall side at an upper edge of the functional module.

[0042] It is provided that the profile rail of the first retaining element has a rectangular, in particular square, outer profile.

[0043] For easy assembly of the profile rail, it is provided that the profile rail of the first retaining element is surrounded on the outside by a plastic edging, such as fiber-reinforced polyethylene, as if overmolded, wherein the plastic edging preferably has a rectangular, in particular square, outer profile.

[0044] The plastic encasing offers 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.

[0045] To further stabilize the fastening element, it is provided that the support element extending from the section of the second retaining 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 retaining element, such as a groove or longitudinal slot, or interacts forcefully and / or positively with a projection extending from the web.

[0046] In other words, an "L-slot" is formed, i.e., an L-shaped projection of the second retaining element (male part) that provides an additional support. In total, three contact points or surfaces are provided between the second retaining element and the first retaining element (male and female parts): firstly, an inclined section and a substantially vertical section in the upper area, and secondly, the L-slot in the middle area.

[0047] A further constructive improvement results from the fact that the second leg of the first retaining element has a length such that it rests against the body, such as a wall, in the state of use.

[0048] These designs differ from existing versions in that they are more robust and can support large and far-reaching loads. For example, the first support element can have dimensions of, say, 85 mm in depth and 155 mm in height. These "heavy-duty" versions are particularly suitable for mounting far-reaching loads, such as kitchen cabinets, i.e., wall cabinets and base cabinets.

[0049] Compared to known designs, the advantage is that warping or bending is excluded, thus ensuring faster and safer assembly.

[0050] Preferably, the first retaining element (mother part) has a first leg which, in its lower wall-side part, is designed as a support against the wall.

[0051] It is also possible to glue the first and second retaining elements together. This means that a tensioning element for both bottom-side and top-side tensioning is not strictly necessary.

[0052] However, tensioning with a tensioning element is the preferred embodiment so that the kitchen cabinets can also be dismantled without causing damage to the wall.

[0053] The second retaining element can be injected with or partially overmolded in a fiber-reinforced polyurethane 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.

[0054] Another preferred embodiment is characterized by the fact that a metal plate, designed as a spacer, is arranged in a lower leg of the first retaining element. The metal plate is operatively connected to a screw, whereby turning the screw causes a horizontal displacement of the plate such that, for example, when the screw is turned clockwise, the plate moves out of the leg, and when the screw is turned counterclockwise, it moves into the first retaining element. This allows for alignment of the "Kitchen Bracket" fastening device even when the wall has irregularities.

[0055] Furthermore, a method for suspending functional modules of a wall-mounted kitchen system is described, wherein functional modules with a first holding element are preferably suspended side by side on a second holding element, such as a wall rail.

[0056] It is provided that a profile rail or a section thereof is used as the first retaining element, comprising a first leg, a second leg and a web connecting the legs, and that a profile rail or a section thereof is used as the second retaining element, comprising a section attachable to the body and a support element extending from the section, wherein an upper part of the section of the second retaining element has a recess or a slope pointing away from the body into which, in the state of use, a projection of an L-shaped end of the first leg is engaged in a form-fit and force-fit manner, and wherein, in the state of use, the support element extending from the section interacts with the first retaining element at least force-fit.

[0057] Further details, advantages and features of the invention will become apparent not only from the claims and the features to be derived therefrom - individually and / or in combination - but also from the following description of preferred embodiments to be derived from the drawings.

[0058] They show: Fig. 1 a side view of an arrangement of objects, such as kitchen base cabinets or kitchen wall cabinets, each attached to a wall by means of a fastening device, Fig. 2 a side view of a body with a receiving channel for the fastening device, Fig. 3 a side view of a first embodiment of the fastening device according to Fig. 1 In detail, Fig. 4 shows a side view of a second embodiment of a fastening device, Fig. 5 shows a side view of a first non-inventive variant of the second embodiment according to Fig. 4 , Fig. 6 a side view of a second variant of the second design according to Fig. 4 , Fig. 7 a side view of a third variant of the second design according to Fig. 4 Fig. 8 shows a side view of a third embodiment of a fastening device, Fig. 9 shows a side view of a first variant of a third embodiment according to Fig. 8 , Fig.10 a side view of a fourth embodiment a fastening device and Fig. 11 a perspective view of a wall-hung kitchen system.

[0059] Fig. 1 Figure 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, which are suspended, in particular floating, in a suspended manner. For example, the kitchen base cabinet 10 in the illustrated example is suspended from the wall 16 at a distance from a floor 18. The objects can be any type of item, such as shelves, pictures, lamps, etc.

[0060] The fastening device 14 comprises a first retaining element 20, which is arranged and fastened to the object 10, 12, and a second retaining element 22, which is arranged and fastened to the wall.

[0061] The first retaining element 20 is arranged in and fastened in a receiving channel 24 formed in the object 10, 12, preferably at an upper edge. Fastening can be effected by means of fasteners 26, such as screws, or alternatively by clamping or gluing.

[0062] The first retaining element 20 and the second retaining element 22 are designed as longitudinally extending profile strips and have sections 28, 30 with at least partially corresponding cross-sections which can be brought into at least partial positive engagement with each other.

[0063] It is provided that a longitudinally extending cavity, designated as a cable duct 32, is formed in the first retaining element 20, the second retaining element 22, and / or between the first and second retaining elements 20, 22. At least one opening 34 extends from the cable duct 32 into an interior space 36 of the cabinet 10, 12, through which an electrical cable contained in the cable duct 32 can be routed for the operation of an electrical device 38, such as a light, sensor, camera, or other electrical device. Furthermore, at least one opening 40 extends from the cable duct 32 towards the wall 16, through which electrical cables exiting the wall 16 can be inserted into the cable duct 32.

[0064] In the illustrated embodiment, the kitchen cabinet 10, 12 comprises a body 42 with a top surface 44, in the wall-side end of which the receiving channel 24 is arranged. In the illustrated embodiment, the top surface 44 of the body 42 is covered with a worktop 46, which terminates at the wall side with a plinth 48.

[0065] Fig. 2 The side view shows the pre-worked body 42 for the kitchen cabinet 10, 12 with the receiving channel 24 for the fastening device 14.

[0066] Fig. 3 Figure 1 shows a side view of a first embodiment of the fastening device 14. In the illustrated embodiment, the first retaining element 20 consists of a preferably metallic profile rail 50, which is surrounded on the outside by a plastic edging 52, for example, fiber-reinforced polyethylene. The plastic edging 52 can be applied by a co-extrusion process. The plastic edging 52 preferably has a rectangular cross-section on its outer surface, which is adapted to an inner cross-section of the receiving channel 24. The plastic edging 52 allows for easy fastening of the first retaining element 20 in the receiving channel 24 by means of, for example, wood screws. To fasten the first retaining element 20, the fastening elements 26, such as wood screws, are screwed through the wooden wall elements of the body 44, which define the receiving channel 24, into the plastic edging 52.

[0067] 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.

[0068] To secure the first retaining element 20, a fastening element 59, such as a grub screw, can be provided, which passes through the upper wooden panel element 44 of the body 42, the plastic edging 52, and the first leg 56, connecting these elements together. After securing the first retaining element 20, the cover or worktop 46 can be mounted.

[0069] The C-shaped first retaining element 20 has a longitudinally extending opening 60 on its wall side, by means of which the first retaining element 20 can be hooked into the second retaining element 22. This allows the first and second retaining elements 20, 22 to be brought into at least partial positive engagement with each other.

[0070] A projection 64 extends from a surface 62 of the profile rail 50 facing away from the opening 60. This projection is enclosed, as if overmolded, by the plastic edging 64. This ensures a good connection between the profile rail and the plastic edging, as well as high stability.

[0071] 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. A recess 68 facing the wall is provided in an upper part of the section 66, 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.

[0072] A web 76 extends from a surface 74 of section 66 facing the first retaining element 20, which runs essentially parallel to the surface of section 66 abutting the wall. This web 76 rests against an inner wall 78 of the profile rail 50 and is sloped downwards 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.

[0073] The cable or supply duct 32 is a cavity in its operating state bounded by a section, such as the inner wall 80, of the first retaining element 50 and a section of the second retaining element 22.

[0074] Fig. 4 Figure 1 shows an alternative embodiment of a fastening device 82, which is arranged in the receiving channel 24 of the body 42 of the cabinet 10, 14. The fastening device 82 comprises a first retaining element 84 and a second retaining element 86, each designed in the form of a preferably metallic profile rail. The first retaining element 84 has a substantially rectangular outer profile, which is received directly in the receiving channel 24 and fixed therein by means of fastening elements 88, such as screws. The screws 88 can be wood screws or metric screws that engage in a thread or threaded sleeve 90 arranged in the profile rail. The first retaining element 84 is C-shaped and comprises a first, lower leg 92 and a second, upper leg 94, which is L-shaped.

[0075] The second retaining element 86 is attached to the wall 16 by means of fasteners 96, such as screws. A recess 10 is formed in the wall-side of an upper section 98 of the second retaining element 86 to create 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 positive locking. This creates a force-fit and form-fit connection.

[0076] Additionally, a screw connection 103 can be provided. The screw 103 passes through the wooden panel element 44 of the body 42, the second leg 94 of the first retaining element 86, and engages in the section 100 of the second retaining element to further secure it. The screw 103 can engage in a thread or threaded sleeve 104 that is located in one or both of the profiles 84, 86.

[0077] Furthermore, it is provided that 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 fixed 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.

[0078] In this embodiment, the cable duct 32 between the first retaining element 84 and the second retaining element 86 is designed as a cavity. This cavity is bounded 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.

[0079] Fig. 5 shows in side view a first non-inventive 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 each other via a web 508. The 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 engaged in the first retaining element 502.

[0080] A surface 512 of the second leg 506 facing the second retaining element 510 has a cross-section that corresponds at least partially to a cross-section of a surface 514 of the second retaining element 510. The corresponding surfaces 512, 514 comprise a straight section 516 that runs parallel or substantially parallel to the first leg 504, and a surface 518 that rises at an angle of preferably 45° towards the connecting web 508 and transitions into a surface 520 that runs parallel to the first leg 504.

[0081] An inner surface 522 of the connecting web 508 extends perpendicular to the surface 520. A longitudinal groove 524 is formed in this surface. The surface 520 and the groove 524 form an L-shaped recess (L-slot) in the connecting web 508 into which a support element 528 extends from a surface 526 of the second retaining element 510 facing the first retaining element 502.

[0082] The first leg 504 has an inner surface 530, which is arranged at a distance from an outer surface 532 of the web 528, such that the cable duct 32 is formed between the support element 528 and the leg 504. Furthermore, the cable duct 32 is bounded by a wall 534 of the web 508 adjacent to the groove 24 and by an inner surface 536 of a section 538 of the second retaining element 510 extending perpendicular to the support element 528.

[0083] Fig. 6 shows side view of a second variant 600 of the fastening device according to Fig. 4 The fastening device 600 comprises a first retaining element 602 in the form of a profile rail and a second retaining element 604 in the form of a profile rail. The first retaining element 602 comprises a first leg 605, a second leg 606, and a web 608 connecting the legs. The second retaining element is L-shaped, with an inner surface 610 of the first leg 606 having a cross-section that corresponds to an outer surface 612 of the second retaining element 604, such that the retaining elements can be brought into at least partial positive engagement with one another.
