[0001] The invention relates to a built-in system comprising a built-in cooking appliance and a fastening device of the type mentioned in the preamble of claim 1.

[0002] Such built-in systems are already known from the prior art. The known built-in systems comprise a built-in oven for installation in a recess of a piece of furniture and at least one fastening device for mechanically fastening the built-in oven to the furniture, wherein the built-in oven has a housing, an oven compartment arranged in the housing and closable by means of an oven door of the built-in oven, a front frame formed on or connected to the housing, and at least one first fastening part of the fastening device attached to the front frame for fastening the built-in oven to the furniture, and wherein the first fastening part of the fastening device interacts with a second fastening part of the fastening device in such a way that, in an installed state of the built-in system, the built-in oven is arranged in the recess and is fastened to the furniture by means of the fastening device.In many cases, the first fastening part is designed as a tab with a through hole and the second fastening part as a screw, whereby the built-in cooking appliance inserted into the installation niche is screwed to the furniture having the installation niche by means of the screw and the tab.

[0003] The invention therefore addresses the problem of improving a built-in system with a built-in cooking appliance and a fastening device.

[0004] According to the invention, this problem is solved by an installation system with the features of claim 1, characterized in that the fastening device is designed as a snap-fit ​​device, wherein the first fastening part, designed as the first snap-fit ​​element, and the second fastening part, designed as the second snap-fit ​​element and pre-attached to the furniture, are designed and arranged in such a way that, when the built-in oven is moved in an installation direction to transfer the installation system into its installed state, the first snap-fit ​​element engages with the second snap-fit ​​element in such a way that the built-in oven is held on the furniture along the installation direction in the installed state of the installation system. Advantageous embodiments and further developments of the invention are described in the following dependent claims.

[0005] The advantage achievable with the invention lies particularly in the improved installation system comprising a built-in oven and a mounting device. Due to the inventive design of the installation system, the installation of the built-in oven in a recess of a piece of furniture, for example, a kitchen cabinet, is significantly simplified. An installer simply needs to slide the built-in oven into the recess, i.e., move it only in the installation direction. The two locking elements engage with a snap-lock mechanism, and the built-in oven is held against the furniture along the installation direction, both in and out of the direction. Accordingly, installation can generally be carried out without tools.

[0006] In principle, the built-in system according to the invention can be freely selected within wide suitable limits with regard to type, function, material, arrangement of components, and dimensions. For example, the invention can be advantageously used in both household appliances and commercial appliances, i.e., built-in cooking appliances for professional use. Furthermore, the built-in cooking appliance according to the invention can be designed, for example, as a conventional oven, a steam oven, a microwave oven, or a combination appliance with a plurality of different heating methods.

[0007] A particularly advantageous embodiment of the installation system according to the invention provides that the first locking element has a pin and the second locking element is designed as a snap fastener corresponding to the pin, or that the first locking element is designed as a snap fastener and the second locking element has a pin corresponding to the snap fastener. In this way, the two locking elements, and thus the locking device, are designed in a particularly simple, robust, and reliable manner from a structural and manufacturing perspective.

[0008] An advantageous further development of the aforementioned embodiment of the installation system provides that the pin and the catch are designed to be coordinated such that the pin, which is connected to the catch in the installed state of the installation system, can be disengaged by means of a disassembly force acting against the direction of assembly. This not only simplifies the assembly of the installation system according to the invention, i.e., simplifies the transfer of the installation system according to the invention into the installed state, but also facilitates the transfer of the installation system from the installed state to a disassembled state, i.e., a transfer of the installation system according to the invention into the disassembled state.

[0009] A particularly advantageous further development of the two latter embodiments of the installation system according to the invention provides that the pin and the catch are designed and arranged to compensate for tolerances, preferably that the pin and the catch are designed to compensate for tolerances perpendicular to the mounting direction, and especially preferably that the catch is over-dimensioned along a vertical axis compared to the pin such that the pin is securely held in the catch despite tolerances along the vertical axis. In this way, it is ensured that the installation system according to the invention functions properly even with existing component and assembly tolerances. This applies particularly to the preferred embodiment. Furthermore, the particularly preferred embodiment offers a very simple implementation of such tolerance compensation in terms of design and manufacturing.

[0010] A further advantageous embodiment of the installation system according to the invention provides that the first locking element is designed as a plastic part, preferably that the first locking element is detachably attached to the front frame, and particularly preferably that the first locking element is attached to the front frame by means of snap-fit ​​connections. This enables, on the one hand, cost-effective and flexible manufacturing of the first locking element. On the other hand, this results in an advantageous material pairing for front frames made of metal, for example, stainless steel. The preferred embodiment also has the advantage that the first locking element can not only be removed from the front frame, but that this is also possible in a very simple manner. The aforementioned advantages apply in particular to the especially preferred embodiment of this embodiment, which enables both simple assembly and simple disassembly of the first locking element.

[0011] An advantageous embodiment of the installation system according to any one of claims 2 to 5 provides that, in a top view, the pin is formed at a free end as an acute-angled wedge, preferably that the acute-angled wedge transitions in this top view towards a root of the pin into a constriction on both sides of the pin, this transition being formed as an obtuse-angled wedge, and the snap fastener is designed correspondingly to this pin. In this way, the installation system can be moved into the installed state with relatively little effort. The preferred embodiment of this embodiment further ensures that, despite the aforementioned simplification in moving the system into the installed state, the pin is held with a sufficiently high holding force by means of the snap fastener in the installed state.The pins and catches are designed to be coordinated in such a way that, on the one hand, the installation system can be easily transferred into the installed state, and on the other hand, the built-in appliance is securely held in place on the furniture in the installed state.

[0012] An advantageous embodiment of the installation system according to any one of claims 2 to 6 provides that the catch is designed as a spring with two lateral spring arms, wherein the spring arms engage with the pin in a latching manner. Preferably, the two lateral spring arms are arranged on a central support plate of the catch for attaching the catch to the furniture or the front frame. Particularly preferably, the catch is designed as a one-piece sheet metal part. This results in a particularly simple design and manufacturing process for the catch. The preferred embodiment of this embodiment further has the advantage that the catch has, on the one hand, a central section for attachment to the furniture and, on the other hand, a separate section for the force-transmitting engagement of the catch with the pin.Accordingly, the aforementioned sections can each be designed to suit their respective function. Furthermore, the particularly preferred embodiment of this further development provides a particularly simple and robust implementation of the snap fastener.

[0013] An advantageous further development of the latter embodiment of the installation system according to the invention provides that markings are arranged on the support plate to facilitate the attachment of the snap fastener to the furniture. Preferably, a snap fastener for holding a pin is provided on each side of the built-in oven on a side panel of the furniture in the installed state of the installation system. The markings are arranged such that central installation of the built-in oven between the two side panels of the furniture is supported. Particularly preferably, the markings are arranged to accommodate side panel wall thicknesses of 16 mm and 19 mm. In this way, the attachment of the snap fastener to the furniture is significantly simplified with minimal additional effort.When attaching the catch, the installer can align furniture edges or similar features with the corresponding markings to align it with the furniture. These markings can be, for example, indentations or similar features on the catch. The preferred embodiment is particularly advantageous because it also allows for spatial alignment of the built-in oven relative to the furniture, namely lateral centering of the built-in oven within the installation niche. The particularly preferred embodiment has the additional advantage that the catch can be used for furniture with different side panel thicknesses, namely 16 mm, 19 mm, and 20 mm.This is because the latch has markings for side panel wall thicknesses of 16 mm and 19 mm, and the outer edges of the latch, for example of its mounting plate, provide further markings for side panel wall thicknesses of 20 mm.

[0014] A particularly advantageous embodiment of the installation system according to the invention provides that the installation system is designed such that the locking device is completely invisible to a user of the built-in oven, even when the oven door is open. Preferably, the locking element associated with the front frame is attached to the front frame in such a way that this locking element is located behind a front panel of the built-in oven in the user's line of sight. This significantly improves the overall visual appearance of the installation system according to the invention, and in particular of the built-in oven. This is especially true for the preferred embodiment of this embodiment. This advantage is particularly significant for very high-quality built-in ovens, as these are designed to meet the highest standards, including those related to design.For example, a stainless steel front frame is showcased much more effectively as a result. The aforementioned front panel can, for instance, be designed as a control panel, as is customary. Particularly in high-quality built-in ovens, the front panel forms a cohesive and aesthetically pleasing unit with the rest of the oven's front panel. According to this further development, the locking mechanism does not detract from this overall appearance.

[0015] Furthermore, another advantageous embodiment of the installation system according to the invention provides that the installation system is designed to allow for tool-free transfer of the installation system into the installed state and for tool-free transfer of the installation system into a removed state. In this way, simple and therefore time-saving installation and removal of the built-in oven are made possible.

[0016] An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows Fig. 1a an embodiment of the installation system according to the invention in a disassembled state, in a frontal view, Fig. 1b the embodiment analogous to Fig. 1a, in an installed state, Fig. 2 the first locking part of the embodiment with the pin in a detailed view, in a top view, Fig. 3 the snap fastener of the embodiment in a perspective view, Fig. 4 the latch analogous to Fig. 3, in a top view and Fig. 5 the locking device of the embodiment in a top view, with the pin and the snap in engagement.

[0017] In the Fig. Figures 1a to 5 are an exemplary embodiment of the installation system according to the invention.

[0018] The built-in system 2 comprises a built-in oven 4, designed as a household oven, for installation in a built-in niche 6 of a kitchen unit 8, and a total of two fastening devices for mechanically fastening the built-in oven 4 to the unit 8. The built-in oven 4 includes a housing 10, a cooking chamber 14 arranged in the housing 10 and closable by means of a cooking chamber door 12 of the built-in oven 4, a stainless steel front frame 16 formed on or connected to the housing 10, and a total of two first fastening parts of the fastening device for fastening the built-in oven 4 to the unit 8, attached to the front frame 16, wherein the first fastening part of the fastening device interacts with a second fastening part of the fastening device such that in a Fig. In the installation state of the built-in system 2 shown in Figure 1b, the built-in oven 4 is arranged in the installation niche 6 and is attached to the furniture 8 by means of the fastening device. The oven door 12 is in the Fig. 1a and Fig. 1b each shown open, i.e., in an open position.

[0019] According to the invention, the fastening device is designed as a locking device 18, wherein the first fastening part, designed as the first locking element 20, and the second fastening part, designed as the second locking element and pre-attached to the furniture 8, are designed and arranged in such a way that when the built-in oven 4 is moved in an installation direction to transfer the installation system 2 into its installed state, the first locking element 20 engages with the second locking element in such a way that the built-in oven 4 is held on the furniture 8 along the installation direction in the installed state of the installation system 2. The two locking devices 18 are designed analogously to each other, so that the further textual descriptions and graphic representations relating to one of the locking devices 18 apply analogously to the locking device 18 not described in text or shown in the drawings.

[0020] The first locking element 20 has a pin 22, and the second locking element is designed as a catch 24 corresponding to the pin 22 and pre-attached to the furniture 8. The pin 22 and the catch 24 are designed to be compatible such that the pin 22, which is connected to the catch 24 in the installed state of the installation system 2, can be disengaged by a disassembly force acting against the direction of assembly. Accordingly, the built-in oven 4 can also be disengaged from the installed state in the Fig. The installation system 2 can be converted to the installation state shown in Figure 1a. In the present embodiment, the installation system 2 is designed to allow for tool-free conversion of the installation system 2 into the installation state as well as tool-free conversion of the installation system 2 into the removal state. The pin 22 and the catch 24 are designed and arranged to compensate for tolerances, with the pin 22 and the catch 24 being designed to compensate for tolerances perpendicular to the installation direction, namely such that the catch 24 is over-dimensioned along a vertical axis compared to the pin 22 in such a way that the pin 22 is securely held in the catch 24 despite tolerances along the vertical axis. The installation direction runs in the Fig. 1a perpendicularly into the image plane and in the Fig. 5 from bottom to top. The vertical axis runs in the Fig. 1a and Fig. 1b in the respective image plane from bottom to top and in the Fig. 5 perpendicular to the image plane. Of course, embodiments of the invention are also conceivable in which the first locking element is designed as a snap and the second locking element has a pin corresponding to the snap.

[0021] In the present embodiment, the first locking element 20 is designed as a plastic part, and is detachably attached to the front frame 16 by means of locking connections (not shown). For this purpose, the first locking element 20 has locking lugs (not shown), and the front frame 16 has corresponding locking openings (also not shown). However, the design of the aforementioned locking connections is not limited to this. The pin 22, which rises from a base plate of the first locking element 20 for attaching the first locking element 20 to the front frame 16, is located in a Fig. In the top view shown in Figure 2, a wedge is formed at one free end of the pin 22 as an acute-angled wedge. In this top view, the acute-angled wedge transitions towards the root of the pin 22, i.e., towards the base plate, into a constriction 26 on both sides of the pin 22, this transition being formed as an obtuse-angled wedge, and the catch 24 is formed correspondingly to this pin 22. See Figure 2 for further details. Fig. 2, Fig. 4 and Fig. 5 in a summary.

[0022] The catch 24 is designed here as a spring with two lateral spring arms, the spring arms engaging with the pin 22 in a detent-like manner. See the Fig. 5. The two lateral spring arms are arranged on a central support plate 28 of the catch 24 for attaching the catch to the furniture 8, the catch 24 being designed as a one-piece sheet metal part in the present embodiment. Markings 30, 32 are arranged on the support plate 28 to assist in attaching the catch 24 to the furniture 8. Each catch 24 is provided on one side of the built-in appliance 4 on a side panel of the furniture 8 for holding a pin 22 in the installed state of the installation system 2, the markings 30, 32 being arranged such that the built-in appliance 4 is supported in being installed centrally between the two side panels of the furniture 8. The markings 30 correspond to a side panel wall thickness of 16 mm for the furniture 8 and the markings 32 correspond to a side panel wall thickness of 19 mm for the furniture 8.The outer lateral edges of the support plate 28 are spaced so far apart that they correspond to a side panel wall thickness of the furniture 8 of 20 mm. See the [reference]. Fig. 3.

[0023] In the present embodiment, the installation system 2 is further designed such that the locking device 18 remains in the installed state of the installation system 2 even when the oven door 12 of the built-in oven 4 is open, as shown in the Fig. 1a and Fig. As shown in Figure 1b, the first locking element 20 is completely invisible to a user of the built-in oven 4 who is not shown. For this purpose, the first locking element 20 associated with the front frame 16 is attached to the front frame 16 in such a way that, in the user's line of sight, this first locking element 20 is located behind a front panel 34 of the built-in oven 4. The front panel 34 is designed here as a control panel of the built-in oven 4.

[0024] The following describes the functioning of the installation system according to the invention, as illustrated in the present embodiment: Fig. 1a to 5 explained.

[0025] Initially, the installation system 2 is located in the Fig. Figure 1a shows the completed state. The two latches 24 are screwed to one of the two side panels of the furniture 8 by means of screws (not shown) and through holes in the support plate 28. The two outer edges of the respective support plate 28 serve as markings for aligning the respective latch 24 on the corresponding side panel of the furniture 8.

[0026] For the purpose of transferring the installation system 2 from its disassembled state to its installed state in the Fig. In the installation state shown in Figure 1b, the installer grasps the built-in oven 4 and pushes it into the installation niche 6 of the cabinet 8 in the direction of installation. As soon as the two pins 22 of the first locking parts 20 mounted on the front frame 16 engage with the corresponding catch 24, the pins 22 lock into the catches 24, so that the built-in oven 4 is held against the cabinet 8 in the direction of installation and against the direction of installation. Furthermore, the built-in oven 4 is also aligned relative to the cabinet 8, namely in the plane of the image. Fig.1b in the horizontal axis. The engagement of the respective pin 22 in the corresponding catch 24 is significantly simplified by the free end of the pin 22, which is designed as an acute-angled wedge, and by the leg-like, open spring arms of the catch 24. After the pin 22 has been moved far enough in the assembly direction, the two spring arms of the catch 24 engage behind the pin 22 in such a way that the pin 22 and the catch 24 can only be disengaged again with a greater force than when moving the unit into its installed state. The built-in oven 4 is in its installed state and is releasably fixed along the assembly direction by means of the pins 22 and the catch 24.The overall visual impression of the built-in system 2, in particular the built-in oven 4, is not impaired by the locking device 18, namely the first locking elements 20 with the pins 22 attached to the front frame 16 and the catches 24 attached to the side panels of the cabinet 8. Instead, the desired aesthetic of the front of the built-in oven 4 with the front frame 16 and the front panel 34 can be fully realized.

[0027] Should it become necessary to remove the built-in oven 4 from the installation niche 6, i.e., to return the built-in oven 4 from its installed state to its removed state, this can be done without excessive force and without tools. See the above instructions, but in reverse order.

[0028] Due to the inventive design of the installation system 2, the installation of the built-in oven 4 into the installation niche 6 of the furniture 8 is significantly simplified. The installer simply needs to slide the built-in oven 4 into the installation niche 6, i.e., move it only in the installation direction. The aforementioned locking elements engage with a snap-lock mechanism, and the built-in oven 4 is held against the furniture 8 along the installation direction, both in and against it. Installation can be carried out without tools.

[0029] The invention is not limited to the present embodiment. See the relevant explanations in the introductory section of the description and the descriptions of optional and alternative embodiments in the specific section of the description.
