A furniture panel assembled from two partial panels with a recess extending from a side surface and end face, accommodating a mounting element that allows the movement fitting to be completely inserted, with means for fastening and easy removal, such as adhesive bonding and guide webs, ensuring minimal protrusion and maintaining surface integrity.
The solution enables the movement fitting to be fully recessed within the panel, maintaining the furniture's aesthetic and functional integrity, with the ability to be easily replaced without compromising the panel's strength or stability.
Description
[0001] The invention relates to a method for integrating a mounting element for a motion fitting into a furniture panel. The invention further relates to a furniture panel with an integrated mounting element and a motion fitting for movable furniture parts inserted therein, wherein the mounting element has at least one side wall and is inserted into a recess in the furniture panel. The invention further relates to a furniture carcass or a piece of furniture with such a furniture panel.
[0002] Furniture bodies are typically made of furniture panels made from wood or a wood-based material, such as particleboard or medium-density or high-density fiberboard (MDF, HDF). Connecting fittings, movement fittings, or other functional fittings, which are collectively referred to as fittings in this context, are used to connect the furniture panels to one another or to articulate movable furniture parts such as doors or flaps. Fittings are generally made of plastic and / or metal materials. Larger fittings, in particular, are typically placed on the furniture panels and screwed to them.They then protrude into the interior of the furniture body, making them invisible when the door or flap is closed. However, they impair the appearance of the furniture body when it is open and reduce the usable interior volume of the furniture body. For smaller fittings, recessing into a hole or recess is also known, for example, from WO 2016 / 174071 A1. According to this document, the fitting is not attached directly to the furniture panel, but rather inserted into a mounting element that is mounted in a recess in the furniture panel.
[0003] The publication DE 20 2014 105 730 U1 describes a furniture panel in which an insert part is arranged in a material recess from one side of the furniture panel, which insert part can accommodate a movement fitting. The material recess can be provided with undercut sections in order to fix the insert part at least in a direction perpendicular to the surface of the furniture panel. Further details on the attachment of the insert part to the furniture panel or of the movement fitting to the insert part are not described. The advantage of the arrangement of the insert part in the recess in the furniture panel is that the inserted movement fitting is positioned completely or partially recessed relative to the surface of the furniture panel, whereby it protrudes only slightly or not at all into the interior of a furniture body.However, the movement fitting is still visible on at least one side of the furniture panel and prevents the side surface of the furniture panel from being homogeneous visually and in terms of material and texture.
[0004] The publication WO 2009 / 059896 A1 describes a connecting fitting for lightweight panels. It consists of two identical halves, each of which is glued into one of the panels to be connected. Each half of the fitting has a protruding clamp that engages with the other half of the fitting to connect the two panels. The connecting fitting is inserted into a recess in the respective panel from one side, with the clamps engaging into the other half of the fitting through openings in the end face. From one side of the connected panels, the connecting fitting is therefore not visible and connects the panels in a concealed manner, which is sufficient, for example, for connecting two table or worktops. From the opposite side, however, the connecting fitting is also visible. Other relevant documents are FR 3 023 331 A1 or CN 102 224 315 A.
[0005] From publication WO 2017 / 029199 A1, a cabinet carcass with an upward-opening flap is known, in which a flap fitting is screwed onto the inside of a side panel of the carcass in the usual manner. The fitting is then covered by an additional cover panel arranged parallel to the side panel inside the carcass and extending over the entire surface of the side panel. This provides a continuous and therefore homogeneous wall surface facing the interior of the carcass. However, the manufacturing effort for such a carcass with a kind of double side panel is comparatively high, and the carcass has a greater wall thickness than a conventional furniture panel. Furthermore, replacing the fitting is only possible with considerable effort, requiring the removal of the inner cover panel.
[0006] In the subsequently published patent application DE 10 2017 104 170 A1, the applicant describes furniture panels in which a cassette-shaped fitting is integrated in such a way that the side surfaces of the furniture panel are essentially flat. For this purpose, a furniture panel is assembled from two sub-panels separated along a central plane, with recesses of mirror-image contours being incorporated into both sub-panels, for example, milled into them. When the furniture panel is assembled, these recesses form a cavity into which the fitting is inserted, for example, glued. None of the side surfaces of the furniture panel are affected by the fitting with regard to their appearance, surface texture, and / or material.
[0007] It is an object of the present invention to provide a furniture panel with an integrated mounting element in which none of the side surfaces of the furniture panel is influenced by the movement fitting with regard to its appearance, its surface quality and / or the material, and in which the movement fitting can nevertheless be easily replaced.
[0008] This object is achieved by a furniture panel and a method for producing a furniture panel having the features of the respective independent claim. Advantageous embodiments and further developments are the subject of the dependent claims.
[0009] A furniture panel according to the invention of the type mentioned at the outset is characterized in that the furniture panel is assembled from at least two partial panels, and the recess in at least one partial panel extends from a side surface of the partial panel and at least one end face of the furniture panel, and the recess is directed towards the at least one other partial panel, wherein at least the side wall of the mounting element is connected to a counter surface of the recess by a force-fit or material-fit connection, and the mounting element has means for attaching the motion fitting. The motion fitting can be inserted essentially completely into the furniture panel, wherein movable parts of the motion fitting can be extended from an end face of the furniture panel.
[0010] The mounting element allows the movement fitting to be inserted through an opening in the front of the furniture panel and removed again if necessary. The mounting element is already incorporated into the furniture panel during manufacture. By assembling the furniture panel from two partial panels, the recess that accommodates the mounting element can be made over a large area from one side of the partial panel. This creates a recess that can also accommodate a correspondingly large mounting element for a large movement fitting, e.g., a flap fitting. The mounting element can, for example, be cassette-shaped and have two opposing side walls.
[0011] The fact that the movement fitting can be inserted "essentially completely" into the furniture panel is to be understood in such a way that any slight protrusion of the movement fitting relative to the front of the furniture panel is so small that it does not impair the closing of a furniture body or piece of furniture by the movable furniture part (door, flap, front, etc.). The possible protrusion is preferably less than approximately 1-3 millimeters (mm). A protrusion of this magnitude is generally within the existing gaps between the furniture body and the movable furniture part or can be compensated for by a narrow-side coating (e.g., an edge band). It is also understood that the fitting is (only) located within the furniture panel in its retracted state, in which the movable furniture part closes the furniture body. When the furniture part is opened, the extending components of the movement fitting, e.g.a lever mechanism, above the front.
[0012] In an advantageous embodiment of the furniture panel, the recess is incorporated into one of the panels, while the other panel is flat and without a recess. Alternatively, both panels have (partial) recesses which, when the panels are joined, together form the recess. The partial recesses can be mirror-symmetrical, but this is not required.
[0013] The recess(s) can be (subsequently) introduced into the partial plate(s), preferably by milling or embossing. The partial plates can thus initially be manufactured conventionally, e.g., from wood or a wood-based composite material, without the recess, and the recess can then be created. This can preferably be done from the side surface. Alternatively, the recess can be created together with the partial plate in a primary forming process, e.g., in a foaming or casting process.
[0014] In another advantageous embodiment of the furniture panel, the recess has a constant depth across its surface. This is a particularly easy-to-produce recess shape, especially when milling the (partial) recess. However, other shapes are also possible, such as a recess with varying depths, where the recess is deeper in the area of the operating mechanism, where moving hardware elements like levers or the like are located, than in other areas. The depth of the recess can be, for example, at least 14 mm, and the thickness of the remaining furniture panel material within the recess can range from approximately 1 to 10 mm.
[0015] In a further advantageous embodiment of the furniture panel, the mounting element is firmly bonded into the recess. Bonding saves space and can be implemented even when the remaining thickness of the furniture panel is minimal in the area of the recess. With full-surface or almost full-surface bonding of the side wall of the mounting element to the furniture panel, the furniture panel can have a particularly thin material thickness in the area of the recess, creating a maximum depth of installation space for the movement fitting.
[0016] Alternatively or in addition to the bonding, the side wall can have several shaped elements, e.g. spikes, which can be pressed into the counter surface of the recess and which also create a stabilizing connection.
[0017] In a further advantageous embodiment of the furniture panel, its end face with the recess is provided with a narrow-side coating, e.g., an edge banding. Preferably, one end face of the side wall is aligned with the end face containing the recess, and the end face of the side wall is – preferably essentially completely – covered by the narrow-side coating.
[0018] In a further advantageous embodiment of the furniture panel, the mounting element has an inwardly curved side wall which, when the motion fitting is inserted, deforms into an almost flat side wall and thus, through the pre-tension during gluing, ensures a secure fit of the side wall of the mounting element to the recess of one of the partial panels.
[0019] In a further advantageous embodiment of the furniture panel, guides, particularly in the form of guide webs, are arranged or formed on the mounting element, which enable the movement fitting to be inserted parallel to the side wall of the mounting element. The guides can be arranged or formed on the side wall, but also on any side sections that may be present and protrude perpendicularly from the side wall. The guides enable the movement fitting to be inserted from the front side.
[0020] Preferably, locking devices are provided by which the motion fitting locks onto the mounting element. The locking devices can preferably be locking springs arranged or formed on the side wall and / or on the side sections and / or on the motion fitting itself. The locking springs can be arranged and designed such that the locking of the motion fitting is released by inserting a tongue of a removal tool into a gap between the mounting element and the motion fitting. This allows the motion fitting to be removed again, if necessary for repair, maintenance, or replacement.
[0021] In a further advantageous embodiment of the furniture panel, the mounting element is made of a metallic material, wherein the elastic modulus of the metallic material is at least a factor of 10 higher than the elastic modulus of a furniture panel material or furniture panel composite material. Such a large difference in the elastic modulus (E-modulus), particularly with regard to tensile loading, makes it possible to compensate for a material weakening of the furniture panel caused by the recess with a relatively thin side wall of the mounting element. In this way, space is created for the movement fitting without reducing the strength or stability of the furniture panel. The E-modules of typical materials or composite materials for furniture panels range from approximately 1000 to approximately 6500 N / mm² (Newtons per square millimeter).
[0022] A method according to the invention for integrating a mounting element into a furniture panel assembled from at least two partial panels comprises the following steps: At least one recess is provided in at least one of the partial panels. A motion fitting or a non-functional fitting pattern is then inserted into the mounting element, and an adhesive layer is applied to at least one side of the mounting element. The adhesive layer, the at least one side of the mounting element, and / or the recess have a structured surface. The assembly consisting of the motion fitting or the non-functional fitting pattern and the mounting element is inserted into the recess of one of the partial panels, and a further adhesive layer is applied to at least one side surface of the other partial panel.The two partial panels are joined together so that the assembly consisting of the movement fitting or the non-functional fitting pattern and the mounting element is enclosed between the two partial panels. The furniture panel is then pressed together with the integrated mounting element and the inserted movement fitting or the non-functional fitting pattern. The non-functional fitting pattern is removed after pressing and the movement fitting is inserted.
[0023] The textured surface of the adhesive layer or one of the two surfaces (of the mounting element or the recess) to be bonded together allows for the compensation of manufacturing tolerances, specifically manufacturing tolerances in the thickness of the mounting element, i.e., in a direction perpendicular to its planar extent, and manufacturing tolerances in the depth of the recess in the furniture panel. This tolerance range ensures, on the one hand, that the adhesive bond adheres well on both sides and, on the other hand, that the mounting element does not show through on the outer surfaces of the furniture panel during pressing.
[0024] In a further advantageous embodiment of the method, the adhesive layer comprises adhesive in the form of a plurality of structural elements. These structural elements are, for example, three-dimensional elements, in particular pyramids, truncated pyramids, cones, or truncated cones. They are preferably arranged at intervals from one another, so that after the application of the adhesive layer, spaces remain between adjacent structural elements. To compensate for tolerances, displaced adhesive can thus flow into these spaces. In this way, the adhesive layer can be compressed to a minimum thickness, which is reached when the displaced adhesive fills the spaces.
[0025] In a further advantageous embodiment of the process, approximately 10 to 300 structural elements per cm² (square centimeter) are present in the adhesive layer. At this number, and with typical suitable adhesive viscosities in the range of approximately 15,000 mPas (millipascal seconds), the structural elements can be easily molded and retain their shape until compression. If the adhesive is too viscous during application and / or the number of structural elements per area is too high, deformation of the structural elements to compensate for tolerances is either impossible or only partially successful. If the viscosity or the number per area is too low, the structural elements migrate, and tolerance compensation is also not possible.
[0026] In a further advantageous embodiment of the method, the adhesive layer contains between 50 g / m 2 and 350 g / m 2 (grams per square meter) of adhesive, and preferably between 150 g / m 2 and 250 g / m 2 . The adhesive can be applied using a preferably textured roller.
[0027] A furniture body according to the invention or a piece of furniture according to the invention with a wall, in particular a side wall, has a furniture panel as described above. This results in the advantages described in connection with the furniture panel or the manufacturing method for the furniture panel.
[0028] The invention is explained in more detail below with the aid of exemplary embodiments and figures. The figures show: Fig. 1: A piece of furniture with a side panel featuring an integrated flap fitting; Fig. 2: A diagram illustrating a manufacturing process for a furniture panel with an integrated mounting element for a motion fitting; Fig. 3: An isometric view of a mounting element with a partially inserted motion fitting; Fig. 4: An isometric view of a partially assembled furniture panel; Fig. 5: A schematic isometric view of an adhesive layer; Figs. 6 and 7: Two further isometric views of the partially assembled furniture panel and of parts of the furniture panel during the manufacturing process, respectively; Fig. 8: An isometric view of the finished furniture panel; Figs. 9a and 9b: Side views illustrating tolerance compensation by means of an adhesive layer; and Fig. 10: An isometric view of the mounting element with the inserted motion fitting according to... Fig. 3 and a removal tool.
[0029] In all figures, identical reference symbols identify identical or equivalent elements. For reasons of clarity, not every element in the figures is provided with a reference symbol.
[0030] In this description, terms such as top, bottom, left, and right refer exclusively to the exemplary representation chosen in the respective figures. The terms "front" and "back" refer to the orientation of the furniture body, with the front side indicating the open side of the furniture body, which is usually facing the user.
[0031] Fig. 1 shows in an isometric representation an upper cabinet, for example of a kitchen, as an embodiment of a piece of furniture, the side walls 13 of which are formed by furniture panels 40 which have an integrated mounting element 50 for a movement fitting 30.
[0032] The wall unit comprises a furniture body 10 with a base 11 and a top 12 as well as two side walls 13. A rear wall is preferably present, among other things, for stability reasons, but is not visible in this embodiment.
[0033] The furniture body 10 is open at the front to provide access to the interior of the cabinet. A flap assembly 20 with, in this example, a one-piece flap 21 is provided to close the opening of the furniture body 10. The one-piece flap 21 is pivotally mounted along its upper horizontal side edge. For this purpose, the movement fittings 30 are provided, which are connected to the one-piece flap 21 by a lever mechanism 33 in the upper area of the flap.
[0034] The movement fittings 30 - hereinafter also referred to as fittings 30 - are arranged (except for the lever mechanism 33 extended in the illustrated open position) within the respective side wall 13 in mounting elements 50 which are integrated into the side wall 13. In the closed state of the flap 21, the lever mechanism 33 is completely retracted into the side wall 13, except for mounting elements for connection to the flap 21. The area within the side wall 13 in which the fitting 30 is located is in the Fig. 1 indicated by a dashed line.
[0035] The side panel 13 is characterized by side surfaces that are ideally made in one piece and have a consistently uniform surface finish across their entire area. The surface of the one-piece side surfaces can create design effects through various patterns, surface textures, or colors. This applies preferably to both an outer side surface and an inner side surface facing the interior of the furniture carcass 10. The side panels 13 also have an end face with an opening in the area of the fitting 30, into which the lever mechanism 33 of the fitting 30 extends and from which it extends. When the flap assembly 20 is closed, the lever mechanism 33 is completely immersed in the opening, except for any fasteners by which it is connected to the one-piece flap 21.
[0036] According to the application, the side walls 13 are formed by furniture panels 40, the manufacture and construction of which are explained in more detail below in an exemplary embodiment
[0037] In Fig. 2 A method for producing a furniture panel 40 with an integrated mounting element 50 for receiving a fitting 30 is schematically explained.
[0038] In the illustrated embodiment, the furniture panel 40 is composed of two partial panels 41 and 42. In this example, recesses 411, 421 are formed in the partial panels 41, 42, mirroring one another. When the partial panels 41, 42 are placed on top of one another, the recesses 411, 421 complement each other to form a cavity in which the mounting element 50 with the fitting 30 is positioned. Since each recess 411, 421 only partially accommodates the combination of mounting element and fitting 30, the recesses 411, 421 are hereinafter also referred to as partial recesses 411, 421.
[0039] In a first step S1, the fitting 30 is inserted into the mounting element 50. In the Fig. 3 the fitting 30 partially inserted into the mounting element 50 is shown in more detail.
[0040] The mounting element 50 has a rectangular, flat base plate 51 and three side sections 52. The side that will later face the front of the furniture panel 40 remains open. The base plate 51 is preferably formed integrally with the side sections 52 and can be made, for example, from sheet steel, with the side sections 52 bent from the base plate 51. The mounting element 50 can thus be manufactured cost-effectively, for example, as a stamped and bent part.
[0041] In the example shown, the fitting 30 is cassette-shaped and has two parallel side plates 31, 32, which are spaced apart from each other by a frame 34. Components of the fitting 30, such as the one in Fig. 1 The extendable lever mechanism 33 shown is attached to the side plates 31, 32 via rivets or other fastening elements. This is done in such a way that the side plates 31, 32 are as flat as possible and, in particular, in such a way that the fastening elements used do not protrude beyond the side plates 31, 32.
[0042] The frame 34 runs along at least the upper and lower sides and preferably also along the rear side of the fitting 30 and, together with the side plates 31, 32, forms a housing of the fitting 30.
[0043] On the upper and lower sides (not visible here), the frame 34 is slightly offset inwards relative to the side plates 31, 32, so that a U-shaped guide profile is formed in each case.
[0044] To secure the fitting 30 in the mounting element 50, a guide rail 53 is arranged on both the lower and upper side sections 52. When the fitting 30 is inserted, the side plates 31, 32, which project slightly upwards and downwards respectively, engage the sides of the guide rails 53, thus fixing the fitting 30 in a direction perpendicular to the side surface of the furniture panel 40. Furthermore, in the example shown, inwardly projecting locking springs 54 are arranged in front of the guide rails 53 (viewed in the insertion direction of the fitting 30). These springs lock the fitting 30 in the inserted position. A locking recess 35 is provided at a suitable location in the frame 34, into which the locking spring 54 engages. This ensures that the fitting 30 is secured not only laterally by the guide rail 53, but also in the insertion direction, preventing it from being easily removed forwards.Spring elements 55 are also arranged on the rear side section 52 of the mounting element 50 as seen in the insertion direction, the function of which is described below in connection with . Fig. 10 will be explained later.
[0045] As in connection with the Fig. 10 As will be described in more detail below, with the furniture panel 40 according to the application, it is possible to remove and reinsert the fitting 30 from the mounting element 50 even when the furniture panel 40 is fully assembled. For this reason, in an alternative embodiment of the method, in step S1, a non-functional fitting sample (dummy) can also be inserted into the mounting element 50 instead of the fitting 30, which is removed after the method has been completed. The fitting sample should have the same external dimensions as the fitting 30 to be inserted later.
[0046] In a second step S2, the base plate 51 of the mounting element 50 is provided with an adhesive layer 60. Details regarding the adhesive layer 60 are described below in connection with the Fig. 5 and 9a , 9b explained.
[0047] In a next step S3, the assembly consisting of mounting element 50 and fitting 30 is inserted into the partial recess 411 of a first of the partial plates, in this case partial plate 41. Fig. 4 This partial plate 41 and the arrangement of the mounting element 50 and fitting 30 before and during insertion are shown again in an enlarged view. The base plate 51 with the adhesive layer 60 points toward the recess 411.
[0048] In the Fig. 5 The adhesive layer 60 on the base plate 51 is shown in an enlarged detail. The figure shows that the adhesive layer 60 has a plurality of structural elements 61, which here have the shape of truncated pyramids. A preferably regular arrangement of the structural elements 61 forms the adhesive layer 60 on the base plate 51. The density of the structural elements 61 is, for example, in a range between approximately 10 and 300 elements / cm².
[0049] It is noted that instead of forming the structural elements 61 as truncated pyramids, other three-dimensional geometric shapes such as truncated cones, cylinders, or teardrop-like structures can also be used. It is also possible to apply the adhesive in linear structural elements extending in one direction. Furthermore, it is conceivable that the adhesive layer 60 consists of a continuous adhesive layer and the applied structural elements. It is important to note that the height of the adhesive layer 60 is not uniform across the wetted area; that is, no layer with a homogeneous thickness is applied.
[0050] The adhesive used in the adhesive layer 60 is preferably a high-viscosity adhesive that retains the structure shown after application and ideally does not lose this structure due to the assembly's own weight even after the assembly comprising the mounting element 50 and the fitting 30 has been inserted into the partial panel 41. The adhesive layer 60 is applied, for example, using textured rollers that form the structural elements 61. The amount of adhesive used can be in a range between 50 g / m 2 and 350 g / m 2 (grams per square meter), preferably in a range from 150 g / m 2 to 250 g / m 2 .
[0051] The viscosity of the adhesive at processing temperature (e.g., 120°C) is approximately 15,000 mPas (millipascal-seconds). If the adhesive is too viscous during application, deformation of the structural elements 51 to compensate for tolerances is either impossible or only partially successful. If the viscosity is too low, the structural elements 51 will deform, and tolerance compensation will also be impossible.
[0052] A reactive polyurethane hot melt adhesive is preferably used. The polymers react with atmospheric moisture and cross-link to form polyurethane. Upon cooling, the adhesive solidifies and no longer allows further processing; therefore, processing must take place within the adhesive's so-called "open time." In principle, the described process can also be carried out with other types of adhesives.
[0053] Again with reference to Fig. 2 In a next process step S4, the second of the partial plates, the partial plate 42, is also provided with an adhesive layer, which can be a continuous adhesive layer or an adhesive layer 60, which also has structural elements 61. Due to the application of the adhesive to the second partial plate 42 with the aid of a roller, the area of the partial recess 421 remains free of adhesive. The second partial plate provided with the adhesive layer 60 is in the Fig. 6 shown again enlarged. The multitude of regularly arranged structural elements 61 is clearly visible.
[0054] In a step S5, the first partial panel 41 with the inserted arrangement of mounting element 50 and fitting 30 and the second partial panel 42 are joined to one another and in a step S6 the furniture panel 40 thus produced is pressed by applying pressure in a press, for example a laminating press, until the adhesive layer 60 hardens.
[0055] If necessary, pressing can be performed with heat and / or cooling to assist or initiate the curing of the adhesive. For example, adhesive that can be reactivated by heat can be used in conjunction with a heat-activated press, allowing waiting or storage times to be inserted between steps S4 and S5.
[0056] The press can, for example, be designed as a stamping press with a positively guided stamp, thus preventing the partial plates 41, 42 from slipping relative to each other. Alternatively or additionally, it is conceivable to hold the two partial plates 41, 42 in position during pressing to prevent slipping relative to each other, particularly at the front edges. To achieve an attractive appearance, the front edges should be flush with each other.
[0057] The Fig. 7 shows the joining of the two partial plates 41, 42 and the arrangement of mounting element 50 and fitting 30 and the Fig. 8 Finally, the assembled furniture panel 40, finished by pressing, is produced. The joint between the sub-panels 41 and 42, which may be slightly visible, can be used as a design element. In particular, one of the sub-panels, for example sub-panel 41, can consist of two or more layers, e.g., an outer layer of a wood-based material (possibly with a decorative laminated layer on the outside) and an inner layer of glass, plexiglass, or metal. The corresponding partial cutout 411 penetrates the inner layer and extends into the outer layer. The other sub-panel 42 is again made of the wood-based material with the same thickness as the outer layer of sub-panel 41. This results in a composite furniture panel 40 with a middle layer of glass, plexiglass, or metal, which conceals the joint between the sub-panels.If a middle layer made of a transparent or at least translucent material is used, light can be shone in from the side, which spreads through internal reflection so that it emerges at the edges, which can represent an additional design element.
[0058] In the Fig. 9a and 9b The interaction of the adhesive layer 60 with the base plate 51 and the sub-plate 41 is explained in more detail in the form of a schematic side view.
[0059] The Fig. 9a Figure 1 shows a maximum distance dmax between the base plate 51, wetted with the adhesive layer 60, and the attached sub-plate 41. This maximum distance dmax is only slightly less than the height h that the structural elements 61 of the adhesive layer 60 exhibit after application. A certain pressure between the assembly of fitting 30 and mounting element 50 and the sub-plate 41, which leads to the deformation of the structural elements 61 shown, is required to ensure that the adhesive of the adhesive layer 60 bonds well with the surface of the sub-plate 41. When the adhesive layer 60 hardens in the Fig. 9a As shown in the diagram, a strong adhesive bond exists despite the remaining distance d max. Gaps 62 remain between the structural elements 61, but these do not impair the strength of the cured adhesive layer 60.
[0060] Fig. 9b The adhesive layer 60 is shown when the sub-plate 41 is moved maximally towards the base plate 51 and is consequently at a minimum distance d min to the base plate 51. The original shape of the structural elements 61 with height h is shown in the Fig. 9b (as well as in the Fig. 9a ) for illustration purposes. In the illustrated state, adhesive 63 displaced from the partial plate 41 has been forced into the now filled spaces 62, which are Fig. 9a The unfilled spaces were pressed. The minimum possible distance d min between the base plate 51 and the sub-plate 41 in the adhesive layer 60 is achieved when the displaced adhesive 63 completely fills the free spaces 62.
[0061] The Fig. 9a and 9bshow that the adhesive layer 60, through the structural elements 61, is able to compensate for tolerances - in particular due to the (wood) processing of the partial panels 41, 42 - by a variable thickness of the cured adhesive layer 60 between d min and d max. The large tolerance range ensures that, on the one hand, the adhesive bond adheres well on both sides (in the case of partial recesses 411, 421 that are too deep) and, on the other hand, that the arrangement of the fitting 30 and the mounting element 50 does not press into the outer surface of the partial panels 41, 42 during pressing (in the case of partial recesses 411, 421 with too small a depth). Since the correct position of the mounting element 50 results in the step of pressing the two partial panels 41, 42, the Fig. 2 The procedure described is carried out with the fitting 30 or fitting pattern inserted.
[0062] It is noted that, alternatively or additionally, the surface of the mounting element 50 can also have a structured surface. An applied layer of adhesive 60, which can then have a uniform thickness, can also compensate for tolerances in this case, since excess adhesive can be absorbed into the structured surface of the mounting element 50. The same applies if the surface to be bonded of the partial recesses 411, 421 is structured.
[0063] The inserted state of the fitting 30 in the mounting element 50 is in the Fig. 10 The Fig. 10 the application of a removal tool 70, which has a front handle part 71 and two strip-shaped insertion tongues 72 projecting perpendicularly therefrom and aligned parallel to one another. The insertion tongues 72 are inserted, resting against the frame 34, between the side sections 52 of the mounting plate 50 and the fitting 30 and lever the locking spring 54 out of the locking recess 35. After inserting the removal tool 70, the locking of the locking springs 54 in the locking recesses 35 is thus released, and the fitting 30 can be removed forward in order to repair or replace it if necessary.
[0064] The removal of the fitting 30 is carried out by the Fig. 3 The visible spring elements 55 support the mechanism. The spring elements 55 are tensioned when the fitting 30 is inserted and spring back after the detent between the detent spring 54 and the detent recess 35 is released, pushing the fitting 30 forward in the removal direction so that it can then be easily gripped by a user.
[0065] The furniture plate 40 shown thus allows the fitting 30 to be replaced when the furniture body or furniture is assembled.
[0066] Alternatively, the use of other materials such as plastic or light metal is also possible for the mounting element 50. When using plastic, a biopolymer material can be used, which simplifies recycling of the furniture panel 40. The mounting element 50 can also be manufactured in multiple parts, with the detent springs 54 and spring elements 55 being formed separately from an elastic, springy material.
[0067] In a further development of the furniture panel 40, the mounting element 50 can be provided with a receptacle to which a cover, e.g., a frame-like cover, can be attached. This cover conceals the edges of the fitting 30 so that they are as invisible as possible through the front opening of the furniture panel 40. The cover can be attached to the receptacle, for example, by clipping, clamping, plugging, or screwing.
[0068] In the illustrated embodiments, the end-face opening of the furniture panel 40 already exists when the two partial panels 41, 42 are joined, since the recesses 411, 421 extend into the side surfaces 412, 422. In an alternative embodiment, the recesses 411, 421 can be designed such that they do not extend into the side surfaces 412, 422, but rather that material remains between the mounting element 50 and the side surfaces 412, 422 of the partial panels 41, 42, and thus also between the end face of the furniture panel 40. The mounting element 50, optionally with the fitting 30 already installed, is then initially completely embedded in the furniture panel 40. In this case, the end-face opening is subsequently created in the furniture panel 40 from the end face, in particular by milling. For this purpose, the mounting element 50 may have a section of suitably machinable material into which a milling operation is carried out to form a defined edge.If a cover is provided for the edge of the fitting, which is fixed to the mounting element 50, this can be inserted after the opening has been milled.
[0069] As a further embodiment, the mounting element 50 has a curved base plate 51 facing inward toward the fitting 30 to be inserted. When the fitting 30 is inserted into the mounting element 50, the curvature facing the fitting deforms elastically outward, so that the base plate is deformed into an approximately flat shape. When the mounting element is glued into the recess 411 of one of the partial plates 41, the prestressing ensures that the fitting 30 is supported and positioned with respect to the mounting element 50, as well as the mounting element 50 with respect to the partial plate 41, with virtually no play.
