Description

Method and assembly for integrating assembly elements of movable accessories into furniture panels Furniture panels for ready-to-assemble elements

technical field

The invention relates to a method for integrating an assembly element of a mobile fitting into a furniture panel. The invention also relates to a furniture panel having an integrated assembly element receiving a movable fitting for a movable furniture part, wherein the assembly element has at least one side wall and is inserted into a recess of the furniture panel. Furthermore, the present invention relates to a furniture body or furniture having such a furniture panel.

Background technique

The body of the furniture is usually made of furniture panels based on wood or wood materials, for example particleboard or medium or high density fiberboard (MDF, HDF). Connection fittings, movable fittings or other functional fittings are used to connect furniture panels to each other or for the hinged connection of movable furniture parts such as doors or flaps, and are collectively referred to herein as functional parts. Accessories are usually made of plastic and/or metal materials. In particular, larger fittings are usually placed on furniture panels and screwed thereon. The larger fittings then protrude into the interior of the furniture body so that when the door or flap is closed, the larger fittings are not visible, but when the door or flap is open, the larger fittings detract from the appearance of the furniture body And reduce the usable internal volume of the furniture body. It is also known to fit smaller fittings into holes or recesses.

The printed publication DE 20 2014 105 730 U1 describes a furniture panel having an insert from one side of the furniture panel in a material recess which can accommodate a movable fitting. The material recess may be provided with an undercut to secure the insert part at least in a direction perpendicular to the surface of the furniture panel. There are no further details on how to fasten the insert to the furniture panel or to fasten the movable accessories to the insert. The advantage of arranging the insert in the recess of the furniture panel is that the inserted movable fitting is fully or partially embedded with respect to the surface of the furniture panel, so that it does not protrude into the interior of the furniture panel or only to a lesser extent into the furniture inside the panel. However, the movable fitting is also visible on at least one side of the furniture panel and prevents the sides of the furniture panel from being homogeneous in terms of visibility and in terms of material and composition.

The applicant's subsequently published document DE 10 2017 104 170 A1 describes a furniture panel in which box-like fittings are integrated such that the side surfaces of the furniture panel are substantially flat. For this purpose, the furniture panel is assembled from two sub-panels separated along a central plane, in which a recess with a mirror-inverted profile is made in the two sub-panels, eg milled into the sub-panel. When assembling the furniture panel, the recess is A cavity is formed into which the fitting is inserted, eg glued. In this case, the sides of the furniture panel are not affected by the accessories in terms of their appearance, surface finish and/or material.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a furniture panel with integrated assembly elements, wherein the side surfaces of the furniture panel are unaffected by movable fittings in terms of their appearance, surface finish and/or material, and which can nevertheless be replaced .

This object is solved by a furniture panel and a method for producing a furniture panel with the features of the corresponding independent claims. Advantageous designs and further developments are the subject of the dependent claims.

A furniture panel of the above-mentioned type according to the invention is characterized in that the furniture panel is assembled from at least two sub-panels, and in that the recess is in at least one sub-panel from a side surface of the sub-panel and at least one end surface of the furniture panel extends and the recess is directed towards at least one other sub-panel, wherein at least the side walls of the assembly element are connected in a force-fit or materially bonded manner to opposite surfaces of the recess and the assembly element has means for securing the movable fitting. Thereby, the movable fitting can be inserted substantially completely into the furniture panel, wherein the movable part of the movable fitting can be removed from an end face of the furniture panel.

With this assembly element, the mobile fitting can be inserted through the front opening in the furniture panel and removed again if necessary. The assembly elements are already integrated into the furniture panel during the manufacture of the furniture panel. By assembling two sub-panels into a furniture panel, the recesses that accommodate the assembly elements can be inserted into large areas from one side of the sub-panels. This creates a recess which can also accommodate corresponding large assembly elements for large movable fittings such as flap fittings. The assembly element may for example be box-shaped and have two opposite side walls.

The fact that the movable fitting can be inserted "substantially completely" into the furniture panel is to be understood such that any slight protrusion of the movable fitting relative to the end face of the furniture panel is so small as to not impair the passage of movable furniture parts (doors, panels, front panels, etc.) to close the furniture body or furniture. The possible protrusion is preferably less than about 1-3 millimeters (mm). A protrusion of this size is usually within the existing gap width between the furniture body and the movable furniture part, or can be compensated for by narrow side coatings (eg, edge strips). It should also be understood that the fitting is (only) within the furniture panel in its retracted state, with the movable furniture part closing the furniture body. When the furniture part is opened, the extension part of the movable fitting, eg the lever mechanism, protrudes above the end face.

In an advantageous configuration of the furniture panel, a recess is introduced into one of the sub-panels, while the other sub-panel is formed in a flat manner and has no recess. Alternatively, (partial) notches are provided in both sub-panels, which together form the indent after the sub-panels are joined together. The sub-recesses can be mirror-symmetrical, but need not be.

A recess or sub-recess can be (subsequently) inserted into the sub-panel, preferably milled or stamped. Thus, the sub-panels can first be produced in a conventional manner, for example from wood or wood composite material without notches, and then the notches can be made. This can preferably be done from the side surface. Alternatively, the recesses can be made with the sub-panel in the main moulding process, eg, in the foaming or casting process.

In another advantageous design of the furniture panel, the recess has a constant depth on its surface. This is an easy-to-produce form of notches, especially when milling (sub)notches. In principle, however, other shapes are also possible, for example a recess that is stepped in depth, wherein the recess is deeper in the region of the movable fitting in which the movable fitting element such as a lever is arranged than in other regions. The depth of the recess may for example be at least 14 mm and the thickness of the material of the furniture panel remaining in the area of the recess may be between about 1 mm and 10 mm.

In a further advantageous configuration of the furniture panel, the assembly elements are glued into the recesses by means of material bonding. Gluing saves space and can also be done in the recessed area if the remaining material thickness of the furniture panel is small. If the side wall of the assembly element is glued to the furniture panel over the entire surface or almost the entire surface, the material thickness of the furniture panel in the area of the recess may be particularly small, thereby creating a maximum depth of installation space for the movable accessories.

As an alternative to or in addition to gluing, the side walls may have a plurality of shaped elements, such as spikes, which may be pressed into the opposite surfaces of the recess and which may also establish a stable connection.

In another advantageous design of the furniture panel, its end face is provided with a recess with a narrow side coating, such as an edge strip. Preferably, one end face of the side wall is oriented towards the end face provided with the recess, and the end face of the side wall is - preferably substantially completely - covered by the narrow side coating.

In another advantageous design of the furniture panel, the assembly element has an inwardly curved side wall, which, when the movable fitting is inserted, is deformed into an almost flat side wall, thus ensuring that the assembly element is assembled due to the pretensioning during the gluing process A firm contact between the sidewall of the subpanel and the notch in one of the sub-panels.

In another advantageous design of the furniture panel, guides, in particular in the form of guide webs, are arranged or formed on the assembly element, which guides enable the insertion of the movable fitting parallel to the side walls of the assembly element. The guides can be arranged or formed on the side walls, but can also be arranged on any existing side sections that protrude vertically from the side walls. The guide allows the movable fitting to be inserted from the front.

A locking device is preferably provided by means of which the movable fitting engages with the assembly element. The locking means may preferably be a locking spring which is arranged or formed on the side wall and/or on the side section and/or on the movable fitting. The catch spring may be arranged and formed such that the catch of the movable fitting is released by inserting the insertion tongue of the removal tool into the gap between the assembly element and the movable fitting. In this way, the movable accessory can optionally be removed again for repair or maintenance or replacement.

In another advantageous design of the furniture panel, the assembly element is made of a metallic material, wherein the elastic modulus of the metallic material is at least ten times higher than that of the furniture panel material or the furniture panel composite. This large difference in modulus of elasticity (e-modulus), especially with respect to tensile loads, makes it possible to use the relatively thin side walls of the assembly element to compensate for material weakening of the furniture panel through the recess. In this way, space is created for movable accessories without reducing the strength or stability of the furniture panel. Typical materials or composites for furniture panels have elastic moduli in the range of about 1000 to about 6500 N/mm ² (Newtons per square millimeter).

The method according to the invention for integrating an assembly element into a furniture panel assembled from at least two sub-panels comprises the steps of forming at least one recess in the at least one sub-panel. Additionally, a sample of the movable or non-functional accessory is inserted into the assembly element and a layer of adhesive is applied to at least one side of the assembly element. The adhesive layer, at least one side of the assembly element and/or the recess have a structured surface. A device consisting of samples of movable or non-functional accessories and assembly elements is inserted into the recess of one of the sub-panels, and another layer of adhesive is applied to at least one side surface of the other sub-panel. The two sub-panels are connected together so that a device consisting of samples of movable or non-functional accessories and assembled elements is surrounded by two sub-panels. Then, press the furniture panel with the integrated assembly element and the inserted movable or non-functional accessory sample.

The textured surface of the adhesive layer or one of the two surfaces (of the assembly element or recess) to be glued together can compensate for manufacturing tolerances, in particular the thickness of the assembly element (ie the direction extending perpendicular to its plane) ) and manufacturing tolerances for the depth of notches in furniture panels. The tolerance range allows good adhesion of the adhesive to both sides on the one hand, and on the other hand that the assembly elements do not appear in the outer surface of the furniture panel during the pressing process.

In a further advantageous configuration of the method, the adhesive layer has adhesive in the form of a plurality of structural elements. Structural elements are, for example, three-dimensional elements, in particular cones, truncated cones, cones or truncated cones. They are preferably arranged spaced apart from each other so that after the adhesive layer has been applied there is free space between adjacent structural elements. To compensate for tolerances, the adhesive displaced in this way can escape into free space. In this way, the adhesive layer can be compressed to a minimum thickness, which is achieved when the displaced adhesive fills the free space.

In another advantageous design of the method, there are approximately 10 to 300 structural elements per square centimeter (square centimeter) in the adhesive layer. At the numbers mentioned, structural elements can easily be formed with typical suitable viscosities for adhesives in the range of 15,000 mPas (milliPascal seconds), and they retain their shape until pressed. If the adhesive is too viscous at the time of application and/or the number of structural elements per unit area is too high, deformation of the structural elements for tolerance compensation is not possible or only incomplete. If the viscosity or quantity per unit area is too low, the structural element will run and tolerance compensation will also not be possible.

In another advantageous design of the method, the adhesive layer has an adhesive between 50 g/m ² and 350 g/m ² (grams per square meter), and preferably between 150 g/m ² and 250 g/m 2 between ² . The adhesive can be applied by a preferably structured roll.

The furniture body or furniture with walls, in particular side walls, according to the invention has a furniture panel as described above. The advantages described in connection with a furniture panel or a method of manufacturing a furniture panel are obtained.

Detailed ways

The same reference numbers refer to the same or similar acting elements throughout the drawings. For the sake of clarity, not every element in all figures is labeled with a reference number.

In the specification, terms such as up, down, left, and right refer specifically to the exemplary representations selected in the various figures. The terms "front" and "rear" refer to the orientation of the furniture body, where the front side refers to the open side of the furniture body generally facing the user.

FIG. 1 shows an isometric view of an embodiment of a furniture such as a wall unit of a kitchen, the side walls 13 of which are formed by furniture panels 40 with integrated assembly elements 50 for movable fittings 30 .

The wall unit comprises a furniture body 10 having a bottom panel 11 and a top panel 12 and two side walls 13 . A rear panel is particularly preferred for stability reasons, but is not visible in this design example.

The furniture main body 10 is open to the front to enter the interior of the cabinet. In this example, a flap arrangement 20 with an integral flap 21 is provided to close the opening of the furniture body 10 . The one-piece flap 21 is hinged along its upper horizontal side edge. For this purpose, a movable fitting 30 is provided, which is connected to the one-piece flap 21 in the upper region of the one-piece flap 21 by means of a lever mechanism 33 .

(except for the lever mechanism 33, which extends in the open position shown) movable fittings 30 (also referred to as fittings 30 in the following) are arranged in respective side walls 13 of assembly elements 50 into which the assembly elements 50 are integrated. When the flap 21 is closed, the lever mechanism 33 is fully retracted into the side wall 13 , optionally except for assembly elements for connection with the flap 21 . The area within the side wall 13 where the fittings 30 are located is indicated by dashed lines in FIG. 1 .

The side wall 13 is characterized in that the side surface is ideally formed in one piece and can have a uniform surface texture over the entire surface. The surface of the one-piece side can be designed with different patterns, surface textures or different colors. Preferably, this applies both to the exterior of the side surface and to the interior of the side surface facing the interior of the furniture body 10 . Furthermore, the side wall 13 has an end face which has an opening in the region of the fitting 30 into which the lever mechanism 33 of the fitting 30 enters or from which the lever mechanism 33 exits. In the closed state of the flap device 20 , the lever mechanism 33 is fully immersed in the opening, except for any fastening means by which the lever mechanism is connected to the flap 21 , which is here of a one-piece construction.

According to the present application, the side wall 13 is formed by a furniture panel 40, the manufacture and construction of which is explained in more detail later in the example of embodiment.

FIG. 2 schematically shows a method for manufacturing a furniture panel 40 with an integrated assembly element 50 accommodating an accessory 30 .

In the embodiment shown, the furniture panel 40 is assembled from two sub-panels 41 and 42 . In this example, the notches 411, 421 are introduced into the sub-panels 41, 42 in mirror images of each other. When the sub-panels 41 , 42 are placed on top of each other, the notches 411 , 421 complement each other to form a cavity in which the assembly element 50 is positioned together with the fitting 30 . The recesses 411 , 421 are also referred to as the sub-recesses 411 , 421 below, as each recess only partially accommodates the assembly element and fitting 30 combination.

In a first step S1 , the fitting 30 is inserted into the assembly element 50 . FIG. 3 shows in more detail that the fitting 30 is partially inserted into the assembly element 50 .

The assembly element 50 has a rectangular flat base plate 51 and three side sections 52 , wherein the side facing the front side of the furniture panel 40 later remains open. The base plate 51 is preferably formed integrally with the side sections 52 , from which the side sections 52 are bent, and may for example be made of steel sheet. Thus, the assembly element 50 can be cost-effectively manufactured as, for example, stamped and bent parts.

In the example shown, the fitting 30 is box-shaped and has two parallel side panels 31 , 32 separated by a frame 34 . Components of the fitting 30, such as the retractable lever mechanism 33 shown in Figure 1, are attached to the side panels 31, 32 by means of rivets or other fixing elements. This is done so that the side panels 31 , 32 are as flat as possible, in particular so that the fixing elements used do not protrude beyond the side panels 31 , 32 .

The frame 34 extends at least along the upper and lower sides, and preferably also along the rear side of the fitting 30 , and together with the side plates 31 , 32 form the housing of the fitting 30 .

On the upper and lower sides, which are not visible here, the frame 34 is slightly offset inwards relative to the side plates 31 , 32 , so as to respectively form a U-shaped guide profile.

For fixing the fitting 30 in the assembly element 50 , guide webs 53 are arranged on the lower and upper sections 52 in each case. When the fitting 30 is inserted, the side panels 31 , 32 projecting slightly upwards or downwards surround the sides of the guide web 53 , thus securing the fitting 30 in a direction perpendicular to the side surfaces of the furniture panel 40 . Furthermore, in the example shown, in front of the guide web 53 (as seen in the insertion direction of the fitting 30 ) is an inwardly protruding catch spring 54 with which the fitting 30 engages in the inserted state. For this purpose, a catch recess 35 is arranged at a suitable position in the frame 34, into which catch spring 54 engages, so that the fitting 30 is not only fixed laterally by the guide web 53, but also with regard to the insertion The orientation is fixed and it is no longer easy to move forward. In addition, a spring element 55 is arranged on the rear side section 52 of the assembly element 50 , seen in the insertion direction, the function of which is explained below in conjunction with FIG. 10 .

As described in more detail in connection with FIG. 10 , even if the furniture panel 40 has been fully assembled, the fitting 30 can be removed from the assembly element 50 and reinserted in accordance with the present application. For this reason, in an alternative design of the method in step S1, a non-functional fitting sample (dummy) can also be inserted into the assembly element 50 instead of the fitting 30, the fitting sample being removed after the method is completed. The external dimensions of the accessory sample should be the same as the accessory 30 to be inserted later.

In the second step S2 , the substrate 51 of the assembly element 50 is provided with the adhesive layer 60 . Details regarding the adhesive layer 60 are described below in conjunction with Figures 5 and 9a, 9b.

In the next step S3, the means of assembling the element 50 and the fitting 30 is inserted into the sub-recess 411 of the first sub-panel (currently the sub-panel 41). FIG. 4 shows the sub-panel 41 enlarged again before or during insertion and the means of assembling the element 50 and the fitting 30 . The substrate 51 with the adhesive layer 60 faces the direction of the notch 411 .

In FIG. 5, the adhesive layer 60 on the substrate 51 is shown in an enlarged cross-sectional view. The figure shows that the adhesive layer 60 has a plurality of structural elements 61, here the structural elements have the shape of a truncated pyramid. The preferred regular arrangement of structural elements 61 is formed by the adhesive layer 60 on the substrate 51 . The density of structural elements 61 is, for example, in the range of about 10 to 300 elements/cm ² .

Note that instead of forming the structural elements 61 as truncated pyramids, other three-dimensional geometries such as truncated cones or cylinders or drop-like structures can also be used. The adhesive can also be applied in linear structural elements extending in one direction. It is also contemplated that the adhesive layer 60 consists of a continuous layer of adhesive and applied structural elements. What is important here is that the height of the adhesive layer 60 is not identical over the wetted surface, ie a layer with a uniform layer thickness is not applied.

The adhesive used in adhesive layer 60 is preferably an adhesive with a high viscosity that retains the structure shown after application and even if the arrangement has been inserted into the sub-panel from assembly element 50 and fitting 30 41, the adhesive ideally also does not lose the structure due to the self-weight of the arrangement. The adhesive layer 60 is applied, for example, by a structured roll forming the structural elements 61 . The amount of binder used may be in the range of 50 g/m ² to 350 g/m ² (grams per square meter), preferably in the range of 150 g/m ² to 250 g/m ² .

The viscosity of the adhesive at processing temperature (eg, 120°C) is about 15,000 mPas (milliPascal-seconds). If the adhesive is too sticky during application, deformation of the structural element 51 for tolerance compensation is not possible or occurs only incompletely. If the viscosity is too low, the structural element 51 will operate and tolerance compensation will not be possible.

Preferred adhesives are reactive polyurethane hot melts. The polymer reacts with air humidity/moisture and crosslinks to form polyurethane. Cooling causes the adhesive to solidify and does not allow any further processing, which must therefore take place within the so-called "open time" of the adhesive. In principle, the described method can also be performed with other types of adhesives.

Referring again to FIG. 2, in the next method step S4, the second sub-panel 42 of the sub-panels is also provided with an adhesive layer, which may be a continuous adhesive layer, or may also have structural elements 61 adhesive layer 60. Since the adhesive is applied to the second sub-panel 42 by means of a roller, the area of the sub-notch 421 remains adhesive-free. The second sub-panel provided with the adhesive layer 60 is shown enlarged again in FIG. 6 . A large number of regularly arranged structural elements 61 can be easily seen.

In step S5 the first sub-panel 41 and the second sub-panel 42 with the inserted arrangement of the assembly elements 50 and the fittings 30 are joined together and in step S6 by applying pressure in a press such as a laminator The resulting furniture panel 40 is pressed until the adhesive layer 60 hardens.

Optionally, pressing can be performed with heating and/or cooling to support or cause hardening of the adhesive. For example, adhesives that can be reactivated by supplying heat can be used with a press with supply of heat, which allows a waiting time or storage time to be inserted between steps S4 and S5.

The press can, for example, be designed as a punch with a positively guided ram, so that the sub-panels 41 , 42 are prevented from sliding against each other. Alternatively or additionally, it is conceivable to keep the two sub-panels 41 , 42 in place during pressing to prevent, in particular, the front edges from sliding relative to each other. For an aesthetically pleasing appearance, the front edges should be flush with each other.

Figure 7 shows the joining together of the two sub-panels 41, 42 and the means of assembling the element 50 and the fitting 30, and Figure 8 finally shows the furniture panel 40 joined and pressed together. The junction between the sub-panels 41, 42 is optionally easily visible and can be used as a design element. In particular, one of the sub-panels, eg sub-panel 41, may consist of two or more layers, eg an outer layer of wood material (possibly with a decorative layer laminated on the outside) and an applied inner layer of glass, plexiglass or metal. Corresponding sub-notches 411 penetrate the inner layer and extend into the outer layer. The other sub-panel 42 is again made of wood material, the thickness of which is the thickness of the outer layer of the sub-panel 41 . The result is a composite furniture panel 40 having an intermediate layer of glass, plexiglass or metal through which the joints between the sub-panels are laminated. If a central layer of transparent or at least semi-transparent material is used, light can be radiated from the sides, propagated by internal reflections to emerge at the edges, which may constitute an additional design element.

In Figures 9a and 9b, the interaction of the adhesive layer 60 with the substrate 51 and the sub-panel 41 is detailed in the form of a schematic side view.

Figure 9a shows the maximum distance _dmax between the substrate 51 wetted by the adhesive layer 60 and the attached sub-panel 41 . This maximum distance d _max is much smaller than the height h of the structural elements 61 of the adhesive layer 60 after application. A certain pressure is required between the fitting 30 and the means of assembling the element 50 and the sub-panel 41 (which pressure causes the shown deformation of the structural element 61 ) in order to wet the adhesive of the adhesive layer 60 in a good wetting manner Adhesive to the surface of the sub-panel 41 . If the adhesive layer 60 hardens as in the situation shown in Figure 9a, there is a bond carrying the adhesive despite the remaining distance _dmax . Spaces 62 remain between the structural elements 61 , however, this does not compromise the strength of the cured adhesive layer 60 .

FIG. 9b shows the adhesive layer 60 when the sub-panel 41 is maximally moved towards the substrate 51 and thus at a minimum distance d _min from the substrate 51 . For illustration, the original shape of the structural element 61 of height h is shown in Fig. 9b (as well as Fig. 9a). In the state shown, the adhesive 63 displaced by the sub-panel 41 has been pressed into the now filled free space 62, which is not filled in Figure 9a. The smallest possible distance d _min between the substrate 51 and the sub-panel 41 in the adhesive layer 60 is given when the displaced adhesive 63 completely fills the free space 62 .

Figures 9a and _9b show that the adhesive layer 60 is able to compensate for tolerances, in particular due to the sub-panels ₄₁ , d Compensation tolerance due to (wood) machining of 42. The large tolerance range ensures, on the one hand, good adhesion of the adhesive bond on both sides (in case the sub-recesses 411, 421 are too deep), and on the other hand that the arrangement consisting of the fitting 30 and the assembly element 50 is pressed The process does not press itself into the outer surfaces of the sub-panels 41, 42 (in the case where the sub-recesses 411, 421 are too shallow). The method described in connection with FIG. 2 is performed with the inserted fitting 30 or fitting sample, since the proper position of the assembly element 50 results in the step of pressing the two sub-panels 41 , 42 .

It should be noted that, alternatively or additionally, the surface of the assembly element 50 may also have a structured surface. In this case, the applied adhesive layer 60 , which can then have a uniform thickness, can also compensate for tolerances, since excess adhesive can escape into the structured surface of the assembly element 50 . The same applies if the surfaces of the sub-recesses 411 , 421 to be joined are structured.

FIG. 10 shows the inserted state of the fitting 30 in the assembly element 50 . Furthermore, Figure 10 shows the application of a removal tool 70 having a front handle portion 71 and two bar-shaped insertion tongues 72 extending vertically therefrom and aligned parallel to each other. Insert tongue 72 is inserted between side section 52 of mounting plate 50 and fitting 30 , rests on frame 34 and pulls latch spring 54 out of latch recess 35 . After insertion of the removal tool 70, therefore, the locking of the catch spring 54 in the catch recess 35 is released and the accessory 30 can be removed to the front in order to optionally repair or replace it.

Removal of the fitting 30 is supported by the spring element 55 visible in FIG. 3 . When the fitting 30 is inserted, the spring element 55 is tensioned, and after the latch between the latch spring 54 and the latch recess 35 is released, the spring element 55 pops out and pushes the fitting 30 forward in the removal direction until The user can easily grasp it so far.

Thus, the illustrated furniture panel 40 allows the fitting 30 to be replaced when the furniture body or furniture is assembled.

Alternatively, other materials such as plastic or light metal may be used to assemble element 50 . If plastic is used, biopolymer materials in particular can be used, which makes it easier to recycle the furniture panel 40 . The assembly element 50 can also be manufactured in several parts, wherein the latching spring 54 and the spring element 55 can each be made of an elastic spring material.

In a further development of the furniture panel 40 , the assembly element 50 can be provided with a receptacle, to which a frame-like covering can be attached, for example, which covers the edge of the fitting 30 so that the passage of the furniture panel 40 through the Front opening, the edges are not visible. The cover may be attached to the receptacle, eg by clamping, pressing, inserting or screwing.

In the embodiment shown, since the notches 411, 421 extend into the side surfaces 412, 422, the front opening of the furniture panel 40 is already present when the two sub-panels 41, 42 are connected. In alternative designs, the notches 411, 421 may be designed such that they do not extend into the side surfaces 412, 422, but material remains between the assembly element 50 and the side surfaces 412, 422 of the sub-panels 41, 42, and thus also remains On the front side of the furniture panel 40 . The assembly element 50 (optionally with the fittings 30 already inserted) is then first fully accommodated in the furniture panel 40 . In this case, the front opening is then inserted into the furniture panel 40 from the end face, in particular milled into it. For this purpose, the assembly element 50 may have a portion of a suitable machinable material, milled therein, to form a defined edge. If the edge of the fitting is provided with a cover fixed to the assembly element 50, the cover can be inserted after the opening has been milled.

As a further example, the assembly element 50 has a curved base plate 51 facing inwardly towards the fitting 30 to be inserted. When the fitting 30 is inserted into the assembling element 50, the curved portion facing the fitting is elastically deformed outwards, so that the base plate is deformed into an almost flat shape. When the assembly element is glued into the recess 411 of one of the sub-panels 41 , the pre-tensioning ensures that the fitting 30 and the assembly element 50 and the assembly element 50 and the sub-panel 41 are produced in almost clearance-free support and contact.
