Description

Method for integrating an assembly element of a movable fitting into a furniture panel and furniture panel with an integrated assembly element

Technical Field

The invention relates to a method for integrating an assembly element of a movable fitting into a furniture panel. The invention also relates to a furniture panel having an integrated assembly element for 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. The invention further relates to a furniture body or a piece of furniture having such a furniture panel.

Background

The body of furniture is usually made of furniture panels based on wood or wooden materials, such as chipboard or medium density fibreboard or high density fibreboard (MDF, HDF). Connection fittings, movable fittings or other functional fittings are used for connecting furniture panels to one another or for the articulated connection of movable furniture parts (for example doors or flaps) and are collectively referred to herein as functional parts. The fittings are typically made of plastic and/or metal materials. In particular, larger fittings are often placed on furniture panels and screwed thereon. The larger fitting then protrudes into the interior of the furniture body so that when the door or flap is closed, the larger fitting is not visible, but when the door or flap is open, the larger fitting detracts from the appearance of the furniture body and reduces the usable interior volume of the furniture body. It is also known to insert smaller fittings into holes or recesses.

Printed publication DE 202014105730U 1 describes a furniture panel with an insert from one side of the furniture panel in a material recess that can accommodate a movable fitting. The material recess may be provided with an undercut portion to secure the insert member at least in a direction perpendicular to the surface of the furniture panel. There is no further detail as to how the insert is secured to the furniture panel or the movable fitting is secured to the insert. An advantage of arranging the insert in the recess of the furniture panel is that the inserted movable fitting is wholly or partially embedded relative to the surface of the furniture panel, so that it does not project into the interior of the furniture panel or projects into the interior of the furniture panel only to a small extent. However, the movable fitting is also visible on at least one side of the furniture panel and prevents the side of the furniture panel from being uniform with respect to visibility and in terms of material and composition.

The document DE 102017104170 a1 of the applicant, which is subsequently published, describes a furniture panel in which the box-like fittings are integrated such that the side surfaces of the furniture panel are substantially flat. To this end, the furniture panel is assembled from two sub-panels separated along a central plane, wherein a recess with a mirror-inverted contour is made in the two sub-panels, for example milled into the sub-panels, which recess forms a cavity into which the fitting is inserted, for example glued, when the furniture panel is assembled. In this case, the sides of the furniture panel are not affected by the fittings in terms of their appearance, surface finish and/or material.

Disclosure of Invention

It is an object of the present invention to provide a furniture panel with integrated assembly elements, wherein the side surfaces of the furniture panel are not affected by the movable fittings in terms of their appearance, surface finish and/or material, and still the movable fittings can be replaced.

This object is solved by a furniture panel and a method for manufacturing a furniture panel having the features of the respective independent claims. Advantageous embodiments and further developments are the subject matter 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 that a recess extends in at least one sub-panel from a side surface of the sub-panel and at least one end surface of the furniture panel, and that the recess is directed towards at least one other sub-panel, wherein at least the side walls of the assembly element are connected to opposite surfaces of the recess in a force-fitting or material-bonding manner, and the assembly element has means for fixing a movable fitting. The movable fitting can thus be inserted substantially completely into the furniture panel, wherein the movable part of the movable fitting can be moved out of one end face of the furniture panel.

With this assembly element, the movable fitting can be inserted through the front opening in the furniture panel and removed again if necessary. The assembly element is already integrated into the furniture panel during the manufacturing process of the furniture panel. By assembling two sub-panels into a furniture panel, the recess accommodating the assembly element can be inserted into a large area from one side of the sub-panel. This creates a recess which can also accommodate correspondingly large assembly elements for large movable fittings, for example 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 understood to mean that any slight projection of the movable fitting relative to the end face of the furniture panel is so small that the closing of the furniture body or the piece of furniture by means of the movable furniture part (door, flap, front panel, etc.) is not impaired. Possible protrusions are preferably less than about 1-3 millimeters (mm). This size protrusion is usually within the existing gap width between the furniture body and the movable furniture part, or can be compensated for by a narrow side coating (e.g. edge banding). It is also understood that the fitting is (only) in its retracted state within the furniture panel, wherein the movable furniture part closes the furniture body. When the furniture part is opened, an extension part of the movable fitting, for example a lever mechanism, projects above the end face.

In an advantageous embodiment of the furniture panel, the recess is introduced into one of the sub-panels, while the other sub-panel is formed in a planar manner and is free of recesses. Alternatively, a (partial) recess is provided in both sub-panels, which together form a recess after connecting the sub-panels together. The sub-recesses may be mirror symmetric, but need not be.

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

In a further advantageous design of the furniture panel, the recess has a constant depth over its surface. This is an easy to produce form of the recess, especially when milling (sub-) recesses. In principle, however, other shapes are also possible, for example a recess 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 the other regions. The depth of the recess may be at least 14mm, for example, and the thickness of the material of the furniture panel remaining in the region of the recess may be between about 1mm and 10 mm.

In a further advantageous embodiment of the furniture panel, the assembly element is glued into the recess by a material bond. Gluing can be space-saving and can also be performed in the area of the recess if the remaining material thickness of the furniture panel is small. If the side walls of the assembly element are glued to the furniture panel over the entire surface or almost the entire surface, the material thickness of the furniture panel in the region of the recess can be particularly small, so that a mounting space of maximum depth is created for the movable fitting.

Alternatively or in addition to gluing, the side wall may have a plurality of shaped elements, for example spikes, which may be pressed into the opposite surfaces of the recess and may also establish a stable connection.

In a further advantageous embodiment of the furniture panel, the end faces thereof are provided with recesses having a narrow side coating, for example 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 a further advantageous embodiment of the furniture panel, the assembly element has inwardly curved side walls which deform into almost flat side walls when the movable fitting is inserted, so that a firm contact between the side walls of the assembly element and the recess in one of the sub-panels is ensured due to the pretensioning during the gluing process.

In a further advantageous embodiment of the furniture panel, a guide, in particular in the form of a guide web, is arranged or formed on the assembly element, which guide enables the movable fitting to be inserted parallel to the side wall of the assembly element. The guide may be arranged or formed on the side wall, but may also be arranged on any existing side section projecting perpendicularly from the side wall. The guide allows the movable fitting to be inserted from the front side.

Preferably, latching means are provided by which the movable fitting engages with the assembly element. The latching means may preferably be a latching 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 fitting can optionally be removed again for repair or maintenance or replacement.

In a further advantageous embodiment of the furniture panel, the assembly element is made of a metal material, wherein the modulus of elasticity of the metal material is at least ten times higher than the modulus of elasticity of the furniture panel material or the furniture panel composite. This large difference in the modulus of elasticity (e-modulus), in particular with respect to tensile loads, makes it possible to compensate for the material weakening of the furniture panel through the recess with the relatively thin side walls of the assembly element. In this way, space is created for the movable fittings without reducing the strength or stability of the furniture panel. Typical materials or composites for furniture panels have a modulus of elasticity in the range of about 1000 to about 6500N/mm²(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 following steps: at least one recess is formed in at least one of the sub-panels. In addition, a sample of the loose fitting or non-functional fitting is inserted into the assembly member and an adhesive layer is applied to at least one side of the assembly member. The adhesive layer, at least one side of the assembly element and/or the recess has a structured surface. A device consisting of a loose fitting or non-functional fitting sample and an assembly element is inserted into a recess of one of the sub-panels and a further adhesive layer is applied to at least one side surface of the other sub-panel. The two sub-panels are joined together so that the device consisting of the loose fitting or non-functional fitting sample and the assembly element is enclosed by the two sub-panels. The furniture panel with the integrated assembly element and inserted loose fitting or non-functional fitting samples is then pressed.

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

In a further advantageous embodiment of the method, the adhesive layer has a plurality of adhesives in the form of structural elements. The structural element is, for example, a three-dimensional element, in particular a cone, a truncated cone, a cone or a truncated cone. They are preferably arranged spaced apart from one another such that after the adhesive layer has been applied, free spaces exist between adjacent structural elements. In order to compensate for tolerances, 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 a further advantageous embodiment of the method, there are approximately 10 to 300 structural elements per square centimeter (cm) in the adhesive layer. In the numbers mentioned, the structural elements can be easily formed at a typical suitable viscosity of the adhesive in the range of 15,000mPas (millipascal seconds), and they retain their shape until pressed. If the adhesive is too viscous when applied and/or the number per unit area of the structural element is too high, a deformation of the structural element for tolerance compensation is not possible or only incomplete. If the viscosity or the number per unit area is too low, the structural element will run and no tolerance compensation can be performed either.

In a further advantageous embodiment of the method, the adhesive layer has a thickness of 50g/m²To 350g/m²(grams per square meter) and preferably between 150g/m²To 250g/m²In the meantime. The adhesive may be applied by a preferably structured roller.

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

Detailed Description

Throughout the drawings, the same reference numerals indicate elements having the same or similar functions. For purposes of clarity, not every component may be labeled in every drawing.

In the specification, terms such as upper, lower, left, and right are exclusively referred to exemplary representations selected in the respective drawings. The terms "front" and "rear" refer to the direction of the furniture body, wherein the front side represents the open side of the furniture body that generally faces the user.

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

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

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

The movable fittings 30 (also referred to below as fittings 30) are arranged (apart from the lever mechanism 33, which extends in the shown open position) within the respective side walls 13 of the assembly element 50, the assembly element 50 being integrated into the side walls 13. When flap 21 is closed, lever mechanism 33 is fully retracted into side wall 13, optionally with the exception of assembly elements for connection with flap 21. The area of the fitting 30 within the side wall 13 is shown in phantom in fig. 1.

The side wall 13 is characterized in that the side surface is desirably formed in an integral manner and may have a uniform surface texture over the entire surface. The surface of the one-piece side may be designed using different patterns, surface textures, or different colors. Preferably, this applies both to the outside of the side surface and to the inside of the side surface facing the inside of the furniture body 10. The side wall 13 furthermore has an end face which has an opening in the region of the fitting 30, into which opening the lever mechanism 33 of the fitting 30 enters or from which the lever mechanism 33 exits. In the closed state of the flap arrangement 20, the lever arrangement 33 is completely immersed in the opening, except for any fastening means by which it is connected to the flap 21, which is here of 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 producing a furniture panel 40 with an integrated assembly element 50 accommodating a fitting 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 in the sub-panels 41, 42 in a mirror image to each other. When the sub-panels 41, 42 are placed on top of each other, the

recesses

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

sub-recesses

411, 421 below, since each recess only partially accommodates the combination of assembly element and fitting 30.

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

In the example shown, the fitting 30 is box-shaped and has two

parallel side plates

31, 32 separated by a frame 34. Components of the fitting 30, such as the telescopic lever mechanism 33 shown in fig. 1, are attached to the

side plates

31, 32 by rivets or other fastening elements. This is done so that the

side plates

31, 32 are as flat as possible, in particular so that the fixing elements used do not project beyond the

side plates

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 forms a housing of the fitting 30 together with the

side plates

31, 32.

On the upper and lower sides, which are not visible here, the frame 34 is slightly offset inwardly with respect to the

side plates

31, 32, so that a U-shaped guide profile is formed in each case.

In order to fix the fitting 30 in the assembly element 50, guide webs 53 are arranged on the lower and upper side sections 52, respectively. When the fitting 30 is inserted, the

side plates

31, 32, which project slightly upwards or downwards, surround the sides of the guide web 53, thus fixing 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 (viewed in the insertion direction of the fitting 30) is an inwardly projecting latching spring 54, with which the fitting 30 engages in the inserted state. For this purpose, a latching recess 35 is arranged in the frame 34 at a suitable location, into which latching recess 35 a latching spring 54 engages, so that the fitting 30 is not only secured laterally by the guide web 53, but also with respect to the insertion direction and is no longer readily advanced. Furthermore, a spring element 55 is arranged on the rear side section 52 of the assembly element 50, viewed in the insertion direction, the function of which is explained below in connection with fig. 10.

As described in more detail in connection with fig. 10, it is possible according to the present application to remove the fitting 30 from the assembly element 50 and to reinsert the fitting 30 even if the furniture panel 40 has been completely assembled. For this purpose, in an alternative embodiment 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, which fitting sample is removed after the method has been completed. The external dimensions of the fitting sample should be the same as the fitting 30 to be inserted later.

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

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

In fig. 5, an adhesive layer 60 on a 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, which here have the shape of truncated pyramids. A preferred regular arrangement of structural elements 61 is formed by an adhesive layer 60 on the substrate 51. The density of the structural elements 61 is, for example, about 10 to 300 elements/cm²Within the range of (1).

Note that instead of forming the structural elements 61 as truncated pyramids, other three-dimensional geometries may be used, such as truncated cones or cylindrical or drop-like structures. It is also possible to apply the adhesive in linear structural elements extending in one direction. It is also conceivable that the adhesive layer 60 consists of a continuous adhesive layer and applied structural elements. It is important here that the height of the adhesive layer 60 is not the same over the wetted surface, i.e. no layer with a uniform layer thickness is applied.

The adhesive used in the adhesive layer 60 is preferably an adhesive with a high viscosity that retains the illustrated structure after application and that ideally does not lose the structure due to the weight of the arrangement itself, even if the arrangement has been inserted into the sub-panel 41 from the assembly element 50 and the fitting 30. The adhesive layer 60 is applied, for example, by a structured roll forming the structural elements 61. The amount of the binder used may be 50g/m²To 350g/m²(g/m) preferably in the range of 150g/m²To 250g/m²Within the range of (1).

The viscosity of the adhesive at processing temperature (e.g., 120 ℃) is about 15,000mPas (millipascal-seconds). If the adhesive is too viscous during application, a deformation of the structural element 51 for tolerance compensation is not possible or only incompletely takes place. If the viscosity is too low, the structural element 51 will run and tolerance compensation is not possible either.

The preferred adhesive is a reactive polyurethane hot melt. 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, so the processing must be carried out within the so-called "open time" of the adhesive. In principle, the described method can also be carried out with other types of adhesives.

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

In step S5, the first and second sub-panels 41, 42 with the interposed arrangement of assembly elements 50 and fittings 30 are bonded together, and in step S6 the resulting furniture panel 40 is pressed by applying pressure in a press, e.g. a laminator, until the adhesive layer 60 hardens.

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

The press may, for example, be designed as a punch with a forcedly guided ram, so that sliding of the sub-panels 41, 42 with respect to each other is avoided. Alternatively or additionally, it is conceivable to hold the two sub-panels 41, 42 in place during pressing, in order to prevent, in particular, the front edges from sliding relative to each other. In order to obtain an aesthetically pleasing appearance, the front edges should be flush with each other.

Fig. 7 shows the joining together of the two sub-panels 41, 42 and the assembly element 50 and the arrangement of the fitting 30, and fig. 8 finally shows the furniture panel 40 joined and pressed together. The joint between the sub-panels 41, 42 is optionally easily visible and may be used as a design element. In particular, one of the sub-panels, for example the sub-panel 41, may be composed of two or more layers, for example an outer layer of wood material (possibly laminated externally with a decorative layer) and an applied inner layer of glass, plexiglass or metal. The corresponding sub-recess 411 penetrates the inner layer and extends into the outer layer. The other sub-panel 42 is again made of a wood material with a thickness of the outer layer of the sub-panel 41. The result is a composite furniture panel 40 having an intermediate layer of glass, plexiglas or metal through which the joints between the sub-panels are laminated. If a central layer of transparent or at least translucent material is used, light can be radiated from the sides, which light propagates by internal reflection and thus emerges at the edges, which may constitute an additional design element.

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

Fig. 9a shows the maximum distance d between the substrate 51 and the attached sub-panel 41 wetted by the adhesive layer 60_max. The maximum distance d_maxMuch 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 results in the shown deformation of the structural element 61, in order to adhere the adhesive of the adhesive layer 60 to the surface of the sub-panel 41 in a well-wetted manner. If the adhesive layer 60 is hardened in the condition shown in fig. 9a, although there is a remaining distance d_maxBut there is still a bond to the carrier adhesive. Spaces 62 remain between the structural elements 61, however, this does not compromise the strength of the cured adhesive layer 60.

Fig. 9b shows when the sub-panel 41 is moved maximally towards the substrate 51 and thus at a minimum distance d from the substrate 51_minThe adhesive layer 60. For illustration, fig. 9b (and also fig. 9a) shows the original shape of the structural element 61 with a height h. In the state shown, the adhesive 63 displaced by the sub-panel 41 has been pressed into the now filled free space 62, which isNot filled in fig. 9 a. When the displaced adhesive 63 completely fills the free space 62, the smallest possible distance d between the substrate 51 and the sub-panel 41 in the adhesive layer 60 is given_min。

FIGS. 9a and 9b show the structural element 61 passing through at d_minAnd d_maxWith a variable thickness of the cured adhesive layer 60 in between, the adhesive layer 60 is able to compensate for tolerances, in particular due to (wood) machining of the sub-panels 41, 42. The large tolerance range ensures on the one hand that the adhesive bond adheres well on both sides (in the case of too deep sub-recesses 411, 421) and on the other hand that the arrangement consisting of the fitting 30 and the assembly element 50 does not press itself into the outer surface of the sub-panels 41, 42 during the pressing process (in the case of too shallow sub-recesses 411, 421). The method described in connection with fig. 2 is performed by means of 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 may then have a uniform thickness, may also compensate for tolerances, since excess adhesive may escape into the structured surface of the assembly element 50. The same applies to the case where the surface of the sub-recesses 411, 421 to be joined is structured.

Fig. 10 shows the insertion state of the fitting 30 in the assembly element 50. Furthermore, fig. 10 shows the use of a removal tool 70, which removal tool 70 has a front handle portion 71 and two strip-shaped insertion tongues 72 projecting perpendicularly therefrom and aligned parallel to one another. The insertion tongue 72 is inserted between the side section 52 of the mounting plate 50 and the fitting 30, abuts against the frame 34, and pulls the latch spring 54 out of the latch recess 35. After insertion of the removal tool 70, the locking of the catch spring 54 in the catch recess 35 is thus released, and the fitting 30 can be removed to the front in order to optionally repair or replace it.

The 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 catch between the catch spring 54 and the catch recess 35 is released, the spring element 55 springs out and pushes the fitting 30 forward in the removal direction until it can be easily grasped by the user.

Thus, the illustrated furniture panel 40 allows for the replacement of the fitting 30 when assembling a furniture body or piece of furniture.

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

In a further development of the furniture panel 40, it can be provided that the assembly element 50 has a receptacle to which, for example, a frame-like cover can be attached, which covers an edge of the fitting 30, so that said edge is not visible through the front opening of the furniture panel 40. The cover may be attached to the receptacle, for example by clamping, pinching, inserting or screwing.

In the embodiment shown, the front opening of the furniture panel 40 is already present when the two sub-panels 41, 42 are connected, since the

recesses

411, 421 extend into the side surfaces 412, 422. In an alternative design, the

recesses

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 on the front side of the furniture panel 40. The assembly element 50 (optionally with the fitting 30 already inserted) is then first accommodated completely 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 in which milling is performed to form a defined edge. If the edges of the fitting are provided with a cover which is fixed to the assembly element 50, the cover can be inserted after milling the opening.

As another embodiment, the assembly element 50 has a curved base plate 51 facing inwards towards the fitting 30 to be inserted. When the fitting 30 is inserted into the assembly member 50, the bent portion facing the fitting is elastically deformed outward, so that the base plate is deformed into an almost flat shape. When gluing the assembly element into the recess 411 of one of the sub-panels 41, the pretensioning ensures that a virtually play-free support and contact of the fitting 30 with the assembly element 50 and of the assembly element 50 with the sub-panel 41 is produced.
