Description

Technical Field

[0001] This invention relates to a furniture accessory for movably mounting a first furniture component onto a second furniture component, wherein the furniture accessory has at least one panel member made of sheet metal, particularly a connecting piece, the at least one panel member having two surfaces spaced apart from each other by the material thickness of the sheet metal. The invention also relates to a piece of furniture having at least one first furniture component and at least one second furniture component, wherein the furniture includes at least one such furniture accessory. The invention further relates to a method for manufacturing at least one such furniture accessory, wherein the furniture accessory is preferably at least one pull-out guide, flip-up accessory, or hinge. Background Technology

[0002] Common furniture fittings are known in the prior art, wherein such commercially available furniture fittings are formed from boards with a defined material thickness.

[0003] Firstly, the drawback of the prior art is that it is impossible to reduce material thickness without compromising the stability of furniture fittings, thereby increasing the risk of breakage during handling and / or assembly. Since insufficient material thickness is undesirable, the resulting increase in the weight of furniture fittings leads to various problems—such as increased production costs, environmentally harmful material quantities, and / or increased transportation resources. Furthermore, from a processing technology perspective, reducing material thickness is desirable, especially in cases involving fine geometries.

[0004] Secondly, a drawback of the prior art is that it generates undesirable noise when operating known furniture fittings. Due to insufficient sound attenuation characteristics, sound is reflected unimpeded by the furniture fittings and / or transmitted substantially unimpeded through the extension of the furniture fittings.

[0005] Thirdly, the drawbacks of existing technologies are that when there are particularly high requirements for furniture fittings, such as when connecting them to heavy furniture components that need to be moved, the weight of the fittings increases significantly due to the necessary rigidity, resulting in inefficient resource utilization and making the fittings difficult to process. Using a large number of furniture fittings is an inadequate alternative that cannot solve the problem and is virtually impossible to implement in the presence of a large amount of furniture. Summary of the Invention

[0006] Therefore, the objective technical objective of this invention is to provide an improved furniture accessory compared to the prior art, as well as a piece of furniture and a method for manufacturing such a furniture accessory, wherein at least partially eliminating the disadvantages of the prior art, and its features particularly include: increasing the stability and strength characteristics of the furniture accessory, reducing the weight of the furniture accessory, and / or improving the sound attenuation characteristics of the furniture accessory.

[0007] Therefore, according to the present invention, the two surfaces are defined as follows: the two surfaces have at least one regularly arranged structure formed by successive protrusions and depressions, wherein a protrusion on one of the two surfaces is opposite to a depression on the other of the two surfaces, and vice versa.

[0008] This allows for the following: at the same material thickness, greater stability, particularly higher stiffness, load-bearing capacity, flexural strength, and torsional strength, can be ensured by using a geometry different from that of a smooth surface. When forces are transmitted to at least one sheet metal member, the forces can be absorbed in a particularly advantageous manner by using a geometry different from that of a smooth surface, especially by increasing the drag torque. Given certain requirements for at least one sheet metal member, this allows for a reduction in the material thickness of that member.

[0009] On the other hand, the maximum requirement for at least one sheet metal component can be increased because, for example, in the case where the maximum material thickness is reached due to processing technology, more weight can be absorbed by at least one sheet metal component through recesses and protrusions, while the weight of at least one sheet metal component remains unchanged. Furthermore, by reducing the weight of at least one sheet metal component, more sheet metal components can be transported and resources such as materials, costs, and / or CO2 in production can be saved.

[0010] Furthermore, an advantageous feature is that, through the surface structure achieved by the protrusions and recesses, sound is largely absorbed by at least one sheet metal member by at least one regularly arranged structure and transmitted within a small range, thereby reducing sound reflection and / or generation. Additionally, it enhances the aesthetics of at least one sheet metal member.

[0011] By using surface structures—due to at least one regularly arranged structure—material and weight savings can be generally achieved in various types of furniture fittings (e.g., furniture hinges, furniture flaps, furniture accessories, furniture guides, and / or component assemblies of furniture fittings) by reducing material thickness at the same strength and / or increasing strength at the same material thickness, with particular enhancement of acoustic and visual properties.

[0012] Before and / or after any possible bending and / or embossing steps, a regular arrangement structure—partially or completely—can be incorporated into at least one sheet metal part, for example, by embossing, rolling, and / or profiliering. Generally, the regular arrangement structure can be formed in at least one sheet metal part by superimposing to form corrugations and / or profiliering.

[0013] Additional strengthening effects can be achieved by expansion of at least one sheet metal part through at least one regularly arranged structure, wherein the neutral axis can be extended in the forming of at least one sheet metal part, for example, by using existing sheet metal bending machines and / or by not requiring cuts or unilateral recesses in the surface of at least one sheet metal part to form at least one regularly arranged structure.

[0014] As stated at the beginning, protection is also sought for a type of furniture having at least one first furniture component and at least one second furniture component, wherein the furniture includes at least one such furniture accessory: at least one first furniture component is preferably movably mounted on at least one second furniture component via the furniture accessory.

[0015] This reduces the number of furniture fittings required for movement and / or installation of furniture components, and improves the appearance of the furniture. Furthermore, heavier furniture components with fittings of a given material thickness—especially the maximum material thickness—can be used in the furniture.

[0016] As stated at the beginning, protection is also claimed for a method of manufacturing at least one such furniture accessory, preferably at least one pull-out guide, flap accessory, or hinge, characterized by steps preferably performed sequentially in a given order:

[0017] - Provide at least one flat plate.

[0018] - In at least one sub-region of the at least one plate, at least one regularly arranged structure consisting of successive protrusions and recesses is formed on two surfaces spaced apart from each other by the material thickness of the plate, wherein a protrusion on one of the two surfaces is opposite to a recess on the other of the two surfaces, and vice versa.

[0019] - The at least one sheet is formed into at least one component of the furniture fitting to be manufactured by at least one bending, stamping, cutting, coating and / or embossing step.

[0020] This method is particularly flexible in manufacturing at least one furniture accessory because, for example, after forming microstructures by protrusions and indentations, areas can be stamped out from the sheet metal, which can also be achieved by setting up a stamping press for commercially available furniture accessories. The sheet metal can then be bent into the desired geometry and further stamping can be performed by the stamping press, wherein embossed portions can be formed in the existing microstructure of the sheet metal at any point in time.

[0021] It also claims the application of forming at least one regularly arranged structure of successive protrusions and recesses on two surfaces of at least one panel piece made of sheet metal, spaced apart by the material thickness of the sheet metal, to at least partially enhance the stiffness and / or sound attenuation of the furniture fitting, said at least one panel piece being particularly a tab, wherein a protrusion on one of the two surfaces is opposite to a recess on the other of the two surfaces, and vice versa.

[0022] Furniture accessories with raised and recessed features are designed to be particularly user-friendly, increasing ease of use.

[0023] According to the invention, the at least one regularly arranged structure extends in a first direction and at least in a second direction transverse to the first direction, such that a first protrusion in the first direction and a second protrusion in the second direction are provided adjacent to a recess, and the at least one sheet metal part has at least one stamped portion.

[0024] In this way, at least one panel component has a flat, regularly arranged structure, thereby allowing for a particularly effective reduction in material thickness while maintaining the same stability and / or strength. Furthermore, the visual and acoustic properties of the furniture fittings are particularly positively affected.

[0025] It has proven particularly advantageous that the neutral axis of at least one sheet metal part undergoes bidirectional plastic deformation such that the neutral axis deforms through at least one regularly arranged structure—preferably symmetrical, substantially sinusoidal, and / or alternating—in both the direction of the first surface and the direction of the second surface.

[0026] Advantageously, it is specified that on each surface, the extreme values ​​of the protrusions and recesses of the at least one regularly arranged structure are set on imaginary lines arranged substantially parallel to each other, preferably, the protrusions and recesses of the first line are offset from the protrusions and recesses of the second line directly adjacent to the first line by half the distance between two protrusions or recesses.

[0027] This geometric arrangement of protrusions relative to depressions particularly enhances material-specific properties, such as bending stiffness, to a particularly high degree by utilizing drag torque.

[0028] It has proven advantageous that the protrusions and / or recesses of the at least one regularly arranged structure are substantially formed in the shape of a pyramid, cone, truncated pyramid, or truncated cone. However, in general, the shape of the protrusions and / or recesses is arbitrary.

[0029] According to an advantageous embodiment of the invention, the material thickness of the plate is substantially the same over the entire area of ​​the at least one regularly arranged structure.

[0030] If the difference in edge material thickness between the extremes and sides of the protrusions and / or recesses caused by the stretching process in the forming process step during, for example, rolling, embossing and / or forming processes of at least one regularly arranged structure is ignored, then at least one sheet metal part may have a substantially constant material thickness.

[0031] It has been proven advantageous that the at least one sheet metal part has at least one embossed portion extending over at least two protrusions and / or recesses of the at least one regularly arranged structure.

[0032] Imprinted sections with different functions are generally not affected by at least one regular structure and / or can use characteristics that reduce noise and increase rigidity.

[0033] An advantageous variant is that the at least one regularly arranged structure consisting of successive protrusions and depressions has at least one period.

[0034] For example, a protrusion can be followed by a depression in each of two directions; however, a regular arrangement of structures is not limited to a specific periodicity in the order of protrusions and depressions.

[0035] Particularly preferably, the thickness of the material of the plate is between 0.3 mm and 2.5 mm, preferably between 0.4 mm and 2.0 mm, and particularly preferably 0.5 mm or 0.7 mm.

[0036] According to one embodiment of the present invention, it is specified that: on two surfaces, at least three protrusions, preferably adjacent to each other, each have an extreme value, each extreme value being disposed on a common plane, wherein the normal distance of the plane is greater than the material thickness of the plate by 0.1 mm and 1.0 mm, preferably between 0.2 mm and 0.4 mm.

[0037] According to a preferred embodiment of the invention, the following is specified: two directly successive protrusions and / or depressions on one of the two surfaces have a distance between 1.6 mm and 21.0 mm, preferably between 2.0 mm and 10.0 mm, and particularly preferably between 3.5 mm and 6.5 mm.

[0038] It has been proven advantageous that on two surfaces, at least three preferably adjacent protrusions each have an extreme value, each of which is set on a common plane having a normal distance, and two directly successive protrusions and / or depressions on one of the two surfaces have a distance, wherein the distance is 2 to 8 times, preferably 3 to 7 times, and particularly preferably 4 to 6 times, the normal distance.

[0039] Preferably, it is further specified that on one of the two surfaces, at least three preferably adjacent protrusions have extreme values ​​disposed on a common plane, and at least three preferably adjacent recesses have extreme values ​​disposed on a common plane, wherein the plane has a normal distance between 0.1 and 0.6 times the material thickness of the plate, preferably between 0.2 and 0.4 times.

[0040] At least one sheet metal part can be specifically tailored to the desired characteristics by appropriately selecting the material thickness, the normal distance of the plane, the lateral extension of the protrusions and / or the extension pointing towards the surface, and the spacing between the extreme values.

[0041] Typically, protrusions and depressions can be formed differently from each other—for example, by different extensions and / or geometries; particularly preferably, protrusions and depressions are formed to be identical and / or symmetrical.

[0042] Alternatively, the at least one regularly arranged structure may

[0043] - In the at least one sheet metal component, preferably in the closing member of the furniture fitting, particularly preferably extending over more than 50%, preferably more than 75%, of the furniture fitting, or

[0044] - Extending only on at least one sub-region, preferably, the sub-region is located on the edge of the at least one panel piece and / or on the connection point of the at least one panel piece, at which the at least one panel piece is connected to or can be connected to another component of the furniture fitting.

[0045] A regular arrangement of portions on at least one sheet metal component allows specific areas of that component to be reinforced and / or adapted to individual needs in a targeted manner. Typically, at least one sheet metal component may also have at least one regular arrangement.

[0046] According to an advantageous embodiment of the invention, the at least one sheet metal part is provided as follows: the at least one flat surface is provided, and the at least one flat surface is not provided with the at least one regularly arranged structure.

[0047] This allows for areas where, for example, scrolling and / or sliding properties can be increased.

[0048] According to an advantageous embodiment of the invention, the at least one sheet metal member has a first acoustic attenuation in the region of the at least one flat surface, and the at least one sheet metal member has a second acoustic attenuation in the region having the at least one regularly arranged structure, wherein the second acoustic attenuation is at least 1.1 times, preferably 1.5 times, the first acoustic attenuation.

[0049] Preferably, the at least one sheet metal member has a first stiffness in the region of the at least one flat surface, and the at least one sheet metal member has a second stiffness in the region having the at least one regularly arranged structure, wherein the second stiffness is at least 1.1 times and at least 1.5 times the first stiffness.

[0050] Compared to commercially available sheet metal parts with smooth surfaces, the acoustic properties and load-bearing capacity of at least one sheet metal part can be increased by at least one regularly arranged structure.

[0051] It has proven advantageous that the at least one flat surface is formed as a running surface for a rolling element moving on the running surface, preferably, the at least one sheet metal part has a longitudinal direction, and the at least one running surface is formed as a running track oriented substantially parallel to the longitudinal direction of the at least one sheet metal part.

[0052] The presence of at least one flat surface makes it possible to particularly promote the rolling behavior of the rolling elements, wherein, for example, the rolling elements will not be misaligned due to uneven running track.

[0053] According to an advantageous embodiment of the present invention, the at least one sheet metal part is provided to have at least two geometrically different regular arrangement structures.

[0054] By employing two geometrically different regular arrangement structures, at least one sheet metal component can be equipped with regions of different characteristics—for example, with different curvatures due to varying heights from recessed extremities to raised extremities and / or specific contour shapes of the recesses and convexities.

[0055] It has proven advantageous that the at least one sheet metal part has at least one stamped portion, preferably formed for receiving at least one fixing device, and / or formed for fixing at least one furniture part, and / or formed substantially cylindrical, and / or formed for mounting at least one hinge pin, and / or for releasing at least one adjusting element of an adjusting device, thereby allowing the adjusting element to be manipulated by means of at least one tool.

[0056] An advantageous variation is that the at least one sheet metal part is disposed on the molded component of the furniture fitting, preferably the molded component being formed in at least a partial U-shape in cross-section.

[0057] Typically, at least one sheet metal component can be interlocked or detachably connected to the material of a molded component, or formed as a molded component. Sheet metal bending components with different profiles are particularly suitable for at least one regularly arranged structure.

[0058] Particularly preferably, the furniture accessory is formed as a pull-out guide, a flip-top accessory, or a hinge.

[0059] According to an advantageous embodiment of the invention, the at least one bending, stamping, cutting, coating and / or embossing step is performed after the formation of the at least one regularly arranged structure.

[0060] For example, removing a sub-region by laser can be considered a cutting step. It is also conceivable that bending, stamping, cutting, coating and / or embossing steps are performed before or after the formation of the at least one regular arrangement structure.

[0061] Advantageously, it is specified as follows: the at least one regularly arranged structure

[0062] - Formed into the at least one sub-region of the at least one sheet metal by at least one die and / or at least one roller, and / or

[0063] - It was added starting from two surfaces.

[0064] For example, different types of molds and / or punching dies and / or cold rolling methods can be used to form at least one regularly arranged structure.

[0065] It has been proven advantageous that the neutral axis of the at least one plate is extended when forming the at least one regular arrangement structure.

[0066] According to an advantageous embodiment of the invention, it is specified that when forming the at least one regular arrangement structure, the at least one sheet is stretched at least in the region where the at least one regular arrangement structure is formed.

[0067] By shaping protrusions and depressions, or through the forming process, the neutral axis is stretched and moves particularly in the bending direction.

[0068] It has been proven advantageous that, in another method step, at least one embossed portion is embossed in the at least one sheet material, the at least one embossed portion extending over at least two protrusions or recesses of the at least one regularly arranged structure.

[0069] An advantageous variation is that, when forming the at least one regular arrangement structure, at least one preferably strip-shaped surface of the at least one plate is left with a gap.

[0070] Particularly preferably, it is specified that: in at least one second sub-region of the at least one plate, at least one additional regular arrangement structure is formed on the two surfaces, wherein the at least one additional regular arrangement structure is geometrically different from the at least one other regular arrangement structure.

[0071] And particularly preferably, the at least one component of the furniture fitting to be manufactured is connected to at least one other component in a further method step, for example by gluing, riveting, self-riveting, brazing and / or fusion welding, and / or the furniture fitting is equipped with at least one drive device and / or at least one buffer in a further method step.

[0082] Figure 10a The plan view, showing a detailed cross-section, illustrates a sheet metal with a regularly arranged structure used in a furniture fitting in the form of a pull-out guide according to another preferred embodiment. Prior to the bending process, it has two running surfaces, an embossing section, and a stamping section.

[0083] Figure 10b The top view is shown in accordance with Figure 10a The bending process of the sheet metal and the furniture accessories after the additional stamping. Detailed Implementation

[0084] Figures 1a to 4b The illustrated furniture accessory 1 is not designed according to the present invention, wherein the regular arrangement structure 9 consisting of protrusions 10 and recesses 11 is absent. The regular arrangement structure 9 can be used in all existing sheet metal parts 5 to improve the corresponding furniture accessory 1 in terms of stability, strength, weight, transport, acoustics, and visual characteristics.

[0085] Figure 1a The illustration shows a furniture accessory 1 in the form of a pull-out guide 33, which has numerous embossed portions 16 and stamped portions 29 formed in the component 20. The furniture accessory 1 includes four sheet metal pieces 5 in the form of interlocking pieces, which are formed by a bending process of sheet metal 4.

[0086] Figure 1b and Figure 1a The difference lies in the fact that, when viewed from the side, the guide 33 is pulled out. Each of the four sheet metal parts 5 has two surfaces 7 and 8, which are separated from each other by a material thickness 6.

[0087] Figure 2a The perspective view illustrates the arrangement of a drawer pull-out guide 33 and a drawer sidewall 38. The fixing sections 39 and 40 of the first guide rail 41 each have one or more fixing points 42 and 43 for securing to the furniture body. The third guide rail 44 is connected to or releasably connected to the drawer sidewall 38, wherein the second guide rail 45 is movable between the first guide rail 41 and the third guide rail 44.

[0088] A coupling element 46 is provided on the first guide rail 41, which can be releasably coupled to the drive element 47 of the retraction device 48 supported on the third guide rail 44, such that the third guide rail 44 is gripped by the drive element 47 at the end of the closing movement and can be retracted to the closed terminal position by the accumulator of the retraction device 48. This spring-assisted retraction movement of the third guide rail 44 is buffered by a buffer 49 (preferably having a hydraulic piston-cylinder unit) until the closed terminal position is reached.

[0089] The drawer sidewall 38 is designed as a hollow profile, the hollow profile having an inner profile wall 50 and an outer profile wall 51 spaced apart from the inner profile wall 50. The drawer sidewall 38 forms a channel 52 that opens downwards and extends longitudinally within the channel 52, in which a third guide rail 44 can be installed. The drawer sidewall 38 also includes: a first fixing device 53 for connection to the rear wall, a second fixing device 54 for connection to the front trim panel, and a support member 55 for supporting the bottom of the drawer.

[0090] Figure 2b The diagram illustrates a first guide rail 41 with fixed sections 39 and 40 to be assembled onto the main body of the furniture. The first guide rail 41 has a U-shaped or C-shaped section in cross-section, in which a carriage 56 is movably supported and a separate carriage 57 for guiding and supporting a second guide rail 45. The carriage 56 and the separate carriage 57 are movably mounted in a common running surface 26. The carriage 56 has load-transmitting rollers 27, whose axes of rotation are spaced apart in the height direction and thus disposed in separate running surfaces 26. The carriage 56 also has lateral support rollers 57, which have axes of rotation extending vertically in the assembled position. The lateral support rollers 57 are movable on one hand along a vertically extending tab of the first guide rail 41 in the longitudinal direction (L), and on the other hand along a vertically extending tab of the second guide rail 45. By providing or forming teeth 58 on the carriage 56, the movement of the carriage 56 can be synchronized with the movement of another carriage 56, which is slidably supported between the second guide rail 45 and the third guide rail 44.

[0091] Figure 3a The furniture accessory 1 shown is in the form of component 20, which is configured as a flip-top accessory 34. The stamped portion 29, extending through the material thickness 5 in surfaces 7 and 8, is configured to accommodate the fixing device 30 and is cylindrical, wherein a hinge pin can be supported on the stamped portion 29.

[0092] Figure 3b and Figure 3a The only difference is that the furniture accessory 1 is shown in a side view. The flip-top accessory 34 has three panel pieces 5, on which a regular arrangement structure 9 can be introduced.

[0093] Figure 4a The illustration shows a furniture accessory 1 designed as a hinge 35. The furniture accessory 1 has a stamped portion 29 that releases the adjusting element 31 of the adjusting device 32, so that the adjusting element 31 can be manipulated by means of a tool.

[0094] Furniture accessory 1 is configured to realize movable support of a first furniture component on a second furniture component, wherein furniture accessory 1 has a plate component 5 made of plate 4, which is configured to be in the form of a splice.

[0095] Figure 4b and Figure 4a The only difference is that: the previous view shows furniture accessory 1. It is conceivable that a regular arrangement structure 9 is introduced into the three board pieces 5 before or after the bending process of the board 4 of furniture accessory 1, wherein, particularly preferably, the regular arrangement structure 9 is introduced before the bending process.

[0096] Figure 5 The diagram illustrates a sheet material 4 with two surfaces 7 and 8, spaced apart by a material thickness 6. The surfaces 7 and 8 have a regularly arranged structure 9 (schematically illustrated) formed by successive protrusions 10 and recesses 11. A protrusion 10 on one surface of the two surfaces 7 and 8 is opposite to a recess 11 on the other surface of the two surfaces 7 and 8, and vice versa. The material thickness 6 of the sheet material 4 is (non-limitingly) chosen to be 0.5 mm.

[0097] The neutral axis 36 is schematically drawn as a dashed line relative to the reference plane of the protrusion 10 and the depression 11 (determined by the introduction of the regular arrangement structure 9).

[0098] Figure 6a The figure shows a three-dimensional design of a regularly arranged structure 9, wherein the regularly arranged structure 9 extends in a first direction 12 and a second direction 13 transverse to the first direction 12, thereby providing a first protrusion 10 on the first direction 12 and a second protrusion 10 on the second direction 13 adjacent to a recess 11.

[0099] On each surface 7, 8, the extreme values ​​14 of the regularly arranged protrusions 10 and recesses 11 of the structure 9 are set on imaginary lines arranged parallel to each other. The protrusions 10 and recesses 11 of the first line are arranged to be offset relative to the protrusions 10 and recesses 11 of the second line directly adjacent to the first line by half the distance 19 between two protrusions 10 or recesses 11. Therefore, the two-dimensional wave structure is particularly advantageous for increasing bending stiffness.

[0100] The regularly arranged protrusions 10 and recesses 11 of the structure 9 are determined by the sharp protrusions of the pressing rollers or punches. The protrusions 10 and recesses 11 are formed into truncated pyramids, and their radius of curvature depends on the material thickness 6. Typically, they can also be formed into pyramids, cones, or truncated cones.

[0101] On the two surfaces 7 and 8, three adjacent protrusions 10 have extreme values ​​14, which are respectively set on a common plane 17, wherein the normal distance 18 of the plane 17 is increased by a regularly arranged structure 9 compared to the material thickness 6. In this embodiment, the increase in material thickness by the protrusions 10 and the recesses 11 is selected to be 0.2 mm.

[0102] On one of the two surfaces 7 and 8, two directly successive protrusions 10 and recesses 11 are spaced 3.5 mm apart, however, the distance 19 can be adjusted according to the requirements of the furniture fitting 1.

[0103] Figure 6b The diagram shows the surface structure of the regularly arranged structure 9, where the lower contours of the protrusions 10 and the recesses 11 are represented by dashed lines. It can be seen that the material thickness 6 of the plate 4 is the same or constant throughout the entire area of ​​the regularly arranged structure 9 (ignoring the plastic deformation between the extreme values ​​14 of the protrusions 10 and the recesses 11 and the side).

[0104] Two directly successive protrusions 10 and recesses 11 are spaced 19 on one of the two surfaces 7 and 8, wherein the distance 19 is chosen to be five times the normal distance 18.

[0105] The plane 17 between the extreme values ​​of the protrusion 10 and the extreme value 14 of the depression 11 has a normal distance 18', which is 0.2 times the material thickness 6 of the plate 4.

[0106] Figure 7 The diagram illustrates a board 4 used to manufacture furniture fitting 1, wherein a regular arrangement structure 9 formed by successive protrusions 10 and recesses 11 is periodic. The periodicity is a two-dimensional alternation of protrusions 10 and recesses 11 (similar to a sine wave structure).

[0107] The stamping part 29 and / or the embossing part 16 may be performed before and / or after the bending process to form the component 20.

[0108] Figure 8 The diagram shows the pull-out guide 33, in which, in a detailed cross-section, it can be seen that the sheet metal part 5 has an embossed portion 16 that extends over a plurality of protrusions 10 and recesses 11 of a regularly arranged structure 9.

[0109] Typically, different panel components 5 may have different regular arrangements 9, which have specific geometric shapes. It is also conceivable that there may be varying regular arrangements 9 within the panel component 5, which may differ, for example, in terms of periodicity, distance 19, and / or normal distances 18, 18'. The regular arrangements 9 extend over 100% of the furniture fitting 1.

[0110] Figure 9a The illustrated panel 5 is mounted on the molded component of the furniture accessory 1, wherein the molded component is partially U-shaped in cross-section. A regularly arranged structure 9 in the form of protrusions 10 and recesses 11 is visible on the two surfaces 7 and 8.

[0111] Figure 9b and Figure 9a The only difference is that the guide 33 is pulled out in a top view. The cross-section of the surface structure of the regularly arranged structure 9 shows that the sheet metal part 5 has a stamped part 29 and is mainly configured as a fastener 30 for furniture components.

[0112] Figure 10a The diagram illustrates a panel 4 with a regular arrangement structure 9, which extends over extensive sub-regions. Typically, these sub-regions may also be located only on the edges 22 of the panel 5 and / or on the connection points 23 of the panel 5, where the panel 5 is connected to or can be connected to other components 24 of the furniture fitting 1.

[0113] In this embodiment, the sheet material 4 has two flat surfaces 25 without a regular arrangement structure 9, and the sheet material 4 includes a sheet component 5 after the bending process.

[0114] The following are exemplary method steps for manufacturing furniture accessory 1:

[0115] - Provides flat panels 4 without a regular arrangement structure 9.

[0116] - In the plate 4, at least one regularly arranged structure 9, formed by successive protrusions 10 and recesses 11, is added to two surfaces 7 and 8 that are spaced apart from each other by the material thickness 6 of the plate 4, wherein a protrusion 10 on one of the two surfaces 7 and 8 is opposite to a recess 11 on the other of the two surfaces 7 and 8, and vice versa.

[0117] - At least one regularly arranged structure 9 is incorporated into the sheet 4 from two surfaces 7, 8 by means of a die and / or two rollers, wherein, when at least one regularly arranged structure 9 is formed, the neutral axis 36 of the sheet 4 is elongated, and the sheet is stretched in the region where at least one regularly arranged structure 9 is incorporated, and

[0118] - The sheet material 4 is formed into a component 20 of the furniture fitting 1 to be manufactured through bending, stamping, cutting, coating and / or embossing steps.

[0119] Typically, bending, stamping, cutting, coating and / or embossing steps can be performed after or immediately following the addition of at least one regularly arranged structure 9.

[0120] In another method step, an embossed portion 16 may be embossed in the sheet material 4, which extends on a plurality of protrusions 10 or recesses 11 of at least one regularly arranged structure 9.

[0121] In this embodiment of the invention, when the regularly arranged structure 9 is added, the two strip surfaces of the plate 4 are left with gaps so that the two strip surfaces can be used as running tracks for the rolling element 27.

[0122] In the presence of multiple regularly arranged structures 9, the regularly arranged structures 9 are geometrically different from each other.

[0123] In further steps of the process, component 20 may be connected to other parts, for example by gluing, riveting, self-riveting, brazing, and / or welding. Drive mechanisms, dampers, and / or similar devices may also be provided to expand the functionality of furniture accessory 1.

[0124] Figure 10b The illustration shows furniture fitting 1 as a pull-out guide 33, wherein the panel component 5 has a first sound attenuation in the area of ​​the flat surface 25, and the panel component 5 has a second sound attenuation in the area with a regular arrangement structure 9, wherein the second sound attenuation is 10% higher than the first sound attenuation. Similarly, the second stiffness in the area with the regular arrangement structure 9 is 10% higher than the first stiffness in the area without the regular arrangement structure 9.

[0125] Two flat surfaces 25 are formed as a running surface 26, which is used for a rolling element 27 (see [reference]) moving on the running surface 26. Figure 2b The plate component 5 has a longitudinal direction 28, and the running surface 26 is configured as a running track oriented parallel to the longitudinal direction 28 of the plate component 5.

[0126] Furniture accessory 1 can be used in furniture having a first furniture component and a second furniture component, wherein the first furniture component is movably supported on the second furniture component by means of the furniture accessory.
