Description

[Technical field]

[0001] The present invention relates to a furniture fitting for preferably movably supporting a first furniture part on a second furniture part, the furniture fitting having at least one sheet metal piece, in particular a web, manufactured from sheet metal and having two surfaces separated from each other by the material thickness of the sheet metal.The present invention further relates to a piece of furniture comprising at least one first furniture part and a second furniture part and comprising at least one such furniture fitting.The present invention further relates to a method for manufacturing at least one such furniture fitting, preferably at least one drawer guide, flap fitting or hinge.

[0002] Furniture fittings of the type mentioned at the outset are known from the prior art, and commercially available furniture fittings of this type are made from sheet metal having a defined material thickness.

[0003] A drawback of the prior art is that, according to a first aspect, the material thickness cannot be reduced without compromising the stability of the furniture fitting and increasing the risk of breakage during operation and / or assembly of the furniture fitting. A material thickness that should not be reduced leads to various problems, such as increased costs during production, environmentally unfriendly material amounts, and / or increased transport resources required, due to the associated increase in weight of the furniture fitting. Furthermore, a reduction in material thickness is desirable from a manufacturing technology perspective, especially in the case of precise geometric structures.

[0004] A drawback in the prior art, according to a second aspect, is the generation of undesirable noise when handling the known furniture fittings, which due to insufficient sound-deadening properties are reflected unhindered from the furniture fitting and / or transmitted substantially unhindered throughout the extent of the furniture fitting.

[0005] A disadvantage of the prior art, according to the third aspect, is that when the demands on the furniture fitting are particularly high, such as for attachment to heavy furniture parts to be moved, the necessary rigidity of the furniture fitting leads to a significant increase in its weight, which leads to an inefficient consumption of resources and makes the furniture fitting difficult to handle in terms of production technology. The possibility of using several furniture fittings is an unsatisfactory option, which does not solve the problem and is, moreover, practically unrealistic when there are several pieces of furniture.

[0006] The technical problem addressed by the present invention is therefore to provide an improved furniture fitting, as well as furniture, and a method for manufacturing such furniture fitting, which at least partially overcomes the disadvantages of the prior art and which is distinguished by, in particular, increased stability and strength properties, reduced weight and / or improved sound-deadening properties of the furniture fitting.

[0007] This problem is solved by the features of claim 1.

[0008] Thus, according to the invention, both surfaces have at least one regular arrangement of mutually continuous protuberances and recesses, where a protuberance on one of the surfaces is opposed by a recess on the other of the surfaces, and vice versa.

[0009] Firstly, this makes it possible to ensure a higher stability, in particular stiffness, supportability, bending stiffness and torsional stiffness, with the same material thickness, by not providing a smooth surface. When transmitting forces to the at least one sheet piece, it is particularly preferred that the forces are absorbed by the at least one sheet piece via a geometry that is not smooth, in particular by means of an increased moment of resistance. This makes it possible to reduce the material thickness of the at least one sheet piece for a given requirement on the at least one sheet piece.

[0010] On the other hand, the maximum requirement for the at least one sheet piece can be increased, because if, for example, the weight of the at least one sheet piece remains the same under the maximum material thickness based on the manufacturing technology, more weight can be absorbed by the at least one sheet piece via the recesses and protuberances. Furthermore, by reducing the weight of the at least one sheet piece, more sheet pieces can be transported, which saves material, costs and / or resources in production, such as CO2.

[0011] Furthermore, the surface structure realized via the ridges and recesses has the advantageous property that sound is absorbed to a large extent by the at least one sheet piece via at least one ordered arrangement and transmitted to a small extent, thereby reducing the reflection and / or generation of sound. Furthermore, the aesthetic appearance of the at least one sheet piece is improved.

[0012] The surface structure resulting from at least one regular arrangement makes it possible to achieve material and weight savings in various types of furniture fittings, such as furniture hinges, furniture flaps, furniture fittings, furniture guides, and / or furniture fitting components in general, with reduced material thickness at the same strength and / or increased strength at the same material thickness, in which case, in particular, acoustic and visual properties are improved.

[0013] The ordered arrangement is - in particular partially or completely - for example applied to the at least one sheet piece by embossing, rolling and / or forming, before and / or after a possible bending or embossing step. In general, the ordered arrangement may be provided superimposed on a corrugation and / or a formed shape in the at least one sheet piece.

[0014] An additional reinforcing effect is obtained by corrugating at least one sheet piece over at least one regular arrangement, in which case the intermediate fibers can be stretched during deformation of the at least one sheet piece, e.g. existing sheet bending machines can be used, and / or for the at least one regular arrangement, it is not necessary to provide cuts or one-sided undercuts on one surface of the at least one sheet piece.

[0015] As mentioned at the outset, patent protection is also sought for furniture comprising at least one first furniture part and at least one second furniture part, which furniture comprises at least one such furniture fitting, by means of which the at least one first furniture part is preferably movably supported on the at least one second furniture part.

[0016] This allows reducing the number of furniture fittings required for moving and / or supporting the furniture parts and improves the appearance of the furniture. Furthermore, heavy furniture parts with furniture fittings of a given material thickness, especially of the maximum material thickness, can be used in the furniture.

[0017] As mentioned at the outset, a method for manufacturing at least one such furniture fitting, preferably at least one drawer guide, flap fitting or hinge, preferably comprising the following method steps, successive in time to one another, preferably in the stated order, namely: - providing at least one flat sheet metal, - machining, in at least one partial region of at least one metal sheet, on two surfaces separated from each other by the material thickness of the metal sheet, at least one regular arrangement of adjacent elevations and depressions, in which a elevation on one of the surfaces is faced by a depression on the other of the surfaces and vice versa, - forming at least one sheet metal into at least one component part of the furniture fitting to be manufactured by at least one bending, punching, cutting, coating and / or embossing step; Patent protection is also sought for a process comprising the steps of:

[0018] This method is particularly flexible in the manufacture of at least one furniture fitting, since, for example, after the formation of the microstructure with ridges and recesses, areas can be punched out of the sheet metal, which is also possible for commercially available furniture fittings by adjusting the punching machine, the sheet metal can then be bent into structures of the desired geometry, and further punching operations can be carried out by the punching machine, in which case the microstructure provided in the sheet metal can each time be provided with an embossing.

[0019] Patent protection is also sought for the use of at least one regular arrangement of adjacent ridges and recesses on two surfaces, separated from each other by the material thickness of the sheet metal, of at least one sheet metal piece, in particular a web, of a furniture fitting, in which a ridge on one of the surfaces is opposed by a recess on the other of the surfaces and vice versa, for increasing the stiffness and / or sound-deadening properties of the furniture fitting, at least in certain areas.

[0043] According to an advantageous embodiment of the invention, it is provided that at least one sheet metal piece has at least one flat surface which is not provided with at least one ordered arrangement.

[0049] At least one flat surface can ensure a particularly good rolling behavior of the rolling elements, in which case no precession of the rolling elements due to, for example, unevenness in the running track is to be expected.

[0050] According to an advantageous embodiment of the invention, it is provided that at least one sheet metal piece has at least two ordered arrangements with different geometries.

[0051] The two regular arrangements with different geometries make it possible to provide at least one thin sheet piece with areas with different properties - for example with respect to different curvatures due to variable heights from the maximum point of the recess to the maximum point of the protuberance and / or with respect to specific irregular shaped shapes of the recesses and protuberances.

[Figure 10a] FIG. 13 shows a top view and partial detail of a sheet metal with a regular arrangement for a furniture fitting in the form of a drawer guide with two running surfaces, embossed portions and punched portions according to another preferred embodiment, before bending. [Figure 10b] FIG. 10b shows a top view of the furniture fitting after bending and further stamping of the sheet metal of FIG.

[0069] 1a-4b show a prior art furniture fitting 1 configuration not according to the invention, which does not have the regular arrangement 9 of ridges 10 and recesses 11. The regular arrangement 9 can be used with all existing sheet metal pieces 5 to improve the respective furniture fitting 1 with regard to stability, strength, weight, transport properties, acoustic properties and visual properties.

[0070] Figure 1a shows a furniture fitting 1 in the form of a drawer guide 33, which comprises a number of embossments 16 and punched out portions 29 formed in a component part 20. The furniture fitting 1 comprises four sheet metal pieces 5 in the form of webs formed by a bending process of sheet metal 4.

[0071] 1b differs from FIG. 1a in that the drawer guide 33 is shown from a side view direction. The four sheet metal pieces 5 each have two surfaces 7, 8 which are separated from each other by a material thickness 6.

[0072] Figure 2a shows in perspective view an assembly including the drawer guide 33 and the drawer side wall 38 of the drawer. The mounting sections 39,40 of the first guide rail 41 have one or more mounting points 42,43, respectively, for mounting to a furniture cabinet. A third guide rail 44 is connected or removably connectable to the drawer side wall 38, and a second guide rail 45 is movable between the first guide rail 41 and the third guide rail 44.

[0073] A connecting element 46 is arranged on the first guide rail 41, which can be removably connected to a follower 47 of a retraction device 48 supported on the third guide rail 44, so that the third guide rail 44 is gripped by the follower 47 towards the end of the closing movement and can be retracted into the closing end position by means of a force accumulator of the retraction device 48. Such a spring-assisted retraction movement of the third guide rail 44 to the closing end position can be damped by a damping device 49, which preferably has a hydraulic piston-cylinder unit.

[0074] The drawer side wall 38 is configured as a hollow section with an inner profile wall 50 and an outer profile wall 51 spaced apart from the inner profile wall and defines a passage 52 that is open downwards and extends in the longitudinal direction of the drawer side wall 38, in which passage the third guide rail 44 can be arranged. The drawer side wall 38 further comprises a first attachment device 53 for connection to the back wall, a second attachment device 54 for connection to the front panel, as well as a rest 55 for supporting the drawer bottom.

[0075] 2b shows a first guide rail 41 with mounting sections 39, 40 to be attached to a furniture cabinet. The first guide rail 41 has a U-shaped or C-shaped section in cross section, in which a carriage 56 and a separate carriage 57 are slidably supported for guiding and supporting the second guide rail 45. The carriage 56 and the separate carriage 57 are slidably supported on a common running surface 26. The carriage 56 has rolling elements 27 for transmitting the load, the rotation axes of which are spaced apart from one another in the height direction and thus arranged on separate running surfaces 26. The carriage 56 furthermore has a lateral support roller 57 with a vertically extending axis of rotation in the assembled position, which lateral support roller 57 is movable on the one hand along a vertical web extending in the longitudinal direction (L) of the first guide rail 41 and on the other hand along a vertical web of the second guide rail 45. By means of a toothing 58 arranged or formed on the carriage 56, the movement of the carriage 56 can be synchronized via a gear with the movement of another carriage 57, which is slidably supported between the second guide rail 45 and the third guide rail 44.

[0076] 3a shows the furniture fitting 1 in the form of a component 20 which is formed as a flap fitting 34. A punched-out portion 29 in the surfaces 7, 8 which passes through the material thickness 5 is cylindrically shaped to accommodate the fastening means 30 and allows support of a joint pin in the recess 29.

[0077] Figure 3b differs from figure 3a only in that the furniture fitting 1 is shown from the side. The flap fitting 34 has three lath pieces 5, which may be provided with a regular arrangement 9.

[0078] FIG. 4a shows a furniture fitting 1 with a punched-out portion 29 formed as a hinge 35, which releases an adjustment element 31 of an adjustment device 32, so that the adjustment element 31 can be operated by a tool.

[0079] The furniture fitting 1 is designed to allow a movable support of a first furniture part on a second furniture part, the furniture fitting 1 having a sheet metal piece 5 manufactured from sheet metal 4, which sheet metal piece is designed in the form of a web.

[0080] Figure 4b differs from figure 4a only in that the furniture fitting 1 is shown from the front. It is conceivable to provide the three sheet metal pieces 5 with the regular arrangement 9 before or after the bending process of the sheet metal 4 of the furniture fitting 1, in which case it is particularly preferred that the regular arrangement 9 is provided before the bending process.

[0081] 5 shows a metal sheet 4 with two surfaces 7,8 separated from each other by a material thickness 6 of the metal sheet 4, where both surfaces 7,8 have a regular array 9 of (schematically shown) continuous ridges 10 and recesses 11, where a ridge 10 on one of the surfaces 7,8 is opposed by a recess 11 on the other of the surfaces 7,8 and vice versa. The material thickness 6 of the metal sheet 4 is selected to be 0.5 mm (without being limited thereto).

[0082] Intermediate fibers 36 are shown diagrammatically in dotted lines as reference planes relative to the ridges 10 and recesses 11 (resulting from the provision of ordered array 9).

[0083] Figure 6a shows a three-dimensional configuration of the ordered array 9, in this case extending in a first direction 12 and a second direction 13 transverse to the first direction 12, such that adjacent to one recess 11, one first ridge 10 is arranged in the first direction 12 and one second ridge 10 is arranged in the second direction 13.

[0084] On the surfaces 7, 8, respectively, the maxima 14 of the ridges 10 and recesses 11 of the regular array 9 are arranged on imaginary lines that are arranged parallel to one another. The ridges 10 and recesses 11 of a first line are offset by half the distance 19 between two ridges 10 or two recesses 11 with respect to the ridges 10 and recesses 11 of a second line that is directly adjacent to the first line, so that the two-dimensional wave structure results in a particularly good increase in bending stiffness.

[0085] The ridges 10 and recesses 11 of the regular array 9 are formed by pressing in sharp protrusions of a roll or punch, and in this case, the shape of the ridges 10 and recesses 11 is formed in the shape of a truncated pyramid having a predetermined radius of curvature depending on the material thickness 6. In general, the shape can also be formed in the shape of a pyramid, a cone, or a truncated cone.

[0086] On both surfaces 7, 8, three adjacent ridges 10 each have a maximum point 14 which is located in a common plane 17, the normal spacing 18 of which is increased by the regular arrangement 9 relative to the material thickness 6. In this embodiment, the increase in material thickness due to the ridges 10 and recesses 11 is selected to be approximately 0.2 mm.

[0087] The two ridges 10 and the two recesses 11 which are directly adjacent to one another on one of the surfaces 7, 8 have a spacing 19 of 3.5 mm, which can be adapted depending on the requirements imposed on the furniture fitting 1.

[0088] FIG. 6b shows the surface structure of the ordered array 9, where the contours of the undersides of the ridges 10 and recesses 11 are shown with dotted lines, which shows that the material thickness 6 of the metal sheet 4 is the same or constant over the entire area of ​​the ordered array 9 (if variable plastic deformation between the maximum points 14 of the ridges 10 and recesses 11 and the sides is not taken into account).

[0089] The two elevations 10 and the two depressions 11 which are directly adjacent to one another have a spacing 19 on one of the surfaces 7, 8 which is chosen to be five times larger than the normal spacing 18.

[0090] The plane 17 between the maximum point of the ridge 10 and the maximum point 14 of the recess 11 has a normal spacing 18 ′ that is 0.2 times the material thickness 6 of the metal sheet 4 .

[0091] 7 shows a metal sheet 4 for manufacturing a furniture fitting 1, in which the regular array 9 of successive ridges 10 and recesses 11 has a periodicity, which is formed in the form of a two-dimensional alternation of ridges 10 and recesses 11 (similar to a sinusoidal wave structure).

[0092] The stamped portions 29 and / or embossed portions 16 may be provided before and / or after the bending operation to form the component 20 .

[0093] FIG. 8 shows a drawer guide 33 where in a detailed view it is clear that the sheet metal piece 5 has an embossed portion 16 extending across a plurality of ridges 10 and recesses 11 in a regular array 9.

[0094] In general, different lamella pieces 5 may have different regular arrays 9 with specific geometries. Variable regular arrays 9 within one lamella piece 5 are also contemplated, and these regular arrays may differ, for example, in periodicity, spacing 19, and / or normal spacing 18, 18'. The regular arrays 9 extend over 100% of the furniture fitting 1.

[0095] 9a shows that the sheet metal pieces 5 are arranged on a profiled component 20 of the furniture fitting 1, which in cross section is U-shaped in certain areas. The regular arrangement 9 is evident on both surfaces 7, 8 in the form of ridges 10 and recesses 11.

[0096] Figure 9b differs from figure 9a only in that the drawer guide 33 is shown from above. The part of the surface structure of the regular arrangement 9 shows that the sheet metal pieces 5 have punched-out portions 29 and are formed inter alia as attachment means 30 for furniture components.

[0097] 10a shows a metal sheet 4 with a regular arrangement 9, which in this case extends over a localized large area. In general, the localized area may be located only at an edge 22 of the sheet metal piece 5 and / or at a joining point 23 of the sheet metal piece 5, where the sheet metal piece 5 is or can be joined to another component 24 of the furniture fitting 1.
