FURNITURE FITTING FOR STORING A PIECE OF FURNITURE

Description

[0001] The invention relates to a furniture fitting for the preferably movable mounting of a first furniture part on a second furniture part, wherein the furniture fitting comprises at least one sheet metal piece, in particular a web, made of sheet metal with two surfaces spaced apart from one another by a material thickness of the sheet metal. Furthermore, the invention relates to a piece of furniture with at least a first and a second furniture part, wherein the furniture comprises at least one such furniture fitting. Furthermore, the invention relates to a method for producing at least one such furniture fitting, preferably at least one pull-out guide, a flap fitting, or a hinge.

[0002] Furniture fittings of this type are known from the prior art, with such commercially available furniture fittings being made of sheet metal with a defined material thickness.

[0003] A disadvantage of the prior art, according to a first aspect, is that the material thickness cannot be reduced without compromising the stability of the furniture fitting to such an extent that there is an increased risk of breakage during operation and / or assembly of the furniture fitting. A material thickness that cannot be undercut causes various problems due to the associated increased weight of the furniture fitting – such as increased manufacturing costs, environmentally harmful material quantities, and / or increased required transport resources. Furthermore, reduced material thicknesses are desirable from a manufacturing perspective, particularly for delicate geometric structures.

[0004] A second disadvantage of the prior art is the undesirable noise generated during operation of the known furniture fittings. Due to insufficient sound-damping properties, sound is reflected unhindered by the furniture fittings and / or transmitted essentially unhindered via an extension of the furniture fitting.

[0005] A third disadvantage of the state of the art is that, when particularly demanding requirements are placed on the furniture fittings, such as when connecting to heavy, movable furniture parts, the weight of the furniture fittings increases significantly due to the required rigidity of the furniture fittings. This results in inefficient use of resources and makes the furniture fittings difficult to manufacture. The option of using a variety of furniture fittings is an inadequate alternative that does not solve the problem and is also practically impractical for a large number of pieces of furniture.

[0006] Further furniture fittings are known from the documents ES 1 015 513 U and ES 1 012 634 U.

[0007] The objective technical object of the present invention is therefore to provide a furniture fitting which is improved compared to the prior art, as well as a piece of furniture and a method for producing such a furniture fitting, in which the disadvantages of the prior art are at least partially eliminated, and which are characterized in particular by increased stability and strength properties, a reduced weight and / or improved soundproofing properties of the furniture fitting.

[0008] This problem is solved by the features of claim 1.

[0009] It is therefore provided according to the invention that the two surfaces have at least one regular arrangement of successive elevations and depressions, wherein an elevation on one of the two surfaces is opposite a depression on the other of the two surfaces, and vice versa, wherein the at least one regular arrangement extends in a first direction and at least in a second direction transverse to the first direction, so that adjacent to a depression there is in each case a first elevation in the first direction and a second elevation in the second direction.

[0010] This makes it possible to ensure increased stability, in particular rigidity, load-bearing capacity, bending strength, and torsional strength, with identical material thickness by deviating from a smooth surface. When forces are transmitted to the at least one sheet metal piece, forces can be absorbed in a particularly favorable manner by the at least one sheet metal piece via the geometry that deviates from the smooth surface, in particular by means of an increased section modulus. This makes it possible to reduce the material thickness of the at least one sheet metal piece, given the specific requirements placed on the at least one sheet metal piece.

[0011] On the other hand, it makes it possible to increase the maximum requirements for the at least one sheet metal piece, since, for example, in the case of maximum material thicknesses due to manufacturing technology, the recesses and elevations allow more weight to be absorbed by the at least one sheet metal piece while maintaining the same weight. Furthermore, by reducing the weight of the at least one sheet metal piece, more sheet metal pieces can be transported and resources such as material, costs, and / or CO2 emissions can be saved during production.

[0012] Another positive feature is that, thanks to the surface structure created by the elevations and depressions, sound is absorbed to a high degree by the at least one sheet metal piece via the at least one regular arrangement and transmitted to a low degree, thereby reducing reflection and / or the generation of sound. Furthermore, the aesthetic appearance of the at least one sheet metal piece is enhanced.

[0013] Due to the surface structure - due to the at least one regular arrangement - a material and weight saving can be achieved universally in a wide variety of furniture fittings such as furniture hinges, furniture flaps, furniture fittings, furniture guides and / or component parts of furniture fittings through a reduced material thickness with the same strength and / or an increased strength with the same material thickness, whereby in particular acoustic and optical properties are improved.

[0014] The regular arrangement can be introduced—in particular partially or completely—for example, by embossing, rolling, and / or profiling into the at least one sheet metal piece before and / or after any bending and / or embossing step. In general, the regular arrangement can be introduced into the at least one sheet metal piece in a superimposed manner to form a corrugation and / or profiling.

[0015] By corrugating the at least one sheet metal piece over the at least one regular arrangement, an additional stiffening effect is achieved, wherein a neutral fiber can be extended in the forming of the at least one sheet metal piece, for example, existing sheet metal bending machines can be used and / or no incisions or one-sided countersinks in a surface of the at least one sheet metal piece are required for the at least one regular arrangement.

[0016] As stated at the outset, protection is also sought for a piece of furniture having at least one first furniture part and at least one second furniture part, wherein the piece of furniture comprises at least one furniture fitting with which the at least one first furniture part is mounted, preferably movably, on the at least one second furniture part.

[0017] This allows for a reduced number of furniture fittings required for moving and / or storing furniture components, enhancing the aesthetic appeal of the furniture. Furthermore, heavier furniture components can be used with furniture fittings of a given material thickness—especially the maximum material thickness—in the furniture.

[0018] As stated at the outset, protection is also sought for a method for producing at least one such furniture fitting, preferably at least one pull-out guide, a flap fitting or a hinge, characterized by the method steps, preferably following one another in the specified order: at least one flat sheet of metal is provided, in at least one partial area of ​​the at least one sheet of metal at least one regular arrangement of successive elevations and depressions is incorporated on two surfaces spaced apart from one another by a material thickness of the sheet of metal, wherein an elevation on one of the two surfaces is opposite a depression on the other of the two surfaces, and vice versa, wherein the at least one regular arrangement extends in a first direction and at least in a second direction transverse to the first direction, so that adjacent to a depression there is in each case a first elevation in the first direction and a second elevation in the second direction, the at least one sheet of metal is formed into at least one component of the furniture fitting to be produced by at least one bending, punching, cutting, coating and / or embossing step.

[0019] The method is particularly flexible in the production of at least one furniture fitting since, for example, after introducing a microstructure through the elevations and depressions, areas can be punched out of the sheet metal, which is also possible with the settings of a punching machine for commercially available furniture fittings, the sheet metal can then be bent to the desired geometric configuration and further punching work can be carried out by the punching machine, whereby embossings can be introduced into the existing microstructure of the sheet metal at any time.

[0020] Protection is also sought for a use of the formation of at least one regular arrangement of successive elevations and depressions on two surfaces, spaced from one another by a material thickness of a sheet, of at least one sheet metal piece made from a sheet metal, in particular a web, of a furniture fitting, wherein an elevation on one of the two surfaces is opposite a depression on the other of the two surfaces, and vice versa, wherein the at least one regular arrangement extends in a first direction and at least in a second direction transverse to the first direction, so that a first elevation in the first direction and a second elevation in the second direction are arranged adjacent to a depression in order to increase a rigidity and / or sound absorption of the furniture fitting at least in some regions.

[0021] The elevations and depressions make the furniture fitting particularly user-friendly, increasing the comfort of using the furniture fitting.

[0022] Due to the regular arrangement with adjacent raised sections, the at least one sheet metal piece exhibits a regular, flat arrangement, which allows for a particularly effective reduction in material thickness while maintaining the same stability and / or strength. Furthermore, the optical and acoustic properties of the furniture fitting are particularly positively influenced.

Fig. 10a in a top view.

[0068] The Figuren 1a bis 4b show non-inventive embodiments of furniture fittings 1 from the prior art without a regular arrangement 9 of elevations 10 and depressions 11. The regular arrangement 9 can be used in all existing sheet metal pieces 5 in order to improve the respective furniture fitting 1 with regard to stability, strength, weight, transport, acoustic and optical properties.

[0069] Fig. 1a shows a furniture fitting 1 in the form of a pull-out guide 33 with a plurality of embossings 16 and punched-out portions 29, which were introduced into a component 20. The furniture fitting 1 comprises four sheet metal pieces 5 in the form of a web, which are formed by a bending process of a sheet metal 4.

[0070] Fig. 1b differs from Fig. 1a in that the pull-out guide 33 is shown from a side view. The four sheet metal pieces 5 each have two surfaces 7, 8, which are spaced apart from each other by a material thickness 6.

[0071] Fig. 2a shows an arrangement with a drawer pull-out guide 33 and a drawer side wall 38 in a perspective view. Fastening sections 39, 40 of a first guide rail 41 each have one or more fastening points 42, 43 for fastening to a furniture body. A third guide rail 44 is connected or detachably connectable to the drawer side wall 38, with a second guide rail 45 being movable between the first guide rail 41 and the third guide rail 44.

[0072] A coupling element 46 is arranged on the first guide rail 41, which can be releasably coupled to a driver 47 of a retraction device 48 mounted on the third guide rail 44, so that the third guide rail 44 is gripped by the driver 47 towards the end of the closing movement and can be retracted into a closed end position by a force accumulator of the retraction device 48. This spring-supported retraction movement of the third guide rail 44 can be dampened to a closed end position by a damping device 49, preferably with a hydraulic piston-cylinder unit.

[0073] The drawer side wall 38 is designed as a hollow chamber profile with an inner profile wall 50 and an outer profile wall 51 spaced therefrom. The drawer side wall 38 forms a downwardly open channel 52 extending in the longitudinal direction of the drawer side wall 38, in which channel the third guide rail 44 can be arranged. The drawer side wall 38 further comprises a first fastening device 53 for connecting to a rear wall, a second fastening device 54 for connecting to a front panel, and a support 55 for supporting a drawer bottom.

[0074] Fig. 2b shows the first guide rail 41 with the fastening sections 39, 40 to be mounted on the furniture body. The first guide rail 41 has a U-shaped or C-shaped section in cross-section, in which a carriage 56 and a separate further carriage 57 are slidably mounted for guiding and supporting the second guide rail 45. The carriage 56 and the further carriage 57 are slidably mounted in a common running surface 26. The carriage 56 has load-transmitting rolling elements 27, the axes of rotation of which are spaced apart from one another in the vertical direction and are thus arranged in separate running surfaces 26.The carriage 56 also has lateral support rollers 57 with vertically extending axes of rotation in the assembled position, wherein the lateral support rollers 57 are movable on the one hand along a vertical web of the first guide rail 41 running in the longitudinal direction (L) and on the other hand along a vertically extending web of the second guide rail 45. By means of a toothing 58 arranged or formed on the carriage 56, a movement of the carriage 56 can be synchronized via a gear with a movement of another carriage 56, which is displaceably mounted between the second guide rail 45 and the third guide rail 44.

[0075] Fig. 3a shows a furniture fitting 1 in the form of a component 20 designed as a flap fitting 34. Cutouts 29 in the surfaces 7, 8 through the material thickness 5 are designed to accommodate fastening means 30 and are cylindrical, whereby a pivot pin can be mounted on the cutouts 29.

[0076] Fig. 3b differs from Fig. 3a only in that the furniture fitting 1 is shown from the side. The flap fitting 34 has three sheet metal pieces 5, to which a regular arrangement 9 can be applied.

[0077] Fig. 4a shows a furniture fitting 1 - designed as a hinge 35 - with cutouts 29, which releases an adjusting element 31 of an adjusting device 32, so that the adjusting element 31 can be actuated by means of a tool.

[0078] The furniture fitting 1 is designed to provide a movable mounting of a first furniture part on a second furniture part, wherein the furniture fitting 1 comprises sheet metal pieces 5 made from a sheet metal 4, which are designed in the form of webs.

[0079] Fig. 4b differs from Fig. 4a merely in that the furniture fitting 1 is shown in a front view. It is conceivable to introduce a regular arrangement 9 into the three sheet metal pieces 4 before or after a bending process of the sheet metal 4 of the furniture fitting 1, with the regular arrangement 9 particularly preferably being introduced before the bending process.

[0080] Fig. 5 shows a sheet metal 4 with two surfaces 7, 8 spaced apart from each other by a material thickness 6 of the sheet metal 4, wherein the two surfaces 7, 8 have a (schematically shown) regular arrangement 9 of successive elevations 10 and depressions 11, wherein an elevation 10 on one of the two surfaces 7, 8 is opposite a depression 11 on the other of the two surfaces 8, 7, and vice versa. The material thickness 6 of the sheet metal 4 is selected (not restrictively) to be 0.5 mm.

[0081] A neutral fiber 36 is schematically shown in dashed lines in the sense of a reference plane relative to the elevations 10 and depressions 11 (due to the introduction of the regular arrangement 9).

[0082] Fig. 6a shows a three-dimensional embodiment of the regular arrangement 9, wherein the regular arrangement 9 extends in a first direction 12 and in a second direction 13 transverse to the first direction 12, so that adjacent to a depression 11 there is arranged a first elevation 10 in the first direction 12 and a second elevation 10 in the second direction 13.

[0083] On each surface 7, 8, maxima 14 of the elevations 10 and depressions 11 of the regular arrangement 9 are arranged on imaginary lines parallel to one another. The elevations 10 and depressions 11 of a first line are offset by half a distance 19 between two elevations 10 or depressions 11 relative to the elevations 10 and depressions 11 of a second line directly adjacent to the first line, thereby particularly promoting an increase in flexural rigidity through a wave structure in two dimensions.

[0084] The elevations 10 and depressions 11 of the regular arrangement 9 are formed by the penetration of a pointed extension of a roller or a stamp, with the shape of the elevations 10 and depressions 11 being truncated pyramid-shaped with a radius of curvature depending on the material thickness 6. In general, the shape can also be pyramid-shaped, conical, or truncated cone-shaped.

[0085] On both surfaces 7, 8, three adjacent elevations 10 have maxima 14, each of which is arranged in a common plane 17, wherein a normal distance 18 of these planes 17 is increased by the regular arrangement 9 compared to the material thickness 6. In this embodiment, an increase in the material thickness by 0.2 mm was chosen due to the elevations 10 and depressions 11.

[0086] Two immediately consecutive elevations 10 and depressions 11 on one of the two surfaces 7, 8 have a distance 19 of 3.5 mm, which, however, can be adapted depending on the requirements of the furniture fitting 1.

[0087] Fig. 6b shows the surface structure of the regular arrangement 9, wherein a lower contour of the elevations 10 and depressions 11 are indicated by dashed lines, whereby it can be seen that the material thickness 6 of the sheet 4 is the same or constant over the entire area of ​​the regular arrangement 9 (neglecting varying plastic deformations between the maxima 14 and flanks of the elevations 10 and depressions 11).

[0088] Two immediately consecutive elevations 10 and depressions 11 have a distance 19 on one of the two surfaces 7, 8, the distance 19 being chosen to be five times as large as the normal distance 18.

[0089] The planes 17 between the maxima of the elevations 10 and the maxima 14 of the depressions 11 have a normal distance 18', which is 0.2 times as large as the material thickness 6 of the sheet 4.

[0090] Fig. 7 shows the sheet metal 4 for the production of the furniture fitting 1, wherein the regular arrangement 9 of successive elevations 10 and depressions 11 exhibits a periodicity. The periodicity is formed in the form of a two-dimensional alternation of elevations 10 and depressions 11 (analogous to a sinusoidal wave structure).

[0091] Punchings 29 and / or embossings 16 can be carried out before a bending process and / or after a bending process to form the component 20.

[0092] Fig. 8 shows a pull-out guide 33, wherein in the detailed section it can be seen that the sheet metal pieces 5 have embossings 16 which extend over a plurality of elevations 10 and depressions 11 of the regular arrangement 9.

[0093] In general, different sheet metal pieces 5 can have different regular arrangements 9 with specific geometries. Varying regular arrangements 9 within a sheet metal piece 5 are also conceivable, which can differ, for example, in the periodicity, the spacing 19, and / or a standard spacing 18, 18'. The regular arrangement 9 extends over 100% of the furniture fitting 1.

[0094] Fig. 9a shows that the sheet metal pieces 5 are arranged on a profiled component 20 of the furniture fitting 1, wherein the component 20 is partially U-shaped in cross-section. The regular arrangement 9 is visible on both surfaces 7, 8 in the form of elevations 10 and depressions 11.

[0095] Fig. 9b differs from Fig. 9a merely in that the pull-out guide 33 is shown in a top view. The section of a surface structure of the regular arrangement 9 shows that the sheet metal pieces 5 have punched portions 29 and are designed, among other things, as fastening means 30 for a furniture component.

[0096] Fig. 10a shows a sheet metal part 4 with a regular arrangement 9, wherein the regular arrangement 9 extends over extensive local areas. In general, the local area can also be arranged only at an edge 22 of a sheet metal part 5 and / or at a connection point 23 of a sheet metal part 5, at which the sheet metal part 5 is connected or connectable to another component 24 of the furniture fitting 1.

[0097] In this embodiment, the sheet metal 4, which comprises the sheet metal pieces 5 after a bending process, has two flat surfaces 25 which are free of regular arrangement 9.
