Description

[0001] Fitting for a piece of furniture

[0002] The invention relates to a fitting, preferably a hinge, for a piece of furniture, comprising a first fitting part for mounting on a furniture carcass, a second fitting part for mounting on a movable furniture part, at least one pivot lever for articulated connection of the first fitting part with the second fitting part, and at least one operating element, wherein the at least one operating element is provided for adjusting a relative position of the first fitting part with respect to the second fitting part and / or the furniture carcass and / or the movable furniture part. Furthermore, the invention relates to a piece of furniture with at least one such fitting and to a method for manufacturing such a fitting.

[0003] Such a fitting is already known from EP 4 321 716 A2. These fittings are constantly being further developed with regard to their strength properties during long service life, as well as their functionalities in terms of user-friendly operation by an installer or end user. This development ensures increasingly delicate or compact fittings and more efficient assembly and adjustment processes, since for fittings in the visible area of ​​furniture as furnishings, an aesthetic appearance is of significant importance, and user-friendly operation is essential for a multitude of integrated functions.

[0004] A disadvantage of the current state of the art, however, is that this combination of competing aspects necessitates trained specialists for the correct adjustment of the fitting to ensure proper setting / adjustment. Furthermore, the attempt to reduce the amount of material used in component parts inevitably leads to diminished properties of the fitting – for example, reduced stability due to less material being used in load-bearing components. If the fitting is damaged and no longer in the form intended by the manufacturer for proper use or by the end user for aesthetic purposes, it must be replaced with a new fitting.

[0005] The objective technical object of the present invention is therefore to provide a fitting that is improved compared to the prior art, as well as to specify an improved method for manufacturing such a fitting, in which the disadvantages of the prior art are at least partially eliminated, and which are characterized in particular by high user comfort, reduced operating errors and / or favorable properties with regard to service life and / or visual appearance.

[0006] This problem is solved by the features of claim 1.

[0007] According to the invention, it is therefore provided that the first fitting part and / or the second fitting part is at least partially provided with a coating, wherein at least one area of ​​the fitting visible in the state of use is uncoated or coated with a coating that differs from the coating.

[0008] This makes it possible to extend the service life of the fitting due to increased corrosion protection and chemical resistance. Furthermore, the appearance and material characteristics of the underlying base material – generally metal – are not affected, as the coating effectively maintains the fitting's properties, such as increased scratch resistance and repellency. Additionally, the coating allows for a fitting where fingerprints are less visible or even invisible, thus enhancing the furniture's appearance and reducing cleaning requirements.

[0009] Furthermore, the coating can influence friction properties – for example, between the joint lever and any existing damping mechanism of a hinge cup. Additionally, a wide range of visual appearances – such as matte or smooth surfaces – can be flexibly generated, for example, through the coating composition.

[0010] In addition, the coating has the positive property of serving a dual purpose: it allows specific component parts—especially at least one operating element—to stand out visually, making them more easily recognizable to the operator or installer during adjustment or operation, thus increasing ease of use. For example, areas of the first or second fitting part can be selectively left uncoated to draw attention to the uncoated elements or to effectively indicate the position of a specific operating element to the user. Unlike other surface treatments, such as chemical post-treatment, this coating is particularly well-suited for this purpose.

[0011] A component can be provided as an uncoated or with a different coating visible area, which is particularly preferably in the at least one operating element; however, it can alternatively or additionally be in the form of a cover cap.

[0012] The coating, which differs from the coating, may differ, for example, in its color, while alternatively or additionally other aspects of the coating – such as the composition of the coating or the appearance of the coating – may vary.

[0013] For example, this can prevent an end user from making an adjustment to the fitting that should be reserved for the installer, or it can suggest to the end user that this control element is intended for user adjustment. In general, standard component parts can be visually distinguished from control elements.

[0014] In general, the hinge lever(s) are also coated. It is generally irrelevant whether the coating is applied when the fitting is disassembled or at least partially assembled. Preferably, uncoated parts are added after the coated components of the fitting have been assembled or after the assembled components have been coated. It is also conceivable to fully assemble the fitting and then selectively coat specific areas of the fitting.

[0015] Of particular relevance in the context of the invention is the visible area of ​​the fitting in its state of use on the furniture, whereby the properties – such as coloring – in the context of the invention generally (but not necessarily) relate at least to the visible area of ​​the component parts of the fitting, whereby in general, for example, the surface used for mounting (e.g., the underside of a mounting plate or the underside of a hinge cup) of the fitting or the fitting completely (possibly apart from component parts supplementing the fitting, such as in connection with a damper or a housing) may also be coated in order to, for example, inhibit corrosion of this area of ​​the fitting.

[0016] The uncoated area of ​​the fitting is particularly preferably in the form of at least one operating element, wherein the uncoated or differently coated area can generally be in the form of an actuating device or a control device for a damper and / or a switching element for activating or deactivating the damper and / or in a release device for decoupling a band arm from a mounting plate (e.g. by means of a clip connection).

[0017] For example, the color red can be used as a signal color to visualize a component – ​​such as the control element, the release mechanism or the damper activation – with increased relevance.

[0018] Particularly preferred is the coating covering essentially the entire visible area of ​​the fitting in its operating state, except for at least one operating element.

[0019] As stated at the beginning, protection is also sought for a piece of furniture with at least one such fitting. The furniture can be, for example, a cabinet, a chest, and / or a piece of furniture with flaps, although other types of furniture are also possible.

[0020] As stated at the outset, protection is also sought for a method for manufacturing such a fitting, wherein - a first fitting part and / or a second fitting part of the fitting is at least partially provided with a coating and

[0021] - the fitting is mounted, whereby at least one area of ​​the fitting visible in the state of use remains uncoated or is provided with a coating different from the coating, or

[0022] - the fitting, comprising the first fitting part and the second fitting part, is mounted and

[0023] - the first fitting part and / or the second fitting part is provided with a coating at least in certain areas, whereby at least one area of ​​the fitting visible in the state of use remains uncoated or is provided with a coating different from the coating.

[0024] In general, the process steps do not need to be carried out chronologically, provided that an uncoated area remains in the visible area of ​​the fitting in its used state, or that an area has a coating different from the coating. The timing of the coating is irrelevant and can occur before or after the installation of the first fitting component with the second fitting component, and, if applicable, before or after the installation of an uncoated component or a component with a coating different from the coating.

[0025] Preferably, the first fitting part and the second fitting part are mounted following the coating process step, wherein a component part, particularly preferably the at least one operating element, is then mounted without coating or with a coating different from the coating to form the fitting. Advantageous embodiments of the invention are defined in the dependent claims.

[0026] According to an advantageous embodiment of the invention, the coating has a first color and the at least one control element has a second color, wherein the first color and the second color differ from each other.

[0027] For example, the color of the operating element may be determined by the uncoated area of ​​the fitting, and the color of the coating may be determined by a different color scheme. In general, the first fitting component and the second fitting component, or at least one operating element and fasteners, or a multitude of operating elements, may have varying colors—preferably due to the coating. For example, the fitting may be predominantly gold-colored, with at least one operating element standing out visually from the standard components of the fitting due to its silver color.

[0028] Advantageously, the coating thickness is provided to be in a range between 30 pm and 60 pm.

[0029] The coating thickness can be achieved in a single coating process step or through multiple coating process steps, resulting in several layers of the coating. A coating thickness of 30 pm to 60 pm provides sufficient corrosion / chemical protection and / or scratch resistance for fittings while minimizing resource consumption.

[0030] It has proven advantageous to have at least one operating element left uncoated. This at least one operating element can be made of stainless steel or a high-quality metal, or protected against environmental influences in some other way (for example, by a different coating). The uncoated design of at least one operating element creates a contrast with the coated areas of the fitting.

[0031] According to an advantageous embodiment of the invention, it is provided that the first fitting part and / or the second fitting part is essentially made of metal, preferably steel.

[0032] In general, fittings made of plastic and / or transparent materials can also be used.

[0033] It has proven advantageous that the first fitting part and / or the second fitting part is predominantly covered with the coating, at least in the area visible during use.

[0034] Particularly preferably, the coating extends over the entire visible area of ​​the first fitting part and the second fitting, and optionally also over the invisible area away from the at least one operating element for the fitting, whereby, for example, fastening devices or actuating or control elements for a damper that may be present can also be excluded from a coating.

[0035] An advantageous embodiment of the present invention consists in the fact that the at least one operating element is concealed by at least one cover cap detachably fixed to the fitting. Particularly preferably, the at least one cover cap is provided with a coating or a different coating. Generally, a first cover cap can be provided for the at least one operating element and a second cover cap for the at least one fastening device or a further operating element, whereby a single cover cap can also be provided for all operating elements and / or for the at least one operating element and the at least one fastening device. The at least one cover cap can, for example, be arranged on a hinge arm or on a hinge cup.

[0036] Particularly preferred is that the fitting is designed as a hinge arm hinge with a mounting plate for mounting on the furniture body, a hinge arm mounted on the mounting plate in articulated connection to the at least one articulated lever and / or a hinge cup in articulated connection to the at least one articulated lever, wherein preferably at least one, particularly preferably at least two, operating elements are arranged on the hinge arm of the fitting.

[0037] The hinge arm preferably comprises a pivot lever which is pivotable relative to a mounting plate and / or a hinge cup or a fastening device (other than a hinge cup) that can be mounted on the movable furniture. The pivot axis of the pivot lever with respect to the first fitting part and / or the second fitting part can be oriented parallel or orthogonal to a longitudinal direction of the fitting or a horizontal plane of the fitting (generally parallel to the plane of the mounting plate of the fitting) in the fitting's operating state.

[0038] In one embodiment of the invention, it is provided that the at least one operating element is arranged on the first fitting part and / or on the second fitting part and / or is in the form of a side adjustment device or a height adjustment device or a depth adjustment device.

[0039] The at least one operating element is preferably provided for adjusting the position of the hinge arm and / or the hinge cup relative to the mounting plate, whereby other component parts of the fitting may also be adjustable and / or the fitting is not limited to a hinge arm hinge. For example, in the case of a piece of furniture in the form of a cabinet with a flap as a movable furniture part oriented about a vertically oriented pivot axis, it may be provided that the depth, height, and lateral position of a fitting part or the movable furniture part relative to the furniture carcass or a mounting plate of the fitting are adjustable.

[0040] According to a preferred embodiment of the invention, the fitting comprises at least one fastening device for mounting the first fitting part to the furniture body or the second fitting part to the movable furniture part, wherein it is preferably provided that the at least one fastening device

[0041] - is designed to be free of coatings,

[0042] - has a coating that differs from the coating ,

[0043] - is covered with a protective cap ,

[0044] - has a color that differs from the color of the coating and / or

[0045] - is intended for mounting the band arm, if present, to the mounting plate, if present.

[0046] The at least one fastening device can, for example, be in the form of a screw and preferably serves to mount the hinge arm to the mounting plate or to mount the hinge cup. Other fittings may also be provided and / or other components of the fitting may be connected to the furniture or the fitting via the at least one fastening device. In general, a fastening device can have a dual function as an operating element for adjusting the fitting, preferably in the relative positioning of the second fitting part with respect to the first fitting part.

[0047] It has proven advantageous that the coating is a, preferably colored, lacquer and / or is applied to the fitting by means of electroplating and / or compressed air atomization.

[0048] Furthermore, it is preferably provided that the coating is in the form of a two-component polyurethane-based coating comprising an acrylic adhesion promoter, wherein the coating preferably comprises a metal substrate and / or a plastic substrate.

[0049] This has proven to be particularly advantageous for the material-characteristic properties of the coating as well as the adhesion properties to the fitting.

[0050] It is particularly preferred that

[0051] - the first fitting part and / or the second fitting part is pretreated at least partially by means of carbon dioxide radiation,

[0052] - a first layer of a coating with a layer thickness between 15 pm and 30 pm is applied at least partially to the first fitting part and / or the second fitting part by compressed air atomization and / or

[0053] - after at least partial evaporation of a solvent from the first layer, at least in certain areas on the first

[0054] A second layer of coating with a layer thickness between 15 pm and 30 pm is applied to the fitting part and / or the second fitting part by compressed air atomization.

[0055] Pretreatment can improve the adhesion of the coating to the fitting. Applying two layers can result in a particularly durable coating.

[0056] In a further embodiment of the present invention, it may be provided that an alkaline degreasing, passivation or fluorination is carried out immediately before or after the pretreatment process step and / or that forced drying is carried out in a process step immediately following the application of the second layer or any further applied layer in a temperature range between 65° and 95° for a period of 45 min to 90 min.

[0057] This ensures a particularly robust coating and / or a coating of particularly high quality on the fitting.

[0058] According to an advantageous embodiment of the invention, it is provided that at least one cover cap for at least one operating element and / or at least one fastening device of the fitting is pretreated and / or coated over two layers, wherein the at least one cover cap is attached to the first

[0059] The fitting part or the second fitting part is arranged.

[0060] The coating can correspond to the coating of the first or second fitting component, or it can be a different coating. The at least one cover cap ensures a uniform visual appearance of the fitting – for example, in a single color scheme – whereby, in the fitting's operating state, at least one operating element located below the cover cap can be visually revealed, for example, by removing the at least one cover cap, with an appearance that differs from that of the surrounding area of ​​the at least one operating element.

[0061] It is particularly preferred that at least one operating element and / or at least one fastening device is arranged on the fitting without a coating or with a coating that differs from the coating and / or in a color that differs from a color of the coating.

[0062] Further details and advantages of the present invention are explained in more detail below with reference to the description of the figures and the exemplary embodiments shown in the drawings. These show:

[0063] Figs. 1-3 show three varying constructive embodiments of preferred designs of a fitting in the form of a hinge arm with partial coating, wherein operating elements of the fitting are either uncoated or provided with a different coating, in a perspective view and

[0064] Figs. 4a-4h Flowcharts as illustrative representations of preferred embodiments of a method for manufacturing a fitting according to Figs. 1 to 3.

[0065] Fig. 1 shows a fitting in the form of a hinge 1 for a piece of furniture, wherein the fitting comprises a first fitting part 2 for mounting on a furniture carcass, a second fitting part 3 for mounting on a movable part of the furniture, a hinge lever 4 for articulated connection of the first fitting part 2 with the second fitting part 3, and three operating elements 5, wherein the three operating elements 5 are provided for adjusting a relative position between the second fitting part 3 and the first fitting part 2 or the furniture carcass. The number of operating elements 5 is generally arbitrary.

[0066] The first fitting part 2, the second fitting part 3, and the hinge lever 4 of this embodiment are at least partially coated with a coating 6, wherein a visible area of ​​the fitting in the operating state, in the form of one of the three operating elements 5, is coated with a coating 6a that differs from the coating 6, and the two other operating elements 5 are uncoated. The number of operating elements 5 that are uncoated or coated with a different coating 6a is generally arbitrary, and the area of ​​the fitting without coating 6 or with a different coating 6a is not limited to operating elements 5.

[0067] The alternative coating 6a differs from the coating 6 in that the coating 6 has two layers and the alternative coating 6a has only one layer, whereby the number of layers of the coating 6 and the alternative coating 6a is basically arbitrary.

[0068] The coating 6 has a first color and the three operating elements 5 have a second color, the first and second colors being different from each other. Generally, three or more varying colors can be present, for example, to assign one color to the installer of the fitting and another color to the end user of the fitting.

[0069] All three operating elements 5 of this embodiment are arranged on the first fitting part 2, whereby in general it may alternatively or additionally be provided that at least one operating element 5 is arranged on the hinge lever 4 or on the second fitting part 3.

[0070] Each of the following is a control element 5: a lateral adjustment device 11 for adjusting the lateral position of the second fitting part 3 relative to a mounting plate 8 of the first fitting part 2, a height adjustment device 12 for adjusting a vertical position of the movable furniture part relative to the mounting plate 8 of the first fitting part 2, and a depth adjustment device 13 for adjusting a lateral positioning (of the remaining third degree of freedom of the adjustment possibility of the fitting) of the movable furniture part relative to the mounting plate 8 of the first fitting part 2.

[0071] The coating thickness 6 is in the range between 30 µm and 60 µm. Coating 6 is in the form of a colored lacquer, which is applied to the fitting, for example, by electroplating or compressed air atomization.

[0072] The coating 6 is in the form of a two-component polyurethane-based coating comprising an acrylic adhesion promoter, wherein the coating 6 comprises a metal substrate and a plastic substrate.

[0073] The first fitting part 2, the hinge lever 4 and the second fitting part are essentially made of steel.

[0074] In the lower part of the view, two cover caps 7 are shown. The left cover cap 7 conceals the three operating elements 5 by releasably fixing the cover cap 7 to a hinge arm 9 of the first fitting part 2. The right cover cap 7 conceals the fastening devices 14 on a hinge cup 10 of the fitting after the fastening devices 14 – in the form of screws, nails, or other fasteners – have been installed. The cover caps 7 are generally not limited to hinge arm hinges 1 or the specific arrangement shown on operating elements 5 or for use with fastening devices 14.

[0075] The hinge arm fitting 1 includes a damper 19, which in this embodiment is arranged on the outside of the hinge cup 10. The damper 19 is covered by a damper housing 20 to protect it against contamination and to ensure its secure positioning in a hinge cup bore of the movable furniture part. The damper 19 is activated by force transmission via the joint lever 4 and an actuating device 22 by an actuating element 21 (which is translationally movable), whereby the damper 19 can generally dampen a closing and / or an opening movement of the fitting.

[0076] Fig. 2 shows a fitting according to a further preferred embodiment of a hinge arm hinge 1 in connection with two furniture panels of a piece of furniture, wherein a furniture panel can represent a flap or a cabinet wall.

[0077] The bandarm hinge 1 comprises a mounting plate 8 for mounting on the furniture carcass, a bandarm 9 mounted on the mounting plate in a pivot connection to the pivot lever 4, and a hinge cup 10 in a pivot connection to the pivot lever 4. Alternatively to the hinge cup 10, another fastening means for coupling the movement to the movable furniture part can be provided, for example, if this part is made of glass or does not have a hinge cup bore.

[0078] The band arm 9 has a large number of controls 5 in common.

[0079] - in an arrangement along a line in the longitudinal direction of the

[0080] fitting - arranged, wherein in general at least one of the operating elements 5 can be arranged on the mounting plate 8, on the hinge lever 4 or the hinge cup 10 .

[0081] The damper 19 is actuated by a (pivoting) actuating element 21 via a motion coupling with the articulated lever 4, the damper 19 being a linear damper. In general, alternative or supplementary damping mechanisms other than a linear damper may be provided.

[0082] The fitting comprises a variety of fastening devices 14 in the form of screws for mounting the first fitting part 2 to the furniture body and fastening means not shown for attaching the second fitting part 3 to the movable furniture part.

[0083] Fig. 3 shows a fitting according to a further preferred design embodiment, wherein in this embodiment, compared to Fig. 1, no height adjustment device 12 is shown as an operating element 5. This can, however, be added to the fitting.

[0084] The fitting can be fixed to the furniture by means of a fastening device 14, whereby the fastening device 14 is not limited to this connection. For example, the hinge arm 9 can be connected to the mounting plate 8 or the joint lever 4 to the first fitting part 2 or to the second fitting part 3 using a fastening device 14. The fastening device 14 can simultaneously act as an operating element 5.

[0085] The fastening devices 14 (not shown) for mounting on the furniture can be designed without a coating. The fastening device 14, as an operating element 5, has a coating 6a in a different color than the coating 6 and can be covered with a cap 7 when the fitting is in use on the furniture.

[0086] The coating 6 is formed by a hatch on the first fitting part.

[0087] 2 visualized, where the operating elements 5 do not have the coating 6. The first fitting part 2 and the second fitting part

[0088] 3 are predominantly covered with the coating 6 in the visible area during use, so that the sharpness is only for illustration purposes and the coating 6 also extends to adjacent surfaces - preferably also to non-visible surfaces.

[0089] Figures 4a to 4h show different options for carrying out a method for manufacturing a fitting according to the invention, wherein the fitting – ready for mounting on the furniture – has a selective coating 9. The flowcharts illustrate the interaction between coating process step(s) 17 and assembly process step(s) 18. The sequence of process steps can be extended or duplicated, wherein, for example, a coating process step 17 can be characterized by applying a plurality of layers of a coating 6 or a different coating 6a – the same applies to an assembly process step 18. For example, two coating process steps 17 can be provided consecutively.

[0090] In the method according to Fig. 4a, the fitting comprising the first fitting part 2 and the second fitting part 3 is mounted and subsequently the first fitting part 2 or the second fitting part 3 is provided at least partially with a coating 6, so that an area of ​​the fitting visible in the state of use remains uncoated or is provided with a coating 6a that differs from the coating 6.

[0091] In the method according to Fig. 4b, the first fitting part 2 or the second fitting part 3 of the fitting is provided with a coating 6 at least partially (preferably completely - optionally away from operating elements 5 or fastening devices 14) and the fitting is mounted, wherein an area visible in the operating state of the fitting (preferably at least one operating element 5) of the fitting remains uncoated or is provided with a coating 6a that differs from the coating 6.

[0092] Fig. 4c shows a multi-stage process, in which the fitting is first partially assembled, for example, by connecting the first fitting part 2 to the second fitting part 3 (and, in the case of a hinge arm hinge 1, optionally the hinge arm 9 to the mounting plate 8) via the hinge lever 4. Subsequently, the partially assembled fitting is provided with a coating 6, and the fitting is structurally completed by assembling the remaining component parts – for example, operating elements 5 or (preferably pre-assembled) fastening devices 14. Finally, a visible area of ​​the fitting – for example, the cover cap 7 or at least one operating element 5 – is provided with a different coating 6a.

[0093] The process according to Fig. 4e differs from the process according to Fig. 4c only in that the application of a different coating 6a is omitted, leaving an uncoated or coating-free area on the fitting.

[0094] Fig. 4d shows a multi-stage process in which the first fitting part 2 and the second fitting part 3, and preferably the hinge lever 4, are provided with a coating 6 in disassembled form, and the fitting is then partially assembled. Before final assembly of the fitting, an area or component of the fitting is provided with a different coating 6a.

[0095] Fig. 4f differs from the process according to Fig. 4d only in that between the coating process steps 17 the fitting is mounted in an assembly process step 18 - for example the operating element 5 is selectively coated on the fitting.

[0096] Figures 4g and 4h illustrate two further methods, wherein in Figure 4g, for example, the first fitting part 2 or the second fitting part 3 is provided with a coating and at least one operating element 5 with a different coating 6a, and the fitting is then brought into a delivery state. In Figure 4h, for example, a coating 6 is applied to the first fitting part 2 or the second fitting part 3, wherein the assembly process is divided into an assembly of the coated component parts of the fitting and an assembly of uncoated component parts of the fitting.

[0097] In connection with the varying processes according to Figs. 4a to 4h, it may be provided that the first fitting part 2 or the second fitting part 3 is pretreated by means of carbon dioxide blasting, whereby the application of a first layer 15 (preferably by compressed air atomization) and a second layer 16 (preferably by compressed air atomization) of the coating 6 or the alternative coating 6a may be provided. Before or after the pretreatment process step, alkaline degreasing, passivation or fluorination may be carried out, with forced drying being carried out in a subsequent process step.

[0098] The procedures are generally also applicable to other component parts of the fitting besides the first fitting part.

[0099] 2 and the second fitting part 3. Preferably, a cover cap 7 for an operating element 5 or a fastening device 14 is pretreated or coated over two layers 15, 16, wherein the cover cap 7 is attached to the first fitting part 2 - for example, the hinge arm 9 as a component of the first fitting part 2 when a fitting is a hinge arm hinge 1 - or to the second fitting part.

[0100] 3 is arranged. The cover cap 7 can alternatively be designed without coating.

[0101] An operating element 5 or a fastening device 14 can be arranged on the fitting without coating or with a coating 6a that differs from the coating 6 or in a color different from a color of the coating 6 or with the coating 6.
