Description

[0001] The invention relates to a manufacturing method for a planar furniture component, a door leaf or the like, comprising a core made of wood or a wood substitute material.

[0002] Furniture front panels coated with veneered surfaces, especially real wood surfaces, adhesive films, thermal films, or other plastic coverings, are well-known and proven in a wide variety of designs. This coating can also be used to provide a wood substitute material such as fiberboard, chipboard, or blockboard with a high-quality surface, for example, with a wide variety of wood and plain decors that are almost indistinguishable from real wood components while maintaining high quality. This allows furniture fronts with a wide variety of decors to be produced cost-effectively and quickly in response to market changes.

[0003] In addition to such coatings, varnishes are available which, for example, can also fill pores, if necessary after sanding the surfaces to be varnished, and which can also impart a high optical quality, especially to the wood substitute materials mentioned.

[0004] Such flat furniture components can be used as furniture fronts or sides, as furniture doors or flaps, but also as door leaves, table tops or the like.

[0005] In order to give such extensive components a modern, largely distinctive design, the surfaces are often structured by incorporating piping, glass compartments or windows and / or a colour design, as is known, for example, from the documents DE 1 199 962 B or DE 39 26 161 C3.

[0006] Against this technical background, the invention sets itself the task of providing a designer with a manufacturing method for a planar furniture component, for a door leaf or the like, in which color and spatial-geometric structures are combined.

[0007] This technical problem is solved by a manufacturing method for a planar furniture component, for a door leaf or the like, having a core made of wood or a wood substitute material, in which, according to claim 1, in a first method step, spatial-geometric structures in the form of recesses set back from a surface of a flat side are introduced by a pressing process between two rollers, whereby an endless core is provided with the recesses in a constant pitch, or by pressing between plates, in a second method step, the furniture component is varnished and in a third method step, the surface is sanded or rolled while matting the varnish on the surface to introduce colored structures.

[0008] When high-gloss lacquers are used, a visual play of colors and a visual contrast are created, as the remaining shiny recesses appear to stand out against the matte surface. A surprising illusion that deceives the viewer's eye. This impression can be further enhanced by the way the recesses are arranged.

[0009] Pressing between plates, possibly also on multiple sides, is preferred because the high contact pressure of modern presses allows the recesses to be formed very precisely, so that an intermediate step in the form of grinding the upper side after the recesses have been made can be dispensed with, which will usually be necessary, especially after the recesses have been made by milling.

[0010] On the other hand, such grinding after the recesses have been made ensures that a recess has a sharp edge against the surface, which creates a clear contrast between the remaining matt surface and the shiny recess.

[0011] It is preferred that a surface contour of a recess be closed. In a view of the component according to the invention, such a recess often appears window-like, offering a view through the matte surface of the component.

[0012] It can also be provided that the surface contour of a recess is straight, particularly rectangular. Pressing between two rollers is also a suitable method for creating such recesses. With such a design, a designer will strive to incorporate a regularly repeating pattern of recesses into a surface.

[0013] However, a preferred embodiment is one in which a continuous surface contour of a recess encloses a simply connected area. Such contours of a plurality of recesses can define a seemingly random pattern, which lends a component according to the invention a high degree of individuality. In particular, flat-shaped, elongated recesses terminating in rounded tips and arranged in close proximity to one another are considered. These recesses are then separated by comparatively narrow webs of the remaining, matte surface, creating a net-like pattern.

[0014] In addition to smooth, groove-like recesses, it is particularly important that a recess has a spatial structure beneath the surface. A recess with grooves is further preferred, preferably arranged in an irregular manner along the length of the recess. Such a recess then appears to be roughly brushed, which then allows for a varied structuring of the furniture component as a whole.

[0015] Special design possibilities for a designer are offered by the possibility of one or, in particular, several recesses extending over an edge of the furniture component or door leaf. This possibility for structuring a furniture component according to the invention opens up new avenues, particularly for thick door leaves, tabletops, or the like.

[0016] Components according to the invention and their manufacture are further explained with reference to the drawing, which only schematically illustrates exemplary embodiments. The drawing shows: Fig. 1: a partial plan view of a top side of a first furniture component according to the invention, Fig. 2: a section of a second embodiment, Fig. 3: a section along the line III, III in Fig. 2, Fig. 4: a section of a third embodiment in a plan view and Fig. 5: an isometric view of a fourth embodiment.

[0017] Fig. 1 shows a plan view of a planar furniture component 1 according to the invention with a core made of wood or wood substitute material such as a fiberboard, a chipboard or the like.

[0018] In a first process step, recesses 2, 3 are introduced into the furniture component 1, which in the embodiment of the furniture component 1 according to Fig. 1 groove-like and have a closed surface contour 4 which, when held straight, spans a rectangle.

[0019] After introducing the recesses 2, 3, in the embodiment of the furniture component 1 according to Fig. 1 is also relatively easy to achieve by milling, but preferably by pressing, the surface 5 is optionally ground, by which a comparatively sharp edge is obtained between the surface 5 and the edges of the recesses 2, 3.

[0020] Subsequently, the surface 5 and the recesses 2, 3 are painted, preferably with a high-gloss paint, in a conventional manner, which may also include priming, sanding, or the like. Following the painting, the surface 5 is treated by sanding or rolling, so that the paint on the surface 5 has a matte finish, while the paint on the recesses 2, 3 remains high-gloss. This results in a highly structured furniture component.

[0021] In the embodiment of a furniture component 6 according to Fig. 2, window-like recesses 7 have been introduced into the surface 8, preferably by pressing. The contour 9 of these recesses 7 is also straight and closed, spanning a rectangle. As the section according to Fig. As shown in Figure 3, the recesses 7 below the surface 8 of the furniture component 6 are structured, having grooves 10 in the longitudinal direction of the recesses 7. Such a structure resembles a brushed wooden surface.

[0022] Also for the furniture component 11 according to Fig. 4, recesses 12 are made in the upper side 13 of the furniture component 11 in a window-like manner. The contour 14 of the recesses 12 is also closed all the way around, but continuous and enclosing a simply connected area, without corners, points or the like.

[0023] Below the surface 13, the recesses 12 are in turn provided with a spatial structure in the form of grooves 15 in the longitudinal direction of the recesses 12.

[0024] A preferred embodiment of a furniture component 16 shows Fig. 5. Such a strong material furniture component 16 can be used excellently as a table top, door leaf or the like.

[0025] In addition to a section 17 without recesses, which appears matte due to the manufacturing process, the furniture component 16 has a plurality of recesses 19 arranged directly next to one another towards an end face 18, which partially extend over the edge 20 from the surface 21 to the end face 18. The recesses 19 are flat-shaped, elongated and delimited by a mostly closed contour 22, so that relatively narrow webs 23 remaining between the recesses 19 form a net-like pattern of the remaining matte surface 21.

[0026] The recesses 19, which end in rounded tips 24, 25, provide a seemingly random pattern which gives the furniture component 16 according to the invention a high degree of individuality.

[0027] This is further enhanced by the measure that these recesses 19, even beyond the edge 20, are provided with a structure in the form of grooves 26.
