Description:

The invention relates to an edge strip for the furniture or construction industry, in particular for the narrow surface coating of furniture panels, countertops or similar material plates, with a strip body of at least one base material, for. B. of thermoplastic material. Such edge strips or cover strips are also referred to simply as edges or edge bands or else as edge strips. They are preferably used to coat the narrow surfaces or end faces of material plates or plate-shaped workpieces such. As furniture panels or countertops (eg kitchen countertops). Such material plates are z. B. as wood panels or wood-based panels (eg., Particleboard, fiberboard or the like) or as composite panels. The attachment of the edge strips on the respective material plate is z. B. in a conventional manner by means of hot melt adhesives. However, the edge strips can also already be provided with a melt layer or functional layer in the course of production, which is then melted during processing with suitable sources (eg laser radiation, hot air, plasma or the like).

An edge strip of the type described above, in which the strip body or strip core is transparent, z. B. from EP 0 857 442 A2. On the back of the transparent strip core is a decorative coating or color coating. These moldings are also referred to in practice as the "3D edge." The edge is fastened to the furniture panel with its underside or back, on which the decorative coating or color coating is arranged, so that the decor remains visible through the transparent strip body , even after a subsequent machining surface treatment of the plastic strip

(see EP 0 857 442 A2). Such 3D edges have proven to be excellent in practice.

The invention has for its object to provide an edge strip for the furniture or construction industry of the type described above, which is characterized by a high-quality design with a simple structure.

To solve this problem, the invention teaches an edge strip for the furniture or construction industry, especially for the narrow surface coating of furniture panels, countertops or similar material plates, with a strip body of at least one base material, eg. B. of thermoplastic material, wherein in the strip body a plurality of (strip-shaped) slats are integrated, which are distributed over the width of the strip and extend in the longitudinal direction of the bar, wherein the slats extend over at least a portion of the thickness of the strip body and obliquely under a predetermined angle to the strip base are arranged. Preferably, the lamellae are at least partially formed by a lamella material, which has different optical properties than the base material.

The invention is based on the recognition that an edge strip with a high-quality design can be created if strip-shaped lamellas are integrated in the strip or in the strip body, so that the visual impression of the strip depends in particular on the viewing angle. This can be z. B. realize that the lamellae have a different color than the strip body itself or as the base material of the strip body.

Thus, in a preferred embodiment of the invention, it is provided that the strip body consists of a transparent base material and that the lamella material is not transparent. If then z. B. back a decor is arranged on the strip body, which is visible through the transparent strip body - as is common in 3D-edges, is caused by the blades according to the invention that depending on the selected setting angle and depending on the viewing angle, an overlap of the slats or . A review of the bottom decor page results. This results in different optical effects depending on the viewing angle. This lamellar effect makes it possible to vary or expand the decorative properties of basically known 3D edges with a transparent strip body and a backside decorative coating. In an alternative embodiment, however, the base material may not be transparent and only the fin material may be transparent, so that the back decoration is then only visible through the slats. Even with this, interesting optical effects can be achieved. Although the described louver effect can be implemented particularly preferably with edge strips having a decorative coating on the back (eg decorative foil and / or decorative print), it is alternatively within the scope of the invention to dispense with a backside decoration. In this case, the surface or end face of the corresponding material plate is then visible through the strip body and / or the lamellae. Such a configuration may be of particular interest if lamps are integrated in the material plate, because then a backlit edge band is created in the installed state, the passage light is dimmed by the slats and thus a glare is avoided or a

certain area can be illuminated. Alternatively, however, there is also the possibility in such backlit edge bands that, in spite of the backlighting, a rear-side decorative coating is provided, so that the backlight illuminates the decorative coating on the back.

As already explained, it is important that the lamellae at least partially have different optical properties than the strip body itself. B. be realized that both the inguinal body and the slats of basically the same material, eg. B. are made of the same thermoplastic material, but that the thermoplastic material in the region of the fins has a different color than the thermoplastic material of the base material. Alternatively, it is within the scope of the invention that the slats are at least partially made of a different material than the base material, for. B. of a thermoplastic other than the base material. There is also the possibility to integrate in the strip body made of thermoplastic plastic fins made of a material other than plastic, for. B. metallic lamella strips. Incidentally, it is within the scope of the invention to provide the fin material with additives that z. B. provide for afterglow (luminescence effect). In addition, the lamellae can also be made of fluorescent materials so that they are "black light active".

Preferably, the production of the edge strip according to the invention is carried out by plastic extrusion, wherein at least the strip body is made of a thermoplastic material as a base material. Particularly preferably, the lamellae are made of thermoplastic material as a lamella material. In this case, it is particularly advantageous, the edge strip by coextrusion of a thermoplastic material as

Base material and made of a second thermoplastic material as a fin material. As already described, these may be thermoplastics made of different polymers or copolymers. However, it is also within the scope of the invention that the two thermoplastic materials are made of the same polymers or copolymers and then z. B. only differently colored or additivized, so that z. B. one transparent plastic and the other plastic is colored. As already explained, the strip body can optionally be provided on the last back with a decor, z. B. with a decorative sheet or a decorative print, wherein on the front strip no decor is arranged so that the decor remains visible on the back of the strip through the strip body. The invention is based here on the known 3D edges.

The attachment of the edge strip according to the invention on the material plate can be done in the usual way. Thus, the bar or the strip body or the decorative layer can be provided on the back with a bonding agent for bonding with conventional hot melt adhesive. Alternatively, the edge strip can already be equipped in the course of production with an additional layer for attachment to a material plate, for. B. with a melt layer or functional layer, which can be activated or melted in the course of processing by means of energy. The arrangement and configuration of the slats can be adapted to the respective needs in terms of the design. Thus, it may be appropriate that the slats distributed over the width are arranged parallel to each other. Optionally or additionally, it may be advantageous that the slats distributed over the width are arranged equidistantly. at

Edge strips usual width, it is useful if distributed over the width of at least 5 fins, z. B. 5 to 30 fins, preferably 10 to 20 fins are provided. The strip body of the edge strip preferably has a thickness of 0.5 mm to 5 mm, z. B. 1 mm to 3 mm, preferably 1, 5 mm to 2 mm. The width of the last body can - before further processing or reworking on the furniture plate - z. B. 10 mm to 60 mm, preferably 20 mm to 50 mm. The thickness of the slats is preferably 0.05 mm to 0.1 mm, preferably 0.1 mm to 0.5 mm. It is also expedient if the lamellae at an angle to the strip base of 10 ° to 80 °, z. B. 30 ° to 60 °, more preferably 40 ° to 50 ° are arranged. It is optically particularly interesting if the slats are positioned and aligned so that, depending on the viewing angle, an overlap of the slats or a review of the lower decor side or on the underlying plate. For this purpose, the slats can be aligned and arranged so that the slats join in the plan view without significant overlap each other. For this purpose, reference is made to the description of the figures. The invention is also a plate, z. B. a furniture plate or countertop with an attached edge strip. The edge strip is therefore also placed in combination with the plate under protection.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. Show it:

1 shows an edge strip according to the invention with lamellae and rear decorative coating in a cross section,

Fig. 2 shows the object of Fig. 1 in the assembled state in a perspective view and

Fig. 3 shows a modified embodiment of the article according to

Fig. 2 in another view.

In Fig. 1, an edge strip 1 is shown for the narrow surface coating of furniture or countertops 2, wherein the edge strip 1 is essentially formed by a strip body 3 of a base material, preferably of thermoplastic material. In the embodiment, it is a transparent plastic. On the back of the last body 3, a decorative coating 4 is arranged, the z. B. may be formed by a decorative sheet or a decorative print. The decor of this decorative coating 4 is visible from the front of the bar 1 through the transparent strip body. The edging strip 1 shown thus corresponds in its basic structure to a known "3D edge." Fig. 1 shows this edging strip 1 in the unassembled and not yet machined state The strip has a width B and the strip body points (without the back side Decorative coating) a thickness D on.

According to the invention, 3 slats 5 are integrated into the strip body. These slats 5 are distributed over the width B of the bar and they extend in the longitudinal direction L of the bar. In the exemplary embodiment, the slats extend over the (total) thickness D of the strip. They are obliquely arranged at an angle α to the strip base, wherein the strip base is formed by the body formed by the back of the strip 3 surface. In the illustrated embodiment, the angle α is about 45 °. While the strip body 3 consists of a transparent base material, the slats 5 are made of a non-transparent plastic. The

Production takes place z. B. by way of coextrusion. The design with the lamellae 5 according to the invention has the consequence that the back-side decorative coating is visible to varying degrees as a function of the viewing angle. The visual impression of the bar thus depends on the viewing angle.

While Fig. 1 shows the bar in the not yet assembled and not yet processed state, in Fig. 2, a furniture plate or worktop 2 with mounted and processed edge strip 1 is shown. It can be seen in particular that the attached to the furniture panel 2 edge strip 1 was adapted by machining in its width to the thickness d of the furniture panel and that an adjustment of the strip profile is done by a radius machining. Despite this subsequent processing, the described optical effects are retained.

The bar 1 can be fixed to the plate 2 by known methods. Details, such. As hot melt adhesive layers, functional layers and / or primer layers are not shown. 3 shows a modified embodiment in which the back of the strip is not provided with an (opaque) decoration, but in which the transparent strip body 3 gives the view of the furniture plate or worktop 2 arranged underneath. In the furniture panel 2 Leuchtmitttel are integrated, z. B. light emitting diodes 6, so that the edge band 1 is backlit. The lamellar effect causes such a backlight in the installed state on the furniture panel, the passage light is dimmed so that a dazzling effect is avoided or a certain area can be illuminated.

In the production of the edge strip and in particular of the strip body can be used in principle known materials, especially transparent plastics or opaque plastics, z. As PMMA, ABS and / or polycarbonate (PC).
