EP2200478B1 - Edge strip for pieces of furniture - Google Patents

Description

The invention relates to an edge strip for furniture comprising a base body with an attachable to a piece of furniture bottom and an upper side facing away from the underside, wherein the top has at least one sloping to an edge of the top transition section.

Such edge strips are for example from the DE 34 02 923 A1 . EP 1 080 854 B1 or DE 199 40 329 A1 known.

The publication EP 0125336 A1 further discloses a profile or edge strip for the disguise of furniture panels or the like. A rigid strip body of this profile or edge strip has a visual side forming and partially flexible outer zone, which is covered with a decorative film. The strip body comprises two recesses extending in the lengthwise direction of the strip which extend from the strip inside to the strip body so that the width of the strip can be reduced by compressing the recesses. The recesses are slot-shaped and formed with a wedge-shaped cross-section and taper towards the outer zone.

Conventional edge strips are produced so that they are about 2 to 4 mm wider than the thickness of a furniture board. For example, the furniture board has a thickness of 25 mm, while the edge strip has a width of about 28 mm. After gluing the edge strip to the front side of the furniture board, the protruding edge of the edge strip is milled flush with various, known per se, processing machines. As a result, approx. 10 to 20% of the edge strip is processed during post-processing.

Another disadvantage is seen that the processing machine has a large machine length and high investment costs due to the extensive post.

Also, the visual impression is disturbed by the milling, since between the decor of the edge strip and the decor of the furniture board, the base material of the edge strip creates a kind of frame (so-called picture frame effect) on which no decor can be seen.

The invention has for its object to overcome the disadvantages of the prior art, and to provide a correspondingly improved edge trim.

To achieve this object, the invention provides the edge strip for furniture according to the features of claim 1, comprising a base body with an attachable to a piece of furniture underside and a side facing away from the bottom top, the top at least one sloping to an edge of the body transition section wherein the transition section at least partially has a decor, wherein the decor is printed on the base body of the edge strip.

The edge strip according to the invention is already made in the manufacture of the thickness of the piece of furniture and provided in the transition region, which accomplishes a smooth transition between the top of the edge strip and an upper surface of the piece of furniture, with a decor. To adapt to a specific application, no material-removing post-processing of the narrow sides of the edge strip is required, so that the decor is not removed in the transition section and the objectives and objects of the invention defined above are achieved or solved.

In a downstream decorative attachment device with, for example, digital color printing device, the upper side 3, 4 of the edge strip according to the invention is first pretreated in order to improve the adhesion and the receptivity to the decor 5.

For this purpose, the upper side 3, 4 of the main body 1 is subjected to a corona treatment or plasma treatment and / or subjected to an adhesion promoter. Subsequently, a decor 5 is applied over the entire upper side 3, 4 of the base body 1, so that the decor 5 covers the top surface 3, 4 of the base body 1 over the entire surface and concealed. In particular, the decoration 5 extends directly to both upper edges OR of the edge strip. In this case, the base body 1 is sealed. In order to protect the decor 5 against scratches or other mechanical effects, after applying the decoration 5, a clear coat can be applied and cured, for example, by ultraviolet radiation. The edge strip according to the invention is subsequently attached with the bottom 2 to the edge 7 of the piece of furniture 6, for example by gluing or welding, and is arranged so that an edge OR, UR of the base body 1 of the edge strip is flush with the upper edge edge of the piece of furniture 6, ie ends with the top 8 of the piece of furniture 6. On the underside 9 of the piece of furniture 6, if necessary, a slight protrusion arises due to an excess of the edge strip, which is subsequently removed by means of a machined post, so that the edge strip is also flush with the bottom 9 of the furniture panel 6.

In this case, the decor 5 is removed at the lower, longitudinal edge-side visible edge of the edge strip, in particular in the region of the transition section 3. I.d.R. is the bottom 9 of the piece of furniture 6 is not visible, so that the material or decorative removal on the edge strip in the adjacent to the bottom 9 of the piece of furniture 6 transition section 3 is not considered disadvantageous.

In particular, the decor 5 in the transition section 3 on the overhead, longitudinal edge side edge of the edge trim remains unimpaired.
