Definitions

• the invention relates to a sealing element for a lightweight board, a lightweight board with at least one cutout and a use of a sealing element.
• Lightweight panels are well known in the art. Also in furniture and interior design, these are used for a long time in a variety of ways. The main field of application was and is the door construction here. So it is especially in room doors, which are therefore subject to low requirements in terms of heat and sound insulation, usually a frame member with a honeycomb core on both sides to plank and this then continue to process the corresponding holes, millings, etc. to a door element.
• the manufacturer of furniture does not need to manufacture lightweight panels today, as was the case earlier.
• Several operations were necessary.
• a frame had to be made, possibly with several crossbars on which then the cover layers were applied and who had to take the various fittings.
• cover layers lightweight fiber boards, mineral insulating wool, cardboard honeycomb or the like were introduced. This gave the item more compactness and possibly improved stability.
• the outer layers also had to be elaborately surface-treated in separate operations. For example, veneered or otherwise coated hardboards were used as cover layers, and the finished element can only be given its final surface by final painting.
• cover plates Today, lightweight panels are increasingly being manufactured industrially.
• a light middle layer is provided with cover plates, usually by gluing, so that a large-format, frameless composite arises.
• cover plates mostly from a wood material such as chipboard or fiberboard used.
• the plates used may already be coated, that is to say be provided with a laminate, a paint, a pressure with a seal, a melamine resin layer, a veneer, etc.
• cardboard honeycomb or foam boards are preferred.
• Honeycomb materials made of materials other than paper or cardboard may also be useful for certain purposes. For example, the thinnest sheet materials or even thin-walled metal such as aluminum can be used.
• middle layers of light wood materials such as corresponding chipboard or fiberboard or solid wood low density, such as balsa wood.
• corresponding recesses are basically all materials for use as a light middle layer possible.
• wood species are used for that, although not particularly low weight, but are well available and can be easily edited with cutting tools.
• the plates thus produced are then divided into the desired size. Depending on the intended use of the resulting elements, these are then provided with edges or an at least partially encircling frame is subsequently introduced. This is done by milling the edge area and subsequent gluing a frame profile, which in turn consists mostly of a wood material.
• Cutouts are necessary, for example, when using a lightweight board as a kitchen worktop to accommodate a sink or a stove top.
• the invention is therefore based on the technical problem of providing measures that allow protection of narrow surfaces and middle layers in a simple and individual way.

• the narrow surfaces and / or the middle layer in particular by moisture, deform adversely, discolor or develop undesirable properties in any other way.
• the inner section projects in the direction of the central position relative to the outer section. In this way, the inner portion can be inserted during assembly between the cover plates, which increases the sealing effect and stability.
• the inner section has at least one projection, preferably two projections, which projects in the direction of the central position relative to the outer section.
• at least one of the projections have a latching nose, which cooperates with a corresponding recess in the cover plate.
• the recesses are provided on the inside of the cover plate and the latching lugs are away from one another. This forms a clip connection which allows for easy assembly and disassembly of the sealing element.

• a groove / spring connection also provides a simple way to assemble and disassemble the sealing element.
• the sections can be made of an elastic material
• an outer portion is given, which applies very well especially in round cutouts or in cutouts with rounded edges on the narrow surfaces and thus seals very well.
• the inner portion can thereby be used non-positively in the recess of the middle layer and between the cover plates.
