Description

The present invention relates to a baseboard for arrangement at the transition between a lower wall end and an adjacent floor area, a ceiling strip for arrangement at the transition between an upper wall end and an adjacent ceiling area and a window or door frame insulation strip for arrangement at the transition between window or door frame and building wall or reveal of a building wall and method for producing such a skirting board, such a ceiling molding and such a window or door frame insulation strip.

At the moment, skirting boards, ceiling moldings and window or door frame insulation strips often consist of either plastic or wood.

The EP 1 114 901 B1 shows a core skirting board with a wood-based material core and a hard plastic sheathing, with a wall end profile made of flexible material arranged on the top of the skirting board, the wall end profile consisting of thermoplastic elastomer based on polyolefin, and the wall end profile being integrally formed or welded to the plastic sheathing. A wall end profile and / or a bottom end profile made of flexible, thermoplastic material based on polyolefin is / are molded onto the plastic sheathing. The production of this core skirting board is complex and expensive. Such a skirting board is often perceived as not of high quality.

The WO 2012/058745 A1 shows a skirting board in its figures 9 and 10 and a ceiling skirting board in their figures 13 and 14, which were produced with an extrusion process. In this extrusion process, a material consisting of 40 to 75 percent by weight rice husks, 0.3 to 3 percent by weight of a connecting agent, 2 to 5 percent by weight of a lubricant, 1 to 5 percent by weight of a plasticizer and the rest is extruded from a thermoplastic polymer. This results in an essentially moisture-impermeable and rigid end product.

From the DE 20 2011 001 699 U1 a skirting board profile for the connection points between the wall and the floor, including the main mounting part of the skirting board is known. The skirting board is formed from an agglomerated sheet on the basis of the crumb material of the bark of the cork oak. An outer decorative part of the baseboards in the form of a leaf is made from natural veneer of the valuable tree species. The veneer sheet on the front surface of the baseboard mounting part is mounted up to the surface part in the form of a rounded edge.

It is therefore an object of the present invention to provide a higher-quality skirting board, a higher-quality ceiling molding and a higher-quality window or door frame insulating strip with good insulating properties which can be produced more cost-effectively. Corresponding manufacturing processes that can be carried out quickly and inexpensively are also to be specified.

This object is achieved by the subject matter of the independent claims. Advantageous further developments result from the dependent claims.

The invention relates to a skirting board according to claim 1, a ceiling molding according to claim 4, a window or door frame insulation strip according to claim 7, a method for manufacturing a skirting board, ceiling molding or window or door frame insulation strip according to claim 14 and a method for manufacturing a Skirting board, ceiling molding or window or door frame insulation strip according to claim 15.

A baseboard according to the invention for arrangement at the transition between a lower wall end and an adjacent floor area comprises the features of claim 1.

A ceiling molding according to the invention for arrangement at the transition between an upper wall end and an adjacent ceiling area comprises the features of claim 4.

A window or door frame insulation strip according to the invention for arrangement at the transition between window or door frame and building wall or reveal of a building wall comprises the features of claim 7.

The basic ideas, advantages and embodiments listed below apply accordingly to the skirting board, the ceiling molding and the window or door frame insulation strip. In the further course, it is generally spoken of moldings by which the skirting boards, ceiling moldings and window or door frame insulation strips are meant.

According to a basic idea of the present invention, the skirting / cover strip / insulation strip according to the invention can be permanently and gaplessly attached to the respective transition.

Through the use of a material, a component, preferably a component of 10 to 90%, more preferably a component of 50 to 60%, of a renewable raw material, at least for a part of the visible area of the base body of the bar, the Lastly, lasts have a natural raw material, and secondly, since at least part of the visible area has such a material, the lasts are of higher quality and have higher-quality optical properties and a higher-quality surface than comparable lasts, whose visible areas consist only of plastic .

According to a finding by the inventor, renewable raw materials can be extruded with the addition of at least one further component which ensures cohesion and, after extrusion, are well suited for the requirements of the skirting board / ceiling molding / insulating strip of the type described above.

According to the invention, a considerable amount of petrochemical or similar substances that have to be used for the production of moldings consisting exclusively of hard plastic can be replaced by a renewable raw material. This conserves resources and guarantees environmentally friendly production.

While the skirting board / ceiling molding / insulating strip according to the invention, which comes into contact with water only slightly in the installed state, remains dimensionally stable in the installed state and can fulfill its protective, sealing and optical function, is also Disposal due to the component from a renewable raw material for at least part of the visible area is significantly simplified. Resulting waste from such strips can be disposed of more easily and can decompose in the ground after a manageable period of time, which also makes the strip according to the invention significantly more environmentally friendly with regard to waste disposal.

As an alternative to disposing of such waste, it can also be completely recycled and used for the production, in particular extrusion, of new strips.

In the broadest aspect of the present invention, it is only important that at least a part of the visible area of the base body comprises a material, a component of which, preferably a component of 10 to 90%, more preferably a component of 50 to 60%, is made from a renewable raw material. This includes both the variant that the entire base body has such a material and the variant that only the visible region has such a material and the region behind it has another material, e.g. B. a less expensive plastic, which is not visible in the intended position of the bar, as well as the variant that the base body comprises a first base body area with such a material and a second base body area made of a plastic material, the first and the second Adjacent the main body area so that the first main body area forms part of the visible area of the main body and the second main body area forms one or the further part of the visible area of the main body.

By producing the strips according to the invention by extrusion, extrusion being understood as an umbrella term for coextrusion or trie extrusion, the strips according to the invention can be produced simply, quickly and inexpensively in one work step, and the protruding strips are safe, detachable and permanent with the rest of the strip connected. The cumbersome and cost-intensive provision of several work steps: producing a wood-based material core, enveloping it with a plastic coating, molding on wall and floor end profiles, as is the case with EP 1 114 901 B1 required, can be significantly simplified. A detachment of wall and floor end profiles, as in the EP 1 114 901 B1 the case can be reliably avoided.

The advantages of different materials, in particular environmental friendliness and high quality of the material made from renewable raw materials and inexpensive Production with the additionally used materials can be combined in the production by extrusion.

The strip according to the invention, viewed in cross section, can have an essentially square base body, the end faces forming the shorter sides and the front and rear sides forming the longer sides of the essentially square base body.

The base body can be rectangular or essentially parallelogram-shaped.

As an alternative to this, the base body can taper towards one end face, so that the base body has a smaller width at the tapered end face end than at the opposite end face end. The tapered end face of smaller width can, in the installed state, be removed from the floor area in the case of the skirting board, away from the ceiling area in the case of the ceiling molding and away from the building wall or reveal of the building wall or away from the window or or door frame.

The base body can also be designed without a separate top side and only have a front side, a back side and a bottom side. The base body can have a substantially triangular cross-section, the front side being straight or curved.

With a base body shaped in this way, a good transition to the building wall (plinth and ceiling molding) or to the building wall / reveal of the building wall or to the window or door frame (window or door frame insulation strip) is achieved, where the strip is in each case with a End is pending.

According to a first embodiment, the strip is designed such that the back of the base body points towards the wall or the window or door frame or bears against the wall or the window or door frame. As a result, the back is not visible and can be designed easily and inexpensively.

According to the invention, in the case of a baseboard and insulation strip, a lower protrusion lip is provided on the underside of the base body, in particular on the front end of the underside of the base body, or on the front of the base body, in particular on the lower end of the front of the base body. which is a material that is softer than the material of the base body, in particular a thermoplastic elastomer; and / or there is an upper protrusion lip on the top of the base body, in particular on the rear end of the top of the base body, or on the back of the base body, in particular on the top end of the back of the base body, which is opposite the material the base body has softer material, in particular a thermoplastic elastomer.

According to the invention, a lower protrusion lip is provided on the underside or front of the base body, in particular on the rear end of the underside or front of the base body, or on the back of the base body, in particular on the lower end of the back of the base body. which has a material which is softer than the material of the base body, in particular a thermoplastic elastomer; and / or an upper protrusion lip can be provided on the top of the base body, in particular on the front end of the top of the base body, or on the front of the base body, in particular on the top end of the front of the base body, which is opposite the Material of the base body has softer material, in particular a thermoplastic elastomer.

Unevenness in the wall, floor, ceiling, reveal or window or door frame can be compensated for and sealed off by the extension lip (s), the respective transition can thus be well protected and thermally insulated by the strip.

The protruding lips, which can be produced together with the base body by way of coextrusion, if the base body has only one material area, and by means of trie extrusion, if the base body has two different material areas, ensure that the strip is in the respective intended position At the respective transition - with a skirting board to the lower wall end and adjacent floor area, with a ceiling skirting board to the upper wall end and adjacent ceiling area and with an insulating bar to the window or door frame and building wall or reveal of a building wall - a reliable seal is guaranteed and moisture or dirt penetrate reliably and permanently prevented in this transition.

At this point it is emphasized that the term lip according to the present patent application does not imply that it must be thin. The Wegrag lip must be designed in such a way that it rests on the respective surface in the intended position of the strip, thus ensuring a reliable seal as well as reliably and permanently prevents moisture or dirt from entering this transition. A bulge-like design of the Wegrag-lip with a large width, based on the length of the Wegrag-lip, as well as a design of the Wegrag-lip with only a slight taper towards the end of the Wegrag-lip also form a Wegrag-lip in the The meaning of the present patent application.

The strip can be designed such that the entire base body has a material, of which a component, preferably a component of 10 to 90%, more preferably a component of 50 to 60%, is made from a renewable raw material. Due to the fact that the base body is thus uniformly made of one material, such a strip can be produced quickly and inexpensively. Such a bar can be manufactured and disposed of in a particularly environmentally friendly manner.

According to the invention, the strip according to the invention is designed such that the base body has a first base body region which has a material, a component of which, preferably a component of 10 to 90%, further preferably a component of 50 to 60%, is made from a renewable raw material, and comprises a second main body region made of a plastic material, the first and the second main body region adjoining one another such that the first main body region forms part of the visible region of the main body and the second main body region forms one or the further part of the visible region of the main body.

As a result, a less expensive material than that for the first main body region can be used for the material of the second main body region, eg. B. a plastic such as PVC, which makes the bar particularly inexpensive, while at the same time being of high value, which is largely determined by the first basic body area. The materials used for the first and second basic body areas have very good insulating properties. With the aid of the interface welding in the case of production by extrusion, in particular by coextrusion or, if additional protruding lips are additionally provided, by trie extrusion, the first and the second basic body region are securely connected to one another.

Because the visible area comprises both a first base body area with a material, a component of which is a renewable raw material, and a second base body area made of a plastic material, different surface properties result for one and the same bar in the visible area and optical properties, which are particularly advantageous when two different materials adjoin one another at the transition at which the respective strip is arranged, e.g. B. at a transition between the lower wall end and the adjacent floor area (skirting board), building wall and wood, in particular parquet or laminate flooring or at the transition between the upper wall end and the adjacent ceiling area (ceiling molding), building wall and z. B. a wooden ceiling or at the transition between window or door frame and building wall or reveal of a building wall (ceiling molding) wood or plastic and building wall.

According to a further embodiment, the interface between the first and the second basic body region extends from the front to the rear of the basic body of the strip.

The interface can in particular run essentially horizontally from the front to the back and divide the bar into two substantially identical main body areas. Likewise, other z. B. inclined or stepped interfaces or a position of the interface possible such that the base body areas have a different relationship to each other, for. B. a ratio of 1/3 to 2/3, from 1/4 to 3/4 or the like.

According to a further embodiment, when the skirting board is arranged at the transition between the lower end of the wall and the adjacent floor area, the first base area forms the section of the skirting board facing the floor area, and the second area forms the section of the skirting board facing away from the floor area .

With these embodiments, the transition between the lower end of the wall and the adjoining floor area, in the case of a skirting board, between the upper end of the wall and the adjoining ceiling area, in the case of a ceiling molding and the transition between the window or door frame or building wall or the reveal of a building wall, in the case of an insulating strip, visually to the interface be laid between the first and the second body area of the bar, which gives a visual advantage and a more attractive and cleaner appearance, since dust or dirt particles that are at the transition between the floor area and skirting board or ceiling area and ceiling molding or window or Collect door frame and insulation strip or stick there, visually less well perceived.

According to a further embodiment, when the ceiling strip is positioned at the transition between the upper wall end and the adjacent ceiling area, the first basic body area forms the section of the ceiling strip facing the ceiling area, and the second basic body area forms the section of the ceiling strip facing away from the ceiling area .

According to a further embodiment, in a position of the window or door insulating strip at the transition between the window or door frame and the building wall or reveal of a building wall, the second basic body region forms the section of the insulating strip facing the window or door frame, and the first The main body area forms the section of the insulation strip facing away from the window or door frame.

According to the invention, the strip is designed in such a way that the visible area of the base body is formed by a narrow cover element, that the base body furthermore has an insulating body section which is arranged behind the narrow cover element and bears against the cover element or is connected to it by interface adhesion or interface welding and that the narrow cover element comprises a material, of which a component, preferably a component of 10 to 90%, more preferably a component of 50 to 60%, is made from a renewable raw material.

As a result, a less expensive material than the cover element can be used for the material of the insulating body section, e.g. B. recycled plastic, especially PVC, which makes the bar particularly inexpensive, while at the same time high value, which is determined by the cover element. The materials used for the insulating body section and for the cover element have very good insulating properties. With the help of the interface welding in the case of production by extrusion, in particular trie extrusion, the narrow cover element and the insulating body section are securely connected to one another.

According to a further embodiment, the strip according to the invention is designed in such a way that the narrow cover element has an angular cross-sectional profile, the first, in particular shorter, leg of which forms the upper side of the base body or, in the case of the cover strip, the lower side of the base body and the second, in particular longer leg, which forms the front side of the base body. This ensures that the narrow, high-quality cover element forms the entire field of view of the strip according to the invention.

According to a further embodiment, the strip according to the invention is designed in such a way that the narrow cover element has an anchoring leg which attaches to the end of the second, in particular longer leg, which is remote from the first, in particular shorter leg. By means of this anchoring leg, the narrow cover element and the insulating body section are connected to one another in a particularly secure and permanent manner.

According to a further embodiment, the strip according to the invention is designed in such a way that the base body in its lower region or, in the case of the ceiling strip, in its upper region forms a region that is bent forwards. The area bent forward has an angle of between 10 and 45 °, starting from the vertical back plane of the base body. As a result, the bar can be positioned well, even if the transition from floor to wall or from ceiling to wall or from window or door frame to building wall or reveal of a building wall is not at right angles.

According to a further embodiment, the strip according to the invention is designed in such a way that the protruding direction of the protruding lip encloses an angle of 30-60 ° with the plane of the front of the base body or with the level of the rear of the base body. Such a protruding lip provides a particularly good seal.

According to a next embodiment, the strip according to the invention is designed such that the upper Wegrag-lip and / or the lower Wegrag-lip have a material, of which a component, preferably a component of 10 to 90%, further preferably a component of 50 to 60%, is from a renewable raw material. Such a strip is particularly high quality and environmentally friendly to manufacture and dispose of.

According to one embodiment of the invention, the component of the material consists of rice husks or fibers or flour made of it, or of wood or fibers or flour made of it.

A so-called wood plastic composite has proven to be particularly advantageous as a material.
