Description

[0001] The invention relates to a skirting board for arrangement at a building transition between a lower wall end and an adjacent floor area.

[0002] Skirting boards that are arranged at a building transition between a lower wall end and an adjacent floor area are known, for example, from EP 3 795 775 and from DE 10 2014 115 656 A1.

[0003] Tests with such baseboards have shown that if these baseboards, when installed, come into contact with, for example, a Bunsen burner flame, they will ignite after some time. Since such baseboards are often freely accessible from inside the room, they pose a fire hazard, especially if they are made of a highly or normally flammable material, which is frequently the case.

[0004] DE 10 2008 046481 A1 discloses a composite material comprising 10-50 parts by weight of natural fibers, 15-40 parts by weight of at least one thermoplastic or thermoplastic polymer, 10-30 parts by weight of at least one flame retardant, preferably halogen-free compounds, and 1-5 parts by weight of at least one further additive, preferably a lubricant. The amount of lubricant is limited such that the composite material reinforced with natural fibers has a modulus of elasticity of at least 3,500 MPa according to DIN ISO 527.

[0005] From EP 1 669 513 A1, a finishing device and a method for finishing a room are known. The room comprises a transition area between a first area and a second area. The method comprises connecting a finishing device to the transition area, wherein the finishing device comprises at least one end section extending to the first area and at least one finished surface, and covering the first area and the at least one end section with covering material, such that at least a part of the finished surface lies in the same plane as and adjoins at least a part of a front surface of the applied covering material.

[0006] US Patent 2007 / 020475 A1 discloses a substrate primed to receive a coating or other decoration, and a method for its preparation. A substrate is primed with a viscous coating material containing 50 to 95 percent by mass of solid material to fill surface pores and cover the substrate surface with a dense layer of coating material, so that a single coat of paint provides a uniformly rich color and gloss.

[0007] From DE 10 2005 044463 A1, a strip, in particular a wall, ceiling or floor trim strip, is known which has a support strip and a cover layer bonded to the support strip by full-surface bonding with an adhesive. The support strip, cover layer and adhesive have a flash point of at least 200°C and an ignition temperature greater than 300°C.

[0008] DE 10 2020 113238 A1 discloses a plastering strip for placement at a building transition between a first building component designed as a window or door frame and a second building component, in particular thermal insulation and / or a plaster layer, the use of a reinforcing mesh section in a plastering strip for placement at such a building transition and a building transition with such a plastering strip.

[0009] It is therefore an object of the present invention to provide a skirting board in which the risk of ignition is reduced, while maintaining full functionality and without impairing the appearance of the skirting board.

[0010] This problem is solved by the subject matter of the independent patent claims. Advantageous further developments result from the dependent patent claims.

[0011] A baseboard according to a first embodiment of the present invention comprises the features of independent claim 1.

[0012] A baseboard according to a second inventive variant of the present invention comprises the features of independent claim 6.

[0013] A baseboard according to a third inventive variant of the present invention comprises the features of independent claim 9.

[0014] In the first embodiment of the invention, at least one lower termination element is provided on the underside of the base body, in particular at the front end of the underside of the base body, and an upper termination element is provided on the top side of the base body, in particular at the front or rear end of the top side of the base body, and at least one part thereof has a material which is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or into fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0015] According to the second variant of the present invention, the base body comprises a material which is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or into fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0016] According to the third variant of the present invention, the skirting board comprises a casing that at least partially surrounds the base body, or a front cover that surrounds at least the visible side of the base body, in particular at least the front and optionally the top, and the casing or cover has a material that is provided with a flame retardant, such that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or into fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0017] The common technical principle connecting all three invention variants is to achieve an improvement in the fire protection class for the combination of material and flame retardant by adding a flame retardant to the respective material, namely fire protection class B2 "normally flammable" or fire protection class B1 "difficult to ignite".

[0018] In the first embodiment of the invention, the material that is / will be provided with a flame retardant is the material of at least one part of the lower end element and / or the upper end element; in the second embodiment, the material that is / will be provided with a flame retardant is the material of the base body; and in the third embodiment, the material that is / will be provided with a flame retardant is the material of the casing or cover. The material can also be referred to as the base material in each case.

[0019] In all three invention variants, an essential component of the baseboard is thus brought into a better fire protection class by the addition of a flame retardant, thereby significantly reducing the risk of ignition.

[0020] According to an insight underlying the invention, the inventors had previously paid little or no attention to the flammability risk of baseboards; instead, the focus had been on other building components, such as the facade or electrical systems, and their flammability. For a relatively low-value product like a baseboard, it would have been inconceivable to a person skilled in the art at the filing date of the present patent application to consider it with regard to fire protection.

[0021] The reduction of the risk of ignition according to the invention is relevant both for the delivered state and for the installed state of the skirting board, e.g. if, unintentionally, part of the skirting board in the interior of the building comes into contact with a flame.

[0022] By reducing the fire protection class B2 "normally flammable" according to the specified DIN standard in all three invention variants to at least the lower and / or upper end element of the skirting board in invention variant 1, the base body in invention variant 2 and the casing or cover in invention variant 3, and by correspondingly reducing the overall risk of ignition of the skirting board, the occurrence or spread of a fire in the delivered state, in the installed state and also during the installation phase is effectively counteracted.

[0023] At the same time, the full functionality of the skirting board – "thermal decoupling of the building transition, protection of the building transition from dirt, moisture and mold and the like, cladding of the building transition" – can be maintained unchanged, and the appearance of the skirting board is not negatively affected by the addition of the flame retardant.

[0024] It should be noted that instead of the fire protection classes B1 "flame-resistant" and B2 "normally flammable" used according to the invention, the corresponding classes and the required tests for fire behavior from the European standard EN13501-1 can also be used as a reference.

[0025] The fire protection class B1 according to DIN standard 4102-1 corresponds to the following classes of EN standard 13501-1: B; C-s1, d0 A2; B; C-s2, d0 A2; B; C-s3, d0 A2; B; C-s1, d1 A2; B; C-s1, d2 A2; B; C-s3, d2

[0026] The fire protection class B2 "normally flammable" of DIN standard 4102-1 corresponds to the following classes of EN standard 13501-1: D-s1, d0 D-s2, d0 D-s3, d0 D-s1, d1 D-s2, d1 D-s3, d1 D-s1, d2 D-s2, d2 D-s3, d2 E E-d2

[0027] The fire protection class B1 "flame-resistant" means that the ignitability in the event of edge or surface exposure with a small flame remains limited to the level specified in DIN 4102-1.

[0028] The fire protection class B2 "normally flammable" means that the fire will extinguish itself after the fire source has been removed.

[0029] With regard to DIN standard 4102-1, the skirting board according to the invention is to be considered a building material within the meaning of 6.1.1 a). The test, which is described in detail in this DIN standard under 6.1.3.1, represents, as a model, the burning of an object in a room (e.g., a wastebasket in a corner of a room). Under this stress, the spread of the fire must not extend significantly outside the primary fire area, and the heat emission must be limited.

[0030] According to section 6.1.2.1 of DIN standard 4102-1, skirting boards according to the invention, which are to be regarded as building materials, excluding floor coverings, meet the requirements for classification in building material class B1 if they pass the fire shaft test and meet the requirements for building material class B2.

[0031] According to section 6.1.2.2 of DIN standard 4102-1, the fire shaft test is considered passed if, during a test according to section 6.1.3.1 a) the mean residual length (according to 9.1 of DIN 4102-16: 1998-05) of each test specimen is at least 15 cm and no specimen has a residual length of 0 cm, b) the mean flue gas temperature does not exceed 200°C in any test, c) the specimens only continue to burn, glow with flame or smolder to the extent that the requirement for the residual length is met.

[0032] For further details regarding the testing for building material class B1, please refer to sections 6.1.3 and 6.1.4 of DIN standard 4102-1.

[0033] Skirting boards according to the invention fall into building material class B2 if, under stress from a small, defined flame (match flame), the ignitability and the flame spread are limited within a certain time, see 6.2.1 of DIN standard 4102-1.

[0034] The application of flame retardant to the corresponding material of the lower / upper end element of the baseboard (invention variant 1), the base body (invention variant 2) and the sheathing or cover (invention variant 3) can be carried out or implemented in different ways, as will be explained in detail below, e.g. the flame retardant can be incorporated into the material / base material, it can also be applied as a layer, in particular sprayed, brushed, painted or rolled on.

[0035] In the first version of the invention, tests have shown that, since the lower / upper end element closes the gap to the floor and the lower end of the wall in the installation position of the baseboard, a reduction in the risk of ignition at this point alone already brings about a significant improvement.

[0036] In the first variant of the invention, the embodiments are included in which only a lower termination element, only an upper termination element, or both a lower and an upper termination element are present as indicated and are provided with a flame retardant according to the invention.

[0037] According to a first embodiment of the first variant of the invention, at least a partial area of ​​the lower termination element and / or the upper termination element comprises a material that inherently falls into fire protection class B2 "normally flammable" according to DIN standard 4102-1: 1998-05, and the material is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0038] Alternatively, at least a portion of the lower termination element and / or the upper termination element has a material that inherently falls into fire protection class B3 "highly flammable" according to DIN standard 4102-1: 1998-05, and the material is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or into fire protection class B1 "low flammability" according to DIN standard 4102-1: 1998-05.

[0039] Thus, by adding the flame retardant, an improvement to the next better fire protection class is achieved, either from fire protection class B2 "normally flammable" to fire protection class B1 "difficult to ignite" or from fire protection class B3 "easily flammable" to fire protection class B2 "normally flammable".

[0040] In particular, if the material of at least one part of the lower / upper termination element inherently falls into the unfavorable fire protection class B3 "highly flammable", the addition of flame retardant according to the invention and the corresponding improvement of the fire protection class of the combination of material and flame retardant to fire protection class B2 "normally flammable" or even to the even better fire protection class B1 "difficult to ignite" achieves a very significant reduction in the risk of ignition.

[0041] According to a further embodiment of the first variant of the invention, the lower termination element and / or the upper termination element is a lip, in particular a sealing lip, or a bead, in particular a sealing bead. A bead is understood to be an accumulation or shape of the material of the corresponding termination element that is wider than it is high / long, up to an equal width-to-height-length ratio.

[0042] Accordingly, a lip is understood to be an accumulation or shape of the material of the corresponding finishing element that is higher / longer than it is wide.

[0043] According to a further embodiment of the first variant of the invention, the lower end element and / or the upper end element comprises a tip and a rear section, the rear section being directed towards the base body and away from the tip. The portion of the lower / upper end element provided with a flame retardant is formed by the tip. In other words, the tip comprises a material provided with a flame retardant, such that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0044] According to an alternative embodiment of the first variant of the invention, the entire lower termination element and / or the entire upper termination element comprises a material provided with a flame retardant, such that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or into fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0045] A baseboard according to the second variant of the invention, as defined in independent claim 6, can, according to a first embodiment, further comprise at least one lower termination element on the underside of the base body, in particular at the front end of the underside of the base body, and one upper termination element on the top side of the base body, in particular at the front or rear end of the top side of the base body.

[0046] The embodiments include those in which only a lower termination element, only an upper termination element, or both a lower and an upper termination element are present as indicated and are provided with a flame retardant according to the invention.

[0047] According to one embodiment of the second variant of the invention, at least a partial area of ​​the lower termination element and / or the upper termination element can have a material that is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or into fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0048] Thus, the improved flame protection effect and the reduced risk of ignition can be extended beyond the main body to the lower and / or upper finishing element, resulting in such an improved flame protection effect and a reduced risk of ignition for the entire skirting board.

[0049] According to an alternative embodiment, the lower / upper end element can also be made of a material other than the one provided with a flame retardant according to the invention.

[0050] In the case of the skirting board according to the second variant of the invention, as defined in independent claim 6, a particularly good flame-retardant effect and a particularly effectively reduced risk of ignition result, because the entire base body and, if applicable, at least one of the lower and upper termination elements is made of a material provided with a flame retardant, so that the combination of material and flame retardant falls into the favorable fire protection class B2 "normally flammable" or into the even more favorable fire protection class B1 "flame-retardant" according to the specified DIN standard.

[0051] According to a further embodiment of the skirting board according to the second variant of the invention, the base body has a material that inherently falls into fire protection class B2 "normally flammable" according to DIN standard 4102-1: 1998-05, and the material is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0052] According to a further embodiment of the skirting board according to the second variant of the invention, the base body has a material that inherently falls into fire protection class B3 "highly flammable" according to DIN standard 4102-1: 1998-05, and the material is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or into fire protection class B1 "low flammability" according to DIN standard 4102-1: 1998-05.

[0053] In the case of the skirting board according to the third variant of the invention, as defined in independent claim 9, a very effective increase in the flame-retardant effect and a very effective reduction in the risk of ignition are also achieved according to the invention, especially since the sheathing or the covering, which usually represent the areas that come into contact with a flame, have been adapted by adding a flame retardant to their material in such a way that the combination of material and flame retardant falls into the favorable fire protection class B2 "normally flammable" or into the even more favorable fire protection class B1 "flame-retardant" according to the specified DIN standard.

[0054] According to a first embodiment of the third inventive variant of the baseboard, a lower termination element is provided on the underside of the base body, in particular at the front end of the underside of the base body, and the cover can also extend over the visible side of the base body, in particular over the front of the base body, and in particular over at least a part of the front of the lower termination element.

[0055] According to a first embodiment of the third variant of the invention of the baseboard, an upper termination element is provided on the top of the base body, in particular at the front end of the top of the base body, and the cover can also extend over the visible side of the base body, in particular over the front of the base body, and in particular over at least a part of the front of the upper termination element.

[0056] It can therefore be provided with a lower end element and an upper end element, and the cover can extend not only over the visible side of the base body but also over at least a part of the front surface of the respective lower or upper end element. The advantages correspond to those stated above with reference to the first embodiment of the invention.

[0057] In an alternative embodiment, both a lower and an upper end element can be present, and the cover can extend, in addition to the visible side of the base body, particularly also over at least a portion of the front surface of the lower and upper end elements. The advantages correspond to those stated above with reference to the first embodiment of the invention.

[0058] According to a further embodiment of the third variant of the invention of the baseboard according to the invention, the covering extends over the visible side of the base body, in particular over the front and possibly the top of the base body, and at least partially over the underside, in particular its front end area, and the back of the base body, in particular its upper end area.

[0059] At least one lower termination element can be provided on the underside of the casing, in particular at the front end of the underside of the casing, and at least one upper termination element can be provided on the top side of the casing, in particular at the rear end of the top side of the casing. The advantages correspond to those stated above with reference to the first embodiment of the invention.

[0060] According to a further embodiment of the third variant of the invention, the casing or cover has a material that inherently falls into fire protection class B2 "normally flammable" according to DIN standard 4102-1: 1998-05, and the material is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B1 "flame-retardant" according to DIN standard 4102-1: 1998-05.

[0061] According to a further embodiment of the third variant of the invention, the casing or cover has a material that inherently falls into fire protection class B3 "highly flammable" according to DIN standard 4102-1: 1998-05, and the material is provided with a flame retardant, so that the combination of material and flame retardant falls into fire protection class B2 "normally flammable" or into fire protection class B1 "low flammability" according to DIN standard 4102-1: 1998-05.

[0062] According to a further embodiment, which applies to the baseboards of all specified invention variants, the material or base material of the lower and / or upper end element (1st invention variant), the base body (2nd invention variant), or the material of the cover / sheathing (3rd invention variant) is selected, in particular, from one of the following materials: a plastic, in particular a rigid plastic, especially polypropylene (PP), polystyrene (PS), polyethylene (PE) or rigid PVC; a foamed plastic; polyurethane (PUR); a flexible plastic, in particular a thermoplastic elastomer (TPE) or flexible PVC; elastomers, in particular foamed elastomers, especially based on rubber, neoprene rubber, ethylene propylene diene monomer (EPDM) rubber; a plastic mixture of different plastics, in particular a rigid PVC + water-PVC mixture or a PP + TPE mixture; a mixture of plastic, in particular PVC, PP, PS, PU, ​​PE and mineral material; thin wood, in particular solid wood or wood wool;a fiberboard containing wood, in particular a medium-density fiberboard or medium-density fiberboard, also known as MDF, a UL-MDF, an L-MDF, a high-density fiberboard (HDF), a hard fiberboard (HB), a medium-hard fiberboard (MB, MBL, MBH), a plastic-faced flat-pressed board or melamine-faced board (MFB), a particleboard or oriented strand board (SB, OSB); and a plastic composite, e.g., a wood-plastic composite or a rice husk-plastic composite.

[0063] A skirting board according to the invention can be manufactured in various ways.

[0064] One option that is well suited to all three invention variants is production by extrusion or co-extrusion, which can be chosen particularly when manufacturing from one or more plastic materials. In this process, the flame retardant is added to the material / base material before / during the extrusion process, and accordingly, the flame retardant is contained and distributed within the material / base material.

[0065] Alternatively, it is possible, for example, to spray, paint or coat a material core made of plastic, wood, a fiberboard with wood, or a plastic composite material, as indicated above, with a flame retardant, which is particularly suitable for the first variant of the invention.

[0066] According to a further embodiment of the invention, which is applicable to all the invention variants described above, the flame retardant is designed as a halogenated flame retardant, a nitrogen-based flame retardant, an organophosphorus flame retardant, or an inorganic flame retardant.

[0067] According to a further embodiment of the invention, which is applicable to all the invention variants described above, the flame retardant is designed as an additive flame retardant, which is incorporated as an additive into the material of the lower end element and / or the upper end element, into the material of the base body or into the material of the casing or cover of the base body.

[0068] According to a further embodiment of the invention, which is applicable to all the invention variants described above, the flame retardant is designed as a reactive flame retardant.

[0069] According to a further embodiment of the invention, which is applicable to all the invention variants described above, the flame retardant is designed as a coating which is applied externally to the lower end element and / or the upper end element, externally to the base body or externally to the casing or cover of the base body, in particular by spraying, brushing, extruding or overmolding.

[0070] The invention is explained in more detail below with reference to exemplary embodiments and the accompanying figures.

[0071] Figure 1 shows side views of six different baseboards according to six embodiments of the present invention, wherein only the base body of the first baseboard is shown. Figure 1 (a) is equipped with an upper and lower connecting element and the base bodies of the other skirting boards are made from the Figures 1 (b) to (f)are designed without connecting elements.

[0072] Figure 2 shows side views of seven different baseboards according to seven further embodiments of the present invention ( Figures 2 (a) to (g) ), in which an upper and a lower finishing element are arranged on the base body of the skirting board.

[0073] Figure 3 shows side views of six different baseboards according to six further embodiments of the present invention, each of which has a cover ( Figures 3 (a), (b) and (c) ) or each a sheathing ( Figures 3 (d), (e) and (f) is provided for, and each includes an upper and a lower finishing element ( Figures 3 (a) to (f) ).

[0074] In the Figures 1 (e) and (f) The skirting boards shown are depicted in their installed state. Such skirting boards can, for example, be made entirely of soft material and delivered coiled.

[0075] For all others in the Figures 1 (a), (b), (c), and (d) as in the Figures 2 and 3 The skirting boards shown are depicted in their delivered state.

[0076] The installation state at a building transition between a lower wall end and an adjacent floor area can be easily imagined by imagining that the respective baseboard, with its back facing left in the plane of the drawing, rests against the front of the lower wall end and either rests on the floor area with the underside of its main body or with the underside of its lower end element.

[0077] The front side is shown facing right in the plane of the drawing and, in the installed position, points into the interior of the room.

[0078] At the in Figure 1(a)The baseboard 2 shown has a rectangular cross-section with a longer right front, a longer left back, a shorter top, and a shorter bottom. The front and back extend parallel to each other, as do the top and bottom.

[0079] At the transition between the front and the top, an upper end element 6, designed as an upper projecting lip, is positioned. This upper projecting lip extends obliquely backwards at an angle of 30 to 80°, in the present embodiment approximately 50°, relative to the vertical plane of the front of the base body 4. The length of the upper projecting lip 6 is selected such that, in the delivery state of the baseboard 2 shown here, the upper rear tip of the upper projecting lip 6 lies a short distance behind the vertical plane formed by the rear of the base body 4 of the baseboard 2.

[0080] At the transition area between the front and the underside, a lower end element 8, designed as a lower projecting lip, is arranged. This element projects at an angle of 30 to 80°, in the present embodiment at an angle of approximately 45°, relative to the vertical plane of the front of the base body 4. In the present, non-limiting embodiment, the lower projecting lip 8 has a slightly curved profile.

[0081] The Wegrag lips 6 and 8 may exhibit a tapering width, particularly when viewed towards their tip.

[0082] The front lower tip of the lower projecting lip 8 is offset forward relative to the plane of the front of the base body 4, in particular by approximately 2 to 3 times the width of the base body 4, viewed from the back to the front. Likewise, the front lower tip of the lower projecting lip 8 is offset downward relative to the plane of the underside of the base body 4 of the skirting board 2, in particular by approximately 1 to 3 times the width of the base body 4, viewed from the back to the front. These values ​​are, of course, only examples; other dimensions are also possible, e.g., 0.2 to 3 times the width of the base body 4.

[0083] The in Figure 1(b) The skirting board 10 shown is designed without top and bottom end caps. The base body 4 has a rectangular cross-section with longer front and back sides and shorter top and bottom sides.

[0084] The following Figures 1(b) to (f) The skirting boards shown 10, 12, 14, 16 and 24 each have a basic body, but are designed without an upper and lower finishing element.

[0085] The basic body 4 of the in Figure 1(c) The skirting board 12 shown has a parallelogram-shaped cross-section with longer front and back sides and shorter top and bottom sides. The top and bottom sides are inclined downwards from the back to the front and form an angle with the floor plane of 1° to 50°, in the present embodiment of approximately 20°.

[0086] The basic body 4 of the in Figure 1(d)The skirting board 14 shown has a triangular cross-section with a sloping front, a substantially vertical back, and a bottom, wherein, in this non-limiting embodiment, a right angle is formed between the back and the bottom. The sloping of the front relative to the vertical plane of the building wall results from the height of the skirting board. This angle is typically between 5° and 30°; in this embodiment, it is approximately 12°.

[0087] The basic body of the in the Figures 1(e) and (f)The skirting boards 16 and 24 shown each have a 1-shaped cross-section and are divided into a vertical base section 18, the rear of which rests against the front surface of the wall when installed; a horizontal lower support section 20, with which the skirting board 16, 24 rests on the floor; and an integrally formed, curved transition or connecting section 22, which connects the sections 18 and 20. The transition section 22 is tapered or has a reduced material thickness compared to the material thicknesses of the base section 18 and the support section 20, as shown in Figure 1(e) continuously rejuvenated and in Figure 1(f) It is designed with a stepped, tapered design.

[0088] The flexible transition section 22 allows the baseboard 16 and 24 to be adapted to the installation situation, and a tight seal can also be achieved in installation situations other than right angles.

[0089] The upper end of the vertical base body section 18 and the front end of the base body support section 20 can be curved forwards or upwards to avoid an edge and to form a continuous transition to the wall area or the floor area at this point.
