Description

[0001] The invention relates to a facade cladding profile comprising a base profile having hollow chambers, made of a first plastic, preferably of a first extruded plastic, wherein the base profile has a surface which is provided with a surface coating to form a visible surface, and wherein a plug-in area is formed on one side of the base profile, located laterally next to its surface and recessed in level with the surface, in particular which can be plugged into a receiving area of ​​an adjacent facade cladding profile, and wherein a receiving area, preferably a receiving area located below its surface, is formed on the other side of the base profile, in particular into which a plug-in area of ​​an adjacent facade cladding profile can be plugged at least partially, and wherein a shadow gap surface made of a second plastic is formed on a partial area of ​​the plug-in area.which is bonded to the first plastic of the base profile, preferably by co-extrusion.

[0002] In this context, an element produced by co-extrusion, such as a shadow gap surface, is understood to be an element that is created simultaneously with the base body, which is also produced by extrusion, through the co-extrusion process.

[0003] The aforementioned other side is the opposite side, so that on the facade cladding profile the insertion area and the receiving area are arranged parallel to each other and each running in the extrusion direction of the profile.

[0004] A shadow gap surface is preferably understood to be a surface that forms the base of the joint in a shadow gap, which is lower in level than the visible surface, in particular which lies below the visible surface with a height difference, preferably which is formed parallel to the visible surface.

[0005] The shadow gap surface of the aforementioned insertion area forms the base of a shadow gap between two adjacent facade cladding profiles when these are connected via the insertion area and the receiving area. The insertion area is preferably received in a groove of the receiving area of ​​another facade cladding profile by means of an element designated as a spring element. Other areas of the insertion area, located next to the spring element, are preferably situated, after connection, at least beneath the receiving area of ​​the other facade cladding profile.

[0006] Such a facade cladding profile or panel made of plastic is preferably a single piece with respect to the base profile and can be manufactured into profile form by continuous casting or extrusion. Thermoplastics, in particular PVC (polyvinyl chloride), are preferably used as the plastic material for the base profile. PVC is also used, for example, in window frame construction or for pipes.

[0007] During manufacturing, the PVC material, preferably in granular form, is thermally melted and pressed through a mold. The PVC cools slowly and retains its shape. The molds can have a wide variety of contours. Typically, a basic profile has hollow chambers enclosed by webs, with a constant cross-section in the longitudinal / extrusion direction.

[0008] Facade cladding profiles are known from the state of the art. These are used, for example, for cladding the facades of buildings or mobile homes.

[0009] To fix the facade cladding profiles to the wall of a building, a substructure, e.g. made of wood, is provided on the wall of the building, on which the facade cladding profiles, in particular those that can be several meters long, are attached.

[0010] The insertion area may preferably have several openings arranged one behind the other in the longitudinal direction, particularly in a fastening area, which serve to accommodate fastening means, e.g. nails or screws, by means of which the individual facade cladding profiles made of plastic can be fastened to the substructure on the wall, for example of a building.

[0011] The plug-in area not only serves to connect the facade cladding profiles to the substructure on the wall of a building, but also allows two such facade cladding profiles to be connected to each other in the manner of a tongue and groove connection through the plug-in area and a corresponding receiving area.

[0012] For this purpose, the insertion area, which can be functionally designed as a fastening strip and in particular includes a spring element, extends along the length of the facade cladding profile on one side. Correspondingly, a corresponding receiving area runs along the opposite longitudinal side of the facade cladding profile, in particular with a receiving groove for receiving the preferably provided spring element.

[0013] The visible surface of facade cladding profiles can be designed in many different ways. For example, it is known to create the visible surface using foil, especially where the foil is in a desired color and / or has a texture, particularly mimicking the look of a wood surface.

[0014] According to current technology, solid foam profiles with decorative foils applied to them are widely used. The foil surfaces extend continuously over the entire surface, i.e., over the raised visible surfaces and the recessed shadow gap surfaces.

[0015] A facade cladding profile of the type mentioned above is known, for example, from publication DE20 2021 106 311 U1 of the same applicant. This document discloses a facade cladding profile according to the preamble of claim 1. A disadvantage of this construction is that, in this prior art, the film used as a surface coating extends beyond the visible surface, in particular over wall areas sloping downwards from the visible surface, down to the level of the shadow gap surface. By joining two facade cladding profiles, only a single shadow gap is formed, which differs from the optical appearance of the visible surface only in the shadow gap area at the base of the shadow gap, but not in the wall areas of the shadow gap, since these are also covered with the film.

[0016] Therefore, in light of this prior art, it is an objective of the invention to create a construction of a facade cladding profile in which the shadow gap walls also contribute to the optical differentiation from the visible surface, in order to create a more visually dominant appearance of the shadow gap.

[0017] Since customers often desire a high number of shadow gaps in the overall appearance, this necessitates the installation of a correspondingly high number of facade cladding profiles under the aforementioned prior art. Therefore, a further object of the invention is preferably to achieve an increase in the number of shadow gaps while maintaining the same number of facade cladding profiles.

[0018] The invention is a facade cladding profile according to claim 1.

[0019] This design according to the invention results in the shadow gaps formed by joining adjacent facade cladding profiles being made of the same second plastic material, both in their shadow gap surface and in their shadow gap walls. It is provided that each shadow gap wall extends at least to the height level of the surface of the base profile.

[0020] This makes it possible, among other things, to ensure that each shadow gap can be designed completely differently in its optical appearance, i.e., in terms of the shadow gap surface and the shadow gap wall, than the surface coating arranged on the surface of the base profile to form the visible surface.

[0021] In a top view perpendicular to the visible surface, which is defined by the coated surface of the base profile, the shadow gap already appears wider than in the aforementioned prior art. Furthermore, the angle of incidence of light on the shadow gap walls differs from that on the shadow gap surface and the visible surface, further influencing the visual appearance.

[0022] Such a different optical appearance can be achieved, for example, by a different color of the second plastic and / or a different structuring of the second plastic compared to the surface coating on the surface of the base profile.

[0023] To solve the preferably mentioned problem, the invention, in an equally preferred embodiment, further provides that at least one groove is formed in the surface of the base profile between the plugging area and the receiving area, in particular running parallel to these, the base of which has a shadow gap surface made of the second plastic and the opposite walls of which have shadow gap walls made of the second plastic, which is materially bonded, preferably by co-extrusion, to the first plastic of the base profile.

[0024] Such a groove, of which at least one, preferably three, is provided in this preferred embodiment, divides the surface of the base profile into adjacent surface sub-areas, each of which is provided with a surface coating, preferably the same one, so that in the facade cladding profile according to the invention, its visible surface is divided by the at least one shadow gap created at the groove into at least two adjacent visible surface sub-areas. Preferably, all surface sub-areas lie in a common (the same) plane and / or all visible surface sub-areas lie in a common plane.

[0025] It may preferably be provided that all surface areas and thus all coated visible surface areas of a facade cladding profile have the same width, especially when viewed perpendicular to the longitudinal direction and / or extrusion direction.

[0026] Alternatively, it can also be provided that at least two surface areas and thus at least two coated visible surface areas of a facade cladding profile have different widths, especially when viewed perpendicular to the longitudinal direction and / or extrusion direction.

[0027] It can also preferably be provided that all shadow gaps formed on a facade cladding profile, in particular also between two facade cladding profiles, have the same width, especially when viewed perpendicular to the longitudinal direction and / or extrusion direction.

[0028] Alternatively, it may be provided that at least two shadow gaps of all shadow gaps formed on / in a facade cladding profile and / or between two facade cladding profiles have different widths, in particular when viewed perpendicular to the longitudinal direction and / or extrusion direction.

[0029] Preferably, all shadow gap surfaces of a facade joint profile according to the invention lie, at least with their respective central longitudinal axis, and in particular completely, in a common (the same) plane that is parallel to the aforementioned plane of the visible surface / surface areas. It can also be provided that a respective shadow gap surface is inclined at an angle from a position parallel to the surface / visible surface.

[0030] Preferably, in this embodiment, with at least one additional shadow gap, all shadow gap walls of shadow gaps present on the facade cladding profile or formed by joining two facade cladding profiles extend to the height level of the base profile's surface, particularly starting from a shadow gap surface. Both the shadow gaps created by joining and those present in the facade cladding profile thus exhibit a uniform appearance. To an observer, this results in a facade that appears to be composed of a much larger number of facade cladding profiles than is actually the case.

[0031] In a first possible embodiment, the invention preferably provides that the surface coating of the surface, in particular of each surface sub-area, is formed by a film. Such a film can, for example, be bonded to the surface of the base profile, e.g. by means of an adhesive.

[0032] In particular, it is intended that the visible side of the plastic film is designed in a different color than the visible areas of the shadow gap.

[0033] In this foil design, it is particularly preferred that the foil rests on the upper end region of a respective shadow gap wall, preferably is bonded to it in a material-bonded manner, in particular rests on an upper end region of the respective shadow gap wall that extends parallel to the surface of the base profile, in particular extending beyond the thickness of the shadow gap wall.

[0034] Each shadow gap wall made of the second plastic material preferably has, in cross-section perpendicular to the longitudinal direction of the facade cladding profile, a leg that extends parallel to the groove wall in the base profile and has an upper leg at its top end that bends away from this direction and lies parallel to the surface of the base profile and / or the foil plane. This upper leg simultaneously forms a collar or flange area on both sides of the shadow gap opening.

[0035] The aforementioned sloping wall areas of the base profile are also understood here as groove walls in the base profile, although these do not define a groove originally present in the facade cladding profile, but only a groove created by joining together.

[0036] The thickness of the shadow gap wall is preferably considered in an area where the first leg is parallel to the groove wall.

[0037] Preferably, the upper leg extends parallel to the surface of the base profile and / or the foil plane by at least 50% of the thickness of the shadow gap wall, more preferably by at least 75% of the thickness, and even more preferably by at least 100% of the thickness beyond this, but in particular by no more than 200% beyond it.

[0038] In particular, the shadow gap wall on the side of the facade cladding profile with the receiving area can be designed to also have a (lower) leg at its lower end, which is bent towards the receiving groove of the receiving area. The shadow gap wall formed at the receiving area thus encompasses a profile section of the base profile with its upper and lower legs. This lower leg preferably does not run parallel to the surface of the base profile or the foil plane.

[0039] Such a lower leg can preferably also be provided in the embodiments mentioned below, in particular in all possible embodiments of the invention.

[0040] In another second preferred embodiment, the surface coating is made of the second plastic or of a third plastic, which is bonded to the first plastic of the base profile, preferably by coextrusion.

[0041] In this embodiment, in the first alternative, the shadow gap surface, the shadow gap walls, and the surface coating are formed in one piece from the second plastic, which is bonded to the first plastic of the base profile by a material bond, preferably by co-extrusion. Preferably, the base profile is thus completely coated with the second plastic on the visible side, i.e., in the surface coating and the shadow gaps, by a material bond, particularly by co-extrusion, preferably except in an area of ​​the connection area that lies laterally outside the shadow gap surface of the connection area.

[0042] An optical separation between the shadow gap and the visible surface is thus achieved at least by the shaded position of the shadow gap below the surface level of the visible surface.

[0043] By using a third plastic for the surface coating instead of the second plastic from which the shadow gaps are formed, an optically different appearance of the surface coating compared to the shadow gap can be created, even if both are produced by co-extrusion.

[0044] The third plastic may preferably differ from the second plastic only in that it has a different color pigmentation than the second plastic, but in particular, the plastic matrix material into which the color pigments are mixed is otherwise the same. However, the third plastic may also be chemically different from the second plastic, thus differing not only in color pigmentation but also in the plastic matrix material.

[0045] When using a third plastic in the surface coating, it is further preferably provided that this third plastic is also bonded to the second plastic, which forms the shadow gap wall, in the transition area from the surface coating to a respective shadow gap wall, in a materially bonded manner, in particular by co-extrusion.

[0046] A second and a third plastic are preferably extruded through separate co-extrusion dies.

[0047] Even if the surface coating, as with the shadow gap surfaces and shadow gap walls, is made of the second plastic, it is preferably provided that the surface coating is produced with a different coextrusion die than the shadow gap wall and shadow gap surface of a shadow gap, the latter two preferably being produced from the same coextrusion die.

[0048] It may be intended that a separate coextrusion die is used for each shadow gap, or partial shadow gap in the case of shadow gaps that only result from assembly, and for each surface coating, especially for each surface area. This also makes it possible to operate different coextrusion dies with different plastics.

[0049] It is also preferred that the second plastic or the third plastic has a different structure in the area of ​​the surface coating than in the area of ​​the shadow gap walls and / or shadow gap surfaces.

[0050] Visual differentiation can also be achieved through different types of structuring. Preferably, the second or third plastic is structured in the area of ​​the surface coating, e.g., brushed, embossed, or printed, and the second plastic in the area of ​​the shadow gap walls and / or shadow gap surfaces is left unprocessed after extrusion, in particular without further treatment.

[0051] Brushing and / or embossing and / or printing in the area of ​​the visible surface or the surface coating can create high and low areas that have different optical appearances, e.g. because in the low areas there is a material thinning of the second or third plastic above the first plastic of the base profile, especially possibly also so that the first plastic shows through the second or third plastic.

[0052] In general, it may be provided that the second plastic is designed in a different color than the surface coating, especially if the latter is designed as a film, and / or than the first plastic and / or than the third plastic.

[0053] In all versions, it is preferably provided that the first and second plastic and / or the first and third plastic are arranged adjacent to each other without steps and / or edges.

[0054] Preferably, it is generally provided that the layer of the second plastic on the shadow gap surfaces and / or shadow gap walls, in particular also the layer of the second or third plastic in the area of ​​the surface coating, has a thickness (d) of at least 400 micrometers which, with a predetermined color pigment admixture in the second or third plastic, in particular a light color pigment admixture, ensures complete color coverage of the material / the first plastic of the base profile, in particular the wall thickness (d) being greater than 400 micrometers.

[0055] In all possible embodiments, it is preferably provided that each shadow gap has a shadow gap surface with a width b, which is less than or equal to the width a of the shadow gap opening, in particular the shadow gap opening at the height of the surface of the base body or at the height of the surface coating. This results in a design in which the shadow gap widens outwards, which facilitates the incidence of light on the shadow gap walls, preferably those which in this embodiment are not perpendicular to the shadow gap surface.

[0056] The aforementioned width is preferably considered here in the direction of the spacing between the insertion area and the receiving area, in particular perpendicular to the longitudinal extension direction or extrusion direction of the facade cladding profile.

[0057] It is also preferred that the opposing shadow gap walls of a respective shadow gap present in the facade cladding profile or of a shadow gap formed by connecting two facade cladding profiles are not arranged in a mirror-symmetrical manner around a plane perpendicular to the shadow gap surface and parallel to the longitudinal direction of the facade cladding profile.

[0058] Particularly preferred is the arrangement of the two shadow gap walls opposite each other at different angles to the surface coating. For this purpose, the angles formed by the respective shadow gap wall extending beyond the surface coating can be considered. This angle is preferably larger for the shadow gap wall facing the insertion area, especially the one that is on top after the installation of facade cladding profiles, than for the shadow gap wall facing the receiving area, especially the one that is on the bottom after the installation of facade cladding profiles.

[0059] In all possible embodiments, it is further preferred that the second plastic, in the area of ​​a shadow gap, where it transitions from the shadow gap surface to the shadow gap wall, has a smaller radius of curvature (outer radius) between the shadow gap surface and the shadow gap wall in the contact area with the first plastic than the radius of curvature (inner radius) in the free interior of the shadow gap. This, or other, particularly non-radial, configurations, preferably allow for an accumulation of the second plastic material in the free interior at the aforementioned transition area.

[0060] In all possible embodiments, the second or third plastic is preferably formed from a flowable plastic raw material containing color pigments. In a preferred, limiting example, the color pigments constitute 2% to 2.5% of the mass of the plastic raw material.

[0061] Instead of the first and second or third plastic being different colors, it is also possible for the two plastic materials of the first and second or third plastic to be different, apart from the color pigment. This means that chemically different plastics can also be used.

[0062] The shadow gap surfaces and / or shadow gap walls and / or surface coatings, preferably produced by co-extrusion, are preferably extruded onto the base profile and are thus materially bonded to it, and preferably also to each other.

[0063] Advantageously, the base profile, in particular made from recycled rigid PVC, especially conventionally in grey color, has a wall thickness that is higher, preferably many times higher, than the wall thickness of the areas produced by co-extrusion.

[0064] Since expensive color pigments are preferably added to the co-extruded second or third plastic during co-extrusion, the wall thickness of the second or third plastic is preferably not made thicker than necessary for cost reasons.

[0065] Preferably, for an attractive appearance in the assembled facade, the second and / or third plastic layer should completely cover the first plastic layer of the base profile. Particularly in the case of light-colored shadow gaps, the base profile, onto which the second and / or third plastic layer is extruded, must not show through the second and / or third plastic layer.

[0066] In practice, a thickness of at least 400 µm = 0.4 mm has proven suitable for full opacity of the second and / or third plastic layer.

[0067] The second and / or third plastic preferably has a constant wall thickness in cross-section.

[0068] The invention is explained in more detail below with reference to the drawings.

[0069] The figures show, in detail: Fig. 1: the prior art. Fig. 2: a facade cladding profile of a first embodiment according to the invention with a foiled surface and co-extruded shadow gaps shown in cross-section. Fig. 2A-C: detailed views of the first embodiment of Figure 2 Fig. 3: A second embodiment of a facade cladding profile according to the invention with co-extruded shadow gap and co-extruded surface coating shown in cross-section. Fig. 3A-C: Detail views of the second embodiment made of the first and second plastics. Fig. 4A-C: Detail views of the second embodiment made of the first, second and third plastics. Fig. 5: Preferred embodiments of the shadow gap.

[0070] The Figure 1First, it shows the prior art originating from the applicant herself, with some essential features that the invention also exhibits.

[0071] Here, a cross-section of a facade profile 1 with hollow chambers is shown, running lengthwise along the longitudinal direction, which also corresponds to the extrusion direction. It comprises a base profile 2, extruded, for example, from PVC, which here has a surface 2a on its upper side, corresponding to the visible side when properly installed. This surface is covered with a film as a surface coating 3 to determine the visual appearance.

[0072] On the side shown here on the right, the base profile has a plug-in area 4, with which the facade cladding profile 1 can be plugged into a receiving area of ​​another facade cladding profile, which can be seen on the left of this facade cladding profile 1 shown here as receiving area 5.

[0073] The insertion area 4 is lower in height compared to the surface 2a of the base profile or the surface coating 3. It comprises a shadow gap surface 5, which adjoins a sloping wall section 2b of the base profile laterally adjacent to surface 2a. The shadow gap surface is lower in height, specifically parallel to surface 2a, and is formed by a second plastic material, which is bonded to the first plastic material, from which the base profile 2 is formed, for example, by co-extrusion. This second plastic material has a different visual appearance than the first plastic material and / or the foil surface coating 3, for example, because the second plastic material of the shadow gap surface is colored differently, for example, with pigments added to the plastic.

[0074] Extending outwards, and further reduced in height, the plug-in area 4 has a fastening area 4a, which may, for example, have holes / bores or other recesses to fasten the facade cladding profile 1 to a substructure (not shown). Further outwards, the plug-in area 4 has a spring element 4b, which is designed to be inserted into the groove 5a of the receiving area 5 (of another adjacent facade cladding profile, not shown here).

[0075] The receiving area 5 lies within the facade cladding profile 1 below the surface of the base profile 2 and is therefore not visible from the view side. On the left side, the facade cladding profile 1 has a wall section 2c that slopes down from the surface 2a of the base profile 2b towards the receiving area 5. Receiving area 5 contains a receiving groove 5a for receiving a groove element 4b of an adjacent facade cladding profile.

[0076] The foil, which here forms the surface coating 3, is attached to surface 2a and also to the wall areas 2b and 2c sloping downwards from surface 2a. In the prior art, a shadow gap formed between two facade cladding profiles is thus distinguished from the foil solely by the color of the shadow gap surface 5. Such a shadow gap is therefore barely noticeable.

[0077] All of the aforementioned features, with the exception of the film used as a surface coating and its specific course, are also provided for in the invention.

[0078] In a first possible embodiment of the invention, a film can also be used as a surface coating, but in the invention this only covers the surface 2a, not the sloping wall areas 2b and 2c.

[0079] Such an embodiment according to the invention is described in the Figure 2 and in detail in the Figures 2A to 2C depicted.

[0080] As an essential feature of the invention and in contrast to the prior art, the base profile 2 has on its right side a wall section 2b sloping down from its surface 2a to the insertion area 4, on which a shadow gap wall 7 made of the second plastic is formed, which is bonded to the first plastic of the base profile 2 by a material bond, preferably by co-extrusion, wherein this shadow gap wall 7 is formed integrally with the shadow gap surface 6 of the insertion area 4, wherein the base profile 2 further has on its other left side a wall section 2c sloping down from its surface 2a to the receiving area 5, on which a shadow gap wall 7 made of the second plastic is formed, which is bonded to the first plastic of the base profile 2 by a material bond, preferably by co-extrusion. Each shadow gap wall 7 extends at least to the height level of the surface 2a of the base profile 2.

[0081] By joining two facade cladding profiles 1 of this type according to the invention, a more visually pronounced shadow gap is obtained compared to the prior art, because in the invention the shadow gap walls 7 are also formed from the same second plastic. This already results in a visually greater width of the shadow gap thus formed.

[0082] The Figure 2This illustrates a particularly preferred embodiment in which at least one further groove 8, here three further grooves 8, are provided in the surface 2a of the base profile, a shadow gap surface 6 made of the second plastic is formed at the base of each groove, and shadow gap walls 7 made of the second plastic are formed on the opposite groove walls. The second plastic is bonded to the first plastic of the base profile 2 in a material-bonded manner, preferably by co-extrusion. These additional grooves 8 shown can be provided in any number, but do not have to be.

[0083] The Figure 2AFigure 1 visualizes a detail of the first embodiment. It can be seen that the shadow gap wall 7 is bonded to the sloping wall section 2c of the base profile 2 near the receiving area 5, e.g., by co-extrusion. Preferably, the shadow gap wall 7 has a lower leg 7a at its lower end, which extends towards the receiving groove 5a on the underside of the base profile 2.

[0084] Furthermore, the shadow gap wall 7 preferably has a leg 7b at its upper end which extends parallel to the surface 2a, in particular whose surface is flush with the surface 2a. This applies in this embodiment to all shadow gap walls 7 of all shadow gaps of the facade cladding profile 1, regardless of whether the shadow gaps are initially present in the facade cladding profile 1 or are formed by joining two profiles 1 together.

[0085] This creates an upper mounting surface 7 that is larger than the rest of the wall thickness, allowing the foil to be attached as a surface coating 3, e.g., by bonding. The foil can thus be laid on the same plane, without any height difference, on the surface 2a and the shadow gap wall 7.

[0086] The Figure 2BFigure 1 shows the detail of the formation of an additional shadow gap at a groove 8 in the surface 2a of the base profile 2. It can be seen that the entire inner surface of the externally visible shadow gap is formed from the same second plastic. Shadow gap walls 7 and the shadow gap surface 6 are formed in one piece from the second plastic and are bonded to the first plastic of the base profile 2, for example, by co-extrusion. Here, too, the legs 7b, on which the foil rests and is attached, can be seen at the upper end of both shadow gap walls 7. These legs 7b extend parallel to and flush with the surface 2a of the base profile 2. This design according to Figure 2B is provided if the surface 2a is interrupted by at least one groove 8, but can otherwise be omitted.

[0087] The Figure 2CThe detail at the connection area 4 is shown. Here it can be seen that the wall area 2b, which slopes downwards from surface 2a towards connection area 4 or shadow gap surface 6, is formed with a shadow gap wall 7 made of the second plastic, which is bonded to the first plastic of the base profile, for example, by co-extrusion. Here too, the leg 7b, on which the foil rests and is attached, can be seen at the upper end of the shadow gap wall 7. This leg 7b extends parallel to and flush with the surface 2a of the base profile 2.

[0088] All such legs 7b, as e.g. in the Figures 2A , 2B and 2C They extend from the respective shadow gap wall 7 and the shadow gap towards the adjacent surface 2a.

[0089] In the Figure 2CIt is further evident that the shadow gap surface 6, or rather the second plastic component forming it, slopes down further towards the fastening area. This ensures that when inserted into a receiving area 5, its underside can run up onto this sloped area.

[0090] During the execution of the Figures 2 The surface coating 3 is formed by a film that rests on and terminates at the shadow gaps on the upper legs 7b of the shadow gap walls 7. Thus, unlike in the prior art, the shadow gap wall 7 is not coated by the film in the areas facing into the interior of the shadow gap.

[0091] The Figure 3 shows a first alternative of a second version and the Figures 3A-C The details are shown in the same places as before. Figures 2A to 2C The second plastic is shown here as a thick black line throughout.

[0092] In contrast to the first version, this version provides that both the surface coating 3 and the shadow gap walls 7 and the shadow gap surface 6 of each individual shadow gap are formed in one piece from this second plastic, which is bonded to the first plastic of the base profile 1, e.g., by co-extrusion. The appearance on the visible side is thus consistently defined by the second plastic.

[0093] Here, it may be preferable for the second plastic to be mechanically structured in the area of ​​surface coating 3, e.g., by brushing or embossing after co-extrusion. On the side of the receiving area, which is in Figure 3A As can be seen, the shadow gap wall 7 has the lower leg 7b.

[0094] Although the surface areas 3 and the shadow gap walls 7 as well as the shadow gap surfaces 6 are all formed by the same second plastic, it may preferably be provided that the coextruded areas of the surface coating 3 and the coextruded areas 6, 7 of the shadow gap are produced by different coextrusion dies, in particular wherein the melt of the second plastic bonds materially in these different areas.

[0095] When the surface coating is formed in several surface sub-areas separated by groove 8, these can also be created by different extrusion dies.

[0096] It is also possible to provide for the formation of the surface coating and the shadow gaps with the second plastic using only a single co-extrusion die.

[0097] The Figures 4A to 4Cvisualize in the same level of detail as the Figures 3A to 3C another alternative of the second version.

[0098] Here it is provided that the surface coating 3 is formed from a third plastic, which is materially bonded, e.g. by co-extrusion, to the first plastic of the base profile 2 and which is also materially bonded, e.g. by co-extrusion, to the second plastic of the shadow gap, in particular at the top of the upper area of ​​the shadow gap wall 7.

[0099] Due to the simultaneous production of the surface coating 3 and the shadow gap wall 7 during co-extrusion, the previously described formation of an upper leg 7b on the shadow gap wall 7 can be omitted here, because the melts of the third and second plastics bond directly during co-extrusion. The Figures 4A to 4CThe visible separation lines between the surface coating 3 and the shadow gap wall 7 at its upper end visualize the separation between the third and second plastics, with a simultaneous material-bonded connection between these plastics.

[0100] In the explanations of the Figures 4A to 4C Preferably, the third plastic for the surface coating 3 and the second plastic for the shadow gaps 6,7 are co-extruded onto the base profile 2, which originates from another co-extrusion die, through different co-extrusion dies.

[0101] The third plastic differs from the second, for example, by a different color pigmentation with the same plastic matrix, or by a chemically different plastic, especially one that is color pigmented.

[0102] In this embodiment as well, it may be preferable for the third plastic in the area of ​​surface coating 3 to be mechanically structured, e.g. by brushing or embossing after co-extrusion. On the side of the receiving area, which is in Figure 4A As can be seen, the shadow gap wall 7 has the aforementioned lower leg 7b.

[0103] If the third and second plastics were identical, the design would be as follows: Figures 3 .

[0104] The Figure 5 visualizes further details of the respective shadow gap that may be preferably provided, regardless of whether it is created by joining together or is originally present in profile 1 and regardless of whether the surface coating 3 is designed as a film or as a co-extruded layer of the second plastic.

[0105] Here it can be seen that each shadow gap has a shadow gap surface 6 with a width b, which is less than or equal to the width a of the shadow gap opening, in particular the shadow gap opening at the height of the surface 2a of the base body 2 or at the height of the surface coating 3. This results in a shadow gap that widens outwards.

[0106] Furthermore, preferably independently of or in combination with the aforementioned embodiment, it can be provided that the opposing shadow gap walls 7 of a respective shadow gap present in the facade cladding profile or of a shadow gap formed by joining two facade cladding profiles 1 are not arranged symmetrically about a plane perpendicular to the shadow gap surface and parallel to the longitudinal direction of the facade cladding profile. This results in the angles α and β shown here, which the surface coating 3 forms with the shadow gap wall 7 extended beyond it, being unequal. Preferably, the angle α, which points towards the insertion area 4, is larger than the angle β. Reference symbol list
