Description

[0001] The invention relates to a closure arrangement for covering and closing openings in buildings, roofs, walls, in particular for weather protection, for pergolas, for canopies, for doors, gates and the like, comprising at least one profile arrangement, wherein the profile arrangement has at least one hollow chamber and at least one connecting means, wherein the profile arrangement has at least one structural layer, wherein the at least one structural layer has at least a portion of a polymeric material, wherein the profile arrangement has at least one reinforcing insert, preferably fully embedded in the structural layer, according to the preamble of claim 1; and an opening in buildings, roofs, walls, in particular for weather protection, for pergolas, for canopies, for doors, gates and the like with such a closure arrangement.

[0002] Such locking arrangements are already known in the prior art and have already proven their worth in practice.

[0003] For example, such a closure arrangement, referred to as sun protection, is disclosed in DE102019008027A1.

[0004] This closure arrangement, referred to as a sunshade, comprises a supporting structure with a frame formed from two longitudinal profiles connected by two transverse profiles, a first transverse profile at one end of the sunshade and a second transverse profile at the other end, wherein the frame is equipped on its inside with an inwardly directed and recessed channel, and wherein the sunshade further comprises a number of parallel louvers extending longitudinally (X-X') between the longitudinal profiles and rotatably arranged about an axis of rotation, wherein the louvers, or at least a part thereof, are rotatably connected to one another and these louvers are rotatable between a closed position, wherein the underside of the louvers covers the inner edge of the channel when viewed from above, and an open position.wherein these louvers are inclined upwards from this closed position over a certain opening angle (A) about their axis of rotation, which is located along or at a short distance from a first longitudinal edge which, in the closed position of the louvers, is closest to the first transverse profile, the first transverse profile having on its inside a recess for the first louver which is closest to this first transverse profile and in which this first louver can be rotated away at least over a certain width, up to a maximally open position.

[0005] A disadvantage of this type of closure, known as sun protection, is that high quality variations occur during the manufacture of the individual components, due to the use of different materials, particularly with regard to thermal expansion, shrinkage behavior in both heat and cold, and the significantly different linear coefficients of thermal expansion of the materials of the individual components.

[0006] A further disadvantage of this state of the art is that the costs of manufacturing the individual components are quite high due to the materials used, and that their assembly is very time-consuming and expensive.

[0007] Another disadvantage is that the louvers of this type of closure, designated as sun protection, are particularly prone to malfunction when used as intended. Further disadvantages include the considerable noise pollution generated during precipitation such as rain, hail, and the like, as well as extensive condensation on the surface due to the dew point.

[0008] This is where the invention comes in, which aims to provide a generic closure arrangement for covering and closing openings in buildings, roofs, walls, in particular for weather protection, for pergolas, for canopies, for doors, gates and the like, which is economically and sustainably manufacturable, which has optimized properties when used as intended in both heat and cold conditions, as well as under the influence of moisture, which is visually appealing with optimized material use, and such an opening in buildings, roofs, walls, in particular for weather protection, for doors, gates and the like.

[0009] According to the invention, this problem is solved by the features of claim 1 and claim 10. Further advantageous embodiments are described in the dependent claims.

[0010] It was surprisingly discovered that a closure arrangement for covering and closing openings in buildings, roofs, walls, in particular for weather protection, for pergolas, for canopies, for doors, for gates and the like, comprising at least one profile arrangement, wherein the profile arrangement has at least one hollow chamber and at least one connecting element, wherein the profile arrangement has at least one structural layer, wherein the at least one structural layer has at least a portion of a polymeric material, wherein the profile arrangement has at least one reinforcing insert, preferably fully embedded in the structural layer, is characterized in that the profile arrangement has a flexural stiffness about the x-axis of approximately 17 to 29 x 10⁹ N / mm², preferably approximately 18 to 22 x 10⁹ N / mm² according to DIN EN ISO 178-2019-08, and that the profile arrangement has a linear coefficient of thermal expansion α of approximately 12 to 64 × 10⁻⁶ / K,preferably 16 to 30 × 10⁻⁶ / K according to DIN EN ISO 11359-2:2021-11, that the material of the at least one structural layer comprises microhollow spheres consisting of a plastic shell filled with a gas, fulfills this function. This makes it possible for the first time to provide a closure arrangement for covering and closing openings in buildings, roofs, walls, especially for weather protection, for pergolas, canopies, doors, gates, and the like, which is economically and sustainably manufacturable, which exhibits optimized properties under intended use in both heat and cold conditions, as well as under the influence of moisture, which is visually appealing due to optimized material usage, and for such openings in buildings, roofs, walls, especially for weather protection, for pergolas, canopies, doors, gates, and the like.

[0011] The bending stiffness Sb characterizes the resistance of a component / profile arrangement subjected to bending in a planar cross-section A to curvature about the bending axis, according to the following formula: S b = E * I

[0012] The bending stiffness Sb indicates the magnitude of the bending moment relative to the deflection. For homogeneous cross-sections, it is calculated as the product of the elastic modulus of the profile material and the axial area moment of inertia of the given cross-section of the profile.

[0013] The linear coefficient of thermal expansion is determined using the following formula: α = ΔL / L ⋅ ΔT

[0014] The values ​​were measured at 20°C and in the longitudinal direction of the profile L or in the extrusion direction.

[0015] Here, ΔL denotes the change in length of the length element L and ΔT the temperature change that causes the change in length ΔL.

[0016] The linear coefficient of thermal expansion of the profile arrangement is influenced on the one hand by the polymeric material of the structural layer, which forms the polymeric or thermoplastic base of the profile arrangement, and on the other hand by the material of the reinforcing layer. For example, steel has a coefficient of thermal expansion of αSt ≈ 12 × 10-6 / K, and polymeric materials (depending on the chemical structure of the polymeric material) have a coefficient of αKu ≈ 80 × 10-6 / K.

[0017] If, for example, one wants to achieve a linear coefficient of linear expansion for the profile arrangement as a whole, which corresponds approximately to that of aluminum (α Al = 23.1 · 10 -6< / K ), this structural layer must be designed using the materials plastic as well as metal and / or fiber matrix semi-finished products in such a way that the desired linear coefficient of linear expansion is achieved in the profile arrangement.

[0018] This reduces / avoids the occurrence of mechanical stresses due to different linear coefficients of thermal expansion.

[0019] The closure arrangement is further designed such that the reinforcing insert is band-shaped and made of metal or a fiber matrix semi-finished product with a plastic matrix into which, preferably endless, reinforcing fibers are integrated.

[0020] The reinforcing layer can be in the form of a strip. Strip-shaped means that, in cross-section, the width of the reinforcing element is significantly greater than its thickness, for example, more than twice or more than three times as wide. The reinforcing layer can consist of metal (e.g., steel) or a fiber-matrix semi-finished product with a plastic matrix into which, preferably continuous, reinforcing fibers are integrated. In particular, the fiber-matrix semi-finished product can be in the form of an organosheet. Organosheets are prefabricated semi-finished products, available, for example, as strip material – especially rolled – and consist of a woven or non-woven fabric containing the reinforcing fibers, which is embedded in a thermoplastic matrix.

[0021] Glass, aramid, and / or carbon fibers are preferably used as the reinforcing fibers. Advantageously, all reinforcing fibers run in the extrusion direction.

[0022] The fiber-matrix semi-finished product generally has the advantage that, on the one hand, it significantly increases the mechanical strength of the profile assembly and, on the other hand, also possesses good flexural stiffness and thermal insulation properties. Within the scope of the invention, it is therefore particularly important that at least one strip-shaped fiber-matrix semi-finished product is provided in the structural layer of the profile assembly. In this case, the good thermal insulation of the reinforcing material is of particular importance, as it would otherwise act as a thermal bridge. The reinforcing insert can advantageously have a thickness of approximately 0.1 to 1.2 mm, preferably 0.2 to 0.8 mm. Furthermore, it is within the scope of the invention that the reinforcing insert is perforated, i.e., provided with openings of various geometries.Furthermore, it is within the scope of the invention that the reinforcing insert is coated on at least one surface with at least one primer and / or at least one adhesion promoter.

[0023] Within the scope of the invention, at least one metal reinforcement insert is provided, preferably arranged in the immediate vicinity and parallel to the outer surface of the structural layer of the profile arrangement. The metal reinforcement insert is advantageously also ribbon-shaped and is characterized by the fact that it is generally more cost-effective and possesses higher flexural stiffness compared to the fiber-matrix semi-finished product. Since this reinforcement insert is oriented transversely to the direction of heat flow in the preferably described arrangement, no significant temperature gradient runs along the metal reinforcement, so that the good thermal conductivity of the metal insert does not result in any relevant deterioration of the thermal insulation properties of the entire housing. In such a case, the metal reinforcement insert can therefore be used without adversely affecting the thermal insulation of the housing.

[0024] Within the scope of the invention, it is further provided that the at least one profile arrangement comprises multiple reinforcing inserts. Furthermore, it is within the scope of the invention that at least one profile arrangement is reinforced with both at least one fiber-matrix semi-finished product and at least one metal reinforcing insert. Thus, closure arrangements can be provided that are both economical and sustainable to manufacture and that exhibit optimized mechanical properties compared to profile arrangements from the prior art; in particular, the profile arrangements according to the invention are at least 20% lighter than comparable profile arrangements, for example, made of aluminum.

[0025] The locking mechanism is designed in such a way that the profile arrangement has a thermal conductivity of approximately 0.1 to 0.2 W / mK, preferably of approximately 0.13 to 0.16 W / mK according to DIN 51007-1:2024-08.

[0026] In this advantageous embodiment, the closure arrangement, in particular the profile arrangement, is designed such that it exhibits reduced condensation of, for example, moisture on its surfaces, so that the surfaces of the profile arrangement of the closure arrangement are not contaminated by, in particular, so-called biofilms.

[0027] Furthermore, the closure assembly is designed such that the structural layer of the profile assembly with expanded microspheres has a density of 1.0 g / cm³ to 1.35 g / cm³, preferably 1.10 g / cm³ to 1.25 g / cm³, according to DIN EN ISO 1183-1:2019-09. This makes closure assemblies available that, on the one hand, have a reduced overall weight relative to their length of approximately 2.5 kg / m and, on the other hand, can be manufactured both economically and sustainably.

[0028] Another advantage of the closure arrangement is that the microhollow spheres arranged in the structural layer of the profile arrangement have a diameter of 5 to 60 µm, preferably 10 to 50 µm, in the unexpanded state.

[0029] The closure arrangement is also designed such that the microhollow spheres arranged in the structural layer of the profile arrangement have a diameter of 20 µm to 180 µm, preferably 30 µm to 140 µm, in the expanded state.

[0030] As a result, the profile arrangements of the locking mechanism not only have a reduced weight, but also correspondingly good bending stiffnesses or sufficiently high strength values ​​as well as optimized bending stiffnesses.

[0031] Another advantage of this type of closure is that its intended use for covering and closing openings in buildings, roofs, walls, especially for weather protection, for pergolas, for canopies, for doors, gates and the like, contributes to a significant reduction in noise development or noise pollution in their vicinity, especially during precipitation such as rain, hail and the like.

[0032] Surprisingly, it was found that when the closure arrangement is used as intended, a reduction in noise generation or noise pollution, for example during rain exposure on the upper surfaces of the profile arrangements of the closure arrangement, by about 30% according to DIN EN ISO 140-18:2007-02 is possible.

[0033] It is also advantageous in the closure arrangement that at least one sealing element is arranged on at least one profile arrangement.

[0034] Another advantage of the closure arrangement is that at least one sealing element is arranged on at least one connecting element and / or at least one connecting device of the profile arrangement.

[0035] Furthermore, the closure arrangement is designed such that at least two profile arrangements, arranged side by side in the longitudinal direction L of the profile, are operatively connected to each other via at least one sealing element.

[0036] When used as intended, this sealing element prevents the ingress of moisture, which may accumulate, for example, on the base of the connector and / or the connecting device and would otherwise penetrate unhindered below the connector / connecting device into the spaces below.

[0037] The closure arrangement is further designed such that the at least one sealing element arranged on the at least one connecting means and / or connecting device is arranged in a force-locking and / or form-locking and / or material-locking and / or one-piece manner.

[0038] The material of at least one structural layer of the profile arrangement is based on polyolefin, such as polypropylene (PP) or polyethylene (PE); a styrene-based polymer, such as polystyrene (PS) or styrene-butadiene copolymer with a predominant styrene content (SB) or acrylonitrile-styrene-acrylate copolymers (ASA) or acrylonitrile-butadiene-styrene copolymers (ABS) or styreneacrylonitrile (SAN); polybutylene terephthalate (PBT); polyethylene terephthalate (PET); polyoxymethylene (POM); polyamide (PA); polymethyl methacrylate (PMMA); polyphenylene oxide (PPO); polyetheretherketone (PEEK); polyphenylene sulfide (PPS); liquid crystal polymer (LCP); polyamide-imides (PAI); polyphenylsulfone (PPSU); polyaryletherketone (PAEK); polyacrylonitrile (PAN); polyetherketone (PEK); polyimide (PI); polyisobutene (PIB); polyphthalamide (PPA); polypyrrole (PPY); Polyurethane (PUR); polyvinyl alcohol (PVA);Polyvinyl chloride (PVC), polyvinyl acetate (PVAC), thermoplastic polymers based on olefins (TPE), and mixtures of at least two of these materials.

[0039] The closure arrangement is also designed such that the material of the structural layer of the profile arrangement contains at least one of the following additives: stabilizers to improve resistance to light exposure, UV radiation and weathering; stabilizers to improve thermal and thermo-oxidative resistance; stabilizers to improve hydrolytic resistance; stabilizers to improve acidolytic resistance; antibacterial additives; lubricants; demolding aids; color additives; crystallization-regulating substances and nucleating agents; flame retardants; impact modifiers; fillers and / or plasticizers.
