Description

[0001] The invention relates to a system, in particular for hanging a curtain arrangement, wherein the system comprises at least one guide rail, at least one guide element and at least one assembly kit, which at least partially comprise polymeric materials according to the features of claim 1.

[0002] Such systems are described in the prior art and have proven their worth. However, these systems repeatedly suffer from the problem that, during normal use, they can produce operating noises that are perceived as unpleasant.

[0003] Furthermore, such systems are assembled from guide rails of varying dimensions, which can be either linear, elongated guide rails or curved guide rails with a radius. The connection points between the individual guide rails, in particular, lead to additional noise generation, which is also perceived as disturbing.

[0004] For example, DE 1139950 A discloses a curtain track, in particular an internal runner track with rolling or sliding hangers, wherein the contact surfaces between the curtain track and the hanger are provided with inserts made of a solid, lubricable material, such as hard wax or the like.

[0005] The inserts are provided on vertical side surfaces and horizontal sliding or rolling surfaces of the running groove and the lateral boundary surfaces of the guide slot of the running groove.

[0006] A disadvantage of this solution has been found to be that running noises occur at the connection points between the individual guide rails and that the inserts, which consist of, for example, hard wax, lead to contamination of the guide rail or the guide elements.

[0007] Therefore, the present invention aims to overcome the disadvantages of the known prior art and to present a system, in particular for hanging a curtain arrangement, which can be manufactured economically and sustainably, which greatly reduces any running noise along the guide rails, and which enables a smooth and quiet movement that is almost noiseless.

[0008] According to the invention, the problem is solved by the features of claim 1. Further advantageous embodiments are described in the dependent claims.

[0009] It has surprisingly been shown that a system, in particular for suspending a curtain arrangement, comprising at least one guide rail, at least one guide element, and at least one assembly, which at least partially consist of polymeric materials, wherein the assembly comprises at least two sections, wherein the at least two sections are connectable to form a hollow body that at least partially encloses a cavity and constitutes the system for suspending a curtain arrangement, wherein the two sections are essentially flat and flexible and can be moved from a first state (eZ), in which the sections are movable and can be rolled up from a flat or parallel arrangement, to a second state (zZ), in which the sections are arranged at approximately an acute angle to each other and can be transferred into the at least one guide rail in such a way that they can be moved into a third state (dZ), in which the sections are approximately opposite each other,The system, which is arranged to abut at least one inner wall of the guide rail, and in such a way that the sections have at least one flexible element, solves this problem. Advantageously, the system, particularly for hanging a curtain arrangement, is designed to completely bridge existing connection points of the guide rails, so that the slidably arranged guide elements can be moved almost without noise. A further advantage of the system, particularly for hanging a curtain arrangement, is that it can be used without additional lubricants that could potentially contaminate the curtain arrangement.

[0010] The system, particularly for hanging a curtain assembly, is further designed such that the sections of the kit, via at least one flexible element, comprise at least two interconnected subsections. This makes the system, particularly for hanging a curtain assembly, economical and sustainable to manufacture. A further advantage is that the system, particularly for hanging a curtain assembly, can be both newly installed and used for the renovation of existing systems.

[0011] One advantage of the system, particularly for hanging a curtain arrangement, is that the at least two, hingedly connected, sections of the kit are arranged approximately parallel to each other in a second state (zZ). This makes it particularly easy to install the kit in almost any cross-section of existing guide rails.

[0012] A further advantage of the system, particularly for hanging a curtain assembly, is that the at least two, pivotally connected, subsections of the kit are arranged in a third state (dZ) approximately opposite each other, resting against at least one inner wall of the guide rail. It is advantageous here that the kit can be inserted not only into linear but also into curved or radiused guide rails in such a way that the connection points between the individual guide rails are bridged.

[0013] A further advantage of the system, particularly for hanging a curtain assembly, is that a first flexible element and / or a second flexible element of the kit is designed as a wall thickness reducer, a film hinge, or the like. This advantageously results not only in economical and sustainable manufacturing but also in the kit being adaptable to all existing guide rail geometries.

[0014] The system, particularly for hanging a curtain assembly, is further designed such that a third flexible element is formed as a separable element between the sections of the kit, specifically as a predetermined breaking point. This allows the kit to be inserted very quickly, with minimal effort and without tools, into existing guide rails of systems, particularly for hanging a curtain assembly.

[0015] A further advantage of the system, particularly for suspending a curtain assembly, is that the first flexible element and / or the second flexible element of the kit has a thickness of approximately 0.1 to 0.8 mm, preferably 0.2 to 0.6 mm, and most preferably 0.2 to 0.4 mm. This enables economical and sustainable manufacturing.

[0016] Another advantage of the system, particularly for hanging a curtain arrangement, is that the third flexible element of the kit has a thickness of about 0.01 to 0.8 mm, preferably 0.05 to 0.5 mm, and most preferably 0.1 to 0.3 mm.

[0017] This makes the kit easy to install, especially when mounting it in existing guide rails, and allows for assembly with almost no tools required.

[0018] The system, particularly for hanging a curtain arrangement, is advantageously designed so that the sections of the kit are joined together in one piece. This enables very economical and sustainable production.

[0019] The material of the sections of at least one kit 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 acetate (PVAC) is based on thermoplastic polymers based on olefins (TPE), such as thermoplastic polyurethane (TPU), and mixtures of at least two of these materials;

[0020] Furthermore, the system, particularly for suspending a curtain assembly, is advantageously designed such that the material of the at least one assembly contains at least one of the following additives: stabilizers to improve resistance to light, UV radiation, and weathering; stabilizers to improve thermal and thermo-oxidative resistance; stabilizers to improve hydrolytic resistance; stabilizers to improve acidolytic resistance; lubricants; demolding aids; color additives; crystallization-regulating substances and nucleating agents; flame retardants; impact modifiers; fillers; and / or plasticizers. The additives can advantageously comprise renewable raw materials in proportions of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%, as verified by mass balance analysis, e.g., using ISCC.

[0021] Furthermore, the system, particularly for hanging a curtain assembly, is designed such that the sections of the kit have at least one receiving element at at least one free end. Advantageously, this makes it possible to easily insert and position the kit in existing guide rails.

[0022] Another preferred embodiment relates to a system, particularly for suspending a curtain assembly, according to one of the preceding embodiments, wherein the receiving element of the at least one assembly is based on a polymeric material, preferably styrene-ethylene-butadiene-styrene block copolymer (SEBS), thermoplastic olefin-based elastomer (TPO), thermoplastic urethane-based elastomer (TPU), thermoplastic copolyester (TPC), styrene block copolymers (SBS, SEBS, SEPS, SEEPS and MBS), thermoplastic copolyamide (TPA) and the like. The polymeric material can advantageously comprise renewable raw materials from 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%. This measure has the advantage that this material is readily available at low cost, easy to process, and also simple to chemically modify.

[0023] Furthermore, it has proven advantageous in this system, particularly for suspending a curtain assembly, that the material of the at least one receiving element arranged at at least one free end of a section of the assembly has a Shore A hardness of 50 to 99, preferably 55 to 95, and particularly preferably 60 to 90, according to DIN EN ISO 868:2003-10. This advantageously makes it possible to easily insert the assembly into existing guide rails and to arrange it in such a way that it is not longitudinally displaceable within the guide rails when used as intended.

[0024] A further advantage of the system, particularly for hanging a curtain arrangement, is that the at least one receiving element, which is arranged at at least one free end of a section of the kit, is arranged at at least one free end of the guide rail.

[0025] A further advantage of this system, particularly for hanging a curtain assembly, is that the at least one receiving element, located at at least one free end of a section of the kit, is arranged to at least partially encompass at least one free end of the guide rail. This makes it possible not only to insert the kit easily or without tools into existing guide rails, but also ensures that, when used as intended, it is not longitudinally displaceable within existing guide rails.
