Abstract
Description
Technical Field
[0001] This utility model patent application relates to an improved multi-layer element.
[0002] Specifically, the related field is that of multi-layer elements that are used as fabrics or membranes in roofs, coverings, tensile structures, and / or tents and that must meet structural and aesthetic requirements. Background Art
[0003] The applicant of this patent application has worked in this field for many years, continuously developing new structures suitable for use as fabrics or membranes. Through this innovation, the applicant's goal is to increase the artistic freedom of designers who design fabrics, membranes, or similar structures, because these products are currently obtained using a technology that has a negative impact on the aesthetic characteristics of the products in terms of the required strength and elasticity.
[0004] More specifically, the artifacts of the prior art include multiple intertwined yarns that form a mesh grid (which can be defined as a fabric reinforcement) that extends across the entire surface of the artifact. Not only the aesthetics of the finished product, but also the structural characteristics of the product depend on the number of yarns used, the trajectory of the yarn arrangement, the thickness, and the number of yarn crossing points.
[0005] Such yarns include filaments impregnated with resin, whose function is to join the overlapping portions of the yarns. The resin overheats and activates during the manufacturing process. Once the product is made, the resin hardens, thus stabilizing the arrangement of each yarn and the adhesion between the yarns at the points where they overlap each other.
[0006] Therefore, in order to obtain such a product, it is necessary to create a design with a sufficient number of yarns and a sufficient number of contact points between the yarns in order to define a large number of high-strength points. Summary of the Utility Model
[0007] Based on a careful observation of the latter aspect, the inventors have strived to find a solution to manufacture the product without having to consider the structural effects experienced by the current aesthetic choices based on the yarn arrangement.
[0008] More specifically, the inventors' aim is to manufacture such a product in which one or more yarns do not overlap each other, or in which one or more yarns overlap each other at such a small number of points that using current technology to manufacture them cannot ensure the necessary stability and resistance of the product.
[0009] In other words, the aim of this utility model is to overcome the above-mentioned drawbacks by designing a new multi-layer element in which one or more yarns can extend along any type of trajectory without affecting the structural characteristics of the multi-layer element.
[0010] In addition, the object of the present utility model is to design a waterproof multi-layer structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] With reference to the accompanying drawings, a multi-layer element according to the present utility model is described, which is generally designated by the reference numeral 100.
[0021] The multi-layer element 100 includes a first layer A, which includes at least one yarn 1; 101; 102; 103; 1a, 1b, 1c, 1d, and the yarn includes portions arranged side by side and / or intertwined. It should be noted that in this patent application, the term "interwined" means that the yarns or portions of the yarns are superimposed on each other and thus in contact with each other at a point.
[0022] The at least one yarn 1; 101; 102; 103; 1a, 1b, 1c, 1d is a composite yarn, which includes at least one elongated filament 10 impregnated with a polymer or natural resin 11. Specifically, as Figure 7 shown, the at least one yarn 1; 101; 102; 103; 1a, 1b, 1c, 1d includes a plurality of filaments (10) arranged side by side and is attached by the resin 11 used to impregnate them.
[0023] The filaments 10 are made of carbon and / or meta-aramid and / or para-aramid and / or meta-aramid polyamide and / or PBO and / or polypropylene and / or polyester and / or ceramic and / or high-modulus polyester and / or basalt and / or Vectran and / or Spectra and / or bamboo and / or hemp and / or of organic or plant type. In fact, the yarns are of synthetic or natural origin. The materials listed above are for illustrative purposes only, and the filaments 10 can also be made of other materials.
[0024] In addition, the multi-layer element 100 includes a second layer B, which includes a film 2, and the yarns 1; 101; 102; 103; 1a, 1b, 1c, 1d of the first layer A are arranged and attached to the film 2, which serves as a support for the yarns 1; 101; 102; 103; 1a, 1b, 1c, 1d. The film 2 is made of a material capable of melting with the resin 11 of the yarns 1; 101; 102; 103; 1a, 1b, 1c, 1d.
[0025] Specifically, the film 2 of the second layer B is made of the same material as the resin 11 of the filaments 10 used to impregnate each yarn 1; 101; 102; 103; 1a, 1b, 1c, 1d.
[0026] Since the film 2 and the resin 11 are made of the same material, delamination of the multi-layer element 100 (i.e., separation of the yarns from the film) can be prevented, which often occurs when different materials are attached and when the multi-layer element is subjected to high stress or impact.
[0027] In fact, the resin 11 and the film 2 made of the same material form an unbreakable attachment between the yarn and the film. Or rather, the resin 11 and the film 2 melt to produce a homogeneous structure.
[0028] The film 2 and the resin 11 are made of waterproof materials.
[0029] The resin 11 and the film 2 are composed of the following components:
[0030] - Polyester and polyether-based polyurethane resins; or
[0031] - Epoxy resins; or
[0032] - Urethane resins; or
[0033] - Caprolactone resins; or
[0034] - Polyolefin resins; or
[0035] - Fluoropolymer plastics.
[0036] The materials listed above are for illustrative purposes only, and the film 2 and thus the resin 11 can be made of other materials similar to those listed above.
[0037] In a preferred embodiment of the present innovation, the film 2 is semi-transparent or transparent in order to distinguish the filaments 10 of the yarn from the film 2. This feature has aesthetic advantages because if the trajectory followed by the yarn can form a particularly eye-catching design or shape, then due to the semi-transparency or transparency of the film 2, even if the yarn is located behind the film 2, the observer can appreciate this art form.
[0038] For the sake of illustration, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 5A 、 Figure 6 and Figure 6A show different types of multi-layer elements 100, which differ in the number of yarns 1; 101; 102; 103; 1a, 1b, 1c, 1d in the first layer A and / or the trajectory followed by the said yarns 1; 101; 102; 103; 1a, 1b, 1c, 1d in the first layer A.
[0039] For example, Figure 1 shows a multi-layer element 100 in which the first layer A includes a single yarn 1, and the single yarn 1 has portions that are intertwined (superposed on each other), thus defining a junction point 30. In addition, the yarn 1 has a free trajectory that includes a curved portion 4 extending along a circular arc greater than 90° and an inclined continuous portion that defines a dotted line 5 having an edge.
[0040] Figure 2 Shows a multi-layer element 100, in which the first layer A includes a single yarn 101 extending along a helical trajectory and having no interlaced or overlapping portions.
[0041] Figure 3 Shows a multi-layer element 100, in which the first layer A includes a plurality of yarns 102 that define a plurality of interlaced and overlapping loops, thereby defining a junction point 30.
[0042] Figure 4 Shows a multi-layer element 100, in which the first layer A includes a plurality of yarns 103 arranged side by side, which follow similar curved trajectories and never interlace or overlap.
[0043] Figure 5 , Figure 5A , Figure 6 and Figure 6A Shows two different types of multi-layer elements 100, in which the first layer A of each multi-layer element 100 includes:
[0044] - A first yarn 1a and a second yarn 1b that are interlaced and overlapped in their respective directions; and
[0045] - A third yarn 1c that is interlaced with the first yarn 1a and the second yarn 1b and is arranged above, below, and between the first and second yarns 1a, 1b; the third yarn 1c has an independent direction relative to the directions of the first and second yarns 1a, 1b.
[0046] In addition, the first layer A further has one or more fourth yarns d that are stacked on the first, second, and third yarns 1a, 1b, 1c and have an independent direction relative to the directions of the first, second, and third yarns.
[0047] The first yarn 1a, the second yarn 1b, the third yarn 1c, and the fourth yarn 1d define the junction points 30 of the grid 3 by crossing each other. In other words, the yarns 1a; 1b, 1c, 1d form a grid 3 with excellent structural properties. In addition, the graphic pattern of the grid 3 composed of the first yarn 1a, the second yarn 1b, the third yarn 1c, and the fourth yarn 1d is very eye-catching.
[0048] The directions of the first yarn 1a and the second yarn 1b are inclined to each other, and the inclination angle is between 0° and 90° (excluding the extreme values).
[0049] The directions of the first strand 1a and the third strand 1c are inclined to each other, and the inclination angle is between 0° and 90° (excluding the extreme values).
[0050] The directions of the second yarn 1b and the third yarn 1c are inclined to each other, and the inclination angle is between 0° and 90° (excluding the extreme values).
[0051] The directions of the fourth yarn 1d and the third yarn 1c are inclined to each other, and the inclination angle is between 0° and 90° (excluding the extreme values).
[0052] Advantageously, the mutual arrangement of the first, second, third, and fourth yarns 1a, 1b, 1c, 1d ensures a high technical strength of the grid 3.
[0053] In addition, the yarns 1a, 1b, 1c, 1d define meshes on the grid 3, and the meshes are defined by irregular closed broken lines, that is, having different sides and different angles.
[0054] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , optionally, the yarns 1, 101 or the yarns 102, 103, 1a, 1b, 1c, 1d of the first layer A may not have points in contact with the peripheral edge 20 of the film 2.
[0055] In this case, the yarns 1; 101 or the yarns 102; 103; 1a, 1b, 1c, 1d do not have a structural function but only an aesthetic function.
[0056] The multi-layer element 100 according to the present innovation can be used for roofs.
[0057] For the sake of convenience of description,[[]] Figure 8 a possible application of the multi-layer element 100 according to the present innovation is shown.
[0058] Specifically, in[[[]] Figure 8 the multi-layer element 100 is used as a covering for the tensile structure T.
[0059] Alternatively, the multi-layer element 100 can also be used as a covering for a gazebo or a similar structure.
[0060] Advantageously, the multi-layer element 100 has a dimming effect (because it reduces reverberation) and a sound insulation effect.
[0061] Through the above description, the advantages of the present innovation are now obvious.
[0062] Attaching the film 2 of the second layer B to the yarns of the first layer A allows designers and artists to give full play to their imaginations and arrange the yarns according to the desired trajectories without affecting the structural characteristics of the multi-layer element 100.
[0063] In fact, with such an innovation, designers and artists can arrange the yarns along any trajectory to obtain any type of design.
[0064] In addition, it is worth reiterating that since the resin 11 of the yarn and the film 2 are made of the same material, the two layers A and B can be fused together, thereby reducing the aforementioned risk of delamination.
[0065] Finally, it should be noted that due to the provision of the waterproof film 2, the multi-layer element 100 can also be used as a waterproof covering.
[0066] Those skilled in the art can make various modifications to the current embodiments of the present utility model, and these modifications still fall within the scope of the present utility model as expressed in the appended claims.
