Description

[0001] The present invention relates generally to a modular structure of a mixtilinear shape, for realizing walls, panels or components for booths and exhibition spaces, display of advertising, communication and furnishing screens.

[0002] The modular structure in question comprises a frame of substantially rigid material, comprising straight and curved elements or components, and one or more laminates or sheets of textile material connected to said frame.

[0003] More particularly, the invention relates to a frame made of at least one substantially flat lower support, intended to rest on the ground or on a stationary surface, and at least one upper support substantially identical and parallel to the lower support, the two supports being mutually spaced apart and rigidly coupled by means of one or more vertical uprights.

[0004] Both supports comprise modular profiles that can have a linear or curved shape and have mounting housings with the vertical uprights, which are made of extruded aluminium, and housings for housing LED lights.

[0005] Vertical uprights can also be connected with horizontal uprights.

[0006] In addition, one or more sheets or laminates (in front of and / or behind the rigid frame) are attached to the lower and upper supports, so that the frame is completely covered.

[0007] The sheets are tensioned to create a flat, homogenous surface and can be printed; thanks to the LED lights inside the frame, they become high-impact displays.

[0008] New and inventive are both the shape of the profiles that make up the lower and upper support and the system that allows the vertical tensioning of the sheets to be adjusted.

[0009] The profiles comprise rigid horizontal elements made of plastic or composite material by means of 5-axis numerically controlled machines, which simplifies production and quality output.

[0010] Inside these profiles there is a 65° lateral recess for the housing of a plastic / silicone or recycled plastic grommet or 'keder', which clamps the sheets covering the frame, allowing very effective anchorage, especially in the curved areas of the supports; in addition, a threaded block is inserted on the vertical uprights, which, by activating a customised bolt, acts on the extension of the vertical dimension.

[0011] Thus, with a reduced dimension of the uprights, an easy coupling of the sheets is possible; furthermore, by unscrewing the bolts connected to the upright block, it is possible to spread the horizontal profiles further apart until an optimal tensioning of the sheets is achieved, in order to obviate defective undulations of the sheets. The aim of the present invention is to solve the typical problems of solutions, such as those mentioned in document IT102020000032939, where the housing of the sheets is formed with a 90° lateral recess which results in the possibility of the sheets becoming disengaged in curved areas.

[0012] Another aim of the present invention is to realise modular profiles with an end side in a circular form, which, combined with a vertical closing element of the frame, itself circular and not flat, makes it possible to create a more harmonious form of the entire modular structure, where it is also possible to accommodate other LED lights.

[0013] Another aim is to be able to create modular structures of various shapes according to customer requirements.

[0014] These and other aims, which will appear more clearly in the following discussion, are achieved by a modular structure with a mixtilinear shape, to realise walls, panels or components for stands and trade fair premises, advertising displays, communication and furnishing screens with new straight and curved modular profiles to compose the lower and upper supports of the rigid frame to which one or more cover sheets are associated, according to claim 1 attached.

[0015] Further detailed technical specifications are contained in the following dependent claims.

[0016] Other features and advantages of the invention will be more apparent from the description of one or more preferred and exemplary, but not limiting, embodiments and the accompanying drawing sheets, wherein: figure 1 represents a perspective view of the modular structure of mixtilinear shape in one possible embodiment, in its complete construction form, according to the invention; figure 2 represents a perspective view of the inner frame of the modular structure of mixtilinear shape in another possible embodiment, comprising lower and upper supports made from the straight and curved modular profiles, connected to the vertical uprights and with further horizontal uprights, also comprising LEDs, according to the invention; figure 3 represents a front view of a section of the modular structure, in this case with straight modular profiles, and exploded views of the shape of the same profiles composing the lower and upper supports, according to the invention; figure 4 represents a front view of the rigid frame formed by the modular profiles of the lower and upper supports fixed to the vertical uprights and the components of the fixing and height adjustment system of the same modular profiles, which are fixed to the vertical uprights, and an exploded view of the lateral areas of said profiles wherein the 65° groove for housing the sheet is obtained, according to the invention; figure 5 represents a front view of the inner side of the different types of straight or curved shapes of said modular profiles, according to the invention; figure 6 represents a front view of the outer part of the different types of straight or curved shapes of the modular profiles, according to the invention.

[0017] With reference to the attached figures, the modular structure (1) of a mixtilinear shape is realized with two supports, an upper and a lower one, comprising modular profiles, connected together by means of barrel couplers (12); some modular profiles have a curved geometry (10) and have an outer part (10A` - 10B') and an inner part (10A" - 10B"), while other modular profiles are realised in a rectilinear geometry (11) and also have an outer part (11') and an inner part (11").

[0018] In addition, profiles (10, 11), made of plastic or composite material, can have shaped ends (9), which themselves have an outer part (9") and an inner part (9').

[0019] On the inner parts (10A", 10B", 11") of the modular profiles housing (30) are made for LED lights and for the attachment of vertical uprights (15A, 15C), which are made of extruded aluminium, while other horizontal uprights (15B), of the same material, can be used to connect the vertical uprights.

[0020] The end modular profiles and any shaped ends (9) of the upper and lower supports of the modular structure (1) have, laterally and at the front and rear parts of the structure, one or more recessed seat (14), preferably arranged at 65° with respect to the vertical uprights (15A, 15C) and realised by CNC machining, in order to be able to insert a sheet and / or a laminate (25), stabilising them by means of a rubber grommet (26).

[0021] The recessed seat (14) is designed to ensure optimum anchorage of the grommet (26) and can have a variable angle to the sheet (25) between 60° and 80°, depending on the specific requirements and the desired curvature.

[0022] The modular structure (1) is then closed at the two sides by the aforementioned sheets or laminates (25), while at the two end portions a flat terminal (20), placed in correspondence with a straight modular profile (11), or a double groove end-piece (arranged at 90° to the sheet or laminate (25)), placed in correspondence with a curved end profile (9) and near the vertical end of the sheet (25), can be fixed. The fastening system of the vertical uprights (15A, 15C) to the modular profiles (9, 10, 11) of the lower support envisages the use of a coupling seat on the profile of the vertical upright (15A, 15C) where at least a first bolt (40) with washers (41) acts on a threaded insert (45), which is locked inside the upright by means of a screw + fastening system (50).

[0023] Analogously, for the fastening system between the vertical upright (15A, 15C) and the upper support, at least a second bolt (40) with washer (41), operating on a threaded insert (46), holds the upper modular profile, by means of a siger (44); thus, loosening the second bolt (40) causes the upper modular profile to move away from the vertical upright (15A, 15C), achieving the tensioning of the fabric of the sheet (25) to the optimum result.

[0024] If the frame is suspended, the second bolt (40) can be replaced by an eyebolt for hanging.

[0025] The assembly methods of the modular structure provide for: 1) the assembly of the horizontal modular profiles (9, 10, 11), upper and lower, by means of barrel couplers (12); 2) the cabling of the LED lighting system in the predetermined housings (30); 3) the assembly of the vertical uprights (15A, 15C) with various screws and any horizontal intermediate uprights (15B), which are used to increase structural rigidity 4) the fixing in the released position between the modular profiles (9, 10, 11) and the vertical uprights (15A, 15C) to facilitate the attachment of the sheets or laminates (25); 5) the hooking of the sheets or laminates (25) (positioned at the front and / or rear of the frame) to the modular profiles (9, 10, 11) of the structure, by means of the insertion of the perimeter grommet (26), which, in the case of the use of sheet (25), are sewn to the fabric of the sheet (25) at the recessed seat (14) specially created in the modular profiles (9, 10, 11); 6) the driving of the bolts (40) located in the upper profiles (9, 10, 11), in order to obtain an optimal elongation in height of the modular structure and, consequently, an optimal tensioning of the fabric (in the case of the use of sheet (25)).

[0026] The invention thus conceived and illustrated herein is susceptible to numerous modifications and variations, all within the scope of the inventive concept as defined by the attached claims.

[0027] Furthermore, all details may be replaced by other technically equivalent elements. Finally, the components used, provided they are compatible with the specific use, as well as the dimensions, may be any according to the requirements and state of the art.

[0028] Where features and techniques mentioned in any of the claims are followed by reference marks, such reference marks have been included for the sole purpose of increasing the intelligibility of the claims and, consequently, have no limiting effect on the interpretation of each element identified, by way of example, by the same.
