Description

Technical Field

[0001] This invention relates to a tubular element of cellulose or paper material for making a suspension. The invention also relates to a process for manufacturing the tubular element of cellulose or paper material for making a suspension, and a suspension using the tubular element. Background Technology

[0002] In recent years, a strong ecological trend has emerged in the clothing hanging device industry: abandoning traditional plastic materials in favor of more recyclable and environmentally friendly materials.

[0003] Currently known suspensions are made from cellulose pulp or paper materials, and are appropriately shaped to have the typical shape of traditional shoulder suspensions, mainly for clothing such as coats, jackets, sweaters or shirts.

[0004] The international publication WO2021 / 228693 A1 owned by the applicant of this patent application is an example of this type of suspension, which discloses a suspension made of cellulose pulp, which is shaped in a simple and effective manner through several steps to obtain the shoulder required for storing the aforementioned clothing.

[0005] Clearly, this type of suspension does not require a tubular element to achieve the desired function, as the function of supporting the garment is achieved by the shoulder of the suspension; however, such an element is necessary in suspensions specifically designed for garments such as trousers and skirts, because they do not have a shoulder and have two possible constructions:

[0006] Two parallel elements are connected together by two C-shaped segments to form a groove that allows clothing to be placed across the lower element for storage; the hook of the hanging element is preferably located at the midpoint of the upper element. Figure 16-19 This configuration is shown in the figure, which uses the tubular element of the present invention;

[0007] An element having a hanging hook at its midpoint and clamps at both ends, which are provided with clips that allow clothing to be hung by clamping the clothing. Figure 7 This configuration is shown in the figure, which uses the tubular element of the present invention.

[0008] Currently, tubular elements made of cellulose or paper materials are produced by starting with strips that are spirally wound around themselves, with adhesives used to secure the structure at the bends. However, elements obtained in this way do not yet have a sufficiently large moment of inertia to withstand the typical stresses of a suspension garment. If the forces generated by suspending clothing are applied to a tubular element made in this way, the element will bend excessively, and the bends will often come undone.

[0009] Document US 2025887 A describes (the following figure references are related to this document) a method for manufacturing suspension components ( Figure 1 Tubular elements of cellulose or papery material (page 2, column 1, line 40), having a cylindrical configuration, with a substantially circular cross-section perpendicular to its longitudinal axis. Figure 5 ), flat element ( Figure 5 Component 13) protrudes radially outward from its surface ( Figure 5 The flat element is integral with the tubular element and extends along the entire longitudinal length of the tubular element. Figure 1 , 2 ).

[0010] Document US 2021 / 037999 A1 illustrates (the following figures are associated with this document) a process for making tubular elements of cellulose or paper material for suspension components. Figure 7-8 (b) This process utilizes a series of stations including rollers and / or guides. Figure 7-8 b, elements 9, 10, 11), to make the total (in general) cellulose or paper material a continuous strip ( Figure 7-8 b, element 7) advances, the workstations are arranged along the advancing direction of the strip and operate at different portions on opposite sides, the position and angle of each workstation relative to the strip are appropriately designed to gradually form a cylindrical shape, which is formed by flat elements (b, element 7) formed by the edges of the strips adjacent to each other.

[0011] Additionally, see document KR 200452351 Y1, which illustrates (the following figure references are related to this document) a suspension element ( Figure 5 , 6 ), which has paired elements ( Figure 5 Components 320 and 200), the paired components are parallel to each other and are connected by a pair of components arranged at both ends of the component ( Figure 5 , 6 The components 310 are interconnected, and hooks are arranged on the upper component. Figure 5 , 6 (element 100), the suspension element is adapted to support clothing placed on its lower element.

[0013] The purpose of this invention is to manufacture a tubular element made of cellulose or paper material that can withstand the typical stresses present in suspension components.

[0014] The object of the present invention is achieved by means of a tubular element, which is obtained from a continuous strip and shaped to obtain a cylindrical shape, with a flat element protruding radially outward from the surface of the cylindrical shape.

[0015] Another object of the present invention is to provide a process for obtaining the aforementioned tubular element for suspension, the process comprising using a series of rollers and / or guides appropriately positioned to obtain the desired shape from a continuous strip.

[0016] It should be noted that before carrying out the process involved in this invention, the continuous strip of cellulose or paper material can be moistened first, and then deformed by a roller station and / or guiding device to facilitate subsequent forming.

[0017] Similarly, before deformation via roller stations and / or guide devices, continuous strips of cellulose or paper materials can be heated to temperatures above room temperature, which also facilitates their subsequent molding. Attached Figure Description

[0027] Figure 1 A specific embodiment of the tubular element 1 according to the present invention is shown; in particular, a slit 2001 is provided in the upper central portion of the tubular element 1, and holes 2000 are provided at both ends of the tubular element 1, into which rods 2002 can be inserted, the purpose of which will be described in detail later. In fact, as... Figure 7 As better shown, the garment clamp 3000 can be applied to the tubular element 1 using known methods. The presence of the rod 2002, which is inserted into the hole 2000 and is visible only from the upper part protruding from the suspension member, is precisely to prevent the clamp 3000 from being removed from the tubular element 1. Figure 1 The rod 2002, which has not yet been inserted into the hole 2000, is also shown.

[0028] from Figures 2 to 6 As can be seen, the tubular element according to the invention is obtained from a continuous strip 100 of cellulose or paper material, which is advanced by means of a series of roller stations acting at different portions on opposite sides of the strip 100 to gradually shape it, giving it a cylindrical shape with a substantially circular cross-section perpendicular to its longitudinal axis. A flat element 1200 protrudes radially outward from its surface, which is formed by the edges 800, 900 of the strip 100 pressed together by means of the roller stations. To obtain a more robust closure, it is advantageous to use an adhesive material on the surfaces where the edges 800, 900 contact. For this purpose, the angle and position of each roller relative to the strip 100 are appropriately designed so that it acts gradually on it, allowing it to gradually adapt to the shaping, thereby avoiding breakage and preventing it from being subjected to sudden tension.

[0029] However, it should be noted that the roller station can also be replaced by other guiding devices suitable for performing the same function, such as elements made of sheet metal that can progressively form the strip 100.

[0030] In a specific example of the process according to the present invention, the tubular element 1 is obtained through the following steps ( Figures 2 to 5 and Figures 2 to 5 ):

[0031] - The strip 100 is driven by means of a structure including multiple pairs of rollers 1', 1'', the multiple pairs of rollers 1', 1'' are arranged with axes 2', 2'' parallel to each other, the side edges 100', 100'' of the strip 100 are inserted between the multiple pairs of rollers 1', 1'', the rollers 1', 1'' placed on opposite sides of the strip 100 are configured with axes 2', 2'' that are substantially inclined to each other at 90° to determine the curvature of the strip 100, such that its cross-section adopts a right angle configuration, and the edges 100', 100'' are connected by a curved section 200;

[0032] - The strip 100 is driven by means of a structure comprising a plurality of paired rollers 3', 3'', each roller being arranged at one of the opposite edges 300', 300'' of the strip 100, the rollers 3', 3'' being arranged such that their axes 4', 4'' are substantially parallel, thereby giving the strip 100 a substantially U-shaped configuration, the substantially parallel edges 300', 300'' being interconnected by a curved section 400;

[0033] - The strip 100 is driven by a structure comprising multiple pairs of rollers 5', 5'', with rollers 5', 5'' arranged such that their axes 6', 6'' are inclined to each other and act on the edges 500, 600 of the strip 100, such that they are arranged in the same way as the axes 6', 6'' of the rollers 5', 5'', and are connected to each other by an annular structure 700;

[0034] - The strip 100 is driven by means of a structure comprising multiple pairs of rollers 7', 7'', the axes 8', 8'' of the rollers 7', 7'' being parallel to each other and closely arranged, thereby compressing the edges 800, 900 of the strip 100, causing them to adhere to each other. The strip 100 is in the shape of a tubular element with a substantially circular cross-section, and a flat element 1200 protrudes radially outward from its surface. The flat element 1200 is formed by adhering the two edges 800, 900 of the strip 100 to each other.

[0035] At the end of the process that allows edges 800 and 900 to adhere to each other, it is possible to set the step of trimming the joined edges; finally, it is possible to set the step of cutting a portion of the finished length of the continuous strip 100 that matches the tubular element 1.

[0036] Due to the presence of the flat element 1200, the resulting tubular element 1 is relative to Figure 1 The moment of inertia of the bending plane XX is greater than that of a simple hollow cylinder, thus ensuring excellent resistance to typical stresses of the suspension component; the bending plane XX is the plane on which the suspension component bears stress when it bears the weight of the supported clothing.

[0037] Another embodiment of the use of the tubular element 1 according to the present invention, Figure 8 and 9 A flat-shaped hook 5000 is shown, having an elongated shank 5001 adapted for insertion into a slit 2001 at the upper part of the tubular element 1 for measurement. The slit 2001 is opposite to the slit containing the flat element 1200. In fact, the slit 2001 and the shank 5001 have substantially corresponding lengths. After the shank 5001 is inserted into the slit 2001 for measurement, the shank is secured to the inner surface of the tubular element 1 by means of a special adhesive element 5003.

[0038] Figures 10 to 13 Another embodiment of a suspension using the tubular element involved in the invention is shown, which also has a flat-shaped hook 5000. As in the previous case, the latter is advantageously made of pressed cardboard or other similar easily recyclable materials, thus addressing the issue of suspensions made entirely of paper materials.

[0039] Even in this case, the hook 5000 has a shank 5001 adapted to fit into the slit 2001 present in its lower part. However, in this case, at its first end 5011, the shank 5001 has a groove 5010, and due to the presence of the groove 5010, a step 5012 is formed above the end 5011, the step 5012 precisely connecting the end 5011 to the groove 5010.

[0040] Conversely, there is a recess 5015 at the opposite end of the handle 5001, the top of which is defined by the nose 5016.

[0041] from Figures 10 to 13 As can be seen from the sequence, in this case, the total length of the handle 5001 is greater than the total length of the slit 2001. In this case, the slit 2001 is also located on the upper surface of the tubular element 1, at a position opposite to that of the flat element 1200. From an operational perspective, firstly (see...) Figure 11 Fit the shank 5001 portion into the slit 2001, ensuring that one end of the aforementioned slit fits into the recess 5015; then, further lower the hook to ensure that the nose 5016 (see...) Figure 12The portion of the tube 1 adjacent to the end of the slit 2001 can abut against the outer surface of the tubular element 1. Simultaneously, the upper portion of the nose 5016 of the handle 5001 located at the end of the recess 5015 abuts against the inner surface of the tubular element 1. Furthermore, particularly as... Figure 12 and Figure 13 As can be seen, as long as the upper surface of the step 5012 abuts against the inner surface of the tubular element 1, and the step 5012 is close to the end of the tubular element 1 and the slit 2001 opposite to the aforementioned end, the opposite end 5011 of the handle 5001 can be inserted into the slit 2001.

[0042] In fact, the special profile of the handle 5001 ensures that the hook 5000 is stably "locked" in the tubular element 1 by means of the slit 2001, ensuring the overall fixation of the hook 5000 relative to the tubular element 1. All of this is thanks to the material used to manufacture the hook 5000, which has a certain degree of elasticity and deformability.

[0043] However, it should be noted that the handle can be shaped differently from the above illustrations and descriptions, as long as it can be inserted into the slit in a snap-fit ​​manner. Understandably, the total length of the aforementioned slit will still be shorter than the longitudinal length of the handle itself.

[0044] exist Figure 14 and 15 In the illustrated embodiment, the hook 4000 of the suspension is of a so-called typical type, that is, substantially linear, made of a generally metallic material, having a first straight portion 4001 rising from the tubular element 1, which is connected to a curved portion 4002. Advantageously, at the end of the straight portion 4001, the hook 4000 has a threaded portion 4003, which is adapted to be inserted into a second hole 2003 located on the upper part of the tubular element 1 opposite to the flat element 1200.

[0045] Figure 14 A plug 2004 is also shown, adapted to be inserted into the tubular element 1 so as to be partially positioned at its central portion. A first hole 2005 is provided on the side surface of the plug 2004, which must be precisely located at a second hole 2003 present on the surface of the tubular element 1. In this way, the threaded portion 4003 of the hook 4000 can be inserted into the first hole 2005 and naturally passes through the second hole 2003 present on the tubular element 1.

[0046] Figure 15 A general cross-sectional view of the tubular element 1 is shown, with the hook 4000 applied to the tubular element 1 by screwing and engaging with the aforementioned plug 2004, which has a knurled or corrugated outer surface to prevent the aforementioned plug from rotating, especially during its insertion into the tubular element 1, so as to ensure perfect overlap of the holes 2003 and 2005.

[0047] However, once the plug 2004 and hook 4000 are in place, the overall condition of the suspension is as follows: Figure 15 As shown.

[0048] Advantageously, the 2004 stopper will be made of compostable materials and be compatible with processes that recycle paper and similar materials.

[0049] Figures 16 to 19 Two embodiments of a suspension element are shown. The structure of this suspension element is known in itself, having pairs of parallel elements connected by two C-shaped elements positioned at both ends of said elements. Specifically, Figure 16 and 17 The first embodiment is shown, while Figure 18 and 19 A second embodiment is shown. Both embodiments use at least one tubular element 1, but advantageously two tubular elements 2 as constituent parts of the pair of parallel elements; thus, such elements 1 provide the presence of a flat element 1200.

[0050] Advantageously, hooks 4000 and 5000 of the type described in the previous detailed description are provided at the tubular element arranged on it.

[0051] As can be seen from these figures, in two embodiments of such a suspension, two generally C-shaped elements 6000 serve as connecting devices between tubular elements 1, with their horizontal sections 6001 inserted into the hollow bodies of these tubular elements. These C-shaped elements 6000 are advantageously made of cellulose or paper material to maximize the recycling of the materials constituting these suspensions.

[0052] Therefore, it can be seen that by using the tubular element and process according to the present invention, the problem of using tubular elements made of cellulose or paper materials as suspension structural elements can be easily solved.
