Double-leaf bonded hinge

Abstract

The aim of the present invention is an improved double-leaf adhesive hinge for fixtures, shutters, hatches or the like, formed by one or more bodies and able to operate a rotary connection between two elements by using a series of alternating folds on the front and rear of the two elements themselves, as a replacement for the standard rotary pivot or hinge, operable to enable the opening or rotation of the elements even up to 360°. Preferably, a single body is formed and the single body can be applied to one or more angular or linear sides by simple adhesive application to enable the connection of fixtures and shutters or the like with their specific rotary function. The elements connected by the hinge according to the invention rotate by the alternation of one or more pairs of hinges formed by folds positioned opposite each other, thus forming a translational but non-overlapping double Z (Zed) system.

Description

Technical Field

[0001] The object of this invention is an improved double-leaf adhesive hinge for use in fixtures, blinds, doors, or the like. The hinge is particularly suitable for engaging elements that require relative rotation, such as lightweight panels. Background Technology

[0002] Currently known hinges for fasteners and blinds typically include: a receiving body, a pivot retaining unit inserted into a corresponding base, and tools for adjusting the arrangement, position, and center distance; these are often difficult to assemble. The receiving body consists of a single component, the interior of which defines a base for the pivot retaining unit.

[0003] Despite their popularity and commonality, such known hinges also have some inconveniences. The first inconvenience is that the housing, pivot holding unit, and adjusting element are all separate components that must be assembled and adjusted, making the assembly and fixing process both time-consuming and labor-intensive, thus impacting the final cost of the product.

[0004] Another limitation of common standard hinges of known types is their technical / structural characteristics, which prevent the connected elements, fixtures, blinds, doors, or the like from rotating up to 360°.

[0005] Another limitation of standard hinges of common known types is that such solutions are often incompatible with lightweight, thickened materials, such as expanded polystyrene and hollow panels, which are difficult to accommodate screws, nuts, or pins.

[0006] Purpose of the invention

[0007] The object of the present invention includes manufacturing an adhesive hinge for fixing devices, blinds, doors or the like, which can eliminate the aforementioned inconveniences and limitations of the prior art.

[0008] Within the scope of such a task, the object of the present invention includes providing an improved adhesive hinge that is simpler and easier to assemble than prior art hinges.

[0009] Another object of the present invention is to provide an improved adhesive hinge that can be easily and intuitively managed not only by the installer but by anyone, without requiring the use of known tools such as Allen wrenches and screwdrivers.

[0010] This task, as well as other purposes which will be better described below, is accomplished by an adhesive hinge for fixing devices and blinds, the adhesive hinge comprising at least one body, preferably a single molded body or multiple bodies, which, as required and at the level of technology, is made of any material, provided that the material is compatible with the particular purpose, and otherwise has any size and shape. Summary of the Invention

[0011] This invention relates to a hinge configured such that at least two elements engaged with the hinge itself can rotate relative to each other according to two different directions or types of rotation (double rotation); the hinge is characterized by comprising two different types of folds. In the use state of the hinge, the hinged elements can rotate relative to each other clockwise and counterclockwise. Each fold engages with a different type of fold during both clockwise and counterclockwise rotation.

[0012] The hinge achieves this dual rotation by providing at least two different types of folds, each of which acts as a hinge unit and is preferably "Z"-shaped. The different types of folds have mirror or inverted configurations; this enables relative rotation of the hinged elements in two rotational directions. Providing two types of folds with mirror or inverted configurations allows the hinge to be shaped like a "double Z" in the front view (…). Figure 3 Each of the two types of folds is a "Z" shape, and along the longitudinal direction K (in a construction with a single body, the longitudinal direction is defined by the main extension direction of the central portion of the body, while in a construction with multiple bodies, the longitudinal direction is defined by the sequential direction of the bodies; see respectively) Figure 2a and 2b )alternately.

[0013] As discussed above, the molded body can be a single body (in other words, a single monolithic component). Regardless of whether the body is single or not, it can be made of adhesive material from the outset, or adhesive tape can be applied to the body to integrate it with the element to be connected and make it usable with the element to be connected.

[0014] The single body, for example, uses a series of alternating folds at the front and rear as an alternative to a standard pivot. Figure 6 ).

[0015] The elements connected by the hinge bonding system, preferably a double-sided system, are rotated alternately by two pairs of hinges (two pairs of hinge units) formed by the folds, the two pairs of hinges being positioned relative to each other to form a translational (offset, in other words, where the first and second type hinge units, respectively forming "one Z" in a "double Z", follow each other longitudinally along the central portion of one or more bodies of the hinge) but non-overlapping (in other words, when the "two Zs" overlap, they do not overlap, see...). Figure 3 A double Z-shaped (Zed) system. The adhesive system has the dual function of clamping (adhesively joining) the elements and additionally holding the elements in place relative to other connected movable elements. Around the Y-axis ( Figure 1 The rotation is achieved through the presence of a fold in the body of the adhesive hinge, through which one or more hinged elements can rotate freely with constant contact (and thus with stable engagement).

[0016] Furthermore, the present invention relates to: an assembly comprising at least one hinge and two hinged elements or two elements to be hinged by said hinge, the use of said hinge, and a process for manufacturing said hinge. The steps of said process (cutting, shaping, manufacturing to have adhesive properties, folding the portion to be folded, etc.) may be described below with reference to the characteristics of the hinge.

[0017] Conventions and Definitions

[0018] In the context of this disclosure, one or more of the following definitions and conventions may be applied as needed:

[0019] - "Double-leaf hinge" means a hinge that is configured to allow two elements engaged with the hinge to rotate relative to each other by an angle of up to 360°.

[0020] - "Adhesive hinge" means a hinge configured to adhesively engage with at least one rotatable element, preferably two rotatable elements. The adhesive hinge may be provided with an adhesive system already provided in the manufacturing process (preferred embodiment), or it may be manufactured to be adhesive after manufacturing, for example, before use.

[0021] - The “element” that a hinge can engage means a fixture, louver, hatch, panel, tubular object or similar, or a portion thereof (this list is obviously illustrative rather than exhaustive); such elements will also be referred to herein as “hinged elements,” “pivotal elements,” and similar expressions. Preferably, the element to be hinged is of a lightweight type, wherein the term lightweight element (particularly panel) means an element (or panel) weighing in the range of a few kilograms to less than ten kilograms; such mass, and therefore the corresponding weight, can be understood as mass / weight (in units of mass / weight in units of length) calculated in linear meters of the hinge’s length.

[0022] - The “fold” operatively acts as a hinge, in other words, the fold is capable of enabling one of two hinged elements to rotate relative to the other in two rotational directions; in this document, each “fold” may be defined as a “hinge unit” as needed and in order not to be mistaken for a “hinge” device (of which the fold is a part);

[0023] - "Alternating folds" or "alternating folds" means that folds can be arranged alternately, in other words, folds arranged according to a defined alternation. Alternation is defined between different types of folds, particularly between (at least) two types of folds; thus, a first type of fold can alternate with a second type of fold. The hinge shown in the attached figures provides two (mirror) types of folds that are different from each other; conventionally, the folds are indicated as "Type A" folds (or also referred to as "a," "A," "Za," or "A Zed," the latter term used when the fold is in a flat, unfolded, or partially folded configuration) and "Type B" folds (or also referred to as "b," "B," "Zb," or "B Zed," the latter term used when the fold is in a flat, unfolded, or partially folded configuration); one or more Type A folds alternate with one or more Type B folds (see...). Figure 5 , 6 and 9b);

[0024] - "Adhesive" means "constructed to adhere" (e.g., by means of an adhesive or glue or similar means); with the necessary modifications, similar reasoning can be applied to terms such as "adhesively" or "manufactured to be adhesive". Attached Figure Description

[0025] Further features and advantages of the invention will become more apparent from the description of preferred, but not exclusive, embodiments of the improved hinge according to the invention, which are illustrated in an indicative rather than limiting manner in the following drawings, wherein:

[0026] - Figure 1 The diagram illustrates the proportions of components of a hinge according to a possible embodiment of the invention, where the letter X represents the width of the hinge, the value of which may be equal to the thickness of the element to be hinged (e.g., a panel), and the letter Y indicates the length of the fold Z (in other words, the length of the portion of the hinge that is intended to form the "Z" fold). The width X and the length Y of the fold may include between 1 millimeter and several centimeters; for the same hinge, the width X may vary along the longitudinal extension of the hinge.

[0027] - Figure 2a This diagram illustrates, according to an embodiment of the invention, a hinge with four segments (labeled A0, A1, A2, B0, B1, B2 for two of the segments) comprising a single body, provided as an exemplary, not exhaustive, solution. The central portion, indicated by the letter F, connects all the segments and helps maintain the integrity (monolithic body) of the hinge according to the invention during manufacturing processes; two folding attachments protrude to the right of the central portion F, while two other folding attachments protrude to the left of the central portion F. The effective folding points of the invention are indicated by dashed lines. The letter C indicates a folding portion rotating from right to left, and the letter D indicates a folding portion rotating from left to right; left and right are defined according to the orientation of the hinge, particularly the body portion of the hinge, as shown in the figure.

[0028] - Figure 2b This is a schematic diagram of a hinge with multiple bodies, each body being constructed and adapted to form a corresponding fold; therefore, the central portion F of the hinge is divided into multiple lengths that are separate from each other, each length belonging to a corresponding body. Conceptually, such a hinge is achieved by... Figure 2a The central part of the hinge is divided into multiple segments corresponding to the number of attachments to be folded;

[0029] - Figure 3 An orthogonal view of the hinge according to the invention is shown, wherein the rotation point (or pivot) is indicated, and wherein, in the bottom portion of the figure, a plurality of “Z”s are positioned one after another (in other words, they are alternating or “translating”).

[0030] - Figure 4The diagram illustrates the folding procedure of a single-piece body of a double-leaf adhesive hinge according to the invention (which enables the folding of the constituent materials) and the direction in which the folding is performed so that the pivoting element can perform a full rotation, even up to 360°. This procedure is part of the process of manufacturing the hinge according to the invention. The first fold is performed by flipping all the A-type "Z"s to the right according to the folding line or point indicated by abbreviation p1 (the folding operation involves flipping the body portion to be moved inverted). The second fold involves all the B-type "Z"s, which are flipped to the left (folded and flipped inverted) at the folding line or point indicated by abbreviation p2. The third fold is formed by the portion of the A-type "Z" indicated by abbreviation "A1", which is flipped to the left (folded, preferably flipped inverted) according to the folding line or point indicated by abbreviation p3. In the fourth (final) fold, the portion of the B-type "Z" indicated by abbreviation B1 is flipped to the right (folded, preferably flipped inverted) according to the folding line or point indicated by abbreviation p4. Such folding steps enable the folding of parts A1, A2, B2, and B1 of the appendages of the main body; Figure 4 The mirror orientation of the abbreviations A1, A2, B2, B1 in the diagram shows how such parts are flipped into an inverted state around the fold lines p1, p2, p3, p4;

[0031] - Figure 5 The final process for manufacturing the double-leaf adhesive hinge according to the invention is shown. This final process includes making the body of the hinge object of the invention adhesive (manufacturing it to be adhesive) (preferably by applying an adhesive material or by removing a protective film H of adhesive that may already be present on the material forming the body of the hinge according to the invention), which functions to hold the disassembled parts formed after folding together as a single unit, as indicated by letter G in the figure. For example, two other parts of the film (whether or not they are manufactured to be adhesive) (coverings, letter H) are present in the upper and lower parts of the body of the hinge object of the invention, and their task is to keep the hinge integral with the element to be hinged.

[0032] - Figure 6 This is an exemplary view of the application of the invention on two panels, wherein the thickness of the two panels forms the clamping point (adhesive joint) of the double-leaf adhesive hinge. Therefore, Figure 6 An assembly according to the invention is shown, wherein the panels are hinged to each other by a pair of type A hinge units and a pair of type B hinge units. In this exemplary but not exhaustive representation, the hinges demonstrate the possibility of rotating the two panels up to 360° in one direction and in opposite directions; regarding the 360° rotation, see the order of two constructions of the panels illustrated as closing "like a book" (see the two illustrations between "B in operation" and "A in operation"). Figure 6As shown, during the counterclockwise rotation of the panel (to the left, see the sequence of "Intermediate Step" and "B in Operation"), a pair of B-type hinge units primarily operate (note that this pair also operates during the clockwise rotation of the panel to return to the "Intermediate Step"), while during the clockwise rotation of the panel (to the right; see the sequence of "Intermediate Step" and "A in Operation"), a pair of A-type hinge units primarily operate (note that this pair also operates during the counterclockwise rotation of the panel to return to the "Intermediate Step").

[0033] - Figure 7 A series of steps are shown that enable the hinge according to the invention to be used (manufacturing an assembly) by adhesively joining the hinge to two panels for hinged connection. As illustrated by the example, the hinge is preferably double-sided, in other words, adhesive on both the upper and lower surfaces;

[0041] Referring to the accompanying drawings, the double-leaf adhesive hinge according to the invention is generally indicated by reference numeral 1 in its possible embodiments and is configured for any type of hinge for element 21, wherein the hinged element has the possibility of relative rotation up to 360°.

[0042] Hinge 1 includes a single-piece body 2 or multiple body 2 I 2 II,twenty one III 2 IV Or it can consist of a single main body 2 or multiple main bodies 2 I 2 II ,twenty one III 2 IV Each of the main bodies is configured to be folded into a "Z" shape. For example... Figure 2a As shown, in an embodiment providing a single body 2, the single body 2 may include a central portion F and appendages A Zed and B Zed extending laterally from both sides of the central portion; the appendages extending from one side (in the figure, the appendage B Zed on the right) are adapted to form a B-type fold, while the appendages extending from the other side (in the figure, the appendage A Zed on the left) are adapted to form an A-type fold. One or more bodies are preferably made of an elastically deformable material, and additionally or alternatively, may have a thickness as a function of the material, on the order of micrometers (μm), for example, about 100 micrometers, or on the order of millimeters. In addition to elastic deformability, the material of one or more bodies preferably also has a required specific stiffness depending on the intended application of the hinge, so as to make the hinge robust. For example, the hinge material, particularly the material of one or more bodies, may be recyclable and / or have a natural source, such as typically one of polyvinyl chloride (PVC), polyethylene (PET), paper or cardboard, fabric, or leather.

[0043] Figure 1 The simplest embodiment of the invention is shown, which includes a hinge 1 having a single-piece body 2 having two parts A Zed and B Zed that can be folded in a “Z” configuration, each of the two parts being adapted to engage a corresponding element 21 to be hinged.

[0044] The double-leaf adhesive hinge 1 is characterized and advantageous in that it can be manufactured continuously (though not merely continuously) by producing a strip with variable length and width, the strip being obtained from sheet or roll material. The strip is then custom-cut to obtain the body 2 or body 2 required for manufacturing the hinge. I 2 II ,twenty one III 2 IVThe dimensions of the hinge 1 are varied. Different lengths allow the object to be optimally suited for even large panels (e.g., panels with a maximum planar cross-section of 2 meters × 3 meters), thus enabling the distribution of forces determined by weight and by the protrusions of panel 21 across the entire length of the fold of the connecting element 21. To support the weight of the element or panel 21 engaged with the hinge 1 and the structural stresses determined by their movement, the material of one or more bodies of the hinge 1 and the material of the adhesive to be used can be appropriately selected. The adhesive to be used can be selected based on the application type, such as the expected weight of the lightweight element or panel 21 to be hinged.

[0045] Hinge 1 includes two types of folds that are preferably mirror images of each other; in this regard, see Figure 3 . Figure 3 The upper left portion indicated by the letter A shows the portion indicated by the letter A. Figure 1 The A-type fold formed by the main body portions A1 and A2 (hereinafter referred to as "A-type hinge unit"; it indicates a hinge capable of enabling one type of rotation, preferably clockwise, of the two hinged elements to open), while Figure 3 The upper right portion indicated by the letter B shows the portion indicated by the letter B. Figure 1 The main body portions B1 and B2 form a B-type fold (hereinafter referred to as a "B-type hinge unit"; it indicates a hinge that enables a type of rotation of two hinged elements to open them, the type of rotation being opposite to that enabled by a type A hinge unit, preferably a counterclockwise rotation). Figure 3 The bottom portion indicated by A+B is hinge 1 and Figure 2a , 2b Rear view of the hinge. Figure 2a , 2b The hinge is constructed by folding one or more body sections A1, A2, B1, B2; it illustrates a "translational double Z" hinge, where the "Z" folds are mirror images of each other. In addition to primarily handling the aforementioned clockwise / counterclockwise rotations, each type of hinge unit also engages in another counterclockwise / clockwise rotation primarily managed by the other type of hinge unit (see below for...). Figure 9a and 9b (Description of the structure). Preferably, the hinge 1 has an equal number of type A hinge units as type B hinge units. More preferably, in order to achieve stable rotation, the hinge 1 may include at least two type A hinge units and at least two type B hinge units.

[0046] The different types of folds of hinge 1 alternate longitudinally relative to each other; in other words, they follow the direction defined by a single body. Figure 2a Or defined by the arrangement along the longitudinal direction of multiple main bodies. Figure 2b Alternating vertical directions. (Reference) Figure 2a and 2b In hinge 1, after folding portions A1, A2, B1, and B2, two type A hinge units alternate with two type B hinge units in the following order: type A hinge unit, type B hinge unit, another type A hinge unit, another type B hinge unit (this order can be derived from...). Figure 2a and 2b (This was derived by moving along the central portion F from the bottom to the top).

[0047] Hinge 1 includes at least one type A hinge unit and at least one type B hinge unit. The type A hinge unit is configured to enable at least clockwise rotation of an element to which it engages, and the type B hinge unit is configured to enable at least counterclockwise rotation of the element to which it engages. Each fold is elastically deformable and configured to operate between an operating configuration and a stationary configuration, in which the fold enables clockwise or counterclockwise rotation of the element, and in the stationary configuration, the other fold is primarily operating to enable clockwise or counterclockwise rotation of the element.

[0048] Folds can be arranged and alternated such that successive folds (and thus successive hinge units) interfere with each other; in the static state of the hinge, for example, when the hinged elements form an angle of 0° with each other (“closed” elements) or an angle of 360° or about 360° (“open” or “fully open” elements), this interference can provide at least partial “locking”, which holds the elements in place and can at least partially prevent accidental rotation. In the state of use, interference between different types of longitudinal successive hinge units can determine an audibly defined sound that is essentially a “crack” or “click,” especially when the direction of relative rotation of the hinged elements is reversed; this sound can provide evidence that the hinge according to the invention is in use.

[0049] Each fold preferably has a "Z" shape, having first portions A0, B0, second portions A1, B1, and intermediate portions A2, B2 (the diagonal portions of the "Z") connecting the first and second portions. The second portions A1, B1 are guide portions that rotatably guide the element 21 it engages with when the corresponding fold is in the operating configuration; for this purpose, see [reference needed]. Figure 9a and 9bThe second portion B1 of the "B-type" fold guides the tubular element to which it is rotatably engaged. In this configuration (B in operation), the A-type fold engages to follow the rotation of the tubular element, since the A-type fold also engages with the tubular element via the first portion A1 and thus follows its rotation; it can be observed that, with necessary modifications (in other words, particularly for what has just been described), both fold types engage for rotation guided by the guiding portion A1 of the A-type fold (A in operation). The opposite ends of the intermediate portions A2 and B2 engage with the first portions A0 and B0 and the second portions A1 and B1 respectively, and act as pivots of rotation; in this respect, each "Z" fold has two pivots of rotation (see...). Figure 3 Each fold can be at least partially circular; in particular, at least the middle portion can be circular (see [reference needed] for this). Figure 9a and 9b ).

[0050] like Figure 2a and 2b As illustrated in the example, the hinge includes at least two pairs of fold lines, preferably at least four pairs of fold lines p1, p2, p3, p4. Typically, the hinge may include a pair of fold lines for each fold to be manufactured; each pair of fold lines cooperates to define a corresponding "Z" fold, and defines it at the same appendage of a single body 2, or, in the case of multiple bodies, at the same body 2. I 2 II ,twenty one III 2 IV At the same location as the appendage.

[0051] exist Figure 4 The reference to appendages A Zed and B Zed schematically illustrates a folding pattern for a hinge 1 having a single body 2; the same folding pattern can also be applied to a body 2 having multiple appendages A Zed and multiple appendages B Zed. Figure 2a ). In providing multiple subjects 2 I 2 II ,twenty one III 2 IV ( Figure 2b In embodiments of the hinge, these bodies can be applied close to each other and can be folded using the same or similar techniques as those disclosed herein.

[0052] Furthermore, hinge 1 may include an additional adhesive element 3 (or reinforcing element) configured to engage one or more bodies of hinge 1 and adapted in use to be inserted between the lower surfaces of one or more of the elements 21 to be hinged and one or more of the bodies. It can be observed that in embodiments providing the additional adhesive element 3, the engagement between one or more bodies and element 21 is an indirect engagement, as the engagement is mediated by the additional adhesive element 3. The additional adhesive element 3 acts as an intermediate member between the element 21 to be hinged and one or more bodies, and promotes, stabilizes, and strengthens the relative engagement. With an increase in size (e.g., the width and length of the additional adhesive element 3), the stabilizing effect of the engagement between hinge 1 and the element 21 to be hinged correspondingly increases; in this regard, see [reference needed]. Figure 8b The additional adhesive element 3 in the middle has a size larger than Figure 8a The size of the additional adhesive elements. Figure 8a and 8b An additional adhesive element 3 is shown that engages with the body 2 of the hinge 1 (the body 2 is drawn in dashed lines because it is illustrated as being behind and thus covered by the additional adhesive element 3). Preferably, one of the front and rear surfaces of the additional adhesive element 3 is adhesive to enable adhesive engagement with element 21; see reference. Figure 8a and 8b The foreground surface of the additional adhesive element 3 is adhesive. Preferably, only one of the front and rear surfaces of the additional adhesive element 3 is adhesive; the engagement between one or more bodies of the hinge 1 and the additional adhesive element 3 (occurring at opposing surfaces) can be achieved by the adhesive surface of one or more bodies or in another manner. From the perspective of the mode of applying the hinge to the element 21 to be hinged, the additional adhesive element 3 can first engage the element 21, and then one or more bodies of the hinge 1 can be engaged to the additional adhesive element 3; alternatively, engagement can be provided between the additional adhesive element 3 and one or more bodies of the hinge 1, and then the additional adhesive element 3 can be adhesively engaged to the element 21 to be hinged.

[0053] Furthermore, the present invention relates to a component 33 comprising at least two elements 21 to be hinged and at least one hinge 1 of the aforementioned type, optionally multiple hinges 1. At least one hinge 1 engages with such an element 21 to hinge the element 21.

[0054] Furthermore, the present invention relates to the use of hinge 1 for hinged connection of two elements 21; the use envisions hinge 1 adhesively joined to at least two elements 21. Figure 7The diagram illustrates a series of steps that enable the hinge 1, having a single-piece body 2, to be put into use. These steps will be described below in the order shown from left to right in the diagram: removing the covering film H to expose the flat, adhesive lower surface of the hinge 1 body; applying predetermined pressure to adhesively engage the hinge 1 body with the first panel 21 at the flat lower surface; removing another covering film H from the adhesive upper surface of the hinge 1 body; and then applying predetermined pressure to adhesively engage the second panel 21 with the adhesive upper surface of the hinge 1 body. For each body 2 of a hinge 1 having multiple bodies... I 2 II ,twenty one III 2 IV Similar steps can be performed.

[0055] Furthermore, the present invention relates to a process for manufacturing a hinge, the process of which envisions folding one or more bodies of the hinge according to the description above.

[0056] Another advantage of the hinge according to the invention is its adhesiveness, thus eliminating the need for any type of mechanical anchoring (screws, bolts, etc.). Consequently, the hinge is manufactured faster and at a lower cost.

[0057] Another advantage of the hinge 1 according to the invention is that the hinge 1 can be operated using only the edge (side) of the hinged element 21, without occupying the front and rear surfaces. In such an embodiment, one or more bodies of the hinge 1 do not engage with the surface of the element 21 that engages with the hinge 1, which is transverse to the side of the element, and the width of one or more bodies can be the same and can be aligned with the width of the side of the element 21 in use. Alternatively, the central portion F of the hinge 1 to engage with the element 21 to be hinged (or additional adhesive elements 3 for engaging one or more bodies to the element 21) can have a greater width than the edge or side of the element 21, and can therefore engage at least partially correspondingly with at least one (front or rear) surface transverse to the side, preferably with two surfaces transverse to the side and opposite to each other, or can simply protrude from the side to form a free edge.

[0058] Furthermore, hinge 1 is adapted to be applied to, for example, the straight and / or curved edges of the element to be hinged; in any case, hinge 1 is preferably adapted to follow the straight and / or curved profile of the portion of the element 21 to which it engages. Figures 10a-10f , Figures 11a-11e and Figures 12a-12c As illustrated in the example, hinge 1 is illustrated by a line having a thickness greater than that of the line of element 21, and hinge 1 follows and surrounds the shape of the portion of element 21 to which it engages.

[0059] It has been determined that the present invention fulfills specific tasks and objectives. In particular, the present invention provides an improved hinge 1, which is simpler and faster to assemble than prior art hinges, due to one or more bodies made of a shaped material (“comb-shaped”, having teeth protruding from both sides of the central portion F, wherein each appendage forms “comb-shaped” teeth), and particularly a single body 2 is formed by two or more useful folds through simple operation, so that they are joined together by the simple application of an adhesive layer.

[0060] Furthermore, this invention provides an improved hinge that is not only easy to manage by technicians, but also easy for anyone to manage in a simple and intuitive way, without the need for known types of tools such as Allen wrenches and screwdrivers.

[0061] As designed, the invention is readily subject to numerous modifications and variations, all of which fall within the scope of the invention's concept; furthermore, all dimensional or structural details can be modified with other values ​​or technically equivalent solutions.

[0062] In essence, the components and materials used, as long as they are compatible with the specific purpose, and other possible sizes and shapes, can be any components and materials, as well as any size and shape, depending on the needs and the current level of technology.

[0063] As illustrated herein, the invention can be made from any useful material, which may be best utilized, depending on the requirements or limitations of the context or application in which it is intended or must be inserted. Furthermore, the invention can obviously be made in any shape or size without departing from the purpose and scope of the claims.

[0064] For example, the number of folds (Y-axis), the arrangement of folds, and the number of connections / juxtapositions between different components are not specifically described herein, as they can be easily inferred by those skilled in the art based on possible assembly and operational needs.

[0065] Only basic or structural components are described herein; therefore, the system, in other words, the hinge 1 and / or component 33 according to the invention, may also include additional features to complete or finish it.

[0066] Furthermore, it should be noted that the present invention has particular applications in the following areas and / or uses: display cases, billboards, signage, DIY projects, virtually any hobby, partition walls, virtually any partition element, boxes or parts or panels thereof, hatches, temporary or scheduled repairs, or any other application requiring relative rotational (particularly circumferential) movement between two elements 21. The hinge 1 according to the invention is particularly advantageous because it is suitable for both temporary use, such as as a temporary repair with regard to a scheduled future repair or replacement, and for scheduled use. Essentially, the hinge 1 acts as a "universal articulated connector," suitable for several applications and multiple uses.

[0067] Clearly, the foregoing description of embodiments applying the novel principles of the present invention is disclosed as an exemplary manner of such novel principles and therefore should not be considered as a limitation on the scope of the claims herein. Consequently, embodiments and construction details may be broadly modified from what has been described and illustrated without departing from the scope of the claims, without affecting the principles of the invention.
