DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0071] The improved folding device of the invention, intended to cover bulky and three-dimensional bodies, such asthough not in a limiting waya car A, is illustrated by means of a first embodiment in FIG. 1, where it is generally designated by the reference numeral 1.

[0072] In accordance with the invention, as it can be seen in FIG. 1, the improved folding device 1 comprises a multilayer element 2 composed of a plurality of multilayer covering sections 3 that are spaced, distinct and independent one from the other, and kept steadily in position by locking means, generally designated by the reference numeral 4, arranged or applied in such a manner as to define between the multilayer covering sections 3 a series of longitudinal interstitial discharge recesses 5 suitable to allow the mutual rotation of the multilayer covering sections 3 along a plurality of longitudinal lines K parallel to each other and a plurality of latitudinal lines W parallel to each other and orthogonal to and crossing the longitudinal lines K, in such a way that the multilayer element 2 takes on: [0073] an operational condition suitable to cover the bulky body Aor at least its most critical, sensitive points which are most subject to damage, even irreversible damage (for example the front window T, the hood C, the side windows F and the rear window L of the car)to protect it against invasive atmospheric agents (such as hail and scorching sun), wherein the multilayer covering sections 3 are mutually substantially coplanar and placed side by side along the first longitudinal directions X, parallel to each other, and along second longitudinal directions Y parallel and orthogonal to the first longitudinal directions X; [0074] a non-operational condition suitable for storing the multilayer element 2, wherein the multilayer covering sections 3 are neatly folded one on top of the other according to a predefined sequence along the longitudinal lines K and the latitudinal lines W, in such a way that the inner face of the multilayer covering sections 3, which are progressively affected by folding, is substantially adjacent to and facing the inner face of the multilayer covering sections 3 on which they are folded and that the multilayer covering sections 3 are thus stacked one upon the other and overlap to create an orderly and compact package 6, taking up minimum space, that determines, consequently, the saving of space when storing it and easy handling.

[0075] In particular, the width of each one of the longitudinal interstitial discharge recesses 5 positioned along one of the longitudinal lines K or one of the latitudinal lines W is no less than the sum of the thicknesses of the multilayer covering sections 3 adjacent thereto and simultaneously folded again by the user by rotation around the longitudinal lines K or the latitudinal lines W.

[0076] FIG. 1 also shows that the longitudinal interstitial discharge recesses 3 (in this specific case, in a preferred manner, defined only in their upper surface 2d of the multilayer element 2) positioned in one of the longitudinal lines K or in one of the latitudinal lines W, conveniently have, thanks to the precision of the application system of the locking means 4, the same width L.sub.1 o L.sub.2.

[0077] Moreover, from the point of view of the constructional design of the multilayer element 2 of the improved folding device 1 of the invention, the length of one of the multilayer covering sections 3, taken as reference, is shorter than the length of one of the multilayer covering sections 3 on which such multilayer covering section 3, taken as a reference, is directly folded along the first longitudinal directions X.

[0078] What must be also pointed out is that, according to the main longitudinal development of the multilayer element 2 in its operational condition, such direction of development coinciding with the direction of the main longitudinal development of the bulky and three-dimensional body A that is to be protected, the folding sequence of the multilayer covering sections 3 occurs according to an ascending order of the length of each one of the multilayer covering sections 3, as it will be better explained below thanks to FIGS. 3 and 4 and, in a more detailed manner, thanks to FIG. 5.

[0079] Even more in detail, in the non-operational condition of the multilayer element 2: [0080] Each one of the multilayer covering sections 3 positioned along one of the first longitudinal directions X is fully comprised within the space of one of the multilayer covering sections 3 adjacent thereto, along said first longitudinal direction X, it is folded above it, and facing and substantially positioned adjacent to it; [0081] Each one of the multilayer covering sections 3 positioned along one of the second longitudinal directions Y is fully comprised within the space of one of the multilayer covering sections 3 adjacent thereto, along said second longitudinal direction Y, it is folded above it, and facing and substantially positioned adjacent to it;

[0082] Moreover, the multilayer covering sections 3 positioned along one of the first longitudinal directions X or along one of the second longitudinal directions Y are movable in a way that is integral between them during folding, from the non-operational condition to the operational condition and vice versa, and obtained by rotation of the multilayer covering sections 3 around one of longitudinal lines K or one of the latitudinal lines W.

[0083] These constructional aspects can be clearly seen in FIG. 5 that, even if it refers to the improved folding device 1, which is intended specifically for covering a vehicle A (which is highly widespread in the actual car market) of the type shown in FIG. 4, highlights thanks to its measuresit should be noted that this is mentioned only in an explanatory and not limited waythe technical principle underlying the present invention.

[0084] According to the preferred embodiment of the invention herein described, as it can be inferred by observing FIG. 2, the multilayer element 2 comprises: [0085] A lower layer 7 made of soft anti-scratch and water-repellent fabric, provided with a lower face 7a adapted to come into contact with the bulky body A to be protected (for example the folding topor folding hoodand the car windows); [0086] A plurality of semi-rigid tiles 8 used for padding, positioned above the bottom layer 7 and made of insulating material, suitable to shield the bulky body A against severe atmospheric agents and to adapt to the shape of the bulky body A to be protected; [0087] An upper layer 9 made of water-repellent, reflective fabric positioned above the semi-rigid padding tiles 8 and provided with an upper face 9a facing outwards and suitable to be damaged or affected by severe atmospheric agents,
the lower layer 7, the semi-rigid padding tiles 8 and the upper layer 9 being mutually coupled by the locking means 4.

[0088] Preferably but not necessarily, the multilayer element 2 comprises a laminar layer of thermally insulating material 10, made for example of polyethylene fabric, positioned between the semi-rigid padding tiles 8 and the upper layer 9 and made integral with the lower layer 7, the semi-rigid tiles 8 and the upper layer 9 again by the locking means 4, that are schematically shown in a schematic and simplified manner in FIG. 1.

[0089] More in detail, each one of the semi-rigid padding tiles 8which constitute the core of each multilayer covering section 3preferably has a rectangular shape and is composed of a lower reinforcement substrate (not shown and made, for example, of an aluminium sheet), an amorphous intermediate layer (not represented and made, for example, of a parallelepiped shape of rock wool or glass wool) and a top reinforcement layer (also not shown) having a thickness which is substantially equal to that of the lower reinforcement substrate.

[0090] In particular, in a preferred but not binding manner, each one of the semi-rigid padding tiles 8 has a thickness equal to a range of 24 mm, preferably 3 mm.

[0091] Still in particular, the water-repellent reflective fabric of the upper reinforcement layer is coloured and has a colour similar to the aluminium's.

[0092] Therefore, in the light of the materials used for constructing the various multilayer covering sections, what is obtained is an extreme lightness of the improved folding device of the invention, despite the considerable surface extension of the device, when it is in the application position or while it is being unfolded to be placed in such a position (that coincides with the operational condition of the multilayer element 2).

[0093] With regard to the locking means 4, they are arranged along the perimeter of each one of the multilayer covering sections 3 in such a way as to define, between the multilayer covering sections 3, the longitudinal interstitial discharge recesses 5: this application takes place after that the various multilayer covering sections, during the construction of the improved folding device 1 of the invention, were at least positioned in a predetermined position and associated to the above described various layers of fabric.

[0094] In particular, the semi-rigid padding tiles 8 are inserted into the internal pockets, that are not visible, and created in the lower layer 7 of each one of the multilayer covering sections 3 and closed by means of rapid coupling means, such as for example Velcro.

[0095] In a preferred, however non-limiting way, the locking means 4 comprise any of the systems of mutual fixing of componentsthe fixed and not removable onesselected from the group consisting of a seam portion, a heat-sealed portion, a glued portion, their combinations thereof and/or the like.

[0096] So, in an optional and not exclusive way, the multilayer element 2 is provided, in at least one of the multilayer covering sections 3 (in general, in two of them) positioned along only one of the first longitudinal directions X, with a through slot (not shown in the figures of the attached drawings) built in the thickness of the multilayer element 2 starting from one of its side edges having a shorter length 2a.

[0097] More in particular, the through slot is, as a rule, created in the multilayer covering sections element 3, which are arranged along the first longitudinal central direction X and coincide with the symmetry axis of the multilayer element 2 and, in the operational condition of the multilayer element, cover the rear window L and the rear end part of the car hood, when it constitutes the bulky body A.

[0098] The through slit allows the multilayer element 2 to be correctly and effectively positioned in its operational condition, above the bulky body A, even if an element protruding upwards from the bulky body A is present (for example, if a receiving antenna is present and applied to the car hood).

[0099] Preferably but not exclusively, the improved folding device 1 of the invention also comprises a containment folding box, which is not shown in the following figures, steadily associated to the lower face of one of the multilayer covering sections 3, and suitable to take the operational position when the multilayer element 2 is in its non-operational condition and creates the orderly and compact package 6 composed by the multilayer covering sections 3 (that are generally shaped as a parallelepiped) and which is steadily housed inside it.

[0100] However, when the multilayer element 2 takes on the operational condition, the containment folding box is in the rest position, stretched out and substantially positioned close to the lower wall of the multilayer covering section to which it is associated, in such a way as to take up the least possible space.

[0101] Therefore, when the multilayer element 2 is completely folded on itself (non-operational condition), it is hermetically housed in this containment folding box, where it can be locked by means of quick connection systems (such as Velcro), associated with side bands coupled to the containment box, which allows to solve the problem of storingand thus physically isolate from the neighbouring structuresthe improved folding device 1 of the invention, especially when it is soaked with rain or wet because of atmospheric events.

[0102] Advantageously, although optionally, the containment folding box is coupled to at least one of the multilayer covering sections 3, having a higher surface extension and on which all the remaining multilayer covering sections 3 fold when changing from the operational condition to the non-operational condition of the multilayer element 2 and are arranged at the top when the multilayer element 2 changes from the operational condition to the non-operational condition.

[0103] FIG. 6 shows a first possible variant embodiment of the invention in which the improved folding device herein exclusively claimed, and now generally designated by the reference numeral 50, differs from the previously described one, which is indicated by numeral 1, in that it also comprises anti-shoplifting means that are generally indicated by numeral 56, operatively connected to the multilayer element 51 and suitable to be steadily coupled to the bulky and three-dimensional body A when the multilayer element 51 takes on the operational condition, and they are thus not accessible from the outside.

[0104] The anti-shoplifting means 56, in addition to completely and fully prevent the improved folding device 50 from possibly and forcibly being removed from the bulky body A by criminals, while being in its operational condition, and positioned over the bulky body, also contribute to substantially increase the stability of the multilayer element 51 in its operational condition and to prevent accidental separation or incorrect positioningmisaligned with respect to the bulky body A, e.g. if strong wind blowsfrom occurring.

[0105] Typically, although only preferably, the anti-shoplifting means 56 comprise, in this case, two laminar belts 57, 58a, opposite to each other, each one of which is made of a cut resistant material and provided at a first end 57a, 58athe one that remains free in the non-operational condition of the multilayer element 51with a coupling pin 59 that snaps into position in an engagement grip P, which is located inside the bulky body A.

[0106] The laminar belts 57, 58 protrude each one from the longer side edges 51b, 51c of the multilayer element 51, in such a way as they are easily insertable from opposite sides inside the bulky body A (generally inside the car cabin, as it has already been mentioned).

[0107] In practice, when the bulky body A is constituted by a car (as shown in FIG. 7), the laminar belts 57, 58 are inserted into the cabin of the car by going through the compartments V of the front doors R opposite to each other and are engaged with their own coupling pins 59 to the engagement grips P that are already available, and to which safety belts of the car A are normally attached and intended for the driver and the front passenger.

[0108] After being attached to the engagement grips P, the cut resistant laminar belts 57, 58 are still suitably pressed into position between the front door R seals and the frame E of the bodywork of the car A when the front doors R are closed: this guarantees a very reliable engagement system thanks to which theforced or accidentalremoval of the improved folding device 50 of the invention is really difficult and complicated even for criminals. In other variant embodiments of the improved folding device of the invention, which are not shown in the attached figures, anti-shoplifting means may comprise a number of laminar belts different from what has been indicated above, since this number may vary starting from one and up to, in general, the maximum value of four (as many as there are passenger doors in a car).

[0109] Moreover, if the improved folding device that is herein claimed is intended to cover a car, other embodiment solutions of the invention, that are again not shown in the enclosed drawings, may provide in that the anti-shoplifting means also include coupling ties, that are commonly freely associated to the longer lateral edges of the multilayer element and adapted to be tied around the front and/or rear door handles.

[0110] The number of such coupling ties will then depend on constructional choices and/or the needs of the market or the car, which the improved folding device of the invention for temporary covering a car, is intended for.

[0111] In further embodiments of the improved folding device of the invention for temporary covering a bulky body, such as a car, that are again not shown in the accompanying drawings, one or more of the multilayer covering sections of the multilayer element may comprise, on the upper face, a photovoltaic panel suitable for producing electrical energy to be stored in a battery associated with the car and intended for direct usewhile the multilayer element takes on its operational conditionto heat or cool the covered and protected bulky body; or it may be intended for indirect usewhile the multilayer element takes on the non-operational conditionto provide the car with the electric traction, lighting and/or the like.

[0112] From a practical and functional point of view, the improved folding device 1 of the invention initially takes on the non-application position, wherein the multilayer element 2 that characterises it, is in the non-operational condition, i.e. it is fully folded on to itself and creates the orderly and compact package 6, even better if it is inside the containment folding box integral to it: in this condition (see position S of FIG. 3), the improved folding device 1 of the invention suitable for car A of FIG. 4 takes up the least possible space and can be easily stored in the boot B of the car A, where it of a family, such as shopping bags.

[0113] In particular, in said non-operational condition, the multilayer element 2 suitable for car A of FIG. 4 (of the widely widespread type) has a height equal to 12 cm, a length equal to 68 70 cm and a width equal to 42 cm, with a total weight not exceeding 3 kg. What can be then clearly inferred is that the occupied space is the smallest possible occupied space, if not negligible, inside the storing area.

[0114] If necessary, when the motor vehicle A of FIG. 4 is parked outdoors, the user takes the improved folding device 1 of the invention out of the boot B and, if envisaged as in the case herein described, also out of the containment folding box and arranges it above the rear part S of the hood C of the car A, as symmetrically as possible to the main axis of development of the latter.

[0115] After that, by means of simple and quick unfolding manoeuvres, the user (by themselves and without any help from other people) first has the stacked multilayer covering sections 3 progressively rotate around the longitudinal lines K, going from the position S of FIG. 3 to the position P of FIG. 3, thus partially opening one first part of the multilayer element 2 of the improved folding device 1 of the invention.

[0116] Hereinafter, the user unfolds the multilayer covering sections 3 of the multilayer element 2, which is still mostly stacked, and has them rotate around the latitudinal lines W and towards the front part N of the car A, by going from position O of FIG. 3 to position F of FIG. 3 and thus covering the car hood C and the front window T of the car A.

[0117] Finally, the user rotates the remaining multilayer covering sections 3, those that are still overlapping onto each other, around other longitudinal lines K, parallel to those around which the multilayer covering sections 3 were initially rotated during the initial steps of the opening of the multilayer element 2 of the improved folding device 1 of the invention, by going from position E of FIG. 3 to position B of FIG. 3 and covering the side windows F of the car A.

[0118] The last manoeuvre that the user performs to fully open the multilayer element 2 of the improved folding device 1, until its maximum surface extension, can be inferred by observing positions B and A of FIG. 3 and consists in having the three multilayer covering sections 3 rotate around a latitudinal line W (parallel to the lines of the rotations that brought the multilayer element 2 from position O of FIG. 3 to position F of FIG. 3), but this time towards the rear end of the vehicle A: in such a way, the rear window L of the car A is covered and the application position of FIG. 4 of the improved covering device 1 of the invention is then obtained.

[0119] The progressive rotation of the multilayer covering sections 3 around the longitudinal lines K and the latitudinal lines W is obtained thanks to the longitudinal interstitial discharge recesses 5 generated by the application system of the locking or junction means 4; so, upon each rotation around said longitudinal lines K and latitudinal lines W, the involved multilayer covering sections 3, positioned along a given first longitudinal direction X or along a given second longitudinal direction Y, move integrally and simultaneously: the multilayer covering section 3 is grabbed and positioned by the user and it drags with it the other sections that are aligned to it.

[0120] The above described operating sequence for arranging the multilayer element 2 in its operational condition is performed in a reverse manner when the improved folding device 1 of the invention is no longer used: the movement sequence of the multilayer covering sections 3 is exactly the same as the one shown in FIG. 3 from position A (operational condition of the multilayer element 2) to position S (non-operational condition of the multilayer element 2).

[0121] As far as the operation of the improved folding device 50 of the invention is concerned, as shown in FIG. 6, its positioning on to the car A occurs in a manner completely equivalent to what was described for the improved folding device 1 of the invention.

[0122] The only difference concerns its application, which is more effective and stable, on to the motor vehicle A thanks to the anti-shoplifting means 56 that, when the coupling pins 59 have been inserted into the engagement grips P inside the cabin of car A and the front doors R of the car A are closed, allow the improved covering device 50 to be safely fixed on to the car A and to become burglar-proof.

[0123] On the basis of the above description, what is therefore clear is that the improved covering device to temporarily cover bulky and three-dimensional bodies, achieves the objects and obtains the above-mentioned advantages.

[0124] The improved folding device for temporarily covering bulky and three-dimensional bodies of the invention can be positioned according to the application conditions and can be folded when at rest or not in use in a very effective, quick and simple way if compared to the known devices equivalent to it.

[0125] The manoeuvre can be effectively performed, even if not by one person only, and not necessarily a skilled person or an adult, because of its low weight and easy operation that goes with the improved folding device used for temporarily covering the bulky and three-dimensional bodies of the invention.

[0126] At the end of the folding operation (or closure), the improved folding device for the temporary cover of bulky bodies of the invention takes on a definitely more orderly and compact position with respect to similar devices of the prior art, with all the correlated advantages, especially as for its storage.

[0127] It should be noted that many different versions of the improved folding device according to the present invention used for covering bulky bodies, are produced having different sizes, and this due to the type and size of the bulky body to be covered and protected for which the device is intended.

[0128] In this regard, in further constructional solutions that are not shown, the improved folding device of the invention for covering bulky bodies may be intended to cover and protect the entire surface of the bulky body, when the multilayer element that characterises it, takes on its operational condition, for example the whole body of a car. In addition, the improved folding device of the invention used for temporarily covering the bulky bodies may include advertising signs or messages, positioned onto the upper surface of one or more of the multilayer covering sections of the multilayer element, in particular on the upper face of the upper layer made of water repellent reflective fabric, thus making it interesting for commercial companies too.

[0129] Finally, what is clear is that numerous other variants may be made to the improved folding device for said covering bulky bodies, without departing from the innovative principles inherent in the invention, just as it is clear that in the practical implementation of the invention, materials, shapes and sizes of the details illustrated may be different according to the requirements and may be substituted with other technically equivalent elements.
