DESCRIPTION

Folding structure with rapid deployment and folding

The present invention refers to a folding structure designed to move from an unfolded position to a folded position, as well as to carry out the reverse process, and which has telescopic uprights that each have at least one lower element that is it slides in relation to an upper element connected to said structure, and that supports a set of adjacent prismatic drawers, whose walls are formed by crossbars articulated in scissors.

The present invention belongs to the field of removable or collapsible structures intended to serve as a refuge.

A shelter of this type is generally formed by a metal structure covered, at least by the top, by a covering element, giving rise to a roof. The most common arrangement of this shelter, in an unfolded position, simulates the appearance of a store, showing the shape of a cube on which a pyramid stands.

This type of shelter is intended for a specific use, such as stand or similar, for a specific duration, leading to quick and easy assembly and disassembly. For this reason, the existing shelters have a folding design, from a folded configuration, for transport and storage, to a deployed position, or vice versa. The possibility of folding and unfolding the shelter greatly facilitates its assembly, compared to those shelters that have a structure formed by stringers, rods or removable bars and joined together by fasteners.

A folding shelter comprises a structure normally formed by metal stringers, for example, in the form of profiles in aluminum or aluminum derivatives, or other types of composite materials, such as fiberglass, carbon or the like. These stringers are articulated between them in such a way that they allow the passage of said shelter from a folded position to an unfolded arrangement, and vice versa.

In addition, the cover element is subject to said structure so that the folding or unfolding of the shelter does not need to remove said cover element. To achieve this, the latter is designed as a canopy, made of textile, plastic or similar, flexible and waterproof, fixed to said structure.

However, known folding shelters are limited in terms of size due to the transport of the structure and the weight supported by the articulated stringers, as well as the total mass of the structure. Known shelters generally have a maximum surface area of 24 m2. For larger surfaces, it is necessary to use classic removable shelters.

The implementation of large shelters, of the order of 5 x 5 meters or greater, offers undeniable commercial advantages to its user: large surface and volume capacity, clean appearance and excellent visibility. This last factor is particularly important for the participation in exhibitions, where each exhibitor wishes to separate themselves from their neighbors, specifically in the volume and height of their facilities.

In order to allow a remarkable extension in altitude of a refuge of this type, it is convenient to conceive the shelters with a high structure that entails legs or uprights of great size, or at least that it has an area higher than the rest, which entails resorting to one or several mastiles.

The basic service limitations, taking into account the regulations of many countries, refer to:

- Wind resistance.

- Resistance to a large volume of rain or snow, being able to accumulate on the coverage of said shelter.

These rules also impose the evacuation of the public in case of exceeding the wind speed thresholds or static load. In addition, it will be of interest to the user in a situation such as reducing wind resistance, unloading shelter cover, as well as retracting or disassembling it quickly if conditions become extreme.

Such a structure, of great surface and height, will necessarily be heavier and more complex than a structure conceived only to allow, at ground level, the passage of the public, and where the dimensions conform to the height standards for the circulation of people.

In particular, the mass of a large shelter that covers, for example, an area of 5 x 5 m represents, even using light materials, a mass considerably greater than 100 kg, which cannot be easily handled by a single person.

To this end, in the application WO 01/27417 a folding structure is presented consisting of telescopic uprights that each have at least one lower element that slides in relation to an upper element, incorporating deployment and folding elements. in said telescopic uprights. These uprights support a set of adjacent prismatic drawers between them. The walls of said drawers are formed by crossbars of scissors articulated stringers, suitable to move from a deployed position to a folded and vice versa.

Under Article 54 (3) of the CBE, application WO 2007/057604 also discloses a similar folding structure. In this case, the upper element of the telescopic uprights entails, on all or part of its length, grating means constituted by a rail through which a carriage slides. The articulated ends of the stringers that the structure implies are mounted on these cars.

The inconvenience due to the mass that a large structure already entails is increased by its height development.

The present invention aims to alleviate the drawbacks of the state of the art with the proposition of a collapsible shelter structure, suitable for moving from a deployed position to a retracted (and on the contrary), which has telescopic uprights that contain each, at least, a lower element that slides in relation to an upper element attached to said structure, and which support a set of adjacent prismatic drawers, whose walls are formed by crossbars articulated in scissors. Said uprights include deployment and retracting means, incorporated in said telescopic uprights, and the upper elements comprise, in all or part of their length, grating means constituted by a rail designed to cooperate with the rolling means formed by a carriage that it slides through the interior of said rail, and on which the articulated ends of the stringers containing said structure are placed, whose deployment and folding means are formed by gas springs.

According to one of the features of the present invention, said lower element slides inside the upper element.

The invention is also designed to allow its easy implementation by a small staff, even by a single person.

An advantage of the present invention lies in the fact that it provides, in addition to an area of 24 m2, an alternative to the use of removable structures.

The present invention refers to a folding structure 1, which allows to move from a stowed position of storage or transport, to an unfolded position, or the other way around, and is intended to constitute a shelter 2 in an unfolded position. The displayed position is shown in figure 1.

Said shelter 2 has cover means 3 attached to said structure 1 so that they fold along said structure when shelter 2 is retracted. Said cover means 3 can advantageously be presented in the form of a single or double cover awning, made of a plastic compound or any other material. Said awning is subjected to lateral tension due to the deployment of the structure 1. In addition, a central mast 4 stresses the vertical of the awning. Said mast can be placed on a cam, so that it can be raised or lowered with the help of a crank, not shown. In tension, the covering means 3 form a slightly pyramidal roof. Said roof may be crowned with a lid 5 attached to the upper end of said mast 4.

The structure 1 comprises stringers 6 articulated between them so that they form a kind of net that allows folding and unfolding. Said stringers 6 move simulating an accordion on scissor type joints 30 to allow their separation and approach, and the extension or contraction of said stringers 6, which is carried out transversely in a horizontal plane.

The skeleton of the structure 1, constituted by the stringers 6, has been conceived in order to provide, by its rigidity, a good wind resistance. In fact, wind resistance is the biggest obstacle when making large shelters, whether deployable or not.

In this way, the skeleton of the structure is designed as a set of drawers 20 adjacent to each other, whose walls are constituted by said stringers 6 articulated in scissors.

As can be seen in Figure 2, the stringers 6 constitute, joined and modulated by joints 30, the almost flat sides 22 of said drawers 20, the latter represented with a dotted line.

The stringers 6 define among them deformable drawers 20, juxtaposed to each other, which necessarily lose their shape at the same time.

Preferably and as can be seen in Figure 1 and 2, the stringers 6 on each side 22 are assembled forming crossheads 21, in the form of complete rhombuses within the structure 1, and rhombus means at the edges of said structure.

The structure 1 preferably has a construction symmetry in reference to at least one vertical plane passing through the highest point, which corresponds to a mast 4.

In particular applications, such as those shown in Figure 1 or 3, in cases of polygon planes with a number of even sides, parallel and equal two to two, the structure 1 is symmetrical in terms of a vertical axis passing through its highest point, coinciding with the axis of its mast 4.

In the case of structures with more complex forms, mainly rectangular, structure 1 is symmetrical in terms of a plane of symmetry that passes through several high points, of equal or different altitude.

The stringers 6 are arranged to remain, along the maneuver, in planes parallel to the axis of symmetry that exists, or parallel to a vertical axis of the plane of symmetry.

In a desirable application and in the case of a polygonal plane structure, each side of the polygon supports an odd number of drawers 20. Thus, in particular in the case of a structure with a vertical symmetry axis, said axis is framed in the central part of the structure by at least one drawer 20. Said arrangement allows, principally, to conceive oblique windproof means, taking support on said drawer 20 located on the axis, to reinforce the mast 4 that passes along the axis of simetna.

In case of intense wind, the tangential forces to the horizontal component supported by the upper part of the covering means 3 are assumed by the mast 4. A structure of this type, encased and centered

around a mast 4, it allows to show an important resistance to horizontal forces. It also allows to ensure a good maintenance of the geometry of the shelter structure 1 in its entirety.

The central drawer 20, thus constituted and according to the number of drawers 20 that have support on each side of the poKgon, is drawn in the homotetic structures of a larger size.

The structure 1 has uprights 8 and each of which has telescopic support means 7 constituted, at least, by a lower part 9 and an upper part 10.

The invention also contemplates the easy implementation by a reduced number of personnel, even by a single person, with the help of a lifting, mounting, lowering and dismantling device of structure 1.

For this purpose, the uprights 8 are well equipped with at least two elements, mainly the lower element 9 and the upper element 10, as well as deployment means 40, such as those shown in Figure 4.

Said deployment means 40 allow to correctly perform both the deployment maneuver proper of each upright 8, moving the lower part 9 away from the upper part 10, thus helping to raise the structure 1, such as the reverse folding maneuver, which consists in the approach of both parts, in the course of which the deployment means 40 prevent the structure 1 from falling, holding it by a controlled descent. These deployment means 40 may be formed mainly by pneumatic, hydraulic, electromechanical or similar elevators.

Preferably but not limited to, the deployment means 40 are formed by one or more pneumatic elevators, gas springs 41, light and autonomous, which are characterized by not needing a baton or the like. In addition, they may consist of a series of several small gas springs 41, of short stroke, in order to be compatible with the reduced size required in the retracted position. The straps 42 allow, if necessary, to adjust the races of said elevators 41.

For example, by equipping with gas springs 41 the four uprights of a 5 x 5 meter square 2 shelter structure that represents, together with the canopy-shaped covering means 3, a mass of about 130 kg, makes it possible the assembly by a small team, or by a single person, without too much physical effort. On the contrary, any risk of jamming and coffee is avoided during the maneuver.

It is preferred that the rail assembly is made of plastic on aluminum alloy, in order to reduce friction to the maximum.

These deployment means 40 allow to guarantee, in addition to the lifting and lowering functions of the structure 1, the anti-return function by keeping them in position, the balance between the different uprights 8 being appreciable on their irregularity.

It should also be taken into account that, in times of strong wind, it is possible to bring the deployed structure corresponding to the configuration of Figure 5 to the ground, to reduce wind resistance, with the help of the deployment means 40, visible in the figure 6.

In order to facilitate an eventual transport in climatic situations of great violence, the structure also contains means of movement on the ground by means of sliding or rolling.

The use of deployment means 40 makes possible, in turn, the design of shelter structures containing uprights 8 composed of a lower element 9 and an upper element 10, as well as intermediate elements.

That is why it is possible to manufacture shelters in which the uprights 8 are high.

For large structures, one or more secondary means of deployment 25 are used, as shown in Figure 2, located inside the articulated cross-members 21, which together form the different stringers 6 on the side of the drawers 20 that make up the structure.

These stringers form a set of rhombuses or rhombus means. The deployment aid is carried out, either by implanting the secondary means of deployment 25 in the diagonals of the diamonds whose length is increasing during the deployment, or by implanting them in the diagonals where the length is decreasing during the process.

This second configuration of the example of figure 1 is preferred, as it appears in figure 2, since, in this case, said secondary means of deployment 25 are parallel to the uprights 8, which entails a much easier implantation in a structure folding.

These secondary means of deployment 25 again have the function of reinforcing the structure in view of possible vertical forces, such as the load that snow can exert on the covering means 3. They maintain the diagonal separation and allow to limit the deformation of the structure 1 subjected to said load. Favorably, the secondary deployment means 25 are performed analogously to the deployment means 40, and preferably by gas springs.

Folding structures 1 according to the present invention advantageously involve first closing / opening means 80 in a retracted position, associated with the first complementary means 81.

In the uprights 8 of the structure, the upper element 10 comprises, in a preferable embodiment, over all or part of its length, rail-shaped means 13 suitable for cooperating with the articulated rolling means next to the structure one.

These rolling means have a carriage 12 that slides inside the rail 13. Said carriage 12 supports the stringers 6 adjacent to said uprights 8 articulated at its ends for the deployment of the structure 1.

The rail 13 is also designed to be able to support the limitations of transport of fluids, energy and communication media, in the form of nestable kits containing self-locking uprights 13.

In particular, the anchoring means to the power supply means and / or the communication means can be constituted in the form of blocks of electrical, optical and other sockets, advantageously integrated in the uprights 8.

As shown in Figure 7, the first closing / opening means 80 are formed, in a preferable application, by a mechanism 82 that comprises a carriage 12 that slides inside or outside an upright 8.

The complementary means 81 are formed by a cavity 83 located in the same upright 8 and suitable for housing said mechanism 82. The mechanism 82 is equipped with elastic return means, in the form of a spring 86, which tends to push said mechanism into a closing position in said cavity 83, and a pressing means 88, in the form of a button, which allow the mechanism 82 of the cavity 83 to be released, for the opening maneuver.

Obviously, the reverse configuration is perfectly imaginable. The means 80 and 81 may, in turn, be formed by a hook that cooperates with a lock, in the form of a pin or shaft, or in a redproc manner.

The folding structures according to the present invention show, advantageously, a second closing or opening means 90 in the deployed position, associated with a second complementary means 91. Its configuration can be analogous to that of the means 80 and 81 described above. The complete deployment of the structure corresponds to the achievement, by the carriage 12 that slides in or on the stud 8, from its position further from the ground. To facilitate the closing or opening maneuver without the user having to resort to means such as a stool, ladder or the like, a desirable embodiment, such as that shown in Figure 8, consists of closing / opening means 90 in the form of handle 92. Said handle 92 is articulated on an axis 94 in an intermediate position that is placed next to the stud 8 and contains, at a first end 95, a hook 96 designed to cooperate with the complementary means 91, such as a bolt or shaft containing the carriage 12, for example, on a tread 93. The elastic return means 99, like a spring, tend to cooperate the hook 96 with the axis 91. The handle 92 has, at a second end 97, a handle of manipulation 98 whose actuation allows to cancel the operation of the return means 99 and release the hook 96 of the axis 91.

Other optional locking means, as shown in Figure 5, are formed by one or more tension cables 45 that connect, between them, at least two uprights 8 at the top of the unfolded structure, by means of pulleys or shaft shafts. or the like, and which are suitable to be under tension, once the structure 1 is fully deployed, for example, with the help of an eccentric handle, or the like.

In a desirable application, the displacement of said tension cables 45 is carried out inside the components of the structure 1, in particular in the stringers 6 and the upper parts 10 of the uprights 8. The latter are usually equipped with grating means. and return for said tension cables 45.

As can be seen in Figure 2, other tension cables 23 are also used to reinforce structure 1, to complete the sides 22 of the drawers 20 that form the structure 1: said sides 22 of the drawers are formed by the cross members 21, in Shape of rhombuses or juxtaposed rhombus means. The tension cables 23 are

therefore, to complete the virtual structure of the sides 22 of the drawers 20, in the form of straight lines almost parallel to the floor in the joints 30, of a higher level 23A and / or lower 23B, of the sides 22 of the drawers 20.

In order to improve the geometry of the deployed structure 1, especially in regions subject to high wind, the bases 11 and / or the lower parts 9 of the uprights 8 are advantageously arranged to accommodate the fixing of the straps 70, mainly telescopes, which ensure a complementary tension, as well as a perfect parallelism of the uprights 8, as shown in Figure 5.

It will be understood that these braces 70 are designed to work both in traction and in compression buckling. Said braces 70 thus improve the strength of the structure in adverse weather conditions, heavy snowfall or hurricane winds parallel to the ground.

These braces 70, preferably arranged near the ground, can be equipped, mainly, with means for receiving curtains or closures, such as the lower hooks or the tensioners, or have some type of thresholds.

This last equipment is quite interesting when the shelter is destined to have a floor, which is defined and immobilized in turn with the tensioners 70.

In the case of building complex structures resulting from the juxtaposition of several shelters according to the present invention, the union is carried out easily by means of fasteners, such as shackles on the high parts, or beta pins on the bases 11 down.

In a simplified embodiment, as shown in FIG. 9, the locking means are formed by a coupling member 100, articulated around an upper joint 101 of at least one articulated crosshead 21.

Said hooking member 100 has in its lower part a hook 103 arranged to cooperate with a bolt 102, or the like, which has a lower joint 102 located in the vertical of said upper joint 101.

This hook member 100, due to gravity, remains almost parallel to the uprights 8 during the deployment of the structure and the elevation of the lower joints 102.

That hook 103 or that pin 104 preferably comprises means of immobilization in relative position of one with reference to the other, either by deformation, by means of elastic return such as a spring or by an annexed means of preservation of position.

Thus, said coupling stringers 100 allow, in a simple and efficient way, to reinforce the rigidity of the structure by simply actuating the hooks 103 with the bolts 104, in particular in the case of adverse weather conditions. They maintain a diagonal separation and allow to limit the deformation of the structure under the load.

In order to contribute to the reinforcement of the folding structure 1 and in order to enable good safety conditions for the equipment of a shelter, a clamp 60 designed to be fixed at the edge of the wall has been designed, as shown in Figure 12. unfolded structure, on the end of each stringer 6 that holds the awning 3, in a clamp or clamping screw.

Said clamp 60, which can contain a collapsible pin, has a hook-shaped bottom for receiving and fixing at least one horizontal crossbar 61. Said horizontal crossbar 61 appears suspended and preferably contains a groove 62 in the bottom in the form of a rail for the curtain fasteners with casters or similar.

In one of the variants, the horizontal sleepers 61 are designed to be fastened, after the deployment of the folding structure 1, in the upper parts 10 of the uprights 8, mainly in cooperation with one or more cavities 131 containing said upper parts 10 It is preferred that a horizontal sleeper 61 of these be articulated to have a reduced size when folded, compatible with that of the folded structure 1 by itself. At least, it has a hinge 601 which also functions as an extension stop in the unfolded state, as shown in Figure 19. The horizontal crossbar 61 has at least one groove and a recess for receiving the lateral awnings. , intended to constitute the walls of the folding structure 1, and of its suspension wheels.

In another version, structure 1 is designed to withstand strong weather conditions; for example, near the sea or in the mountains.

The use of horizontal sleepers 61 is considered very appropriate to provide greater rigidity to the structure.

To achieve even greater firmness, the structure 1 incorporates, at least, a reinforcement 130 designed to cooperate with the upper part 10 of the upright 8 and the adjacent horizontal crossbar 61, in order to provide rigidity to its joint once the structure 1 is deployed, the horizontal sleepers 61 mounted, and after the immobilization of said reinforcement 130 by blocking means 133.

As shown in Figure 14, the upper part 10 of the stud 8 comprises a cavity 131 suitable for receiving the reinforcement 130 by sliding. Said reinforcement is thus enclosed in a horizontal sleeper 61 at the height of the cavity 132 it presents. The reinforcement 130 moves manually, like a latch, through the manipulation means who, preferably, will also constitute the blocking means 133. In the example of the embodiment visible in the figures, the reinforcement 130 contains a protruding mechanism 137 through the slot 136 arranged in the horizontal crossbar 61. Said mechanism 137 supports the axis 135 of an eccentric lever 134, used for unlocking, shifting and locking the reinforcement 130 in relation to the horizontal crossbar 61. Positively , each upright 8 comprises two cavities 131 to cooperate with two adjacent horizontal sleepers 61.

Analogously, structure 1 incorporates at least one reinforcement 130 capable of cooperating with two adjacent sections 602 and 603 of a horizontal crossbar 61, in order to provide firmness to its joint, once said crosspiece 61 is deployed and in support on the hinge 601, and after the immobilization of said reinforcement 130 by blocking means 133. The same type of reinforcement 130 is used, as shown in Figure 15, to reinforce the union of two adjacent sections 602 and 603 of a horizontal crossbar 61 after full deployment of the latter. The reinforcement 130 slides in the cavities 132 in both adjacent sections 602 and 603 and joins them inside. The reinforcement 130 is immobilized by the blocking means 133 of the aforementioned type. It is preferred that all joints between sections 602 and 603 entail such reinforcement 130.

In a desired version, the cross-members 21 of the folding structure 1 contain said clamps 60 for the management of the covering means 3, mainly in the form of a canopy, and for the fixation of a horizontal crossbar 61. In the latter case, the clamp 60 has a wall lamp capable of supporting the covering means 3 and keeping them far enough away from the mechanical organs during the deployment and folding maneuvers to avoid any type of binding.

Folding structures according to the present invention should be able to be deployed on all types of terrain, mainly rugged terrain, so they should be able to regulate their position with respect to the ground.

For this purpose, the clamp 60, which is mounted together with the folding structure 1, will also be together with, according to the pivoting joint, a connecting piece 140.

Said union piece 140 is designed to reinforce on the outside the union of two sections 602, 603 of a horizontal crossbar 61 adjacent to each other, as well as to be fixed through the immobilization means 141 fast, such as quarter turn closures or similar. The connecting piece 140 preferably has a U-shaped profile, which overlaps adjacent sections 602 and 603.

According to each case, the connecting piece 140 may be permanently left on the folding structure 1, or placed on the clamp 60 after the deployment of the structure 1.

The pivoting joint between the clamp 60 and the connecting piece 140 is carried out on a pivot 142 containing the latter. It is understood, therefore, that it will be easy, once the previous assembly of the corresponding horizontal sleeper 61 has been carried out, to regulate at will the angular position thereof, to the extent that the cavities 131 of the upper parts 10 of the uprights 8 have designed to allow a displacement that allows the regulation prior to the immobilization.

Said clamp device 60 that collects a horizontal sleeper 61 is also used to create mid-height separations, "American bar" type, in the shelter penimeter or to divide the latter.

The covering means or awnings 3 of the adjacent structures in a composition of several shelters appear connected in its penimeter by means of drainage, such as a conical gutter 50, preferably connected to the awnings 3 of the respective shelters by means of joining systems made Velcro, like the one shown in Figure 10. In Figure 11, said conical gutter 50 allows the rainwater to be evacuated to a collection means 51, which can be located at a point of confluence of several annexed shelters, by means of a flexible tubena or ngida under the shelter floor or on the support floor.

Preferably, the arrangement of the uprights 8 and the bases 11 is designed to allow the square juxtaposition of four uprights 8 of four different shelters and constitute among them a suitable channel to receive

the collection medium 51 in the upper part and the lower tube.

In addition, it is common knowledge that the inclement weather causes numerous problems of use for shelters with flexible awning, both due to the force of the wind and the accumulation of rainwater, creating water pockets on the edge of the peripheral frame where the awning is fixed.

This fact is usually detrimental to the fixation of accessories in good condition, in addition to safety when it comes to electrical accessories.

The horizontal cross member 61 also includes a watertight compartment 63 designed to house electrical circuits or the like.

By way of the foregoing, the electrical supply of a shelter according to the present invention, particularly advantageously, is guaranteed by means of photovoltaic cells located in the covering means 3 or in the penimeter bands of the latter, as well as batting .

Such an arrangement with suspended accessories prevents the appearance of thresholds with water bags.

The fastening of the awning 3 at the height of the angles can be carried out with the help of a mechanical shackle for hooking the winds / cables.

At ground level, it is preferred that the bases 11 be equipped with holes to house the picks, in the case of the installation of the structure on a single piece.

Mast 4 can have different configurations, solid or perforated, in order to accommodate or operate lightning rod. In a particular application, it is designed to contain an anemometer, so that the dynamic base pressure due to wind can be evaluated.

Thus, the structure 1 according to the present invention is provided with different physical magnitude sensors in the stringers 6 and / or joints 30, in particular of extensometers that allow the evaluation of the overload due to snow.

The implantation of a treatment unit allows the collection of values of said physical quantities, their comparison with the setpoints and the creation of signals such as, for example, to activate an evacuation alarm if the weather conditions force the user to start the evacuation , according to national regulations, or if the dynamic base pressure and snow overload are higher than the thresholds defined by the regulations.

To improve the visibility of the structure 1, especially in cases of inclement weather, one of the embodiments contains, at least in an upright 8, reception means 108 for signaling means 109, mainly in the form of a slot 110 to accommodate a light garland 120, LED wire or the like, thus constituting the means of signaling 109.

Preferably, and as shown in Figure 16, the lower part 9 and the upper part 10 of each upright 8 each have a groove 110 in the form of a duct, respectively 111 and 112, designed to house, either a single garland 120 , or garlands 121 and 122 in conduits 111 and 112 respectively. The profile of each conduit 111 and 112 is circular, so that it can accommodate a garland 120, 121 or 122 of round section, and secant with the outer profile of the profiled in question, so that the signaling means 109 are visible in the minus a part of the penimeter.

As shown in Figure 18, garlands 121 and 122 are designed to cooperate when the bottom

9 and the top 10 of the stud 8 are completely separated, with a joint that allows electrical continuity.

The groove 110 is also designed to house a cord 115 that carries with it a canopy, a curtain or any other means of lateral concealment 116 of the folding structure. Ducts 111 and 112 appear aligned. As it appears in figure 17, the conduit 111 of the lower part 9 preferably has, at least at its upper end, a light 113 which allows the cord to be strung frontally inside the profiling. The conduit 112 of the upper part 10 carries, at least at its lower end, a light 114 similar to the light 113. Other similar lights may be arranged at other ends of the lower part 9 or the upper part

10 of an upright 8. In this way, it is very simple to position and fix any lateral concealment means 116 in the uprights 8 of the collapsible structure 1. A lateral concealment means 116 can also appear fixed to the cover means 3, in a horizontal band, through fastening means suitable for cooperating with complementary fastening means, such as velcro or the like. The structure thus equipped has, in addition, a perfect seal against the inclement weather and its thermal equilibrium can be guaranteed with

more easily

The signaling means 109 are fed from January through autonomous feeding means (photovoltaic or wind, for example), causing the covering means to be made of materials 5 suitable for said use. In addition, the power supply of the LED garlands, due to their low consumption, can be carried out by means of a small baton or a battery of about 12V, sufficient to feed a garland of LEDs of 400 m for 48 hours.

On the other hand, said signaling means 109 may be integrated in the covering means 3 or in the 10 lateral concealment means 116.

In the case where the structure is equipped with autonomous means of power supply, it can be used as a greenhouse or plant for growing vegetables.
