Description

The present invention relates to telescopic shelters such as shelters

  telescopic pool and especially telescopic shelters with multiple ride height. There are many mobile or partially mobile shelters to protect particular locations from external hazards. In particular, mobile swimming pool shelters are adapted to limit access to swimming pools for safety reasons, to protect them against certain elements such as leaves and objects that may be deposited in swimming pools, particularly by wind, and improve the warming of the water or limit heat loss.

  Among mobile or partially mobile shelters, telescopic shelters, also called sliding, using the trundle principle, have the advantage of being able to discover almost the entire basin since in the folded position, the surface of the shelter on the ground is globally limited to the width of a single element.

  These shelters are characterized by the fact that each roof element has a rope, corresponding to the distance between the two longitudinal edges resting on the ground and which connect the arches, greater than that of the roof element which precedes it, so that in the folded position, all the modules retract under each other.

  This principle, however, has disadvantages among which a significant footprint because each module is necessarily wider than the previous one. This results in a high overall weight. In addition, all the longitudinal edges of the shelter being placed on the same plane, all the modules must be placed on the terrace if the coping and the terrace are not at the same level (the width of the coping is insufficient to receive all the elements). Finally, the heavy weight of the modules makes it difficult to manipulate the shelter, especially when it is necessary to move the element to move. To overcome this and avoid crabbing modules, some manufacturers opt for a rail guidance of all their elements. Alternatively, there are low shelters with articulated roof elements consisting of two sections of modules, the large part of which is generally fixed and under which the small can roll, each section consisting of several elements of identical strings interconnected. Such shelters have a reduced footprint and offer the possibility of arranging the shelter on the lip, since the standard width thereof allows the juxtaposition of two sections of different ropes. For example, the patent application FR 2 825 738 describes a pool roof for low shelters consisting of roof elements juxtaposed in the direction of the length of the pool and at least one of the two longitudinal edges is articulated relative to the ledge of support of the basin of the swimming pool. The roof is constituted, on at least a portion of its length, juxtaposed roof elements whose distance that delimits the outer rope of the two longitudinal edges resting on the support rim of the basin and that connect the two arches is less than the distance defined by the inner rope of the two longitudinal edges resting on the support rim of the basin and connected by the two arches of the elements juxtaposed with the other portion of the roof to allow the interlocking of the first portion of the small elements in the second portion of large elements and partially discover the pool on a length corresponding to the displacement of the movable portion of elements.

  However, such shelters have certain disadvantages. In particular, in the folded position, the shelter only discovers a limited portion of the basin, less than or equal to half of its length. In addition, laying on a curb is only possible for basins of pure rectangular shape. These shelters are particularly unsuitable for rectangular basins equipped with an end staircase or require the installation of complementary devices to close the part comprising the staircase. In addition, when these shelters are mounted on a lip, they generally use guide rollers, without rail, to avoid the inconvenience caused by the presence of a rail on the lip. The handling of these shelters is therefore uncomfortable. These shelters have a vertical facade at each end. These facades, also called cheeks, gables, pediments or half-moons, allow to close the shelter and to condemn the access to the basin. In the family of telescopic shelters, the characteristics of these facades are an important element. Indeed, the facade may cause problems during the setting in motion of the end module, because it can abut on the bottom of the coping when the shelter is placed on terrace or on the nose of the lip when the The shelter is placed on a coping. Only configurations with flat edges and terrace at the same level can prevent the friction against the ground of the lower part of the facade. The existing solutions before moving the module are as follows, completely remove the front panel to maneuver the shelter, the facade may consist of a single part or more, retract the front by tilting under the module, enhance the part bottom of the cheek to go over the coping and fill the day with a very high bib joint or hide the front by tilting by its half. However, each of these solutions have disadvantages.

  In particular, these solutions are tedious, cause weaknesses in the structure of the shelter, are unsightly and / or lack ergonomics for the handling of the shelter. The invention solves at least one of the problems discussed above.

  The invention thus relates to an angle element for telescopic mobile shelter structure formed of at least two modules, said modules being aligned along a longitudinal axis, each module comprising at least one portion adapted to be placed on the ground said at least two modules being fixed to one another by junction elements with at least one degree of freedom allowing one of said modules to have a substantially horizontal translational movement, along the longitudinal axis of said at least two modules, relative to the second of said at least two modules, this corner element being characterized in that it comprises a first visible part, a second part adapted to receive at least partially a bank and a third part adapted to at least partially receiving a bow, said first portion comprising a cavity open on the side, formed in a side adjacent to said second portion, said cavity being adapted for receiving a guide element of the trolley guiding element type or for receiving a joining element, said first part also comprising an open slideway, parallel to said bank, formed on the side opposite to said cavity and said second part comprising a cavity open down adapted to receive a wheel whose axis of rotation is perpendicular to said bank. The corner element according to the invention makes it possible to reduce the number of different parts necessary for mounting a telescopic shelter while offering numerous mounting possibilities. According to a particular embodiment, the corner element further comprises a through hole between said cavity and said side of said first part comprising said slideway, said through hole being adapted to fix said junction element in an adjustable position. It is thus possible to easily adjust the position of the connecting element according to the gap between two neighboring modules.

  Still according to a particular embodiment, the corner element further comprises a through hole between said cavity and the side of said first portion opposite said second portion, said through hole being adapted to receive a key that can be maintained by said junction element, said key being adapted to assemble two corner elements of the type claimed. This embodiment makes it possible to rigidly assemble two modules one to the other. The corner element furthermore advantageously comprises at least one blind or penetrating hole formed on the side of said first part opposite said second part, said at least one hole being adapted to receive a connecting element of a guide element. of the roller guide element type. The adaptation of a guide element of the roller guide element type reduces friction during relative movements of one module relative to another and thus to facilitate the operation of the shelter. Said roller guide element preferably comprising a movable portion adapted, in a first position, to fix said corner element to the ground or to a rail to limit the movements of the module on which it is mounted.

  Still according to a particular embodiment, the corner element further comprises a vertical through hole formed in said first and third parts adapted to evacuate condensation water and / or runoff and avoid problems such as problems. related to frost. Still according to a particular embodiment, the corner element comprises a through hole in said second portion, perpendicular to said bank, adapted to receive the rotation shaft of said wheel, this hole being advantageously open downwards to simplify disassembly of said rotation shaft of said wheel. The maintenance of the shelter is thus facilitated as well as the change of type of roulette used.

  Still according to a particular embodiment, the corner element further comprises connecting means in its lower part, said connecting means being adapted to receive a wedging element and / or anchoring to anchor the shelter to ground and prevent any inadvertent movement due to extreme loading conditions of the shelter. The wedging element has the function of wedging the shelter and thus relieve the pressure exerted on the rollers in order to avoid in particular the deformation of the rollers. The invention also relates to a telescopic shelter comprising at least one corner element as described above. Other advantages, aims and features of the present invention will become apparent from the detailed description which follows, given by way of non-limiting example, with reference to the accompanying drawings, in which: FIG. 1 schematically represents a swimming pool that can be protected by the shelter according to the invention; FIG. 2, comprising FIGS. 2a and 2b, illustrates an exemplary shelter according to the invention; - Figure 3 shows a sectional view of the shelter and the pool along a transverse axis; - Figure 4 is an aerial view of the pool comprising guide rails arranged on the terrace, on either side of the pool, along a longitudinal axis, closer to the edge; FIG. 5, comprising FIGS. 5a to 5f, illustrates an example of storage and deployment of the modules forming the shelter; FIG. 6, comprising FIGS. 6a, 6b and 6c, shows a first example of a partially liftable facade of the shelter; FIG. 7, comprising FIGS. 7a, 7b and 7c, shows a first example of a partially liftable facade of the shelter; Figure 8 illustrates a portion of a module comprising profiles, corner pieces and surface elements; FIG. 9 illustrates an example of an angle element intended to hold the elements of the lower part of the shelter; Figure 10, including Figures 10a and 10b, illustrates two examples of adaptation devices for the corner element shown in Figure 8; - Figure 11 illustrates a corner element, fitted on a profile, on which is fixed a roller guide device; - Figure 12 illustrates the mounting of corner elements on two profiles allowing a translation movement of the profiles relative to each other along their longitudinal axis; FIG. 13, comprising FIGS. 13a and 13b, represents an example of a fixing mechanism for anchoring the shelter to the ground; and FIG. 14 shows a condensate drainage system integrated into the shelter. FIG. 1 schematically represents a swimming pool 100 that can be protected by the shelter according to the invention. As illustrated, the pool 100 comprises a basin 105 which, according to this example, has a rectangular shape. The round of the pool consists of a lip 110 separating the basin 105 from a terrace 115 formed around the pool. The edge is here the stone zone about thirty or thirty-five centimeters wide which surrounds the basin resting on the frame of the swimming pool and the terrace is the peripheral zone located beyond the coping. The height of the coping is here greater than that of the terrace thus allowing objects located on the terrace can not slide in the basin. This type of coping is also called overflowing margins. The pool includes a Roman staircase 120 formed at the end of the pool. FIG. 2, comprising FIGS. 2a and 2b, illustrates an exemplary shelter according to the invention. Figure 2a shows a perspective view of the shelter covering the pool of Figure 1, while Figure 2b shows a side view along the longitudinal axis of the pool. The shelter 200 here consists of three modules 205-1, 205-2 and 205-3, each module being composed of two roofs juxtaposed and interconnected. The module 205-1 thus includes the roofs 210-11 and 210-12. Similarly, the module 205-2 includes the roofs 210-21 and 210-22. The dimensions of the modules 205-1, 205-2 and 205-3 are such that the module 205-1 can be housed under the module 205-2 which can itself be housed under the module 205-3. Thus, the 205-1 and 205-2 modules can be stored under module 205-3 and cover only about one third of the pool. When deployed, the modules 205-1, 205-2 and 2053 cover the entire pool. Each shelter according to the invention is preferably composed of at least three modules corresponding to different types of roofs allowing the interlocking of the modules one under the other according to the trundle principle. The general principle is that the different modules composing the shelter move closer to the bathing basin to reduce the overall size. For this, two different modules are advantageously mounted on the upper part of the lip and another module is mounted on the terrace. Thus, the shelter according to the invention combines in particular the advantages of limited space in width and rectangular pool cover with overhanging curbs and end stairs. The principle of opening the shelter on a rectangular type basin with Romanesque staircase at the end is as follows. The largest module, preferably mounted on rails, is advantageously positioned on the side of the stairs to compensate for the height difference between the coping and the terrace. The opening is thus preferably from the largest module to the smallest module. This principle also allows to discover both ends of the basin. Figure 3 shows a sectional view of the shelter and the pool along a transverse axis. As illustrated, the modules 205-1 and 205-2 are supported on the lip 110 while the module 205-3 is supported on the terrace 115, closest to the lip. According to a particular embodiment, the modules 205-1 and 205-2 are mounted on single rollers 310-1 and 310-2, respectively, while the module 205-3 is mounted on rollers 300, possibly comprising a sheave. adapted to cooperate with a rail 305 whose shape is adapted to control the movement of the rollers 300. The rail 305 may have, for example, a central protrusion cooperating with a wheel of the wheel 300. Alternatively, the rail 305 may have two protuberances located on either side of the wheel 300, as shown.

  According to yet another alternative, the rail is formed by the lip itself, each of the two parallel edges guiding. Thus, the accuracy of the movements of the module 205-3 is ensured by the cooperation of the wheel 300 with the rail 305. The module 205-3 is also used as a guide for the modules 205-1 and 205-2 via trolleys and guide rollers and a trolley type connection. This embodiment allows easy movement and quick storage of all modules. Each roof consists here of a curved part forming the upper part of the shelter, of two straight vertical parts or of low inclination, forming the sides of the shelter and of two straight parts inclined to join the curved part to the straight parts. vertical or at low inclination. Of course, other forms can be used. According to the shelter example described, the radius of curvature of the curved portion is constant on the same module and identical between several modules of the same shelter. However, the radius of curvature of the curved portion may vary from one shelter to another. Similarly, the lengths of the vertical straight portions and inclined portions forming the side of the modules are constant for the same module. However, the lengths of the vertical straight portions and the inclined portions forming the side of the modules vary from module to module so that the modules are interlockable. FIG. 4 represents an aerial view of the pool comprising guide rails 305 disposed on the terrace 115 on either side of the pool along a longitudinal axis, as close as possible to the lip 110. FIG. 5 illustrates an example of storage and deployment of modules 205-1, 205-2 and 205-3. As shown in Figures 5a, 5b and 5c, the largest module, mounted on rails and located on the staircase side, is preferably operated to discover the basin (Figures 5d and 5e). The set of modules can then be moved to discover the two ends of the basin (Figure 5f). While it is easier to handle the largest module, mounted on rails, nothing prevents to maneuver the smallest module. Although according to a preferred embodiment, the large module is mounted on rails arranged on the terrace closest to the lip and the other modules are mounted on single wheels, the longitudinal movement, that is to say along basin, can be assured in several other ways. In particular, all modules can be mounted on wheels or all modules can be mounted on rails. It is also possible to provide several modules mounted on the terrace, on rails, and several modules mounted on the rim, on single wheels. It is also possible to mount one side of the modules on rails and the other on the edge. Alternatively, the largest module can be fixed on the terrace and receive the other modules when opening. As described in the following description, the rollers used (simple or sheave) are standard commercial type and are fixed on the modules through the corner blocks that connect the hoops and the bank. The displacement of the modules is facilitated by an ergonomic push mechanism preferably located on at least one of the end modules of the shelter. Figure 6, including Figures 6a, 6b and 6c, shows a first example of an end panel, or facade, of a shelter in a closed position (Figures 6a and 6c), in an open position (Figure 6b). The facade is preferably mounted on the largest module, that is to say the module mounted on rails which is operated to cover and discover the pool. The facade 600 comprises a structure 605 whose shape is determined by that of the shelter. According to a particular embodiment, the facade 600 consists of removable fixed elements 610 and removable movable elements 615, preferably located in the lower part of the panel and whose length advantageously corresponds approximately to the width of the module on which they are mounted. In a first position, illustrated in Figure 6a, the facade 600 closes the end of the shelter. In an open position, illustrated in Figure 6b, the movable portion is raised along a horizontal axis, thus allowing the panel to go over the edge if the pool is equipped with overflowing margins. In addition, the movable part comprises handling handles 620-1 and 620-2, here retractable in the upper edge of the movable part of the facade structure, for example, by telescopic tubular interlocking. According to a particular embodiment, a portion of the handle may be of larger section, possibly covered with foam, to be more comfortable. Part of the section of the upper edge of the movable part is then adapted to receive the portion of the handling handle having a larger section.

  When the movable elements of the panel are arranged in the open position and the handling handles are deployed, the handles are arranged in such a way that they allow the users to easily maneuver the associated module. Indeed, the handling handles are advantageously located at a height of approximately between eighty centimeters and one meter thirty above the terrace, preferably one meter ten. The user is therefore at ease to exert a pushing or pulling force on these handling handles and thus move the module or modules. According to this characteristic, the user can move along the basin 625, without being hampered by the basin, the coping and the rails.

  Alternatively, the handles are removable and are put in place only to maneuver the shelter. The attachment of such handling handles may in particular be made by interlocking.

  A latching or magnetic locking system is advantageously used to keep the moving part of the pinion in the open position. The facade may consist of several elements. Each element is preferably easily removable to open at least partially the shelter. It is thus possible, for example, to remove the central element as shown in Figure 6c to allow air to circulate inside the shelter. The number and arrangement of items vary according to the needs and wishes of the user.

  Figure 7, including Figures 7a, 7b and 7c, illustrates a second example of facade 600 '. Figure 7a shows the facade 600 'in a closed position, Figure 7b shows the facade 600' in an open position and Figure 7c shows an example of a retractable handle. The facade 600 'here comprises the structure 605' whose shape is determined by that of the shelter.

  Like the facade 600, the facade 600 'consists of removable fixed elements 610' and removable movable elements 615 ', preferably located in the lower part of the panel and whose length advantageously corresponds approximately to the width of the module on which they went up. In a first position, illustrated in Figure 7a, the facade 600 'closes the end of the shelter. In an open position, illustrated in Figure 7b, the movable portion is raised in a vertical movement, allowing the panel to go over the edge if the pool is equipped with overflowing margins. The raising movement is linked to a guiding mechanism comprising, for example, rails 700-1, 700-2 and 700-3 fixed to the movable part 615 ', cooperating with guides 705-1, 705-2 and 705 -3 fixed on the structure 605 'or on the fixed part 610'. According to a preferred embodiment, the displacement of the movable part 615 'is assisted by a jack to limit the forces. A locking system of the latch or jack type is advantageously used to keep the movable part of the facade in the open position. The closed position is maintained by the only force of gravity that can be completed by the use of a latch type locking system.

  In addition, the movable portion includes handling handles 620'-1 and 620'-2 to facilitate the operation of the shelter. The handles 620'-1 and 620'-2 attached to the structure 605 'of the facade can be fixed, retractable or removable. Like the 620-1 and 620-2 handgrips, the handles 620'-1 and 620'-2 are preferably attached to the moving part to allow users to easily maneuver the associated module when the movable elements of the facade are arranged in open position. They are advantageously located at a height approximately between eighty centimeters and one meter thirty above the terrace, preferably one meter ten. The user is therefore at ease to exert a force of pushing or pulling on these handles and thus move the module or modules. According to an embodiment similar to that shown in Figure 6, the handles 620'-1 and 620'-2 are retractable in the structure of the facade, for example, by telescopic tubular interlocking. Alternatively, the handles 620'-1 and 620'-2 are retractable according to a mechanism using, for example, a deformable parallelogram, as shown in Figure 7c. According to this embodiment, two elements 710 are fixed on the upper edge of the movable part 615 ', these elements being pivotable in the same plane, for example the plane of the movable part. The other ends of these elements 710 are fixed to the handling handle 620'-1 according to the same principle of pivoting. The parallelogram formed by the elements 710, the upper edge of the movable part and the handling handle 620'-1 is deformable and can take, in particular, two positions. A first position stores the handling handle 620'-1 along the upper edge of the movable portion while a second position allows to deploy the handling handle 620'-1 which then extends outwards, beyond the side of the moving part, allowing the user to easily maneuver the shelter.

  As with the facade 600, the facade 600 'may consist of several elements, each element preferably being easily removable to open at least partially the shelter. It should be noted here that the movement of the movable part of the facade is such that this part can be easily disassembled by extending the lifting movement. However, to avoid any unwanted disassembly, a safety catch can be used so that the lifting movement of the movable part is limited and it is necessary to unlock the mechanism to prolong the lifting movement and thus disassemble the part mobile. The number and arrangement of items vary according to the needs and wishes of the user. Thus, the facade described allows, in raised position, to span the curbs without risk of friction on the ground, regardless of the difference in level between the coping and the terrace, without requiring space in front of and / or behind the facade. The handles integrated or fixed to the structure of the facade offer a goodergonomie of opening of the facade and maneuvering of the shelter.

  Each module of the shelter is advantageously made by an assembly of profiles, corner pieces and planar or curved surface elements. FIG. 8 illustrates a portion of a module 800 comprising profiles 805, corner pieces 810 and surface elements 815. The horizontal profiles located in the lower part are called the edges while the profiles extending from one side to the other of the shelter are called the arches. The profiles 805 are preferably made of a rigid material, light and at least slightly oxidizable, such as aluminum. According to a particular embodiment, the profiles 805 are nested in the corner elements 810 and adapted to receive the surface elements 815. The profiles 805 and the corner elements 810 advantageously incorporate a structure adapted to evacuate the water. rain from outside and condensation water from the inside. The corner elements 810 are also made of a rigid, lightweight and at least slightly oxidizable material, such as a synthetic material such as nylon. The corner elements are here designed to reduce the number of types of corner elements needed to make a shelter. Thus, the lower corner elements are particularly adapted to receive rollers, to receive a trolley to create a movable junction between several modules, to receive rollers for facilitating the movement of one module relative to another, to receive fasteners to maintain the shelter on the ground in a given position and to evacuate rainwater and condensation. The surface elements 815 are preferably made of a transparent or translucent material, resistant to external conditions such as temperature variations and light, such as polycarbonate. Figure 9 illustrates an exemplary corner element 900 for holding the elements of the lower part of the shelter. The corner element 900 and symmetrical along a vertical plane normal to the longitudinal axis of the shelter, for which the reference 9005 is used in the following description, are adapted to join all the profiles of the lower part of the shelter, that is to say all the banks and all the lower parts of the arches, for all the modules.

  The corner elements 900 and 9005 are also adapted to join several modules rigidly or movably. The corner element 900 consists of three main parts: a visible part 905, a hidden part 910 adapted to receive a vertical section, that is to say the lower part of a hoop, and a hidden part 915 adapted to receive a horizontal profile, that is to say a bank. These three parts are integral with each other, the corner element 900 is preferably made in one piece by molding or machining. The visible portion 905 comprises a cavity 920, preferably substantially cubic, formed on the inner face of the shelter, an opening 925 formed on the front face and communicating with the cavity 920 and two openings 930 formed on the upper part of the face before, these openings being blind or through. On the outer face of the shelter, the visible part comprises an open cavity 935 formed along a horizontal axis, adapted to cooperate with a horizontal profile fitted on the hidden part 915 to form a slide adapted to cooperate with a guiding device such as a trolley.

  The hidden portion 910 here comprises a vertical through opening 940 adapted to evacuate a portion of the condensation water and / or runoff. The hidden portion 915 comprises an opening 945 adapted to receive a wheel, simple or sheave, whose axis of rotation is maintained in an opening 950 formed in the hidden part 915, along a horizontal axis perpendicular to the interlocking axis a bank on the hidden portion 915, allowing the rolling of the corner element 900 (and therefore the module) on the ground. The open form of the opening 950 accommodating the axis of the wheel allows to consider a fixing of the wheel by clip allowing a quick change of wheel in the context of after sales service or the type of roulette (single or sheave) as part of a change in driving configuration without dismantling all or part of the roof. Guiding between the different modules is preferably provided by a rigid connection at one end of the modules and a contact roller contact at the other end of the modules. The substantially cubic cavity 920 is adapted to receive a device for adapting the corner element 900, in particular a guiding device (roller contact connection) or a connecting device (rigid trolley connection) as shown in FIG. Figure 10. Figure 10, including Figures 10a and 10b, illustrates two examples of adapter devices for the corner element shown in Figure 9. Figure 10a shows a 1000-1 trolley guiding device.

  The guide device 1000-1 comprises a body 1005 having substantially the shape of the cavity 920 and adapted to be inserted into this cavity and a fastening mechanism 1010, for example a screw or a rod that can be held by a clip. The use of a screw has the particularity of being manipulated from outside the shelter and being able to adjust the depth of the trolley according to the spacing between two modules. The device 1000-1 also comprises a trolley 1015 partially held in the body 1005 of the device according to a movable junction allowing a translational movement with respect to a vertical axis. The junction between the trolley 1015 and the body 1005 can be achieved, for example, by means of protuberances 1020 and vertical oblong openings 1025 disposed on either side of the device 1000-1. The other end of the trolley 1015 is adapted to cooperate, in particular, with the cavity 935 of the corner element 900, allowing a horizontal translational movement. More generally, the trolley 1015 is inserted into a groove running along the bank of the module immediately inside and allows, after adjustment, a rigid support between the two modules. Level difference variations between two neighboring modules of different sizes and in relative translation relative to each other are absorbed in real time during the operation of the shelter. The peculiarity of this system is to be able to set up and remove the trolley in a simple and fast way. The height adjustment is automatic and the depth adjustment is carried out by the fitter or the technician of the after-sales service of the outside of the shelter with the aid of the fixing means 1010. The curved shape of the trolley ensures the compensation in height when the difference in height between the coping and the terrace is high. Alternatively, the cavity 920 can receive a junction device 1000-2 as shown in Figure 10b. Like the device 1000-1, the device 1000-2 comprises a body 1025 and a fixing means 1030 allowing the insertion and fixing of the device 1000-2 in the cavity 920. The body 1025 of the device 1000-2 further comprises an opening 1035, formed on one of the faces of the body, a part of which is opposite the opening 925 when the device 1000-2 is in place in the corner element 900. The shape of the opening is such that, when the device 1000-2 is partially engaged in the cavity 920, it is possible to engage a key 1040 comprising two grooves 1045 and when the device is fully engaged in the cavity 920, the key 1040 is held in place rigidly by one of the grooves 1045 and a part of the wall of the body 1025. The length of the key 1040 and the arrangement of the grooves 1045 are such that two devices 900 and 9005 can be rigidly held against each other at the same time. using a 1040 key and two dispositi 1000-2 junction fs. It should be noted that the front face of the junction device 1000-2, that is to say the visible face, is preferably flat and aligned with the inner face of the corner element in which it is inserted and held in place to plug the cavity 920 to allow the rolling of a guide roller on the inner portion of the bank in which the corner member is fitted. FIG. 11 illustrates an angle element 900, fitted on a bank 805, to which is attached a roller guiding device 1100. The roller guiding device 1100 is fixed on the front face of the corner element 900 using, for example, screws inserted in openings 1105 arranged facing the openings 930 here threaded. The roller guiding device 1100 comprises a cavity in which is fixed a roller 1110 rotatable about a vertical axis. The roller 1110 includes a portion located outside the roller guide 1100 so that when the assembly consisting of the rim 805, the corner member 900 and the roller guide 1100 has a horizontal translation movement along the axis of the bank 805, the roller comes into contact with a profile (not shown) located opposite the shore 805, in the same direction, and avoids friction between these profiles. The rollers are preferably placed on the outer face of the banks relative to the shelter. The roller guiding device 1100 advantageously comprises a movable locking lug 1115 for fastening the assembly consisting of the bank 805, the corner element 900 and the roller guiding device 1100 to the floor using for example, a screw and a wheel 1120. When the movable locking lug is not used, it can be folded upwards against the roller guiding device 1100. In a manner of particular embodiment, the roller guiding device 1100 further comprises an orifice 1125 adapted to receive the end of the fixing screw comprising the wheel 1120 and to maintain the locking lug 1115 row. If the locking tab is used on a rail-mounted module, the locking tab is an equivalent element having the dual function of anti-pulling and securing. FIG. 12 illustrates the mounting of two corner elements 900-1 and 900S-1 on a bank 1200-1 and the mounting of an angle element 900-2 on a bank 1200-2 allowing a translational movement of banks relative to each other along their longitudinal axis. Shore 1200-1 is located outside shore 1200-2 from the shelter. The corner element 900-2 comprises a roller guide device 1100. The corner element 9005-1 comprises a trolley guide device (1015). Long guidance is provided by the roller guide device mounted at the end of the smaller module, i.e. the inner module, opposite the trolley guide device. The roller of the roller guide device is a contact piece for maintaining the two modules at a minimum distance, selected and adjustable, from one another and to maintain the relative positioning of the two modules during the maneuver of the shelter. Thus, once in place and adjusted, the roller 1110 rolls and bear on the inner face of the edge of the profile 1200-1. In this way, he is hidden behind the shore. FIG. 13, comprising FIGS. 13a and 13b, represents an example of a fastening mechanism for anchoring the shelter to the ground and preventing any inadvertent movement related to extreme loading conditions of the shelter, such as high winds and a loading load. snow. Such a fixing mechanism can in particular be used for winterizing swimming pools. As illustrated in FIG. 13a, a part 1300 of the fastening mechanism comprising two oblong open openings is inserted into the key grooves 1305 disposed in the lower part of the corner elements 900-1 and 900-2. There are of course other means of removably attaching the portion 1300 to the corner elements. Part 1300, resting on the ground, also has the function of wedging the shelter and thus relieve the pressure exerted on the wheels.

  This anti-crushing role makes it possible in particular to avoid the deformation of the rollers. The other end of the attachment mechanism 1300 includes a shape adapted to cooperate with a second portion 1310 of the fastening mechanism (Figure 13b). The second part 1310 of the fixing mechanism here comprises an opening for fixing this part to the ground using, for example, a screw (not shown). A fixing mechanism is preferably arranged at each module end and at each inter-module link, that is to say between two integral roofs.

  An infiltration of condensation water or runoff water is always possible, even through the seal placed around the surface elements, a water evacuation system is integrated into the shelter to allow the water to flow and not stagnate in the rabbet rebar, which can cause significant damage in winter frost. The principle is to create, by drilling, evacuations of water in the joining pieces. Water is drained through the sleepers to the connecting pieces. From there, the curved pan water flows into the basin. Similarly, the water of the right pan will flow in the profiles to the lip via the corner block as shown in Figure 14. Advantageously a broom is arranged in front of each wheel to remove the elements such as pebbles that could hinder the smooth rolling of the wheels. Naturally, to meet specific needs, a person skilled in the art of the invention may apply modifications in the foregoing description.
