Description

The present invention relates to telescopic shelters such as telescopic pool enclosures and more particularly to a monorail guide device for telescopic shelters. 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 roof element, also called module.

These shelters are characterized by the fact that each roof module 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.

In this family of shelters using the trundle principle, there are two distinct variants, the sliding shelters on rails whose roof modules are each equipped with wheels adapted to cooperate with rails fixed to the ground and sliding shelters whose roof modules are each equipped with wheels adapted to roll directly on the ground Sliding shelters whose modules are adapted to roll directly and freely on the ground have the advantage of completely freeing the entourage of the shelter when it is folded, by example at the end of a swimming pool. In addition, the use of this technique is economical insofar as it does not require any specific installation. However, the handling of these shelters is not easy because of the weight of the modules. In addition, the size of the structure generally causes a certain elasticity thereof and therefore, when manipulated, a deformation that causes a crabbing phenomenon. Therefore, a wheelhouse usually requires two people (one on each side) to be handled. It is also necessary that the surface on which is moved shelter is perfectly regular so that the wheels do not lock in the ground. It should also be noted that after several opening and closing operations, the shelter may move relative to its initial position and that it is then difficult for the user to put it back in place so that the points fixing the structure are found in line with the attachment devices, such as threaded holes, present on the ground. A particular advantage of sliding shelters on rails is the guiding of the roof modules during their displacement during the opening and closing of the shelter. This technique makes it possible in particular to maintain a constant distance between each of the modules and thus to prevent them from blocking against each other because of the phenomenon of crabbing. A rail shelter can usually be handled by a single person. In addition, the smooth surface of the rails makes it easier for the user to manipulate the modules, since the mass of the module is easier to set in motion and to overcome the earthwork defects frequently encountered, particularly in the vicinity of pool basins such as water drainage slopes and flatness or joint gaps between slabs. Nevertheless, this technique has several disadvantages. In particular, each module being guided on two opposite sides over a length determined by the movement of the modules, the location of the shelter gives way to many rails, the presence of which is particularly unsightly, when it is folded.

In addition, the presence of these rails creates a real barrier at ground level whose width can reach several tens of centimeters. This barrier is dangerous for people who can get their feet in or get burned when the rails, usually metal, have been in the sun for several hours. It is also a nuisance, especially for people with reduced mobility. In addition, this barrier forms a trap for many elements such as dead leaves and twigs that can only be removed by the ends of the rails, making maintenance difficult.

Finally, the use of this technique requires additional installation costs related to the elements used and the workforce. The invention solves at least one of the problems discussed above. The invention thus relates to a telescopic shelter module comprising a plurality of modules, said module comprising a plurality of wheels adapted to confer on said module a translational movement faculty substantially horizontal, along the longitudinal axis of said shelter, at least a wheel of said plurality of rollers, called first wheel, being adapted to cooperate with a guide element fixed to the ground and at least one second wheel, distinct from said first wheel, being adapted to roll freely on the ground, said first and second casters being mounted on opposite sides of said module. The module according to the invention thus allows simple manipulation by a single person of the telescopic shelter, at least one module being self-guided by a guide element. In addition, the presence of guiding elements on one side of the module does not constitute an obstacle or a risk for the user, does not trap undesirable and does not require any particular maintenance. It also makes it possible to limit the number of parts necessary for the implementation of the shelter as well as the installation time of this one.

According to a particular embodiment, said first wheel comprises a groove adapted to cooperate with a projection of said guide element. Alternatively, said guide element may comprise at least two projections forming a groove adapted to cooperate with said first wheel. Still according to a particular embodiment, said first and second rollers roll at different heights when said module is used to place the shelter as close to a basin while positioning the guide element so as to limit the embarrassment caused by it. Advantageously, said first wheel is also adapted to roll freely on the ground so that the module is adapted to cooperate with a guide element and to roll freely on the ground in order to reduce the size of the guide element and therefore, to limit the inconvenience that it can cause. The invention also relates to a telescopic shelter comprising at least one module as described above. According to a particular embodiment, said shelter further comprises a guide element, said module being movable between at least two distinct positions, a first position being a storage position of said shelter and a second position being a deployment position of said shelter, said guide member extending for a length less than the displacement length of said at least one wheel between said at least two positions. The telescopic shelter according to the invention thus combines the ease of handling with a reduction of the inconvenience caused by the presence of guiding elements. Still according to a particular embodiment, said shelter further comprises at least one second module, said at least one second module comprising a plurality of wheels adapted to roll freely on the ground, at least one of said wheels of said at least one second rolling module. on the same plane as one of said first and second wheels when said shelter is implemented. The telescopic shelter according to the invention thus allows the shelter to be placed closer to a pool and to limit the inconvenience caused by the presence of guiding elements.

Advantageously, at least one end of said guide element comprises a shape adapted to facilitate the engagement of said first wheel on said guide element. Similarly, at least one end of said guide element preferably comprises a stop adapted to limit the displacement of said first wheel so as to limit the amplitude of movement of the modules. Other advantages, aims and features of the present invention will become apparent from the following detailed description, given by way of non-limiting example, with reference to the appended drawings, in which: FIG. 1 schematically represents a swimming pool that can be protected by a telescopic shelter; FIG. 2, comprising FIGS. 2a and 2b, illustrates an example of a telescopic shelter; - Figure 3 shows a sectional view of a shelter and a pool along a transverse axis; FIG. 4, comprising FIGS. 4a to 4f, illustrates an example of storage and deployment of the modules forming a telescopic shelter; FIG. 5, comprising FIGS. 5a, 5b and 5c, illustrates a first example of a mixed wheel, adapted to roll on a rail and on the ground, and of an associated rail, in a lateral section, a longitudinal section. and a view from above, respectively; FIG. 6, comprising FIGS. 6a, 6b and 6c, illustrates a second example of a mixed wheel, adapted to roll on a rail and on the ground, and of an associated rail, according to a side section, a side view. and a view from above, respectively; FIG. 7, comprising FIGS. 7a, 7b and 7c, is a side view of a part of a shelter according to the invention, illustrating the displacement of a module adapted to roll on a guide rail and on the ground when this module is at one end of the rail, in the center thereof and at its other end, respectively; FIG. 8, comprising FIGS. 8a and 8b, is a perspective view of a swimming pool comprising guide rails arranged according to two embodiments, in accordance with the invention; FIG. 9 illustrates a part of a module comprising profiles, corner pieces and surface elements; FIG. 10 illustrates an example of an angle element intended to hold the elements of the lower part of the shelter; Figure 11, including Figures 11a and 11b, illustrates two examples of adapter devices for the corner element shown in Figure 9; - Figure 12 illustrates a corner member, fitted on a profile, on which is fixed a roller guide device; - Figure 13 illustrates the mounting of corner elements on two profiles allowing a translational movement of the profiles relative to each other along their longitudinal axis; and - Figure 14, including Figures 14a and 14b, shows an example of a fastening mechanism for anchoring the shelter to the ground. 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 pool round consists of a lip 110 separating the pool 105 from a terrace 115 formed around the pool. The curb is here the stone zone about twenty five to thirty centimeters wide which surrounds the basin resting on the frame of the pool and the terrace is the peripheral zone 25 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. Figure 2, including Figures 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 205-3 cover the entire pool. Although each module here consists of two roofs, it should be noted that each module can be made from a single roof structure or, conversely, multiple roofs. Each shelter is preferably composed of at least two modules, preferably three, corresponding to different types of roofs allowing the nesting of the modules one under the other according to the trundle principle. Advantageously, the various modules making up 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.

Alternatively, all modules can be mounted on the terrace or on the top of the coping. Similarly, the modules can be mounted according to any of configurations that some modules are mounted in whole or partially on the terrace while others are mounted in whole or partially on the upper part of the lip. 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 at least partially on rails, is advantageously positioned on the side of the staircase to compensate for the height difference between the lip 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. An object of the invention is to combine the principles of rail rolling and ground running by placing the rails so as not to impede normal traffic around the basin. According to a particular embodiment, the guide rails are arranged on one side of the basin, along its longitudinal axis, against the lip, the length of the rails being approximately equal to that of the shelter in the deployed position. On one side of the basin, all the modules are preferably mounted on rails, the rails being advantageously fixed on the terrace, closer to the lip. On the other side of the basin, the modules are mounted on simple wheels directly on the ground, on the lip or on the terrace, at least one of the modules, preferably the external module, being mounted on the terrace. 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 on one side of the basin while the module 205-3 is supported on the terrace 115, closest to the lip. According to a particular embodiment, the modules 205-1, 205-2 and 205-3 are, on this side, mounted on single rollers 310.

On the other side, the modules 205-1, 205-2 and 205-3 are supported on the terrace 115, closer to the lip. According to a particular embodiment, the modules 205-1, 205-2 and 205-3 are, on this side, mounted on rollers 300 adapted to cooperate with guide rails 305 whose shape is adapted to control the movement of the 300 wheels.

The rails 305 may have, for example, central protuberances cooperating with grooves of the rollers 300. Alternatively, each rail 305 may have two protuberances forming a central groove adapted to receive and guide a wheel 300, as shown. Thus, the precision of the movements of the modules 205-1, 205-2 and 205-3 is ensured by the cooperation of the rollers 300 with the rails 305. Alternatively, only one or more modules may be provided with rollers 300 adapted to cooperate with guide rails, these modules then being used as a guide for the other modules via trolleys and guide rollers and a trolley type connection. 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. Alternatively, the radii of curvature can be variable on the same module and can vary from one module to another. Similarly, the lengths of the vertical straight portions and inclined portions forming the side of the modules can be variable on the same module.

Figure 4 illustrates an example of storage and deployment of modules 205-1, 205-2 and 205-3. As shown in Figures 4a, 4b and 4c, the largest module, located on the staircase side, is preferably operated to discover the basin (Figures 4d and 4e). The set of modules can then be moved to discover the two ends of the basin (Figure 4f). While it is easier to handle the largest module nothing prevents to maneuver the smallest module.

Although according to a preferred embodiment, all the modules are, on one side of the basin, mounted on single wheels and, on the other side of the basin, on wheels adapted to cooperate with guide rails arranged on the terrace at closer to the lip, the longitudinal displacement, that is to say along the basin, can be assured in several other ways. In particular, some modules can be entirely mounted on single wheels, on the coping or on the terrace. The rollers used for the modules rolling directly on the ground are preferably of standard commercial type and are fixed on the modules by means of corner blocks which connect the arches and the banks. The wheels used for the modules mounted on rails may be of mixed type, that is to say, adapted to roll directly and freely on the ground indifferently on a rail and to cooperate with a guide rail. FIG. 5, comprising FIGS. 5a, 5b and 5c, illustrates a first example of a mixed wheel, adapted to roll on a rail and on the ground, and of an associated rail, in a lateral section, a longitudinal section and a view from above, respectively. According to the example illustrated in FIG. 5a, a standard wheel 300 is guided by a guide rail comprising two protruding parts 305-1 and 305-2, creating a groove between them, the lower part of which forms a tread 305. -3. The guide rail is here fixed on the terrace 115, at the edge of the lip 110. The groove formed by the projecting parts 305-1 and 305-2 is adapted to receive the lower part of the wheel 300 so as to guide the wheel. ci along a longitudinal axis. According to this example, the wheel 300 is inserted into a cavity of a corner element 500, itself connected to the module 205-3, and held therein by an axle 505. The difference in height between the surface of the terrace 115 and the bottom of the groove formed by the protrusions 305-1 and 305-2, that is to say the thickness of the tread 305-3, is preferably small compared to the diameter of the wheel 300 to allow the latter to pass easily from the terrace surface to the rolling band 305-3 and limit the height variations between the module 205-3 and the neighboring module. The elements 305-1 and 305-2 can also be distinct, the tread band then being located on the terrace. Figure 5b shows the end of the rail implemented in a central longitudinal section. As illustrated, the ends of the protrusion 305-1 and the tread 305-3 are bevel-shaped 515 and 520, respectively, to facilitate the transition of the wheel 300 between a rolling position 525 on the rail and a rolling position 530 on the ground. The shape of the end of protrusion 305-2 (not shown) is similar to that of protrusion 305-1. The beveled shape of the end of the rail also reduces the risk of injury to a person circulating in the vicinity thereof. Figure 5c shows an example of outwardly flared shape of the ends of the projections 305-1 and 305-2. This shape increases the width of the rolling band 305-3 at the end of the rail and thus facilitates the passage of the wheel 300 of the terrace 115 to the tread 305-3 when the latter are not perfectly aligned. FIG. 6, comprising FIGS. 6a, 6b and 6c, illustrates a second example of a mixed wheel, adapted to roll on a rail and on the ground, and of an associated rail, in a lateral section, a side view and a view from above, respectively.

According to the example shown in Figure 6a, a roller 300 comprises a groove adapted to cooperate with a guide rail whose section has a projection 305-4 having approximately the shape of the groove. The rail is here fixed on the terrace 115, on the edge of the lip 110. As before, the wheel 300 is inserted into a cavity of an angle element 500, itself connected to the module 205-3, and maintained in the latter by an axle 505. Advantageously, the diameters of the wheel and the bottom of the groove are such that when the wheel 300 is positioned on the guide rail, the bottom of the groove is in contact with the projection of the rail and that the outer portion of the wheel does not contact the lower portions 305-5 and 305-6 of the rail. Alternatively, the lower portions 305-5 and 305-6, or the corresponding parts of the terrace if the guide rail does not comprise lower portions 305-5 and 305-6, can be used as running strips, the protrusion being simply used as a guide. The outer part of the wheel 300 is chosen so as not to damage the terrace when the module is moved on the ground in the absence of rail. The outer portion of the wheel 300 preferably comprises a tread advantageously coated with a material such as rubber. The difference between the height of the projection 305-4 and the depth of the groove of the wheel 300 is preferably small compared with the diameter of the wheel 300 to allow the latter to easily move from the rolling position on the terrace to the rolling position on the guide rail and to limit the height variations between module 205-3 and the neighboring module. Figure 6b shows the end of the rail implemented in a side view. As illustrated, the end of the projection 305-4 and the lower portion 305-6 are bevel-shaped 515 and 520, respectively, to facilitate the transition of the roller 300 between a rolling position 525 on the rail and a rolling position 530 on the ground. The shape of the end of the lower portion 305-5 (not shown) is similar to that of the lower portion 305-6. The beveled shape of the end of the rail also reduces the risk of injury to a person circulating in the vicinity thereof. Figure 6c shows the tapered shape of the projection 305-4. This shape facilitates the passage of the wheel 300 of the deck 115 to the projection 305-4 when it is not perfectly in alignment with the groove of the wheel 300. The height of the rails 305 is preferably less than or equal to that of the lip 110. FIG. 7, comprising FIGS. 7a, 7b and 7c, is a side view of a portion of a shelter according to the invention, illustrating the displacement of a module adapted to rolling on a rail 305 and on the ground when this module is located at one end of the rail, in the center thereof and at its other end, respectively.

As shown in FIGS. 7a and 7c, when the module 205-3, comprising the mixed rollers 300, is positioned at the end of the rail 305, a mixed wheel is in rolling position on the ground while another wheel 300 is in rolling position on the rail 305.

If the module is moved in one direction, the two mixed wheels 300 are then in rolling position on the ground. If the module is moved in the other direction, the two mixed rollers 300 are then in rolling position on the rail 305 as illustrated in Figure 7b. Depending on the amplitude of displacement of the modules, it is possible to combine the use of mixed castors and wheels adapted to cooperate with a rail on the same module. According to this configuration, it is possible to provide a stop at one of the ends of the guide rails in order to limit the amplitude of movement of the module comprising this combination of rollers so that the module can leave the guiding device only a side. FIG. 8, comprising FIGS. 8a and 8b, is a perspective view of a swimming pool comprising a basin 105, a lip 110, a terrace 115, a staircase 120 at the end of the basin and rails 305 arranged according to two embodiments. according to the invention.

According to the first example illustrated in FIG. 8a, the rails 305, placed on the terrace 115 near the lip 110, have a length determined by the amplitude of displacement of each of the modules between a deployment position of the shelter and a storage position of the latter, at the end of the pool, on the opposite side of the stairs 120.

Although these rails protrude beyond the ends of the basin, it was observed that access to the basins was generally located on one side or at the end of the basin but rarely on both sides of a basin. Therefore, the implementation of rails 305 in the configuration shown in Figure 8a, on one side of the basin, optimizes the guiding modules while limiting the inconvenience caused by the presence of rails on the ground. The rails used to guide the interior module 205-1 extend from the storage position of the shelter to the module position when the shelter is deployed. Assuming that the storage position of the shelter is at the edge of the basin, the length of the rails associated with the module 205-1 is therefore approximately equal to twice the width of the module 205-1. Similarly, the rails used to guide the central module 205-2 and the outer module 205-3 extend from the storage position of the shelter to the position of these modules when the shelter is deployed, respectively. Starting from the same hypothesis as previously, according to which the storage position of the shelter is situated at the edge of the basin, the length of the rails associated with the module 205-2 is therefore approximately equal to the sum of the width of the module 205-1 to twice the width of the module 205-2 and the length of the rails associated with the module 205-3 is therefore approximately equal to the sum of the width of the modules 205-1 and 205-2 with twice the width of the module 205-3. The second example illustrated in FIG. 8b differs from the example shown in FIG. 8a in that the rails 305 disposed on the deck 115 near the lip 110 all have the same length, substantially equal to that of the lip 110. According to this embodiment, mixed-type rollers are used to allow certain modules to roll on the terrace, in the absence of a guide rail.

There are many other embodiments combining including the use of wheels adapted to cooperate with a rail, mixed casters and simple roulette adapted to roll directly on the ground (on the terrace or on the lip). According to a particular embodiment, a single guide rail is used, on one side of the basin, to guide, preferably, the widest module that drives the other modules during the handling of the shelter. Thus, the implementation of a single rail on one side of the basin, preferably against the lip, considerably limits the discomfort caused by the presence of ground rail.

Advantageously, at least one of the facades of the shelter is advantageously removable or liftable to allow stepping over the lip without risk of friction on the ground, regardless of the difference in level between the lip and the terrace. Each module of the shelter is preferably made by an assembly of profiles, corner pieces and surface elements, planar or curved. FIG. 9 illustrates a portion of a module 900 comprising profiles 905, corner pieces 910 and surface elements 915. 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 905 are preferably made of a rigid material, light and at least slightly oxidizable, such as aluminum. According to a particular embodiment, the profiles 905 are nested in the corner elements 910 and adapted to receive the surface elements 915. The profiles 905 and the corner elements 910 advantageously incorporate a structure adapted to evacuate the water from rain from outside and condensation water from the inside. The corner elements 910 are also made of a rigid material, light and at least slightly oxidizable, 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, a trolley to create a movable junction between several modules, rollers to facilitate the movement of one module relative to another, fasteners to keep the shelter on the ground in a given position and to evacuate rain and condensation water.

The surface elements 915 are preferably made of a transparent or translucent material, resistant to external conditions such as temperature variations and light, such as polycarbonate. Figure 10 illustrates an exemplary corner element 1000 for holding the elements of the lower part of the shelter. The angle element 1000 and its symmetrical in a vertical plane normal to the longitudinal axis of the shelter, for which reference 10005 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 1000 and 10005 are also adapted to join several modules rigidly or movably. The corner element 1000 consists of three main parts: a visible part 1005, a hidden part 1010 adapted to receive a vertical section, that is to say the lower part of an arch, and a hidden part 1015 adapted to receive a horizontal profile, that is to say a bank. These three parts are integral with each other, the corner element 1000 is preferably made in one piece by molding or machining.

The visible part 1005 comprises a cavity 1020, preferably substantially cubic, formed on the inner face of the shelter, an opening 1025 formed on the front face and communicating with the cavity 1020 and two openings 1030 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 1035 formed along a horizontal axis, adapted to cooperate with a horizontal profile fitted on the concealed part 1015 to form a slide adapted to cooperate with a guiding device such as a trolley. The hidden portion 1010 here comprises a vertical through opening 1040 adapted to evacuate a portion of the condensation water. The hidden portion 1015 comprises an opening 1045 adapted to receive a single or grooved wheel, whose axis of rotation is maintained in an opening 1050 formed in the hidden part 1015, along a horizontal axis perpendicular to the interlocking axis a bank on the hidden portion 1015, allowing the rolling of the corner element 1000 (and therefore the module) on the ground. The open shape of the opening 1050 accommodating the axis of the wheel makes it possible to envisage fixing the wheel by clip allowing a quick change of wheel in the context of after-sales service or the type of wheel (single or throat) 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 1020 is adapted to receive a device for adapting the corner element 1000, in particular a guiding device (roller contact connection) or a connecting device (rigid trolley connection) as shown in FIG. FIG. 11, comprising FIGS. 11a and 11b, illustrates two examples of adaptation devices for the corner element shown in FIG. 10. FIG. 11a represents a guiding device 1100-1 by trolley. The guiding device 1100-1 comprises a body 1105 having substantially the shape of the cavity 1020 and adapted to be inserted into this cavity and a fastening mechanism 1110, 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 1100-1 also comprises a trolley 1115 partially held in the body 1105 of the device according to a movable junction allowing a translational movement with respect to a vertical axis. The junction between the trolley 1115 and the body 1105 can be made, for example, by means of protuberances 1120 and vertical oblong openings 1125 disposed on either side of the device 1100-1. The other end of the trolley 1115 is adapted to cooperate, in particular, with the cavity 1035 of the corner element 1000, allowing a horizontal translation movement. More generally, the trolley 1115 is inserted into a groove running along the edge of the immediately-inner module 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 1110. 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 1020 can receive a junction device 1100-2 as shown in Figure 11b. Like the device 1100-1, the device 1100-2 comprises a body 1125 and a fixing means 1130 allowing the insertion and fixing of the device 1100-2 in the cavity 1020. The body 1125 of the device 1100-2 furthermore comprises an opening 1135, formed on one of the faces of the body, a part of which is opposite the opening 1025 when the device 1100-2 is in place in the corner element 1000. The shape of the opening is such that, when the device 1100-2 is partially engaged in the cavity 1020, it is possible to engage a key 1140 comprising two grooves 1145 and when the device is fully engaged in the cavity 1020, the key 1140 is held in place rigidly by one of the grooves 1145 and a part of the wall of the body 1125. The length of the key 1140 and the arrangement of the grooves 1145 are such that two devices 1000 and 10005 can be rigidly held against each other at the same time. using a 1140 key and two di junction therapists 1100-2. It should be noted that the front face of the junction device 1100-2, i.e., the visible face, is preferably flat and aligned with the inner face of the corner element into which it is inserted and held in place to plug the cavity 1020 to allow the rolling of a guide roller on the inner portion of the bank in which the corner member is fitted.

FIG. 12 illustrates an angle element 1000, fitted on a bank 905, to which is attached a roller guiding device 1200. The roller guiding device 1200 is fixed on the front face of the corner element 1000 using for example, screws inserted into openings 1205 arranged opposite the openings 1030 here threaded. The roller guide device 1200 comprises a cavity in which is fixed a roller 1210 rotatable about a vertical axis. The roller 1210 includes a portion outside the roller guide 1200 so that when the assembly consisting of the edge 905, the corner member 1000, and the roller guide 1200 has horizontal translation movement along the axis of the bank 905, the roller comes into contact with a profile (not shown) located opposite the shore 905, 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 1200 advantageously comprises a movable locking lug 1215 for fastening the assembly consisting of the bank 905, the corner element 1000 and the roller guide device 1200 to the floor using for example, a screw and a wheel 1220.

When the movable locking lug is not in use, it can be folded upwards against the roller guiding device 1200. According to a particular embodiment, the roller guide device 1200 further comprises a port 1225 adapted to receive the end of the fixing screw comprising the wheel 1220 and to maintain the locking lug 1215 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. 13 illustrates the mounting of two corner elements 1000-1 and 10005-1 on a bank 1300-1 and the mounting of a corner element 1000-2 on a bank 1300-2 allowing a translational movement of banks relative to each other along their longitudinal axis. Shoreline 1300-1 is located outside shoreline 1300-2 from the shelter. The corner element 1000-2 comprises a roller guide device 1200. The corner element 1000S-1 comprises a trolley guide device (1115).

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, chosen 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 1210 rolls and bear on the inner face of the bank of the profile 1300-1. In this way, he is hidden behind the shore.

FIG. 14, comprising FIGS. 14a and 14b, represents an exemplary fixing 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 load of snow. Such a fixing mechanism can in particular be used for winterizing swimming pools. As illustrated in FIG. 14a, a part 1400 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 1000-1 and 1000-2. There are of course other ways to removably attach the portion 1400 to the corner elements. Part 1400, 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 1400 includes a shape adapted to cooperate with a second portion 1410 of the fastening mechanism (Figure 14b). The second portion 1410 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 is always possible, even through the seal put in place around the surface elements, a drainage system is integrated into the shelter to allow the water to s' 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 condensation water of the bent pan flows into the basin and the condensation water of the right pan will flow in the profiles to the curb via the corner block.

Advantageously a broom is disposed in front of each wheel to remove the elements such as pebbles that could hinder the smooth roll of the wheels.

Naturally, to meet specific needs, a person skilled in the field of the invention may apply modifications in the foregoing description. In particular, although the description is aimed in particular at swimming pool shelters, the invention can be implemented for other types of telescopic shelters.
