Definitions

• the present invention relates to a mobile shelter intended in particular for covering a swimming pool, comprising a plurality of arches, optionally nestable in a nesting fashion by displacement on a base of at least one arch of said plurality of arches, each arch being formed at each end and sometimes in the center of a support body and between each support body of a cover body.
• the prior art teaches in particular swimming pool shelters as defined above.
• the major drawback of these lies in the fact that these shelters must have a high mechanical strength in order to be able to withstand vertical loads due to snow or lateral loads due to wind.
• This imposes on the structure certain dimensional characteristics, of weight and rigidity which on the one hand affect the manufacturing cost and therefore the sale price, thus limiting the number of people who can acquire such a shelter, which on the other hand impose a significant space on the ground, the latter limiting the possibilities of installing shelters on swimming pools with a small space around them, and which finally by their weight associated with their too low rigidity, lead, in the case of shelters telescopic, of which said arches are nestable in a nesting fashion, the deformation of said arch when it is subjected to the unilateral longitudinal forces generated by a person seeking to move a single arch of said shelter, this deformation thus creating bracing effects, prohibiting the.
• the present invention proposes to overcome the above drawbacks and to provide other advantages.
• a mobile or portable shelter intended in particular for the cover of a swimming pool comprising a plurality of arches possibly nesting in a nesting fashion by displacement on a base of at least a first arch of said plurality of arches nestable, at least the first arch of said plurality of possibly nestable arches comprising several load-bearing bodies, a cover body linked laterally to said load-bearing bodies, characterized in that said load-bearing bodies are at least for their central part made of composite material made of a core of light material with a cellular structure, said core being surrounded by a layer of at least a second element with a fibrous structure impregnated with a layer of synthetic resin curable by polymerization.
• the resistance of the composite material is given essentially by the association of the second element with a fibrous structure and of the synthetic resin, the core of material with a cellular structure having the main role of keeping the fibrous structure and the synthetic resin in position. at time of polymerization.
• the cell structure may be chosen so as to contribute to the mechanical resistance of the whole of the structure thus constituted, in particular to the resistance to compression forces.
• the composite material used for the production of said support bodies comprises internal ribs made up of the second element with a fibrous structure impregnated with synthetic resin, arranged in the longitudinal or transverse direction of the support body and connecting the external layers thereof .
• the presence of said internal ribs advantageously makes it possible to increase the resistance of the structure thus formed to compressive, tensile and shear forces.
• the composite material used for the production of said carrier bodies of said shelter comprises a third element with a notably fibrous structure, inserted into the synthetic resin, in addition to or in partial replacement of said second element with fibrous structure.
• This addition advantageously makes it possible to increase the resistance of the structure thus constituted by the use of the properties complementary to this third element to that of the second element with a fibrous structure.
• the weight of the structure and in particular of said load-bearing bodies will be significantly lowered compared to that of the structures of the prior art.
• This characteristic allows the operator to easily maneuver said arch whether it is nestable in a nesting fashion in the previous one or whether it is simply transportable manually when the user wishes to discover the swimming pool.
• said carrier bodies are provided with inserts passing through them and the ends of which are integral with the walls and ribs of said carrier bodies, said inserts being made of a material different from said first three elements; these inserts advantageously allow the positioning of the support crosspieces of said cover body between said load-bearing bodies of said same arch, said crosspieces thus being perfectly secured to said load-bearing bodies.
• the inserts will pass through the carrier body partially; they will be integral with a wall of said carrier body and said inner longitudinal rib.
• said carrier bodies are provided with means of U-shaped inserts embedded longitudinally in the carrier body and emerging at the surface thereof; they are placed over the entire length of the carrier body; these inserts advantageously allow the establishment of the panels constituting said cover body as well as possible seals between two bearing bodies of two adjacent arches.
• This characteristic allows the easy and inexpensive realization of the assembly of the carrier bodies with the cover bodies, in particular thanks to the very limited number of means for fixing said crosspieces with said carrier bodies, this number being reduced to one; means for fixing each end of each cross member to said carrier body being sufficient. Furthermore, this characteristic makes it possible to produce an assembly avoiding the ingress of water flowing over the cover body and the bearing bodies inside the arch, the water possibly entering the U-shaped insert being channeled by this profile to the bottom of the carrier body.
• the opposite ends of two of said crosspieces are connected together by tensioning means, which may in particular be cables; these tensioning means are thus arranged diagonally at the level of the cover body.
• tensioning means constitute the diagonals of fixed length of a parallelogram; they thus prevent the deformation of said arch when an operator exerts a unilateral longitudinal thrust on one of the sides of said carrying bodies of said arch to move it; ifs therefore avoid the effects of bracing and allow the movement of a said arch of said shelter by a single operator, even for large shelters.
• the thickness of the carrier bodies is adjusted to the forces which the carrier body must resist; it will therefore be gradually decreased from the center of the carrier body to the ends thereof.
• This characteristic makes it possible on the one hand to reduce the cost of each of the load-bearing bodies by reducing the raw material and the manufacturing time necessary for the development of the load-bearing body, and on the other hand to reduce the size on the ground of the arches and therefore to make the best use of the space available for the shelter, particularly around the swimming pool.
• the carrier bodies can be made in several parts, the various parts then being able to be made of materials of different nature, for example the central part made of composite material as described above and the lateral parts made of metallic material.
• This characteristic advantageously makes it possible to use the mechanical strength and feasibility properties of the various materials; it also makes it possible to easily transport the various parts constituting said shelter from its place of manufacture to its place of establishment, the unit length of each of the parts of the bearing bodies being thus reduced.
• the assembly of the various parts of the carrier body will be carried out either using joint bars made of composite materials, or by embedding. This characteristic advantageously makes it possible to reduce the weight of the structure.

• the telescopic shelter more particularly intended to cover a swimming pool, comprises arches (3), possibly nesting in a nesting fashion thanks to the linear displacement of said arches on a base, which allows partial or total covering of the swimming pool.
• the shelter shown in Figure 1 comprises three arches (3) each constituted of three carrier body (1) and s' vr ody cover (2).
• the cover body (2) can be produced in several parts, possibly of a different nature, each of these parts then being interconnected by discontinuity crosspieces (18).
• the supporting bodies (1) as shown in FIG. 1 are made of composite material, examples of structure of which are given in FIGS. 2, 3, 4, 5 and 6. They can be in several parts, each part being in material of a possibly different nature as illustrated in FIG. 12.
• the carrier body has a rectangular section obtained by the arrangement on the various faces of the inner core called the first element (6), of layers of a second element with a fibrous structure (5), for example impregnated glass fibers synthetic resin (4) curable by polymerization.
• the core (6) may advantageously be made of expanded polystyrene foam or polyurethane foam, cardboard or any other low-cost material constituting a support for assembling the fibrous structure and the synthetic resin which is sufficiently rigid at the time of polymerization so that the geometry of the assembly is not changed in an uncontrolled manner during polymerization. If expanded polystyrene or polyurethane foam is used, the rigidity of these materials is too great to be able to bend them and thus be able to give the core (6) that they constitute the final form of the carrier body (1) without it breaking; to overcome this difficulty, partial cross sections (9) are made as shown in FIG.
• these cuts have the second advantage of constituting reserves of synthetic resin which after polymerization of the structure will be ribs and will contribute to the mechanical resistance of the bearing body and in particular to the resistance to compressive forces; an advantageous variant consists in placing the second element (5) with a fibrous structure inside these cutouts so that the mechanical resistance of the ribs thus formed is increased.
• the second element with a fibrous structure (5) will advantageously be glass fiber, carbon fiber, or any other material having a high mechanical strength associated with a low weight. It will be chosen and positioned in the structure so that its fibers are mainly oriented in the direction of the forces; thus, the fibers placed in the lower and upper outer walls (10) are mainly oriented in the long direction of the carrier body (1) as illustrated in FIG. 2b; the fibers placed in the sides (11) will preferably be oriented at 45 ° relative to the longitudinal direction of the carrier body; in an easier embodiment described in Figure 2d, the fibers are placed in the longitudinal and transverse directions of the carrier body (1) in proportion dependent on the mechanical stresses exerted on the hoop.
• the layers of fibrous structure (5) will project beyond their base wall, folded on the adjacent walls and will be made integral with the latter by the synthetic resin (4) with which all the fibrous structure layers (5) are impregnated.
• U-shaped inserts (7) are placed inside the carrier body (1) in the longitudinal direction of the latter. These inserts will advantageously allow the maintenance of the polycarbonate or other panels constituting the covering body (2) as well as the maintenance of seals, as will be described later.
• the establishment of the profile (7) is carried out at the time of the assembly of the core (6), the fibrous structure (5) and the synthetic resin (4); thus, in a single operation, a carrying bar is obtained ready to receive the covering body (2).
• the profile of these U-shaped inserts (7) will advantageously be determined so that their insertion inside the structure is mechanically resistant; this is obtained by giving them an external shape comprising hooking bosses (8).
• cefinsert (7) will be made of a material capable of being bonded by synthetic resin (4) so that this U-shaped insert can thus be made integral with the assembly formed by the fibrous structure ( 5) and the synthetic resin (4), be suitable for bending so as to be able to be adjusted to the shape of the carrier body (1) and to have a high resistance to aggressive atmospheric agents, such as aluminum alloys, plastics and composite materials.
• This third element will be arranged in the longitudinal direction of the carrier body and will be placed in the most mechanically stressed places of the section, for example in the parts furthest from the neutral fiber.
• This material will advantageously have a very high mechanical resistance such as for example carbon fibers or steel cables with very high mechanical resistance.
• Inserts (15) allowing the embedding of the support crosspieces (17) of the cover body (2) inside the carrier body (1) are placed transversely to the carrier body and parallel to the base on which the shelter moves. as illustrated in Figures 8a and 8b. These inserts (15) are made integral with the structure by bonding using synthetic resin (4) which provides the mechanical connection between the walls and ribs of the assembly and the inserts (15).
• inserts (15) are suitable for bonding by synthetic resin (4), of sufficient mechanical strength to transmit the forces of the crosspieces (17) supporting the cover body (2) to the carrier body (1) and of high resistance to aggressive atmospheric agents; they will advantageously be made of aluminum alloy, plastic material, composite material, stainless steel, ordinary steel treated on the surface so as to give them resistance to aggressive atmospheric agents, or any material having the properties required above. indicated.
• the cover body (2) and the cross members (17) and (18) have been assembled by fitting the cover body (2) into the U-shaped profiles (7) of the load-bearing bodies (1), then by embedding the support crosspieces (17) of the cover body (2) in the inserts (15), to permanently fix this assembly, it will suffice to place a fixing means (23 ), of any known nature, of the crosspiece (17) with the insert (15).
• Tensioning means (11) are placed between each of the bodies carrying the same arch; they connect the central part of a first support body (1) at the level of the embedding of the central crosspiece (17) in the latter with the top of the lateral part of the second support body (1) at the level of the embedding a crosspiece (17) in this second carrier body. As illustrated in FIGS. 9, 10 and 11, these tensioning means (11) cross at the center of the cover body (2) and pass between the cover body and the cross members (17) supporting the cover body. They thus constitute the diagonals of determined length of a parallelogram and therefore prevent this parallelogram from deforming; they thus avoid deformation of the arch when an operator exerts a thrust in one direction or in the opposite direction, the opposite side of the arch being driven simultaneously by means of crossed tensioning means.
• tensioning means (11) must be rigidly fixed to the carrier bodies (1) so that no relative displacement of the tensioning means with respect to the latter. This rigid fixing will be carried out by means of the inserts (15) for fixing the sleepers or inserts placed specially for this purpose in the bearing bodies (1).
• tensioning means will be determined so that they have a high mechanical resistance, that they can be bendable so as to be able to follow the curve of the arches and finally that they have a high resistance to aggressive atmospheric agents. ; thus these tensioning means could be carbon fiber or stainless steel cables or any other known tensioning means meeting the required characteristics.
• the carrier bodies (1) advantageously adopt a cross section of variable thickness, small in the lateral zones (21) little mechanically stressed and greater in the central part (20) which must withstand the highest mechanical stresses, so on the one hand to reduce the quantity of materials used for the production of the carrier body (1) and therefore reduce the cost, and on the other hand to allow a small footprint of the base on which rests and is moved the shelter.
• the carrier bodies (1) are interconnected by a plurality of crosspieces (17) supporting the cover body; sleepers (18) of different profile from that of the support sleepers (17), also make it possible to create discontinuities in the cover body; one of the original features of the invention resides in the embedding of these crosspieces in the cover body by means of the inserts (15) and by the use of these crosspieces to support the tensioning means (11) and thus prevent these are inside the cabin created by the pool enclosure as shown in Figure 8.
• the carrier body (1) may be made up of several parts, the central part (20) being of composite material, the lateral parts (21) being either of composite material or of another material, having properties complementary to that of the central part.
• the central part (20) must be made of a light material, of high mechanical strength and having good resistance to aggressive atmospheric agents; for the side parts which are less mechanically stressed, in addition to the cost, the mechanical strength and the resistance to aggressive atmospheric agents will also be considered as a criterion for the selection of materials, their ease of preparation and implementation; these lateral parts (21) of the carrier body may therefore be made of composite material or of an aluminum alloy.
• the simultaneous use of these various materials makes it possible to combine the best characteristics of each of them, the lightness and the mechanical strength of the composite material for the central part, the ease of implementation for the vertical part.
• the assembly of these various parts will preferably be carried out using fishplates of composite material which can either be screwed or bolted, or be glued.
• This assembly of the various parts of the carrier body can also be carried out without connecting ribs, the profiles of the various parts being determined to allow their embedding in each other.
• the central part (20) which is more mechanically stressed being of decreasing thickness starting from its center and going towards its ends; and generally larger than those of the lateral parts (21), which makes it possible to reduce the quantity of material used and likewise the space taken up on the ground of the shelter.
• This structure of the hoop in several parts also has the advantage of allowing easy transport of the various parts of the shelter, an arch being now made up of various parts of reduced unit size compared to that of the carrying body (1) produced in one piece.
• Figure 13 shows a mobile but not telescopic shelter; the advantage of the invention in this case lies in the low weight of the arches thus produced, which allows, when the user wishes to discover the swimming pool, the easy movement of each arch (3) by two operators placed on each side of this arch.
