Abstract

The shelter has movable sections (2-4), each comprising a longitudinal lower profile (10) having two vertical outer and inner side walls. The sections are fixed to the ground by cleats (36) fixed against one of the side walls. The cleats have a vertical upper tab and a horizontal lower tab to be fixed to the ground. The horizontal tab extends oppositely to the lower profile.

Description

The present invention relates to telescopic shelters, in particular for swimming pools.

More particularly, the invention relates to a telescopic shelter comprising a plurality of sections movable relative to each other in a longitudinal direction between at least one extended position where said sections at least partially cover a space to be protected and a retracted position where said sections are mutually nested, each section comprising at least one longitudinal lower profile which has two opposite side walls, and at least one of the sections being fixed to the ground by an anchoring member which comprises at least one vertical leg fixed to said section and a horizontal leg adapted to be fixed to the ground.

The document US-A-6,604,327 describes an example of such a shelter, wherein the anchoring member is a bracket fixed to an axial end of the section in question, which has the disadvantage of making the bracket twisted with respect to efforts tending to open the sections by mutual spacing of their longitudinal lower edges. This results in particular a risk of breaking of this square. This type of assembly also has a risk of tearing screws usually connecting the bracket to the profiles of the shelter.

The present invention is intended to overcome this disadvantage.

For this purpose, according to the invention, a shelter of the kind in question is characterized in that the anchoring member is fixed against one of the side walls of the longitudinal lower section, the horizontal leg extending opposite said section lower horizontal.

Thanks to these provisions, the strength of the ground anchorage is increased, since the organ is made to work. anchoring no longer in torsion to resume the bracing efforts tending to move laterally the longitudinal lower profile, but rather in shear at the junction between its vertical leg and its horizontal leg.

• la figure 2 est une vue similaire à la figure 1, dans la position rétractée de l'abri,
• les figures 3 et 4 sont des vues de détail en perspective montrant plusieurs parties de l'abri de la figure 1,
• la figure 5 est une vue en coupe verticale sur les bords inférieurs longitudinaux de deux tronçons adjacents de l'abri, en position rétractée,

On the drawings:

• FIG. 1 is a perspective view of a shelter according to one embodiment of the invention, in the deployed position,
• FIG. 2 is a view similar to FIG. 1, in the retracted position of the shelter,
• FIGS. 3 and 4 are detailed perspective views showing several parts of the shelter of FIG. 1,
• FIG. 5 is a vertical sectional view on the longitudinal lower edges of two adjacent sections of the shelter, in the retracted position,
• and Figures 6 and 7 are sectional views showing ground fastening brackets of different sections of the shelter.

In the different figures, the same references designate identical or similar elements.

Figures 1 and 2 show a telescopic shelter 1 which comprises a plurality of adjacent sections 2, 3, 4 movable relative to each other in a longitudinal direction X. The sections 2, 3, 4 are here three in number but could to be in a different number without departing from the scope of the invention.

• la position déployée visible sur la figure 1, où les tronçons 2, 3, 4 recouvrent un espace à protéger 6, par exemple une piscine ou autre,
• et la position rétractée visible sur la figure 2 où les tronçons 2, 3, 4 coopèrent par emboîtement mutuel et découvrent l'espace à protéger 6.

In the example shown in Figures 1 and 2, the section 4 of the shelter 1 is fixed and the sections 2, 3 are movable in translation in the X direction between:

• the deployed position visible in FIG. 1, where the sections 2, 3, 4 cover a space to be protected 6, for example a pool or the like,
• and the retracted position visible in Figure 2 where the sections 2, 3, 4 cooperate by interlocking and discover the space to be protected 6.

In the example shown, the section 2 comprises a generally removable end wall 5 while the section 4 has no end wall opposite the end wall 5: the end of the section 4 which is opposed to the end wall 5 could in this case be applied against a wall of a fixed building. Of course, the section 4 could also include an end wall similar to the end wall 5.

The sections 2, 3, 4 mentioned above preferably have similar structures, with the same length in the longitudinal direction X and slightly different dimensions in the plane perpendicular to the direction X to allow mutual interlocking of the sections 2, 3, 4 , the fixed section 4 being the widest in the example shown.

• de profilés en alliage léger ou autres,
• avec des plaques de remplissage transparentes ou non, par exemple réalisées en polycarbonate ou en Plexiglas® (polymétacrylate de méthyle ou PMMA).

The different sections 2, 3, 4 can be made by assembling:

• light alloy profiles or others,
• with transparent filler plates or not, for example made of polycarbonate or Plexiglas® (polymethyl methacrylate or PMMA).

The different profiles used for the different sections 2, 3, 4 of the shelter may have identical sections from one section to another.

• un profilé inférieur longitudinal 10 qui forme un bord inférieur longitudinal du pan latéral 8,
• un profilé supérieur longitudinal 11,
• un montant arrière 12, à l'extrémité du tronçon qui est la plus éloignée de la paroi d'extrémité 5,
• et un montant avant 13 à l'autre extrémité du tronçon considéré.

Each of the sections 2, 3, 4 of the shelter comprises a roof 7 which extends transversely to the longitudinal direction X between two vertical side panels 8. Each of the side panels 8 comprises for example a transparent wall of polycarbonate 9 lined by :

• a longitudinal lower profile 10 which forms a longitudinal lower edge of the lateral pan 8,
• a longitudinal upper section 11,
• a rear upright 12, at the end of the section that is farthest from the end wall 5,
• and an amount before 13 at the other end of the section in question.

• une paroi supérieure horizontale 14 dans laquelle est ménagée une gorge 15 ouverte vers le haut où est emboîtée la paroi 9 de polycarbonate,
• une paroi latérale extérieure 16 sensiblement verticale, orientée vers l'extérieur de l'abri et formant par exemple une paroi pleine,
• une paroi latérale intérieure 17 sensiblement verticale, orientée vers l'intérieur de l'abri et présentant par exemple une gorge latérale 18 sur toute sa longueur,
• et une extrémité inférieure 19 dans laquelle débouche une gorge 20 ouverte vers le bas, la gorge 20 pouvant également être ouverte sur toute la longueur du profilé inférieur longitudinal 10.

As shown in more detail in FIG. 5, each longitudinal lower profile 10 of each section 2, 3, 4 may for example have a generally rectangular general shape, with:

• a horizontal upper wall 14 in which is formed an upwardly open groove 15 which is fitted with the polycarbonate wall 9,
• a substantially vertical outer side wall 16, oriented towards the outside of the shelter and forming for example a solid wall,
• a substantially vertical inner side wall 17 oriented towards the inside of the shelter and having for example a lateral groove 18 over its entire length,
• and a lower end 19 in which opens a groove 20 open downwards, the groove 20 can also be open over the entire length of the longitudinal lower profile 10.

In the vertical grooves 20 of the longitudinal lower profiles are mounted wheels 21 which are rotatable about horizontal transverse axes Y perpendicular to the X axis. The wheels 21 may be in the form of horizontal disks, possibly with an enlarged periphery. They may be made for example of synthetic material, in particular polyamide 6-6 reinforced or not glass fibers or other, molded around a central metal hub 22 whose ends respectively journalled on the side walls 16, 17 of the section 10 .

More particularly, the ends of the hub 22 may each comprise an annular groove 23 which delimits an enlarged head 24 fitted into a channel 25 of the corresponding lateral wall 16, 17. The channel 25 in question can communicate with the vertical groove 20 by a slot 26 narrower than the enlarged head 24.

The wheels 21 rest on the ground 27 thus allowing the displacement of the corresponding shelter section in the longitudinal direction X. It will be noted that the wheels 21 are not guided by rails on the ground or the like.

Furthermore, rollers 28 are rotatably mounted in the lateral grooves 18 of each section (these rollers may however be omitted for the section 2 of smaller width, in which no other section fits).

The rollers 28 are rotatably mounted about vertical axes Z and may have the general shape of horizontal disks with an enlarged periphery. The rollers 28 may for example be molded from synthetic material, in particular polyamide 6-6 reinforced or not with glass fibers or the like, molded on a metal hub 29 whose ends are journalled on the walls of the profile which delimits the lateral groove 18 upwards and downwards.

More particularly, the ends of the hub 29 may each have an annular groove 30 which delimits an enlarged head 31 engaged in a channel 32 formed in the profile 10, this channel 32 opening into the lateral groove 18 through a longitudinal slot 33 narrower than the enlarged head 31 of the hub.

The rollers 28 project out of the lateral grooves 18 towards the inside of the shelter, so as to be able to roll against the corresponding side wall 16 of the adjacent section of the shelter during a relative displacement between the sections in the X direction. (The wall 16 thus forms a rolling surface for the rollers 28). Advantageously, a certain clearance is provided between the rollers 28 and the adjacent side wall 16, which helps to prevent jamming between sections during their movements.

The rollers 28 may for example have a radius of about 30 to 40 mm, they may project out of the profiles 10 for example of about 20 to 30 mm, and the clearance between the rollers 28 and the wall 16 which faces them can be for example from about 0 to 10 mm.

As shown in FIG. 3, the rollers 28 of each section are distributed substantially over the front half of the longitudinal lower profile 10, that is to say the half of the profile 10 which is closest to the end wall 5. in the example shown.

• un premier galet 28 disposé au voisinage de l'extrémité avant 34 du profilé 10, par exemple à une distance L1 comprise entre 10 et 20 cm de ladite extrémité avant 34,
• un deuxième galet 28 décalé vers l'extrémité arrière 35 du profilé 10 par rapport au premier galet 28, par exemple avec un écartement L2 de 8 à 20 cm entre les axes de rotation Z des premier et deuxième galets,
• un troisième galet 28 disposé vers l'arrière par rapport au deuxième galet, avec un écartement L3 supérieur à L2 entre les axes de rotation Z des deuxième et troisième galets, L3 pouvant par exemple être compris entre 20 et 30 cm et pouvant être par exemple au moins double de l'écartement L2,
• et un quatrième galet 28 disposé vers l'arrière par rapport au troisième galet, l'écartement L4 entre les axes de rotation Z des troisième et quatrième galets étant supérieur à l'écartement L3 susmentionné et pouvant être par exemple compris entre 40 et 50 cm, l'écartement L4 pouvant être par exemple sensiblement le double de l'écartement L3.

These rollers 28 may comprise, for example:

• a first roller 28 disposed in the vicinity of the front end 34 of the profile 10, for example at a distance L1 between 10 and 20 cm from said front end 34,
• a second roller 28 offset towards the rear end 35 of the profile 10 relative to the first roller 28, for example with a distance L2 of 8 to 20 cm between the axes of rotation Z of the first and second rollers,
• a third roller 28 disposed rearwardly with respect to the second roller, with a spacing L3 greater than L2 between the axes of rotation Z of the second and third rollers, L3 may for example be between 20 and 30 cm and can be for example at least twice the distance L2,
• and a fourth roller 28 disposed rearwardly with respect to the third roller, the distance L4 between the axes of rotation Z of the third and fourth rollers being greater than the above-mentioned gap L3 and which may be, for example, between 40 and 50 cm , the spacing L4 may be for example substantially double the distance L3.

Because the rollers 28 are closer to each other forwards, that is to say towards the section against which the rollers 28 can roll and which can fit into the section carrying the rollers 28, the sections are guided with great precision at the beginning of their mutual interlocking movement, which guarantees excellent guidance of the sections with a limited number of rollers 28. In addition, the distribution of the rollers at spacings substantially doubled by a roller to the other rearward, ensures that the lower sections 10 sections 2, 3, 4 never come into mutual contact during the interlocking movement of the sections, even if one of the movable sections 2, 3 is biased.

Furthermore, as shown in Figures 3 and 6, each of the movable sections 2, 3 of the shelter can be immobilized by anchoring members such as brackets 36 fixed to the ground. These brackets 36 may for example be two in number per section (one for each side panel), and may if necessary be arranged towards the inside of the shelter relative to the side panels 8 of the section.

• une patte inférieure horizontale 37 qui repose sur le sol 27,
• une patte supérieure verticale 38 qui s'étend vers le haut et qui présente une face externe verticale 39 en appui contre la paroi latérale intérieure 17 du profilé inférieur longitudinal 10 correspondant sur la majeure partie de sa hauteur, la patte 38 formant un contrefort 40 d'épaisseur croissante vers le bas jusqu'à la patte inférieure 37 (ce contrefort peut éventuellement être formé par deux nervures verticales au niveau des bords de la patte supérieure 38).

The brackets 36 may for example be molded in one piece of light alloy and include:

• a horizontal lower leg 37 which rests on the ground 27,
• a vertical upper leg 38 which extends upwards and which has a vertical outer face 39 bearing against the inner side wall 17 of the corresponding longitudinal lower profile 10 over most of its height, the tab 38 forming a buttress 40 of increasing thickness down to the lower leg 37 (this buttress may optionally be formed by two vertical ribs at the edges of the upper leg 38).

The lower lug 37 is traversed by a screw 41 which may for example comprise a head 42 made of plastic or other material enabling a screwing by hand without tools, the screw 41 being for example screwed into a threaded pin 43 made of stainless steel or other which is sealed in the ground 27 for example by means of a mortar or sealing resin 44. Preferably, the pin 43 is flush with the surface of the ground 27 or more generally has an upper end at a level less than or equal to the level of the ground.

Furthermore, the upper leg 38 of the bracket is traversed by a screw 41 which may be identical or similar to the screw 41 of the lower leg, which screw is screwed into a nut 45 engaged in the lateral groove 18 of the longitudinal lower profile 10.

The nut 45 has a body wider than the opening of the lateral groove 18, which ensures a solid attachment between the upper lug 38 and the profile 10. More particularly, the nut 45 may have a first enlarged portion which penetrates in each channel 32 mentioned above through the slot 33 of this channel, and an enlarged end 45b disposed towards the bottom of the lateral groove 18, that is to say opposite to the opening of said lateral groove.

The screw 41 passes through the opening of the lateral groove 18, so that the fixing of the bracket 36 to the profile 10 does not require drilling of said profile which thus retains all its mechanical characteristics.

Finally, as shown in Figures 1, 4 and 7, the fixed section 4 of the shelter is also fixed to the ground by brackets 36 identical or similar to the brackets previously described and mounted similarly, with the difference that the brackets 36 in question are fixed against the outer side walls 16 of each longitudinal lower profile 10 of this section. The brackets 36 of the fixed section 4 may be optionally 4 in number, respectively fixed towards the front and rear ends of each section 10 of this section.

The screws 41 of the upper legs can be fixed in nuts 45 identical or similar to those described above, said screws 41 passing through a bore 46 formed in the outer side wall 16 of the corresponding section 10.

Note that the nuts 45, as well as the hubs 22, 29 mentioned above, are held in place in the profiles 10 by spacers, (not shown) which can for example be nested in the profiles 10, in a manner known per se.

The brackets 36 of the various sections 2, 3, 4 of the shelter make it possible, on the one hand, to avoid raising the sections of the shelter in the event of strong wind, and on the other hand to breach the shelter sections 2 , 3, 4 avoiding mutual spacing of the side panels 8 of each section in the event of a vertical load on the roof 7 (for example a load due to snow accumulation). These squares work essentially in tension or in compression, but not in torsion between their legs as in the prior art.

Note that all the brackets 36 are easily removable (particularly to move the movable sections 2, 3) without leaving an obstacle on the floor 27 after removal.
