Abstract

The frame profile for a pool cover has multiple tubes connected together and tensioned into a rigid structure by a central cable running through them. The central profile can have a longitudinal hole which receives the cable in its lower section prior to tensioning of the cable.

Description

Profil porteurmulti-tubulaire, cintr6,
à rainures lat6rales, pour structures fixes ou mobiles
La présente invention apporte des avancées technologiques dans la réalisation de structures légères, fixes ou découvrables de toutes portées, destinées à couvrir toute surface qui de part sa vocation doit s'adapter à la saison ou à la climatologie ambiante
(piscine, tennis, restaurant, salle des ftes etc...).Multi-tubular support profile, curved 6,
with lateral grooves, for fixed or mobile structures
The present invention provides technological advances in the production of light, fixed or discoverable structures of all spans, intended to cover any surface which, due to its vocation, must adapt to the season or the ambient climatology.
(swimming pool, tennis, restaurant, party room etc ...).

Dans le cas de structures découvrables des modules concentriques viennent s'emboiter les un sous les autres pour laisser instantanément à 1'air fibre un espace préablement couvert.In the case of discoverable structures, concentric modules fit one under the other to instantly leave the fiber air a previously covered space.

L'éliment principal constitutif de ces modules mobiles (ou fixes), est un profilé aluminium cintré en forme d'arceau ou demi-arceau qui constitue l'armature porteuse de la structure.The main food constituting these mobile (or fixed) modules is a curved aluminum profile in the form of a hoop or half-hoop which constitutes the supporting frame of the structure.

Les avancées technologiques générées par la présente invention concernent ce profilé. The technological advances generated by the present invention relate to this profile.

On connaît par les documents FR 2 599 118-AI, FR 2 627 530-A1 et EP 0 633 370 Al divers types de profites appelés à remplir cette fonction et dont chacun constitue une évolution technologique du précédent.We know from documents FR 2 599 118-AI, FR 2 627 530-A1 and EP 0 633 370 A1 various types of profits called upon to fulfill this function and each of which constitutes a technological evolution of the previous one.

En effet le document FR 2 599 118-A I présente un profilé étudié en vue de la réalisation de structures légères. Il est tubulaire, rond à t'extérieur et possède une âme rectangulaire. Il est pourvu à t'extérieur. sur ses quatre quarts de secteur, de rainures de moindre résistance permettant de dégager ainsi les quatre zones d'insertion des panneaux de remplissage. Bien que remplissant déjà les principales fonctions recherchées par ce type de profité. sa conception et sa forme différent totalement des produits postérieurs.In fact the document FR 2 599 118-A I presents a profile studied with a view to the production of light structures. It is tubular, round on the outside and has a rectangular core. It is provided outside. on its four quarters of the sector, grooves of less resistance allowing thus to release the four zones of insertion of the filling panels. Although already fulfilling the main functions sought by this type of profit. its design and shape are totally different from later products.

On connaît par le document FR 2 627 530-AI un profilé simple à corps creux central porteur et tubulaire de forme rectangulaire. Ce corps creux est entouré sur ses faces latérales d'ailettes symétriques permettant de recevoir les plaques de couverture. Mais ce simple corps creux central présente des risques de vrillage dés que la portée augmente.Document FR 2 627 530-AI discloses a simple profile with a central support hollow body and tubular of rectangular shape. This hollow body is surrounded on its lateral faces by symmetrical fins making it possible to receive the cover plates. But this simple central hollow body presents risks of twisting as soon as the range increases.

On connaît aussi par le document EP 0 633 370-Al une évolution du profité précédent
Le corps creux central est remplacé par un corps massif en forme de fourche inversée. encadrée par deux corps creux latéraux qui servent pour partie d'éléments constitutifs des rainures supérieures et inférieures permettant d'insérer les panneaux de fermeture.Document EP 0 633 370-A1 also shows an evolution of the preceding profit
The central hollow body is replaced by a massive body in the form of an inverted fork. framed by two lateral hollow bodies which serve in part as constituent elements of the upper and lower grooves for inserting the closure panels.

Ces deux corps creux latéraux apportent une résistance accrue au vrillage.These two lateral hollow bodies provide increased resistance to twisting.

Mais avec ce procédé, il est nécessaire de percer la paroi centrale ainsi que les parois latérales des corps creux afin de faire passer les entretoises d'union des arceaux et de contreventement de la structure. Cette opération de perçage outre l'affaiblissement de 1'arceau porteur présente les deux désavantages suivants :
Tout changement ou adjonction d'entretoise exige le démontage total de la structure.But with this method, it is necessary to pierce the central wall as well as the side walls of the hollow bodies in order to pass the struts for joining the arches and bracing the structure. This drilling operation, in addition to weakening the carrying bar, has the following two disadvantages:
Any change or addition of a spacer requires total disassembly of the structure.

Un perçage effectué légèrement trop bas dans les corps creux, vient entamer la paroi du fond de la fourche et la vis de fixation de 1'entretoise ne peut plus remplir son rôle de blocage
Le but que s'est fixe le demandeur dans le cadre de cette invention est de proposer un profite reprenant certaines caractéristiques des profilés décrits dans les documents ci-dessus et notamment EP 0 633 370-Al, en ce qu'il se compose d'un corps porteur encadré de deux corps creux et de deux jeux d'ailettes symétriques destinés à recevoir les panneaux de remplissage inter-arceaux, mais en apportant certaines améliorations essentielles par rapport aux documents cités précédemment.A hole made slightly too low in the hollow bodies, starts the wall of the bottom of the fork and the fixing screw of the spacer can no longer fulfill its blocking role
The aim which the applicant has set for this invention is to provide a profit incorporating certain characteristics of the profiles described in the above documents and in particular EP 0 633 370-A1, in that it consists of a carrier body framed by two hollow bodies and two sets of symmetrical fins intended to receive the inter-arch filling panels, but providing certain essential improvements compared to the documents cited above.

Selon 1'invention, le corps central porteur (1) peut se présenter sous deux formes :
-Plein, mais comportant Un ou plusieurs trous longitudinaux (Fig 1 & Fig Ibis)
-Tubulaire de forme rectangulaire (Fig 2)
Dans les deux cas, les trous longitudinaux ou la cage rectangulaire servent de réservation pour le passage de Un ou plusieurs cables d'acier.According to the invention, the central carrying body (1) can take two forms:
-Full, but with one or more longitudinal holes (Fig 1 & Fig Ibis)
-Tubular rectangular shape (Fig 2)
In both cases, the longitudinal holes or the rectangular cage serve as a reservation for the passage of one or more steel cables.

Ces cables en acier, une fois mis en traction dans le coeur du profilé aluminium, creent une poutre composite post-contrainte aux caractéristiques mécaniques sans communes mesures par rapport à un simple profilé de mme section ou de mme inertie.These steel cables, once put in tension in the core of the aluminum profile, create a post-stressed composite beam with mechanical characteristics without common measurements compared to a simple profile of the same section or the same inertia.

-Dans le cas du corps plein central, le cable passant dans le trou"Intérieur"du profilé sert à compenser les efforts de traction vers l'intérieur du profilé. (Fig I). -In the case of the central solid body, the cable passing through the "inside" hole of the profile is used to compensate for the traction forces towards the inside of the profile. (Fig I).

De mme le cable passant dans le trou"Extérieur"du profilé sert à compenser les efforts de traction vers t'extérieur du profilé.Likewise, the cable passing through the "outside" hole of the profile serves to compensate for the tensile forces towards the outside of the profile.

La combinaison des deux trous permet ainsi de compenser A LA FOIS les effets de traction vers l'intérieur ET 1'exterieur (Figlbis), mais nécessite l'emploi de deux cables.The combination of the two holes thus makes it possible to compensate BOTH the effects of traction towards the interior AND the exterior (Figlbis), but requires the use of two cables.

-Dans le cas du corps central tubulaire rectangulaire (Fig 2), UN seul cable guidé par des entretoises (10) insérées dans le profilé et lui faisant effectuer un trajet sinusoïdal correspondant aux zones de traction, permettra de remplacer avantageusement les deux cables précédents
L'homme de métier pourra, sans pour autant sortir du cadre de l'invention, changer la position ou le nombre de cables dans le cas des figures 1 & lbis, la sinusoïde dans le cas de figure n 2 ainsi que faire varier les forces de traction appliquées au (x) cables.-In the case of the rectangular tubular central body (Fig 2), ONE single cable guided by spacers (10) inserted in the profile and making it perform a sinusoidal path corresponding to the traction zones, will advantageously replace the two previous cables
A person skilled in the art may, without departing from the scope of the invention, change the position or the number of cables in the case of FIGS. 1 & lbis, the sinusoid in the case of FIG. 2 as well as vary the forces. of tension applied to (x) cables.

L'homme de métier pourra aussi, sans pour autant sortir du cadre de l'invention, prévoir d'insérer des cables dans les ailettes latérales (8 & 8bis) (9 & 9bis) hors corps central (Fig3).Those skilled in the art may also, without departing from the scope of the invention, plan to insert cables into the lateral fins (8 & 8bis) (9 & 9bis) outside the central body (Fig3).

Le principe mme de création d'une poutre composite post-contrainte (ou pré-contrainte) par adjonction de cable (s) destiné (s) à tre tendu (s) dans le corps d'un profilé cintré ou pas, dans le but d'accroitre sa résistance reste à l'évidence dans le cadre de cette invention.The very principle of creating a post-stressed (or pre-stressed) composite beam by adding cable (s) intended to be stretched (s) in the body of a curved profile or not, for the purpose increasing its resistance is obviously within the scope of this invention.

Toujours selon l'invention, le corps central, plein ou tubulaire, est encadré par deux corps creux. Le demandeur a déjà fait remarquer les inconvénients qu'il y avait à percer ces corps creux, ainsi d'ailleurs que le corps central, pour faire passer les entretoises de contreventement (Doc EP 0 633 370-Al)
Afin de pallier à ces inconvénients, les deux corps creux (2 & 2bis) latéraux adjacents au corps central sont pourvus sur leur face extérieure d'une rainure (3 & 3bis) destinee å recevoir des inserts coulissants (FigS). Chaque insert est composé d'une partie coulissant dans la rainure et d'un appendice tubulaire (12) permettant l'union avec 1'entretoise (13) correspondante.Still according to the invention, the central body, full or tubular, is surrounded by two hollow bodies. The applicant has already pointed out the drawbacks of piercing these hollow bodies, as well as the central body, to pass the bracing struts (Doc EP 0 633 370-Al)
In order to overcome these drawbacks, the two lateral hollow bodies (2 & 2bis) adjacent to the central body are provided on their outer face with a groove (3 & 3bis) intended to receive sliding inserts (FigS). Each insert is composed of a part sliding in the groove and a tubular appendage (12) allowing union with the corresponding spacer (13).

Une vis à pointeau (I 1) permet de bloquer chaque insert à sa place dans la rainure du profilé
Un simple boulon traversant (14) assure une liaison parfaite insert-entretoise. A needle screw (I 1) allows each insert to be locked in place in the profile groove
A simple through bolt (14) ensures a perfect insert-spacer connection.

Chaque entretoise peut donc tre rendue mobile tout le long des rainures latérales 3 et 3bis par simple dévissage de la vis à pointeau. Pour ajouter, postérieurement au montage, une ou plusieurs entretoises, il suffit donc d'ajouter le nombre d'inserts nécessaires par le biai d'un évidement au pied de chaque arceau et de repositionner les entretoises déjà en place.Each spacer can therefore be made mobile all along the lateral grooves 3 and 3bis by simply unscrewing the needle screw. To add, after assembly, one or more spacers, it suffices to add the number of inserts required by the biai of a recess at the foot of each hoop and to reposition the spacers already in place.

Pour changer une entretoise (chute de branche d'arbre, etc..) il suffit de la désolidariser de ses deux inserts d'extrémité et de la remplacer.To change a spacer (falling tree branch, etc.), just separate it from its two end inserts and replace it.

Ces deux opérations, extremement lourdes dans le cas d'entretoises traversant les corps creux, sont désormais instantanées, grâce à l'invention du demandeur.These two operations, extremely heavy in the case of spacers passing through the hollow bodies, are now instantaneous, thanks to the invention of the applicant.

Toujours selon l'invention, la composition des arceaux porteurs en sous-éléments assemblés entre eux apporte novation par rapport aux produits existants.Still according to the invention, the composition of the supporting arches in sub-elements assembled together brings innovation compared to existing products.

Les arceaux sont de préférence réalisés, dans les autres procédés, par assemblage de deux demi-arceaux. On connaît par les documents FR 2 627 530-Al et EP 0 633 370-Al tout l'intért que présente une forme semi-elliptique par rapport à une forme demi-circulaire :
En effet cette forme permet de dégager sur les bords de la structure une hauteur utile c'est à dire"habitable"bien supérieure à ce (le offerte par une forme demi-circulaire.The hoops are preferably produced, in the other methods, by assembling two half-hoops. We know from documents FR 2 627 530-A1 and EP 0 633 370-A1 all the advantages of a semi-elliptical shape compared to a semi-circular shape:
Indeed this shape allows to release on the edges of the structure a useful height that is to say "habitable" much greater than that (the offered by a semicircular shape.

Par contre un arceau semi-elGptique est formé par deux rayons de courbure. (RI & R2)
Un arceau est donc constitué par la succession de (RI + R2) + (R2 + Rt) et par conséquent un demi-arceau par RI + R2. Tout homme du métier de cintreur sait qu'au changement de rayon un écrasement se produit dans le profilé.On the other hand, a semi-elGptic arch is formed by two radii of curvature. (RI & R2)
An arch is therefore constituted by the succession of (RI + R2) + (R2 + Rt) and therefore a half-arch by RI + R2. Anyone skilled in the art of bending knows that when the radius is changed, a crushing occurs in the profile.

Le demandeur, dans le cadre de cette invention, propose de partager 1'arceau en Trois éléments minimun (RI + R2 + RI) (Fig 4) chaque élément ne possédant qu'UN SEUL rayon de courbure. Les problèmes d'écrasement sont supprimés et le cintrage en est simplifié.The applicant, in the context of this invention, proposes to divide the arch into three minimum elements (RI + R2 + RI) (Fig 4) each element having only ONE SINGLE radius of curvature. The crushing problems are eliminated and the bending is simplified.

Par extension de cet aspect de l'invention, on pourra garder constant le rayon RI et augmenter seulement R2 (fig 4bis) en fonction de la portee. Ceci permet une pré-fabrication des éléments RI pour une meilleure productivité et des délais de livraison plus courts.By extension of this aspect of the invention, the radius RI can be kept constant and only increase R2 (fig 4bis) depending on the range. This allows RI elements to be pre-manufactured for better productivity and shorter delivery times.

En conclusion ce profilé présente TROIS aspects totalement novateurs :
-La possibilité d'insertion d'un ou plusieurs cables d'acier afin d'augmenter la résistance.In conclusion, this profile presents THREE totally innovative aspects:
-The possibility of inserting one or more steel cables to increase the resistance.

-Deux rainures latérales permettant une union facile et évolutive Arceau/Entretoise. -Two lateral grooves allowing an easy and progressive union of the Arch / Spacer.

-Une composition de 1'arceau (R ! constant/R2 variabte/R ! constant) permettant un cintrage facile et une préfabrication des eléments RI.  - A composition of the hoop (R! Constant / R2 variabte / R! Constant) allowing easy bending and prefabrication of RI elements.

En outre le profilé comporte symétriquement de part et d'autre du corps central :
-Deux rainures au-dessus des corps creux recevant la plaque alvéolaire de toiture. (4 & 4 bis)
-Deux rainures en-dessous des corps creux pour les plaques latérales relevables. (5 & 5bis)
Au-dessus du corps central et dans l'axe A-A'une rainure (6) reçoit un joint destiné à assurer ltétanchéité avec l'arceau supérieur dans le cas de structure mobile.In addition, the profile has symmetrically on either side of the central body:
-Two grooves above the hollow bodies receiving the alveolar roofing plate. (4 & 4a)
-Two grooves below the hollow bodies for the liftable side plates. (5 & 5bis)
Above the central body and in the axis A-A ′ a groove (6) receives a seal intended to ensure sealing with the upper arch in the case of a mobile structure.

En-dessous du corps central et dans l'axe A-A'une rainure (7) reçoit les panneaux de fermeture verticale des fonds de la structure. Dans le cas des arceaux intermédiaires, cette rainure est avantageusement obturée par un joint de couleur servant d'élément décoratif. (non représente)
De meme, les rainures latérales recevant l'insert d'union"Profilé/Entretoise"sont pourvues entre chaque entretoise d'un joint de couleur servant avantageusement d'élément décoratif Below the central body and in the axis A-A 'a groove (7) receives the vertical closure panels of the bottom of the structure. In the case of intermediate arches, this groove is advantageously closed by a colored joint serving as a decorative element. (not shown)
Likewise, the lateral grooves receiving the "Profile / Spacer" union insert are provided between each spacer with a colored seal advantageously serving as a decorative element.
