Description

La prĆ©sente invention concerne une Installation de protection contre le soleil. Plus particuliĆØrement il s'agit d'une installation avec un toit de protection comprenant une ossature porteuse et une pluralitĆ© de lames d'obscurcissement.The present invention relates to a sun protection installation. More particularly, it is an installation with a protective roof comprising a load-bearing framework and a plurality of obscuration blades.

Il est connu de disposer d'un systĆØme de dĆ©placement de la pluralitĆ© de lames. Il est ainsi possible dans une position dĆ©ployĆ©e de couvrir le toit avec la pluralitĆ© de lames d'obscurcissement et dans une position rĆ©tractĆ©e de regrouper les lames pour permettre le passage de la lumiĆØre Ć  travers le toit.It is known to have a system for moving the plurality of blades. It is thus possible in a deployed position to cover the roof with the plurality of obscuration blades and in a retracted position to group the blades to allow the passage of light through the roof.

Il est Ć©galement connu de modifier l'orientation des lames par une rotation des lames autour de leurs axes d'extension.It is also known to modify the orientation of the blades by a rotation of the blades around their extension axes.

Cette disposition permet, en position dĆ©ployĆ©e, de laisser tout de mĆŖme passer une partie de la lumiĆØre Ć  travers le toit selon les besoins de protection contre le soleil.This arrangement allows, in the deployed position, to still let some of the light through the roof according to the need for protection against the sun.

Il a Ć©galement Ć©tĆ© proposĆ© dans le brevet WO 2015/011263 une variante consistant Ć  rĆ©tracter une partie des lames d'un cĆ“tĆ© de l'ossature, et une autre partie des lames de l'autre cĆ“tĆ© de l'ossature, en prĆ©conisant l'utilisation de deux systĆØmes d'entrainement indĆ©pendants pour le dĆ©ploiement de chaque sous-ensemble de la pluralitĆ© des lames.It has also been proposed in the patent WO 2015/011263 a variant of retracting a portion of the blades on one side of the frame, and another part of the blades on the other side of the frame, advocating the use of two independent drive systems for the deployment of each subset of the plurality of blades.

Par dĆ©ploiement on entend dĆ©placement de tout ou partie de la pluralitĆ© de lames visant Ć  les positionner de maniĆØre Ć  ce que chaque lame soit sĆ©parĆ©e de la distance donnĆ©e de la lame attenante.Deployment means moving all or part of the plurality of blades to position them so that each blade is separated from the given distance of the adjacent blade.

La mise en oeuvre de cette variante Ć  deux directions opposĆ©es de dĆ©ploiement, peut s'avĆ©rer dĆ©licate, en posant notamment des problĆØmes de synchronisation lorsqu'on utilise deux systĆØmes d'entraĆ®nement indĆ©pendants pour dĆ©placer les deux sous-ensembles de lames.The implementation of this variant with two opposite directions of deployment, can be tricky, including posing synchronization problems when using two independent drive systems to move the two subsets of blades.

Selon un aspect de l'invention, elle comprend une pluralitƩ d'ƩlƩments de liaison de chariots, chaque ƩlƩment de liaison Ʃtant disposƩ entre deux chariots attenants selon l'une ou l'autre des deux directions de dƩploiement et Ʃtant agencƩ pour limiter la distance sƩparant lesdits deux chariots attenants Ơ une distance donnƩe.According to one aspect of the invention, it comprises a plurality of carriage connecting elements, each connecting element being arranged between two adjacent carriages according to one or other of the two directions of deployment and being arranged to limit the distance separating said two adjacent carriages at a given distance.

Les ƩlƩments de liaison permettent, lors du dƩploiement de la pluralitƩ de lames de conserver une distance constante entre les lames attenantes dƩployƩes.The connecting elements allow, during the deployment of the plurality of blades to maintain a constant distance between the deployed adjoining blades.

L'effet de la limitation de la sĆ©paration de deux chariots attenants Ć  la distance donnĆ©e est alors de rĆ©partir de maniĆØre homogĆØne les rayons de soleil traversant le toit de protection : les lames dĆ©ployĆ©es sont espacĆ©es d'une distance constante tandis que les lames non encore dĆ©ployĆ©es sont regroupĆ©es de maniĆØre resserrĆ©e.The effect of limiting the separation of two carriages adjacent to the given distance is then to distribute homogeneously the sun rays passing through the protective roof: the deployed blades are spaced a constant distance while the blades not yet deployed are grouped together in a narrower manner.

Selon un aspect de l'invention, l'Ć©lĆ©ment de coopĆ©ration avec le guide est agencĆ© pour coopĆ©rer en translation avec le guide selon la direction d'extension du guide et le dispositif de transmission d'un mouvement rotatif Ć  la lame comprend un Ć©lĆ©ment rotatif mĆ©nagĆ© dans l'Ć©lĆ©ment de coopĆ©ration et agencĆ© pour ĆŖtre solidaire en rotation avec le guide autour de la direction d'extension du guide, le dispositif de transmission comprenant en outre un Ć©lĆ©ment de transmission du mouvement de rotation de l'Ć©lĆ©ment rotatif Ć  la lame.According to one aspect of the invention, the element for cooperation with the guide is arranged to cooperate in translation with the guide in the direction of extension of the guide and the device for transmitting a rotary movement to the blade comprises a rotary element. in the element of cooperation and arranged to be integral in rotation with the guide around the direction of extension of the guide, the transmission device further comprising a transmission element of the rotational movement of the rotating member to the blade.

Pour permettre Ć  la pluralitĆ© de chariots 23 d'ĆŖtre dĆ©placĆ©e grĆ¢ce au systĆØme d'entrainement 35, le systĆØme de dĆ©placement 15 comprend une pluralitĆ© d'Ć©lĆ©ments de liaison 45 de chariots 23.To allow the plurality of carriages 23 to be moved by the drive system 35, the displacement system 15 comprises a plurality of linkage elements 45 of carriages 23.

Chaque ƩlƩment de liaison 45 unit deux chariots 23 attenants et est agencƩ pour que la distance sƩparant ces deux chariots 23 attenants soit infƩrieure ou Ʃgale Ơ une distance donnƩe 47.Each connecting element 45 unites two carriages 23 adjacent and is arranged so that the distance separating these two carriages 23 adjacent is less than or equal to a given distance 47.

Selon une premiĆØre variante de l'Ć©lĆ©ment de liaison 45 reprĆ©sentĆ©e aux figures 3bis, 4bis et 7, l'union entre un Ć©lĆ©ment de liaison 45 et un chariot 23 est une liaison selon un degrĆ© de libertĆ©. Il s'agit d'un degrĆ© de libertĆ© rotatif selon un axe transversal Ć  la direction de dĆ©ploiement 19.According to a first variant of the connecting element 45 represented in FIGS. Figures 3a, 4a and 7 , the union between a connecting element 45 and a carriage 23 is a connection according to a degree of freedom. This is a rotational degree of freedom along an axis transverse to the deployment direction 19.

Chaque Ć©lĆ©ment de liaison 45 comprend une premiĆØre partie 45a et une deuxiĆØme partie 45b chacune Ć©tant unis Ć  un chariot 23.

The two parts 45a, 45b are themselves linked in a degree of freedom in rotation also transverse to the deployment direction 19.

Ainsi la distance donnĆ©e 47 entre deux chariots 23 attenants est obtenue lorsque la premiĆØre partie 45a et la deuxiĆØme partie 45b sont alignĆ©es et forment un angle de 180Ā°.Thus the distance 47 between two adjacent carriages 23 is obtained when the first portion 45a and the second portion 45b are aligned and form an angle of 180 Ā°.

Au contraire lorsque la premiĆØre partie 45a et la deuxiĆØme partie 45b prĆ©sentent un angle infĆ©rieur Ć  180Ā°, les chariots 23 attenants se rapprochent. En position rĆ©tractĆ©e, les chariots 23 attenants sont en contact, ce qui dĆ©finit l'angle minimum entre la premiĆØre partie 45a et la deuxiĆØme partie 45b, comme illustrĆ© Ć  la figure 3bis.On the contrary, when the first portion 45a and the second portion 45b have an angle of less than 180 Ā°, the carriages 23 adjoining approach. In the retracted position, the carriages 23 abutting are in contact, which defines the minimum angle between the first portion 45a and the second portion 45b, as illustrated in FIG. figure 3bis .

Les figures 8 Ć  15 prĆ©sentent une seconde variante de l'Ć©lĆ©ment de liaison 45. Selon cette seconde variante, l'Ć©lĆ©ment de liaison 45 est un cĆ¢ble souple 451 passant dans une pluralitĆ© d'orifices 46, chaque chariot 23 comprenant un orifice 46.The Figures 8 to 15 show a second variant of the connecting element 45. According to this second variant, the connecting element 45 is a flexible cable 451 passing through a plurality of orifices 46, each carriage 23 comprising an orifice 46.

Pour maintenir la distance donnĆ©e 47 entre deux chariots 23 attenants en position dĆ©ployĆ©e, le cĆ¢ble souple 451 est fixĆ© Ć  chaque chariot 23 grĆ¢ce Ć  une vis de blocage 48a disposĆ©e transversalement Ć  l'orifice 46 correspondant.To maintain the given distance 47 between two adjacent carriages 23 in the deployed position, the flexible cable 451 is attached to each carriage 23 thanks to a locking screw 48a disposed transversely to the corresponding orifice 46.

Un pas de vis 48b correspondant Ć  la vis de blocage 48a est mĆ©nagĆ© dans chaque chariot 23. De prĆ©fĆ©rence on utilise une vis de blocage 48a sans tĆŖte.A screw thread 48b corresponding to the locking screw 48a is formed in each carriage 23. Preferably a locking screw 48a without a head is used.

Les figures 19 Ć  23 prĆ©sentent une troisiĆØme variante de l'Ć©lĆ©ment de liaison 45. Selon cette variante, l'Ć©lĆ©ment de liaison est une courroie crantĆ©e souple 452 pour assurer la distance entre les chariots grĆ¢ce au pas standard de la courroie. Les chariots sont fixĆ©s Ć  la courroie crantĆ©e souple par l'intermĆ©diaire d'une Ć©querre de fixation 453.The Figures 19 to 23 show a third variant of the connecting element 45. In this variant, the connecting element is a flexible toothed belt 452 to ensure the distance between the carriages with the standard pitch of the belt. The trolleys are attached to the flexible toothed belt via a bracket 453.

Quel que soit le type d'Ć©lĆ©ment de liaison 45 utilisĆ©, la combinaison du systĆØme d'entrainement 35 des chariots 23' ou 23bis' extrĆŖmes et de l'agencement des Ć©lĆ©ments de liaison 45 a pour effet, lors du passage de la position rĆ©tractĆ©e Ć  la position dĆ©ployĆ©e, de maintenir la distance donnĆ©e 47 entre les chariots 23 dĆ©ployĆ©s tandis que les autres chariots 23 sont encore en position rĆ©tractĆ©e. L'effet est donc de rĆ©partir de maniĆØre homogĆØne les rayons de soleil traversant le toit de protection, l'Ć©cart entre chariots 23 dĆ©ployĆ©s Ć©tant constant.Whatever the type of connecting element 45 used, the combination of the driving system 35 of the carriages 23 'or 23bis' extreme and the arrangement of the connecting elements 45 has the effect, during the passage of the retracted position in the deployed position, maintain the given distance 47 between the carriages 23 deployed while the other carriages 23 are still in the retracted position. The effect is therefore to evenly distribute the sunlight passing through the protective roof, the distance between carriages 23 deployed being constant.

Comme illustrƩ aux figures 16 et 17, chaque chariot 23 de dƩplacement comprend un ƩlƩment d'accrochage 49 au rail 17 correspondant. Selon la variante reprƩsentƩe sur ces figures, l'ƩlƩment d'accrochage 49 comprend deux patins rotatifs 51 disposƩs de part et d'autre du rail 17.As illustrated in Figures 16 and 17 each carriage 23 comprises a hooking element 49 to the corresponding rail 17. According to the variant shown in these figures, the hooking element 49 comprises two rotary pads 51 arranged on either side of the rail 17.

Comme illustrĆ© aux figures 8 Ć  10 et selon une deuxiĆØme variante l'Ć©lĆ©ment d'accrochage 49 comprend une encoche 53 coopĆ©rant par complĆ©mentaritĆ© de forme avec le rail 17 correspondant et un patin de glissement 55 coopĆ©rant Ć©galement avec le rail 17.As illustrated in Figures 8 to 10 and according to a second variant, the hooking element 49 comprises a notch 53 cooperating in complementary form with the corresponding rail 17 and a sliding shoe 55 also cooperating with the rail 17.

Selon une troisiĆØme variante des chariots de dĆ©placement, illustrĆ©e figures 19 Ć  23, l'Ć©lĆ©ment d'accrochage 49 au rail 17 est un patin de glissement 551 coopĆ©rant par complĆ©mentaritĆ© de forme avec une bande de glissement 552 avec guidage latĆ©ral 553.According to a third variant of the travel trolleys, illustrated Figures 19 to 23 , the attachment element 49 to the rail 17 is a sliding shoe 551 cooperating in complementary form with a sliding strip 552 with lateral guidance 553.

Le patin de glissement 55, 551 est rĆ©alisĆ© dans un matĆ©riau caractĆ©risĆ© par un faible coefficient de frottement, de prĆ©fĆ©rence infĆ©rieur Ć  0,34, et une trĆØs bonne rĆ©sistance Ć  l'abrasion, tel qu'un polyoxylomĆ©thylĆØne, ou POM, par exemple ; la bande de glissement correspondante est rĆ©alisĆ©e dans un matĆ©riau Ć  grand pouvoir anti-adhĆ©sif et faible coefficient de frottement, de prĆ©fĆ©rence infĆ©rieur Ć  0.1, afin de faciliter le dĆ©placement en minimisant les frottements, et les risques de blocages intempestifs ; Ć  cet effet, on pourra notamment utiliser un polytĆ©trafluoroĆ©thylĆØne, tel que le TEFLON par exemple.The sliding shoe 55, 551 is made of a material characterized by a low coefficient of friction, preferably less than 0.34, and a very good resistance to abrasion, such as a polyoxylomethylene, or POM, for example; the corresponding sliding strip is made of a material with high anti-adhesive and low coefficient of friction, preferably less than 0.1, in order to facilitate the movement by minimizing the friction, and the risk of untimely blockages; for this purpose, it may in particular use a polytetrafluoroethylene, such as TEFLON for example.

Comme illustrƩ Ơ la figure 18, le profil du rail 17 peut prƩsenter une forme adaptƩe pour qu'un capot de protection 57 soit disposƩ dessus. Le rail 17 peut Ʃgalement prƩsenter une extension infƩrieure 59 pour divers besoins d'accrochage propre Ơ l'installation et non dƩtaillƩs dans le prƩsent texte.As illustrated in figure 18 , the profile of the rail 17 may have a shape adapted for a protective cover 57 is arranged on it. The rail 17 may also have a lower extension 59 for various attachment requirements specific to the installation and not detailed in this text.

Selon la variante avec patin de glissement 551 et bande de glissement 552, la bande de glissement 552 est intƩgrƩe directement dans la structure qui permet de crƩer un guidage latƩral, comme cela est illustrƩ Ơ la figure 22.According to the variant with sliding pad 551 and sliding strip 552, the sliding strip 552 is integrated directly into the structure which makes it possible to create lateral guidance, as illustrated in FIG. figure 22 .

A la figure 18, on a Ć©galement reprĆ©sentĆ© le chariot 23' extrĆŖme comprenant une fixation 43 avec la courroie 37. Les autres chariots 23 prĆ©sentent une gĆ©omĆ©trie similaire mais sans fixation Ć  la courroie 37.To the figure 18 the carriage 23 'having an attachment 43 with the belt 37 is also shown. The other carriages 23 have a similar geometry but without attachment to the belt 37.

Comme illustrĆ© plus particuliĆØrement aux figures 8 et 9, chaque chariot 23 situĆ© du cĆ“tĆ© du guide 29 comprend un dispositif de transmission 61 d'un mouvement rotatif du guide 29 Ć  la lame 11 correspondante.As illustrated more particularly in Figures 8 and 9 , each carriage 23 located on the side of the guide 29 comprises a device 61 for transmitting a rotary movement of the guide 29 to the corresponding blade 11.

Le dispositif de transmission 61 comprend un ƩlƩment rotatif 63 mƩnagƩ dans un ƩlƩment de coopƩration 65 avec le guide du chariot 23. L'ƩlƩment rotatif 63 est solidaire en rotation avec le guide 29.The transmission device 61 comprises a rotary element 63 formed in a cooperation element 65 with the guide of the carriage 23. The rotary element 63 is integral in rotation with the guide 29.

L'ƩlƩment rotatif 63 prƩsente une surface de coopƩration 67 avec le guide 29 par complƩmentaritƩ de forme. La surface de coopƩration 67 prƩsente une rainure 69 de profil constant selon la direction d'extension du guide 29.The rotary member 63 has a cooperating surface 67 with the guide 29 by complementary shape. The cooperation surface 67 has a groove 69 of constant profile in the direction of extension of the guide 29.

Le guide 29 prĆ©sente une nervure 71 de forme complĆ©mentaire Ć  la rainure 69 de l'Ć©lĆ©ment rotatif 63. Ainsi la coopĆ©ration entre la rainure 69 et la nervure 71 permet une solidarisation en rotation du guide 29 et de l'Ć©lĆ©ment rotatif 63. La nervure peut par exemple prendre une forme carrĆ©e mĆ¢le, coopĆ©rant avec une rainure de forme carrĆ©e femelle.The guide 29 has a rib 71 of complementary shape to the groove 69 of the rotary member 63. Thus the cooperation between the groove 69 and the rib 71 allows a rotational connection of the guide 29 and the rotary member 63. The rib can for example take a male square shape, cooperating with a female square-shaped groove.

Toutefois, le profil identique de la rainure 69 et de la nervure 71 selon la direction d'extension du guide 29 permet un coulissement axial de l'ƩlƩment rotatif 63 par rapport au guide 29. Chaque chariot 23 situƩ du cƓtƩ du guide 29 est ainsi apte Ơ coulisser selon la direction de dƩploiement 19 par rapport au rail 17 correspondant et au guide 29.However, the identical profile of the groove 69 and the rib 71 in the direction of extension of the guide 29 allows axial sliding of the rotary member 63 relative to the guide 29. Each carriage 23 located on the side of the guide 29 is thus slidable in the direction of deployment 19 relative to the corresponding rail 17 and the guide 29.

L'Ć©lĆ©ment rotatif 63 comprend Ć©galement une surface d'entrainement 73 externe prĆ©sentant une forme de cannelure hĆ©licoĆÆdale 74 orientĆ©e selon l'axe d'extension du guide 29.The rotary element 63 also comprises an external drive surface 73 having a helical corrugation shape 74 oriented along the axis of extension of the guide 29.

Le dispositif de transmission 61 comprend en outre un ƩlƩment de transmission 75 agencƩ pour coopƩrer avec l'ƩlƩment rotatif 69. L'ƩlƩment de transmission 75 est destinƩ Ơ transmettre le mouvement de rotation de l'ƩlƩment rotatif 69 Ơ la lame 11 correspondante.The transmission device 61 further comprises a transmission element 75 arranged to cooperate with the rotary element 69. The transmission element 75 is intended to transmit the rotational movement of the rotary element 69 to the corresponding blade 11.

Pour ce faire l'ƩlƩment de transmission 75 prƩsente une surface complƩmentaire 77 Ơ la surface d'entrainement 73 de l'ƩlƩment rotatif 69. Cette surface complƩmentaire 77 se prƩsente sous la forme d'une denture circulaire 78.To do this, the transmission element 75 has a complementary surface 77 to the driving surface 73 of the rotary element 69. This complementary surface 77 is in the form of a circular toothing 78.

La cannelure hĆ©licoĆÆdale 74 et la denture circulaire 78 coopĆØrent et forment un systĆØme Ć  engrenages. La denture circulaire 74 est solidaire Ć  l'arbre 25 du chariot 23 correspondant.The helical groove 74 and the circular toothing 78 cooperate and form a gear system. The circular toothing 74 is integral with the shaft 25 of the carriage 23 corresponding.

Ainsi la rotation de la cannelure hĆ©licoĆÆdale 74 provoquĆ©e par la rotation du guide 29 engendre la rotation des lames 11.Thus the rotation of the helical groove 74 caused by the rotation of the guide 29 causes the blades 11 to rotate.

Il est Ơ remarquer qu'une lame 11 est reliƩe d'un cƓtƩ Ơ un chariot 23 comprenant un dispositif de transmission 61 et de l'autre cƓtƩ Ơ un chariot 23 n'en comprenant pas. Ainsi les chariots 23 situƩs du cƓtƩ opposƩ au guide 29 ont un arbre 25 qui est libre en rotation autour de son axe.It should be noted that a blade 11 is connected on one side to a carriage 23 comprising a transmission device 61 and on the other side to a carriage 23 which does not include it. Thus the carriages 23 located on the side opposite the guide 29 have a shaft 25 which is free to rotate about its axis.

Les dispositions dĆ©taillĆ©es ci-avant permettent de rĆ©aliser le passage de la position rĆ©tractĆ©e Ć  la position dĆ©ployĆ©e des lames 11 et inversement de maniĆØre totalement indĆ©pendante Ć  l'orientation des lames par rapport Ć  leur direction d'extension.The arrangements detailed above make it possible to carry out the transition from the retracted position to the deployed position of the blades 11 and vice versa completely independently of the orientation of the blades with respect to their direction of extension.

Le systĆØme de dĆ©placement 15 de l'installation de protection 1 contre le soleil permet donc de maniĆØre simple et fiable d'adapter la protection voulue contre le soleil soit en inclinant les lames 11 soit en les faisant coulisser le long des rails 11, selon deux directions opposĆ©es (19, 19bis) et de faƧon symĆ©trique par rapport Ć  l'axe central du toit de protection (3)The displacement system 15 of the protection system 1 against the sun thus makes it possible in a simple and reliable way to adapt the desired protection against the sun either by tilting the blades 11 or by sliding them along the rails 11, according to two opposite directions (19, 19a) and symmetrically with respect to the central axis of the protective roof (3)

Comme il va de soi, l'invention ne se limite pas Ơ la seule forme d'exƩcution de cette installation de protection contre le soleil, dƩcrite ci-dessus Ơ titre d'exemple, elle en embrasse au contraire toutes les variantes de rƩalisation.As goes without saying, the invention is not limited to the sole embodiment of this sun protection installation, described above as an example, it encompasses all the variants.
