Abstract
Description
La présente invention concerne un dispositif destiné à assurer le déroulement plus la mise en tension d'une toile imperméable, particulièrement sur un plan horizontal et d'augmenter cette tension en rendant la toile légèrement convexe pour permettre une parfaite évacuation des eaux pluviales. The present invention relates to a device intended to ensure the unwinding plus the tensioning of an impermeable fabric, particularly on a horizontal plane and to increase this tension by making the fabric slightly convex to allow perfect evacuation of rainwater.
Les systèmes courants nécessitent un déploiement suivant une pente relativement importante, pour compenser les effets de flèche de la toile et n'éliminent pas les risques de formation de poches d'eau. Current systems require deployment along a relatively steep slope, to compensate for the effects of canvas deflection and do not eliminate the risks of water pockets forming.
Le dispositif représenté sur la figure 1 comporte un enrouleur commandé soit manuellement å l'aide d'un renvoi d'angle démultiplicateur irréversible ou d'un moteur électrique équipé d'un frein électromagnétique. Les deux glissières (2) et (3) rigoureusement symétrique comportent dans leur partie supérieure, un rail (4) assurant le guidage de la barre de traction (5). Cette dernière retenue par la toile (6) côté auvent (7) est tirée vers l'extérieur par un cible (8) passant une première fois dans la double poulie de renvoi (9) puis dans la poulie (10) et une deuxième fois dans la poulie (9) avant de venir s'enrouler dans la poulie (11) solidarisée à l'enrouleur.Les variations de la tension de la toile et du câble en cours de déploiement et en fin de course sont compensées par un diamètre de la poulie (11) approprié et par un ressort (12) maintenant la poulie (10). The device represented in FIG. 1 comprises a reel controlled either manually by means of an irreversible reduction gearbox or an electric motor equipped with an electromagnetic brake. The two rigorously symmetrical slides (2) and (3) have in their upper part, a rail (4) guiding the drawbar (5). The latter retained by the canvas (6) on the awning side (7) is pulled outward by a target (8) passing a first time in the double deflection pulley (9) then in the pulley (10) and a second time in the pulley (9) before being wound up in the pulley (11) secured to the reel. The variations in the tension of the fabric and the cable during deployment and at the end of the race are compensated by a diameter of the pulley (11) suitable and by a spring (12) holding the pulley (10).
L'augmentation de la tension de la toile et sa convexité est assurée par des arches (13) (14) (15) coulissant dans le rail (16) qui comporte un décrochementen pente (17) permettant l'escamotage des arches (13) (14) (15) sous l'enrouleur (1) et la barre de traction (5) en position toile enroulée
Sur la figure 2, la barre de traction (5) a entraîné le chariot (18) jusqu'à l'extrémité de la glissière (2). Par la bielle (19) articulée sur le chariot (18), l'arche (13) s'est trouve entraînée, a gravi la pente (17) puis sur la partie supérieure du rail (16) a entraîné successivement les chariots (20) et (2 1). Ceux-ci par l'intermédiaire des bielles (22) et (23) ont tiré les arches (14) et (15) le long du rail (16) suivant des intervalles réguliers déterminés par les longueurs des bielles.The increase in the tension of the fabric and its convexity is ensured by arches (13) (14) (15) sliding in the rail (16) which includes a sloping notch (17) allowing the retraction of the arches (13) (14) (15) under the reel (1) and the drawbar (5) in the rolled up position
In Figure 2, the drawbar (5) has driven the carriage (18) to the end of the slide (2). By the connecting rod (19) articulated on the carriage (18), the arch (13) has been driven, has climbed the slope (17) then on the upper part of the rail (16) has successively driven the carriages (20 ) and (2 1). These via the connecting rods (22) and (23) pulled the arches (14) and (15) along the rail (16) at regular intervals determined by the lengths of the connecting rods.
Lors du repliement, la barre de traction (5) n'entraîne le chariot (18) qu'après une course déterminée par les butées de la tringle coulissante (24) La bielle (19), solidaire du chariot (18), repousse l'arche (13). Il est a noter que les chariots coulissants dans les rails (4) et (16) sont munis de butées pour éviter toute friction de leurs galets entreeux. When folding, the drawbar (5) drives the carriage (18) only after a stroke determined by the stops of the sliding rod (24) The connecting rod (19), integral with the carriage (18), pushes back the l arch (13). It should be noted that the sliding carriages in the rails (4) and (16) are provided with stops to avoid any friction of their center rollers.
Afin d'obtenir une meilleure convexité de la toile, les arches (13) (14) (15) présentent un bombement vers le haut suffisant pour éviter la formation de plis sur la toile. Par rapport au plan constitué par les parties supérieures de l'enrouleur (1) et de la barre de traction (5), les arches (13) et (15) ont leurs extrémités gauche et droite au.dessus de ce plan. De même, l'arche (14) se trouve aussi plus haute que les arches (13) et (15). Tout cela afin d'assurer l'effet de convexité de la toile. Les parties inférieures des glissières (2) et (3) assurent la canalisation des eaux pluviales s'écoulant des rives latérales de la toile (6) par une pente appropriée vers le carter (25) pourvu d'un orifice d'écoulement (26). In order to obtain better convexity of the canvas, the arches (13) (14) (15) have a bulge upwards sufficient to avoid the formation of folds on the canvas. Relative to the plane formed by the upper parts of the reel (1) and the pull-up bar (5), the arches (13) and (15) have their left and right ends above this plane. Similarly, the arch (14) is also higher than the arches (13) and (15). All this to ensure the convexity effect of the canvas. The lower parts of the slides (2) and (3) ensure the channeling of rainwater flowing from the lateral banks of the fabric (6) by an appropriate slope towards the casing (25) provided with a drainage orifice (26 ).
L'ensemble décrit comporte trois arches mais, peut suivant les dimensions, en comporter davantage; leur mouvement reste toujours commandé suivant les mêmes principes que ceux énoncés plus haut. En position repliée, la barre de traction (5), la toile (6), et l'enrouleur (1) se trouve abrités des intempéries par l'auvent (7). The assembly described comprises three arches but, depending on the dimensions, may include more; their movement is always controlled according to the same principles as those stated above. In the folded position, the drawbar (5), the fabric (6), and the reel (1) is sheltered from the weather by the awning (7).
Lors du fonctionnement de l'ensemble, l'enroulement ou le déroulement de la toile (6) sur son enrouleur (1), ainsi que l'enroulement ou le déroulement du câble (8) sur la poulie (11) provoquent du fait de la superposition des épaisseurs de la toile (6) et du chevauchement des spires du câble (8) des variations de rayon. Ces variations sont compensées par le ressort de mise en tension (12) ainsi que par une tension accrue de la toile provoquée par l'exhaussement des arches (13) (14) (15) en cours de translation sur le double coudage (17) du rail (16) surélevé vers l'avant. During the operation of the assembly, the winding or unwinding of the fabric (6) on its reel (1), as well as the winding or unwinding of the cable (8) on the pulley (11) cause the superimposition of the thicknesses of the fabric (6) and the overlapping of the turns of the cable (8) of the variations in radius. These variations are compensated by the tensioning spring (12) as well as by an increased tension of the fabric caused by the raising of the arches (13) (14) (15) during translation on the double bending (17) of the rail (16) raised forward.
La barre de traction (5) est supportée par le chariot (27) qui se trouve décalé vers l'arrière afin de ménager l'emplacement du charriot (18) pour que l'avant de la barre de traction soit dans l'alignement des deux extrémités extérieures des glissières (2) et (3). The drawbar (5) is supported by the carriage (27) which is offset backwards in order to provide the location of the carriage (18) so that the front of the drawbar is in alignment with the two outer ends of the slides (2) and (3).
Les parois intérieures des rails 4 et 16 sont disposées de façon à interdire toute sortie intempestive des chariots(18) (27) (21) (20) et ceux des glissières (13) (14) (15). Ces ensembles rails-chariots peuvent être ceux du commerce ou sont conçus spécialement, de section rectangulaire avec ouverture latérale pour les liaisons avec les bielles (19) (22) (23), arches (13) (14) (15), tringle (24) et barre de traction (5). Les galets des chariots sont cylindriques. The inner walls of the rails 4 and 16 are arranged so as to prevent any untimely exit of the carriages (18) (27) (21) (20) and those of the slides (13) (14) (15). These rail-carriage assemblies may be those of the trade or are specially designed, of rectangular section with lateral opening for connections with the connecting rods (19) (22) (23), arches (13) (14) (15), rod ( 24) and drawbar (5). The rollers of the carriages are cylindrical.
Des bavettes lestées souples ou des joints brosses pourront offrir une étanchéité aux courants d'air et débris végétaux importants entre la toile (6), les glissières (2) et (3) et l'ensemble auvent-carter (7) et (25). Flexible weighted flaps or brush seals can provide airtightness and significant plant debris between the fabric (6), the slides (2) and (3) and the canopy-casing assembly (7) and (25 ).
Les dimensions de l'ensemble pourront aller de six mètres de largeur d'enroulement à huit mètres de déploiement, le long des glissières (2) et (3) en fonction des composants courants disponibles sur le marché. The dimensions of the assembly can range from six meters of winding width to eight meters of deployment, along the slides (2) and (3) depending on the current components available on the market.
L'ensemble: glissières (2) et (3) - auvent (7) - carter (25) dissimulera au maximum les mécanismes afin d'améliorer l'esthétique du dispositif et la protection des dits mécanismes. The assembly: slides (2) and (3) - awning (7) - casing (25) will conceal the mechanisms as much as possible in order to improve the aesthetics of the device and the protection of said mechanisms.
Les matériaux choisis seront protégés de la corrosion tels que : aluminium, acier traité, plastiques. The materials chosen will be protected from corrosion such as: aluminum, treated steel, plastics.
Pour faciliter la mise en oeuvre sur le chantier, les glissières (2) et (3) et leurs mécanismes seront indépendants et assemblés puis réglés en atelier. Une fois mis en place, il ne restera plus qu'à liaisonner l'enrouleur (1), les arches (13) (14) (15), la barre de traction (5) sur le chariot 27 et la toile (6). Les joues intérieures des glissières (2) et (3), l'auvent (7) et la face avant du carter (25) seront amovibles pour la maintenance de l'installation. To facilitate implementation on site, the slides (2) and (3) and their mechanisms will be independent and assembled and then adjusted in the workshop. Once in place, all that remains is to link the reel (1), the arches (13) (14) (15), the draw bar (5) on the carriage 27 and the fabric (6) . The inner cheeks of the slides (2) and (3), the awning (7) and the front face of the casing (25) will be removable for maintenance of the installation.
Le dispositif selon l'invention permettra une excellente tenue au vent, il est particulièrement destiné à la protection solaire et pluviale de terrasses de bâtiments privés et surtout des terrasses de cafés, restaurants etc... The device according to the invention will allow excellent wind resistance, it is particularly intended for the solar and rain protection of terraces of private buildings and especially terraces of cafes, restaurants etc ...
