Abstract

The device has a central part (A) with edges cut in circular arc towards an interior of a glass greenhouse. Two triangular lateral parts (B, C) having curved base are assembled on both sides of the central part. The lateral plates are tensioned when an opening frame of the glass greenhouse is opened, and stretched to fold towards the interior.

Description

La présente invention concerne une forme et une découpe de filetsThe present invention relates to a form and a cut of fillets

imperméables aux insectes destinés à être installés sur les ouvrants dits en tabatière rencontrés sur les serres verre maraîchères et horticoles. Ce système peut subir des contraintes  insect-proof to be installed on the so-called snowshoes opening on glasshouse and horticultural greenhouses. This system can be constrained

d'ouverture et de fermeture fréquentes.  frequent opening and closing.

La présence de barres transversales permettant l'ouverture des ouvrants en tabatière rend très difficile la mise en place d'un filet étanche empêchant la pénétration d'insectes nuisibles aux cultures. Le degré de fermeture variable selon la position de l'ouvrant entraîne en effet une tension variable et un pliage difficile des filets.  The presence of transverse bars for opening the openings in snuffbox makes it very difficult to set up a watertight net preventing the penetration of insects harmful to crops. The degree of closing variable according to the position of the opening causes indeed a variable tension and a difficult folding of the nets.

Les filets fragiles doivent alors être tendus vers l'intérieur par des tendeurs afin d'éviter d'être cisaillés au moment de la fermeture. Ils peuvent être disposés en accordéon ce qui rend le système de mise en place encore plus difficile car il faut prévoir un pliage minutieux et précis.  Fragile nets must then be stretched inward by tensioners to avoid being sheared at the time of closing. They can be arranged in accordion which makes the installation system even more difficult because it is necessary to provide a careful and precise folding.

Le dispositif selon l'invention permet de remplacer la pose de tendeurs en assurant une tension naturelle, une bonne étanchéité et un pliage intérieur parfait tout cela par la forme même du filet.  The device according to the invention makes it possible to replace the setting of tensioners by ensuring a natural tension, a good sealing and a perfect internal folding all this by the very shape of the net.

Le filet est ainsi découpé en trois parties É une pièce centrale A, inscrite dans un rectangle, dont les bords latéraux (a3-a4) sont découpés de façon concave (fig. 1) ou selon une ligne brisée concave.  The net is thus cut into three parts A central part A, inscribed in a rectangle, whose side edges (a3-a4) are cut concavely (Figure 1) or in a concave broken line.

É deux pièces latérales B et C s'inscrivant chacune dans un triangle dont la base b3 ou c3 est également concave ou découpée selon une ligne brisée concave (fig. 2) La concavité doit être suffisante pour permettre le passage des barres transversales d'ouverture.  E two side pieces B and C each forming a triangle whose base b3 or c3 is also concave or cut along a concave broken line (figure 2) The concavity must be sufficient to allow the passage of the transverse bars of opening .

Les pièces sont assemblées bord à bord (a3 avec b3 et a4 avec c3) (fig. 3 et 4 et 5) La pièce finale ainsi assemblée est ensuite fixée à l'ouvrant É Les côtés al, b 1 et cl sont fixés sur la partie fixe de l'ouvrant et du toit.  The pieces are assembled edge to edge (a3 with b3 and a4 with c3) (figures 3 and 4 and 5) The final piece thus assembled is then fixed to the opening E The sides al, b 1 and cl are fixed on the fixed part of the opening and the roof.

É Les côtés a2, b2 et c2 sont fixés sur la partie mobile de l'ouvrant (fig. 4 et 5) Lorsque l'ouvrant s'ouvre, les parties B et C de par leur base concave exercent une tension sur la pièce A qui s'incurve 1 o et reste tendue vers l'intérieur de la serre. De même la pièce A exerce une tension sur les parties B et C qui restent également tendues à l'intérieur.  É The sides a2, b2 and c2 are fixed on the movable part of the sash (figures 4 and 5) When the sash opens, the parts B and C by their concave base exert a tension on the piece A which curves 1 o and remains tense towards the inside of the greenhouse. Similarly, the piece A exerts a tension on the parts B and C which also remain stretched inside.

La forme générale assure une forme étanche du filet face à 15 l'ouverture de l'ouvrant.  The general shape ensures a tight shape of the net facing the opening of the opening.

Au moment de la fermeture l'ensemble se plie naturellement en deux et n'encombre pas la fermeture de l'ouvrant.  At the time of closing the assembly folds naturally in two and does not clog the closure of the opening.

Les schémas montrent: É la tenue du filet au moment de l'ouverture maximale de l'ouvrant (fig.7 et 8) É que le filet est tendu par la force de tension 25 qu'exercent les deux découpes. Il ne peut sortir vers l'extérieur. (fig.4) É Il offre une étanchéité totale de l'ouverture É Fermé, il conserve une forme parfaite grâce à une seule pliure et à la tension des pièces (fig. 6, 9 et 10) -3 -  The diagrams show: the holding of the net at the moment of maximum opening of the leaf (FIGS. 7 and 8) that the net is tensioned by the tension force exerted by the two cuts. He can not go out. (fig.4) É It offers a total tightness of the closed opening, it keeps a perfect shape thanks to a single fold and to the tension of the pieces (figs 6, 9 and 10) -3 -
