Abstract
Description
L'objet de l'invention concerne un dispositif tendeur pour films synthétiques de recouvrement de serres. The object of the invention relates to a tensioning device for synthetic films for covering greenhouses.
il est destiné à permettre une tension régulière les films synthétiques recouvrant les arceau des serres c lamelles ou similaires. it is intended to allow regular tension of the synthetic films covering the arches of greenhouses or lamellas or the like.
Dans les dis?ositifs connlls, on utilisait pour tendre les films de couverture des serres, des accessoires mobiles ou intégrés à l'armature qui ne permettaient pas d1 assurer une tension uniforme poiir résister aux intempéries. In the connlls devices, used to stretch the cover films of greenhouses, mobile accessories or integrated in the frame which did not allow to ensure a uniform tension poiir resist weathering.
De plus, des tendeurs provoquaient souvent des déchirures. In addition, tensioners often caused tears.
Le dispositif suivant l'invention susprime ces inconvénients et permet d'obtenir en même temps qu'un drainage des écoulements sur de très grandes longueurs une tension uniforme des films synthétiques qui sont ainsi parfaitement positionnés et peuvent résister aux intempéries, tcut en assurant une possibilité de reprise de tension sans toucher à l'installation ni utiliser des appareillaoes accessoires. The device according to the invention overcomes these drawbacks and makes it possible to obtain, at the same time as a drainage of the flows over very long lengths, a uniform tension of the synthetic films which are thus perfectly positioned and can resist the weather, tcut by ensuring a possibility voltage recovery without touching the installation or using accessory equipment.
Il est constitué par la combinaison des extrémités de poteaux porteurs d'arceaux profilés en Y avec un élément clipseur niobile dans le plan vertical constituant une gouttière. It is constituted by the combination of the ends of poles carrying Y-shaped arches with a clip element that is not movable in the vertical plane constituting a gutter.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente le tendeur et son support vus en élévation et en coupe.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows the tensioner and its support seen in elevation and in section.
la figure 2 montre a une echelle réduite le fonctionnement du dispositif. Figure 2 shows a reduced scale the operation of the device.
Le poteau porteur 1 est pourvu à son extrémité d'une tonture avec branches 2, 3 formant Y. The support post 1 is provided at its end with a sheer with branches 2, 3 forming Y.
Sur ces secteurs sont fixés les arceaux porteurs 4, 5. On these sectors are fixed the supporting arches 4, 5.
Le tendeur est formé par une surface b constituant une gouttière et dont les parements latéraux 7, 8 sont )référen- tiellement légèrement obliques, mais peuvent être i anale droit. The tensioner is formed by a surface b constituting a gutter and whose lateral facings 7, 8 are) referentially slightly oblique, but can be i anal straight.
A- la partie supérieure de ces parements des clipseurs 9, 10 ou vérrouilleurs retiennent les extrémités des films plastiques 11, 12, des tiges de tensions 13, 14 étant reliées avec articulation à la gouttière 6. A- the upper part of these facings of the clips 9, 10 or locking devices retain the ends of the plastic films 11, 12, tension rods 13, 14 being connected with articulation to the gutter 6.
Des dispositifs de traction réglables 15, 16 manoeu
vrables de l'intérieur permettant d' abaisser l'ensemble 6, 9,
10, flèche A et tendre aux flèches B, C, les films 11, 12.Adjustable traction devices 15, 16 maneuver
from the inside to lower the whole 6, 9,
10, arrow A and tend to arrows B, C, the films 11, 12.
Pour la mise en oeuvre de ce dispositif figure 2, il
y aura des attaches fixes 17, 18 sur les piliers 19,20,
Par contre le tendeur 6 sur le pilier 21 par sa traction flèche A amènera la tension des couvertures 22, 23 sur toutes leurs longueurs placées sur les arceaux 24, 25, 26.For the implementation of this device figure 2, it
there will be fixed fasteners 17, 18 on the pillars 19,20,
On the other hand the tensioner 6 on the pillar 21 by its pulling arrow A will bring the tension of the covers 22, 23 over all their lengths placed on the poles 24, 25, 26.
On arrivera ainsi à réaliser sans plage hétérogène
ni points de traction séparés une tension parfaite des surfaces souples couvrantes 11,12 et autres.We will thus achieve without heterogeneous range
nor separate traction points perfect tension of the flexible covering surfaces 11,12 and others.
L' élément tendeur structure en même temps 1' armature et fait fonction de gouttière assurant l'évacuation entre deux
arceaux.The tensioning element simultaneously structures the frame and functions as a gutter ensuring evacuation between two
hoops.
Toutefois les formes, dimensions et dispositions des
différents éléments pourront varier dans la limite des équivalents
comme d ' ailleurs les matières -utiliser pour leur fabrication,
sans changer pour cela la ccnception générale de l'invention
qui vient d ' être décrite. However the forms, dimensions and arrangements of
different elements may vary within the limit of equivalents
like the materials used for their manufacture,
without changing the general concept of the invention
which has just been described.
