Abstract

The edges of the film or films 8 and 9 acting as flexible covers are secured between, on the one hand, the walls of a seat 6 formed by a channel 4 and 5 formed in each of the two securing elements 2 and 3 and, on the other hand, an intermediate member 7, the whole assembly being clamped together by a sleeve 10 acting like a vice, which slides along the two securing elements 2 and 3 and which is positioned along these at regular intervals. The invention applies particularly to the covering of greenhouses, agricultural buildings and other spaces needing to be covered with a flexible material.

Description

L'invention concerne un dispositif de maintien et de blocage d'une couverture destinée à l'équipement, notamment de serres ou autres espaces couverts. The invention relates to a device for holding and blocking a cover intended for equipment, in particular greenhouses or other covered spaces.

Plusieurs problèmes se posent au niveau de la conception et de la réalisation de tels dispositifs. Une technique connue pour le montage notamment des vitrages de serres solaires consiste à enrouler la couverture de plastique autour d'une baguette et à clouer le tout. Une autre variante consiste à coincer le ou les films,s'ils sont au nombre de deux, à l'aide d'une entretoise s'encastrant dans un logement prévu à cet effet dans le longeron support. Several problems arise in the design and construction of such devices. A known technique for mounting, in particular, glazing for solar greenhouses consists in wrapping the plastic cover around a rod and nailing everything. Another variant consists in wedging the film or films, if they are two in number, using a spacer fitting into a housing provided for this purpose in the support beam.

Des difficultés surgissent -d'une part au niveau de la mise en place et de la folidarisation des différents éléments entre eux pour assurer ce coincement, et, d'autre part, au niveau du scellement au sol ou de 15amarrage de l'ensemble. Difficulties arise on the one hand at the level of the positioning and the joining of the different elements together to ensure this wedging, and on the other hand at the level of the sealing on the ground or of mooring of the assembly.

La présente invention a pour but de pallier ces inconvénients, et concerne un dispositif de blocage d'une couverture se présentant notamment sous la forme d'un film plastique à une ou plusieurs couches qui permet une mise en place facile de ce film, et un serrage des éléments assurant un coincement qui soit efficace uniformément réparti sur au moins une longueur déterminée ainsi que réglable à la demande. The object of the present invention is to overcome these drawbacks, and relates to a device for blocking a cover, in particular in the form of a plastic film with one or more layers which allows this film to be put in place easily, and a tightening of the elements ensuring a wedging which is effective uniformly distributed over at least a determined length as well as adjustable on demand.

Elle concerne plus précisément un tel dispositif de blocage d'une couverture constitué d'au moins un film souple notamment destiné à recouvrir une serre , caractérisé en ce qu'il comporte deux éléments de blocage constitués par deux longerons comportant chacun une rainure destinée à se faire face pour former un logement, les bords d'au moins un film étant bloqué entre la paroie de ce logement et le contour d'une entretoise introduite dans ce logement, ces deux éléments de blocage etcetteentretoise étant alors pris en charge, à intervalles réguliers, le long des longerons par un manchon jouant une fonction d'étau, capable de serrer,en applicant une pression,l'un contre l'autre les deux éléments de blocage. More specifically, it relates to such a device for blocking a cover made up of at least one flexible film, in particular intended to cover a greenhouse, characterized in that it comprises two blocking elements constituted by two longitudinal members each comprising a groove intended to be face to form a housing, the edges of at least one film being blocked between the wall of this housing and the outline of a spacer inserted in this housing, these two locking elements and this spacer being then taken care of, at regular intervals , along the side members by a sleeve acting as a vice, capable of tightening, by applying pressure, one against the other the two locking elements.

L'invention sera mieux comprise à l'aide des explications qui vont suivre et de la figure unique jointe qui illustre schématiquement les éléments essentiels constituant un dispositif conforme à l'invention. The invention will be better understood with the aid of the explanations which follow and of the single attached figure which schematically illustrates the essential elements constituting a device in accordance with the invention.

Comme le montre la figure 1, un dispositif de blocage 1, conforme à l'invention, comporte deux éléments de blocage 2 et 3 se présentant sous le forme de deux longerons 22 et 33 destinés à être accolés l'un contre l'autre, et à coopérer avec une entretoise 7. Ces longerons 22 et 33 comportent chacun une rainure 4 et 5 qui délimite un logement 6.dans lequel est introduite l'entretoise 7. Selon une caractéristique de l'invention, le bord d'au moins un film 8 devant servir de couverture est plaqué contre les paroies de ce logement 6 et s'y trouve emprisonné entre ces paroies et l'entretoise 7.Dans le cas où deux films 8 et 9 sont mis en place, les extrémités a et b respectives des bords emprisonnés dans le meme logement 6 sont ou bien laissées libres(voir figure) ou bien rendues solidaires l'une de l'autre. I1 peut s'agir d'une couture ou d'une soudure illustrée au moyen d'un pointillé, celle-ci pouvant éventuellement constituérun ourlet 40 dans lequel on enfile l'entretoise 7. As shown in FIG. 1, a blocking device 1, in accordance with the invention, comprises two blocking elements 2 and 3 in the form of two longitudinal members 22 and 33 intended to be joined against one another, and to cooperate with a spacer 7. These beams 22 and 33 each have a groove 4 and 5 which delimits a housing 6.in which is inserted the spacer 7. According to a characteristic of the invention, the edge of at least one film 8 to serve as a cover is pressed against the walls of this housing 6 and is trapped there between these walls and the spacer 7. In the case where two films 8 and 9 are put in place, the ends a and b respectively edges trapped in the same housing 6 are either left free (see figure) or made integral with one another. It can be a seam or a weld illustrated by means of a dotted line, the latter possibly being able to constitute a hem 40 in which the spacer 7 is threaded.

Selon une caractéristique essentielle de l'invention, la combinaison des éléments de blocage 2 et 3 et de l'en- tretoise 7 est serrée dans un manchon 10 qui, prenant en charge les longerons, obligent ces derniers à se serrer l'un contre-l'autre comme le montre les flèches (F). Ce fourreau 10 joue donc le rôle d'un étau. Il comporte deux flancs 11 et 12 parallèles aux faces externes 13 et 14 des longerons 22 et 33, d'un Tond 15, et d'une partie supérieure 16 ouverte dans e sens longitudinal.Le rond 15 se divise en trois zones : d'une part, deux parties planes servant d'embases 17 et 18 à chacun des deu:- éléments de blocage 20 et 36 d'autre part, une partie en relief 19, en forme de gouttière inversée, reliant ces deux embases 17 et 18. According to an essential characteristic of the invention, the combination of the locking elements 2 and 3 and of the spacer 7 is clamped in a sleeve 10 which, taking care of the beams, force the latter to tighten against each other. -the other as shown by the arrows (F). This sheath 10 therefore plays the role of a vice. It has two sides 11 and 12 parallel to the external faces 13 and 14 of the side members 22 and 33, of a mower 15, and of an upper part 16 open in the longitudinal direction. The round 15 is divided into three zones: on the one hand, two flat parts serving as bases 17 and 18 to each of the two: - blocking elements 20 and 36 on the other hand, a raised part 19, in the form of an inverted gutter, connecting these two bases 17 and 18.

Dans un exemple de réalisation, cette gouttière inversée 19 présente la forme d'un trapèze dont les côtés font un angle (α) avec les embases 17 et 18. Enfin, la partie supérieure comporte, de part et d'autre de l'axe longitudinal, une face inclinée 30 faisant un angle (ss) avec les flancs 1 et 12 et une face plane 31 disposée parallèlement aux embases 17 e 18. In an exemplary embodiment, this inverted gutter 19 has the shape of a trapezoid whose sides make an angle (α) with the bases 17 and 18. Finally, the upper part comprises, on either side of the longitudinal axis, an inclined face 30 forming an angle (ss) with the sides 1 and 12 and a flat face 31 arranged parallel to the bases 17 and 18.

Une fois montés, les films 8 et 9 sont donc insérés dans les machoires que constituent les deux longerons 22 et 33, tandis que l'étau formé par le manchon 10 vient coiffer l'ensemble å intervalles reguliers, structure assurant une pression sur l'ensemble grâce notamment à l'existence des deux angles cassés de la partie supérieure Entre les deux films1 on peut interposer une couche d'isolant 90. Once mounted, the films 8 and 9 are therefore inserted into the jaws that constitute the two side members 22 and 33, while the vice formed by the sleeve 10 covers the assembly at regular intervals, a structure ensuring pressure on the together thanks in particular to the existence of the two broken angles of the upper part Between the two films1 an insulating layer 90 can be interposed.

La longueur (1) du manchon 10, son dimensionnement et les angles (α) et (ss) sont fonction de l'application considérée. The length (1) of the sleeve 10, its dimensioning and the angles (α) and (ss) depend on the application considered.

Dans le montage de l'ensemble, si plusieurs longerons doivent être mis bout à bout, utilisateur s'arrange à positionner un manchon 10 de telle sorte que la jonction de deux longerons bout à bout se trouve positionnée environ au milieu du manchon, soit à une distance voisine de (1/2) des deux faces latérales (x) et (y) externes du manchon. In the assembly of the assembly, if several longitudinal members must be placed end to end, the user arranges to position a sleeve 10 so that the junction of two end-to-end longitudinal members is positioned approximately in the middle of the sleeve, i.e. a distance close to (1/2) of the two lateral (x) and (y) external faces of the sleeve.

Le montage se fait, par exemple, par coulissement du manchon 10 par étapes successives. Si les longerons sont realisés par exemple en ciment et de dimension relativement importantes, leur simple poids suffit à garantir la bonne tenue de l'ensemble. lais on peut également prévoir des systèmes d'ancrage tel qu'une élingue 100 solidaire par exemple de la gouttière 19. The assembly is done, for example, by sliding the sleeve 10 in successive stages. If the side members are made for example of cement and of relatively large size, their simple weight is sufficient to guarantee the good performance of the assembly. but it is also possible to provide anchoring systems such as a sling 100 secured for example to the gutter 19.

Une combinaison de moyens de blocage conforme à l'invention s'adapte tout particulièrement à une structure réalisée par exemple en alliage léger facile à manipuler sous réserve de disposer, comme cela a été dit précédemment, de moyens d'ancrage. A combination of locking means according to the invention is particularly suitable for a structure made for example of light alloy easy to handle provided that, as has been said previously, anchoring means.

Cette disposition des longerons formant mâchoire permet éventuellement la mise en place d'un matériau isolant 90 entre les deux films 8 et 9. La couverture ainsi constituée repose de manière classique sur une ossature par exemple en arceau, que cette ossature soit directement posée sur le sol ou au contraire sur un mur ou tout autre support. This arrangement of the longitudinal members forming the jaw optionally allows the installation of an insulating material 90 between the two films 8 and 9. The cover thus formed conventionally rests on a frame, for example in an arch, that this frame is placed directly on the floor or on the contrary on a wall or any other support.

Une des principales applications de l'invention se rencontrent dans la fabrication de serres, des couvertures de terrain de sport, de bâtiments agricoles et industriels.  One of the main applications of the invention is found in the manufacture of greenhouses, covers for sports grounds, agricultural and industrial buildings.
