Abstract

The invention consists in progressively tensioning a flexible element 3, of the blind-canvas (-cloth) type, for a large area. The flexible element 3 is unwound or wound up on a tube 4. The load bar 5 connects the flexible element 3 to the pulling strap 6. The latter is connected at the other end to a roller 7 and wound up in the opposite direction to the winding-up of the flexible element 3. The differences in diameter of the flexible element 3 and of the roller 7 for unwinding or winding-up are compensated for by the elastic pulling system 8. The device has the effect of progressively tensioning the flexible element 3 as it is unwound. The presentation of the assembly is contained in an aluminium profiled section 9 of small cross-section which also serves for guiding the load bar 5.

Description

DISPOSITIF DE TENSION PROGRESSIVE
D'UN ELEMENT SOUPLE ENROULABLE
La présente invention consiste b dérouler un élément souple de très grande surface pour protection thermique et solaire (genre véranda).PROGRESSIVE TENSION DEVICE
OF A FLEXIBLE ROLLABLE ELEMENT
The present invention consists in unwinding a flexible element with a very large surface area for thermal and solar protection (veranda type).

Le dispositif est constitué d'un tube d'enroulement sur lequel l'é- dément souple est enroulé. The device consists of a winding tube on which the flexible element is wound.

Le tube d'enroulement est muni aux extrémités de deux tambours solidaires permettant l'enroulement d'une sangla, celle-ci étant enroulée b l'inverse du sons d'enroulement de l'élément souple, le diamètre de chaque tambour étant égal au diamètre de l'élément souple, enroulé. The winding tube is provided at the ends of two integral drums allowing the winding of a strap, the latter being wound at the opposite of the winding sounds of the flexible element, the diameter of each drum being equal to diameter of the flexible element, wound.

L'élément souple est accroché b une extrémité à la barre de charge, celle-ci étant tirée par la sangle, passant par deux poulies fixes NO I et Ne 2 (voir figure I) et une poulie mobile montée sur glissière, l'autre extrémité de la sangle étant reliée au tambour. The flexible element is hooked at one end to the load bar, the latter being pulled by the strap, passing through two fixed pulleys NO I and Ne 2 (see figure I) and a movable pulley mounted on a slide, the other end of the strap being connected to the drum.

La compensation du tirage entre l'enroulement de l'élément souple et l'enroulement de la sangle est assurée par un dispositif élastique t voir
Figure I (pour un déroulement de l'élément souple de 4 i., le dispositif élastique s'étire de I.20 m. environ)*
On observe dans ce procédé que plus la partie souple se déroule, plus la tension du dispositif élastique s'accentue. The pulling compensation between the winding of the flexible element and the winding of the strap is ensured by an elastic device t see
Figure I (for an unwinding of the flexible element of 4 i., The elastic device stretches by I.20 m. Approximately) *
It is observed in this process that the more the flexible part unwinds, the more the tension of the elastic device increases.

Tout ce dispositif est assemblé dans un profil de faible encombrement et il sert également de coulisse b la barre de charge évitant le flottement par grand vent. All this device is assembled in a compact profile and it also serves as a slide bar for the load bar avoiding floating in strong winds.

Ce dispositif, objet de la présente invention, permet un déroulement total sur la surface b protéger, compte tenu de la poulie fixe N I placés à l'extrémité sans déborder la partie à couvrir. This device, object of the present invention, allows a total unwinding on the surface b to be protected, taking into account the fixed pulley N I placed at the end without overflowing the part to be covered.

Contrairement au brevet N 75 33488, ce dispositif peut être instar lé sur toute surface b protéger, horizontale ou verticale.  Unlike patent N 75 33488, this device can be installed on any surface to be protected, horizontal or vertical.

L'ensemble du dispositif peut etre manoeuvré manuellement par treuil ou par moteur.  The entire device can be operated manually by winch or by motor.
