Abstract

The tension device comprises a spring 10 which is precoiled under tension on one 8 of two reels, the other reel 9 receiving in the opposite direction the free end of the said spring, so as to impart to the drum 11, intended for the coiling of the tension cable 5 associated with the loading bar of the awning, a practically constant strong torque.

Description

La présente invention a trait aux dispositifs de store dont la toile ou autre couverture souple est destinée à être déployée substantiellement à l'horizontale et dans lesquels les manoeuvres d'envidage et de dévidage nécessitent la présence de câbles fixés à la barre de charge et associes à des tendeurs élastiques. The present invention relates to awning devices whose fabric or other flexible cover is intended to be deployed substantially horizontally and in which the operations of unwinding and unwinding require the presence of cables attached to the load bar and associated to elastic tensioners.

l'objet de l'invention est constitue par un tendeur élastique pour store, caractérisé en ce qu'il comprend deux bobines sur lesquelles s'enroulent en sens opposes les deux extrémités libres d'un ressort à lame pré-tendu sur l'une desdites bobines, celle de ces bobines qui est rendue solidaire de l'extremite du ressort enroulée à contre-sens étant liée angulairement au tambour destine à recevoir le câble correspondant attaché à la barre de charge. the object of the invention is constituted by an elastic tensioner for blind, characterized in that it comprises two coils on which are wound in opposite directions the two free ends of a pre-tensioned leaf spring on one of said coils, that of these coils which is made integral with the end of the spring wound in the opposite direction being angularly linked to the drum intended to receive the corresponding cable attached to the load bar.

Les essais ont démontré qu'un tel système permettait l'obtention, sur le tambour récepteur de câble, d'un couple résistant pratiquement constant tout au long de la course de la toile du store. Tests have shown that such a system made it possible to obtain, on the cable receiving drum, a practically constant resistive torque throughout the travel of the awning fabric.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en perspective montrant l'agencement général d'un dispositif de store à déploiement horizontal, équipé de deux tendeurs élastiques suivant l'invention.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a perspective view showing the general arrangement of a blind device with horizontal deployment, equipped with two elastic tensioners according to the invention.

Fig. 2 est une vue en plan schématique de l'un de ces tendeurs. Fig. 2 is a schematic plan view of one of these tensioners.

Fig. 3 en est une coupe longitudinale suivant III-III (fig. 2). Fig. 3 is a longitudinal section along III-III (fig. 2).

Le dispositif de store illustré en fig. 1 comprend à la façon en soi connue un arbre horizontal 1 porté par des flasques d'extrémités 2 rendus solidaires d'une façade de construction. Cet arbre 1 forme tambour d'enroulement pour la toile 3 dont l'extrémité libre est munie d'une barre de charge 4 sur laquelle s'attache l'une des extrémités de deux câbles longitudinaux 5 orients à l'horizontale, perpendiculairement à l'arbre 1. L'extrémité opposée de chaque câble 5 coopère avec un tendeur élastique A fixé à une autre façade de construction de façon à ce que la toile 3 puisse s'étendre lorsque désiré au-dessus de l'espace libre qui sépare les deux façades envisagées, la commande de l'arbre 1 étant effectuée à l'aide d'un mécanisme manuel ou d'un moteur (non représenté). The blind device illustrated in fig. 1 comprises in the manner known per se a horizontal shaft 1 carried by end flanges 2 made integral with a building facade. This shaft 1 forms a winding drum for the fabric 3, the free end of which is provided with a load bar 4 to which one of the ends of two longitudinal cables 5 attached horizontally is attached, perpendicular to the 'shaft 1. The opposite end of each cable 5 cooperates with an elastic tensioner A fixed to another construction facade so that the fabric 3 can extend when desired above the free space which separates the two facades envisaged, the control of the shaft 1 being carried out using a manual mechanism or a motor (not shown).

Comme montre en fig. 2 et 3, chaque tendeur A comprend, dans l'exemple de réalisation pris en considération, un support 6 à profil en équerre dont la branche horizontale est solidaire de deux axes verticaux 7 sur chacun desquels est montée folle une bobine 8, respectivement 9 ; ces deux bobines sont réunies par un ressort à lame 10 dont les extrémités sont profilées pour s'ancrer dans le moyeu desdites bobines, étant observé que le sens d'enroulement dudit ressort 10 sur les bobines est inversé. On notera également que la bobine 9 comporte un prolongement supérieur conformé de manière à constituer tambour d'enroulement pour l'extrémité libre du câble 5 correspondant (une seule spire d'enroulement a été représentée en fig. 2 afin de mieux illustrer l'agencement). As shown in fig. 2 and 3, each tensioner A comprises, in the embodiment taken into consideration, a support 6 with an angled profile, the horizontal branch of which is integral with two vertical axes 7 on each of which a spool 8, 9 respectively is mounted; these two coils are joined by a leaf spring 10 whose ends are profiled to anchor in the hub of said coils, it being observed that the direction of winding of said spring 10 on the coils is reversed. It will also be noted that the coil 9 has an upper extension shaped so as to constitute a winding drum for the free end of the corresponding cable 5 (a single winding turn has been shown in FIG. 2 in order to better illustrate the arrangement ).

On conçoit que si l'enroulement réalisé sur la bobine 8 correspond
au sens pour lequel ledit ressort a été formé à l'origine et si ledit ressort a Eté pre-tendu sur ladite bobine, il exerce sur la bobine 9 un couple qui tend à faire tourner cette dernière en sens inverse, et ce par suite de l'inversion du sens d'enroulement du ressort sur cette bobine 9.On obtient de la sorte sur la bobine 9 et sur le tambour 11 qu'elle porte, un effort résistant pratiquement constant qui assure la tension permanente du câble 5 envisagé à toutes les positions longitudinales de la toile 2 du store. L'envidage et le dévidage de cette toile 2 sur l'arbre 1 lorsque celui-ci est manoeuvre angulairement s'effectuent de façon parfaitement régulière, les deux tendeurs A opérant en outre la récupération efficace de tout effet de mou déterminé par les sautes de vent sur la toile précitée.
It is understood that if the winding produced on the coil 8 corresponds
in the sense for which said spring was originally formed and if said spring has been pre-tensioned on said coil, it exerts on coil 9 a torque which tends to rotate the latter in the opposite direction, and this as a result of the reversal of the direction of winding of the spring on this coil 9. In this way, one obtains on the coil 9 and on the drum 11 which it carries, a practically constant resistant force which ensures the permanent tension of the cable 5 envisaged for all the longitudinal positions of the fabric 2 of the blind. The unloading and reeling of this fabric 2 on the shaft 1 when the latter is angularly maneuvered is carried out in a perfectly regular manner, the two tensioners A also operating the effective recovery of any slack effect determined by the swings of wind on the aforementioned canvas.

Il va de soi que le nombre des tendeurs A varie en fonction de la largeur de la toile 2. On comprend de plus qu'en certains cas le câble 5 peut s'enrouler sur-un tambour indépendant de la bobine 9 à laquelle il peut être relie angulairement par tout mécanisme de transmission approprie. It goes without saying that the number of tensioners A varies according to the width of the fabric 2. It is further understood that in some cases the cable 5 can be wound on a drum independent of the coil 9 to which it can be connected angularly by any suitable transmission mechanism.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'a titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should also be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
