DISPOSITIF D' AUTO-ULAT ION DES TENSIONS POUR CHASSIS BEAUX-ARTS
La présente invention concerne les chassis pour les oeuvres d'art peintes sur toile. La bonne conservation de ces peintures dépend entre autre du type de chassis sur lequel elle est tendue.VOLTAGE SELF-ULTRA ION DEVICE FOR FINE ARTS CHASSIS
The present invention relates to frames for works of art painted on canvas. The good conservation of these paintings depends on the type of frame on which it is stretched.
La tension des peintures d'art sur toile se fait traditionnellement sur des chassis en bois, fixes ou munis d'un dispositif d'écartement des montants par 11 intermédiaire de clefs. Dans ce cas la conservation des oeuvres est tributaire des variations climatiques et on voit apparaître sur leur surface la formation d'un réseau de craquelures. The tension of art paintings on canvas is traditionally done on wooden frames, fixed or provided with a device for spacing the amounts through 11 keys. In this case the conservation of the works is dependent on the climatic variations and one sees appear on their surface the formation of a network of cracks.
I1 existe des chassis munis de ressorts aux angles qui permettent d'obtenir une tension continue et de diminuer du point de vue de la conservation le vieillissement de l'oeuvre. Dans ce cas les efforts, transitant aux angles par l'intermédiaire d' équerres en contact avec les ressorts, permettent au chassis de se déformer sous l'action des différentes sollicitations. Ces chassis sont coûteux et leur efficacité est souvent mise en défaut aux angles, dans certaines conditions, de par leur conception. There are chassis equipped with springs at the corners which allow to obtain a continuous tension and to diminish from the point of view of conservation the aging of the work. In this case, the forces, passing through the corners by means of brackets in contact with the springs, allow the chassis to deform under the action of different stresses. These frames are expensive and their effectiveness is often faulted at the corners, under certain conditions, by design.
Le dispositif d'auto-régulation des tensions proposé, reste fiable quelles que soient les conditions, car il est basé sur un principe différent qui fait l'objet de cette demande de brevet. The proposed self-regulation of the voltages remains reliable whatever the conditions, because it is based on a different principle which is the subject of this patent application.
Le principe de ce dispositif d'auto-régulation est obtenu a partir d'une lame en contact avec la peinture sur toile, qui fléchit ou se raidit sous l'action des sollicitations imposées par la peinture lors des variations hygrométriques. The principle of this self-regulating device is obtained from a blade in contact with the painting on canvas, which flexes or stiffens under the action of the stresses imposed by the paint during hygrometric variations.
L'originalité de ce dispositif se situe au niveau des efforts qui, ne transitant plus par des équerres, sont directement repris par la lame du fait du déplacement de celle-ci qui est en contact avec la peinture. The originality of this device is at the level of efforts that, no longer passing through brackets, are directly taken over by the blade due to the displacement of the latter which is in contact with the paint.
L'efficacité de ce dispositif d'auto-régulation des tensions est étroitement liée à la forme et aux caractéristiques de la lame par rapport aux sollicitations mises en jeux dans une peinture soumise à des variations d'hygrométrie. D'après l'un des principes qui régit l'efficacité d'un dispositif d'auto-régulation, il faut que la raideur de la lame-ressort se situe entre les deux valeurs de la rigidité de la peinture à faible et à forte humidité
Le dispositif d'auto-régulation des tensions pour chassis fig 1, est composé essentiellement d'une lame A, dont les dimensions ont été calculées à partir des sollicitations provoquées par une peinture traditionnelle soumise à des variations hygrométriques, de manière à assurer au dispositif le maximum d'efficacité. Cette lame A s'encastre selon le cas; - Fig 2a dans un chassis à dimensions réglables C le plus près des bords extérieurs.The effectiveness of this self-regulating tension device is closely related to the shape and characteristics of the blade with respect to the stresses involved in a painting subjected to hygrometry variations. According to one of the principles governing the efficiency of a self-regulating device, it is necessary that the stiffness of the spring blade is between the two values of the stiffness of the paint at low and high humidity
The device for self-regulation of the voltages for chassis fig 1, is essentially composed of a blade A, whose dimensions have been calculated from the stresses caused by a traditional painting subjected to hygrometric variations, so as to ensure the device the maximum efficiency. This blade A is fitted as appropriate; - Fig 2a in a frame with adjustable dimensions C closest to the outer edges.

B which will be fixed later on a chassis C, if one wants that the device remains independent and applicable to any chassis.
Comme la lame A doit répondre en flexion à des sollicitations précises, la largeur active 1 et l'épaisseur e seront calculées en fonction du matériau utilisé, de manière à respecter le déplacement maximum que peut subir une peinture sans s'altérer fig 4
Afin d'éviter que les lames en flexion se butent aux angles, elles doivent être coupées avec un certain angle par rapport à la base fig. 6.As the blade A must respond in bending with precise stresses, the active width 1 and the thickness e will be calculated according to the material used, so as to respect the maximum displacement that can undergo a painting without deteriorating fig 4
In order to prevent the bending blades from bending at the corners, they must be cut at an angle to the base fig. 6.
Le dispositif, objet de l'invention, est conçu de telle manière que les tensions dans un tableau peint sur toile ne dépassent jamais le seuil de rupture de la peinture sèche, lorsque l'humidité relative varie d'environ 35% à 75% pour une température 200C à 240C. Ce dispositif peut-être utilisé par les artistes peintres et les restaurateurs de tableaux. The device, object of the invention, is designed in such a way that the tensions in a painting on canvas never exceed the breaking threshold of the dry paint, when the relative humidity varies from about 35% to 75% for a temperature 200C to 240C. This device can be used by painters and restorers of paintings.
