Description

Domaine techniqueTechnical area

La présente invention concerne un châssis toilé pour artiste peintre présentant un aspect fini stable dans le temps et permettant d'obtenir facilement et de maintenir un tendu requis de ladite toile à peindre.The present invention relates to a canvas frame for a painter with a stable finish over time and to easily obtain and maintain a required tension of said painting canvas.

Technique antérieurePrior art

On sait que, pour fabriquer un châssis toilé destiné à être peint, on utilise classiquement une toile en coton ou en lin et un châssis formé d'au moins quatre montants encollés, réalisés en bois avantageusement de type conifère, tel que par exemple de l'épicéa, et dont la section transversale est de préférence trapézoïdale afin que la toile une fois tendue, ne soit en contact qu'avec l'arête externe desdits montants afin de ne pas laisser apparaître des marques inesthétiques dues auxdits montants.It is known that, in order to manufacture a canvas frame intended to be painted, a cotton or linen fabric is conventionally used and a frame made up of at least four glued posts made of wood, advantageously of the coniferous type, such as for example spruce, and whose cross section is preferably trapezoidal so that the fabric once tensioned, is in contact only with the outer edge of said uprights so as not to leave unsightly marks due to said amounts.

Une fois le châssis réalisé, la toile est découpée en laissant une surlongueur afin de la mettre en place en la repliant sur l'arrière dudit châssis en la tendant. Une fois, appliquée et tendue sur ledit châssis, la toile est agrafée avec des agrafes ou des pointes dites "semences de tapissier". Toutefois, une tension parfaite de la toile sur le châssis est difficile à obtenir compte tenu de la technique d'agrafage. Pour améliorer la tension, la toile peut être mise en place légèrement humide sur le châssis; en séchant, la toile se tendra alors fortement sur ledit châssis. Par ailleurs, lorsque la toile est détendue sous l'effet des années, ladite toile pourra, le cas échant, être retendue par des clés. Lesdites clés sont de petites pièces de bois de forme globalement triangulaire dont l'angle le plus aigu peut être glissé dans de petits orifices prévus à cet effet disposés par paires à chaque angle intérieur du châssis.Once the frame is made, the fabric is cut leaving an excess length to put it in place by folding on the rear of said frame by extending it. Once applied and stretched on said frame, the fabric is stapled with staples or points called "upholsterer seeds". However, a perfect tension of the fabric on the frame is difficult to obtain given the stapling technique. To improve the tension, the fabric can be placed slightly damp on the chassis; as it dries, the canvas will then strongly tighten on said frame. Moreover, when the fabric is relaxed under the effect of years, said canvas may, if necessary, be retold by keys. Said keys are small pieces of generally triangular shaped wood whose highest angle can be slid into small holes provided for this purpose arranged in pairs at each inside corner of the frame.

Une fois la toile mise en place, celle-ci doit encore être préparée afin d'être apte à être peinte. La préparation consiste en une enduction de la toile d'une ou plusieurs couches de produits tels que de la colle de peau ou des enduits vinyliques. Toutefois, pour parfaire l'aspect lisse de la toile, il est nécessaire de poncer légèrement la surface de la toile, entre chaque couche de produits d'enduction. De même, à la fin de l'enduction, un dernier ponçage et une dernière tension de la toile, par exemple à l'aide des clés, seront indispensables.Once the canvas is put in place, it must still be prepared in order to be able to be painted. The preparation consists of coating the fabric with one or more layers of products such as skin glue or vinyl coatings. However, to perfect the smooth appearance of the fabric, it is necessary to lightly sand the surface of the fabric, between each layer of coating products. Similarly, at the end of the coating, a final sanding and a last tension of the fabric, for example using the keys, will be essential.

Avec une telle configuration, on comprend bien que la réalisation d'un châssis toilé selon l'Art antérieur est fastidieuse et nécessite de nombreuses opérations délicates pour fabriquer ledit châssis, tendre, agrafer et préparer la toile. Par ailleurs, ledit châssis toile ainsi obtenu ne présente pas un aspect très esthétique dû essentiellement au mode de tension et de fixation de la toile sur ledit châssis et il est donc souvent nécessaire d'ajouter un cadre autour du châssis toilé pour parfaire son aspect fini. En outre, avec ce mode de fabrication, il est difficile de fabriquer un châssis toilé ayant une forme autre que carrée, losange ou rectangulaire.With such a configuration, it is clear that the realization of a canvas frame according to the prior art is tedious and requires many delicate operations to manufacture said frame, stretch, staple and prepare the fabric. Furthermore, said canvas frame thus obtained does not have a very aesthetic appearance due essentially to the mode of tension and fixing the fabric on said frame and it is therefore often necessary to add a frame around the canvas frame to complete its finished appearance . In addition, with this method of manufacture, it is difficult to manufacture a canvas frame having a shape other than square, rhombus or rectangular.

De même, la toile utilisée, qui est classiquement réalisée en lin ou en coton, est très sensible aux variations de chaleur et à l'humidité; elle se détend donc très souvent et nécessite alors d'être retendue à l'aide notamment des clés disposées à l'arrière du châssis. Par ailleurs, lorsque la toile reçoit un impact, une empreinte en forme de creux ou de bosse apparaît et cette marque est très difficile à faire disparaître compte tenu de la rigidité de la matière de ladite toile. Par ailleurs, avec ce genre de toiles, il n'est pas possible d'avoir plusieurs textures sur le même châssis afin de créer des effets artistiques.Similarly, the canvas used, which is conventionally made of linen or cotton, is very sensitive to variations in heat and humidity; it therefore relaxes very often and then needs to be re-stretched with the help of keys located at the rear of the chassis. Moreover, when the fabric receives an impact, a cavity-like or bump-shaped imprint appears and this mark is very difficult to remove due to the rigidity of the material of said fabric. Moreover, with this kind of paintings, it is not possible to have several textures on the same frame to create artistic effects.

Un autre exemple de la technique antérieure est présenté dans la publication FR2916158 .Another example of the prior art is presented in the publication FR2916158 .

Meilleure manière de réaliser l'invention techniqueBest way to realize the technical invention

Dans la description ci-après, on ne va décrire qu'un châssis toilé pour artiste peintre selon l'invention de forme rectangulaire destiné à être accroché sur une paroi verticale, mais il va de soi que ledit châssis toilé pourra avoir une toute autre forme telle que carré, triangulaire, ronde, elliptique ou encore gauche par exemple, sans sortir du cadre de la présente invention.In the following description, only a canvas frame for a painter according to the invention of rectangular shape intended to be hung on a vertical wall will be described, but it goes without saying that said canvas frame may have a completely different shape. such as square, triangular, round, elliptical or left for example, without departing from the scope of the present invention.

De même, si le châssis toilé selon l'invention est accroché sur une paroi non verticale, les termes vertical et/ou horizontal seront alors à adapter à l'inclinaison de ladite paroi.Similarly, if the canvas frame according to the invention is hung on a non-vertical wall, the terms vertical and / or horizontal will then be adapted to the inclination of said wall.

En référence aux figures 1 à 3, le châssis toilé 1 comprend un cadre 2 fermé rectangulaire comprenant quatre lisses 3 et une toile à peindre tendue sur ledit cadre 12, la toile à peindre étant constituée d'une nappe souple 4 comprenant une toile 41 avantageusement extensible et un moyen d'accrochage 42 fixé à la périphérie de ladite toile 41 et permettant la fixation de ladite nappe souple 4 sur ledit cadre 2.With reference to Figures 1 to 3 , the canvas frame 1 comprises a rectangular closed frame 2 comprising four rails 3 and a canvas to be stretched on said frame 12, the canvas to be painted consisting of a flexible sheet 4 comprising a canvas 41 advantageously extensible and a hooking means 42 fixed to the periphery of said fabric 41 and allowing the attachment of said flexible sheet 4 to said frame 2.

On comprend bien que dans le cas d'un cadre 2 de forme rond ou elliptique par exemple, le dit cadre 2 pourra ne comporter qu'une seule lisse 3 recourbée sur elle-même.It is well understood that in the case of a frame 2 of round or elliptical shape for example, said frame 2 may have only one smooth 3 curved on itself.

La lisse 3 peut, par exemple, prendre la forme de celle représentée sur les figures 1 à 3 et plus particulièrement sur la figure 3. Ainsi, la lisse 3 est de section globalement carrée et comprend au moins une aile externe 31, qui s'étend de préférence sensiblement perpendiculairement à ladite nappe souple 4, lorsqu'elle est tendue sur ledit cadre 2. De cette aile externe 31 est issue, à peu près à mi-hauteur, une âme intérieure 32 s'étendant sur une faible distance en direction de l'intérieur dudit cadre 2 du châssis toilé 1. Cette âme intérieure 32 rejoint, à son extrémité libre, une aile interne 33 s'étendant vers l'extérieur dudit cadre 2, parallèlement à l'aile externe 31. La lisse 3 comporte également un appui périphérique 35 étroit formé par l'extrémité libre de l'aile interne 33 qui se prolonge de sorte à dépasser la face externe 34 verticale de la lisse 3 qui se trouve du coté de la nappe souple 4. En outre, l'aile externe 31 présente un épaulement 36 s'étendant perpendiculairement de son extrémité libre en direction de l'aile verticale interne 33.The beam 3 may, for example, take the form of that represented on the Figures 1 to 3 and more particularly on the figure 3 . Thus, the arm 3 is of generally square section and comprises at least one outer wing 31, which preferably extends substantially perpendicularly to said flexible sheet 4, when stretched on said frame 2. From this outer wing 31 is issued , about halfway up, an inner soul 32 extending a short distance in the direction of the interior of said frame 2 of the canvas frame 1. This inner core 32 joins, at its free end, an inner flange 33 extending outwardly of said frame 2, parallel to the outer flange 31. The stringer 3 also comprises a narrow peripheral support 35 formed by the free end of the inner wing 33 which extends so as to exceed the vertical outer face 34 of the rail 3 which is on the side of the flexible web 4. In addition, the wing outer 31 has a shoulder 36 extending perpendicularly from its free end towards the vertical vertical wing 33.

La partie libre de l'aile externe 31, l'âme intérieure 32, l'aile interne 33 et l'épaulement 36 déterminent un évidement 37 ouvert, du coté opposé à ladite âme intérieure 32.The free portion of the outer flange 31, the inner core 32, the inner flange 33 and the shoulder 36 define a recess 37 open on the side opposite to said inner core 32.

La lisse 3 comporte en outre un logement interne 38 apte à coopérer avec au moins un organe de liaison 5, avantageusement de type équerre, pour assembler entre elles des lisses 3 adjacentes et former ledit cadre 2.The arm 3 further comprises an inner housing 38 adapted to cooperate with at least one connecting member 5, advantageously of angle-type, for assembling together adjacent rails 3 and forming said frame 2.

Enfin, afin de ne pas détériorer la nappe souple 4 et son moyen d'accrochage 42 périphérique, l'aile verticale interne 33 et l'épaulement 36 présentent avantageusement une extrémité libre arrondie.Finally, in order not to damage the flexible ply 4 and its peripheral fastening means 42, the inner vertical flange 33 and the shoulder 36 advantageously have a rounded free end.

De même, pour faciliter la mise en place de la nappe souple 4, l'épaulement pourra comporter un pan coupé (non représenté) afin de faciliter l'insertion du moyen d'accrochage 42 de ladite nappe souple 4 dans l'évidement 37 de la lisse 3.Similarly, to facilitate the introduction of the flexible sheet 4, the shoulder may include a cutaway (not shown) to facilitate the insertion of the attachment means 42 of said flexible sheet 4 in the recess 37 of the smooth 3.

Pour faciliter la manipulation du châssis toilé 1 selon l'invention tout en garantissant sa tenue dans le temps, la lisse 3 est de préférence réalisée à partir de profilés extrudés de section carrée, rectangulaire ou encore ronde réalisés en alliage léger tel que par exemple un alliage d'aluminium.To facilitate the handling of the canvas frame 1 according to the invention while ensuring its resistance over time, the arm 3 is preferably made from extruded profiles of square, rectangular or round section made of light alloy such as for example a aluminum alloy.

La nappe souple 4 comporte donc un moyen d'accrochage 42 périphérique avantageusement un harpon présentant une forme de crochet apte à coopérer avec la lisse 3 en s'engageant dans son évidement 37. Ainsi, ledit moyen d'accrochage 42 comprend une branche interne 421 par laquelle il est fixé à la toile 41 de la nappe souple 4 et une branche externe 422 en forme de bourrelet à l'extrémité arrondie recourbée en direction de ladite toile 41. Lesdites branches interne et externe 421, 422 sont avantageusement issues de matière.The flexible sheet 4 thus comprises a gripping means 42 advantageously a harpoon having a hook shape adapted to cooperate with the bar 3 by engaging in its recess 37. Thus, said hooking means 42 comprises an inner branch 421 by which it is fixed to the web 41 of the flexible web 4 and an outer branch 422 in the form of a bead at the rounded end curved towards said fabric 41. Said inner and outer legs 421, 422 are advantageously made of material.

Une fois inséré dans l'évidement 36 de la lisse 3, ledit moyen d'accrochage 42 prend alors appui sur l'épaulement 36 avec l'extrémité libre de sa branche externe 422 et permet de maintenir tendue la nappe souple 4 extensible uniquement en appui sur l'appui périphérique 35 formé par l'extrémité libre de l'aile interne 33 de la lisse 3.Once inserted in the recess 36 of the rail 3, said hooking means 42 then bears on the shoulder 36 with the free end of its outer arm 422 and makes it possible to keep the supple flexible sheet 4 stretched only in support on the peripheral support 35 formed by the free end of the inner wing 33 of the rail 3.

Ainsi, compte tenu de la faible épaisseur de l'aile interne 33, le châssis toilé 1 ne présente aucune marque inesthétique en périphérie.Thus, given the small thickness of the inner flange 33, the canvas frame 1 has no unsightly mark on the periphery.

On comprend que bien que l'évidement 37 ouvert et les éléments qui le déterminent à savoir l'aile externe 31, l'âme intérieure 32, l'aile interne 33 et l'épaulement 36 pourront être disposés différemment, par exemple pivotés de 90° vers l'extérieur du cadre 2, sans sortir du cadre de la présente invention.It is understood that although the recess 37 open and the elements that determine it namely the outer flange 31, the inner core 32, the inner flange 33 and the shoulder 36 may be arranged differently, for example rotated 90 ° outwardly of the frame 2, without departing from the scope of the present invention.

Par ailleurs, on comprend bien qu'il n'est plus nécessaire de mettre en place des agrafes ou des clous disgracieux. Ainsi, le châssis toilé présente bien un aspect fini et peut être exposé sans cadre supplémentaire.Furthermore, it is clear that it is no longer necessary to put in place staples or unsightly nails. Thus, the canvas frame has a finite appearance and can be exposed without additional frame.

Pour obtenir une tension homogène et remarquable, notamment dans le temps, on comprend bien que la toile 41 de la nappe souple 4 doit être extensible et que la nappe souple 4 ne doit pas avoir de dimensions trop importantes. Ainsi, la toile 41 de la nappe souple 4 sera réalisée à partir d'au moins une feuille en matière plastique extensible, avantageusement en polychlorure de vinyle (PVC), et aura une forme globalement homothétique à celle du cadre 2 du châssis toilé 1 et des dimensions réduites, le taux de réduction employé étant pour une toile 41 en PVC de 7%.To obtain a homogeneous and remarkable tension, especially over time, it is clear that the web 41 of the flexible web 4 must be extensible and that the flexible web 4 must not have too large dimensions. Thus, the fabric 41 of the flexible ply 4 will be made from at least one extensible plastic sheet, advantageously made of polyvinyl chloride (PVC), and will have a shape generally homothetic to that of the frame 2 of the fabric frame 1 and reduced dimensions, the reduction rate used for a fabric 41 PVC 7%.

Cette configuration de nappe souple 4 extensible permet, d'une part, d'assurer dans le temps une tension remarquable et, d'autre part, d'éviter que des empreintes générées par un petit impact ne restent apparentes. En effet, on comprend bien que si l'on appuie sur une nappe souple 4 extensible tendue et que l'on relâche la pression, ladite nappe souple 4 reprend sa forme plane initiale ne laissant apparaitre aucune empreinte.This expandable flexible web configuration 4 makes it possible, on the one hand, to ensure a remarkable tension over time and, on the other hand, to prevent footprints generated by a small impact from remaining apparent. Indeed, it is understood that if one presses a stretched flexible ply 4 stretched and releasing the pressure, said flexible ply 4 resumes its original planar shape leaving no imprint.

De même, on comprend bien qu'une nappe souple 4 en matière plastique en général et en PVC en particulier, n'est pas sensible à l'humidité, ni aux variations de température dans un local fermé et est donc particulièrement stable dans le temps.Similarly, it is well understood that a flexible sheet 4 of plastic in general and PVC in particular, is not sensitive to moisture or temperature variations in a closed room and is therefore particularly stable over time .

En outre, une nappe souple 4 réalisée en PVC est non seulement facile à mettre en oeuvre car il suffit d' insérer son moyen d'accrochage 42 dans l'évidement 36 de la lisse 3 du cadre 2 pour la fixer tendue, mais également facile à utiliser car elle ne nécessite aucune préparation préalable à l'application de la peinture. Il convient juste d'utiliser un type peinture compatible et notamment prévue pour accrocher sur la toile 41 extensible de la nappe souple 4 réalisée à partir d'au moins une feuille en matière plastique avantageusement de type PVC.In addition, a flexible sheet 4 made of PVC is not only easy to implement because it is sufficient to insert its attachment means 42 in the recess 36 of the smooth 3 of the frame 2 to fix it taut, but also easy to use because it does not require any preparation prior to the application of the paint. It is just appropriate to use a compatible paint type and in particular designed to hang on the extensible web 41 of the flexible web 4 made from at least one plastic sheet preferably PVC type.

De plus, une nappe souple 4 en PVC est également très intéressante car elle peut avoir différentes présentations, elle peut être opaque, transparente, translucide, mate ou brillante, pleine ou perforée, satinée ou encore de différentes couleurs. Elle peut également être revêtue au moins en partie de textures donnant un effet de matière spécifique telle que par exemple du velours, du bois ou encore du métal.In addition, a flexible sheet 4 PVC is also very interesting because it can have different presentations, it can be opaque, transparent, translucent, matte or glossy, full or perforated, satin or even different colours. It may also be coated at least in part with textures giving an effect of specific material such as for example velvet, wood or metal.

De plus, on sait que le PVC se soude ou se colle parfaitement, on pourra donc réaliser une nappe souple 4 en partant d'une toile 41 formée à partir d'un patchwork de différents types de PVC afin de créer un effet artistique.In addition, it is known that the PVC is welded or sticks perfectly, so we can make a flexible sheet 4 starting from a canvas 41 formed from a patchwork of different types of PVC to create an artistic effect.

Enfin, en utilisant un PVC translucide ou transparent et en disposant au moins une source lumineuse derrière le coté visible du châssis toilé 1, on comprend bien que l'on peut rétro-éclairé ledit châssis toilé 1 et ainsi obtenir des effets de lumière pour mettre en relief au moins une partie de la nappes souple 4.Finally, using a translucent or transparent PVC and having at least one light source behind the visible side of the canvas frame 1, it is understood that we can back-light said canvas frame 1 and thus obtain light effects to put in relief at least a portion of the flexible ply 4.

Description d'autres modes de réalisationDescription of other embodiments

La lisse 2 décrite ci-dessus n'est qu'une variante d'exécution préférentielle et l'Homme du Métier pourra concevoir une lisse 2 de forme différente procurant les mêmes effets sans sortir du cadre de la présente invention.The arm 2 described above is only a variant of preferred embodiment and the skilled person can design a smooth 2 of different shape providing the same effects without departing from the scope of the present invention.

Ainsi, selon une variante de réalisation représentée sur les figures 4 et 5, le cadre 12 du châssis toilé 1 est constitué de lisses 13 et une nappe souple 4 identique à celle décrite précédemment. Ladite nappe souple 4 comprend donc une toile 41 avantageusement extensible et un moyen d'accrochage 42 fixé à la périphérie de ladite toile 41 et permettant la fixation de ladite nappe souple 4 sur ledit cadre 12.Thus, according to an alternative embodiment shown on the Figures 4 and 5 , the frame 12 of the canvas frame 1 consists of smooth 13 and a flexible sheet 4 identical to that described above. Said flexible sheet 4 thus comprises a fabric 41 that is advantageously extensible and a fastening means 42 fastened to the periphery of said fabric 41 and allowing the attachment of said flexible sheet 4 to said frame 12.

Dans cette variante de réalisation, la lisse 13 a une section en forme générale de triangle rectangle et comprend au moins une aile externe 131, qui s'étend de préférence sensiblement perpendiculairement à ladite nappe souple 4, lorsqu'elle est tendue sur ledit cadre 12. De cette aile externe 131 est issue une âme intérieure 132 s'étendant sur une faible distance en direction de l'intérieur dudit cadre 12 du châssis toilé 1. Cette âme intérieure 132 rejoint, à son extrémité libre, une aile interne 133 s'étendant vers l'extérieur dudit cadre 12, parallèlement à l'aile externe 131. L'aile interne 33 se prolonge de sorte à rejoindre la face inclinée 134 de la lisse 13 qui se trouve du coté intérieur du cadre 12 afin de former l'appui périphérique 135 étroit de ladite lisse 13. En outre, l'aile externe 131 présente un épaulement 136 s'étendant perpendiculairement en direction de l'aile verticale interne 133.In this variant embodiment, the arm 13 has a generally triangular-shaped cross-section and comprises at least one outer wing 131, which preferably extends substantially perpendicular to said flexible sheet 4, when it is stretched on said frame 12 From this outer wing 131 is derived an inner core 132 extending over a small distance towards the interior of said frame 12 of the canvas frame 1. This inner core 132 joins, at its free end, an inner flange 133 extending outwardly of said frame 12, parallel to the outer flange 131 The inner wing 33 is extended so as to join the inclined face 134 of the rail 13 which is on the inner side of the frame 12 to form the narrow peripheral support 135 of said rail 13. In addition, the outer wing 131 has a shoulder 136 extending perpendicularly towards the vertical vertical wing 133.

La partie libre de l'aile externe 131, l'âme horizontale intérieure 132, l'aile interne 133 et l'épaulement 136 déterminent un évidement 137 ouvert du coté opposé à ladite âme intérieure 132 et apte à coopérer avec le moyen d'accrochage 42 de la nappe souple 4 pour permettant sa fixation sur ledit cadre 12.The free portion of the outer flange 131, the inner horizontal core 132, the inner flange 133 and the shoulder 136 define a recess 137 open on the opposite side to said inner core 132 and adapted to cooperate with the fastening means 42 of the flexible sheet 4 for fixing it to said frame 12.

En outre, la lisse 13 comporte également un logement interne 138 apte à coopérer avec au moins un organe de liaison (non représentés), avantageusement de type équerre, pour assembler entre elles des lisses 13 adjacentes et former ledit cadre 12.In addition, the arm 13 also comprises an internal housing 138 adapted to cooperate with at least one connecting member (not shown), advantageously of square type, for assembling together adjacent rails 13 and forming said frame 12.

Enfin, cette variante de réalisation de châssis toilé 1 comporte un cadre 12 de plus grande épaisseur et permet donc de mettre en place plus facilement des sources lumineuses derrière la nappe souple 4.Finally, this embodiment of canvas frame 1 comprises a frame 12 of greater thickness and therefore makes it easier to set up light sources behind the flexible sheet 4.

Possibilité d'application industriellePossibility of industrial application

On comprend bien que le châssis toilé 1 selon l'invention peut avantageusement être utilisé pour tout type de peintures et toutes techniques de peintures. En effet, avec une nappe souple 4 présentant un état de surface très lisse, ce châssis toilé 1 permet la réalisation notamment de grattage, d'estompe, d'empâtement et de lissage de la peinture. Par ailleurs, la toile 41 de la nappe souple 4 est également imprimable par tous types de procédés tels que, par exemple, la sérigraphie.It is well understood that the canvas frame 1 according to the invention can advantageously be used for all types of paints and all painting techniques. Indeed, with a flexible sheet 4 having a very smooth surface state, this canvas frame 1 allows the realization including scraping, fading, impasto and smoothing the paint. Furthermore, the web 41 of the flexible web 4 is also printable by all types of processes such as, for example, screen printing.

Enfin, il va de soi que l'exemple de châssis toilé 1 conforme à l'invention qui vient d'être décrit n'est qu'une illustration particulière, en aucun cas limitative de l'invention.Finally, it goes without saying that the example of canvas frame 1 according to the invention which has just been described is only a particular illustration, in no way limiting the invention.
