Description

Domaine techniqueTechnical area

L'invention se rapporte aux dispositifs permettant de réaliser la mise sous tension et le maintien d'une toile ou d'une feuille de papier. De tels dispositifs peuvent par exemple servir de support d'affichage publique ou encore de cadres d'art ou décoratifs.The invention relates to devices for carrying out the tensioning and the maintenance of a canvas or a sheet of paper. Such devices can for example be used as a public display support or even art or decorative frames.

Elle vise plus particulièrement une structure de cadre ou châssis combinée à un agencement d'éléments dans des logements permettant de solidariser de manière réversible par coincement une toile sur un châssis.It relates more particularly to a frame or frame structure combined with an arrangement of elements in housings for reversibly securing by jamming a fabric on a frame.

Art antérieurPrior art

De façon générale, il est connu de solidariser de manière réversible par coincement une toile sur un châssis au moyen de baguettes allongées déformables.In general, it is known to reversibly fasten a web to a frame by means of elongated deformable rods.

Le document FR 2 639 879 décrit ainsi un châssis pour toile présentant une rainure sur sa périphérie. Le dispositif de tensionnement consiste quant à lui, en une baguette allongée comprenant une base plane émergeant de la rainure, et deux ailes parallèles en saillie de ladite base plane et présentant sur leurs faces opposées des bourrelets destinés à venir s'encliqueter dans une embouchure rétrécie de la rainure réalisée dans le châssis.The document FR 2,639,879 thus describes a canvas frame having a groove on its periphery. The tensioning device consists, in turn, of an elongate rod comprising a planar base emerging from the groove, and two parallel wings projecting from said flat base and having on their opposite faces beads intended to snap into a narrowed mouthpiece. of the groove made in the frame.

Ainsi, le dispositif de tensionnement présente des portions sensiblement perpendiculaires qui sont soumises au niveau de leur jonction à des contraintes de cisaillement et ce, lors de l'introduction des deux ailes en saillie à l'intérieur de l'embouchure de la rainure. Si cette déformation est nécessaire pour réaliser le coincement de la toile dans la rainure du châssis, elle fragilise néanmoins la baguette et conduit même à sa destruction après un certain nombre d'utilisations.Thus, the tensioning device has substantially perpendicular portions that are subjected at their junction to shear stresses and this, upon introduction of the two wings projecting inside the mouth of the groove. If this deformation is necessary to achieve the wedging of the fabric in the groove of the frame, it nevertheless weakens the rod and leads to its destruction after a number of uses.

De plus, avec un tel dispositif, le coincement de la toile est réalisé au niveau des extrémités des parois formant l'embouchure rétrécie de la rainure, au moyen de deux arêtes vives en regard l'une de l'autre. Cet agencement génère alors du frottement sur des arêtes vives ce qui endommage par conséquent la toile à chaque opération de mise en place ou d'extraction de la baguette à l'intérieur de la rainure.In addition, with such a device, the jamming of the fabric is made at the ends of the walls forming the narrowed mouth of the groove, by means of two sharp edges facing one another. This arrangement then generates friction on sharp edges, which consequently damages the fabric at each setting operation or extraction of the rod inside the groove.

Le document BE 848 203 décrit également un dispositif permettant de tendre et de maintenir une toile sur un cadre. Dans ce cas, une baguette pénètre à l'intérieur d'une rainure en forme de U. La baguette peut notamment présenter une section transversale en forme de V et coincer la toile grâce à ses deux arêtes longilignes des ailes du V. Ainsi, le coincement de la toile est réalisé entre une surface plane de la rainure et une arête vive de la baguette.The document BE 848 203 also discloses a device for tensioning and holding a canvas on a frame. In this case, a rod penetrates inside a U-shaped groove. The rod may in particular have a V-shaped cross-section and jam the fabric by virtue of its two long ends of the V's wings. jamming of the cloth is made between a flat surface of the groove and a sharp edge of the rod.

Par conséquent, de même que précédemment, ce type d'agencement détériore la toile rapidement et ne permet pas de répéter les opérations de mise en place et de démontage de la toile sur le cadre, sans que celle ci ne s'endommage.Therefore, as before, this type of arrangement deteriorates the canvas quickly and does not allow to repeat the operations of setting up and dismantling the canvas on the frame, without it being damaged.

Exposé de l'inventionPresentation of the invention

L'invention concerne donc un dispositif apte à réaliser la mise sous tension et le maintien d'une toile, comportant un châssis présentant une rainure, et au moins une baguette déformable. La toile est tendue et maintenue sur le châssis par coincement entre la rainure et la baguette déformable.The invention therefore relates to a device adapted to perform the tensioning and the maintenance of a fabric, comprising a frame having a groove, and at least one deformable rod. The canvas is stretched and held on the frame by wedging between the groove and the deformable rod.

Cette baguette déformable présente une section sensiblement en V, orientée vers le fond de la rainure. La baguette déformable comporte une arête vive destinée à servir de pivot pour autoriser sa déformation, et deux flancs aptes à réaliser le coincement de la toile dans la rainure.This deformable rod has a substantially V-shaped section, oriented towards the bottom of the groove. The deformable strip has a sharp edge intended to serve as a pivot to allow its deformation, and two flanks adapted to achieve the jamming of the fabric in the groove.

Autrement dit, les deux flancs de la baguette qui permettent de réaliser le coincement se déplacent en pivotant par rapport à l'arête vive du V orientée vers le fond de la rainure.In other words, the two sides of the rod which make it possible to achieve the jamming move by pivoting with respect to the sharp edge of the V oriented towards the bottom of the groove.

Selon l'invention, le dispositif se caractérise en ce que la baguette vient se bloquer dans un rétrécissement de la rainure au moyen de deux bourrelets s'étendant chacun sur un flanc de la baguette dans la même direction que la baguette.According to the invention, the device is characterized in that the rod is locked in a narrowing of the groove by means of two beads each extending on a side of the rod in the same direction as the rod.

Autrement dit, la baguette est un profilé comportant deux flancs qui présentent chacun un bourrelet sur leur face extérieure.In other words, the rod is a profile having two flanks each having a bead on their outer face.

La baguette comporte un écartement entre les bourrelets au niveau de ses flancs qui est plus large que le rétrécissement de la rainure du châssis. Une pression exercée du coté interne de la baguette, au niveau de l'arête du V permet alors de rapprocher les flancs du V, autorisant la baguette, sous l'effet de la poussée, à descendre dans la rainure du châssis. Les bourrelets pénètrent alors dans le rétrécissement et réalisent un assemblage autobloquant de la toile.The wand has a spacing between the beads at its flanks which is wider than the narrowing of the groove of the frame. A pressure exerted on the inner side of the rod, at the edge of the V then allows to bring the sides of the V, allowing the rod, under the effect of the thrust, to descend into the groove of the frame. The beads then penetrate the narrowing and perform a self-locking assembly of the fabric.

Ainsi, le coincement de la toile est alors réalisé entre deux surfaces tangentielles à l'intérieur de la rainure et à proximité du rétrécissement. Par conséquent, la toile peut être montée et démontée sur le cadre sans que celle ci ne soit endommagée.Thus, the jamming of the fabric is then formed between two tangential surfaces inside the groove and near the narrowing. Therefore, the canvas can be mounted and dismounted on the frame without it being damaged.

En pratique, la baguette peut comporter également deux rabats qui prolongent les flancs et émergent de la rainure pour permettre la préhension et l'extraction de la baguette bloquée à l'intérieur de la rainure.In practice, the strip may also include two flaps that extend the flanks and emerge from the groove to allow gripping and extraction of the blocking rod inside the groove.

Selon les applications, la baguette assurant le coincement peut s'étendre sur la totalité du côté, ou être formée par une pluralité de tronçons indépendants.Depending on the application, the jamming rod may extend over the entire side, or be formed by a plurality of independent sections.

Autrement dit, dans ce dernier cas, dans une direction donnée et sur un même côté du châssis, la toile peut être coincée dans une rainure au moyen de plusieurs éléments distincts formant des tronçons de baguettes indépendants.In other words, in the latter case, in a given direction and on the same side of the frame, the fabric can be wedged in a groove by means of several distinct elements forming sections of independent rods.

Dans certains cas de figures, le châssis peut être démontable en une pluralité de segments. De cette manière, son transport et sa manutention en sont simplifiés.In some cases, the frame can be dismountable into a plurality of segments. In this way, its transport and handling are simplified.

Avantageusement, le châssis peut comporter une pluralité d'agencements permettant de rapporter des barres de renforts pour solidariser deux à deux les segments situés, notamment, sur les côtés opposés du châssis. Ces agencements peuvent se présenter sous la forme de rainures aptes à accueillir des moyens de solidarisation réversibles.Advantageously, the frame may comprise a plurality of arrangements for reporting reinforcing bars to couple in pairs segments located, in particular, on opposite sides of the frame. These arrangements may be in the form of grooves adapted to accommodate reversible fastening means.

Dans un mode de réalisation particulier, le châssis peut comporter des moyens d'accrochage pour le rapporter sur une paroi. Autrement dit, le châssis peut comporter une géométrie particulière destinée à faciliter sa mise en place sur un mur ou plus généralement tout type de cloison.In a particular embodiment, the frame may comprise hooking means for the return on a wall. In other words, the frame may include a particular geometry to facilitate its implementation on a wall or more generally any type of partition.

En pratique, le montage des baguettes peut être facilité au moyen d'un outil comportant une arête arrondie permettant d'exercer une pression au niveau de la face interne des baguettes.In practice, the assembly of the rods can be facilitated by means of a tool having a rounded edge for exerting pressure at the inner face of the rods.

Un ensemble comportant un châssis et des baguettes ainsi qu'un tel outil peut être fourni avec la toile et vendu de la sorte, donc non assemblé, pour réduire les coûts de main d'oeuvre, de stockage et de manutention.An assembly comprising a frame and chopsticks and such a tool can be provided with the fabric and sold in this way, so unassembled, to reduce labor costs, storage and handling.

L'utilisateur monte alors le cadre et positionne la toile en regard. Un découpage très précis de la toile, combiné avec un positionnement par rapport à un repère sur le châssis, permet de mettre la toile sous une même tension prédéterminée à chaque opération de montage. Ceci est rendu possible par l'utilisation d'une toile réalisée dans un matériau inextensible.The user then climbs the frame and positions the canvas opposite. A very precise cutting of the fabric, combined with a positioning relative to a reference on the frame, allows to put the fabric under the same predetermined tension at each mounting operation. This is made possible by the use of a canvas made of an inextensible material.

Par conséquent, la mise sous tension de la toile ne nécessite aucun réglage de la part de l'utilisateur et est déterminée par la conception même de la toile en fonction du matériau utilisé et de ses dimensions.Therefore, the power of the fabric does not require any adjustment on the part of the user and is determined by the actual design of the fabric depending on the material used and its dimensions.

Manière de décrire l'inventionWay of describing the invention

Comme déjà évoqué, l'invention concerne un dispositif apte à réaliser la mise sous tension et le maintien d'une toile comportant un châssis présentant une rainure, et au moins une baguette déformable.As already mentioned, the invention relates to a device adapted to perform the power and maintenance of a fabric having a frame having a groove, and at least one deformable rod.

Tel que représenté à la figure 1, le dispositif comporte un châssis (2) sur lequel est rapportée une toile (1). La mise sous tension et le maintien de la toile (1) s'effectuent alors par le coincement de la toile (1) au moyen de baguettes (4) à l'intérieur d'une rainure (3).As shown in figure 1 , the device comprises a frame (2) on which is reported a web (1). The tensioning and holding of the fabric (1) is then effected by the jamming of the fabric (1) by means of rods (4) inside a groove (3).

Dans la forme illustrée, les baguettes (4) sont introduites sur la face arrière du châssis (2), mais elles peuvent également l'être sur toutes autres faces du châssisIn the illustrated form, the rods (4) are introduced on the rear face of the frame (2), but they can also be on all other sides of the frame

La figure 1 illustre deux modes de réalisation distincts. Sur l'un des côtés du châssis (2) une baguette déformable (4) s'étend sur toute la longueur de la rainure tandis que sur un autre côté la baguette déformable (4) comporte une pluralités de tronçons indépendants (14,24). Selon l'application et les dimensions du châssis (2) les modes de réalisations peuvent être au choix combinés ou non.The figure 1 illustrates two distinct embodiments. On one side of the frame (2) a deformable rod (4) extends over the entire length of the groove while on another side the deformable rod (4) has a plurality of independent sections (14,24). . Depending on the application and the dimensions of the frame (2) the embodiments may be optionally combined or not.

Des barres de renforts (12) permettent de rigidifier la structure du châssis (2). Ces barres (12) peuvent être solidarisées aux différents tronçons formant le châssis (2) grâce à une pluralité d'agencements (11), ici représentés sous la forme de rainures dans lesquelles un écrou carré peut être inséré. Une vis permet alors de solidariser de manière réversible les barres (12) sur le châssis (2).Reinforcement bars (12) make it possible to stiffen the frame structure (2). These bars (12) can be secured to the different sections forming the frame (2) through a plurality of arrangements (11), here represented in the form of grooves in which a square nut can be inserted. A screw then makes it possible to reversibly connect the bars (12) to the frame (2).

Comme cela ressort de la figure 2, les baguettes (4) déformables présentent une section sensiblement en V orienté vers le fond de la rainure (3). Les baguettes (4) déformables comportent chacune une arête vive (9) destinée à servir de pivot pour autoriser leur déformation, et deux flancs (7, 17) aptes à réaliser le coincement de la toile (1) dans la rainure (3).As is apparent from the figure 2 , the deformable rods (4) have a substantially V-shaped section oriented towards the bottom of the groove (3). The deformable rods (4) each comprise a sharp edge (9) intended to serve as a pivot to allow their deformation, and two flanks (7, 17) adapted to achieve the jamming of the fabric (1) in the groove (3).

Le coincement de la toile (1) à l'intérieur de la rainure (3) est réalisé au moyen des deux flancs (7,17) de la baguette (4) ou (14,24).The wedging of the fabric (1) inside the groove (3) is achieved by means of the two sides (7,17) of the rod (4) or (14,24).

Une portion d'accrochage (13) peut émerger du profilé de manière localisée ou continue sur toute la longueur du profilé pour faciliter l'accrochage du châssis sur une paroi.A hooking portion (13) may emerge from the profile in a localized or continuous manner along the entire length of the profile to facilitate the attachment of the frame on a wall.

Tel que représenté en figure 3, le coincement est obtenu au moyen de deux bourrelets (6,16) réalisés sur les flancs (7,17) de la baguette (4) et par un rétrécissement (5) à l'intérieur de la rainure (3).As represented in figure 3 , the wedging is obtained by means of two beads (6,16) formed on the flanks (7,17) of the rod (4) and by a narrowing (5) inside the groove (3).

La déformation des deux flancs (7,17) s'effectue lors de l'introduction de la baguette (4) à l'intérieur de la rainure (3) par pivotement autour d'une arête vive de la baguette (4).The deformation of the two sidewalls (7, 17) takes place during the introduction of the rod (4) inside the groove (3) by pivoting around a sharp edge of the rod (4).

Des rabats (8) prolongent les deux flancs (7,17) de la baguette (4) à l'extérieur de la rainure, permettant ainsi d'extraire la baguette (4) bloquée à l'intérieur de la rainure (3).Flaps (8) extend the two flanks (7, 17) of the rod (4) outside the groove, thereby extracting the rod (4) locked inside the groove (3).

La rainure permettant de solidariser les barres de renfort (12) présente une ouverture rétrécie permettant le passage d'une vis (18) mais empêchant un écrou carré (19) de sortir de cette rainure. Les différents tronçons du châssis (2) sont ainsi réalisés dans un profilé qui peut présenter une ou plusieurs rainures.The groove for securing the reinforcing bars (12) has a narrowed opening for the passage of a screw (18) but preventing a nut square (19) out of this groove. The different sections of the frame (2) are thus made in a profile which may have one or more grooves.

Il ressort de ce qu'il précède qu'un dispositif conforme à l'invention présente de multiples avantages, notamment :

  • la géométrie de la baguette permet de fournir une élasticité très importante apte à supporter un nombre important de déformations successives ;
  • le mode de fabrication de la baguette déformable est simple à mettre en oeuvre et peu onéreux, tel qu'un procédé par extrusion notamment ;
  • enfin, la densité en mètre d'un tel profilé est très faible, ce qui en fait un élément peu coûteux.
It follows from the foregoing that a device according to the invention has many advantages, in particular:
  • the geometry of the rod provides a very high elasticity able to withstand a large number of successive deformations;
  • the method of manufacturing the deformable rod is simple to implement and inexpensive, such as an extrusion process in particular;
  • finally, the density in meters of such a profile is very low, which makes it an inexpensive element.
