Abstract

The securing device according to the invention uses a series of folds (5) on the periphery of the canvas (4) which delimit a radial passage into which can be fitted the end (6) of a rod (3). The cross section of the passage formed by each fold (5) decreases in the direction of insertion of the rods, while the end (6) of the rods (3) has a straight cross section, its area being greater than that of the smallest cross section of the passage formed by the fold (5). The invention is especially applicable in the manufacture of umbrellas.

Description

DISPOSITIF DE FIXATION D'UNE TOILE EN MATERIAU DEFORMABLE SUR UN SUPPORT FORME DE BALEINES FLEXIBLES. DEVICE FOR FIXING A CANVAS OF DEFORMABLE MATERIAL ON A SUPPORT FORMED BY FLEXIBLE WHALES.
La présente invention concerne un dispositif de fixation d'une toile en matériau déformable sur un support formé de baleines flexibles* The present invention relates to a device for fixing a canvas of deformable material on a support formed by flexible ribs *
Elle s'applique plus particulièrement, mais non exclusi¬ vement, à la réalisation de parapluies.It applies more particularly, but not exclusively, to the production of umbrellas.
On rappelle à ce sujet qu'un parapluie de type classique est formé d'un mât dont une extrémité est prolongée par un manche, tandis que l'autre extrémité forme un embout sur lequel est articulée une pluralité de baleines radiales mobiles dans des plans axiaux et sur laquelle est fixée la toile de parapluie. Le long du mât est mon¬ tée coulissante une douille reliée à chacune des baleines par un arc boutant respectif dont 1'une des extrémités vient s'articuler sur ladite douille, tandis que l'autre extrémité vient s'articuler dans la région centrale de ladite baleine. Des moyens d'encliquetage sont également prévus sur le mât et sur la douille de manière à assurer le maintien du parapluie en position ouverte ou en posi¬ tion fermée.On this subject, it is recalled that an umbrella of the conventional type is formed of a pole, one end of which is extended by a handle, while the other end forms an end-piece on which is articulated a plurality of radial whales movable in axial planes. and on which is fixed the umbrella cloth. Along the mast is a sliding bush, a bushing connected to each of the whales by a respective flying bow, one of the ends of which is articulated on the said bushing, while the other end is articulated in the central region of said whale. Latching means are also provided on the mast and on the socket so as to maintain the umbrella in the open position or in the closed position.
Habituellement, la fixation de la toile de parapluie sur les baleines s'effectue par couture de place en place le long des baleines, le maintien axial de la toile le long de ces dernières étant assuré grâce à un embout monté sur les extrémités des baleines et présentant un orifice dans lequel passe le fil servant à la couture de la toile.Usually, the fixing of the umbrella canvas on the whales is done by sewing from place to place along the whales, the axial maintenance of the canvas along of the latter being ensured by means of a nozzle mounted on the ends of the whales and having an orifice through which passes the thread used for sewing the canvas.
On constate que cette solution classique est particuliè¬ rement coûteuse, tant par le nombre de pièces qu'elle fait intervenir, que du fait de la complexité du montage.It can be seen that this conventional solution is particularly expensive, both in terms of the number of parts it involves, and due to the complexity of the assembly.
En outre, cette solution ne convient pas à tous les types de toile qu'il serait souhaitable d'utiliser et, en par¬ ticulier, des toiles consistant en des films de matière plastique pour lesquels les coutures sont exclues.In addition, this solution is not suitable for all types of canvas that it would be desirable to use and, in particular, fabrics consisting of plastic films for which the seams are excluded.
L'invention a plus particulièrement pour but de supprimer ces inconvénients et d'apporter une solution au problème de la fixation d'une toile même dans le cas où celle-ci est réalisée en un matériau .facilement déformable, montée sous tension sur des baleines.The object of the invention is more particularly to eliminate these drawbacks and to provide a solution to the problem of fixing a canvas even in the case where it is made of a material that is easily deformable, mounted under tension on whales. .
Bien entendu, une telle solution implique la résolution des problèmes relatifs à la faible résistance mécanique du film et, en particulier, aux déformations rémanenres (étirements) qui demeurent sur les films après qu' ls aient subi des contraintes en traction.Of course, such a solution involves solving the problems relating to the low mechanical strength of the film and, in particular, to the residual deformations (stretching) which remain on the films after they have been subjected to tensile stresses.
Pour parvenir à ces résultats, l'invention propose un dispositif de fixation faisant intervenir une série de fronces radiales réalisées à la périphérie de la toile et délimitant chacune un passage radial dans lequel l'extrémité d'une baleine peut venir s'engager.To achieve these results, the invention provides a fixing device involving a series of radial pleats produced at the periphery of the fabric and each delimiting a radial passage in which the end of a whale can engage.
Selon l'invention, ce dispositif est plus particulière¬ ment caractérisé en ce que la section de passage autorisé par chacune des fronces va en décroissant dans le sens d'engagement des baleines, et en ce que l'extrémité des baleines présente une section droite dont 1'aire est supérieure à celle de la plus petite section de passage autorisé de la fronce, de manière à ce que, lors d'un premier engagement à force de la baleine dans la fronce, celle-ci vienne épouser au moins partiellement la forme de 1'extrémité de la baleine et retienne axialement cette dernière.According to the invention, this device is more particularly characterized in that the passage section authorized by each of the gathers decreases in the direction of engagement of the whales, and in that the end of the whales has a straight section the area of which is greater than that of the smallest authorized passage section of the pleat, so that, during a first force engagement of the whale in the gathered, it comes to marry at least partially the shape of the end of the whale and axially retains the latter.
Avantageusement, la forme de la fronce et celle de 1'extrémité de la baleine seront prévues de manière à ce que la surface de contact entre ces deux éléments soit aussi grande que possible et que 1'on évite ainsi la pré- sence de zones de la toile sujettes à des contraintes élevées et risquant, de ce fait, de faire l'objet de déchirures.Advantageously, the shape of the pleat and that of the end of the whale will be provided so that the contact surface between these two elements is as large as possible and that the presence of areas of contact is thus avoided. the canvas subject to high stresses and therefore likely to be torn.
Un mode de réalisation de l'invention sera décrit ci- après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels :An embodiment of the invention will be described below, by way of nonlimiting example, with reference to the appended drawings in which:

La figure 7 est une coupe dans le plan P2 de la fronce représentée figure 6.FIG. 7 is a section in the plane P2 of the pleat shown in FIG.
Le parapluie illustré figure 1, dont on ne voit que le dessus, fait intervenir un mât 1 dont l'extrémité supé- rieure forme un embout 2 sur lequel est articulée une pluralité de baleines radiales 3 sur laquelle est fixée la toile 4 de parapluie.The umbrella illustrated in FIG. 1, the top of which can only be seen, involves a mast 1, the upper end of which forms a nozzle 2 on which a plurality of radial ribs 3 is hinged, on which the umbrella fabric 4 is fixed.
Un tel parapluie peut avantageusement consister en celui qui se trouve décrit dans la demande de brevet FR-89 04237, déposée le 31 mars 1989, aux noms conjoints de Hugues THIERION de MONCLIN'et Patrice LALONDE.Such an umbrella can advantageously consist of that which is described in patent application FR-89 04237, filed on March 31, 1989, in the joint names of Hugues THIERION de MONCLIN ' and Patrice LALONDE.
A l'état déployé, la toile 4, tendue par les baleines, présente la forme d'une calotte à facettes, le nombre de facettes (ici huit) étant égal au nombre de baleines 3.In the deployed state, the fabric 4, stretched by the whales, has the shape of a faceted cap, the number of facets (here eight) being equal to the number of whales 3.
La toile 4 consiste ici en un film en matière plastique, de forme circulaire (ou, éventuellement, octogonale). Elle se trouve fixée à la structure du parapluie, d'une part, au niveau de l'embout 2 par des moyens appropriés qui ne rentrent pas dans le cadre de la présente inven¬ tion et, d'autre part, au niveau de sa périphérie, grâce à des fronces radiales 5 de faible longueur, dans les- quelles s'engagent les extrémités des baleines 3.The canvas 4 here consists of a plastic film, circular (or, possibly, octagonal). It is fixed to the structure of the umbrella, on the one hand, at the end piece 2 by appropriate means which do not come within the scope of the present invention and, on the other hand, at its periphery, thanks to radial gathers 5 of short length, into which the ends of the whales 3 engage.
Dans cet exemple, les baleines 3, réalisées en matière plastique moulée ou extrudée, se présentent sous la forme de tiges de section droite en T qui comprennent une extrémité plate 6 à bout arrondi prolongeant la partie transversale du T. Comme ceci est visible sur la figure 4, les fronces 5 sont réalisées de manière à délimiter un passage P dont la section décroît progressivement depuis l'orifice Si situé vers le centre du parapluie jusqu'à l'orifice S2 situé vers l'extérieur.In this example, the ribs 3, made of molded or extruded plastic, are in the form of rods of cross section in T which include a flat end 6 with rounded end extending the transverse part of the T. As can be seen in FIG. 4, the gathers 5 are produced so as to delimit a passage P, the section of which decreases progressively from the orifice Si situated towards the center of the umbrella up to the orifice S2 situated towards the outside.
Les fronces 5 sont réalisées en formant un repli axial autour d'un axe de pliage YY' et en formant sur les deux parties repliées 1'une contre 1'autre deux traits de sou- dure, à savoir : un premier trait de soudure 7 (ou de couture) légèrement oblique par rapport à 1'axe YY' du pli, de manière à ce que la toile 4 présente à cet endroit une forme tubulaire qui délimite un passage P présentant les caractéristiques précédemment évoquées, et un deuxième trait de soudure 8 (ou de couture) situé au- dessous du premier, qui est sensiblement parallèle à l'axe YY' de pliage.The gathers 5 are produced by forming an axial fold around a folding axis YY 'and by forming on the two folded parts, one against the other, two weld lines, namely: a first weld line 7 (or sewing) slightly oblique with respect to the axis YY ′ of the fold, so that the fabric 4 has at this point a tubular shape which delimits a passage P having the characteristics mentioned above, and a second weld line 8 (or sewing) located below the first, which is substantially parallel to the axis YY 'of folding.
La raison pour laquelle on utilise deux traits de soudure 7, 8 alors qu'un seul aurait pu suffire, tient au fait que 1'on cherche à dissocier les contraintes résultant de 1'engagement des baleines 3 à 1'intérieur des fronces 5, des contraintes exercées par la toile 4 sur les baleines 3 (qui provoquent, éventuellement, le fléchissement des- dites baleines 3). En outre, le second trait de soudure 8 détermine la hauteur de la calotte formée par la toile 4.The reason why two weld lines 7, 8 are used when only one could have been sufficient, is due to the fact that one seeks to dissociate the stresses resulting from the engagement of the whales 3 inside the gathers 5, stresses exerted by the fabric 4 on the whales 3 (which possibly cause the said whales 3 to bend). In addition, the second weld line 8 determines the height of the cap formed by the fabric 4.
Dans l'exemple représenté sur les figures 4 et 6, la sec¬ tion de passage Si à l'entrée de la fronce 5 (côté inté- rieur) correspond sensiblement à la section de 1'extrémité de la baleine.In the example shown in FIGS. 4 and 6, the passage section Si at the entrance to the pleat 5 (interior side) corresponds substantially to the section of the end of the whale.
Ainsi, lors de la fixation de la toile sur les baleines, on engage à force 1'extrémité 6 de chaque baleine 3 dans le passage d'une fronce 5 correspondante, en provoquant la déformation du film de matière plastique qui vient alors épouser étroitement la forme aplatie de 1'extrémité 6. De préférence, les dimensions des baleines 3 sont prévues de manière à ce qu'elles ne traversent pas la fronce 5, mais qu'il subsiste au bout de la fronce 5 une région non occupée 9 qui forme en quelque sorte une butée empêchant le coulissement de la fronce le long de la baleine et qui assure un auto-coincement toile/baleine chaque fois que les contraintes axiales exercées provoquent une nouvelle déformation de la fronce 5.Thus, during the fixing of the canvas on the whales, the end 6 of each whale 3 is forcibly engaged in the passage of a corresponding gathered 5, causing the deformation of the plastic film which then closely follows the flattened shape of the end 6. Preferably, the dimensions of the ribs 3 are provided so that they do not pass through the pleat 5, but that there remains at the end of the pleat 5 an unoccupied region 9 which somehow forms a stop preventing sliding of the pleat along the whalebone and which ensures canvas / whale self-jamming each time the axial stresses exerted cause a new deformation of the pleat 5.
On constate en outre que, grâce à une telle disposition, la surface de fixation entre la toile 4 et les baleines 3 est relativement importante et que 1'on réduit ainsi considérablement les risques de déchirure au niveau de cette fixation.It is further noted that, thanks to such an arrangement, the fixing surface between the fabric 4 and the ribs 3 is relatively large and that the risks of tearing at this fixing are thus considerably reduced.
Bien entendu, le dispositif de fixation précédemment décrit s'applique aussi bien aux toiles réalisées en un matériau déformable qu'aux toiles classiques de para- pluie. Toutefois, il convient de préciser que ce disposi¬ tif convient particulièrement bien aux toiles réalisées en une seule et même pièce.Of course, the previously described fixing device applies equally to fabrics made of a deformable material as to conventional rain cloths. However, it should be noted that this device is particularly suitable for fabrics produced in a single piece.
En outre, selon la nature du matériau utilisé, les sus- dits traits de soudure 7 et 8 pourront être remplacés par des traits de collage, de couture ou analogue. In addition, depending on the nature of the material used, the aforementioned weld lines 7 and 8 may be replaced by bonding, sewing or similar lines.
