Description

L'invention est relative au domaine de la fixation d'une structure souple, amovible, autour d'un organe, par exemple pour la protection de cet organe qui peut être souple ou rigide, immobile ou articulé, contre les chocs, les intem­péries et les projections de matières grasses, d'agents agressifs ou de peintures.The invention relates to the field of fixing a flexible, removable structure around an organ, for example for the protection of this organ which can be flexible or rigid, immobile or articulated, against shocks, bad weather and splashes of fat, aggressive agents or paints.

L'invention concerne, plus particulièrement, le dispositif de mise en place et de serrage de la structure souple, amovible, autour de l'organe à entourer, par un système de sangles d'accrochage et de boucles de fermeture.The invention relates, more particularly, to the device for positioning and tightening the flexible, removable structure, around the member to be surrounded, by a system of attachment straps and closure loops.

Diverses solutions ont été proposées pour réaliser des systèmes d'accrochage de ceintures ou de protecteurs divers. Dans un grand nombre d'applications, les solutions existantes concernent les articles en cuir, naturel ou synthétique, ou encore en tissu et les dispositifs de fixation sont généra­lement constituées par des boucles rivées dans l'article et des lanières réalisées dans le même matériau que celui de l'article lui-même ou dans un matériau d'une autre nature. Ce type de fixation est particulièrement utilisé pour les chaus­sures, les vêtements ou les éléments souples de protection enroulés autour des organes à entourer. Cependant, aujour- d'hui, pour des raisons d'esthétique, d'entretien, de coût ou de durée de vie, un grand nombre de ces articles évolue vers une réalisation à partir de matériaux polymériques, plasti­ques ou caoutchoucs. L'accrochage de la boucle sur l'article n'est, alors plus possible par rivetage. En effet, les matériaux polymériques présentent souvent - à moins de comporter un élément de renforcement - une fragilité à la déchirure trop importante pour leur permettre de résister aux tractions sur le rivet de fixation de la boucle; par ailleurs, les lanières présentent une déformabilité sous allongement qui ne permet plus d'assurer un serrage correct et les trous de ces lanières ont tendance à s'agrandir au cours du temps ou même à se déchirer.Various solutions have been proposed for making systems for attaching belts or various protectors. In a large number of applications, the existing solutions relate to articles of leather, natural or synthetic, or even of fabric and the fastening devices are generally constituted by loops riveted in the article and straps made of the same material as that of the article itself or in a material of another nature. This type of binding is particularly used for shoes, clothing or flexible protective elements wrapped around the organs to be surrounded. However, today, for reasons of aesthetics, maintenance, cost or lifespan, a large number of these articles are evolving towards production from polymeric materials, plastics or rubbers. The attachment of the loop on the article is no longer possible by riveting. Indeed, polymeric materials often have - unless they include a reinforcing element - a brittle tear that is too great to allow them to resist pulling on the fastening rivet of the buckle; moreover, the strips have a deformability under elongation which no longer ensures correct tightening and the holes in these strips tend to enlarge over time or even to tear.

Pour pallier ces inconvénients, des systèmes différents, c'est-à-dire n'utilisant pas le couple sangle/boucle, tels le dispositif connu sous la marque "Velcro" ou des ensembles à coincement ont été proposés. Il a aussi été décrit, dans le brevet US 4.377.872 de DANIELL, des dispositifs de protection pour jambes d'athlètes, réalisés en plastique et qui se ferment sur eux-mêmes grâce à un système de fentes et de dents sur les bords. Ces systèmes ont tous pour inconvénient une résistance insuffisante aux contraintes engendrées par les sollicitations de certaines applications, sévères, qui font préférer les dispositifs plus résistants de sangles et boucles. Parmi ces dispositifs, il existe diverses variantes de boucles telles celles utilisées dans les ceintures de sécurité pour automobile, décrites notamment dans les brevets GB 2.167.485 de NSK-WARNER, US 4.610.056 de EMMERT ou AU 83.21528 de MOXHAN ou encores les ensembles sangles/boucles comprenant des dispositifs assez complexes tels que ceux proposés dans les brevets CA 1.206. 325 de JOHNSEN & JORGENSEN, FR 2.571.227 de ITW DE FRANCE, EP 195.076 de IWC ou ZA 85.01096 de BYRNE.To overcome these drawbacks, different systems, that is to say not using the strap / buckle pair, such as the device known under the brand "Velcro" or wedging assemblies have been proposed. It has also been described, in US Patent 4,377,872 to DANIELL, protective devices for athletes legs, made of plastic and which close on themselves thanks to a system of slots and teeth on the edges. These systems all have the drawback of insufficient resistance to the stresses generated by the stresses of certain severe applications, which make the more resistant devices of straps and buckles preferred. Among these devices, there are various variants of buckles such as those used in automobile seat belts, described in particular in patents GB 2,167,485 from NSK-WARNER, US 4,610,056 from EMMERT or AU 83,21528 from MOXHAN or even the assemblies. straps / buckles comprising fairly complex devices such as those proposed in patents CA 1.206. 325 from JOHNSEN & JORGENSEN, FR 2,571,227 from ITW DE FRANCE, EP 195,076 from IWC or ZA 85.01096 from BYRNE.

Si ces dispositifs sont efficaces au point de vue de serrage, ils sont tous d'une réalisation compliquée, donc coûteuse. L'analyse de l'art antérieur montre, à l'évidence, que des dispositifs de fixation pour structures souples, destinés à s'adapter par mise en forme - le plus sovent tubulaire - autour d'un organe à entourer présentant, à la fois, une grande sécurité d'attache, une facilité de mise en place et de retrait et une grande longévité, tout en étant d'une réalisation aisée, donc de faible coût, ne sont pas connus.If these devices are effective from the point of view of tightening, they are all of a complicated and therefore expensive construction. The analysis of the prior art clearly shows that fixing devices for flexible structures, intended to adapt by shaping - most often tubular - around an organ to be surrounded presenting, at the times, great attachment security, ease of installation and removal and a long service life, while being easy to make, and therefore of low cost, are not known.

L'objectif de l'invention est donc la mise au point d'un dispositif de fixation, destiné en particulier à la mise en place et au serrage d'une structure souple autour d'un organe, qui soit économique et remplisse les fonctions requises pour l'application, sans présenter les inconvénients des solutions connues.The objective of the invention is therefore the development of a fixing device, intended in particular for the establishment and tightening of a flexible structure around a member, which is economical and fulfills the required functions for the application, without having the drawbacks of known solutions.

Pour ce faire, le dispositif de fixation pour structure souple, objet de l'invention est caractérisé en ce qu'il est constitué d'au moins une sangle d'accrochage, située sur l'un des bords de la zone centrale de la structure souple, qui viendra s'inserrer dans la boucle de fermeture corres­pondante, rigide, située sur le bord opposé de la structure souple, de manière telle qu'elle laisse libre une languette de recouvrement qui évite le contact des boucles de fermeture avec la surface de l'organe entouré et, sur la face externe et au voisinage du bord opposé à celui de la sangle d'accro­chage, au moins un bossage destinée au montage mécanique d'une boucle de fermeture.To do this, the fixing device for flexible structure, object of the invention is characterized in that it consists of at least one hooking strap, located on one the edges of the central zone of the flexible structure, which will be inserted into the corresponding, rigid closing loop, located on the opposite edge of the flexible structure, in such a way that it leaves free a covering tab which avoids the contact of the closure loops with the surface of the surrounded member and, on the external face and in the vicinity of the edge opposite that of the fastening strap, at least one boss intended for the mechanical mounting of a closure loop.

Le dispositif de fixation, objet de l'invention, présente, en outre, une grande facilité de réalisation et surtout de mise en place sur toute structure souple, en particulier réalisée à partir d'un matériau polymérique, les sangles d'accrochage et les bossages de montage des boucles de fermeture étant réalisables au cours du moulage direct de la pièce ou par surmoulage ultérieur des matériaux polymériques constitutifs de ces éléments, - selon un procédé classique de l'industrie de transformation des polymères - et ne nécessite qu'une opération de finition pour le montage des boucles de fermeture.The fastening device which is the subject of the invention also has great ease of production and above all installation on any flexible structure, in particular made from a polymeric material, the fastening straps and the bosses for mounting the closing loops being achievable during direct molding of the part or by subsequent overmolding of the polymeric materials constituting these elements, - according to a conventional process of the polymer transformation industry - and requires only one operation finish for mounting the closure loops.

La zone médiane (2), qui protège le canon, comporte le dispo­sitif de fixation composé, sur l'un des bords de ladite zone médiane, des sangles d'accrochage (3), réalisées en matériau polymérique souple mais de module élevé, le plus souvent pré-­percées de trous (4) destinées à recevoir les ardillons des boucles de fermeture (5) ultérieurement rapportées sur le bord opposé et dans lesquelles lesdites sangles d'accrochage viennent s'inserrer, permettant ainsi au protecteur souple de prendre la forme tubulaire nécessaire à la protection de la jambe du cheval.The central zone (2), which protects the barrel, comprises the fixing device composed, on one of the edges of the said central zone, hooking straps (3), made of flexible polymeric material but of high modulus, the more often pre-drilled with holes (4) intended to receive the barbs of the closure loops (5) subsequently attached to the opposite edge and in which said hooking straps are inserted, thus allowing the flexible protector to take the form tubular necessary to protect the horse's leg.

Le nombre des sangles d'accrochage (3), destinées au serrage de la structure souple, est au moins égal à un. S'il est supérieur à deux, lesdites sangles d'accrochage sont disposées à égale distance (d) sur l'un des bords de la zone médiane (2) pour assurer une bonne répartition du serrage et éviter tout glissement de la structure souple le long de l'organe entouré. Les sangles d'accrochage (3) forment avec le bord de la zone médiane (2), dont elles sont partie inté­grante, un angle muni d'un arrondi (A1) de 90°.The number of attachment straps (3), intended for tightening the flexible structure, is at least equal to one. If it is greater than two, said attachment straps are arranged at equal distance (d) on one of the edges of the median zone (2) to ensure good distribution of the tightening and to prevent any sliding of the flexible structure. along the surrounded organ. The attachment straps (3) form with the edge of the middle zone (2), of which they are an integral part, an angle provided with a rounding (A1) of 90 °.

Sur le bord opposé de la zone médiane (2) et sur la face externe, sont disposés des bossages (6) - ici représentés creux -, en nombre égal à celui des sangles d'accrochage (3), dont la partie débouchante sur la face interne se présente sous la forme de fentes (7), lesdits bossages étant destinés au montage des boucles de fermeture (5), dont une seule a été représentée, sur le bossage central.On the opposite edge of the median zone (2) and on the external face, are arranged bosses (6) - here shown hollow - in a number equal to that of the hooking straps (3), the part of which opens out onto the inner face is in the form of slots (7), said bosses being intended for mounting the closure loops (5), only one of which has been shown, on the central boss.

Les bossages (6) sont placés à une distance du bord de la zone médiane (2) à peine supérieure à la demie-longueur de la boucle de fermeture (5), de manière à ménager le long dudit bord une languette de recouvrement (8), libre de tout élément, qui, lors de la mise en forme, généralement tubulaire, de la structure souple autour de l'organe à entourer, viendra se glisser sous la zone (9) constituant la base des sangles d'accrochage (3). Cette disposition est destinée à éviter, à la surface de l'organe entouré, tout contact avec les boucles de fermeture et à assurer une bonne étanchéité.The bosses (6) are placed at a distance from the edge of the central zone (2) barely greater than the half-length of the closure loop (5), so as to provide along said edge a covering tab (8 ), free of any element, which, during the generally tubular shaping of the flexible structure around the member to be surrounded, will slide under the zone (9) constituting the base of the attachment straps (3 ). This arrangement is intended to avoid, on the surface of the surrounded member, any contact with the closure loops and to ensure good sealing.

La figure 3 illustre une construction particulière d'une sangle d'accrochage, destinée à la mise en forme, généra­lement tubulaire, de la structure souple et au serrage autour de l'organe à entourer, ladite sangle d'accrochage étant réalisée dans une composition polymérique, souple mais de haut module, qui constitue tout ou partie de la structure souple.FIG. 3 illustrates a particular construction of a hooking strap, intended for shaping, generally tubular, of the flexible structure and for tightening around the member to be surrounded, said hooking strap being produced in a composition polymeric, flexible but of high modulus, which constitutes all or part of the flexible structure.

Afin d'éviter toute blessure mécanique, les sangles d'accro­change ne sont jamais placées au contact de la surface de l'organe entouré.In order to avoid mechanical injury, the tether straps are never placed in contact with the surface of the surrounded organ.

La sangle d'accrochage (3) est, avantageusement, rendue inélastique afin que le serrage autour de l'organe entouré garde une valeur constante. Elle doit, également, résister aux efforts de traction qui sont appliqués lors de la mise en place et du serrage de la structure souple.The hooking strap (3) is advantageously made inelastic so that the tightening around the surrounded member keeps a constant value. It must also resist the tensile forces which are applied when the flexible structure is put in place and tightened.

Il est avantageux de réaliser un pré-perçage, au cours de la fabrication, des trous (4) de la sangle d'accrochage (3), trous destinés à recevoir l'ardillon de la boucle de ferme­ture correspondante. Lesdits trous (4) ne doivent pas pouvoir s'élargir ou se déchirer sous l'effet des tractions et des sollicitations en cours d'utilisation.It is advantageous to carry out a pre-drilling, during manufacture, of the holes (4) of the hooking strap (3), holes intended to receive the barb of the corresponding closure loop. Said holes (4) must not be able to widen or tear under the effect of pulls and stresses during use.

Pour répondre à ces trois impératifs d'inélasticité et de résistance mécanique de la sangle d'accrochage (3) et de non déformabilité des trous (4), tout en conservant l'avantage d'une simplicité de réalisation et de mise en place, un renforcement textile (10), du genre canevas, est placé dans la sangle d'accrochage (3).To meet these three imperatives of inelasticity and mechanical strength of the fastening strap (3) and of non-deformability of the holes (4), while retaining the advantage of simplicity of construction and installation, a textile reinforcement (10), of the canvas type, is placed in the hooking strap (3).

Du type à mailles ouvertes, il permet que se créent, à travers lesdites mailles, des liaisons polymériques garan­tissant ainsi la sangle d'accrochage (3) contre toute possi­bilité de délaminage ou de décollage sans nécessiter d'adhé­risation du renforcement textile (10), préalablement à sa mise en place dans la sangle d'accrochage.Of the open mesh type, it allows polymeric bonds to be created through said meshes, thus guaranteeing the attachment strap (3) against any possibility of delamination or take-off without requiring adhesion of the textile reinforcement (10), prior to its installation in the hooking strap.

De même, grâce à ses mailles ouvertes, le renforcement textile (10) se prêtera aisemment au perçage des trous (4) au cours de l'opération de fabrication et évitera, en cours d'utilisation, toute propagation des déchirures à partir desdits trous (4) qui, sans ce renforcement textile, consti­tueraient, en eux-mêmes, des amorces de déchirures.Likewise, thanks to its open meshes, the textile reinforcement (10) will easily lend itself to drilling the holes (4) during the manufacturing operation and will prevent, during use, any propagation of tears from said holes. (4) which, without this textile reinforcement, would constitute, in themselves, incipient tears.

Le renforcement textile (10) est généralement placé, dans la sangle d'accrochage (3), au voisinage de la moitié de l'épaisseur de ladite sangle d'accrochage, pour des raisons de facilité de réalisation mais, sa seule fonction étant le renforcement de cette zone, sa position dans l'épaisseur de la sangle d'accrochage (3) est sans importance.The textile reinforcement (10) is generally placed, in the fastening strap (3), in the vicinity of half the thickness of said fastening strap, for reasons of ease of production but, its only function being the reinforcement of this area, its position in the thickness of the hooking strap (3) is unimportant.

Le renforcement textile (10) peut, avantageusement, comporter un talon (11) qui le prolonge dans la zone (9) constituant la base des sangles d'accrochage (3) et augmente ainsi son efficacité de renforcement et d'inextensibilité.The textile reinforcement (10) may advantageously include a heel (11) which extends it into the zone (9) constituting the base of the attachment straps (3) and thus increases its reinforcement and non-extensibility efficiency.

La figure 4 représente, en coupe le détail d'une réalisation particulière d'un bossage destiné à la fixation d'une boucle de fermeture. Il s'est avéré intéressant, en effet, pour des raisons de facilité de montage des boucles de fermeture, de réaliser des bossages creux, à parois latérales de faible épaisseur (12), facilement perçables par des boucles de fermeture, dont les extrémités des cavaliers sont pointues.Figure 4 shows, in section the detail of a particular embodiment of a boss intended for fixing a closure loop. It has proved to be interesting, in fact, for reasons of ease of mounting the closure loops, to produce hollow bosses, with thin side walls (12), easily pierced by closure loops, the ends of the jumpers are sharp.

Les bossages (6) sont disposés sur la face externe de la structure souple, au voisinage du bord de la zone médiane (2) opposé à celui comportant les sangles d'accrochage, leur nombre étant égal à celui desdites sangles d'accrochage.The bosses (6) are arranged on the external face of the flexible structure, in the vicinity of the edge of the median zone (2) opposite to that comprising the attachment straps, their number being equal to that of said attachment straps.

La vue 4a montre que la partie creuse (13) du bossage (6) présente une forme parallélépipédique à sommet arrondi.View 4a shows that the hollow part (13) of the boss (6) has a parallelepiped shape with a rounded top.

La vue 4b, qui est une coupe transversale du bossage (6) met en évidence la largeur (f) de la partie creuse (13) dudit bossage (6) qui est de l'ordre de 0,10 à 0,20 fois le diamètre du bossage (6) et sa hauteur (h) qui est au moins égale à 1,1 fois l'épaisseur de la zone médiane (2), afin de permettre le perçage de la paroi latérale amincie (12) par la boucle de fermeture auto-percante.View 4b, which is a cross section of the boss (6), highlights the width (f) of the hollow part (13) of said boss (6) which is of the order of 0.10 to 0.20 times the diameter of the boss (6) and its height (h) which is at least equal to 1.1 times the thickness of the middle zone (2), in order to allow the thinned side wall (12) to be pierced by the self-piercing closure loop.

La vue 4c, couple longitudinale du bossage creux (6), montre la longueur (F) de la partie creuse (13) dudit bossage qui est comprise entre 0,80 et 0,95 fois la largeur à la base (G) dudit bossage.View 4c, longitudinal couple of the hollow boss (6), shows the length (F) of the hollow part (13) of said boss which is between 0.80 and 0.95 times the width at the base (G) of said boss .

La figure 5 détaille une constitution particulière d'une boucle de fermeture, qui est auto-perçante pour se monter aisemment dans les bossages creux et assurer, ensuite, la mise en forme, généralement tubulaire, et le serrage de la structure souple, sur l'organe à entourer, par l'intermé­diaire des sangles d'accrochage.Figure 5 details a particular constitution of a closure loop, which is self-piercing to easily mount in the hollow bosses and then ensure the shaping, generally tubular, and the tightening of the flexible structure, on the 'organ to be surrounded, by means of attachment straps.

La boucle de fermeture (5), rigide, en général métallique, comporte un cadre (14), de forme générale rectangulaire, et une barrette centrale (15) servant d'axe pour le montage de l'ardillon (16) et du cavalier (17).The closing loop (5), rigid, generally metallic, comprises a frame (14), of generally rectangular shape, and a central bar (15) serving as an axis for mounting the barb (16) and the rider (17).

Afin de faciliter son montage dans les bossages creux, la boucle de fermeture (5) présente la particularité d'avoir les extrémités (18) du cavalier (17) pointues, de manière à pouvoir, sous l'effet de serrage exercé au montage par une simple pince, perforer les parois latérales amincies du bossage creux et à obliger le cavalier (17) à venir au contact du sommet arrondi de la partie creuse interne au bossage sur toute la longueur des bras (19) dudit cavalier (17), réalignés par déformation au montage, afin d'assurer une meilleure répartition des contraintes.In order to facilitate its mounting in the hollow bosses, the closing loop (5) has the particularity of having the ends (18) of the jumper (17) pointed, so as to be able, under the clamping effect exerted during mounting by a simple pliers, to perforate the thinned side walls of the hollow boss and to force the rider (17) to come into contact with the rounded top of the hollow part internal to the boss over the entire length of the arms (19) of said rider (17), realigned by deformation during assembly, in order to ensure a better distribution of stresses.

Es cas de sollicitation importante ou de choc, la composition polymérique souple de haut module constituant le bossage se déformera, son module étant inférieur à celui du matériau constitutif de la boucle de fermeture (5), empêchant ainsi toute ouverture des bras (19) du cavalier (17) qui aurait entraîné la désolidarisation de la boucle de fermeture (5) et du bossage (6).In the event of significant stress or shock, the flexible, high-modulus polymer composition constituting the boss will deform, its modulus being less than that of the material constituting the closure loop (5), thus preventing any opening of the arms (19) of the jumper (17) which would have led to the separation of the closure loop (5) and the boss (6).

La boucle de fermeture auto-perçante, peut, en outre, comme illustré, comporter, au voisinage de son centre, deux picots de guidage (20) destinés à limiter le déplacement de l'ardillon (16), en le maintenant en position centrale, pour faciliter son insertion dans les trous de la sangle d'accrochage correspondante.The self-piercing closing loop may, in addition, as illustrated, comprise, in the vicinity of its center, two guide pins (20) intended to limit the movement of the barb (16), while maintaining it in the central position , to facilitate its insertion into the holes of the corresponding hooking strap.

La figure 6 décrit un mode de réalisation d'une boucle de fermeture (5) qui permet d'améliorer la liaison entre le cavalier (17) et le cadre (14) et offre la possibilité d'une fabrication, en série, à faible coût.FIG. 6 describes an embodiment of a closure loop (5) which improves the connection between the rider (17) and the frame (14) and offers the possibility of mass production, at low cost. cost.

Les vues 6a, 6b et 6c schématisent les opérations de pre-­enroulage et de montage du cavalier (17) sur la barrette centrale (15) de la boucle de fermeture (5).Views 6a, 6b and 6c show schematically the pre-winding and mounting operations of the jumper (17) on the central bar (15) of the closing loop (5).

La vue 6a représente la pré-forme (27) du cavalier et la flèche (S) illustre le sens dans lequel doit se faire le pré-­enroulage.View 6a shows the pre-form (27) of the jumper and the arrow (S) illustrates the direction in which the pre-winding must be done.

La vue 6b représente la forme prise par le cavalier (17) après l'opération de pré-enroulage de la partie (28).View 6b shows the shape taken by the rider (17) after the pre-winding operation of the part (28).

La vue 6c montre le cavalier (17) inserré sur la barrette centrale (15) sur laquelle il est alors refermé de manière à laisser un jeu suffisant pour assurer la libre rotation dudit cavalier (17) autour de l'axe constitué par la barrette centrale (15) du cadre (14) de la boucle de fermeture.View 6c shows the jumper (17) inserted on the central bar (15) on which it is then closed so as to leave sufficient play to ensure the free rotation of said jumper (17) around the axis formed by the central bar (15) of the frame (14) of the closure loop.

La boucle de fermeture ainsi réalisée est en tous points conforme à celle illustrée sur la figure 5.The closure loop thus produced conforms in all respects to that illustrated in FIG. 5.

La figure 7 illustre une variante du dispositif de fixation, dans laquelle les sangles d'accrochage planes, précédemment décrites, sont remplacées par des sangles d'accrochage crantées (21), venant prendre appui sur des surépaisseurs (22) disposées sur le bord opposé de la structure souple, surépaisseurs jouant le rôle des bossages du dispositif de fixation précédemment décrit et pouvant, comme lesdits bossages, comporter une cavité (non représentée) pour faciliter le montage des boucles de fermeture (23) qui, dans la variante utilisant les sangles d'accrochage crantées, ne comportent pas d'ardillon.FIG. 7 illustrates a variant of the fastening device, in which the flat hooking straps, previously described, are replaced by notched hooking straps (21), coming to bear on thickeners (22) arranged on the opposite edge of the flexible structure, extra thicknesses playing the role of the bosses of the fixing device described above and which, like said bosses, may include a cavity (not shown) for facilitate the mounting of the closure loops (23) which, in the variant using the notched hooking straps, do not have a barb.

Les extrémités (24) des boucles de fermeture sans ardillon (23) seront, avantageusement, pointues afin de rendre lesdites boucles de fermeture auto-perçantes pour faciliter leur introduction dans les parois amincies des surépaisseurs (22), creuses.The ends (24) of the barbed-free closure loops (23) are advantageously pointed in order to make said closure loops self-piercing to facilitate their introduction into the thinned walls of the extra thicknesses (22), hollow.

La mise en forme, généralement tubulaire, et le serrage de la structure souple autour de l'organe à entourer se feront par traction sur les extrémités (25) des sangles d'accrochage crantées (21) les crans (26) empêchant, par blocage méca­nique contre les boucles de fermeture sans ardillon (23), le desserrage desdites sangles d'accrochage crantées (21), cependant desserrables à la main par passage des boucles de fermeture sans ardillon (23) par dessus les crans (26).The shaping, generally tubular, and the tightening of the flexible structure around the member to be surrounded will be done by traction on the ends (25) of the notched hooking straps (21) the notches (26) preventing, by blocking mechanical against the barbed closure loops (23), the loosening of said notched hooking straps (21), however can be released by hand by passing the barbed closure loops (23) over the notches (26).

Les sangles d'accrochage crantées (21) pourront être rendues inextensibles par un renforcement textile du même type que celui utilisé pour les sangles d'accrochage planes.The notched fastening straps (21) can be made inextensible by a textile reinforcement of the same type as that used for the flat fastening straps.

Le dispositif de fixation pour structure souple, objet de l'invention, est réalisé par vulcanisation ou surmoulage, dans un moule, sous presse, selon un procédé couramment utilisé dans l'industrie de transformation des polymères.The fixing device for flexible structure, object of the invention, is produced by vulcanization or overmolding, in a mold, under press, according to a process commonly used in the polymer processing industry.

Dans un moule présentant la forme et les dimensions adé­quates, sont disposés la structure souple ou ses composants ainsi que les renforcements textiles et les matériaux poly­mériques de réalisation des bossages ou des surépaisseurs qui peuvent - si nécessaire - avoir reçu, au préalable, un traitement d'adhérisation destiné à assurer leur liaison intime avec le (ou les) matériau(x) constituant la structure souple.In a mold having the appropriate shape and dimensions, are arranged the flexible structure or its components as well as the textile reinforcements and the polymeric materials for producing the bosses or the extra thicknesses which may - if necessary - have received, beforehand, a treatment of adhesion intended to ensure their intimate connection with the material (s) constituting the flexible structure.

La mise sous pression et le traitement thermique provoquent la mise en forme définitive du dispositif de fixation de la structure souple, tout en assurant la liaison intime des composants entre eux. De par la conception du moule et la disposition des composants, les compsitions polymériques souples de haut module constituent, au moins, la (ou les) sangle(s) d'accrochage qui permet(tent) le serrage autour de la partie de l'organe à protéger et le (ou les) bossage(s) ou la (ou les) surépaisseur(s) sur le(s) quel(s) viendra (ou viendront), ultérieurement, au cours de l'opération de fini­tion, se monter la (ou les) boucle(s) de fermeture dans laquelle (ou lesquelles) s'engage(nt) la (ou les) sangle(s) d'accrochage.The pressurization and the heat treatment cause the final fixing device of the flexible structure, while ensuring the intimate connection of the components together. Due to the design of the mold and the arrangement of the components, the flexible, high-modulus polymer compositions constitute, at least, the (or) strap (s) of attachment which allows (tent) the tightening around the part of the organ to be protected and the (or) boss (es) or (or) extra thickness (es) on (s) which (s) will come (or will come), later, during the finishing operation, mount the closing loop (s) into which the hooking strap (s) engage (s).

Après démoulage de la structure souple, une opération de finition permet la mise en place de chacune des boucles de fermeture, avec ou sans ardillon, sur le bossage ou la suré­paisseur prévu à cet effet.After demolding the flexible structure, a finishing operation allows the establishment of each of the closure loops, with or without barbs, on the boss or the extra thickness provided for this purpose.

L'opération de finition est grandement facilitée, dans la variante de l'invention qui comporte le type de bossage ou de surépaisseur creux et utilise le type de boucle de fermeture auto-perçante, puisqu'une simple pression sur les bras de ladite boucle de fermeture, à l'aide d'une pince, provoque la perforation des parois amincies du bossage ou de la surépais­seur et le serrage des bras de la boucle de fermeture.The finishing operation is greatly facilitated, in the variant of the invention which includes the type of hollow boss or allowance and uses the type of self-piercing closure loop, since a simple pressure on the arms of said loop closing, using pliers, causes the perforation of the thinned walls of the boss or the extra thickness and the tightening of the arms of the closing loop.

Le dispositif de fixation d'une structure souple autour d'un organe à entourer, objet de l'invention, offre, par rapport aux solutions connues de l'art antérieur, les avantages suivants :
- il est d'une réalisation très économique puisqu'il est produit en une seule opération de moulage ou de surmoulage, suivie d'une finition, qui peut être très simplifiée, consistant dans le montage de la boucle de fermeture ;
- il assure une bonne étanchéité grâce à la languette de recouvrement placée au niveau des sangles d'accrochage, sans provoquer de blessure mécanique puisque ladite languette de recouvrement évite tout contact de la boucle de fermeture, rigide, avec la surface de la partie de l'organe entouré;
- il est facile à mettre en place sur l'organe à entourer et à retirer,
- il ne peut glisser puisque la sangle d'accrochage peut être rendue inextensible et que les trous de passage de l'ardillon de la boucle de fermeture ne peuvent s'agrandir en cours d'utilisation.The device for fixing a flexible structure around a member to be surrounded, object of the invention, offers, compared to solutions known from the prior art, the following advantages:
- It is very economical to produce since it is produced in a single molding or overmolding operation, followed by a finish, which can be very simplified, consisting in mounting the closure loop;
- it ensures a good seal thanks to the cover tab placed at the level of the attachment straps, without causing mechanical injury since said tab covering avoids any contact of the rigid closure loop with the surface of the part of the surrounded member;
- it is easy to put on the organ to be surrounded and removed,
- It can not slip since the hooking strap can be made inextensible and that the through holes of the barb of the closure loop cannot enlarge during use.

La présente invention s'applique à la fixation de structures souples aussi bien sur des organes rigides que souples, immo­biles qu'articulés ou mobiles.The present invention applies to the fixing of flexible structures as well on rigid as flexible organs, immobile as articulated or mobile.

L'homme de l'art peut, bien entendu, apporter au dispositif de fixation pour structure souple et à ses variantes, décrits à titre d'exemples non limitatifs, diverses modifications sans sortir du cadre de l'invention.Those skilled in the art can, of course, make various modifications to the fixing device for flexible structure and to its variants, described by way of non-limiting examples, without going beyond the ambit of the invention.
