Description

La présente invention concerne un dispositif d'ancrage de structure souple, dénommé ralingue. La ralingue est un dispositif bien connu en marine. Il s'agit historiquement d'un cordage cousu en bordure d'une voile ou sur un filet, destiné à les renforcer. Par analogie, on appellera ralingue un élément en surépaisseur fixé en lisière d'une structure souple pour faciliter sa préhension, son maintien, ou sa fixation, tout en la renforçant. Dans le cadre de la présente invention, il sera essentiellement question de la fixation, qu'on appellera alors ancrage. La démarche consistera à optimiser la forme de la ralingue afin de permettre une bonne distribution et une totale reprise des efforts transmis par la structure souple sur son ancrage.The present invention relates to a device for anchoring flexible structure, called headline. The headliner is a well known device in marine. This is historically a rope sewn on the edge of a sail or on a net, intended to strengthen them. By analogy, it will call ralingue a thickened element attached to the edge of a flexible structure to facilitate its gripping, holding, or fixing, while strengthening. In the context of the present invention, it will be essentially a question of fixing, which will then be called anchoring. The approach will consist in optimizing the shape of the headline to allow a good distribution and a total recovery of the forces transmitted by the flexible structure on its anchorage.

Nous considérerons une structure souple (1), qui pourra être constituée d'un textile, éventuellement enduit d'élastomère ou de plastomère, ou d'un tissage ou maillage textile ou métallique. Nous considérerons que cette structure souple sera soumise à des efforts de traction qui devront être transmis à un dispositif d'ancrage (2), afin d'assurer la fixation de la dite structure. Le dispositif d'ancrage sera constitué essentiellement de la ralingue. Dans le cadre de la présente invention, la ralingue (3) consiste, plus spécifiquement, en un profil formant bourrelet, qu'on appellera âme (4), prisonnier dans un ourlet (5), (Figure 1), qui sera inséré dans un profilé receveur (6), ou pincé par un dispositif faisant office de receveur. La lisière, et plus particulièrement l'âme, viendront buter sur les parties adéquates du receveur , lorsque la structure souple (1) sera soumise à une tension T, et le dispositif (2) assurera alors l'ancrage de la dite structure. (Figure 2).We will consider a flexible structure (1), which may consist of a textile, optionally coated with elastomer or plastomer, or a textile or metal mesh or mesh. We will consider that this flexible structure will be subjected to traction forces which must be transmitted to an anchoring device (2), in order to ensure the fixing of said structure. The anchoring device will consist essentially of the rope. In the context of the present invention, the rope (3) consists, more specifically, in a bead profile, which will be called core (4), prisoner in a hem (5), (Figure 1), which will be inserted in a receiving section (6), or pinched by a device acting as a receiver. The selvedge, and more particularly the soul, will abut on the adequate parts of the receiver, when the flexible structure (1) will be subjected to a tension T, and the device (2) will then ensure the anchoring of said structure. (Figure 2).

D'une façon prévisible, lors de la mise en tension de la structure souple (1), il se produira une déformation de la ralingue, avec ouverture de l'ourlet, au niveau de la « bouche » (7) du profilé receveur. (Figure 3). Il s'en suivra des contraintes d'arrachement ou de pelage sur l'ourlet (5), et des déformations, par écrasement, difficilement maîtrisables, de l'âme (4), si elle est souple, ou de l'ourlet, dans le cas contraire. La présente invention a pour but de pallier ces inconvénients. Afin d'offrir une répartition homogène et optimale des efforts résultant du « butonnage » de l'ourlet (5) garni de son âme (4), sur le profilé receveur (6), l'âme présentera une surface d'appui prismatique formée principalement de deux surfaces sensiblement planes (8) formant un angle dièdre correspondant à celui des surfaces de contact (9) du profilé receveur. (Figure 4). On reconstituera ainsi une particularité, bien connue en mécanique, du « coin », utilisé comme système de blocage linéaire , tout comme le cône morse pour un emmanchement conique. Selon un aspect avantageux de l'invention, le profilé receveur sera constitué d'au moins deux parties indépendantes dont le démontage facilitera la mise en place, et qui pourront être ajustées et liaisonnées par un système mécanique simple, par vissage par exemple. (Figure 5). Selon un aspect avantageux de l'invention, la cavité interne (10) du profilé receveur présentera une section légèrement plus grande que celle de la ralingue (3), afin de faciliter la mise en place , et en permettant une déformation de celle-ci lors de la mise en charge. Selon un aspect avantageux de l'invention, l'âme sera constituée d'un profilé élastomère obtenu par extrusion. Selon un autre aspect de l'invention, l'âme pourra être reconstituée a posteriori, par remplissage de la cavité de l'ourlet par un produit plus ou moins fluide , mais durcissant, du type résine, ou pouvant se polymériser pour former une mousse de polymère ou élastomère. Ce produit, après changement d'état, prendra une forme propre et la conservera à la déformation près, et occupera l'espace disponible dans la cavité interne (10) du profilé receveur, en épousant les formes des surfaces de contact (8) du profilé receveur .Predictably, during the tensioning of the flexible structure (1), there will occur a deformation of the headline, with opening of the hem, at the "mouth" (7) of the receiver profile. (Figure 3). It will follow stresses of tearing or peeling on the hem (5), and deformations, by crushing, difficult to control, the soul (4), if it is flexible, or the hem, on the other hand. The present invention aims to overcome these disadvantages. In order to offer a homogeneous and optimal distribution of efforts resulting from the "buttressing" of the hem (5) lined with its core (4), on the receiving profile (6), the core will present a prismatic bearing surface formed mainly two substantially planar surfaces (8) forming a dihedral angle corresponding to that of the contact surfaces (9) of the receiving profile. (Figure 4). We will reconstruct a feature, well known in mechanics, the "corner" used as a linear locking system, as the Morse taper for a conical fitting. According to an advantageous aspect of the invention, the receiving profile will consist of at least two independent parts whose disassembly will facilitate the establishment, and which can be adjusted and linked by a simple mechanical system, for example by screwing. (Figure 5). According to an advantageous aspect of the invention, the internal cavity (10) of the receiving profile will have a slightly larger cross section than that of the headline (3), in order to facilitate positioning and to allow deformation thereof. when loading. According to an advantageous aspect of the invention, the core will consist of an elastomeric profile obtained by extrusion. According to another aspect of the invention, the core may be reconstituted a posteriori, by filling the cavity of the hem with a product more or less fluid, but hardening, resin type, or may be polymerized to form a foam of polymer or elastomer. This product, after a change of state, will take on a clean shape and keep it to the deformation, and will occupy the available space in the internal cavity (10) of the receiver profile, matching the shapes of the contact surfaces (8) of the receiver profile.

Avantageusement le durcissement dudit produit s'accompagnera d'un gonflement assurant le blocage par clavage en place de la ralingue dans le profilé receveur, et le parfait contact sur les surfaces d'appui. Dans le cas présent le fluide pourra consister en une résine auto-durcissable, ou tout autre produit injectable ou coulable aisément dans la cavité de l'ourlet .Advantageously, the hardening of said product will be accompanied by a swelling ensuring the locking by keying in place of the headline in the receiving profile, and the perfect contact on the bearing surfaces. In the present case the fluid may consist of a self-hardenable resin, or any other injectable product or easily cast in the cavity of the hem.
