Abstract

The skin of an inflatable craft includes portions having an inner layer welded inside an outer layer forming a pocket for a thin solid core. At anchorage points on the hull structure, the same principal can be used, where a flat member forming the base of a threated rod used as an anchorage, is enclosed between an inner layer and an outer layer. The pocket between them can be filled with rubber. The rod can be used to carry a ring for mooring etc., and fitted with a lock nut and washer. A spacing washer can be included between the outer layer and the ring. Alternatively, the flat base which can be separate from the threaded rod can carry a rubber layer and be directly accessible from the inside of the single skin.

Structures gonflables, leur procédé de fixation et embarcations pneumatiques comportant de telles structures.Inflatable structures, their method of attachment and inflatable boats comprising such structures.

Le présent Certificat d'Addition se rattache au Brevet français NO 79/05825 dépose le ler Mars 1979 pour des "Structures gonflables, leur procédé de fixation et embarcations pneumatiques comportant de telles structures.This Certificate of Addition relates to French Patent NO 79/05825 filed March 1, 1979 for "Inflatable structures, their method of attachment and inflatable boats comprising such structures.

On rappelle que ces structures gonflables sont remarquables en ce qu'elles sont constituées d'une enveloppe souple comportant au moins une âme rigide plane ou en forme sur au moins une partie de sa surface.It will be recalled that these inflatable structures are remarkable in that they consist of a flexible envelope comprising at least one rigid plane or shaped core on at least part of its surface.

Selon une autre caractéristique intéressante de l'invention décrite et revendiquée dans le Brevet principal, ladite âme rigide est solidaire d'un moyen de fixation accessible à l'extérieur ou de l'extérieur des structures.According to another advantageous characteristic of the invention described and claimed in the main patent, said rigid core is integral with a fixing means accessible to the exterior or exterior of the structures.

D'autre part, à titre d'exemple de réalisation avantageux, il a été precise que ledit moyen de fixation est constitue par une ou plusieurs tiges filetees émergeant à l'extérieur de ladite structure et destinee(s) à la recep- tion d'ecrou(s) de blocage.On the other hand, as an advantageous example of embodiment, it has been specified that said fastening means is constituted by one or more threaded rods emerging outside said structure and intended for the reception of 'lock nut (s).

Le présent Certificat d'Addition a notamment pour objet d'apporter des ameliorations au procede d'incorporation des âmes rigides, plus particulièrement lorsque ces dernières sont destinees à constituer, par exemple, dans le domaine de la fabrication des embarcations pneumatiques, l'embase d'un dispositif de fixation d'une structure complémentaire (coque rigide) ou d'accessoires varies tels qu'anneaux d'amarrage et de remorquage, taquets, poignées de portage et d'amarrage, passants de filière en guirlande, supports d'aviron, supports de mains courantes interieures, supports de beaupré, tableau support de moteur, attaches diverses, etc...The purpose of this Certificate of Addition is in particular to bring improvements to the process of incorporating rigid webs, more particularly when the latter are intended to constitute, for example, in the field of the manufacture of inflatable boats, the base a device for fixing a complementary structure (rigid shell) or various accessories such as mooring and towing rings, cleats, carrying and mooring handles, chain loops in daisy chain, supports rowing, interior handrail supports, bowsprit supports, motor support board, various fasteners, etc ...

Selon une disposition caractéristique du present Certificat d'Addition, l'âme rigide constituant, de preférence, l'embase d'un dispositif de fixation, est revêtue, sur au moins sa face destinée à venir au contact de la surface intérieure du tissu enduit constituant l'enveloppe gonflable, d'une couche d'élastomère synthétique ou de caoutchouc, et ladite âme ou embase est ensuite soudée, par vulcanisation ou autre procéde de soudure à froid ou à chaud, sur ladite surface.According to a characteristic arrangement of this Certificate of Addition, the rigid core constituting, preferably, the base of a fixing device, is coated, on at least its face intended to come into contact with the interior surface of the coated fabric. constituting the inflatable envelope, of a layer of synthetic elastomer or rubber, and said core or base is then welded, by vulcanization or other cold or hot welding process, to said surface.

Selon une autre caracteristique, la matière d'enrobage de l'embase du dispositif de fixation est identique à la matière de l'enduction du tissu enduit dans lequel est exécutée la structure gonflable.According to another characteristic, the material for coating the base of the fixing device is identical to the material for coating the coated fabric in which the inflatable structure is executed.

Ce mode d'assemblage facilite la mise en place des embases des dispositifs de fixation, ameliore très sensiblement la permanence du parfait positionnement de ces dernières et procure une grande securite d'étanchéité autour des orifices de passage des tiges desdits dispositifs menagés dans l'enveloppe gonflable.This method of assembly facilitates the installation of the bases of the fastening devices, very significantly improves the permanence of the perfect positioning of the latter and provides great sealing security around the orifices for passage of the rods of said devices arranged in the envelope. inflatable.

Ces buts, caracteristiques et avantages, et d'autres encore, ressortiront mieux de la description qui suit et du dessin annexe dans lequel
La figure 1 est une vue en coupe axiale d'un exemple de réalisation d'une embase d'un dispositif de fixation, partiellement enrobee d'une matière destinée à permettre sa soudure sur la surface interne d'une enveloppe gonflable.These aims, characteristics and advantages, and others still, will emerge more clearly from the description which follows and from the appended drawing in which

La figure 4 est une vue en coupe axiale d'une variante de realisation de l'embase d'un dispositif de fixation.Figure 4 is an axial sectional view of an alternative embodiment of the base of a fixing device.

On se reporte audit dessin pour decrire des exemples d'exécution interessants, quoique nullement limitatifs, des structures gonflables perfectionnees selon le présent Certificat d'Addition.Reference is made to said drawing to describe examples of interesting, although in no way limitative, embodiments of inflatable structures perfected according to this Certificate of Addition.

Suivant une première disposition caractéristique, l'âme rigide ou chaque âme rigide des structures gonflables, constituée, de préférence, par l'embase d'un dispositif de fixation, est revêtue, sur au moins sa face destinée à venir au contact de-la surface interne du tissu enduit dans lequel est réalisée l'enveloppe desdites structures, d'une couche d'un elastomère de synthèse ou de caoutchouc (figure 1), et ladite âme ou embase est ensuite soude, par vulcanisation ou autre procede de soudure à froid ou à chaud, sur ladite surface (figures 2, 3 et 4).According to a first characteristic arrangement, the rigid core or each rigid core of the inflatable structures, preferably constituted by the base of a fixing device, is coated, on at least its face intended to come into contact with the internal surface of the coated fabric in which the envelope of said structures is made, of a layer of a synthetic elastomer or of rubber (FIG. 1), and said core or base is then welded, by vulcanization or other welding process. cold or hot, on said surface (Figures 2, 3 and 4).

L'enrobage de l'embase peut etre partiel ou total et execute par tout procédé de moulage ou d'adherisation convenable, notamment en fonction du materiau dans lequel est réalisée ladite embase (métal ou matière plastique rigide) et de la nature de la matiere d'enrobage.The coating of the base can be partial or total and executed by any suitable molding or adhesion process, in particular depending on the material in which said base is made (metal or rigid plastic) and the nature of the material. coating.

Selon un mode d'execution prefere, la matière d'enrobage servant au collage des âmes ou embases rigides est identique à la matière de l'enduction du tissu enduit dans lequel est executee l'enveloppe souple de la structure gonflable.According to a preferred embodiment, the coating material used for bonding the rigid cores or bases is identical to the material for coating the coated fabric in which the flexible envelope of the inflatable structure is executed.

Par exemple, si l'enveloppe souple de la structure gonflable est constituée à l'aide d'un tissu de polyamide 6/6 (Nylon) enduit de polychloroprene (Neoprene) ou de polyethylène chlorosulfonê (Hypalon), l'embase des dispositifs de fixation sera partiellement ou complètement revêtue d'une couche de polychloroprène ou de polyêthylène chlorosulfoné, respectivement, grâce a laquelle elle sera ensuite soudee sur la face interne de ladite enveloppe.For example, if the flexible envelope of the inflatable structure is made using a 6/6 polyamide (Nylon) fabric coated with polychloroprene (Neoprene) or chlorosulfonated polyethylene (Hypalon), the base of the fixing will be partially or completely coated with a layer of polychloroprene or chlorosulfonated polyethylene, respectively, thanks to which it will then be welded on the internal face of said envelope.

Cette soudure peut être effectuée à l'aide de tout procédé adéquat, suivant la nature de la matière d'enrobage et de l'enduction, a chaud ou a froid, par exemple, par vulcanisation, collage au moyen d'une colle appropriee, soudure par ultra-sons ou par courant haute fréquence, etc...This welding can be carried out using any suitable process, depending on the nature of the coating material and of the coating, hot or cold, for example, by vulcanization, bonding by means of an appropriate adhesive, welding by ultrasound or by high frequency current, etc ...

Suivant l'exemple d'exécution illustré aux figures 1 et 2, l'embase rigide 2p du dispositif de fixation est d'abord sertie dans un enrobage de caoutchouc naturel ou synthetique 13p qui recouvre sa face destinée à être appliquee contre la surface interne de l'enveloppe gonflable lp et est ensuite soudee à cette dernière au moyen dudit enrobage. Selon cet exemple, l'embase 2p est formee d'une seule pièce (en metal ou en matière plastique rigide) avec la tige filetee 4p du dispositif de fixation qui traverse un trou pratique dans le tissu de l'enveloppe 1p et sur laquelle est monté un anneau 8p maintenu par un ecrou 6p.Alternativement, la tige filetée 4p pourrait être rigidement fixee à 1 'embase 2p par soudure.According to the embodiment illustrated in FIGS. 1 and 2, the rigid base 2p of the fixing device is first crimped in a coating of natural or synthetic rubber 13p which covers its face intended to be applied against the internal surface of the inflatable envelope lp and is then welded to the latter by means of said coating. According to this example, the base 2p is formed in one piece (metal or rigid plastic) with the threaded rod 4p of the fixing device which passes through a practical hole in the fabric of the envelope 1p and on which is mounted a ring 8p held by a nut 6p. Alternatively, the threaded rod 4p could be rigidly fixed to one base 2p by welding.

Selon le mode de realisation represente à la figure 3, l'embase rigide 2q du dispositif de fixation est complètement noyee dans un enrobage 13q de caoutchouc naturel ou synthetique duquel emerge la tige filetée 49 dudit dispositif formee d'une seule piece avec ladite embase, et sur laquelle est egalement monte un anneau 8q maintenu par un écrou 6q, de la manière précédemment indiquée. L'embase 2q est soudee au tissu de l'enveloppe souple 1q au moyen dudit enrobage.According to the embodiment represented in FIG. 3, the rigid base 2q of the fastening device is completely embedded in a coating 13q of natural or synthetic rubber from which emerges the threaded rod 49 of said device formed in one piece with said base, and on which is also mounted a ring 8q held by a nut 6q, in the manner previously indicated. The base 2q is welded to the fabric of the flexible envelope 1q by means of said coating.

En outre, pour offrir une garantie absolue d'étanchéité, une flasque ou feuille d'étanchéité 3q de dimension plus importante recouvre l'embase 29 et est collee, par tout procédé adequat, à la fois sur l'enrobage 13q par sa portion centrale 3q', et sur la face interne du tissu enduit constituant l'enveloppe par sa portion débordante 3q". Cette flasque ou feuille d'etan- chiite est, de preference, executée dans un tissu enduit dont l'enduction est avantageusement realisee dans une matière identique à celle de l'enrobage de l'embase et à celle de l'enduction du tissu enduit de l'enveloppe souple.In addition, to offer an absolute guarantee of tightness, a flange or sealing sheet 3q of larger dimension covers the base 29 and is bonded, by any suitable process, both to the coating 13q by its central portion. 3q ', and on the internal face of the coated fabric constituting the envelope by its projecting portion 3q ". This flange or sealing sheet is preferably executed in a coated fabric whose coating is advantageously carried out in a material identical to that of the coating of the base and that of the coating of the fabric coated with the flexible envelope.

L'exemple de realisation illustre à la figure 4 diffère du mode d'exécution represente aux figures 1 et 2, principalement par le fait que le moyen de fixation est constitue par un ecrou borgne 14 solidaire de l'embase 2r et qui peut être avantageusement formé d'une seule pièce avec cette dernière.The embodiment illustrated in Figure 4 differs from the embodiment shown in Figures 1 and 2, mainly by the fact that the fixing means is constituted by a blind nut 14 integral with the base 2r and which can be advantageously formed in one piece with the latter.

Dans ce cas également, l'embase est partiellement ou complètement enrobée d'une couche de caoutchouc naturel ou synthEtique l3r comportant un orifice disposé en regard de ltentree de llecrou 14. In this case also, the base is partially or completely coated with a layer of natural or synthetic rubber 13r comprising an orifice disposed opposite the entry of the nut 14.

L'embase est soudée au tissu enduit 1r constituant l'enveloppe souple de la structure au moyen dudit enrobage.The base is welded to the coated fabric 1r constituting the flexible envelope of the structure by means of said coating.

Un trou est ménagé dans ladite enveloppe en correspondance de l'orifice permettant d'accèder à l'ecrou, pour autoriser le passage d'une vis 15 ou autre tige filetee servant, par exemple, à la fixation d'accessoires tels que taquet 16.A hole is made in said envelope in correspondence with the orifice allowing access to the nut, to allow the passage of a screw 15 or other threaded rod used, for example, for fixing accessories such as cleat 16 .

Comme indiquée dans le Brevet principal, chaque âme ou embase rigide peut être plane ou avoir la forme de la portion de l'enveloppe gonflable sur laquelle elle doit être fixée tandis que ses dimansions sont determinees par sa fonction. As indicated in the main patent, each rigid core or base can be flat or have the shape of the portion of the inflatable envelope on which it must be fixed while its dimensions are determined by its function.
