Definitions
- the present invention relates to improvements to inflatable structures. It also applies to inflatable boats of the type comprising floats constituted by inflatable tubes.
- the inflatable boats being devoid of a drift plane, cannot go upwind as closely as possible using only one wing.
- the existing inflatable structures are devoid of proper means of assembly or fixing, so that they are generally subject to various supports (hulls of boats, chassis of helicopters or other flying machines, etc ... ) - or to various accessories (handles, motors, motor supports, etc.), by hot or cold bonding, vulcanization, welding by high frequency current or by infrared rays, or by similar processes.
- the inflatable structures are produced using natural or synthetic fiber fabrics coated with rubber, PVC or other synthetic material and the resistance to separation of these structures and the elements to which they are assembled is only determined by the peel strength of the coating layer.
- tearing off a patch of plaster even if it does not entail the complete separation of the inflatable structure and the element to which it is linked, reduces the seal of said structure and can cause the creation of a vanishing point.
- An objective pursued and achieved by the object of the invention is the production of inflatable structures capable of taking various forms depending on the uses envisaged.
- Another aim of the invention is to obtain inflatable structures provided with functional rigid surfaces, making it possible to obtain new results.
- an object of the invention is to remove the drawbacks arising from the use of special daggerboards, while providing said boats with a daggerboard plan allowing to use them for sailing.
- another object of the invention is to provide boats with skids intended to replace the inflatable structure by playing the role of lift elements in the event of failure thereof.
- Another advantage inherent to the claimed inflatable structures lies in the fact that they can be assembled, in a demountable manner, with various supports (rigid or semi-rigid boat hull, helicopter hooves, etc.) or to various accessories such as, considering, for example, one advantageous application to inflatable boats: blocks, handles, mooring and towing rings, chain loops, keel, table support-motor, bowsprit carrier, carriers oars, inner handrail supports, bow profile, various fasteners, etc.
- Another object of the invention is to allow an extremely resistant assembly of inflatable structures and their supports or accessories, this assembly being unable to cause no uprooting of
- a c *; 7i '' l * coating and, therefore, promote the appearance of a leak.
- the inflatable structures according to the invention comprise a rigid plane or shaped core on at least part of their surface.
- Rigid web or the rigid webs with which the inflatable structures are provided is or are integral with fixing means accessible to the exterior or exterior of said structures.
- 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, a layer of synthetic elastomeric x era or rubber, and said core or base is then welded by vulcanisation or other welding process in cold or hot, on said surface.

- FIG. 18 is a view in axial section of an alternative embodiment of the method of welding the bases of the fixing devices.
- Figure 19 is an axial sectional view of an alternative embodiment of the base of a fixing device.
- the inflatable structures have a rigid core on at least part of their surface.
- This core or rigid reinforcement can have any desired dimensions and can be made of any suitable material (rigid plastic, metal, etc.). It can be flat or have any shape or profile required by the destination of the inflatable structure in which it is incorporated.
- said rigid core or reinforcement can be made in a single piece or in several juxtaposed elements, so as to allow folding of the deflated structure, as explained below.
- the rigid, flat or shaped cores are incorporated into the inflatable structure, for example, before the latter is finished, according to any suitable method, in particular depending on the dimensions or the nature of said cores, some of these methods also entering into the scope of the present invention.
- the inflatable structure 1_ constitutes the floats of an inflatable boat and the external sides
- the of these inflatable floats or tubes, corresponding to the sides of the boat, are provided of a flat and rigid soul 2.
- the sides of the boat have a flat and rigid surface forming a drift plane, thanks to which the boats equipped with a wing can sail against the wind.
- Rigid cores or reinforcements can be formed in one piece, the length of which corresponds substantially to that of the floats in their straight portion, as shown in Figures 2 and 3.
- the cores or rigid reinforcements are preferably executed in several sections 2a_ - 2b_ - _2c - 2 ⁇ _ > ..., arranged in succession in the longitudinal direction of the tubes or floats, as illustrated in Figures 4 and 5, so as to allow the folding of said boats.
- the successive sections a - 2b_ - 2c_ - 2d _, ..., are sufficiently spaced that the folding can take place without abnormal tension at the folds.
- the rigid plates constituting the sections 2 ⁇ - 2b_ - £ - 2d, ... may have an increasing length, from one end to the other of the reinforced sidewall flanges and, for example, a forward barrier for inflatable structures folding by winding around the transom intended for fixing the engine.
- the lower part or bottom _le_ of the inflatable floats or tubes of the invention is provided with a rigid core 2e_ formed in one piece and whose length corresponds to that of said tubes in their rectilinear portion, or appreciably.
- This rigid core has a raised front end 2f so as to constitute a ski or skate.
- the inflatable boat is thus provided with two parallel pads incorporated into the floats and which, in the event of a puncture or burst, can slide on the water under the thrust of the engine of said boat which then evolves like a hydrofoil .
- the rigid webs and, in particular, the ski or skate 2e_ - _2f can be removable.
- a slot can be reserved at the rear of the float, at the base of the cone, for the introduction or the withdrawal of said ski, so as to allow folding of said float. ; ladi introduction taking place before full inflation of the tubes.
- the inflatable structures constituting the floats of inflatable boats can, at the same time, have a rigid core incorporated into their outer flank and a rigid core inserted into their bottom.
- the bottom and the side of the inflatable tubes 1g reinforced by the rigid cores _2 and 2h_, respectively, are assembled, at regular or non-regular intervals and at points distant from their articulation, by flexible internal tensioners Y ⁇ so that after inflating said tubes, said rigid and flat bottom and side thereof form, between them, a right angle, acute or obtuse.
- the bottom li 'and the flank li "reinforced with the inflatable bolster _li_ are rigidly secured, the single core 2A_ having, in this case, the shape of an angle.
- the rigid webs of the inflatable structures can be put in place according to different methods, depending on their dimensions, their function and the desired result.
- the rigid core 2k_ is placed in the suitable location, on the internal surface of the coated fabric lk 'or other impermeable material intended for producing the structure.
- inflatable Jj and it is covered with a flange or sealing sheet 3k_, for example made of a material identical to that of said coated fabric.
- This sealing flange is bonded, by its edge projecting 3k ′ to the internal face of the coated fabric, according to any suitable bonding method.
- the rigid webs 2_, 2a_ - b_ - lz_ - 2 ⁇ , 2e_ - 2f_, 2i_, 2j_, 2m, 2n_, are fixed according to this process, by means of a flange 3, 3a, 3e, 3i, 3j, 3, 3n_ , on the coated fabric in which the inflatable structures 1_, le_ are executed .
- lj_, lj_, IJ ⁇ , In_ according to the exemplary embodiments shown in Figures 1, 4, 7, 9, 10, 11, 13, 14 and 15, respectively.
- an advantage deriving from the invention, in particular in the application to the production of inflatable structures such as floats for pneumatic boats made up of sheets of coated fabric whose longitudinal edges are superimposed and glued by means of any suitable method is that it avoids the known phenomenon of weft leakage, which results from the fact that air enters through the inner edge of the structure, follows the weft threads and exits through the superimposed outer edge.
- the rigid core 2_ covers the inner longitudinal edge jL ⁇ _ of the rolled up sheet constituting the inflatable structure 1
- the sheet or sealing flange 3_ is placed overlapping on said rigid core and glued to the interior surface of said structure by its projecting portion. In this way, the air cannot penetrate through said covered inner edge V_ and escape outside.
- the rigid webs with which the inflatable structures are provided are rigidly secured to fixing means accessible outside or outside of said structures.
- these fixing means are constituted by one or more threaded rods emerging outside the inflatable structures.
- FIG. 10 illustrates an inflatable structure 1_3_ constituting, for example, one of the floats of an inflatable boat.
- the bottom of this structure comprises a rigid core _2j_ rigidly secured to threaded rods 4j_ regularly distributed along its length and emerging on the lower surface of said structure.
- Figure 11 shows the removable attachment of this structure on the upper edge 5__ of a rigid shell 5_ made, in a manner known per se, of metal, polyester, wood or any other suitable material.
- said upper edge has holes for the passage of rods 4j_; the assembly being carried out by means of nuts ' jj_ screwing onto the threaded ends of said rods.
- a joint for assembly and sealing _ 1 is preferably interposed between the surfaces in contact with the inflatable structure and the support (shell 5).
- FIG. 12 illustrates the attachment of a ring 8_ such as a mooring and towing ring, on an inflatable structure 3 _ such as a pneumatic boat float.
- the float comprises, at the front, a rigid core or base 2_k secured to an emerging threaded rod 4k_ tra- "*" - pouring an eye -that has the ring 8_; the assembly being carried out by means of a nut 6k_ screwing onto the threaded portion of said rod.
- An intermediate support washer 9_ is interposed between the contact surfaces of the inflatable structure! Lk_ and of the ring i3. 10 According to this method of attachment, it is possible to exert, without risk of tearing, significant tensile forces on the rings or handles subject to the inflatable structures. In fact, the resistance to the separation of the linked elements is maximum, since the force is not only distributed over a large area, but it is supported by the entire fabric 15 (weft + warp + coating) of the inflatable envelope.
- the rear end of the inflatable structures Irn (FIGS. 13 and 14) constituting the floats of the inflatable boats can also advantageously comprise a rigid core ⁇ 2m flat and of shape corresponding to the internal profile of the floats.
- FIG. 13 in the case of semi-rigid boats, that is to say a removable engine support table 10 (FIG. 14), for example in the case of inflatable boats without rigid hull.
- FIG. 15 illustrates the fixing of a bowsprit support jl_ at the front of an inflatable float ln_ whose prow is provided with a rigid core 2n_ secured to threaded rods j ⁇ passing through holes that the said support presents bowsprit; the assembly being obtained, as previously indicated, by means of nuts screwing onto the threaded ends of said rods.
- FIGS. 16 to 19 show a method of placing rigid webs which is particularly advantageous when the latter constitute the bases of fastening devices. This method of assembly facilitates the positioning of the bases of such 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 inflatable envelope.
- 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 surface.
- internal coated fabric in which is made the envelope of said structures, a layer of a synthetic elastomer or rubber ( Figure 16), and said core or base is then welded, by vulcanization or other welding process cold or hot, on said surface ( Figures 17, 18 and 19).
- the coating of the base can be partial or total and carried out by any suitable molding or adhesion process, in particular depending on the material from which said base is made (metal or rigid plastic material) and the nature of the coating material.
- the coating material used for bonding the rigid webs or bases is identical to the material for coating the coated fabric in which the flexible envelope of the inflatable structure is executed.
- the flexible envelope of the inflatable structure is formed using a fabric of polyamide 6/6 (Nylon) coated with polychlo roprene (N ⁇ oprene) or chlorosulfonated polyethylene (Hypalon), the base of the fixing will be partially or completely coated with a layer of polychloroprene or chlorosulfonated polyethylene, respec ⁇ tively, thanks to which it will then be welded to the internal face of said envelope.
- This welding can be carried out using any suitable method, depending on the nature of the coating material and of the coating, hot or cold, for example, by vulcanization, bonding by means of an appro ⁇ required, ultrasonic or high frequency current welding, etc.
- the rigid base 2g_ of the fixing device is first crimped in a coating of natural or synthetic rubber 13p which
- the base 2p is formed in one piece (made of metal or rigid plastic) with the threaded rod £ of the fixing device which passes through a hole made in the fabric of T J envelope jLp__ and on which is mounted a J3p_ ring held by a 6JD nut.
- the threaded rod could be rigidly fixed to the base 2 ⁇ by welding.
- the rigid base 2g_ of the fixing device is completely embedded in a coating 13q of natural or synthetic rubber from which emerges the threaded rod ' 4ç [_ of said device formed of a single part with said base, and on which is also mounted a ring 8c held by a nut 6cj_, in the manner previously indicated.
- the base 2 is welded to the fabric of the flexible envelope by means of said coating.
- a flange or sealing sheet 3c [of larger dimension covers the base 2 and is bonded, by any suitable process, both to the coating 13q by its portion. central 3g 1 , 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 made of a material identical to that of the coating of the base and that of the coating of the fabric coated with the flexible envelope.
- the embodiment illustrated in FIG. 19 differs from the embodiment shown in FIGS. 16 and 17, mainly by the fact that the fixing means consists of a blind nut 14. integral with the base 2r_ and which can be advantageously formed in one piece with the latter.
- the base is partially or completely coated with a layer of natural or synthetic rubber 13r comprising an orifice disposed opposite the inlet of T nut 1. It is welded to the coated fabric lr_ constituting the flexible envelope of the structure by means of said coating. 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_.
- the base 2 _ can be soli ⁇ dary of several blind nuts __ ⁇ A_ so as to allow assembly by means of a corresponding number of screws 15.
- 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.
- the invention also relates to the method of manufacturing and fixing inflatable structures consisting in incorporating into the latter, during their manufacture and in particular according to the assembly methods described in this presentation, one or more rigid cores or bases secured to the means link accessible outside or outside said structures, these means being, for example, constituted by one or more threaded rods intended to receive locking nuts or by one or more blind nuts rigidly integral with said souls or bases.
