Definitions
- the present invention relates to the field of sports equipment and in particular the field of inflatable boats. More particularly, the present invention relates to kayak type inflatable boats.
- Such boats are for example described in document US 9 452 809.
- Such boats are formed of a plurality of inflatable elements, for example so-called “dropstitch” materials, assembled together to obtain a boat having a general shape kayak.
- US 9 452 809 discloses an inflatable boat having a flat bottom which is not suitable in particular for a practice of kayaking on a sea with waves.
- the boat does not have either a hydrodynamic hull enabling efficient performance of the boat on the water.
- boat type boats in which only the floor is formed by a material called "dropstitch", and in which the sides of the boat are formed by cylindrical inflatable elements.
- Such boats are described in particular in documents FR 2 795 040 or FR 2 722 758.
- cylindrical inflatable elements arranged on the sides and forming the main buoyancy elements of the boat generally have a large size to give the boat rigidity and buoyancy sufficient.
- the present invention aims to solve the various technical problems mentioned above.
- the present invention aims to provide a kayak type boat having both a hydrodynamic shape similar to that of rigid kayaks, while keeping the buoyancy and rigidity necessary for an inflatable boat.
- an inflatable boat kayak type comprising a hull.
- the hull includes:
- a longitudinal bottom comprising a central longitudinal edge and two lateral longitudinal edges so as to have a V-shaped cross-section, the bottom comprising at least one inflatable envelope, and
- a stiffening upper structure comprising two longitudinal inflatable lateral envelopes and at least one transverse element mounted between the two lateral inflatable envelopes, each lateral inflatable envelope being mounted on one of the lateral longitudinal edges of the longitudinal bottom.
- the two lateral inflatable envelopes each comprise two superimposed walls, said walls each comprising a textile ply and being interconnected by a multitude of connecting threads distributed over the entire surface of said plies, forming a structure adapted to be inflated to a suitable pressure. to stiffen said structure.
- the structure of the inflatable boat according to the present invention thus comprises several independent volumes formed from a "dropstitch" type material.
- the different volumes make it possible, thanks to the high inflation pressure that can be used with the dropstitch material, to obtain elements having a high rigidity despite the inflatable nature of the boat.
- the upper stiffening structure forms a kind of cockpit for the user and reinforces the structure of the bottom of the boat where the weight of the user comes directly apply. Thanks to this reinforcement provided by the upper stiffening structure, it then becomes possible to design the bottom of the boat with a cross section V, that is to say with a hydrodynamic hull facilitating the movement of the boat to the surface of the water.
- the stiffening structure of the boat can limit bottom deformations, even with a V-shaped cross section, and keep the general shape of the hull even when the user is positioned in the middle of the boat and comes to apply its weight.
- the two lateral inflatable envelopes are not oriented, in cross section, as the sides of the longitudinal bottom on which they are mounted.
- the two side inflatable envelopes are mounted vertically on the longitudinal bottom.
- the bottom consists of at least one inflatable envelope, for example one or two inflatable envelopes.
- the bottom may be formed by a single inflatable dropstitch envelope which is sponsored so as to obtain the desired cross section, and more particularly the hull but also the bow of the boat.
- the dropstitch material is advantageously sponsored so as to obtain, once the two inflatable envelopes assembled together, the hull, and possibly the bow and stern, desired for the boat.
- the upper rigidification structure consists of two longitudinal inflatable lateral envelopes and one or two transverse elements mounted between the two lateral inflatable envelopes.
- the upper stiffening structure is disposed centrally relative to the bottom, that is to say at the level of the user's installation area. It is indeed in this area that will exert the greatest effort because of the weight applied in a localized way by the user on the hull of the boat.
- the upper stiffening structure thus comprises two longitudinal elements on either side of the user's installation area, in order to reduce buckling of the bottom when the user has taken a seat in the boat: the two inflatable envelopes longitudinal sides keep at a distance the two longitudinal ends of the bottom.
- the transverse element or elements of the upper stiffening structure make it possible to keep in place the two longitudinal side inflatable envelopes, and in particular to prevent them from coming closer to one another, always under the effect of the weight exerted by the user in the kayak.
- the upper structure of stiffening is designed to maintain a generally constant general shape, and is then placed above the bottom, at the user's home area, to maintain the general shape of the bottom, and therefore its hydrodynamics, despite the cross section in V of it.
- the inflatable envelope of the bottom comprises two superimposed walls, said walls each comprising a textile ply and being interconnected by a multitude of connecting son distributed over the entire surface of said plies forming a structure adapted to be inflated to a pressure capable of rigidifying said structure.
- the use of a bottom dropstitch material then provides rigid surfaces promoting the sliding of the water on their surface.
- each lateral inflatable envelope has a longitudinal length less than the length of the longitudinal bottom, and each lateral inflatable envelope is mounted on a portion of one of the longitudinal lateral edges of the longitudinal bottom.
- the longitudinal inflatable lateral envelopes are provided shorter than the bottom, in order to have a greater rigidity, and are arranged in the middle of the boat, where the user will settle and apply, by its weight, constraints on the hull, in particular buckling stresses leading the two longitudinal ends of the bottom to rise and get closer: the arrangement of the upper stiffening structure above the bottom thus allows to limit such buckling.
- the inflatable boat also comprises a stern and a bow, and the stern and / or the bow of the kayak is formed by a longitudinal end of the longitudinal bottom.
- the upper stiffening structure it becomes possible to provide a bottom extending to the two longitudinal ends of the boat, and thus can form the bow and stern of the boat.
- a hull is thus obtained in which the external surface on which the water slides when the boat is moving, is continuous and delimits, over the entire length of the hull, a single inflatable volume. This reduces the turbulence on the submerged surface of the hull, and thus the friction slowing the advance of the boat.
- the shell comprises two upper longitudinal edges formed by the two lateral inflatable envelopes of the upper stiffening structure, and the lateral longitudinal edges of the longitudinal bottom.
- the longitudinal longitudinal edges of the longitudinal bottom are each constituted, in the longitudinal direction, a central portion and two end portions, the central portion being lower than the two end portions, and each lateral inflatable envelope comprises an upper longitudinal edge.
- the two lateral inflatable envelopes of the upper stiffening structure are positioned in recesses or notches of the longitudinal bottom, to form, together, substantially planar upper longitudinal edges.
- each lateral inflatable envelope is mounted on the central portion of one of the lateral longitudinal edges of the longitudinal bottom, and each lateral inflatable envelope has a height corresponding to the difference in height between the central portion and the end portions of the longitudinal edge. the lateral edge on which it is mounted, so that the upper longitudinal edge of each lateral inflatable envelope forms, with the end portions of the lateral longitudinal edge on which it is mounted, an upper longitudinal edge of the shell, preferably substantially straight.
- the inflatable lateral envelopes each comprise an inner wall, an outer wall and a lateral edge interconnecting the inner and outer walls.
- the inner and outer walls may be the two superimposed walls each comprising a textile web and interconnected by a multitude of connecting son.
- the inner wall of the longitudinal bottom and lateral inflatable envelopes delimit or define, at least in part, the interior volume of the boat.
- the lateral envelopes are mounted, transversely to the longitudinal direction, in the extension of the bottom, so as to also delimit, at least in part, the interior volume of the boat.
- the inner walls of the shell are formed by the or the inner walls of the longitudinal bottom and the inner walls of the side inflatable envelopes.
- the outer and inner walls of the side inflatable envelopes are mounted, transversely to the longitudinal direction, in the extension of the inner and outer walls of the longitudinal bottom.
- the transverse element is mounted on the two lateral inflatable envelopes.
- the transverse member may be mounted on the top portions of the side inflatable envelopes, i.e. on or near the upper side edge of the side inflatable envelopes.
- the upper stiffening structure preferably comprises two transverse elements mounted at a distance from one another between the two lateral inflatable envelopes.
- the transverse element or elements are inflatable, for example each comprise two superimposed walls, said walls each comprising a textile ply and being interconnected by a multitude of connecting threads distributed over the entire surface of said plies, forming a structure adapted to be inflated to a pressure able to stiffen said structure.
- the two transverse elements of the upper stiffening structure may also be of dropstitch material, in particular to be inflatable while having sufficient rigidity to maintain the spacing of the two side inflatable envelopes.
- the upper stiffening structure may comprise two transverse elements, preferably intended to be positioned respectively in front of and behind the user when the latter is installed in the boat, in order to form a "peripheral enclosure" of stiffening surrounding completely the user.
- the inflatable boat also comprises a bridge, particularly flexible, mounted above the hull, especially at the front and rear of the boat.
- the bridge extends from one longitudinal end of the hull to the other, that is from the bow to the stern.
- the bridge is important for a kayak because it limits the entry of water into the boat. However, to be effective, it must be flat, or stretched in the case of a flexible bridge, to facilitate the evacuation of water and limit the formation of water pockets.
- a bridge is generally absent or partial on inflatable boats, because the inflatable structure of the hull, and its rigidity, do not allow it to stretch sufficiently.
- the bridge may comprise, preferably at the rear of the boat, an access opening to the interior of the boat.
- an opening provides access to the interior volume of the kayak, in particular for use as storage space for the personal effects of the user for example, or for security accessories.
- the boat may also comprise a sealing means, possibly sealed, comprising a sleeve defined by two open ends, one of the open ends being mounted on the bridge around the access opening.
- a sealing means possibly sealed, comprising a sleeve defined by two open ends, one of the open ends being mounted on the bridge around the access opening.
- the sleeve has a rectangular outline with large and small sides.
- Such a closure means ensures a minimum of tightness limiting the inflow of water into the boat.

- the closure means remains flexible, like the rest of the boat, which allows easier storage when the boat is deflated.
- the closure means possibly sealed, also comprises stiffening elements mounted on the short sides of the rectangular contour, preferably near the open end mounted on the bridge.
- the stiffening elements can even be designed to adhere to each other by contact, to further improve the sealing of the closure means.
- the stiffening elements extend between fold lines provided to facilitate the folding of the sleeve into a configuration wound.
- the stiffening means are designed to facilitate the folding of the sleeve, it can only be done along the lines defined by the stiffening elements (which are themselves difficult to bend).
- the inflatable boat also includes footrests.
- footrest means the complete system allowing the user to place his foot on a bearing surface, that is to say the system with the bearing surface and a fixing means to the user. boat and optionally a means for adjusting the position of the bearing surface.
- the footrests comprise two bearing surfaces slidably mounted along supports, the supports being fixed inside the boat and comprising flexible rods, preferably two parallel flexible rods.
- the rushes are for example rushes of headline.
- the rods thus form a support having both sufficient mechanical strength to allow to slide the bearing surfaces, and a certain flexibility to fold the boat when it is deflated.
- the footrests also comprise two adjustment straps each connected between a support surface and an element integral with the hull, for example a loop, disposed near the user positioned in the kayak.
- the adjustment straps allow the user to move the support surfaces along the rods, and hold them in position.
- the user unblocks the straps so as to allow free positioning of the support surfaces: it is then sufficient to press the bearing surfaces to push them along the rod.
- the boat also includes a coamley mounted on the bridge and allowing the user to attach a skirt.
- the coaming allows to mount a skirt on the deck, and thus to close the opening of the bridge allowing the entry of the user in the kayak, to further limit the water inflow into the boat.
- the coaming is formed of an elastomeric longitudinal band surrounding an opening of the bridge intended to receive the user.
- the coaming is classically rigid material, like the bridge.
- the coaming is chosen elastomeric material, in order to present both a mechanical strength for the attachment of the skirt, but also a certain flexibility for the storage of the boat in the deflated state .
- the coaming has a cross section comprising a bent lip forming a hook mounted on a base, the base being intended to be fixed on the deck of the kayak, and the lip being configured to retain the elastic of the skirt.
- the boat also comprises a removable seat and two wedges, the two wedges being mounted on the inner wall of the hull, preferably at the junction between the longitudinal bottom and the side inflatable envelopes, and the seat having a seat with recesses of complementary shape to that of the wedges and configured to cooperate with the wedges.
- the seat of the boat is provided removable, so as not to hinder the folding of the boat when it is deflated.
- the boat also has two wedges to position and maintain the seat in the hull during the practice of kayaking.
- the wedges which are advantageously positioned under the seat cushion, are arranged at the junction between the longitudinal bottom and the side inflatable envelopes. In this way, with a substantially horizontal base, it will remain under the seat, a space due to the V geometry of the longitudinal bottom which will on the one hand to possibly collect water that would be returned to the hull, without impregnating the sitting, and secondly a deformation of the seat under the weight of the user, for more comfort.
- the seat may comprise a backrest intended to bear against the transverse element of the upper stiffening structure.
- the presence of the transverse member, which is rigid, is used as support for the seat. This facilitates the design of the seat, including the connection between the seat and the seat.
- the boat also comprises at least one additional removable seat, and at least two additional spacers.

- the longitudinal bottom 4 comprises two longitudinal sides 20 joining, in the middle, along a central longitudinal edge 22 of the longitudinal bottom 4, and forming, on the outer sides, two lateral longitudinal edges. 24 of the longitudinal bottom 4.
- the two longitudinal sides 20 meet in the middle at an angle, so that the longitudinal bottom 4 has a V-shaped cross section.
- the angle of the longitudinal bottom 4 at the central longitudinal edge 22 may vary depending on whether the cross section considered is located near a longitudinal end of the longitudinal bottom 4 or close to the middle part of the longitudinal bottom 4.
- the cross section of the longitudinal bottom 4 may have a V shape with an acute angle, less than 90 °.
- the median cross section of the longitudinal bottom 4 may have a V shape with an obtuse angle, that is to say greater than 90 °, to give more space, especially in width, to accommodate the user.
- the two longitudinal sides 24 can meet to come respectively to form the bow at the front of the hull 2 and the stern at the rear of the hull 2.
- the two sides 22 of the longitudinal bottom 4 may each be formed of an inflatable envelope sponsored so as to obtain the desired shape of the longitudinal bottom 4 when the two sides are assembled together.
- the two sides 22 can be formed from a single inflatable envelope sponsored to achieve the desired shape: in this case, the longitudinal bottom 4 can be inflated or deflated with a single inflation valve.
- the inflatable envelope or envelopes used to form the longitudinal bottom 4 are preferably inflatable dropstitch envelopes, that is to say inflatable envelopes comprising two superimposed walls, said walls each comprising a textile web. and being interconnected by a plurality of connecting wires distributed over the entire surface of said plies forming a structure adapted to be inflated to a pressure capable of stiffening said structure.
- the use of the dropstitch material makes it possible in particular to use an inflation pressure of the high envelope, and thus to obtain a high rigidity of the envelope in the inflated state.
- such rigidity facilitates the flow of water along the submerged surface of the bottom, and therefore to limit the efforts to be provided by the user to advance the kayak.
- the dropstitch material makes it possible to obtain inflatable volumes with the desired shapes, and in particular substantially flat and non-cylindrical shapes, limiting the bulk of the kayak.
- the longitudinal bottom 4 may also comprise two wedges 26, for example of rigid foam, which will cooperate with corresponding recesses of the seat 14.
- the wedges 26 are preferably mounted on the inner wall of the longitudinal bottom
- the seat seat 14 is at a distance from the central longitudinal edge 22 and can then deform under the weight of the user to bring him more comfort .
- the wedges 26 can be mounted offset relative to each other, that is to say at a distance different from the median cross section of the longitudinal bottom 4: in this way, the seat 14 can be installed in the hull in the right direction.
- each lateral longitudinal edge 24 has a central portion 241 and end portions 242, the central portion 241 of each lateral longitudinal edge 24 being lower than the end portions 242, i.e. relative to the central longitudinal edge 22 smaller than the height of the end portions 242.
- FIG. 3 illustrates a side view of a lateral inflatable envelope 16, and more particularly the inner wall of a lateral inflatable envelope 16.
- the lateral inflatable envelope 16 is formed from a dropstitch material, that is, that is to say inflatable envelopes comprising two superimposed walls, said walls each comprising a textile ply and being interconnected by a multitude of connecting threads distributed over the entire surface of said plies, forming a structure adapted to be inflated to a pressure able to stiffen said structure.
- the inflatable lateral envelope 16 is intended to be mounted on a lateral longitudinal edge 24, and more particularly on the central portion 241, of the longitudinal bottom 4.
- the lateral inflatable envelope 16 may have a longitudinal length substantially equal to the length of the central portion 241 of the lateral longitudinal edge 24, and a height substantially equal to the difference in height between the central portion 241 and the parts d end 242 of the lateral longitudinal edge 24. More precisely, the lateral inflatable envelope 16 may have a height at its central portion which is greater than the height at the ends.
- the lateral inflatable envelope 16 can be positioned in the central portion 241 so that the lower longitudinal edge 27 of the lateral inflatable envelope 16 is fixed on the central portion 241 of the lateral longitudinal edge 24, and the upper longitudinal edge 28 of the lateral inflatable envelope 16 is positioned in the continuity of the end portions 242 of the lateral longitudinal edge 24, to form an upper longitudinal edge 30 of the substantially rectilinear shell 2 (see FIG. 4) , even substantially horizontal.
- Each inflatable lateral envelope 16 may also comprise a footrest 32 mounted on its inner wall.
- the footrest 32 may thus comprise a support 34 having two rods 36 that are flexible and parallel to each other.
- the rods 36 although flexible, have a sufficient rigidity to guide along the support 34 a bearing surface 38.
- the bearing surface 38 which is intended to serve as a support for the foot of the user during his practice, may have, for example, two grooves of shape corresponds to the two rods in order to slide along the rods.
- An adjustment strap 40 is mounted between the bearing surface 38 and a loop 42 secured to the inner wall of the lateral inflatable envelope 16: by exerting a force on the adjustment strap 40 at the level of the loop 42, it then becomes possible to bring the bearing surface 38 of the loop 42 while remaining on the seat 14 of the kayak 1. Moreover, once the bearing surface 38 correctly positioned, simply lock the adjustment strap 40 to prevent the bearing surface 38, under the effect of the constraints exerted by the user during his practice, does not move away from the passer 42.
- FIG. 4 illustrates the hull 2 of the kayak with the longitudinal bottom 4 and the two lateral inflatable envelopes 16: it can be seen that the addition and the positioning of the two lateral inflatable envelopes 16 make it possible to limit the buckling of the longitudinal bottom 4, in particular when a user comes to apply its weight on the middle part of the shell 2. More particularly, and as can be seen in FIG. 5, the two lateral inflatable envelopes 16 are not oriented, in cross section, like the bottom sides 20 longitudinal 4 on which they are mounted. Thus, the side inflatable envelopes 16 are inclined with respect to the sides 20, and preferably are oriented substantially vertically. This is particularly noticeable at the median cross section of the shell 2 at which the longitudinal bottom 4 has a V-shaped section with an obtuse angle.
- the lateral inflatable envelope 16 thanks to its height in its middle part, makes it possible to compensate for the height difference of the longitudinal bottom along the central part 241 of the lateral longitudinal edge 24.
- Such a geometry of the walls of the shell 2 allows to increase the rigidity and limit the buckling of the various components of the hull 2.

- the lateral inflatable envelopes 16 and the transverse elements 18 form a kind of cockpit inside which the user is intended to install, and reinforcing the rigidity of the longitudinal bottom 4.
- the transverse elements 18 are therefore preferably positioned in front of and behind the seat 14 of the user.
- the rear transverse element 18 can serve as support for the seat back 14.
- the bridge 8 can then be mounted on the shell 2 to close the upper surface thereof, with the exception of the opening provided for the entry of the user in the kayak 1.
- the bridge 8 includes a coam 12 for fixing a skirt (not shown).
- the coaming is formed of an elastomeric longitudinal band surrounding the user's entrance opening.
- the choice of an elastomeric material makes it possible to keep a sufficiently flexible element for folding the kayak 1 when it is deflated, while having sufficient mechanical strength to maintain the skirt of the user.
- the coaming 12 may comprise, in cross section, a curved lip 44 forming a hook. The shape of the lip allows to slide the elastic of the skirt so that it remains engaged in the lip 44.
- the curved lip 44 is mounted on a base 46 substantially flat, intended to be fixed on the surface upper deck 8.
- the deck 8 also includes the rear access opening 10 allowing the user to store inside the rear portion of the kayak 1, business.
- the kayak 1 comprises a closing means 48 illustrated in FIG. 8, in its closed configuration, and in FIG. an open configuration.

- One of the ends of the sleeve 50, the lower one is fixed on the bridge 8, around the access opening 10.
- the other end of the sleeve 50, the upper one also comprises stiffening strips 56 to facilitate the manipulation of the open end of the closure means 48.
- the sleeve 50 also comprises stiffening elements 58, preferably on the short sides 54 of the sleeve 50 which extend between fold lines 60 provided to facilitate the folding of the sleeve 50 in a rolled configuration. In this way, the user can easily wind the sleeve 50 only by folding it along the fold lines 60 provided for this purpose: thus improves the use and effectiveness of the closure means 48. Straps 62 can then be provided to maintain the closing means 48 in the closed state.
- the seat 14 can comprise a seat 64 and a backrest 68.
- the seat 64 is provided to have recesses on its underside, in order to cooperate with the wedges 26 of the shell 2. It can thus obtain a correct orientation of the seat 14 in the kayak 1, and a maintenance thereof in the longitudinal direction of the kayak.
- the backrest 68 is connected to the seat by a pivot connection, which can be a simple flexible connection.
- a pivot connection In order to keep the backrest 68 in position, and especially straight in the kayak 1, it can be placed in abutment against a transverse element 18, or even attached to the transverse element 18 for example with a velvet-hook type means.
- the design of the hull including its two-part structure with a longitudinal bottom and a stiffening upper structure, it becomes possible to manufacture a kayak with aerodynamics similar to that of rigid kayaks, while having a mechanical strength, and especially buckling resistance, high for an inflatable boat.
- the choice and design of the accessories fitted to the kayak makes it possible to maintain a flexible structure, without rigid parts that can damage the structure during folding.
