Abstract: Pneumatic valve (1) for an inflatable object such as an inflatable boat, arranged so as to be partially embedded in an aperture (22) in the flexible wall (21) of the inflatable object carrying it and comprising a valve body (2) containing a valve mechanism (1) and two collars (18, 20) like truncated cones surrounding the valve body (2) and gripping between them in a leak-proof manner the portion of the flexible wall (21) peripherally bordering the aperture (22); the two collars (18, 20) belong to two respective rings (17, 19) removably attached to the valve body (2), and sealing means (16) are provided between the lower ring (17) and the valve body (2); thanks to which the valve body (2) can present a transverse dimension approximately identical to that of said aperture (22) of the flexible wall (21) and fitting the valve (2) to or removing it from the flexible wall (21) can be carried out entirely from the exterior of the flexible wall (21).

Abstract: A mixed hull inflatable craft convertible into a closed box for its storage or transport is disclosed. The hull has a rigid body (1) with a top edge (5), a plane to which is fixed an inflatable buoyancy tube (7), a rigid closing panel corresponding in contour to the edge and an inverted U-shaped profile (15) interlocking the tube to the hull. The profile overlaps the top edge (5) of the body and has a first groove (16) open upwards and inside the body, retaining a ring (18) carried by a flexible skirt (19) connected to the tube; a second groove (20) open upwards and outside the body, receiving the edge of the panel closing the body (1) in the closed box conformation and supporting the flexible skirt (19) of the inflated tube located outside the body in the craft conformation; and an elastomer bead (21) located on the outside under the second groove (20) forming a sealed bearing surface for the inflated tube (7) in the craft conformation.

Abstract: Assembly of elements forming a mixed-hull inflatable boat which can be converted into a closed box for its storage/transport, including: an elongated rigid shell (1) with a profiled extremity (2) and the other extremity closed off by a transversal bulkhead (6); an inflatable tube (7) solidly attached to the shell (1) at least along its lateral edges; and a rigid panel (9) the peripheral contour of which follows that of the peripheral edge of the shell (1) and can be fixed in a removable fashion to it; thanks to which the assembly of elements can be configured for transport/storage with the tube (7) deflated and folded away in the shell (1) and the rigid panel (9) mounted on and locked to the shell to close it and form a closed box; and a navigation configuration with the panel (9) separated from the shell (1) and the inflatable body (7) inflated under pressure forming, together with the shell (1) forming a rigid hull, a mixed-hull boat.

Abstract: Device for attaching an oar (3) to the peripheral inflatable cushion (1) of an inflatable dinghy, characterized in that it comprises: a base (5) secured to the inflatable cushion (1) and having a retaining head (7), and a fastener (4) comprising, on the one hand, a mounting root shaped to complement the retaining head (7) so that it can be clipped removably onto this head and, on the other hand, above the said root, a ring (11) that can be deformed elastically in the radial direction and is shaped to grip tightly and elastically around the shaft (12) of an oar (3).

Abstract: The seat system comprises:two housings (7) including respective grooves (9) and secured to said base, the housings extending approximately parallel to each other;at least two legs (11) each including an elongate shank (15) terminated at each of its two ends by respective angled projections (15, 17), the bottom end ones of said projections (17) of the legs being inserted in the grooves (9) of respective ones of the housings (7) and being retained therein in such a manner that the shanks are upstanding while sloping relative to the vertical;a device (20) for locking the legs axially in their respective housings;a seat proper (10) suitable for standing on the angled projections at the top ends of the shanks (15); anda quick-fastening device for fastening the seat proper to the top angled projections of said shanks.
