DESCRIPTION OF PREFERRED EMBODIMENTS
(8) With reference to these drawings, FIG. 1 represents the protection of a boat hull of ogival form. The latter not being limiting. This fender is inflatable and deflatable. It comprises an extra flexible inner polyurethane 4 (FIG. 1) partially secured to the wall of the textile neck located at the appendage 5a (FIG. 3) of the device of the invention, the preformed knitted or woven outer part 5 (FIG. 1), covers the inflatable inner part 6 (FIG. 1), a stub 2 (FIG. 3) welded on the upper part of the appendage 3 (FIG. 3) equipped with a sealing stopper for inflating 11 (FIG. 3) and deflating 12 (FIG. 3). An end bit 1 (FIG. 1) which allows suspending the fender connected to the boat rail equipped with a flexible ring 7 (FIG. 1) allows the occasional inclination effect of the fender.
(9) Once the pressurization of the assembly FIG. 2 areas (A) and (B) is carried out by the user, the fender may be suspended safely to the boat.
(10) Area (A) of FIG. 2 is the area exposed to the vertical tractions of the device of the invention by way of non limiting example. The textile neck 5 (FIG. 5) will have dimensions of the order of 8 cm for the height and a diameter of 5 cm at the belt 10 (FIG. 3). This anti-deformation device integrated on the lower part of the appendage 3 (FIG. 3) allows maintaining its initial form during rises in pressure of the area B (FIG. 2).
(11) The pressure varies between 0.2 bar to 1.8 bar maximum, the suspension links 9 (FIG. 5) sewn on the textile neck are provided with steel D-shaped rings 8 (FIG. 5) allowing the passage of an end bit which itself is connected to the boat rail.
(12) The structure of the different pieces or parts constituting the invention represented by FIG. 3 defines the embodiment of the device of the invention.
(13) The polyurethane material is cut in one single piece folded on itself and welded at the ends in order to create a sealing inflatable casing shaping the body 3 (FIG. 1) and the appendage 3 (FIG. 1).
(14) Then a semi-stiff polyurethane belt 10 (FIG. 3) of a width of 1 cm is secured on the base of the appendage 3 (FIG. 3). This width is not limiting.
(15) On the upper part of the appendage, an orifice is created of a diameter of 3.2 cm to house therein a stub 2 (FIG. 3) equipped with an overlapping lip 16 (FIG. 4) of a width of 1 cm, integrated to a body threaded inside 13 (FIG. 3). The assembly is produced in polyurethane material in one single injection molding operation. It will be welded thanks to the overlapping lip 16 (FIG. 4), on the upper part of the appendage 3 (FIG. 3) of the polyurethane casing 4 (FIG. 3) thereby creating the sealing required for the assembly.
(16) Two stoppers are integrated to the assembly: one stopper with a check valve for the threaded body 13 (FIG. 3) for deflating 12 (FIG. 3), a second stopper provided for inflating 11 (FIG. 3) for the inner part of the stopper 12 (FIG. 3).
(17) The suspension links 9 (FIG. 5) are by way of example textile straps made at the ends of the stainless steel D-shaped rings. The suspension links are thus sewn on the neck of the textile casing 5 (FIG. 5) as well as an elastic 14 (FIG. 5) allowing bending the assembly of the textile neck. The appendage 3 (FIG. 3) will be secured to the inner wall of the textile neck, by the sizing method of the device of the invention.
(18) FIG. 4 represents the top view of the device of the invention: an inflating stopper 11 (FIG. 4), a second stopper 12 (FIG. 4) equipped with a check valve provided for rapid deflating; a polyurethane stub 2 (FIG. 4), integrated with a polyurethane lip seal provided to be welded; the suspension links 9 (FIG. 4), the polyurethane appendage 3 (FIG. 4), the textile casing 5 (FIG. 4).
(19) FIG. 5 represents the textile body 5 (FIG. 5) and the suspension links 9 (FIG. 5) of type straps woven and lined, with polyester with a very high resistance to traction of a thickness of 2 mm, of a width of 5 cm, and a length of 8 cm. These dimensions are not limiting. The suspension links 9 (FIG. 5) are sewn and produced with a machine by an operator. A twin needle stitching 17 (FIG. 5) produces a rectangle of 6 cm in height, 4 cm in width. A cross in twin needle stitching is carried out inside the rectangle so as to allow a distribution of the mechanical forces linked to the traction exerted by the pitching of the boat at the dock. A stainless steel D-shaped ring 8 (FIG. 5) distributes the load on the link.
(20) The device according to the invention is particularly intended for the safe suspension of the textile fender of a boat moored to the dock.
