Definitions
- the invention relates to a sub-assembly designed to make a gliding float on water. including a surf float.
- It also relates to a method of manufacturing such a subassembly and a float made from the subset in question.
- a surf float is made from a foam bar, especially polyurethane foam, which is formed in a mold.
- the foam bread is machined by planing and sanding on a small thickness to locally customize its then it is coated with a fiberglass shell impregnated with resin which forms an external reinforcement shell and gives the float its final shape.
- a decoration and a frosting give the float its final appearance.
- the foam bread is cut longitudinally into two parts which are then glued against a wooden slat which strengthens its structure and imposes a predetermined longitudinal camber.
- the disadvantage of such a construction technique is the weight of the float in the end.
- the foam is relatively dense, typically its density is 50kg / m3. And it is not possible a priori to decrease the density of the foam without harming the mechanical characteristics of the float.
- the central foam bar is generally made of polystyrene foam. This material has the defect of taking water. It happens that during its existence the float is hit against a reef or rock. If the outer shell is damaged, there is a risk to have water infiltration, water weighing down the float and being particularly difficult to clear out.
- This manufacturing technique allows for light boards. However, it it is not possible to customize the shape of the float. In this case the shape of the shell external depends exclusively on the shape of the mold.
- An object of the invention is to propose an improved sub-assembly, which makes it possible to carry out lighter surf floats while maintaining a customizable shape, or more bulky for an equal weight.
- a structural sub-assembly which according to the invention comprises a hollow inner shell, which is covered with a foam envelope suitable for machining.
- the float is characterized by the fact that it comprises the previously defined assembly covered with at least one layer of fibers impregnated with resin.
- Figure 1 is a top view of a surf float.
- Figure 2 is a side view of the float of Figure 1.
- FIG. 3 is a cross-sectional view of a float produced in accordance with the prior art.
- Figure 4 shows, in cross section, the structural sub-assembly according to a first embodiment of the invention.
- Figure 5 is a longitudinal sectional view of the float made from the sub-assembly in Figure 4.
- Figure 6 shows the same float in cross section.
- Figure 7, 8 and 9 are cross-sectional views illustrating three variant layouts of the invention.
- Figures 10 to 13 illustrate in cross section a fourth variant of embodiment of the invention in which the structural sub-assembly is produced in the form of two half-shells.
- a surf float is presented like an elongated board with a central part 2, a tapered front spatula and slightly raised 3, and a rear heel 4 slightly raised and with a reduced width.
- the float is made from a foam bar 5, typically polyurethane foam with a density of 50 kg / m3, which is covered with a sheet 6 of resin-coated fibers.
- foam bar 5 typically polyurethane foam with a density of 50 kg / m3
- sheet 6 of resin-coated fibers.
- the foam bread is made in mold, and it is available in different length, width, volume and variable camber. Once chosen by the manufacturer, the foam bread is put to the final shape desired by local planing on a small thickness, and only then, it receives its external coating. This coating increases the characteristics mechanical foam, and also protect the foam bread.
- Figures 4 and 5 show, respectively in cross section and in section longitudinal, a structural subset of the float according to the invention, that is to say the subset which is located under the outer lining of the final float.
- the sub-assembly is formed by an internal shell 7 which is coated with a foam envelope 8.
- the inner shell is hollow. It is a structural element for example made in fiberglass, carbon or other synthetic material impregnated with resin, resin polyester, epoxy or other.
- the internal shell is made with a thickness of between 0.15 and 0.2 millimeters, or between 0.10 and 0.25 millimeters, or even more depending on the intended use for the float and the type of resin used. In some cases and depending on the material used, the thickness can reach 1 to 2 millimeters.
- the internal shell can be produced using different techniques. For example she is formed around a central core made of polystyrene beads bonded with vinyl glue which is then dissolved in hot water. Other types of dissolvable chucks can be used or even an inflatable bladder.
- the shell is produced in several parts assembled together.
- the shell can be made from two half-shells (or half-shells) which fit into each other. Both parties are assembled by gluing or any other appropriate means. Other possibilities still exist.
- the shell 7 can also be constructed of materials other than fibers impregnated with resin, for example a thermoplastic, charged thermoplastic of fibers, of fibers projected with a polyester matrix, of stamped metal or any other material with high elastic modulus.
- resin for example a thermoplastic, charged thermoplastic of fibers, of fibers projected with a polyester matrix, of stamped metal or any other material with high elastic modulus.
- the shell is coated with an envelope 8.
- the envelope is made of foam, but different types of foams can be used.
- a PVC foam relatively dense, with a density of 50 to 70 kg / m3.
- polystyrene foam extruded or expanded from 30 to 50 kg / m3 or polyamide imide foams or any other waterproof foam.
- the thickness of the envelope is determined to allow subsequent machining of this sub-assembly on this small thickness while ultimately having a resistant sub-assembly and lightweight.
- the thickness is between 3 and 15 millimeters or even 20 millimeters.
- a greater thickness can be provided along the lateral edges and front / rear of the subassembly, and lower on the top and bottom. We can also provide different thicknesses on the top and bottom, on the front and rear.
- foam envelope glue sheets of foam that we curves to the shape of the shell by applying pressure, for example vacuum, leaving the inside of the shell at atmospheric pressure so as not to distort this shell.
- pressure for example vacuum
- a variant consists in placing the shell in the center of a mold in which the foam is injected, or else pour or spray this foam on the shell and leave it expand in the open air.
- the polymerization of the foam ensures its surface cohesion with the shell.
- a primer can be applied to the shell surface to improve the performance.
- the sub-assembly thus produced has the advantage of being light and resistant. Indeed, as the inner shell 7 is hollow, a significant weight saving is obtained by compared to a traditional mousse bread.
- the sub-assembly can be machined in the same way as a traditional foam bar, according to the wishes of the manufacturer, provided that the machining thickness remains less than the thickness of the foam.
- the invention provides for making several models of structural sub-assemblies with length, width, volume and camber variable.
- the structural sub-assembly with its layer of foam machined 8 ' is intended to be covered with a sheet 9 of glass fibers or other coated with resin, and to receive finishing operations in the same way as for a float traditional. This is shown in Figure 6.
- the inner shell is hollow, a user will have less problem in evacuating the water which will have seeped if necessary following a shock thanks in particular to the incorporation of a drain screw.
- This bladder can even be inflated with a gas lighter than air, for example helium, to further lighten the structure.
- Figure 7 relates to an alternative embodiment of the invention.
- the internal shell 10 is reinforced by a central partition 11.
- a central partition 11 is commonly used especially for long floats, to give them a determined camber and better longitudinal rigidity.
- the central partition 11 is for example made of foam or wood. She spans the length of the shell.
- the shell 10 is formed around this partition.
- the partition is bordered by two layers 13 and 14 of fibers impregnated with resin, which are continuously connected with the shell wall.
- the shell 10 is coated with a foam envelope 12.
- Figure 8 relates to another variant, where the upper wall of the shell 15 is supported by a foam plate 16 previously curved.
- the plate 16 is shaped by thermoforming or any other suitable technique.
- the lower wall of the shell is first produced, on which it is placed the plate 16 in place.
- the shaping of the shell is finished by covering the plate 16 with the sheet of fiber impregnated with resin, then the foam envelope 17 is formed.
- This plate 16 improves the resistance to penetration of the upper part of the sub-assembly, ie under the feet of the surfer.
- the plate 18 is in two parts 18a, 18b which is join at the level of a central partition 19 of the same nature as the partition 11.
- the shell 20 is closed above the plate 18 and the envelope 21 is formed around the shell 20.
- FIGS. 10 to 13 illustrate yet another alternative embodiment of the invention in which the structural sub-assembly is produced from two half-shells assemblies.
- the sub-assembly can thus be formed by an upper half-shell 22, which will form the bridge of the final float, and of a lower half-shell 24 which will form the hull.
- Each half-shell is formed of a foam plate 26, 28 which is first thermoformed in a mold and then covered, on an internal face 30, 32, with at least one layer of fabric impregnated with resin.
- the laminating operation of the internal face 30, 32 half-shells 22, 24 will be produced under vacuum while the foam plate previously thermoformed 26, 28 is still in the thermoforming mold, so that the layer of resin-coated fabric hardens on the thermoformed sheet while it is still pressed against the mold.
- the shape of the front half-shell is thus best guaranteed assembly.
- the rigid internal shell 7 which is formed by the layers of resin-coated fabrics arranged on the internal faces of the half-shells, and on the other hand the outer foam envelope suitable for being machined 8.
- the foams used are for example sheets of extruded polystyrene foam with a density of the order of 30 to 50 kg / m3.
- one of the half-shells for example the lower half-shell 24, is also laminated on its face 34 before the assembly of the two half-shells.
- the half-shell thus laminated on its two faces 32, 34 is then particularly rigid during assembly with the other half-shell, which allows to better control the precision of the assembly, and therefore the precision of the shape of the subset.
- the foam envelope covering the shell is not then more suitable for being machined over its entire surface.
- One of the faces is already laminate at the time of assembly, the geometry of this face can no longer be profoundly changed.
- the two half-shells are not symmetrical. Indeed, it can be seen that the lower half-shell 24 does not have no side edges.
- the plate When shaped, the plate is bent in the direction longitudinal (which is therefore not visible in the drawings) to follow the camber curve longitudinal (sometimes called "rocker” or "scoop” curve). She could also be curved in the transverse direction, for example to form a V-shaped or double hull concave, but in the example illustrated the lower half-shell has no curvature cross.
- the shaping of the plate can be done without thermoforming, simply by pressing the plate against the mold by vacuum when of stratification. After the resin has hardened, the stiffness of the resin-coated fabric is sufficient to maintain the plate in the desired shape of the half-shell.
- the upper half-shell 22 is thermoformed so as to be curved longitudinally, but also transversely to form curved side edges 36 down.
- the internal faces that is to say the lower face 30 of the half-shell upper 22 and upper face 32 of lower half-shell 24
- the lower face 34 of the lower half-shell 24 is also laminated, before the assembly of the two half-shells.
- the assembly of the two half-shells is obtained by sticking the lower edge of the side edges 36 of the upper half-shell 22 against the face upper 32 of the lower half-shell 24.
- the adhesive will be chosen so as not to be too difficult to machine, i.e. so as not to create a hard spot in the foam constituting the lateral edge of the sub-assembly.
- the stratification of the external surface in this case the lower surface 34 of the lower half-shell, can be total (as illustrated). It can also concern only one part of the surface, for example the central part to preserve perfect machinability of the side edge 38.
- the precise assembly of the two half-shells is facilitated by the high rigidity of the lower half-shell, and the sub-assembly remains suitable for being machined on its entire upper face and on its lateral edges, which leaves a large capacity for customization of the sub-assembly.
- the structural subset is covered with an outer layer of fibers impregnated with resin.
- the sub-assembly thus produced is a sub-assembly which, sense of the invention, comprises a hollow and rigid internal shell, and an envelope of foam capable of being machined which completely covers this internal shell.
- an envelope of foam capable of being machined which completely covers this internal shell.
- part of this envelope whose geometry we do not wish to modify, for example the upper face of the upper half-shell or the lower face of the lower half-shell, can be covered with a rigid outer layer.
- the invention could be applied to the construction of floats other than surf floats, for example for windsurfing floats, floats intended for swimming in the waves and overall, any nautical practice in which the float works mainly in the planar mode.
