EP4219288A1 - Foilwing - Google Patents

Abstract

A wing rig is disclosed in which removable handles are attached to a front tube or a center strut.

Description

The invention relates to a hand-supported wing rig for wind-driven sports, such as wing foiling, according to the preamble of patent claim 1.

Such a wing rig, also known as a foil wing or wingfoil, is described on the Internet, for example, under the name "Slingwing". In principle, it is a wing designed similar to a kite with a front tube forming a leading edge and a single strut, which are designed to be inflatable. On the central strut and on the front tube, holding loops are each formed, with which the user holds the inflatable wing rig during use, for example when foiling or ice surfing or skiing.

This inflatable wing rig is severely deformed during use, especially at the high speeds achieved when foiling, and the aerodynamics are thus impaired.

A further disadvantage of this known wing rig is that the straps are designed to be flexible, so that precise guidance of the wing rig, for example during tacking and jibing, when a change of hands is required, is made more difficult. In addition, these straps are firmly attached to the leading edge or strut, making them difficult to swap out or adjust.

Also known are solutions in which rigid handles are attached to the leading edge or the strut instead of the flexible straps. Such wing rigs, however, require considerable storage space when disassembled and deflated due to the protruding handles.

In the U.S. 4,563,969 a rigid wing rig is shown in which the leading edge and a boom is formed by a complex tubular construction which is a canvas (canopy) opens. The leading edge is curved in an arc shape as seen in a plan view. The tree is supported by a multitude of struts at the leading edge. These struts are designed in such a way that they give the leading edge a concave structure in a front view, ie seen in the direction of flow of the wing rig, according to which the end sections (tips) of the wing rig are issued upwards from a central apex of the leading edge.

A disadvantage of this solution is that due to the complex structure of the boom and the leading edge, the total weight of the wing rig is very high, so that it can only be used in water sports with the appropriate buoyancy devices. Another disadvantage is that the assembly and disassembly of the wing rig takes a long time due to the complex tubular structure. This hard tubular structure of the leading edge and the tree also poses a significant risk of injury to the user in a skid fall.

A similar rigid wing rig is in the WO 95/05973 A1 shown. With this solution, too, the leading edge and the tree are formed by a complex tube structure. The construction shows the same disadvantages as the wing rig according to the one discussed above U.S. 4,563,969 .

In the pamphlet DE 31 40 685 A1 describes a rigid wing rig, in which the leading edge (leading edge) is formed by two V-shaped masts, which are connected to one another via a central boom and support struts. This wing rig also has a considerable weight due to its tubular structure, which makes handling significantly more difficult, especially in water sports.

In the document U.S. 5,448,961 describes a flat wing rig with a closed frame structure - such a solution is also unusable for water sports due to the high weight, the time-consuming assembly/disassembly and the risk of injury.

The German Offenlegungsschrift DE 10 2015 117 708 A1 discloses a windsurfing rig provided with an inflatable mast and an inflatable transom is executed, which span a sail together. With this windsurfing rig, a mast base is integrated into the mast, which allows anchoring to a board. Such a concept is not usable as a hand-held wing rig.

In the also going back to the applicant DE 10 2019 101 656 A1 discloses a wing rig with an inflatable front tube and a rigid boom, which together span a sail, with the front tube being set in a V-shape in the direction of flow. The rigid tree is detachably attached to the front tube. The disadvantage of such a concept is that the weight of the boom, which extends from the front tube to the leading edge of the sail, is relatively large, so that the buoyancy of the wing rig in the middle area is relatively low in the water. The advantage of this solution is that the boom allows the wing rig to be held very variably, depending on the user's preferences. An additional attachment of handles is not required.

In the post-published pamphlet DE 10 2020 122 145 A1 the aforementioned concept is further developed in that such a tree is attached to an inflatable center strut of the wing rig.

In contrast, the invention is based on the object of creating a hand-supported wing rig for wind-powered sports that allows easy handling with little storage space.

This problem is solved by a wing rig with the features of claim 1.

Advantageous developments of the invention are the subject matter of the dependent claims.

The hand-supported wing rig, which is specially designed for riding foil boards, has an inflatable front tube from which an inflatable center strut extends.

This center strut is held by the user to guide the wing rig and, together with the front tube, spans a canopy (canopy), which forms the sail surface of the wing rig, so to speak. For optimal handling of the wing rig during maneuvers and while driving, at least one handle is provided according to the invention, which is attached to the front tube or to the center strut. According to the invention, this handle is designed to be removable, so that the wing rig takes up very little storage space when the handles are removed. Furthermore, for example, different handles can be applied, which are selected depending on the user's preferences.

For example, it is possible to attach either rigid or flexible handles. The concept makes it possible, for example, to provide a rigid handle in the middle of the front tube, while the handles in the area of the center strut are designed to be flexible.

In an exemplary embodiment of the invention, the at least one handle is approximately U-shaped, with the end sections being attached to the front tube or to the center strut by means of suitable adapters.

These adapters can be screw adapters, for example. In principle, however, other non-positively or positively acting adapters, for example with locking bolts or adapters designed for bracing, or even mixed forms, can also be used.

In a preferred embodiment of the invention, the adapter is designed with an adapter bracket that is attached to the wing rig and has, for example, a threaded bushing to which a support plate of the handle can be attached by means of a screw. The adapter console (patch) can be made of a flexible material, such as TPU.

The support of the handle is optimal if the adapter console is curved according to the diameter of the front tube or the center strut, so that the Support plate is supported flat on the outer skin of these elements. The adapter console can be designed as a flexible patch.

In an exemplary embodiment of the invention, the adapter can be designed in such a way that it can be clamped to an end section of the handle. Such a variant makes it possible to first insert the handle into the adapter without prestressing and then to brace it using suitable measures.

This bracing can be done, for example, by inflating the front tube and/or the center strut, with the handle first being placed on the adapter when the wing rig is not inflated, and then pumping creates a force/form fit and thus a bracing. Such an embodiment is characterized by a minimal outlay in terms of device technology, since, for example, the adapter can only be designed as a loop (more details will be explained below), into which the end section of the handle is inserted.

The adapter can advantageously stretch over a section of the front tube and/or the center strut (depending on which of these components the handle is attached to), so that the respective end section of the handle is in the area of the adapter on the one hand and the outer skin of the front tube or the center strut, on the other hand, can be used in a limited area, with the end section preferably being clamped against the adapter after the front tube or the center strut has been inflated, so that the end section of the handle is held in a non-positive and positive manner.

As indicated above, in a very simply designed embodiment, the adapter can be designed in the form of a loop from a band or belt-like material that is connected to the center strut or the front tube. Of course, instead of a band-like material, a molded part or the like can also be used.

The design of the handles is particularly flexible if they are designed in multiple parts with a web and at least one support arm. It is possible, for example, to use different handle concepts by exchanging the web and/or the support arm.

In this case, it is preferred if the aforementioned support plate is arranged on an end section of the respective support arm.

In one embodiment of the invention, it is provided that the support plate or a web of the handle that is inserted into or attached to the adapter has an end section that protrudes beyond the adapter, so that the user can easily check that the handle is attached in a predetermined manner positioned on the adapter.

The support of the handle is optimal if the support plate is curved according to the diameter of the front tube or the center strut, so that the support plate is supported flat on the outer skin of these elements.

In an exemplary embodiment of the invention, the handle can be braced on the one hand via a support arm and on the other hand via the web with the respective adapter. In an alternative solution, the handle has two support arms, each braced with an adapter.

The weight of the handle is particularly low if the web is tubular, with each support arm being designed with a connecting piece that dips into the tube or partially encompasses it, so that a reliable positional fixation is ensured. The support arms and the web can be connected in a non-positive and/or positive manner. The web can be straight or curved.

In an exemplary embodiment of the invention, two handles are arranged in an approximately V-shaped manner converging, with the converging area being fastened to the center strut and the respective end sections of the handles being fastened to the front tube are. These two handles arranged in a V-shape make it easier to perform the maneuvers described above or to hold the wing rig while foiling.

For clarification, it should be pointed out that the term “adapter” can be understood to mean any facility/device that is suitable for fixing a handle on the wing rig.

In figure 1 the use of a wing rig 1 according to the invention for driving a foil board 2 is shown. A surfer 4 holds the wing rig 1 with his hands only and adjusts it with respect to the wind depending on the desired direction of travel (upwind, downwind, downwind) or on the lift to be set, for example when jumping or adjusting the ride height.

The wing rig 1 has an inflatable front tube 6 with a leading edge 7 on the inflow side, which in the plan view (from above in the figures 1 and 2 ) is approximately arcuate, preferably approximately delta-, C- or U-shaped and extends with their tips 8, 10 up to a trailing edge 12 of a canopy 14 of the wing rig 1. As explained below, this canopy 14 is supported on the one hand by the front tube 6 and on the other hand by a tree or a center strut (see figure 2 ) stretched. The surfer 4 holds the wing rig 1 mainly on the tree/centre strut that is/is downwards (as viewed from figure 1 ) protrudes. The front tube 6 is preferably set in a V or U shape both in plan view and in a front view—seen in the direction of flow, with the V/U widening upwards in the front view, ie away from the surfer. How figure 1 can be removed, the trailing edge 12 and thus the entire canopy surface 14 is set in a V (or U) shape when viewed from the front.

By way of example, a handle that is arranged centrally in the area of the front tube 6 is identified by the reference number 16 . This handle 16 is gripped, for example, when the wing rig 1 is held while driving on a wave without propulsion in the wind. This handle 16 is also used when handling the wing rig 1 on land or when starting or ending a trip (water landing).

As explained below, further handles can be positioned on the wing rig 1. A special feature of the handle 16 is that it can be exchanged on the wing rig 1 , for example here on the front tube 6 or the center strut 18 .

In the representation according to figure 1 a safety leash 17 is also shown, which is fastened, for example, to the wrist of the surfer 4 and whose other end section acts on the front tube 6 .

figure 2 shows a three-dimensional view from below of a wing rig 1 according to FIG figure 1 . One recognizes in this representation the tree mentioned above, which in this Embodiment is designed as an inflatable center strut 18. This is attached to the front tube 6. The front tube 6 is designed similar to a front tube of a kite and is connected to the inflatable center strut 18 via a one-pump system (not shown in detail), so that both can be filled with air via a common valve. In the representation according to figure 13 the above-described handle 16 is shown, which bridges an apex 20 of the front tube 6 in the flow direction.

In the exemplary embodiment shown, the center strut 18 is curved upwards, with a strut section 22 on the inflow side connected to the front tube 6 being connected to the front tube 6 in the region of the apex 20 . Following this strut section 22 positioned approximately at right angles to the front tube 6 , the center strut 18 is arched upwards in a central section 24 towards the canopy 14 and then merges into a tapered end section 26 which extends to the trailing edge 12 . The canopy 14 is connected to the center strut 18 at least in sections, so that the profile described at the outset is established. The middle section 24 and the downstream end section 26 are connected to the canopy 14 . Between the front strut section 22 and the canopy 14 there is a space 27 which remains free or is filled with a cloth wall. Applicant reserves the right to make its own independent claim on the bulging inflatable center strut 28 .

In the illustrated embodiment, two V-shaped handles 28a, 28b are arranged in the area of the strut section 22, which are attached to the strut section 22 with their converging end sections. The end sections of the handles 28a, 28b that are remote therefrom are each on the underside (as viewed from figure 2 ) attached to the front tube 6.

Examples are then in figure 2 three further handles 30a, 30b, 30c according to the invention are shown, which are distributed along the center strut 18 from the connection of the two aforementioned handles 28a, 28b to the tapered end section 26 of the center strut 18. These handles are also arranged downwards, pointing towards the driver (view after figure 2 ).

Of course, such handles can also be attached to other positions of the wing rig 1. A special feature is that these handles are held on the center strut 18 of the wing rig 1 so that they can be exchanged in a simple manner. Replaceable is understood to mean a position fixation that can be loosened or fixed with little effort and with a simple tool, for example a screwdriver or wrench. It is not necessary to unpick seams or loosen rivets or an adhesive layer or the like.

In this way it is possible, for example, to provide different handles at different positions of the wing rig 1, with this positioning being able to be varied according to the preferences of the user. It only has to be ensured that on the wing rig side there are appropriate receptacles for fixing the handles 30 in position.

The handles 30 can be rigid or flexible. In the exemplary embodiment shown, the handles 30 are rounded, for example in a U-shape or V-shape.

figure 3 shows a variant of a handle 16 (of course, the other mentioned handles 28, 30 according to figure 3 executable), in which an approximately V-shaped structure with a straight web 32 is used, which is connected to the wing rig 1, for example the front tube 6 (only indicated in Fig figure 3 ) connected is.

Two preferably flexible adapter brackets 38, 40 are arranged on the wing rig side, on each of which a receptacle 42, 44 is formed, into which a threaded bushing, which will be explained below, is inserted. A support plate or a support element 46 , 48 of the support arms 34 , 36 can be positively inserted into this receptacle 42 , 44 and then fixed in position by means of a fastening screw 50 which is screwed into the threaded bushing of the adapter bracket 38 .

In the illustrated embodiment, this is sewn and/or glued to the outer skin of the front tube 6, so that the handle 16 is attached to the wing rig 1 in a very rigid manner when the front tube 6 is inflated. The adapter console 38, 40 can be flexible, for example as a TPU patch.

figure 4 16 shows an exploded view of the handle 16 according to FIG figure 3 . As explained, this handle 16 is attached to the front tube 6/leading edge 7, the two adapter brackets 38, 40 with the receptacles 42, 44 being attached to the front tube 6. According to the illustration in figure 4 these receptacles 42, 44 are each designed as rectangular pockets into which the above-described threaded bushings 52, 54 are inserted in the middle. The support plates 46, 48 of the support arms 34, 36 are designed according to the profile of the pocket-shaped receptacles 42, 44, so that they dip into them with a precise fit. As explained, the support arms 34, 36 are set at an angle in the exemplary embodiment shown, so that they converge towards the web 32. At the end sections pointing towards the web 32, the support arms 34, 36 are formed with connecting pieces 56, 58 which are aligned coaxially with the web 32 and at least partially dip into the tube profile of the web 32 or enclose the corresponding end sections. The position of the web 32 in relation to the connecting pieces 56, 58 can be fixed, for example, in a material-to-material, form-fitting and/or force-fitting manner.

The handle 16 shown can be made, for example, from fiber-reinforced plastic or light metal or another suitable material and is therefore designed to be comparatively rigid. Due to the interchangeability, this can be easily exchanged for a flexible handle.

In figure 5 the adapter bracket 40 (patch), the support arm 36 and part of the web 32 with the threaded bushing 54 are shown in an exploded view. It can be seen from this representation that in this exemplary embodiment the receptacles 42, 44 and the support arms 34, 36 are made of fiber-reinforced plastic, with the wall thicknesses being reduced in order to minimize the weight.

The threaded bushing 54 is inserted into a bushing receptacle 62 with a hexagon 60, so that the threaded bushing 54 is secured against rotation. The preferably flexible adapter bracket 40 rests with its bearing surface 64 on the outer skin of the front tube 6 or the center strut 18 and is—as explained—for example glued and/or sewn to it. The inclined support arm 36 has the support plate 48 described above, which can be inserted into the receptacle 44 of the adapter plate 40 with a precise fit. In the illustrated embodiment, the support plate 48 is formed with a central bore 66 through which the mounting screw 50 is threadedly engaged with the threaded bushing 54 . The connecting piece 58 dips into the inner diameter of the tubular web 32 and has a contact shoulder 68 against which the end face of the web 32 rests flush when assembled, so that a high-strength connection between the central web 32 and the two outer support arms 34, 36 is guaranteed.

In principle, however, the handles 16, 28, 30 can also be designed in one piece or with a different geometry.

As explained above, instead of the rigid handles 16, 28, 30, flexible handles or mixed types of handles can also be positioned.

In an exemplary embodiment of the invention, provision is made for a large number of adapter brackets 38, 40 to be provided along the front tube 6 and/or the center strut 18, so that the handles can be positioned individually.

figure 6 shows a further exemplary embodiment of a wing rig 1 according to the invention, in which the center strut 18 is reduced in diameter d in the area adjoining the front tube 6 compared to a section with the diameter D adjacent to the trailing edge 12, so that a recessed grip 70 is formed as a result of this stepping back , in the area of which two handles 30a, 30b according to the invention and a conventional holding loop 72 arranged between them are arranged. Accordingly, the handles 30a, 30b extend approximately as an extension of the area of the center strut 18, which is designed with the diameter D. A special feature of the handles 30a, 30b is that these with the center strut 18 and the front tube 6 are braced, this tension being brought about by pumping up the wing rig 1 . When the air is released, the handles can be attached to the front tube 6 or the center strut 18 without any tools and without any significant effort, so that the handles 30a, 30b can be fitted and removed in an extremely simple manner.

The handle 30a is connected to the in figure 6 left end section to area 74 with a larger diameter D on the one hand and approximately centrally within recessed grip 70 on the other hand. Specifically, in the illustrated embodiment, the two adapters 76, 78 are each formed by webbing loops 80, 82, which are sewn with their respective end sections to the outer skin of the center strut 18 and which bulge like a bridge, so that a reach-through area for a handle section is formed. At the in figure 6 Illustrated embodiment, the handle 30a has a support arm 34 at the right end portion, the basic structure of which is approximately that of the embodiment according to FIGS Figures 3 to 5 corresponds to and based on the Figures 9 and 10 is explained in more detail below.

As with the embodiments described above, the support arm 34 is connected to a tubular web 32 which extends to the region 74 having the adapter 76. As shown in FIG. The tubular end section 84 of the web 32 dips into the loop 80 and passes through it, with the end section 84 protruding from the loop 80 being fixed in position via a cap 85, into which the end section 84 dips, so that its movement in the illustration according to figure 6 is limited to the left. As will be explained in more detail below, the support arm 34 dips in the illustration according to FIG figure 6 from the right into the loop 82, so that the assembly of the handle 30a takes place simply by pushing it into the loop 80 or the loop 82 from the right.

The other handle 30b is attached in a corresponding manner via a support arm 36 and via a webbing loop 86 to the center strut 18 and to the in figure 6 right end section of the web 32 and another webbing loop 88 on the front tube 6 fixed. As in the case of the handle 30a, an axial displacement beyond the front tube 6 is prevented by a cap 90 which is attached to the loop 88. The difference in diameter between the front tube 6 and the center strut 18 in the connection area of the handle 30b is so large that there is sufficient clear width for gripping the web 32 . The handle 30b is attached by pushing it into the adapters 76, 78 in the direction of the front tube 6.

The conventional holding loop 72 is not detachably mounted between the two support arms 34, 36 and enables the wing rig 1 to be handled even when the handles 30a, 30b have been removed. This area is enlarged in the figure 7 shown. This depiction clearly shows the two webbing loops 82, 86, the end sections of which are each sewn to the outer skin of the center strut 18 and which bulge in an arc to form a receiving space 92 or 94 for part of the respective support arm 34, 36 to build.

The structure of the support arms 34, 36 is exemplified by the Figures 9 and 10 explained, which show an individual representation of the support arm 34 . Accordingly, they each have a support plate 48, which is curved according to the diameter D of the center strut 18 or the diameter of the front tube 6, so that a flat contact with these components is ensured. In the representation according to figure 9 the diameter D of the area 74 of the center strut 18 is shown as an example. A support arm 36 is attached to the side of the support plate 48, which in the exemplary embodiment shown is approximately U-shaped with a sloping base, so that the connecting piece 58 formed at the end section of the support arm 36 runs approximately parallel to the apex of the support plate 48. As in the exemplary embodiments described above, the connecting piece 58 is stepped back, so that a radial contact shoulder 68 is formed in the transition region to the section with a smaller cross section. The diameter e of the stepped-back area then corresponds to the inner diameter of the attached web 32, which rests with its end face on the contact shoulder 68 of the connecting piece 58 in the assembled state. In the illustrated embodiment, the support arm 36 is made of fiber-reinforced plastic. In principle, the support arm 36 can also be off be made from another material or using a generative process (3D printing).

How particularly good in figure 8 visible, the width b of the webbing loop 86 is slightly less than the width B (see figure 10 ) of the support plate 48 so that in the assembled state the support plate 48 (and of course also the other support plates) protrudes from the webbing loop 86 with a projection 96 . To fix the position, this overhang 96 can be provided with a step which bears against the associated webbing loop 86 in the pull-out direction and thus makes it even more difficult to inadvertently pull the support plate 48 out of the webbing loop 86 .

As with handle 30a, the end portion of web 32 remote from webbing loop 86 (see particularly figure 8 ) is inserted into the webbing loop 88 and secured in the axial direction via the cap 90.

figure 11 shows an embodiment in which the two handles 30a, 30b are attached only to the center strut 18. In this exemplary embodiment, this is not designed with a recessed grip 70 but in a conventional manner, so that there is no step in the transition area to the front tube 6 that a handle can stretch over.

In this embodiment, each of the handles 30a, 30b is provided with two support arms 34, 36 (in figure 11 only the support arms of the handle 30a are provided with reference numerals) between which the web 32 extends. Accordingly, the two structurally identical support arms 34, 36 are oriented in such a way that their connecting pieces 56, 58 (see Figures 9 and 10 ) assign to each other. The support plates 46, 48 then again engage in the respective webbing loops 80, 82 and 86, 88 in a non-positive and positive manner. Ie the webs of the handles 30a, 30b stretch over the respective webbing loops 80, 82 or 86, 88, so that assembly is only possible when the air has been released, with the handles 30a, 30b being practical in the inflatable state due to the force/form fit cannot be solved.

The conventional tether 72 is in turn mounted between the handles 30a, 30b. In the embodiment according to figure 11 (And also in the other embodiments), a handle 16 is releasably attached to the leading edge 7 of the front tube 6 in extension of the center strut 18, the structure of which is based on the figures 12 and 13 is explained.

Accordingly, this handle 16 in turn has two support arms 34, 36, which are essentially in accordance with the construction Figure 9 and 10 are trained. The support plates 46 , 48 in turn dip into webbing loops 98 , 100 of the adapters 76 , 78 which are fastened to the leading edge 7 of the front tube 6 . As in the embodiment described above, the two webbing loops 98, 100 are located between the support arms 34, 36, so that the handle 16 is reliably fixed in position.

In this exemplary embodiment, a web 32 made of an elastic material, for example a flexible hose, is placed on the two connecting pieces 56, 58 and is curved in accordance with the curvature of the leading edge 7 (see FIG figure 13 ). In the illustrated embodiment, the hose is press fitted onto the stepped back end portion of the connectors 56,58. Of course, the web 32 can also be additionally fixed in position by means of fixing elements, for example catches, screws, clamps or the like. Of course, this also applies to the other handles 28, 30 described.

In the exemplary embodiments described above, the center strut 18 is designed to be inflatable. As explained at the outset, instead of this inflatable center strut 18, a center strut designed as a tree or additionally designed with a tree can also be used. In this case, there is no need to attach handles to the center strut. However, it is definitely advantageous to provide the handles 16 and 28a, 28b described above in addition to the tree to simplify handling.

A wing rig is disclosed in which removable handles are attached to a front tube or a center strut.
