Technical Field

The present invention relates to a kite board according to the patent claims.

Background

The performance characteristics of kite boards may vary widely depending on the shape of the board, weather conditions and water conditions. Therefore, most users have various kite boards with different performance characteristics to compensate for these effects. In addition to being expensive, this has the disadvantage of high requirements for storage space and transport space if various plates need to be brought to the waterside due to unknown weather conditions and water conditions.

Water boards, such as for example surfboards, sailboards or paddies with different configurations are known. In the following, some examples of adaptable water boards known from the prior art will be given.

US9650114 published by Maresh Joseph on 2017, 5 and 16 relates to a modular floating plate. The modular floating plate has a nose module, a tail module, and a middle module. The modules may be coupled together to a functional floating plate by an interface connection established between the middle module and the nose and tail modules. The tension members may compress the modules in longitudinal alignment and prevent separation of the modules of the assembled panels. Each of the modules operates independently.

WO06118949a1 published by Thomas Meyerhoffer on 9/11 2006 discloses a system of interchangeable components including various front and rear panels, adapters and interfaces that can be assembled in a variable and removable manner to form various customized water panels having various performance characteristics.

DE202014006073 published by Skywalk GmbH and Co KG on 9/25 2014 discloses a detachable plate having at least two parts which can be connected via a connecting device. The connecting device has a locking device for locking the connected parts and at least two bolts, wherein the bolts are firmly anchored in one part of the plate and can be inserted into corresponding holes in the other part of the plate.

CN203345156U published by hangzhou liangjin boats ltd in 2013, 12 and 18 relates to an assembly that combines surfboards, padsters and sailboats in one structure. The assembly comprises a base plate, an end buckle plate, a left buckle plate and a right buckle plate, wherein the end buckle plate is U-shaped. By fixedly assembling the different parts together, the assembly can be used as a surfboard, a paddle board or a sailboat.

Disclosure of Invention

It is an object of the present invention to provide a kite board that can be adapted to a wide range of different conditions. It is a further object of the invention to provide a panel which can be easily stored and transported in a space-saving manner.

The kite board according to the invention comprises a base, at least one forward extension and/or at least one rear extension. The base includes top and bottom surfaces and an outer edge surface. Here, the top surface is understood as the surface on which the rider stands during taxiing, and the bottom surface is understood as the surface that is placed in the direction of the water during taxiing. The outer edge face of the base extends in a circumferential direction along the outer contour of the top and bottom faces and comprises a first mechanical interface. The front and/or rear extensions further comprise a top surface and a bottom surface. Further, the forward and rearward extensions include inner edge surfaces. The inner edge face extends in the circumferential direction along the inner contour between the top face and the bottom face and is shaped such that the inner edge face at least partially corresponds to the outer contour of the base. The inner edge face of the front extension and/or the rear extension comprises a second mechanical interface foreseen to engage with a corresponding first mechanical interface of the base in the assembled position. The first and second interfaces engage each other to position the forward extension, and correspondingly the rearward extension, relative to the base. Alternatively or additionally, the first mechanical interface and the second mechanical interface may be arranged adjacent to the inner edge face and the outer edge face in the area of the top face.

By combining the base with different front and/or rear extensions, the width (in the lateral direction) and/or length (in the longitudinal direction) of the entire kite board may be adjusted. Thus, it is modularizedThe arrangement may be arranged with a fully functional base and one or more front and rear extensions. One base may be interconnected with one or more forward and aft extensions via first and second mechanical interfaces, covering the full range of different applications of the kite board. Thus, for each user, a respective kit may be provided that includes a base and at least two forward extensions and/or at least two rearward extensions, such that the user may replace the forward extensions and/or the rearward extensions to create different kite boards having different performance characteristics. Thus, in some applications, the base itself may be a fully functional kite board. In the case of the base as a kite board, the outer edge face of the base, respectively the transition region of the outer edge face and the bottom face of the base, develops into a so-called gliding edge which actively influences the gliding behaviour during gliding due to its interaction with the water surrounding the kite board. In this case, the edge serves as a flow separation edge. Since the sliding edges are subject to greater wear than, for example, the top side of the kite board, the sliding edges are preferably optimized in terms of fluid mechanics and in terms of structural performance. Thus, the edges of the kite board are often strengthened, and accordingly, the edges glide. This may be done, for example, by turning the fibres at the edges of the fibre-reinforced panel so that the ends of the fibre layers are not exposed at the outer edge face, and/or by using reinforcing filler material at the edges. Additionally or alternatively, the sliding edge may comprise a reinforcing element, preferably a reinforcing strip, which is placed on the outer edge face and thus reinforces the outer edge face. The reinforcing element can be made, for example, of ABS plastic. If the base can be used as a kite board, the base can represent a narrow kite board, which is known to be faster than a wide board. By combining the base with the forward and/or rearward extensions, kite boards with greater widths may be created, which results in more stable driving characteristics. Preferably, the width of the base is at W_BBetween 0.26 and 0.38m so that the base can be used without a front or rear extension. Advantageously, in various steps, by using different front extensions and/or rear extensions, then the width of the kite plate may be extendedUp to W_K0.5 m. The length of the base may vary together with the width or independently, depending on the application.

In addition to the width and length of the kite board, the shape of the entire contour of the kite board may be adapted. This can be done by using two extensions (a front extension and a rear extension) having different shapes or by using only one of the front extension or the rear extension. For example, the base may be a so-called "two-way" kite board as known from the prior art, which has a symmetrical and longitudinal form and can be used in both positive and negative longitudinal directions. However, in combination with the front and/or rear extensions, the overall shape of the (asymmetric) diving board (raceboard) may be produced. Depending on the application, the front extension and/or the rear extension may also include additional floats.

In order to interconnect the base with the front and/or rear extension, the first and second mechanical interfaces may comprise a recess and a tongue corresponding to the recess, the tongue being at least partially over the circumferential length of the outer and/or inner edge face. Alternatively or additionally, other mechanical interconnection means may be used, such as for example pins that can be inserted into corresponding holes. Preferably, the recess is arranged in an outer edge face of the base and the tongue is arranged in an inner edge face of the forward extension and/or the rearward extension. As mentioned above, this arrangement is advantageous in connection with the interaction of the water board if the outer edge surface of the base is a gliding edge, so that the base can be used as a kite board by itself (without the first and second extensions), since the tongues extending from the base cause unnecessary resistance and affect the performance of the entire board in a negative way.

Advantageously, in the assembled position, the front extension and/or the rear extension extend around the base and contact each other in the widest region of the base of the kite board, i.e. approximately midway with respect to the longitudinal direction of the kite board. The widest region is defined here as the region in which the base has the greatest width in the lateral direction (in the case of a kite board extending in the longitudinal direction). The front extension may additionally comprise a third mechanical interface on the side surface between the top and bottom surfaces foreseen to abut a corresponding fourth mechanical interface on the side surface of the rear extension between the top and bottom surfaces of said rear extension. As described above, the third mechanical interface and the fourth mechanical interface may further include a recess into which each other is engaged and a tongue corresponding to the recess.

For an advantageous fluidic design, the bottom surface of the front extension and/or the rear extension merges continuously into the bottom surface of the base in the assembled position. Thus, if the kite board is moved over the water surface, drag is minimized due to the smooth surface without a steep gradient in the bottom surface resulting from the interconnection of the base to the forward and/or rearward extensions.

For a stable interconnection, at least one first locking element may be present to lock (in a releasable manner) the front and/or rear extensions with respect to the base when in the assembled position. Here, the locking element preferably interconnects the base, the front extension and/or the rear extension in the longitudinal direction and the lateral direction of the kite board (accordingly, applying an interconnecting force), which gives a stronger structural interconnection. Alternatively or in addition, the at least one first locking element may also lock the front extension relative to the rear extension when in the assembled position. For an advantageous design in terms of fluid resistance, the at least one first locking element is here preferably located on the top surface of the base and/or the top surface of the front extension and/or the rear extension, on which no direct water-plate interaction occurs. Placing on the outer side of the kite board (extending in circumferential direction around the kite board between the top and bottom surface) is also disadvantageous, since the design and shape of the edges of the kite board is also known to affect the performance of the board.

In a preferred variant of the invention, the at least one first locking element comprises a tension element, at least two deflectors and a rope. Here, the cord is wound around at least two deflectors and the tension element tightens the string around the deflectors. The deflector deflects the cord in a manner that creates a deflection angle between the incoming cord and the outgoing portion of the cord at the deflector. Preferably, the deflector therefore features a guide groove, so that the string is prevented from slipping off. In one variant, the tension element may also deflect the string. The advantage of this arrangement is that it is easy to handle and different combinations are possible to assemble. Yet another advantage is a low profile arrangement that does not protrude significantly above the top surface of the plate.

If the parts that shall be interconnected are joined by means of the first mechanical interface and the second mechanical interface (pre-assembled position), the cords will be wound around the respective deflector and tensioned by the tension element. For easy storage of the cord, it is further advantageous if the tension member comprises a feed roller on which excess cord and/or cord over the entire cord length can be stored if no cord is used.

If two extensions (a front extension and a rear extension) are used, two first locking elements are preferably placed on the top surface of the base and/or the top surface of the front extension and/or the rear extension, wherein each locking element is located in the intersection area of the base, the front extension and the rear extension. In this case, at least three, but preferably four, deflectors can be used for each locking element. In the case of four deflectors, the rope forms a rectangle, with the deflectors at each corner of the rectangle deflecting the rope by 90 degrees. Thus, if one deflector is placed on the front extension, one deflector is placed on the rear extension, and two deflectors are placed on the base, the front and rear extensions are stabilized with respect to each other, while the front and rear extensions are stabilized with respect to the base and each other, respectively, against the base and each other — if the rope is re-tensioned by the tensioning members, strong and evenly balanced interconnection forces are generated in the lateral as well as in the longitudinal direction. The latter is here preferably placed on any part of the kite plate (base, front extension or rear extension) along the straight part of the (rectangular form of) string, so that only unidirectional forces are exerted on the tension members.

For a space-saving design, the base can also be divided into at least two parts. This further minimizes the required transport space. Thus, a first base portion and a second base portion may be provided, each comprising an interconnection face extending between a top face and a bottom face of the base, the interconnection faces being foreseen to abut each other. As described above, each interconnect face may include a mechanical interface. Furthermore, the first and second base portions may be secured in the same way as described above in the interconnected position by at least one first locking element and/or in the interconnected position by at least one second locking element interconnecting the first and second portions of the base in an independent manner. The second locking element may be, for example, a buckle.

In yet another variant of the invention, at least one fin is releasably attached to the base and/or the forward extension and/or the rearward extension. Thus, the base and/or the front extension and/or the rear extension may comprise at least one first insertion portion for attaching the fin on the bottom surface. Since the optimal placement of the fins depends on the size of each plate, the position of the fins is preferably adjustable. In addition, precise placement affects certain board properties such as steering ability and grip. Thus, advantageously, different fins having different sizes and shapes can be placed at various locations on the kite board and can be easily replaced and/or repositioned. The fins may be attached, for example, by means of threads or quick fasteners. Depending on the application, the base may comprise at least one second insert for releasably attaching the hydrofoil to the underside. Since the forces on the hydrofoil are higher with respect to the forces on the fins, the second insert part can be designed differently from the first insert part, correspondingly scaled. Furthermore, the front and/or rear extensions may comprise additional floats to compensate for the increased weight of the foils. Preferably, the first insert part and the second insert part are designed in such a way that no penetration occurs from the bottom surface to the top surface. Otherwise, when using kite boards, the pressure difference between the top and bottom surfaces due to the moving kite board may cause water to be pressed through the insert and form a water spray.

Detailed Description

Reference will now be made in detail to certain embodiments, examples of which are illustrated in the accompanying drawings, wherein some, but not all features are shown. Indeed, the embodiments disclosed herein may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Wherever possible, the same reference numbers will be used to refer to the same parts or portions.

Fig. 1 shows a first variant of a kite board 1 according to the invention in a perspective view from above and in an assembled position. The illustrated kite board 1 comprises a base 2, a forward extension 3 and a rear extension 4, such that the forward extension 3 and the rear extension extend around the base 2 and contact each other at the widest area (in lateral direction y) of the base 2. It can also be seen that in the variant shown, the base 2 can be divided into a first part 2a and a second part 2 b. In the perspective view of fig. 1, the top surface 5 of the base 2, and correspondingly the top surfaces 10 of the front extension 3 and the rear extension 4, are facing upwards (positive z-direction) and can therefore be seen in said view. In the assembled position, the outer side faces 7 extending in the circumferential direction along the outer contour 8 of the top and bottom faces 5, 8 are not directly visible, however, the edge of the top face 5 of the base 2 flush-mounted to the edge of the top faces 10 of the front and rear extensions 3, 5 can be detected. Furthermore, it can be seen that in the assembled position, the bottom face 11 of the front extension 3 and/or of the rear extension 4 advantageously merges continuously into the bottom face 6 of the base 2, so that, when in use, the fluid resistance can be reduced.

On the top side 5, 10, a first locking element 16 and a second locking element 24 can be seen, which first locking element 16 and second locking element 24 are illustrated in more detail in fig. 2. in the assembled position, the first locking element 16 locks the front extension 3 and/or the rear extension 4 relative to the base 2. preferably, in the assembled position, the at least one first locking element 16 also locks the front extension 3 relative to the rear extension 4. at the same time, the first part 2a and the second part 2b of the base 2 can be interconnected separately by at least one second locking element 24 placed on the top side 5 of the base 2. here, the first locking element 16 preferably comprises a tension element 21, at least two deflectors 22 and one cord 23. here, in the preassembled position (wherein the base and the front extension and/or the rear extension are at least by means of a first mechanical interface and a second mechanical interface), the cord 23 is first wound around the at least two deflectors 22, and then the tension element 21 deflects the cord 23 around said deflectors 22. in the applied position, the cord 23 is deflected around the first mechanical interface and the second mechanical interface, the cord 23 is guided between the deflected groove 22, thus, the deflected, the length of the cord 23 is varied between the deflected groove 22, the deflected groove 23, and the deflected groove 23 is a straight groove 23, a straight groove, a

In fig. 3, the sleeve 28 is illustrated as comprising a base 2 and at least two front extensions 3a, 3b and/or at least two rear extensions 4a, 4b (3 b not shown here). In the example shown, combining the base 2 with the rear extension 4a and the respective forward extension 3a results in a kite plate 1a that is wider and also longer than the kite plate 1b using the base, the forward extension 3b and the rear extension 4 b. However, other forward and rearward extension shapes may also be used in the sleeve 28. The illustrated kite panel kit 28 can be seen in a partially disassembled position providing a view of the outer edge face 7 and the inner edge face 12. An outer edge surface 7 of the base part 2 can be seen, which outer edge surface 7 extends in the circumferential direction along the outer contour 8 of the top surface 5 and the bottom surface 6. Said outer edge face 7 comprises a first mechanical interface 9, which first mechanical interface 9 is used for interconnecting the front and/or rear extensions via their second mechanical interfaces 13. Here, an inner edge surface 12 of the front and/or rear extension extends between the top surface 10 and the bottom surface 11, at least partially corresponds to the outer contour 8 of the base 2 and comprises said second mechanical interface 13. In the assembled position, the first and second mechanical interfaces 9, 13 engage each other to position the forward extension 3 and/or the rearward extension 4 relative to the base 2. In the illustrated case, the first and second mechanical interfaces 9, 13 comprise a recess 14 and a tongue 15 corresponding to the recess 14, wherein the recess 14 is arranged in the outer edge face 7 and the tongue 15 is arranged in the inner edge face 12. However, other mechanical interconnection means may be used, such as for example pins that can be partially inserted in the respective holes.

In fig. 5, a second variant of the kite board 1 according to the invention can be seen from a perspective view from below the bottom surfaces 6, 11. In this variant, the kite board 1 further comprises at least one first insertion portion 17, to which first insertion portion 17 at least one additional fin 18 may be attached. In the application shown, two (not used) first insertion portions 17a, 17b are located in the base portion 2. Furthermore, a total of four fins 18a, 18b are illustrated attached to the base 2 and the rear extension 4 via further first insertion portions 17, which first insertion portions 17 are obscured by the presence of the fins 18a, 18 b. However, the user may change the positions of the fins 18a and 18b using other insertion positions such as, for example, the positions of the first insertion portions 17a, 17b, due to personal preference or according to local weather conditions and water conditions. The number and location of the first insertion portions 17 may vary depending on the personal application.

In the variant of the kite board 1 according to fig. 1 to 5, the base 2 as well as the whole kite board 1 has the shape of a so-called "bi-directional" board, wherein the front extension 3 and the rear extension 4 are essentially "U" -shaped. However, other shapes of the base 2, the front extension 3 and the rear extension 4 are possible: thus, the fins 18a, 18b as shown in fig. 5 may also be applied to the kite board 1 in the form of e.g. a diving board.

Fig. 6 and 7 illustrate a third variant of a kite board 1 according to the invention. Fig. 6 shows a perspective view on the top side 5, 10 and fig. 7 shows a perspective view on the respective bottom side 6, 11. A third variant of the kite board 1 is an example where the front extension 3 and the rear extension 4 are different from each other such that the entire new shape of the kite board 1 is created based on the base 2. In this case, the base 2 has the shape of a "bidirectional" board, while, in the assembled position, the kite board 1 has the shape of a springboard with a greater extension in the longitudinal direction, and may be additionally characterized by a triangular cut 29 at the end of the rear extension. Additionally, the kite board 1 may be supplemented with hydrofoils 20. Thus, in this variant, the kite board 1 comprises at least one second insertion portion 19, on which second insertion portion 19 at least an additional hydrofoil 20 can be attached. Due to the higher forces acting on the hydrofoil 20, the size of the at least one second insert part 19 may be larger than the size of the first insert part 17. Additionally or alternatively, the base 2 may comprise a feed-through to insert a portion of the hydrofoil 20 and to fix the hydrofoil 20 on the top surface 5 (not shown here).

The words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
