Description

[0001] The invention relates to a fastening system for attaching an object, in particular a mast, to a water sports board. According to a further aspect, the invention relates to a water sports device comprising a water sports board and a mast attached to the water sports board.

[0002] It is generally known to provide a fastening system on a water sports board, for example, to attach a mast to the board. Against this background, the requirement is that the mast should be as easy as possible for one person to attach, while at the same time, the fastening must be sufficiently robust to withstand significant forces caused by wind, water, and / or other environmental influences.

[0003] In this context, it is known to provide mounting rails on the water sports board to which an object, such as the mast, can be screwed. Such a mounting rail can be inserted into a receptacle of the water sports board and, for example, glued in place.

[0004] DE 10 2021 119 503 A1 describes a fastening system for attaching a hydrofoil to a water sports board, wherein a respective fastening rail is provided in two grooves arranged parallel to each other for fixing a connecting piece of the hydrofoil.

[0005] The object of the present invention is to provide an improved fastening system, in particular a particularly reliable and / or durable fastening system.

[0006] According to a first aspect of the invention, to achieve this object, a fastening system for fastening an object, in particular a mast, to a water sports board is proposed, comprising - at least one fastening rail which can be arranged on the water sports board, wherein the at least one fastening rail has two profile legs which form a receiving area between each other and whose distance in the direction of a rail opening between the two profile legs forms a taper, - at least one connecting element that can be arranged on the object, wherein the at least one connecting element can be introduced into the receiving area of ​​the at least one fastening rail, and wherein the at least one connecting element can be fixed in the region of the taper of the at least one fastening rail via a movable counter-element, and wherein the at least one fastening rail is at least partially reinforced at the taper via at least one stabilizing part to reduce abrasion of the profile legs, wherein the at least one stabilizing part is made of a different material than the two profile legs.

[0007] Within the scope of the invention, it was recognized that the taper between the two profile legs forms a highly stressed area of ​​the fastening system. To prevent unwanted wear there, at least one stabilizing part is provided in this highly stressed area as additional structural support.

[0008] The modified material compared to the two profile legs allows for the use of a particularly robust material. The stabilizing part is preferably arranged such that the connecting element and / or the movable counter element is pressed against the at least one stabilizing part during the fixing of the connecting element.

[0009] Preferably, the stabilizing element is inserted into the fastening rail during a manufacturing process of the fastening rail.

[0010] In the preferred embodiment, the object to be secured is a mast. Alternatively or additionally, the object to be secured can be a base, a sling, a mount for an external device, and / or the like.

[0011] The taper between the two profile legs of the fastening rail is preferably determined by a predetermined profile of the profile legs, such as a predetermined strip structure within the profile.

[0012] The movable counter-element can be designed to be movable outside the receiving area and / or within the receiving area. The movable counter-element can be part of a screw connection, part of a quick-release connection, part of a click connection, part of a clamp connection, and / or the like. In this sense, the counter-element is movable at least in one direction of movement, such as in an extension direction of the fastening rail within the receiving area.

[0013] Preferred embodiments of the fastening system according to the invention are described below.

[0014] In a particularly preferred embodiment, the at least one stabilizing part is formed from a metal. Such a metallic stabilizing part provides particularly robust protection against abrasion. Furthermore, such a stabilizing part can be manufactured particularly easily and reliably positioned within the fastening rail. Furthermore, such a metallic stabilizing part can be particularly robust against typical environmental influences of water sports equipment, such as water and / or sand. Preferably, the stabilizing part is formed from a metal sheet. Such a metal sheet can be processed particularly easily.

[0015] In an advantageous embodiment, a respective stabilizing part is provided on both profile legs of the at least one fastening rail. This can advantageously reduce the stress on both profile legs. Preferably, in this embodiment, the connecting element and / or the counter element only rubs against the respective stabilizing part within the fastening rail. Finally, the provision of multiple stabilizing parts allows the forces absorbed by the fastening system during use of the water sports board to be distributed among multiple stabilizing parts, thereby reducing the stress on a single stabilizing part. Accordingly, the fastening system according to this embodiment is particularly durable and robust.

[0016] In a further advantageous embodiment, the at least one stabilizing part has an L-shaped cross-section. Such an L-shape has two legs, so that one leg can be used to attach the stabilizing part and another leg can be used as abrasion protection for the fastening rail. Furthermore, such an L-shape allows for simple production of the stabilizing part, for example, by bending a metal sheet. The stabilizing part preferably has a width of less than 3 cm, in particular less than 2.5 cm, and particularly preferably less than 2.2 cm.

[0017] In a further advantageous embodiment, the at least one stabilizing part is designed as a stabilizing rail. This stabilizing rail preferably extends in the same direction as the at least one fastening rail. Such a stabilizing rail can advantageously reinforce a particularly large area of ​​the tapered section of the fastening rail and thus protect it from abrasion. The stabilizing rail preferably has substantially the same length as the fastening rail. In an advantageous variant of this embodiment, the stabilizing rail is formed from a metal sheet, in particular from a folded metal sheet. The stabilizing rail particularly preferably has an L-shaped cross-section.

[0018] Such a cross-sectional shape can further improve the stability of the stabilization splint.

[0019] In a further embodiment, the at least one stabilizing part is connected to the corresponding fastening rail in a form-fitting and / or force-fitting manner. By connecting the stabilizing part to the fastening rail in this way, a position of the stabilizing part is held particularly securely, even after the connecting element has been fixed several times. This makes it particularly reliable to prevent abrasion of the fastening rail. The form-fitting connection can be, for example, a snap-in connection, a click connection and / or the like. The force-fitting connection can be, for example, a clamp connection, a press connection and / or the like. Particularly preferably, a receptacle with a pressure profile, which is bent when the stabilizing part is inserted, is provided in the fastening rail.This ensures that the stabilizing part is held particularly securely in the predetermined position of the mounting rail.

[0020] In an advantageous embodiment of the fastening system according to the invention, the at least one stabilizing part is connected to the fastening rail on an underside thereof facing the water sports board in the arranged state. In this embodiment, accidental removal and / or removal of the stabilizing part from the fastening system is prevented. The stabilizing part according to this embodiment protects in particular against abrasion when tensile forces occur that pull on the connection provided by the fastening system. In order to fasten the stabilizing part to the underside of the fastening rail, the stabilizing part is fastened to the fastening rail before the fastening rail is permanently arranged on the water sports board, and only then is the fastening rail fastened to the water sports board.In an alternative or additional embodiment, the stabilizing part is connected to the upper side of the fastening rail, which faces away from the underside. Alternatively or additionally, the stabilizing part can be formed in the region of the tapered portion of the fastening rail, both on the underside and on the upper side.

[0021] In a particularly preferred embodiment, the connecting element can be fixed to the fastening rail via a screw connection. Preferably, in this embodiment, the counter-element is formed by a movable screw receptacle within the receiving volume of the fastening rail. The connecting element can be a screw that is inserted through the object to be connected and screwed into the counter-element within the fastening rail. This allows the object to be detachably connected to the water sports board. Preferably, several screw connections are provided for a reliable connection of the connecting element to the fastening rail.

[0022] In a preferred variant of the preceding embodiment, the movable counter-element, after being fixed to the fastening rail, is pressed onto the at least one stabilizing part within the receiving area. In this variant, the connecting element is screwed to the counter-element, so that after being fixed, the counter-element is pressed against the stabilizing part by the screw connection. In this variant, the counter-element is movable within the receiving area, i.e., preferably along an extension direction of the movement rail.

[0023] In a particularly advantageous embodiment, at least two connecting elements are to be fixed in a respective fastening rail. In this embodiment, the fastening system is designed to be particularly robust and stable. After the user has aligned and fixed the first connecting element, fixing the second connecting element can be particularly easy because no further realignment of the object to be connected to the water sports board is necessary. In an advantageous variant of this embodiment, at least two fastening rails are provided for the fastening system, with at least two connecting elements being fixed to each fastening rail. Such a large number of connections provided by corresponding connecting elements can enable a particularly high level of stability and robustness of the fastening system.

[0024] In a preferred embodiment, the fastening rail is formed at least partially from a plastic and / or carbon fibers. In this embodiment, the stabilizing part is particularly advantageous in order to prevent abrasion on the plastic and / or the carbon fibers. Such materials are particularly lightweight and dimensionally stable and are therefore suitable for use in a water sports device. In this embodiment, the selected materials therefore enable the provision of a particularly lightweight water sports device in which a reliable and robust connection between the object to be connected and the water sports board is nevertheless possible via the fastening system according to the invention. In this embodiment, the stabilizing part is particularly advantageously formed from a metal, such as a metal sheet.

[0025] According to a further aspect of the invention, to achieve the above-mentioned object, a water sports device is proposed, comprising a water sports board and a mast attached to the water sports board. The mast is connected to the water sports board via a fastening system according to at least one of the preceding embodiments.

[0026] The water sports device according to the second aspect of the invention comprises the fastening system according to the first aspect of the invention and therefore includes all of the aforementioned advantages. In particular, the water sports device according to the second aspect of the invention allows for a particularly reliable, robust, and durable connection between the mast and the water sports board via the fastening system, which is largely protected against abrasion in the connection area.

[0027] The water sports device is preferably a wakeboard, a surfboard, a kite surfboard, a wind wing foilboard, a SUP foilboard, a prone foilboard, and / or a windsurfboard. In principle, the described structure of the water sports device and the fastening system means that all water sports boards that need to be connected to an object can be connected via the fastening system according to the invention. In particular, the water sports board can be connected via the fastening system as an alternative or in addition to the mast, to a foot section, a loop, a holding area for an external device, and / or the like.

[0028] The invention will now be explained in more detail with reference to advantageous embodiments schematically illustrated in the figures. These show in detail: Fig. 1 a perspective view of an embodiment of a water sports device according to a further aspect of the invention with a first embodiment of a fastening system according to the invention; Fig. 2 a schematic sectional view of the first embodiment of the fastening system according to the invention; Fig. 3a,b a perspective view of a second embodiment of the fastening system according to the invention with an external appearance ( Fig. 3a) and a partial interior view ( Fig. 3b) the fastening system; and Fig. 4 a sectional view of the second embodiment of the fastening system according to the invention.

[0029] Fig. 1 shows a perspective view of an embodiment of a water sports device 100 according to a further aspect of the invention with a first embodiment of a fastening system 105 according to the invention.

[0030] The water sports device 100 with a water sports board 110 has a mast 120 attached to the water sports board 110. The mast 120 has at its lower end a connecting section 122 with a fastening plate 123 and with a connecting element 130, which in the illustrated embodiment is designed as a screw that is guided through the fastening plate 123. The fastening system is formed by two fastening rails 140, 140', into each of which two screws protrude as connecting elements 130, 130' to provide a releasable fixation of the respective connecting element 130, 130' in the corresponding fastening rail. Details of the fastening system 105 according to the invention can be seen in the following figures.

[0031] In Fig. 1 also shows a widened region 170 through which a counter element (not shown), which forms a screw connection with the connecting element 130, can be brought under and / or onto the respective fastening rail 130. The widened region 170 is formed at a rail end 172.

[0032] In principle, other objects can also be connected to the water sports board via the fastening system according to the invention, such as a foot part, a loop and / or the like.

[0033] The water sports device 100 may be a wakeboard, a surfboard, a kite surfboard, a wind wing foilboard, a SUP foilboard, a prone foil board and / or a windsurfing board.

[0034] Fig. 2 shows a schematic sectional view of the first embodiment of the fastening system 105 according to the invention. The illustration shows the fastening system 105 according to the invention in its inventive structure.

[0035] The fastening system 105 is designed to fasten an object, in particular the mast 120, to the water sports board 110. For this purpose, the fastening system 105 has at least one fastening rail 140 and at least one connecting element 130.

[0036] The fastening rail 140, which is arranged on the water sports board 110, has two profile legs 142, 144, between which a receiving area 145 is formed. The distance between the two profile legs 142, 144 has a taper 147 in the direction of a rail opening 146. The taper 147 is created by the profile of the two profile legs 142, 144 and is mirror-symmetrical with respect to a central axis of symmetry of the fastening rail 140 perpendicular to the direction of extension of the fastening rail 140. Such a symmetrical design of the fastening rail 140, which is also implemented in other embodiments not shown, supports a uniform loading of the taper 147 after the connecting element 130 has been fixed.

[0037] The connecting element 130, which is arranged on the mast 120, is in this case a screw that extends at least partially into the receiving area 145 to provide a screw connection with the counter element 150 in the area of ​​the taper 147. This screw connection fixes the connecting element 130 relative to the fastening rail 140 and therefore establishes a detachable connection between the mast 120 and the water sports board 110.

[0038] In the area of ​​the taper 147, at least one stabilizing part 160 is also provided on the fastening rail 140 to reduce abrasion of the profile legs 142, 144, which structurally reinforces the taper. For this purpose, the stabilizing part 160 is made of a different material than the two profile legs 142, 144. In particular, the stabilizing part 160 is made of a harder material, such as a material with a higher modulus of elasticity, than the two profile legs 142, 144. Thus, the two profile legs, preferably the entire fastening rail, are at least partially made of plastic and / or carbon fiber. In the illustrated embodiment, the stabilizing part 160 is made of a metal, preferably a metal sheet. Both profile legs 142, 144 have the same stabilizing part 160.In an embodiment not shown, the two profile legs have different stabilizing parts and / or are designed differently.

[0039] The two stabilizing parts 160 are embodied here as a stabilizing rail. This stabilizing rail extends essentially over the entire length of the fastening rail 130 in the direction of extension of the fastening rail 130. This allows for reliable fixation for various positions of the counter element 150 with reduced abrasion compared to areas without the stabilizing part 160.

[0040] In the illustrated embodiment, the stabilizing part 160 is inserted into a corresponding receptacle on both profile legs 142, 144, in which, due to the structure of the receptacle, a force-locking connection is created between the profile legs 142, 144 and the respective stabilizing part 160. Alternatively or additionally, a snap-in connection can also be provided as a form-locking connection of the stabilizing part.

[0041] In principle, the stabilizing part 160 can be connected to the corresponding fastening rail 140 in a form-fitting and / or force-fitting manner. The stabilizing part 160 can be arranged on the fastening rail 140 via a plug-in connection, a snap-in connection, a clamp connection, and the like. In an alternative or supplementary embodiment, an adhesive connection can be present between the stabilizing part and the fastening rail.

[0042] As in Fig. As shown in Figure 1, multiple mounting rails and / or multiple connecting elements can be provided for each mounting rail. This can provide a particularly reliable connection between the mast and the water sports board. Furthermore, a force acting on the mounting system can be transmitted to a plurality of connecting elements and thus to a plurality of stabilizing parts. This can minimize wear on the water sports board.

[0043] In the Fig. In the fastening system 105 shown in Figure 2, the counter element 150 is a movable threaded part arranged in the receiving area 145, so that by turning the connecting element 130, which is designed as a screw, the movable counter element 150 is fixed and pressed against the stabilizing part 160 on the fastening rail 140. Alternatively or additionally, the counter element can be movable by a tiltable component, such as in a clamp connection, in particular in a quick-release device. The counter element can also be located outside the receiving area, in which case the connecting element, for example via a connecting head, bears against the stabilizing part 160 and is thereby pressed against the tapered portion of the fastening rail according to the invention.

[0044] Fig. 3a,b show a perspective view of a second embodiment of the fastening system 305 according to the invention with an external appearance ( Fig. 3a) and a partial interior view ( Fig. 3b) of the fastening system 305.

[0045] The fastening system 305 is similar to the fastening system 105 of Fig. 2. However, it differs from this fastening system in the shape of the stabilizing part 360, which is shown in the partial internal view in Fig. 3b. Thus, the stabilizing part 360 is L-shaped. One leg of this L-shape is received in an edge of the fastening rail, and the other leg of the L-shape rests against the counter element 150, into which the screw is screwed as a connecting element 130 for fixing an object (not shown) to the fastening rail 340.

[0046] As in Fig. 3a, the stabilizing element 360 is not accessible from the outside for a user of the fastening system 305 and is therefore not exposed to any additional forces during storage or transport of the water sports board with the fastening rail 340.

[0047] In Fig. 3b also clearly shows that the fastening rail is preferably made of plastic, since with such a material the stabilizing element can be particularly easily and permanently brought into the position shown in the context of a printing and / or casting process.

[0048] The stabilizing element 360 is preferably formed from a bent metal sheet.

[0049] Finally, in the Fig. 3a and Fig. 3b also shows a widened region 370 in which the stabilizing element is not arranged or is narrower, so that the counter element 150 can be brought under the taper 147 of the fastening rail 340. In an alternative embodiment, the counter element is brought under the taper during a manufacturing process of the fastening rail and is then permanently held there by the taper of the two profile legs.

[0050] Fig. 4 shows a sectional view of the second embodiment of the fastening system 305 according to the invention.

[0051] The sectional view clearly shows that a lower end 380 is arranged below the fastening rail 340, which is formed from the two profile legs 342, 344 with the taper 147. The lower end 380 can be made of a different material than the profile legs 342, 344. The lower end 380 can be connected to the two profile legs 342, 344 by screwing, gluing, clamping, snap-in connection, and / or the like. In this exemplary embodiment, at least one stabilizing part 360 is connected to the fastening rail 340 on an underside thereof facing the water sports board in the arranged state. The stabilizing part 360 is thus concealed by the lower end 380. The lower end 380 in this exemplary embodiment can advantageously have a shape that is particularly advantageous for the connection to the surrounding water sports board.For example, there may be a particularly large contact surface on the water sports board in order to provide a particularly reliable and durable adhesive connection between the lower end and the water sports board.

[0052] From the above, it is clear that the stabilizing part according to the invention can also have a different shape, such as a zigzag shape, a wave shape, a round shape and / or the like, in order to stabilize the taper of the fastening rail and to protect it from abrasion.
