Description

The invention relates to a sailing rig according to the preamble of claim 1 and a sailing rig set.

Such a sailing rig can be used, for example, for a SUP, a windsurf board, a sailing boat or for any sport objects that move through wind power.

Previously known rigs usually have a mast made of metal or high-strength plastic, to which the luff of the sail is attached. At Windsurfriggs, the sail has a mast pocket into which the tapered mast is inserted.

With a windsurf rig, the sail is tensioned using a boom that is attached to the mast via a boom fitting and over which the clew of the sail can be tensioned using a tallje to trim the sail in the desired manner.

High-quality SUP boards are often also designed with mountings for a mast foot, so that the windsurfing frig described above can also be attached to a SUP board, for example to bring windsurfing closer to a beginner and thereby take advantage of the stability of a SUP board.

Rigging these aerodynamically optimized rigs, however, requires a relatively large amount of experience. Furthermore, due to the high-quality materials, these rigs are relatively expensive, so use with SUP boards is rather rare. A further disadvantage of such windsurfing rigs is that they are comparatively heavy and, in the event of a fall, lie relatively deep in the water, so that considerable forces have to be exerted in order to pull the rig out of the water and remain on the windsurfing board. Another disadvantage is that to store the mast, the boom and the sail considerable storage space is required, so that it is difficult to carry the rig.

From the DE 20 2013 008 701 U1 an inflatable surf sail is known in which the mast and a boom with two boom spars is inflatable. The basic structure thus corresponds to that of conventional solutions. The sail is then held on the boom end fitting and on the mast. To stiffen the respective convexly curved and joined together at their end sections boom booms are internally provided with an aluminum tube, which are connected by a rope. This rope is guided within a tube that extends through the sail between the boom spars.

Such a structure is very complex, and the sail profile is aerodynamically unfavorable due to the transverse tube. The additional stiffening elements also prevent compact folding.

In the DE-OS 28 31 766 discloses an inflatable sail in which one or more air chambers form a mast and a transverse strut arranged transversely thereto, which together span a sail. A receptacle for fastening a mast foot is formed on a foot-side end section of the mast.

A disadvantage of this solution is that the air chambers are designed with a comparatively thin cross-section and the rig is therefore not sufficiently rigid to be able to be used even with higher wind speeds.

In addition, in both of the above-described solutions, a receptacle for releasably attaching a mast base to the air chamber forming the mast is to be integrated. The connection of this receptacle to the air chamber can only be realized with great effort in terms of device and assembly technology.

In contrast, the object of the invention is to create a simply constructed sailing rig with sufficient stability and simple handling.

This object is achieved by a sailing rig with the features of claim 1. The object is also achieved by a set of such sailing rig according to claim 14.

According to the invention, the sailing rig has a mast strut and a cross strut on which a sail can be stretched. At least one of these struts is inflatable. This design makes it extremely easy to construct the sailing rig, since the strut or struts in question only need to be inflated. Both the structure and the handling are very simple thanks to the inflatable strut, which also ensures that the rig takes up a high swimming position and is therefore much easier to pull out of the water than conventional solutions.

Both the mast strut and the cross strut are inflatable. This variant has the great advantage that the sail is trimmed practically by inflating the struts, the sail tension, for example, being variably adjustable by the respective inflation pressure.

According to the mast base is preferably firmly connected to the mast strut so that a unit consisting of the actual sail, its struts and the mast base is formed and no additional component has to be attached. The connection of such a mast foot to an inflatable mast strut is much simpler than a variant in which the mast foot is detachably attached to the mast, as in conventional windsurfing rigs, since a complex mast foot mount must then be provided.

In one embodiment of the invention, the mast foot is attached via an adapter plate which is attached to an end face of the mast strut. A suitable connection of this end face area of the mast strut and the adapter plate ensures a reliable connection.

The mast foot can be designed in a conventional manner with a so-called power joint as a joint.

According to the invention, the sail or its sail panels (sail segments) is essentially connected to the cross strut towards the end of the cross strut. This connection can be made, for example, by sewing or via piping. According to the invention, therefore, only a cross strut is provided, which spans the sail together with the mast. This is a significant difference to conventional solutions, in which a boom with two boom spars is used across the mast, which enables the sail to be turned. According to the invention, this turning of the sail is made possible by the shape of the cross strut.

This cross strut can have an approximately round cross-section, wherein the diameter can change along the cross strut length. In principle, however, other cross-sectional profiles can also be used in order to optimize the sailing rig in terms of aerodynamics and / or strength.

In principle, it is also possible to assemble this cross strut from two half profiles, which are attached to the sail on both sides, so that a continuous sail surface can be used.

From an aerodynamic point of view, the sail can be optimally designed if the mast strut is designed with a sail top strut that is positioned at an angle to the mast axis and thus enables the sail top to be raised. This sail top strut can be attached to the mast strut or integrated into it.

The sail top strut is angled at an angle to the adjoining area of the mast strut.

The handling of the sailing rig can be further simplified if all struts can be filled using a so-called one-pump system. This means that all struts are pneumatically connected to one another via hoses, channels or the like and can be filled via a single valve.

The struts mentioned are preferably designed as tubes, the longitudinal and transverse profiles of which are selected with a view to the aerodynamics of the sail, so that it also withstands higher wind strengths. The profiling of the tubes enables the inflow profile to be optimally designed so that the respective board can glide in early.

In one exemplary embodiment of the invention, holding devices are arranged on both sides of the outer circumference of the cross strut, on which the user can hold the rig or else hang a trapezoid or the like.

These holding devices can be belt straps, profile bodies or the like, for example.

In one embodiment of the invention, the mast strut is seen from the foot and from the top towards the cross strut, so that the leading edge is curved or slightly V-shaped.

The construction of the sail rig is particularly simple if the sail is permanently attached to the struts in a suitable manner. Similar to a kite, this can be done by gluing, sewing to the struts. It is also conceivable to attach the sail using suitable detachable connecting elements, for example hook and loop fasteners, zippers or the like.

The following further developments can also be made the subject of dependent or independent claims.

According to a further development, the sailing rig is available in different sizes as a sailing rig set. In order to change the size of the rig, the height of the cross strut, that is to say its distance from the mast base, can be varied depending on the body size of the user. An area between the forehead and chest height has proven to be particularly suitable as the ideal position for a boom of a conventional rig. Accordingly, the invention Rigging set designed so that users with different body sizes can choose an ideal cross strut (boom) position for you.

The applicant reserves the right to set its own claim sets on the sailing rig set and / or the following aspects.

The mast strut is preferably approximately V-shaped to the cross strut.

In the connection area of the cross strut to the mast strut the latter is approximately cylindrical.

End sections of the cross strut and the mast strut can be extended beyond the sail.

The mast strut is approximately cylindrical in the connection area of the cross strut. Starting from this cylindrical area, the mast strut tapers towards the sail top and the mast base.

The cross strut can be designed with the maximum diameter in its central region, so that it tapers towards the mast strut and towards the intersection of the leech and the leech.

Catch-up handles are preferably provided on an upstream side of the mast strut. Due to the high swimming position of the sailing rig, the catching up is very easy, so that the use of a "Stutschot" (catch line) can be dispensed with, since the catching handles arranged on the front of the mast strut are sufficient to pull the sailing rig out of the water with minimal effort.

A sail top strut is placed at an angle to the mast strut. The angled area of the mast strut can be made in one piece with it or it can be made via a sail top strut connected to the mast strut.

In addition to the sail top strut and the cross strut, further slat-shaped struts can be provided.

The angle of attack of the sail top strut to the mast strut can vary depending on the size of the sail.

In order to form a sailing rig set (S, M, L, ...), the angle of the crossbar can also be varied in addition to the height position of the cross strut, on the one hand to provide an adjustment to the wind strength and on the other hand to provide an optimal sailing rig for every body size that this can also be used in training.

The applicant reserves the right to claim that the sail rig sizes of the sail rig set are determined in each case by the height position of the cross strut, the angle of attack of the sail top strut and the total length of the mast strut and the cross strut, sail rigs in graded sizes with a predetermined position of the cross strut or of a boom are not yet known.

The dimensions of the mast strut and the cross strut mentioned in the concrete description can also be made the subject of claims.

To prevent damage to the mast strut-side area of the mast strut, the latter, in particular in the seam area, is designed with reinforcements / protective elements.

Drainage openings, preferably in the sail, can be provided to support the drainage of water.

The sailing rig 1 has according to the Figures 1 and 2 a sail 2, which is spanned by means of a mast strut 4, a cross strut 6 and a sail top strut 8. All struts 4, 6, 8 are designed as tubes. Tubes of this type generally have an airtight bladder which is surrounded by a robust outer skin which is visible in the view. The tubes are filled via one or more valves 10. In the exemplary embodiment shown, a so-called one-pump system is implemented in which all struts are pneumatically connected to one another. In the exemplary embodiment shown, the pneumatic connection of the cross strut 6 to the mast strut 4 takes place, for example, via a hose 12, which is designed with a clamp 14, so that the two air volumes can be shut off from one another and the rig thus remains buoyant even in the event of a leak. In the illustrated embodiment, the sail top strut 8 is formed in one piece with the mast strut 4, a reinforced seam 16 being provided on the visible outer skin in the transition region of the two tube sections forming this structure. Such reinforced seams 16 are also provided in other highly stressed areas. The bladder is designed in a corresponding manner. In the area of connection of the cross strut 6 to the mast strut 4, a reinforcement 22 is also attached to the latter. The sail areas 2 above and below the cross strut 6 can be designed both flat and with a profile.

The sail 2 can be composed of several panels, which are preferably connected to the struts 4, 6, 8 by sewing or gluing. The connection plane preferably extends approximately along a central plane of the struts 4, 6, 8. This is based on the detailed section according to Figure 1a explained. Visible in this sectional illustration is the approximately round cross section of the cross strut 6, in which part of the above-mentioned bladders 30 is accommodated, which can be filled via the valve 10. According to Figure 1a extends the sail area of the in Figure 1a top and bottom sail panels 2a, 2b approximately in the dash-dotted median plane 32 of the cross strut 6. In other words, the two sail panels 2a, 2b are attached approximately centrally to the cross strut 6. This attachment is preferably carried out by gluing or sewing, whereby according to the embodiment Figure 1a Keder-shaped reinforcements 34 are provided, which enable an optimal connection between the sail 2 and the cross strut 6. The connection of the sail 2 to the mast strut 4 and the sail top strut 8 takes place in a corresponding manner.

In principle, it is also possible to assemble the cross strut 6 from two half profiles which are attached to the sail 2 on both sides. Of course, cross-sections deviating from the round cross-sectional shape can also be realized. The profile course is chosen so that the desired sail profile can be given to the sail when in use, which sail profile naturally also depends on the filling pressure of the struts. Furthermore, the profile of the cross strut is designed with regard to the optimal rigging of the rig.

In principle, it is also possible to hold the sail on the cross strut only in sections or in a sliding manner, so that the sail profile can be adjusted in the longitudinal direction of the cross strut by means of suitable trimming devices.

A receptacle for an indicated mast foot 18 is provided on a foot-side end section of the mast strut 4. This is attached to the mount and thus remains on the sailing rig.

The rig 2 is stabilized by the filling pressure, which can be in the range from 0.5 to 2 bar, the filling pressure - as mentioned - also determining the sail trim, among other things. In principle, additional devices for trimming the sail can also be provided. (E.g. battens like on a modern windsurf sail)

In the illustrated embodiment, the mast strut 4 is slightly V-shaped towards the cross strut 6 - this achieves the optimal bending line of a mast of a windsurfing rig.

The cross section of the struts 4, 6, 8 is also optimized in aerodynamic terms and in terms of strength. In the illustrated embodiment increases according to the Figures 1 and 2 the diameter D of the mast strut 4 towards the cross strut 6, the mast strut 4 being cylindrical in the connection region of the cross strut 6. This area is in Figure 1 provided with the reference number 36. The foot-side diameter and the sail-top side diameter of the mast strut 4 and the sail-top strut 8 are in this case significantly smaller than the maximum cross section in the region of the connection of the cross strut 6. This has its maximum diameter d approximately in the central area and tapers towards the leech of the sail 2 or for connection to the mast strut 4.

A holding device 20 is provided on both sides for holding the sail 2 approximately parallel to the longitudinal axis of the cross strut. This holding device 20 can according to Figure 3 For example, have a stable webbing 26 on which a plurality of holding loops 24a, 24b, 24c are held. These straps 24 can be made of webbing or the like or relatively rigid such as a harness. The reinforcement can be carried out in such a way that the holding loops 24 can be displaced. Of course, such a holding device 20 is formed on both sides of the cross strut 6 as in a surfrigg. Alternatively, the holding device 20 can also be formed by a profile body or the like, which is attached to the stable outer skin of the cross strut 6. This holding device 20 makes it possible to hold the sailing rig 1 or to hang in a trapeze. The cross-sectional profile of the tubes is according to the volume model Figure 2 good to see. As explained, taper the cross strut 4, the sail top strut 8 and the cross strut 6 towards their end sections, so that a statically stable structure with optimal aerodynamics is created.

As mentioned at the beginning, the sailing rig 1 is in no way limited to use with SUP or windsurf boards but can also be used in general in sailing, canoes, sand sailors, landboards etc.

By deflating the air through the central valve 10 or a vent valve 56 (see Figure 6 ) the air can be released from the holding structure, so that the sail rig with attached sail can be stowed in a minimal space. This makes it possible, for example, to carry the sailing rig 1 with a SUP, for example, and to inflate it when necessary.

At the end portions of the mast strut 4 and the cross strut 6 reinforcements 28 are provided to protect against damage.

A conventional kite or SUP pump can be used to inflate.

Based on Figures 4 to 10 a variant of the sailing rig described above is explained.

At the in Figure 4 In the variant shown, the leech 38 and the lower leek 40 end at a distance from the respective end section of the mast strut 4 and the cross strut 6. In other words, an end section 42 of the cross strut and a mast top 44 of the mast strut 4 are extended beyond the respective leech and protect the sail against damage when sanding on the surface.

According to the representation Figure 4 one also clearly sees the mast foot 18 integrated into the sailing rig 1, which is articulated and thus enables the sailing rig 1 to be angled with respect to the board surface or the like. The basic structure of this mast base 18 corresponds to that of a conventional mast base, with one difference, however, that in Surfriggs and the like that Mast foot 18 mounted on the board side and then inserted into the mast while it is integrated into the sailing rig 1 according to the invention.

To make it easier to catch up the sail 2 from the water are at the in Figure 5 shown flow surface of the mast strut 4 catch handles 46, 48 provided. The one in the Figures 4 and 5 Handle 46 located at the top is provided approximately as an extension of the cross strut 6. The catch-up handle 48 underneath is attached in the area between the mast base 18 and the catch-up handle 46 located above. As shown in particular in Figure 5 As a result, the mobile phones are not attached centrally to the seam 50 of the mast strut 4, but rather at an angle to it, with one handle end section to the left of the seam and the other end section to the right of the seam 52 - the mobile phones 46, 48 thus cross the seam, so to speak 52, which in turn is protected against wear by means of a Kevlar strip or the like.

Figure 6 shows the valve arrangement of the embodiment according to Figure 4 in an enlarged view. In this embodiment, a comparatively large filling valve 54 is located on the underneath the transverse strut 6 ( Figure 4 ) arranged area of the mast strut 4. A drain valve 56 is provided at a distance next to the mast base 18. The filling valve 54 is designed in the manner of a check valve, with a valve socket being designed as a bayonet or the like for a conventional kite or SUP pump. The emptying valve 56 is designed very simply in the manner of an air mattress valve and is opened for emptying and closed when it is inflated. A Velcro fastener is provided for securing.

In Figure 7 the end section 42 of the cross strut is shown. As explained above, this end section 42 is extended beyond the two leeks and thus protects the sail from damage. At the end sections of the mast and cross strut - as mentioned above - reinforcements 28 are arranged to protect against damage.

Figure 8 shows the mast section end section of the mast strut 4. This continues approximately in the extension of the luff 58. The upstream area of the mast strut 4 is positioned towards the mast base 18, so that the end section of the mast strut 4 on the mast base side tapers accordingly. The mast base 18 is attached to the end face of the tapered mast strut 4 via an adapter plate 60. This adapter plate 60 is connected to the appropriately designed string surface of the mast strut 4. This connection can be made by gluing, welding, sewing or other connection technology. In the illustrated embodiment, the mast strut is reinforced in this connection area, so that the adapter plate is supported over a large area. The adapter plate 60 is then tapered in the direction of the actual mast base 18. In this area, the adapter plate 60 carries the actual mast foot joint, which is formed by an elastically deflectable plastic body (power joint). This joint is provided with the reference number 62. This in turn carries a base 64, which is operatively connected to a mast foot screw 66, which is used in a conventional manner in a board-side mast foot receptacle.

As in Figure 8 is also still visible, the seams, in particular the seams in the tapering area of the mast strut 4 are covered by a protective strip 68, 70 made of an abrasion-resistant material, for example Kevlar or another plastic material. Since the surfer is usually supported on the mast foot during maneuvers in this area, the mast strut 4, in particular its seams, is thus reliably protected against damage by means of this protection 68, 70.

The maximum diameter of the adapter plate 60 corresponds to the diameter of the end section of the mast strut 4 on the mast foot side, this diameter being chosen with a view to optimum support.

Of course, further reinforcements can also be provided in this area in order to transmit the forces between the mast base and the actual rig and to protect the actual tube against damage.

The fixed connection of the mast base 18 to the sailing rig is a difference to conventional solutions in which the mast base is always attached to the rig as a separate component, for example a surfrigg.

According to the representation Figure 9 the three loop-shaped holding devices 24a, 24b, 24c are shown, all three of which are arranged approximately in that half of the longitudinal extent of the cross strut 6 which is oriented towards the mast strut 4. The front holding loop 24a is arranged in the connection area of the cross strut 6 to the mast strut 4. The two other holding loops 24b, 24c are fastened to the cross strut 6 at a distance therefrom. The diameter and the geometry of the holding loops 24 are designed with a view to optimum operability and fatigue-free guiding of the rig.

In order to avoid overloading the sail panels 2a, 2b when pulling them out of the water and, moreover, to create a kind of "water drain", the two sail panels 2a, 2b are as shown in FIG Figure 9 cut in such a way that in the transition area between the cross strut 6 and the mast strut 4 there remains an outlet opening 72, 74. These two drain openings 72, 74 are also shown in FIG Figure 10 visible. Accordingly, these drain openings 72, 74 are arranged in the sail 2 in the region of the cylindrical section 36 of the mast strut. This cylindrical region 36 ensures an optimal connection of the cross strut 6, which - as explained above - has its maximum diameter in the region between the end section 42 and the cylindrical section 36 of the mast strut 4. This area lies approximately in the area between the two holding loops 24b, 24c. In the in the Figures 4 to 10 illustrated embodiment, a sail window 76 is also provided on the overhead sail panel 2a.

Another special feature of the sailing rig 1 according to the invention is that the manufacturer offers different rig sizes, which are also optimized with regard to the body size and the weight of the user. Of course, the rigs can then also be selected depending on the expected wind strength.

As explained above, the height H (see Figure 1 ) the cross strut 6 can be varied with reference to the mast foot or the deck of the board in order to adapt the sailing rig to different body sizes. Only secondly is the sail area adjusted to different wind strengths. The sail area can can be varied by changing the length of the mast strut 4 and / or the length of the sail top strut 6 or the angle of attack of the sail top strut 6. It is also possible to have several sail sizes for each cross strut height H.

The total height of the rigs is between 4.50 and 3.00 meters. The length (width) of the cross strut 6 can range between 1.20 and 2.50 meters. The diameter of the cross strut 6 in the cylindrical section 36 is approximately in the range between 15 cm and 30 cm. The maximum diameter d of the transverse strut 6 is also in this range or slightly below.

Further variants of the sailing rig 1 are in the Figures 11 to 20 shown.

Figure 11 shows a variant of the above-described embodiments. The cylindrical section 36 of the mast strut 4 can be clearly seen in this illustration. The cross strut 6 is connected in this area, this connection taking place approximately in the middle of the cylindrical section 36. In its central region, the cross strut 6 has the maximum diameter d, which can be somewhat smaller than the diameter D of the section 36.

In this exemplary embodiment, the three holding loops 24a, 24b, 24c are approximately trapezoidal. Of course, any other suitable form can be implemented. The outer jacket of the straps can be covered with an elastic material such as foam or neoprene to improve comfort. In this embodiment, too, the holding loops 24 are arranged in half the longitudinal extent of the cross strut 6, which points towards the mast strut 4. Are indicated in the representation according to Figure 11 also the two drain openings 72, 74, which are formed in the sail 2 in the connection area of the cross strut 6 to the mast strut 4. The two catch handles 46, 48 facilitate lifting the sailing rig 1, although this always assumes a high swimming position due to the inflatable struts. The catch handle 46 is arranged at the level of the cross strut.

At the in Figure 11 In the illustrated embodiment, the sail top strut 8 is set at a comparatively large angle α to the mast strut 4. This angle of attack α can be varied depending on the sail area and the other rig geometry.

Dashed lines in Figure 11 are also the transition areas between the sail top strut 8 and the in Figure 11 upper part of the mast strut 4 and the transition regions between the cylindrical section 36 and the adjacent regions of the mast strut 4.

In this transition area indicated by dashed lines, for example, seams can be made between the individual segments of the outer skin or the bladders of the tubes can be glued.

As already explained, the mast strut 4 is set approximately V-shaped, the angle of attack β (to the vertical) of the area of the mast strut 4 above the cross strut 6 being smaller than the angle of inclination α of the sail top strut 8. The angle of incidence γ of the below the cross strut 6 area of the mast strut 4 with respect to the vertical (axis of the cylindrical section 86) is again smaller than the angles of attack α and β.

Figure 12 shows an embodiment in which the angle of attack α is designed to be significantly smaller than in the previously described embodiment, so that the sail in the top area is somewhat more pointed with less area.

Figure 13 shows an opposite interpretation, in which a very full top is achieved by increasing the angle of attack α compared to the exemplary embodiments according to FIGS. 11 and 12.

In the above-described embodiments, the sail top strut 8 is angled with respect to the mast strut. Figure 14 shows a variant in which the sail top strut 8 is practically integrated into the course of the mast strut 4, so that a continuously curved course is established. This luff curvature comes closest to that of conventional surf friggs.

In Figure 15 A variant is shown in which struts 78, 80, 82 are provided in addition to the sail top strut 8 and the cross strut 6, which are also inflatable or can also be formed by inserted battens or the like. In the event that the struts 78, 80, 82 can be inflatable, they are preferably also connected to the one-pump system and, if necessary, can be shut off using their own valves with reference to the mast strut 4.

Of course, more or less struts or battens can be used to stabilize the sail profile, as in Figure 15 are shown. It is also possible to provide short battens in the leech area, which are made of an elastic material and do not have to be removed when the surf rig is rolled up / stowed.

Figure 16 shows a variant of the embodiment according to Figure 4 , in which the mast top 44 and the end section of the cross strut 42 are extended beyond the leech 38 and the lower leek 40 in order to protect the sail. The other geometry essentially corresponds to the exemplary embodiment according to Figure 11 ,

Figure 17 shows the variant with an extended mast top 44 or end section 42 (cross strut 4) in the embodiment according to Figure 12 with a smaller angle of attack. Correspondingly, the Figures 18 . 19 . 20 one each Figures 13 . 14 or 15 corresponding exemplary embodiment, the mast top 44 and the end section 42 of the cross strut 6 being extended beyond the leech 38 and the lower leek 40.

An inflatable rig for wind-powered sports equipment and a sailing rig set with such rigs are disclosed.
