Abstract

The invention relates to an inflatable rig for wind-powered sports equipment and to a sailing rig set comprising such rigs.

Description

Segelrigg

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

Such Segelrigg can be used for example for a SUP, a windsurfboard, a sailboat or any moving by wind power sports objects.

Previously known Riggs usually have a mast made of metal or high-strength plastic, to which the luff of the sail is attached. In wind surfriggs, the sail has a mast pocket into which the tapered mast is pushed.

The construction of the sail takes place in a Windsurfrigg by means of a boom, which is attached to the mast via a boom fitting and over which the clew of the sail can be tensioned by means of a Tallje to trim the sail in the desired manner.

High-quality SUP boards are often also made with mast base mountings so that the above-described Windsurfriggs can also be mounted on a SUP board to bring windsurfing closer to a beginner, for example, while taking advantage of the stability of a SUP board.

The rigging of these aerodynamically optimized rigs, however, requires relatively large experience, furthermore, these rigs are relatively expensive due to the high quality materials, so that the use of SUP boards is rather rare. A disadvantage of such Windsurfriggs is that they are relatively heavy and in a fall relatively deep in the water, so that considerable forces must be applied to pull the rig out of the water while standing on the windsurfboard. Another disadvantage is that for stowage of the mast, the boom and the sail considerable storage space is required, so that the entrainment of the rig is difficult.

From DE 20 2013 008 701 U1 an inflatable surfing sail is known, in which the mast and a boom with two boom posts is designed to be inflatable. The basic structure thus corresponds to that of conventional solutions. The sail is then held at the boom end fitting and the mast. For stiffening the respective convexly curved and merged at their end portions boom bows they are internally provided each with an aluminum tube, which are connected by a rope. This rope is guided within a tube which extends through the sail between the boom posts.

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

In DE-OS 28 31 766 an inflatable sail is disclosed in which one or more air chambers form a mast and a transverse thereto arranged transverse strut, which span a sail together. At a foot-side end portion of the mast, a receptacle for fixing a mast base is formed.

The disadvantage of this solution is that the air chambers are designed with a relatively thin cross-section and thus the rig is not sufficiently stiff to be used even at higher wind speeds can.

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

In contrast, the invention has for its object to provide a simple structure sailing rig with sufficient stability and ease of handling. This object is achieved by a sail rig with the features of claim 1. The object is also achieved by a set of such Segelriggs according to claim 15.

According to the invention, the sail rig has a mast brace 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 build the sail rig, since the strut or struts concerned merely need to be inflated. Both the structure and the handling is very easy due to the inflatable strut, which also ensures that the rig occupies a high level of floating and thus can be pulled out of the water much more easily than conventional solutions. In this case, preferably both the mast brace and the cross brace are made inflatable. This variant has the great advantage that the trim of the sail is done practically by inflating the struts, the sail tension is variably adjustable, for example, by the respective filling pressure. According to the mast base is preferably firmly connected to the mast brace, so that a unit consisting of the actual sail, its struts and the mast base is formed and no additional component must be recognized. The connection of such a mast base to an inflatable pole strut is much easier than a variant in which the mast base releasably - as in conventional loan Windsurfriggs - is attached to the mast, since then a complex Mastfußaufnahme must be provided.

In one embodiment of the invention, the attachment of the mast base via an adapter plate, which is attached to an end face of the mast brace. By suitable design of this end face region of the mast brace and the adapter plate a reliable connection is ensured. The mast base can be designed conventionally with a so-called power joint as a joint.

According to the invention, the sail or its sail panels (sail segments) is essentially connected away from the mast towards the end of the transverse strut. This connection can be done for example by sewing or piping. According to the invention thus only a cross member is provided which spans the sail together with the mast. This is an essential difference to traditional solutions, where a boom with two boom posts is used across the mast to allow the sail to turn over. According to the invention this turning of the sail is made possible by the shape of the crossbar.

This transverse strut may have an approximately round cross section, wherein the diameter may vary along the cross strut length. In principle, however, other cross-sectional profiles can be used to optimize the sail rigging in terms of aerodynamics and / or strength.

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

The sail can be optimally designed in terms of aerodynamics, if the mast strut is designed with a sail top strut, which is employed obliquely to the mast axis and thus allows a display of the sail top. This sail top brace can be attached to the mast brace or integrated into it.

The sail top strut is preferably angled to the adjoining area of the mast brace. The handling of the Segelriggs can be further simplified if all struts are filled by means of a so-called one-pump system. That is, all struts are pneumatically connected to each other via hoses, channels or the like and filled via a single valve. Said struts are preferably designed as tubes whose longitudinal and transverse profiles are selected with regard to the aerodynamics of the sail, so that this can withstand higher wind forces. The profiling of the tubes allows an optimal design of the inflow, so that an early planing of the respective boards is guaranteed.

In one embodiment of the invention, retaining devices are arranged on both sides on the outer circumference of the transverse strut, on which the user can hold the rig or else can attach a trapeze or the like.

These holding devices may be for example straps, profile body or the like. In one embodiment of the invention, the mast strut is from the foot and from

Top her seen issued to the crossbar, so that the leading edge is curved or slightly V-shaped employed.

The structure of the Segelriggs is particularly simple if the sail is permanently attached in a suitable manner to the struts. This can, similar to a kite, be done by gluing, sewing with the struts. It is also conceivable to connect the sail via suitable releasable connecting elements, such as Velcro, zippers or the like. The following developments can also be made the subject of dependent or independent claims.

According to one embodiment, the sail rigging is provided in different sizes as sail rigging available. In particular, the height of the transverse strut, that is to say its distance from the mast base, can be varied as a function of the height of the user in order to change the rig size. As an ideal position for a boom of a conventional rig, a range between forehead and chest height has been found to be particularly suitable. Accordingly, the inventive Sail rig set designed so that users of different body sizes can choose an ideal cross brace (boom) position.

The Applicant reserves the right to apply its own sets of claims to the sailing rig and / or the following aspects.

The mast brace is preferably made approximately V-shaped to the cross member.

In the connection region of the transverse strut to the mast strut, the latter can be designed approximately cylindrically.

End sections of the cross brace and the mast brace may be extended beyond the sail. The mast brace may be formed approximately cylindrical in the connection region of the transverse strut. Starting from this, preferably cylindrical, area, the mast brace can taper towards the sail top and / or the mast base.

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

Aufholhandles are preferably provided on an inflow side of the mast brace. Due to the high floating position of the Segelriggs catch-up is very easy, so that the use of a "Stutschot" (Aufholleine) can be dispensed with, as arranged on the front of the mast strut Aufholhandles sufficient to pull the Segelrigg with minimal effort from the water.

A sail top strut can be set at an angle to the mast strut. However, the mast brace can also be curved throughout. In this case, the angled region of the mast strut can be made in one piece with this or executed via a sail strut connected to the mast strut. In addition to the sail top strut and the cross strut, further canvas struts may be provided.

The angle of attack of the sill brace to the mast brace may vary depending on the size of the sail.

To form a sail rig set (S, M, L, ...) can be varied in addition to the height position of the cross brace and the angle of the sail top brace to provide an adaptation to the wind strength and on the other hand for each body-sized optimal sail rig so that this can also be used in the training.

The Applicant reserves the right to make a claim that the sail rigging sizes of the sailing rigging are determined respectively by the height position of the crossbar, the angle of attack of the sail top brace and the total length of the pole brace and the cross brace, graded sizes of sail rigs with a given position of the sail rig Cross brace or a boom are not yet known.

The dimensions of the mast brace and the cross brace mentioned in the specific description can likewise be made the subject of claims.

To avoid damaging the mast-foot-side region of the mast strut, the latter, in particular in the seam area, is designed with reinforcements / protective elements.

To assist in draining water, drainage holes, preferably in the sail, may be provided.

Preferred embodiments of the invention are explained in more detail below with reference to schematic drawings. Show it:

Figure 10 is a partial view of the Segelriggs according to Figure 4 and

Figures 1 1 to 20 further variants of Segelriggs invention. The sail rig 1 has according to Figures 1 and 2, a sail 2, by means of a

Pole strut 4, a cross strut 6 and a sail top strut 8 is clamped. All struts 4, 6, 8 are designed as tubes. Such tubes usually have an airtight bladder, which are surrounded by a robust, visible in the outer skin. The filling of the tubes takes place via one or more valves 10. In the illustrated exemplary embodiment, a so-called one-pump system is realized in which all struts are pneumatically connected to one another. In the illustrated embodiment, the pneumatic connection of the cross member 6 is made to the mast strut 4, for example via a hose 12, which is designed with a clamp 14, so that the two air volumes are shut off against each other and thus the rig remains floatable even in the event of leakage. In the illustrated embodiment, the sill strut 8 is integrally formed with the mast brace 4, wherein in the transition region of the two tube forming this structure forming a reinforced seam 16 is provided on the visible outer skin. Such reinforced seams 16 are also provided on other highly stressed areas. The bladder is executed in the same way. In the connection region of the transverse strut 6 to the mast strut 4, a reinforcement 22 is also attached to this. The sail areas 2 above and below the crossbar 6 can be designed both flat and with a profile. The sail 2 may be composed of several panels, which are preferably connected by sewing or gluing with the struts 4, 6, 8. The connection plane preferably extends approximately along a median plane of the struts 4, 6, 8. This will be explained with reference to the detail section according to FIG. 1 a. Visible in this sectional view is the roughly round cross section of the transverse strut 6, in which a part of the abovementioned bladder 30 is accommodated, which can be filled via the valve 10. According to FIG. 1a, the sail surface of the sail panels 2a, 2b located at the top and bottom in FIG. 1a extends approximately in the middle plane 32 of the cross strut 6 indicated by dot-dash lines. In other words, the two sail panels 2a, 2b are approximately in the middle attached to the crossbar 6. This attachment is preferably carried out by gluing or sewing, wherein kederförmige reinforcements 34 are provided in the embodiment of Figure 1 a, which allow an optimal connection between the sail 2 and the cross member 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 transverse strut 6 of two half profiles, which are attached to both sides of the sail 2. Of course, deviating from the circular cross-sectional shape cross sections are realized. The course of the profile is chosen in such a way that the sail can be given the desired sail profile during use, whereby this sail profile naturally also depends on the filling pressure of the struts. Furthermore, the profile of the crossbar is designed with regard to the optimal rigidity of the rig. In principle, it is also possible, the sail only partially or sliding on the

To hold cross member, so that the sail profile is adjustable via suitable trim devices in the cross brace longitudinal direction.

At a foot-side end portion of the mast brace 4, a receptacle for an indicated mast base 18 is provided. This is attached to the recording and thus remains on Segelrigg. Due to the filling pressure, which can be in the range of 0.5 to 2 bar, the rig 2 is stabilized, wherein the filling pressure - as stated - among other things, determines the sail trim. In principle, additional facilities for trimming the sail can be provided. (Eg batten as a modern windsurf sail)

In the illustrated embodiment, the mast strut 4 is slightly V-shaped issued to the crossbar 6 - characterized the optimum bending line of a mast of a windsurfing rig is achieved. The cross-section of the struts 4, 6, 8 is also optimized aerodynamically and in terms of strength. In the illustrated embodiment, increases according to Figures 1 and 2, the diameter D of the mast brace 4 toward the cross member 6, wherein the mast brace 4 is cylindrical in the connection region of the cross member 6. This area is provided with the reference numeral 36 in FIG. The foot-side diameter and the sail-top-side diameter of the mast strut 4 and the sail-top strut 8 are significantly smaller than the maximum cross-section in the region of the connection of the transverse strut 6. This has its maximum diameter d approximately in the middle region and tapers towards the leech of the sail 2 or for connection to the mast brace 4.

For holding the sail 2, a holding device 20 is provided on both sides approximately parallel to the transverse strut longitudinal axis. This holding device 20 may, for example, according to Figure 3 have a stable webbing 26 to which a plurality of straps 24a, 24b, 24c are held. These straps 24 may be made of webbing or the like or relatively rigid as a trapeze lamps. The reinforcement can be made so that the straps 24 can be displaced.

Of course, such a holding device 20 is formed as in a Surfrigg on both sides of the transverse strut 6. Alternatively, the holding device 20 may also be formed by a profile body or the like, which is attached to the stable outer skin of the transverse strut 6. This holding device 20 makes it possible to keep the Segelrigg 1 or hook a trapeze. The cross-sectional profile of the tubes is clearly visible in the volume model according to FIG. As explained rejuvenate the cross strut 4, the sail top strut 8 and the cross strut 6 towards their end portions, so that a statically stable structure is created with optimal aerodynamics.

As mentioned above, the sail rig 1 is not limited to use with SUP or windsurfing boards but can also be used in sailing, canoes, beach sailors, landboards, etc. in general.

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

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

To inflate a conventional kite or SUP pump can be used. A variant of the above-described Segelriggs will be explained with reference to FIGS 4 to 10.

In the variant illustrated in FIG. 4, the leech 38 and the underlie 40 terminate 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 over the each Liek out extended and thus protect the sail when grinding on the ground against damage.

In the illustration according to FIG. 4, one also clearly sees the mast foot 18 integrated in the sail rig 1, which is articulated and thus permits an angle of the sail rig 1 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, although a difference is that in Surfriggs and the like Mastfuß 18 mounted on the board and then inserted into the mast, while it is integrated in the sail rig according to the invention 1 in this.

To simplify the recovery of the sail 2 from the water 4 Aufholhandles 46, 48 are provided on the inflow surface of the mast strut shown in Figure 5. The handle 46 lying in FIGS. 4 and 5 is provided approximately in the extension of the transverse strut 6. The underlying Aufholhandle 48 is mounted in the area between the mast base 18 and the overhead Aufholhandle 46. As can be seen in particular from the illustration in Figure 5, the mobile phones are not centered on the seam 50 of the pole strut 4 but obliquely thereto, with one handle end portion to the left of the seam and the other end portion to the right of the seam 52 is arranged - the mobile phones 46, 48 thus cross, so to speak, the seam 52, which in turn is protected against wear by means of a Kevlar strip or the like.

Figure 6 shows the valve assembly of the embodiment of Figure 4 in an enlarged view. In this exemplary embodiment, a comparatively large filling valve 54 is arranged on the region of the mast strut 4 lying below the transverse flow 6 (FIG. 4). At a distance next to the mast base 18 out offset a drain valve 56 is provided. The filling valve 54 is formed in the manner of a check valve, wherein a valve stub is designed as a bayonet or the like for a conventional kite or SUP pump. The drain valve 56 is very simply designed in the manner of an air mattress valve and is opened for emptying and closed during inflation. To secure a Velcro closure is provided.

In Figure 7, the end portion 42 of the cross member is shown. As explained above, this end portion 42 is extended beyond the two Lieks and thus protects the sail from damage. As mentioned above, at the end portions of the mast and cross braces, reinforcements 28 are arranged for protection against damage.

Figure 8 shows the mastfußseitigen end portion of the mast brace 4. This continues approximately in extension of the sail luff 58 continues. The upstream area of the mast strut 4 is employed to the mast base 18, so that tapers according to the mast foot-side end portion of the mast strut 4. The mast base 18 is attached via an adapter plate 60 to the end face of the tapered mast strut 4. This adapter plate 60 is connected to the corresponding trained Strinfläche the mast strut 4. This connection can be made by gluing, welding, sewing or other connection technology. In the illustrated embodiment, the mast brace is reinforced in this connection region, 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 foot 18. In this area, the adapter plate 60 carries the actual mast ankle, which is formed by an elastically deflectable plastic body (Powerjoint). This joint is provided with the reference numeral 62. This in turn carries a base 64, which is operatively connected to a mast base screw 66, which is conventionally used in a board-side Mastfußaufnahme. As can also be seen in FIG. 8, the seams, in particular the seams, are

Seams in the tapered region of the mast brace 4 covered by a protective strip 68, 70 of an abrasion-resistant material, such as Kevlar or other plastic material. Since the surfer is supported as usual in maneuvers in this area on Mastfuß, thus the mast brace 4, in particular their seams on this protection 68, 70 reliably protected against damage.

The maximum diameter of the adapter plate 60 corresponds to the diameter of the mastfußseitigen end portion of the mast strut 4, wherein this diameter is selected with regard to the optimal support.

Of course, further reinforcements may 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 sail rig is a difference to conventional solutions in which the mast base is always recognized as a separate component to the rig, for example, a Surfrigg. In the illustration according to FIG. 9, the three loop-shaped holding devices 24a, 24b, 24c are shown, all of which are arranged approximately in that half of the longitudinal extension of the transverse strut 6, which is oriented towards the mast strut 4. In this case, the front retaining loop 24a is arranged in the connection region of the transverse strut 6 to the mast strut 4. The other two retaining loops 24b, 24c are attached at a distance to the cross member 6. The diameter and the geometry of the straps 24 are designed in view of the optimal operability and a fatigue-free guiding of the rig.

In order to avoid an overload of the sail panels 2a, 2b when pulling out of the water and beyond to create a kind of "water drain", the two sail panels 2a, 2b as shown in Figure 9 cut so that in the transition region between the crossbar 6 and The two outlet openings 72, 74 are also visible in the illustration according to Figure 10. Accordingly, these discharge openings 72, 74 are arranged in the sail 2 in the region of the cylindrical section 36 of the pole strut 36 ensures optimum connection of the transverse 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 region lies approximately in the region between the two holding loops 24b, 24c the embodiment shown in Figures 4 to 10 is located on the overhead Seg elpaneel 2a further provided a sail window 76.

Another peculiarity of the sailing rig 1 according to the invention is that different sizes of rigging are offered by the manufacturer, which are optimized inter alia also with regard to the height and weight of the user. Of course, the rigs can then be selected depending on the expected wind strength. As explained above, the height H (see FIG. 1) of the transverse strut 6 with respect to the mast foot or the deck of the board can be varied in order to adapt the sail rig to different body sizes. Only in the second place is an adaptation of the sail area to different wind strengths. This can be the sail area By varying the length of the mast strut 4 and / or the length of the sill strut 6 and the angle of attack of the sill strut 6 can be varied. It is also possible to execute several sail sizes for each transverse strut height H. The total height of the rigs is in the range between 4.50 and 3.00 meters. The

Length (width) of the crossbar 6 can be in the range between 1, 20 and 2.50 meters. The diameter of the transverse strut 6 in the cylindrical section 36 is preferably approximately in the range between 15 cm and 30 cm. The maximum diameter d of the

Querstrut 6 is also in this area or slightly below.

Other variants of the Segelriggs 1 are shown in Figures 1 1 to 20.

Figure 1 1 shows a variant of the above-described embodiments. It can be clearly seen in this illustration, the cylindrical portion 36 of the mast strut 4. In this area, the cross member 6 is connected, wherein this connection takes place approximately in the middle of the cylindrical portion 36. The transverse strut 6 has in its central region the maximum diameter d, which may be slightly smaller than the diameter D of the section 36. The three holding loops 24a, 24b, 24c are designed approximately trapezoidal in this embodiment. Of course, any other suitable form can be realized. The outer sheath of the straps may be sheathed with an elastic material, such as foam or neoprene, to improve comfort. Also in this embodiment, the holding loops 24 are arranged in the half of the longitudinal extent of the transverse strut 6, which points to the mast strut 4. Also indicated in the illustration according to FIG. 1 1 are the two drainage openings 72, 74 which are formed in the sail 2 in the connection region of the transverse strut 6 to the mast strut 4. The two Aufholhandles 46, 48 facilitate the lifting of Segelriggs 1, although this always assumes a high level of floating due to the inflatable struts. The Aufholhandle 46 is arranged at the level of the cross member.

In the embodiment shown in Figure 1 1, the sail top strut 8 is employed with a relatively large angle α to the mast brace 4 out. This appendix Setting angle α can be varied depending on the sail area and the other rigging geometry.

Dashed lines in Figure 1 1 are also the transition areas between the sail top strut 8 and the upper part of the mast strut 4 in Figure 1 1 and the transition areas between the cylindrical portion 36 and the adjacent areas of the mast strut. 4

In this transition regions indicated by dashed lines, for example, seams can be made between the individual segments of the outer skin or a bonding of the bladder of the tubes.

As already explained, the mast strut 4 is employed approximately V-shaped, the angle of attack β (to the vertical) of the region of the mast strut 4 located above the cross strut 6 being smaller than the angle of attack α of the sail strut 8. The angle of incidence γ of the below the cross strut 6 located portion of the mast brace 4 with respect to the vertical (axis of the cylindrical portion 86) is in turn smaller than the angle of attack α and ß. Figure 12 shows an embodiment in which the angle of attack α is significantly smaller than in the embodiment described above, so that the sail in the top area is slightly sharper with less surface.

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

In the embodiments described above, the sill strut 8 is angled with respect to the mast strut. FIG. 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 surfriggs. FIG. 15 shows a variant in which, in addition to the sail top strut 8 and the cross strut 6, struts 78, 80, 82 are provided, which are likewise inflatable or else can be formed by inserted sail battens or the like. In the event that the struts 78, 80, 82 can be designed to be inflatable, they are preferably also connected to the one-pump system and can optionally be shut off via their own valves with respect to the mast strut 4.

Of course, to stabilize the sail profile more or less Struts or battens are used, as shown in Figure 15. It is also possible to provide short battens in the leech area, which consist of an elastic material and must not be removed during rolling / damming the Surfriggs.

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

FIG. 17 shows the variant with extended mast top 44 or end section 42 (transverse strut 4) in the embodiment according to FIG. 12 with a smaller angle of attack. Correspondingly, FIGS. 18, 19, 20 each show an exemplary embodiment corresponding to FIGS. 13, 14 and 15, wherein in each case the mast top 44 and the end section 42 of the transverse strut 6 are extended beyond the leech 38 and the underbelly 40.

Disclosed are an inflatable rig for wind-powered sports equipment and a sail rig set with such rigs. LIST OF REFERENCES:
