Definitions

  • the invention relates to a hand-supported wing rig for wind-powered sports, such as foil surfing, according to the preamble of patent claim 1.
  • Such a wing rig is described under the name "Slingwing” on the Internet. It is basically a kite with a leading edge and a single strut that are inflatable. On the central strut and on the leading edge there are holding loops, which the user uses to hold the inflatable wing rig during use, for example when foiling or ice skating or skiing.
  • This inflatable wing rig which is adapted to the aerodynamics of kites, is severely deformed during use, especially at the high speeds achieved when foiling, and the aerodynamics are thus impaired.
  • a rigid wing rig in which the leading edge and a boom are formed by a complex tubular construction that spans a canvas (canopy).
  • the leading edge is curved in an arc shape as seen in a plan view.
  • the tree is supported by a multitude of struts at the leading edge. These struts are designed in such a way that they give the leading edge a concave structure in a front view, ie seen in the direction of flow of the wing rig, according to which the end sections (tips) of the wing rig are issued upwards from a central apex of the leading edge.
  • a disadvantage of this solution is that due to the complex structure of the boom and the leading edge, the total weight of the wing rig is very high, so that it can only be used in water sports with the appropriate buoyancy devices. Another disadvantage is that the erection and dismantling of the wing rig due to the complex pipe structure takes a lot of time. This hard tubular structure of the leading edge and the tree also poses a significant risk of injury to the user in a skid fall.
  • the leading edge is formed by two V-shaped masts, which are connected to one another via a central boom and support struts.
  • This wing rig also has a considerable weight due to its tubular structure, which makes handling significantly more difficult, especially in water sports.
  • the invention is based on the object of creating a hand-supported wing rig that enables a simple structure and maintains an aerodynamically optimized profile even at high driving speeds.
  • the hand-supported wing rig is suitable for wind-driven sports, for example foil surfing, and the high speeds associated therewith.
  • the wing rig has a leading edge, preferably designed to be inflatable, from which a tree extends, the leading edge and the tree open a canopy.
  • the wing rig is held in particular on the tree during use.
  • the leading edge is designed curved from a connection of the tree away to the leech (trailing edge) of the canopy in a top view approximately arc-shaped, delta-shaped, U-shaped or C-shaped.
  • the leading edge is approximately V-shaped or U-shaped in a front view seen in the direction of flow when there is no flow or no load, with this profile converging towards the tree.
  • the profile opens upwards, away from the driver, during use.
  • V or U profile and the arched, delta-shaped or U- or C-shaped design of the leading edge result in an aerodynamic optimized profile, which on the one hand opens automatically in gusts and thus reduces the resulting pressure to be supported by the user and on the other hand generates low aerodynamic resistance even at high driving speeds.
  • a maximum driving speed or also a maximum lift for jumps or the like can be generated depending on the direction of the wind.
  • the tree is preferably designed as a rigid, non-inflatable component.
  • the term "rigid component” is understood to mean a structure formed from a largely dimensionally stable material, but this can be easily dismantled or else made telescopic.
  • the boom is designed to make holding the wing rig easier during use.
  • the tree is preferably designed with a covering that improves grip/friction.
  • the approximately V- or U-shaped profile runs away from the leading edge towards the trailing edge of the canopy. That is, the entire wing rig profile is profiled in the front view (seen in the direction of flow) opening upwards.
  • the efficiency of the wing rig is further improved when the V or U angle is maximum in the boom attachment area and decreases towards the tips. It is preferred if the angle of inclination to the horizontal (parallel to the connecting line through the tips) in the apex area is between 10° and 30°, preferably more than 15°, particularly preferably about 20°.
  • the "angle of inclination” is understood to mean the angle that the respective area of the leading edge makes when the wing rig is positioned parallel to the water surface/usable surface, i. H. to the horizontal.
  • the opening angle between the leading edge areas that are inclined towards one another then corresponds to the difference between 180° and twice the angle of inclination (additional angle to 180°).
  • the trailing edge (leech) is designed with a corresponding profile angle.
  • the aerodynamics are further improved if the angle of inclination in the tip area is between 0° and 20°, preferably more than 1°, preferably about 5°.
  • the wing rig is designed in such a way that the mean angle of inclination, i. That is, the angle from the apex of the leading edge to the respective tip is 5° to 20°, preferably about 10°.
  • the boom can be made telescopic or made up of several interchangeable sections.
  • the outlay in terms of device technology is particularly low if the tree is fastened to the leading edge and the trailing edge in an exchangeable manner by means of a holder. This way a single boom can be used for multiple wing rigs.
  • the flight stability of the wing rig is further improved if the boom holder is designed in such a way that it prevents the leading edge from rotating about its longitudinal axis.
  • the holder encompasses the leading edge in sections and thus prevents rotation.
  • the bracket can also enforce the leading edge.
  • corresponding receptacles for the holder or the tree must then be formed on the leading edge.
  • a channel should also be provided into which the bracket or tree can be inserted.
  • the boom is designed without bracing.
  • such a solution is weight-optimized and, on the other hand, it enables the user to hold the boom and thus the wing rig variably depending on the respective driving maneuver and the environmental conditions.
  • the center of canopy is at least 30 percent, preferably more than 40 percent of the distance between the apex of the leading edge and the trailing edge (leech) away from the leading edge.
  • leading edge and/or the canopy can be stiffened by means of stiffening elements, for example battens.
  • These sail battens can in turn be curved and/or tapered to give the wing profile a profile.
  • a batten extends from the leading edge to the trailing edge, the batten being positioned so that it is in a vertical plane with the boom (when the wing rig is horizontal).
  • a handle can be provided in the connection area of the tree, preferably on the leading edge.
  • the wing rig In order to prevent separation from the user in the event of a fall, the wing rig is equipped with a safety leash.
  • the applicant reserves the right to direct a secondary claim to a wing rig with the above-described V- or U-shaped profile and a rigid, non-inflatable leading edge.
  • the holder for connecting the tree to the leading edge can be formed, for example, by a profile piece that partially surrounds the leading edge and is attached to the leading edge using suitable fastening means. The tree is then inserted into the profile piece or connected to it in some other way.
  • a bracket for the tree is formed on the leading edge using profile parts or canvas. These profile parts in turn surround the leading edge in sections, so that the leading edge is prevented from rotating during use.
  • the tree preferably extends from the leading edge to the trailing edge without being directly or firmly connected to the canopy in the areas in between, so that practically the entire length of the tree is available as a grip area. This ensures that the holding of the wing rig during any maneuver can be chosen in an optimal way according to the user's preferences. Furthermore, the profile depth can be adjusted by adjusting the boom length.
  • the structure of the wing rig is designed in such a way that the opening angle in the area of the trailing edge is reduced in the flow condition, i.e. when using the wing rig.
  • the change in the opening angle can be greater in the trailing-edge area than in the leading-edge area.
  • the boom is preferably attached to the apex of the leading edge in the area facing away from the canopy.
  • the attachment is such that the wing rig can be swiveled/adjusted to the side by turning the boom around its longitudinal axis - this would not be possible with loops (handles), as these are not rigid and therefore no torque can be applied.
  • FIG 1 the use of a wing rig 1 according to the invention for driving a foil board 2 is shown.
  • a surfer 4 holds the wing rig 1 with his hands only and adjusts it with respect to the wind depending on the desired direction of travel (upwind, downwind, downwind) or on the lift to be set, for example when jumping or adjusting the ride height.
  • the wing rig 1 has an inflatable leading edge 6, which in plan view (from above in the figures 1 and 2 ) is approximately arcuate, preferably approximately delta-, C- or U-shaped and extends with their tips 8, 10 up to a trailing edge 12 of a canopy 14 of the wing rig 1.
  • this canopy 14 is supported on the one hand by the leading edge 6 and on the other hand by a tree 16, which is explained in more detail below (see figure 3 ) stretched.
  • the surfer 4 holds the wing rig 1 only on the boom 16, which is downwards (as viewed from figure 1 ) protrudes.
  • the tree 16 is preferably provided with a covering that simplifies/optimizes gripping and holding.
  • the Leading Edge 6 is visible both in plan ( figure 2 ) as well as in a front view - seen in the direction of flow - (see figure 4 ) V-shaped or U-shaped, with the V/U widening upwards, ie away from the surfer when viewed from the front. How figure 1 can be removed, the trailing edge 12 and thus the entire canopy surface 14 is set in a V (or U) shape when viewed from the front.
  • figure 2 shows a plan view of the wing rig 1 according to FIG figure 1 .
  • the approximately arched or delta-shaped, approximately U-shaped or C-shaped leading edge 6 can be seen, which extends to the trailing edge 12 of the canopy 14 .
  • the leading edge 6 is formed in the manner of a kite by a front tube, in which a bladder is accommodated, which is inflated via a valve, the pressure being selected such that the structure of the wing rig 1 is maintained even at high wind speeds and driving speeds is guaranteed.
  • the leading edge 6 is formed by a large number of tube segments 18a, 18b, 18c, 18d, 18e (for the sake of simplicity, only half of the trailing edge 12 is provided with reference symbols), whose angle of incidence ⁇ to the horizontal is in figure 2 (ie, for example towards a connecting line between the two tips 8, 10) from an apex 20 to the tips 8, 10 increases.
  • This angle of attack ⁇ is drawn in as an example for the tube segment 18a.
  • the center of area (center of canopy) is identified by reference number 22 .
  • This centroid 22 is offset from the apex 20 by at least 40 percent of the distance between the apex 20 and the corresponding apex 24 of the trailing edge 12 .
  • the distance between the parting 20, 24 is in figure 2 marked with the reference a.
  • the distance b between the vertex 20 and the centroid 22 is at least 40 percent of the distance a.
  • This center of area 22 is selected in such a way that the surfer 4 can grip the tree 16, which will be explained in more detail below, in an optimal manner and can thus support the acting wind forces in order, for example, to travel an optimal upwind course.
  • a central center batten 23 and two battens 27a, 27b offset towards the tips 8, 10 are provided, which extend between the leading edge 4 and the trailing edge 12 and are inserted into corresponding batten pockets of the canopy 14.
  • This insertion takes place in a manner known per se with a certain pretension which is selected according to the desired profiling or can also be changed in order to be able to adapt the profile to different wind speeds.
  • the Tube forming the leading edge 10 spans the canopy 14 together with the boom 16 and the sail battens 23, 27, with the boom 16 also engages the apex 24 of the trailing edge 12 of the canopy 14 and is preferably not connected to the canopy 14 therebetween.
  • the center batten 23 extends parallel to the longitudinal extent of the boom 16 between the leading edge 6 and the trailing edge 12. Accordingly, this batten 23 also engages on the one hand in the apex 20 of the leading edge 6 and on the other hand in the apex 24 of the trailing edge 12.
  • the boom 16 and the center batten 23 are therefore in the same vertical plane as in figure 2 perpendicular to the drawing plane and in figure 3 lies in the drawing plane.
  • the space between the boom and the batten 23 / canopy 14 is therefore free, so that the surfer can freely choose his grip position depending on the manoeuvre/course.
  • the Leading Edge 6 is also perpendicular to the plane of the drawing figure 2 profiled. Specifically, the leading edge 6 is V-shaped away from the apex 20 towards the tips 8, 10, with the V (also called opening angle ⁇ )--as in FIG figure 1 shown - upwards, ie away from the tree 16 opens. This V-profile is also formed accordingly in the area of the canopy 14 . This is achieved, inter alia, in that the tree 16 has the apex 24 in the representation according to FIG figure 3 down, ie stretches away from the tips 8, 10 and thus forms the V-shape, which is determined by the opening angle ⁇ .
  • the structure of the wing rig 1 is designed in such a way that this opening angle ⁇ decreases in the flow state, since the tips 8, 10 deflect upwards (away from the surfer 4) due to the load.
  • the tree 16 acts on the area of the apex 20 of the leading edge 6 that is at a distance from the canopy 14 (located below).
  • the V shape is particularly evident in the front view figure 4 visible.
  • the leading edge 6 formed by the tube is arranged pointing towards the viewer.
  • the canopy 14 is set in a corresponding V-shape.
  • the angle of inclination ⁇ of the leading edge 6 is maximum in the area of the apex 20 .
  • this angle of inclination is ⁇ , ie the angle between the horizontal (parallel to the connecting line of the tips 8, 10) and the tube segment 18a is approximately 20°, for example.
  • the next tube segment 18b is then slightly flatter, so that the angle is 15°, for example.
  • the angle of inclination of the following segments 18c, 18d, 18e is then flatter again, with the angle of inclination ⁇ in the region of segment 18c being able to be 5°, for example.
  • the “mean” angle of inclination ⁇ seen over the entire wing rig 1 is 10°, for example, so that the “mean” opening angle is then about 160°.
  • the tree 16 is designed without braces - this is a major difference from the complex structures described above, in which the tree with a variety of transverse and Oblique struts is performed.
  • the tree 16 can be detachably fastened to the apex 20 of the leading edge 6 via a holder 25 .
  • the holder 25 has a support bracket 26, which is formed according to the outer contour of the apex 20 and this partially surrounds. This gripping takes place in such a way that, with comparatively high wind pressure, the tube rotates, d. That is, the tube segments 18a forming the apex 20 in the direction of the arrow, and thus twisting of the profile, are reliably prevented.
  • the support bracket 26 is then followed in the direction of the tree 16 by a receptacle 28 into which the tree 16 is inserted.
  • the end sections of the support bracket 26 and the receptacle 28 are connected via a curved handle 30, which makes it easier for the surfer 4 to handle the wing rig 1 before and after use.
  • the wing rig 1 can be held by the handle 30 in order to allow it to blow out in the wind.
  • the bracket 25 and the tree 16 are preferably made of a light material, for example aluminum, fiber-reinforced plastic, carbon fiber materials or other high-strength lightweight materials. Due to the simple structure of the boom 16, this affects the overall weight of the wing rig 1 insignificantly.
  • figure 5 shows a side view of a variant of the above-described embodiment of a wing rig 1.
  • the view corresponds approximately to that of FIG figure 3 . That is, visible in this view is the tip 10 with the V-shaped leading edge 6, which has its lowest point in the area of the apex 20.
  • the apex 24 of the trailing edge 12 is descended from the tree 16 (as viewed in figure 5 down) tense.
  • the holder 25 of the tree 16 in turn has a receptacle 28 into which the tree 16 is inserted or which is connected to the tree 16 in some other way.
  • the apex 20 is based according to figure 6 at the top of the recording 28 from.
  • a lightweight, approximately U-shaped handle 32 extends away from the receptacle 28, the end section of which is offset at a distance from the point where the apex 20 rests on the receptacle 28, i.e. towards the canopy 14 at the apex 20 formed by the tube segments 18a attacks.
  • the handle 32 Due to the U-structure of the handle 32, the wing rig 1 can be held in a simple manner for blowing out.
  • the handle 32 is designed as a framework structure.
  • the attachment of the receptacle 28 and the end section 34 to the apex can be formed using suitable fixing elements on the tube segments 18a. These fixing elements are preferably designed in such a way that the handle 30 is detachably connected to the leading edge 6 (front tube).
  • handle 32 can also be designed as a loop on the inflow side of the leading edge 6, so that the surfer can let the wing rig 1 wave out while holding it in his hand, for example.
  • figure 7 shows an exemplary embodiment in which the holder 25 is designed as a flat body which is designed to encompass the trailing edge 6 or the tube segments 18a in sections.
  • This flat mount can be designed as a molded body, for example.
  • the holder 25 is made of canvas, which is connected to the apex 20 of the leading edge 6 and is possibly stabilized by suitable stiffening elements. The tree 16 can then in turn be inserted into this holder 25 .
  • the holder 25 is designed in such a way that the tube (leading edge 6 ) is prevented from rotating in the direction of the arrow by being supported by the tree 16 .
  • the front tube is designed with a continuous bladder.
  • a separate bladder is preferably used for each half of the wing rig, whereby between these two bladders according to the illustration in figure 8 a Support channel 36 remains, in which the tree 16 is inserted.
  • This support channel 36 can be formed, for example, by a piece of pipe that diametrically penetrates the front tube.
  • This support channel 36 is formed between the two bladders of the two wing rig halves (left, right).
  • a bearing ring 40 is formed on an outer shell 38 of the front tube (leading edge 6), which runs as an extension of the support channel 36 and through which the boom 16 passes.
  • This bearing ring 40 absorbs the compression forces and is designed in a similar way to the support rings of the kite valves that are commonly used.
  • a similar support ring 42 is provided opposite the bearing ring 40 on the inside of the outer shell 38 on which the in figure 8 left end portion of the tree 16 is supported. That is, the boom 16 is connected to the outer shell 38 in a non-positive and positive manner, so that the apex 20 and thus the front tube are prevented from twisting in the direction of the arrow. As explained, the tubular support channel 36 is connected to the bearing ring 40 on the one hand and the support ring 42 on the other hand, so that the tree 16 is reliably fixed in position.
  • Such a solution has the advantage that the bearing rings 40 and the support rings 42 can be used for practically any front tube diameter—only the length of the support channel 36 has to be adjusted.
  • the boom 16 is supported very stably, so that the holding forces introduced by the surfer 4 and also the compression forces transmitted by the front tube are reliably absorbed without the boom 16 being excessively deformed.
  • the support channel 36 and the rings 40, 42 are preferably designed as plastic injection molded parts.
  • the canopy 14 can be stabilized using battens or the like. These sail battens can be conical or profiled in order to optimize the inflow profile of the canopy 14.
  • the leading edge 16 can also have suitable Stiffening elements are stiffened so that the wing rig 1 keeps the aerodynamically optimized shape shown even under high loads.
  • These sail battens or stiffening elements can also be designed as carbon fiber tubes or the like.
  • the sail battens are profiled in such a way that they are initially adapted to the diameter of the leading edge 6 (front tube) and then support the canopy 14 .
  • additional or alternative sail battens can be inserted from the trailing edge 12 into the canopy 14.
  • wing rig 1 In order to prevent the wing rig 1 from drifting off in the event of a fall, it is connected to the surfer 4, in particular to his arm, via a safety leash 44.
  • a hand-supported wing rig is disclosed, which is preferably designed with an inflatable leading edge, this being designed to widen upwards (away from the surfer) in an approximately V-shaped or U-shaped manner in the direction of flow.
