Description

Device for setting a steering kite system

FIELD OF THE INVENTION

The present invention is in the field of steering kite systems, in particular it relates to a device for adjusting a steering kite system. BACKGROUND OF THE INVENTION

Lenchy kite systems are used in the prior art to let themselves be drawn by wind power on a board or surfboard over the water - and temporarily also in the air. A steering kite system 10, as used in the prior art, is shown in Figure 1 from a lateral perspective (Figure la) and from a frontal perspective (Figure lb). The steering kite system 10 comprises a screen or "kite" 12, a handlebar or "Bai '" 14 and a harness 16. The screen 12 and the harness 16 are connected via a pull line 18 with each other, the pull cord 18 each tensile with the Screen 12 and tensile with the harness 16 is connected. As shown in Figure 1, the pull line 18 can also split into several lines, over which the tensile connection with the screen 12 is made. The handlebar 14 and the screen 12 are interconnected by two control lines 20, wherein one end of a control line 20 with a corresponding side end of the screen 12 is connected tensile strength. The respective other end of each control line 20 is connected in a tension-proof manner to an associated end of the handlebar 14. In the middle of its front side, the screen 12 is furthermore connected in a tension-proof manner to a securing line 22, which is connected to the trapezoid 16 at its other end. In an emergency, the safety line 22 can be released from the harness 16.

When using the steering kite system 10, a train of wind-driven screen 12 is transmitted to the trapezoid 16 via the hauling line 18. This traction allows the trapezoidal athlete to pull himself over the water on a board (not shown). The sportsman can steer the screen 12 by pulling on one side of the screen with the help of the handlebar 14 via one of the two control lines 20.

The athlete also has the option with the help of the handlebar 14 to change the angle of attack of the screen 12. When the athlete pulls the handlebar 14 horizontally (so-called "Anpowem"), the rear part of the umbrella 12 is pulled down relative to the front and the umbrella 12 receives more wind the traction force on the athlete is increased via the leash 18. If the athlete moves the handlebar 14 horizontally away from himself or gives in to the train (so-called "depowering"), then the rear part of the shield moves upwards in relation to the front side so that the screen 12 offers less resistance to the wind. The screen decreases and the traction over the tug 18 on the athlete is reduced. A disadvantage of the described steering kite system 10 is that the construction is quite complex. During construction, the long lines are laid out individually and separately on the bank of the water. For this it is often necessary to untangle or disentangle the lines time consuming. Another disadvantage is that the starting and landing of the described steering kite system 10 is often not easy depending on the environmental conditions. When the athlete is connected to the glider 12 via the harness 16 and lines 18, 20, 22, a second person usually helps him to start the glider 12. Here, the athlete must be careful to start the glider 12 in a controlled manner without that the umbrella 12 or the lines 18, 20, 22 come into contact with surrounding obstacles, for example with trees, and without endangering other persons. The same applies to the landing of the glider 12. Controlled and safe starting and landing is more difficult the less space is available and the longer the lines 18, 20, 22 are.

Most currently used steering kite systems 10, as previously described, have a substantially constant line length. For some manufacturers, it is possible to change the line length over adjusters in the cm range in order to influence the angle of attack of the screen 12. With these systems, the distance between the glider 12 and the athlete can not be easily changed, for example, to adapt the system flexibly to changing wind conditions or to start and land the glider 12 more easily. However, steering kite systems with an adjustable line length have also been proposed. An example of this is described in US 2004/0065780 AI. US 2004/0065780 AI describes a special handlebar, over which the athlete can extend and shorten all lines together. In this device, the lines are linked at one end to the screen and connected at its other end in each case with an associated winding coil. All coils are arranged on a common axis which is parallel to the handlebar and forms a common unit with the handlebar. Although this device has the advantage of a simplified starting and landing and a simplified assembly and disassembly, but at the cost of a relatively bulky for the athlete handlebar.

A further disadvantage of this device is that during arrival and depowering the contact with the screen via the control lines is less direct and that the wound-up traction lines can not be connected to the trapeze via a conventional quick-release system. The arrival and depowering takes place in the US 2004/0065780 AI not a direct and almost resistanceless displacement of the handlebar along a pull line, but via an opposite winding and unwinding of a harness connected to the harness and a pull line on or from a Coil of handlebar unit.

A control system for kite-kite is known from DE 20 2005 000 708 Ul. This control system comprises two outer control lines and a main line and two outer deflection rollers, each connected to an associated control line. The main line is connected to a central pulley. About the pulleys mentioned runs a leash having sections with connection nodes. The control system is connected to the kite by attaching to the connection node the corresponding line sections on associated lines of the kite.

Another control system for a kite kite is known from US 7 686 254 B2. Also, this system includes pulleys, each having a pulley attached to an associated end of a common control rod or at an associated end of a respective respective pivotable control rod portion. From WO 01/52 961 AI a control rod system for a ite is known which has deflection rollers, which are respectively arranged at the ends of the control rod and over which the control lines to a central receiving roller, which is arranged in the center of the control rod extend.

An example of a system for attaching a kite line to a harness that provides automatic deployment for different selectable pull states is known from US 2007/0 1 14 333 AI.

SUMMARY OF THE INVENTION

The present invention has for its object to provide a device for adjusting a steering kite system that improves the handling of a kite system.

The device according to the invention is used to set a steering kite system comprising a screen, a handlebar and a harness. The fiction, contemporary device comprises a line system with two control lines, which are each connected at one end to a associated end of the handlebar, and at least one pull line for a train transmission between the screen and the harness. Furthermore, the device according to the invention comprises a receiving means for receiving and dispensing at least a part of the linen system, wherein by receiving or dispensing said part of the linen system in and out of the receiving means, the portions of the control lines between the handlebar and the umbrella together can be shortened or extended with the zugbelasteten section of the at least one tug line between the harness and the screen. The inventive device is characterized in that it comprises first deflection means for the control lines, wherein the first deflection means are attached to the screen and wherein the control lines are brought together via the first deflection means with the at least one pull line to be supplied to the receiving means together or to each other be coupled so that the tensioned sections of the control lines and the at least one tug line between the screen and the trapeze when mounting take or delivery of said part of the linen system in or out of the receiving means can be shortened or extended together.

In the described steering kite systems, the access latches of the control lines and the tug line - both on the side of the screen and on the side of the athlete - are necessarily spaced from each other to adjust by appropriate train, the relative orientation of the screen with respect to the athlete can. Due to the deflection by the first deflection means, however, it is not necessary in the invention to accommodate the control lines for an extension or for shortening in a place that is bound to the normal course of the control lines, in which the control lines between each end of the handlebar and the associated lateral end of the screen. Instead, the place of the linen pick-up and the linen delivery can be selected independently of the usual line guidance.

Due to the merging of the lines, it is further possible that the picking and delivery of the lines need not be made by a plurality of spaced receiving means, but that they can be made by a single common receiving means.

One possibility for a common extension or shortening using a single common receiving means is to merge the control lines and the tug line to the receiving means, there to receive the steering lines and the tug line directly with the receiving means and to deliver from this.

Another possibility is to bring the control lines and the tug line together and to couple them together, so that a tensile force can be transmitted between the lines. As a result, the control lines and the tow lines can be shortened or lengthened together without having to be picked up or released together into or out of the common receiving means. In a coupling, it is sufficient for a common shortening or lengthening to take up or give off a part of the linen system which is coupled to both the control lines and the tug line or which consists of one of these lines. This will be illustrated below with reference to an embodiment.

With the device according to the invention, the line system of a steering kite system can thus be lengthened and shortened together with only one common receiving means. the. The location where the receiving means is attached, is independent of the normal, ie designed for the purpose of controlling linen guide and can be chosen so that the athlete is not hindered. The present invention thus provides an additional possibility to collect the lines of a steering kite system and to clean them up quickly and easily.

The control lines can be merged with the tug line, for example, to an area that has a diameter of at most 40 cm. The diameter of this region is preferably at most 30 cm, particularly preferably at most 20 cm and in particular at most 15 cm. The spatial extent of the receiving means kami therefore be correspondingly low and may in particular be much smaller than the length of the handlebar. It should be noted that in the conventional steering kite system of Fig. 1 as well as that of US 2004 / 0065780A1 corresponds to the minimum distance of the control lines in the system, the length of the handlebar. Due to the deflection and merging of the control lines this minimum distance for the dimensioning of the receiving means or for the distance between receiving means is not a lower limit.

The coupling of the control lines with the tug can be done for example by connecting the lines. For example, the lines may first be manufactured individually and then joined together by knotting, braiding or linking. Alternatively, the lines can also be made as a common, branching leash.

In one embodiment, the device according to the invention further comprises a clamp or brake for fixing the line system guided by the clamp. The clamp kami prevents a part of the line system from being pulled through the clamp by the pull of the screen, which can prevent the tensioned part of the line system from being extended between the trapeze and the screen. Due to the fixation by the clamp, the pulling power of the umbrella can be transmitted to the athlete via the line system. Note that the "tensile member" of a line or a line system in the present disclosure always means that part where wind pressure would create a draft in the screen, regardless of whether the screen is exposed to wind pressure or not. Preferably, the line system can be at least partially pulled against the train of the screen by the clamp or brake, a zugbelasteter part of the linen system between the harness and the screen is shortened. This allows the athlete, for example, to reduce the distance to the glider while surfing by pulling a portion of the line system through the clamp. However, the line system is preferably still fixed against being pulled in the opposite direction. The length of the linen system drawn through the clamp can be picked up by the receiving means. In this way, the athlete can quickly and easily shorten the distance to the screen. This allows the steering kite system to be adapted to changing wind or space conditions during surfing and the umbrella can be landed easier and safer in a narrow bank area. In an advantageous development, the clamp or brake can be placed in a release state in which said fixation of the linen system is canceled. In this condition, part of the line system can be pulled by the pull of the screen through the clamp, thereby extending the tensile load of the line system between the harness and the screen. By determining how long it puts the brake in the release state, for example by applying pressure to the brake, the athlete can easily increase the distance to the screen in a controlled and stepless manner. This has the advantage that the athlete can easily and safely start the glider with a short distance to the glider, and then, on the water while surfing, can easily and safely increase the distance from the glider to a preferred length for surfing. Because the line system can be pulled through the clamp at least in sections in two directions by removing the fixation, the release state also offers advantages for a quick and uncomplicated erection and disassembly of the steering kite system.

The receiving means may be adapted, for example, to be worn on the body of the athlete or on the body of the trapezoidal wearer. For example, the receiving means may be worn on the back or on the side of the athlete in a pocket of the harness. As a result, the athlete is not hindered or disturbed when using the steering kite system.

In the aforementioned embodiments of the device according to the invention, the part of the linen system can be received or dispensed, for example, as a single line or as a linen bundle into or out of the receiving means. The inflow and outflow the linen system as a single strand to or from the receiving means allows a simple and compact design of the receiving means, simplifies handling and reduces obstruction of the athlete by a bulky or heavy recording medium.

In an advantageous embodiment, the device according to the invention further comprises a second deflection means. In this embodiment, the line system comprises a first pull line, which extends from the receiving means through the clamp or brake to the second deflecting means, which is deflected by the second deflection means in the direction of the trapezoid and the tensile strength connected or connectable thereto. It should be noted that the first pull cord for a high-tensile connection with the trapezoid does not have to be connected directly to the harness, but that it can also be fastened to another part, which in turn is connected to the harness in a tensile strength. The tension-resistant connection ensures that a train can be transmitted between the connected parts. In this embodiment, the line system further comprises at least two second pull lines, via which the second deflection means is connected in a tension-proof manner to the screen. The control lines are deflected by the first deflection means to the second deflection means and are each connected to one end of the first tug line. Because the control lines are connected to the first pull line, the tensioned line sections between the screen and the trapeze can be lengthened or shortened together by outputting or picking up the first pull line from or into the receiving means. However, the first tug line does not have to be received or delivered as a single line in or out of the receiving means, but can also be taken up or delivered together with the two associated control lines as a line bundle in or out of the receiving means. In the aforesaid embodiment, the first tug may have a smaller diameter on a first section between said tensile connection with the trapezoid and the connection with the control lines than on a second section passing between the connection with the control lines and the receiving means and / or that is in the shooting center. This makes it possible to keep a change in diameter at the transition from the first pull line to the line bundle from the first pull line and the two control lines low. This has advantages when said transition of the linen system is pulled through the clamp.

Preferably, the two control lines and the first section of the first pull line as a line bundle have a common diameter which is substantially equal to the diameter of the second section of the first tug line. As a result, it is possible for the diameter of the linen system to remain substantially unchanged during a transition from the individual first pull line to the line bundle. Thus, the diameter of the part of the line system that is pulled through the clamp is substantially constant and the clamp can be used indiscriminately or almost indiscriminately for a single line and a line bundle.

In the device according to the invention, the clamp can be integrated with a conventional quick-release in a common unit. In addition to the advantages of the invention, such a device also provides the usual safety features of most conventional kites. In addition, the athlete is not burdened by several different devices. In an alternative embodiment of the invention, the receiving means is not attached to the body of the athlete, but on the screen.

A development of this embodiment according to the invention comprises at least two pull lines. Alternatively, this embodiment may also comprise only one tug line, which, however, splits into at least two separate pull line sections. Furthermore, this embodiment comprises third deflection means in order to deflect the pull lines or the pull line sections on the screen. With the aid of the first deflection means and the third deflection means, both the control lines and the pull lines or the pull line sections can be deflected to the receiving means on the screen.

In the aforementioned embodiment, the said lines or line sections can be supplied to the receiving means from different directions and be received in the receiving means and be dispensed by the receiving means in different directions.

In one of the aforementioned alternative embodiments, the line system may further comprise an actuating line which extends from the receiving means to the trapezoid and over which the picking or dispensing of a part of the line system can be controlled. With the help of the actuating line thus the sections of the control lines between the handlebar and the screen can be shortened or extended together with the zugbelasteten portion of the at least one pull line between the harness and the screen. In any of the aforementioned embodiments, the receiving means may comprise an automatic line feed, in particular a roll with integrated strip spring. As a result, with a shortening by a certain length, a corresponding part of the linen system can be picked up directly and automatically by the receiving means, without requiring an operator or a manual Aufwickeins by the athlete.

In an advantageous embodiment, the linen system may be at least 80 percent of its length, preferably completely absorbed in the receiving means. This allows a particularly simple construction and dismantling or tidying the steering kite system, because the lines do not have to be awkwardly unbundled and designed and must not be wound onto a handlebar. The lines can be pulled out directly from the receiving means and only need to be pulled out of it until they can be connected to the screen. The line system can be quickly and easily stowed in the receiving means and there is protected from damage, for example, during transport.

One or more of the aforementioned embodiments may be used in common with a glider, handlebar, and harness of a conventional steering kite system. Because of this compatibility, the athlete can reuse parts of his existing equipment, so it is not necessary for the athlete, who wants to take advantage of the present invention, to purchase a completely new steering kite system.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Figures 2a and 2b show a device according to the invention according to a first embodiment, which comprises a receiving means 24, four first deflection means 26 and a line system. The receiving means 24 may be, for example, a take-up roll with integrated strip spring for the automatic collection of at least a part of the linen system. The first deflection means may be, for example, pulleys, loops, loops or guides, which are attached to the screen 12. The line system of the embodiment shown comprises two control lines 20, a first pull line 28, two second pull lines 30 and a lanyard section 31. The pull line section 31 may be part of the first pull line 28 as shown in FIG. Alternatively, the lanyard portion 31 may also be a leash that is different from the first lanyard 28 and that is provided in addition to the first lanyard 28. In addition, the embodiment of Figures 2a and 2b comprises a clamp or brake 32 and a second deflection means 34. The second deflection means 34 may be, for example, a deflection roller. As shown in FIG. 2 a, the receiving means 24 can be received on the back of the athlete, for example in a pocket on the harness 16.

In the following, the connections, the line guidance and the mode of operation of the line system of the embodiment of FIG. 2 will be described.

The two control lines 20 are connected at one end fixed to an associated end of the handlebar 14. Starting from the steering rod 14, the control lines 20 are respectively deflected via associated first deflection means 26 on the screen 12 and made of different Lent directions are supplied to the second deflection 34. Furthermore, the control lines 20 are merged with the first tug 28 and are connected in a node 36 with this. This compound is tensile and can be prepared for example by a linen linkage or a linen knot.

If the first tug line 28 and the lanyard section 31 are the same line, the first tug line 28 at one end of the lanyard section 31 is fixedly connected to the receiving means 24. Starting from this end, the first tug line 28 passes through the clamp 32 and is at a different end of the lanyard portion 31 in the clamp 32 tensile strength against a train of the screen 12 fixed or fixable.

If the first tug line 28 and the lanyard section 31 are different lines, the lanyard section 31 is fixedly connected to the receiving means 24 at one end and firmly connected to the clamp 32 at the other end. The first pull line 28 is in this case also connected at one end to the terminal 32.

Starting from the above-mentioned fixation in the clamp 32 (section 31 is part of the line 28) or from the end firmly connected to the clamp 32 (section 31 is no part of the line 28), the first pull line 28 extends from the direction of the trapezoid 16 the handlebar 14 to the second deflection means 34 and is deflected by this back to the harness 16. Behind the deflection, the first pull line 28 again passes through the handlebar 14 and is passed through the terminal 32. Subsequently, the first pull line 28 extends to and into the receiving means 24. Together with the second deflection means 34, the first pull line 28 forms a pulley.

The two second pull lines 30 are each fixedly connected at one end to the screen 12 and at its other end fixed to the second deflection means 34. As a result, the distance between the second deflection means 34 and the screen 12 when using the steering kite system is constant and not adjustable.

When using the steering kite system, most of the train from the glider 12 is transmitted to the athlete via the two second haul lines 30 and the first haul leash 28, and hardly, or only to a small extent, via the control lines 20.

With the help of the handlebar 14, the athlete can steer the screen 12 via the control lines 20 and change his angle of attack. When the athlete pulls the handlebar 14 horizontally toward the harness 16, the rear of the umbrella 12 lowers so that the umbrella 12 can absorb more wind (powering up). In this process, the angle of attack of the screen 12 changes and the tension through the screen 12 is increased. If, on the other hand, the athlete releases the handlebar 14 or moves it horizontally away from the harness 16, then the angle of attack of the umbrella 12 is changed due to the wind so that the umbrella 12 provides less resistance to the wind and the pull on the athlete decreases accordingly (depowering). , In order to steer the screen 12, the athlete pulls on the handlebar 14 only on one of the two control lines 20, wherein the train is transmitted to the corresponding side of the screen 12 and the screen 12 moves to this side.

Due to the rigidity of the wind-worn screen 12 and the relatively high tensile load on the pull lines 28, 30, the screen 12 is not or only slightly deformed when steering or powering. The line guide of the control lines 20, which are linked to the first tug line 28, does not change or not significantly. Thus, the steering kite system can be used with the inventively deflected line system as previous steering kite systems. In particular, the stability and control are not affected by the deflection.

To reduce the distance to the screen 12, the athlete may pull a portion of the first pull line 28 through the clamp 32. In this case, according to the principle of the pulley, the tensioned part of the first pull line 28 is shortened between the clamp 32 and the second deflection means 34. Because the pull lines 20 are connected or coupled to the first pull line 28, the tensioned sections of the control lines 20 are shortened the handlebar 14 and the screen 12 by the same length by which the distance between the terminal 32 and the second deflecting means 34 is shortened. This shortening length is equal to half the length of the line, which the athlete pulls through the clamp 32.

Due to an automatic line feed of the receiving means 24, the receiving means 24 when pulling a portion of the line system through the clamp 32 against the pulling force of the screen 12 automatically record a corresponding part of the line system, without the need for further action by the athlete would be required. By the clamp 32, the line system is fixed and secured against a pull of the shield 12, but can be pulled by the athlete against the pull of the shield 12 through the clamp 32. To increase the distance to the screen 12, the athlete can put the clamp 32 in a release state in which the fixation is canceled. Now, the screen 12 as long as the terminal 32 is in the release state pull a portion of the linen system through the terminal 32. In this case, the distance between the terminal 32 and the second deflection 34 increases together with the distance between the handlebar 14 and the screen 12. As soon as the athlete cancels the release state of the terminal 32, the line system is fixed again and prevents further extension. It should be noted that the first pull line 28 can also be guided together with the two control lines 20 as a linen bundle through the clamp 32 and fixed with this. The linen bundle can also be taken up or released into or out of the receiving means 24. As with a conventional steering kite system, so-called trimming can also be carried out with the aid of the device according to the invention, in which the tensile-stressed sections of the hauling line 28 and the control lines 20 between the trapezoid 16 and the screen 12 are not lengthened or shortened together by the same length, but their aspect ratio is changed. For this, the clamp 32 of the device according to the invention may include a trim means 38, with which the line position at which the first pull line 28 is fixed in the clamp 32 or fixedly connected to the clamp 32 can be changed. This change is preferably not made during operation of the steering kite system on the water, but before on land.

For example, in order to trim the steering kite system of FIG. 2b such that the tensile portion of the hauling line 28 is extended without elongating the tensioned portions of the control lines 20 between the handlebar 14 and the shield 12, the portions of the first hauling line 28 may extend between the attachment and the fixed connection at the trim means 38 and the second deflection means 34 and between the other fixation in the clamp 32 and the second deflection means 34 are extended by the same length. Overall, thereby the zugbelastete section of the tug line 28 between the screen 12 and the harness 16 is extended. The connection point 36, however, does not change its position or distance with respect to the second deflection means 34, so that the length of the tensioned sections of the control lines 20 is not changed. Accordingly, the aspect ratio during trimming can also be changed in the other direction. As shown in FIG. 2b, the first pull line 28 in front of and behind the trim means 38 may include optional knots or beads which prevent the line from being pulled through as far as desired secure by the trim means 38 and whose distance dictates or limits the trim area.

The following describes how the device according to the invention can be used together with a two-stage safety system.

The clamp 32 shown in Figures 2a and 2b is integrated with a quick-release system in a common unit comprising a loop 40 (so-called "chicken loop") and a securing extension 42. To between the first pull line 28 and the trapeze 16 to make a tension-proof connection by which the train can be transferred from the umbrella 12 to the athlete, the loop 40 is hooked into a hook on the harness 16. The securing extension 42 is pushed outside the hinged loop 40 by the hook of the harness 16 prevent inadvertent unhooking of the loop 40. Figures 3a to 3d illustrate how a stunt kite system that can be adjusted with the embodiment of Figure 2 according to the invention can be separated from the athlete in an emergency the athlete solve the train connection between the screen 12 and the harness 16, for example, if he is in control of the screen 12th loses and to prevent being swept away by this.

In FIG. 3 a, the athlete has activated the quick-release mechanism and thus loosened the loop 40 at one end from the clamp 32, so that the tension transmission from the shield 12 to the trapezoid 16 is interrupted and the loop 40 is completely detached from the trapezoid 16. After the triggering of this first level of security, the athlete no longer opposes the visor to the visor, but is still connected to the parachute 12 via the lanyard portion 31. The unit of shield 12, handlebar 14 and clamp 32 may be removed from the sport 1 (Figure 3b). Because no control on the screen 12 acts on the control lines 20, the orientation or the angle of attack of the screen 12 changes such that the rear part of the screen 12 folds upwards and the screen 12 offers less resistance to the wind (FIG. 3c). , The umbrella 12 usually tilts laterally out of the wind window when the first safety level is triggered or falls. Because the athlete is still connected to the glider 12 via the lanyard portion 31, the athlete is prevented from losing the glider 12. Should the umbrella 12 not fall despite the first safety level triggered and continue to be pulled away by the athlete, for example from a ship or other object, then the second safety level is triggered by the lanyard portion 31 pulling off the receiving means 24 from the harness 16 and the shield 12 completely clearing away from the harness Athlete is separated (Figure 3 d). Accordingly, the pull lines 28, 30 and the lanyard portion 31 of the device according to the invention can also take over the function of a safety leash 22 known from the prior art. Figures 4a to 4g show the structure and operation of a clamp 32 according to the invention with a quick release mechanism for the previously described embodiment of the invention of Figures 2 and 3.

Figures 4a to 4c show schematically different states of actuation of the terminal 32 through which a part of the linen system is guided. In Figure 4a, the line system or the first pull line 28 is fixed and can not be pulled by the train of the screen 12 through the terminal 32 (in Figure 4a up). Pulling in the opposite direction of pull of the screen 12, which is shown in Figure 4a by a downward arrow, however, is possible.

In Figure 4b, the terminal 32 is in a release state in which the line system can be pulled by the train of the screen 12 through the terminal 32. The clamp 32 can be placed in the release state of Figure 2b by the sportsman presses from the direction shown by the horizontal arrow against the terminal 32 and operated with it. In the release state, the pulling through of the linen system by the pull of the screen 12 does not necessarily have to be carried out without resistance, but it can also take place against a resistance which the athlete can also control by means of the actuating pressure, for example. For example, as shown in FIG. 4b, it can be provided that by increasing the actuation pressure, the athlete can increase the braking force acting on the line system, so that he can regulate whether and how fast the line system is released. As a result, the distance to the screen 12 can be easily controlled and continuously extended. If the athlete releases the clamp 32 during the extension process, then the clamp 32 system and line system will recover by a self-reinforcing clamping action (as shown in Figure 4a), so that involuntary leashing out of the line system can be prevented. In FIG. 4c, the release state is fixed with the aid of a fixing means 44, so that the line system is free and can be pulled through the clamp 32 in both directions, for example for the purpose of clearing or building, without the athlete having to maintain a certain actuating pressure ,

Figures 4d and 4e show construction drawings of an embodiment of the clamp 32 according to the invention, which is shown in Figure 4f without a shell and in Figure 4g with a sheath 45. Figures 4d and 4f show a lever 46, which is in normal operation within the shell 45. By pushing the sleeve 45 away from the body, the athlete releases the lever 46 so that it can fold away laterally. As a result, the connection is released at the corresponding end of the loop 40 and triggered the first level of security. FIG. 4g further shows a trim means 38 for carrying out the previously described trimming. The trim means 38 shown in FIG. 4g is a cable clamp with which the first pull line 28 can be fixed at different line positions or firmly connected to the clamp 32. A separate trim system, as used in conventional kite systems, is therefore not necessary.

Figures 5a, 5b and 5c respectively show a rolled-up state (Figure 5a), a state with short line sections between the trapezoid 16 and the screen 12 (Figure 5b) and a condition in which the adjustable line sections have a maximum length (Fig. 5c). In order to clean up the device according to the invention with the steering kite system, as shown in Figure 5a, the control lines 20 are separated in respective areas between the handlebar 14 and the lateral ends of the screen 12 or untied from the respective end of the handlebar 14. Nodes or beads may be provided on the uncoupled ends of the screen-side control line sections, which prevent the ends from being pulled by the first deflection means 26 on the screen 12. A further separation of the control lines 20 may be provided in each case in a section which extends from the link 36 with the first pull line 28 to the screen 12, when the separate from the handlebar 14 end of the control line 20 is pulled up to the screen 12. Furthermore, the second deflection means 34 can be separated or untied by the second pull lines 30. Accordingly, after untying, a portion of the linen system may remain on the screen 12 and be stowed therewith. In the state of Figure 5 a, the control lines 20 and the second deflection means 34. As described above, separated, so that the screen 12 with the separated parts of the control lines 20 and the second pull lines 30 completely from the terminal 32, the handlebar 14 and the second deflecting means 34 is separated. The first pull line 28 can be pulled so far through the terminal 32 until the second deflection means 34 on the handlebar 14 and until the handlebar 14 abut the terminal 32. In this case, the majority of the linen system can be stowed in the receiving means 24. The device according to the invention thus allows a quick and easy tidying of the steering kite system and avoids a complicated winding of the lines 20, 28 by hand. Furthermore, there is no danger that the lines 20, 28 get tangled up during rolling up or unrolling.

Figure 6 shows an inventive device according to a second embodiment with a receiving means 48, which is not provided as the receiving means 24 of the embodiment described above for attachment to the harness 16, but is attached to the screen 12. The second embodiment of Figure 6 comprises two first deflection means 26 and two third deflection means 50. The third deflection means 50 are fixed to the screen 12 and serve to deflect the pull cord 52. Unlike the first embodiment, the pull cord 52 of the second embodiment is in a trapezoidal section from a single line, which splits in a connection point in the direction of the screen 12 into two separate lines or line sections, which are respectively fed to the receiving means 48 via an associated third deflection means 50. Likewise, the control lines 20 are supplied by their associated first deflection means 26 to the common receiving means 48.

The second embodiment of Figure 6 further comprises an actuating line 54 which is connected to the receiving means 48 and extends to the trapezoid 16. The actuating line 54 may be connected via a roller (not shown) with the athlete, in which it can be accommodated and which can be attached to the harness 16, for example. With the aid of the actuating line 54, the athlete can control an extension and a shortening of the tensioned line sections between the trapezoid 16 and the screen 12, as will be explained below with reference to FIGS. 6 and 7.

FIG. 7 shows the receiving means 48 from two mutually perpendicular sectional views. The receiving means 48 consists of a roller, wherein on each side of the roller, the control lines 20 can be picked up and delivered and taken on an opposite side of the tug 52 or respective sections of her and can be delivered. It can be seen from FIG. 6 that the separate pull line sections 52 and the control lines 20 are fed to the receiving means 48 from different directions. The receiving means 48 comprises a band spring, which is adapted to retract the control lines 20 and the pull line 52 against a certain maximum counter-pull in the receiving means 48. The seat means 48 further comprises a cable brake with a brake cable 56. If the athlete does not exert a pull over the actuating line 54, the cable brake is active and prevents pulling of the screen 12, the control lines 20 and the pull line 52 from the receiving means 48 can. By a slight pull on the actuating line 54, the athlete can release the rope brake, so that the train of the screen 12 against the force of the band spring a part of the control lines 20 and the pull line 52 can pull out of the receiving means 48 as long as the rope brake released is. As soon as the athlete gives way to the actuating line 54 and is no longer under tension, the rope brake engages again and further extension is prevented. To reduce the distance from the athlete to the screen 12, the athlete pulls on the actuating line 54 more so that the angle of attack of the screen 12 is changed and the screen 12 is removed from the wind. Then the train of the screen 12 is reduced over the lines or he leaves completely, so that a part of the control lines 20 and the tug 52 are retracted by the tensile force of the band spring in the receiving means 48.

The fact that the actuating line 54 pulls down the front side of the screen 12, it can also serve as a safety line, as described in connection with the first embodiment. When the umbrella 12 has landed, the control lines 20 on the handlebar 14 and the pull line 52 can be clipped on the trapezoid side. Subsequently, the entire line system 20, 52 are received in the receiving means 48 and the screen including receiving means 48 are wrapped. It should be noted that the embodiments described above are to be considered as purely exemplary and the invention is not restrictive and that the features described may be of importance in any combination.
