Abstract

Disclosed is a device for kite surfing with pneumatically inflated, stiffened steerable kites. Kite surfing is a water sport which is comparable to windsurfing; however, a steerable kite is used as a sail. The safety systems of conventional steerable 4-line kites are provided with serious flaws while obstructing the athlete and hampering the further development of said sport. The aim of the invention is to overcome said flaws by means of a device that provides optimum comfort as well as a more basic, less expensive version thereof. Said aim is achieved by mounting a quick release shackle (29, 26, 27), to which a control device (30a/30b, 38, 9, 39, 10, 40) is attached, on the hook plate (17) of the surfer's trapezoid-type pants. Said control device is designed such that intertwinings between the kite lines and the safety leash, which are caused by rotations of the kite or the athlete, can be manually or automatically untwisted also during surfing. The safety leash (4, 7b, 16) prevents the kite from being lost without obstructing the athlete during rotational jumps while allowing for an immediate relaunch following an emergency water landing of the kite after actuating the primary quick release shackle (29) without having to deal with tangled lines and without having to do a lot of manipulations in the water.

Description

DESCRIPTION

Improved safety system for 4 line stunt kites; Control device for the automatic but also manual release of tangles of the kite lines with the safety line; Quick release stationary.

This system refers to inflatable, pneumatically shaped and stiffened stunt kites (also known internationally as Inflatable or Tube Kite) for locomotion on water (kitesurfing)

General state of the art

Kite surfing with stunt kites Stunt kites, also known internationally as kites (plural: kites) generate propulsion for new sports such as kite surfing on water (also known as kitesurfing), comparable to sailing sailboats. Similar to today's windsurfing or snowboarding or wakeboarding, the driver is connected to a specially shaped board by means of foot straps or bindings. The buoyancy in the water is generated almost exclusively dynamically by the driving speed, comparable to water skiing. The stunt kite is connected to hold and steer on the one hand on the stunt kite and on the other hand on a control rod by means of high-strength lines. To relieve the very high holding forces, the drivers wear so-called trapeze belts on their bodies - or trousers that are provided with a hook plate, and thus hang in a loop called a trapeze rope, which is attached to the control rod. This allows the driver to use his weight and body as a lever to absorb the high holding forces. The driver only has comparatively small steering control forces. In an emergency, the driver unhooks and may let go of the control rod. In order not to lose the stunt kite in such an emergency, various safety line systems have been developed. These systems are based on the fact that one or more of the tether lines or control lines are firmly connected to the driver via an additional so-called safety line and that the kite can blow out largely without force when the control rod is released. The principle of restarting the stunt kite from the water (described internationally as a "relaunch") by the driver alone and without outside help is possible.

PRIOR ART Inflatable, pneumatically shaped and stiffened stunt kites with a four-line control. These stunt kites are constructed in such a way that at least the leading leading edge is provided with an integrated inflatable bead. Further inflatable beads in an approximately rectangular arrangement to the leading leading edge (wing nose) are usually used to stiffen the structure in the other direction. Replacement or additional stiffening by means of sail battens embedded in pockets are also in use today. In use, the beads are inflated and closed with a stopper. Due to the cut of the kite cloth and the pneumatic beads, the inflated kite essentially takes the form of an inverted U or a sickle when viewed from the front. The control or tether lines are attached to the U 's ears.

State of the art four-line control The most important reason for the four line technology is the possibility of being able to adjust the kite to a very wide range of wind speeds by arbitrarily adjusting the angle of attack of the kite, both before starting the journey and during the journey the driver can be changed himself. This is usually done via part 10 (see FIG. 3 to 5), a commercially available webbing belt (GBT), where L 2 denotes the adjustment path, which is usually around 200 mm. So z. B. Kites in two line technology can only be safely controlled over a narrow range of wind speeds. Above and below, other kite sizes would have to be selected before starting the journey. The prior art of the four-line control and usual arrangement of the safety line is shown in FIG. 1 shown schematically. FIG. 2 schematically shows a 4-line kite with an additional center line. FIG. 1 and 2 show the kite in flight at the zenith at the edge of the wind window, with kite lines and control rod in flight position, without a driver. Explanation of symbols FIG. 1 and 2 Note: ln the headings of all drawing sheets means: DL = kite lines, parts 2, 3, 4, 5 SL = safety leash, parts 6, 7, 16 QR = primary quick release shackle, parts 26, 27, 28 1 stunt kite 2 left tether (front line), high-strength kite line 3 right tether (front line), high-strength kite line 4 left control line ackack line), high-strength kite line 5 right control line ackack line), high-strength kite line 6 conventional safety line (safety leash) 7 middle line (high-strength Kite line), leads to a fastening point in the middle of the wing nose of kite of the latest design with dual function as a safety line (safety leash) 15 usually a connection of the safety line z. B. using a webbing with Velcro on the wrist or on the driver's harness A significant advantage of the four lines technology is that with a corresponding design of the attachment of the tether to the handlebar on the so-called De-Power loop by sealing and tightening the handlebar sensitive adjustments of Power of the kite are possible in gusty winds. See FIG. 3. L 2 is the stroke distance for sealing and lubrication, which is usually around 150 - 300 mm. This process can be compared to sealing and securing the mainsheet when sailing or the boom when windsurfing.

State of the art of safety devices kites of the above. With an appropriate flow, types can develop enormous forces and lead to serious injuries or death of the driver. This is particularly the case if the driver has lost control and is inadvertently pulled towards a rigid obstacle. While when windsurfing the driver's involuntary departure, the sail comes to rest on the water surface and thus loses all power, when kite surfing the kite is still in the air and fully under power when the driver involuntarily leaves. A typical commercially available safety device consists of parts 6, a safety line and 15, a belt strap with a Velcro fastener for attachment to the driver's wrist. The safety line 6 is connected on the one hand to the kite line 3 and on the other hand to the belt with Velcro fastener 15. The way it works is that the driver releases the control rod in an emergency. Since the kite is connected to his wrist via the tether 3, the kite can fly like a flag in the wind and thereby lose almost all power. In theory, the driver can then use appropriate techniques to restart the landed kite.

Disadvantages and serious safety deficiencies in today's inflatable stunt kites with four-line control. There are two complexes of problems here: an emergency release device, also called a quick release, for emergencies, in order to be able to suddenly separate from the kite, and the safety line, which is intended to prevent the loss of the kite and subsequent distress at sea. Emergency release device / quick release The sole purpose of the emergency release device is to completely and suddenly separate the driver from the kite in an emergency if he is hooked in with the trapezoidal hook, Figure 8, Part 21, in the de-power loop, Part 13, Figure 3 to 5, drives. In emergencies, the driver may not have enough power to unhook, especially if he is involuntarily dragged under water by the kite or is dazed by the impact on the water. In addition, the regular unhooking from the de - power loop is an extreme effort, because by pushing the control rod down to get out of the loop, the kite is set to maximum performance. In the suspended state, letting go of the control rod to free yourself from the drag of the kite is not the solution. The tractive force is somewhat less because the control rod to the end point of the stroke L 1, FIG. 3 to 5, but it still hangs and is connected to the kite.

Problem 1 with the safety line, when actuated in an emergency by releasing the control rod, driver not hooked into the harness: previously known systems do not work sufficiently reliably. Because of the four lines, especially if the lines are twisted by the kite turning or by the driver's rotation, the released control rod can get tangled like in a net. It has often been observed that in such cases the kite, when fully inflated, stabilizes in one position and pulls the now uncontrolled driver attached to the safety line with full force. The actuation of an existing emergency tear system can defuse the position of the driver, but inevitably leads to the loss of the kite. Even after regular operation, i.e. letting go of the control rod, often linen salad, which makes a controlled relaunch impossible. Almost unavoidable when there is a lot of wind because the kite whips or rotates uncontrollably when it comes down. The reason for this is on the one hand the long way the released control rod has to travel until the kite is fully blown out. and on the other hand that the control rod ends up undefined in the middle of the control and tether lines after being released.

Problem 2 with the safety line while driving, the driver is suspended in the harness: top performers manage twisted steering lines, caused by the kite turning or the driver's rotational jumps while turning out while driving. This is achieved by an equal number of rotations in the opposite direction with subsequent rotation jumps. Nevertheless, even such drivers have to untwist their lines conventionally after a possibly inadvertent watering before a relaunch of the kite, because twisted control and tether lines make the start considerably difficult or impossible due to the high friction. If the safety line is attached to the wrist, the driver must unhook from the trapeze during the watering, rotate the control rod and in doing so guide the safety line around the control rod at the rear. An overall inappropriately cumbersome process. When the safety line is passed through the de-power loop and attached to the hook plate of the trapezoidal belt or on the body, and using the existing de-power loop, the untwisting is much easier. Only the control rod with the de-power loop is rotated in the trapeze. While this eliminates the twisting of the control lines, as a consequence, behind the control rod towards the driver, the safety line twists with the pull rope of the de - power loop. Even at little more than three to four turns, these lines can pinch so that the kite can no longer blow out sufficiently in an emergency when the control rod is released and consequently puts the driver in need. Problem 3, driving without a safety line, driver hung in the harness: Very good and sporty drivers drive without any safety line for the reasons mentioned above. This makes it possible, even when the driver is hooked into the de - power loop, to make the handlebar rotate with a swing during a jump and to let it rotate freehand until the control lines are untwisted. However, since the driver, including the control rod and lines, is lost to the driver when the handlebar is released in an emergency, the rescue from distress and salvage of the lost stunt kite must be secured in the appropriate areas beforehand.

Main problem:

Conflict of security systems emergency release device vs. Safety Line Off Above Connections make it clear that a quick release is just as important as the safety line. However, since the safety line can twist and get tangled or the system fails as such (see paragraph: Problem 1 with the safety line ff), it represents such a danger that many drivers, due to the lack of alternatives, tend to lose the kite and the variant prefer swimming home. Emergency release devices or quick releases, as are customary in the trade today or assembled individually by the drivers themselves, often solve only one problem, namely to separate the kite from the driver. However, a kite, separated from the driver and therefore whirled by the wind, including lines and control rod, can pose a fatal hazard to third parties, like many accidents, including a world-class fatal accident. Kite surfer, have shown lately.

Problems with the emergency triggers of commercial and individual solutions One of the many problems with this is that the quick release, regardless of the type, often does not open as desired under load, even if the emergency operation could take place without hindrance. This always occurs when the current tensile load is applied to the quick release at the wrong or unsuitable angle. This is determined by the type of attachment to the hook plate or hook. Others require the athlete to perform a powerful push with both hands in an emergency, which is certainly not ideal for normal mortals. Another problem is that the trigger pivots and / or rotates around its axis depending on the pulling direction of the kite, these elements not being rotationally symmetrical. Because the athlete has to guess or feel them in an emergency, the reaction time cannot be as fast as with a trigger that is always located in the same position in the same position, unchanged relative to his body.

INVENTION TASK:

The object of the invention described below is to eliminate the aforementioned deficiencies by means of an optimal device with the highest level of comfort, but also with a device which is slimmed down in terms of cost and comfort, or to bring about considerable improvements in handling and safety. The invention relates both to the four-liner mentioned - with a classic safety line as well as to the latest four-liner with additional center line.

In addition, a device is to be shown which does not need a conventional safety line but nevertheless fulfills the desired function. This device does not entangle and bind the kite lines by means of a safety line when the driver or kite rotates. All of the solutions shown below are compatible with a stationary emergency release. Here, stationary means: it is arranged in a fixed position relative to the driver's body and the trigger does not pivot, nor does it rotate. The following descriptions contain the version optimized for the system presented.

INVENTION SOLUTION:

The solution according to the invention has four main directions: a) To create an emergency release in the area of the connection via the trapeze of the driver, which triggers at all conceivable pull angles and is arranged in such a way that the release mechanism can also be found quickly and easily in panic , b) to supply a control device with a special arrangement of the safety line, where the twisting of the safety line with the rope of the de-power loop, even with a very large number of jump rotations of the driver in any direction of rotation or rollover of the kite, is accepted and without significant effort or without the driver's intervention, even while driving, can be undone so that the driver is not hindered or endangered. In addition, this device should also enable the tether lines to be turned back after jump rotations (which has not been possible up to now even in systems without a safety line) and thus to absolutely neutralize any twisting of all lines. c) Furthermore, both the novel control rod in combination with the emergency release according to the invention and the special arrangement of the safety line according to the invention in the overall system should ensure that the kite is not lost in the event of an emergency release or endangers third parties, but allows the driver to relaunch as quickly as possible , The rapid relaunch can only take place if neither the kite nor the lines tangle tangibly after the emergency release. d) the use of an asymmetrically attached safety line, as part 6 in FIG. 1 and 3 and to use a mini safety line instead, since the usual arrangement with jump rotations of the driver leads to a tethering of the flying lines, with correspondingly high, friction-related control forces. Such systems have already been introduced in the kite scene. But you all suffer from a lack of everyday suitability. This way, trapeze ropes and the mini safety line rub through very quickly (in just a few hours). Replacing the trapezoidal stamps costs little money and time. In contrast, the mini safety line in such models is a very expensive special kite line. Delayed replacement can also significantly endanger the driver's safety. There is a clear need to improve this.

The solution according to the invention according to points a), b), c) and d) is shown in modular form in the following description with detailed drawings. The modules can be freely selected and combined according to requirements. The options are as follows:

I. Type of safety line. This option is determined by the individually available kite and line set or according to your preference: • Standard kite with conventional safety line as an extra line with stopper at the end, connected to a holding line at a certain distance from the control rod (see FIG. 3) • Kite with an additional attachment point in the middle of the wing nose and an extra line, so-called 5th line, there (see FIG. 4) Standard kite, by means of the devices described here, converted into an arrangement apparently without a safety line, but with a mini safety line (see explanations for and overview of FIG. 5)

II. Wear-free or maintenance-intensive depower cables / safety leash • for the wear-free version, see explanations for FIG. 8b; ff • for the more maintenance-intensive version see explanations for FIG. 8a; ff

III. Autorotation or manual turning back of the turner in leash & lines • Autorotation means here that the athlete only rotates the control rod to turn back the steering lines after rotations; the twisting of depower cables, safety leash and tether lines that usually occur are automatically neutralized, even while driving, without the driver's intervention. The centerpiece here is a watertight encapsulated swivel with a ball-bearing hollow shaft. See overview FIG. 8a and 8b and details in FIG. 9b and 12. • Manual turning back here means that the athlete rotates the control rod to turn back the steering lines after rotations; he then has to manually remove the twisting of depower cables, safety leash and tether lines that occurs, or accept it first. The resulting twists can also be neutralized while driving by briefly releasing pressure from the kite and grasping the vertebra with a free hand and turning it back. The centerpiece here is a swivel with a hollow shaft with a plain bearing. See overview FIG. 8a and 8b and details in FIG. 9a.

Solution to a) The solution to a) is achieved with regard to the demand for a trigger mechanism which can be found very quickly even in panic situations and which can be actuated particularly simply and safely, in that the de-power loop 30, 30a is inserted into the eye of the primary quick release shackle 26 and locked. The novel (the factory release rope must be removed beforehand), extremely smooth and stationary release mechanism (shown in an arrangement for right-handers), which only works under load, is activated by a pulling movement (down, or up, or to the right (to the left or forward, an unnatural pushing movement would be actuated for the right-hander) on the hose 27. When the primary quick-release shackle 29 is actuated via parts 26, 27, the depower ring 30, 30a is released and the kite blows out, but remains on the safety line 6, 7b, 16, secondary quick-release shackle 32 and the hook plate 17. The primary quick-release shackle 29 itself is latched into the secondary quick-release shackle 22. The secondary quick-release shackle 22 is in turn welded onto the hook 21 in such a way that it is optimally aligned is, on the one hand, the primary quick release shackle 26, in the open n Clear condition to release and on the other hand to form a favorable angle for attaching the release mechanism, part 23. This arrangement is and remains and always in the same position and can be easily internalized by the driver. The trigger mechanism 23 is carried out by a plastic ball 24 and secured there with a stop knot 25. The trigger mechanism of the secondary quick release shackle is sufficiently smooth even under load, so that a pulling movement on the ball can actuate the emergency release. The actuation of the secondary quick release shackle 22 is only intended for the most extreme emergency, since this completely releases the kite. The second aspect, securing the emergency release under all possible pull angles, is achieved by two measures. On the one hand, the primary quick-release shackle 26 is latched in the secondary quick-release shackle 22 in a freely movable manner and this is open the hook 21 is pivotally arranged on the hook plate 17, so that the forces of the kite, regardless of whether the kite flies above or below, are always introduced into the quick release shackle in the ideal direction. On the other hand, the depower loop 30, 30a is made of round stainless steel material, so that the tendency of conventional plastic loops to get caught on the shackle exits in the horizontal plane when force is applied obliquely does not exist here.

In addition to the requirements mentioned, the retention of the hook 21 and its function left the option open for the driver to hang the hook in the optional standard trapezoidal rope 11 (FIG. 3, 4, 5). Stops and cams in the area of the swiveling hook have been deliberately avoided in order to avoid injuries to the hands.

Mode of operation of the device according to solution to a):

When the emergency release 29 is actuated via parts 26, 27, the kite pulls the control rod 9 away from the driver. It slides guided on the safety line 6, 7 along or in the case of the arrangement according to FIG. 5 on the safety line 16 and further on the holding line 2b until it runs against the stop ball 8 and stops. For the arrangement of the safety line in the respective system, see FIG. 3, 4 and 5.

The stop ball 8 is secured with stop knots on the lines or special, so-called knotless stop balls are used. The respective distance to the stop ball, L 3, L 4, is calculated so that the rest of the kite lines become so loose by rushing out the control rod that the kite can blow out almost without power. By connecting the other At the end of the safety line 6, 7 and 16 on the driver's hook plate, the now weak kite remains tied to the driver. See also FIG. 13, 14 and 15

Solution to b) In order to understand the solution, the problem must first be detailed: Inevitably, when turning the control rod 9 back after rotation jumps, only the control lines 4 and 5 are released. The tether lines 2 and 3 remain twisted. This also applies if no safety line is used. The twisting of the tether lines 2 and 3 remains without significant consequences in this arrangement. As can be seen from many design proposals from the kite scene, it is obviously obvious to simply lead the safety line through the central hole in the control rod like the de-power lines, believing that this would solve the twisting problem. On the contrary, now when the control rod is turned back, the safety line even wraps around the TaljelO and hinders its function depending on the number of twists. This is because not only the control rod 9 rotates in its axis of rotation during jump rotations, but also the power loop 30a, 30b, the power tow 38, the adjusting tether 10 and the two tether lines 2 and 3, since the driver during the jump is attached and at the same time holds the control rod. When turning the control rod back, however, only the two control lines 4 and 5 are turned free. The solution to b) is achieved on the one hand by arranging the safety line centrally, so. In the axis of rotation and rotating all other lines around this axis of rotation. To achieve this goal, the free end of the safety line or its extended end 6, 7b, 16 is as shown in FIG. 9a and 9b, inserted through the hollow shaft of the vertebrae 46 and 55 and in the area of the belt strap 10 by means of an eyelet 40 fastened there in the rear belt strap, and subsequently, see FIG. 8a, through the central bore in the control rod 9 itself, or through the guide eyelet 42 and protective hose 38, see FIG. 8b, and connected to a stainless steel ring 33 and in the secondary Wichard Quickrelease shackle 32, as shown in FIG. 7 shown, latched. The entire arrangement just described is shown as an overview in FIG. 6a and FIG. 6b shown. The solution to b) is achieved, on the other hand, in that the kite side is separated in rotation from the control rod side by means of a vortex in between. Thus, all kite lines are on the upper part of the vertebra and the de-power lines on the lower. Since, according to the teaching of the invention, the safety line is now guided through a hollow shaft in the vertebra 46, 55, this system could avoid any twisting of the lines when the control rod is turned back. This would be the case if the parts which are held on the upper part of the vertebra (the depower loop 30a, 30b, the de-power tow 38, the adjusting tether 10 and the two retaining lines 2 and 3) are connected to the control rod via drivers. Such an arrangement with driver ropes is shown in FIG: 12. However, a vortex with ball bearings is required, shown in FIG. 9b in order to prevent that when the control rod 9 is turned back under load, not only the dog rope winds around the vertebra instead of turning the vertebra back because its resistance to rotation is too high. Mode of operation of the device according to solution to b: When using the vortex with slide bearing, as shown in FIG. 9a, after the control rod has been turned back, the driver can manually remove or initially accept the twisting of depower cables, safety leash and tether lines that usually occurs. The resulting twists can also be neutralized while driving by briefly releasing pressure from the kite and lifting the vertebrae with a free hand and turning them back. See overview FIG. 8a and 8b and details in FIG. 9a When using the ball-bearing vertebra as in FIG. As shown in FIG. 9b, the athlete need only let the control rod spin to turn back the control lines after rotations; the twisting of depower tow, safety leash and tether lines that usually occur are automatically neutralized, even while driving, without the driver's intervention. See overview FIG. 8a and 8b and details in FIG. 9b and 12.

For details of the correspondingly modified control rod with additional devices according to the teaching of the invention, see overview FIG.6a, ff and FIG. 6b, ff.

In FIG. 8a shows an arrangement of elements for a central passage of depower tow 38 and safety line 6, 7b through the control rod 9. Since the control rod 9 is moved on these ropes during flight operation, they wear out with use. In order to minimize wear, these ropes must either have a non-sticky, slippery substance in the wear zone, e.g. B. impregnation with a hot wax mixture or with a plastic coating. The balls 36 and washers 37 made of plastic have a pressure distribution function and ensure a clean entry and exit of the ropes with strong steering deflections of the control rod 9.

In FIG. 8b shows an arrangement of elements for a central passage of the power tow 38 and the safety line 6, 7b through the control rod 9. In order to avoid wear on the ropes carried out, they are passed through a protective tube 41. However, the protective hose must have a very slippery surface and be flexible in order not to hinder the steering. On the other hand, the hose must be kink-resistant and have a large enough internal width to accommodate the sufficiently large ropes and to let the safety line slide through. All of these requirements lead to an outer hose diameter which has too little play in the central bore of the control rod for practical purposes. A larger hole would weaken the rod too much. Therefore, a clamp device with a corresponding larger eyelet 41 is attached to the center of the control rod for the passage of the protective tube 41. The balls 40 and washers 37 made of plastic have a pressure distribution function and ensure a clean entry and exit of the ropes with strong steering deflections of the control rod 9. Furthermore, they fix the protective hose 41. An adjusting device, parts 43, 44, 45 attached which can be retightened to compensate for the expansion of the pad 38.

Solution to c) The requirement that the kite is not lost or endanger third parties in the event of an emergency release is achieved, as already described above under solution to a), in that the free end of the safety line is attached to the hook plate and thus with the driver is anchored. The secondary emergency release mechanism does not contradict these requirements, since it would only be used as the driver's last resort when all of his other rescue options have failed. How the demand for a simple relaunch option without significant linen salad after the emergency release is achieved according to the invention is described below. Device according to the teaching of the invention: The requirement for a simple relaunch option without significant linen salad after the emergency release is achieved by the central arrangement of the safety line of whatever system (see FIGS. 3, 4 and 5) and its central threading through the control rod or Attachments to it. For the connection of standard 4-line stunt kites, the fairly central connection of the safety line 6 to one of the tether lines 3, instead of to one of the outer control lines 4, 5, should also be mentioned here. See drawing FIG. 3. For details of the connection to a 4-line stunt kite with additional center line 7, see FIG. 4. For details of the connection of a standard 4-line stunt kite with a mini safety line, see FIG. 5. Note: Optional trapezoidal rope 11 in other relevant FIG. not shown. In addition, the part numbers refer to components which are used in accordance with the teaching of the invention and not to the known prior art.

Mode of operation of a conventional device according to the prior art:

To the effect and degree of improvement of the above. To be able to recognize the innovation described, the known mode of action should first be understood.

FIG. 13 shows a schematic representation of a blowing, landing std. 4-line stunt kite with conventional safety line 6, the end of the safety line 6, z. B. is attached to the wrist of the driver by means of the Velcro strap 15 (not shown).

Explanation of symbols for FIG. 13 1 stunt kite 5 right control line, high-strength kite line 4 left control line, high-strength kite line 3 right tether, high-strength kite line 2 left tether, high-strength kite line 6 safety line 8 stopper ball 9 control rod 15 webbing with Velcro fastener for attachment to the wrist of the driver L 3 minimum distance of the stopper ball L5 span of the kite in the deployed, not inflated state W 1 wind direction

As the illustration FIG. 13 shows, the control rod 9, after being released or after actuation of the emergency release, since it is not being guided, has landed undefined in the middle of the kite lines, far away from the driver. A waving kite that lashes with a lot of wind can turn the free control rod along with other kite lines and thus additionally ensures linen salad, which in practice can only be avoided by luck.

Mode of operation of the device according to the invention:

When the emergency release 29 is actuated via parts 26, 27, the kite pulls the control rod 9 away from the driver. It slides along the safety line 6 or 7, or in

In the case of the arrangement according to FIG. 5 on the safety line 16 and further on the tether

2b until it runs against the stop ball 8 and stops. For the arrangement of the

Safety line in the respective system, see FIG. 3, 4 and 5.

The stop ball 8 is secured with stop knots on the lines or special, so-called knotless stop balls are used. The respective distance L 3, L 4 to the stop ball is calculated so that the rest of the kite lines become so loose by rushing out the control rod that the kite can blow out almost without power.

By connecting the other end of the safety lines 6, 7 and 16 to the driver's hook plate, the now powerless kite remains connected to the driver. In the event that the kite is to blow out by holding one of the kite lines over a safety line (as in FIGS. 2 and 5), the safety rules of the kite manufacturers state that the length of the rushing distance L 3, L 4 is at least 70%, better 100 %, which should result in the designed span L 5 of the kite, in order to take the power out of the kite by blowing. So while a regular quadruple kite has to open very far to become power-free, the rush length for quadruple kites with an additional center line 7 is shown in FIG. 5, comparatively ridiculously low. Practical tests have shown that the minimum length L 4 with L 4 = 0.8 x L 5/3, 14 is well dimensioned. Effect of the arrangement and its operation on the behavior of the kite with regard to the demand for a simple relaunch option without any significant linen salad after the emergency landing. The principle of the emergency landing of stunt kites when using the novel safety device is shown in the drawings FIG. 14 and FIG. 15 clarifies. FIG. 14 shows a schematic representation of a blowing, landing standard. 4-line stunt kite. The control rod 9 is replaced after release to the position of the stop ball 8. The end of the safety line 6, 16 is attached to the driver's body (not shown). For the relaunch, the driver pulls the control rod towards him by pulling the safety line towards him until he can grip the control rod. From there on, the relaunch is standard. A linen salad is not to be expected since all the other lines lie to one side of the control rod and the control rod does not land in the middle, as shown in FIG. 13 shown. FIG. 15 shows a schematic representation of a landing 4-line stunt kite with an additional center line. The control rod 9 is replaced after release to the position of the stop ball 8. The end of the safety line 7 is attached to the driver's body (not shown). Since here the flying lines are only relaxed somewhat and the control rod does not land in the middle, as shown in FIG. 13, the lines have no reason to get tangled. To relaunch, the driver pulls the control rod towards him by pulling the safety line towards him until he can grip the control rod. From there on, the relaunch is standard.

Solution to d) First, a description of how the mini safety line works is required. The core idea is to use one of the existing kite lines as an extended safety line. FIG. 11 shows the solution according to the invention. Explanation of symbols FIG. 11 In order to clarify important details, this view is not shown from the front corresponding to FIG. 5 but 180 ° from the rear. Therefore, the kite lines appear reversed. left tether line), high-strength kite line with looped lower 2 b end 2c eight-knot 2b looped end of part 2b 3 right tether (front line), high-strength kite line modified, otherwise commercially available webbing tether (GBT) or talje with block 10 and slip clamp 10a rigid buckle of GBT 10b reset loop of the GB T 10c tension loop of the GB T Mini - safety leash made from a rope with max. 3 mm 0, which is provided at both ends with a spliced bay. This only applies to the design according to FIG. 6a and 8a. For the execution according to FIG. 6b and 8b there is no separate line 16. It is replaced by a one-piece, specially assembled kite line 2b, which is continuous from the point of attachment on the kite to 16 for connection to the ring 33. Bay end of rope part 16, is tied through the loop part 2b to 16a bay knot. 40 eyelet, e.g. Stainless steel D-ring sewn on GBT, part 10 42 U - shackle or sewn-in eyelet (D-ring) 43 shackle pin 44 plastic sliding ball with hole for kite line part 2b

Mode of operation of the device according to solution to d:

The knot 2c in the kite line 2b prevents the kite line 2b from sliding through the plastic ball 44 under load, while this plastic ball 44 is held by the smaller shackle 42. This arrangement thus represents a non-positive connection in the pulling direction of the kite under load. In the event that the primary quick-release shackle 29 is actuated, the control rod 9 can now rush under load on the now tensioned line 16 until it hits the sliding ball 44. However, it must run over the node 2b, which must be slim enough because the depower cord 38 must be pulled past it within the protective tube 41 without getting tangled up. From there, this sliding ball is slid in front of the control rod on the taut kite line 2b until the sliding ball 44 is stopped by the stop ball 8, mounted on the kite line 2b. In this position the kite blows weakly.

Further requirements regarding d):

However, this arrangement of the safety line in combination with the option: "Wear-free arrangement of the power loop and safety line" according to the description and drawing FIG. 8b shows a specially assembled kite line 2b, not previously described. The reason for this is that the knot of the connection 16b from the loop 2d to the safety line 16 (see FIG. 11) is too thick to slide smoothly together with the deodorant ropes 38 through the protective tube 41 and does not close in any direction during the entry verkakeln. But since this rushing and resetting process must not be noticeably choppy, this is only possible if the Kite line in one piece from the kite to the connection to the ring 33 is free of additional knots or loops. According to the teaching of the invention, the kite line must be assembled as follows: end loop for the connection by a bay knot to ring 33, followed by a displaceable sheathing to form the knot 2c at any point, a threaded ball, a knotless, displaceable stop ball followed by the end loop or other device for the connection to the kite.

Conclusion:

The above The invention described is not limited to the illustrated exemplary embodiments but also includes those which can be used without departing from the inventive concept.

It is obvious that the purpose of the invention is achieved by the above explanation. However, it should be clear that many design changes, as some of them mentioned in the text above, can be made.
