Definitions

  • the present invention relates to a steerable flat kite with the features of the preamble of claim 1.
  • Steerable flat kites are known in manifold designs, these designs differing in shape, for example. Together, on the other hand, such flat kites have a transverse and a longitudinal strut, which form a linkage for the sail, which is usually also referred to as covering. On this sail and / or the rod in the known flat kites a 2-, 3-, 4- or higher-legged scales are attached, on which the control line engages, so that the user has the tensile stress required for controlling the kite via the control line Leg of the scale can transmit, which changes the flight position of the kite and thus the desired control movement of the kite is brought about by increasing or decreasing the wind resistance.
  • the known kites described above thus carry out each change of direction only in the form of an arcuate airline, i.e. when changing direction, the kite always flies a more or less curved curve line from the original position to the new position.
  • This change in flight direction caused by a rotation of the kite often leads to the fact that the flight stability of the kite is adversely affected, so that the kite begins to spin accordingly.
  • Such a kite can also be braked during the flight and in particular also not during a change of flight direction, so that overall the control options of the known flat kites desired by the operator are limited.
  • the present invention has for its object to provide a kite of the type specified, which has a particularly large variety of control options.
  • a steerable flat kite which has a linkage comprising cross and longitudinal struts, a sail attached to the linkage and a scale arranged on the sail and / or the linkage, to which at least one control line can be attached.
  • the kite is formed from at least two individual kites, which are connected to one another via their cross struts in such a way that the individual kites can be rotated relative to one another about the cross struts as the axis of rotation.
  • the individual kites also have an identically sized sail area, with each individual kite being assigned at least one scale, which comprises at least two balance ropes, so that such a balance can also be referred to as at least two-legged balance.
  • At least one scale rope of the scale from each individual kite is attached to the sail and / or the longitudinal strut above and below the cross strut.
  • the flat kite according to the invention thus has at least two individual kites which are connected to one another and rotatable relative to one another about their connecting axis, which have an identically sized sail area and which are individually controlled by at least one scale and an associated control line, so that the position of the individual kites for Wind can be adjusted individually.
  • the kite designed according to the invention has a number of advantages. In comparison to a suitably designed single kite, it is characterized by a high level of flight stability, which is particularly noticeable when changing direction. This is due to the fact that when the kite according to the invention changes direction it is not necessary to turn the entire kite. Rather, in the simplest embodiment of the kite according to the invention, which consists of two single kites, the position of one single kite to the wind is changed while the other single kite remains in its usual position. As a result, the total resistance of the kite changes on one side, ie the resistance on the side of the single kite, the position of which has been changed, is increased or decreased depending on the change in position carried out.
  • kite changes its flight direction depending on the size of the change in position of the individual kite, so that it is possible with the kite according to the invention is to fly every change of direction at an angle between 1 ° and 360 ° to the original flight direction.
  • the position of the other individual kite is generally not changed during such a change of direction, the flight stability and controllability of the kite is retained for this reason.
  • the kite according to the invention to brake the kite abruptly in flight without the kite falling undesirably. Due to the construction of the kite according to the invention described above, it can also fly in all directions at the same speed in a flight-stable position, it being only necessary to adjust the position of the individual kites relative to one another to the respective wind conditions.
  • Embodiments of the flat kite according to the invention in which the individual kites are additionally shaped identically have particularly good flight and steering properties.
  • kites whose individual kites have rectangular and in particular square sails are particularly suitable with regard to the steerability.
  • the simplest embodiment of the kite according to the invention consists of two individual kites. Of course, however, it is also possible to provide more than two individual kites, for example three, four, five or six individual kites, but it may be necessary with increasing number of individual kites that these kites are then operated by several people at the same time.
  • kite consists of two individual kites, which are covered with a rectangular or square sail.
  • the two sails of the individual kites are still connected to one another in the area of a corner point, this connection being designed in the simplest case by the corresponding overlapping corner points of the sails being sewn or glued to one another. It is also possible to connect these corner points to one another using mechanical fasteners, such as press studs, zippers or Velcro straps. This additional connection of the sails via the corner points increases the stability of the kite, so that, for example, fluttering of the sails during flight is avoided.
  • This additional connection can also be designed in such a way that the rotatability of the individual kites relative to one another about their transverse struts as the axis of rotation is limited, so that even inexperienced users cannot override such a kite and can thus bring it into a flight-unstable position.
  • the cross struts can be connected to one another via a corresponding plug connection to form a common cross strut, the plug connection of course having to be designed in such a way that the free rotation of the individual kites relative to one another is not hindered thereby.
  • this is ensured in that the cross strut of the first single kite has a guide sleeve in the region of its connecting section with the cross strut of the next kite, into which the corresponding section of the cross strut of the next kite is inserted, and which has such a diameter that the cross strut of the next kite is freely rotatable therein.
  • the cross struts are designed as a one-piece cross strut, the sails of the individual kites then being freely rotatably attached to this common cross strut.
  • suitable fastening means such as loops, eyes and the like, are attached to the sails.
  • loops, eyes and the like are attached to the sails.
  • suitable fastening means such as loops, eyes and the like
  • a particularly suitable embodiment of the kite according to the invention provides that the common one-piece cross strut or the interconnected cross struts of the individual kites is or are arranged in appropriately shaped pockets, which are each provided in the sail of the individual kite. These pockets cause the sails of the individual kites to be rotatable relative to one another about the cross strut or the cross struts as the axis of rotation, without there being any risk of the cross struts sliding out of the sails.
  • the bag can be provided with only one opening as well as with two openings at the ends, in which case it is then necessary to fix the ends of the sails to the corresponding section of the cross strut or the cross struts, which is particularly good by corresponding elastic fastening elements can be achieved as described below.
  • each individual kite has at least one longitudinal strut which is arranged depending on the shape of the sail. With one right angular or square sails, it is advisable to provide a longitudinal strut, which is arranged at an angle of approximately 90 ° to the cross strut. Of course, if necessary, more than one longitudinal strut can also be provided, as is also known for the corresponding individual kites.
  • the longitudinal strut extends between the opposite corner points of the rectangular or square sail, such a longitudinal strut preferably being arranged at an angle of 90 ° to the cross strut. This ensures that the sail is stretched accordingly over its entire surface.
  • a further embodiment of the kite according to the invention has elastic fastening elements which are each arranged at the ends of the cross and longitudinal struts and which are each fastened to the sail.
  • these elastic fastening elements allow the above-described rotation of the individual kites relative to one another without causing damage to the sails.
  • these fastening elements are designed as elastic cords.
  • a particularly durable fixation of the sail to the end regions of the longitudinal and transverse struts can be achieved by using loop-shaped elastic fastening elements which are attached to the end region of the longitudinal and transverse struts, for example via an eyelet or a loop on the sail and via a metal ring .
  • kitse according to the invention can be controlled particularly precisely, in which each rectangular or square individual kite has two three-legged scales.
  • the longitudinal strut and the cross strut are arranged in a cross shape for each individual kite and extend between the corner points of the sail.
  • the two individual kites are also connected to each other via a corner point.
  • the two scales of each individual kite are arranged in such a way that two scales of each scale are attached to the sail at the end of the cross strut and the longitudinal strut or to the end regions of the cross and longitudinal struts (while the third balance rope in each case) of each scale in the area of the corner point at which the two individual kites are connected to each other.
  • the rod of the kite according to the invention can be made from any material that has a sufficiently high strength.
  • any material that has a sufficiently high strength for example, it is possible to use wooden or metal rods as the material for the linkage, but plastic rods in particular have the best properties in terms of low weight and high strength.
  • the kite according to the invention can either be a high-strength paper covering or a covering made of plastic as a sail films or in particular have a covering made of a fabric, which fabric is either set very tightly or provided with a corresponding coating, so that it is accordingly windproof.
  • Particularly good flight characteristics of the kite according to the invention can be achieved with a sail which, seen in the longitudinal and transverse directions, has the same or approximately the same elongation behavior.
  • This can be achieved, for example, by selecting a fabric as the sail that has the same or approximately the same elongation behavior in the warp and weft directions, which can be achieved in particular by using a fabric whose warp and weft density is identical .
  • the sail is selected so that an angle of attack ⁇ between 10 ° and 30 °, preferably between 12 ° and 15 °, is established at wind pressure.
  • a kite designated overall by 1 in the figure, has two individual kites 2 and 3 in the embodiment shown there, which are connected to one another via their cross struts 4 and 5 in such a way that the individual kites 2 and 3 are arranged relative to one another in the direction of arrow 6 and 7 around the cross struts 4 and 5 are rotatable as an axis of rotation.
  • the cross struts are arranged in a pocket open on both sides, which extend over the entire length of the cross struts 4 and 5.
  • each individual kite 2 or 3 has a longitudinal strut 8 or 9 which tensions the sails 10 and 11 of the individual kites.
  • the two individual kites 2 and 3 are connected to one another in the area of a corner point 12 such that the corresponding areas of this corner point overlap.
  • This additional connection is achieved in those embodiments in which the sails 10 and 11 consist of a fabric in that the sails are sewn together at their additional connection area 12.
  • Each single kite 2 or 3 has two three-legged scales, generally designated 13 and 14, as is shown only for the single kite 2.
  • two balance cables 13a and 13b extend to the end regions 15 and 16 or 16 and 17 of the square sail 11, while the third balance cables 13c and 14c are fastened to the connection region 12.
  • an adjustable eyelet 18 and 19 is arranged, to each of which a control line 20 or 21 is fastened leads the user of the kite.
  • the eyelets 18 and 19 are connected to one another via a weighing line 23.
  • the actuation of the control line 21 causes the individual kites 2 and 3 to be rotated relative to one another in the direction of the arrows 6 or 7 via the scales 13 and 14 or via the corresponding scales (not shown) of the single kite 3.
  • This means that the wind resistance of the entire kite can be changed in certain areas, so that the kite 1 can fly stable in any direction.
  • the kite 1 can be stopped in each flight phase and steered in a different direction, for example in the opposite direction.
  • the cross strut 5 has a guide sleeve 30 which surrounds the cross strut 4 in its end region and thus rotatably supports.
  • the guide sleeve 30 has a diameter d1 which is slightly larger than the diameter d2 of the cross strut 4, so that the cross strut 4 can be rotated within the guide sleeve 30 in the direction of arrow 6 or vice versa.
  • FIG. 3 shows a further detailed view, which shows a possibility of fastening the sail to the linkage, for example on the previously described cross struts 4 or 5 or the longitudinal struts 8 or 9, using the example of an end region 5A of the cross strut 5.
  • the end region 5A of the cross strut 5 has a cap-shaped coupling element 40, which is held by clamping engagement on the end region 5A of the strut 5.
  • a ring 41 for example an O-ring made of metal, is attached to the cap-shaped coupling element 40.
  • the sail 11 has in its ent speaking corner point also a suitable fastener 42, which fastener 42 may be formed as a fabric loop or also as an O-ring.
  • An endless elastic fastening element 43 extends between the ring 41 and the fastening element 42.
  • the elastic fastening element 43 ensures that the sail is always subjected to the required tension, so that it is accordingly tensioned, and also in the direction of the arrow 44 or vice versa can be moved so that there can be no damage to the sail when rotating the individual kites relative to each other.
  • the sail has an area which is permeable to air. This ensures that the wind pressure on the kite sail is reduced in this embodiment of the kite, so that such a kite can be handled perfectly even at high winds.
  • This air-permeable area also means that kites that have a correspondingly large sail area can still be controlled without the respective user having to absorb extreme tensile forces that are transmitted from the kite to the user via the scales and the control line.
  • kites which consist of a plurality of individual kites, for example four to eight individual kites
  • these air-permeable areas preferably being arranged symmetrically in each sail area of the individual kite are.
