Definitions

  • the invention relates to a kite of the type with frames intended to stretch its canvas (s).
  • the secondary reinforcement for its part, comprises, in the current state of the art, one or more pairs of small rods, bearing on one side on the transverse rod or rods and coming, on the other tender side or push the canvas or other floating frames outside the plane of the main frame.
  • the invention relates more particularly to this second type of frame, called according to the country: "Whiskers”, “Wiskers”, “Stand Off”, “tensioners”, “pushers”, etc.
  • this type of frame will be called “Wiskers”.
  • the object of the invention is to overcome the drawbacks of the prior art, some of which have just been mentioned.
  • a secondary frame always comprising at least one pair of "wiskers” but arranged differently.
  • each pair of wiskers are extended, until they bear against each other, in the median plane of symmetry. These two ends can then be positioned in an optimized manner in this plane, and the maintenance of this position is carried out by a simple clamping comprising at least one strand on the central strip.
  • the subject of the invention is therefore a kite of the type comprising at least one canvas and a main frame made up of longitudinal and transverse strips, and a secondary frame comprising additional strips used to stretch the rear edge of the canvas or to provide it curves, the kite having a median plane of symmetry; characterized in that said additional rods come to bear one on the other on a structure at a junction point located in the median plane of symmetry and at a distance from the transverse rods.
  • a small complementary fabric forming a keel or drift in the median plane has several interests: guiding the kite by stabilizing its trajectory, which is important during takeoffs; brake the kite and break its inertia when doing a very tight looping, which is important to slow down a kite and make it land.
  • the kite being supported on its daggerboard picks up the wind alone, without needing to turn it around, or without the help of another person.
  • Fig. 1 represents a kite 1 of the "Delta" type of the known art. It comprises a main frame made up, as has been indicated, of a median longitudinal rod 10, of one or more transverse rods 11 and 11 ′ (in the example illustrated), connecting two longitudinal rods 12 and 13 to each other.
  • the baguettes transverse are not in contact with the fabric 15 of the kite 1 but they are fixed on the longitudinal rods using junctions 14.
  • junctions 14 are for example fixed on the rods 12 and 13 and have an orifice in which the ends of the transverse rods 11 and 11 'are threaded.
  • the front of the fabric 15 comprises a sheath 150 in which the rods 10, 12 and 13 are threaded.
  • the fabric 15 is fixed to the rear ends of the rods 10, 12 and 13 using conventional fixing means 11 (elastic slot for example).
  • Two sets of flanges 17 are provided to distribute the forces exerted on two cables 18 of the kite 1, themselves wound on a pair of control handles 19, on the frame of the kite 1 and, so, get a flight driving.
  • the flanges 17 of each set are connected, at one of their ends, to the side strips 12 and 13, on the one hand, and to the central strip 10, on the other hand .
  • the secondary reinforcement comprises in particular one or more pairs of wiskers 2, connected by one of their ends to the fabric 15, by attachment means 20, and supported by the other end , on the transverse rod or rods, in this case the transverse rod 11 in the example illustrated.
  • junctions 21 of a type analogous to junctions 14 are provided.
  • Fig. 2 partially illustrates a kite 1 of a type similar to that of FIG. 1 but incorporating the provisions specific to the invention.
  • Fig. 3 schematically illustrates this same kite 1, in rear view.
  • the main frame is quite similar to that described above because it is not directly concerned with the invention. It is therefore unnecessary to describe it again.
  • the guide flanges 17, the cables 18 and the handles 19 have not been shown either (Fig. 1).
  • the pair or pairs of wiskers 2 no longer rest on the transverse rod or rods, the rod 11 in the example illustrated in FIG. 2, but extend until they meet in the median plane P (Fig. 3) of the main frame of kite 1.
  • the corresponding ends of the wiskers are connected to each other by any suitable joining means 22. It may be a two-part joining 220 and 221 as illustrated in FIG. 4. These two parts 220 and 221 can be movable in rotation about an axis d and include orifices 2200 and 2210, respectively, into which the ends of the wiskers 2 to be connected can be introduced. The other ends are fixed at 20 to the fabric 15 in a conventional manner.
  • the wiskers are kept in a fixed position relative to the main frame using flanges 23 and 24, or similar means.
  • flanges 23 and 24 are attached, at one end to the junction 22, and by another end to the longitudinal center strip 10, respectively towards the front and towards the rear of the kite 1.
  • junction 22 is advantageously provided with a fastening means 223, for example in its lower part, itself provided with an orifice 2230, or any other similar means: hook, ring, etc.
  • the flanges 23 and 24 form a V-structure included in the median plane P (Fig. 3), while the pair of wiskers 2 forms also a V-shaped structure but orthogonal to the previous structure.
  • the invention has the advantage of being able to position the junction point 22 at will in the plane P (Fig. 3).
  • the distance separating the junction point 22 from the rod 10 depends on the effective length of the wiskers 2.
  • the junction point 22 can be placed towards the rear, as for example in FIG. 5, towards the front, or at any other position depending on the respective lengths of the flanges 23 and 24.
  • the links forming the flanges 23 and 24 are made of non-elastic material, of the strap or twine type for example.
  • these flanges 23 and 24 can be made of elastic material, which makes it possible, as has been indicated, to compensate or "absorb" the variations in the wind (gusts, etc.) and thus make the kite 1 particularly silent whatever the flight conditions.
  • This role can also be played alone or in addition to the flanges, by the secondary reinforcement. More precisely, it suffices to make the wiskers 2 in elastic material, which is generally the case.
  • the number of flanges associated with each pair of wiskers 2 is at least two.
  • the pair of wiskers 2 will be more or less inclined, towards the front or towards the rear of the kite 1.
  • the flange 25 can be rigid or elastic.
  • Fig. 8 illustrates a second embodiment of a kite according to the invention.
  • an additional canvas 4 is added, arranged at the tail of the kite 1.
  • This canvas 4 serves as a fin or keel in the median plane P (FIG. 3). It is tensioned using wiskers 2, either directly or by calling, as illustrated in FIG. 8, to an additional rod 3.
  • This additional strip is supported on the longitudinal central strip 10, using a junction element 31 similar to the elements 14 (Fig. 1), by one of its ends.
  • the additional fabric 4 can be attached to the other end at 30 in a similar manner to the fastening means 16 (Fig. 1). It is possible to provide in the canvas 4 a sheath in which the rod 3 is threaded, while preserving an opening 40 leaving an area of the rod accessible to fix it at the junction point 22.
  • the joining element 22, as illustrated in FIG. 4 can moreover be fixed on the rod 3. It suffices, for example, to provide an orifice 2230 of sufficient diameter to thread the rod 3 into it.
  • the flanges 23 and 24 become unnecessary.
  • the canvas additional 4 will then have a substantially V-shaped cutout connected, at at least two extreme points to the rod 10, on the one hand, and to the junction point 22, on the other hand.
  • the rod 30 is threaded into the additional fabric 4 using a sheath.
  • the use of a fin has several advantages, in particular being able to guide kite 1, by stabilizing its trajectory, braking it and breaking its inertia when performing a tight looping and make it land.
  • the additional fabric 4 can be made of different materials, more or less porous, which makes it possible to limit the stabilization effect to a determined degree, depending on the model of kite.
  • the fabric 4 can be provided with orifices distributed regularly to form a keel.
  • kites having the general configuration of a "Delta” this current configuration having been retained only to better describe the invention. It applies to any kite having a main frame intended to stretch its canvas (s) and a secondary frame of the type using pairs of elements known under the name of "wiskers”, as it has been defined. in this description.
  • the number of these pairs of wiskers is not limited to one pair. We can just as easily use two or more pairs depending on the type of kite.
