Description

2889686 1

  The present invention relates to a control bar system for traction wings.

  Traction wings or kites are usually held by wires controlled by handles, bars or handlebars. The conventional method for flying the wing consists of deploying the wing or the wires on the ground, which requires a ground surface substantially equal to the length of the wires over the width of the wing, an order of magnitude. more than 200m2. This is a major disadvantage for the practitioner because it prevents him from accessing places from which he can not take off his wing (overcrowded beach, not enough beach width ...) and it is as much more dangerous for the spectators who, not knowing the dangers of the sport, can be caught in the son thus unrolled, son which, once in traction, become blades of razor. It is known from patent WO 01/52961 (PCT / FRO1 / 00152) in which we claim certain characteristics such as being able to wind all the wires in a housing, also integrating an integrated brake system, but since January 2000, the wings traction have evolved enormously.

  The new generations of traction sails that can be used on sand, in towed water or with a board, on snow or ice, in the air, can reach surfaces up to 25 m2 and are mainly designed to be used in 4 or 5 son, which allows a better management of the power of said sail. It was necessary to rethink the system taking into account all these new elements.

  An object of the present invention is to provide a control bar system in which the wires pass from the throat of the coil to the outputs providing total son protection for the user, even in 5 son.

  This object is achieved by the fact that the drawbar control system with integrated retractor comprises: - a housing having two opposite openings and one, two, three or more front openings and having a drive shaft passing through said housing, substantially perpendicular to the line passing through the lateral openings and the axis described by the front outlets; 2889686 2 winding members integral in rotation of said drive shaft, capable of receiving at least two windings of wire and this time presented in 4 and 5 son, each wire being adapted to be driven in translation in substantially different directions to through said openings, and two tubular elements extending said two lo openings in two directions opposite to each other and each terminating in a free end, said wires being able to pass through each of the tubular elements to open at each end free, whereby the portions of wire connected to said traction flange are capable of being elongated or shortened simultaneously of the same value, characterized in that, said housing having one or more front openings (in the axis opposite the veil) in which flexible sheaths are integrated, each sheath being connected to a clean outlet and rminant by ends, each sheath being fixed on or in the housing by any useful means to ensure a good longevity of the assembly (glue, screw, crimping or any other suitable means), the other end of the sheath being fixed either at ends allowing to vary the length of the son or safety systems in case of desired release of the wing or to one or rigid parts to firmly hold one, all, or all the sheaths together.

  Thus, a characteristic of the control bar system lies in the embedding mode of the winding members in a housing and wires in the tubular elements and the sheaths which extend the housing. In this way, the winding members and the son, in their portion located in the tubular element or the sheath, are insulated from the outside and are not likely to be hooked by the user whose hands grip the elements. Tubular during navigation.

  In addition, this new system makes it possible to take off the sail alone, with reduced spaces and to unfurl its sail when the time comes.

  It considerably improves the safety, maneuverability because the user is not obliged to unroll the entire length of son to navigate, his sail is more responsive, the comfort with the end of the entangled son and also the performance of the sails that can then be used with an ideal length of wire: with little wind we can unroll all the wires to have more amplitude and thus more power; with a lot of wind we will only run 12 to m to favor the maneuverability.

  To take off the wing, simply inflate the sail and put it in the wind, we unwind half the length of the wing flat (for a sail of 16 m2 8 m wingspan unblind 4 m of wires). We hang the threads on the wing; hook the harness end to the harness and safety to the harness or wrist; we catch the leading edge of the sail that is placed at the edge of the window and, by progressively sliding the leading edge in the hand the wing is found at the edge of the window attached to the harness.

  The invention is particularly interesting because it reduces the area required for the take-off phase of the sail and also allows to vary the length of the son according to his needs. In addition, virtually all new sails are equipped with a strap border / shock, attached to the front and connected at its other end to the end of harness, which allows to control the power of the wing by pulling it, and therefore by varying the incidence of the sail. With this new system, the strap border / shock is usable whatever the conditions and the desired length of son.

  By increasing the range of use of each sail by a better management of the length of the son, the invention allows the practitioner to save a sail to navigate in almost all conditions.

  Preferably, said housing comprises control means capable of rotating said drive shaft, whereby the length of the wire portions separating said bar system from said sail is adjustable during navigation whether in 2, 3, 4, 5 or more threads and the border / shock can be used regardless of the thread length unwound.

  Also at the end of navigation we will put his sail in the water and we will wind his son well, avoiding any entanglement of said son.

  Advantageously, said drive shaft comprises a braking means and a control means of said braking means integrated in the bar; said braking means is operable between a rest position where it blocks said drive shaft and a working position where it releases said drive shaft. Thus, when the user is in the navigation position and the unrolled distance is suitable for him, the portions of wire separating the control bar system from the sail are maintained at a fixed length by the new braking means which block the shaft. in the resting position so that the user has no effort to perform to block the son and just one manipulation: no longer press the lever and naturally return his left hand on the tube 1A; in addition to rewinding the user has only one maneuver to perform: lift the handle and rewind without taking care of anything else.

  After many tests we have retained a very effective braking system in all conditions and does not require additional blocking, including a notched wheel in which is engaged a lever, lever itself integrated in whole or part in the housing ; said toothed wheel is operable between a rest position where the lever blocks the unwinding of the son, the lever engages perfectly in one of the notches of the notched wheel because it is pushed towards the groove by a spring fixed in its location; in the working position, the lever is pressed to tilt towards you, then releasing the notched wheel to unwind the son, it could have integrated a disc brake but it would have been more expensive and more difficult to adjust. use with such a system, the user can one day turn the crank upside down which would entangle the son in the housing or transporting it, which could relax said son.

  Particularly advantageously, this new system incorporates in its winding axis a cam that ensures friction to prevent too fast or uncontrolled unlocking by transporting the bar, for example, and not to rewind in the wrong direction, which would have effect of entangling the wires. It also slows the unwinding of the wires for a better distribution of the traction of the sail.

  2889686 5 To adapt to the new sails almost all equipped with a strap of border / shock and to 80% equipped with 5 threads which increases the safety and the reappropriation of the water (indeed in case of release of the end of harness, the wing is restrained only by this Seeme thread and is flagged, thus losing all power) this new control bar system comprises a harness end connecting the loop of the releasable harness to the strap border / shock itself attached to one, more or all of the wire outlets at the front of the housing.

  In 4-wire configuration, the safety leash will be attached to one or more front or side outlets; in the 5-wire configuration, a sliding end will be attached to the end of the Seme wire outlet, which end will pass with the end of harness in the integrated channel (s) under the casing and the end of this end will itself be fixed on the safety leash that can be attached to the harness or any other part connecting the user to the bar with the possibility of dropping the leash possibly.

  This new system has advantageously brought a technical improvement because it includes guiding means that can be used for guiding the wires at the bar exit but especially closer to the coil for better accuracy of winding son; curving these guides amplifies the braking of the son for a more regular winding: in this case, stainless steel sheaths are used.

  With the evolution of the equipment and the increasing number of practitioners, some, even if the effort is important, wish to rewind in traction by placing the wing at the zenith or at the edge of the window.

  This new integrated retractor control bar system has a drive shaft that can be connected to the lever arm via a gear system to increase the winding force. Others will always look for the ultimate and will prefer effortless winding, electric winding.

  This new integrated retractable control bar system features a housing designed to receive a motor for rewinding wires underneath, above or inside. A sealed electric motor with a sufficient power to wind the wing in traction is preferably chosen.

  It is conceivable that the energy stored during unwinding would generate enough power to partially rewind the wires.

  One can imagine a battery attached to the harness, connected by a flexible power cord, connected to the housing, to power the motor so that it can rewind several times without any effort.

  With this new control bar system and its new brake locking system, it is no longer necessary to provide additional locking with the crank. On the contrary, it must be the most discreet and the most integrated and possible only for rewinding. Advantageously, this new control bar system with integrated retractor includes a crank for winding the son.

  The handle can be completely retracted during unwinding in the rest position and in working position it will be lifted. We can opt for a telescopic crank (the lever arm is telescopic and the handle tilts at the end) because it will develop a larger torque during rewinding. The handle, retractable in or on the lever arm, should allow to have a good grip.

  It can include a ratchet allowing the crank not to turn when unlocking the brake and therefore unwinding the son. It is planned to adapt a detachable handle crankable to the harness and therefore, the free axis can be driven by a cordless drill for effortless electric rewinding. The handle will of course be covered with grip or EVA or any other suitable materials.

  This new system must nevertheless be completely secure vis-à-vis third parties nearby, in case the user would drop his bar and his sail. The control bar system must therefore be protected by a protection system, and in case the wing is going to land in the water, it must also ensure its buoyancy.

  Particularly advantageously, this new control bar system with built-in retractor comprises a protection system of said housing, side duct outlets and outlets at the front; this protection dampens the entire system in case of impact with the user or a third person and also ensures its buoyancy; Such protection may be made of neoprene, foam or any other suitable material and polyurethane foam or other foam or material may also be injected into the side tubes to provide additional buoyancy.

  At the level of the lateral outlets, it will be possible to adapt the straps making it possible to compensate for any differential elongation of the lines leaving the orifices 3A and 3B.

  Figure 1 shows the new control bar system with integrated retractor, in 5-wire configuration, with the end of harness (17) attached to the border / shock (19) and the safety leash (20) attached to the end (21) and connected to the 5th wire and the passages of the sheaths (4).

  Figure 2 shows a section through the axis 1A 1B of the new brake system with the toothed wheel (12) blocked by the lever (23) pushed by a spring (24), and the cam (26).

  FIG. 3 shows a cross section of the housing (15) passing through the 2D axes 2C and 13, in 4-wire configuration with two front outlets 2C and 2D, the cam (26) and the positioning of the sheaths (4) relative to the corresponding throat.

  FIG. 4 passing through the 2D 2D axes 2C and 13 represents a cross-section of the casing (15) in the 5-wire configuration. Distances (27) for (17) and (21) are distinguished under the housing (15).

  Figure 5 shows the crank with a lever arm (10) telescopic and a handle (9) retractable in whole or part. The location is intended for the ratchet.

  The system can be designed in composite materials, carbon, aluminum or any other suitable materials. The housing (15), the tubes 1A and 1B and the outputs 2C, 2D and 2E can be molded in one piece; the brake system (12 and 23) will advantageously be made of aluminum or any other suitable material. The rest of the parts to design (flanges, sleeve holding part ...) must be very light to promote buoyancy and resistant.
