Definitions
- the invention relates to a device for winding the flexible wire for retaining a kite, comprising: a gripping bar equipped with a rotary winder for winding and progressively unwinding the length of line desired by the pilot, - means for releasing the reel during the unwinding of the winding under the action of the traction exerted on the wire, and means for manual rewinding by reverse rotation of the reel.
- Control rods of the kind mentioned are generally used to direct traction kites for nautical use by means of two lines of wire which may be several tens of meters in length.
- the object of the invention is to provide a device for winding the retaining wire of a kite, which can be easily maneuvered and has a light and robust structure, as well as a reduced manufacturing cost.
- the device according to the invention is characterized in that the reel comprises: - a straight support arm mounted for free rotation on an axis perpendicular to the gripping bar, two fork-shaped stirrups secured to the opposite ends of the support arm for the establishment and storage of the wire, and means for self-locking of at least one stirrup during the rotation of the reel in the direction of the unwinding of the wire.
- the two stirrups are diametrically opposite with respect to the axis by being arranged on either side of the direction of extension of the support arm with a predetermined angle of inclination.
- the means for unlocking the reel are fixed to line guide pads. They include elastic sheaths for the passage of the line wire and intended to cooperate with hooks located on stirrups to occupy either a unidirectional locking position or an unlocking position, respectively to prevent or allow the unwinding of the winding of the wire under the pulling effect exerted on lines by the kite, the passage from the locking position to the unlocking position is effected manually by a simultaneous movement of the two sheaths or lines outside the trajectory of the hooks.
- the studs protrude from the grip bar, and include adjustment means for adjusting the spacing as a function of the kite's airfoil.
- a crank is carried by at least one stirrup to authorize the manual rewinding of the wire on the reel following a rotation movement opposite to that occurring during the unwinding.
- a brake is associated with the reel, and comprises a first braking flange secured to the rotary support arm and cooperating by friction with a second braking flange fixed to the gripping bar.
- the axis of the reel crosses the two brake flanges and cooperates with a clamping nut to modulate the friction force between the two flanges.
- Figure 1 is an elevational view of a winding device of a kite according to the invention, the retaining wire is not shown on the reel;
- - Figure 2 shows a plan view of Figure 1, the support arm of the reel being oriented parallel in the longitudinal direction of the gripping bar;
- Figures 3 and 4 are identical views of Figures 1 and 2 with the winding of the wire on the reel;
- Figure 5 is a sectional view of the brake of the reel;
- - Figure 6 shows a partial view of Figure 3 during the passage of the elastic sheath or wire to the unlocking position of the reel allowing the unwinding.
- a device 10 for winding the flexible wire for retaining a kite comprises a gripping bar 12 fitted in the part central of a rotary winder 14 for winding or progressively unwinding the length of a pair of lines 16A, 16B left and right of the retaining wire.
- the reel 14 comprises a straight support arm 18, which is mounted for free rotation on a fixed axis 20 extending perpendicular to the gripping bar 12.
- Two stirrups 22A, 22B shaped according to U-shaped forks, are fixed at the ends opposite support arm 18 rotating to ensure the establishment and storage of the retaining wire.
- At least one of the stirrups 22A, 22B is provided with a crank 24 authorizing the manual rewinding of the lines 16A, 16B left and right of the retaining wire when the reel 14 rotates clockwise.
- the two stirrups 22A, 22B diametrically opposite with respect to the axis 20 of the reel 14, are arranged on either side of the direction of extension of the support arm 18 with a predetermined angle of inclination, for example of the order of 40 °.
- the rotational movement of the reel 14 can be controlled by means of a brake 26 comprising a first braking flange 28A secured to the support arm
- a second braking flange 28B fixed to the gripping bar 12.
- the two braking flanges 28A, 28B are crossed by the axis 20, the threaded end of which is provided with a nut 30 clamp for manually modulating the friction force between the two flanges 28A, 28B.
- An anti-rotation washer 31 is interposed between the nut 30 and the grip bar 12 to prevent rotation of the axis 20 when the brake 26 is adjusted.
- the lines 16A, 16B are guided by two studs 32A, 32 B projecting from the gripping bar 12, extending parallel to the axis 20.
- the wire can slide around axes 34 arranged at the upper part of the studs
- the spacing of the two studs 32A, 32B is adjustable along the longitudinal direction of the bar. gripping 12.
- the axes are positioned in a plane parallel to the gripping bar 12 and passing in the vicinity of the hooks 38A, 38B.
- Each pad 32A, 32B can be provided with an elastic sheath 36A, 36B for the passage of the retaining wire, which is wound on the reel 14 placed between the pads
- the sheaths 36A, 36B prevent wear of the wires on the hooks 38A, 38B, and constitute springs cooperating with hooks 38A, 38B of unidirectional locking, which are integral with the stirrups 22A, 22B.
- the sheaths 36A, 36B interfere with the hooks 38A, 38B by constituting non-return pawls which prevent the unwinding of the winding 40 of the wire under the pulling effect (arrow T, FIG. 3) exerted on lines 16A, 16B by the kite.
- the reel 14 remains fixed while being locked in rotation in the anticlockwise direction.
- the unlocking of the reel 14 anticlockwise is made possible by simultaneous manual movement of the sheaths 36A, 36B towards an unlocking position (arrow F1, FIG. 6).
- the hooks 38A, 38B of the two stirrups 22A, 22B are then released by authorizing the unwinding of the winding 40 under the pulling effect T exerted on the lines 16A, 16B.
- the release of the sheaths 36A, 36B causes the return to the unidirectional locking position causing the automatic rewinding of the reel 14 during a complete half-turn.
- the winding 40 of the wire around the two stirrups 22A, 22B of the reel 14 has a substantially oblong or ovoid shape, and tends to be positioned in the longitudinal direction of the grip bar 12 when the stirrups 22A, 22B come in stop against sheaths 36A, 36B.
- the reel 14 having a support arm 18 with a length of 35cm corresponds to a reel conventional round 22 cm in diameter. This results in a gain in size, and a large storage capacity of the retaining wire.
- the two elastic sheaths 36A, 36B for the passage of the wire towards the reel 14 can be produced by any other guide member making it possible to gradually release the length of line desired by the pilot of the kite.
