Abstract

Sail propulsion is proposed for land, ice and water craft, in particular sailboards, in which, according to Fig. 1, the halves of a dragon sail (1, 2) are arranged at an obtuse angle to one another symmetrically to a centre plane, and the lateral corners of the dragon sail (1, 2) are connected to the lateral corners of a second dragon sail (3). Both sails are held spread on the masts (4, 5) and on the wishbone (6, 7, 8). The lower member (8) of the wishbone (6, 7, 8) serves as handle. <IMAGE>

Description

description

The invention relates to a kite rig for sailboards and other sailing vehicles, in which the halves of a kite sail symmetrical about a median plane at an obtuse angle arranged to each other and the side corners of the kite sail with the side corners of a second kite sail are connected.

The state of the art is characterized by self-supporting kite rigs in a V shape. Deviating from the hang glider is dispensed with bracing with wires. The demands for sufficient stability and low weight force therefore to a limitation of the span or the sail area.

The previous attempts with kite rigs have shown

sen that 6-8 m sail area is not enough to achieve an improvement in performance compared to conventional rigs. In particular further flights or higher speeds could not be shown.

To avoid the disadvantages mentioned, it is proposed in German patent application P 32 43 435.9 of 11/24/82 to connect two kites at the wing ends to form a double kite. The lower kite is V-shaped. The upper kite can be designed either V-shaped or flat.

In one embodiment of the German patent application P 32 43 435 · 9, the upper kite consists of two crossed ones Pipes and a square sail. The lower kite will be out

· ■■ ο ™ *

two side tubes, a V-shaped control bracket and one Triangle or square sails formed.

In a further exemplary embodiment of the German patent application P 32 4b5 ^ 35 · 9 can be the side tubes of the lower Dragons are omitted.

Opposite self-supporting kite rigs in V-shape offer double kites significant benefits. With the same span, the sail area is doubled. The improved stability allows a weight reduction of the pipes. In addition, the handling of a double kite is much easier than that Handling of a self-supporting kite with the same sail area.

Disadvantageous in the embodiments of the German patent application P 32 43 4-35 · 9 is the shape of the sail-bearing Linkage. A maximum stability of the double kite with minimum weight cannot be achieved with this.

The object of the invention is a kite rig for sailboards and other sailing vehicles that has the disadvantages described avoids. Primarily, the stability, weight and handling of the kite rig should be in an optimal relationship to one another to be brought.

To solve the problem, both kite sails become a double kite stretched on a rod, which consists only of a pipe transverse to the central plane and a double tree exists in the central plane.

Triangular or square sails are defined as kite sails,

whose halves are symmetrical with respect to the center line of the sail and whose leech is blunt or form straight angles.

The technical terms are taken from the language of sailors, surfers or hang-gliders and are accordingly interchangeable. For example, the side tubes k, 5 can be referred to as masts or a mast and the double boom 6, 7j 8 as a boom.

Parts of the rods and sail bags covered by the sail are shown in dashed lines, ropes, ropes and pods are shown in dotted lines.

In an exemplary embodiment according to FIG. 1, the lower kite sail 1, 2 and the upper kite sail 3 are stretched on the lateral ends of the side tubes 4, 5 and on a double boom 6, 7, 8. The upper tree 6, 7 here consists of the keel tube 6 and the nose spur 7 pointing forward and down, while the lower tree 8 serves as a keel tube and control bracket. Both trees are arranged in the central plane. The fixed or pluggable connected side tubes k, 5 are attached to the front end of the keel tube 6 above or below the upper tree 6, 7 by means of ropes, couplings or joints. The upper kite sail 3 is attached in the area of the side _{leech to the nock of the double boom 6, 7 5} 8 _{by means of sail pockets 9 5} 9 ' ^a * in the side tubes 4, 5 ^ rait in the middle of the aft leek. The lower kite sail 1, 2 is stretched with the lateral corners at the lateral ends of the side tubes 4, 5 »with the front corner on the head part of the double boom 6, 7j 8 and with the rear corner on the middle third of the lower boom or control bracket 8. Here are the halves of the lower Draclien

segeis 1, 2 symmetrical to the median plane in a blunt Arranged at an angle to each other and the side corners of both kite sails 1, 2 and 3 connected to one another.

Triangular or square sails, their halves, can serve as the lower kite sail 1, 2 and the upper kite sail 3 are symmetrical with respect to the center line and the leech forms an obtuse or straight angle. In addition, all sail shapes known from hang gliders are usable.

Z ^^ r reduction of the air resistance can the lower kite sail 1, 2 and / or the upper kite sail 3 in the center line be provided with sail bags for the lower tree δ and / or the upper tree 6, 7. The sail bags have here recesses for the side pipe-tree connection and the hands holding the rig.

According to Figs. 1 and 2, the upper tree 6, 7 and the lower tree 8 can be curved upwards or downwards or a parallelogram with identical or unequal pairs of sides form.

The side pipes 4 ', 5, the side pipes Ik, 15 and the trees 6, 7 and 0 can be designed telescopically.

In a kite rig according to Fig. 2, the double boom is 6, 7j 8 at the head end, at the nock and in the middle third of the trees 6, 7 and ü with lockable joints 10, 11, 12, 13 strand.

Fig. 3 shows an embodiment in which on the headboard

of the double tree 6, 7j 8 and at the lateral ends of the Side tubes 4, 5, which are fixed or pluggable connected in V-Forra Side tubes 14, 15 are attached. Here is the kite sail 1, 2 with sail bags 16, 16 'for the Side pipes 14, 15 provided.

To adjust the angle between the kite halves, the side tubes 4, 5 and the side tubes 14, 15 Connected in the central plane by lockable joints be.

Propulsion and lift increase when the kite sails 1, 2 and 3 are designed as double sails. Here have the Side tubes 4, 5 and 14, 15 preferably have an elliptical or teardrop-shaped profile.

The kite sails or double sails 1, 2 and 3 can be fitted with battens, ribs or inflatable profile bodies Asymmetrical wing profile received.

Dragon rigs with two kites connected at the wing tips can serve as a sail drive for skis, water skis, snow boards, ice skates and skateboards or as hang gliders, _ Tails and motor kites are used.

The effort of the sailor can be reduced considerably if the lower tree 8 with the sailing board or sailing vehicle is connected by a mast, sheet, cockpit or keel sail.

Alternatively, a leash can be attached to the lower tree 8, which can be attached to a harness, hip belt or seat belt is hookable.

A double kite can also be outside the mid-plane \,

The handling of the kite rig is made easier if one or two sails are arranged in the center plane and preferably are stretched by means of sail bags on the trees 6, 7 and / or 8.

The kite sails 1, 2 and 3 can by rigid wings, preferably plastic wings should be replaced.

Aerodynamic steering aids can preferably be placed on the lower kite sail or Wing 1, 2 can be attached.

Waiving sail area, it is possible, the lateral corners of the kite sail 1, 2 itenrohre to the middle thirds of the S _e k and 5 to span.

In weak to medium wind, one end of the side tube k or 5 can be connected to the sailing board or sailing vehicle by a rope, a coupling or a mast foot joint 18.

be bound. In an embodiment according to Fig. 6, the two-part or telescopic side tubes are 4 and lA shortened and the lower halves of the Kite sails 1, 2 and 3 reefed. The symmetrical kite sails 1, 2 and 3 can be removed and replace with asymmetrical sails.

In a kite rig according to Fig. 7, a third kite sail 19 is stretched with the corners at the side ends of the side tubes k and 5 »with the front corner on the middle third of the nasal spur 7 and the rear corner on the rear part of the tree 8.

According to Fig. 8, the side tubes k, 5 can be moved forward and down and laid in sail pockets 20, 20 'on the leech of the kite sail 19. The sail pockets 9, 9 'of the kite sail 3 are omitted.

The lateral tips of the kite sails are used to reduce the span while the sail area remains almost the same 1, 2, 3 and / or 19 cut off and the rear lateral ones Corners of the kite sails stretched on wingtips or swing tips .
