Fig. 1 shows a profile sailing device 100 with outer sail surfaces 102, 104 and an inner skeleton structure 106. The profile sailing device 100 is used to drive a sailing vehicle not shown here. The skeleton structure 106 predetermines the shape of the profile sailing device 100. The sail surfaces 102, 104 are stretched over the skeleton structure 106. The profile sail device 100 has a first sail surface 102 and an opposite second sail surface 104.

Between the sail surfaces 102, 104, a cavity 108 is formed, in which the skeleton structure 106 is arranged.

The profile sailing device 100 has a wing profile with which a dynamic propulsion can be generated by means of a wing effect. The airfoil profile of the profile sail device 100 is adjustable. A first operating position for an inflow of the first sail area 102 can be set and a second operating position for an inflow of the second sail area 102 can be set. In this case, the approaching sail area on a convex curved surface. The opposite sail surface has an S-shaped curved surface. The profile sail device 100 has a profile nose 110 with a nose radius and a profile trailing edge 112 with a trailing edge angle. The longest line from the profile nose 110 to the trailing edge 112, which is identical to the chord, determines the tread depth. The profile curvature results as the greatest possible deviation of the skeleton line from the chord. As a skeleton line, the line which lies in the cross section of the profile sailing device 100 exactly between the sail surfaces 102, 104, referred to. The profile contour profile sail device 100 is therefore symmetrical about its skeleton line. Another definition is: The skeleton line is the connecting line of the circle centers inscribed in a profile. The profile thickness is the largest possible circle diameter on the skeleton line within the profile. The profile curvature significantly determines the maximum propulsion and is essential for a moment coefficient.

The sail surfaces 102, 104 may consist of a woven cloth made of synthetic fibers. The sail surfaces 102, 104 may be formed with a laminate sail, in which fibers are glued to films or a fabric. The sail surfaces 102, 104 may be formed with a membrane sail, are introduced in the reinforcing fibers already in the manufacture of the sail according to an expected load line. The sail surfaces can 102, 104 synthetic fibers, for example of polyamide, polyester, Polyethylennaphtalat, aramid, and / or carbon fiber, have.

The skeleton structure 106 has a plurality of, in the present case 19, frame means, such as 114. The frame devices 114 each have three mutually adjustable frame elements. Thus, the profile sail device 100 can be adjusted such that in the first operating position, the first sail surface 102 to be fed Wing side and the second sail area 104 forms a back and in the second operating position, the second sail area 104 forms the inflowing wing side and the first sail area 102 forms a back.

The profile sail device 100 is arranged on a mast 116. The mast 116 extends in a hoisted profile sail device 100 in the cavity 108 and through opening in the frame means 114 therethrough. There is a play between the edges of the openings and the mast. The frame means 114 are limitedly displaceable on the mast 116. The frame means 114 are slidable on the mast 116 in the direction of the mast axis. The frame means 114 are pivotable about the mast 116. Thus, the profile sail device 100 is pivotable about the mast 116. The mast 116 extends in the airfoil profile behind the profile nose 110 so that a smaller portion of the tread sail 100 extends between the mast 116 and the nose 110 and a larger portion of the tread 100 between the mast 116 and the trailing edge 112. The mast 116 is presently fixed, in particular rotationally fixed, connected to a vehicle body, such as a boat hull. The mast 116 may be on a keel and passed through a deck. Alternatively, the mast 116 may be on the deck and supported from below on a keel.

Fig. 2 1 shows a frame device 200 of a profile sail device, such as a frame device 114 of a profile sail device 100 according to FIG Fig. 1 , with three frame members 202, 204, 206. A frame member 202 is a central frame member. A frame member 204 forms a profile nose side portion of the frame means 200 and thus the airfoil profile. A frame member 206 forms a profilhinterkantenseitigen portion of the frame means 200 and thus the airfoil.

The frame element 202 has a greater width at its end 210 facing the profile nose 208 of the airfoil profile than at its end 214 facing the profile trailing edge 212. The frame element 202 progressively narrows from its end 210 to its end 214. The frame element 202 has lateral spars 216, 218, which form a profile contour. The spars 216, 218 are stabilized with ribs 220. The frame element 202 has in the region of its end 210 a hinge connection 222 for the articulated connection with the frame element 204. The frame member 202 has in the region of its end 214 a hinge connection 224 for articulated connection with the frame member 206. The frame member 202 has a main extension plane in which the spars 216, 218 and the ribs 220 extend. The hinges 222, 224 have axes that are orthogonal to the main plane of extension. To form the articulated connections 222, 224, openings and / or pins are provided on the frame element 202.

The frame member 204 has a drop-like outer contour. One end 226 of the frame member 204 forms the profile nose 208 of the frame 200 and thus the airfoil. An end 228 of the frame element 204 facing the profile trailing edge 212 has a coupling section 230. The coupling section 230 serves for a kinematic coupling with the frame element 206, such that an adjustment of the frame element 204 relative to the frame element 202 also causes an adjustment of the frame element 206. In the present case, the coupling section 230 has an extension which engages in a corresponding recess of a coupling section 232 of the frame element 206. The frame member 204 extends from its end 226 to its end 228 out initially bulging and then tapering. The frame member 204 has a circumferential spar 234 which forms a profile contour. The spar 234 is stabilized with ribs 236. The frame member 204 has a hinge connection 222 for hinged connection with the frame member 202. The frame member 204 has a main extension plane in which the spar 234 and the ribs 236 extend. The axis of the hinge 222 is oriented orthogonally to the main plane of extension. To form the hinge 222 an opening or a pin is provided on the frame member 204.

The frame member 206 has a needle-like shape. An end 238 of the frame element 206 facing the profile nose 210 has a coupling section 232. The coupling section 232 serves for a kinematic coupling with the Frame member 204, such that an adjustment of the frame member 206 relative to the frame member 202 also causes an adjustment of the frame member 204. In the present case, the coupling section 232 has a recess into which a corresponding extension of the coupling section 230 of the frame element 204 engages. One end 240 of the frame member 206 forms the profile trailing edge 212 of the frame means 200 and thus the airfoil profile. The frame member 206 extends from its end 238 to its end 240 towards tapered. The frame member 206 has lateral uprights 242, 244 which form a profile contour. The spars 242, 244 are stabilized with ribs 246. The frame member 206 has a hinge connection 224 for hinged connection with the frame member 202. The frame member 206 has a main extension plane in which the spars 242, 244 and the ribs 236 extend. The axis of the hinge 222 is oriented orthogonally to the main plane of extension. To form the hinge 222 an opening or a pin is provided on the frame member 206.

The frame elements 202, 204, 206 form with their profile contours a profile contour of the frame device 200. In this case, a transition from a profile contour of a frame element to a profile contour of another frame element runs so steadily that the sail surfaces at least approximately flush against the profile contour. In the present case, the spars of the frame elements 202, 204, 206 have a rectangular cross-sectional area with an edge length of approx. 20-40 mm, in particular approx. 30 mm, x approx. 10-30 mm, in particular approx. 20 mm. The ribs of the frame members 202, 204, 206 have a smaller cross-sectional area. Transitions between spars and ribs and between ribs are made rounded in the present case with radii. This results in a favorable force curve. It spikes are avoided. A load capacity is improved.

The frame member 202 has an opening 248. The frame member 204 has an opening 250. In the openings 248, 250, a mast may be included. The frame 200 may be fixed to the openings 248, 250 on a mast. The mast is received in the openings 248, 250 with play. The Frame device 200 is thus limited relative to the mast displaced. The frame device 200 is thus pivotable about the mast. The openings 248, 250 overlap such that even with an adjustment of the frame means 200, in particular the frame members 202, 204 to each other, a mobility of the frame means 200 is maintained relative to the mast.

Fig. 3a 1 shows a frame device 300 of a profile sail device, such as a frame device 114 of a profile sail device 100 according to FIG Fig. 1 with three frame elements 302, 304, 306 and sail surfaces 308, 310 in a first operating position. A second operating position of the frame device 300 is in Fig. 3b shown. Fig. 3c shows the frame means 300 in a neutral middle position between the first operating position and the second operating position.

In the in Fig. 3a shown first operating position, the frame means 300 forms a wing profile, in which the sail surface 308 is an inflatable front and the sail surface 310 forms a back. In operation of a sailing craft, the sail surface 308 is typically on the windward side and the sail surface 310 is on the leeward side. The frame member 302 has a profile contour 312 associated with the sail surface 310 and a profile contour 314 associated with the sail surface 308. The frame member 304 has a profile contour 316 associated with the sail surface 308 and a profile contour 318 associated with the sail surface 310. The frame member 306 has a profile contour 320 associated with the sail surface 308 and a profile contour 322 associated with the sail surface 310. In the first operating position, the profile contour 316 of the frame element 304 and the profile contour 320 of the frame element 306 form a profile contour of the frame device 300 for the sail surface 308. In the first operating position, the profile contour 312 of the frame element 302 forms a profile contour of the frame device 300 for the sail surface 310 Sail surfaces 308, 310 are circumferentially against the profile contour of the frame device 300.

In the in Fig. 3c shown second operating position, the frame means 300 forms a wing profile, in which the sail surface 310 is an inflatable front and the sail surface 308 forms a back. In an operation of a sailing vehicle the sail surface 310 is usually on the windward side and the sail surface 308 on the leeward side. In the second operating position, the profile contour 318 of the frame element 304 and the profile contour 322 of the frame element 306 form a profile contour of the frame device 300 for the sail surface 310. In the first operating position, the profile contour 314 of the frame element 302 forms a profile contour of the frame device 300 for the sail surface 308 Sail surfaces 308, 310 are circumferentially against the profile contour of the frame device 300.

In the in Fig. 3b shown a neutral center position, the frame means 300 forms a symmetrical profile contour. In this middle position, the sail surfaces 308, 310 are not circumferentially against the profile contour of the frame device 300. In particular, in a middle section lying between the profile nose 324 and the profile trailing edge 326, the sail surfaces 308, 310 are not in contact with the profile contour of the frame device 300. At the profile nose 324 and at the profile trailing edge 326, the sail surfaces 308, 310 are also in the center position on the profile contour of the frame device 300.

In Fig. 3b It can be seen that the sail surfaces 308, 310 are spaced apart from each other in a defined manner. This is accomplished with a sail surface retainer 308, 310 having a plurality of retaining elements, such as 328. The holding elements 328 each have a piece of rope and a piece of pipe. The tube piece is located on the inside of the sail surfaces 308, 310 and defines a distance corresponding to its length of the sail surfaces 308, 310 from each other. The rope piece is guided in the pipe section and connected to both the sail surface 308 and the sail surface 310 tensile. Retaining elements that are closer to the profile nose 324 are longer than holding elements that are closer to the profile trailing edge 326. The holding elements extend approximately orthogonally to the sail surfaces 308, 310.

Fig. 4 1 shows a frame device 400 of a profile sail device, such as a frame device 114, according to a profile sail device 100 Fig. 1 , with cable operation for adjustment in isometric view. The frame device 400 has three frame elements 402, 404, 406. The cable operator has two ropes 408, 410. The cable 408 is connected to the frame member 404 at one of the profile trailing edge 412 facing end portion connected to a profile contour 414 facing side region tensile strength and initially guided on an upper or lower side of the frame means 400 transverse to a longitudinal axis of the frame means 400 and transverse to the pivot axes 416, 418. In a further course, the cable 408 is guided through a cable guide in the frame element 402 to the upper or lower side of the frame device 400. In a further course, the rope 408 becomes an in Fig. 4 not shown mast and along this guided in the direction of a mast base. The cable 410 is connected to the frame element 404 at an end region facing the profile trailing edge 412 in a tension-proof manner on a side region facing the profile contour 420 and initially on an upper or lower side of the frame device 400 transverse to a longitudinal axis of the frame device 400 and transverse to the pivot axes 416, 418 guided. In a further course, the cable 410 is guided through a cable guide in the frame element 402 to the upper or lower side of the frame device 400. In a further course, the cable 408 is guided to the mast and along it in the direction of a mast base.

With the ropes 408, 410, the frame device 400 is adjustable between the first operating position and the second operating position. A pulling operation of the cable 408 causes an adjustment of the frame device 400 in the first operating position. The end of the cable 408 fastened to the frame element 404 in a tension-resistant manner is pulled in the direction of the cable guide in the frame element 402 until the attachment point of the cable 408 to the frame element 404 lies approximately above the cable guide in the frame element 402. At the same time takes place by means of the kinematic coupling 422 between the frame member 404 and the frame member 406 entrainment of the frame member 406. The frame members 404, 406 pivot in opposite directions. With the cable 408, the frame device 400 can be fixed in the first operating position. A pulling operation of the cable 410 causes an adjustment of the frame device 400 in the second operating position. In this case, the end of the cable 410 fastened to the frame element 404 in a tensile-resistant manner is pulled in the direction of the cable guide in the frame element 402 until the attachment point of the cable 410 to the frame element 404 is approximately above the cable guide in the frame element Frame element 402 is located. At the same time takes place by means of the kinematic coupling 422 between the frame member 404 and the frame member 406 entrainment of the frame member 406. The frame members 404, 406 pivot in opposite directions. With the cable 410, the frame means 400 can be fixed in the second operating position. In another application, alternatively or additionally, cables of the cable actuation may be connected to the frame element 406 in a tension-proof manner, so that a pulling actuation first effects an adjustment of the frame element 406. In another application, actuating rods may alternatively or additionally be used. With the operating rods, a pulling operation or a pressure operation can take place.

Fig. 5 shows frame devices 500, 502 of a profile sail device, such as frame device 114 of a profile sail device 100 according to FIG Fig. 1 , in the folded state with salvaged profile sail device. The sail surfaces may be detached and removed from the frame assemblies 500, 502. The frame means 500 can be stacked one above the other. As in Fig. 5 As can be seen, the holding elements, such as 504, are arranged on the frame devices 500, 502.
