As a skeleton line, the line lying in the cross-section of the profile sailing device 100 exactly between the sail surfaces 102, 104, designated. The profile contour of the profile sailing device 100 is thus symmetrical about the skeleton line.

The longitudinal spars 308, 310 and the transverse spars 314 define convex quadrilaterals, such as 316, each having four corners and two intersecting diagonals. The tension members 302, 304 each have two ends. The tension members 302 are secured with their ends in opposite corners of the squares 316. The tension members 304 are secured with their ends in opposite corners of the squares 316. The tension members 302, 304 are arranged crossing each other.

When adjusting the frame member 300, the squares 316 deform parallelogram. The lengths of the diagonals change. When the frame member 300 is displaced to an end position, one diagonal of the squares 316 has a maximum length and the other diagonal has a minimum length. The maximum lengths of the diagonals are determined by the lengths of the Tension elements 302, 304 limited. When the frame element 300 is adjusted to an end position, depending on the end position, the tension elements 302 or the tension elements 304 are tensioned, so that further adjustment of the frame element 300 is prevented. In the present case, pliable cables serve as tension elements 302, 304. The shorter diagonal associated pulling elements 302, 304 can thus sag without tension. Incidentally, in addition to particular Fig. 2 and Fig. 3 and the associated description.

Fig. 5 shows an adjustable frame member 400 of frame means with adjustable tension members 402, 404 to limit maximum lengths of diagonals.

The tension elements 402, 404 each have a cable section 406, 408 with a fixed length and a length-adjustable tension section 410, 412. The tensile sections 410, 412 can each be mechanically, electromechanically, pneumatically and / or hydraulically adjustable in length. Thus, the maximum lengths of the diagonals are adjustable. Thus, the end positions of the frame device 200 are adjustable. Thus, a shape of the frame device 200 is adjustable in the end positions. Incidentally, in addition to particular Fig. 4 and the related description.

Fig. 6 11 shows a detail view of a corner 500 of a quadrilateral 506 delimited by longitudinal beams, such as 502, and transverse beams, such as 504, with a tension member 508. The adjustable frame member 510 has connecting elements, such as 512. The connecting elements 512 serve to connect the longitudinal bars 502 and the transverse bars 504 and for fastening the tension elements 508. The connecting elements 512 each have fixed sections for receiving the longitudinal bars 502 and the transverse bars 504. The connecting elements 512 each have a flexible section arranged between the fixed sections. The connecting elements 512 each have eye-like fastening points, such as 514, for fastening the tension elements 508. The connecting element 512 is arranged at a junction between the longitudinal spar 502 and the transverse spar 504 and serves to secure two Tension elements, such as 508, two adjacent squares, such as 506. Incidentally, in addition to particular Fig. 2-5 and the related description.

Fig. 7 shows a detailed view of a frame means 600 for a profile sail device with an adjustable frame member 602, two on the adjustable frame member 602 displaceably arranged fixed frame members 604, 606 and control cables 608, 610th

In the illustrated end position, the operating cable 608 is actively pulled in the direction of arrow a and the operating cable 610 inactive. The operating cable 608 is guided by means of two rollers 612, 614 on the longitudinal spar 616 of the frame element 602. The frame member 604 has a guide 618 on which the operating cable 608 is guided. The operating cable 608 is connected at one end to the frame member 606 tensile. Pulling the actuation cable 608 in the direction of the arrow a causes an opposing displacement of the frame members 604, 606 such that the frame members 604, 606 move toward the longitudinal spar 616 of the frame member 602. Likewise, the operating cable 610 is guided on the longitudinal spar of the frame element 602, which is not visible here. Pulling the operating cable 610 in the direction of arrow b causes an inactive operating cable 608 an opposite displacement of the frame members 604, 606 in the opposite direction such that the frame members 604, 606 shift to the not visible here longitudinal spar of the frame member 602 out. Incidentally, in addition to particular Fig. 2-5 and the related description.

Fig. 8 shows a longitudinal spar 700 of an adjustable frame member with C-profile and attached sail surface 702 in a sectional view. The longitudinal spars, such as 700, each have a kederartigen round rod 704 and a keder rail-like profile bar 706 with a slot-shaped opening 708 on. The round bar 704 is internal and the profile bar 706 is located outside. The round rod 704 has a larger diameter than the slot-shaped opening 708. The sail surface 702 has sewn tabs with a tab portion 710 for passage through the opening 708 and a Receiving portion 712 for the rod 704 on. The sail surface 702 is attached to the longitudinal spar 700 by means of the welt flap. The profile bar 706 has in the present case a C-like profile. Incidentally, in addition to particular Fig. 1-3 and the related description.

Fig. 9 shows a longitudinal spar 800 of an adjustable frame member with Ω profile and attached sail area in a sectional view. In the present case, the profile bar 802 has an Ω-like profile. Incidentally, in addition to particular Fig. 8 and the related description.

Fig. 10 shows a frame means 900 for a profile sailing device with an adjustable frame member 902 and two on the adjustable frame member 902 displaceably arranged fixed frame members 904, 906, wherein the solid frame member 906 is made in two parts. The solid frame member 906 is associated with the profile trailing edge 908. The fixed frame member 906 has a first part 910 and a second part 912. The first part 910 is arranged on the profile nose side. The second part 910 is arranged behind the profile edge. The first part 910 and the second part 912 are supported by a pivot bearing 914. The second part 910 forms with one end the profile trailing edge 908.

To operate two operating cables 916, 918 are provided. The operating cables 916, 918 are guided on the adjustable frame member 902, the fixed frame members 904, the first part 910 of the fixed frame member 906, and the second part 912 of the fixed frame member 906 in such a manner that a pulling force of the operation cable 916 is adjusted Direction of an end position and a tensile force of the operating cable 918 causes an adjustment in the direction of another end position. In this case, there is a displacement of the fixed frame members 904, 906 in opposite directions and a displacement of the first part 910 and the second part 912 in the same direction. An adjustment in the direction of the one end position is different than an adjustment in the direction of the other end position. In an adjustment direction, the fixed frame members 904, 906 by means of an actuating cable, starting from a deflection on a longitudinal spar 920 with their ends facing each other pulled the longitudinal spar 920 out. In the other direction of adjustment, an operating cable makes an angle between the fixed frame members 904, 906 via a lever system. The longitudinal spar 920 follows the adjustment guided by sliding guides.

By means of the second part 912 of the fixed frame element 906, an improved defined setting of the profile trailing edge 908 is made possible. Incidentally, in addition to particular Fig. 2 and Fig. 3 and the associated description.
