Definitions

  • the present invention relates to a supporting frame for a hand-supported sailing rig according to the preamble of patent claim 1 and a sailing rig provided with such a supporting frame.
  • a sailing rig with such a support frame is also called “ingsail” and can be used, for example, by
  • Skaters or roller skaters are used who use this sailing rig similar to a windsurfer to use the wind power for propulsion.
  • the rig has a support frame with two mast tubes, which are set up arrow-like against one another in the triggered state and are connected via a joint device. Elastic extensions are formed on the end sections of the two mast tubes, which act similarly to a batten to tension the sail.
  • a cross tube is articulated in the joint area between the two mast tubes, which extends from the articulation device to the leech of the sail.
  • the cross tube is supported by V-shaped supports on the respective mast tubes.
  • the free end section of the cross tube is connected to the leech for tensioning the sail.
  • This sailing rig is held by the skater or roller skater without support, so that the holding forces to be exerted by the user are comparatively large.
  • Another disadvantage of the known construction is that the support structure for supporting the cross tube and the articulation of the cross tube and connection of the two mast tubes by means of the articulated device requires a great deal of technical equipment, since a large number of components, such as connecting sleeves and articulated connections must be provided in order to couple these components with the required strength. Due to the complexity of the construction, it also takes some practice and time to bring the familiar sail from the folded transport state to the ready-to-sail state.
  • a rig for skis is known from EP 0152306B1, which is provided with receptacles for the mast end. Such a construction is not intended for use with ice skates or roller skates.
  • the invention has for its object to provide a sailing rig and a support frame for a hand-supported sailing rig, which is easy to handle with minimal equipment effort.
  • the end sections of a mast are provided with support devices so that the rig can be supported on the foot, skate or roller skater or elsewhere on the operator during sailing and the holding force is therefore not entirely dependent on the arms of the user - can be brought.
  • the support via one of the two end sections also allows gusts to be weathered in a simple manner, since only the hand located closer to the leech has to let go, so that the rig can blow through an axis running through the support point and therefore no excessive wind pressure, which in unfavorable cases can lead to the fall, is transmitted. Since the support is on the body of the operator, no recordings on the skates or other sports equipment need to be provided.
  • the U-shaped or V-shaped structure of the mast is formed by a central section with adjoining curved end parts.
  • the end parts have a certain intrinsic elasticity, but they can have approximately the same bending strength as the central section of the mast.
  • a particularly good flow against the rig is achieved when the central section is curved in a circular arc, the radius of curvature of the central section being greater than that of the two end sections.
  • the radius of curvature of the central section being greater than that of the two end sections.
  • other curvature geometries such as elliptical curvatures, etc., can also be provided.
  • a particularly simple tensioning of the sail and safe handling of the sailing rig can be achieved if the holding device is designed with two tree struts converging towards the leech. These tree struts are hinged to the central section of the mast with their front ends remote from the leech.
  • the V-shaped construction of the holding device enables the operator to hold the rig below the sail pressure point, so that the sail top can pass through the wind pressure away from the driver and the mast with its support device is pressed against the body, thus ensuring optimal three-point support of the rig.
  • the central section is provided with an articulated device which divides it into an upper and a lower mast central part.
  • a particularly stable and simply constructed joint device is obtained if it has a base part which is arranged coaxially to the mast and has two joints which are spaced from one another and to which the first mast middle part and the second mast middle part are articulated.
  • the mast can also be subdivided by means of a plug connection or a similar construction.
  • the support in the ready-to-sail state is particularly stable if the base part has a support shell at each end section, which overlaps with the respectively associated mast center part, so that this is supported by the support shell.
  • the rear end sections of the tree strut are advantageously releasably connected to one another.
  • the storage space of the folded sail is minimal when the two end parts are also detachably coupled to the central section of the mast.
  • the sailing rig is particularly easy to handle if a support strut is arranged on the free ends of the mast and extends away from the mast. This support strut can then be supported, for example, on the user's instep.
  • an end fitting is preferably provided, which enables tensioning of the sail leech.
  • the pivot axes of the articulation device and the articulation of the tree struts on the mast are selected such that the mast parts and the tree struts run approximately parallel to one another in the folded state.
  • the curvature and the length of the two mast end parts and, if appropriate, of the mast center section are preferably carried out in such a way that a connecting line between the two mast ends roughly intersects the sail pressure point.
  • Figure 1 is a view of the rig in ready to sail condition
  • FIG. 2 shows a detailed side view of the rig from FIG. 1 in the folded state
  • Figure 3 is a side view of a mast end section
  • FIG. 4 the aft end of a holding device of the rig from FIG. 1;
  • Figure 5 shows an alternative connecting link, via which the mast can be dismantled into at least two parts and
  • Figure 6 shows the link in the folded state.
  • Figure 1 shows a view of a support frame 2 made of aluminum tube of a sailing rig 1, to which a dashed line 4 sail 4 can be attached.
  • the support frame 2 according to the invention has a mast 6 and a holding device 8 which extends from the mast 6 to the leech 10 of the sail.
  • the mast 6 has a central section 12 which is curved with a radius of curvature R in the exemplary embodiment shown.
  • the two upper and lower end sections of the mast 6 in FIG. 1 are also curved in a circular arc, the radius of curvature r being smaller than that of the central section 12.
  • These end sections are formed by tubular end parts 14, 16 which are suitably connected to the Middle section 12 are connected.
  • a possible connection can be made, for example, by a push pin system or by inserting a tapered section of the end parts 14, 16 into a corresponding receptacle in the central section 12.
  • the holding device 8 has two tree struts 18, 20 arranged in a V-shape with respect to one another, which are articulated on the central section 12 of the mast 6 with their end sections which are on the left in FIG.
  • the other end section of the tree struts 18, 20 is joined via a connecting device 24, the construction of which is explained below. - 1 -
  • the sailing rig 1 shown in FIG. 1 has a structure symmetrical to a central axis 3 (parallel to the plane of the drawing in FIG. 1).
  • the upper tree strut 18 is made slightly longer than the lower tree strut 20, so that the former extends to the leech 10 or beyond.
  • an end fitting 26 is provided, via which the leech 10 can be subjected to a tensile force in order to adjust the sailing depth.
  • the central section 12 of the mast 6 is formed with an articulation device 28 which enables the mast 6 to be folded up.
  • the structure of this joint device 28 is shown in FIG. 2.
  • FIG. 2 shows a side view in the articulation device 28 in FIG. 1. Accordingly, it has a tubular base part 30, to which two mast center parts 38, 40 are articulated. The two mast middle parts 38, 40 and the articulation device 28 together form the middle section 12.
  • the two mast middle parts 38, 40 are shown in FIG. 2 in the folded position, the stretched position corresponding to FIG. 1 is indicated by broken lines.
  • the jacket section in the region of the end sections of the base part 30 is cut out in the longitudinal direction, so that two support shells 32, 34 are formed which overlap with the corresponding end sections of the mast middle parts 38, 40 in the extended position (dashed).
