Definitions

  • the invention relates to a standing glider according to the preamble of claim 1 or claim 6 or. of claim 8.
  • Stand-up sailors which can be adapted to changing wind strengths and to the different abilities of the users.
  • the sail is attached to a large tree and is designed to be gathered.
  • the large tree has several holding straps on both sides over part of its length.
  • the sail is divided into two parts of the sail, which are guided in grooves or rails on the top and bottom of the boom.
  • the mast is provided with a longitudinal groove in which the luff of the upper and lower sail section run. If the sail area is to be reduced, the lower part of the sail can be removed first. But both sail parts can also be gathered.
  • this floor glider is not only structurally complex and difficult to handle in its changeability, but also difficult to steer.
  • the sail is rotatably connected to the rotating mast.
  • the mast In order to change the size of the sail area, the mast has to be turned by hand, while at the same time the tension rope has to be wound onto a capstan mounted on the mast. Since at the same time the mast has to be turned and the tensioning rope has to be wound onto or from the spill, the adjustment of the sail, especially during sailing, is cumbersome and tedious. In addition, the handling must be carried out on the mast; it then presents considerable difficulties in keeping the boom sufficiently secure during the adjustment.
  • the sail In another known standing glider (DE-A-3 031 724) the sail is not wound on the mast, but on a reeling mast rotatably mounted on the mast. It is rotated against the force of two torsion springs which are provided at the upper and lower ends of the furling mast when the sail is unwound. Instead of the torsion springs, a motor can also be used to turn the reel mast.
  • the additional furling mast and its storage on the mast lead to a considerable design effort of the standing glider.
  • the handling for adjusting the sail is also cumbersome and complicates the steerability of the standing glider, because the handling - turning the reel mast and loosening and clamping the tension cable - must be carried out on the mast.
  • the invention has for its object to design the generic standing glider, which has only a single sail, so that the size of the sail area can be changed by the user in a simple manner with a structurally simple design, without adversely affecting the steerability of the standing glider is.
  • the sail is wound onto the mast itself or unwound from it. Since the mast is under the force of the return spring, the sail can be easily unwound or wound up. Since the tensioning cable can be actuated at the end of the boom facing away from the mast, one hand of the user is in the area of the mast and the other hand is in the area of the tensioning element arranged. This allows the glider to be steered properly and safely during the adjustment process. As a result of the two return springs on the mast and at the end of the boom, the sail can be wound up and unwound without difficulty, so that the size of the sail area can be easily changed while sailing.
  • the return spring is tensioned or relaxed when the mast is rotated to wind up and unwind the sail.
  • the sleeve protects the return spring from premature wear or damage. Since the sleeve is provided on the rotary bearing of the standing glider, there are very favorable leverage and force ratios when turning the mast, so that the sail can be effortlessly wound up or unwound while sailing.
  • the tensioning rope can be actuated from the end of the boom facing away from the mast, so that the user has one hand in the area of the mast and the other hand in the area of the boom end during the adjustment process, so that the standing glider can be steered properly when adjusting the sail .
  • the mast consists of two mast parts which are connected to one another by the pivot bearing for the boom.
  • the mast parts are rotated in relation to the pivot bearing when the sail is adjusted, causing the two return springs be excited or relaxed.
  • the sail can therefore be effortlessly wound up or unwound from the mast. Since the return springs are provided in the area of the pivot bearing, favorable leverage and force ratios result in turn when the mast is turned, which considerably facilitate the adjustment of the sail.
  • the user can hold the boom again in the area of the mast and at the end of the boom, so that the standing glider can be steered perfectly.
  • the standing glider has a sail board 1, which is provided with a sword 2 and a stabilizing fin 3.
  • a mast 4 is pivotally and rotatably mounted on the sailing board 1.
  • a sail 5 is attached to the mast 4, the sail tip 6 of which is held on a boom 7. It is connected to the mast 4 in a known manner by means of roller bearings or ball bearings. 6 and 7, the sail tip 6 is connected to the boom 7 via a tensioning device 8. It has two curved arms 9, 10, the so-called. Spar, between which the sail 5 runs.
  • the mast 4 is rotatably and pivotally connected to the sail board 1 at the lower end 11.
  • the connection between mast 4 and sailing board 1 is made via a ball joint 12, which allows the mast to be pivoted in all directions.
  • the sail 5 is wound on the mast 4 or unwound from it to change the sail area.
  • This spring load can be provided such that the mast 4 is spring-loaded in the winding direction at the maximum sail area (FIG. 1), so that after the tensioning device 8 is loosened, the sail 5 is automatically wound onto the mast 4.
  • the tensioning device 8 is arranged in such a way that it generates a counterforce that is opposite to the spring force, so that the sail 5 is held tensioned in the respective position.
  • the mast 4 is provided at the lower end 11 with a return spring 13. It is preferably housed in the mast so that it is protected against dirt and corrosion.
  • the mast 4 has a blind hole 14 at the lower end, into which an end piece 15 of the mast 4 projects.
  • a foot piece 16 is inserted into the sail board 1, with which the mast 4 is fastened to the sail board 1.
  • the end piece 15, which is inserted into the blind hole 14 of the mast 4 has a receptacle 17 for the return spring 13 at the free end.
  • a pin 18 engages in this receptacle 17, which is housed in the blind hole 14 of the mast and on which the end piece 15 is axially displaceably mounted.
  • the pin 18 can be rotatably mounted in the receptacle 17 of the end piece 15, but can also be connected to it in a rotationally fixed manner. In this case, the mast 4 rotates with the end piece 15 when the sail 5 is wound up. In the other case, the mast 4 rotates with the pin 18 in the receptacle 17 of the end piece 15.
  • a further return spring (not shown) is provided at the end of the boom 7 facing away from the mast 4.
  • the two return springs are preferably biased in opposite directions, so that the sail is under spring force during winding and unwinding.
  • a lock is provided for the return spring with which the spring force and thus the sail tension can be kept constant.
  • a lock is advantageously provided as a rotation lock, with which the mast can be locked against rotation in the desired position.
  • the mast 4 is telescopic due to the end piece 15 at the lower end. It can thus be adjusted in length to adapt to the body size of the user and / or the sail size.
  • the telescope training can of course also be provided at any other suitable location on the mast 4.
  • the sail 5 can be wound on the mast 4 in spite of the pivot bearing 19 for the boom 7 indicated in FIG. 3, the sail can be divided over its entire length or at least partially. 3 and 4, the sail 5 is designed to be divisible transversely to the mast 4, preferably perpendicular to the mast and parallel to the boom 7.
  • the sail 5 can be separated from the mast 4 and is provided with a releasable separation point 20 for this purpose. At maximum sail area (FIG. 1), this separation point 20 is closed, so that the full sail area is available for sailing. If, on the other hand, the sail area is to be reduced, the separation point 20 is opened to the extent that the sail area is to be reduced. The length of the separation point 20 determines the smallest sail area of the sail 5.
  • the length 21 of the separation point 20 (FIG. 1) and the length 22 of the sail 5 from the mast 4 to the sail tip 6 are selected so that the desired sail area when winding up the sail remains.
  • the length 21 of the separation point 20 is advantageously approximately one third of the length 22 of the sail 5. With such an aspect ratio, the sail area can be reduced by approximately half.
  • the sail area can be continuously changed and thus optimally adapted to the particular circumstances. It has proven to be advantageous to form the separation point 20 by a zipper. It is easy to handle, so that the sail surface can be easily adjusted while sailing.
  • a zipper or the like is advantageously used, the handle 23 of which, in a known manner, is provided on the underside with a hook-shaped tip which engages between the teeth of the zipper when the zipper is only partially open and thus prevents the zipper from being opened further.
  • a Velcro fastener instead of a zipper, a Velcro fastener, push buttons and the like can also be used.
  • the sail 5 is provided in the region of the end 24 of the separation point 20 facing the mast 4 with a cutout 25 so that the sail is not wound onto the pivot bearing 19 for the boom 7. As shown in FIG. 4, the sail is wound onto the mast 4 in the area above and below the pivot bearing 19, so that there is no risk that the sail 5 will be damaged or get caught on the pivot bearing 19.
  • the tensioning device 8 engages on the sail tip 6.
  • the tensioning device 8 is held on the boom 7 and can thus be operated comfortably by the user of the standing glider while sailing. It has a tensioning rope 26 which engages the sail tip 6 and can be tensioned with an actuating member 27 held on the boom 7.
  • a tab 28 is expediently provided on the sail tip 6, through which the tensioning rope can be guided.
  • the actuating member 27 is arranged in the transition region 29 between the two boom arms 9 and 10 and is formed by two pulleys 31 and 32 which can be rotated with a crank 30 and onto which the tensioning cable 26 can be wound.
  • the rope pulleys 31 and 32 are preferably sunk in the transition area 29 (FIG.
  • the pulleys 31, 32 sit on a shaft 33 which can be rotated with the crank 30.
  • channels (not shown in detail) are provided in the transition region 29 of the boom 7, through which the tensioning cable is guided to the sheaves which are separated from one another by an intermediate wall 34 penetrated by the shaft 33.
  • the crank 30 lies in the area above the transition area 29 and can be secured against rotation by a lock 35.
  • the crank 30 is provided with a foldable handle 36, which can be folded down from the position shown in FIG. 6 by 180 °.
  • a lock 35 for this handle 36 a recess is provided in the transition area 29 on the outside facing away from the sail 5, into which the folded handle engages.
  • the crank is secured in a structurally simple manner against unintentional rotation.
  • the tension of the sail 5 cannot be released accidentally.
  • the separation point 20 is at the height of the boom 7 and parallel to it. If the sail area is now to be reduced, the user of the standing glider must first open the separation point 20 to the desired extent. Then it is only necessary to remove the handle 36 from the lock 35. As a result of the prestressed return spring 13, the mast 4 is now automatically rotated in the winding direction, the sail 5 being wound onto the mast 4 and the return spring on the side of the boom being tensioned. The user can easily control the winding speed by means of the crank 30 by holding it during the winding process and rotating it to the desired extent. As soon as the desired smaller sail area is set, the handle 36 is folded back into the recess 35, as a result of which the set position of the sail 5 is locked.
  • the tensioning cable 26 and thus the sail 5 are automatically tensioned.
  • the sail area can be increased again by releasing the locking device and merely turning the crank 30 and unwinding the sail 5 from the mast 4 against the force of the return spring 13.
  • the return spring on the boom side supports the unwinding process.
  • the height adjustability of the mast 4 nevertheless ensures that the sail 5, the mast and the handling of the boom can be adapted to different body sizes.
  • the mast 4 is only moved axially relative to the end piece 15 and in the respective axial position secured in a manner not shown.
  • the two pulleys 31, 32 only one pulley is sufficient.
  • one end of the tensioning cable 26 is fastened to the sail tip 6, while the other end of the tensioning cable is fastened to this sheave and is wound onto or unwound from the sheave upon rotation of the sheave.
  • a tensioning chain can also be provided, for which one or two chain wheels are required instead of the rope sheaves.
  • the sail 5 Since the sail 5 is axially immovable on the mast 4, a special shape of the vertically formed mast 4 or the sail 5 is unnecessary.
  • the sail For connection to the mast 4, the sail is only provided with a pocket 37 through which the mast projects. So that when changing the sail area the sail 5 is also taken along by the mast 4 in the winding direction, the sail pocket 37 is expediently clampable at the mast tip, at the lower end and at the level of the separation point 20 on the mast 4.
  • the pivot bearing 19 is formed in a conventional manner by a rope which is looped several times around the mast 4 and connected to the boom.
  • the friction between the mast and the rope is relatively large.
  • 8 and 9 show an embodiment in which the pivot bearing 19a ensures that the mast 4 rotates with little friction.
  • the pivot bearing 19a has a sleeve 38 which is attached to the boom 7 in the transition region 39 between the two arms 9 and 10. The sleeve 38 protrudes up and down over the boom (Fig. 8) and surrounds the mast 4 with little play.
  • two clamp-shaped clamping pieces 40 and 41 are provided, which are clamped on the mast 4 at both ends of the sleeve.
  • the sleeve 38 lies on the lower clamping piece 41, so that a certain amount of friction occurs at this point, but this is so small that it is practically insignificant.
  • an extremely low-friction pivot bearing for the mast 4 is achieved, so that the sail 5 can be easily adjusted to the desired sail area.
  • the total length of the pivot bearing 19a with the sleeve 38 and the clamping pieces 40 and 41 is so great that it can preferably be accommodated within the recess 25 (FIG. 3) of the sail. Otherwise, the standing glider is of the same design as in the previously described embodiment.
  • the embodiment according to FIGS. 10 and 11 differs from the embodiment according to FIGS. 8 and 9 in that the return spring 13b for the mast 4 is accommodated within the sleeve 38b.
  • One end 42 of the return spring 13b is fastened in the upper clamping piece 40 and the other end 43 in the lower clamping piece 41.
  • the return spring 13b is tensioned or relaxed.
  • the return spring in the lower end region of the mast 4 is omitted. Since the return spring 13b is accommodated in the region of the pivot bearing 19b, the lever and force ratios are much more favorable than in the embodiments in which the return spring is provided at the lower end of the mast.
  • the mast 4c is formed by two mast parts 44 and 45, which are connected to one another by an intermediate piece 46, which forms the pivot bearing 19c. It has a cylindrical middle part 47, which has the same outside diameter as the mast parts 44 and 45. As a result, the mast 4c does not have any shoulders or the like in the area of the pivot bearing 19c, so that no disturbances occur when changing the sail area.
  • the two end pieces 48, 49 of the intermediate piece 46 have a smaller outside diameter than the middle part 47, so that an annular space remains between the end regions of the mast parts 44 and 45 and in each of which a return spring 13c, 13c 'is accommodated.
  • One end of the return springs 13c, 13c ' is attached to the mast part 44 and 45 and the other end to the end pieces 48 and 49 of the middle part 7.
  • the two return springs 13c, 13c ' are biased in opposite directions, so that one return spring is effective when winding up and the other return spring is active when unwinding the sail 5.
  • a return spring is no longer required in the lower end region of the mast 4c.
  • the end pieces 48 and 49 of the middle part 46 are suitably rotatably connected to the respective ends of the mast parts 44 and 45.
  • FIG. 14 shows a simple mounting possibility for the mast 4 on the boom 7d.
  • the transition region 39d of the boom 7d is designed as a pivoting part which can be pivoted about an axis 50 lying parallel to the mast 4.
  • a circular opening 51 is provided for the mast 4, which is delimited in part by the pivotable transition area 39d and in part by the fixed part of the boom 7d.
  • the pivotable, partially circular transition region 39d is pivoted about the axis 50 in the direction of the double arrow 52 into the position shown in dashed lines in FIG. 14.
  • the mast 4 can then be inserted into the opening 51.
  • the transition region 39d is then pivoted back so that it encloses the mast 4.
  • the transition region 39d is then suitably locked on the remaining part of the boom 7d.
  • the beginner is given a device that is easy and simple to operate, offers a high level of security in changing weather and wind conditions, and enables everyone to achieve new, high-performance sports.
  • the sail area can be easily enlarged or reduced, for example from 6 sqm for a full sail to 3 sqm, i.e. to about half the sail area. This reduces the area exposed to the wind, so that when strong winds or gusts occur by reducing the size of the sail area, even the beginner can safely sail the floor glider back to the jetty or the beach.
  • the standing glider can be adjusted to different body sizes due to the length adjustability of the mast 4. But even the advanced can now optimally adapt the canopy to different weather and wind conditions.
