Definitions
- the invention relates to a boom, in particular a rig for a wind surfboard with two spars, at the rear end of which the sail is fastened to an attachment point, the attachment point being adjustable in its distance from the rear end of the boom by an adjusting device which can be actuated manually by transmission means one of which means of transmission ends on one spar and the other ends on the other spar.
- the user of a wind surfboard sets the tension of the sail before the trip, that is, he trims the sail by placing it at the lower end of the sail as well as at the rear end of the sail opposite those arranged there
- CONFIRMATION COPY Fastening points fastened the sail with the desired tension. This sailing tension can then no longer be changed while driving.
- the object of the invention is to improve a boom and in particular a rig so that the sail can still be easily trimmed by the user even while driving and trimming on one side does not interfere with trimming on the other side.
- fastening point is movable by the adjusting device between two or more fixed positions, in particular locking positions.
- the adjusting device have a lifting or pulling mechanism, which assumes a subsequent rest position with a different pull position after each actuation.
- a control mechanism in particular a lifting or pulling mechanism, can be attached to the spar, by means of which the transmission means can be actuated.
- a particularly simple and safe construction is provided if the mechanics have a curved track, cam track and / or toothed track.
- the mechanism can have a rotatable sleeve that is toothed on the end face.
- the transmission means have a cable pull, a Bowden cable, hydraulic means or pneumatic means.
- the transmission means can also end on the spar on a swivel or twist grip.
- the adjusting device has a one-sided locking mechanism, in which the locking part engages in particular a pawl in the recesses of a movable part, in particular a gear wheel, which determines the position of the fastening point.
- FIG. 2 shows a detail from FIG. 1 at the rear end of the boom
- Fig. 3 is an illustration of the control mechanism or pull mechanism on the spar
- Fig. 4 shows two alternative designs of Steuer words. Train mechanics.
- Fi. 5 shows the device according to FIG. 4 at the start of the train on one of the cable pulls 8
- FIG. 6 shows the device according to FIG. 4 at the end of the train on one of the cable pulls 8.
- the rig of a wind surfboard has a mast with a mast base, a sail and a boom 1, which laterally forms two spars 2. At the front end 3 of the boom this is attached to the mast and the rear end 4 is pivotable about the mast.
- the sail not shown, is attached to the mast foot, at the rear end 4 of the spar 2 and at the upper end of the mast.
- the attachment point 5 of the sail at the rear end 4 of the boom 1 has an adjusting device 6, which enables a different trim of the sail during the journey and can be remote-controlled by hand from both spars 2.
- transmission means 8 are arranged between the adjusting device 6 and the control mechanisms (pulling mechanism, in particular manual twist grip) attached to the spars 2, which in the exemplary embodiment are cable pulls.
- the control mechanism 7 on the spar 2 can be a simple pivotable handle or, as in the exemplary embodiment, a hand grip with a toothed sleeve 9 . which can be rotated by hand relative to a correspondingly toothed ring 10, so that the sleeve 9 lifts off from the ring 10 during rotation, in order to secure it to the sleeve To tension cable 8 and to transmit this tensile force to the adjusting device 6.
- the adjusting device 6 which is fastened to the end of the rear end 4 of the boom, has a cylindrical tension part (bolt) 11, at one end of which there is an eyelet 12 which forms the fastening point for the sail.
- the end of the cable 8 is fastened to a toothed ring 13 which, when actuated by the cable, is moved against a toothed sleeve 14 which is rotatably mounted on the pull part 11. With each train through the control mechanism 7 via the cable 8 on the ring 13, the sleeve 14 is always rotated by one tooth in the same direction. The direction is maintained in that the teeth are sawtooth-shaped both in the control mechanism 7 and in the adjusting device 6.
- the sleeve 14 has, on the side facing away from the ring 13, a curved path 15, on which a bolt 16 projecting radially on the pulling part 11 bears on one or on diametrically opposite sides.
- the cam track 15 alternately has higher and lower recesses 17, so that the bolt or bolts 16 alternately lie once in the higher recesses, once in the deeper recesses, and thus the pulling part 11 is once further outwards and at other times further inwards, so that the sail is tensioned more in one position and less tensioned in the next position.
- the adjusting device 6 can also be constructed differently, since the most varied lifting and pulling mechanisms are conceivable.
- the control mechanism 7 can be constructed in a wide variety of ways.
- a transmission means in the form of a cable transmission by Bowden cable, hydraulic means or pneumatic means.
- the adjusting device 6 can thus in particular also have a cylinder-piston unit.
- the adjusting device 6 has a one-sided tooth ratchet with a gearwheel 18, two pawls 20 snap into place behind the sawtooth-shaped teeth 19 thereof.
- a shaft 21 is coaxially attached to the gearwheel, on which a rope 26 can be wound, at the other end of which the sail end is fixed.
- a pawl 20a is articulated on a lever 22 which can be pivoted against spring force or on a wheel 23 which can be rotated against spring force, on which the two transmission means 8 are fastened on the outside, so that by pulling on the transmission means the gearwheel 18 around one tooth further turned and the sail is further stretched.
- the lever or the wheel form a translation of the tensile force generated.
- the transmission means 8 is in the form of a rope in a groove in the circumference of the wheel 23.
- a second pawl 20b is provided which engages in the same gear 18 and is articulated on the housing or stand of the device. The second pawl holds the gear against turning back when the first pawl is disengaged.
- a toothed rack or a friction lock can also be arranged instead of the gearwheel. If the control mechanism 7 on the spar 2 is to be used for the device according to FIGS. 4 to 6, the stroke generated by the teeth must be large enough to release the adjusting device, or a larger pull must be generated by another device or in another way .
