Definitions
- the invention relates to a sail sheeting or trimming device, in particular for wind surfing or dinghy sails, comprising a line for interconnecting a fix point, e.g. a clew, on the sail and a force transmitting device, whereby the line can be stretched manually.
- a fix point e.g. a clew
- sail sheeting devices are line blocks and winches, often arranged in combination with clam- ping devices, e.g. so called clam-cleats, so that the sheet line can be stretched manually under force amplification and be secured in a stretched condition. Similar devices ar also used .for fine adjustment or trimming various parts of a sail, e.g. for adjusting its curvature or belly to the actual wind conditions.
- the background of the invention is a desire to enable a fine control of the stretching of the sail while sailing by means of a device which is easy to operate and easy to reach. This is achieved by a device having the features stated in claim 1
- the device can also be used in other applications than wind surfing and dinghy sailing, e.g. for trimming shrouds and stays in a sailing rig.
- the force transmitting device is designed as a rotary handle, the latter can serve two purposes at the same time, namely as a holding means and a self-checking sail sheeting means.
- Fig. 1 shows a wind surfing sailor on a sailing board provi- ded with a sheeting device according to the invention
- Fig. 2 shows a central longitudinal section through a handle rotatably arranged on a bracket and included in the inventiv sheeting device;
- Fig. 3 shows a section along the line III-III in Fig. 2;
- Fig. 4 shows an alternative embodiment comprising a rotary handle forming an integral portion of the loop-formed boom.
- a sailor is shown sailing on a board having a conventional mast 1, a sail 2 and a loop-formed boom 3. Furthermore, according to the invention, a special sheeting device is fastened to the boom 3.
- the sheeting device consist of a rotary handle 4a, 4b attached to each boom half 3a, 3b, which i.handle is connected to a sheeting line 5a, 5b in such a way that the sheeting line is stretched or slacked when the handle is turned manually by the sailor.
- At least one of the sheeting line portions 5a, 5b (in the shown example both portions) is conncected to a line 8a, 8b extending axially into the handle by means of a loop and hook 9a, 10a and 9b, 10b respectively, or corresponding simple coupling means.
- one and the same sheeting line 5a, 5b is thus drawn from one of the coupling means 9a, 10a of the handle 4a via a hole 11a in an after boom fitting 11 through the eye of the clew 7, via another hole lib in the boom fitting 11 to the coupling means 9b, 10b of the other handle 4b.
- the configuration of the line at the boom fitting 11 and the clew 7 can, of course, be modified in many different ways by means of pulleys or the like.
- the sheet li e portions 5a, 5b can also be separately fastened to the clew 7, which would make it necessary to give away the respective sheet line portion somewhat before one goes to windward and sails on the other tack.
- a bracket 12 of e.g. aluminum or other light and corrosion resistant construction material, is at one end formed with two complementary halves 13a, 13b, which by means of a screw or some other clamping device can be secured in a desired position on the boom 3 (dashed) .
- the bracket 12 is connected to a guiding means 14 extending at right angle therefrom(thus, in parallel to the boom 3 or the like) in the form of two parallel and mutually separated guide mem ⁇ bers 14a, 14b each having a cross-section (Fig. 3) formed as a circular segment.
- the guiding means 14 is suitably formed integrally with the bracket 12 but can also be rigidly connected thereto in another way.
- the guide members 14a, 14b form between themselves a centrally longitudinal cavity, in which a screw member 15 is disposed.
- the screw member is dimensioned so as to be slidingly guided and displaced axially between the guide members without being rotated about the longitudinal axis, along which the line 8 extends through a hole 16 in the bracket 12 and through a hole 17 situated in registry therewith in the screw member 15.
- the hole 17 is somewhat expanded in the portion of the screw member 15 facing away from the bracket 12 for receiving an end knot on the line 8, as shown in Fig. 2.
- the screw member 15 is provided with an external trapezoid thread which engages with a corresponding internal trapezoid thread at the inside of a rotatable sleeve 18, which forms the handle 4 of the sheeting device.
- the sleeve 18 is kept axially secured between the bracket 12 and a locking ring 19 fastened to the free solid end of the guiding means 14, the locking ring being fixed by means of a locking screw 20.
- Both the handle sleeve 18 and the screw member 15 are suitably made of a thermoplastic material of low friction, such as polyamide.
- a thermoplastic material of low friction such as polyamide.
- FIG. 4 An alternative embodiment of the handle device is shown in Fig. 4, wherein the handle sleeve 18'is integral with the boom 3. A portion of the tubular boom 3' is cut away
- a connecting member serving as a guide'for a screw member (not shown) and the surrounding, rotatable handle 18'.
- the guide, the screw member and the handle sleeve have substantially the same design and function as sho in Figs. 2 and 3.
- the connecting member is fastened to the boom portions 3' by means of internal tube sections 21, 22 being secured by rivets 23.
- the left tube section 21 has a radial flange 24, whereas a locking ring 19' is fixed by means of a looking screw 20' onto the right tube section.
- the rotary handle sleeve 18' is kept axially fixed between the flange 24 and the locking ring 19*.
- the sheet line 8 runs inside the boom 3' and suitably runs inside the boom all the way to the after fitting or the like.
- the one shown in Figs. 2 and 3 has the advatage that the handle 4 can be mounted at a desired • position along the boom 3.
- the embodiment according to Fig. 4 is advantageous in that the boom 3' does not have any protruding portions and the sheet line 8" extends hidden inside the boom.
- the device according to the invention can be modified in several ways.
