The invention relates to a device for adjusting the curvature of a boat sail with at least an elastic, flexible batten made of

is stiff, the curvature of the batten being adjustable in each case by means of a line held by a device.

Theory and experiment agree that the curvature of the boat sail is of great importance if it is to provide the highest propulsive thrust. However, the best results obtained in laboratory tests on sails cut from canvas and shaped into ideal shapes cannot be reproduced on real boat sails. The belly of the sail cannot be designed in the known ideal shape. The belly depends on the properties of the canvas, the tension of the traps and sheets, the rigidity of the mast and spars, and the direction and strength of the wind. Under these conditions, the belly is a result that can be maintained passively rather than actively, especially when sailing close to the wind.

Sails with elastically deformable battens of various structures are known which either simply serve to increase the rigidity of the sail or, in conjunction with other flexible elements, prevent creasing in the sail by unifying the curvature to a certain extent from top to bottom which the sail assumes under the influence of the wind. It has also been suggested. To provide sails with flexible battens, which are formed by articulated elements which are interconnected by e ^; ne line are connected, which standing under the influence of an adjustment device can be put under a more or less great tension. In one of the positions of this adjustment device, the line is held in such a way that the associated batten is completely stiffened, while in another position the one is more or less relaxed. This fact allows the battens and thus the sail itself to move more or less. niger to bulge under the action of the wind. However, the curvature depends exclusively on the wind pressure and cannot be changed by the skipper while sailing.

The invention is based on the object of a device for adjusting the curvature of a boat sail 7U, which allows the operator while of the sail and independently of the wind pressure to influence the curvature of the sail io that the sail a form adapted and suitable to the prevailing conditions is given.

This object is achieved according to the invention on the basis of a device of the type mentioned at the beginning solved that on each side of his sail at least one with its one end on a fastening device Line attached to the batten at the attachment point and one at a distance from the attachment point Umlcikeinrichtung attached to the batten at the point of deflection provided for the line are, and that one line each via its deflection device down to the one assigned to it and holding it Facility is led.

In a preferred embodiment of the device according to the invention are between the fastening device and guide devices for the deflection device at an intermediate point on the batten intended for the leash.

With the aid of the device according to the invention, each batten can be used in one or in opposite directions Senses are curved by looking at the matching of the associated. Linen pulls. on

FIGS. 26 and 27 are schematic representations of two further embodiments and

Figures 28 to 32 are perspective views of some fittings

In the first embodiment according to FIGS. 1 and 2, a mainsail V is provided with a batten L. At one end of the lath L, at the point A , a line / is attached, which is guided at the other end of the lath at a point B and is deflected downwards. The curvature of the bar is determined by the pull. which is exercised by means of the leash / between points A and B. The dashed lines between A and B show the unloaded crossbar and the tension-free line /. The lines between A and B, however, show due to the train! A / curved latte L. The shortening of the line 1 due to the tension between the points A and B is equal to the distance AA ',.

In FIGS. 3 to 10, various exemplary embodiments for the arrangement of the line / in relation to the slat L are shown schematically in sectional images which in principle correspond to FIG. In Fig. 3 a guide device e is provided between the fastening point A and the deflection point B for guiding the line / at an intermediate point C. In order to achieve a certain curvature of the lath, a smaller shortening of the line / is necessary. In Fig. 4 a guide device e is also provided between the points A and B , but this is located at the free end of a Seising d, which is attached to the intermediate point D on the lath L- . A shortening of the line is necessary to achieve a certain curvature of the batten, which

before lies between the shortenings required in the case of FIGS. 2 and 3. In FIG. 5, two guide devices e are provided for guiding the line, the associated Seisinge d _x and d _{2 being} attached to the lath L at the points D _x and D ₂ . In Fig. 6, a Seising d _{3 is} attached to the slat L at the point D ₃ between the points A and B , the free end of which is attached to the line / at the point F without slack. In this case, the arch D ₁ B can continue to be curved more strongly, while the arch AD ₃ is no longer curved more strongly by further pulling on the line /. In FIG. 7, a sheath / is sewn into the sail at the level of the batten L , in which the line / is slidably mounted. The arches AD ₄ and D _S B on both sides of the case / can be changed noticeably, while the part of the lath adjacent to the case / is only slightly curved. In FIG. 8, the lath L is curved by two lines / and / 'which are fastened at points A and A' and guided through two deflecting devices b and b 'designed as eyelets, which are located at point B on lath L are attached. The line / is also guided at an intermediate point C on the crossbar. Between the points A and C the line / is provided with a rope clamp O , which limits the curvature of the arc AC by pushing against the intermediate point C , while the arc CB can be bent even more by further pulling on the same line. The other line / 'is added so that the curvature of the bow A ¹ B can be increased and the bow CA' can be straightened. In FIG. 9, only one line / two intermediate points C _x and C _{2 are provided} on the lath L for guiding. Two rope clamps O _x and Oj are attached to the line / between points A and C ₁ and points C ₁ and C ₂ , which limit the curvature of the arches AC _t and C ₁ C ₁ , while it is possible to go through Another pull on the leash / to bend the bow C ₂ B even more. In Fig. 10 the lath L is curved at its ends by independent lines /, and / '.

The figure! 1 shows the use of a second exemplary embodiment in a headsail W. On the sail, battens L _x , L ₂ and L ₃ are arranged parallel to the foot. Their ends adjacent to the luff G are provided at points B ₁ , B ₂ , B _} with deflection devices b _x, b ₇ and b _{3 designed} as eyelets. At the opposite ends of the slats, at points A ₁ . A ₂ and A ₃ , lines / or / _{2 or / 3 are} attached, which are connected to a maneuvering line / below the luge-ordered deflection eyes b _v b ₂ , b ₃ , which runs parallel to the luff G at a small distance . The furling line is g ρ placed around a pulley that is located near the Vorsegelhalses formed by the upstream and leech, and astern performed and on a fixedly connected with the cover cleat / busy Shortening the furling line g effected by a certain length that the lines / „/ ₂ and / ₃ bend the corresponding battens. If the battens are of the same length and properties, the curvatures are the same for all battens. The likewise curved track of the battens projected onto the plane of the drawing in FIG. 11 (provided that the non-curved parts of the sail remain parallel to themselves) are shown in dashed lines as V ₁ , V ₁ and V ₃ , as is the track r 'of the figure eight -Ueks r and the leech. From FIGS. 12 and 13 it can be seen how the sail W is arched when the maneuvering line £ is shortened

The third embodiment shown in Fig. 14 shows a different arrangement of battens and lines in the same headsail. The battens are arranged perpendicular to the luff G. Each of the pulling lines is in turn attached to a single maneuvering line g .

The track of each curved batten in the plane of the drawing in FIG. 14 coincides with the track of the uncurved batten except for the attachment points A ₁ , A ₂ and A ₃ , where the lines / "/ ₂ and / _{3 are} attached and those on the Places A \, A ' ₂ and A' _{3 are} projected. With this one

ίο The embodiment can be arched without the sail that the slats are subject to torsion. The sail can also be provided with battens of different lengths, which extend over the entire sailing depth available at the respective point, namely

π on the one hand between the luff G and on the other hand between the leech r or the foot.

In the fourth embodiment shown in FIGS. 15 and 18, the application to a mainsail V which is set on a mast M and a large boom N is shown. The sail V is slatted L _t ..., L ₄ provided that at the fastening points / 4, .... A _4, which are arranged near the leech r, fastening means o, ..., bear a ₄ . Each line / 1 ..., I ₄ is deflected in a deflection device b _x ..., b ₄ and then guided down to the deck of the boat. In this case, each line is held in the vicinity of the surface of the sail by further guide devices e, which are preferably fastened to the battens. This ensures that the lines between

JO see the guide device b and the deck of the boat run essentially parallel.

16 shows a fifth embodiment, corresponding to the second and third embodiment, for a mainsail V with battens L _x ..., L ₄ .

The pulling lines /, ..., I ₄ are linked to a maneuvering line h , in each case below the associated deflection device b _x ... b ₄ , so that only the line h needs to be operated from the deck. A certain shortening of this line produces an equally large shortening of the tension lines between the fastening devices α, .... a ₄ and the deflection devices b _x .... b _{4 of} the slats. The dashed line r ' shows, as in FIG. 15, the position of the leech r with a certain curvature of the battens.

The sixth exemplary embodiment shown in FIGS. 17, 19 and 20 is also intended for use with a mainsail V with battens L _x ..., L ₄ . The battens extend from the leech r to the luff H on the mast M and are divided by two rows

so curved by lines /, ..., / ₄ and / ', ..., V ₄ The lines /, ..., I ₄ are attached to fastening devices α, .... a ₄ near the leech r and guided via deflection devices b _x ..., b _A In addition, they are tied to a maneuvering line h that touches the deck of the boat. The lines / Ί ..., 1 ' ₄ are correspondingly attached to fastening devices a' _x ... , a \ and guided over deflection devices b \ .... b ₄ and also attached to a maneuvering line h 'leading to the deck of the boat . When the lines h and h 'are pulled to a certain extent, each batten bends in a manner as shown in FIG. 10. The dashed line r' is obtained as the track of the leech r. The aft part of the sail between the batten L _x and the clew / formed by the leech and foot would be subject to tension if this were not avoided by sliding the clew along the boom N in the direction of the mast to the point / ' can.

In the seventh embodiment shown in FIG.

For example, a device is provided by means of which the clew / according to the curvature of the sail V is longitudinally displaceable. This device is necessary if the next to the large tree W under «-,; -; The crossbar L _x is within a certain minimum distance from the large tree N. This avoids the aforementioned distortion of the mainsail. A line / _{0 is} attached to the clew I , which is laid around a line P ' attached to the boom N near the mast M The maneuver line h , which is used to bend the battens L _x ... serves. The two lines / ₀ and h are connected to one another behind the deflection point at the route p ' , so that a given shortening of the pull of the maneuvering line h has the same effect on the learning / _0. The clew / and the attachment point A _{x of} the line / on the first batten L _x are therefore shifted by the same amount by a single pull on the maneuvering line h. The sail V puckers at his damaged on the main boom N UnterUek.

The lower part of the sail V should have enough width to allow the batten L _{x to bend.} The clew / is pulled aft by a line s which is wrapped around a pulley q attached to the extreme end of the grotto tree N. This line s is attached with its other end to one end of an elastic gliHes u , for example a metal spring or a rubber sling, the other end of which is attached to a large tree .V The link u is already stretched when the clew / assumes its normal position. When the clew is pulled forward to the steering by the line / ₀ , the link u is stretched by the line s by this displacement distance. When the clew / is on the steering / 'the line s and the link u take the position s ' and''as shown in Fig. 21 shown in dashed lines.

In the eighth embodiment shown in FIGS. 22 to 25 it is shown in detail how the clew / mainsail Vm formed by the stern and lower uek can be shifted as a function of the curvature of a batten L ₀ when this is close to the lower uek of the large tree is located. The batten L ₀ is housed in a SeseUattentasche which is provided on the sail V in a known manner. In contrast to the previously described embodiments of mainsails, the sail is not in direct connection with the boom N. Two connecting links I ₀ and i'o siod are screwed to the unit formed by the sail and the batten L _0. The connecting link / '"is attached to the end of the crossbar L ₀ adjacent to the mast M and to the large boom W about a fixed axis Z ₁ Z' that is genuinely related to this, and pivots". The within a certain distance from the A-hterliek the crossbar L _n is attached to link / ₀ a of the main boom N vertical axis Z, Z 'pivotally mounted with respect to the Großbaumnockbeschlag U You-Großbaumnockbeschlag U is arranged longitudinally displaceable on the main boom W and designed as an upside-down U. During its sliding movement, it is held by two rails ν , which are attached to both sides of the large tree and terminate with stops w. The large boom fitting L is provided with a clamping device / ₀ , which is used to hold a maneuvering line h . The main boom fitting U is pulled backwards by means of a retraction line s, which is placed around a tube q and connected to a resilient member u that is attached to the main boom N by means of a pull line H ₀ connected to the maneuvering line ti arranged in the vicinity of the mast M. the large tree nock U can be pulled forward. A roller p 'is arranged on the large tree N , by means of which the glue ti. and n _{0 are} deflected so that a horizontal train is possible. Next to the roUe p ' there is a clamping device / V for the maneuvering line ti. In addition, a cleat / is attached to the main boom N , which is used to secure a hauler S ₁ , which is connected to the retraction lines s arranged on both sides of the main boom . The lath L ₀ is curved by means of two lines / ₀ and l ' _o. The line I ₀ is attached to the fastening device a _0, which is designed as an eyelet, of a fitting near the leech and is designed as an eyelet.

n deten deflection device b ₀ out, which is provided on a fitting / ₀ , and is attached to the line h . The line V _{0 is} correspondingly guided to a fastening eyelet of the fitting / ₀ attached in a looping loop b'o of a fitting / and is attached to the line ti . The lath L _x above it, like the laths that follow it in height, is equipped accordingly. The fitting / fastened to the crossbar L _x perpendicularly via the coarse boom fitting U carries a deflecting eyelet b _x , a fastening eyelet a '■ and a guide device e designed as an eyelet for the

Leash h. The fitting for the end of the lath L _{1, which} is close to the mast M , has a deflection eye />', and a guide eye e \ for the line ti. A curvature of the rear part of the sail, which hovers freely above the boom N from the boom fitting U , is obtained when the line h is pulled down by the desired amount and the line h is then held in the clamping device t ₀ . However, this maneuver has no noticeable effect on the front part of the sail. Up to now there has been no change in the position of the large boom fitting U. The curvature of the front part of the sail is obtained by pulling the line ti downwards. Thanks to the RoUe p. which deflects the line ti , it only needs to be pulled back. The maneuvering line ti then operates the lines V ₀ , / ',. ·· and bends the associated part of the battens. The line ti also pulls the pull line n "with it, which exerts a pull on the boom fitting U and pushes it forward by the same amount by which the line ti was shortened. In addition, the elastic member u is stretched over the line s by the same distance. The range of action of the limb u is determined by fastening the ϊο line S ₁ to the cleat t after the maneuver with the line ti. To give the front TeO of the sail a weaker curvature, the line ti is released from the clamping device / '" and gives in the desired length on the leash. The retraction of the line ti upwards is ensured by the elasticity of the battens and the action of the elastic member u . In this embodiment, the curvature of a front and rear area of the sail can be adjusted independently of one another. From FIGS. 23 and 24 it can be seen which changes take place when the device is actuated. After a train to the not shown in these figures, linen h and ti the fittings I ₀ and i _"0 pivoted are to conform to the curvature of the bar in position. The Großbaumnockbeschlag U is along the rails ν by the train of the lines / I ₀ , which have been dragged along by the learner ti , moved forward. From Fig. 25 it can be seen that in this embodiment for a mainsail V the battens Z ₀ ..., L _{4 have} different lengths and as

eyelets formed deflection devices b ₀ ..., b ₃ for the lines / ₉ ..., I ₃ are at the same distance from the stern hek. The maneuver line h is practically parallel to the leech. The fastening devices α Ό .... a _{4 designed} as eyelets are arranged at the same distance from the line h in the vicinity thereof. The maneuvering line h ' runs parallel to the mast M. The rear part of the sail is through the lines Z ₀ ..-. I ₃ arched of the same length, while the front part by the lines / ' ₀ ..., Ϊ, arched of different lengths

In FIGS. 26 and 27, two further exemplary embodiments of the device for mainsails are shown schematically. In the embodiment according to FIG. 26, the line h actuates the pull on the lines I ₀ ..., I ₃ , which are arranged in the lünteren part of the sail, and the lines T ₀ - ··. 'V which are arranged in the middle area of the sail V , attached to the fastening _{devices α "0} ..., α" and guided on deflection devices b * ₀ ..., b " _{3 designed} as eyelets.

A'j on the battens and to the deflection devices b ' _o .... b' designed as eyelets _3. In the embodiment according to Fig. 27, the lines h and A 'cause the rear and front part of the sail to curve in a corresponding manner, while the middle part of the same is not carried out by the line h, but by a further line k'. " Can be arched - pulling lines V""..., l '" _{3 are} tied to this line h ", which are attached to fastening devices a'" ₀ ..., a '" ₃ in the vicinity of line A and through as eyelets trained guide devices e '" ₀ · · ·> ^e " i are guided.

The fastening devices for the lines / ' ₀ ... are arranged between the guide devices e'" ₀ ... and the mast. Which curvature is r" with the help of the lines A 'and h'" in the front or middle area of the sail can be achieved is shown in FIG.

28 shows a fitting with a fastening device Ci _{0 designed} as an eyelet, as it is, for. B. can be provided at the fastening point A _{0 shown in} FIG. 22 and is to be fastened on a lath. Egg has a layer L '" of pliable material on its side that comes into contact with the sail.

The fitting shown in FIG. 29 is used to attach one end of a line. The one as an eyelet trained fastening device α * for the leash is by a flat bar ll at a certain distance held to the screw-on part of the fitting. This fitting facilitates the curvature of the slat, though a slight curvature is to be achieved.

In FIG. 30 it is shown how a fitting with a fastening device a _{k designed} as an eyelet, a fitting with a guide device e _{k, designed} as an eyelet, and a fitting with a deflecting device b configured as an eyelet are fastened in this order to a slat and by a Tow line / are connected to each other. When pulling on the leash / the bar bends from the position shown in dashed lines to the position shown excellently. The fitting according to FIG. 31 has a rectangular opening 12 in which a flat bar 13 provided at its ends with guide devices e _{k designed} as eyelets is slidably mounted. The guide eyes e _k serve as a guide for the lines l _b and / ,. The freedom of movement of the flat bar 13 in the opening 12 is limited by the eyelets e _k that do not fit through the opening 12 and can strike the screw-on pieces of the associated fittings. An application of the fittings with the guide devices is shown in FIG. 32. In this, a slat L is bent under the action of the line /, which is shown drawn up. The line / is a _k secured to the mounting device by means of two guiding e _k devices out on two flat bars 13 and jo at the deflection b _k deflected. The line l _{b which} is not under tension is held at a small distance from the convex surface of the sail by those guide devices e _{k which are} in contact with the fittings belonging to the trains on this side. With dashed lines in this figure the reverse curved lath standing under the pull of the line / ,, is drawn, the line /, not being drawn and through the guide devices e _k located on the now convex side in the vicinity of the sail is held. When changing the curvature of the batten, the flat rods 13 slipped through the openings 12 by the entire length available. In this arrangement guides for lines are used, which protrude noticeably from the sail only on the concave side of the sail. This advantage is not achieved when using a fixed flat bar 11 according to FIG. 30. A flat shape of the bar is desirable because it limits the risk of twisting in the opening or entanglement
