ί | Rig and sails for a windsurf board.

The innovation concerns a rig and sails for a windsurfing board with one by means of a mast and one of two at the ends Large trees connected to one another, a spreader gaff or a boom, the sails held upright and open The luff is connected to the mast, which is unlinked with respect to the windsurfing board and freely rotatable on all sides by means of a joint pivotally attached to the windsurfing board rig held by the user in each case on one of the large trees and thus relative to the jf wind and windsurf board is adjusted, whereby the clew of the sail with the boom via a in document clamps on the large trees fixable trim sheet is connected to the nock, the failure of the sail from the nock runs obliquely down to the mast and the boom is arranged above the sail neck, and wherein the boom is further connected to the foot region of the mast : · Connecting Niederh'oler is provided.

Such rigs are generally known and correspond to the Spreizgaff.eltakelung, which has been used in both non-stiffened and stiffened rigs in many embodiments (see Herrishoff Manufacturing Company, advertising brochure, New York Public Library 19 ¹ IO, DE-AS 19 14 604) . The advantages of the real spreading gaff rigging are undisputed in the professional world (Grohmann, Hans, "Das Segel", Verlag F. Bruckmann AG, Munich 1937, pp. 37-42).

With all sailing vessels, however, there is always the problem that by climbing the boom the optimal trim of the sail and especially the control of the leech of the sail is problematic.

table is. This problem is attempted in conventional sailing vessels in which the sail is operated by means of a mainsheet to be remedied by guiding the mainsheet slide accordingly on a traveler rail. In particular, will be too generally vang used, which pull the boom down in the direction of the mast base.

This problem is particularly severe with rigs for windsurfing boards, since here the rise of the Baymes is not counteracted by a mainsheet will. All forces must therefore be absorbed by the leech and the foot of the sail. At regattas That is why people tried to puncture even with windsurfing boards the boom taking over the boom to be pretensioned by a vang in the direction of the mast base. Furthermore it is too known in windsurfing boards to connect the clew of the sail with the nock of the boom via a trim sheet, by means of which the distance between the wing and clew and thus the tension in the leech and foot according to the present Wind conditions is adjustable. Due to the flexibility of the entire system in rigs of the type referred to above however, these attempts did not lead to optimal results.

Therefore, the innovation is based on the object at a rig of the above ArL complete control of Ae.fc ^ he liek and to allow the foot.

According to the innovation, your task is essentially achieved by that the vang is connected to the clew of the sail via the nock <ies Gabe] baunies by means of a continuous sheet, which is at least displaceable with respect to the nock and at the same time forms the trim sheet of the rig.

Through the new reunp; is achieved that automatically through the connection swi.ii: lit-n N: i edcr'hoJ er and Si: fm V. horn a tendency of the GabeJbaumos,.: U r.lcixen, thereby becoming rjntgt-jgengew Lrkb that,

apart from the already existing vang effect, at the same time the tension in the leech and foot is increased. The sail of the newer rigging is therefore always in the selected trim.

In a preferred embodiment according to the innovation, a block with a roller for guiding and deflecting the trim is on the cam Schot provided.

In particularly preferred embodiments according to the innovation, one or more bottle pulls or tackles are provided between the vang and clew, which are also traversed by the continuous trim sheet. This has the particular advantage that the desired distribution of tension between leech and foot can be determined by appropriate selection of the transmission ratios. For example, with a sail with a relatively loosely cut leech, the user will transfer 60 % of the tension applied via the vang to the leech and only 40 % to the leech.

Further advantageous details and developments according to the innovation are characterized or given in the subclaims from the following description in which the innovation is illustrated by way of example in the drawings Embodiment is explained in more detail. It shows:

In the embodiment illustrated in the drawings, a symmetrical design was chosen so that the trim sheet can be operated from both sides. It is expressly pointed out that, of course, an asymmetrical | See arrangement can be chosen without deviating from the basic idea of the innovation. In such embodiments * only individual blocks | instead of the blocks provided in pairs ke are used, which are then assigned to a page.

FIG. 1 generally shows a rig 1 according to the innovation, which is connected to a windsurf board 3 via a universal joint 2. The rig 1 with the associated sail 4 consists of a mast 5 and a boom 6. The boom 6 consists of two outwardly curved large trees 7 and 8, which are connected to one another at their front end 9 and the nock IO. The front end 9 of the boom 6 is attached to the mast b in a known manner. The luff 13 of the sail 4 is attached to the mast 5. The clew 12 of the sail is connected to the nock 10 via a trim sheet 13. Furthermore, the cam is pretensioned in the direction of the mast foot 15 via a vang I ^. In Fig. 1, 16 is the leech and 17 is the leech of the sail 4.

The special features according to the innovation are explained in more detail below with reference to FIGS. As As can be seen from FIGS. 2 and 3, the vang 14 is connected to the clew 12 of the sail A via a deflection at the nock 10 of the boom 6 connected by a continuous sheet, which is formed by the trim sheet 11. "

In the illustrated in the drawings, preferred embodiment this connection takes place via a number of

I · Il

Blocks that have a favorable power transmission in the manner of a Piaschenzuges In addition, as shown, the arrangement is symmetrical to adjust the trim of the sail to be able to change both sides while surfing.

For this purpose, the trim sheet 11 is at one end in a document clamp 18 on the boom 7 and at the other end in a Document terminal 29 on large tree 8 occupied.

Starting from the document clamp 18, the path of the trim sheet 11 is described below.

From the first document clamp 18, the trim sheet is first guided backwards to the cam 10 around a roller mounted in a fitting 19 which connects the two large trees 7 and 8 to one another and which is provided in a first deflection block 20. From there the trim sheet 11 runs to a first trim block 21, which is connected to the clew 12. From the trim block 21, the trim sheet runs obliquely downwards to a first prevention block 2 ′, which in turn is connected to the cam 10 or the fitting 19. Diverted around the connecting block, the trim sheet 11 runs in the direction of the mast foot 15 to a first vang deflection block 23, which is connected to the vang 14. In the case of an asymmetrical arrangement, the trim sheet 11 can also be connected directly to the vang 14 at this point. In the preferred embodiment, however, the outhaul 11 runs back in the direction of Mock 10 to a connected to the fitting 19 vang 24 and by this redirected again to the front in the direction of the mast foot 15 to a second Niederholerumlenkblock ^J 5. extends deflected uiesen the Trirnmschot turn in the direction of the cam 10 around a second connecting block 26 which is connected to the fitting 19, then around a second trim block 27 which is connected to the clew 1? connected is. Diverted around the trim block 27, the trim sheet 11 runs back to the nock 10 to a second deflection block 2ti,

which is mounted on the fitting 19 and finally forward to the document clamp 29

It is pointed out at this point that the representations according to Pig. 2 and 3 are to be understood as schematic and the various blocks as individual blocks for a clearer representation were shown. It is obvious to a person skilled in the art that double and triple blocks can be used instead of the blocks shown individually are.

In order to ensure the greatest possible play in the necessary To give directions that result from the movements of the rig and of the sail, these are illustrated in the figure Way mounted movably in all directions.

The blocks 22 and 26 can be pivoted on a horizontal axis 30 which in turn is fastened in an articulated bracket 31 which is connected to the fitting 19 is.

The vang deflection block 24 is movable on a bracket 32 stored, which is connected to the axis 33 of the blocks 22 and 26. The connection between the clew 12 and the Blocks 21 and 27 are preferably also carried out via a bracket 34 with an axis 35. Those illustrated in the drawings Brackets 31, 32 and 34 can also be conventional legs.

The blocks 23 and 25, which are preferably combined into a double block, are via a swivel fitting 36 with the Vang 14 connected. The same applies to the storage of the blocks and 28 at the rear end of the fitting 19 in such a way that these blocks can also be pivoted.

In Pig. 4 is a schematic, exploded view again the way of the trim sheet 11 to the roles of

different blocks are shown, the attachment points, i.e. H the nock 10, the clew 12 and the vang 14 are illustrated as dashed fields.

It is evident from the description of the exemplary embodiment that as soon as the boom 6 shows the tendency to rise, the tensile stress thereby generated in the vang 14 immediately above the pulley systems formed by the various blocks are transmitted to the clew 12 and consequently the tension the leech and foot is increased. In what ratio this tension from the vang 14 on leech or Is distributed lower leech, can be determined that, if necessary, a translation by further blocks between the Vang and the nock 10 or between the nock 10 and the clew 12 is interposed.

At the same time, the rig described can be trimmed from both sides of the sail 4 via the trim sheet 11 without any changes.

According to a further, particularly preferred feature of the innovation, the entire system can also be designed as a kit, by means of whose existing booms can be converted. A design / example of a molded part required for this, which can be connected to the fitting 19 of an existing fork tree is shown in FIG. 5 in a schematic sectional view shown, with the associated connection block for the clew 12 or the connection with the vang 14 serving Fitting has been omitted, since this can correspond to the embodiment according to FIG.

As shown in Fig. 5 in a side sectional view, the Molded part 40, which is preferably made of plastic, but can also be made of metal, designed such that he positively ijber the fitting 19 of an existing fork

tree 6 can be applied. For this purpose, the molded part 40 is divided into two hinged halves 41, 42, which are connected at the rear end 43, which forms the cam IO, either by a hinge (not shown) or preferably by the fact that, in the case of plastic as the material, there are none Separation takes place. In addition to the half-shells 44, 45 which overlap the part of the boom 6 or fitting 19 which is round in cross section, the molded part 40 also has two opposing mating surfaces 46, 47 _; which take up the material strip 48 which is present at this point in commercially available fork trees and which normally contains bores 49 (cf. FIG. 3) for the passage of the trim sheet. In order to achieve a better fit of the molded part 40, a pin 50 can also be provided at this point, which engages in these openings 49!

The two hinged halves 41, 42 of the molded part 40 are preferred over the fitting 19, enclosing it held together in that the storage of the bracket 31 at the same time connect the halves 41, 42 to one another. Of course additional fasteners may also be provided, although this is not required as the main forces in Occur in the direction of arrow 51 in FIG. 5 and therefore lie in the plane of the half-shells 44, 45.

A preferred embodiment according to the invention has been described above, and it will be apparent that various Changes and modifications are obvious to those skilled in the art are, without deviating from the original idea of the innovation, which This is seen in the transfer of the forces generated on the vang by deflecting to the clew.
