Seigel device for a windsurfing device.

The invention relates to a sailing device for a windsurfing device, with a boat body, an articulated one attached to it Support mast, a boom connected to the support mast and a sail.

In the currently known windsurfing devices, the sail is on a mast, which is movable on the hull via a universal joint is attached, and firmly connected to the so-called boom by means of a trim sheet. The boom is here designed as a rotating rod, which is attached to the mast, holds the sail and at the same time controls the device relieved. In some cases, the trim sheet is attached to the boom via a sliding device at the end of the boom Clamp led; the trim sheet can do it too loosened and trimmed the sail while driving.

Furthermore, a reefable sail for windsurfing equipment is known, which is designed so that the sail has recesses through which the mast ropes correspond to the windings the sail can be guided around the mast.

By connecting the sail to the mast and boom, which can be rolled up, reefed or tensioned at the same time

of the sail, there are the following disadvantages:

Difficult transport of the necessarily tensioned sail to the water as a result of the effects of the wind. '

Difficult lifting of the sail lying in the water by means of the pull-up line at the start or after a fall, especially in stronger winds and waves, due to the weight of the water acting on the sail and the Actions of the wind.

No adaptation to the different wind conditions; it is necessary to acquire special sails for this purpose for light, medium and strong winds (light weather sails, normal sails, storm sails), which already exist before the start must be attached and cannot be replaced while driving in changing wind conditions.

In contrast, the object of the present invention is to create a sailing device of the type mentioned at the beginning, which, with a simple structure, enables the sail to be rolled up, reefed and tensioned at any time.

According to the invention, this object is achieved in that at A roll-up element which can be rotated and locked about its longitudinal axis is mounted on the support mast via bearings, on which the sail is attached for rolling, reefing or tensioning at any time. This has the advantage that on simple way by the sailing device according to the invention the sail can be rolled up, reefed or tensioned at any time. This makes it easier to transport the sail to the water, the start, as the sail can be stretched on the device, the pulling up of the sail from the water, there the sail lying in the water can be rolled up and reefed at will, the adjustment of the sail to different wind conditions, because the sail can be reefed or enlarged again while sailing on the water.

In a further embodiment of the invention, the roll-up element can be designed as a roll-up mast.

According to a further feature of the invention, the sail can be connected to a tension sheet at its rear end, which is guided to the support mast via at least one sliding element arranged at the rear end of the boom. Here the tension sheet can be arranged approximately parallel to the failure of the sail from the rear end of the boom to one on the support mast Be guided sliding element so that a movement of the clamping sheet can be carried out in a simple manner. This tension sheet can be fixed in a further embodiment of the invention on the mast or on the boat hull, wherein to set the Tension sheet a clamp (b & w * - \ application can. The sail is tensioned and trimmed via the tension sheet, which is secured by a fastening at the rear end of the Sail over a sliding device attached to the rear end of the boom approximately parallel to the lower part, i.e. the Lower edge of the sail, is led to another sliding device attached to the mast. Attach and anytime The tension sheet can be loosened by means of a clamp or cleat also attached to the support mast or the boat body (double-armed latch on which the cordage can be attached).

In a further embodiment of the invention, the boom can be connected to the top of the support mast to the rear Boom end guided retaining sheet are braced against the support mast. The boom is thus advantageous via a retaining sheet in the desired one guided from the top of the support mast to the rear end of the boom Height held.

In another embodiment of the invention, the roll-up mast can be connected to at least one torsion spring, advantageously Torsion springs are each arranged in an upper and in a lower bearing on the roll-up mast.

Another possibility for rolling up, reefing or tensioning the sail is to further develop it to connect the invention at its rear end with a counter-pulling device.

Another possibility is that the roll-up mast is provided with a braking and / or stopping device Motor is connected.

The sail is rolled up or reefed by rolling it up onto the roll-up mast after releasing the tension sheet out of the cleat or clamp. This is possible manually using a crank attached to the lower end of the roll-up mast (with locking device for securing the roll-up mast) or via one attached in connection with the tensioning sheet Counter-pull device; but this can also be done mechanically by a spring mechanism attached to the roll-up mast (tensioning takes place by turning the roll-up mast by pulling the tension sheet) or by engine power, whereby a braking or stopping device can be assigned in each case.

In a further embodiment of the invention, the free end of the tension sheet can be connected to a reel that can be rolled up automatically be. The sliding elements can also be designed as rollers for good guidance of the clamping sheet.
