Description

Rigging arrangement

Field of technology

The invention relates to a rigging arrangement comprising a propellant sail, including semi-rigid and rigid sails, in particular for propelling sailing ships, and further comprising control elements for adjusting and controlling the sail and reinforcing elements for the sail.

Prior art

Previously known rigging includes different types of sails combined with different types of controls and reinforcements. The sails are usually attached to the mast, the control elements being in particular ropes enabling the capture of the wind force response from the sail to the vessel. With regard to easier control of the tarpaulin setting and the possibility of reducing the control force, the ropes are guided by suitably placed dies and possibly over pulleys. The aim when propelling the boat is to achieve the smallest possible restriction of driving in the desired direction, regardless of the wind direction. At the same time, it is also an effort to achieve the highest possible coefficient of wind driving force. Various designs of rigging have to some extent succeeded in meeting these efforts, but at the cost of demanding control of the rigging and its complexity.

The essence of the invention

The object of the present invention is to increase the coefficient of driving force of the rigging while achieving simpler operation, both manual and mechanical.

The essence of the rigging arrangement according to the invention lies in the fact that the tarpaulin is connected in its lower part to a transverse boom forming independently or in connection with the tarpaulin a flexible control frame, the tarpaulin being rotatably and pivotally mounted with its upper end around the mast. Part of the tarpaulin are possibly elastic stitches.

The tarpaulin is optionally two-layer, connected at its circumference, the mast passing between the layers of the tarpaulin. Alternatively, the tarpaulin is double, the first part of the tarpaulin being arranged on the opposite side of the mast than the second part. The transverse boom is provided with a control rope or a sliding guide, the control rope being slidably connected to the mast by means of a belt or a die, or the sliding guide surrounds the mast.

The advantages of this rigging arrangement are to achieve greater stability of the vessel, the need for less actuating force to control the sail and a better ability to control the center of gravity of the sail relative to the keel of the vessel, to a greater extent. At the same time, this arrangement combines the advantages of surf control with the efficiency of junk sails and provides the possibility of a controlled position of the lateral comparable to the surf with a fixed mast position.

Examples of embodiments of the invention

Fig. 1 shows the arrangement of a rigging (bow type) on a vessel 1, where a tarpaulin 3 is rotatably and pivotably mounted at its upper end to the mast 2, which is reinforced on its sides by elastic stitches 5. The lower end of the tarpaulin 3 is free, the lower ends of the elastic stitches 5, which are part of the tarpaulin 3, are connected to the transverse boom 4, also elastic or rigid, which extends on the opposite side from the mast 2 to the tarpaulin 3. 4 or an actuating rope 6 is attached to the flexible stitches 5, which is slidably connected to the mast 2 so as to form a loop on the mast 2, or can pass through a die arranged on the mast 2. The vessel is further provided with a rudder 11. The actuating rope 6 can be replaced by a sliding by a guide which surrounds the mast 2 on both sides and is connected to the transverse boom 4 or to the elastic stitch 5. The upper bearing of the tarpaulin 3 on the mast 2 and the encirclement of the mast 2 by the control rope 6 does not aerate against undesired vertical movement of the tarpaulin 2 If the tarpaulin 3 is not reinforced with elastic stitches 5, it is suitable to form the tarpaulin 3 from a material of defined stiffness against undesired shaping of the tarpaulin 3 in the event of an onslaught of air.

The lower part of the tarpaulin 3 in connection with the transverse boom 4 forms a flexible control frame by means of which the tarpaulin 3 can be rotated around the mast 2 and pivoted on the mast 2.

Fig. 2 shows an arrangement of a rigging (wing type), where the tarpaulin 3 is double-layered, each layer of the tarpaulin 3 extending on the opposite side from the mast 2. In this case it is possible to dispense with the use of the control rope 6, the transverse boom 4 being form as a closed circle or oval, possibly with another closed shape, which is connected to the tarpaulin 3 and extends around the mast 2. Also here the lower part of the tarpaulin 3 in connection with the transverse boom 4 forms a flexible control frame by which the tarpaulin 3 can be rotated around the mast. 2 and swing on the mast 2.

Fig. 3 shows an arrangement of a rigging (gate type), where the tarpaulin 3 is double, formed of two parts provided with elastic stitches 5, by means of which the tarpaulin 3 is rotatably and pivotably mounted on the mast 2 at its upper end. guided on the opposite side of the mast 2 to the second part of the tarpaulin 3. The elastic stitches 5 are connected in the lower part to a transverse boom 4, which is formed as a closed circle or oval forming an actuating frame. In this embodiment, the control rope 6 is always slidably connected to the mast 2, either by encircling the mast 2 with a loop from the control rope 6 or by passing the control rope 6 through a die fixed to the mast 2 (not shown).

In all the above-mentioned embodiments, it is possible to use both a conventional and a semi-rigid tarpaulin 3 or a rigid tarpaulin 3.

Figures 4, 5 and 6 show the individual positions of the sail 3 and the transverse boom 4 with respect to the mast 2 and the direction of navigation of the ship in the wind direction 12 shown by a strongly marked downward arrow. Fig. 4 shows a vessel 1 with a bow arrangement, Fig. 5 shows a wing arrangement and Fig. 6 shows a gate arrangement.

Giant. 7 shows a rigging arrangement according to the invention on a snowmobile with a seat 7 and rails 8. The arrangement of the tarpaulin 3 is similar to that of FIG. 3 (gate arrangement), the tarpaulin 3 being rotatably and pivotally attached to the vehicle's mast 2 at the upper end. The transverse boom 4 forms a closed circle or oval for easier control by the driver, the tarpaulin 3 being provided at the lower end with sidewalls 13 which are connected to the transverse boom 4. The transverse boom 4 and the lower part of the tarpaulin 3 with the sidewalls 13 form an operating frame. A similar arrangement as in Fig. 7 can be seen in the vehicle of Fig. 8, where the rails 8 are replaced by the wheels 14 of the vehicle.

Giant. 9 and 10 show one of the possibilities of guiding the control rope 6 on the mast 2, where one control rope 6 forming a loop around the mast 2 is guided in a spool 15 and each end is connected to a transverse boom 4, in this case two opposite transverse booms. 4.

Figures 11 and 12 show another possible embodiment of the control rope guide 6, in which two control ropes 6 are used. Each of the control ropes 6 forms a loop on the mast 2 in the spool 15 and the ends of one control rope 6 are fixed on the left 4 and the ends of the second control rope 6 on the right part of the transverse boom 4.

Fig. 13 shows three positions of the tarpaulin 3 when operated by the control frame, the tarpaulin 3 in the vertical position is shown by a solid line and its swing to the right and left in each case in dashed lines, each position of the tarpaulin 3 being marked by an imaginary center 16 representing the center of gravity of wind force. in individual positions of the sail 3.

Giant. 14 shows the application of the propellant rigging according to the invention to a large merchant ship, where the sail arrangement according to the invention can be used as an auxiliary propulsion of the ship. The control rope 6 is replaced by a sliding guide which surrounds the mast 2 on both sides and is connected to the transverse boom 4 or to the elastic stitch 5.
