  The present invention is a sail that is used for headwinds or crosswinds (jib sails) and tailwind-only sails (spin sails), eliminating the cumbersome work associated with sail replacement, and even single-seat sailing (single hand) The present invention relates to a sail that can be easily spin-run, can reduce the sail area even during sailing by using a winding device installed in many yachts, and can be neatly protected when the winding is finished.

  In the sailing of a conventional yacht, it was necessary to exchange the jib sail and the spin sail according to the wind direction.

US Patent Publication No. 3828711

  In the sailing of a conventional yacht, it was necessary to exchange the jib sail and the spin sail according to the wind direction. Spin sails require complicated operations to lift and are difficult to handle. To avoid this, undertrained crew had to sail at low speed using the jib sails even during tailwinds. In particular, with a single hand, it was extremely difficult to change sails, raise a spin sail and sail in a tailwind.

  As in Patent Document 1, although a sail similar to this sale has been devised in the past, it has a shape that assumes that the area is reduced by winding the sail with a winding device during strong winds, etc. In addition, it was not possible to use it on the sea where the weather changes because it has not been solved to protect the sale after winding up completely neatly when berthed.

  Accordingly, an object of the present invention is to solve the above-described problems and to provide a sail that can be used as both a spin sail and a jib sail.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a sail used for sailing a yacht, and is a sail having a shape in which two left and right jib sails lifted to the front of the yacht are combined into one. One outhaul 1, one clew outhaul 2 on the left and one on the right, and one bottom outhaul 3 are connected to a winding device on a vertical line between the top outhole 1 and the bottom outhole 3. This is a rhombus that has a groove 4 for the wind, and overlaps neatly when the winder is equipped with a winder equipped on the yacht. It opens to the left and right during tailwinds, and can also be used as a tailwind-only sail. Can be used in the same way as overlapping jib sails.

  The invention according to claim 2 is a sail used for sailing a yacht, wherein at least one top outhaul disposed at the upper end and at least one bottom outhaul disposed at the lower end. And a groove provided in a winding device installed on the yacht on a line connecting the top outhaul and the bottom outhaul, and a groove extending in the vertical direction, and 2 provided on both sides of the groove If the wind is sailing when sailing, the overhanging part can be deployed and used, and if the wind is sailing or crosswind, the overhanging part is folded into a groove. It can be used as a jib sail, and the top outhaul and bottom outhaul are connected to the winding device, and the groove is attached to the winding device, so that Ri, has become a possible unwinding, characterized in that.

  According to the present invention, in the case of a tailwind when sailing a yacht, it can be unfolded and used as a spin sail, and in the case of a headwind or crosswind when sailing a yacht, it can be folded into a groove and used as a jib sail.

  According to a third aspect of the present invention, in the sail according to the second aspect, the lower side portion of the overhanging portion is a curved line curved upward.

  According to the first and second aspects of the present invention, there is no need to exchange the jib sail and the spin sail in accordance with the wind direction, and no complicated operation is required to raise the spin sail. That is, in the case of a tailwind, when the sail is unfolded and sailed, and the yacht changes its course and becomes a headwind or a crosswind, the sail naturally folds in a groove and becomes the same form as a conventional jib sail. In the event of a tailwind again, the sail will unfold again and take on the same form as the spin sail. In addition, since there is no need to change sails, a single hand can easily spin-run regardless of the level of skill of the crew if it is a tailwind.

  Also, the top outhaul, bottom outhaul, and groove can be attached to the take-up device, and the sail can be securely fixed to the take-up device, so that it is possible to prevent the folded portion of the sail from shifting due to a crosswind or the like. .

  Further, since the sail can be folded up by the groove and wound from the groove side by the winding device, the sail can be protected from ultraviolet rays and sea breeze. For this reason, the yacht can be anchored for a long time with the sail wound.

  According to the invention described in claim 3, since the lower side portion of the overhanging portion has an arc shape that swells upward, the oversight is blocked by the overhanging portion (the lower side portion of the sail) during sailing. Preventing and ensuring good visibility.

  The present invention will be described below based on the illustrated embodiments.

(Embodiment 1)
1 to 13 show Embodiment 1 of the present invention.

  As shown in FIG. 1, the sail 100 is used for sailing the yacht hull 7, and has two conventional jib sails, one on each side. The sail 100 includes at least one top outhaul 1 disposed at the upper end, at least one bottom outhole 3 disposed at the lower end, and the top outhole 1 and the bottom outhole 3. Can be mounted in a groove 61 provided in the winding device 6 installed in the yacht hull 7 on the line connecting the two and the groove 4 extending in the vertical direction, and the two overhang portions 100a provided on both sides of the groove 4 , 100b. The overhang portions 100a and 100b of the sail 100 are formed in a substantially triangular shape symmetrical about the groove 4 as shown in FIG. The lower side portions of the overhang portions 100a and 100b are curved upward (inside) of the sail 100, and are located above (inside) a straight line connecting the clew out hole 2 and the bottom out hole 3 described later. It is like that. In the case of a tailwind when sailing the yacht hull 7, as shown in FIG. 3, the sail 100 can be unfolded and used as a spin sail. In the case of a headwind or crosswind when the yacht hull 7 sails, FIG. As described above, the sail 100 is folded by the groove 4 and can be used as a jib sail. Further, as shown in FIG. 13, in the state where the sail 100 is folded by the groove 4 and wound from the groove 4 side with one overhanging portion 100b facing outward, the outer periphery of the sail 100 has a sail protection cover. It is a cover mounting part that can be mounted. Here, the cover for sail protection is comprised with the fiber which has an ultraviolet-ray prevention effect, and can be mounted | worn in the state closely_contact | adhered to the cover mounting part. Further, the sail 100 has one top outhaul 1 above the groove 4, one bottom outhole 3 below the groove 4, and one clew out at the side ends of the overhang portions 100a and 100b. Hall 2 is provided.

  The top outhole 1 and the bottom outhole 3 are attached to a winding device 6, and the sail 100 can be wound up by the winding device 6 as described later. Further, the clew-out holes 2 are respectively attached to jib seats (sail operation ropes, hereinafter referred to as “ropes”) 5.

  As shown in FIG. 1, the groove 4 is formed on a line connecting the top outhole 1 and the bottom outhole 3 on the outer side surface (front surface in the traveling direction) of the sail 100, as shown in FIGS. The edge processing portion of the convex sail 100 that can be mounted in the groove portion 61 provided in the winding device 6 installed in the yacht hull 7 and extends in the vertical direction. Here, in this embodiment, the groove 4 is fixed to the winding device 6.

  Next, a method of using the sail 100 having such a configuration will be described.

  First, a method for attaching the sail 100 to the winding device will be described. The top outhaul 1, bottom outhole 3, and groove 4 of the sale 100 are attached to the winding device 6, and the rope 5 is attached to the clew outhole 2. In this way, the yacht hull 7 sails with the sail 100 attached to the winding device 6.

  At the time of tailwind, as shown in FIGS. 3 and 5, the sail 100 is spread left and right and sailed in the same form as the spin sail. When the yacht hull 7 changes to the windward, as shown in FIG. 4, when the leeward rope 5 is pulled and the windward rope 5 is loosened, the sail 100 overlaps naturally. Further, when the yacht hull 7 changes its course and becomes a head wind or a cross wind, the sail 100 naturally overlaps with the groove 4 as shown in FIGS. 4 and 6, and has the same form as a conventional jib sail. When the yacht hull 7 changes again and becomes a tailwind, the sail 100 starts to open due to the tailwind, and the sail 100 unfolds as shown in FIGS. At this time, almost no operation of the rope 5 is required, but by slightly pulling the rope 5 on the side of the sail 100, the wind turns around to the opposite side of the sail 100, and the spread of the sail 100 becomes smooth.

  Next, a method for winding the sale 100 will be described.

  When it is desired to reduce the lift of the sail 100 during strong winds or when the sail is anchored, the sail 100 is wound up by the winding device 6 to reduce the area as shown in FIGS. At this time, as shown in FIG. 10, by pulling the rope 12 of the winding device 6, the sail 100 is wound and the area is reduced. The lower end portion of the sail 100 is fixed to the drum 6a of the winding device 6 by a rope 9 fixed to the bottom outhole 3 of the sail 100 as shown in FIG. Moreover, the upper end part of the sail 100 is wound up by the winding part 6b rotating as shown in FIG. As described above, when the rope 12 wound around the drum 6a is pulled, the sail 100 is wound up by rotating the drum 6a and the winding portion 6b. When the sail 100 is completely wound, the cover mounting portion is wound with the outer periphery covered as shown in FIG. In other words, the wound portion of the sail 100 is in a state in which the outer periphery is covered by the sail protection cover. Further, the pulling portion 6c pulls up the sail 100 upward, and tension is applied between the top outhole 1 and the bottom outhole 3 by pulling up the sail 100 strongly.

  As described above, according to the sail 100, there is no need to exchange the jib sail used in the headwind or the crosswind and the spin sail used in the tailwind according to the wind direction, and a complicated operation such as raising the spin sail is performed. Is no longer necessary. That is, in the case of a tailwind, the sail 100 is unfolded and sailed, and the sail 100 is sandwiched on both sides of the groove 4 so that a sufficient speed can be obtained. Further, when the yacht hull 7 changes its course and becomes a head wind or a cross wind, the sail 100 is folded by the groove 4 mounted in the groove portion 61 of the winding device 6 and has the same form as a conventional jib sail. In the case of a tailwind again, the sail 100 naturally expands to the left and right and has the same form as a spin sail. During this time, the crew does not need to perform complicated operations on the sail 100. In addition, since there is no need to change sails, a single hand can easily spin-run regardless of the level of skill of the crew if it is a tailwind. Further, since the sail 100 is folded and doubled to increase the strength, the thickness can be reduced. Further, by reducing the thickness of the sail 100, an effect similar to that of the conventional spin sail occurs.

  Further, the sail 100 is supported on the lower side by three points, ie, two clew out holes 2 and a bottom out hole 3, and the groove 4 is fixed to the groove 61 of the winding device 6, so that the sail 100 is crushed. There is no, you can sail stably. Here, the conventional spin sail has a triangular shape and is unstable because there are two fulcrums on the lower side of the sail. Therefore, it was necessary to stabilize the spin pole from the mast to the sail and widen the sail. However, because the sail 100 is supported at three points, it is highly stable and does not require the use of a spin pole. In other words, work on board can be greatly reduced, so comfort and safety are greatly improved.

  Also, simply attaching the top outhole 1, the bottom outhole 3 and the groove 4 to the winding device 6 causes the sail 100 to overlap on the left and right when winding, and friction is generated on the overlapping surface, so winding is easy. Is possible. For this reason, in the case of headwind, crosswind, or strong tailwind, the sail 100 is quickly wound up by the winder 6 to reduce the area, and the sail can be easily and stably sailed with the same sail regardless of the wind direction and wind speed. it can. That is, since sailing in all directions can be easily performed, the operability of the yacht can be dramatically improved. Further, the top outhaul 1, the bottom outhole 3, and the groove 4 can be attached to the winding device 6, so that the existing winding device 6 is not required to be modified and can be easily introduced.

  Further, since the groove 4 is mounted in the groove 61 of the winding device 6, when the sail 100 is folded by the groove 4, the folded state can be maintained without the crease being shifted. For this reason, since the shape of the sail 100 is stabilized, the yacht hull 7 can sail stably. Further, since the groove 4 is attached to the winding device 6, the sail 100 can be easily wound and unwound by the winding device 6.

  When the sail 100 is rolled up, the sail 100 is folded over with the groove 4, the cover mounting portion 4 is turned outward, the winding is wound from the groove 4 side, and the outer periphery is covered with the cover mounting portion 4 with the protective cover mounted. Can do. That is, in the state in which the sail 100 is wound up, the cover mounting portion 4 to which the protective cover is mounted is on the outside, so that the sail 100 can be protected from ultraviolet rays and sea breeze. For this reason, the yacht hull 7 can be anchored for a long time with the sail 100 mounted.

  Furthermore, since the lower side portions of the overhang portions 100a and 100b of the sail 100 have an arc shape that swells upward, the forward view is prevented from being blocked by the lower side portion of the sail during sailing, and the visibility is ensured. it can.

  Thus, the sail 100 has the top outhaul 1, the clew outhaul 2, the bottom outhaul 3, and the groove 4, so that the existing sailboat hull 7 has a different shape from the conventional jib sail and spin sail. It can be used in equipment and facilities, and can be easily operated regardless of the skill level of the crew. Here, there was a saddle-shaped sale, but it was made of a very thin fabric such as parachute fabric, and it was never thought of being taken up by a take-up device or used as a jib sale that requires strength Met. The sail 100 can use the winding device 6 and can also be used as a jib sail.

(Embodiment 2)
FIG. 16 shows a second embodiment of the present invention. The difference between the second embodiment and the first embodiment is the shape of the lower part of the sail 110, and the other parts are the same as those of the first embodiment. Therefore, the description of the conforming part is omitted.

  The lower part of the sail 110 is formed by a straight line connecting the clew out hole 2 and the bottom out hole 3. The overhang portions 110 a and 110 b of the sail 110 are formed in a substantially triangular shape with the outer periphery surrounded by a straight line and symmetrical about the groove 4.

  The sail 110 having such a configuration is easy to process because the outer peripheral portion is formed by a substantially straight line.

(Embodiment 3)
FIG. 17 shows Embodiment 3 of the present invention. The third embodiment is different from the first embodiment in that the slits 120 c and 120 d are formed above and below the groove 4 of the sail 120.

  The sail 120 has overhang portions 120a and 120b separated by the groove 4 and the slits 120c and 120d. On the upper side and the lower side of the overhang portions 120a and 120b, a top outhole 1 and a bottom outhole 3 are provided, respectively. That is, the sail 120 has two top outholes 1 at the upper end and two bottom outholes 3 at the lower end.

  Thus, since the sail 120 has the top outhole 1 and the bottom outhole 3 at the upper end and the lower end of the overhang portions 120a and 120b, the sail 120 is securely fixed by the winding device 6, and the strong wind Even at times, the sale 120 can be prevented from shifting.

  Although the embodiments of the present invention have been described above, design changes and the like within the scope not departing from the gist of the present invention are also included in the present invention. For example, the groove 4 is not formed over substantially the entire length on a straight line connecting the top outhole 1 and the bottom outhole 3, but is formed below the top outhole 1 and above the bottom outhole 3. Each groove may be provided with a shorter length. Further, the groove 4 is mounted on the groove 61 of the winding device 6 in a state where the winding device 6 is rotated by approximately 180 ° so that the groove 4 is positioned on the outer surface (front surface in the traveling direction) of the sail 100. May be. In this case, at the time of sailing with the tailwind, the sail 100 projects outside the winding device 6.

  Further, when it is not necessary to wind up the sail during sailing, the groove 4 is not attached to the winding device 6 as shown in FIG. 18, and the bottom outhaul 3 is replaced with the bottom outhaul sheet (rope). 9 and adjusting the length of the rope 9, the height from the sea surface of the lower end of the sail 100 may be adjustable. In this case, even if the wind is a true chase, the sail 100 can be lifted high simply by unwinding the rope 9, so that it can be accelerated without complicated operations and can be sailed easily.

  Although similar sails have been devised, they do not have a shape that is intended to reduce the area of the take-up sail with a take-up device when there is a strong wind, etc. Since it has not been resolved to protect the sail, it has not been put into practical use and is not used. This sale can be easily installed on existing winding devices, and by solving this issue concisely, the sailing range and wind area of the yacht will be expanded and the marine industry will be encouraged.
