Definitions

  • Mast for boat or boat-like floating device in which the mast is, from a sideways tamable mounting in the boat's inner bottom hull, freely moveable along a fixed track which allows the mast to be angled in a sideways direction while the boat itself can remain in a virtually horizontal position.
  • Prior A ⁇ Modem boats with sail have one or more masts. These masts are statically fixed to the boat's superstructure and often to the cabin's rooftop. In some cases the mast reaches all the way down to the inner bottom hull of the boat and is statically fixed to both the bottom structure and to the top of the boat's superstructure. During, so called remasting the mast is lifted up, usually by a crane or equivalent and the mast is then fitted to an attachment preferably in the boat's superstructure. Remasting and demasting is necessary before and after the boating season. In regards to the masting of boats where the mast reaches all the way down to the bottom of the hull it is a question of more permanently fitted masts, where the masts are not removed before winter storage.
  • the mast is fixed to the boat without the ability to move.
  • the only mobility present is the mast's own elasticity, which allows the greatest flexibility at the top portion of the mast. This is quite normal because the mast has, toward the top, the least cross sectional diameter.
  • boom, the jib and the spinnaker that the sailor himself regulates. Sailing procedure requires hoisting the necessary sails for the type of boat to be sailed. Thereafter the boat must be maneuvered into an angel in which the sails are filled with wind. The most important thing is that optimal negative pressure is simultaneously created on the opposite side of the sail. This provides forward movement for the boat. Several procedures are needed to accomplish this.
  • the boat Because the mast is statically fixed to the boat, the boat must frequently be tilted to the side in order to harness the wind in the correct manner.
  • the boat's position in the water when heeled towards the side is also determined by whether the boat is round bottomed, has a so called keel or other weight or has another bottom design that, for example the optimist pram has.
  • the use of lead as a weight is not environmentally sound. But lead is often used because there is no alternative material or technique available. Sailors have problems avoiding deep lateral heeling. They hang on the outer side of the boat in an attempt to recreate balance and return rotation. Sometimes the sideways heel is too great causing the sail to dip into the water, thereby forcing the boat on its side, stopping further sailing.
  • USA 6,085,679 presents a control system for a sailboat's boom.
  • stay wires that run to and from the side edges of the boat for the purpose of increasing the possibilities for sailors to use them.
  • USA 5,231,943 puts forward a method for sailing where the sail's boom is able to rotate 360 degrees and where the boom's end avoids contact with at least one mast.
  • Sweden 9203862-9 presents a sailboat with a mast hinged to the upper part of the boat's superstructure.
  • Sweden 8503754-7 puts forward a mast that is hinged to the boat's superstructure and where control of the mast is accomplished with the aid of springs.
  • PCT/ES00/00235 presents a system for sailing where the boom rotates in combination with the boat's other equipment.
  • the boom rotates in conjunction with the rest of the boat's systems in the horizontal plane. Stretching of the sails is accomplished via vertical movements.
  • a self-conducted search has also been carried out in conjunction with the above stated technical search, and here it can be mentioned that even sailing methods such as windsurfing have been examined, where the mast, moveable to all sides, is fixed to the board's bottom part.
  • a hand held radially bent handle is used here to control the sail. Releasing hold of the handle means that the sail will fall down and lie on the board.
  • This invention aims to solve the problem of poor comfort that sailing entails.
  • the invention's pivotal aspect is that the wind itself should be the force that regulates the position of the sails and mast. Families and even other persons with minimal boating experience will often want to try there hand at and practice sailing. But the demands on the sailor that he or she should have knowledge about and actively be able to adjust sails and boat position for all sailing conditions has resulted in fewer people learning to sail. Thus the market demands new technology for sailboats. A need has been voiced that sailboats should contain more automatic solutions, whereby the sailboat under operation is able to adjust itself after the situation. With todays ever increasing energy prizes this is a societal problem that must be solved.
  • the main technical problem is to provide a technical solution where the wind regulates the sail and the position of the mast.
  • the time required to learn this skill does not exist and as mentioned above the market demands new solutions to current technical problems.
  • Another problem associated with the main problem is the question of which routines the sailor should have in order to use this technology.
  • Current technology requires a large amount of know-how and a long period of learning with training to develop the abilities necessary to master the skills sailing requires. It is known that it is only those who sail often and receive the best instructions that become skillful sailors. A new technology would in a substantial way influence the development of sailing in a greatly positive manner.
  • the technical problem within this invention should therefore be solved by technical solutions and procedures thereof.
  • the solution to the technical problem is comprised of the mast reaching all the way down to the boat's (1) inner bottom hull.
  • the mast (4) capable of sideways movement (18', 18")
  • this movement is regulated via a track (15) in the boat's (1) superstructure.
  • the before named track (15) is placed, which allows the mast (4) sideways movement (18', 18"), preferably with the aid of a glide and roll track (15).
  • the glide and roll track (15) has at least two surfaces against which the mast's glide or roller bearings, preferably comprised of wheel-type rolls (17', 17"), regulate the mast's (4) sideways movement. These two surfaces can in exceptional cases be comprised of only one track with a corresponding wheel on each side. This will be presented in the special description.
  • the track's technical solution can therefore be comprised of one, two or more tracks (15). With the mast's (4) lower end attached (12) to the boat's (1) bottom hull as an origin, the glide and roll track (15) stretches like part of a circle's circumference from one of the boat's side edges (13) to the opposite (14) side edge with approximately the same radius. Variations can be found here and these will be presented in the special description.
  • the exposed glide and roll track (15) from the one side edge (13) to the opposite side edge (14).
  • a strip-like device of rubber, polymer or other suitable material This strip or strips follows the mast's (4) sideways movement and opens as well as closes the opening that arises in order to make room for the mast (4).
  • the so called support stays from the boat's sides are removed by this technical solution. Only support stays from the bow (6) and the stem (9) are present.
  • the mast (4) is instead extended from the cabin roof to a mast step (12) in the hull's inner bottom area, which is described in several places in the text of this patent application.
  • the wind's regulation of the mast's (4) position is guided by at least two very strong wire-like cords (6, 9).
  • One of these (6) runs from the bow to a pulley at the top of the mast and one (9) runs from the stern to another pulley at the top of the mast (4).
  • the pulleys placed at the top (8) of the mast which angle the cords (6, 9) downward are preferably attached to a holding fixture (28).
  • These pulleys or wheels are separated from and work independent of each other and are structurally very strong. Of coarse there are for example even other pulleys for sails.
  • the wire-like cords (6, 9) then run from the pulleys in the mast's top along the mast, preferably in protective pipe-like devices (25', 25"), down to separate weights (26, 27) for each cord, which provides support for the mast (4) and also prolongs the time-wise length of the mast's (4) movement. This in itself reduces strain on the mast (4) and the boat (1) according to the known "force times time” equation. In this way the mast (4) can not be broken which is very important.
  • weights (26, 27) are preferably placed in vertical movement under the glide and roll track (15).
  • the very strong wire-like cords (6, 9) from the bow (7) and the stern (10) support the mast (4) and work indirectly in conjunction with weight (24).
  • the slider (16) which is mounted to the mast's (4) lower part under the boom (29) at the same level as the so called track (15), that is the glide and roll track (15), also has a wire-like cord (20) that runs from this slider (16) to the named weight (24).
  • the wire-like cord (20) must run over at least two oppositely faced in the horizontal plane lying guided pulley-like wheels (22', 22"). This is due to the fact that the mast (4) moves in both directions (18', 18"). This wire-like cord (20) always leaves the mast's (4) movement track (15) at the same point, this is between the so called guided pulley-like wheels (22', 22"). From the guided pulleylike wheels (22', 22") the wire-like cord (20) runs over another pulley (23) down to the hanging weight (24).
  • This weight (24) counterbalances both of the mast's (4) sideways movements (18', 18") in the track (15) and in contact with the glide or roll track (15).
  • the weight's (24) movement is almost entirely vertical.
  • the invention's technical novelty lies in that it is the wind in itself that regulates the sail and mast position. This gives the sailor more time to engage in other elements. Currently it is the sailor himself that for the most part regulates this. It is therefore possible to define the routines of the sailor as follows. The sailor hoists the sail and can thereafter either sail with a stationary mast, which today's technology provides or alternatively sail according to this new invention by freeing the mast (4) so it can move sideways.
  • the sailor can of coarse during sailing alternate freely between these alternatives.
  • the freed mast (4) moves in a track in contact with the glide or roll track (15) and adjusts itself after wind conditions.
  • Wire-like cords (6, 9) from the bow (7) and the stern (10) run over the pulleys at the top (8) of the mast and then run along the mast (4), preferably in the before named protective pipe-like devices (25', 25"), down to the mast's (4) lower end where the wire-like cords (6, 9) receive aid from their respective weights (26, 27), called balancing weights (26, 27) for the purpose of balancing the mast's (4) position.
  • this invention provides a technique where the wind regulates the sail (5', 5") and mast position.
  • This is achieved through the use of a sideways shiftable (18', 18") movement track (15) for the mast (4). This may lead one to believe that the movement track (15) will be very large. But if it is taken into consideration that the mast (4) will be pivotally moveably attached and mounted (12) to the boat's (1) inner bottom structure, the angular deflection will be limited. But the technical effect will still be great.
  • the mast (4) stretches from its sideways moveable step (12) in the boat's inner bottom hull up toward and through the boat's superstructure.
  • the distance from the mast's (4) step in the hull's bottom (12) to the boat's sides (18', 18"), that is the glide or roll track's (15) outer edges (18', 18"), implies that from a central vertical plane the angular deflection will be less than 45 degrees, preferably 25-35 degrees.
  • the mast (4) then continues up to its full length. Even open boats (1) without or with limited superstructures will be discussed in this document's special description area.
  • the movement track (15), that is the glide or roll track (15) is placed freely between the boat edges (18', 18").
  • This track can of coarse be built into a bracket or protected by strip-like or other similar devices.
  • the market that offers many types of smaller boats such as rowboats, motorboats, motor sailboats, etc. demands improved optional equipment for these boats so they can be operated as sailboats. This technology provides this.
  • the advantages of a sideways moveable mast (4) mounted to a step (12) implies, in summary, the below;
  • this invention presents a boat for the whole family. Both young and old that currently have difficulty sailing due to the boat's abrupt and steep heeling can with this design continue sailing. Even during strong winds this invention makes it is possible to consume meals relatively undisturbed by wind and heeling. prevents the mast (4) from breaking off. that the so called heel, when the boat (1) is thrown to the side by the wind is at the least reduced. It is often this occurrence that causes persons to be injured or thrown overboard, in other words increased safety.
  • the keel (11) comprised of environmentally hazardous lead can be removed or at the least be radically reduced, that remasting and demasting of the boat can be accomplished manually, that the mast (4), the sail (5', 5"), the boom (29) and the fore- as well as the backstay (6, 9) are found above deck.
  • the weights (24, 26, 27) and their wire-like cords are adjusted depending on the boat type (1), mast length (4), sail or similar. Bruises and contusions are prevented by the weights (24, 26, 27) being placed under deck, even to be able to offer the market a semi-finished product which allows the sailor himself to overhaul an existing boat in accordance with this invention's technique. that the named semi-finished product integrates a pedagogical model, a method, for learning to sail.
  • a secondary effect of this technology is for example that it can be utilized, as mentioned above, for remasting of boats (1).
  • Today cranes are used to lift the mast into place.
  • This technology makes it possible to manually remast a boat from a quay birth thanks to the mast's (4) and the boat's sideways mobility.
  • This also allows for the repair of masts (4) and the replacement of pulleys and the like in a safe manner from a quay birth. For example, it is not necessary to climb up onto the mast or to use a crane.

Abstract

Un mât mobile (4) est fixé au fond intérieur de la coque d'un bateau (1) par l'intermédiaire d'une emplanture mobile latéralement (12). Le mât (4) s'étend vers le haut à travers le pont ou la cabine dans le cas où il en existe et il s'élève approximativement aussi haut que la technologie actuelle le permet à un mât classique (4). La mobilité latérale ayant l'emplanture (12) comme origine constitue un rail de glissement et de roulement de forme arquée (15). Le mât (4) comprend des cordages de type haubans depuis la proue (6) et la poupe (9), lesquels passent sur le haut (8) du mât (4) par des poulies (24, 25) et descendent jusqu'à des poids (26, 27). Leur rôle est d'équilibre le mât (4). Le mât (4) présente aussi un autre cordage de type hauban (20) lequel est fixé à une patte (21) située sur la coulisse (16) au niveau de la partie inférieure du mât (4). Le cordage (20) s'étend à partir de la patte (21) entre deux poulies horizontales (22', 22''), ce qui signifie que le cordage (20) se trouve toujours dans la même position d'entrée quelle que soit la distance que parcourt le mât sur la gauche (18') ou sur la droite (18''). Le cordage passe à partir de ces poulies (22', 22'') jusqu'à une autre poulie (23) donnant au cordage (20) un angle descendant jusqu'au poids (24), lequel équilibre le mât (4). Le vent et les poids régulent la position du mât (4) et donnent ainsi au bateau (1) une position horizontale plus correcte. Le procédé, selon l'invention d'utilisation de l'invention, commence par une libération du mât (4) qui peut alors, à l'aide du vent, se réguler automatiquement dans différents angles. Le marin a la possibilité de naviguer alternativement d'une manière classique avec un mât fixé statiquement (4) ou de libérer le mât (4) ce qui le rend mobile latéralement (18', 18''). Cette nouvelle technologie assouplit les conditions de navigation nécessitant une véritable connaissance de la navigation du fait que le vent lui-même règle le mât (4) sur l'angle correct. De la façon précitée, le bateau garde une position horizontale optimale. En conséquence ceci offre un niveau sensiblement supérieur de confort pendant la navigation à la voile.
