Definitions

  • This invention relates to an apparatus for propelling a boat or the like.
  • Exploitation of the wind as a primary driving force is done with the use of cable and sail systems which, anchored by means of one or more vertical or horizontal masts, capture the energy necessary to move the vessel.
  • sailing with sails is today an exclusive pursuit of those who have already acquired or have the means to acquire a certain familiarity with the complex manoeuvres and equipment necessary for exploitation of the wind.
  • traction sails on motor boats leads to a reduction in the consumption of fossil fuels. Thanks to the constructional and functional simplicity thereof, these sails can be used on any boat and by any user; known traction sails do not require specific nautical competence in order to be used.
  • the sail is flexible, the drop into the water means loss of functionality for a certain period of time, due to the increase in weight of the sail and the ensuing difficulty of re-using the soaked sail. If the sail is rigid, there are however some complications inasmuch as it is necessary to stop the boat, drag the equipment on-board and get it back into working condition.
  • the first stages of use of traditional traction sails e.g. launching, are often awkward as they require a preparatory state in which the sails have to be brought up to working height; the difficulty of these manoeuvres lies in the fact that the wind, in the first metres of rising from the ground or the water surface, is not constant but includes turbulence which makes getting the sail up to working height difficult.
  • the main aim of this invention is to provide an apparatus for propelling a boat or the like which enables traction sails to be used while prevent them from falling into the water even in conditions where there is not sufficient wind or where a wrong manoeuvre has been made.
  • a further object of this invention is to provide an apparatus which can be supported by any boat whether it is a motor boat, i.e. functioning as an auxiliary sail, or a non-motorised boat, i.e. in which it functions as a primary or secondary sail.
  • a further object of this invention is to simplify the sail preparation operations, such as to reduce the time required to make it functional.
  • a further object of this invention is to provide an apparatus which is suitable to be used with both flexible and rigid sails.
  • a further object of this invention is to make sailing more comfortable, enabling displacement of the aerodynamic thrust centre to the hydrodynamic thrust centre of the boat.
  • a further object of this invention is to provide a light apparatus which is also not an encumbrance and can be easy to transport and mount.
  • a further object of this invention is to allow contemporaneous use of two or more sails at the same time, increasing the aerodynamic force thereof.
  • a further object of this invention is to provide an apparatus for propelling a boat or the like which enables the above-mentioned drawbacks in the prior art to be obviated in the ambit of a simple, rational solution which is easy to use and relatively inexpensive.
  • this apparatus for propelling a boat or the like of the invention characterised in that it comprises at least a base associable to a boat, at least a support element having a substantially elongate conformation which is also substantially rigid and provided with a first end which is associable to said base rotatable about at least a rotation axis and a second end which is associated to aerodynamic means for drawing said boat, and at least a drawing element associated to said aerodynamic means and to at least one from said boat, said base and said support element.

  • 1 denotes in its entirety an apparatus for propelling a boat or the like.
  • the apparatus 1 is suitable to be used on a boat 2 of any size, whether a motor boat or a sail boat.
  • the apparatus 1 is made up of a base 3, associable to the boat 2, a support element 4 associated to the base 3 and suitable for supporting aerodynamic means 5 for drawing the boat 2, and a plurality of drawing elements 6 of the aerodynamic means 5.
  • the base 3 consists of an anchoring portion 7 to the boat 2 and a support portion
  • the anchoring portion 7 is associated to the boat 2, e.g. by welding, using screw means, or by interlocking, or other suitable methods for retaining, also removably, the base 3 on the boat 2.
  • the anchoring portion 7 advantageously comprises a guide 9 and a slide 10 on which a support portion 8 is mounted, the slide 10 being movable along the guide 9.
  • the displacement of the slide 10 in the guide 9 enables the point of application of the traction force deriving from the aerodynamic means 5 to be moved, which traction force acts on the boat 2; in particular, the aerodynamic thrust centre (the point at which the aerodynamic forces are concentrated) can be displaced to the centre of the hydrodynamic thrust centre (the point where the forces deriving from the hull immersed in the water are concentrated), stabilising the boat 2 and making navigation more comfortable.
  • the support portion 8 is located on the slide 10 and is formed by two plates or walls 11 which are vertical, facing, parallel and distanced.
  • the two walls 11 are rotatably associated to the anchoring portion 7 by interposition of a vertical first pivot 12 which is rotatable about an axis thereof.
  • the support portion 8 could also be realised, e.g., with a single wall 11 or the like.
  • the support portion 8, and consequently the support element 4 associated thereto, usefully rotates on the first pivot 12 about a first vertical rotation axis
  • the base 3 therefore has reduced size and weight which make it portable so that transport and use thereof on various boats are possible; however, the apparatus 1 can be unremovably installed on the boat 2 during the stage of building the boat
  • a connecting element 13 for the support element 4 is housed rotatably between the two walls 11 of the support portion 8.
  • the support element 4 is integrally coupled to the connecting element 13 at a first end 14 thereof; the opposite end, associated to the aerodynamic means 5, is therefore denoted as the second end 15.
  • the connecting element 13 is hinged rotatably to the two walls 11 at a horizontal second pivot 16.
  • the connecting element 13, and therefore the support element 4 rotates about a second horizontal rotation axis O identified by the second pivot 16; the first end
  • the first end 14 is advantageously rotatable about the two axes V and O, which are transversal to one another and which enable the support element 4 to be orientated in any direction in space; in particular, the first and the second rotation axes V and O are respectively identified by the first pivot 12 and the second pivot 16.
  • the rotation of the support element 4 can also be obtained with a spherical joint or the like; this solution constitutes an alternative embodiment of the base 3 which is however equivalent to the one already described.
  • connection element 13 is provided with an elongate section which is snugly insertable internally of the first end 14 of the support element 4.
  • the coupling between the connecting element 13 and the support element 4 can be done e.g. with interlocking means which allow free or partial rotation of the support element 4 about the longitudinal axis thereof.
  • the association between the connecting element 13 and the support element 4 can be made using a terminal section of the support element 4 which is insertable in a respective housing on the connecting element 13.
  • the connecting element 13 thus constitutes a prolongation of the first end 14 of the support element 4.
  • the connecting element 13 is made of a polymer material in order to give greater lightness to the apparatus 1 ; the use of other materials such as wood and metal is not however out of the question.
  • the support portion 8 further comprises regulation means 17 for regulating the orientation in space of the support element 4 with respect to both rotation axes V and O.
  • the regulation means 17 comprise first blocking means 18, suitable for blocking the rotation of the support element 4 with respect to the first rotation axis V, and second blocking means 19, suitable for blocking the rotation of the support element 4 with respect to the second rotation axis O.
  • the combined action of the first and second blocking means 18 and 19 leads to blocking the support element 4 in a determined position with respect to the boat 2, which is established by the user in order to optimise the performance of the apparatus 1 on the basis of the route of the boat 2 and the direction of the wind.
  • the first and second blocking means 18 and 19 consist in a pair of levers associated respectively to the first and the second pivots 12 and 16, which are manually activatable and moveable between an open position, in which the rotation of the support element 4 about the first rotation axis V or the second rotation axis O is free, and a locked position, in which the rotation of the support element 4 about the first rotation axis V or the second rotation axis O is blocked.
  • the movement of the lever from the open position to the locked position activates a blocking mechanism, e.g. of the friction type, cogwheel type or other.
  • the regulation means 17 also comprise a first stop element 20 which stops the rotation of the support element about the second rotation axis O at a maximum inclined position, and a second stop element 21 of the rotation of the support element with respect to the second rotation axis O at a minimum inclination position.
  • the first stop element 20 consists in a bar arranged between the two walls 11 which bar is transversal to the support element 4; in particular, the first stop element 20 is located at a point comprised between the second end 15 and the second pivot 16 and superiorly with respect to the connecting element 13.
  • the connecting element 13 When it rises together with the support element 4 due to the wind's action, the connecting element 13 goes to strike against the first stop element 20 which thus defines a maximum rise angle.
  • the second stop element 21 consists of a bar arranged between the two walls
  • the second stop element 21 is located at a point comprised between the second pivot 16 and the first pivot 12 and superiorly with respect to the connecting element 13.
  • This position of minimum inclination advantageously prevents the support element 4 from lowering beyond the predetermined angle, at which the aerodynamic means 5 would fall into the water.
  • the maximum inclined position prevents the aerodynamic means 5 from moving onto the vertical of the support element 4, where the traction force would be annulled.
  • the support portion 8 could be provided with third blocking means of the rotation of the support element 4 with respect to the longitudinal axis thereof, such as to optimally regulate the position of the aerodynamic means 5.
  • the base 3 could be provided with stop elements of the rotation with respect to the first vertical rotation axis V, in order to prevent any inversions of the direction of the aerodynamic means in a case of turbulent gusts of wind.
  • the support element 4 is shaped like a tubular element and is made of carbon fibre or another rigid and resistant material such as e.g. metal, glass, ceramic, or polymer resins, to prevent undesired flexions or distortions.
  • the support element 4 can usefully be realised telescopically, in a single piece, or be constituted by modules which can be assembled to reduce the size thereof when not in use.
  • the support element 4 For a boat 2 having an approximate length comprised between 4 and 6 metres, the support element 4 has an approximate length comprised between about 5 and 15 metres, and a section comprised approximately between 30 and 70 mm.

  • the second end 15 of the support element 4 is associated to a stiffening element 22, substantially elongate and mounted on the aerodynamic means 5.
  • the stiffening element 22 is a bar associated perpendicularly to the support element 4, which reinforces and stiffens at least a fraction of the surface of the aerodynamic means 5.
  • the aerodynamic means 5 are, in the two embodiments illustrated in the figures, flexible sails 23 or rigid wings 24.
  • the aerodynamic means 5 can be represented as a plurality of flexible sails 23 or rigid wings 24 mounted in series.
  • the flexible sails 23 are preferably of the type used in paragliding.
  • the flexible sails 23 comprise one or more aerodynamic features known to experts in the field, such as e.g. two parallel layers of cloth, inlet mouths for the air on the front side, elongate conformation, presence of internal struts and lateral stabilisers, optimal camber.
  • the rigid wings 24, on the other hand, have a winged profile for improving the aerodynamic functions, and can be provided with stabilisers, flaps, anti-vortex slats, etc.
  • the stiffening element 22 consists of a carbon fibre rod passing through a plurality of eyelets 24 located on the lower surface of the wind-exposed side of the sail 23; the section of the carbon fibre rod decreases in a direction towards the ends in order to lighten the weight of the aerodynamic structure.
  • the stiffening element 22 has the function of always completely maintaining the sail surface unfurled to the wind, preventing it from wrinkling up and losing efficiency.
  • the stiffening element 22 of a rigid wing consists in a beam which runs along the wing length and increases the wing's resistance to stress.
  • the association between the second end 15 of the support element 4 and the stiffening element 22 is guaranteed by a joint element 25.

  • the second section 27 is provided with at least a partial housing channel 29 of the stiffening element 22.
  • the third section 28, interposed between the two sections 26 and 27, is a flexible joint, e.g. made of rubber, which enables the stiffening element 22 to be statically unconstrained to the support element 4.
  • the apparatus 1 supports more than one rigid wing
  • a support carriage for the aerodynamic means 5 is usefully provided, slidably associated along the support element 4.
  • the carriage properly controlled, enables the aerodynamic means 5 to be unfurled from the first end 14 of the support element 4 up to the second end 15, before using the apparatus 1.
  • the carriage can be controlled manually or using automatic means and, e.g., can be provided with specially-shaped wheels and mounted on the support element.
  • the drawing elements 6, which consist in a series of traction cables, are suitable for supporting the drawing force exerted on the aerodynamic means 5 and transmitting it to the boat 2.
  • the drawing elements 6 are retained at a first end thereof to the aerodynamic means 5, and at the second end thereof to a sliding element 30 mounted on the support element 4.
  • the sliding element can be mounted on the connecting element 13.
  • the sliding element 30 is, in the special embodiment illustrated in the figures, a sleeve provided with holes in which the drawing elements 6 are inserted.
  • the sliding element 30 is blocked at a desired distance from the base 3 by anchoring means 31.
  • the anchoring means 31, of known type in the nautical field consist, e.g., of a cable having an adjustable length which defines the distance between the sliding element 30 and a fixed point arranged on the support element 4.
  • Other embodiments are possible too, in which the fixed point is located on the base 3 or on the boat 2.
  • the drawing elements 6 also have a regulating function on the aerodynamic means; in particular they modify the sail surfaces and the incidence thereof with respect to the wind. Alternatively, other elements for modifying and controlling the trim of the aerodynamic means 5 might be different from the drawing elements 6.
  • the apparatus 1 of the invention functions as follows.
  • the apparatus 1 is installed by means of screws or the like on the boat 2, in a position which makes it easy for the user and which affords the necessary room for manoeuvre.
  • the stiffening element 22 maintains the front face thereof exposed to the wind well spread, such that by gaining lift the flexible sail 23 rises and lifts the support element 4 too; thus, advantageously, the apparatus 1 has no need of support cables for the aerodynamic means 5.
  • the position of the support element 4 during use is fixed manually by the user on the first and second blocking means 18 and 19, which adjust both the inclination and the direction of the support element 4.
  • the blocking means 18 and 19 might, during sailing, be kept in the position in which the rotation of the support element 4 is free, thus enabling positioning of the flexible sail 23 in the direction imposed by the wind.
  • the aerodynamic means thus transmit the traction force to the boat 2 by means of the drawing elements 6.
  • the traction force is obtained by the passage of the wind on the surfaces of the aerodynamic means 5, when the wind is at least partially aligned to the boat's 2 direction of progress. No particular attention or maintenance is required for the apparatus 1, as the support element 4 prevents the aerodynamic means 5 from falling in the water and snagging on the boat.
  • the invention has been seen in practice to reach the set objects.
  • the support element prevents the sails from falling in the water even where a wrong manoeuvre is carried out, or there is no wind, and thus prevents the need for getting the sail out of the water and drying it, operations which are not easy and indeed make the use of traditional drawing by aerodynamic means inconvenient.
  • the stiffening element provided on the aerodynamic means is particularly useful in a case in which flexible sails are used, since they facilitate correct exposition of the sail to the wind and its correct filling and functioning. Also worthy of note is that since the apparatus is small in size and the support element can be telescopic, transport and use of the apparatus are particularly easy, even on small boats.
  • the use of the apparatus ranges over all type of boats, from sailing boats, in which it can support a sail in primary or secondary use, especially to motor boats, where the aerodynamic means provide an auxiliary thrust which contributes to limiting costs and use of fossil fuels.
  • a further advantage of the invention is the special arrangement of movable slide in the guide which facilitates easy movement of the aerodynamic thrust centre, such as to be able to position it at the hydrodynamic thrust centre and make sailing more comfortable; this detail reduces or eliminates the formation of torque responsible for tilting the boat during sailing.
  • a further very positive point is the high efficiency of the apparatus thanks to the fact that it is possible to exploit the traction force of a plurality of superposed sails or wings, thus increasing the traction force while maintaining a single support element installed on the boat.
