Definitions

  • the present invention refers to a mast for sailing boats, applicable both to recreation and to competition crafts, and to sailing merchant ships of any tonnage whatsoever, improving the performance of the mainsail.
  • the object of the invention is to prevent the described problems by means of a mast which presents side surfaces which create a minimum resistance against the wind when it is a headwind, whilst on the contrary, when it is a tailwind, the mast offers an opposed surface to the action of the wind, which adhers to the surface of the mainsail.
  • the profile toned by the mast is of triangular section, with at least two of its walls being equal, and which extend transversally, as from the third wall into sections of equal length which delimit divergent wings, as from said third wall,
  • the third wall which remains partially retracted as regards the other two, is provided with moveable means of fastenings for the sail, which permit the horizontal displacement of the sail along the width of said third wall.
  • the tubular profile has an isosceles triangular profile, the two equal walls preferably having slightly convex curved cross section.
  • the means of fastenings for the sail may consist of locks or connections which run between the third wall of the tubular mast and the sail, said means including at least one articulation joint, parallel to the tubular profile.
  • the fastening means may consist of a rod which is connected at one end to the third wall of the tubular profile which forms the mast, whilst at the opposed end the sail is connected by means of a shaft articulation joint to the tubular profile.
  • the third wall of the profile of the mast can be provided with a transversal groove through which the rod may pass through and move, and which remains retained by means of a internal widening or stop of said rod.
  • the boom consists of a tubular profile in which the wall directed towards the sail, shall be of flat configuration.
  • Said wall is provided with transversal grooves or runners to which it is connected and along the length of which, the sail locks can move.
  • the mast of the invention permits the obtention of a greater service, since the third wall of the tubular profile of the mast is transformed into an extension of the surface of the mainsail.
  • the mast 3 is of tubular section and adopts, as can be better observed from figures 3 and 4, an isosceles triangular shape, the equal walls 5 of which, are of slightly convex curved cross section and may extend from the third wall, referenced with number 6, with portions of equal length which determine divergent wings 7.
  • the sail 2 is connected to the third wall 6 of the mast 3 by means of moveable fastenings which permits the left-to-right displacement of the attachment points of the sail 2 to the mast, along the width of said wall 6.
  • the moveable fastening may be constituted by a rod 8 which, such as is shown in figure 3, can be inserted through a transversal groove 9 of the third wall 6, the rod being finished off at the internal end into a head 10 of greater diameter than the width of the groove 9, so as not to permit its exit, but permitting the displacement of rod 8 along the length of groove 9.
  • rod 8 is attached to the sail 2 by means of an articulation joint 11.
  • Figure 4 shows an embodiment variation in which attached on the exterior of the third wall 6 of the mast 3 are transversal plates 12, on which grooves 9' are performed, to which the rod 8 is connected in like manner to that described with reference to figure 3.
  • Figure 5 shows embodiment variations of the fastening which connects the sail 2 to the mast 3.
  • fastenings may be constituted by a part 13a, 13b, 13c which is attached to the third wall 6 of the mast, by means of welding or threading.
  • a journalled arm 15a-15b-15c is connected in articulation, which may adopt any configuration and is finished off into a strip 16 or sleeve 17 for the attachment of the sail.
  • FIGs 3 through 5 only show possibilities of connection between the sail and the mast, which meet the characteristics of permitting the movement of the connection points of the sail to the mast in horizontal direction, widthwise to the third wall 6 of the tubular profile which forms the mast.
  • the boom 4 shall also be preferably constituted by a tubular profile which shall at least present an upper flat wall 18, directed towards the sail 2.
  • Said wall 18 shall be connected to the sail so that the connection points can be transversally displaced as regards the boom 4.
  • wall 18 may be provided with transversal grooves 19, of decreasing length as they move away from the mast 3, to which the sail 2 shall connected by means of rods 20 of like characteristics to rod 8, figures 3 and 4, which connect the sail to the mast.
  • Figure 6 shows the position adopted by the sail, as regards the mast 3, with a headwind.
  • the connections of the sail 2 to the mast 3 are transversally displaced as regards said mast, the external surface of the sail remaining as an extensionn of one of the walls 5 of the mast 3.
  • a continuous aerodynamicc plane is obtained, permitting the air to circulate through the extrados of the sail without encountering any obstacle.
  • Figure 8 shows the relative position of sail 2, in relation to mast 3, with a tailwind,
  • the wind shall influence perpendicularly the third wall 6 of the mast 3, acting on the same with improved effect, due to the existence of the wings 7 which limit wall 6.
  • the surface of wall 6 constitutes an increase of the surface of sail 2, with which an improved use of the action of the wind is achieved.
