Definitions

  • the present invention relates to a sail board arrangement, the sail of the board comprises a first and a second sail section with an air gap therebetween, and the sail sections are individually stretched between an associated mast and an associated boom with a pocket formation in each sail section.
  • An arrangement of the above stated art is known from Norwegian patent application 83 3673. It is shown a sail board arrangement, wherein the sail of the board comprises two sections. A first section is in form of a fore sail and a second section is in form of a storm sail. Each of said sail sections is secured by its leading edge to its associated mast.. By means of a s.tretching device each sail section is secured at its opposite edge to one end of its boom, whereas the opposite end thereof is secured to its associated mast.
  • An active mast is being secured directly to the board by means of a flexible fastening member at the lower end of the mast, whereas an inactive mast or a similar bracing member is secured directly to the active mast.
  • An arrangement of two sail sections (fore sail and storm sail) is illustrated therein, each of which may be secured to a separate mast extending next to each other, whereas one of the masts (to which the fore sail is secured) provides the active mast, and the other mast (to which the storm sail is secured) provides an inactive mast or auxilliary mast.
  • active mast is herein being meant the mast that is connected directly to the sail board by means of an associated fastening member
  • active mast is being meant the mast that is fastened directly to the activemast without further connection with the sail board.
  • One of the sail sections (the storm sail) of prior art is adjustable in different angular positions in relation to the other sail section (the fore sail) by swinging said one sail section about its associated mast.
  • DE OS 31 21 402 Al is shown a sail board with two sail sections secured to a common mast.
  • the fore sail is secured with one of its edges to the mast and with the opposite edge secured by means of a stretching arrangement to the outer end of a boom that is a common boom for said two sail sections.
  • the storm sail is secured at the upper and lower end of the mast and by means of one of its edges it is adapted to be stretched in a certain degree such that a gap is provided along the mast.
  • said storm sail is stretched from the top of the mast to the outer end of the boom and from the outer end of the boom to th'e lower portion of the mast.
  • a front pocket formation is provided in the storm sail and a rear pocket formation is provided in the fore sail to allow air to pass in a restricted air stream through said gap between the mast and the storm sail and accordingly, in a favourable manner between the sail sections.
  • a favourable propulsion effect is obtained in a similar way as by sailing a sail boat provided with fore sail and storm sail.
  • a disadvantage of the embodiment of prior art according to said DE OS 31 21 402 Al is, that the storm sail is not sufficiently controllable and among other things has a tendency to flutter upon turning of the sail board. Accordingly, during sailing possible adjustment of the storm-sail is minimized.
  • Another disadvantage consists in the difficulties in turning the sail board provided with such unregulatable amount of sails and such rigid and unflexible sail structure as shown in the prior art embodiment. In said prior art embodiment it is difficult or even impossible for the user of the sail board during movement of the board to pass in front of the mast.
  • the aim of the present invention is to provide a solution, wherein pocket formations are obtained in a controlled manner in both sail sections and simultaneously to allow a restricted air stream to pass in controlled and regulatable manner between the sail sections. Also, there is sought to provide a solution, wherein the user is allowed to pass in front of the mast during turning of the board.
  • the arrangement of the present invention is characterised in that said first (front) sail section with its forward edge is connected direct to the mast whereas said second (rear) sail section with its front edge is connected to the mast by means of a bracing member, which in its turn is connected to the mast or said first sail section at the upper or lower end of same, and that the rear side edge of said first sail section is movable from side to side in said boom arrangement in front of and sideways past the leading edge of said second sail section in order to adjust said air gap from side to side in relation to " said second sail section in order to guide an air stream from said first sail section through said air gap obliquely rearwards and outwards along the leeward side of said second sail section.
  • the arrangement is characterised in that said first sail section is turnable about its leading edge within a first boom, whereas said second sail section is turnable about its leading edge within a second boom and said second boom is adjustable and fixable in certain angular positions in relation to said first boom about an axis extending rectangularly to the maine plane of the boom.
  • a boom which is a common boom for said sail sections, is provided with a bracing portion extending transversely of the boom in the central portion thereof, and by preference closer to the front end than to the rear end of the boom, whereas the rear edge of said first sail section is slidably engaged with one of the side edges of the bracing portion, and the leading edge of said second sail section is secured to or slidably connected to the other side edge of said bracing portion.
  • a common boom for said sail sections by using a common boom for said sail sections, it is in general terms achieved a simple boom structure and a simple rigging of the sail sections, simultaneously as one may omit said second mast, which is required in other respects, or said second mast is in all events allowed to have a simple, especially flexible and easily mountable structure.
  • said bracing portion extending transversely of the boom, it is possible in a simple manner to secure an efficient fastening of the sliding means at the rear edge of said first sail section, and simultaneously secure an efficient fastening of the leading edge of said second sail section, and accordingly, provide a controllable air gap between the sail sections, in all events in the neighbourhood of the boom.
  • Figs. 1 and 2 show a sail arrangement of the invention in side elevation and show alternative ways of fastening the sail arrangement in the sail board.
  • Fig. 3 is a horisontal sectional view of the sail arrangement according to Figs. 1 and 2.
  • & Figs. 4 and 5 show a detail of means for fastening the masts in certain mutual angular positions, illustrated in a side elevation respectively in a horisontal sectional view.
  • Fig. 6 shows the arrangement of the invention in a second embodiment thereof, illustrated in a side elevation.
  • Fig. 7 shows a horisontal sectional view of the arrangement of Fig. 6.
  • Figs. 8 and 9 show a first and second section of the arrangement of Figs. 6 and 7 to a greater scale.
  • Fig. 10 shows a side elevation of the arrangement of the invention according to a third embodiment thereof.
  • Fig. 11 is a horisontal sectional view of the arrangement of Fig. 10.
  • Fig. 12 is a vertical sectional view of the arrangement of Fig. 11.
  • Fig. 13 shows an alternative embodiment of a detail of fig. 11.
  • FIGs. 1 and 2 there are shown a sailing board 10 to which one and the same amount of sails is mounted on a sail board in two different ways.

Abstract

Agencement de planche à voile, dans lequel les voiles de la planche à voile comportent une première (12) et une deuxième (14) partie de voile avec un écartement aérodynamique intermédiaire. Lesdites parties de la voile sont tendues entre un mât associé (11) et un agencement formé d'un bout-dehors (16), une poche étant créée dans chacune des parties de voile. Ladite première partie (avant) de voile (12) avec son bord d'attaque est reliée directement au mât (11), tandis que la deuxième partie (arrière) de voile (14) avec son bord d'attaque est reliée au mât par un moyen de renforcement (13) qui à son tour est relié au mât. Le rebord arrière de ladite première partie de voile (12) peut se déplacer d'un côté à l'autre à l'intérieur de l'agencement du bout-dehors devant et au-delà du bord d'attaque de la deuxième partie de voile de manière à régler l'écartement aérodynamique d'un côté à l'autre par rapport à ladite deuxième partie de voile. Ainsi un écoulement d'air peut être guidé depuis ladite première partie de voile à travers l'écartement aérodynamique en suivant une trajectoire transversale vers l'arrière et vers l'extérieur, le long du côté qui est sous le vent de ladite deuxième partie de voile.
