Definitions

  • the present invention relates to reefing or furling booms for sails.
  • Prior art reefing or furl,ing booms work on the principle of winding the mainsail onto which is connected to the mast by a pivotal (usually universal) connection. This single connection has been found to be difficult to operate.
  • One modification as shown in U.S. Patent 4 324 192 has required the sailtrack on the back of the mast to be displaced rearwardly by the interposing of a clothweb so that the boltrope of the luff wraps around the rotary member aft of its gooseneck. The mast sailtrack thus simply flaps about when the sail is reefed which is an unsatisfactory situation.
  • the present invention provides a reefing or furling boom for connection to a mast of a sailing boat, which comprises a rigid boom adapted to be connected to the mast at one end by a double-acting swivel joint; a rotatable roller to which the foot of a sail may be attached so as to allow the sail to be wound onto the roller.
  • a double-acting universal joint being mounted at one end of the roller and being adapted to be connected to the mast at a position 'spaced above the swivel joint, tensioning means on the roller for tensioning the foot of the sail, means interconnecting free ends of the boom and the ro ll er such that the boom and roller are constrained to swivel together, and rotation means to rotate the roller; t h e arrangement being such that the mast end of the sail ca ⁇ be wound onto the roller without substantial deviation from the line of the mast.
  • the boom is rigid in the sense that it should be able to take the loadings normally placed on a boom.
  • the boom may be hollow and the roller may be partially located within the boom. However to avoid a boom of undue diameter the mast end of the hollow portion should then be cutaway to accommodate the wound luff and boltrope of the sail, which is of considerably greater bulk than the rest of the wound sail.
  • the tack (i.e. foot of the luff) of the sail will be attached to attachment means mounted on or adjacent to the universal joint.
  • attachment may be to a short spindle between the mast and the universal joint, so as to attach as close to the line of the mast track as practicable.
  • the tensioning means is preferably a two-part swivel which allows the sail to be wound up without also winding a tensioning cable attached thereto around the roller.
  • the combination of the boom and the tensioning means may be sufficient to interconnect the free ends of the roller and the boom.
  • the roller when the roller is mounted above the boom it is preferred to also provide at the free end of the boom an upwardly extending member having an aperture into which the free end of the roller is slidably and rotatably received.
  • the rotation meahs is a manual handle, pu l ley or motor drive. This will usually be mounted insi d e t h e mast or at the other side to the boom, so as to allow the sail luff to be wound up close to the mast.
  • Fig. 1 shows a reefing or furling boom with the roller inside the boom
  • Fig. 2 shows a reefing or furling boom with the roller outside the boom.
  • Fig. 1 shows yacht mast 14, mainsail 13 and a reefing or furling boom assembly 10.
  • the boom assembly 10 comprises a boom 11 having a rigid shell structure. Within the boom 11 is a rotatable roller 12 to which the sail 13 is attached.
  • the roller 12 is connected to the mast 14 by way of a universal joint 15 and the boom 11 is connected to the mast 14 by a double-acting swivel or a conventional gooseneck fitting 16. This allows the boom to move in the horizontal and vertical planes about the mast.
  • the tensioning means comprises a two part slidable member 18 on the roller 12 and a pulley system 32 attached thereto.
  • the slidable member 18 is attached to the clew 17 of the sail and the pulley system 32.
  • the inner part 18 is keyed to the roller 12 so that as the roller 12 rotates, it will rotate with it so as to wind the sail around the roller; whilst the second or outer part of the member 18 rotates on the roller 12, so that when the roller rotates it will not wind the tensioning cable around the roller.
  • the free end of the roller is connected to the free end of the boom by a swivel 8.
  • the mast end foot (the tack 6) of the sail 13 is attached to a mounting 7 on the mast side of universal joint 15 so as to wind the foot of the sail onto the roller.
  • the sail 13 is fed through a slot (not shown ) in th e s h e ll o f the hollow boom 11. onto the roller 12.
  • the sai l is attac h ed to the mast by the conventional mast trac k and f ed through the fast feeder 19.
  • the roller is rotated by a handle 20 or by other suitable rotating means such as a winch system (not shown) , connected to a fixed pulley wheel 34.
  • Reduction gearing and motorised power sources may be located within the mast 14.
  • the top of the mast end of the shell of the hollow boom- is provided with a cutaway 5 so that the luff of the sail containing the boltrope is wound up outside the hollow boom since the wound luff is too bulky to be contained within the boom section.
  • FIG. 2 shows another embodiment of the invention in which the roller 21 is outside the boom 22.
  • the roller 21 and boom 22 are interconnected at their free ends remote from the mast 23 by means of a bracket 35 upstanding from the free end of the boom, and which has a bush (not shown) into which the free end of the roller is rotatably and slideably received.
  • the tensioning means comprising the two part slidable member 28 and the pulley system 33. is positioned at the ends of the roller 21 and boom 22 which are remote from the mast 23.
  • the roller 21 is connected to the mast 23 by a universal joint 24 and the boom is connected by a conventional gooseneck joint 25.
  • the sail 26 is attached to the mast 23 by conventional track means and fast feeder 27. As in Fig. 1 the roller is rotated by the handle 20 or by other suitable means such as an internal pulley 34 within the mast 23. Again, the boom 22 is capable of performing all its normal functions.
  • FIGs. 1 and 2 are not to scale but have been drawn in a manner so as to illustrate the various features of the invention.

Abstract

Un gui de ferlage ou d'arisage (10) comprend un gui (11) relié au mât (14) par un col de cygne (16), et un rouleau (12) sur lequel une voile (13) peut être enroulée et qui est reliée au mât par un accouplement articulé universel (15). Les extrémités libres du gui et du rouleau sont reliées l'une à l'autre de manière à pivoter ensemble. Le pied (6) de l'extrémité de la voile côté mât est relié à l'accouplement articulé universel de sorte que ladite extrémité peut être enroulée sur le rouleau sans s'écarter sensiblement de la ligne du mât.
