Definitions

  • the present invention relates to a new type of sail support device.
  • the present invention aims to overcome these drawbacks by presenting a new type of sail support device making it possible to fold and unfold the sail very quickly without manual intervention, to act on the orientation of the sail without maneuvering. and to vary the sail area at will.
  • the new sail support device is characterized in that it consists of a vertical mast that rotates by means of its longitudinal axis, of several arms articulated on either side on the said vertical mast and arranged in the same plane, automatic actuation means of the arms around their articulation on the vertical mast and automatic drive means in rotation of the vertical mast with respect to its longitudinal axis.
  • the new type of sail support device consists of a vertical mast 1 rotating relative to its longitudinal axis, several arms 7 articulated on said vertical mast and arranged in the same plane vertical, automatic actuation means of the arms 7 around their articulation on the mast 1 and automatic drive means in rotation of the mast 1 vertical relative to its longitudinal axis.
  • the vertical mast 1 consists of a vertical cylindrical tube 3 fixed to the boat by any known means and of a second cylindrical tube 4 threaded onto the fixed tube 3.
  • the second tube 4 is mounted to rotate freely on the tube 3 fixed on the boat and is locked in translation in the lower part by a stop 5.
  • a circular hollow plate 6 for guying On the upper part of the fixed tube 3 is mounted a circular hollow plate 6 for guying.
  • the arms 7 on each side of the mast are connected to each other by their end by a flexible link 8.
  • the ends of the arms 7 on each side of the mast 1 can be linked by a rigid bar.
  • actuating means consist of two cables 9 and 10 each fixed to the end of the upper arms 7.
  • the folding is preferably done downwards but can be provided to be performed upwards.
  • the electric brake motor includes a clutch which allows the folding of the sail instantaneously by gravity, In order to absorb the difference in development and keep the cables 9, 10, 13 and 14 in tension, a tension spring 15 whose extension is limited by a strap 16 is interposed in the circuit of cables 9 and 10.
  • a toothed wheel 17 intended to be driven in rotation by an endless screw 18 mounted on the axis of an electric brake motor 19 fixed on the boat at the foot of the mast 1 thus controlling the orientation of the sail support.
  • the sail fabric is securely fixed along the flexible links 8 and on the two lower arms 7.
  • a notch 20 facilitates the folding of the fabric.
  • This veil fabric advantageously passes through a space 21 arranged along the pivoting tube 4.
  • Said space is enlarged at the base to allow the gathers of the sail to be accommodated during folding.
  • the fabric thus held and not fixed, can slip under the effect of folding and unfolding.
  • a protective cover 22 is stretched around said sail and its support by cables 23 and 24 passing through pulleys fixed on the guying plate 6.
  • the mast 1 is constituted by telescopic elements.
  • the device compoete an Inateur 26 driving a catch 27 passing through pulleys 28 and cummandant the development of the telescopic elements 25.
  • the arms 7 are articulated on the upper end of each telescopic element 25.
  • the articulation of the arms 7 is preferably arranged on supports so that said articulations are aligned on the same vertical on each of the sides of the mast.
  • the mast 1 is provided with a rotary base 29 blocked in translation by a fixed base 30 and cooperating with an electric brake motor or an irreversible worm gear motor.
  • the present invention allows very fast folding and unfolding of the sail, an orientation of the sail controlled without maneuvering, and is of simple design and adaptable to any type of nautical craft.
