Description

1 2572051

  The present invention relates to a new type of support device

sail port.

  Maneuvering a traditional sail is difficult automatically

  sand. Commonly, it is done using winches and mittens that require for their actuation and monitoring a human presence.

  In addition, such maneuvers are very tedious for

  and are often quite long, which is a disadvantage

case of imminent danger.

  The present invention aims to obviate these disadvantages by presenting

  as a new type of sail support device to obtain the folding and unfolding of the sail very quickly without manual intervention, to act on the orientation of the sail without

  maneuver and vary the sail area at will.

  For this purpose, the new sail support device is

  in that it consists of a vertical mast rotating relative to its longitudinal axis, several articulated arms port and other on the said vertical mast and arranged in the same plane,

  automatic actuating means for the arms around their

  vertical mast training and automatic training

  rotation of the vertical mast with respect to its longitudinal axis

nal.

  Other advantages and features will appear in the

  description of the device according to the invention represented by the drawings

  appended by way of non-limiting example and in which: - Figure 1 is a front view of the unfolded sail support device according to a first embodiment, - Figure 2 is a front view of the device according to the invention in folded position, - Figure 4 is a side view of the device in the folded position, - Figure 5 is a front view of the device in the unfolded position.

  according to a second embodiment.

  As represented in FIGS. 1 and 5, the new type of sail support device consists of a vertical mast 1 rotatable relative to its longitudinal axis, with several arms 7 articulated on the said vertical mast and arranged in the same vertical plane. , from

  means for automatically actuating the arms 7 around their orthosis

  lation on mat 1 and automatic means of

  rotation of the mast 1 vertical with respect to its longitudinal axis.

  According to a first embodiment of the device according to the invention,

  vention, the vertical mast 1 consists of a vertical cylindrical tube 3 fixed to the boat by any known means and a second

  4 cylindrical tube threaded on the fixed tube 3.

  The second tube 4 is mounted free to rotate on the tube 3 fixed on the boat and is locked in translation in the lower part by a

stop 5.

  On the upper part of the fixed tube 3 is mounted a hollow tray

circular 6 of guying.

  On the pivoting tube 4 are articulated on both sides to 180 arms 7 whose number varies according to the need for resistance to the

sailing force.

  The arms 7 on each side of the mast are interconnected by their

end by a flexible link 8.

  According to another embodiment (not shown) the

  mites arms 7 on each side of the mast 1 can be connected

by a rigid bar.

  The movement of these arms 7 around their articulation on the mat

  1 is controlled by automatic actuating means.

  These actuating means are constituted by two cables 9 and 10

  each attached to the end of the upper arms 7.

  These cables 9 and 10 pass through two independent pulleys 11 dis-

  placed at the head of the pivoting tube 4 and will wind together in one direction on the drum of an electric brake motor 12 fixed on the

said pivoting tube.

  The rotation of the drum thus controls the folding and unfolding of

arm 7.

  ! 0 The folding is preferentially down but can be

  planned to be performed upwards.

  On the other hand, two other cables 13 and 14 each fixed at the end

  the lower arms 7 wind together in the other direction! 5 on the drum of the electric brake motor 12 thus maintaining the

system in return voltage.

  Advantageously, the electric brake motor comprises a clutch

  which allows the folding of the sail immediately by gravity.

  In order to absorb the difference in development and to keep in

  cables 9, 10, 13 and 14, a tension spring 15 of which

  the extension is limited by a strap 16 is inserted in the cir-

cooks cables 9 and 10.

  Preferably, on the base of the pivoting tube 4 is fixed a toothed wheel 17 intended to be rotated 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

sailing support.

  According to a preferred embodiment, the sail fabric is fixed firmly along the flexible links 8 and on both arms

lower 7.

  An indentation 20 facilitates the folding of the fabric.

  This sail fabric advantageously passes to a space 21 arranged on

along the swivel tube 4.

  The said space is enlarged at the base to allow the housing of

  gathers of the sail during folding.

  The fabric thus maintained and not fixed, can slide under the effect of

folding and unfolding.

  Advantageously, when the sail is folded, a protective cover

  22 is stretched around the said sail and its support by cables 23 and 24 passing through pulleys fixed on the plateau

guying 6.

  According to a second embodiment of the spupport device

  for sail, the mast 1 is constituted by telescopic elements

  c. According to this embodiment h, the device comprises an engine

  26 dragging a cable 27 passing through pulleys 28 and commanding

  the development of the telescopic elements 25.

  The arms 7 are hinged to the upper end of each telescopic member. The articulation of the arms 7 is preferably arranged on supports so that said articulations are aligned on a

  even vertical on each side of the mat.

  In the lower part, the mat 1 is provided with a rotary base 29 locked in translation by a fixed base 30 and cooperating with an electric brake motor or an irreversible gear reducer motor.

unending.

  This type of telescopic mast, when folded, gives a very small footprint, the sail support device can

  be used on trawlers where the place is very limited.

  The present invention allows a very fast folding and unfolding of the sail, an orientation of the sail controlled without maneuvering, and is

  simple and adaptable to any type of watercraft

ticks.

  It goes without saying that the present invention can accommodate all

  all variants in the field of technical equivalents

  without departing from the scope of this patent.
