DESCRIPTION:
BRIEF SUMMARY
The invention relates to the technical sector of sailing boat riggings.
In general, on sailing boats, the main sail or the sails such as the foresails, are hoisted taut along their foot by a boom. The sail is orientated in function of the orientation of the wind by operating the boom angularly by means of a sheet which is belayed, firstly, on the said boom and secondly, on the sliding slide. This slide is mounted so as to slide on a component known as a deck horse transversally fixed along the centre line of the boat.
This deck horse can be fixed either directly onto the deck or on a support mounted underneath the boom. Therefore, it seems that the clew of the sail situated substantially at the free end of the boom, is arranged substantially above the deck. In all cases, a boom is required in order to hoist taut the foot of the sail and orientate it. However, the disadvantages involved when using a boom are known. In fact, besides the fact that the boom may turn out to be dangerous during certain operations, it takes up considerable room on the deck and limits the position of the tacks.
The invention is aimed at overcoming these disadvantages in a simple, safe and efficient manner.
In order to overcome the problem brought up of being able to eliminate the boom, whilst aiming at clearing the deck a maximum, the device is outstanding in that it comprises a support transversally arranged along the centre line of the boat and designed with means likely to belay the sheet at the rear of the clew of the sail and above the deck of the boat by eliminating the boom and capable of movement of the said sheet in function of the orientation of the sail.
In order to overcome another problem of being able to adjust the belly and twist of the sail, the track is mounted on the support capable of height adjustment. In one embodiment, the track can be mounted on part of the support designed to be adjustable in height.
In order to overcome another problem of being able to offset the sheet slide from one side to the other and outside the freeboard of the boat, the track is made out of two parts one of which is mounted so as to be fixed onto part of the support whereas the other is mounted capable of guided sliding and movement with respect to the said first part, the slide being mounted on the mobile part of the track.
In an advantageous manner, the support is made up of a bow. According to another feature, the top cross member of the bow is fitted with a transversal coiler taking a rain awning.
The invention is described below in more detail accompanied by the following attached drawings in which:
FIGS. 1 and 2 are purely schematic views showing two possibilities for hoisting taut a sail according to the device of the invention.
FIG. 3 is a partial, perspective view of the device.
FIGS. 4, 5 and 6 are perspective views showing different embodiments of the support designed to provide height adjustment of the sheet track.
FIGS. 7 and 8 are perspective views illustrating other means for the height adjustment of the sheet pulling point.
FIG. 9 is a perspective view of another embodiment of the device.
FIG. 10 is a partial plan view of a boat fitted with the device according to FIG. 9.
FIGS. 11 and 12 are perspective views of other alternative forms of embodiment.
The object of the invention will become more apparent from the following non-limitating description when referring to the embodiments in the figures of the drawings.
The device according to the invention is designed to belay the sheet (E) at the rear of the clew (E1) of the sail (V) and above the deck of the boat (P). With this in mind, the device comprises at least one support (1) transversally arranged along the centre line of the boat and at the rear of the clew (E1).
The support (1) is likely to provide the heightwise mounting, above the deck, of a track (2) taking, in a free sliding and position adjustable manner, a slide (3) designed to belay the sheet at the rear of the clew. The sheet track (2) may be rectilinear or bent. In a preferred manner, the support is mad
