Description
Sistema per il fissaggio di mura di vele prodiere System for fixing the tack of bow sails
DESCRIZIONE E FINALITÀ DESCRIPTION AND PURPOSE
I natanti a vela anche con più alberi ma in particolare quelli armati a sloop, con un albero, una randa ed un fiocco, sono nella grande maggior parte dei casi equipaggiati con uno strumento, chiamato avvolgifiocco o rollafiocco, utilizzato per avvolgere la vela di prua, fiocco o genoa, attorno allo strallo di prua dove è lo strumento è installato al di sopra della landa. L'avvolgimento della vela prodiera avviene a seguito della rotazione, tramite apposita cima, dell'avvolgifiocco a cui è agganciato tramite apposito golfare o similare l'angolo di mura della vela di prua, cioè l'angolo inferiore prodiero. A causa dell'installazione dell'avvolgifiocco e dell'aggancio dell'angolo di mura della vela quest'ultimo risulta innalzato dal piano di coperta innalzando in tale modo anche il centro di spinta della vela e soprattutto riducendo la portanza della vela stessa a causa del vento che sfugge tra la base rialzata della vela ed il piano di coperta. Per evitare gli inconvenienti sopra detti alcune barche hanno l'avvolgifiocco inserito in un vano all'interno della coperta in modo che la base della vela non risulti rialzata. Sailboats even with more than one mast but in particular those armed with a sloop, with a mast, a mainsail and a jib, are in the vast majority of cases equipped with an instrument, called furling or rollafiocco, used to furl the headsail , jib or genoa, around the forestay where the instrument is installed above the land. The furling of the forward sail takes place following the rotation, by means of a special rope, of the furling to which it is attached by means of a special eyebolt or similar to the tack angle of the headsail, that is the lower forward angle. Due to the installation of the furling and the hooking of the tack angle of the sail, the latter is raised from the deck level thus also raising the center of thrust of the sail and above all reducing the lift of the sail itself due to the wind that escapes between the raised base of the sail and the deck. To avoid the aforementioned inconveniences, some boats have the jib furler inserted in a compartment inside the deck so that the base of the sail is not raised.
L'obiettivo che la presente invenzione vuole conseguire consiste in una semplice ed immediata soluzione a basso costo al problema tecnico posto per tutte le tipologie di natanti con vela prodiera e avvolgifiocco. The objective that the present invention intends to achieve consists in a simple and immediate low-cost solution to the technical problem posed for all types of boats with forward sail and furling jib.
Lo stato dell'arte attuale non rileva non alcun dispositivo che consenta una soluzione al problema posto o che induca al trovato di seguito descritto. Il trovato proposto consiste nell'inserire l'angolo di mura della vela prodiera in un altro golfare o similare di prora su un dispositivo da installare in modo solido, sia fisso che amovibile, immediatamente a ridosso del piano di coperta sulla parte inferiore dell'avvolgifiocco o sullo strallo prodiero o anche sulla landa di ancoraggio dello strallo prodiero stesso. Il trovato deve comunque presentare una dimensione longitudinale che sia almeno sufficiente a superare l'avvolgifiocco per evitare l'ostacolo per la vela rappresentato dallo stesso avvolgifiocco. The current state of the art does not reveal any device which allows a solution to the problem posed or which leads to the invention described below. The proposed invention consists in inserting the tack angle of the forward sail in another eyebolt or similar in the bow on a device to be installed in a solid way, both fixed and removable, immediately behind the deck on the lower part of the furling either on the forestay or even on the anchorage of the forestay itself. The invention must in any case have a longitudinal dimension which is at least sufficient to overcome the furling to avoid the obstacle for the sail represented by the furling itself.
Il golfare o equivalente può anche essere ancorato direttamente sulla coperta tramite fori e fissato con bulloni e dadi o saldature. The eyebolt or equivalent can also be anchored directly to the deck through holes and fixed with bolts and nuts or welds.
Infatti, dopo aver fissato l'angolo di mura all'avvolgifiocco tramite il golfare o similare ed una volta aperta la vela e bloccato l'avvolgifiocco lascando la scotta e la drizza della vela si sgancia l'attacco dell'angolo di mura dal golfare dell'avvolgifiocco e facendo scorrere nella inferitura verso la coperta la vela si aggancia l'angolo di mura della medesima vela nell'altro golfare inferiore ben fissato e si cazzano di nuovo drizza e scotta. In fact, after having fixed the tack angle to the furling through the eyebolt or similar and once the sail has been opened and the furler locked, leaving the sheet and the halyard of the sail, the attack of the tack angle is released from the eyebolt of the furling jib and by sliding the sail into the luff towards the deck, the tack angle of the same sail is hooked into the other well-fixed lower eyebolt and halyard and sheet are pulled again.
Per evitare le manovre sopra dette è possibile installare sulla vela sotto la mura agganciata all'avvolgifiocco una seconda mura a distanza opportuna per l'aggancio al trovato o al golfare fissato direttamente sulla coperta. To avoid the aforementioned maneuvers, a second tack can be installed on the sail under the tack attached to the furling jib at a suitable distance for hooking to the found or to the eyebolt fixed directly on the deck.
La figura mostra l'avvogifiocco 1 sullo strallo 11 di prua ancorato tramite il fissaggio 8 alla landa 3 della prua 2, che presenta un golfare 5 con un moschettone 4 per l'aggancio della mura 14 della vela 16 e riporta sotto l'avvogifiocco 1 il dispositivo 7 di solido fissaggio del golfare 9 o di un similare in cui è inserito il moschettone 6 o equivalente per l'aggancio della mura 15 della vela 16. Il dispositivo 7 è costituito da un golfare 9 di un possibile sistema a tenaglia o equivalente con perno 10 di rotazione dei bracci 12 intorno allo strallo 11 con avvitamento del bullone 14 mediante la manovella 13. The figure shows the furling jib 1 on the forestay 11 anchored by means of the fastening 8 to the plate 3 of the bow 2, which has an eyebolt 5 with a carabiner 4 for hooking the tack 14 of the sail 16 and brings the furling 1 underneath. the device 7 for solidly fixing the eyebolt 9 or similar in which the carabiner 6 or equivalent is inserted for hooking the tack 15 of the sail 16. The device 7 consists of an eyebolt 9 of a possible pincer system or equivalent with pivot 10 for rotation of the arms 12 around the forestay 11 with screwing of the bolt 14 by means of the crank 13.
Il dispositivo 7 può essere diverso e fissato sulla landa 3 ed il golfare 9 può anche essere direttamente fissato con bulloni o anche saldato permanentemente sulla landa o imbullonato o saldato direttamente sulla coperta. The device 7 can be different and fixed on the plate 3 and the eyebolt 9 can also be directly fixed with bolts or even welded permanently on the plate or bolted or welded directly on the deck.
