Descrizione dell'invenzione dal titolo: Description of the invention entitled:
"DISPOSITIVO PER LA PRATICA DELLO SCI D'ACQUA" "DEVICE FOR THE PRACTICE OF WATER SKIING"
La presente invenzione ha per oggetto un dispositivo propulsore per la pratica dello sci d'acqua. The present invention relates to a propulsion device for practicing water skiing.
Non vi ? dubbio che lo sci d'acqua, a differenza del tradizionale sci sulla neve, rappresenti una attivit? sportiva sensibilmente costosa, e quindi di carattere alquanto elitario. Ci? ? dovuto alla necessit? di disporre di un natante addetto al traino dello sciatore. In molti casi, ? necessario il coinvolgimento di una terza persona, che affianca il pilota del mezzo trainante per il necessario coordinamento tra quest'ultimo e lo sciatore. Not there? doubt that water skiing, unlike traditional snow skiing, represents an activity? sensibly expensive sports car, and therefore of a somewhat elitist character. There? ? due to the need? to have a boat used to tow the skier. In many cases, ? It is necessary to involve a third person, who supports the driver of the towing vehicle for the necessary coordination between the latter and the skier.
Scopo dell'invenzione, ? quello di eliminare la necessit? del mezzo di traino, per cui lo sciatore acquatico pu? dedicarsi a questo sport in maniera del tutto autonoma, con costi contenuti, ed in condizioni di assoluta sicurezza per s? e per i terzi. Purpose of the invention,? to eliminate the need? of the towing vehicle, so the water skier can? devote yourself to this sport in a completely autonomous way, with low costs, and in conditions of absolute safety for s? and for third parties.
Secondo l'invenzione, si . prevede un dispositivo propulsore comprendente,in combinazione, un galleggiante profilato in cui ? installato un motore primo, ad elica o ad idrogetto, ed un'asta rigida di spinta, solidale col detto corpo galleggiante, munita dei comandi per il motore, e provvista di un manicotto elastico trasversale, che si appoggia posteriormente al corpo dello sciatore per provocarne la spinta. According to the invention, yes. provides a propelling device comprising, in combination, a profiled float in which? installed a prime mover, propeller or hydrojet, and a rigid thrust rod, integral with said floating body, equipped with the controls for the motor, and provided with a transversal elastic sleeve, which rests on the back of the skier's body to cause the push.
Sempre secondo l'invenzione, l'estremo anteriore della detta asta di spinta oltre ai comandi relativi al motore, reca anche un interruttore di emergenza, situato anch'esso in corrispondenza della impugnatura, destinato a provocare l'automatico spegnimento del motore, quando la detta impugnatura viene abbandonata per cause incidentali. Always according to the invention, the front end of said push rod, in addition to the controls relating to the engine, also carries an emergency switch, also located in correspondence with the handle, intended to cause the automatic shutdown of the engine, when the said grip is abandoned for accidental reasons.
L'invenzione verr? ora descritta con riferimento ai disegni allegati, che rappresentano a titolo illustrativo e non gi? limitativo un preferita forma di esecuzione dell'invenzione stessa. Will the invention come? now described with reference to the attached drawings, which represent by way of illustration and not already? limiting a preferred embodiment of the invention itself.

Con riferimento alle figure da 1 a 3, la lettera L sta ad indicare la linea di galleggiamento ed il numero 10 indica una coppia di galleggianti profilati paralleli, del tipo "catamarano" collegati dalla piattaforma 11 sulla quale ? sistemato un motore 12 di tipo commerciale, di adeguata potenza, protetto dalla cofanatura asportabile 13. Nel piano di simmetria dei galleggianti 10 ? situato l'albero di trasmissione 14 recante l'elica 15, adeguatamente protetta dalla griglia di.sicurezza 16 portata dalla incastellatura immersa 17. With reference to figures 1 to 3, the letter L indicates the waterline and the number 10 indicates a pair of parallel profiled floats, of the "catamaran" type connected by the platform 11 on which? fitted a commercial type motor 12, of adequate power, protected by the removable hood 13. In the plane of symmetry of the floats 10? the transmission shaft 14 carrying the propeller 15 is located, adequately protected by the safety grid 16 carried by the immersed frame 17.
Nella parte anteriore della piattaforma 11 ? ancorata la barra di spinta 18, provvista del giunto di ripiegamento 19, e terminante all'estremo libero con l'impugnatura a manopola 20 che comanda l'acceleratore. Un interruttore di emergenza a strappo 21 ? disposto presso la manopola 20, allo scopo di arrestare automaticamente il motore quando la manopola 20 viena abbandonata per qualsiasi causa. Presso l'estremo anteriore della barra di spinta 18 ? sistemato un galleggiante 27 avente lo scopo di mantenere la barra 18 in condizioni di galleggiamento. At the front of the platform 11? anchored the push bar 18, provided with the folding joint 19, and ending at the free end with the knob handle 20 which controls the accelerator. An emergency pull switch 21? arranged near the knob 20, in order to automatically stop the engine when the knob 20 is abandoned for any reason. At the front end of the push bar 18? arranged a float 27 having the purpose of keeping the bar 18 in floating conditions.
Come si vede nelle figure 2 e 3, la barra rigida 18 reca un tratto trasversale, su cui ? applicato un manicotto elastico 22. As can be seen in Figures 2 and 3, the rigid bar 18 bears a transverse section, on which? applied an elastic sleeve 22.
La figura 4 illustra l?impiego del dispositivo secondo l'invenzione: lo sciatore impugna la manopola 20, ed ? spinto dal manicotto elastico 22 che agisce contro il suo corpo. Di preferenza, l'interruttore di emergenza, come gi? accennato, ? del tipo a strappo, per cui se per un qualsiasi motivo, intenzionale o accidentale, lo sciatore abbandona la manopola 20, il motore si arresta istantaneamente. Figure 4 illustrates the use of the device according to the invention: the skier holds the knob 20, and? pushed by the elastic sleeve 22 which acts against its body. Preferably, the emergency switch, as already? mentioned,? of the tear-off type, whereby if for any reason, intentional or accidental, the skier abandons the knob 20, the engine stops instantaneously.
In figura 5, nella quale uguali numeri di riferimento stanno ad indicare parti gi? descritte, la barra 18 reca due appendici anteriori simmetriche 23 sagomate a manubrio, ed i manicotti elastici di spinta 22 cooperano con un poggia-schiena 24 portato sul supporto 25 in posizione regolabile tramite il morsetto 26. In Figure 5, in which the same reference numerals indicate parts already? described, the bar 18 has two symmetrical front appendages 23 shaped like a handlebar, and the elastic thrust sleeves 22 cooperate with a backrest 24 carried on the support 25 in an adjustable position by means of the clamp 26.
Come gi? detto, il motore del propulsore pu? essere sia del tipo ad elica, sia del tipo idrogetto . How already? said, the engine of the propeller can? be both of the propeller type and of the water jet type.
In figura 6 ? illustrata la possibilit? di installare, al posto del manicotto di spinta precedentemente descritto, un galleggiante 28 sagomato a sediolo, che consente di praticare lo sci d'acqua sia in piedi, alla maniera usuale, sia seduti, come mostrato in figura 7. In figure 6? illustrated the possibility? to install, in place of the thrust sleeve previously described, a seat-shaped float 28, which allows water-skiing to be practiced both standing up, in the usual way, and sitting, as shown in figure 7.
La presente invenzione ? stata illustrata e descritta in una sua preferita forma di esecuzione, ma si intende che varianti costruttive potranno esservi in pratica apportate da un esperto del ramo, senza peraltro uscire dall'ambito di protezione della presente privativa industriale. The present invention? has been illustrated and described in a preferred embodiment thereof, but it is understood that constructional variations may be made in practice by an expert in the art, without however departing from the scope of protection of the present industrial patent.
