Abstract

A sailing kayak in the form of catamaran with a folding sail is solving the problem of kayak and folding sail structures which enable high paddling speed, small watercraft weight, high stability, and settability/foldability of the sail from the watercraft cockpit during navigation. The sailing kayak is composed of a main hull (1) and a smaller side hull (2) which are connected by a front (3) and a rear crossbar (4). On the front crossbar there is attached a folding tripod mast which serves as a framework for the sail (9). The tripod mast is assembled of three bars, of which only one (6) is fixedly fastened to the front crossbar, while the remaining two (7, 8) are movable and enable setting and folding of the sail. All three bars are linked together on the top by means of a flexible assembly. The setting of the sail is carried out at first by clamping the bar (7) in the point (10) in front of the kayak cockpit and then by positioning the bar (8) in the point (11) by means of a tensioning rope (12).

Description

Predmet izuma je jadralni kajak v obliki katamarana z zložljivim jadrom, ki je namenjen potovanju po mirnih vodah (morje, jezera) s pomočjo veslanja ter s pomočjo jadra.The object of the invention is a sailing kayak in the shape of a catamaran with a collapsible sail, which is intended for sailing through calm waters (sea, lakes) by rowing and using a sail.

Tehnični problem, ki ga rešuje izum, je konstrukcija kajaka in zložljivega jadra, ki združuje naslednje lastnosti: visoka hitrost veslanja, majhna masa, visoka stabilnost plovila in zložljivost jadra. Jadro mora biti enostavno postavljivo/zložljivo med samo plovbo in zloženo ne sme ovirati veslanja, postavitev in zložitev pa mora biti mogoča iz kokpita plovila.A technical problem solved by the invention is the construction of a kayak and a folding sail that combines the following features: high rowing speed, low weight, high vessel stability and sail foldability. The sail must be easily retractable / foldable during the voyage itself and must not be obstructed by rowing, and the positioning and folding must be possible from the cockpit of the vessel.

Znanih rešitev je več vrst in so opisane v naslednjih patentih:There are several known solutions and are described in the following patents:

FR2589815, US3777690, US3902443, US4621587, US4646669, US4751889, US4809629, US4958582, US5289792, US5657713, US6112692, US6240865, US6390013, US6427619, US6457430, US6615758, US6655314, US6807919, US6892660, US6986318, US7165501, VV2003024777US377657, US667800, US670828, US670600, US470800

Navedeni patenti na različne načine rešujejo problem stabilnosti kajaka, uporabo jadra, in problem zložljivosti jadra. Iz pregleda obstoječih patentov, ter tudi iz pregleda ponudbe svetovnih proizvajalcev jadralnih kajakov oz. potovalnih kajakov, opremljenih s pomožnim jadrom, je razvidno, da je opisani tehnični problem še slabo rešen, saj obstoječe rešitve ne zmorejo zadovoljiti vseh navedenih pogojev tehničnega problema: zmožnosti hitrega veslanja, majhne mase, visoke stabilnosti plovila, opremljenosti z jadrom, ter postavljivosti/zložljivosti jadra med plovbo iz kokpita plovila.These patents solve the problem of kayak stability, sail use, and sail foldability in various ways. From the review of existing patents, as well as from the review of the offer of global manufacturers of sailing kayaks and it is evident that the described technical problem is still poorly solved, since the existing solutions cannot satisfy all the stated conditions of the technical problem: ability to speed rowing, low weight, high stability of the vessel, equipment with sail, and of sail folding while sailing from the cockpit of a vessel.

Po izumu je problem rešen s konstrukcijo kajaka oblike katamarana, ki se sestoji iz glavnega trupa in stranskega pomožnega trupa, ter z inovativno konstrukcijo zložljivega jadra s tronogim jamborjem. Katamaranska konstrukcija kajaka omogoča zaradi skupne širine visoko stabilnost plovila, hkrati pa sta zato lahko kajak in stranski trup zelo ozka in s tem izredno hitra. Prednja povezovalna prečka med kajakom in stranskim trupom služi tudi kot pritrdišče jamborja, ki je tako nameščen sredi katamarana med obema trupoma. To plovilu omogoča dobro stabilnost med jadranjem, in sicer v obeh smereh glede na veter (veter z leve ali z desne strani), hkrati pa zloženo jadro v neaktivnem stanju nudi dovolj prostora za neovirano veslanje. Stabilna tronoga konstrukcija jamborja omogoča postavitev jamborja brez dodatnih napenjalnih vrvi, postavitev in zložitev jadra pa je mogoča iz kokpita plovila med samo plovbo.According to the invention, the problem is solved by the construction of a catamaran shaped kayak consisting of a main hull and a lateral auxiliary hull, and an innovative construction of a folding sail with a tripod mast. The catamaran design of the kayak allows for high stability of the vessel due to the overall width, and at the same time the kayak and the side hull can be very narrow and therefore extremely fast. The front connecting bar between the kayak and the side hull also serves as the mast anchorage, which is thus positioned in the middle of the catamaran between the two hulls. This gives the boat good stability while sailing in both wind directions (left or right winds), while at the same time folding sail in idle condition provides ample space for unimpeded rowing. The rigid mast construction of the mast allows the mast to be erected without additional tensioning ropes, and the sail can be installed and folded from the cockpit of the vessel during navigation.

Izum bo opisan na izvedbenem primeru in slikah, ki prikazujejo sl 1: jadralni kajak z dvignjenim jadrom sl 2: jadralni kajak z zloženim jadromThe invention will be described by way of example and illustrations showing FIG. 1: sailing kayak with raised sail. Sl 2: sailing kayak with folded sail.

Jadralni kajak je sestavljen iz glavnega trupa 1, ter manjšega stranskega trupa 2. Trupa sta med seboj povezana s prednjo 3 in zadnjo prečko 4 in tako skupaj tvorita negibljivo enoto. Glavni trup ima na zadnjem delu tudi krmilo v enaki izvedbi, kot je običajno pri tekmovalnih kajakih za mirne vode. Na prednji prečki je na mestu 5 pritrjen zložljivi tronogi jambor, ki služi kot nosilno ogrodje za jadro 9. Tronogi jambor je sestavljen iz treh palic, od teh je le ena 6 fiksno pritrjena na prednjo prečko 3, ostali dve 7 in 8 pa sta gibljivi in omogočata postavljanje in zlaganje jadra. Vse tri palice so spete na vrhu z gibljivim sklopom, ki omogoča premikanje prostih koncev palic v poljubnih smereh. Jadro je s prednjo stranico vpeto na jambor, in sicer na palico 6.The sailing kayak consists of the main hull 1 and the smaller lateral hull 2. The hulls are interconnected with the front 3 and the rear crossbar 4, thus forming a rigid unit together. The main hull also has a rudder in the rear in the same version as is usual with competitive kayaks for calm waters. A folding tripod mast is mounted on the front crossbar in place 5, which serves as a supporting frame for sail 9. The tripod mast consists of three rods, of which only one 6 is fixedly fixed to the front crossbar 3, the other two 7 and 8 are movable and allow the sail to be positioned and stacked. All three rods are clamped at the top with a flexible assembly that allows the free ends of the rods to be moved in any direction. The sail is fixed to the mast from the front, to the pole 6.

Zloženo jadro omogoča neovirano veslanje. V zloženi legi je jadro skupaj s tronogim jamborjem naslonjeno na zadnjo prečko 4 in s tem primerno učvrščeno za nemoteno veslanje. Dodatna učvrstitev zloženega jadra je mogoča s pomočjo napenjalcev jadra, namenjenih jadranju (zaradi boljše preglednosti so na slikah izpuščeni) - s tem je dosežena popolna učvrstitev zloženega jadra, da se ne more gibati levo/desno in ovirati veslanja.The folded sail allows for unhindered rowing. In the folded position, the sail, together with the tripod mast, rests on the rear crossbar 4 and is thus properly fixed for smooth rowing. Additional fixing of the folded sail is possible with the help of sail tensioners intended for sailing (for the sake of clarity, they are omitted in the pictures) - thus achieving a perfect fixing of the folded sail so that it cannot move left / right and obstruct rowing.

Iz faze veslanja je mogoče s postavitvijo jamborja preiti v fazo jadranja. Postavitev jadra iz zložene lege v aktivno lego se izvrši prek naslednjih dveh korakov:From the rowing phase, it is possible to go into the sailing phase by erecting a mast. Positioning the sail from the folded position to the active position is accomplished through the following two steps:

a) najprej se palico 7 vpne na mesto 10 pred kokpit kajaka,a) first, stick pole 7 in position 10 in front of the kayak cockpit,

b) nato se palica 8 s pomočjo napenjalne vrvi 12 potegne na mesto 11, ki se nahaja na stičišču kajaka 1 in prednje prečke 3.b) the rod 8 is then pulled into position 11 by means of a tensioning rope 12 at the junction of the kayak 1 and the front crossbar 3.

S tem je postavitev jamborja (in hkrati tudi jadra) končana, jadro 9 se nahaja v aktivnem položaju in omogoča jadranje. Ker pritrdilno mesto 11 ni dosegljivo iz kokpita 14, je na tem mestu nameščeno napenjalno uho, skozi katerega je napeljana vrv 12. Napenjanje vrvi in pritrditev z napenjalcem 13 je tako mogoča iz kokpita kajaka.This completes the mast (and at the same time sail) layout, sail 9 is in the active position and enables sailing. As the mounting point 11 is not accessible from the cockpit 14, a tensioning ear is installed at this point through which a rope 12 is guided.

Zlaganje jadra poteka na enak način kot postavljanje, le v obratnem vrstnem redu. Najprej je potrebno sprostiti napenjalec 13 in s tem sprostiti pritrjeni konec palice 8 na mestu 11. Po sprostitvi je mogoče celotno konstrukcijo jadra že spustiti na povezovalni prečki 3 in 4. Ko je jadro položeno na prečki, se sprosti še vpetje palice 7 na mestu 10, obe palici 7 in 8 pa se nato primakne k vpeti palici 6. Jadro se zvije okoli vseh treh palic, ter nazadnje učvrsti v zloženi legi, primerni za veslanje. Tudi zlaganje jadra je v celoti mogoče iz kokpita, kar pomeni, da lahko postopek postavljanja in zlaganja jadra izvajamo tudi med plovbo po odprtih vodah, kjer ni možnosti pristanka.Sailing is done in the same way as laying, only in reverse order. It is first necessary to release the tensioner 13 and thereby release the fastened end of the bar 8 at position 11. After release, the whole sail structure can already be lowered on connecting bars 3 and 4. When the boat is laid on the bars, the bar assembly 7 is released again at position 10 , then both rods 7 and 8 then move to the clamped rod 6. The sail rolls around all three rods and finally locks in a folded rowing position. Sailing is also possible entirely from the cockpit, which means that the sailing and stowing procedure can also be performed while sailing in open waters without landing options.
