CLASS INTERNATIONAL SWEDISH B 63d65 c: 13 PATENT AND REGISTRATION AGENCY Ans. 9468/1961 was received on 22/91961 issued on 25/11 1963 G VAN DER PUTTEN, TROSA Device for propelling a boat by hand Priority requested from 24 September 1960 (Norway) The present invention relates to a propulsion device for boats and closer to the horse. a propulsion device for Lk-tare boats, such as the type used on beaches when surfing, by hand.
Manga typer av roddbatar, vilka framdrivas med tillhjälp av dror genom handkraft, aro vanligen kanda. I regel dr roddaren i dessa batar placerad med ryggen mot fardriktningen, vilket ej är lampligt med tanke pa upplaggningen av batens kurs, medan dessutom man8vreringen saint handhavandet av arorna är en konst vilken fordrar att man f5rst beharskar den. Detta galler i okad grad for den roddstil, som ibland anvandes av trana.de rod-dare och vid vilken roddaren vanligen driver fram baten ailed aroma medan han star upp ,och är vand mot fardriktningen. Dessutom anvandes endast en del av roddrorelserna for framdrivning. Many types of rowing boats, which are propelled with the help of drones by hand, are usually known. As a rule, the rower in these boats is placed with his back to the direction of travel, which is not appropriate in view of the layout of the boat's course, while in addition the maneuvering and handling of the oars is an art which requires that you first master it. This applies to an increasing degree to the rowing style which is sometimes used by trana.de rowers and in which the rower usually pushes the boat ailed aroma while standing up, and is water against the direction of travel. In addition, only part of the rowing movements were used for propulsion.
Syftet med uppfinningen dr forenkling av r5relserna, namligen upp- och nedrorelsen av aroma, vilken ej fordrar flagon trailing, och anyandningen av denim enkla rorelse i bada riktningarna for framdrivning av baten. The object of the invention is to simplify the movements, namely the up and down movement of aroma, which does not require flag trailing, and the use of denim simple movement in both directions for propulsion of the boat.
For att uppna detta syfte astadkommes enligt uppfinningen en anordning for framdrivning av en bat med handkraft, besta.ende av havarrnar vilka aro v.ridbart lagrade pa batens kanter och innefattande ett handtag eller liknande vid inneranden och en vinge eller blad vid ytteranden, kannetecknad av att havstangerna svanga runt horisontella axlar parallella med Wens langdriktning och att vane vinge an vridbar i en begransad utstraekfling runt sin langdaxel mellan tvâ lagen belagna p vardera sidan av det plan som roper genom vridningsaxeln och rorelseriktningen. To achieve this object, according to the invention there is provided a device for propelling a boat by hand, consisting of the oats which are rotatably mounted on the edges of the boat and comprising a handle or the like at the inner end and a wing or blade at the outer end, characterized by that the sea rods pivot about horizontal axes parallel to Wen's longitudinal direction and that the habit of the wing rotatable in a limited extension around its longitudinal axis between two layers coated on each side of the plane shouting through the axis of rotation and the direction of movement.
Framdrivningsanordningar for batar med ett blad som kan forflyttas i vattnet aro redan kanda i och Ufa.' sig, i sin enklaste form som en lOs vrickara vilken manovreras frail akterspegeln pa en pram i vilket fall konsten att vricka emellertid fordrar stor styrka, skicklighet och framfOr alit lang tra.ning. Propulsion devices for boats with a blade that can be moved in the water are already known in and Ufa. ' itself, in its simplest form as a lOs vrickara which is maneuvered frail the transom on a barge in which case the art of wiggling, however, requires great strength, skill and above all long training.
Mera komplicerade anordningar i vilka mekaniska drivanordningar fOrflytta bladen i vattnet med tillhjalp av stanger, vevaidar osv. aro kanda, men vilka beroende pa sin komplicerade karaktar och sin tyngd ha visat sig vara outforbara och dessutom ej aro lampliga att anvandas f8r ifragavarande a,n.damal. More complicated devices in which mechanical drive devices move the blades in the water with the aid of rods, cranks, etc. are known, but which, depending on their complicated character and weight, have proved to be unfeasible and, moreover, not suitable to be used for the a, n.damal in question.
Bladet k.an vara fast vid havarmens ytter.ande pa olika satt, .t. ex. vasentligen i bladets axel, varvid storre delen ay framdrivningskraften utiivas av bladets spets. The blade can be attached to the outer edge of the sea arm in different ways, .t. ex. essentially in the axis of the blade, the greater part of the propulsion force being exerted by the tip of the blade.
Med hansyn till framdrivningen dr det emellertid larnpligt att Ora infastaingen med hjalp av en axel vilken sedd i riirelseriktningen ligger framfor bladets axel eftersom pd detta satt en storre del av bladet anvandes. With regard to the propulsion, however, it is obligatory to Ora the fastening with the aid of a shaft which, seen in the direction of movement, lies in front of the shaft of the blade, since on this sat a larger part of the blade was used.
FOr anvandningen har raest avsetts mindre lattare batar, t. ex. av den typ vilken visas pa ritningen Framdrivningsanordningen enligt uppfinningen am sa fast pa baten, att den latt kan framforas av en person. For the use, smaller lighter batteries have been intended, e.g. of the type shown in the drawing The propulsion device according to the invention is so fixed to the boat that it can be easily driven by a person.

Fig. 6 shows a force diagram and the two layers which the blade absorbs in the water. In the figures, the corresponding details have the same designation numbers.
Batens skrov betecknas med 1 och ham i stort sett formen av en. surfingbat sadan som anvandes i soderhavet (South Sea surf-boat). Pa batens dack 2 am ett stod eller en utriggare 2-- — 3 stadigt fast, vilken har en lagring for en vridbar axel 4 vid sin snett utombords belagna ande. The hull of the bat is denoted by 1 and he is largely the shape of one. surfing boat as used in the South Sea (South Sea surf-boat). On the deck of the boat 2 am a stand or an outrigger 2-- - 3 firmly fixed, which has a bearing for a rotatable shaft 4 at its obliquely outboard coated spirit.
Till axeln 4 ar, enligt gungbradeprincipen, ett tvaarmat havstangssystem 5 fast av vilket den del som är beld.gen ovanfor batens clack tjanar som handtag, medan pa den del vilken är riktad mot vattnet ett blad 6 ãr monterat pa s5.dant sat, att det kan vrida sig i be-gransad utsteackning runt sin langdaxel. Genom att utova en kraft pa handtaget i vertikal riktning kan bladet 6 films upp och ned i vattnet genom havstangssystemet. To the shaft 4 is, according to the swinging principle, a two-armed sea rod system 5 fixed, of which the part which is beld.gen above the boat's clack serves as a handle, while on the part which is directed towards the water a blade 6 is mounted in such a way that it can rotate in a limited extension around its longitudinal axis. By exerting a force on the handle in the vertical direction, the blade 6 can be filmed up and down in the water through the sea rod system.
Bladet 6 är forsett med en fastaxel 7 vilken är monterad i eller pa bladets framsida...Konstruktionen av styrbords (hoger) blad, visat i fig. 1, 2 och 4, är sadan att axeln. 7 halles i en urborrning vid dude pa havstangen 5 och halles pa plats av en fastbult 8 i ett spar 9 pa stangen, varvid nauanda spar samtidigt begransar bladets vridrorelse. The blade 6 is provided with a fixed shaft 7 which is mounted in or on the front of the blade ... The construction of starboard (right) blades, shown in Figs. 1, 2 and 4, is such that the shaft. 7 is held in a bore at the dude on the sea rod 5 and held in place by a fixed bolt 8 in a groove 9 on the rod, whereby narrow grooves simultaneously limit the rotational movement of the blade.
Konstruktionen av babords (vanster) blad, vilket visas i fig. 1, 2 och 5 ãr sadan att axeln -7 liar ãr forenad med en bronsplatta 11 innesluten i plastbladet, varvid bronsplattan är fast vid haystingssystemet 5 med hjalp av lasbultar 12, och varvid gummibussningar 13 aro anordnade mellan och hopfogade med flansforsedda andbeslag 4. I detta fall är darfor bladet, beroende pa den kraft vilken utovas och som en foljd darav pa sammantryckningen av gummibussningarna 13, monterat pa ha.vstangssystemet pa sadant salt, att det kan vrida sig I en. begrdnsad utstraekning. The construction of port (left) blades, as shown in Figs. 1, 2 and 5, is such that the shaft -7 is joined to a bronze plate 11 enclosed in the plastic blade, the bronze plate being fixed to the hoisting system 5 by means of welding bolts 12, and wherein rubber bushings 13 are arranged between and joined by flanged duct fittings 4. In this case, therefore, the blade, depending on the force exerted and as a consequence on the compression of the rubber bushings 13, is mounted on the sea rod system on such a salt that it can rotate In a. limited extent.
Verkningssattet hos framdrivningsanordningen enligt uppfinningen är foljande: Vid utgangslaget är bladets yta ungefar parallell med rorelseriktningen och d5 handtagen faras uppat kommer den ande pa havstangen vilken är riktad mot vattnet att fOrflytta sig I riktning nedat mot batens skrov. The mode of action of the propulsion device according to the invention is as follows: At the starting point the surface of the blade is approximately parallel to the direction of movement and when the handles are moved upwards, the spirit on the sea rod which is directed towards the water will move downwards towards the hull.
Den del av bladet (baktill) vilken. är mest avlagsen fran infastningen (7, 11) är salunda utsatt for en kraft A (fig. 6). Beroende pa motstandet mot vattnet kommer bladet att intaga ett lage med en vinkel, sasom visas i fig. 6 med heldragna linjer. Under nedatriirelsen genom vattnet kommer en. framdrivande vektor B vilken driver baten framat att uppsta genom bladet. The part of the blade (at the back) which. is most distant from the attachment (7, 11) is thus exposed to a force A (Fig. 6). Depending on the resistance to the water, the blade will assume a bearing at an angle, as shown in Fig. 6 in solid lines. During the descent through the water comes one. propelling vector B which drives the boat forward to arise through the blade.
Med motsatt rOrelse dvs. da handtagen fbras nedat konuner vingen att forflytta sig uppat och intaga ett lage med en vinkel, sasom visas i fig. 6 med streckprickade linjer. Aterigen beroende p0. denna rOrelse kommer den framdrivande vektorn. B, vilken driver baten framat att uppsta. With the opposite rOrelse ie. when the handles are moved downwards, the wing is forced to move upwards and assume a position with an angle, as shown in Fig. 6 with dashed lines. Again dependent p0. this motion comes the propelling vector. B, which drives the boat forward to rise.
Processen, i vilken arorna intaga ett lage med en given vinkel, sker helt automatiskt, i konstruktionen enligt fig. 4 beroende pa fastbultens 8 begransning i sparet 9, medan vid konstruktionen enligt fig. 5 en del foregaende justering är mojlig genom en Mdragning eller ett lossande av lasbultarna 12 och juste ringen av vinkeln dessutom beror pa stork-ken av den. kraft som utovas, i vilket fall den stora fordelen uppnas att bladet intager det mest gynnsamma laget for maximal framdrivning. The process in which the grooves assume a bearing at a given angle takes place completely automatically, in the construction according to Fig. 4 depending on the limitation of the fixed bolt 8 in the groove 9, while in the construction according to Fig. 5 some previous adjustment is possible by a Tightening or a loosening of the welding bolts 12 and the adjustment of the angle also depend on the strength of it. force exerted, in which case the great advantage is obtained that the blade occupies the most favorable layer for maximum propulsion.
Vid start, vid rodd mot vinden eller om en liten segelbat skall bogseras erfordras en. storre framdrivningskraft och detta uppnas automatiskt, eftersom man i detta fall maste utova kraftigare slag beroende pa vilka motstandet pa bladen i vattnet Okar varvid bladen som en foljd darav (i fraga om fig. 5) justera sig sjalva till en storre vinkel vilket resulterar i att en stOrre framdrivningskraft aterigen uppna.s. Vid hogre hastigheter erfordras endast en mindre vinkel vilket automatiskt uppnas genom det minskade vertikaltrycket. When starting, when rowing against the wind or if a small sailboat is to be towed, one is required. greater propulsion force and this is achieved automatically, since in this case one has to exert more powerful blows depending on which the resistance of the blades in the water increases, the blades as a result (in the case of Fig. 5) adjusting themselves to a larger angle which results in a greater propulsion force is again achieved. At higher speeds only a smaller angle is required which is automatically achieved by the reduced vertical pressure.
Styrningen av baten astadkommes genom att ge kraftigare eller langre slag med den ena handen an. med den andra eller genom att kranga mot styrbord eller mot babord. The control of the bat is achieved by giving stronger or longer strokes with one hand. with the other or by tilting towards starboard or towards port.
Det Or naturligtvis mOjligt om sa Onskas, att anordna havstangerna for en harisontell rorelse tram- och tillbaka i vilket fall roddaren kan sitta ned. It is of course possible, said Onskas, to arrange the sea rods for a horizontal movement tram- and back in which case the rower can sit down.
Skrovet och bladen aro gjorda av konstharts arinerad med glasfiber, sa att maximal styrka kombineras med minimal vikt. Stoden och havstangssystemet aro av latt rorkonstruktion. The hull and blades are made of synthetic resin lined with fiberglass, so that maximum strength is combined with minimal weight. The pillar and the sea rod system are of light rudder construction.
En bat av denna typ vilken är i stand att bara ungefar tva vuxna manniskor Or sardeles lamplig ej blott for utovande av sport, utan Oven som livh0.t f8r kustvakter, vilken mojliggor att de kunna hd.m.ta badgaster vilka kommit ut pa for djupt vatten, eller som en bogserbat fOr bogsering av sma segelbatar fran och till en bathamn, 1. ex. Om det Or dO.hg Fordelarna med b5_ten, anordningen och metoden Oro i korthet fOljande: mycket latt konstruktion, enkelt handhavande, att det Or mojligt att sta vand i rdrelseriktningen, att baten framdrives med bladens rOrelse i bada riktningarna och att roddaren medan han star upp Or i stand att utova stor kraft med sina arm- saval som benmuskler, att vagsvallen ge litet motstand och att det Or m011igt beroende naturligtvis pa den kraft som utovas att uppnE hoga farter av upp till ungefar 10 knop. A boat of this type which is capable of accommodating only about two adults. deep water, or as a tugboat for towing small sailboats from and to a bathing harbor, 1. ex. About the Or dO.hg The advantages of the boat, the device and the method Concerns in brief The following: very light construction, easy operation, that it Or possible to stand water in the direction of movement, that the boat is propelled by the movement of the blades in both directions and that the rower while standing It is able to exert great force with its armpits as leg muscles, that the road wall gives little resistance and that it is of course dependent on the force exerted to achieve high speeds of up to about 10 knots.
