Description

Anordning ved redningsbåter, joller eller lignende fartøyer av metall eller kunststoff. Device for lifeboats, dinghies or similar vessels made of metal or plastic.

Oppfinnelsen vedrører en anordning The invention relates to a device

ved redningsbåter, joller eller lignende far-tøy med luftkasser som er dannet av tverrskott, hvor tverrskottene strekker seg inntil høyden av de ellers vanlige tverrtofter og danner en forbindelse mellom ytterhuden, kjøl og båtripen. in the case of lifeboats, dinghies or similar vessels with air boxes that are formed by transverse bulkheads, where the transverse bulkheads extend up to the height of the otherwise usual transverse bulkheads and form a connection between the outer skin, keel and the hull.

Der kjennes redningsbåter av tverr-spanttypen med løst innbyggede luftkasser som er tilpasset båtens form, og som for å oppnå den nødvendige fasthet har et stort antall tverrspanter, stringere, bunnplater etc. There are lifeboats of the cross-frame type with loosely built-in air boxes that are adapted to the shape of the boat, and which, in order to achieve the necessary firmness, have a large number of cross-frames, stringers, bottom plates etc.

Videre kjennes redningsbåter med Rescue boats are also known

langskipsspanter og med en eller flere på hver båtside anordnet, som luftkasser ut-formede hulromseksjoner som overlapper hverandre, idet båtens ytterhud samtidig tjener som luftkassevegg og fasthetsdrager. longship frames and with one or more cavity sections arranged on each side of the boat, designed as air boxes, which overlap each other, as the boat's outer skin simultaneously serves as an air box wall and support girders.

Med tverrspantbyggemåten er det imidlertid bare mulig å fremstille redningsbåter eller lignende fartøyer som enten har den nødvendige stivhet i lengderetningen, men da neppe den tilstrekkelig lille egenvekt. Ved byggemåten med langskipsspanter oppnås riktignok en lav egenvekt, men stiv-heten i lengderetningen er mangelfull, da f. eks. den hulromseksjon som strekker seg i båtens lengderetning ikke har den nød-vendige fasthet i tverretningen. Ved stor belastning vil der ved bevegelse utad av båtsidene opptre tverrsnittsforandringer som igjen tvangsmessig fører til forminsk-else av hovedspantets motstandsmoment. Dessuten krever egenarten av denne byggemåte med langskipsspanter mange plass-røvende dyre kassemodeller og innretnin-ger og vanskeliggjør på grunn av ugunstige hjørneforbindelser en kontinuerlig arbeids-gang. However, with the cross-frame construction method, it is only possible to produce lifeboats or similar vessels that either have the necessary stiffness in the longitudinal direction, but hardly the sufficiently low specific weight. The construction method with longship frames does indeed achieve a low specific weight, but the stiffness in the longitudinal direction is deficient, as e.g. the cavity section that extends in the longitudinal direction of the boat does not have the necessary firmness in the transverse direction. In the event of a large load, when the boat sides move outwards, cross-sectional changes will occur, which in turn inevitably lead to a reduction in the main frame's moment of resistance. In addition, the unique nature of this construction method with long-ship frames requires many space-consuming, expensive box models and fittings and, due to unfavorable corner connections, makes continuous work difficult.

Videre kjennes redningsbåter med et stort antall dobbeltsidig trinnformig utfor-mede sittebenker som strekker seg på tvers gjennom båten, og som er festet på det ytterste skrog av båten og består av luft-tette kammere. Disse kammere er enten gjennomgående fra en båtside til en annen eller delt ved hjelp av en tverrvegg. Med denne trinnformige anordning av setene er det mulig å anbringe et størst mulig antall personer i båten, samtidig som båten får den nødvendige fasthet i tverretningen. Furthermore, lifeboats are known to have a large number of double-sided step-shaped benches which extend across the boat, and which are attached to the outermost hull of the boat and consist of air-tight chambers. These chambers are either continuous from one side of the boat to another or divided by means of a transverse wall. With this staggered arrangement of the seats, it is possible to place the largest possible number of people in the boat, while at the same time giving the boat the necessary firmness in the transverse direction.

Ved denne byggemåte er den ulempe tilstede at for det første ytterhuden har en liten bulefasthet og således har en tilbøye-lighet til å bh lekk. For det annet er ved denne byggemåte driften praktisk talt bare mulig ved hjelp av motor. Dessuten går ved lekkasje i ett eller flere av de store luft-kammere et forholdsvis stort luftvolum som oppdriftsmiddel tapt. Oppfinnelsen går ut på å oppheve disse ulemper og består i at hver luftkasse er oppdelt ved hjelp av to langsgående skott samt at de midtre luftkasser er gitt en opphøyet bunn, og at der i flukt med de langsgående skott og mellom de av tverrskottene dannede luftkasser er anordnet langsgående dragere på hvilke propellhånddriftens stangsystem er montert, hvilket system strekker seg under den forhøyede bunn for de nevnte midtre luftkasser. With this method of construction, the disadvantage is that, firstly, the outer skin has little bulge resistance and thus has a tendency to leak. Secondly, with this construction method, operation is practically only possible with the help of a motor. In addition, if there is a leak in one or more of the large air chambers, a relatively large volume of air is lost as a buoyancy agent. The invention aims to eliminate these disadvantages and consists in that each air box is divided by means of two longitudinal bulkheads and that the middle air boxes are given a raised bottom, and that flush with the longitudinal bulkheads and between the air boxes formed by the transverse bulkheads are provided with longitudinal girders on which the propeller hand drive rod system is mounted, which system extends below the raised bottom of said central air boxes.

Et eksempel på oppfinnelsens utførelse An example of the embodiment of the invention

er vist på tegningen hvor: is shown in the drawing where:

Fig. 1 er et tverrsnitt efter linjen A — B i fig. 3. Fig. 2 er et lengdesnitt av rednings-båten i midtskipsplanet, og Fig. 3 et grunnriss av samme. Fig. 1 is a cross-section along the line A — B in fig. 3. Fig. 2 is a longitudinal section of the lifeboat in the midships plane, and Fig. 3 a floor plan of the same.

Med kjølen 1, båtripen 2 og ytterhuden 3 er tverrskottene 4 — 11 fast forbundet. With the keel 1, the keel 2 and the outer skin 3, the transverse bulkheads 4 — 11 are firmly connected.

Disse tverrskott utfyller omtrent det hele tverrsnitt av bunnen. Mellom tverrskottene 4 og 5, 6 og 7, 8 og 9, 10 og 11 er det på babord og styrbord side anordnet langsgående skott 12. Ved denne anordning dannes henholdsvis tre luftkasser 13, som er lufttett lukket ved hjelp av et deksel 14. These transverse bulkheads complete approximately the entire cross-section of the bottom. Between the transverse bulkheads 4 and 5, 6 and 7, 8 and 9, 10 and 11, longitudinal bulkheads 12 are arranged on the port and starboard sides. This arrangement forms three air boxes 13 respectively, which are sealed airtight by means of a cover 14.

Dekselet 14 er fast forbundet med ytterhuden 3, tverrskottene 4 — 11 og de langsgående skott 12 til en enhet. Luftkas-sene 13 er så brede at de i båtens tverr-retning danner sittebenker i to rekker for den rygg mot rygg sittende besetning. Den midtre av de således dannede tre luftkasser 13> oppdeles lufttett med en ekstra bunn 15. The cover 14 is firmly connected to the outer skin 3, the transverse bulkheads 4 — 11 and the longitudinal bulkheads 12 into one unit. The air boxes 13 are so wide that in the transverse direction of the boat they form benches in two rows for the crew sitting back to back. The middle of the three air boxes 13> formed in this way is divided airtight with an additional bottom 15.

Under den ekstra bunn 15 kan der nå innarbeides vilkårlige gjennombrudd 16 i tverrskottene 4 — 11, hvilke gjennombrudd anvendes som gjennomgangsåpninger for vann og drivstenger. Under the additional bottom 15, arbitrary openings 16 can now be incorporated in the transverse bulkheads 4 — 11, which openings are used as passage openings for water and drive rods.

For ytterligere å øke langskipsfasthe-ten er det mellom tverrskottene 5 og 6, 7 og 8, 9 og 10 anordnet dragere 17, som er fast forbundet med ytterhuden 3 og tverrskottene. Dragernes 17 forbindelse med tverrskottene foregår hensiktsmessig på de steder ved hvilke også langsgipsskottene 12 er forbundet med tverrskottene. Fra tverrskottet 4 og tverrskottet 11 strekker dra-gerne 17 for propelldrivanordningens stangsystem seg henholdsvis til baugen og ak-terenden. De innebyggede dragere 17 blir ved hjelp av en dekkplate 18 forbundet løs-bart med hverandre, så at de i forbindelsen med ytterhuden 3, dekkplaten 18, tverrskottene 4 — 11, langskipsskottene 12 og bunnen 15 danner en kassedrager som strekker seg nesten over hele båtens lengde. To further increase the longship's strength, girders 17 are arranged between the transverse bulkheads 5 and 6, 7 and 8, 9 and 10, which are firmly connected to the outer skin 3 and the transverse bulkheads. The connection of the girders 17 to the transverse bulkheads takes place suitably at the places where the longitudinal plaster bulkheads 12 are also connected to the transverse bulkheads. From the transverse bulkhead 4 and the transverse bulkhead 11, the beams 17 for the propeller drive device's rod system extend respectively to the bow and stern end. The built-in girders 17 are releasably connected to each other by means of a cover plate 18, so that in connection with the outer skin 3, the cover plate 18, the transverse bulkheads 4 - 11, the longship bulkheads 12 and the bottom 15 they form a box girder which extends almost over the entire length of the boat length.

Ved denne beskrevne anordning til-veiebringes en overordentlig høy avstiv- With this described device, an extremely high stiffening

ning av ytterhuden, og i forbindelse med denne, kjølen og båtripen en ytterst stabil og fast forbindelse i båtens lengde- og tverr-retning, hvilken forbindelse gjør seg meget gunstig gjeldende særlig ved redningsbåter av lettmetall eller kunststoff. ning of the outer skin, and in connection with this, the keel and the keel, an extremely stable and firm connection in the boat's longitudinal and transverse direction, which connection is very beneficial especially for lifeboats made of light metal or plastic.

Utførelsen av båten i henhold til oppfinnelsen er mulig i sveise- og naglekonstruksjon, samt i en kombinasjon av disse to konstruksjoner. Særlige fordeler opp-nåes imidlertid når båten som følge av tekniske vanskeligheter bare kan bygges i naglekonstruksjon. Nagleforbindelsene er således anordnet at de er godt tilgjengelige på ethvert sted og sikrer en hurtig og god klinking. I forbindelse med den mulighet at den foreslåt-te båt kan fremstilles seksjonsvis, gir de nevnte egenskaper forutsetningen for en gunstig industriell fremstilling. The construction of the boat according to the invention is possible in welded and riveted construction, as well as in a combination of these two constructions. Particular advantages are achieved, however, when the boat can only be built in riveted construction due to technical difficulties. The rivet connections are arranged in such a way that they are easily accessible in any place and ensure fast and good riveting. In connection with the possibility that the proposed boat can be produced section by section, the aforementioned properties provide the prerequisite for a favorable industrial production.
