Abstract

The invention relates to a device for a ship (2) which exhibits a pivotally mounted door element (3) so arranged as to function as a door in an upward-pivoted covering position in an opening (4) in the ship (2), and as a ramp in a downward-pivoted position affording passage. A movably supported further ramp component (8) is so arranged as to be capable of displacement between a raised stowed position close to the upper part of the opening and essentially horizontal and perpendicular in relation to the door element (3) and an extended ramp position to permit loading and unloading respectively. The externally situated ramp component (8) is movably supported separated from the door element (3). The invention offers considerable protection against the door (3) suffering damage as a consequence of the ramp being forced inwards against the ship (2), for example in the event of damage to the bow visor/bow doors or in the event of a collision, in that the door (3) has been separated from the ramp (8), and yet it still permits them to interact with one another to form a common vehicular access ramp (10) when necessary.

Description

Fig 6 visar en ovanvy av arrangemanget sàsom det visas i Fig 5. Fig. 6 shows a top view of the arrangement as shown in Fig. 5.

En anordning 1 vid ett fartyg 2, som uppvisar ett svängbart lagrat portelement 3 vilket är anordnat att fungera som en port i uppsvängt förtäckningsläge F vid en öppning 4 hos fartyget 2, och som en ramp för bl.a. körning av fordon därpå när det befinner sig i nedsvängt passerläge P, är t.ex. av i och för sig känt slag, och kan vara anordnat att manövreras medelst linor 5 som löper över block 6 och är paverk- bar att svängas ut medelst en känd utstötare 7. Vidare är en ytterligare anordnad rampdel 8 rörligt lagrad att vara förbar mellan ett stuvningsläge S och ett utsträckt rampläge F för att i sagda utsträckta rampläge R förbinda fartygets inre lastnings- utrymme 9 med fartygets utsida och därvid tillàta lastning respektive lossning av fartyget 2 via sagda bildade ramp 10.A device 1 at a ship 2, which has a pivotally mounted port element 3 which is arranged to function as a port in the upturned cover position F at an opening 4 of the ship 2, and as a ramp for e.g. driving a vehicle thereon when it is in the lowered access position P, is e.g. of a kind known per se, and may be arranged to be maneuvered by means of ropes 5 which run over block 6 and are susceptible to being swung out by means of a known ejector 7. Furthermore, a further arranged ramp part 8 is movably mounted to be movable between a stowage position S and an extended ramp position F for connecting the said internal loading space 9 of the ship to the outside of the ship in said extended ramp position R and thereby allowing loading and unloading of the ship 2 via said formed ramp 10.

Enligt föreliggande uppfinning är den yttre belägna rampdelen 8, sett i riktning fràn fartygets inre lastut- rymme 9 lagrad rörlig skilt fran portelementet 3. I utsträckt läge R kan denna rampdel 8 samverka med portelementet 3 till att fungera som en gemensam ramp 10 eller fungera skilt fràn var- andra, så att den sagda rampdelen 8 endast aktiveras när långa avstånd A mellan fartyg 2 och land etc exempelvis en kaj 11 öns- kas överbryggas, t.ex. vid en öppningsbar för 2A hos en färja.According to the present invention, the outer located ramp part 8, seen in the direction of the ship's internal cargo space 9, is mounted movably separate from the port element 3. In extended position R this ramp part 8 can cooperate with the port element 3 to function as a common ramp 10 or function separately from each other, so that the said ramp part 8 is only activated when long distances A between ship 2 and land, etc., for example a quay 11 is desired to be bridged, e.g. at an opening bar for 2A of a ferry.

I fortsättningen beskrives endast utförandet när portelementet 3 och den sagda ytterrampdelen 8 fungerar tillsam- mans som en gemensam enhet, vilket visas pà ritningarna.In the following, the embodiment is only described when the door element 3 and the said outer ramp part 8 function together as a common unit, as shown in the drawings.

Den sagda ytterrampdelen 8 är förbunden med stöd 11 som är anordnat att vid stuvning av sagda del 8, företrädes- vis mottagen tätt intill öppningens övre del 4A utmed ett däck 12, fungera som uppbärningsstöd för densamma.The said outer ramp part 8 is connected to a support 11 which is arranged to act as a supporting support for the same when the said part 8, preferably received close to the upper part 4A of the opening along a tire 12, is stored.

Ytterrampdelen 8 är svängbart förbunden med en till fartyget 2 i sin tur ledat förbunden svängdel 13 som före- trädesvis bildas av parvisa på inbördes avstånd X från varandra sidledes förskjutna svängarmar 14, 15 som är förbundna med var- andra vid armarnas respektive fria ändar 14A, 15A. Sagda för- bindning som sträcker sig mellan svängarmarna 14, 15 bildas av en bom 16 eller någon liknande skivformig del som är anordnad , att vid nedsvängt läge N utav svängarmarna 14, 15 och ytterramp- delen 16, samt portelementet 3 kunna fungera som en mellan portelementets yttre fria änddel 3A och ytterrampdelens in mot fartyget 2 vända änddel 8A överbryggande mellanrampdel 16.The outer ramp part 8 is pivotally connected to a pivot part 13 connected in turn to the vessel 2, which is preferably formed by pairs of mutually spaced apart pivot arms 14, 15 which are connected to each other at the respective free ends 14A of the arms. 15A. Said connection extending between the pivot arms 14, 15 is formed by a boom 16 or some similar disc-shaped part which is arranged, that in the pivoted-down position N of the pivot arms 14, 15 and the outer ramp part 16, and the gate element 3 can function as an intermediate the outer free end portion 3A of the door element and the bridging intermediate ramp portion 16A facing the end 2 facing the vessel 2.

Svängarmarna 14,.15 är lagrade via svängaxlar 17 på ungefär gemensam nivå 18 med nivån 20 för portelementets svänglagring 21 och förskjutna i riktning 22 ut från svänglag- ringarna 21, så att när portelementet 3 hålles i tillslutet läge n _ och ytterrampdelen 8 befinner sig i stuvningsläget S är port- elementet 3 och svängarmarna 14, 15 uppsvängda, väsentligen i vertikalt läge parallella med varandra, se Fig 1.The pivot arms 14, 15 are mounted via pivot shafts 17 at approximately common level 18 with the level 20 of the pivot bearing 21 of the door element and displaced in direction 22 out of the pivot bearings 21, so that when the door element 3 is kept in closed position n - and the outer ramp part 8 is in the stowage position S, the door element 3 and the pivot arms 14, 15 are swung up, substantially in vertical position parallel to each other, see Fig. 1.

Ytterrampdelen 8 uppvisar vid dess in mot farty- get 2 vända ände 8A två stela sidledes förskjutna lagringsbärar- mar 23 vid vars yttre ändar 23A en svängled 24 ansluter till var sin vid svängdelens 13 ut från fartyget 2 vända sida l3B belägna lagringsfästen 25.The outer ramp part 8 has at its end 8A facing the vessel 2 two rigid laterally displaced storage carriers 23 at the outer ends 23A of which a pivot joint 24 connects to each of the mounting brackets 25 located at the side of the pivot part 13 facing out of the vessel 2.

Förutom som stödfunktion är sagda som uppbär- ningsstöd fungerande parvisa armar 11 även anordnade att vid respektive sida 4A, 4B av portöppningen fungera som ett sväng- armsarrangemang 26 tillsammans med lagringsbärarmarna 14, 15 och därigenom åstadkomma önskat svängningsmönster 27, 28 för ytter- rampdelen 8, samtidigt som portelementet 3 svänges mellan till- slutet läge F respektive öppnat läge P, liknande s.k. parallell- stag.In addition to being a support function, said paired arms 11 acting as support supports are also arranged to function at respective sides 4A, 4B of the door opening as a pivot arm arrangement 26 together with the storage support arms 14, 15 and thereby achieve the desired pivot pattern 27, 28 for the outer ramp part 8. , at the same time as the door element 3 is pivoted between closed position F and open position P, similar to so-called parallel stays.

Svänglagringen 29 för det respektive uppbär- ningsstödet 11 är anordnat på lägre nivå 30 än vad svängarmarnas och portelementets svänglagringar 17, 21 är belägna på.The pivot bearing 29 for the respective support support 11 is arranged at a lower level 30 than the pivot bearings 17, 21 of the pivot arms and the gate element are located.

Sagda svängarmsarrangemang är anordnat så att svängarmarna 14, 15 och ytterrampdelen 8 är hållna i väsentligen vinkelrätt läge så som visas i Fig 1, med ytterrampdelen 8 före- trädesvis mottagen tätt intill öppningens övre del 4C.Said pivot arm arrangement is arranged so that the pivot arms 14, 15 and the outer ramp part 8 are held in a substantially perpendicular position as shown in Fig. 1, with the outer ramp part 8 preferably received close to the upper part 4C of the opening.

Längst ut på ytterrampdelen 8 finnes en sväng- bart ledad kilformad nivàreglerflap 31 med vars hjälp jämn anslutning mellan t.ex. kaj 11 och ytterrampdelen 8 kan åstad- kommas.At the far end of the outer ramp part 8 there is a pivotally articulated wedge-shaped level control flap 31 by means of which an even connection between e.g. quay 11 and the outer ramp part 8 can be provided.

Uppfinningen medför stor säkerhet mot att porten 3 skall skadas på grund av att rampen tryckes in mot fartyget 2, 507 496 4 t.ex. vid skada utav bogvisir eller vid kollision genom att man separerar porten 3 från rampen 8, men andà möjliggör att de kan samverka med varandra till bildande av en gemensam korramp 10, se Pig 5. Även ytterrampdelen 8 är lämpligen anordnad att drivas av en lina 32.The invention provides great security against the port 3 being damaged due to the ramp being pressed against the vessel 2, 507 496 4 e.g. in the event of damage from an arch visor or in the event of a collision by separating the door 3 from the ramp 8, but still enabling them to cooperate with each other to form a common corridor 10, see Pig 5. .

Uppfinningen ar ej begränsad till det ovan beskrivna och på ritningarna visade utforingsexemplet, utan kan varieras inom ramen för patentkraven utan att uppfinningstanken fràngàs.The invention is not limited to the exemplary embodiment described above and shown in the drawings, but can be varied within the scope of the claims without departing from the spirit of the invention.
