Abstract

This invention is an assembly on a ship (1), which by means of at least one mobile deck component (6), which is movable between an upper "storage position", where the component (6) in one deck area (2) is held in position against a fixed deck (3), and a lower "working position", where the component (6) is held in position at a desired distance from said fixed deck (3), allows the deck area (2) to be divided into a number of deck areas (4<A>, 4<B>, 4<C>, etc).Among other things, the invention allows the automatic locking and unlocking of the deck component (6).Said auxiliary deck component (6) has a number of locking devices (14), which are arranged to work together with each one's contact surface (21), which runs along the movement track of said components (6), and which in one area where the component (6) is desired to assume its "working position" along one part (22) retracts away from the component (6). When the component moves down towards the "working position", locking devices (14) attach to the corresponding surface (21) and are driven in to said retracting part (22), in which a stop (24) is positioned that works together with said locking device (14) to fasten the component (6) in "working position." When the component (6) is moved up towards the "storage position" the lock device (14) works together with the corresponding retracting part (22) and is driven out from the retracting part (22) towards the component (6) and thereby disengages the locking function.<IMAGE>

En på ritningarna i fig. 4 visad RORO-farkost, som betecknas med siffran 1, uppvisar anordningar enligt före- liggande uppfinning som möjliggör att däcksutrymmen 2, vars höjd begränsas av fasta däck 31, 32, 33, 34 o.s.v., enkelt kan indelas i ett flertal mindre delutrymmen 4A, 48, 4c o.s.v., till vilka ramper 5 leder för att möjliggöra att lasta respektive lossa exempelvis fordon, som transporteras medelst farkosten. Önskat lastningsutrymme kan på känt sätt erhållas medelst ett antal hjälpdäckselement 6, som är rörliga utmed respektive utrymmes väggar 7 till önskad nivå och låsbara i sagda läge.A RORO vehicle shown in the drawings in Fig. 4, denoted by the number 1, has devices according to the present invention which enable deck spaces 2, the height of which is limited by fixed decks 31, 32, 33, 34, etc., to be easily divided into a plurality of smaller subspaces 4A, 48, 4c, etc., to which ramps 5 lead to make it possible to load and unload, for example, vehicles which are transported by means of the vehicle. The desired loading space can be obtained in a known manner by means of a number of auxiliary deck elements 6, which are movable along the walls 7 of the respective space to the desired level and can be locked in said position.

Respektive element 6 uppvisar lämpligen fyrkantig företrädesvis kvadratisk omkretsform och ett flertal element 6 kan anordnas att bilda ett gemensamt till önskad nivå förflyttbart extradäck, såsom framgår av bl.a. figurerna 12-14.Respective elements 6 suitably have a square, preferably square circumferential shape, and a plurality of elements 6 can be arranged to form a common extra tire which can be moved to the desired level, as can be seen from e.g. Figures 12-14.

Utmed väggarna 7 och övriga begränsningar, såsom förstyvningsbalkar 8 och liknande, är anordnade styrorgan 9 som vn 446 711 är avsedda att styra respektive,element 6 vid dess förflytt- ning utmed väggarna 7 etc. En styrorgandel 9A är förbunden med exempelvis ena änden av en balk 10, som ingár i stommen till elementet 6, och en ytterligare stynorgandel 9B är förbunden med exempelvis en vägg 7 eller en upprättstående förstyvningsbalk 8.Along the walls 7 and other limitations, such as stiffening beams 8 and the like, guide means 9 are arranged which are intended to guide the respective parts 66 in their movement along the walls 7, etc. A guide member part 9A is connected to, for example, one end of a beam 10, which is included in the body of the element 6, and a further groove member 9B is connected to, for example, a wall 7 or an upright stiffening beam 8.

Förflyttning av sagda element 6 till önskad nivå ástadkommes medelst vajrar 11 eller andra lämpliga dragorgan, som med dess ena ände 11A är förbundna med element 6, exempelvis såsom visas i fig. 10, och som är omlänkade kring brythjul 12 och sträcker sig till en drivanordning 13, som lämpligen kan vara anordnad att manövreras från ett antal paneler vid respektive däcksyt- rumme 2.Movement of said element 6 to the desired level is effected by means of wires 11 or other suitable pulling means, which with its one end 11A are connected to element 6, for example as shown in Fig. 10, and which are linked around breakers 12 and extend to a drive device. 13, which may suitably be arranged to be operated from a number of panels at the respective deck surface space 2.

Fastlåsning av sagda element 6 i önskat övre upphissat läge intill ett fast däck 3, dess s.k. "lagringsläge', åstadkommas lämpligen medelst sagda drivanordning 13, medan ett antal låsorgan 14 av exempelvis det slag, som visas detaljerat i fig. 2, brukas för att läsa elementet 6 i dess nedsänkta s.k. "bruksläge", vid vilket läge elementet 6 fungerar som ett extra däck.Locking of said element 6 in the desired upper raised position next to a fixed deck 3, its so-called "storage position", is suitably provided by said drive device 13, while a number of locking means 14 of, for example, the type shown in detail in Fig. 2, are used to read the element 6 in its submerged so-called "operating position", in which position the element 6 functions as an extra tire.

Làsorganet 14 är lämpligen tappformigt och upp- bäres förskjutbart av en lagringshylsa 15, som är stelt förbun- den med elementet 6 i omrâdet av dess omkretsområde. Ett elas- tiskt eftergivligt element 16, som lämpligen utgöres av en skruvtryckfjäder 16, är anordnat vid elementet 6. Den ena änden 16A av elementet 16 är mottagen av en lämpligen skâlformig mot- trycksdel 17, som är anordnad att stelt förbindas med däcks- elementet 6, exempelvis med en balk 18 via en skruvanordning 19.The locking means 14 is suitably pin-shaped and is slidably supported by a storage sleeve 15, which is rigidly connected to the element 6 in the area of its circumferential area. An elastically resilient element 16, which is suitably constituted by a helical compression spring 16, is arranged at the element 6. One end 16A of the element 16 is received by a suitably shell-shaped counter-pressure part 17, which is arranged to be rigidly connected to the tire element 6, for example with a beam 18 via a screw device 19.

Fjäderns andra ände 163 är i sin tur mottagen av en ytterligare lämpligen skálformig mottrycksdel 20, som lämpligen är mottagen av sagda första mottrycksdel 17, och lämpligen är ledbart förbunden med làsorganet 14. Genom fgaderns tryckkraft pâverkas lásorganet 14 att tvàngsvis föras i elementets radiella rikt- ning. Det är även möjligt att låta ett fjäderorgan 16 samverka med ett flertal làsorgan 14 eller att låta ett flertal fjäder- organ 16 samverka med ett enda låsorgan 14, vilket ökar säker- heten för sagda làsorgans funktion.The second end 163 of the spring is in turn received by a further suitably cup-shaped counterpressure part 20, which is suitably received by said first counterpressure part 17, and is suitably articulated connected to the locking means 14. By the compressive force of the spring the locking means 14 is forced into the radial direction ning. It is also possible to allow a spring means 16 to co-operate with a plurality of locking means 14 or to allow a plurality of spring means 16 to co-operate with a single locking means 14, which increases the safety of said locking means function.

Utmed sagda däckselements rörelsebana sträcker sig utmed tillhörande vägg 7 etc. en anliggningsyta 21, som kan vara spårformig. Nederpartiet av sagda anliggningsyta 21 upp- 446 711_ visar ett i riktning från ett däckselement 6 fjärmande parti 22.Along the path of movement of said tire elements, an abutment surface 21 extends along the associated wall 7, etc., which may be groove-shaped. The lower part of said abutment surface 21 shows a portion 22 extending in the direction from a deck element 6.

Sagda fjârmande anliggningsparti 22 lutar snett nedåt och formar en ficka 23 i väggen 7 anpassad att kunna mottaga ena änden 14A av låsorganet 14. Vid området av nedre delen av sagda parti 22 och fickan 23 uppbäres ett stopp 24, som bildas av ett bärele- ment avsett att kunna samverka med låsorganets undre parti 148.Said resilient abutment portion 22 slopes obliquely downwards and forms a pocket 23 in the wall 7 adapted to receive one end 14A of the locking means 14. At the area of the lower part of said portion 22 and the pocket 23 a stop 24 is supported, which is formed by a support element intended to be able to cooperate with the lower part of the locking member 148.

En urtagning 25 bildas därvid mellan stoppelementet 24 och det fjärmande partiet 22, vilken urtagning är avsedd att mottaga och samverka med en nedåtriktad låsklack 26, som är förbunden med låsorganet 14.A recess 25 is then formed between the stop element 24 and the removing portion 22, which recess is intended to receive and cooperate with a downwardly directed locking lug 26, which is connected to the locking member 14.

Funktionen av anordningen är såsom nedan angives: Efter påverkan av drivanordningen 13 nedsänkes ett hjälpdäcks- element 6, som kan uppbära ett låsorgan 14 åtminstone i elemen- tets respektive hörnomrâden, från dess intill ett fast däck 3 belägna "lagringsläge" medelst linorna 11 under samtidig styr- ning via styrorganen 9. Låsorganets yttre frontyta 14C anligger ständigt mot den utmed exempelvis en vägg 7 sig sträckande an- liggningsytan 21, och när sagda frontyta l4C når kontakt med det fjärmande partiet 22 av sagda yta 21 påverkas låsorganet 14 genom inverkan av fjädern 16 att mottagas av fickan 23 och ut- skjutas till kontakt med partiet 22. Elementet 6 nedsänkes till dess "bruksläge", vid vilket lásorganets undre parti 148 anlig- ger mot stoppet 24, som uppbär elementet 6 i sagda läge och förhindrar dess ytterligare nedsänkning. Lâsklacken 26, som därvid mottages i urtagningen 25, förhindrar att låsorganet 14 oavsiktligt indrages och overksamgör dess lásförmåga.The function of the device is as follows: After actuation of the drive device 13, an auxiliary deck element 6, which can support a locking member 14 at least in the respective corner areas of the element, is immersed from its "storage position" adjacent to a fixed deck 3 by the ropes 11 during simultaneous control via the guide means 9. The outer front surface 14C of the locking means abuts constantly against the abutment surface 21 extending along, for example, a wall 7, and when said front surface 14C reaches contact with the removing portion 22 of said surface 21, the locking means 14 is actuated by the spring 16 to be received by the pocket 23 and extended to contact the portion 22. The element 6 is lowered to its "position of use", at which the lower portion 148 of the locking member abuts against the stop 24, which carries the element 6 in said position and prevents its further immersion. . The locking lug 26, which is then received in the recess 25, prevents the locking member 14 from being inadvertently retracted and deactivates its locking ability.

Ett indikeringsorgan kan därvid vara anordnat vid respektive låsorgan 14 och exempelvis genom färgmarkeringar in- dikera lásorganets läge, exempelvis från elementets undersida.An indicating means can then be arranged at the respective locking means 14 and, for example by color markings, indicate the position of the locking means, for instance from the underside of the element.

Ytterligare element 6, som medföljer ovan sagda elements nedsänkning vid omrâdet av dess undersida, kan på lik- nande ovan sagda sätt fortsätta att nedsänkas till dess respek- tive önskade 'bruksläge”.Additional element 6, which accompanies the immersion of the above-mentioned element at the area of its underside, can in a similar manner as stated above continue to be immersed to its respective desired 'operating position'.

När drivanordningen 13 påverkas att upphissa elementet 6 kommer låsorganet 14 automatiskt att intryckas i riktning mot elementet 6 genom samverkan mellan det lutande partiet 22 och làsorganfrontytan 14C och därigenom upphäva låsförmâgan samt möjliggöra, att elementen 6 upphissas till dess respektive 'lagringsläge'. 5 446 711 Uppfinningen är ej begränsad till de ovan be- skrivna utföringsexemplen, utan kan varieras till sina detaljer inom ramen för efterföljande patentkrav.When the drive device 13 is actuated to raise the element 6, the locking means 14 will automatically be pressed in the direction of the element 6 by cooperation between the inclined portion 22 and the locking means front surface 14C and thereby cancel the locking ability and enable the elements 6 to be raised to their respective 'storage position'. The invention is not limited to the embodiments described above, but can be varied in its details within the scope of the appended claims.
