En kärra 1 avsedd att användas vid föreliggande transportsystem utgöres av två i riktning snett bakåt och utåt från en till ett fordon 2 anordnad draganordning 3 gående balkar 4. Nämnda balkar 4 är inbördes förbundna endast vid kärrans 1 främre parti så att kärran 1 får en öppen V-form, d.v.s. med två av sagda balkar bildade sidoskänklar 4. Vid vardera skänkeln i huvudsak på dess yttre parti av kärrans l bakre del är anordnade hjul 5. På utsidan av vart och ett av de bakre partierna av nämnda i V-form anordnade skänklar 4 är anordnad en framåtskjutande balk 6, som baktill är förbunden med ifrågavarande skänkel 4 vid dess bakre parti. Därvid bildas en uppbärningsyta 7 på kärran 1 vid dess bakre del och kärrans hjul 5 är därvid belägna mellan nämnda skänkel 4 och balk 6 framför nämnda uppbärningsyta 7. Sagda yta 7 är belägen på en nivå intill eller under hjulens 5 periferi.A cart 1 intended for use in the present transport system consists of two beams 4 going in the direction obliquely backwards and outwards from a towing device 3 arranged. A said beam 4 is interconnected only at the front part of the cart 1 so that the cart 1 has an open V-shape, i.e. with two side legs formed by said beams 4. At each leg substantially on its outer part of the rear part of the cart 1 are arranged wheels 5. On the outside of each of the rear portions of said legs arranged in a V-shape 4 is arranged a projecting beam 6, which is connected at the rear to the leg 4 in question at its rear portion. A support surface 7 is formed on the cart 1 at its rear part and the wheels 5 of the cart are located between said leg 4 and beam 6 in front of said support surface 7. Said surface 7 is located at a level adjacent to or below the periphery of the wheels 5.

En lastkomponent 8 kan, såsom visas på fig. 1-4, ha formen av en låda med öppning upptill. Nämnda lastkomponent 8 är anordnad att uppställas med dess bakre ände på ett på marken anordnat stöd 9 och med sin främre ände medelst ett på nämnda lastkomponents botten medelst en vevanordning uppfällbart hjul- försett uppbärningsstöd 10, anordnat vid lastkomponentens centrum- linje. Vid lastkomponentens 8 bakre ände är, såsom bäst framgår av fig. 4, anordnade i sidled utskjutande partier ll och dessa utgöres av i vardera änden av en under nämnda lastkomponent 8 fästad genom- gående balk 11A. Funktionen av nämnda utskjutande partier skall närmare beskrivas längre fram.A load component 8 may, as shown in Figs. 1-4, be in the form of a box with an opening at the top. Said load component 8 is arranged to be arranged with its rear end on a support 9 arranged on the ground and with its front end by means of a wheeled support support 10 foldable on the bottom of said load component by means of a crank device, arranged at the center line of the load component. At the rear end of the load component 8, as best seen in Fig. 4, laterally projecting portions 11 are arranged and these are constituted at each end by a continuous beam 11A attached below said load component 8. The function of said protruding portions will be described in more detail later.

Funktionen av en sådan kärra l skall nu närmare beskrivas, varvid utgås från fig. 1, som visar lastkomponenten 8 i uppställt läge och kärran 1 i ett läge färdig att införas under nämnda lastkomponent 8. Kärrans l bakre delar och hjul 5 passerar vid backning av kärran l in under lastkomponenten 8 på vardera sidan om det nedfällda uppbärningsstödet 10. Kärran 1 7909946-1 kan därvid manövreras för hand och dess införning stoppas när var och en av de vid kärrans 1 bakre parti anordnade uppbärnings- ytorna 7 är belägna rakt under de i lastkomponentens 8 bakre del i sidled utskjutande partierna 11. Kärrans främre del upplyftes därefter, såsom framgår av fig. 2, och lastkomponentens 8 främre del understödjes därvid av kärrans 1 främre del på ovansidan av balkarna 4. Uppbärningsstödet 10 kan därvid uppvevas, så att det blir beläget i huvudsak parallellt med bottnen på lastkomponenten 8, såsom framgår av fig. 3. Kärrans 1 främre del nedsänkes där- efter, varigenom kärran svänges såsom en hävstång omkring hjulen 5, så att kärrans 1 bakre del och dess uppbärningsytor 7 svänges uppåt och att de utskjutande partierna och därmed lastkomponentens 8 bakre del upplyftes och blir fri från stödet 9. Kärran 1 med därpå uppburen lastkomponent 8 kan därefter köras iväg i pilens riktning.The function of such a cart 1 will now be described in more detail, starting from Fig. 1, which shows the load component 8 in the set-up position and the cart 1 in a position ready to be inserted under said load component 8. The rear parts and wheels 5 of the cart 1 pass when reversing the cart 1 under the load component 8 on each side of the lowered support support 10. The cart 1 can then be operated by hand and its insertion stopped when each of the support surfaces 7 arranged at the rear portion of the cart 1 is located just below the in the rear part of the load component 8 projecting laterally. it is located substantially parallel to the bottom of the load component 8, as shown in Fig. 3. The front part of the cart 1 is subsequently lowered, whereby the cart is pivoted as a lever around the wheels 5, so that the rear part of the cart 1 and its support surfaces 7 are pivoted upwards and that the projecting portions and thus the rear part of the load component 8 are lifted and become free from the support 9. The cart 1 with the load component 8 supported thereon can then be driven away in the direction of the arrow. .

Såsom framgår av fig. 5 är kärran 1 vid dess mitt delad genom att skänklarna 4 utgöres av sammankopplade balkar 4, som medelst exempelvis ett par hydraulcylindrar 4A på vardera skänkeln 4 är förskjutbara_i längdled. Avståndet mellan ytorna 7 ökar därvid då kolvarna pressas utåt, men minskar vid ihopdrag- ning. Därvid kan kärran 1 anpassas till olika stora lastkompo- nenter på ett enkelt sätt.As can be seen from Fig. 5, the cart 1 at its center is divided in that the legs 4 consist of interconnected beams 4, which by means of, for example, a pair of hydraulic cylinders 4A on each leg 4 are displaceable in longitudinal direction. The distance between the surfaces 7 then increases when the pistons are pressed outwards, but decreases when contracted. In this case, the cart 1 can be adapted to different size load components in a simple manner.

I fig. 6 är visad en ytterligare utföringsform av en kärra enligt uppfinningen. Denna kärra 1 är vid dess främre del försedd med ett flyttbart stödorgan 12, vars funktion närmare beskrives längre fram. Nämnda stödorgan 12 utgöres av åtminstone en mot kärrans centrumlinje vinkelrätt anordnad stödbalk 13, som är förskjutbar i kärrans längdríktning medelst en vinkelrätt mot stödbalken 13 i en hylsa 14 styrd styrbalk 15, som i sin mot- stående ände uppvisar ett manövreringshandtag 16. Detta stödorgan 12 kan, såsom visas på ritningarna, vara anordnat på undersidan av skänklarna 4 vid en kärra 1 av det slag, som beskrivits ovan och visas på fig. 1-5, men det kan även vara anordnat på skänk- larnas 4 motstående ovansida. Fördelen med att anordna stödorga- net 12 såsom visas på fig. 6 är bl.a., att stödbalken och uppbär- ningsytorna_7 blir belägna på en lägre nivå än i det fall som framgår av fig. 1-5. Detta genom att kärran 1 vänts upp och ned och genom att avståndet mellan hjulens 5 centrumaxel och ett plan 79099-46-1 genom uppbärningsytorna varieras. Beroende på vilken last som skall uppbäras kan tyngdpunktens höjdläge pá denna varieras genom om- vändning av vagnen mellan de i fig. 5 och 6 visade lägena.Fig. 6 shows a further embodiment of a cart according to the invention. This cart 1 is provided at its front part with a movable support member 12, the function of which is described in more detail later. Said support member 12 consists of at least one support beam 13 arranged perpendicularly to the center line of the cart, which is displaceable in the longitudinal direction of the cart by means of a guide beam 15 guided perpendicularly to the support beam 13 in a sleeve 14, which has an operating handle 16 at its opposite end. may, as shown in the drawings, be arranged on the underside of the legs 4 at a cart 1 of the type described above and shown in Figs. 1-5, but it may also be arranged on the opposite upper side of the legs 4. The advantage of arranging the support member 12 as shown in Fig. 6 is, among other things, that the support beam and the supporting surfaces_7 are located at a lower level than in the case shown in Figs. 1-5. This is done by turning the cart 1 upside down and by varying the distance between the center axis of the wheels 5 and a plane 79099-46-1 through the support surfaces. Depending on the load to be carried, the height position of the center of gravity on it can be varied by inverting the trolley between the positions shown in Figs. 5 and 6.

I fig. 7 visas en lastkomponent 17, som är avsedd att uppbära en båt B och vilken lastkomponent 17 är speciellt lämpad att transporteras på den i fig. 6 visade med flyttbart stödorgan 12 försedda vagnen. Sagda lastkomponent 17 består av vid dess ena ände i sidled utskjutande partier 18, på vilka är anordnade snett från dessa 18 mot varandra uppåt riktade uppbär- ningssträvor 19 avsedda att understödja bakre delen av en båt B.Fig. 7 shows a load component 17, which is intended to support a boat B and which load component 17 is particularly suitable to be transported on the carriage provided with movable support means 12 shown in Fig. 6. Said load component 17 consists of at its one end laterally projecting portions 18, on which are arranged obliquely from these 18 upwardly directed support struts 19 intended to support the rear part of a boat B.

I sagda lastkomponents motstående ände är vid dess centrumlinje anordnad en uppåtriktad i huvudsak U-formad del 20, som är avsedd att understödja båtbottnens B främre parti. Nämnda bakre 18, 19 och främre 20 uppbärningsstöd är därvid förbundna med varandra medelst förbindningsorgan 21. En svängbar stöddel 22 är därvid anordnad på nämnda förbindningsorgan 21 och är anordnad att stödja mot båtens köl 23.At the opposite end of said load component, an upwardly directed substantially U-shaped part 20 is arranged at its center line, which is intended to support the front part of the boat bottom B. Said rear 18, 19 and front 20 support supports are then connected to each other by means of connecting means 21. A pivotable support part 22 is then arranged on said connecting means 21 and is arranged to support against the keel 23 of the boat.

Funktionen av en sådan kärra framgår av fig. 8-10 och i princip tillgår pálastningen av lastkomponenten 17 och båten B på samma sätt som vid föregående exempel. Uppbärnings- stöden utgöres emellertid dock av klossar 24, som pallas under i det senare exemplet samt att den U-formade delens 20 nedre parti 25 är avsett att upplyftas och uppbäras av kärrans främre parti respektive understödjas av en på underlaget anordnad del 24. Om emellertid avståndet mellan de i V-form anordnade skänk- larna 4 blir för stort, vilket framgår av fig. ll, så att nämnda U-formade del 20 ej kan uppbäras av dessa, förskjutes medelst handtaget 16 den tvärställda balken 13 bakåt så att den 13 kan införas under förbindningsorganen 21. Lastkomponentens 17 främre del blir därvid uppburen på kärrans främre del av nämnda balk 13.The function of such a cart is shown in Figs. 8-10 and in principle the loading of the load component 17 and the boat B is accessed in the same way as in the previous example. However, the support supports consist of blocks 24, which are palletized below in the latter example, and that the lower part 25 of the U-shaped part 20 is intended to be lifted and supported by the front part of the cart or supported by a part 24 arranged on the ground. the distance between the legs 4 arranged in a V-shape becomes too large, as can be seen from Fig. 11, so that said U-shaped part 20 cannot be supported by these, the transverse beam 13 is displaced by means of the handle 16 so that the 13 can be inserted under the connecting means 21. The front part of the load component 17 is then supported on the front part of said beam 13 by said beam.

Ovan beskrivna kärror är lätta att handha och kan manövreras i läge under en lastkomponent även utan användning av ett fordon, varvid även uppbärningsstöden är borttagbara utan att ett fordon behöver vara anslutet till kärrans främre del.The carts described above are easy to handle and can be operated in position under a load component even without the use of a vehicle, whereby the support struts are also removable without a vehicle having to be connected to the front part of the cart.

Detta genom utformningen av kärran såsom en hävarm.This is through the design of the cart as a lever.

Uppfinningen är ej begränsad till de beskrivna och på ritningarna visade utföringsexemplen, utan kan varieras inom ramen för efterföljande patentkrav.The invention is not limited to the embodiments described and shown in the drawings, but can be varied within the scope of the appended claims.
