Claims (9)

Kraven
1. En handdriven kärra (1; 50) innefattande: - en långsträckt stödram (3; 52) och - ett par roterbara bärhjul (7) som är roterbart förbundna med en undre del (3b) avstödramen så att stödramen är svängbart anordnad i förhållande till bärhjulen mellan ettupprätt läge och ett bakåtlutat transportläge, varvid kärran innefattar åtminstone ettbärelement (6; 6a-c) anslutet till en övre del av stödramen (3; 52) och som skjuter ut framåtfrån stödramen, varvid stödramen är svängbart anordnad i förhållande till bärhjulen mellandet upprätta läget och ett framåtlutat lastläge, kännetecknat av att kärran innefattar tvåledade armar (28) som är svängbart förbundna med stödramen och ett par åtskilda vridbarastödhjul (22) anslutna till de ledade armarna och anordnade på avstånd (d2) från stödramen(3; 52) på en framsida av stödramen så att stödramen tillåts svänga i förhållande tillstödhjulen.
2. Kärran enligt krav 1, varvid stödramen (3; 52) är utformad så att det finns ett frittutrymme (10) under stödramen när stödramen är i upprätt läge för att tillåta stödramen attsvänga i förhållande till bärhjulen mellan det upprätta läget och det framåtlutade lastläget.
3. Kärran enligt något av föregående krav, varvid kärran innefattar en roterbar axel (26), somär roterbart förbunden med stödramen, och de ledade armarna (28) är fästa vid denroterbara axeln (26), varvid stödramen (3; 52) är anordnad att svänga i förhållande tillstödhjulen (22) kring rotationsaxeln.
4. Kärran enligt något av föregående krav, varvid stödhjulen (22) är anordnade på ettavstånd (d3) från varandra och så att fritt utrymme (24) bildas mellan stödhjulen ochstödramen (3); 52) för mottagning av behållaren.
5. Kärran enligt något av föregående krav, varvid kärran innefattar ett fjäderarrangemang(38) anordnat mellan stödhjulen (22) och stödramen (3; 52) så att en fjäderkraft verkar påstödramen i riktning bakåt när stödramen är i det framåtlutade lastläget.
6. Kärran enligt krav 5, varvid kärran innefattar åtminstone ett handtag (5) anslutet till enövre ände av stödramen, varvid bärhjulens (7) lägsta punkter (12) och de lägsta punkterna(42) hos stödhjulen (22) definierar ett plan, kärran intar ett viloläge när det inte finns någonkraft som verkar på handtaget och nämnda fjäderarrangemang är frilagt, och stödramen (3;52) lutar en vinkel (oL) mellan 5° och 15° i en framåtriktning med avseende på en axelvinkelrätt mot nämnda plan när kärran är i viloläget.
7. Kärran enligt något av de föregående kraven, varvid nämnda åtminstone ett bärandeelement innefattar åtminstone två åtskilda bärelement (6a-c).
8. Kärran enligt något av föregående krav, varvid nämnda åtminstone ett bärelement (6; 6a-c) har en yttre del (35) och den yttre delen är rak.
9. Användning av kärran (1) enligt något av kraven 1 - 8 för att bära flexibla intermediärabulkbehållare (45) försedda med minst en ögla (46), varvid stödramen tippas mot behållarentill det framåtlutade lastläget och bärelementet (6; 6a-c) träs in i behållarens åtminstone enögla (46), och kärran tippas bakåt till upprätt läge medan den flexibla behållaren sträcks i envertikal riktning, varvid stödhjulen (22) och bärhjulen (7) förblir i kontakt med markenmedan stödramen lutas framåt och bakåt mellan det upprättstående läget och detframåtlutade lastläget.
