Claims (9)

Patentkrav
1. 1. Sugeankersystem omfattende en caisson (2) med en topplate (1) og en åpen nedre ende,
karakterisert ved en støttestruktur festet til caissonens (2) nedre ende, støttestrukturen omfatter et antall ribber (4) som hengslet støtter et antall bevegelige luker (3), hvori de bevegelige lukene (3) er tilpasset til å ta en vertikal orientering under installasjon og jordinntrengning, og kan beveges til en horisontal posisjon for å øke sugeankersystemets lastekapasitet.
2. Sugeankersystemet ifølge krav 1, hvori de bevegelige lukenes (3) orientering kan reverseres for uthenting.
3. Sugeankersystemet ifølge krav 1, hvori caissonen (2) er løsbar fra støttestrukturen ved hjelp av en mekanisme.
4. Sugeankersystemet ifølge krav 1, videre omfattende en andre støttestruktur uten luker plassert nær caissonens (2) topp.
5. Sugeankersystemet ifølge krav 1, hvor hver luke (3) omfatter to sektorformede sideplater forbundet med en buet endeplate, sideplatene er hengslet til støttestrukturen.
6. Sugeankersystemet ifølge krav 5, hvor hver ribbe har en V-form med mindre veggtykkelse i bunnen enn på toppen for å minimere gjennomtrengningsmotstand.
7. Sugeankersystemet ifølge krav 5, hvori ribbene (4) er utformet med buede øvre flater som vender mot lukenes (3) endeplater.
8. Sugeankersystemet ifølge krav 5, hvor lukene er hengslet på en slik måte og har en form som gjør at lukekanten følger banen til en sirkel under åpning og lukking for minimal jordmotstand.
9. Sugeankersystemet ifølge hvilket som helst av de foregående kravene, hvori 2, 3 eller 4 sugeankere er forbundet sammen og skaper større områder med lukkede luker for økt lastekapasitet.
