Claims (8)

1. Rotorvinge (1) til en vindmølle, som har et langstrakt vingebasislegeme (2) med et antal af forbindelseselementer (5), som hver især omfatter mindst en forbindelsesdel (7), som strækker sig aksialt, og som er udformet således, at den forbindes med tilsvarende forbindelsesdele af et rotornav af en vindmølle, kendetegnet ved, at forbindelseselementerne (5) er forbundet i en periferisk retning, således at der skabes en lukket ringform, hvor hvert forbindelseselement (5) omfatter mindst et forbindelsesmiddel, der strækker sig periferisk, til at forbinde det respektive forbindelseselement (5) med et tilsvarende forbindelsesmiddel, der strækker sig periferisk, af mindst et forbindelseselement (5), der er anbragt tilstødende, hvor forbindelsesmidlet, der strækker sig periferisk, tilvejebringer en mekanisk stabil forbindelse med hensyn til samlingen af respektive forbindelseselementer (5), der periferisk er anbragt tilstødende.
2. Rotorvinge ifølge krav 1, hvor forbindelseselementerne (5) har en ring-segment-lignende form.
3. Rotorvinge ifølge et af de foregående krav, hvor hvert forbindelseselement (5) omfatter mindst et forbindelsesmiddel, der strækker sig radialt, til at forbinde et respektivt forbindelseselement (5) med et tilsvarende forbindelsesmiddel, der strækker sig radialt, af mindst et ringelement (11,12), som har en radialt udvendig og/eller indvendig position i forhold til forbindelseselementerne (5).
4. Rotorvinge ifølge et af de foregående krav, hvor forbindelsesmidlet, der strækker sig periferisk og/eller strækker sig radialt, er opbygget som et form-lukkeelement.
5. Rotorvinge ifølge krav 4, hvor formlukkeelementet er opbygget som et fremspring (8) eller en tilsvarende indskæring (9), især et svalehale-lignende fremspring eller en svalehale-lignende indskæring.
6. Rotorvinge ifølge krav 5, hvor forbindelsesmidlet, der strækker sig periferisk, er anbragt tilstødende op til den radialt udvendige eller indvendige rand af et respektivt forbindelseselement (5) i forhold til midteraksen af rotorvingen.
7. Rotorvinge ifølge et af de foregående krav, hvor et forbindelseselement (5) har en symmetrisk eller en asymmetrisk form i forhold til dets længdeakse (10), der periferisk er rettet ind.
8. Vindmølle, omfattende et rotornav, som har mindst en rotorvinge (1) ifølge et af de foregående krav knyttet dertil.
