Description

Patentkrav: 1. Aktuator hvor der i en transmission mellem et aktiveringselement og en reverserbar elmotor (2) er indføjet en quick release for frikobling af aktiveringselementet (6) fra elmotoren og den del af tranmissionen, som ligger fra motoren til quick releasen, hvilke quick release omfatter to cylindriske koblingsdele (8,9) om hvilke, der ligger en koblingsfjeder (11) med udadbukkede ender, hvilke ender er forbundet med hver sit cylindriske element (12,13), lejret til, under normale forhold, at deltage i koblingens rotation, og hvor de to cylindriske elementer (12,13) med en udløser (14) er indrettet til at kunne bibringes en indbyrdes rotation for drejning af fjederens ender bort fra hinanden således, at fjederen (14) løsnes fra mindst den ene koblingsdel (8,9) for hel eller delvis udløsning af koblingen, kendetegnet ved, at de to cylindriske elementer (12,13) er forsynet med en udvendig fortanding, og at udløseren (14) har en modsvarende fortanding, som kan bringes i indgreb hermed til indbyrdes drejning af cylindrene. 2. Aktuator ifølge krav 1, kendetegnet ved, at de cylindriske elementer (12,13) er forsynet med en fortanding på den krumme flade. 3. Aktuator ifølge krav 2, kendetegnet ved, at de cylindriske elementer er forsynet med fortanding på en endeflade. 4. Aktuator ifølge krav 2 eller 3, kendetegnet ved, at fortandingen er rundtgående. 5. Aktuator ifølge krav 2 eller 4, kendetegnet ved, at bredden af fortandingen kun strækker sig over en del af længden af cylindrene (12,13). 6. Aktuator ifølge krav 1, kendetegnet ved, at udløseren (14) er Y-formet, hvor et første og andet (15) ben er udformet med en fortanding (20), som kan bringes i kontakt med fortandingen på henholdsvis det ene og det andet cylindriske element (12,13). 7. Aktuator ifølge krav 6, kendetegnet ved, at benene har et glat stykke fra hvor de spalter fra hinanden og et stykke ned, mens fortandingen (20) er anbragt på den yderste del af benene (15). 8. Aktuator ifølge krav 7, kendetegnet ved, at udløseren (14) er fjederbelastet (18) til at indtage en hvilestilling, hvor fortandingen )20)ikke er indgreb med de cylindriske elementer (12,13). 9. Aktuator ifølge krav 8, kendetegnet ved, at udløseren (14) er forbundet direkte eller indirekte med et kable (19) forsynet med et betjeningsgreb.
