Claims (31)
1. Drej eled (100), der omfatter: (a) en spindel (110), der har en øvre (120) og nedre (130) endesektion og er forbundet med og kan dreje sammen med øvre (85) og nedre (86) bore- eller arbejdsstreng-(60) sektioner, hvor spindlen (110) indbefatter en langsgående passage (160), der danner en forlængelse af en passage i bore- eller arbejdsstreng- (60) sektionerne; og (b) en bøsning (300) med en langsgående bøsningspassage, hvor bøsningen (300) er drejbart og i frem- og tilbagegående bevægelse forbundet med spindlen (110) af et par langsgående adskilte lejer (1100), hvor drejeleddet (100) indbefatter et hurtigt låsning/-oplåsningssystem (3000), der aftageligt forbinder bøsningen og spindlen, hvor i en låst tilstand det hurtige låsning/-oplåsningssystem reducerer niveauet af relativ langsgående bevægelse mellem bøsningen og spindlen sammenlignet med en ulåst tilstand; og (c) en tætning (1300) mellem den øvre og nedre endedel af spindlen (110) og bøsningen (300).
2. Drejeled (100) ifølge krav 1, hvor det hurtige låsning/oplåsningssystem (3000) har låste og oplåste tilstande og er i stand til at blive låst og oplåst flere gange, og bøsningen (300) og spindlen (110) bevæger sig frem og tilbage på langs i forhold til hinanden, når det hurtige låsning/-oplåsningssystem (3000) er i en ulåst tilstand, og bøsningen (300) kan dreje i forhold til spindlen (110) i både den låste og oplåste tilstand.
3. Drejeled (100) ifølge et hvilket som helst af de foregående krav, hvor bøsningen (300) indbefatter mindst én lukning (326), hvor lukningen (326) tjener til at begrænse langsgående bevægelse af bøsningen (300) i forhold til en ringformet sikkerhedsventil (70), når drejeleddet (100) er aftageligt forbundet med den ringformede sikkerhedsventil (70).
4. Drejeled (100) ifølge krav 3, hvor bøsningen (300) indbefatter to adskilte lukninger (326, 328), hvor hver lukning (326, 328) tjener til at begrænse langsgående bevægelse af bøsningen (300) i forhold til den ringformede sikkerhedsventil (70), når drejeleddet (100) er aftageligt forbundet med den ringformede sikkerhedsventil (70), men hver lukning (326, 328) begrænser langsgående bevægelse i den modsatte retning sammenlignet med den anden lukning (328, 326).
5. Drejeled (100) ifølge et hvilket som helst af de foregående krav, hvor det hurtige låsning/-oplåsningssystem (3000) indbefatter en fjeder (3120) og en fjederlukning (3400) mellem bøsningen (300) og spindlen (110).
6. Drejeled (100) ifølge krav 5, hvor fjederen (3120) indbefatter flere fingre (3120).
7. Drejeled (100) ifølge krav 5 eller 6, hvor fjederlukningen (3400) indbefatter en kontaktoverflade (3400), hvilken kontaktoverflade (3400) har mindst én åbning eller rille (136) til at gøre det muligt for fluid at strømme hen over mindst en del af overfladen (3400).
8. Drejeled (100) ifølge krav 6 eller 7, hvor spindlen (110) indbefatter en rampe (3420) og låsefordybning (3460), hvilken låsefordybning (3460) operativt er forbundet med flere fingre (3120).
9. Drejeled (100) ifølge et hvilket som helst af kravene 5 til 8, hvor fjederen (3120) indbefatter en låsering, og spindlen (110) indbefatter en låsefordybning (3460), og spindlen indbefatter et rillet område (135).
10. Drejeled (100) ifølge et hvilket som helst af kravene 6 til 9, hvor det hurtige låsning/-oplåsningssystem (3000) indbefatter et greb (3600), der drejbart justerer fjederen (3120) efter lukningen (3400).
11. Drejeled (100) ifølge et hvilket som helst af kravene 5 til 10, hvor fjederen (3120) kan rotere i forhold til bøsningen (300).
12. Drejeled (100) ifølge et hvilket som helst af kravene 5 til 11, hvor spindlen (110) indbefatter en låseposition og fjederen (3120) låses ved at bevæge bøsningen (300) på langs til låsepositionen.
13.
