Abstract: A coupling assembly that includes: a) a female coupling member including a cavity opening onto its receiving end, where the cavity has an annular groove; b) a male coupling member including an annular rib, the rib having a tapered leading edge, a trailing edge and a maximum diameter between the leading and trailing edges; c) a diametrically expandable locking ring carried in the annular groove of the female coupling member; and d) an annular collar slidably carried on the male coupling member axially between the trailing edge of the annular rib and the trailing end of the male coupling member, where the annular collar includes an outer circumferential surface having an outer diameter substantially equal to or greater than the maximum diameter of the annular rib and where the annular collar is slidable on the male coupling member from an unlocked position, in which the collar is positioned axially against the annular rib providing a relatively smooth circumferential surface from the trailing edge of the annula

Abstract: A quick connect/disconnect coupling assembly includes: (a) a female coupling member including a cavity opening onto its receiving end, where the cavity has an annular groove; (b) a male coupling member including an annular rib, where the rib has a tapered leading edge, a trailing edge and a maximum diameter between the leading and trailing edges; (c) a diametrically expandable locking ring carried in the annular groove of the female coupling member, where the locking ring has an unexpanded inner diameter that is less than the maximum diameter of the annular rib on the male coupling member, and where the locking ring is diametrically expandable to have an inner diameter that is slightly larger than the maximum diameter of the annular rib on the male coupling member; (d) a dial carried for rotation in the male coupling member; and (e) a mechanical actuator carried on the male coupling member operatively coupled to the dial such that the mechanical actuator extends radially outwardly with respect to the male cou

Abstract: A quick connect/disconnect coupling assembly includes (a) a female coupling member; (b) a male coupling member including an annular rib; (c) an expandable locking ring carried by the female coupling member, where the locking ring has an unexpanded inner diameter that is less than the maxinium diameter of the annular rib, and has an inner diameter slightly larger than the maxinum diameter of the annular rib when expanded; (d) a rotatable dial carried on the male coupling member; and (e) a mechanical actuator including an axial lever coupled to the dial such that the axial lever extends radially outwardly upon rotation of the dial in a first direction to uncouple the male coupling member from the female coupling member, and retracts inwardly with respect to the male coupling member upon rotation of the dial in an opposite direction to couple the male coupling member to the female coupling member.
