At least one moveable member has an engagement surface for engaging with an adapter that is positionable within the interior space of the housing. One or more ramps are defined on the ring for (i) moving the engagement surface of the moveable member toward the central longitudinal axis upon moving the ring in one direction in order to engage the coupling to the adapter, and (ii) moving the engagement surface of the moveable member away from the central longitudinal axis upon moving the ring in an opposite direction in order to disengage the coupling from the adapter.

  • Patent number: 5462316
    Abstract: A quick action coupling is provided of male and female coupling parts in which spherical camming members are loosely retained in a multiplicity of circumferentially disposed openings extended radially through the wall portion of the female coupling member. An axially movable collar surrounding the cylindrical wall portion of the female coupling member has an internally disposed camming surface portion which is configured to cam the spherical members radially inwardly upon movement of the collar in the direction of the open end of the coupling member. The male coupling member is provided with an annular end portion interfacing with a compressible sealing ring in the female coupling portion and further has an upwardly open groove disposed in alignment with the spherical members when the end surface portion is in interfacing relationship with the sealing ring.
