Patent attributes
A coupling includes a housing having a wall defining an interior space and extending along a central longitudinal axis. A ring is movably mounted with respect to the wall. 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.
