Patent attributes
A multi-coupling system includes first and second multi-coupling components that can be connected and disconnected. When connected, opposing fluid couplers on the components are connected. The second multi-coupling component has a handle assembly including a hook retainer, and the first coupling component has a roller, and the handle assembly is rotatable to connect and disconnect the components. As the handle assembly rotates for connection, the hook retainer interacts as a single cam with the roller to pull the components together. A locking pin assembly has a locking pin that is moveable between extended and retracted positions, and when extended locks in a housing of the second component to prevent rotation of the handle assembly. A user manipulates the locking pin assembly to retract the locking pin, which is automatically retained in the retracted position. The locking pin automatically resets when the handle assembly is rotated to disconnect the multi-coupling components.
