Patent ID: 7681925

Claim:
A quick disconnect coupling comprising: a coupler assembly having a generally tubular body; an inlet portion and a generally cylindrical outer surface portion including a pair of radially outwardly-directed pins; and a nipple assembly having a generally tubular body; an inner body end; a push-to-connect mechanism including: a cup-shaped member concentrically surrounding said inner body, the cup-shaped member having a pair of opposed slots each including an entry slot portion and a locking slot portion having a proximal end connected to the entry slot portion and a distal end, and the cup-shaped member being rotatably journalled on said nipple assembly tubular body for limited rotational pivoting relative thereto; and a biasing member normally biasing said cup-shaped member in a first rotational direction to an at-rest position relative to said nipple assembly tubular body, wherein with said nipple inner body end being sealingly received within said coupler assembly, said coupler and nipple assemblies are interconnected via said coupler assembly pins each being received through a respective one of said entry slot portions and advanced therethrough into a respective one of said locking slot portions of said nipple assembly cup-shaped member, and wherein as the pins are advanced through the entry slot portions, the cup-shaped member is pivoted by the engagement of the pins with the entry slot portions in a second rotational direction opposite the first rotation direction allowing the pins to be received into the locking slot portions whereupon the biasing member returns the cup-shaped member back to its at-rest position disposing the pins in the distal end of said locking slot portion and locking the nipple assembly to the coupler assembly.
