Patent ID: 8807602

Claim:
A fluid coupling assembly comprising: a hose nipple with a distal flange and a nipple neck, the nipple neck of a narrower diameter than a diameter of the distal flange, a box having a socket into which the hose nipple fits upon coupling, a yoke, which is open to one side, is of a narrower inner diameter than said diameter of the distal flange and can receive and hold said nipple neck, a lever mechanism actuatable to pull said yoke axially from an open extended position toward said box to a closed retracted position, to pull said hose nipple, when the nipple neck is held in said yoke, into full engagement with said socket, further including: a plurality of guide bolts, each of the guide bolts having a guide bold axis, the guide bolt axis for each of the guide bolts being substantially parallel to every other one of the guide bolt axis, each guide bolt axis being substantially parallel to and symmetrically distributed about a central axis of the fluid coupling assembly, wherein the central axis is parallel to a longitudinal axis of the hose nipple when assembled, and wherein each of the plurality of guide bolts is fixed to the yoke and extends through the box; a locking plate located on an end of the box opposite the yoke, the locking plate movable perpendicular to said central axis between an unlocked position permitting axial movement of said guide bolts and a locking position locking each of the guide bolts from axial movement, wherein the locking plate directly engages each of the plurality of guide bolts when the locking plate is in the locking position and thereby locking said hose nipple in full engagement with said socket.
