ABSTRACT:
A coupling system is provided that includes a male coupling having a cylindrical distal end including a recess that includes follower surfaces, a female coupling having a cylindrical interior for receiving the distal end of the male coupling, and a pair of opposing jaw members movably mounted within the interior and including external cam surfaces for engaging the follower surfaces of the male coupling when the jaw members are radially moved apart, and a drive train for radially and forcefully moving the jaw members apart. The drive train includes a wedging ball that freely floats in recesses between the opposing jaw members, and a drive rod for axially moving the wedging ball into and out of engagement with wedge surfaces located in the interior of the jaw members. The drive rod includes a distal end having a bore for slidably receiving the wedging ball. The free-floating of the wedging ball within the drive rod bore and between the internal surfaces of the jaw members allows it to apply uniform wedging forces to the jaw members when spreading them apart into a coupling position.
