ABSTRACT:
A pipe coupling device for coupling the peripheral flanges of a pair of pipes together, including a pair of retainers with a V-shaped groove therein for receiving portions of the peripheral flanges of the pipes. The retainers are pivotally coupled at one of their ends by a hinge assembly and releasably coupled at their opposite ends by a latch mechanism. The hinge assembly has at least two links pivotally coupled at one of their ends to one of the retainers by a first pivot pin and pivotally coupled at their other ends to the other retainer by a second pivot pin. The pivot pins are separated from each other such that the links of the hinge assembly straddle the peripheral flanges of the pipes. This arrangement provides more uniform pressure at the ends of the retainers since the moment resulting from the offset of the hinge assembly is moved closer to the circumferential loading line between the retainers and the flanges of the pipe. In a second embodiment, the retainers are pivotally coupled together at one of their ends by a single pivot pin and releasably coupled together at their other end by a canted latch mechanism.
