Abstract:
In a clamp assembly for a tubular hose or cable, said clamp assembly comprisingan upper clamp half having a downwardly facing parting line face; a lower clamp half having an upwardly facing parting line face, said lower clamp half being positioned in a face to face relationship with the upper clamp half so that the parting line faces are side by side when the clamp assembly is in the closed position; a hinge pin pivotally connecting the clamp halves along a hinge edge, so that said clamp halves are movable from a clamp open position to a clamp closed position, a fastener mechanism for connecting the clamp halves along a latch edge when the clamp is in the clamp closed position; wherein the clamp halves, when positioned in the clamp closed position, define at least one passage therethrough for clamping a cylindrical object, wherein said passage has a longitudinal axis, the improvement of a fastener mechanism comprising an upper flange element protruding from the latch edge of the upper clamp half in a direction, when in the clamp closed position, generally laterally from the longitudinal axis of said passage, a lower flange element protruding from the latch edge of the lower clamp half in a direction generally laterally from the longitudinal axis of said passage, said lower flange element being in side-by-side relationship with the upper flange element when the clamp assembly is in the closed position, said lower flange element defining a passage for receipt of a carrier pin, a carrier pin rotatably positioned in the carrier pin passage, said carrier pin having a longitudinal axis and defining a transverse borehole for receipt of a locking bolt, and a locking bolt having a shaft portion positioned in the transverse borehole and extending radially therefrom, said locking bolt having a head portion spaced apart from the carrier pin, wherein the upper flange element and the lower flange element define a pair of aligned slots when the clamp assembly is in the closed position to permit the locking bolt to be pivotally moved from a disengaged position wherein the head of the locking bolt is laterally displaced from the lower flange element to a lockable position wherein the shaft of the locking bolt is positioned in the aligned slots, and wherein the head portion of the locking bolt is sized to contact the upper flange element when the locking bolt is in the lockable position so that threading the shaft portion of the locking bolt toward the carrier pin urges the upper flange element toward the lower flange element to lock the clamp assembly in the closed position.
