Abstract:
1. A locking device for coupling an elongate member to an assembly, the locking device comprising: a. an outer frame adapted to be fixed to the assembly, the outer frame comprising at least one side plate extending from a portion of the assembly, the plate including an elongate member receiving recess; b. a clamp comprising at least one clamp plate, the clamp plate including a member retention surface and a stop surface, and at least one rotating link coupler, the rotating link coupler including an orifice surrounded by an engagement surface, the clamp coupled to the side plate of the outer frame so that the clamp is rotatable relative to the outer frame; c. an actuator comprising at least one actuator plate having a second stop surface, at least one rotating link coupler, the rotating link coupler including an orifice surrounded by an engagement surface, the actuator coupled to the side plate of the outer frame so that the actuator is rotatable relative to the outer frame; d. a link comprising a bolt having a shaft passing between the hole of the rotating link coupler of the clamp and the hole of the rotating link coupler of the actuator and a compression spring surrounding the shaft of the bolt, the spring having a first end engaging the engagement surface of the rotating link coupler of the clamp and a second end engaging the engagement surface of the rotating link coupler of the actuator, wherein when an elongate member is positioned in the elongate member receiving recess of the outer frame, rotation of the actuator in a first direction causes the link to rotate the clamp into a first position, further rotation of the actuator in the first direction causes the actuator link and clamp to reach an over center position locking the elongate member in the elongate member receiving recess, and rotation of the actuator in a second direction causes the link to rotate the clamp into a second position freeing the elongate member so it is removable from the elongate member receiving recess; and e. a linear actuator operatively coupled between the outer frame and the actuator for selectively rotating the actuator in the first and second directions.
