ABSTRACT:
A coupling device for rotatably coupling poles of a tepee tripod. A first clamp clamps onto an upper end of a first pole. A second clamp clamps onto an upper end of a second pole. A third clamp clamps onto an upper end of a third pole. First and second rotatable couplers rotatably couple the first clamp to the second clamp, and the first clamp to the third clamp. The first coupler is rotatable about a first axis of rotation, so as to allow relative rotation between the first and second clamps. The second coupler is rotatable about a second axis of rotation so as to allow relative rotation between the first and third clamps. The first and second axes of rotation lie in a plane generally perpendicular to a first longitudinal axis corresponding to the first pole when the first clamp is clamped onto the first pole. The first and second axes of rotation intersect the first longitudinal axis. The first and second axes of rotation are radially spaced apart relative to the first longitudinal axis.
