Abstract
An anchoring device for use in a rock-crevice defined by a first rock wall and an opposing second rock wall. The anchoring device comprises an axle member having a longitudinal axis. A first cam is rotatable about the longitudinal axis of the axle member and contactable with the first rock wall with the first cam having a first side wall and a second side wall. A second cam is rotatable about the longitudinal axis of the axle member and contactable with the second rock wall with the second cam having a first side wall and a second side wall. The first side wall of the first cam is aligned with the first side wall of the second cam and the second side wall of the first cam is aligned with the second side wall of the second cam. Upon a first force being applied to the first cam by the first rock wall and a second force being applied to the second cam by the second rock wall in a direction generally toward the longitudinal axis, the axle member is free from any created moment.
