Abstract
The present invention relates to an active camming device including a plurality of non-flat camming surfaces. In accordance with the present invention, the opposing camming surfaces are shaped to include substantially concave and convex surfaces respectively. In one embodiment, each individual cam lobe is shaped in a substantially concave or convex manner to form a cam surface. In another embodiment, a plurality of cam lobes disposed on a single side of a device, are shaped to provide a combined substantially concave or convex surface. The convex surface or surfaces are always disposed opposite of the concave surface or surfaces to provide an increased stability in uneven recesses. Non-flat camming surfaces increase the stability of a camming device in irregular recesses by increasing the number of connection points between the device and the recess.
