Abstract
The rope grab uses friction to control movement along the rope. A brake has an eye at one end and a foot at the other that extends away at an angle to a rounded toe. Optionally, the eye and foot are attached so as to swivel. A cam has an oval rocker and a lever that extends from the rocker opposite the rocker surface. The rocker surface curves eccentrically about an axis, so the rocker behaves like a cam to modulate friction on the rope. The rope extends through a slot and is pinched between an operative surface of the rocker surface and the toe. The brake and cam are held in the correct position relative to each other between two parallel walls of a housing with the eye and lever extending in generally opposite directions outside the housing. Optional springs bias the brake toe and operative surface into the slot.
