Image Number 2 for United States Patent #6418592.
A rope gripper for connecting for example a rope operated switch to a rope. The gripper comprises a body defining a passage into which a rope can be inserted. Two jaws are mounted eccentrically on pivot pins on either side of the passage and biased towards the passage such that they are pressed against an inserted rope. The jaws are shaped and mounted such that movement of an inserted rope in one direction along the passage drives the jaws towards the rope, causing the rope to be jammed within the passage, whereas movement of the rope in the opposite direction along the passage drives the jaws to a position in which the rope is free to slide.
