Abstract:
An actuator device operable to retract the cam elements of a spring-loaded camming device (SLCD) used in the sport of rock climbing. The actuator includes a remote finger and a remote thumb. The remote finger is mounted in a handle to permit translation of the remote finger along an axis, and rotation of the remote finger about that axis. In use, the remote finger can be rotated to present a narrow profile to pass between the trigger bar of a SLCD and a wall of a crack. Subsequent to its insertion behind the trigger bar, the remote finger can be rotated by about 90 degrees to capture the trigger bar. Then, the remote finger and remote thumb can be urged toward each other, effective to squeeze the SLCD and rotate its cam elements, to effect removal of the SLCD from the confines of the crack.
