Abstract:
1. An apparatus for securely engaging a surface through the application of friction comprising: a first friction pad comprising a first contact surface and a first backing structure, wherein said first backing structure stabilizes said first contact surface, and wherein said first friction pad is coupled to a first pivot arm; a second friction pad comprising a second contact surface and a second backing structure, wherein said second backing structure stabilizes said second contact surface, and wherein said second contact surface comprises said high friction grip material, and wherein said second friction pad is connected to a second pivot arm; an outer member comprising a first cavity, a first open end, and a second closed end coupled to said first friction pad through said first pivot arm; an inner member comprising a second cavity, a third open end, and a fourth closed end coupled to said second friction pad through said second pivot arm, wherein said inner member partially resides within said first cavity of said outer member to provide a first clamping force, wherein said inner member and said outer member each reside on a common longitudinal axis, and wherein said first friction pad is diametrically opposed to said second friction pad and each of said first friction pad and said second friction pad reside on said common longitudinal axis; a control device for activating said outer member and said inner member to provide said first clamping force; and means for retracting said outer member towards said inner member when said control device is not activated, wherein said control device comprises a plurality of first and second pulley assemblies coupled with a pulley line for controlling movement of said outer and inner members.
