Arrangement for imparting motion through counter-rotation of opposing end terminations of arched flexible member

摘要

An arrangement for imparting translational movement of a load with respect to a columnar structure that takes the form of at least one flexible elastic member (e.g., bungee cord) that is disposed to surround a portion of the structure and a platform coupled to the opposing ends of the flexible elastic member. The platform is used to support the load and the ends of the flexible member are coupled to the platform in a manner such that the ends are free to rotate. Thus, the application of counter-rotational forces to these opposing end terminations will impart a tension to the flexible elastic member that ultimately causes the flexible member to flip over to relieve the tension. By continuing to apply the counter-rotational forces, the flexible member will continue to flip, and progress in translational movement along the columnar structure.

1. An arrangement for imparting translational movement of a load with respect to a structure associated therewith, the arrangement comprising
at least one flexible elastic member disposed to surround a portion of the structure, the flexible elastic member defined as having opposing end terminations; and a platform coupled to the opposing ends of the flexible elastic member and used to support the load, the platform including means for imparting counter-rotational forces to the opposing end terminations of the flexible elastic member sufficient to impart a tension to the flexible elastic member that is relieved by causing the flexible elastic member to flip over and translate along the structure.
