KNEE ASCENDER ASSEMBLY FOR ROPE CLIMBING

摘要

A secondary ascender system for use in rope climbing and with other rope climbing systems that provides a knee ascender permitting full range of motion and energy capture from two legs by encasing an interior portion of the length of an elastic cord used for tending the knee ascender within a load bearing member. The load bearing member connects a foot attachment to an ascender and transfers loads applied to the foot attachment and via the elastic cord during tending to the ascender to advance up the rope.

主权项

1. A knee ascender apparatus comprising:
an elastic cord having a fixed end and a free end defining a length; a load bearing member having a hollow core open at an aperture, wherein the fixed end of the elastic cord is secured relative to the load bearing member, an interior portion of the length of the elastic cord extends from the fixed end through the hollow core to the aperture, and an exterior portion of the length of the elastic cord extends through the aperture to the free end external to the load bearing member; a pulley positioned within the hollow core opposite the aperture around which the interior portion of the length of the elastic cord extends; an ascender secured to the load bearing member adjacent to the aperture; and a foot attachment depending from the load bearing member.
