发明名称 Extendable rope protecting sleeve
摘要 An extendable rope protecting sleeve is provided as an apparatus that extends over an existing climbing rope providing a barrier that protects said climbing rope from fraying and weakening as a result of direct contact with damaging surfaces. The expandable rope protecting sleeve shrouds a climbing rope during a climber's descent with minimal interference to the climber's range of motion. The apparatus provides the extendable sleeve with a detachable engagement through a breakaway wrist strap in order reduce the likelihood of the climber being encumbered by the apparatus. Additionally, the detachable engagement is provided in a manner that avoids a sudden jerking sensation upon detachment. Through the combination of the aforementioned components the apparatus is able to slowly expand over a climbing rope covering exposed sections of the climbing rope during the climber's descent.
