IMPROVEMENTS RELATING TO ANCHORS FOR ROCK CLIMBING

摘要

An anchor for use in rock climbing is designed to be installed by the lead climber and removed when it is no longer required, thereby minimizing the environmental impact of its use and giving rise to no legal liability problems. The anchor comprises a mounting plate (2) to one side of which there is secured an expansion bolt (1) and on the other side of which there is provided a quick-release operating lever (3) for the bolt. During a climb, the lead climber anchors himself to the rock face by drilling a bore in the rock face, inserting the expansion bolt (1) into the bore and operating the lever (3) to expand the bolt. The tail climber subsequently removes the anchors fitted by the lead climber and so the route is left clean. Such anchors also have utility in the building and construction industries.
