ABSTRACT:
Self-belaying apparatus. An apparatus for permitting sport climbing without the assistance of a belayer is described. While the user is climbing, the apparatus slides along the climbing rope with little resistance. Any downward motion is immediately stopped, however. When the climber wishes to continue ascending, the apparatus automatically releases its grip on the rope. The apparatus, which includes a base, an elongated bar, a flat plate and a pulley, can also be used for rapelling.
