Abstract:
A system for use by at least one climber, the system comprising:an artificial climbing structure having at least one route defined by a series of artificial rock climbing holds, the climbing structure simulating a rock surface and the route simulating a rock climbing route; a flexible member having a first end attachable to a climber; a first pulley assembly affixed to the artificial climbing structure; a second pulley assembly, the flexible member having a plurality of windings extending between the first pulley assembly and the second pulley assembly; a mechanism coupling the second pulley assembly to the artificial climbing structure, the mechanism urging the second pulley assembly away from the first pulley assembly with a first force so as to avoid slack in the flexible member when the climber moves upward the mechanism resisting movement of the second pulley assembly toward the first pulley assembly with a second force which is larger than the first force so as to inhibit injury to the climber when the climber is supported by the flexible member, wherein the second pulley assembly travels along a pulley path when the climber climbs; and a guide member extending along the pulley path, the guide member coupled to the second pulley assembly and inhibiting the second pulley assembly from twisting.
