  • Rock climbing simulator apparatus
    Patent number: 7727118
    Abstract: An improved rock climbing simulator that uses an adjustable fluid resistance apparatus coupled to an axle of a rotating climbing surface to control the rate of rotation of the climbing surface and thus the perceived climbing speed experienced by the climber. The fluid resistance apparatus is structured to control the rate of rotation of the climbing surface, and hence the perceived climbing speed, regardless of the weight or position of a climber on the climbing surface.
