MULTI-PURPOSE ADJUSTABLE-INCLINE CLIMBING WALL
Embodiments of the present invention are directed to an adjustable-incline climbing wall. The climbing wall comprises one or more climbing panels supported by a frame and a system for adjusting the incline of the frame to provide a climbing wall of a desired incline. The incline of the climbing wall may be adjusted by activating an actuator, which extends the upper portion of the frame a distance from a support wall, tilting the climbing wall to a desired incline. When the climbing wall is substantially vertically oriented, the system for adjusting the incline of the climbing wall may extend only a small distance from the support wall so that the adjustable-incline climbing wall has a relatively small footprint. In some embodiments, the climbing wall may also comprise one or more fitness accessories that can brought to an optimal height for a particular user through adjustment of the climbing wall incline.
