Abstract: A downwardly opening canopy is provided and supported from an inflatable skeletal frame including a generally rectangular base portion and crossed-intersecting inflatable arch members. The canopy is constructed of translucent material and has an ocean ship sailing scene, in color, thereon with the scene being visible from within and from without the canopy. A yieldably supported pedestal is mounted within the area enclosed by the canopy and rotatably mounts a simulated ship's wheel therefrom. In addition, a compass pointer is rotatably journalled from the upper portion of the pedestal and the ship's wheel is drivingly connected to the compass needle for rotating the latter responsive to rotation of the ship's wheel.

Abstract: Support structure is provided for support in elevated position above a support surface upon which a user may be disposed. An elongated section of flexible tension member is mounted from the support structure by guide structure mounted thereon and the tension member includes releasably joined opposite ends. The tension member is supported from the guide structure for longitudinal shifting relative thereto and with a closed loop of the tension member depending downwardly from the support structure. The guide structure includes adjustable friction brake structure for yieldingly braking the tension member against longitudinal shifting relative to the guide structure With the brake structure adjustably applied, the reach of the tension member furthest from the support structure may be used by a climber and the friction braking on the tension member may be adjusted to effect a friction drag against longitudinal shifting of the tension member which is equivalent to less than the weight of the user.
