Abstract: An artificial climbing tree assembly consisting of one or more artificial climbing trees will be constructed of a steel pipe or tubular framework, in segments or welded together, covered with molded segments having the outward appearance of a natural tree trunk texture. The trees will be attached to a base plate with a central support tower housing a safety belaying and repelling system. The unique safety incorporated into the invention is created by the inclination of the trees away from the top of the central support tower. A tether line attaches from the back of the climber to the top of the tree through a pulley system in the extension arm to the safety belaying and repelling system housed by the central support tower. The climbers are required to climb the face of the trees, where if they let go, they will fall away from the tree and will be slowly lowered by the safety belaying and repelling system to the foam-cushioned pad below.

Abstract: This new and unique adjustable cantilevered aquatic exercise device offers a clean modern appearing device for exercising on the side of a swimming pool or from the end of a diving board. By mounting two extension arms to two horizontal support arms connected and mounted to the pool deck surface by mounting plates, angle-mounting brackets or slid over the end of the diving board, a single exercise bar may be relocated between pluralities of orifices on the extension arms to achieve a wide variety of elevations to exercise at the side of a swimming pool. This device can be pivoted back from the edge of the pool and remains completely out of the water when in use, not requiring the need to be constructed from expensive materials, and may be finished with a wide variety of rust preventative and cushioned coatings.

Abstract: A variably curved track-mounted amusement ride having, in a first embodiment, at least one outside curve and at least one inside curve, each lying substantially within a vertical plane and each having an axis of symmetry which is substantially horizontal. The vertical distance occupied by an outside curve is less than that occupied by an inside curve. The track can retain a cart which runs on the track no matter what the orientation of the body of the cart is with respect to the track. Any means that is well known in the art can be used to raise the cart to the beginning of the track. No portion of the track, except optionally the lowest level, lies directly below at least the farthest outside portion of an outside curve. A second embodiment has only outside curves.
