Abstract: A base running ball game has combined paddle and bat implements to hit a ball. Offensive players use the combined paddle bat to hit the ball into a fairfield occupied by defensive players. Some of the defensive players use the combined paddle and bat implement to field the batted ball and send the ball into safe areas of bases. A put out is made when the ball lands in the safe area of a base in front of a batter running to the base.

Abstract: A geodesic frame assembly and method of making a frame assembly with a plurality of identical hub assemblies interconnected with flexible struts. The hub assemblies have rotatable members connected to ends of the struts. The struts are attached to the members along chord lines so the members rotated during erection of the frame assembly. A cable operably connected to a winch cooperates with outer hub assemblies to erect the frame assembly and hold the frame assembly in the erected configuration.

Abstract: A frame assembly and method of making a frame assembly over an area with a plurality of strut assemblies connected to hubs and peripherally located anchors. The hubs pivotally connect the adjacent ends of the strut assemblies to complete a network of hubs and strut assemblies covering the surface. Each strut assembly has a leaf spring strut that is biased to a curved contracted position. The curved struts are bowed contracted struts and S-curved contracted struts. A holding member engages separate portions of the strut to retain the strut in its biased curved contracted position. The contracted strut assemblies are pivotally attached to the anchors and hubs on the surface. The frame assembly is erected by releasing the holding members to allow the strut assemblies to spring to their natural elongated positions.

Abstract: A frame assembly covering an area having expandable struts secured at their ends to connectors. Outer struts are attached to fixed anchors located at the perimeter of the area. The struts have separate members that are moved relative to each other in response to a force, as fluid under pressure or springs, to increase the length of the struts. Contracted struts and connectors are put together on the surface of the area forming a network of struts and connectors. The network may be arranged in regualr geometric patterns. The frame assembly is erected by expanding the struts to raise the network of struts and connectors from the surface of the area. The expanded struts are locked to hold the frame assembly in its erected position.

Abstract: A construction member having a ring-shaped body with an outer edge and an inner edge. The outer edge has a plurality of inwardly directed notches and the inner edge has a plurality of outwardly directed notches. The notches accommodate additional construction members so that two or more construction members can be connected together. The construction members can have the shape of a square, triangle, circle or other multisided shapes.
