Abstract: A spherical hauling device for moving foliage and waste. The device includes an operably expandable and collapsible frame generally spherical in shape when in an expanded position, and nearly flat when collapsed. The frame includes a pair of directly opposing hubs having coaxial hub axes of rotation, and a plurality of ribs exiting each hub radially and arching towards the opposing hub. Each hub has at least one track within which the ribs rotate between the expanded and collapsed positions. The device further includes an outer shell spanning the frame for containing the foliage and waste when the device is expanded. The outer shell can include a plurality of panels operably coupled to and extending between adjacent ribs. A yoke is operably coupled to each hub and includes at least one of a shaft and a retractible cord for rolling the device over variable terrain.

Abstract: As with orthotics that are all custom devices molded through a proprietary foam and plaster method and are designed to fit the plantar surface of the foot with full contact, it is necessary to provide a method of applying pressure to the orthotic in a manner that mimics the manner in which a foot applies pressure to it. This is done by applying pressure to a loose fitting diaphragm that is contained within a rigid frame so as to limit expansion of the diaphragm past the boundaries of the device. Further the device contains the diaphragm in such a manner that the diaphragm; 1) Exerts minimal force on the orthotic so as not to bias the deflection of the orthotic by the mechanical pressure of the diaphragm. 2) Uses minimal force to expand the diaphragm so as not to bias the pressure reading indicating how much force is being applied to the orthotic. 3) Closes in such a manner that pushes and holds the orthotic device up against the measuring rod, front window and bottom reference baseplate.
