Abstract: A frame member fastening device and method of manufacture provides a single configuration fastening device which can be used singly in connection with a frame member, or which can be combined with another identical fastening device to form a fastening device assembly for use with frame members of different internal widths, by interlocking two identical fastening devices in an opposed, base-to-base assembly configuration. The fastening device is manufactured in a progressive metal forming process with successive stages in which the features of the device are formed.

Abstract: A collapsible, foldable support structure and conveyance has a frame assembly with multiple interconnected frame members, junction blocks located at intersecting ends of some of the frame members, and wheels attached to the junction blocks or directly to frame members. Fixtures are attached to or integrally formed with the junction blocks for mounting of wheels or other conveyances or components to the frame assembly. A support structure is attached to the frame assembly to support a load such as a human or cargo or both. In a folded configuration, the frame members are moved into a generally parallel arrangement and the junction blocks and conveyances attached to the junction blocks or frame members are drawn together.

Abstract: A frame member miter guide or brace has first and second legs configured for insertion and engagement with adjoining frame members at a mitered joint, the miter guide having a stop with stop edges which accurately position intersecting walls of the frame members for precise alignment of the mitered joint. Stop edges of the stop correspond with the correct positions of the frame members, so that the members are held in place for final attachment and installation. Positive engagement of edges of the frame member walls with the stop edges insures highly accurate orientation of the mitered joint. A fracture line for welded installation of the frame members, and a leg profile which minimizes damage in handling and installation is also described.
