Abstract: A joint system for joining polyhedric facet elements together. Polyhedrons have a plurality of facets. The polyhedric facet elements have facet planes that are generally congruent with the facets of the polyhedrons in which they are found. Various facet elements occupy angular relationships such that they can be joined in rigid stable joints by means of key elements where the planes of the key elements extend generally perpendicular to the planes of each of the facet elements. The joint system is suitable for inter-polyhedron joint systems where the joints include four joint elements, three of which are in the respective polyhedrons that are to be joined, and the fourth is a key element perpendicularly disposed between the other three joint elements.

Abstract: A system for interconnecting construction panels suitable for modular construction has a hybrid connector, a receptor connector and locking connector. The hybrid connector is inserted into the aperture of the receptor connector which limit the displacement relative to each other. The locking connector is inserted into the aperture of the hybrid connector to interlock the three connectors. A panel connector can have an extension tab to provide additional locking action. Panel connectors can have stiffening portions that fill spaces between the connectors to reduce the need to insulate the interconnection and assist in repelling foreign matter entry. A method for interconnecting construction panels includes mating the hybrid connector and the receptor connector and then mating the locking connector from either side of the receptor connector.

Abstract: A structural assembly for building dodecahedral-based structures for habitable or commercial use, or for use as play equipment, models, or toys, is provided. Panels with shapes including hexagonal, rhombic, and trapezoidal are assembled edge-to-edge using ordered edge connections (i.e. alternating connector and receptor edges) to minimize the number of different panels required for producing a complete structure.

Abstract: A teardrop shaped vehicle body which elevates from front to rear thereby providing a safe and aerodynamic shape on which two front wheels and a single rear wheel are rotatably mounted. The vehicle body includes a frame over which flat sheets are bent without substantial plastic deformation and attached thereto to form a skin. The skin contains a transparent portion allowing a driver to view the surrounding terrain, and portions of the skin are detachable from the frame to allow access to the inside of the vehicle body.

Abstract: A Stressed Panel Structure forming checkerboard spheroids and non-checkerboarded conical sections are formed using semi-rigid panels of wood or other materials with generally elongated slots or holes in their corners. Panels are placed corner to corner and a pin or rod is inserted therebetween, becoming stressed when panels are positioned at proper dihedral angles along their axis of intersection. Stressing results generally in bending or other distress of the panel or pin or both.

Abstract: A recumbent bicycle that has a short main frame, a small front wheel, a hub and crank that is in close proximity of the steering tube, and an aesthetically designed and integrally mounted shock absorber seat.

Abstract: Spring plate furniture wherein a planar spring is capable of resiliently supporting loads and/or resiliently being manipulated into a furniture form, the planar spring cut or molded so that usually continuous serpentine members extend between support points at which the cross-section or width of the serpentine members increases when the spring plate is to be subjected to loads and restrained from rotation.

Abstract: A structural system and method which utilizes a plurality of three dimensional nodal connectors and one or more struts extending between and secured to the nodal connectors. Each connector is comprised of at least three relatively flat planar plates and preferably, three pairs of relatively flat planar plates which are assembled in three mutually perpendicular planes in space. Each of these plates in each of the three pairs are substantially similar in both size and shape and are uniquely designed so that they are capable of being interfitted in the mutually perpendicular planes. Also each of the struts are substantially similar in both size and shape and may be connected to the nodal connectors at connection regions which are slightly resilient so that the struts are capable of being snap fitted between such plates of each connector and releaseably retained therein.

Abstract: Interconnecting members are provided for building up geodesic dome-like structures. In a first embodiment, there are provided strut members forming the edges of triangles utilized in the geodesic dome structure and gusset members provided at the vertices of the various formed triangles interconnecting with the ends of the strut members. The ends of the strut members and the gusset members are provided with cooperating integrally formed lip and recess portions arranged to be interlocked together, elastic resiliency of portions of the gusset member being provided to both enable the members to lie at an angle to each other and to be held in their interlocked relationship.
