Abstract: A high strength low density panel. The panel is formed of sections. Each section will preferably have the shape of a cuboid or a prism. At least one face of each section is provided with a buttress. The sections are preferably inverted relative to each other. The sections are configured so that they share sidewalls with each adjacent section, which creates a series of braces extending across the panel. The prismatic sections are paired to form cuboids. These cuboids have a diagonal internal wall. The internal walls of the cuboids align in the panel to create braces that extend across the panel at an angle to the other braces. Finally, all of the buttresses are configured so that the buttress of adjacent and cater-corner sections meet their respective common section corners at substantially the same point.

Abstract: A vertically stabilized shelf bracket assembly having at least two support strips on which a plurality of shelf brackets are mounted. A cover is provided that aesthetically enhances the shelf bracket assembly and stabilizes it at the same time. In one embodiment, the cover includes a cap and a hanging casing. In one embodiment, apertures are provided in the shelf brackets to support a rod. In another embodiment an adjustable mounting slot is provided in the support strips to facilitate their parallel installation.

Abstract: A high strength low density multi-purpose panel. The preferred panel is made of a plurality of sections, organized into rows and columns, and each preferably including two voids. The voids are preferably triangular in cross-section and may be rounded at their apex and corners. Solid strips of material, extending between opposite corners and between the faces of each section, intersect at the center of each face, resulting in an X-shaped cross in each section. Each section is rotated ninety degrees with respect to each adjacent section. Each section shares sides with four adjacent sections and corners with four cater-corned sections. The common sides create perpendicular sets of parallel braces running the panel's length and width. The shared corners align and join the X-shaped cross braces with the X-shaped cross braces of their cater-cornered neighbors, creating diagonal braces that run across the entire panel.

Abstract: A high strength low density multi-purpose panel. The preferred panel is made of a plurality of boxes, organized into rows and columns, and each preferably including four alternately inverted voids. The voids are preferably triangular in cross-section and rounded at their apex and corners. The box sides are preferably four solid panels. Cross panels, extending between opposite corners and between the faces of each box, intersect at each box center, resulting in an X-shaped cross in each box. Each box is rotated ninety degrees with respect to each adjacent box. Each box shares sides with four adjacent boxes and corners with four cater-corned boxes. The common sides create perpendicular sets of parallel braces running the panel's length and width. The shared corners align and join the X-shaped cross panels with the X-shaped cross panels of their cater-cornered neighbors, creating diagonal braces that run across the entire panel.
