Benefits of technology

[0011] It has been recognized that it would be advantageous to develop a three-dimensional structure or panel with a flatter and thinner configuration, and with enhanced stiffness and strength.

Problems solved by technology

Traditional structural designs have been limited to one or two-dimensional analysis resisting a single load type.
Three-dimensional analysis is difficult because of the difficulty in conceptualizing and calculating three-dimensional loads and structures.
Such truss or pole configurations, however, can be difficult to use in other configurations due to the generally round configuration.

Embodiment Construction

[0040] Reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Alterations and further modifications of the inventive features illustrated herein, and additional applications of the principles of the inventions as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.

[0041] Some aspects of three-dimensional structures are described in U.S. Pat. No. 5,921,048, issued Jul. 13, 1999, which is herein incorporated by reference. As illustrated in FIGS. 1a-f, a three-dimensional grid structure or panel, indicated generally at 10, in accordance with the present invention is shown. As described above, other truss or pole structures have been developed that have generally tubular or ...

Abstract

A three-dimensional grid panel (10) includes an intermediate grid (28) disposed between and attaching two spaced-apart grids (24, 26). Each of the two spaced-apart grids includes a first plurality of elongated components (30, 40), and a second plurality of elongated components (32, 42) oriented transverse to the first plurality of components and intersecting the first plurality of components at nodes. The intermediate grid includes a first plurality of intermediate components (46), each extending between nodes of the two spaced-apart grids, and a second plurality of intermediate components (48), each extending between nodes of the two spaced-apart grids, and oriented transverse to the first plurality of intermediate components.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to a three-dimensional grid structure or panel. More particularly, the present invention relates to a grid structure or panel with enhanced stiffness and / or strength. [0003] 2. Related Art [0004] The pursuit of structurally efficient structures in the civil, mechanical, aerospace and sports arenas is an ongoing quest. An efficient truss structure is one that has a high strength to weight ratio and / or a high stiffness to weight ratio. An efficient truss structure can also be described as one that is relatively inexpensive, easy to fabricate and assemble, and does not waste material. [0005] Trusses are typically stationary, fully constrained structures designed to support loads. They consist of straight members connected at joints at the end of each member. The members are two-force members with forces directed along the member. Two-force members can only produce axial forces su...
