Abstract

A metal extrusion and nodes based structure is provided. The structure comprises one or more arc members connected by one or more node members, wherein the arc comprises (i) a wing feature which is configured to mate with one or more non-structural components, (ii) an internal passage feature which is configured to be inserted into a connecting feature of the corresponding node member, and (iii) one or more keying features formed from a mating interface with the corresponding node member.

First claim

The invention claimed is:

1. A die for deforming a metal extrusion, the die comprising:
a first die component that moves and deforms a first portion of the metal extrusion in a first direction; and
a second die component that moves and deforms a second portion of the metal extrusion in a second direction different than the first direction,
wherein the first die component and the second die component define a shape of a die cross-section of the die, and wherein when the first die component moves in the first direction and the second die component moves in the second direction, causes the shape of the die cross-section of the die to change, and
wherein the first direction is a direction that is transverse to a length of the metal extrusion, and the second direction is a direction of rotation around a direction parallel to a length of an elongated cavity of the metal extrusion.

2. The die of claim 1 , wherein the first and second die components deform the first and second portions of the metal extrusion, respectively, such that a shape of a first cross-section of the metal extrusion at a first location along a length of the metal extrusion is different than a shape of a second cross-section of the metal extrusion at a second location along the length of the metal extrusion.

3. The die of claim 1 , wherein the first die component is arranged in a first layer, and the second die component is arranged in a second layer that overlaps the first layer.
