This invention relates to polygonal frame structures made from anisotropic materials, and methods for their construction. The polygonal frame structures include at least one frame member that is constructed as a torsion box. The torsion box is constructed with layers of anisotropic materials, resulting in a lightweight, torsionally stiff polygonal frame. Natural and/or man-made anisotropic materials may be used. Wood may be used as a natural anisotropic material. The invention is applicable to bicycles and other vehicles, as well as other products, where frame structures having light weight and torsional stiffness are advantageous.

    Cette invention concerne des structures dencadrement polygonales conçues à partir de matériaux anisotropes et des procédés de construction. Les structures dencadrement polygonales comprennent au moins un élément dencadrement construit en tant que caisson de torsion. Le caisson de torsion est construit avec des couches de matériaux anisotropes, ce qui permet davoir un cadre polygonal léger et résistant aux déformations de torsion. Des matériaux anisotropes naturels ou synthétiques peuvent être utilisés. Du bois peut être utilisé en tant que matériau anisotrope naturel. Linvention sapplique aux bicyclettes et aux autres véhicules ainsi quà dautres produits où des structures dencadrement légères et résistantes aux déformations de torsion sont avantageuses.
