Document Type and Number:
Japanese Patent JPH09503964
Kind Code:
A
Abstract:
A space frame apparatus, and process for constructing same, for use in the construction of various vehicles. The apparatus comprises one or more continuous outer frame members, each fabricated from a single longitudinal extrusion, and one or more cross-members. The extrusions include a predetermined number of slots for operable acceptance of the ends of the corresponding cross-members, as well as a predetermined number of regions softened through a localized heat induction process. The softened regions are bent to varying radii in predetermined directions relative to the profile of a specific vehicle configuration and then allowed to harden back toward their pre-softened hardness. The ends of the cross-members are also softened through a localized heat induction process, and then deformed so as to create a collar and flange portion operably positioned on opposite sides of each respective slot for securely maintaining the cross-members to the one or more continuous outer frame members.
