Document Type and Number:
Japanese Patent JP6635606
Kind Code:
B2
Abstract:
A frame structure using a tube subjected to bending processing by a pushing bending apparatus is provided to solve the problem of a simple body constituting the small-sized interior space. The frame structure forms a plane of frames by bundling a plurality of tubes or bars, each of which is bent to form a waveform of a constant amplitude around a linear axis in a same plane, to contact maximum amplitude portions of the tubes or bars each other, each maximum amplitude portion being in the same position in the longitudinal direction.
