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.
Claims6
A frame structure forming a surface, the frame structure comprising:
- a plurality of elongated members, wherein,
- each of the elongated members have a waveform shape of a constant amplitude about a linear axis,
- each of the elongated members are bundled with another of the elongated members at a maximum and minimum of the waveforms of the bundled elongated members,
- a plurality of the bundled maximum and minimums are on a line perpendicular with each linear axis, and
- the plurality of elongated members include,
- first elongated members bent along a first plane wave about a first linear axis and bent along a second plane wave about a second linear axis perpendicular to a bending direction of the first plane wave, and
- second elongated members bent along a second plane wave symmetrical to the first plane wave with regard to the first linear axis and bent along a third plane wave about a third linear axis perpendicular to a bending direction of the first plane wave, wherein one the first elongated members is faced, contacted, and coupled with one of the second elongated members at a maximum and minimum of the waveforms of the first and second elongated members.
