Title:
FRAME STRUCTURE BODY AND TELESCOPIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/001435
Kind Code:
A1
Abstract:
A frame structure body has a pair of sidewall plates (11) and beam members (12,
12'). The pair of sidewall plates (11) has a substantially rectangular
shape, has bent outer peripheral edges, and arranged facing each other. The beam
members (12, 12') are extended in the direction in which the pair of sidewall
plates (11) faces each other, have a bent shape in a cross-section vertical to
the direction of the extension, and connect the pair of sidewall plates (11) at
at least four corner regions by projection-recess fitting. By this, mechanical
strength, such as buckling strength and bending strength (bending rigidity),
capable of resisting to a vertical load, side load, etc. can be secured with the
structure of the frame structure body simplified and reduced in weight. Accordingly,
a telescopic device formed by placing frame structure bodies (10, 20, 30, 40,
50) in a telescopic manner has high mechanical strength, with the device simplified
in structure and reduced in weight.
