OPENING ANGLE FIXED BUDDHIST PRIEST'S CHAIR

摘要

PROBLEM TO BE SOLVED: To prevent the opening angle of the legs of a Buddhist priest's chair from being easily changed by an external force.;SOLUTION: A force trying to narrow a gap between a horizontal part 24 of a front leg and a horizontal part 32 of a rear leg does not contain a vector component in the direction trying to move up supporting shafts 55 of a pair of metallic boards 51 and 52 but is generated only by a link mechanism for a pair of the metallic boards 51 and 52 supported by the supporting shafts 55. Thus, a seat part 10 can be prevented from being easily narrowed by the turning loads of a pair of metallic boards 51 and 52 supported by the supporting shafts 55, and a stable standing state can be maintained.;COPYRIGHT: (C)2003,JPO
