Abstract
A support frame device for connecting a seat portion to an upright post includes a base mounting plate with right and left anchoring plates secured to right and left anchored plates of a spacer plate, respectively. An annular stiffening member has an annular abutment end abutting against a lower peripheral edge portion of the spacer plate. A hollow stem with an upper flange portion is extended through a post mounting bore in the spacer plate and an axial passage of the stiffening member such that the flange portion abuts against an upper peripheral edge portion of the spacer plate. An annular lower end of the stem is then malleated to form a flared portion that abuts against a lower end of the stiffening member.
