Lifting and lowering structure of a long-legged chair

Abstract

A long-legged chair includes a pair of seat supporting members, which are each connected to a respective one of front legs of the chair so as to slide up and down on the front legs; each seat supporting member has a hollow protruding portion thereon, which has a hole facing and adjacent to a corresponding front leg, and which has a button received therein and pivoted thereto; each button has a pressed portion and an inserted portion passed through a corresponding said hole so as to be received in one of the recessed portions in order for the seat supporting members to be firmly held by the front legs; when the buttons are pressed at the pressed portions, the inserted portions will be out of the recessed portions of the front legs, and in turn the seat supporting members are allow to slide on the front legs to adjust height.
