Abstract:
An improved folding chair comprises two side frames each having a front leg, a rear leg, and a linkage bar bridged the front leg and the rear leg, and a first loading bracket and a second loading bracket. The linkage bars are coupled respectively with a tubular rod which is turnable on the linkage bar. The tubular rods respectively attach to a first and a second toggle bar which are pivotally engaged on a toggle joint. The first and the second loading bracket have respectively a first side bar and a second side bar which are pivotally engaged with the first and the second toggle bar in a cross and staggered manner. The first and the second side bar have respectively one end engaged with each other on another toggle joint, and connect respectively a first loading bar and a second loading bar to form a seating zone. The two side frames may be moved towards each other by an external force such that the two tubular rods are turned on the two linkage bars, and drive the first and the second toggle bar and the first and second loading bracket toward each other about the toggle joints which function as fulcrums to juxtapose and fold the chair in a compact size.
