ABSTRACT:
A folding lounge chair has a seat frame, including a front leg and a rear leg crossing each other and hinged to the seat frame. At the crossing of the front leg and the rear leg, a hinge plate having a guide groove is fixed to the rear leg. At two ends of the guide groove are, respectively, upper and lower arrest units. The lower arrest unit is curved upwards. At one end of the lower arrest unit is provided a projected retaining part. One end of a bolt is fixed onto the rear leg, the other end running through the guide groove of the hinge plate, permitting the bolt to glide up and down along the guide groove. Besides allowing the lounge chair to retain a simplified construction, when the legs are unfolded, the bolt will not glide into the lower arrest unit and will be arrested by the projected retaining part. Therefore, the legs will not easily fold up. By lightly patting on the rear leg, the bolt will jump away from the projected retaining part and escape out of the lower arrest unit, and allow the legs to be folded up. Thereby, the legs of the chair can be easily folded or unfolded by simple operation.
