PURPOSE: An A-frame with a ladder is provided to be easily manufactured and mass-produced due to a simplified structure; to be used in many uses such as a ladder, a chair, and A-frame according to whether foldability is provided or not; and to be easy to carry and keep due to foldability. CONSTITUTION: An A-frame with a ladder comprises a pair of body frames(110), a bed frame(120), and a supporting frame(130). The body frame is formed with a back unit(110a) and a shoulder strap(110b) on the upper part, and fixed by multiple connection pieces(111) which are formed on the lower part of the body frame. The bed frame is connected through a hinge shaft(120a) to one side of the middle part of the body frame so that the bed frame is foldable, and connected with each other with multiple supporting pieces(121) which are formed in the width direction. The supporting frame is combined with the hinge shaft(130a) on the other side of the middle part of the body frame in order to be foldable, and connected with each other by a fixing piece(131) which is formed in the width direction. The supporting frame is formed with a nonslip element(132) which prevents slipping down on the lower end. The hinge shaft is formed with latching support plates(120b,130b) respectively on the lower part and the upper part so that the fixing state, where the bed frame and the supporting frame are fixed with a space from the body frame, is maintained. |
