Prior folding chair mostly consists of seat cushion formed by a wooden-base cushion framed by a closed metal frame. The punched metal seat plate or molded plastic seat plate are also commonly used in folding chairs.
  • However, the closed metal frame around the cushion will confine the design of the seat of the chair, and the punched metal seat will cause higher cost for manufacturing. The molded plastic seat is concerned about its safety and bearing capability, enhancement of thickness and material will oppositely increase the weight and the waste of storage.
  • US 2009/0146467 discloses a chair may include a seat, a chair back and a frame that may be connected to the seat and/or chair back. The chair back and the frame may include engaging portions and/or receiving portions that may be sized and configured to contact, abut, engage and/or interlock with each other to connect the chair back to the frame.
  • Another example of such chair is disclosed in US 2007/0257524 .

    DETAILED DESCRIPTION OF THE IVENTION
  • In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details.
  • Referring to Figs. 1 and 3, two embodiments of convenient telescopic folding chair according to the present invention are illustrated. The embodiments both include front foot 1, back cushion 2, rear foot 3, seat cushion 4, and telescopic rods 5 arranged between two lateral sides of the seat cushion 4 and the two ends of the rear foot 3.
  • Referring to Figs. 1, 2, and 5, the front foot 1 pivots on the rear foot 3 through arranging holes 11. Two retaining holes 12 are formed near to two ends of the front foot 1 respectively for receiving two spring-loaded pins 21 on two lateral sides of the back cushion 2. Two plugs 22 are also formed to the two later sides of the back cushion 2 for being inserted into the two ends of the front foot 1 so that the back cushion 2 is fixed to the front foot 1 with the spring-loaded pins 21 being retained by the two retaining holes 12. Two connecting plates 13 are arranged oppositely to predetermined locations of an inner surface of the front foot 1. The connecting plate 13 has a through hole 131 for assembling the front foot 1 to a frame 41 of the seat cushion 4.
  • Two sleeves 31 are slid into two ends of the rear foot 3 for receiving the two telescopic rods 5. The telescopic rod 5 is fixed to the two lateral sides of the frame 41 of the seat cushion 4. The three connection points of the telescopic rod 5 to the seat cushion 4, the front foot 1 to the seat cushion 4, and the front foot 1 to the rear foot 3 form a triangle so as to provide an ideal support and a strong structure.
  • Referring to Fig. 5, the seat cushion 4 includes a tube frame 41 and a cushion 42. A plug 421 is formed to two lateral sides of the cushion 42 respectively for being inserted into the two ends of the frame 41 so as to form the seat cushion 4. The frame 41 sustains a rear and two lateral sides of the cushion 42 so as to provide a high bearing capability based on the supporting of the front and the rear foot. Without the frame 41, the front side of the cushion 42 can be shaped smoothly or ergonomically as shown in Fig. 7.
  • Referring to Figs. 3, 4, and 6, another embodiment of the present invention is illustrated. The front foot 1 pivots on the rear foot 3 through arranging holes 11. Two retaining holes 12 are formed near to two ends of the front foot 1 for receiving two spring-loaded pins 21 on two lateral sides of the back cushion 2. Two plugs 22 are also formed to the two later sides of the back cushion 2 for being inserted into the two ends of the front foot 1 so that the back cushion 2 is fixed to the front foot 1 with the spring-loaded pins 21 being retained by the two retaining holes 12. Two connecting plates 13 are arranged to predetermined opposite locations of an inner surface of the front foot 1. The connecting plate 13 has a through hole 131 for assembling the front foot 1 to a tube frame 41 of the seat cushion 4.
  • Two sleeves 31 are slid into two ends of the rear foot 3 for receiving the two telescopic rods 5. The telescopic rod 5 is fixed to the two lateral sides of the frame 41 of the seat cushion 4.
  • The seat cushion 4 includes the tube frame 41 and a cushion 42 as shown in Fig. 6. A plug 421 is formed to two lateral sides of the cushion 42 respectively for being inserted into the two ends of the frame 41 so as to form the seat cushion 4. The frame 41 sustains a front and the two lateral sides of the cushion 42 so as to provide a high bearing capability based on the supporting of the front and the rear foot.
  • The present invention is light and space-saving for its thin folded thickness. The ergonomic design will improve the appearance and comfort thereof as well as the quality, practicability, and economic benefit.
