[0004] 1. Field of the Invention

[0005] The present invention relates to a universal, portable, foldable chair. More specifically, the present invention concerns to a universal heavy duty, light weight, portable, foldable chair which consists of a frame, frame stabilizers, seat, and a locking mechanism to: hold the frame sturdy while in use, keep the chair compacted when in the folded position, and to harness the chair during storage or when being carried.

[0006] 2. Description of the Prior Art

[0007] In many household, commercial, leisure, and military settings it is desirable to have a portable, foldable, heavy duty, light weight chair. It is known in the art to create a chair that can be easily carried and stored. Furthermore it is known that a sturdy comfortable yet compact chair is useful and convenient. Additionally it is known in the art to design a portable chair which is strong enough to hold, for example, at least a 200 pound person. However, these prior art folding chairs are problematic for overweight persons. Further more the prior art is not durable for long time use by overweight or military personal. The reason being these category of people have either a heavy weighing body or are carrying heavy equipment on there clothing in which the chair can not withstand for excessive use and pressure. Additionally prior art foldable portable chairs are relatively bulky and heavy if they are intended for use by a person who is over 200 pounds, requiring undesirable amounts of storage space and/or creating a difficulty when being carried.

[0008] A universal heavy duty, light weight, portable, foldable chair is very useful at home or on trips. In this specification a universal heavy duty, light weight, portable, foldable chair is called “a foldable chair” hereinafter. Some other uses for a foldable chair, but not limited to, are: fishing, camping, sporting events, children gatherings, for emergency personal such as paramedics for people in stress that must sit down, and for army and related fields. A folding chair can also be used as a leg rest or small table. Furthermore, a folding chair so compact can be easily put into a persons pocket or handbag. A foldable chair is usually assembled with a chair frame made of bent steel rods, hinge at the center, cloth frame stabilizers, and a seat cloth thereon. Of course the chair frame can be made of various materials including but not limited to hollow steel rods, plastic hollow and solid rods. The hinge which holds the four piece frame assembly intact and allows for the chair to be folded can be made of hollow steel. Of course the hinge can also be made of plastic hollow or solid as well as a solid piece of steel. The seat cloth and frame stabilizers are made of a woven fabric with sufficient strength. Of course the seat cloth and frame stabilizers can also be made of various materials as well. The locking mechanism can be of any type and material but allow for easy locking and unlocking.

[0009] Conventional folding chairs are not designed to hold as much weight in comparison with its own size and weight as this folding chair can. For example a prototype of this folding chair was tested. The prototype was 11.5 inches high by 11.5 inches long and 6 inches wide, the chair held up a person weighing approximately 400 pounds. This shows the stability and capacity of the chair, even of the small prototype. Furthermore, conventional folding chairs do not fold into such a compact size in comparison with its own size and weight when at the unfolded usable position as this chair does. The proto type mentioned before was also measured when folded. The measurement when folded is as follows: 8 inches by 6 inches by 1 inch. Furthermore the chair can be carried in a persons pocket or handbag with no discomfort or waste of space.

[0010] Accordingly, there exists a need for a universal heavy duty, light weight, portable, foldable chair which can be used conveniently and conventionally. Furthermore, a folding chair which will be easily carried and stored.

[0018] FIG. 1 illustrates a universal heavy duty, light weight, portable, and foldable chair according to the present disclosure comprises a frame 1 comprising four shape supports 11a, 12a, 13a, 14a held together and in position at the center by a hollowed cylinder hinge 15a. The hinge allows the four frame parts to rotate freely when the chair is unlocked and is to be folded or opened, as shown in FIGS. 1–2 and FIG. 6. The seat comprises of two cloth straps 16a and 16b. The seat straps are made of a strong fabric, preferably canvas or oxford cloth. Both ends of the seat straps are folded and connected to itself to form loops 17a, 17b, 17c, 17d where the frame rods 11a and 12a will be received. Cloth straps 18a and 18b are attached to each side of the chair. One end of each strap 18a and 18b is folded and connected to itself to form a loops 19a and 19b where the frame rods 11a and 12a will be received. The other ends of the cloths straps 18a and 18b will be cut straight, as shown in FIG. 5 19c and 19d. At the bottom of the chair, the two frame rods 13a and 14a have indented sections 20a and 20b. A two piece cloth assembly 22a and 22b connects the cloth bands 18a and 18b to 21a and 21b. Cloth band 21a will be connected to the two piece cloth assembly 22a at one end and have a locking mechanism 23a at the other to lock with one end of cloth band 21b. The locking mechanisms should preferably be one which will allow a strong hold when in use yet be easily unlocked to allow for folding of the chair. For examples, a hook and eyelet mechanism can be used. Cloth band 21b will be connected to the two piece cloth assembly 22b at one end and have a corresponding locking mechanism 23b to fit the mechanism 23a at the end of the cloth band 21a.
