PRIORITY [0001]This application is related to and claims priority from U.S. Provisional Patent Application No. 60/771,718, filed on Feb. 10, 2006, entitled "Collapsible Folding Chair", the entire application being expressly incorporated herein by reference. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002]This invention was not federally sponsored. BACKGROUND OF INVENTION [0003]1. Field of the Invention [0004]The embodiments of the invention relate to portable furniture. More specifically, the embodiments of the present invention relate to portable furniture that is foldable. [0005]2. Description of the Related Art [0006]Furniture is a necessary component of modern living. Items such as sofas, tables, chairs, desks, bookcases, and dressers can be found in almost every home to provide comfort and convenience. Most furniture however, is rather bulky and requires more than one person to transport the furniture item from room to room. To help provide versatility and transportability, certain furniture has been developed that could be folded into compact and readily transportable positions. One type of folding furniture in particular, folding chairs, were developed to allow users to conveniently and comfortably sit or lounge near various locations, such as by the pool or on a lawn, or to quickly and readily increase the seating capacity of a room, by providing a chair that could easily be folded and carried to such a location. [0007]While folding furniture has been useful, many drawbacks presently exist. One drawback relating to foldable furniture is durability. Many items of foldable furniture are not designed for long-term use, but rather are comprised of fabric material that easily wears over time. Additionally, many items of foldable furniture, such as chairs, do not provide designs that allow for stable use of the furniture, but rather opt to provide simple folding and unfolding features that are not designed for optimized support capacity. These chairs can result in a user falling out of the chair as the user attempts to sit down in the chair, possibly leading to serious injury. Another problem with foldable furniture is that it often does not provide for the ability to be used outside one particular setting. For example, beach chairs do not offer the ability to be used, at least fashionably, in a home environment, such as in a guest room or a family room. Therefore, because of the limited purpose of the foldable furniture, a consumer must purchase additional furniture to achieve the desired result, costing additional time, effort, and not to mention money. [0008]A further problem associated with folding furniture is the lack of convenient carrying means. To carry a folding chair, for example, one must generally grasp a leg member, the edge of the seat portion, or carry the whole chair using both hands, which can result in an awkward carrying position for the user. Folding chairs have also presented the problem of not remaining in a compact and folded position during transport. Due to the lack of strong hinge members that can lock a chair into position, combined with the awkward carrying position that users generally have to use when transporting a folding chair, often results in a user being inconvenienced by the chair falling out of the compact and folded position. [0009]Therefore, there is a current need for a chair device that provides for a compact, easily storable and easily transportable device that may be easily unfolded and that that allows the unfolded components to be locked in place to form a stable chair that may not accidentally collapse when a person attempts to sit in the chair. [0010]In this respect, before explaining at least one embodiment of the invention in detail it is to be understood that the embodiments of the invention are not limited in their application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings. The embodiments of the invention are capable of being practiced and carried out in various ways. In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. BRIEF SUMMARY OF THE EMBODIMENTS OF THE INVENTION [0011]The preferred embodiment of the invention provides a collapsible chair device comprising a seat portion, a backrest portion, two or more front leg members, two or more rear leg members, a base portion, and a brace member. The backrest portion is attached to the seat portion and includes a cross-member, with the seat portion being attached to the cross-member by at least one hinge. The backrest portion comprises at least two backrest upright members, a first backrest cross-member, and a second backrest cross-member attached between the at least two backrest upright members. The first backrest cross-member is attached between the backrest upright members on one end of the backrest upright members and the second backrest cross-member is attached between the backrest upright members on the other end of the backrest upright members. The backrest upright members are attached to each of the two or more rear leg members by a hinge. [0012]The two or more front leg members are attached on one end to the seat portion. The front leg members are structurally connected by a front support member. The front leg members are attached on one end to the base portion by a double hinge mechanism to allow the two or more front leg members to both pivot and lift off of the base portion. The double hinge mechanism comprises a mounting bracket having a base portion and a hinge portion coupled to the base portion, the hinge portion perpendicular to the base portion. The hinge portion has a pin accepting portion on the distal end thereof, and a hinge plate pivotally secured to the mounting bracket by a pin, rivet, bolt or other similar attachment mechanism. The hinge plate also contains a first end with a mounting bracket pin receiving portion therein and a second end with a front leg pin receiving portion therein, wherein the pin is disposed through the mounting bracket pin receiving portion and the pin accepting portion to secure the hinge plate to the mounting bracket. Each of the other ends of the front leg members contain a pin receiving portion and a hinge plate slot disposed therein, wherein a front leg pin can be inserted through each of the pin receiving portions to secure the hinge plate to the two or more front leg members and the hinge plate slots can receive the hinge plate to enable the chair to be securely positioned into a fully extended position. [0013]The rear leg members are attached on one end to the backrest portion. The rear leg members are structurally and pivotally connected by a rear support member through a hinge mechanism. The base portion is pivotally attached to the other end of the front leg members and the other end of the rear leg members. The brace member is attached on one end to the front support member by a hinge and attached on the other end to the seat portion by a hinge. The brace member comprises two brace sections attached by a locking hinge. [0014]When in a locked position, the seat portion, backrest portion, front leg members, rear leg members, base portion, and brace member form a stable chair device. Releasing and folding of the brace member causes the pivoting members to pivot and fold in a forward direction until the locking hinges between the rear leg members and backrest portion must be released, thereby allowing the member to continue to collapse forward until the front leg members, seat portion, and backrest portion lie flatly together, such that, with the allowance of the double hinging mechanism, may be folded back over the rear leg members therein forming a compact configuration where the various members lie substantially flat and parallel to the adjoining members. [0015]In another embodiment, the device can also include a backrest portion brace attached to the seat portion. The backrest portion brace includes a first brace member attached on one end to one side of the seat portion, a second brace member attached on one end to another side of the seat portion, and a cross-brace attached on one end to the other end of the first brace member and on the other end to the other end of the second brace member. The backrest portion brace is configured such that when the chair is positioned in the fully extended position--that is, the position in which a person can sit in the chair--the cross-brace is positioned on the side of the backrest portion opposite the seat portion, and connects the two at an approximately 45 degree angle. A brace support is also attached to each of the two backrest upright members for supporting the cross-brace when the chair is positioned in a fully extended position. [0016]In a further embodiment, the device can include a backrest brace pivotally attached to two sides of the seat portion. The backrest brace contains a first brace member attached on one end to one side of the seat portion, a second brace member pivotally attached on one end to the first brace member and attached on the other end to one of the upright members. The backrest portion brace is configured such that when the chair is positioned in the fully extended position the backrest brace is straightened to secure the backrest portion to the seat portion. [0017]While the figures enclosed herein illustrate iterations of the invention teaching a chair which rests on the ground utilizing either the base member or the legs, it is envisioned that the invention could be manufactured utilizing a variety of terminal objects attached to the base member or legs. Such terminal objects could include wheeled casters, pads which can be attached through sticky surfaces or tacks/screws, and other items well known in the art. [0018]There has thus been outlined, rather broadly, features of the embodiments of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the embodiments of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. BRIEF DESCRIPTION OF THE DRAWINGS [0019]The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principals of the embodiments of the invention.
