Description: TITLE: CHAIR PACK BACKGROUND OF THE INVENTION This application for a utility patent follows a previously filed United States Utility Patent having the application serial number 08/812, 108 and a filing date of March 5, 1997. FIELD OF THE INVENTION: This invention relates to a sitting & lounge chair. Specifically, this invention relates to a light-weight durable adjustable chair that can quickly & easily be converted into a portable backpack for transporting itself and additional amenities to any destination. DESCRIPTION OF RELATED ART: There are many types of chairs & backpacks available and common to the marketplace. There are indoor and outdoor chairs of many different shapes and sizes. Many chairs are permanent, others either movable or portable. Some portable chairs can be folded into sections to ease in transporting and storage. Some packs available are for day-use, others for hiking & camping. Both portable chairs and packs are transported and used together by consumers everyday for many different reasons to many destinations. Transportation of folding portable chairs currently on the market has caused individuals many problems. First, these chairs are cumbersome to carry and difficult to hold. One difficulty lies in the unbalanced weight of the chair when it is in the folded position. Another difficulty arises when the chair is folded; the back support and leg support of the chair tend to open when carried in the unfolded position posing a dangerous situation. Further disadvantages of prior art are encountered when people desire to go places where it's necessary to bring other articles in addition to a chair. For example, when one goes to outdoor events, one often desires to bring additional amenities such as a picnic blanket, a beach towel, radio, sun tan lotion, money, edibles and drinks. It is very difficult for one to carry all of these amenities while also carrying a chair. At best, both hands are utilized in carrying such items leaving the holder vulnerable should they require the emergency use of one or both arms or hands to aid a child and at worst, many of these items are dropped by the holder simply because they are too numerous for one person to carry. Inventors have created several types of portable chair and tote-bags to try to solve this problem. The primary piece of prior art, U.S. patent 4,773,574 to Burgard (1988), discloses a pack having first and second rectangular frames which are pivotally interconnected to form a chair which folds into a backpack. This invention is superior to the previous prior art, but it suffers from several serious disadvantages. First, the pack portion is located on the underside of the seat rather than the back of the chair. Second, the support legs are all of the same length, causing the chair to lack the stability achieved in the present invention. Third, this patent describes what is essentially a two-frame structure which does not fold or lock satisfactorily. Other prior art inventions include the following: U.S. patent 4,687,248 to Ross and Friedman (1987) discloses a complex construction and cumbersome process to achieve this. This patent shows a tote-bag that transforms into a chair by a slow complex step-by-step process. U.S. patent 4,190,918 to Glenn M Harvell (1978) disclose only a simple carry suitcase cushion that folds out into a double cushion. This invention does not allow any amenities to be transported inside and only provides a cushion that must be used atop of an existing chair or bench. US Patent 2,915,154 to L.A. Holder (1958) once again, when his invention is converted from a carrying case to a chair all amenities that are being transported inside the carry case must be forfeited for the chair & at worst, this could result in damage or loss to amenities. US Patent 4,676,548 to Patrick H. Bradbury (1987) discloses a bulky & uncomfortable invention. It is basically a lawn chair with a pack on the back which is a good idea but this type of chair is uncomfortable when worn on a persons back. The hard legs against a persons back for any period of time would cause chaffing and bruising at best. The armrests sticking out independently offer a dangerous situation when it is being worn by a person to anybody they may come in contact with. The constraining straps that hold the device in pack formation take much longer to latch and unlatch when converting it back & forth from a pack to a chair. It allows only one sitting level that is low to the ground and offers no lounging position. It is a much more complicated, uncomfortable, bulky, dangerous and limited device compared to the present invention. The prior art teaches various combinations of chairs and backpacks. However, the prior art does not teach a Chair Pack which is as safe, easy to use, and convenient. The present invention fulfills these needs and provides further related advantages as described in the following summary. SUMMARY OF THE INVENTION The present invention teaches certain benefits in construction and use which give rise to the objectives described below. The present invention provides a combination chair and backpack having a pair of seat support frames hingably joined for rotating the seat support frames between a first mutually aligned position for carrying the combination, and a second spread apart position for sitting. The combination further includes a seat means joining the pair of seat support frames and providing an upwardly facing surface when the seat support frames are in the second spread apart position, whereby the support frames are self supporting on a support surface for placing the sitting means at a convenient height. A back support frame is hingably joined to one of the pair of seat support frames and rotatable between an upwardly extending position for establishing a back rest, and a laid-over position wherein the back support frame abuts the sitting means. Attached to this frame is a back pack removably joined to the back support frame. A shoulder mounting means is attached to the pair of seat support frames such that with the pair of set support frames placed into the mutually aligned position, and with the back support frame placed into the laid-over position, the combination is mountable onto a person's back for carrying thereon. A primary objective of the present invention is to provide a combination chair and backpack having advantages not taught by the prior art. Another objective is to provide a combination chair and backpack in which the backpack is mounted on the back of the chair when the chair is unfolded. Prior art inventions mount the pack in inaccessible locations such as the underside of the seat. Placing the pack on the back of the seat is preferably because it places the backpack in a more accessible position. It also allows for a much larger backpack because it is not limited to he space between the legs of the chair. The reason this configuration has not been used before is because the backpack would normally tend to fall over if there is nobody sitting in the chair. It also makes folding the rest of the frame very difficult. These practical difficulties have been overcome with innovations in the frame, as described in the following detailed description of the preferred embodiments. Another objective is to provide a chair on which the support legs of the rear leg frame are longer than the support arms of the front leg frame. This structural feature allows the chair to remain upright when the pack is full and nobody is sitting in the chair. In the prior art, if the pack is located on the back of the chair and the pack is full, the chair tends to fall over backwards. By shifting the center of gravity of the chair, this invention provides a stable chair which will not fall over. Another objective is to provide a three-frame foldable structure which folds with unprecedented ease into a compact final structure. While previous inventions have only allowed very simple, linear folding, this invention calls for first folding the legs, then flipping both legs upside down to fold against the back of the chair. With one sweep of the hand the user can swing the back leg frame over 180 degrees to the backrest frame, automatically folding the front leg frame into a single compact backpack with no protruding parts. Since all three frames are rotatably connected, it is not necessary to add or remove any CLEVIS™ pins to fold or unfold the invention. To achieve this configuration, many important innovations were made. First of all, this invention is made of three rectangular frames which are all readily foldable, rather than two frames and a U-shaped element fixedly attached to the first leg frame. While the Burgard patent calls for attaching U-shaped chair back with two CLEVIS™ pins (causing the frame to protrude awkwardly upwards), this invention uses a rectangular chair back with a "lower portion" which has a "horizontal portion" and rotatably connected with only one CLEVIS™ pin. This unique rotatable connection which is braced against the "horizontal portion" allows total collapse of the chair frame without having to remove a CLEVIS™ pin. This allows the two frames which form the legs fold together and then flip 180 degrees to fit against the frame which forms the back of the chair. This critical innovation is what enables instant and total collapse of the chair frame without having to remove any CLEVIS™ pins. A further objective is to provide a combination chair and backpack which can be securely locked into place with no loose frames swinging around. While the prior art generally has no means to fasten the frames into a secure formation, the present invention locks into a single solid configuration when folded into a backpack, allowing easy transport and use of the invention without fear of invention unfolding. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

The nylon straps are connected by a plastic parachute clip or similar clip which allows the straps to be easily separated. The shoulder cushion 34 is preferably made of a soft durable material such as polyurethane. The shoulder cushion 34 is preferably mounted or molded around the pair of support legs 20b and 20d. Alternative methods are well known in the art and within the scope of this invention. The specific structure and placement of the shoulder cushion 34 is not critical to the inventive nature of this invention, and any number of comparable structures can be designed by those skilled in the art. Comfort cushions like these may be used in any area of the Chair Pack as to supply comfort to the user. Chair Pack in pack formation 1, as shown in Fig. 1A and IB, is worn on the back of a person and is securely held there by a shoulder pads 22 while a rear support cushion 48 wrapped around the bottom member 16e rests comfortably against the user's lower back. For further comfort when wearing the Chair Pack on one's back, the invention preferably includes a shoulder cushion 34. The shoulder cushion 34 is preferably made of a soft durable material such as polyurethane. The shoulder cushion 34 is preferably mounted or molded around the pair of support legs 20b and 20d. Alternative methods are well known in the art and within the scope of this invention. The specific structure and placement of the shoulder cushion 34 is not critical to the inventive nature of this invention, and any number of comparable structures can be designed by those skilled in the art. Comfort cushions like these may be used in any area of the Chair Pack as to supply comfort to the user. Chair Pack in the chair formation 2. as shown in Fig. 2A, 2B, and 2C, is designed to comfortably support the user. Chair backing 42 is preferably a sheet of flexible and inelastic material such as nylon which covers the upper portion of the back support frame 16 to support the user's back while sitting in the Chair Pack. First and second rear support cushions 28 and 48, which are preferably made of a polysynthetic or durable lightweight material. The first rear support cushions 28 are connected to the back support frame 16, preferably wrapped around the parallel side legs 16b and 16h. The second rear support cushion 48 is attached to the top member 16a. The Chair Pack is taken off the back by pulling shoulder pads 22 off the shoulders and holding the Chair Pack in one hand. The user then unlatches the parachute clip and strap 21 with his free hand and the Chair Pack opens and unfolds. As shown in Fig. 2C, the rear leg frame means 20 and the front leg frame means 18 both unfold along a first folding line FI until the front leg frame means 18 contacts the bottom cross bar means 20c. The user can then continue to rotate the rear leg frame means 20 along a second folding line F2 until the seat means 24 stops the rotation of the rear leg frame means 20. In this position, the Chair Pack is in its chair formation 2 and ready for a person to sit in the Chair Pack. As a person sits in the chair portion of the Chair Pack, seat means 24 resists and transfers most of the weight through front and rear-leg support frames 18 and 20. Once the Chair Pack has served its purpose as a chair, the next steps are taken to convert it back into a pack for transportation. The Chair Pack is picked up with one hand by the loop strap handle 12. Gravity causes the rear leg frame means 20 to fold along a second folding line F2. The user then rotates both the front leg frame means 18 and the rear leg frame means 20 along a second folding line F2 until they rest against the back support frame 16. Once this is accomplished reconnection of the parachute clip and strap 21 will secure the Chair Pack in pack formation 1. To place the Chair Pack on the back again simply pick it up by loop strap handle 12, position over your back to allow the free hand to go through a shoulder pad 22, switch hands holding loop strap handle 12 and feed the other arm through the remaining shoulder pad 22. Adjust for optimum fit to travel to the next destination. As shown in Fig. 2A and 2C, the angle of the back support frame 16 of the Chair Pack in chair formation 2 is adjustable. If the next lower level is desired simply push back & up then pull forward on the seat adjustment bar 50 with one hand, while holding front-leg support frame bar 18a with the other hand. Slide the seat adjustment bar in its guide-groove to the next notch (not shown). Each transcending adjustment notch lowers the seat and the back of the chair an increment at a time to allow variations in reclining. As transcending adjustments are induced changes occur respectively between displayed chair seat 24, adjustment bar 50 and height h. Adjustment bar 50 moves up towards rear-leg support frame bar 20a in a notch and slide groove system allowing chair seat 24 to span a greater distance between rear-leg support frame bar 20a and front-leg support frame bar 18a. Once again, the specific embodiment of the adjustment means is not critical to the inventive nature of this invention. Those skilled in the art can devise countless alternative embodiments which are equivalent to the adjustment bar 50 which do not deviate from the inventive nature of the invention. As shown in Fig. IB, some support embodiments of the Chair Pack improve the performance of the Chair Pack. A crossing back strap support system 54 is attached to the rear-leg support frame 20 providing support to a persons back as the Chair Pack is being worn. A second support feature is a crossing back strap support 56 is attached to the back support frame 16 for added back support when a person leans back in the Chair Pack in chair formation 2. Those skilled in the art can devise countless alternative embodiments which are equivalent to these support systems in the same or other areas without deviating from the inventive nature of this invention. While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
