Description

COMBINATION OF BACKPACK AND SILLO BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION This invention relates to the field of backpacks, and more particularly to backpack and saddle combinations. 2. DESCRIPTION OF THE PRIOR ART There have been numerous attempts to develop an ideal combination of backpack and seat or chair, with varying degrees of success. Some of these prior art devices are described below. The patent of E.U.A. No. 3,307,758 to Platt teaches a carrier bag and back rest device. The Platt device has a rigid frame with flexible portions for the back and thighs, with adjustment cords. Unfolding the device, an adjustable chair backrest is formed, and bending it again forms a basic carrier bag, but without closed sides. When the device is unfolded, the backpack part is in fact lost. The patent of E.U.A. No. 4,530,451 to Harnilton, describes a backpack / beach chair combination, wherein a beach chair part is attached by hooks to the backpack. Its inclined adjustment straps are located behind the back of the chair. During use, the beach chair part is detached from the backpack part. Three patents of E.U.A. Nos. 5,289,958, 5,209,381 and 5,016,792 to Jay, are all directed to a knapsack convertible chair, with a rigid aluminum frame, with a bag portion that engages in a folded frame. The rigid frame is held against the body of the user and is supported on the floor by limbs. The patent of E.U.A. No. 4,487,345 to Pierce et al, teaches a backpack chair that uses a frame assembly that bends to become a chair, connected to a backpack. The frame is not hidden inside the backpack per se, and the system appears to be bulky, heavy and inflexible. The patent of E.U.A. No. 4,720,029 to Varana is discloses a foldable backpack frame, which can be used to support relatively heavy objects. The frame is held against the user's body and is not really integrated into the backpack. The backpack and frame of the patent of E.U.A. No. 4,676,548 to Bradbury have the appearance of a normal field chair and is used against the user's back, much like the Veranakis system. The patent of E.U.A. No. 4,392,598 to Dixon describes a convertible backpack chair with rigid side panels.

The backrest portion of the chair is retained by rails. The Dixon chair is a very rigid system and is conceptually quite different from systems that are relatively soft and flexible. The patent of E.U.A. No. 4,795,068 to Blean, discloses a backpack seat which is a U-shaped bar and which is attached to a metal backpack frame with the shoulder straps wrapped around the frame in the form of U to provide straps on which the user will sit. The Crazy Creek Products, Inc. company, 1401 South Broadway, Red Lodge, Montana, USA, offers numerous styles of portable chairs that have a seat portion and a backrest portion, with some models having extension portions extending from the sides of the seat and backrest portions. Adjustment straps extend from the extension portions in the seat and back portions, and allow the inclined adjustment of the back portion relative to the seat portion. However, the chairs of Crazy Creek Products, Inc. are not fixed to a backpack and have to be carried by folding the seat and backrest portions together, winding them longitudinally (without the extension portions being bent inwards). In this way, as can be seen, although there have been numerous attempts to develop an attractive, light-weight backpack and chair combination that looks quite "normal", these prior art attempts have not succeeded. Therefore, the need for such a combination of backpack and chair remains.

BRIEF DESCRIPTION OF THE INVENTION The invention provides a combination of chair and backpack comprising: a backpack portion adapted to carry articles; a chair back portion located on a rear face of said backpack portion; a seat portion extending from a lower rear region of said backrest portion of the chair; seat wings extending outward from side regions of said seat portion and wings of the chair backrest extending outwardly from side regions of the backrest portion of the chair, said seat wings and backrest wings of the chair they function to effectively extend the seat and chair portions when they are in an open position, said seat wings and wings of the chair backrest being adapted to be bent inwardly and contact the seat and backrest portions of the chair when the chair is in a closed position; and belt means for connecting said backrest portion of the chair and said rear seat portion to allow said backrest portion of the chair and said seat portion to be disposed in a desired degree of reclining relative to each other without affecting the capacity of said portion of backpack to carry articles » BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a rear side perspective view of the backpack and chair combination of the invention being carried by a user.

DETAILED DESCRIPTION OF THE INVENTION With reference to figures 1 and 2, the backpack and chair combination of the invention 10 has shoulder straps 12 to carry it on the back of a user. The backpack portion 14 of the backpack and chair combination 10 is similar to a conventional backpack, but has a backrest and chair seat portion 16. Referring to Figure 3, a seat portion 18 is attached to a backrest portion 20 of the chair along a lower region 22. A pair of retaining straps 24 are fixed in an upper portion 26 of the knapsack portion 14 and are used to hold the seat portion 16 in a closed position against the backrest portion 20 of the chair. The retaining straps may use a hook and loop material 28, such as Sailboat "on its ends, with patches of hook and loop material 30 located on a bottom layer of the material 12 of the seat portion 18. Alternatively , other means may be used to selectively hold the seat portion 18 in its closed closed orientation with the backrest portion 20 of the chair, such as spring closures, loops, closures or other means. Referring again to Figure 1, the backpack 10 is carried with the lower face 32 of the seat portion 18 adjacent to the user's back. The seat portion 18 preferably has an upper layer of material 34 and a lower layer of material 32, with a cushioning material 36 (ie, dense but light weight foam-like material) sandwiched in same. The cushion foam type rubber material is likewise preferably sandwiched in the backrest portion 20 of the chair and in the wings 38 and 44 of the seat and backrest. This cushioning material gives the seat a more even shape and avoids excessive "hammocking" of the device when a user is seated. The upper and lower layers of material 34 and 32 can preferably be coated with nylon, ie Cordura, or it can be canvas, leather or any other durable material, or even a plastic material The cushioning material 36 will not only provide cushioning to the user when he or she is seated, but will also give the seat greater elasticity and provide a more even and smooth shape A pair of seat wings 38 extend outward from the side regions 40 of the seat portion 18. A support 42, which is generally rigid (that is, made of fiberglass, rigid plastic or the like) is positioned within each of the seat wings 38. These wing portions 38 of the seat are bent outwardly from the seat portion 18. when the device 10 is being prepared to be used as a chair The backrest portion 20 of the chair has backrest wings 44 extending outward from later regions 46 of the backrest portion 20 of the chair. A pair of generally rigid supports 48 of the backrest of the chair (i.e., made of fiberglass, rigid plastic or the like) are placed within the wings 44 of the backrest. The wings 38 of the seat and the wings 44 of the backrest can be reinforced, as desired, that is, with a cushioning or extra filling material (not shown) in its upper and lower regions to help prevent the supports 42 from seat and the backrest supports 48 of the chair come out through its wings 38 and 44. The wings 38 of the seat and the wings 44 of the backrest act to effectively extend the seat and back portions 18 and 20, over the normal width "U" of the seat and backrest portions 38 and 20, to a wider "EU" position that results in a wider and more comfortable chair.

Referring to Figures 4, 5 and 7, a pair of flexible belts 50 and 52 with optional adjustment means 54 and 56 are respectively connected to the wings 44 of the chair and to the wings 38 of the seat. To provide additional strength and a lateral support for the backrest of the chair, preferably a trangular extension portion 58 of the back of the chair extends from an upper region of the wing 44 of the back of the chair, and a triangular extension portion 60 of the seat portion extends from a front region of the wing 38 of the seat. The straps 50 and 52 extend from the extension portions 58 and 60. The optional adjustment means 54 and 56 may comprise pairs of rings, snaps and buckles that snap together, or other known means. By adjusting the working length of the belts 50 and / or 52, the relative reclining degree of the backrest portion 20 of the chair with the seat portion 18 can be easily adjusted. The device 10 can also be manufactured with simple belts of a predetermined length without adjustment means, to establish a predetermined degree of recline (not shown). During the use of the device 10, when the user wishes to use the device 10 as a chair, he or she will uncouple the retaining means 24 and drop the seat portion 18 to release the straps 50 and 52 and their adjustment means 54 and 56. The wings 38 of the seat and wings 44 of the backrest of the seat will then be bent outwards to extend the seat and backrest portions 18 and 20 of the chair. Referring to FIGS. 6 and 7, a piece of jacking floor 62 can also be provided. This normally doubles within a pocket or cavity 64 formed between the material layers of the back portion 20 of the chair and a rear face of the backpack 14, and is fixed in the vicinity of its rear region 66, at or near the opening 64 of the bag. Alternatively, the piece of floor cloth 62 can be attached detachably to the remainder of the backpack 14. When the user wishes to sit on a dusty or dirty surface, the piece of jailable floor cloth 62 will be pulled outward so that its leading edge 68 is positioned from the leading edge 70 of the seat portion 18. Complementary hook and loop material patches 72 are used for the hook and loop material patches 30 on the seat portion 18 to detachably detach the piece of floor cloth 62 closely against the seat portion 18. This piece of floor cloth 62 prevents the bottom 32 of the seat portion 18 from getting dirty and then transferring this dirt to the back of the user of the backpack. The piece of cloth for jacking floor 62 is put back into its bag 64 when it is not used. As shown in Figure 8, when the device 10 is placed, the resulting chair seat and backrest will allow the user to sit comfortably anywhere and recharge. Unlike other backpack and seat combinations, the device does not need a heavy or bulky frame, and the device looks substantially normal when carried by a user. The backpack 14 will also not need to be emptied at all when the seat is being used, but it bends outward to be wide and comfortable. The overall result is a comfortable, adjustable, light weight and easy and quick to place and store chair that is available anywhere and anytime. Referring to Figure 9, there is shown an alternative embodiment of a rucksack and saddle 80 of the invention with a removable reclining chair portion 82 (without the shoulder straps of rucksack portion 84 being drawn for purposes of clarity). In this embodiment, instead of being permanently affixed to the rucksack portion 84, the chair portion 82 (with its backrest portions and saddle seat) is fixably deep to the back of the rucksack portion 84. One or more Detachable fixing means are used to achieve this. The removable fastening means may comprise, for example, one or more sections of hook and loop material 86 and 88, snap fasteners 90, straps 92 and loops 94, or a closure 96 positioned around at least a portion of the perimeters 98 and 100 of the portion of backpack 84 and chair portion 82, respectively. An advantage of this modality of the chair backpack and backrest 80 is that a user can temporarily remove the chair portion 84 when he or she is not going to need it, but can quickly refer to it for s? later use. In all other aspects, this embodiment of the backpack and saddle combination 80 is similar to the embodiment shown in Figures 1-8, as described more in detail above. Referring now to Figure 10, a partially open view of the backpack and chair combination 10 and 80 of Figures 1-9 is shown. The knapsack portions 14 and 82 may have incorporated therein an insulated and / or waterproof lower portion 102. This insulated bottom portion 102 may be used to carry foods and beverages that are desired to be kept cold, i.e. packaging for six soft drinks. The lower portion 102 is preferably lined with a waterproof material 104, i.e. vinyl, coated nylon, Mylar *, breathable coated nylon fabrics such as Gortex, and the like.All walls 106 surrounding the lower portion 102 they are also preferably filled with insulating material 108, such as a thin foam rubber, styrofoam, or other known insulating material The lower portion 102 is preferably accessible from an upper portion 110 which is operable by lowering a perimeter closure 112 that connects to the lower portion 102 with an upper portion 114 of the backpack 14? 82. The drawings and the foregoing description are not intended to represent the unique form of the invention in relation to the details of this structure and manner of operation. for a person skilled in the art that modifications and variations can be made without departing from the spirit and scope of the invention. that specific terms have been used, they have a generic and descriptive sense only and not the purpose of limiting the scope of the invention that will be outlined in the following claims.
