WORREL a HERZ/G ATTORNEKS United States Patent 2,764,327 CARRYING PACK Roland T. Stevenson, Fresno, Calif. Application October 3, 1952, Serial No. 312,890 14 Claims. (Cl. 224-8) The present invention relates to packs and more particularly to packs of the character adapted to facilitate the carrying of food, clothing, bedding, cooking utensils, camping equipment, fishing equipment and the like by hikers, cyclists, military troops, and others desiring or required to carry loads on their backs.

The carrying of adequate supplies is an onerous task confronted by most campers who participate in hikes and cycling trips. Even though requisite supplies are kept to a minimum their transporting by person is frought with inconvenience and discomfort and is productive of fatigue seriously impairing anticipated pleasure. Although many types of packs have been devised their shortcomings are well-known. Even back-packs developed by careful research, such as those used by ground troops and paratroops to carry necessary paraphernalia, are difficult properly to load, create discomfort to the wearer by pressing against his back unyielding objects of the load, or of the pack structure itself, and do not permit access to articles of the load.

An object of the present invention is to provide an improved back-pack.

Another object is to provide a pack that is light in weight but durable.

Another object is to provide a pack that is made comfortable to wear by the avoidance of engagement of all rigid or unyielding parts thereof against the wearer.

Another object is to provide a pack adapted to support the major portion of its weight and that of its contents on a fabric panel tensioned against the back of a person carrying the pack.

Another object is to provide a pack that is speedy and easy to load with all unyielding objects removed from positions of bodily contact.

Another object is to provide a pack making provision for the expeditious access to all portions of a load contained therein.

Another object is to provide a pack of the character described that is easily disassembled for cleaning and/ or repair purposes.

Further objects are to provide improved elements and arrangements thereof in a pack of the character described that is economical, adapted to production in a wide range of sizes, and that is fully effective in accomplishing its intended functions.

Still further objects and advantages will become ap parent in the subsequent description in the specification.

Referring in greater detail to the drawing:

The pack of the instant invention is indicated as a whole by the numeral 10 in Fig. 4 of the drawing. The

ice

pack 10 is provided with a stave 14 which is an inverted substantially U-shaped member conveniently made of wood. Other materials may be employed to form the stave but it has been determined that wood has the de-.

sired substantial rigidity with adequate resilience. It also is economical and possesses a desired low heat conductivity of advantage in extremely hot or cold climates. The stave is formed from an elongated piece of wood of square or rectangular cross section which is warped to its U-shape to provide an arcuate central portion 15 and a pair of opposite downwardly divergently extended substantially straight legs 16. The legs are preferably disposed in a common plane and diverge to a greater extent prior to mounting of the fabric portion 17 shown in Figs. 1 and 2 thereon. As will subsequently become apparent the fabric portion resiliently compresses the legs toward each other and a portion thereof is held in a taut condition for engagement with the back of a user by the legs.

The pack includes a foldable container indicated at 20 of fabric or other suitable durable and flexible material. The container employs a forward panel 21 which is of regular trapezoidal form having angularly related side edges 22. The side edges are return folded and sewed at 23 to form divergent tubular portions 24. The tubular portions are adapted to receive the legs 16 of the stave 14 with the legs compressed inwardly by the forward panel which is tensioned therebetween. The forward panel is further defined by an upper edge 25 spaced downwardly from the central portion 15 of the stave and a lower edge 26 parallel to the upper edge of the forward panel. The forward panel further provides a forward surface 27 and a rearward surface 28 which are designated for convenience in subsequent reference thereto.

The container 20 extends outwardly from the side edges 22 of the forward panel to provide quadrangular side panels 30 continuous with the tubular portions 24. The side panels have laterally extended side edges 31. Horizontally aligned tie tapes 32 are sewed at their ends along the side edges 31 for the purpose of tying the side edges together with the side panels folded rearwardly and inwardly of the forward panel. Vertically spaced support straps 33 are sewed at their ends to one of the side panels and are adapted to receive the handle of a hand axe or hatchet, not shown, therein. A tie string 34 is sewed between its ends in a position between the support straps 33 which may be tied around the handle of a hatchet in the support straps to preclude inadvertent removal of a hand axe from the straps. A sheet of pocket fabric 35 is sewed, as shown, to the outer face of the opposite side panel from the straps 33 and string 34 to provide multiple pockets 36.

The container 20 is enclosed at its bottom by a bottom panel 40'formed of double thickness sheet material of generally trapezoidal form and has an inner edge 4l'continuous at 42 with the lower edge 26 of the forward panel. The bottom panel is also defined by an extended side edge 43 parallel to the inner edge and angular end edges 44. A substantially square back panel 48 has an inner edge 49 sewed, as at 50, to the extended edge 43 of the bottom panel with the back panel further defined by parallel opposite side edges and an extended edge 52 parallel to its inner edge 49. The back panel is prefer-ably of double thickness to provide an outer pocket member 53. The

side edges 51 of the back panel are sewed together at 54 forming a pocket 55 which is open, as at 5 6, outwardly A' like pair edge of the inner fabric of the back panel. The ties 59 and 60 are adapted to be tied together tomaintain the back panel folded upwardly and rearwardly of the forward panel with packed luggage located in the pocket 55.

The container is fabricated with a top flap 64 which comprises a larger cover portion 65 and a smaller triangular anchoring portion 66. The anchoring portion is sewed at 67 to the rearward surface 28 of the forward panel 21 downwardly from its upper edge 25 with the cover portion extending outwardly from the forward panel and terminating in an extended edge 68. The cover portion of the top flap is bounded by opposite substantially parallel side edges 69. The extended edge 68 of the top flap is return folded against its outer face and terminates substantially midway between the return fold and the upper edge 25 of the forward panel defining a pocket member 70. The pocket member is sewed at 71 to the side edges 69 of the top flap forming a top flap pocket 72. A pair of buckle straps 73 are secured between the double thickness bottom panels 40 in transverse spaced relation by the sewing 50 that attaches the back panel 48 to the bottom panel 40. A buckle 74 is attached to the extended end of each of the buckle straps 73. A pair of closing straps 75 are secured at one of their ends by sewing at 76 to the top flap. With the straps 75 anchored in the buckles 74, the top flap is held in rearwardly and downwardly folded position with the back panel pocket closed thereby.

A substantially rectangular auxiliary panel 80 is defined by an upper edge 81, a lower edge 82 and parallel opposite side edges 83. The upper edge of the auxiliary panel is sewed at 76 to the outer face of the top flap immediately above the top flap pocket 72. The lower edge 82 of the auxiliary panel is return folded rearwardly and upwardly in overlaying relation with the side edges sewed together at 85 forming an auxiliary pocket 86 that is open upwardly immediately below the sewing 76. The upper edge 81 of the auxiliary panel is return folded rearwardly and downwardly forming an auxiliary flap 88 which functions as a closure means for the auxiliary pocket 86. A single buckle strap 89 is secured similarly to the buckle straps 73 midway therebetween with a buckle 90 attached to its terminus. A single outer strap 91 is secured at one of its ends by the sewing 76 at a position midway between the closing straps 75. With the strap 91 attached to the buckle 90, the auxiliary pocket 86 and its auxiliary flap 88 are held inwardly against the top flap pocket 72 as best shown in Fig. of the drawing.

With reference to Figs. 1 and 3, a substantially rectangular reinforcing piece 95 of leather, plastic or fabric is preferably sewed at 96 to the forward surface 27 of the forward panel 21 slightly below the upper edge 25 thereof. A pair of shoulder straps of leather, plastic or fabric having upper ends 98 and lower ends 99 are attached at their upper ends 98 to the forward panel and the reinforcing piece by the sewing 100 at a position midway between the side edges 22 of the forward panel with the shoulder straps extending upward and divergently therefrom. A pair of buckle straps 101 are sewed at 102 against the end edges 44 of the bottom panel extending rearwardly therefrom. A shoulder strap buckle 103 is attached to the terminus of each buckle strap 101. With the lower end 99 of each shoulder strap secured to a respective buckle 103, the shoulder straps may be placed over the shoulders of a person whereby the pack may be conveniently carried.

A pair of optional tie tapes 107 are sewed at 108 to the outer surface of the top flap 64 adjacent to the upper edge of the forward panel. The auxiliary tie tapes are adapted to hold a raincoat or poncho 109 or other article, as illustrated in Fig. 5 in dash lines.

Operation The operation and utility of the pack of the present invention are believed to be apparent from the foregoing description of its construction and are briefly summarized at this point. The legs 16 of the stave are inserted into the tubular side edges 22 of the container 20. This causes a transverse tensioning of the forward panel 21.

The pack may be quickly and easily loaded by placing the forward surface 27 of the forward panel downwardly on a supporting surface, not shown, with the side panels 30, the bottom and back panels 40 and 48, and the top flap 64 projecting outwardly from the forward panel and likewise resting on the supporting surface.

The most bulky articles of clothing, bedding, or other yielding objects to be loaded, not shown, are first placed on the forward panel. The articles thus positioned are preferably of a character constituting padding for other articles to be carried subsequently arranged in the pack. The side panels 30 are thereafter folded inwardly over the bulky articles and the ties 32 secured to hold the articles between the forward panel and the side panels. The back panel 48 is then brought upwardly over the side panels with the bottom panel 49 closing the space between the lower edge 26 of the forward panel and the lower edges of the side panels. The ties 59 and 60 are secured to maintain the back panel in overlaying relation to the side panels. Other articles may be inserted into the pocket 55 with the draw string 58 thereafter drawn and tied to retain the articles.

The top flap 64 is folded downwardly over the back panel 48 and the pocket 55. Other articles, such as items of food, cooking utensils, or the like are inserted intothe top flap pocket 72. The top flap is held downwardly and the top flap pocket is held closed by securing the pair of straps 75 to the buckles 74. Other small articles to be loaded are placed in the auxiliary pocket 86 and the auxiliary flap 88 brought downwardly over its opening. The single outer strap 91 is then secured to the single buckle to hold the auxiliary pocket against the pack and in closed condition.

If a hand axe or hatchet is to be packed, its handle may be inserted downwardly through the support straps 33 and secured against inadvertent removal by tying the tie string 34 around the handle. Other small articles, such as first aid items, may be inserted into the multiple pockets 36 on one of the side panels 30. The pack is thus loaded and a raincoat or the like is rolled and tied on top of the top flap by the auxiliary tie tapes 107, as illustrated in the drawings.

The completely loaded pack is conditioned for manual carrying by attaching the lower ends 99 of the shoulder straps to the shoulder strap buckles 103 With the shoulder straps looped outwardly from the forward panel. The shoulder straps are thereafter fitted over the shoulders of a person with the forward panel against his back. Inasmuch as the forward panel is tensioned by the outward stretching of the legs of the stave, the pack rests comfortably against the back of the wearer with none of the articles of the pack causing discomfort. The stave serves not only to tension the forward panel but the arcuate central portion 15 thereof functions as a convenient carry handle when the pack is not in position on the back of a wearer.-

The pack is conveniently and economically fabricated from economical and readily available materials. The discomforts incident to carrying conventional packs are minimized by the engagement of the pack with a person carrying the pack only by the tensioned panel 20 which, when formed of fabric, conveniently conforms to such a persons back so as to distribute the load of the pack substantially evenly. The pack is conveniently and easily loaded and unloaded. The slidable association of the legs 16 of the stave 14 in the tubular side edges 24 of the container permits the convenient disassociation of the stave and container for cleaning and repair purposes.
