SHEET 3 OF A INVENTOR. RUSSELL H. ROMNEY BY am ATTORNEY BACK PACK CARRIER SYSTEM The present application is a continuation-in-part of my application Ser. No. 750,521, filed Aug. 6, 1968, now abandoned.
BACKGROUND AND PRIOR ART In US Pat. Nos. 3,225,985, 3,265,260 and 3,490,063, the present inventor has described pack carriers suitable for use by hikers, hunters and other outdoors men, scouts, soldiers, etc. for carrying various goods and loads on their backs. The carrier frames therein described are made up mainly of tubular upright and transverse elements, suitably secured together by pins and other fastenings. They have desirable features of light weight and adequate strength, but they have certain deficiencies, particularly in comfort to the wearer and adaptability to various loads and uses, which the present invention is designed to overcome.
U.S. Pat No. 3,265,260 describes a load supporting bracket or shelf in connection with a pack frame, which is a useful component in the present invention. There is a need, however, for various features of versatility in pack carrying equipment which have not hitherto been available and which the present invention is designed to provide.
With increased leisure time available to many people, and with improved access to woods, mountains and other resorts of nature, there has been in recent years a large increase in camping, fishing, hunting, mountain climbing, skiing and other outdoor activities. These have led in turn to increased demands for better camping and hiking equipment, particularly for load carrying equipment adapted to be used where self powered vehicles cannot go. Along with improved pack frames have come light weight sleeping bags, tentage and other camping gear, and many other items that are desirable for use in areas where all equipment must be man carried. Many of these items can be simply strapped onto a frame, in which case, the design of the frame and its comfortable carriage by the wearer is a most important consideration. Many other items, however, must be carried in such a way as to protect them from the weather and from other sources of damage. While numerous types of bags and the like are available for the latter purpose, they often are not particularly suitable or adaptable for carriage on a back pack carrier frame. They can, of course, be strapped onto almost any frame by using a sufficient quantity of lashing, but this may be very inconvenient.
Aside from the above, the hiker or camper may have several and diverse objects on his trip. He may want to hike to a camp or operating base from which he may want to take side trips while more lightly loaded. He needs carrying equipment that can permit him to deposit part of the load at the base and to proceed elsewhere with preselected items, without having to unpack and reload before he can go For for this purpose the present invention provides multiple bags or containers of weatherproof character, which can be loaded and unloaded independently, and which can be carried with safety and convenience at various positions on the carrier frame.
The prior art is familiar with numerous types of pack outfits which include multiple bags and other containers. Most of these, however, are not conveniently attachable to pack frames and, particularly, are not designed for attachment at various heights or positions on a given pack frame. While it is possible to attach in some way almost any item to almost any kind of pack frame, it is obviously desirable to be able to do so with convenience and efficiency. For the comfort of the wearer, pack carrying equipment must be placed as nearly as practicable to his center of gravity or in a vertical line above it. For this reason, the present invention is designed to permit placement of the load substantially on or above the shoulders of the wearer or as near thereto as possible to insure his comfort and avoid unnecessary fatigue.
' The equipment of the present system is designed for maximum versatility in packing, comfort in carrying, and convenience in loading and unloading. The use of simple but effective lashing to hold all parts of the load in place is facilitated, since the-pack frame itself, and the carrier bag units, are equipped with effective lash retaining or receiving elements of the utmost simplicity. The equipment of this in 'vention includes special loops or pockets for carrying long items, such as tent poles, fishing rods, etc., with a minimum of interference with the wearer or with other articles that normally must be carried. The bags, two or more in number, as desired, which can be referred to collectively as a Stackpac" can be placed above or below each other, and can be secured independently to the frame in a minimum of time and with good security.

DESCRIPTION OF PREFERRED EMBODIMENT Referring first to FIGS. 1, 2 and 3, the basic pack carrier frame will be described. It consists of side frame members 11 and 13, usually more or less vertically oriented, and transverse members I5, 17, I9 and 21. These members are all made of light tubular metal, such as aluminum or magnesium, or of alloys of similar lightness and strength. The transverse members are smaller in diameter than the vertical side members and are passed through them in openings provided for the purpose. Pins 22 and 24 are provided to hold the parts together. Each of the tubular transverse members 15, 17, etc. terminates at each end in a plug element 25 preferably made of hard and durable plastic material, such as nylon, Delrin or the like. In some cases, wood or other material may be used. Plug 25 is provided with a slot 29 across the head 27 to receive and hold in place a lashing as will be described further below. The usual lashing is of a well known type, preferably a braided rope of nylon, polypropylene or other strong fibrous material. The ends of the cross members 15, 17, etc. project far enough outside the vertical members 11, 13 that they can be used to retain one or more turns of lashing between the side frame members and the heads 27. See, for example, FIG. 19. The top transverse or cross member 15 is preferably straight; the others are offset rearwardly in the middle, as shown in connection with member 17, FIG. 3, at 30, in order to conform fairly closely to the body of the wearer. This facilitates carrying the load as near the center of gravity of the wearer or as closely to his body as possible.
Side frame members-ll and 13 are bent forwardly and inwardly toward each other at the top as at 31 and are bent rearwardly and outwardly away from each other at the bottom as at 32 to better conform to the body of the average wearer. Also, for still greater versatility, extension elements 40 may be added at the top to lengthen the side frame members. See FIG. 2. These can be added, for example, to lengthen the frame for an unusually tall person, or for any other purpose. The normal end cap or plug 51, which is normally inserted in the upper end of each of the side frame members is retained there by a spring pin 52, which remains in place by friction. Plug 51 can be taken out by removing this pin and the extension part 40 can be inserted in its place. The plug or cap member 51 can then be placed in the end of the extension 40 and secured then by a pin 52. Each cap or plug member 51 has a cross slot 57 to receive and retain a lashing. Also, a cup or cavity inside each plug 25 is large enough to receive a lashing knot. Similar plug or cap members 51 are inserted in the bottom ends of the side frame members 11, 13 and retained there by pins 53, similar to pins 52. These have similar lash holding notches or slots 57 as shown also in FIGS. 14, 16 and 17. They also may contain a cavity large enough to receive and hold a knot in a lashing.
Intermediate vertical bars or rods 60, 61 are mounted in openings in cross members 17 and 19 and their upper ends are inserted in openings in the lower side of the top transverse member 15. Likewise, their lower ends are inserted into openings in the top side of the bottom member 21. A pivoted shelf member 70, described in greater detail in U.S. Pat. No. 3,265,260, is attached to one of the cross members, such as member 17 in FIGS. 1 and 2. More than one such shelf may be used, as pointed out below. The manner in which the vertical rods or bars are attached to the top cross member 15 will be described in detail in connection with FIGS. 4, and 6, below.
Body contacting webs or broad straps are provided in pairs as shown at 81, 82 towards the top of FIG. 1 and 83, 84 near the bottom of said figure. These are provided with grommets 85 through which a single lashing 87 for the upper pair and another single lashing 88 for the lower pair are provided. By trying these lashings 87 and 88 with proper tension, the weight of the pack and its load bring the pack and particularly the webs 81, 82, etc. into smooth but firm contact with the body of the person carrying the pack. Since the single lashing 87 is shared by each of the body webs or straps 81, 82, etc., these straps are self-adjusting to the body of the wearer. At the same time, by straddling the ends ofa transverse member such as or 17, etc., or 21, the pair of webs, as a unit, cannot shift or migrate up or down the side members 11, 13. This has been a deficiency in prior art webbing arrangements. Also, in the past where such webs have been used, they have usually been wider and fewer in number; the webs of the present invention are relatively narrow. Consequently, they allow freer evaporation of perspiration than wider belts when carried in hot weather. Because of their greater total number, they distribute the load or pressure against the wearers back much better than most of the prior art arrangements.
Shoulder straps 90 and 91 are attached by means of key ring type fasteners (multiple turn spiral rings of spring metal) 92 which pass through the lower ends of the straps, preferably through grommets 93, and through openings in the side frame members near their bottom ends. The upper ends of these straps are secured in the manner shown in FIGS. 4, 5 and 6 by grommets 94 in the straps through which are passed plastic (nylon, Delrin or other strong elastic plastic material) connectors 95 having an upper loop element 96 which surrounds the top cross member 15 and bifurcate legs 97, 98 which pass through the grommets 94 and are held against spreading apart by a retaining ring or ferrule 99. A suitable pin, such as a cowl pin 100 of well known type, is passed through the ferrule 99, through notches between the legs 97 and 98, and through an opening in the vertical rod 60 or 61. This fastening thus holds the vertical rods 60, 61 in connection with the transverse member 15 but also holds the shoulder straps at their upper ends. The connectors are flexible enough that their legs or bifurcations 97, 98 can be spread apart far enough that the connector can be placed astride and over the member 15, or any of the transverse members l7, 19, or 21. When the legs are forced tightly together and retained in such a position by the ferrule or ring 99, the pin 100 cannot be pulled downwardly between them by any reasonable force. The connecting means 95 per se form no part of the present invention, being claimed in a separate application filed herewith, Ser. No. 15,785.
Connecting means for holding the shelf member 70 to the cross member 17, to which it is shown pivotally attached in FIG. 1, are of the same type as just described. FIGS. 7 and 8 show the loop part 101 of such a connecting member 102 surrounding the cross member 17 with its legs inserted in the tubular element 104 which supports and forms a part of shelf member 70. Here again the weight of the dependent shelf 70 is supported by a pin, shown of the cowl type at 105, which passes through the member 104 and in notches between the legs of member 102. One reason for inserting the pin in this manner is that this places the pin parallel with the back of the pack wearer and has no points projecting towards him or into the load. Another reason is that the assembly and disassembly of the parts, or removal of the shelf to another cross member, or from the pack frame completely, is thus facilitated.
FIG. 9 shows in larger scale the manner of fastening the transverse bars to the main uprights 11 or 13. The plastic plug members 25 having an enlarged head 27 and formed of tough strong material such as plastic nylon or Delrin, or the like, all fit neatly in the hollow cross members 15, etc., and are pinned in each case to both the cross member and upright by a pin 111. Head 27 is slotted at 29 to receive a lashing L and is set out far enough from the side of the main upright 11 that such a lashing may be looped around it a time or two to make a secure fastening. The knot-receiving opening mentioned above is shown at 112.
FIG. 10 shows a quadline arrangement for securing a bag or package to the pack frame F. As shown in FIG. 12, two lash lines or small ropes of the type mentioned above are fastened together, in a square knot, for example, so that four lines 116, 117, 118, and 119 can be led off in four different directions. The ends of these lines are each secured to fastenings such as shown in FIG. 9. In some cases they may be secured to the end plugs or caps 51 in the manner already described. Such a cap is shown in FIG. 11 as secured by a pin 52 to upright member 13 and the knot-receiving opening or cavity 54 is plainly visible. FIG. 13 shows a cross section Each plug 51 has a shank 55 reduced in diameter enough to fit neatly inside the tubular member 11 or 13 as shown in FIG. 13. Each plug has also reinforcing internal rib elements 58 at the sides of the cavity 54 to strengthen the side walls so as to give them sufficient strength to support the load while resting on the ground or while resting against lateral supports and also to sustain the pull of tight lashings which may be secured to them.
Turning now to FIGS. 14 to 19, inclusive, these show in various modifications the Stackpac or bag pack arrangement which constitutes an important feature of the whole system. The pack frame F is of the construction described above; one of its side members 11 is plainly visible in FIG. 14; the lower end of the other member 13, is visible also. The assembly shown in FIG. 14 comprises an upper bag "1 and a lower bag 2. Bag 1 is made of weatherproof textile material, formed with side walls 201, 202, 203, etc., a bottom wall 205 and a cover flap 206. The latter has fastening strings 207 and 208 secured in grommets 209 and these are adapted to be tied into D-rings 210 in loops 211 sewed to the rear wall 202. A pocket 215 is sewed onto the cover flap to carry small articles; side pockets 216 and 217 are sewed on side wall 201 in similar fashion and additional pockets not shown may be provided on the opposite wall. In addition, a wide loop or tunnel element 219 is provided along the front edge of side wall 201 to receive a long slender article such as a tent pole, fishing rod or the like indicated at 220. A cooperating slender pocket with a bottom is shown at 221 on the lower bag 2. Together these loop and pocket elements 219, 221 give full support to article 220. By these aligned and cooperating loop and pocket means, a longer slender article can be more stably carried than would be possible with a single loop on a single bag.
The upper bag 1 is provided with side flaps on the front edge of each side wall as shown at 225. The side flaps terminate at the top in an inverted pocket 226, which is adapted to receive the upper end of a main side frame member 11 or 13. Each flap 225 is provided with a plurality of grommets 227 through which lashings L may be passed to secure the flaps 225 to pack frame. These grommets are preferably positioned so that the lashings L may be secured to and around the ends of the transverse members 15, 17, or 19, etc., or around and to the projecting plug members 25, 27. See FIG. 9. Since the transverse members 15, 17, 19 and 21 on the pack frame proper are preferably spaced at equal intervals, or substantially so, the bag "1 can be secured at different levels if desired, except that the inverted pockets 226 might not then fit over the upper ends of the side frame members. It is not always essential, of course, that pocket 226 be engaged with these.
The lower bag "2 is of generally similar construction to bag 1, being provided with a side pocket 230, a rear pocket 231 and other pockets not shown, as desired. The pocket 221 for the long slender article 220 has been mentioned above; similar pocket and loop means for another long article such as 220 may be provided on the opposite side 203 of the bags 1 and "2 if desired. Bag "2 also has frame-engaging side flaps 235 equipped with grommets 236 through which the lashings L may be passed to secure the bag to the pack frame. Preferably, the lashing is merely doubled, inserted through a grommet and looped over one of the end members 25, 27 ofa transverse bar 15, 17, 19, or 21. Then by merely taking up the slack, e.g., by first tying a knot and inserting the knot in an opening 54in an upper or lower end cap on the side frame member 11 or 13, or into a similar opening 112 in one of the plugs 25, the whole load is quickly secured in place and can be unfastened almost instantly.
FIG. 15 shows an arrangement wherein an upper bag 1 and a lower bag 2 are spatially separated. The bags are here seen as having a top flange, as at 240 on bag 2 and bottom flanges 241 on bag 1 and 242 on bag "2. These are equipped with grommets 245 as needed to supplement those in the side flaps. With the arrangement of FIG. 15, an additional bag, not shown, or some other package or article, may be loaded onto the pack frame between the two bags. It will be noted here that the lower bag has a weatherproof integral or hinged cover 250. Part of this is visible in FIG. 14.
FIG. 16, the larger or upper bag "1 of FIG. 14 has been removed and the lower bag "2 has been moved nearer the top of the pack frame F in its place. In FIG. 17, the bag "2 is lashed to the frame F in an intermediate position.
FIGS. 14, 16, and 17 also show a body belt 110 which is secured through a ring 92 to the side members 11 and 13 of the pack frame F. The ends of such belt are shown secured to side frame members 11 and 13, in FIG. 1 and the belt 110 is shown with multiple grommets g g and g, in FIG. 2. This belt is found by experience to be extremely useful. It makes it possible to switch the burden of the load from the shoulders or partially from the shoulders to the hips and abdomen of the wearer. On a long hike, it is very helpful to make such changes from time to time. The belt 110 is secured by the same key ring element 92 already mentioned, which also holds the lower ends of the shoulder straps 90, 91. For a thin person, the excess length of belt 110 can be cut off if desired at the second or third grommet to fit him better. The belt preferably is fitted at its front ends with a self-securing or selflocking material such as Velcro, a looped nylon material having interlocking elements by means of which the belt ends can be instantly secured together in any desired adjusted position. The Velcro fastening elements are indicated at V1 and V2 in FIGS. 1 and 3.
Various ways for securing the lashings L are shown in FIGS. 14, 16, 17, 18, and 19. In FIGS. 14, 16 and 17, the lashing is secured at the bottom by a knot (not visible) inserted into the openings 54 of bottom cap (or foot) member 51. In FIGS. 16 and 17, the upper ends of the lashings are passed through the notches in upper cap members 51. In FIG. 17, the lashings terminate in knots inserted in the opening 54, as they do at the bottom. In FIG. 16, they are tied together across the frame as shown at 270, 271. FIGS. 18 and 19 show the looping of the lashing L through a grommet 227 and around the projecting end of a cross member 15 (or 17, etc.) Single or multiple turns may be used as shown at 280 in FIG. 16 and at 281 in FIG. 17.
It will be understood that numerous other arrangements are feasible and will suggest themselves to those who are skilled in the art. The versatility of this pack equipment in itself will suggest many variations in form and arrangement of the various components and their manner of assembly and use. A particular variation that deserves emphasis is the possibility of manufacturing the components and selling them as a kit for assembly by the buyer. The whole frame assembly may thus be produced. Also, the user may buy separate components at different times, such as a single bag, or extension side members 40, even supplemental cross members, supplemental body webbings, etc., if desired. By cutting and furnishing the lashing elements L in standard appropriate lengths, these may be used singly to tie on single bags such as 1 or "2, for example, or looped or knotted together, may be used in pairs as quadlines, as in FIG. 10, etc., or as tension members 87 for the body web pairs.
It is intended by the claims which follow to cover the above and other obvious arrangements and modifications, such as would suggest themselves to those skilled in the art, as broadly as the state of the prior art properly permits.
