Gray, Metolius, Oreg., assignor, by direct and mesne assignments, to James B. Minturn Filed Aug. 15, 1963, Ser. No. 302,344 8 Claims. (Cl. 2248) This invention relates to a combined takedown packboard and expansible packsack, and more particularly to a lightweight, rugged, takedown packboard and a packsack therefor.
There has been a great need for a strong, rugged, lightweight packboard which may be taken down and compacted. Takedown packboards have been known in the past, but they have not been satisfactory because they have not been sufliciently rugged and durable to withstand -hard usage, and they have not been light in weight. They also have been diflicult and expensive to make, and have been complex in structure, which aggravated these problems. It would be desirable to provide a simple, rugged, lightweight, easily made packboard. It also would be desirable to provide a packsack which is expansible.
An object of the invention is to provide a new and improved takedown packboard and expansible packsack.
Another object of the invention is to provide a packboard in which a plurality of lightweight cross-members are locked together by a saddle and are bowed away from the saddle by pulling the side members toward one another.
A further object of the invention is to provide a packboard having a pair of angle side members having a plurality of pairs of means for retaining the end portions of slats against movement away from the bases of the angle members while permitting endwise movement of the slats away from the angle members, together with a saddle secured under tension to the free ends of the flanges of the angle members to flex the slats and bow them away from the saddle.
Yet another object of the invention is to provide a takedown packboard which is formed substantially completely from extruded aluminum elements.
Another object of the invention is to provide a packboard frame having side members provided with notches at the upper ends thereof for receiving loops of a strap supporting a packsack on the packboard.
Yet another object of the invention is to provide a packboard frame having a pair of angle members having bases provided with ribs rushed up out of the plane of the bases with portions of the ribs sheared from the bases to form loops extending beyond one face of each of the bases for receiving slidably therein slats.
Still another object of the invention is to provide a packboard frame having a pair of side members provided with flanges together with lashing strips secured in pairs to the outsides of the flanges and provided with hook portions at the ends thereof for lashings.
A still further object of the invention is to provide a packsack having a front panel and a rear panel, together with an expansible pleat connecting the front panel and the rear panel.
The invention provides a takedown packboard including a plurality of slats, a pair of side members having portions interlocking with the end portions of the strips, together with a saddle secured under tension to such portions of the side members spaced laterally away from the strips as to bind the side members to the slats. Preferably one of the slats positioned near the upper end of the packboard has a plurality of pairs of holes spaced therealong adapted to be selectively secured to snap hooks fixed to the upper ends. of shoulder straps. Also, the slats are preferably interchangeable and are adjustable up and down the side members and may be secured in selected receiving and intorlocking portions in the side members. In a packboard forming one specific embodiment of the invention, the side members are composed of extruded aluminum angle members having base portions provided with ribs extending therealong spaced from flanges of the angle members, with portions of the ribs punched out and formed into loops spaced away from the inner faces of the bases, and the slats fit loosely and siidably through the loops with the ends thereof abutting the flanges of the angle members, a saddle being lashed at opposite side edges thereof to hooks on the outer edges of the flanges to tend to turn the angle members about their longitudinal axes and bind the angle members to the slats. Preferably the angle members have upwardly facing notches formed at the upper ends thereof for receiving loops in a strap secured to a packsack, which preferably is selectively usable in a compressed condition in which a pair of zipper elements secured respectively to a back panel and a front panel thereof are secured together, and an expanded condition in which the zipper elements are unlocked from each other, and a flexible strip of substantially greater width than that of the combined width of the zipper elements secures the panels together in expanded positions.
A complete understanding of the invention may be obtained from the following detailed description of a combined takedown packb card and col-lapsible packsack forming a specific embodiment thereof, when read in conjunction with the appended drawings, in which:
FIG. 1 is a perspective view of a combined takedown packboard and collapsible packsack forming one embodiment of the invention;
FIG. 2 is a View similar to FIG. 1 but with the packsack in a flattened or collapsed condition;
FIG. 3 is a perspective view of the packboard of FIG. 1;
FIG. 4 is a front elevation view of the packboard of FIG. 1;
FIG. 5 is an enlarged, horizontal section taken alon line 55 of FIG. 4;
FIGS. 6 and 7 are similar, enlarged, fragmentary, horizontal sections of a portion of the packboard of FIG. '1 with corresponding elements in different conditions; and
FIG. 8 is a fragmentary, perspective view of the packboard of FIG. 1.
Referring now in detail to the drawings, there is shown therein a combined takedown packboard 10 and a collapsible packsack 12 forming a specific embodiment of the invention and forming a combined pack unit. The packboard 10 includes a pair of allochiral side angle members 14 and 16 composed of extruded aluminum or other suitable lightweight metal having bases 18 and flanges 2t). The angle members have rounded beads 17, 1% and 2,1. The bases 18 are provided with olfset grooves 22 and ribs or ridges 24 from which, as spaced portions along the angle members on bases 18, are punched shallow loops or straps 26 for retaining strips or slat 28 and permitting the ends of the slats 28 to slide freely therethrough. At least one of the slats 28 positioned either in the uppermost pair of aligned loops 26 of the angle members 14 and 16 or in one of the two pairs of loops therebelow, is provided with pairs or" holes 31 to 36 to which a pair of snaps 4t) fixed to the upper ends of straps 42 may be selectively secured. If desired, both the upper slats 28 may be provided with the holes 31 to 36 therein for connecting the upper ends of the straps selectively thereto. Also, the straps may be secured to the slat 28 just below the uppermost slat and may extend directly to the shoulders of the user, the straps crossing over as they so extend, or the agaasoa straps may be positioned as illustrated in FIG. 8 with the snaps 40 secured to the next to the top slat 28 and extending back of the uppermost slat 28 and then cross over and pass over the tops of the shoulders of the user to avoid any necessity of a head strap. The lower ends of the straps 42 are provided with snaps 46 which may be positioned selectively in holes 48, 50 and 52 spaced along the lower portions of the flanges 20 of the angle members 14 and 16. The lower ends of the straps 4-2 also have length-adjusting buckles 54 (FIG. 4') of a known type.
The ends of the slats 28 are square and abut the inside faces of the flanges 20 (FIGS. 4 to 7) at the corners formed by the flanges 2t} and the bases 18 of the angle members 14 and 16, and the outer or free edges of the flanges :14 are pulled toward one another by a canvas saddle 66 having side edge stays 69 and a pair of lacings 62 which hook under eyes or hooks 64 of straps 66 riveted to the outside faces of the flanges 20. The straps'66 also have hooks 68 positioned at the other ends thereof 'for securing lashings strapping loads onto the packboard. The lashings 62 are secured at the lower ends thereof to the lowermost hooks 64, pass through grommet 70 in the canvas saddle 60, back to the lowermost hooks 64, then to the next hook 64-, to the next grommet and back to that same hook, and so on, to the uppermost hooks 64 to which the lashings are secured. The lashings 62 are under tension and tension the saddle 66 so that the outer, or forward, ends of the flanges 20 are pulled toward each other and turn to the extent permitted by the slats 23 to move the loops 26 tightly against the slats 28 and to compress the slats 28 somewhat along the longitudinal axes of the slats. This causes the slats to bow outwardly slightly relative to the saddle 60 and also to press hardagainst the flanges 20 to secure the slats and the angle members 14 and 16 rigidly against movement relative to each other. This makes the packboard very rigid. The lashings 62 are free to slide in thegrommets 7t) and in the hooks 64 so that the saddle 69, which lies against the back of the user of the packboard, will conform to the shape of the back of the user automatically. This gives maximum comfort to the user.
At the upper ends of the angle members 14 and 16, as viewed in FIGS. 1 and 2, there are provided upwardly facing U-shaped notches 89. This leaves binding post portions 82 formed by the upper ends of the bases 18. The packsack 12 has a flexible strap 84 stitched to the back face thereof. The strap 84 is provided with loops 86 at the ends thereof which fit over the post portions 82 and into the notches 89 to secure the packsack 12 to the packboard. The packsack 12 also has two, lower positioned, flexible loops 88 which hook over a lower pair of hooks 68 to secure the lower portion of the packsack 12 to the packboard.
The packsack 12 is provided with a canvas back panel 92,, a canvas front panel 94 and a continuous side panel 96 having a zipper opening 98 therein at the top thereof. The packsack is expandable from a thin condition, as illustrated in FIG. 2, in which zipper elements 1% and 102, secured respectively to an intermediated portion of the side panel 96 and the edge of the back panel 92, extend completely around the side panel 96. The zipper element 100 is provided with a stop portion 164 and a known zipper slide or connector 106. Extending between the two zipper elements 190 and 1l 2 is a continuous pleat or gusset 110 which is folded when the zipper elements 100 and 102 are secured together by the slide 106 and stop 104, as illustrated in FIG. 2. In this condition the packsack is rather shallow or thin. However, when the slide 106 is actuated to separate the zipper elements 100 and 102 completely, the pleat 110 unfolds, and the packsack is quite deep, as illustrated in FIG. 1. The
packsack also includes pockets 112 and 114 having zipper The construction thereof is very simple and requires a minimum of fabrication effort. Obviously, the packboard may be used with the packsack or, if desired, the packsack may be removed and loads lashed convenientiy to the packboard, or loads may be lashed to the packsack and packboard while retaining the packsack on the packboard. The lashings 62 may be detached from the side angle members 14 and 16, the side members removed from the slats 28, and the side anglemernbers and the slats be positioned parallelly together to form a very compact unit for storage, which unit may be'carried is a small tubular bag (not shown). Takedown and reassembly is simple and rapid.
It is to be understood that the above-described arrangements are simply illustrative of the application of the principles of the invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.
