Description:
FIELD OF THE INVENTION 
     An apparatus and method of providing, assembling, and producing a collapsible pack, structure, shipping container, or container made from plastic, rubber, or some other sheet material, which can be formed into a variety of shapes by means of using cord, webbing, rope, wire, tubing or other flexible material, in combination with a variety of flexible fasteners, washers and O-rings to form a semi-rigid and abrasion resistant, container or structure is described. 
     BACKGROUND 
     The outdoor adventure industry continues to search for improved durability and flexibility in the material storage and transport used in small and large expeditions, such as those associated with climbs into the Himalayan Mountains in Nepal. 
     SUMMARY 
     Improved apparatus and a method of providing elements for their assembly are described. A collapsible durable outdoor adventure container includes a polymer sheet having at least two flaps and a pattern of through holes therein, wherein the through holes are positioned at prescribed locations and at intervals along a selected seam line for a frame of the container to be assembled by bending the flaps to a configuration wherein particular sets of complementarily matched through holes in the pattern are approximately coaxially aligned to form an aligned arrangement and secured in the aligned arrangement by a clamping element passing through the complementarily matched through holes causing the surfaces of the sheets adjacent such complementarily matched through holes to be held in a clamped condition by the clamping element. A strap running generally along said seam line is positionable to engage and be fixed to at least several of said clamping elements to be coupled to the polymer sheet and provide structural support to the frame and distribute a lifting force applied to the strap along the clamping elements positioned along the seam line of the polymer sheet. The frame of the container to be assembled can form the shape of a pack such that the sheeting is folded or bent so that said through holes align to provide a tubular shape closed at a bottom end. The clamping elements can be cable ties, which are individually tensioned to hold the adjacent sheet holes in alignment and in the clamped condition. The strap can be a rope held inside of a tension loop of the cable tie. The holes in the sheeting are spaced at least an inch apart and the through hole diameter is slightly larger than the width of a cable tie disposed to pass therethrough. The cable tie tension loop can pass through a washer element on the inside of the container to be assembled. The cable tie tension loop can pass through a washer element on the outside of the container to be assembled. A cable tie tension loop connector can be positioned outside the inner surface of the container to be assembled. The frame of the container to be assembled can form the shape of a pack such that the sheeting is folded or bent so that the through holes align to provide a tubular shape closed at a bottom end, and a light fabric material inner pouch is configured to be supported within and coupled to the tubular shape closed at the bottom. The frame of the container to be assembled forming the shape of a pack can be formed from at least two polymer sheet elements each having complementarily matched through holes that when aligned form a seam line along which connection points clamp adjacent surfaces of the sheet together such that the combination of two or more polymer sheets then form a sheeting assembly that is folded or bent so that said through holes align to provide a tubular shape closed at a bottom end. The at least two polymer sheet elements may have different thicknesses. A light fabric material inner pouch may be configured to be supported within and coupled to the tubular shape closed at the bottom. The polymer sheet may be a self reinforced composite. The cable ties may be rated for 50 lb continuous tensile load. 
     A method of supplying a collapsible durable outdoor adventure container comprising the steps of: obtaining polymer sheet material; configuring the polymer sheet material with through holes therein in at least flaps of the polymer sheet material such that when the so configured polymer sheet material is hinged or bent into a tubular arrangement, selected ones of the through holes are aligned to form a seam line, which when clamped in such tubular arrangement, form a durable outdoor adventure container; supplying clamping elements sized to pass through the through holes and bring the polymer sheet material adjacent the through holes into a clamped condition; and facilitating the use of a strap to be engaged with the clamping elements along the seam line. The through holes may be configured at least one inch, but no more than six inches between adjacent through hole along the seam line and the polymer sheet material may be a self reinforced composite.

     DETAILED DESCRIPTION 
     A rectangular transfer case shown in  FIGS. 1 to 8 . The transfer case can have a length, width and height of 62″, which is currently the maximum size container airline passengers are allowed to check-in without oversize penalties. A variety of shapes and sizes of containers can be made using the construction details and materials described. 
     One advantage of this method of construction is that the containers or structures can easily be disassembled for ease of shipping or storage. The flexible sheet material used in the Rectangular Transfer Case is lightweight yet far more abrasion resistant and durable than woven fabrics currently used in duffle bags or soft luggage. Flexible sheet materials, that do not hydrolyze and do not have polyurethane coatings that tend to deesterfy over time, can be used to make products that are very durable and long lasting. Manufacturing is greatly simplified since the flexible sheet material can be cut with steel rule dies, waterjet cutting systems, lasers, or with scissors. 
     The Rectangular Transfer Case was originally designed so mountaineering expeditions can ship their gear and provisions to base camp at Mt. Everest without having to discard the empty containers somewhere in the mountains of Nepal. Currently shipping gear and provisions to Mt. Everest base camp involves air, truck or sea shipments to Katmandu and Lukla, Nepal. From Lukla either Sherpas or yaks carry the gear, for approximately 8-12 days, to Mt. Everest base camp which is located at an 18,000 foot elevation. Once the provisions have been transported to base camp, in molded plastic, fiberglass or metal containers then these hard cases are discarded since it is not cost effective to return the containers to Lukla or Katmandu and then ship the empty containers to the owner&#39;s home port. 
     One advantage is that numerous Rectangular Transfer Cases can be disassembled, rolled up, and placed inside one fully assembled Transfer Case and then shipped home for use at a future date. The potential cost saving is significant! There is an added environmental benefit when applying this technology to shipping goods with products made as described herein rather than using disposable or recyclable cardboard or plastic shipping containers which are recycled or discarded after use. 
     Rectangular Transfer Case 
       FIGS. 1 to 8  show the parts and procedure for assembling a collapsible and reusable rectangular transfer case. 
       FIG. 1  shows an example of the parts needed to assemble a transfer case. There are two units of die cut flexible sheet material  100 , 2 washers  135  per cable tie fastener  105 , 4 O-rings  110  and a length of new or used rope  115 , strapping, or other flexible material. The flexible sheet material  100  has large diameter holes  80  at one end panel (flap) to accommodate the opening and closing that takes place during packing and unpacking to accommodate the O-ring which are attached to the cable ties, in lieu of the strap or rope passing through and small diameter holes  150  where no O-rings are used. The larger fixed and slightly elastically stretchable diameter of the O-rings allow a gathering and capture of a double layer of rope or strapping used on the perimeter along the seam line of the holes. The rope acts as a perimeter flexible backbone which captures and acts as a securing element on the perimeter which contains the bulk of the container while being tied in to the container at distributed at several locations, e.g., the cable tie and through hole connection locations. The washers and cable ties are sized to prevent slippage of the cable tie securing (cam or one way motion locking) elements from passing through the hole in the center of the washer. When the securing element (cam lock) element of the cable tie is not positioned or configured to make an interference fit with the washer(s) that it is coupled through a two hole button is used as can be seen in  FIGS. 3A and 4A . 
       FIG. 2  shows the upper  120  and lower  125  half configurations of the flexible sheet material  100  and how they are folded to begin assembly. 
       FIG. 3  shows how a cable tie  105  and two washers  135  (one on the outside and one on the inside surface) are placed through a small diameter hole in the flexible sheets  100 .  FIG. 3A  shows the cable tie securing element on the outer surface of the container. 
       FIG. 4  shows the rope  115  threaded through the cable tie  105  loop  155 .  FIG. 4A  shows the cable tie securing element on the outside surface of the container with the rope or strap passing through the cable tie cinching loop in preparation for being tightened. 
       FIG. 5  shows the cable tie  105  cinched (clamped) down  160  creating a clamping force to secure the rope  115  and sheets together. 
       FIG. 6  shows that O-rings  110  being attached in the same manner as the rope  115  in  FIG. 5 .  FIG. 6  also shows which direction the plastic flaps  180  are folded  190  to form an enclosed space  200 . 
       FIG. 7  shows the plastic flaps  180  are secured with the O-rings  110  positioned on the outside of the plastic flaps  180 . The plastic flaps  180  are held securely in position by threading the rope  115  thru the O-rings  110 . 
       FIG. 8  shows a fully assembled and closed Transfer Case  50 . The ends of the rope  115  have been tied together in a knot  210  fully securing and “locking” the plastic flaps  180  in position to keep them from accidentally opening. 
       FIG. 18  shows an alternate method for closing the Transfer Case  50 . The rope  115  is threaded through the large diameter holes  80  in the plastic flaps  180  prior to being threaded thru the O-rings  110 . The large diameter holes  80  need to be large enough to fit either rope  115  or webbing. 
     Triangular Case 
       FIG. 9  shows different cross sectional shape possibilities. Rectangular  225 , triangular  250  and round  275 . 
       FIG. 10  shows a triangular case  300 . 
       FIG. 11  shows a knot  210  which holds the triangular case  300  closed. 
       FIGS. 12 and 12A  show the general shape and details of the flexible sheet material  100  used for making a triangular case  300 . Large diameter holes  80 , rope  115 , small diameter holes  150 , cable ties  105 , and washers  135  are shown in the diagram as well. 
       FIG. 13  shows the rope  115  being threaded through the cable tie  105  loops  155 , at the bottom  145  of the triangular case  300 , prior to cable ties  105  being cinched tight to clamp the elements together. 
       FIG. 14  shows the cable ties  105  on the bottom  145  of the triangular case  300  with the cable ties  105  cinched tight. 
       FIG. 15  shows the complete triangular case  300  in its closed and secure configuration with a knot, e.g.,  210 , see  FIG. 18 , holding the triangular case  300  closed. 
       FIG. 16  shows how a plurality of triangular cases  300  can stack in a space saving manner. 
       FIG. 17  shows that cases that have a generally rectangular  225  cross section are not as strong as cases made with a triangular  250  cross section. 
     Handbag 
       FIG. 19  shows a handbag  315 . 
       FIG. 20  shows the shape of the flexible sheet  100  which when assembled will form into a handbag  315  shown in  FIG. 19 . Please note the slot  165  with a slot space  320  will position the rope, strapping, or webbing  220  ( FIG. 21 ) in a manner that holds the handbag flap  285  closed. The slot space  320  allows the rope  115  or webbing  220  to hold the handbag  315  ( FIG. 19 ) flap  285  closed. 
       FIG. 21  shows webbing  220  can be used to assemble the flexible sheets  100  instead of a rope, wire, flexible tube or other flexible material. 
       FIG. 22  shows an alternate method of assembling the handbag  315  using rope or webbing  220 . 
       FIG. 23  shows the flexible sheet material  100  with large holes  80 , a slot  165  and slot space  320 . 
       FIG. 24  shows an alternate method of assembling the flexible sheets  100  that are held together to form the handbag  315  in  FIG. 22 .  FIG. 24  shows how the webbing  220 , rectangular slot washer  420  and a slotted 3 bar fastener  325  (shown in  FIG. 24  and  FIG. 25 ) are assembled to secure the flexible sheet material  100 . Please see  FIG. 55  to see a detailed view a rectangular slot washer  420 . 
     Packs 
       FIG. 26  shows a flexible sheet material  100  which, when folded and assembled, will form a pack. The through holes shown, can be matched up when folded or bent and particular preconfigured sizes can be can be selected by picking one of several alternative sets of matching holes. Also, bowing of the pack wall can be accomplished and facilitated by slightly different spacing of adjacent sheet elements. Like a bimetallic strip a longer element will create a permanent bend (a fixed band) in a prebowed (curved) relationship between the two adjacent elements of differing length. 
       FIG. 27  shows a waterproof bag  340  which can be placed inside the pack opening  335  ( FIG. 28 ). This is a convenient feature for backpackers since the pack  330  can be left outside the tent while the removable waterproof bag  340  can be placed inside a tent. 
       FIG. 28  shows the pack  330 , shoulder straps  350 , handle  290 , pack opening  335  and removable waterproof bag  340 . The pack can be assembled with webbing  220  ( FIG. 29 ) washers and cable ties or with rope, washers and cable ties. The user can put whatever fits into the pack  330  but if the user desires a method to keep the contents dry then a removable waterproof bag  340  ( FIG. 27 ) can be placed inside the pack opening  335 . The alternate assembly method shown in  FIG. 24  and  FIG. 25  can be used to assemble the pack  330 . 
       FIGS. 29 and 29A  show the pack  330  assembly detail using webbing  220 . 
       FIG. 30  shows a side view of the pack  330  with a removable waterproof bag  340 . The waterproof bag  340  is in the open position  345 ,  FIG. 30  also shows adjustable shoulder straps  350  and a webbing handle  220 . 
       FIGS. 31 ,  31 A, and  31 B show the shoulder straps  350  can be detached from the pack  330  using a removable slider buckle  355  shown in detail in  FIG. 32 . The removable slider buckle  355  allows the length of the webbing to be adjusted to the users&#39; desired comfort. The removable slider buckle  355  can be used as a quick release feature should there be a need to remove the pack  330  quickly. Removing the pack quickly would be very advantageous if someone fell through the ice on a frozen lake for example. 
       FIGS. 33 ,  33 A, and  33 B show an alternate pack  330  shape and usage. 
       FIG. 34  shows a larger pack  330  designed to carry heavier loads with comfort. The removable waterproof bag  340  can vary in size depending on the users need. 
       FIG. 35  shows the cable tie  105 , washer  135  and rope  115  assembly method used with one layer of flexible sheet material  100 . This is a desirable feature should the user need to attach items such as skis or an ice axe to the rope  115  in  FIG. 34 . 
       FIG. 36  shows a side view of the pack  330  with a removable waterproof bag  340  inside and having open sides, which produces the weight and stiffness of the polymer sheet (structural element—frame). 
       FIG. 37  shows the back panel of pack  330  ( FIG. 36 ). The handle  290 , shoulder straps  360 , lumbar pad  365  and hip belt  370  unit are attached to the flexible sheet material  100  forming a more comfortable method of carrying heavier loads. 
       FIG. 38  shows the shape of the flexible sheet material  100  used to produce the larger pack  330  shown in  FIG. 34 .

       FIG. 41  shows a removable slider buckle  355  which is used to securely fasten the webbing  220  around the user&#39;s waist. 
       FIG. 42  shows an alternate method of assembling the flexible plastic sheet  100 A, to form a pack  330 A. In this case the cable ties  105 , washers  135 , rope or webbing are all attached on the same panel as the hip belt  370  and shoulder harness  375 . 
       FIGS. 43 and 44  show pack  330 A with a removable waterproof bag  340 A securely fastened to pack  330 A by threading the webbing closure  405 A, of the removable waterproof bag  340 A, through an opening  385  in the flexible sheet material  100 A. 
       FIGS. 43 and 44  also show an ice axe loop  380  that is sewn to the removable waterproof bag  340  and is guided through an opening  385  in the flexible sheet material  100 . 
       FIG. 45  shows a waterproof bag  390  permanently or semi-permanently attached to the flexible sheet material  100  which forms the pack  330 . The attachment means can be make with nuts and bolts, cable ties, welding, radio frequency welding, carabiners, snap clips, snaps  395 , quick links or any such means as to keep the waterproof bag  390  from falling out of the pack  330 . 
       FIGS. 46 and 46A  show multiple flexible sheets  100 B, C, D, E, F which, when folded and assembled, will form a handbag  315   FIG. 47 .  FIG. 47  also shown is a removable waterproof bag  340  placed inside the multiple flexible sheets which form the handbag  315 . The rope  115  or webbing in  FIG. 47  is one continuous piece connected with a knot or fastened by some other means such as sewing or welding. 
       FIG. 48  shows a rope  115  that forms a triangle and is separate from the shoulder strap  360 . The rope forms a continuous loop with a knot  21 A 0 . A rope  115  or any number of rope  115  segments can be used to form the flexible sheet material  100 G into nearly an infinite variety of shapes. 
     Handbag with Removable Waterproof Bag 
       FIG. 49  shows a flexible sheet material  100 H which, when folded and assembled, will form a handbag  315  with foam pad  400 .  FIG. 49  shows the shape of a handle  290  which is produced by cutting an opening  385 , of the desired shape, in the flexible sheet material  100 H. 
       FIG. 50  shows a removable waterproof bag  340  securely fastened to the handbag  315  by threading the webbing closure  405  of the removable waterproof bag  340  through an opening  385  in the flexible sheet material  100 H. 
       FIG. 51  shows a removable waterproof bag  340  with webbing closures  405 . Alternate method of securing multiple layers of flexible sheet material without cable ties 
       FIG. 52  shows an alternate method for securing the flexible sheet material  100  without the use of cable ties. The flexible sheets  100  can be secured using a smaller diameter cord  410  and a cord-securing clip  415 . The cord-securing clip  415  can be attached to the cord  410  by attaching the cord securing clip  415  to the cord  410  by pushing the cord  410  through the slots  165 . This method is quicker than if the cord-securing clip  415  only had holes with no slots because then the cord  410  would have to be threaded through each individual hole taking a significantly longer time to assemble the product. 
       FIGS. 53 and 54  and their associated Figures show alternate cord-securing clip shapes. 
       FIGS. 55 and 55A  shows an example of a rectangular slot washer  420 . 
       FIGS. 56 and 57  show the assembly of a pack arrangement where the flaps are a different material thickness than the midline sheet material. This arrangement allows there to be a vertical stiffness structural integrity in the support of weighted elements in the pack and in the connection to the shoulder straps and waist belt, while allowing a lightweight and easily bendable in a tight radius side panel flaps. Together the mid-palate inside flaps form a sheet assembly. 
     There is a special source for the sheet material. Curv® self-reinforced composites, is a new concept in thermoplastic materials that bridges the gap between commodity plastics and traditional fiber-reinforced materials. Curv® is referred to as being “self reinforced” because it comprises high-performance thermoplastic fibers in a matrix of exactly the same material. Curv® is 100% polypropylene (PP), but yields stiffness and strength values around five times those of regular PP. In addition, Curv® has a high strain to failure which in combination with good tensile strength offers tremendously high impact resistance, even at temperatures as low as −189° C.! The material also has exceptional abrasion resistance as well as tensile of strength. Application areas today are manifold: suitcases, sports equipment, automotive parts (interior &amp; exterior), anti-ballistic products, etc. Curv® is used as a skin material in light-weight sandwich structures, usually in combination with thermal plastic core materials. 
     Curv® can be supplied on a roll or as a sheet in thicknesses from 0.35 to 2.9 mm, maximum width of 1360 mm and any length. The manufacturing process is very flexible and offers excellent possibilities for tailor made solutions. Curv® can be combined with materials like aluminum, glass-, aramide-, and carbon fibers, resulting in a totally new range of thermoplastic composites for a wide range of cost and performance targets. 
     The Curve Propex is one type of material used for the backpacks. It comes in black only and in numerous thicknesses (0.35 mm, 0.66 mm, 1.00 mm, 1.34 mm, 1.68 mm, 2.02 mm, 2.36 mm, 2.70 mm and 2.95 mm. The white material, used to make transfer cases and transfer case is an extruded sheet material and is a commonly available “High Density Polyethylene”. A 0.030″ thick material is used for most transfer case applications. Various thicknesses of Propex or High Density Polyethylene can be used or combined to create stiffer or more flexible areas which is especially desirable for packs. The manufacturer is Propex Fabrics GmbH. 
     Special cable ties that are used with rounded on the edges which minimizes abrasion. The cable ties are made of UV resistant nylon 6.6 with stainless steel keeper. Operating temperatures of −40 degrees F. to 185 degrees F. The manufacturer is Thomas &amp; Betts. 
     The washers are die cut out of the sheet materials described above or we use stainless steel washers purchased from McMaster-Carr are used. 
     The rope or webbing is rated for climbing. The pack can be disassembled and the webbing or rope can be used as a belay device. The John Howard Company provides the webbing. Sterling Ropes provides the braided rope. 
     The mechanism by which the waterproof bag is sealed is that the opening of the bag is held closed and then rolled. The rolled fabric is held in place by plastic side release buckles. UTX and National Molding, Corp. make such items. 
     Dry Bag Closure provide a water resistant or proof material which when it does not have an air tight seal such as when using a zip-lock plastic element interlocking groove type seal, is well known in the art to have a sealing end which is rolled up (wound tightly on itself in a tight roll) and then a belt or strap attached to half of the opening circumference is locked by a buckle in a loop, to thereby resist unraveling (or unwinding). 
     The waterproof bag is a polyether coated nylon fabric with a 2,000 mm to 20,000 mm hydrostatic head waterproof rating. The bags are assembled either with RF welding the seams or by sewing and then hot taping them. Shapes vary but most waterproof bags are square, rectangular (most common) or cylindrical (also common). Sizes are infinite and only limited by what a few people can lift by hand. 
     Preventing the waterproof bag from being ruptured by the washers around which the tie wraps are secured on the inside surface of the box, bag, and pack structures. 
     The terminal ends of the cable ties can be configured to be on the outside of the pack so there are no abrasion points on the inside (see  FIGS. 3A ,  4 A). The washers and flat portion of the cable ties do not affect the waterproof bag fabric. 
     In the pack configuration, there are straps through the holes in the sheet material, which allow the bag to have lots of slack before the limit of motion of the inner bag from the surrounding flexible sheet material frame is reached. Generally the inner bag will be held in the pocket shape of the pack frame/sheeting by gravity. 
     Attachment of an ice axe to the ice axe loop extending from the bottom section of the inner bag and through a corresponding opening in the outer structural wall will significantly limit the upward motion of the waterproof bag. Holes or slots can be punched into the sheet material in a manner that the webbing on the waterproof bags will lock the bag into position. 
     The flexible sheet material needs to hold its shape when the pack is fully loaded. Packs are used to carry weight comfortably. This is done (by the pack) which transfers the weight and being carried to users shoulders and waist. The flexible sheet material needs to be stiff enough to be able to transfer the weight from the bag to the shoulders and hip belt, yet not so flexible that it deforms under its own weight when not loaded. Comfort is increased if the pack can flex with the body&#39;s movement. The flexible sheet material will also act as an exoskeleton for the inner waterproof bag, so that the inner bag may be made of lighter weight fabrics, this will in turn allow for less total weight. 
     The flexible sheet material will have a higher resistance to most types of abrasion, more than any woven fabric of a comparable weight. In addition the flexible sheet material holds a higher water resistance than most fabrics especially after prolonged UV exposure. 
     Cable ties are needed since they hold the webbing or rope in place. This allows the user to use the webbing or rope as tie out anchors where you can attach things to the pack. Handles can be formed by adding extra rope or webbing between cable ties. This would not be possible without cable ties. The cable ties used have a minimum breaking strength of 50 lbs. In contrast, hand stitching or sewing films and sheet composites creates weak spots where the needle holes are. This system has the advantage that there is a certain distance (generally not less than one inch and not greater than six inches) between holes so the integrity and strength of the fabric are maintained. Sewing creates a long line of small holes than allows the film or composite to crack along the seam line. 
     In contrast to using cable ties when the rope or strapping was threaded using the threading method (as shown in the figures), the trouble was that the rope or belt materials stretch and do not hold the plastic sheets in close tight contact alignment because the only thing holding the plastic in place is the tension experienced in the slack threaded rope. When a user laces something, like a shoe, only the knots at the end hold things in place and the user is counting on the tension in the slack portion of the rope keeping everything aligned. With the cable ties you lock the webbing and plastic in position which allows you to create curved structures that will keep their shape. 
     The rope or webbing is not ornamental. The structure can be made without a rope or webbing. Rivets or bolts could be used to hold the plastic sheet material together. The trouble is that then there is no tie loop to work with, unless they are specially added to the bolts or rivets. With the current configuration of using a perimeter rope along a seam line of connecting and aligned through holes in the polymer sheet material overall support and stability and a second outside supported element (the rope) helps maintain the container integrity. If a user trips and falls and the plastic cracks, then in the present configuration the rope will still hold the pack together. The rope/webbing system also allows you to quickly disassemble the pack for transport (using reusable-releasable cable ties) and later assemble the pack for use. Imagine having 20 packs that need to be put in a Cessna 210 (bush plane) for transport. Rivets will not allow you to easily disassemble the pack. Nuts and bolts would work but then adding tie outs to them is problematic and using any one of the anchors might create a weak spot. The rope or webbing distributes any stresses when used to anchor things to the pack. The rope/webbing system allows a greater variety of anchor points with witch to attach things to.\
