DETAILED DESCRIPTION

[0028] The entire disclosures of U.S. patent application Ser. No. 15/284,438 filed Oct. 3, 2016, which claims the benefit of U.S. Provisional Application No. 62/235,678 filed Oct. 1, 2015, entitled WHEELED BACKPACK CARGO HAULER are hereby incorporated herein by reference.

[0029] A cargo hauler that is wheeled and collapsible is described. The cargo hauler can be provided as a cart that folds with gear in the cart for use as a tote, an advantage that is unavailable in known carts. A loaded, folded cart can be unfolded and configured to be wheeled to transport the load. For example, if going from the house to the car, the loaded cart is folded, and placed in the car trunk. At a marina, the loaded cart is taken out of the trunk, unfolded and may be easily wheeled along a pier or quay to a boat, for example. There is no need to load and unload the cart during these transitions.

[0030] Some embodiments described below include a waist belt and/or shoulder straps to permit hands free hauling. Other embodiments provide a folding feature, which permits the cargo hauler to be used as a backpack, while loaded or unloaded. The cargo hauler may thus be used as a backpack, and converted to/from a cargo hauler. The cargo hauler may provide 67-75% weight savings over known carts. When folded, the cargo hauler may take up half the unfolded storage volume, which can be important for cruisers. The cargo hauler described here can be used with many types of vehicles, including scooters, bicycles and tractors. Adapters are provided to permit the cargo hauler to be attached to vehicles for transport.

[0031] The cargo hauler may be used with high speed vehicles, such as ATV's, Rokon's and lower speed dirt bikes. The cargo hauler is configurable to operate as a beach or lawn chair. The folding design of the cargo hauler permits use in confined areas for transport, such as small boat transport such as kayaks, canoes and row boats. Hunting applications permit the cargo hauler to be used to transport game such as deer, bear or fowl. The cargo hauler is useable in rough terrain where roads may be unavailable or not easily accessed, which is advantageous in camping or hunting applications. The cargo hauler may also be used for emergency applications to transport equipment in confined spaces, such as may be useful for EMS and for hands free transport of firefighting equipment, for example. Another useful application is for hands free cargo transport for parents, permitting parents to hold children, as well as permitting children/handicapped or disabled persons to be able to move/pick-up/discard items.

[0032] The cargo hauler design provides the advantage of transitioning from wheeling use, such as a cart usage, to use as a tote, while permitting cargo to remain loaded in the cart. Previous known carts typically operate with the user unloading cargo to fold the cart, and then reloading the cart after unfolding.

[0033] The cargo hauler is also capable of hands free hauling. Such useful operation is possible with the use of a backpacker's waist belt and/or the use of a shoulder harness/shoulder strap and/or straps. The straps or harness can be used with the folded cargo hauler for use as a day pack/backpack or as a carry tote. The cargo hauler may also be folded and placed in knapsack or backpack for transport and can also be transported using the straps or harness as a shoulder strap to carry the cargo hauler.

[0034] The cargo hauler includes a rotating beam or beams connected to rotating beam handles, which may be oriented in a vertical or other direction. The rotating beam can be actuated to fold/unfold the cargo hauler. The rotating beam may be connected to a front or a back of the cargo hauler, or both, and may be individually actuated to fold/unfold the cargo hauler.

[0035] Handles may be provided with the cargo hauler. The handles may be located outside of the wheels in a cart configuration to increase operator control and cart stability during hauling. The handles may extend and/or fold, with the folded or unfolded configurations of the cargo holder. Thus, a collapsed or folded cart configuration may be wheeled with the user gripping the handle(s) in an extended or retracted configuration. That is, there is no need to unfold the cart to wheel it to a given location. For example, the user may extend the folded cart handles and wheel the folded cart to a desired location where the cart may be loaded or unloaded. This feature permits loaded or unloaded cart access through areas with limited or narrow accessibility.

[0036] The cargo hauler may be configured to match a small boat deadrise or bottom geometry for stable and secure transport of a small boat. The hands free feature permits easy backwoods hauling of significant loads. The cargo hauler may also be configured with ski accessories for cross country or downhill skiing on snow during the winter. The ski accessories may be in addition to or to substitute for one or more wheels. The efficient and simple operating mechanisms of the cargo hauler, including the folding mechanisms, are lightweight and permit efficient folding/unfolding operation of the cargo hauler.

[0037] Referring now to FIGS. 2a, 2b and 2c, an embodiment of the cargo hauler with a waist belt 210 and a shoulder harness 214 are illustrated. Waist belt 210 and shoulder harness 214 are configured with attachment points 212 to connect the cargo hauler handles to the user for hands free transport. Additional harness attachment configurations permit direct attachment of the shoulder harness to cart handles to improve harness to cart pulling angles. These additional shoulder harness-to-handle attachments points may vary based on user height. Although the illustrated cargo hauler is single wheeled, it may also be configured to have additional wheels. Single wheeled cargo haulers may be used on improved traveling surfaces (roads, sidewalks, piers, docks, ect . . . ) and unimproved backwoods trails, or off road where no trails exist. The single wheeled hauler may thus be advantageous for use in narrow or rough terrain, where a multi-wheeled cargo hauler may be limited by its design width. Multi-wheeled cargo haulers may be advantageous for improved traveling surfaces due to their greater stability. Any of the hauler designs discussed here can have fixed or telescoping or fold out handles.

[0038] Single and dual wheel cart designs both may use waist belt 210 and/or shoulder straps or harness 214 (FIG. 2) for hands free hauling. Illustrated is hands free hauling for a single wheel cart design, similar waist belt 210 and/or harness 214 may be used for multi-wheel designs. Commercial harnesses are available from Cairns and cargo equipment and backpack suppliers. Commercial harness shoulder straps and waist belt have features that allow both shoulder straps 214 and belt 210 to attach independently to cart handles.

[0039] Referring now to FIGS. 3a-3g, a multi (two)-wheeled hauler design is illustrated. The illustrated hauler includes vertical beams 312 near a center of the hauler that permit compact folding operation, provide strength to carry hundreds of pounds of cargo and are connected to operate by one or more rotating beams 310 that use a moment to fold/unfold the cart. The use of the beams in a center of the hauler is not known in previous cart designs and provides several advantages for compact folding and efficiency of operation.

[0040] A distinctive feature of the hauler design is a direct load path from a bag support beam 314, through the wheel frame to tires and kickstands that react the load. The cargo hauler configuration in FIGS. 3a-3g includes rotating beam handles 310, which are two pieces of bent tubing located either side of the cart that connect to vertical rotating beams 312. To fold the cart, rotating beam handles 310 are urged upward, which displaces vertical rotating beams 312 downward. The process is reversed to unfold the cart, e.g., rotating beam handles 310 are urged downward to displace vertical rotating beams 312 upward. Vertical rotating beams 312 can be configured to be displaced upward as well as downward in a folding operation. Vertical rotating beam 312 can be composed of a single or multiple beams. Multiple beams can be adjacent or separated at some distance.

[0041] The cargo hauler has three sections, which are on either side of bag support beams 314. The wheels of the cargo hauler are relatively small to contribute to ease of carrying when the hauler is used as a tote, either folded or unfolded. The open construction of the hauler, where there is no frame or structure in the interior of the hauler, makes the frame lighter and provides more storage room, while making the hauler more easily used as a tote. Handles 316 are provided with a telescoping operation to permit the hauler to be compact, as well as easily used as a cart when handles 316 are extended. The cargo hauler becomes more narrow when folded, as shown in FIGS. 3c and 3g. Handles 316 are trapped in place when retracted and the cart is in the folded configuration, reducing the need to additionally lock handles in place.

[0042] Referring now to FIGS. 4a-4h, another embodiment of a two wheeled hauler is illustrated. FIGS. 4a and 4b show a configuration for a rotating beam handle 410 that is urged downward to fold the hauler. Rotating beam handle 410 is a section that extends beyond a center region of the hauler from vertical rotating beams 412. Pushing down on rotating beam handle 410 folds the cart. The process is reversed to unfold the cart.

[0043] Handles 416 telescope for compact stowage. Placement of handles 416, as illustrated, on the outer edges of the cargo hauler, improves cart stability while hauling.

[0044] The carts illustrated in FIGS. 3a-3g and in FIGS. 4a-4h have relatively small diameter wheels to permit the folding/unfolding of the cart while loaded to be achieved more easily. The smaller wheels also tend to make the design lighter. Known carts are unable to achieve these advantageous features, since they tend to have larger wheels, and are typically unloaded to permit the cart to be folded or unfolded.

[0045] Referring now to FIGS. 5a-5i, a variation of the operating mechanism in the cart and folding designs illustrated in FIGS. 3a-3g and FIGS. 4a-4h is shown. For example, hauling handles 516 are located under rotating beam handles 510 for compact stowage. Handles 516 can be extended while the cart is loaded or unloaded, and while being folded or unfolded, which permits transport of the folded loaded cart through tight areas. This advantageous and novel feature is unavailable in known carts. Handles 516 are shaped to match the contours of rotating beam handles 510. With such a design, handles 516 do not protrude outwardly from the hauler when unextended, so that a smaller profile for the hauler can be maintained. Handles 516 are also located outboard of the wheels of the hauler, which positioning can contribute to greater stability and control during use.

[0046] In addition, the wheels of the hauler illustrated in FIGS. 5a-5i are larger than those shown in FIGS. 3a-3g or FIGS. 4a-4h. However, the wheels are located inboard of the hauler, which permits a smaller profile for the folded hauler, as illustrated in FIGS. 5e and 5h.

[0047] The hauler illustrated in FIGS. 5a-5i can be folded by applying an upward force on rotating beam handles 510 to urge them upward and towards each other. This movement is transferred to connected vertical rotating beams 512 by bars 511, which are pivotally connected to and pivot about pivot points 514. The pivoting movement of rotating beam handles 512 and bars 511 is the same as that exhibited by rotating beam handles 310 and 410 and their connected bars that pivot about respective pivot points. As rotating beam handles 512 are moved upward and inward, bars 511, which are pivotally connected to vertical rotating beams 512, cause vertical rotating beams 512 to move downward. In the reverse, unfolding operation, rotating beam handles 512 are moved outwardly and downwardly, and may be moved away from each other, to cause vertical rotating beams 512 to move upwardly until positioned in the unfolded configuration, as shown in FIGS. 5a, 5g and 5h. A locking mechanism or detent system (FIGS. 5a, 5f) may be provided to retain the hauler in the folded or unfolded position. Rotating beam handles 510 are fabricated using bent tubing located either side of the cart that pivotally connect to vertical rotating beams 512. Bars 511 may be considered to be a component or a part of rotating beam handles 510

[0048] As with the haulers shown in FIGS. 3a-3g and FIGS. 4a-4h, a strap or straps (not shown) may be attached to rotating beam handles 512, which a user can gather together to lift and carry the hauler as a tote. When the strap(s) are gathered together, they pull rotating beam handles 512 together to move the hauler towards a folded position, and may also be used as a shoulder or carrying strap. As shown in FIG. 5i, one or more straps may also be attached to bag support beam 314 (FIG. 3e), and the equivalents shown in FIGS. 5g and 5h, for example, to be used as tote handles or shoulder or carry straps.

[0049] Referring now to FIGS. 6a-6j, a variation of the design illustrated in FIGS. 5a-5h is shown. Rotating beam handles 610 operates by being pushed down on the section of handle 610 that extends beyond a center of vertical rotating beams 612. Pushing down on the section of handle 610 folds the cart, while pulling up on or lifting the section of handle 610 unfolds the cart. Rather than the extension or moment being located beyond the centerline of the cart as illustrated, the moment can be located outboard of the wheel frame (FIG. 7). In this example, rotating beam handles 610 are combined or reduced in size, and are actuated with the section of handles 610 that extends past the centerline of the hauler.

[0050] Referring now to FIG. 7, a hauler design is illustrated with rotating beam handles 710 that extend outside of the hauler frame, similar to rotating beam handles 510 (FIGS. 5a and 5b). The hauler illustrated in FIG. 7 thus includes rotating beam handles 710, while not necessarily hanging side bags from them. The design in FIG. 7 can maximize a single cargo hold volume, yet provides the ease of folding, unfolding offered by the three cargo compartment designs, e.g., as shown in FIGS. 5a-5h.

[0051] Referring now to FIGS. 8a-8f, a two wheeled folding design for a hauler is illustrated. This design, as well as the single wheeled folding design, are configured to fold into a small stowed volume, suitable for being carried in a backpack, for example.

[0052] The wheels of the hauler illustrated in FIGS. 8a-8f are bolted to the interior rotating-translating beams 810 and use quick releases for the exterior or outside wheel beams 812. Handles 816 are illustrated that fold for compact stowage, and, as with other designs herein, handles 816 can telescope to extend or retract as desired. The hauler illustrated in FIGS. 8a-8f includes an aft cargo compartment, which can also fold to obtain a compact folded configuration. Three different cargo bags can be used with the hauler shown in FIGS. 8a-8f, one between hauling handles 816, another between the wheels and another in the aft cargo compartment.

[0053] Referring now to FIGS. 9a-9k, a single wheel hauler design is illustrated. The illustrated hauler design reduces fabrication expense by attaching two locking bent rotating beams 910 to the bent rectangular wheel frame structures 912 that support the wheel assembly. The curvature of bent rotating beams 910 permits the wheel assembly to store in-plane, so that when in use as a backpack, components do not protrude. Bent rotating beams 910 can lock or be secured with a securing mechanism such as a pin or bolt in a receiving opening in a deployed or unfolded configuration, as well as in a folded position. A benefit of attaching the hauling handles 914 to bent rotating beams 910 is that it increases the effective leverage of handles 914 to provide a moment. This moment provides better control and steerage.

[0054] The hauler illustrated in FIGS. 9a-9k includes cargo beams 916 that are stored in the bag support beams and can be pulled out forward and aft to permit cargo items to be hung from beams 916, or can be pushed back in to be stowed. Beams 916 can be locked in the stowed inner or pulled out orientations.

[0055] Single wheel designs, including that illustrated in FIGS. 9a-9k, are suitable for connecting to a waist belt and/or shoulder straps, as illustrated in FIGS. 2a-2c, such that the cart follows behind the person while walking or running. This configuration provides hands free hauling. The cart can also be operated as a wheel barrow, e.g., by permitting the user to grip handles 914 to control and transport the cart.

[0056] The single wheeled cart illustrated in FIGS. 9a-9k can be folded to a compact configuration suitable for, e.g., backpack transport. The cart is folded from a fully unfolded configuration by retracting telescoping hauling handles 914. Handles 914 may be rotated to align generally with bent rotating beams 910, as shown in FIG. 9f. The fore and aft extendable additional cargo beams 916 may be stowed by unlocking them from an is extended position and pushing them inward to a stowed position, as shown in FIG. 9f. The locking bent rotating beams 910 can be unlocked and pivoted downward to be stowed. As shown in FIG. 9h, the left bent rotating beam 910 can be unlocked and pivoted to be stowed before the right bent rotating beam 910 is unlocked from the unfolded position and stowed. It should be understood that the right and left rotating beams 910 can be configured to operate to be stowed or unfolded in any sequence or simultaneously. The cart in the stowed or folded configuration, as illustrated in FIGS. 9g, 9i and 9k, is compacted for easily being carried, such as by being attached to a shoulder harness or backpack for transport.

[0057] Referring now to FIGS. 10a-10g, a single wheeled foldable hauler is illustrated. The illustrated hauler has room for four compartments or bags for cargo, between handles 1014, on either side of the wheel, or in the aft cargo compartment. The wheel may be fastened to the frame with a fastener 1016 that includes a nylon washer 1018. Fastener 1016 may be a clevis pin. The frame of the hauler may be composed of sections that are welded together. The aft cargo compartment may be composed of a continuous bent component, as illustrated in FIGS. 10a-10f, or may be two separate, straight members that can fold more completely in the folded configuration, such as is illustrated in FIG. 10g.

[0058] Referring now to FIGS. 11a-11g, a single wheeled hauler design is illustrated. The hauler may be used for efficient back country cargo hauling over narrow or rough terrain. The design is narrowly tapered for light and efficient operation in back country conditions, such as may be the case for camping, hunting and other such applications. Cargo bags may be arranged in all four cargo areas. The arrangement of bags may be configured to minimize snags. For example, bags may be provided with hard bottoms that provide impact resistance for hauling over rough terrain. The hauler is configured in some examples to weigh about 11 pounds.

[0059] The wheel may be provided with a quick releases to permit the wheel to completely detach from the frame. This configuration reduces weight and provides for compact stowage, as illustrated in FIGS. 11d-11f. In the stowed configuration, the wheel is removed from the hauler using the quick release, which may be the same type of release often used for removing wheels from bicycles. The wheel is than placed within the folded hauler, with handles 1114 and extensions 1116 folded over the wheel, as illustrated in FIG. 11e, for example, to secure the wheel for backpack, shoulder strap transport.

[0060] In addition to accessories for attachment to bikes and ATV's, the backwoods hauler can also be configured with skis for cross country or downhill skiers. The frames of the hauler attach at the wheel for low center of gravity. A design variation for the hauler illustrated in FIGS. 11a-11g, as well as that shown in FIGS. 10a-10g, is to arrange the frame at a higher location relative to the wheel, which may, for example, provide greater clearance for cargo.

[0061] Another application for the haulers described herein is as a wheeled transport for transporting humans or animals. The hauler can be adapted to have a seat rather than or in addition to a cargo area, or can be provided with a stretcher type structure that can suspend a canvas sheet, for example, for a person or animal to lay on for transport. As an example, the hauler illustrated in FIGS. 8a-8f or that illustrated in FIGS. 9a-9k can be modified to have an extendable platform that permits suspension of a fabric on which a body can be laid to be transported. Such a hauler design would be particularly useful to evacuate injured persons in back country terrain, where the hauler could be transported by backpack by rescue personnel, and deployed or unfolded to provide a wheeled or ski enabled stretcher that could be used to evacuate an injured person.

[0062] The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various procedures or components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and that various steps may be added, omitted, or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims.

[0063] Specific details are given in the description to provide a thorough understanding of example configurations (including implementations). However, configurations may be practiced without these specific details. For example, well-known processes, structures, and techniques have been shown without unnecessary detail to avoid obscuring the configurations. This description provides example configurations only, and does not limit the scope, applicability, or configurations of the claims. Rather, the preceding description of the configurations provides a description for implementing described techniques. Various changes may be made in the function and arrangement of elements without departing from the spirit or scope of the disclosure.

[0064] Also, configurations may be described as a process that is depicted as a flow diagram or block diagram. Although each may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be rearranged. A process may have additional stages or functions not included in the figure.

[0065] Having described several example configurations, various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the disclosure. For example, the above elements may be components of a larger system, wherein other structures or processes may take precedence over or otherwise modify the application of the invention. Also, a number of operations may be undertaken before, during, or after the above elements are considered. Accordingly, the above description does not bound the scope of the claims.
