DETAILED DESCRIPTION OF THE INVENTION
[0069] Referring now to the accompanying drawings and initially to
[0070] The frame 12 is an open, lightweight structure formed by a pair of laterally spaced-apart longitudinally-extending frame members 20 between which a triangular cart body 22 is centrally affixed and extends downwardly therefrom defining a lower enclosure 24 within the cart body 22. The powertrain 16 is housed within the enclosure 24 of the cart body 22 and basically comprises a motor 30, battery 32, and motor controller 34. The motor 30 is in the form of a motor and transaxle assembly contained within a common housing 36 and mounted within the lowermost region of the enclosure 24, with a pair of drive shafts 38 extending co-axially outwardly from opposite ends of the housing 36 and outwardly therefrom to opposite lateral sides of the cart body 22. The battery 32 and the motor controller 34 are contained in a common housing 35 mounted within the enclosure 24 of the cart body 22 adjacent the motor 30, with the motor controller 34 being operatively connected by cables 33 between the battery 32 and the motor 30 for controlling supply of motive power to the motor 30. In addition, one or more sealed storage compartments may be provided within the cart enclosure, such as representatively indicated at 54, to carry various smaller supplies, spare parts, tools, and the like.
[0071] Each wheel 14 comprises a central hub 40 about which is mounted an all-terrain high-flotation tire 42. The wheels 14 are affixed in coaxial relationship by mounting their respective hubs 40 to the laterally outward ends of the drive shafts 38 of the motor/transaxle assembly, thereby supporting the frame 12 substantially entirely above the axis of the wheels 14. The handle structure 18 comprises a first pair of laterally spaced-apart handles 26 attached to respective rearward ends of the frame members 20 and a second pair of laterally spaced-apart handles 5 attached to respective forward ends of the frame members 20, in perpendicular or orthogonal relationship to the axis of the wheels 14. A platform 44 is affixed to the frame members 20 adjacent the upper side of the cart body 22 for defining a payload supporting area thereabove on which may be transported any of various types of payloads, as representatively depicted by payload P.
[0072] A switch device, indicated overall at 46, is mounted on one of the rear handles 26 and is operatively connected by a cable 48 to the motor controller 34 for selective remote actuation and deactuation of the motor 30. As depicted in
[0073] The rearward handles 26 of the handle structure 18 are configured for manual grasping of the handles by a single human operator for steering movement of the cart 10 while simultaneously operating the motor controller 34 via the switch device 46. Either or both of the forward handles 28 may optionally be grasped by a second human operator to assist in maneuvering and guidance of the cart 10 during navigation, but no controls for powered operation of the cart are provided on or in proximity to the forward handles 28. Both sets of handles 26, 28 may be provided with a series of adjustment holes 26A, 28A, best seen in
[0074] The operation of the cart 10 may thus be understood. All of the structure of the cart 10, including particularly the frame 12, wheels 14, powertrain 16 and handle structure 18, is designed dimensionally and in configuration to facilitate manual navigation over diverse and varied terrains by a single human operator. More specifically, the cart 10 can be maneuvered manually, either under the drive power on the powertrain or solely under the manual power of the operator, over substantially any terrain over which the human operator can walk, crawl or swim, including in particular both ground surfaces of topographic terrains and underwater and other water-covered hydrographic terrains. In topographic terrains, the cart 10 is capable of powered or unpowered rolling movement under the guidance of an operator over paved and unpaved ambulatory land surfaces including natural surfaces such as fields, meadows, forests, woods, hills, mountains, rocks, unpaved trails, caves, caverns, tunnels, and other above ground and subterranean land surfaces, and man-made surfaces such as roads, paths, hallways, breezeways, step structures, staircases and other outdoor and indoor man-made surfaces. In such environments, the operator manually guides rolling movement of the cart 10 over the ground surface via the handles 26 while walking, running or even crawling behind the cart, with selective activation of the switch device 46 to assist with powered motivation of the cart 10 as needed.
[0075] Owing to the lightweight frame structure, the use of all-terrain high-flotation tires, and sealed powertrain components, the cart 10 is equally capable of partially and fully submerged powered or unpowered movement over water-covered hydrographic terrains including creek beds, stream beds, river beds, pond and lake beds, flooded areas, swamps and muddy regions, culverts, storm sewers, drains, gutters, ditches, aqueducts, sluiceways, causeways, spillways and other natural and man-made underwater surfaces. In such environments, the operator manually guides rolling movement of the cart 10 on the underwater surface from behind the cart via the handles 26 while walking over or wading through areas covered with relatively shallow depths of water, or even floating or paddling behind the cart through areas covered with deeper depths of water. Even in areas with water depths above the height of an operator, the cart 10 is capable of rolling navigation over the underwater surface, although the operator may need underwater breathing apparatus depending on the underwater distance to be traveled.
[0076] Persons skilled in the art will recognize and understand that various additional and alternative features and embodiments of the cart are possible within the scope of the invention. For example, the cart could be equipped with continuous track mechanisms instead of wheels, such as representatively depicted at 55 in
[0077] Alternatively, in wheeled embodiments of the cart, each of the wheels could be equipped with an individual hub-mounted motor, such as depicted at 56 in
[0078] As will also be understood, the payload platform in the embodiments of the figures are merely representative. Various configurations of supports for carrying payload may be affixed to the frame instead of, interchangable with or in addition to a platform configuration, including for example but without limitation open and enclosed cargo boxes, a litter for carrying injured or wounded personnel, and any number of other purpose-built payload carriers designed for specific cargo applications.
[0079] Likewise, differing forms of handle structures are also contemplated. For example, a U-shaped or other handle structure transversely spanning between the frame members could offer the advantage of allowing an operator to actuate and deactuate the powertrain and guide navigation of the cart via different hand positions or possibly with only one hand.
[0080] While the cart of the present invention is not intended to float nor otherwise to be operable on the surface of a body of water, the cart could be equipped with supplemental flotation units to partially offset the weight of the cart and payload so as to allow the wheels, tracks, or other transport propulsion members of the cart to remain engaged with underwater and other water-covered hydrographic terrains but would aid in preventing the transport propulsion members from sinking into soft underwater surfaces, such as under ponds, streams and the like.
[0081] The advantages of the cart 10 for tactical uses by military, law enforcement, fire, rescue and emergency personnel will therefore be appreciated and understood. Fundamentally, the cart of the present invention combines into a single unit the capabilities of various other existing known transport devices. Further, the capability of the cart to navigate over virtually any topographic or hydrographic terrain expands the potential applications and uses of the cart enormously. The ability for a single operator to navigate the cart over such terrains further expands the applications for the cart. In a military setting, soldiers can transport weapons, munitions, equipment, food, water, and the like into battle settings in greater quantities, more rapidly and with less effort than any known conventional means. Law enforcement, fire, rescue and emergency personnel are similarly benefited by an ability to transport gear more quickly and easily into remote areas accessible only by foot.
[0082]
[0083] Payload platform 44 is configurable and accepting of a variety of attachments for securing diverse loads or load carrying devices. Examples of attachments include, but are not limited to, standard medical transport litters secured or attached such as through a clamp type mechanism or other mechanism, securing weapons platforms for operational use or transport in a tactical environment, supply material including ammunition, water, fuel, food, medical supplies, communication gear, collapsed shelters, watercraft, gas cylinders, generators, power supplies, clothing, or any other material needs of an end user or cart operator. Other attachment points, hooks, clamps, and tie straps on the cart can be used independent of payload platform 44 or a multifunctional attachment point to enable hoisting or anchoring of the cart or other desired movement. The same attachment points can also enable securing of payload P.
[0084] The attachment is attachable to the tactical transport cart at one or more attachment points, typically in the vicinity of the payload supporting area. There are also various possible types of attachments within the scope of the present invention.

[0105] With the features of modularity, configuration options, and the employment of diverse electrical components and power systems, the cart can be modified in such a manner to accommodate robotic or autonomous systems. Thus, the cart of the present invention is operated with or without a person. This is accomplished by use of wireless or wired operation of the cart, cart teaming, or other methods of control in which conventional operation is not required. The port can be used to connect a receiving device that receives a wireless signal from a remote control or other control device. Thus, the port can be used for signals as well as for power.
[0106]
[0107]
[0108] An auxiliary power pack 93 can be used to serve as a supplemental power pack and alternative power supply for the cart. Located external of the primary power pack or supply, the auxiliary power pack or supply when utilized can serve the purposes of extending operating range of the cart due to increased energy availability, serving as backup power supply in the event of power failure or depletion of the primary power supply, and charging the primary power supply. The auxiliary power pack can be rapidly inserted into the electrical enclosure that houses the primary power supply, referred to as a swap. The auxiliary power pack can be connected to and power the cart even when there exists no primary power supply within the electrical enclosure. The auxiliary power pack can be used independent of primary function to charge or power other items requiring power not on the cart or payload on the cart that has a power requirement.
[0109]
[0110] By virtue of being towed, downhill motion without motive power, pushed, or similar movement, regenerative braking energizes the battery or other connected devices.
[0111] It will therefore be readily understood by those persons skilled in the art that the present invention is susceptible of a broad utility and application. Many embodiments and adaptations of the present invention other than those herein described, as well as many variations, modifications and equivalent arrangements will be apparent from or reasonably suggested by the present invention and the foregoing description thereof, without departing from the substance or scope of the present invention. Accordingly, while the present invention has been described herein in detail in relation to its preferred embodiment, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for purposes of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended or to be construed to limit the present invention or otherwise to exclude any such other embodiment, adaptations, variations, modifications and equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof.
