Description:
BACKGROUND OF INVENTION 
     Field of Invention 
     The present invention is related to new and improved trailer jack and transport systems and related equipment, adapted for mounting to sport, recreational and/or utility trailers designed to carry and transport personal water crafts (PWCs), boats, mobile vehicles such as motorcycles and all-terrain vehicles (ATVs), recreational and camping shelters, and portable utility equipment such as power generators, air compressors and pumping systems, transportable over solid surfaces such as concrete and asphalt, over soft surfaces such as sandy beaches and dirt roads, and within shallow muddy waters along beaches and coastal areas. 
     Brief Description of the State of the Art 
     Trailer jack and transport systems are well known in the art, and are currently provided (e.g. mounted) on the tow end or portion of sport, recreational and utility trailers designed to carry and transport personal watercrafts (PWCs), boats, mobile vehicles such as motorcycles and all-terrain vehicles (ATVs), recreational and camping shelters, and portable utility equipment such as power generators and pumping systems, capable of supporting a stationary trailer or transport over solid surfaces such as concrete and asphalt, as well as soft surfaces such as sandy beaches, dirt roads, and shallow muddy waters along beaches or coastal areas. 
     In general, most conventional wheeled trailer jack and transport systems employ an extendable jacking post member that is rotatably mounted to the trailer’s central tow beam or framework. The extendable jacking post member is terminated with one or more caster-type wheels for enabling rolling action of the supported trailer during transport along a desired direction. Trailer jacks may also be terminated with a stationary foot for supporting the trailer in a fixed position. Typically, during trailer jacking operations, the extendable jacking post member is extendable by turning a hand-crank provided on the caster-wheel trailer jack and transport system. 
     The raising and lowering of the wheeled jack adjusts the height of a trailer’s tongue, allowing for, among other purposes, the trailer coupler to be lifted above the ball of a trailer hitch, typically on a motor vehicle, and lowered onto the ball of the trailer hitch. The caster wheel offers a method of positioning the trailer coupler over the hitch through manually pushing, pulling, and steering of the trailer assembly. Trailer jacks may also include a means of rotating into a storage position on the trailer to which the trailer jack is fastened. This non-functioning position allows for the coupled motor vehicle and trailer to operate as a physically connected system without interference by the trailer jack wheel on the rolling surface. 
     Prior art trailer jacks, as they are often called, are available in a variety of sizes capable of carrying varying loads depending on the load capacity of the trailer to which it is affixed. For example: 500-pound,  1 ,000-pound or 2,000-pound capacities. Similarly, conventional wheeled trailer jacks also utilize a variety of wheel sizes, both in diameter and width, to accommodate load and offer motion over varied terrain. Common wheel diameters range from 6″ to 8″ with wheel widths ranging from 1″ to 2.5″. Some casters include two wheels side-by-side, offering better support on gravel or loose ground surfaces where trailers are often used. Trailer jacks can be welded onto trailers or bolted in place. 
     Prior art caster-style wheels such as those employed on wheeled trailer jacks utilize two axes of rotation to accomplish steerable movement. A first axis is provided about which the wheel rotates (namely the axle, or X-axis,) and a second axis is provided about which the wheel assembly consisting of forks, wheel, axle, and mechanical fasteners rotate to accomplish steering (the longitudinal or Y-axis)). The two axes are offset by design, allowing a caster wheel to “swing” into the intended direction of travel as the trailer is manually moved. A disadvantage of this type of arrangement occurs when starting from a standstill, particularly when the desired travel distance of the trailer is short. While bearing the weight of the trailer (and often its contents), it is often difficult to turn the caster wheel(s) toward an intended target (e.g. a trailer hitch) while the trailer and wheeled jack assembly are not in motion. It is improbable to have “pre-set” the direction of travel when the trailer jack wheel was previously lowered onto the ground as the desired direction of travel of the trailer assembly is not known until its target (typically a motor vehicle’s trailer hitch) has returned and later positioned in close proximity to the trailer coupler. 
     When coupling or de-coupling a trailer from a motor vehicle, it is desirable for the action to be as easy, quick, and safe as possible. Coupling or de-coupling a trailer is a critical but small preparation step of a larger goal: to transport goods (a boat, personal watercraft, snowmobile, lawn mower, furniture, camper, air compressor or any other equipment that does not contain its own terrestrial propulsion) over the road to a new destination (e.g. a boat launch, a beach, a trail, a worksite, a storage facility, a campsite, etc.). Users desire to spend as little time as needed on preparation. When a caster wheel is not rotated into the desired direction of travel, it takes time and energy to reposition the wheel through “banging” on the wheel, jockeying an entire trailer assembly, or through unwanted and unnecessary additional rolling travel. Some caster-style trailer jacks employ a larger distance between its steering axis (Y-axis) and its axle. Such a configuration offers smoother straight-line travel but requires a larger turning circle. Short X-to-Y axis caster styles exhibit shorter turning circles but can result in erratic straight-line travel as the caster is more prone to “wobbling” about the steering axis. 
     Prior art type caster-style wheeled trailer jacks, as disclosed in U.S. Pat. No. 6,439,545 to Hansen can be easily damaged or broken when excessive force is exerted onto the caster wheel assembly by a user pushing the trailer tongue in a direction for which its two-axis system is not properly positioned. Plastic wheels can break, wheel bearings can be damaged, and a jack’s typically metal-and-welded components can bend or break. Pushing a wheeled trailer-jack-enabled trailer whose caster is not properly positioned can also result in damage to the trailer hitch-equipped motor vehicle. Once in motion, a caster-style wheeled jack continues in the direction the wheel is pointed unless and until sufficient lateral force is applied to the rolling trailer to cause the caster to rotate about its second axis. The momentum of a trailer equipped with a caster-style wheeled trailer jack, particularly when carrying a load, can be difficult to overcome. When traveling toward a vehicle, this can result in a collision, causing cosmetic damage to the vehicle. Worse yet, the user can get caught between the trailer and the motor vehicle, causing bodily injury. 
     Narrow traditional wheels have less rolling resistance and are therefore easier to get moving and keep in motion when used on a wheeled trailer jack. The disadvantage to narrow wheels carrying weight is their tendency to sink into soft ground surfaces which are common to many trailer applications, namely non-paved surfaces like sand, gravel, grass, snow, or dirt, rendering the wheel inoperable. Wider conventional wheels and dual wheel configurations have been developed to minimize this disadvantage; but such wider configurations are more difficult to directionally steer. 
     While improvements have been made with regard to manual trailer jacks and transport systems, there has also been an increased demand for remote controlled powered tractor-type trailer transport systems such as the Trailer Valet RVR series by Supertech S. Corp.. While this system allows virtually anyone to transport trailers of many weights and sizes and offers great convenience when needing to transport trailers without a motor vehicle, it suffers from shortcomings and drawbacks such as in-place storage modes and easy-rolling manual 360-degree freewheel operation as situations may require. Consequently, prior art remote-controlled self-powered trailer transport systems fail to fulfill the diverse needs of the growing recreational vehicle (RV) industry, and the marketplace is clearly searching new and improved technologies that will increase convenient and safety. 
     Accordingly, there is a great need in the art for new and improved trailer jack and transport systems that provide improved steerable rolling motion to sport, recreational and utility trailers, when operating on diverse kinds of ground surfaces, including pavement, dirt, sand, and mud, without the use of caster-style wheels, while avoiding the shortcomings and drawbacks of the prior art apparatus and methodologies.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE PRESENT INVENTION 
     Referring to the figures in the accompanying Drawings, the illustrative embodiments of the system will be described in great detail, wherein like elements will be indicated using like reference numerals. 
     As a primary object of the present invention, each of the illustrative embodiments of the trailer jack and transport system of the present invention  1  is equipped with a load-bearing spherical object  101  such as a load-bearing spherical transport ball that provides and supports improved rolling and steerable motion to sport, recreational and utility trailers  5 , when operating on diverse kinds of ground surfaces  90 , including pavement, dirt, sand and mud, without the use of caster-style wheels. 
     Functioning as a wheeling device, the load-bearing spherical transport ball  101  is supported within a framework assembly  103 , preferably having a spherical or other suitable geometry, and configured to allow the spherical wheel to freely rotate with 360 degrees of freedom, in any orientation on bearing surfaces  102  of a diverse nature, that may come in contact with and engage a portion of the spherical wheel during system operation. 
     As illustrated in  FIG.  2 A , the load-bearing spherical transport ball  101  has infinite number of virtual axes of rotation passing through a single virtual centroid  141  located and embedded within the center of the spherical ball  101  about which all motion is accomplished - both directional and rotational. 
     In one preferred embodiment, the height-adjusting jack assembly  12  is centered above the spherical wheel  101 , providing 360-degree direction of travel. In another illustrative embodiment, the height-adjusting jack assembly  12  is offset from the center of the spherical wheel  101 , reducing the complexities of rotating the wheeled jack into a storage position. 
     By virtue of its design, the spherical wheel assembly  10  creates the opportunity to drive the wheel through battery-powered means for maximum convenience. 
     By virtue of its design, the spherical load-bearing transport ball (e.g., spherical wheel)  101  distributes an associated tongue weight of the trailer  5  over an increasingly larger area when the ground surface  90  is soft, providing defense over gravel, sand, snow, grass, dirt and mud. 
     These and other features and benefits of the present invention will become more apparent hereinafter and in the Claims. 
     Before specifying the technical details of each illustrative embodiment of the trailer jack and transport system of the present invention, it will be helpful to provide an overview of a primary use case or end-user application for the system. Additional end-user applications for the trailer jack and transport system of the present invention, shown across different fields of human activity and recreational, commercial, and industrial (including military) activity over varied terrain can be found in  FIGS.  40  through  45   .

       FIG.  17    describes the primary steps involved in the method of operating the powered trailer jack and transport system with onboard controls  45  mounted to a trailer according to the principles of the present invention. 
     As shown in  FIG.  17   , the system user starts at Block A and progresses to Block B and powers on the remote controller unit  424 . 
     At Block C, the user controls powered transport of the trailer with the onboard joystick controller  424 B. 
     At Block D, the user controls trailer jacking (i.e., raising and lowering relative to ground surface) with the jacking toggle switch  424 C on the remote controller  424 . 
     At Block E, control signals are communicated to the control and communications unit (CCU)  425  via the controller wiring  425 K illustrated in  FIG.  16   . 
     At Block F, the controller determines whether or not the CCU has received an input signal from the joystick directional controller. If yes, the control process proceeds to Block G, and if not, the control process flow proceeds to Block L. 
     At Block G, the CCU microprocessor  425 E receives input from joystick directional controller. 
     At Block H, the CCU microprocessor  425 E processes directional information from joystick directional controller. 
     At Block I, the CCU microprocessor  425 E sends directional information to position controller  425 H. 
     At Block J, rotational speed information and power are transmitted to the KIWI drive motors  407 - 1 ,  407 - 2  and  407 - 3 . 
     At Block K, the drive motors  407 - 1 ,  407 - 2  and  407 - 3  power and drive rotational motion of the transport ball through interaction of drive rotors  407 C- 1 ,  407 C- 2  and  407 C- 3  and the surface of the spherical wheel  101  so as to enable transport of the system under the control of the user operator. 
     At Block L, if the CCU has received an input signal from the jacking control toggle switch  424 C then at Block M these input signals are received by the CCU microprocessor from the jacking control toggle switch  424 C 
     At Block N, the CCU microprocessor processes the directional information from the jacking control toggle switch  424 C 
     At Block O, the CCU microprocessor sends rotational direction information to the jack motor  425 B 
     At Block P, the driven jack motor  425 B raises or lowers the spherical wheel shaft (i.e., inner jacking post member)  121  through interaction of the gears  425 C with the telescoping jacking post members  422  and  121 , for use during hitching and other trailer related functions such as raising the front section of the trailer to allow water runoff of the trailer or its contents. 
     If at Block L, the CCU  425  has not received an input signal from the jacking control toggle switch  424 C, then at Block Q, the powered trailer jack and transport system  4  remains stationary relative to the ground surface. 
     At Block R, the CCU microcontroller  425 E determines whether or not power has been on without control signals received by the CCU, for more than the pre-configured time period. If power has not been supplied to the system without input control signal within the prespecified time period, then the control flow returns to Block F, where the controller determines whether or not the CCU has received an input signal from the joystick directional controller. 
     At Block S, if power has been supplied to the system without input control signal (i.e., no user input has been detected when the system has been activated), then the powered trailer jack and transport system  4  is automatically deactivated (i.e., power is turned off) within the CCU module  425 .

     At Block G, the mobile app  427 AA prompts user to select “generate parking path”. 
     At Block H, the user tows trailer  53  forward with tow vehicle  9 . 
     At Block I, the wireless control and communications unit (CCU)  425 ‴ continually processes GPS and RTK positioning signals of the CCU and navigator beacon and stores positioning information in non-volatile memory  425 E‴ in the CCU and the cloud servers  430 , with logical addresses. 
     At Block J, the driver of tow vehicle  9  determines whether or not the trailer  53  completely clear of its home parking position and every obstacle in its egress path.

     At Block N, the user names the sequence for later retrieval. 
     At Block O, the store function is complete; and battery-powered assemblies of the automated trailer jack and transport system  4 ′ are powered down. 
     By virtue of the method of the present invention, it is now possible for the system to automatically learn, capture and store/remember the GPS coordinates of a trailer’s parking path, including a parking boundary  442  and the opposite end of the path at T(x), and other parking locations where the trailer  53  may be parked by a human driver. These GPS coordinates specifying the geometrical boundaries of each spatial region where the trailer  53  can or may be stored along its journey, can be stored in cloud-based servers  430 , and/or local memory of an automated trailer jack and transport system  4 ‴. Subsequently, when operating in an automated parking mode, these GPS-specified trailer parking boundary coordinates stored on cloud servers  430  or locally can be quickly accessed and used by the cloud system  430  and/or transport system  4 ‴ to automatically guide and transport the trailer  53 , via transport system  4 ‴, safely to its intended registered parking location  442  without the use of a human driver, thereby advancing the state of the art in cloud-based trailer parking automation.

     Specification of the Battery-Powered Remotely-Controlled (RC) Transportable System Equipped with Any Arrangement of Multiple Load-Bearing Transport Ball Constructions of the Present Invention Mounted Within a Framework Supporting Trailer Hitching Apparatus 
     Referring to  FIGS.  50 A and  50 C , there is shown another alternative embodiment of the present invention in the form of a battery-powered remotely-controlled (RC) transportable system  70  equipped with an arrangement of multiple load-bearing transport ball constructions of the present invention  40 - 1 ,  40 - 2 , and  40 - 3 , mounted within a framework or chassis  701  and integrated within a computer-based control system, supported by battery power storage module and control electronics  725  for supporting trailer hitching apparatus  8  and its various jacking, transport and navigation functions described hereinabove, in connection with a trailer  53 . 
     As shown, the battery-powered remotely-controlled (RC) transport system  49  comprises: f a dual-axle boat trailer  53  operably coupled to a remotely controlled powered (i.e., motorized) transport system  70  being controlled by a human operator remotely controlling the direction of powered motion of the transport system and hitched trailer via a Bluetooth wireless connection  500  from a mobile phone  427 ′ equipped with a suitable mobile app  427 AA. 
     As shown, the remote-controlled (RC) powered transport system  70  utilizes a configuration of multiple load-bearing spherical wheel assemblies of the present invention  40 - 1 ,  40 - 2  and  40 - 3 , mounted on a strong chassis  701  for mounting and supporting the spherical wheel assemblies, and preferably supporting a common battery storage cell and control and navigation electronics  725  illustrated in the system diagrams of  FIG.  20    and/or  27 , both of which are incorporated herein by reference to this illustrative embodiment. Its jacking post  8  is centrally mounted within the central portion of the chassis  701 , with a trailer ball at its top, and may include automated/powered hydraulics or linear motors, to enable the automated raising and lowering of the hitching post  8  as required to couple up with its target trailer  53 . Preferably, this function will be remotely controlled using the mobile app  427 AA along with trailer transport and navigation function of the present invention, disclosed herein. 
     In  FIG.  50 B , the system  70  is shown arranged and hitched to a trailer  53 , or other recreational or work vehicle, is being remotely controlled by a user using a mobile phone  427 ′ running associated mobile app  427 AA configured for supporting navigation, (optionally jacking) and transport functions in accordance with the principles of the present invention, on a ground surface  90  that may be hard (e.g., concrete, asphalt, wooden, etc.) as well as rough and soft (e.g. lawns, dirt paths, and sandy ground surfaces such as beaches, etc.). 
       FIG.  50 C  shows the battery-powered remotely-controlled transport system  70  comprising: a rugged weight/load-bearing frame/chassis  701  supported and driven by three battery-motor powered spherical wheel assemblies  40 - 1 ,  40 - 2 , and  40 - 3 ; a trailer hitch and ball  8 ; and a battery-powered control and communications unit  725  electrically connected to and driving the electric-drive motors  407  employed in the powered spherical wheel assemblies  40 , adapted for pulling and transporting (i.e. trucking) a trailer  53  equipped with a coupler, without the use of a traditional motor vehicle. 
     As shown, the system  70  supports all of the automated navigation and transport functions of all other power system embodiments described herein using a single powered spherical wheel assembly of the present invention, but just performs such function using a cluster of spherical wheel assemblies to support great trailer loads and great pulling power required by the application at hand. Powered spherical wheel clusters, comprising two, three, four or more powered spherical wheel assemblies of the present invention, may be configured and deployed about any kind of framework structure such as  701 , to suit and support the trailer trucking and transport application at hand. The chassis framework  70 , made from welded metal materials, or composite materials having high strength for the application at hand, may be realized as a standalone unit as shown in  FIG.  50 C , or the chassis framework  70  may also be mounted to the trailer frame  53  and support both transport and storage modes of configuration and operation, as described in the single battery-powered spherical wheel assembly embodiments of the present invention, specified in great technical detail hereinabove. 
     It is understood that the battery-powered remotely-controlled transport system  70  may be integrated within the A-type or other frame portion of a trailer framework, and adapted for retraction within the trailer frame or body during the storage mode as taught in  FIGS.  14 A through  14 D , and protracted from the trailer body during the transport mode of operation when configured and operation in such a manner. 
     Also instead of using a mobile phone and mobile app to remotely control the battery-powered remotely-controlled transport system  70 , it is understood that the system can be adapted to support the use of an integrated remote control unit such as RC unit  424  shown in  FIGS.  18 J,  19 A and  19 B , or RC unit  424 ′ shown in  FIG.  22   , which may be used to also remotely control the trailer jacking, transport and navigation functions as described in detail herein. Such variations and modifications will readily occur to those skilled in the art having the benefit of the present invention disclosure. 
     When using multiple spherical wheel assemblies  40  to design, construct and operate a manually powered (i.e. push powered) transport system, a mechanically-powered transport system (e.g. using a gear-drive mechanism driven battery-powered motor or drill) or a battery-powered motor driven transport system, the RC function can be provided and offer great benefits and advantages to the user in terms of convenience and safety. Such multi-spherical wheel supported transport systems  70  and variations thereof, can also provide interconnected and in communication with the cloud-based servers and services illustrated in  FIGS.  26 A,  27 ,  30 A, and  36   , to provide GPS-guided navigation capabilities to system  70 , as well as LIDAR-based environmental awareness. 
     In general, the system networks described in  FIGS.  26 A,  27 ,  30 A, and  36   , and which are used to practice the various embodiments of the present invention disclosure herein, comprise various system components, including: a cellular phone and SMS messaging systems; and one or more industrial-strength data centers, preferably mirrored with each other and running Border Gateway Protocol (BGP) between its router gateways, in a manner well known in the data center art. In  FIGS.  26 A,  27 ,  30 A, and  36   , and other illustrative embodiments, each data center typically comprises: a cluster of communication servers for supporting http and other TCP/IP based communication protocols on the Internet; cluster of application servers; a cluster of email processing servers; cluster of SMS servers; and a cluster of RDBMS servers configured within an distributed file storage and retrieval ecosystem/system, and interfaced around the TCP/IP infrastructure of the Internet well known in the art. For details regarding such system engineering considerations and requirements, reference should be made to U.S. Pat. Application Publication No. 20160197993, incorporated herein by reference in its entirety as if set forth fully herein. 
     As shown, the system network architecture also comprises: a plurality of Web-enabled mobile client machines  427  (e.g. mobile computers such as iPad, and other Internet-enabled computing devices with graphics display capabilities, etc.) running native mobile applications  427 AA and mobile web browser applications supported modules supporting client-side and server-side processes on the system network of the present invention; and numerous media servers (e.g. Google, Facebook, NOAA, etc.) operably connected to the infrastructure of the Internet. The network of mobile computing systems will run enterprise-level mobile application software, operably connected to the TCP/IP infrastructure of the Internet. Each mobile computing system is provided with GPS-tracking and having wireless internet connectivity with the TCP/IP infrastructure of the Internet, using various communication technologies (e.g. GSM, Bluetooth and other wireless networking protocols well known in the wireless communications arts). 
     In general, regardless of the method of implementation employed, the system network of the present invention will be in almost all instances, realized upon an industrial-strength, carrier-class Internet-based network of object-oriented system design. Also, the system network will be deployed over a global data packet-switched communication network comprising numerous computing systems and networking components, as shown. As such, the information networks of the present invention is often referred to herein as the “system” or “system network”. 
     Preferably, although not necessary, the system network of the present invention would be designed according to object-oriented systems engineering (OOSE) methods using UML-based modeling tools such as ROSE by Rational Software, Inc. using an industry-standard Rational Unified Process (RUP) or Enterprise Unified Process (EUP), both well known in the art. Implementation programming languages can include C, Objective C, C, Java, PHP, Python, Google’s GO, and other computer programming languages known in the art. The Internet-based system network can be implemented using any object-oriented integrated development environment (IDE) such as for example: the Java Platform, Enterprise Edition, or Java EE (formerly J2EE); Websphere IDE by IBM; Weblogic IDE by BEA; a non-Java IDE such as Microsoft’s .NET IDE; or other suitably configured development and deployment environment well known in the art. Preferably, the system network is deployed as a three-tier server architecture with a double-firewall, and appropriate network switching and routing technologies well known in the art. In some deployments, private/public/hybrid cloud service providers, such Amazon Web Services (AWS), may be used to deploy Kubernetes, an open-source software container/cluster management/orchestration system, for automating deployment, scaling, and management of containerized software applications, such as the mobile enterprise-level application described above. Such practices are well known in the computer programming, networking and digital communication arts.
