Also, the terminology used herein is for the purpose of description and not of limitation.
In various exemplary embodiments, the technology described herein provides a self-contained mobile vending apparatus, such as a portable vending trailer. The self-contained mobile vending apparatus is configured to hold and transport vending equipment and machines, to provide vending services to patrons, and to provide power to the vending equipment with one or more interchangeable power sources including both traditional and alternative power sources. The self-contained mobile vending apparatus is configured for easy transportability and fast and easy set-up.
The self-contained mobile vending apparatus is adapted with online connectivity to provide, for example, inventory updates via the internet, or other like network or communications access, with 24/7 remote accessibility. As such, the self-contained mobile vending apparatus is adapted for remote monitoring, inventory management, safety checks, alarms, security, temperature controls, closed circuit cameras, and so forth.
By way of example, the self-contained mobile vending apparatus is useful in remote locations, which have no traditional power source, such as county or state fairgrounds, craft shows, festivals, the desert, parks, athletic events, parking lots, and the like.
By utilizing power from alternative power sources, such as solar and wind power, the mobile vending trailer provides a novel solution to powering portable vending machines that is environmentally sound. Although the mobile vending apparatus preferably is powered by alternative power sources, such as electricity generated by solar power and wind power, the mobile vending apparatus also is capable of coupling to the existing power grid and to various types of electrical generators. The mobile vending apparatus is adapted for use both off-grid and on-grid.
When the mobile vending trailer is used on-grid, a grid-tie inverter is utilized to feed a net outflow of power into the utility grid. As such, as wind and solar power is harnessed to charge batteries and power the vending machines, excess power is fed back into the utility grid. In many locales, individuals and businesses are permitted to sell their energy to the utility grid under a net metering policy. For the owner of the mobile vending trailer, this can further reduce or offset the costs of operation.
The mobile vending apparatus is designed to accommodate one or more vending machines of various products and food and beverage items, such as, for example, beverages, sundries, industrial supplies, toys, lotions, clothing, gifts, gift cards, electronics, novelty items, and so forth. The mobile vending apparatus is available in varied sizes based on the number of vending machines stored within the kiosk and the specific application and desired locations of the mobile vending apparatus. The mobile vending apparatus is configured for storage of additional product, which is yet to be placed within a vending machine, within the housing of the vending apparatus.
Referring now to the Figures, a mobile vending apparatus 10 is shown. The mobile vending apparatus is fully self-contained. In various embodiments, the mobile vending apparatus 10 is solar-powered, wind-powered, AC powered, generator-powered, or powered by any interchangeable combination and/or use of one or more of the above power sources. This provides multifaceted use of the mobile vending apparatus 10 in a variety of scenarios of traditional power availability/unavailability and the availability of alternative sources such as wind and solar.
The mobile vending apparatus 10 includes a portable chassis 20. The portable chassis 20 provides the mobile vending apparatus 10 a means by which vending machines 16 can be transported. The portable chassis 20 includes a tongue for attachment to a truck or other vehicle adapted to pull the mobile vending apparatus 10. The tongue is removable when the mobile vending apparatus 10 is in use. This enables the mobile vending apparatus 10 to resemble a stationary vending stand, or the like, rather than a traditional trailer. In at least one embodiment, the mobile vending apparatus 10 and the portable chassis 20 is a trailer. In at least one alternative embodiment, the mobile vending apparatus 10 and the portable chassis 20 is a truck. As will be apparent to one of ordinary skill in the art, upon reading this disclosure, the mobile vending apparatus can vary in use in terms of mobile versions, such as a trailer and truck, and temporarily stationary versions, such as a trailer with the tongue removed and made more lasting and stationary for a longer even, fair, or the like.
At least one embodiment of the portable chassis 20 includes at least two wheels 36 disposed upon opposing ends of a common axle 38. As such, and as depicted specifically in FIG. 6, wheels 36 are coupled to the common axle 38. This embodiment of the portable chassis 20 utilizes a primary frame/beam member 40.
The portable chassis 20 of the mobile vending trailer 10 also includes an axle support frame 34. The axle support frame 34 is configured for retractability such that, for example, the housing 18 can be lowered to a desired level, such as to a ground level surface. Additionally, the axle support frame 34 is configured for extendibility to raise the housing 18 to a desired level, such as level with a platform.
As depicted specifically in FIG. 6, the axle support frame 34 can be retracted and extended. A primary frame/beam member 40, generally upright, vertical, and perpendicular to the wheel axle is utilized with a vertical screw jack (not shown). As the vertical screw jack is actuated and rotated either clockwise or counter-clockwise, an axle slot beam yoke either is lowered or raised, respectively, through the primary frame/beam member. As such the entire housing 18 and the various vending machines 16 contained within, are lowered and/or raised to a desired level for use by patrons.
By way of example, and not of limitation, the axle support frame 34 is retracted thirty inches to lower the housing 18 to a ground level surface, such as when the mobile vending trailer 10 is used at a fairground. Also, by way of example, the housing 18 can be raised, after use at ground level, to a height of approximately eleven inches above a ground level for use at a travel height of the mobile vending trailer 10. Leveling jacks 44 can be utilized when the housing is not at ground level.
In at least one embodiment, the axle slot beam yoke 42 utilizes pins to secure to the housing 18 of the mobile vending apparatus 10. The housing 18, and the various vending machines 16 contained within the housing 18, which are accessible to those outside of the housing 18 of the mobile vending apparatus 10, is operably lowered and raised as needed to provide a ground level, a raised level, or the like, accessibility to a user of the vending machines 16.
Alternatively, and as depicted in FIGS. 12-16, a portable chassis 20 with a straight axle design is utilized in at least one embodiment to enable the housing 18 to be lowered to the ground. In this embodiment, the portable chassis 20 includes a straight axle assembly in the portable chassis 20.
The portable chassis 20 includes at least one lift assembly 46 disposed within the portable chassis 20 and configured to lower the housing 18, in entirety, from a first level to a second level and to raise the housing 18 from the second level to the first level.

As depicted in FIGS. 14, 15, and 16, respectively, the housing 18 is shown in a raised position, in transit being lowered, and at ground level, as raised and lowered by the lift assemblies 46. As such the entire housing 18 and the various vending machines 16 contained within, are lowered and/or raised to a desired level by the lift assemblies 46 for use by patrons. The portable chassis 20 can be used with or without leveling jacks 44. Additionally, the tongue of the portable chassis 20 can be removed when the housing 18 is in use at ground level.
In use, the lift assemblies 46 on the portable chassis 20 provide a means to operatively lower and raise the entire housing 18 containing the vending machines 16. This is suitable for locations wherein it is desired to place the vending machines 16 at ground level. This also is suitable for locations wherein it is desired to maintain the vending machines 16 at a predetermined height above ground level.
In various embodiments, other combinations in the number of wheels 36 and the number of wheel axles are used. By way of example, larger implementations can include four wheels. Additionally, the portable chassis 20 embodiments include common and straight axle versions.
The mobile vending apparatus 10 includes a housing 18 disposed upon the portable chassis 20. The housing 18 can be of any size, shape, or design, such that is travels securely upon the portable chassis 20. The housing 18 is durable and is suitable for transit on known transportation networks. As depicted in the Figures, the housing 18 resembles the shape of a beverage or cola can. As will be apparent to one of ordinary skill in the art, upon reading this disclosure, alternative shapes and designs for the housing 18 can be utilized. The housing 18 can be leveled using leveling jacks 44, as depicted in FIG. 1, to ensure that the housing 18 is stable when in use at a desired location.
The mobile vending apparatus 10 includes a solar panel array 12. The solar panel array 12 includes multiple solar panels. The solar panels are mounted to the top of the housing 18 such that they can be moved to obtain a better angle to the sun. As depicted, there are six solar panels in the solar panel array 12. However, the number and placement of the solar panels in the solar panel array 12 can be varied in order to optimize the capture of sunlight or for manufacturing considerations. By way of example, and not of limitation, a thirty-two foot trailer can be configured with enough solar panels to provide up to 2500 kW per month. The solar panel array 12 is configured to capture sunlight and convert the captured sunlight into electricity, thereby to provide solar power to charge the bank of batteries 28 and to charge the vending machines 16.
In various embodiments, the solar panel array 12 is used to power the vending machines 16, or alternatively, to charge the batteries 28, which can power the vending machines 16 even when solar power is unavailable. By way of example, when fully charged, the batteries 28 are numerous enough and are configured to provide power the mobile vending trailer 10 and the vending machines 16 for at least three days when no additional power is generated from the solar panel array 12.
In at least one embodiment, the mobile vending apparatus 10 includes a wind turbine 14. The wind turbine 14 is of a size suitable for mount to a mobile unit such as the mobile vending apparatus 10. The wind turbine 14 can includes blades pushed by wind, as depicted, or any other means to capture wind and transfer the power. A mast 26 is utilized in at least one embodiment to provide height to the wind turbine 14. The mast is of sufficient height to insure safety in operation of the wind turbine 14. Additionally, in at least one embodiment, the mast 26 is telescopic and extensible. The wind turbine 14 is configured to extract energy from the wind to create wind power, thereby to provide wind power to the bank of batteries 28 and to the vending machine 16.
In various embodiments, the wind turbine 14 is used to power the vending machines 16, or alternatively, to charge batteries 28, which can power the vending machines 16 even when wind power is unavailable. Preferably, the batteries 28 are configured to have a three-day charge, such that if no wind power, or other power source, is available, the batteries 28 can provide power to the vending machines 16 for this extended amount of time.
The mobile vending apparatus 10 includes a grid tie inverter 48. The grid-tie inverter 48 is configured to feed a net outflow of power into the utility grid when the mobile vending apparatus 10 is on-grid. The grid-tie inverter 48 is a type of inverter used in alternative power systems, such as those for renewable energy, to convert direct current into alternating current and feed it into the utility grid.
