## Background
TECHNICAL FIELD
The present invention relates generally to outdoor amenities, and more specifically to portable recreation devices for use with motorized vehicles offering the convenient storage and transport of cooking, entertainment, refrigeration, and like accessories for outdoor use.
BACKGROUND OF THE INVENTION
During outdoor entertainment events, such as sporting contests, tailgate parties, fireworks, parades, picnics, and the like, it is often desirable to have many of the amenities used in one's home available for out-of-door purposes. In some public locations, limited facilities are provided for communal use, such as picnic tables, free standing grills, and restrooms. Unfortunately, these facilities are often times inconveniently located or already in use, if available at all in that particular location.
It is commonplace for spectators and patrons attending outdoor entertainment events to transport a variety of convenience and luxury items to the event site. For example, patrons of an outdoor entertainment event may erect temporary facilities for such activities as cooking, dining, sleeping, and the like. Such temporary facilities may include, by way of example, foldable chairs and tables, portable barbeques and other cooking appliances, umbrellas, and tents. It is also conventional to transport separate accessories for entertainment, refrigeration, and storage purposes. These accessories can include such items as electric coolers and ice boxes, power generators, stereo and other sound systems, televisions, etc.
Often, people are transported to these types of outdoor activities in a motor vehicle, such as a pickup truck, sport utility vehicle, conversion or minivan, or recreational vehicle. Accordingly, traditional methods of transporting the various outdoor convenience and luxury items noted above consist primarily of utilizing the motor vehicle in which the patrons themselves use to travel to the particular event. The most obvious course is to use the passenger and trunk compartments provided by the vehicle itself to transport these personal effects. However, this means of transport utilizes valuable space inside the vehicle that can be used to move more delicate items.
An alternative means of transporting the various outdoor convenience and luxury items noted above without using the passenger and trunk compartments of the vehicle is by means of a towable trailer that attaches to the rear of the vehicle body, generally to a trailer hitch. Conventional towable trailers generally comprise an open platform or square compartment with an access door, mounted to a two- or four-wheel chassis. The chassis, in turn, includes attaching means for securing the towable trailer to a trailer hitch—traditionally a cantilevered control arm. However, such devices can be costly, and may adversely affect the handling and safety of the towing vehicle.
SUMMARY OF THE INVENTION
A portable recreation and entertainment system for use with a motorized vehicle is provided which is adapted to be easily and quickly mounted to a rearward portion of the vehicle body, and be fully supported thereby. Ideally, the entertainment system is attached to the tow hitch (also known in the art as a tow bar), and is powered through an electrical connection directly with the vehicle (e.g., through a 6- or 7-way trailer cable harness) and/or an internal power source. The entire unit preferably locks into place with a hitch bolt, and is fully supported by tongue weight, i.e., via the connecting trailer support arm.
The portable recreation and entertainment systems described herein provide a self-contained, weather resistant, and fully operable entertainment unit which is accessed by a single large door, or two vertically stacked doors, each capable of opening a full 180 degrees. The present design provides battery stored power for television, video gaming, movie watching, and other similar entertainment. The invention also offers storage for up to 30 liters (approximately 8 gallons) of pressurized beer (e.g., a “half keg” or “pony keg”), mixed alcoholic or non-alcoholic drinks, both carbonated and non-carbonated. Also included in the present design are storage areas for such things as ice, silverware, a DVD player or video gaming unit, a portable barbeque unit (charcoal or gas), a portable table, and other amenities.
According to a one aspect of the present invention, a portable recreation system for use with a motorized vehicle is provided. The vehicle has a vehicle body with a forward end, and a rearward end having a trailer hitch extending therefrom. The recreation system includes a housing with a generally horizontal base portion and a top portion vertically distal therefrom. First, second, and third wall portions extend between the base and top portions, connecting the two portions, and thereby defining an opening that faces away from the vehicle. A support platform is attached, secured, or adhered to the housing, preferably by way of bolts. A support arm that is configured to sustain the weight and geometry of the housing connects the support platform to the rearward end of the vehicle body. The support arm preferably includes a hitch mating member that is configured to selectively mate with and thereby secureably lock the support arm to the trailer hitch.
At least one, but preferably two door members extend laterally across the opening, and pivotably connect to one of the first, second, or third wall portions to selectively rotate from a closed position to an open position. Ideally, a first door member extends laterally across a lower portion of the opening, and pivotably connects to the first wall portion to selectively rotate from a first closed position to a first open position. Similarly, a second door member extends laterally across an upper portion of the opening and operatively connects to the third wall portion to selectively rotate from a second closed position to a second open position. Each door member is preferably rotatably mounted to its respective wall portion by strap hinges, knuckle hinges, strap-n-t hinges, butt hinges, continuous hinges, lift-off hinges, and the like. Latch mechanisms are preferably attached to the first and second door members for selectively securing the first and second door members in their respective closed positions. Additionally or in the alternative, locking mechanisms can be secured to the first and second door members for individually locking each door member in its respective closed positions.
Ideally, at least one tail light fixture is secured to either the first or the second door member. More specifically, the portable recreation system preferably includes first and second tail lights attached, secured, or adhered to an outer surface of the first door member, wherein the first and second tail lights are oriented laterally distal from one another.
Preferably, the housing is configured to accommodate an electric power source. To this regard, one or more electric sockets are incorporated into the housing structure. The electric sockets are connected to the electric power source to distribute electrical power from the power source. The power source can be, by way of example, a gas powered electric generator, a car battery, a marine battery, or like element. Additionally, an electric cable configured to mate with a cable port in the vehicle body extends from the housing. The cable is preferably configured to transmit signals indicative of vehicle braking and turning operations from the vehicle to the various tail light fixtures. The cable is further configured to transfer electric power from the vehicle to the electric outlets mounted to the housing, and to recharge the electric power source.
Preferably, one or more shelves are secured to, and extend laterally between, the first and third walls. Similarly, one or more divider panels extend vertically between the base portion and one of the shelves to define a plurality of storage compartments.
The portable recreation system is adapted to safely and securely store a variety of amenities for easy transport. For example, a portable grilling assembly is preferably secured to an inner surface of the first door member. According to a first alternate embodiment, the grilling assembly is operable to pivot from a generally vertical stowed position to a generally horizontal use position. According to a second alternate embodiment, the portable grilling assembly extends substantially orthogonally from the first inner surface of the first door member in a cantilevered fashion when in the horizontal use position. In either instance, the portable grilling assembly preferably includes at least one vertical support member operatively attached thereto to pivot from a generally parallel stowed position to a generally vertical use position providing any necessary support.
An additional amenity that is preferably included in the portable recreation system is a table top operatively secured to the shelf portion, and adapted to transition from a generally horizontal stowed position, substantially inside the portable recreation system, to a generally horizontal use position, substantially outside the portable recreation system. According to a first alternate embodiment, the table top includes at least one vertical support member operatively attached thereto to pivot from a generally parallel stowed position to a generally orthogonal use position providing any necessary support. According to a second alternate embodiment, the table top extends rearwardly from the at least one shelf portion in a cantilevered fashion when in the horizontal use position. As an alternate variation, a portable table assembly can be secured to the top portion of the housing to selectively detach from a first stowed position to a second use position. One or more seats can also be secured to the first door member to pivot from a generally vertical stowed position to a generally horizontal use position, for use in connection with the table top or independently.
Additionally, a mounting frame is preferably secured to an inner surface of the second door member. The mounting frame is configured to mate with and thereby support a television set. A cooling device is preferably disposed within one of the plurality of storage compartments and configured to receive a large fluid container.
The above features and advantages, and other features and advantages of the present invention will be readily apparent from the following detailed description of the preferred embodiments and best modes for carrying out the present invention when taken in connection with the accompanying drawings.

Referring now to the Figures, wherein like reference numbers refer to the same or similar components throughout the several views, FIG. 1A is an isometric view of an exemplary motor vehicle, identified generally as 10, having attached thereto a portable recreation and entertainment system, hereinafter “recreation system 50”, in accordance with one embodiment of the present invention. Although the vehicle 10 is depicted throughout the several views, namely FIGS. 1A, 1C and 2A, as a standard pickup truck, the recreation system 50 can be incorporated into any vehicle platform, such as sedan- or coupe-type passenger cars, sport utility vehicles (SUV), recreation vehicles, and the like.
The pickup truck 10 has a truck body 12 having a forward end 14 with a cab portion 18, and a rearward end 16 with a bed portion 20 (also referred to in the art as a cargo bed or payload area) fixed, secured, or mounted adjacent to the cab portion 18. The bed portion 20 has a bed floor 22, a front end 24 opposing a rear end 26 (also referred to herein as the “rear vehicle structure”), and first and second sidewalls 28 and 30, respectively, each extending substantially orthogonally from the bed floor 22 to first and second horizontal panels 32 and 34, respectively.
The bed portion 20 also includes a tailgate assembly 36 (also referred to herein as a liftgate or tailgate door) which is preferably rotatably secured, e.g., via horizontal hinge pins (not shown) at the rear end 26 of the bed portion 20, adjacent to the bed floor 22, as seen in FIG. 1A. A latch mechanism having a locking device (not shown) is employed to selectively secure the tailgate assembly 36 in a substantially vertical closed position (shown in FIG. 1A), thereby forming an enclosure between the cab portion 18, first and second sidewalls 28, 30, and the tailgate assembly 36.
In one embodiment of the present invention, illustrated in FIGS. 1A-1D, the recreation system 50 includes a housing, identified generally as 52, having a generally rectangular and substantially horizontal base portion 54 oriented vertically distal from a generally rectangular and substantially horizontal top portion 56. The housing 52 further includes substantially vertical first and second lateral walls 58, 60, respectively, and end wall 62. The first and second lateral walls 58, 60 and end wall 62 extend substantially orthogonally between the bottom and top portions 54, 56 to create an enclosure 65 therebetween, and define an access port or opening 64, as best seen in FIGS. 1C and 1D. The recreation system 50 preferably has a height H, FIG. 1D, of 1.27 meters (m) or approximately 50 inches (in), a width W, FIG. 1D, of 1.4 m, or approximately 551⁄4 in, and a depth D, FIG. 1C, of 0.65M, or approximately 251⁄2 in. However, other values for the height H, width W, and depth D for the recreation system 50 may be usable within the scope of the present invention.
Ideally, each wall 58, 60, 62 is substantially-flat and generally rectangular, and fabricated from a material known to have a suitable strength for the intended use of the recreation system 50, such as, but not limited to, wood, aluminum, high strength plastics, and the like. The exterior of the recreation system 50 can be finished with an anti-corrosive, thermally insulating, weather proofing, and aesthetically appealing coating (e.g., dichromate paint, zinc plating, etc., not shown.) It is also considered to be within the scope of the claimed invention that each wall 58, 60, 62 take on additional shapes (e.g., a polygon, hexagon, etc.), include rounded or chamfered edges or corners, and have varying cross sections (e.g., crescent, semi-elliptical, etc.).
According to the embodiment of FIGS. 1A-1D, the housing 52 also includes a first large door member 66 vertically adjacent and substantially coplanar to a second large door member 68. The first door member 66 extends laterally across a lower portion 72 of the opening 64, whereas the second door member 68 extends laterally across an upper portion 74 of the opening 64. The first door member 66 is secured, mounted, or attached, preferably in a rotatable manner, e.g., via one or more vertical hinges 70, to the first lateral wall 58 to selectively rotate from a first closed position, FIG. 1A, to a first open position, FIGS. 1C and 1D. In a similar respect, the second door member 68 is secured, mounted, or attached, preferably in a rotatable manner, e.g., via one or more vertical hinges 70, to the second lateral wall 60 to selectively rotate from a second closed position, FIG. 1A, to a second open position, FIGS. 1C and 1D. By way of example, the vertical hinges 70 can be strap hinges, strap-n-t hinges, butt hinges, knuckle hinges, quick-pin hinges, continuous hinges, lift-off hinges, or any combination thereof.
When the first and second door members 66, 68 are in their respective closed positions, a weather proof, thermally insulated, resilient container is created and the recreation system 50 is in a transport state or position, as seen in FIG. 1A. In contrast, when the first and second door members 66, 68 are in their respective open positions, the opening 64 and, thus, the contents of the portable recreation system 50 are accessible, and the recreation system 50 is in a use state or position, as seen in FIG. 1C. To this regard, the first and second door members 66, 68 preferably include first and second latch mechanisms 104 and 106, respectively, configured to selectively secure the first and second door members 66, 68 in their respective closed positions, FIG. 1A. In addition or as an alternative to the first and second latch mechanisms 104, 106, the first and second door members 66, 68 can respectively include a first locking mechanism 108, FIG. 1C, and second locking mechanism 110, FIG. 1A, configured to selectively lock the first and second door members 66, 68 in their respective closed positions of FIG. 1A. Finally, it is also preferred that the first and second door members 66, 68 include first and second securing devices 130 and 132, respectively, configured to selectively hold the first and second the door member 66, 68 in their respective open positions, as best seen in FIG. 1D.
Turning to FIG. 1B, the portable recreation system 50 also includes a support platform 80 attached, secured, or adhered to the housing 52, preferably to the base portion 54 by way of bolts 82. A cantilevered, preferably tubular support arm 84, welded at a proximal end 85 to a peripheral edge of the support platform 80, extends longitudinally between the vehicle 10 and the support platform 80, and mates at distal end 87 with the rear vehicle structure 26. Preferably a substantially square hitch mating member 86 located at the distal end 87 of the support arm 84 inserts into a trailer hitch 88 extending from the rear vehicle structure 26. The support arm 84 is secured in a connected position with the trailer hitch 88, as shown in FIG. 1B, by a cotter pin 90 coupled with a locking pin 92 that is fed through aligned, cooperating apertures (not shown) in the support arm 84 and trailer hitch 88.
