The present application relates to personal off-road vehicles. More particularly, the application discloses a small off-road vehicle, commonly referred to as a utility terrain vehicle, with improvements geared towards applications for military, law enforcement, and emergency personnel.
Over the last several years, the popularity of utility terrain vehicles (also referred to as “UTVs”) has greatly increased. UTVs are practical and versatile, as the vehicle may be used for work or leisure related tasks. The compact nature, mobility, and traction of UTVs means the vehicles are capable of traversing all sorts of surfaces, from the relatively smooth surfaces of paved roadways to rough, uneven terrains, including rocky areas, woodland trails, wetlands, and sand dunes. UTVs are also typically designed to pull or push various objects such as a trailer or a snow-plow.
A typical UTV is a personal vehicle and may contain side by side seats. Such a vehicle comprises four or more wheels mounted to a frame, the front wheels being steerable. A fuel tank and a seat are disposed on an upper portion of the frame. The engine, which represents one of the heaviest components of the vehicle, is typically mounted in a central portion of the vehicle. The engine location is specifically chosen to ensure a proper weight distribution. If the engine is water cooled, a radiator will be provided in front of the engine. The fuel tank is adjacent the engine.
While such a configuration provides vehicles with performance levels that are more than adequate, there are nonetheless many disadvantages associated with it. For example, if the vehicle is to be used for special utility purposes, or by emergency personnel or military personnel, additional vehicle storage, stability, and utility are required from what is typically found in a standard model known in the art. Particularly, absent in the prior art is a system with a large liquid holding tank.
A first embodiment includes a utility terrain vehicle having four or more wheels, a frame held above the ground by the wheels, and a liquid storage tank. The liquid storage tank is attached to the frame to create a low center of gravity for the utility terrain vehicle.
A second embodiment includes a utility terrain vehicle having two front tires and two rear tires, a vehicle frame held above the ground by the front tires and the rear tires, one or more seats, and a liquid storage tank. The seats have a seat frame, a lower seating surface, and an upper seating surface. The liquid storage tank is located above the vehicle frame and below the seat frame.
A third embodiment includes a utility terrain vehicle having two front tires and two rear tires, a vehicle frame held above the ground by the front tires and the rear tires, a subframe attached to the vehicle frame to provide additional support to the vehicle, a first seat and a second seat, a flatbed, a pump carried on the flatbed, a liquid storage tank, and an inlet to the liquid storage tank. The first and second seats have a combined seat frame, a lower seating surface, and an upper seating surface. The liquid storage tank is located above the vehicle frame and below the lower seating surface.
Other elements of UTV 10 include various support structures, such as flatbed 20 and cage 18. Cage 18 is connected to main body portion 16 and assists in preventing injury to passengers from passing branches or similar obstacles, as well as acting as a support in the event of a vehicle rollover. Cab 24 is defined by main body portion 16 and cage 18. Flatbed 20 extends rearward of cab 24. Flatbed 20 supports pump 22, flatbed tank 38, and liquid tank inlet 36. Pump 22 and liquid tank inlet 36 are connected to tank 30 with hoses. Liquid tank inlet 36 has the capacity to retain some liquid and is thus capable of acting as a surge when filing liquid tank 30. Liquid tank inlet 36 creates a pressure differential between liquid tank 30 and liquid tank inlet 36 so that the liquid in liquid tank inlet 36 moves through the hose into liquid tank 30. UTV 10 also includes gas tank 21 located rearward of liquid tank 30 on the passenger's side, to supply gas to the engine. UTV 10 further includes seat frame 26, upper seat 28, and lower seat 29. Seat frame 26 is disposed on specialized tank 30, and upper seat 28 and lower seat 29 are attached to seat frame 26. Upper seat 28 provides support for the backs of the driver and passengers and lower seat 29 provides support for the sitting of the driver and passengers.
In the embodiment shown, UTV 10 includes three seats: a driver's seat, a first passenger's seat next to the driver's seat, and a second passenger's seat rearward of the driver's seat. A portion of flatbed 20 extends behind the first passenger's seat and next to the second passenger's seat. In other embodiments, UTV 10 may include more seats or fewer seats. Front footrest 32 is forward of liquid tank 30 and provides a place for the driver and first passenger to rest their feet. Rear footrest 34 is located rearward of liquid tank 30 behind the driver's seat and provides a place for the second passenger to rest their feet.
In the embodiment shown, tank 30 has the following dimensions: height H of tank 30 is 15 inches; width Wp of tank 30 on the first passenger's side is 32 inches; width Wb of tank 30 on the driver's side bottom is 15 inches; width Wt of tank 30 on the driver's side top is 21 inches; forward length Lf of tank 30 is 59 inches; and rear length Lr of tank 30 behind the passenger's seat is 37 inches. The dimensions of tank 30 can be adjusted based on the size and arrangement of UTV 10. For instance, in the case that UTV 10 does not have a second passenger's seat, tank 30 is capable of being shaped to fill the space that is left open for footrest 34 in the embodiment shown.
Tank 30 extends under the driver's seat and passenger's seat, and rearward of the passenger's seat under a portion of flatbed 20. The space behind the driver's seat is left open for rear footrest 34. This allows the second passenger to have leg room when they are riding on UTV 10. The second passenger's leg room is further expanded with slanted aft end 56. Slanted aft end 56 allows tank 30 to extend fully rearward under the driver's seat, while at the same time providing more open space for rear footrest 34. Top side 50 of tank 30 needs to extend fully rearward under the driver's seat to support seat frame 26.
Tank 30 is shaped to be placed under seat frame 26 on UTV 10. Tank 30 is capable of supporting the weight of seat frame 26, upper seat 28, lower seat 29, a portion of flatbed 20, and the sitting weight of an operator and passenger. In the embodiment shown, tank 30 is made out of aluminum, although any material capable of supporting the weight and holding liquid can be used. The materials best suited for supporting the additional weight are rigid materials with a high tensile strength, and the materials best suited for holding liquid are rigid and non-corrosive materials. Tank 30 has the capacity to hold over 100 gallons of liquid.
Tank 30 as designed and as located on UTV 10 provides many benefits, especially when UTV 10 is being used for military, emergency, medical, and fire protection purposes. In the prior art, liquid storage tanks are carried on flatbeds of a UTV. Carrying a liquid storage tank on a flatbed greatly raises the center of gravity of the UTV, which decreased the handling of the vehicles and increased the possibility of a roll-over. Placing tank 30 under seat frame 26 gives UTV 10 a low center of gravity, which improves the handling of UTV 10. When tank 30 is empty, the center of gravity of UTV 10 is similar to the center of gravity of UTV 10 without tank 30. When tank 30 is full, the center of gravity is still lower than the height of the tank and thus low on the vehicle, which reduces the risk of a roll-over. Placing tank 30 under seat frame 26 also distributes the weight of the liquid more evenly across front tires 12 and rear tires 14, which again results in improved handling.
Placing tank 30 under seat frame 26 allows for additional equipment to be carried on flatbed 20 of UTV 10. Opening up this space increases the effectiveness of UTV 10 as a vehicle that can be used in fire fighting. Tank 30 allows for a larger amount of water to be carried on UTV 10 and leaves flatbed 20 open to carry a pump, hose, and other firefighting tools. Opening up flatbed 20 also increases the effectiveness of using UTV 10 for emergency purposes. Flatbed 20 is capable of holding a stretcher and other medical equipment. The configuration of UTV 10 also allows a paramedic to tend to a patient while UTV 10 is moving. Tank 30 is also capable of holding additional fuel for UTV 10, which greatly increases the travel distance of UTV 10. UTV 10 can also hold fire suppressant materials, chemical mixtures for pest control, and any other liquid.
