20080315538 | Leveling system and device for a recreational vehicle - A system for leveling recreational vehicles and the like consists of two motors operating simultaneously but independently to lift a trailer or other vehicle having vehicle-axles. The system comprises one portable and motorized lifting unit that can be deployed selectively on either side of the vehicle, or both, as required. The motorized lifting unit comprises a pair of motorized jacking units connected by a common and centrally positioned tube-type rail member. A pair of motorized jacking units electrically couple to a controller. The vehicle battery or another external power supply powers both electric motors. | 12-25-2008 |
20090091095 | PNEUMATICALLY ELEVATABLE HAND TRUCK - A pneumatic cylinder assembly and a method for lifting a hand truck frame generally vertically away from a ground surface exploits a cylinder housing including a longitudinal axis and first and second ends. The cylinder housing defines a cylinder cavity at the first end and a port generally at the second end in operative communication with the cylinder cavity and has at least one frame attachment point for attachment of the housing to the hand truck frame. A piston in the cylinder cavity is moveable in a first direction. A fluid space is defined between the actuation surface within the cylinder housing. An inlet valve is configured to admit a working fluid into the fluid space through the port at a pressure greater than an ambient pressure, thereby urging the piston in the first direction thereby to cause the movement of the piston in the first direction lifting the truck. | 04-09-2009 |
20090091096 | System and Methods for Adjustment of Vehicle Bodies - A vehicle body and vehicle frame assembly is disclosed that includes a complete rolling chassis with wheels, motor, drive train, transmission and all other components found in contemporary automotive vehicles with the addition of a scissor lift situated in the center of the vehicle frame that is connected to the chassis frame at the lower end and to the body of the vehicle at the upper end through a frame and turntable device. Controls are used to lower, elevate and rotate the body of the vehicle relative to the chassis, so that observers may readily view the chassis components. | 04-09-2009 |
20100066041 | Adjustable height trailer - The adjustable height trailer is a fifth wheel-type trailer with a single rear axle supporting the rear of the trailer and a fifth wheel hitch supporting the front. The rear axle and hitch have adjustable height suspensions, allowing the trailer to be lowered or raised uniformly while remaining hitched to the towing vehicle. One embodiment is configured as a livestock trailer with a series of stall positions therein. The loading and exit doors are generally diagonally opposite one another. A series of adjustably positionable partitions is installed on overhead tracks, with a partition placed between each animal as they are boarded and positioned in the trailer. Animals depart the trailer through the opposite door, with the partitions being repositioned correspondingly. The trailer suspension allows the trailer to be lowered to the underlying surface to facilitate loading and unloading animals therefrom, or other commodities, depending upon the trailer configuration. | 03-18-2010 |
20100096819 | Vehicle Leveling And Attitude Positioning System - A vehicle leveling assembly includes a plurality of jack assemblies corresponding to four quadrants of a vehicle, and a plurality of sensors for determining jack position and rate of movement. A method of detecting contacting between the shafts of the Jack assemblies and the ground includes measuring pulse width of current emitted by the hall effect sensor to monitor the speed of the shafts and recognizing contact with the ground when the shaft slows down. A method of detecting contacting between the shafts of the jack assemblies and the ground includes measuring the electric motor current signal and correlating a pulse from the current signal to the electric motor revolutions per minute and travel of the shafts. A method of calibrating the leveling assembly includes measuring a change in inclination as the jack assemblies are extended a known distance to determine the distance between the jack assemblies. A method of leveling includes extending the shafts an additional compacting distance to ensure accurate calculations of shaft extension, prior to attempting to level the vehicle. | 04-22-2010 |
20110169231 | System for Leveling Recreational Vehicles and the Like - A system and method for leveling a vehicle when stationary. The system includes three zones with a first zone at the front end, and the second and third zones on opposite sides of the vehicle. All zones include leveling jacks, each having a blind side and a rod side. At least one leveling jack is located in the first zone, and at least two leveling jacks are located in each of the second and third zones, straddling the wheel on that side, and the blind sides of the jacks in each zone are connected together. The rod sides of all of the jacks are connected to a common fluid line, which typically is low fluid or pressure free. In operation, once the vehicle is stationary, all of the jacks are extended from a retracted position to an extended position meeting the surface upon which the vehicle is located. Fluid is then applied to the blind side of one of the second and third zone leveling jacks to raise the lower of the two sides, and, if the front end is higher than the rear, fluid to the blinds of the leveling jack in the first zone is reduced, while if the front end is lower than the rear, fluid to the blind side of the leveling jack in the first zone is increased, with the vehicle then being level. | 07-14-2011 |
20130127125 | Multi Use Recreational Utility Vehicle - A micro weight enclosure when fully loaded with gear and equipment is capable of being towed by vehicles with gross tow weight ratings of less than 1000 lbs. This enclosure does not utilize a traditional chassis, rather uses common manufacturing of panel assemblies mechanically attached together forming the basic structural elements required for strength at minimal weight and reduced wind drag. | 05-23-2013 |
20150137463 | SYSTEM AND METHOD OF USING AIR SUSPENSION TO IMPROVE VEHICLE UNLOADING - An aft suspension system for a pickup truck comprises four corner assemblies, where one corner assembly is located at a suspension position corresponding to each of the wheel corners for the vehicle. An air supply unit includes a reservoir, a compressor, and an ECU is fluidly connected to the corner assemblies. The air supply unit is capable of independently adjusting the corner assemblies from one another. The air suspension system is operable to place the corner assemblies in a unloading position or a trailer, which corresponds to two of the corner assemblies in raised positions and the other of the two corner assemblies located in lowered positions to create a maximum height differential between the front and rear corner assemblies. | 05-21-2015 |
20160031283 | RECREATIONAL UTILITY VEHICLE - A recreational utility vehicle having an enclosure with a bottom wall and first and second side wall assemblies is provided. The first and second side wall assemblies and the bottom wall define an interior region. The vehicle further includes a first suspension assembly coupled directly to the first side wall assembly, having a first swing arm assembly with a first operational position in which a first portion of the bottom wall of the enclosure is at a predetermined distance from a ground level elevation. The first swing arm assembly has a second operational position in which the first portion of the bottom wall of the enclosure is at the ground level elevation. The vehicle further includes a second suspension assembly operably coupled directly to the second side wall assembly. | 02-04-2016 |
