Abstract
A trailer has a load carrying bed to which a carriage frame and a coupling are slideably attached to opposite sides. Actuators are provided to move the bed with respect to both the carriage frame and the coupling. At least one wheel is attached to the carriage frame to support the utility trailer on the ground. When the coupling is connected to a hitch on a motor vehicle, operating the actuators lowers the bed against the ground to facilitate loading and unloading and raises the bed to enable the trailer to travel.
Claims21
A utility trailer for towing on a road by a motor vehicle, that utility trailer comprising:
- a platform which supports a load carried by the utility trailer while traveling on the road;
- a coupling moveably connected to the platform for mating with a hitch on the motor vehicle;
- a carriage frame moveably connected to the platform;
- an actuator assembly operably engaging the platform to produce raise and lower the platform with respect to the road;
- and
- a wheel attached to the carriage frame to support the utility trailer on the road.
A utility trailer for towing on a road by a motor vehicle, that utility trailer comprising:
- a bed on which a load on placed while the utility trailer travels on the road;
- a carriage frame moveably connected to the bed;
- a first actuator connected to the bed and the carriage frame to produce vertical motion there between;
- at least one wheel attached to the carriage frame to support the utility trailer on a road;
- a coupling moveably connected to the bed for mating with a hitch on the motor vehicle;
- and
- a second actuator connected to the bed and the coupling to produce vertical motion there between.
A utility trailer for towing on a road by a motor vehicle, that utility trailer comprising:
- a bed on which a load on placed while the utility trailer travels on the road, the bed having a platform with first and second sides, a first frame attached to the platform adjacent the first side, and a second frame attached to the platform adjacent the second side;
- a carriage frame slideably connected to the first frame;
- a first linear actuator connected to the bed and the carriage frame to produce vertical motion there between;
- only one wheel supporting the utility trailer on a road and being attached to the carriage frame;
- a coupling slideably connected to the second frame for mating with a hitch on the motor vehicle;
- and
- a second linear actuator connected to the bed and the coupling to produce vertical motion there between.
