Abstract: An articulated coupler permits vertical displacement of a towed vehicle relative to a towing vehicle while preventing lateral or horizontal displacement of the towed vehicle relative to the towing vehicle. Multiple linkage arms provide coupling for special configuration towed vehicles such as short wheel-mounted lifts that experience torsional forces due to the presence and absence of loads on the lift.

Abstract: A platform lift trailer includes a chassis to which a lift device is mounted. The chassis is configured to be coupled to a standard motor vehicle trailer hitch or the like using a coupler. Some embodiments of the coupler provide protection against larges torsional forces applied between a motor vehicle and coupled trailer when they are angularly displaced relative to one another. One or more ground-engaging wheel assemblies are mounted to the chassis to assist in supporting the weight of the lift and any cargo thereon. The platform lift trailer is highly adaptable so that a wide variety of lifts can be mounted to the platform lift trailer and thus to smaller motor vehicles. Adaptation of mobility lifts and the like to a larger array of motor vehicles is therefore possible. One or more embodiments of a trailer coupler use torque-limiting apparatus so that vertical angular displacements of a motor vehicle and a coupled trailer do not apply large forces directly between the motor vehicle and the trailer.

Abstract: Storable exterior lift cover systems, apparatus, devices, methods, etc. are configured to be used in connection with a lift device or the like (such as an exterior lift used to raise, transport, store and lower mobility devices like scooters, power chairs and the like) mounted to a motor vehicle using a trailer hitch or the like. To aid in protecting the lift and any cargo thereon, a covering apparatus has a foldable frame that can be unfolded to allow a pliable material cover to extend over the lift platform and any cargo. Retraction of the cover and folding of the frame compactly configures and stores the cover apparatus, for example in space between the lift platform and a motor vehicle to which the lift is secured. Embodiments of the storable exterior lift cover system permit easily deployment and storage of a cover that can be reliably transported externally in its deployed or stored configuration.

Abstract: A transfer device to assist a user in moving between vertically displaced locations has a storage enclosure mounted or mountable to the exterior of a motor vehicle. The storage enclosure protects components from external conditions, weather, etc., and typically is made of steel, plastic, etc. A user platform is supported on a drawer assembly that can be completely encased in the storage enclosure. Movement of the drawer assembly is controlled by a drawer extension mechanism that selectively extends and retracts the drawer assembly into and out of the storage enclosure between a stored position completely inside the storage enclosure and an operative position outside the storage enclosure. When the drawer assembly is in an operative position outside the storage enclosure, a platform elevating mechanism can raise and lower the user platform between a lower, compacted storage position and an elevated position using a scissors linkage that links the user platform to a drawer assembly support such as a tray.
