摘要： Embodiments of the invention are designed to be improvements over existing wheelbarrows. Certain embodiments comprise a frame, one or more weight-bearing wheels, and a pan. In certain embodiments, a wheelbarrow comprises a bight or a bumper having wheels. The wheels on the bight or bumper are located to the sides of a weight-bearing wheel. In certain embodiments, wheels located on each side of a bight or bumper portion allow a user to maneuver a wheelbarrow up or down a curb, or navigate stairs without causing damage to surfaces. Certain embodiments of the invention allow more efficient unloading of the contents of a wheelbarrow bed. Certain embodiments are designed to retrofit on existing wheelbarrows.

摘要： A three wheel cart that is adjustable in both length and width for cargo such as ice chests. The cart provides a pair of rear wheels, a horizontal load platform, and a front drawbar with a third wheel for easy pulling or pushing. The drawbar and third wheel retract under the cart. All adjustments are made without wrenches utilizing a large soft hand nut. The width adjustment is interconnected by a mechanism so that cargo width retainers slide in and out simultaneously along with the cart main wheels. When the drawbar is raised into its towing position the cart's front support leg is levered off the ground by the third wheel. This capability minimizes the lifting effort required when towing the cart. As the drawbar is lowered the support leg becomes an automatic parking brake. The operator cannot abandon the cart without the brake being applied.

摘要： A wheelbarrow includes three wheels so that it may be pushed without being lifted, thereby minimizing the potential for operator injuries due to lifting the wheelbarrow. A braking mechanism including a lever having one end for engaging a user's hand or foot, and another end for engaging a sprocket secured to one of the wheels, may be used to resist movement of the wheelbarrow when such movement is not desired.

摘要： A vehicle for transporting loads over rough terrain having a seat mounted on a bracket which is mounted on a frame which rides on a single wheel carried within a fork. A handlebar with vertical handgrips provides control in a variety of positions in use, and a pair of normally retracted wheels which can be extended to stabilize the vehicle. The vehicle is adjustable in length, wheel size, handlebar size and presentation, load size, angle, and center-of-gravity relative to the wheel, and the number of wheels in contact with the ground.

摘要： A motorized wheelbarrow comprising a frame having a pair of handles with each handle having a proximal and a distal end and a pair of downwardly depending support elements. A first wheel is secured to the distal ends of the pair of handles by a frame element and a rear set of wheels is secured to the proximal ends of the pair of handles by a frame element. A mounting element is secured to the frame for supporting a drive engine. A drive mechanism including a chain and a sprocket is operably linked to a toothed wheel and to the drive engine. The toothed wheel includes an internal brake drum and internal brake shoes. A centrifugal clutch for engagement with the drive mechanism is operably engaged to a throttle mechanism and to the drive engine, and a load bucket is mounted to the frame.
