  • Patent number: 9623778
    Abstract: The apparatuses and methods disclosed herein may be pushed by hand or pulled by a motor vehicle. Thus, implementations of the transport device disclosed herein may have functions akin to a wheelbarrow or a dumping trailer, yet may provide easier and/or more efficient transportation and dumping functions over prior art wheelbarrows and dumping trailers. Implementation of the transport device disclosed herein also may be easier to push over an elevation or up a hill. Furthermore, in some implementations, the transport device disclosed herein includes four wheels and therefore can function like a cart. Still further, in some implementations, the transport device disclosed herein can have the functions of a wagon. In some implementations, the transport device includes a work bench.

  • Patent number: 9463730
    Abstract: A two-wheeled wheelbarrow, cart or transporter has an assisted lift dumping barrow providing continuously biased forward tilting of the barrow relative to the frame thereof through two gas springs while maintaining the legs and wheels on the ground. A first gas spring is connected to a right side handle of the frame of the wheelchair and to a right rear underside of the barrow. A second gas spring is connected to a left side handle of the frame of the wheelbarrow and to a left rear underside of the barrow. Each gas spring provides a continuous bias or pressure against the rear of the barrow for assisting in pivoting and lifting the rear of the barrow for dumping its contents. A latch keeps the barrow from raising until released. A separate rear barrow handle aids in overcoming bias of the gas springs for lowering the rear of the barrow.

  • Patent number: 7775531
    Abstract: The use of a pivotal coupling on a cart of the wheelbarrow type allows for a downwardly applied pressure to the user ends of the handles to tip the bucket to at least begin the dumping action of the cart. Following the initial downward pressure with the handles still elevationally displaced downward an upward lift applied to the user ends of the handles completes the dumping action of the cart. Use of multiple pivotal axises on the cart provide for an extremely efficient operation. Various enhancements are explained including locking of the orientation of the cart following the initial dump, wheel blocking to prevent rotation of the ground support wheel relative to the bucket during at least a portion of the final dumping action and stabilization enhancement to prevent lateral tipping of the cart during the final dumping action.

  • Patent number: 7234710
    Abstract: The present invention provides a manually powered drive assembly for a vehicle. A foot crank winds a helical torsion spring through a system of shafts and sprockets in a first direction. By releasing a brake applied to a wheel, or wheels, of the vehicle, the wound spring transfers a rotational movement from a spring shaft to a freewheel sprocket coaxially aligned with the axle supporting a wheel, so that the rotational movement upon the wheel assists a user in manually moving the vehicle. The drive assembly may be advantageously used with a wheelbarrow to assist in building up momentum for moving heavy loads.

    Abstract: An improved handtruck having an unloader mechanism for assisting in the removal of cargo from the handtruck. The unloader mechanism utilizes a cargo support pivotally mounted at the lower end of the handtruck. The cargo support is designed so that it can be maintained in a latched position when transporting cargo and can be unlatched to pivot away from the handtruck when unloading cargo. A pusher structure may be operatively connected to said cargo support to facilitate the removal of cargo from said cargo support. The pivot action of the cargo support causes a force to be exerted on the cargo by the pusher structure which urges such cargo down an inclined plane formed by the cargo support, thereby removing the cargo from the handtruck.

  • Patent number: 4921305
    Abstract: In a wheelbarrow having a bin (1) for the load, a ground wheel (2) at a front end of the bin and a handle (3) at a rear end, the handle (3) has a cam shaped extension (7) which forms a leg for the bin rear end and which is mounted on a pivot (4) carried on the bin. The handle (3) can be released from its normal position and then pivoted forward in the direction of the wheel (2). This action causes rotation of the cam and the bin rear end is lowered to near ground level to allow easy loading of the bin. When loaded the handle (3) can be returned to its position at the bin rear end and the cam simultaneously lifts the bin and load. The load may then be carried and emptied as with a conventional wheelbarrow.
