  • the present invention relates to a self-loading wheelbarrow designed to be operable by one operator.
  • a traditional wheelbarrow comprises a tray, two wheels and two handles extending rearwardly. It requires two operators to operate this kind of traditional wheelbarrow.
  • a first operator wheels an empty wheelbarrow to a loading area and holds the wheelbarrow by the handles in a steady position while a second operator fills the tray of the wheelbarrow with materials such as stones, sand, soil, or the like, by using a shovel. After the tray is fully loaded, the first operator wheels the loaded wheelbarrow to a dumping area to dump the load.
  • This kind of wheelbarrow loading operation requiring two operators, is labour consuming and ineffective.
  • a self-loading wheelbarrow configured to be operable by one operator characterized by a body having opposite sidewalls, a wheel system attached to said body for wheeling the wheelbarrow, a front loading sloping end extending forwardly of the wheel system, a rear receptacle end; a pair of laterally spaced handles attached to the body, and a fulcrum mechanism pivotally connected to said wheelbarrow and moveable between a retracted position where the fulcrum mechanism is clearing the ground to permit wheeling of the wheelbarrow, and an operative position where the fulcrum mechanism is in engagement with the ground below the wheel system and acts as a fulcrum while force is being applied to the handles to swing the front loading sloping shovel end of the body to shovel up a load from a pile of material.
  • a self-loading wheelbarrow wherein the fulcrum mechanism is further characterised by a fulcrum member pivotally connected to the body between the front loading sloping shovel end thereof, and the rear end, a free end of said fulcrum member being configured to engage to the ground at a level below the wheel system, a first link member pivotally connected to each side wall of the body adjacent the rear receptacle end thereof; a second link member pivotally connecting between the fulcrum member and the first link member, and a cross bar transversely extending behind the body and underneath the handles, each end of the cross bar being secured to the first link member at each opposite side of the body, whereby pushing the cross bar towards the front loading end drives the fulcrum mechanism from the retracted position to the operative position.
  • a self- loading wheelbarrow further characterised by a spring that is operatively connected to said first link member.
  • the springs provide the spring bias for the fulcrum mechanism.
  • the springs also assist the operator in forcing the sloping shovel end forwardly into the pile of material for loading the material into the body.
  • each of the first link members are further characterised by a first portion pivotally connected to the second link member, a second portion pivotally connected to the body, and a third portion secured to the cross bar.
  • a self- loading wheelbarrow wherein the fulcrum members are characterised by two legs, and a stop plate is provided on each fulcrum member at the free end thereof for limiting the penetration of the free end of each fulcrum member into the ground.

  • the body (12) has a front loading sloping shovel end (24) and a rear receptacle end (26).
  • the front loading sloping shovel end (24) extends forwardly of the wheel system and enables load materials such as stones, sand, soil, or the like, to be loaded directly without shovelling.
  • the rear receptacle end (26) is the end of the body (12) which prevents the loaded materials from sliding off the base (18).
  • the front loading end (24) has a sloping shovel blade portion (28) extending across substantially the width of the body (12).
  • the front loading sloping shovel end of the body (12) has tapered sidewalls (30) tapering towards the blade portion (28).
  • the two wheels (14) are rotatably mounted on opposite sidewalls (20) of the body (12) respectively.
  • Each of the two wheels (14) is rotatably mounted, such as, on an axle (32).
  • the axle is located rearwardly of the sloping shovel end of the body so as to permit material to be shovelled up from a pile directly into the body as described below. This feature also ensures that the weight of the load will be carried principally on the wheels, with only a little weight on the hands and arms of the operator.
  • the two laterally spaced handles (16) extend rearwardly and are fixedly attached to the body (12) respectively.
  • the handles (16) are fixedly attached to the opposite sidewalls (20) of the body (12) respectively.

  • a movable fulcrum leg member (36) is pivotally connected to each opposite sidewall (20) of the body (12) at the front loading end thereof by means of pivot pins (37).
  • the free end of each fulcrum leg member (36) is provided with a tapered end (38). This tapered end (38) is configured to anchor into sand or soil on the ground.
  • a stop plate (40) is provided at the free end of the fulcrum leg member (36) above the tapered end (38) in order to limit the penetration of the fulcrum leg member (36) into the ground.
  • first link members (42) is pivotally connected to each opposite sidewall (20) of the body at the rear receptacle end thereof.
  • the first link member (42) takes the form of a triangular plate (44).
  • Each triangular plate (44) has a first corner (46), a second corner (48), and a third corner (50).
  • the first corner (46) of each triangular plate (44) is pivotally connected to the body (12) by means of a pivot pin (52).
  • a cross bar (54) transversely extends behind the body (12) with both ends each being secured to the second corner (48) of the respective triangular plates (44).

  • the other end of the second link member (56) is pivotally connected towards the free end of a respective fulcrum leg member (36) by means of a pivot pin (60).
  • the fulcrum leg members (36), the first and second link members (42), (56), and the cross bar (54) together form a fulcrum mechanism.
  • a spring (62) extends from the first link member (42) to the handle (16) on each side of the body (12).
  • the springs (62) are employed to bias the fulcrum mechanism to a retracted position where the fulcrum members (36) are out of contact from the ground, (Figs 2 and 4).
  • the body 12 and the fulcrum mechanism (36), (42), (54), (56) are preferably made of metal, such as steel, or any other suitable materials.
  • FIGS. 2, 3 and 4 show the operation of the self-loading wheelbarrow (10) of the present invention.
  • an operator In order to shovel up a load from the loading area, an operator first wheels the wheelbarrow (10) towards a pile of material in the loading area. The operator then tilts the wheelbarrow (10) forwardly (Fig 2) by lifting up the two handles (16) so that the handles (16) are at an approximately 11 o'clock position and the wheels (14) are lifted off the ground, as shown in Fig 2. In this position, the blade portion (28) of the front loading sloping shovel end (24) of the body (12) is angled downwardly, and the sloping shovel end (24) can begin to sink into the pile of material to be loaded. The operator then swings the handles further upward to approximately an 11 o'clock position (Fig 3).
  • the load slides backwards from the front loading end (24) to the rear receptacle end (26) of the body (12) by means of gravity. This sliding of the load from the front loading end (24) to the rear receptacle end (26) of the body (12) can be facilitated by shaking the body (12).
  • the wheelbarrow may be fully loaded after one shovelling operation.
  • the fulcrum mechanism is spring-biased to the retracted position by means of springs, it is appreciated that the fulcrum mechanism can be retained in the retracted position by other devices such as friction clips or counterweights.
  • the wheelbarrow of the present invention can be used as a conventional wheelbarrow or a wheeled shovelling device. Wheeling of the loaded wheelbarrow requires much less effort than the conventional wheelbarrow, because the weight of the load is . carried over the wheels. The weight is not carried on the arms of the operator, to any significant extent.
