Definitions

  • a hand-propelled vehicle with tipping body or load platform A hand-propelled vehicle with tipping body or load platform
  • the present invention relates to a hand-propelled vehicle, such as a trolley or a wheelbarrow, specifically a wheelbarrow, and more specifically a tipping wheelbarrow.
  • a hand-propelled vehicle such as a trolley or a wheelbarrow, specifically a wheelbarrow, and more specifically a tipping wheelbarrow.
  • PRIOR ART A common problem with the use of wheelbarrows is the need to tip them to unload the transported material. The tipping is performed by pivoting the wheelbarrow around the wheel axis levering on the lifting handles. This requires a considerable effort, which may cause injury to the operator and however limits the admissible load.
  • Italian patent application Ml 2003 A 002277 suggests a wheelbarrow provided with a tipping mechanism: the handles slide in an element hinged to a rear stand, in turn hinged onto the tipper body and propped on the ground.
  • the handles are rigidly fixed to a wheel axis support, underneath it, the support also being hinged above to the tipper body.
  • the wheel support is induced to pivot forwards and the hinging point with the tipper body descends. Concurrently, the rear stand is lifted and this causes the tipper body to be tipped forwards.
  • This system is not entirely satisfactory as concerns reducing the operator's effort and furthermore, the system which allows the handles to slide is more complex to manufacture with respect to a simple hinge and is subject to jamming or frictions due to foreign bodies, rust or other. It would therefore be desirable to provide a wheelbarrow with a tipping mechanism displaying a simpler construction and being most effective in reducing the operator's effort.
  • a hand-propelled vehicle such as a trolley or a wheelbarrow, having a load platform or tipper body, at least one steering element adapted to be gripped by a rear end, a support hinged to said platform or tipper body, at least one wheel rotationally fixed to said support, a stand hinged to said platform or tipper body and adapted to rest on the ground on a resting end, characterised in that said steering element is hinged to a front end of said support and, in an intermediate position between the ends, to said stand between the hinging point to the load platform or tipper body and said resting end.
  • the steering element preferably comprises a handle, and preferably two handles adapted to be gripped with the hands.
  • the foregoing hinges all have a hinging axis parallel to the rotation axis of said wheel.
  • the hinging point of the support with the tipper body or platform preferably in the lower part of the latter, is placed in front of the hinging point of the stand with the platform or tipper body.
  • the hinging axis of the steering element with the support coincides with the rotation axis of the wheel.
  • figure 1 diagrammatically shows a bottom view of a wheelbarrow according to the present invention
  • figure 2 diagrammatically shows a side view of the wheelbarrow in figure 1
  • figure 3 diagrammatically shows a side view of the wheelbarrow in the previous figures in a tipped position of the tipper body
  • figure 4 diagrammatically shows a bottom view of a wheelbarrow according to another embodiment of the present invention
  • figure 5 diagrammatically shows a side view of the wheelbarrow in figure 4
  • figure 6 diagrammatically shows a perspective view of the wheelbarrow in figures
  • figure 7 diagrammatically shows a perspective view of an element adapted to hinge together the various components of a wheelbarrow according to the present invention.
  • the figures show a wheelbarrow according to the present invention.
  • the wheelbarrow comprises a tipper body 1.
  • a support 2 supports the axle 3 of the wheel 4 in a known manner, e.g. by means of bolts passing through an antifriction bushing.
  • the support is hinged above to the lower part of the tipper body with means 5 which may be of the known type; e.g. the support may comprise two arms 6 and 6', the ends of which terminate in a tube fixed to the tipper body, as in the case shown.
  • the stand 7 is also hinged to the tipper body, in an appropriate position, behind the support 2 by means of the hinging means 8, also of the known type.
  • the end 9 opposite to the hinging point is adapted to rest on the ground.
  • the steering element comprises the handles 10 and 10'. They are hinged in front onto the support 2. According a preferred embodiment, the handles are hinged onto the support at the wheel axis, even though it is possible to make hand-propelled vehicles in which the support extends beyond said axis, and the hinging point of the handles or in any case the steering element is different, e.g. underneath and behind the wheel axis.
  • the axle 3 may be either integral with the wheel, or with the steering element, or with the support, or may also pivot with respect to them all. A person skilled in the art may make the connections in different manners allowing the free rotation of the steering element, of the support and of the wheel.
  • the ends 11 and 11' of the handles, opposite to the wheel are intended to be gripped by the person manoeuvring the vehicle.
  • the handles are hinged to the stand 7 in an appropriate point 12 and 12', intermediate between the end 9 and the hinging point of the tipper body or platform, e.g. by means- of bolts with bushings or in any known manner. They may be connected directly, as shown, or a crossbar may join the two handles and be hinged to the stand, if the width of the stand and of the handles differs more than shown. Every appropriate solution differing from that described may be used to make the pivoting connection. As shown in figure 2, the tipper body 1, the support 2, the steering element and the stand form an articulated quadrilateral. In order to tip the tipper body and unload the contents in front of the wheel, one must lift the steering devices, specifically the handles by the grip, holding the resting point of stand 7 on the ground, which may be performed by an operator by putting his or her foot onto end
  • FIG. 9 which may be, according to a preferred embodiment of the invention, a horizontal crossbar arranged essentially parallel to the rotation axis of the wheel, i.e. transversally to the direction of travel of the vehicle.
  • the wheel 4 is made to retract towards the stand 7.
  • Figure 3 shows the wheelbarrow in a tipping position of the tipper body after the above-described operation: the operation of the mechanism is apparent by the comparison with figure 2.
  • the stand 7 will turn about the resting point on the ground lifting the hinging point thereof with the tipper body with respect to the hinging point of the latter with the support 2. This causes the forward rotation of the tipper body, about the hinging point with the support.
  • the operation occurs with a reduced effort by the operator.
  • the support 2 given the hinging on the ends, allows the movement. In the configuration shown, the above-described operation will also cause a certain retraction and lowering of the hinging point of the support with the tipper body. By lowering the levers, the opposite operation is easily performed, returning the wheelbarrow to the configuration shown in figures 1 and 2.
  • the tipper body may, according to a possible embodiment of the invention, tip to touch the wheel 4 or possibly a mudguard. Different stopping means may be provided, if required.
  • a person skilled in the art will know how to identify the relative distances of the hinging points, the length, the size and the arrangement of the various parts, so as to minimise the effort and to give adequate strength and stability to the vehicle, as the presence of reinforcements, e.g. for the tipper body, to withstand the torque applied when tipping with a full load.
  • the handles form an elbow shown by numerals 13 and 13' between the hinging points with the support and the stand. This provides the right inclination to the handles and allows the hinging at the wheel axis.
  • the steering element is adapted to provide a prop for the tipper body or platform when it is in the transportation position, i.e. not tipped. In this manner, it is a stopper for the linkage is made.
  • Figure 2 clearly shows how the handles are shaped so as to allow a comfortable grip and appropriate narrow in proximity of other components to make the connections with the latter.
  • points 16 and 16' they provide a resting point on the bottom of the tipper body, supporting it in the position shown, adapted for both parking and transportation, i.e. for being hand- propelled with or without load. Reinforcements may be contemplated in the resting point, and appropriate seats may be obtained in the tipper body or on the handles, if deemed appropriate. Other stopper systems may however be made, if deemed appropriate.
  • the handles may also be removable in order to transport or store the vehicle.
  • the parts 14 and 14' may be detached from the rest.
  • tubular handles it is possible to make a coupling shown by numeral 15, in which one part ends with a narrowing adapted to be inserted in the end of the complementary part and the two parts may be locked with pins, bolts or other means. If, as in the case shown, the coupling is made before the resting point of the tipper body or the platform, the removal thereof allows a further lowering of the tipper body and a better folding of the components, decreasing the dimensions of the vehicle.
  • Figures 4 and 6 show a wheelbarrow according to a different embodiment of the invention.
  • the stand 27 to be adapted to provide a prop for the tipper body 21 , when this is in lowered position instead of the steering elements, which are the handles 30 and 30'.
  • the stand presents an elbow 40 between the hinging point 28 with the tipper body and that 32 with the handles, so that the portion 41 between the elbow and the hinging point 8 forms such a prop, as shown in figure 5.
  • the position of the hinging points, and specifically of the support 22 with the tipper body are such to allow a sufficient tipping of the tipper body before it comes into contact with the wheel.
  • the support must be sufficiently long.
  • the tipper body may reach at least one position in which its upper edge 42 is vertical.
  • the shape of the stand 27 will be such as to facilitate the tipping in the manner previous described above. For example, it may be lifted off the ground when the wheelbarrow rests in position with the tipper body not tipped and may abut by effect of the tipping. As mentioned, the tipping must be possible with a non-excessive effort by the operator.
  • a wheelbarrow according to the proportions shown in figures from 4 to 6 was made with a hinging height 25 of the support 22 with the tipper body over that of the hinging points 28 of the stand 7 with the tipper body (with the wheelbarrow in non-tipping position and resting on the ground) between 12 and 13 cm and the projection of such hinges at a distance from the ground of between 16 and 17 cm.
  • the length of the portion of the rear handles from the hinging point 32 is approximately 76 cm.
  • the other dimensions may be obtained by a person skilled in the art and the dimensions may be varied according to needs without departing from the spirit of the invention.
  • the hinges may be made, as mentioned, in any known manner.
  • the hinge of the stand 27 with the tipper body of the wheelbarrow in figure 4 is made using the element 50 in figure 7.
  • a tube is welded transversaily to the tipper body and a bolt is screwed through the hole 51 in the element 50 into the tube at its end, coaxially with the tube, in appropriate manner.
  • the portion 52 of the element 50 is inserted in the end of a tube forming the stand 27 and is secured to it by means of a pin or bolt inserted in a through hole (not shown in the figure) in said portion and in the walls of the tube; thread lock systems may be used.
  • the element may be made of appropriate material, e.g. metal or plastic material.
  • a similar hinging system may be provided also-for the support 22 or at the wheel. In any case, other hinging systems may be adopted without any restriction.
  • the manufacture of a wheelbarrow has been shown in detail but as mentioned a tipping platform trolley may be made by changing the necessary parts without departing from the spirit of the invention. Variations and changes to the illustrated embodiment and to the construction materials of the vehicle are possible and may be chosen by a person skilled in the art in an appropriate manner.
