Definitions
- the invention relates to a wheelbarrow with a frame with at least one wheel and with a load receiving device for receiving loads.
- Known wheelbarrows have a frame on which a wheel and a receptacle for loads are arranged.
- the load-carrying device is usually a trough-shaped container or another hollow vessel.
- the frame is equipped with two supports, with which the wheelbarrow is supported in the rest position together with the wheel on a surface.
- the frame on two handlebars to lift the supports of the wheelbarrow with two hands from the ground and can go from the rest position to the driving position. In the driving position, only the wheel touches the ground.
- the shape of the load suspension affects the position of the center of gravity when the wheelbarrow is loaded. This is preferably located near the wheel, so that only a small torque must be applied to lift the supports.
- the frame usually consists of a tube which is brought into a form necessary for the frame.
- the tube is made of metal. It is bent to have the shape with the handle bars, the struts and the wheel suspension.
- a disadvantage proves that the metal tube is not adapted to the various requirements in terms of stability in the different areas of the frame.
- the frame has a high weight and is expensive to manufacture.
- the wheelbarrow according to the invention with the features of claim 1 is characterized in that the frame of at least one elongated
- Hollow body is formed, which has different cross sections in different sections.
- the outer shape of the cross section in at least one rectilinear section is oval and not circular. It is the cross section of the hollow body perpendicular to the longitudinal direction of the hollow body.
- the hollow body has the shape of a tube with some curvatures. Through this tube, a longitudinal direction is specified in the various sections.
- the outer shape of the cross section refers to the outwardly facing side of the wall of the hollow body.
- the oval shape which deviates from a circular shape, provides greater stability, in particular if the extent in the vertical direction is greater than in the horizontal direction.
- the cross section of the hollow body is adapted in different sections to the different requirements in terms of stability and weight loading. Sections in which particularly high forces act have a greater wall thickness than sections in which lower forces occur.
- the hollow body of the frame is optimally adapted to the specific requirements. Since the wall thickness is greater only in those sections where large forces occur, material can be saved in those sections where lower forces occur. This leads to the fact that the frame can have a lower weight with higher stability than with known wheelbarrows. In addition, a sufficient rigidity of the frame is given even with torsion.
- the hollow body of the frame may for example consist of plastic and be manufactured by means of a Fluidinjetechnischstechnik.
- the hollow body may consist of a metal tube which is brought into the desired shape by means of hydroforming, also called hydroforming. Both materials and methods are suitable for the production of large numbers of racks. They allow the production of hollow bodies with curvatures required for a frame, with different cross-sections in different sections and with an oval outer contour.
- the oval outer shape of the hollow body in at least one portion in the vertical direction to a greater extent than in the horizontal direction. This shape ensures that the frame is particularly stable with respect to weight forces of loads arranged in the load-bearing device. These weight forces act in the vertical direction.
- the wall thicknesses of the hollow body in different rectilinear portions of the frame are different.
- the wall thickness is preferably higher than in sections with less force. This ensures a higher stability of the wheelbarrow.
- Hollow body in at least one section of a curvature.
- the wall thickness of the hollow body is smaller in the area directed inwards with respect to the curvature than in the area directed outwards. This ensures that act on the outwardly facing area larger forces and thus a higher stability is needed than in the inward-facing area.
- Such a curvature is provided for example in the section of the supports.
- the outwardly facing area in the rest position faces the ground. He is therefore exposed to a higher mechanical load due to friction, especially when settling the wheelbarrow and a movement of the
- Hollow body of the frame in the section of the supports on a curvature has a plurality of ribs which project beyond the surface surrounding the ribs.
- Curvature is the hollow body equipped with a reinforcement. These may be, for example, a plurality of ribs or ridges that protrude beyond the surface surrounding the ribs. Thus, the supports touch the ground in the rest position with a smaller surface than in a surface without ribs. Furthermore, the ribs ensure an increase in the
- additional pins or plates may be provided on the outside of the curvature, which protrude beyond the surface of the hollow body and are connected to the hollow body by means of a plug-in, screw or adhesive connection. These additional reinforcement parts can be replaced when worn.
- the frame has two identical hollow body, each with a handle bar with handle, a support and a suspension on which the wheel is rotatably mounted. Due to the two identical hollow body, the production is facilitated.
- the two hollow bodies can either be connected to one another only by the load-receiving device or additional connecting elements can be provided.
- each of the two identical hollow body at the end remote from the handle bar a front connecting device on which the load receiving device is connected to the frame.
- the load-carrying device is a trough-shaped container
- the container is connected to the frame in the area of the wall facing forward in the direction of travel of the wheelbarrow.
- Each of the two hollow bodies has, between the wheel suspension and the front connecting device, a section designed as a rolling bar and serving to tip over a content contained in the load receiving device.
- the two rolling bars extend in the wheelbarrow in a substantially vertical direction on both sides of the wheel. When dumping the wheelbarrow is turned around the wheel forward. The weight is shifted from the wheel to the two rolling bars. Since the wheelbarrow is supported on two rolling bars, an unwanted sideways breaking of the wheelbarrow can be prevented.
- the two rolling bars can also serve to set up the wheelbarrow when not in use upright.
- each of the two identical hollow body has a rear connecting device between the handle bar and the support, on which the load receiving device is connected to the frame. If the load-carrying device is a trough-shaped container, the container is connected to the frame in the region of its wall facing the rear in the direction of travel of the wheelbarrow or in the region of its downward-pointing bottom.
- the two hollow bodies are connected at several points with the load receiver.
- the connecting device is designed as a section of the hollow body. In this section, the hollow body has a larger contact surface with respect to the remaining sections of the hollow body for the load receiving device.
- the load bearing can be supported over a larger area on the hollow bodies.
- the weight of a filled Lastenabilityeinnchtung is thus transmitted in a larger area on the frame. The power is distributed and does not work punctually. This ensures greater stability of the wheelbarrow.
- the portion of the connecting device on the side facing the Lastenameinnchtung side elevations and / or depressions has in the region facing the connecting device elevations and / or recesses which engage in the elevations and / or depressions of the connecting device.
- This can absorb and compensate not only downward forces but also laterally acting forces.
- the elevations and / or depressions are conical. Under the influence of the weight of a filled load receiving device, the elevations and depressions of the connecting device and the load receiving device engage in each other particularly well.
- the conical shape of the ridges and recesses results in an exact positioning of the load receiving device on the frame without the need for special tools. Furthermore, by the conical shape of the elevations and depressions flow of the materials of the frame and the Lastenameinnchtung is reduced or compensated when exposed to large forces. By tightening the load-carrying device on the frame by means of the elevations and indentations, this can be achieved by additional fastening. The stability and rigidity of the wheelbarrow against torsion are increased.
- the attachment of the load-receiving device to the frame, in particular in the region of the connecting devices, can take place, for example, by means of a snap-in or snap-in connection with which a section of the load-receiving device engages or snaps into a section of the frame, in particular the connecting devices of the frame.
- additional fastening means such as screws, rivets or pins can be used.
- the supports are formed as V-shaped sections of the at least one hollow body.
- the angle between the two legs of each V-shaped section is preferably between 40 ° and 80 °.
- the two legs of each V-shaped portion are connected together by a together with the legs forming a triangle spanning carrier.
- the carrier provides additional stability as it receives forces acting from above on the V-shaped section and tends to increase the opening angle of the V-shaped section.
- the carrier may be formed as a hollow body or as a profile without a cavity. It can be designed as an additional bearing surface for the load-receiving device.
- the carrier may have a load-receiving device facing flat surface on which the load-receiving device rests.
- the carrier may have, for example, an L or U shape in cross section.
- the suspension is formed as a portion of the at least one hollow body.
- the cross section of the portion of the suspension is greater than the cross sections of the adjacent sections.
- the section of the suspension has a receptacle for a fixed or rotatable axle of the wheel.
- the receptacle can be, for example, a cylindrical projection which projects in the direction of the wheel from the hollow body.
- the axis of the wheel is used. The axis is thus held on two sides by the receptacles of the hollow body. Thanks to the widened cross-section of the hollow body in the section of the suspension, there is enough space to accommodate the axle.
- the portion of the suspension on as ribs or ridges formed reinforcing elements. These are radially or at least radially outwardly from the recording of the axis or are inclined at an angle to the radial direction. They are also on the side facing the wheel of the hollow body over the adjacent surface of the hollow body. Each two adjacent ribs or ridges form two sides of a triangle. The more ribs or burrs are present, the greater the stability of the hollow body in the portion of the suspension. In addition, a high stability can be achieved by a higher wall thickness of the hollow body.
- the handles are formed as sections of the at least one hollow body in the region of the handle bars.
- the handles are designed with a recessed grip for the thumb and / or with a recessed grip for another finger, such as the index finger.
- the handles are ergonomically shaped and adapted to a user's hand.
- the surface of the handles is as large as possible, so that they fit well in the hand.
- the grip recesses for the thumb and / or another finger ensure that the handle can be held securely with the hand of a user, and the handle can not easily slip from the hand.
- the surface of the handles may be provided with a special structure or material so as to improve the feel and increase the friction between a user's hand and the handles.
- the load-receiving device has at least one elongated cavity formed as a stiffening element.
- the load-carrying device is a trough-shaped container
- a plurality of open or closed channels can be provided on the outwardly facing side of the container.
- they may be straight along or near the edges.
- two diagonally extending channels may intersect the quadrangular bottom of a trough-shaped container. This provides stability with respect to torsional forces.
- additional cavities may be provided on the load receiving device in the region of the connecting device between the frame and load bearing device.
- reinforcing elements are integrated into the load receiving device. These can be accommodated in particular in the wall sections and / or the bottom of the load receiving device during manufacture. They may be formed as ribs or ridges and project beyond the outwardly facing surface of the load bearing. In addition, they can be embedded in the material of the load receiving device such that they are not visible from the outside. Such embedded reinforcing elements may also be made of a different material than the load-bearing device. In contrast to the stiffening elements, the reinforcing elements have no cavity. They may extend, for example, along the edges of the load receiving device, or be arranged in a crosswise manner, like the ascending elements described above.
- additional reinforcement or stiffening elements can be arranged on the load-receiving device the frame during assembly of the wheelbarrow.

- one of the layers can also consist of fibers, wires or threads, which are connected together in the form of a woven or knitted fabric.
- the load receiving device comprises a foamed material.
- This may in particular be a foamed plastic.
- Foam structures in plastic are produced, for example, in the production by means of injection molding by the addition of blowing agent as an additive in the plastic melt. Furthermore, nitrogen can be injected into the hot plastic melt. Due to the foamed material, the weight of the load-bearing device is reduced without thereby reducing the stability. The strength can even be increased. If the load-bearing device has a construction of several layers, then, for example, one of the layers may consist of a foamed material.
- the frame made of plastic.
- the associated hollow body or bodies can be produced by means of fluid injection technology.
- plastic melt is introduced into the cavity of an injection molding tool and then generates a cavity by introducing a fluid into the still liquid melt.
