Described platform 5 is made by bearing medium and/or heavy duty material, and it may be identical with the material of framework 1, and/or made by plastic material.Described platform 5 can be collapsible being resisted against on framework 1 to limit the size of described hand barrow, when it is not loaded, particularly when it is stored.
Described carrying structure is equipped with two wheels 6 for rotating of installing on same lateral shaft, so that hand barrow can move on the ground.For this reason, the supporting wheel hub 7 of each wheel 6 by the rotation of guiding wheel 6 is installed in a side and before framework 1.In a kind of modification, each wheel 6 can repeat to support larger load.In addition one or two other wheels can be installed on described carrying structure, for example, before hand barrow.
So, hand barrow can be drawn by described bicycle, draw bar 8 is mounted to move on carrying structure, particularly rotates and/or slides, and described bar has the near-end being connected with described structure and is equipped with for being connected to the free distal end 9 of the equipment (not shown) at bicycle rear portion.
Advantageously, described draw bar 8 can be made by the material that has certain flexibility and have best mechanical strength simultaneously, makes to limit especially the wheel 6 of hand barrow with respect to the lifting of the motion of described bicycle.
In shown embodiment, described near-end is mounted for the transverse rotation of carrying structure, and described near-end can be angled slightly with respect to the remainder of draw bar 8.Described near-end is installed near the transverse arm 10 between the pillar 2 that is arranged on described framework 1, and described arm can be connected to described framework or form the main portion of described framework.
In order to extend use hand barrow, connecting device is interchangeable and/or be arranged, to be connected with the rear wheel hub of seat rod and/or baggage rack and/or various bicycles, and people from cities and towns or tourist's bicycle particularly.In addition, connecting device can be connected to draw bar 8 and/or be installed in hinged way on bicycle, and hand barrow can have certain angular motion with respect to described cycle racing direction like this.
Described draw bar 8 is mounted in the sagittal plane of described framework 1, transverse rotation between the off-position against described carrying structure (Fig. 2 and 3) and control position, this control position connecting device away from described structure for the bicycle that pulls described hand barrow be connected (Fig. 1).
Therefore, described draw bar 8 is separately positioned on by bicycle and draws the control position of hand barrow and pull or store between the off-position of described hand barrow.According to shown embodiment, at described bar 8 and the framework 1 of off-position, be oppositely arranged, in order to avoid disturb loaded objects on carrying structure.
In addition, hand barrow can comprise for described draw bar 8 being remained on to the reversible locking device of work and/or off-position, can improve the coupling stiffness between hand barrow and bicycle respectively, and the caused any inconvenience of may tilting of bar described in can preventing when described hand barrow is pulled.
The motion of described draw bar 8 between work and off-position changes and is associated with the separation spacing of described wheel 6, therefore it be all arranged between the first and second given run locations, when it pulls by bicycle or by pedestrian respectively, promote advancing of hand barrow.
For this reason, by one, for making the device that described wheel moves between the first and second run locations that each wheel 6 is arranged on to described carrying structure, described device activated by the simple motion of described draw bar 8, and does not need the help of external tool.Especially, by the separation spacing being greater than at the first run location of the separation spacing of the second run location is provided, the separation spacing of described wheel 6 can be suitable for hand barrow traction mode.
Each running gear comprises two connecting rods 11, and it is held separately and is mounted for rotation and/or the first secondly connection of the revolution on the supporting wheel hub 7 of described wheel 6 that described wheel 6 is placed on to its run location on carrying structure.According to the embodiment illustrating, described mobile device is installed on loading platform 5, and described platform comprises base plate 12, in its both sides, pair of links 11 is installed.
The described connecting rod 11 of each device forms the parallelogram that points to balladeur train outside, and its deformable to make wheel 6 motions between its run location.Especially, the distortion of parallelogram is arranged like this, and in its motion process, wheel 6 keeps its service direction.
Therefore this is mounted connecting rod 11, and parallelogram distortion symmetrically in the sagittal plane of hand barrow like this makes each wheel 6 motion in the advancing of other wheel symmetries with respect in described sagittal plane.Therefore, regardless of their run location, wheel 6 still keeps symmetrical with respect to sagittal plane, guarantees the balanced distribution of optimum operation and the weight of described hand barrow on described wheel.
The actuating of each running gear rotating by described draw bar 8 realizes by linkage 13, and its top is mounted for rotation and/or on described draw bar, is connected with the revolution on connecting rod 11 respectively with bottom.The rotation that described draw bar 8 enters control position causes the lifting of linkage 13, and the rotation that described draw bar enters off-position causes the decline of described linkage.
Especially, two linkages 13 are symmetrical in the sagittal plane of described hand barrow, and the top of described linkage is mounted for rotation and/or the revolution in described draw bar 8 near-end both sides connects, and bottom is installed in respectively on the rear linking rod of running gear.This installation just can conjointly activate described running gear wheel 6 is placed on to the first or second run location, due to described wheel is placed on to run location to make up in time, thereby there is no the risk of lateral inclination.
Relevant to Fig. 1 b and 2b, the rotation that described draw bar 8 enters control position causes on the movement travel of wheel 6 the from second to first run location, and connecting rod 11 is towards hand barrow outside and relative motion below.Thereby to the movement travel of the first run location increased the separation spacing of wheel 6 and they with respect to the distance of described carrying structure to optimize the stability of the described hand barrow being pulled by bicycle.
On the contrary, when user by described draw bar 8 folding against carrying structure when placing it in off-position, the rotation of described bar is close together the wheel 6 that is arranged on the second run location.Thereby the separation spacing that reduces wheel 6 at the second run location is convenient to go-cart hand in hand, and particularly, in narrow path, the overall dimension of described hand barrow tails off.
In addition, two run locations be arranged to when hand barrow just when pulled, framework 1 facing backwards tilts to prevent that load from tumbling.When hand barrow just when pulled the lower cross member 4 of framework 1 be therefore raised, regardless of the run location of described wheel 6, and when described hand barrow is not when pulled near on the ground to form the vertical feet of hand barrow not pulling described in keeping.
In addition, for the hand barrow manually pulling, grasping member can be connected or be integrated in described carrying structure, and handle capable of being is folded described in when not used is resisted against on framework.In shown embodiment, grasping member is formed by the top cross members 3 of framework 1, and described transverse member can be equipped with the equipment of optimizing its grasping, as rubber covering.
