Transport device with a preferably two-wheeled cart for buckets with liquid or bulky contents

The invention is directed to a transport device of the type defined in the scope of claim 1. Two-wheeled carts are used which have a base for depositing the buckets and can be moved over handle bars in relation to the wheels when tilted . A two-wheeled cart is used on a base to determine the resting position of the cart.

In the construction industry, transport devices are required, for example to transfer liquid ⁴ " building material in buckets between a mixer and the processing site for soil filling. Depending on the size of the construction site, buckets of different sizes are used. The buckets filled with building material are considerable in weight and therefore require a great deal of effort from the operator to load and unload the cart, although this can be made easier by tilting the cart over the handlebars. A particular problem, however, is to distribute the filling material as widely as possible over the construction site, for example when pouring soil in construction engineering. This could be done by tilting the cart in order to bring the buckets placed there into the desired incline, but this was difficult and not possible with the required dosage and distribution of the filling material.

The invention is therefore based on the task of developing a reliable, easy-to-load and unload transport device of the type mentioned in the preamble of claim 1, which facilitates the loading of the buckets and the metered removal of the contents from the buckets. This is achieved according to the invention by the features specified in the characterizing part of claim 1.

achieved measures which are of particular importance

The device according to the invention consists of three parts _that can be optionally connected to one another. It starts with a bucket that is commercially available and therefore does not need to have a specific shape. For this bucket, the invention has developed a suitable suspension gear that is an "adapter" between the given bucket and the cart according to the invention. This suspension gear is pre-assembled with the bucket to form a structural unit and produces diametrical bearing pins that protrude from the side of the bucket and determine a horizontal pivot axis. This structural unit is then assigned to a cart that has bearing recesses in its frame that complement the bearing pins. The suspension gear leaves the upper bucket opening free so that this structural unit can be filled with filling material in the usual way, like the bucket. It is recommended to use fork openings on the frame as bearing supports, as described in claim 2, which allows the bearing bolts of the unit standing on the ground to be automatically coupled. The special feature of the invention is that this unit is suspended in the cart via the bearing pins in the cart so that it can pivot, thus forming a "gondola" that can be moved into the desired inclination. There are no difficulties in transporting this gondola through the cart because the center of gravity of the suspended gondola lies below the pivot axis determined by the bearing pins inserted into the bearing support, and the stable hanging position of the gondola is therefore always achieved. At the processing location, however, the gondola can be moved into the desired inclination, whereby the filling material flows out of the bucket in a defined stream and can therefore be distributed over the entire area by simultaneously moving the cart.

A particularly simple design of the frame is achieved by the supports mentioned in claim 3, especially if their vertical alignment with the rotation axes of the wheels is taken into account. For the rotation axes of the harvester, it is recommended to use the brackets according to claim A in the frame. The required distances are easily achieved by the offsets according to claim 5. If the frame is designed according to claim 6, relatively little material is needed. FJne

Good stability and a pleasing appearance can be achieved by the hill shape in the area of the handlebars and the base according to claim 7.

For the hanging harness, it is sufficient to use only the components mentioned in claim 8, whereby a minimum of material is required. The tension bars of the sheets used not only provide a reliable connection for the bucket, but also allow buckets of different sizes to be equipped with a harness of a uniform type. The harness can be designed particularly easily according to claim 9; for very large differences in the size of the bucket, it is recommended to proceed according to claim 10, because at home you can only use one bar for a range of different buckets.

It is particularly advantageous to provide a rod on the frame of the cart as per claim II, because the desired inclination of the bucket when emptying the rubbish can be achieved by adjusting it. The simplest design of the rod consists of a pull rod as proposed in claim 12, which is controlled by an adjusting lever on the frame. The pull rod can also be coupled to the suspended gondola by simply moving the adjusting lever back and forth, if the measure as per claim 13 is used. Simple and yet reliable constructions are achieved by the measures as per claims 14 and 16. Vertical guides on the frame as per claim 17 ensure that the pull rod's coupling position is aligned with the coupling pin on the gondola, despite the ability of the pull rod to oscillate. End stops as per claim 18 prevent this. large oscillation movements of the pull rod and can be implemented most easily by means of a slotted member according to claim 19. The respective setting position of the lever can be read by means of the link according to claim 20. The adjustment of the lever can be carried out without any further steps by means of suitable clamping connections between the lever and the link. However, locking elements according to claim 21 can also be used in any fine steps, by means of which the setting position of the lever can be fixed.

Further measures and advantages of the invention emerge from the drawings and the following description. The invention is directed

The frame 21 here consists of a ring with an L-profile. Two struts II protrude from this frame 21, at the upper end 23 of which there are toggle lever locks 24 which are provided with hooks 25. When assembled, the hooks 25 overlap the upper opening edge 13 of the bucket 10, which is preferably made of plastic. To reinforce its?

has the following basic structure.

The cart 40 comprises a frame 41 with a relatively simple structure. This includes a U-bracket 42 made of tubular material, which assumes an almost horizontal position in the rest position of the cart 40 shown in Fig. 6. At the ends of the bracket 43 there are initially supports 26 pointing upwards, which are connected to a mirror image of each other.

Cranking 27 and have bearing recesses 28 in the form of fork openings 28 at their ends. These fork openings 28 are spaced apart 29 from one another, which corresponds to that of the bearing bolts 18.

At the ends of the bilge 43 there are also downward-pointing lugs 3(>, on the free ends of which the pivot axes 31 for a wheel 32 are provided. The cart 40 can be moved via the wheels 32 provided in pairs. The pivot axes Iu are, when viewed from the side of the bilge 43 in fi, essentially in the vertical plane 33 indicated there by a dot-dash line to the fork openings 28. In the simplest case, the supports 26 are therefore arranged as an extension of the lugs 36. The lugs

36 are, however, with a Z-shaped offset pointing away from each other

37 in order to ensure the distance 39 between the two wheels 32, which is desired for reasons of stability. In the frame 41, this creates a sufficiently large free space 34 between the supports 26 and brackets 36 for the pendulum suspension of the previously described structural unit 30, which will be explained in more detail below.

The cart 40 is finally provided with a pair of handlebars 35, which here also has a bow shape, is made of tubular material and is attached to the middle bow bar 45 of the aforementioned U-bracket 42. The feet 48 shown in Fig. 5 and 6 also extend from this U-bracket 42, which can also have a bow shape and, for example, according to the design of Fig. 1 and 7, can also be attached to the middle bar 44 of the U-bracket 42. The feet 48 determine the aforementioned horizontal position of the U-bracket in the rest position of Fig. 8 .

The assembly 30 consisting of bucket 10 and hanging gear 20 initially stands, as shown in Fig. 5, on the base 49, e.g. in front of a mixer, where the filling material can be filled through the bucket opening 13. Then, according to Fig. 5, the cart 40 is tilted around the wheels 32 using its handles 35 so that the fork openings 28 are aligned with the protruding bearing bolts 18. The cart 40 is then moved in this alignment, which leads to an automatic insertion of the bearing bolts 18 into the bearing receptacles 28. Then the frame 41 of the cart 40 is rotated around the wheel axles 31 in the direction of the movement arrow 45 shown in Fig. 5.

tilted. Due to the favorable leverage conditions present, the structural unit 30 is now easily lifted. To support the tilting movement, the operator can press against the aforementioned stand 48 of the cart with his foot. The structural unit 30 then swings into the aforementioned free space 34 of the frame 41 and can be moved there in an oscillating manner. The structural unit 30 in the cart 40 thus acquires the function of a "gondola" that can swing in the plane indicated by the tilting movement arrow 45. The center of gravity 38 of this gondola 30 indicated in Fig. 5 is always below the horizontal pivot axis determined by the bearings 18, 28, especially when the bucket 10 is full. This means that after the bearings 18, 28 have been coupled, the cart 40 can be moved without further ado. However, the cart 40 has an arrangement 50 for a defined inclination of the bucket located in the gondola 30, as can be seen from its effective position in Fig. f».

This tilting device 50 consists of a very simple rod, consisting of an adjusting lever 51 and a pull rod 52. In addition to the lever 51, a link 53 is attached to the frame 41 and the adjusting lever 51 is mounted there at 54. One end of the rod is hinged to the adjusting lever 51 at 55 and the pull rod 52 is therefore able to oscillate in the direction of the double arrow 56 shown in Fig. 6. A guide member 60 is attached to the frame 41, namely preferably also to the U-shaped bracket 42, which determines the vertical oscillation plane 56 of the pull rod 52 with a slot 61 and limits the width of the oscillation 56 with the two slot ends 62, 63 shown in Fig. 5.

As can be seen in Figs. T and H, the pull rod 52 has a hook 58 on its free end 57, which is simply produced by a cut in the sling unit V. This hook 58 acts as a coupling with the suspended gondola M in the following manner:

Normally, the drawbar 52 first needs to be coupled to the gondola 30. From the position of the cart shown in Fig. ii, the adjusting lever 51 is now moved forwards via its hinge 64 in the direction of the arrow 66, whereby the drawbar WL moves in the direction of the arrow 67 and thereby rotates through a force applied to the suspension gear 20.

The eyelet 46 is fastened in the lower region of the harness 20, preferably to its frame 21. The pull rod 52 has a ramp 67 at its free end 57, which facilitates the threading movement in the eyelet 46. If the incision 58 is achieved with this movement £6, then the incision 58 producing a hook is formed on the lower web 47 of the eyelet 46, whereby the coupling between the eyelet 46 and the pull rod S2 is automatically carried out simply by gravity. If the adjusting lever 51 is now moved backwards in the direction of arrow 68 in Fig. u, the pull rod 52 moves in again in the direction of arrow 69 in Fig. 6, takes the coupled eyelet 46 with it and moves the gondola 30 into a defined pendulum position, which is shown in Fig. 6, for example. As a result, the bucket 10 located in the gondola 30 is transferred to an angle of inclination 70 shown in Fig. _0. o, whereby the filling material in the flows out in the desired manner. If the cart 40 is moved, a corresponding uniform distribution of the filling material over the substrate 49 occurs.

This angle of inclination 70 can be set to a defined value by the rod 50. This can also be done continuously. To secure the angle of inclination 70, a clamping device can be provided in the area of the guide 53, whereby the adjusting lever 51 or the pull rod 52 are fixed in their respective desired position. In the present case, however, locking elements 71, 72 are used for this purpose, which also serve as marks for the position of the adjusting lever 51 to be set on the guide 53.

The locking elements 71, 72 allow a fine adjustment of the lever 51. In the present case, they consist of a group of holes 72i,i in the guide 53 and of a complementary pin 71 sitting on the locking lever 5i. It goes without saying that other locking elements known per se on levers could also be used.

As Fig. 9 and 10 illustrate, in some cases it is better to make the supports 26 variable in length in order to bring the bearing support 28 into a defined height 75 relative to the ground 49, which on the one hand corresponds to the given bucket height 73 and on the other hand to the respective attachment points 74. In this case, the filling material is

Just pick up the bucket 10 from the ground and put it down again. Then it is sufficient that when the cart 40 is tipped the cable 10 is lifted straight from the ground 49, which is why only a small amount of force is then required to operate the cart. For this purpose a support 26 designed as a separate rod is used, the lower rod section 77 of which can be moved lengthwise in a vertical guide 76 in the frame in the direction of the arrow 78. This vertical guide consists here of a sleeve 76 with a rectangular cross-section which is fastened to the U-bracket 42 and which encloses a rod section 77 of the support 26 with play. A locking element 79 is used to determine the desired extension position of the support 26, which in the present case consists of a locking element. This is inserted through cross holes in the guide rails 76 and passes through a selected hole 74 in the support, which is provided as a set of holes along the clamp and enables step-by-step adjustment, according to the desired distance height I^. Of course, such a locking pin 79 could also use teeth and a locking pawl as a locking element. Alternatively, a stepless height adjustment 75 would also be possible by means of clamps engaging the rod stack 77. Finally, instead of a rod section 77, a spindle could be used, which can be screwed into a nut fastened to the frame 41 and serves as a vertical guide.

P-- It is also possible to use a uniform suspension harness 20,

if one uses the described struts 22 and/or the frame 21 to

g and/or the bucket width 80. In the former case, the struts 22 are in

pieces that are aligned against each other to the desired length

For this purpose, slotted hole guides for clamping screws are sufficient

between the two strut lengths. It is particularly interesting to adapt the diameter 81 of the frame 21 shown in Fig. 1 to the bucket width 80. For this purpose, an open ring is used as the frame 21, the ring ends of which overlap each other and are clamped in place by means of a clamping element^.

Form ring parts.

Finally, in the simplest case, it would be conceivable to dispense with a separate suspension device 20 and to provide the relevant bearing bolts 18 directly on the bucket 10. This is particularly recommended for buckets 10 formed from metal, because the bearing rollers 18 can sit directly on the bucket wall 17.
