Definitions
- the present invention relates to a transport trolley, in particular a shopping trolley, comprising a basket-like goods container whose base area can be changed.
- a transport trolley of the type specified above is known for example from German patent 4417418.
- Another generic transport wagon has become known through public prior use by Wanzl Metallwarenfabrik GmbH, Leipheim.
- the basket-like goods container is designed so that its capacity changes according to the base. With a small footprint, the basket-like goods container has a small capacity, but with a large footprint, it has a large capacity.
- a transport carriage of the generic type has the following features: a container part has a bottom, two side walls and a rear wall; a border part has an end wall section and two side wall sections; the border part and the container part are relative to one another by means of a guide device between a first position in which the Side wall sections of the border part extend the side walls of the container part to the front, and a second position in which the side wall sections of the border part extend the side walls of the container part upwards; a surface element is between a first position assigned to the first part of the border part to the container part, in which it closes the bottom part of the border part in the form of a base element, and a second position assigned to the second position of the border part to the container part, in which it forms the container part in the form of an end wall element closed at the front, changeable.
- the basket-like goods container of the trolley according to the invention thus has four main components, namely a container part, a border part, a guide device and a surface element.
- the container part has, as is also the case for the known generic transport vehicles, a base, two side walls and a rear wall.
- the border part comprises only one end wall section and two side wall sections, but not a bottom section which is fixedly connected to the side wall sections and the end wall section.
- the border part or the container part can be displaced relative to the respective other part between a first and a second position, the border part extending the container part forward in its first position and upward in its second position.
- the surface element has a different function depending on the position of the border part relative to the container part.
- the surface element for the border part forms a base element in that it closes the border part below; in the second position of the border part relative to the container part, the surface element forms an end wall for the container part by closing it at the front.
- the container part can be designed to be stationary and the border part can be changed in position, the border part can be fixed and the container part can be changed in position, or both parts can be changed in position.
- the invention is explained below on the basis of a design of the goods container with a stationary container part and a position-changing border part, this is done only by way of example and is not associated with any restriction of the protection to such a design.
- the transport trolley according to the invention is characterized in that the basket-like goods container can take two different formats, namely a landscape format (first position of the border part and the surface element relative to the container part) and a portrait format (second position of the border part and the surface element relative to the Container part).
- the capacity of the goods container is essentially the same in both formats regardless of the different footprint.
- the surface element is connected in an articulated manner to the - in this case position-changing - border part in the region of the lower edge of its end wall section.
- the surface element is coupled to the border part in a particularly simple and robust manner, so that the displacements of the border part and of the surface element relative to the container part are forcibly coupled from their respective first position to their respective second position and vice versa.
- the surface element hangs down from the end wall section of the border part in front of the stationary container part in order to close the front of the stationary container part.
- the guide device of the basket-like goods container of the trolley according to the invention can be designed in various ways from a technical construction point of view.
- the guide device comprises a parallel link arrangement.
- This further development of the invention is in turn characterized by a low manufacturing outlay with high robustness and user-friendly handling.
- the surface element can be functionally integrated in a particularly preferred manner Integrate the guide device by being part of the parallel link arrangement.
- the surface element itself can represent one of the parallel links.
- the pivot bearing for the surface element can lie in its plane or at a distance from it, in which case the surface element is supported on the pivot bearing via support elements.
- the guide device can comprise a linear guide arrangement.
- the surface element can in turn be connected in an articulated manner to the border part in the region of the lower edge of its end wall section.
- a sliding guide arrangement for the surface element is particularly preferably arranged in the region of the lower edge of the end wall of the stationary container part.
- a guide device is a combined handlebar and bow guide arrangement, as will be explained in greater detail below.
- Yet another development of the present invention is characterized in that the rear wall of the (stationary) container part protrudes upward over the upper edge of the side walls of the container part.
- the rear wall of the container part can extend up to the upper edge of the side wall sections of the (position-changing) border part in its second position. In this case, the goods container is too when the border part is in its second position, completely closed on the back.
- the terms “rear wall”, “side walls”, “side wall sections” and “end wall section” only refer to the basket-like goods container as such, but do not define its orientation on the transport trolley.
- the present invention is not limited to transport trolleys in which the basket-like goods container is mounted so that its rear wall faces backwards and its end wall section faces forward.
- the goods container can for example also be rotated by 90 ° or 180 ° on the trolley, so that its rear wall to one side and its end wall section to the other side or its rear wall to the front and its front wall section to the rear.

- FIG. 8 a side view an eighth preferred
- Embodiment of the goods container usable within the scope of the present invention.
- the goods container illustrated in FIG. 1 comprises a stationary container part 1 with a bottom 2, two side walls 3 and 4 and a rear wall 5 and a - in relation to the stationary container part 1 - position-changing border part 6 with an end wall section 7 and two side wall sections 8 and 9.
- the side walls 3 and 4 of the stationary container part 1 and the side wall sections 8 and 9 of the border part 6 are substantially the same size and have a substantially square format.
- the stationary container part 1 and the border part 6 are connected to one another via two links 10 and 11 and a surface element 12.
- the two links 10 and 11 on the one hand and the surface element 12 on the other hand form a parallel link arrangement which ensures a parallel displacement of the border part 6 relative to the stationary container part 1.
- the surface element 12 is articulated both with the lower edge 13 of the end wall section 7 of the border part 6 and with the front edge 14 of the bottom 2 of the stationary container part 1.
- the two links 10 and 11 are each on the one hand in the area of the upper rear Corner of the side walls 3 and 4 of the stationary container part 1 and on the other hand hinged in the area of the upper rear corner of the side wall sections 8 and 9 of the border part 6.
- the end wall section 7 of the border part 6 is slightly wider than the rear wall 5 of the stationary container part, so that the clear width between the two side wall sections 8 and 9 of the border part 6 is slightly larger than the external dimensions of the stationary container part 1.
- the side wall sections 8 encompass and 9 the side walls 3 and 4 from the outside, in particular in FIG. 1b, which shows an intermediate position of the border part 1 and the surface element 12 between the respective first position (FIG. 1 a) and the respective second position (FIG. 1 c), is removable.
- FIG. 2 illustrates the implementation of the basic structure described above, shown in FIG. 1, on those goods containers in which the stationary container part and the border part have flatter proportions than the embodiment shown in FIG. 1.
- the central difference between the goods container according to FIG. 2 and that according to FIG. 1 is that the surface element 12 is not articulated on the end edge 14 of the bottom 2 of the fixed container part 1, but rather on a fixed pivot bearing located away from that edge.
- a support element 16 is firmly connected to the surface element 12, the free end of which is mounted on the rotary bearing 15.
- the pivot bearing 15 is arranged in this case and the support element 16 is dimensioned such that the surface element in its first position (FIG. 2a) covers the bottom 2 of the
- the stationary container part is extended to the front, while in its second position (FIG.
- the articulation points 17 and 18 of the handlebar 10 on the stationary container part 1 and the border part 6 correspond to one another in terms of their position relative to the position of the pivot bearing 15 and the articulation point 19 of the surface element 12 on the border part 6, the articulation point 19 in the region of the lower edge of the end wall section 7 of the border part 6.
- FIG. 3 illustrates, likewise in three positions, a goods container in which the guide device used to guide the border part comprises a linear guide arrangement 20.
- the border part 6 is guided in a straight line.
- the surface element 12 is articulated to the border part 6, the articulation point 19 again being arranged in the region of the lower edge of the end wall section 7 of the border part 6.
- a sliding guide arrangement 21 for the surface element 12 is arranged on the linear guide arrangement 20 in the region of the front edge of the bottom 2 of the stationary container part 1.
- This sliding guide arrangement 21 supports the surface element 12 and holds it forward in its first, the bottom 2 of the stationary container part 1 extending position (Fig. 3a) or its second, the stationary container part closing position at the front (Fig. 3c). If the border part 6 is moved from its first to its second position or vice versa, the surface element 12 slides on the sliding guide arrangement 21.
- the surface element and / or the border part in its first position can be supported on stationary supports, in particular on the supports carrying the goods container as a whole and the sliding device of the transport vehicle in question can be attached.
- This is favorable from a static point of view. It is also favorable from a static point of view if, in its first position, the border part 6 rests with suitable projections on stops which are arranged on the stationary container part, in particular in the region of its upper front edge.
- the goods container illustrated in FIG. 4 differs from that according to FIG. 1 essentially only by two features.
- the guide device does not comprise a parallel link arrangement, but rather a combined link and bow guide arrangement.
- the handlebar is in turn formed by the surface element 12.
- each of the two side wall sections 8 and 9 of the peripheral part 6 is assigned an arc guide 22, in which a pin is slidably guided, which is attached to the associated side wall 3 or 4 of the container part 1 .
- the rear wall 5 of the container part 1 is of a lower height than in the case of that shown in FIG. 1 Goods container, which affects the accessibility to the goods container from the rear.
- the comparison of FIGS. 1 and 4 illustrates particularly well that it is not important for the implementation of the present invention whether the container part is stationary and the bordering part is changeable or the container part is changeable and the bordering part is stationary.
- the container part 1 and the border part 6 are pivotable relative to one another connected.
- the guide device is formed by the two joints 23, which define a pivot axis 24.
- the border part 6 can be pivoted relative to the container part 1 about the pivot axis 24 by an angle of 180 ° (arrow A).
- the surface element 12 is in turn articulated to the front edge 14 of the bottom 2 of the container part 1.
- the surface element 12 is connected in an articulated manner to a wall element 26, which in turn is connected in an articulated manner to the side wall sections 8 and 9 of the border part 6.
- the articulated connection of the wall element 26 with the side wall sections 8 and 9 of the border part serves two joints 27 which define a pivot axis 28.
- the pivot axis 28 is parallel to the pivot axis 24 and the pivot axis of the articulated connection of the wall element 26 to the surface element 12. It is essential that in the first position of the border part 6 illustrated in FIG. 5a relative to the container part 1, the surface element 12 and the wall element 26 can be folded against one another in a flat contact, so that these two parts together extend the bottom 2 of the container part to the front, to close the border part in the form of a bottom element at the bottom.
- the folded unit comprising the surface element 12 and the wall element 26, is supported along the edge defining the joint connection on stops (not shown) which are arranged in the region of that edge 29 of the end wall section 7 of the border part 6, which is in the first position of the border part (Fig. 5a) is below.
- a particularly interesting aspect of the goods container illustrated in FIG. 5 is that the two side walls 3 and 4 of the container part 1 and the two side wall sections 8 and 9 of the border part 6 can have the same distance from one another, so that the clear width of the border part 6 of the clear width corresponds to the container part 1. Furthermore, due to its specific connection of the border part to the container part, this goods container is characterized by a particularly high level of robustness.
- the bottom 2 of the container part 1 has a smaller extent than the side walls 3 and 4 of the container part 1.
- the side walls 3 and 4 of the container part protrude forward over the bottom 2.
- the end wall section 7 of the border part 6 is not arranged vertically but instead rather inclined, as may be desirable for aesthetic reasons.
- the basic characteristics of the goods container shown in FIG. 7 correspond to those of the goods container according to FIG. 1.
- the main difference here is that the bottom 2 of the container part 1 is larger than the surface element 12.
- This has the consequence that the base area of the goods container when the border part 6 is in its first position (FIG. 7a) is not twice as large as the base area of the goods container in the second position of the border part 6 (FIG. 7c). Rather, it can be provided, for example, that the base area of the goods container can be increased by changing the position of the border part 6 from its second position to its first position by approximately 60%. Any other relationship is also conceivable.
- the goods container illustrated in FIG. 8 corresponds to the goods container according to FIG. 2 with regard to essential design features.
- a rotary slide bearing 30 is provided instead of the rotary bearing 15 according to FIG. 2.
- This comprises the guide loops 31 assigned to the surface element 12 and the associated counter bearings 32.
- the guide loops 31 are guided on the stub axles 33 of the counter bearing 32 so as to be displaceable and rotatable.
- An advantage of this embodiment over that according to FIG. 2 is that the counter bearing 32 can be arranged in the region of the lower front edge of the container part 1, where it interferes less with certain transport trolley designs than at a greater distance from it Container part 1 arranged pivot bearing 15 of the goods container illustrated in FIG. 2.
- a support 34 of the border part 6 on the container part 1 is additionally illustrated schematically in its first position.
- a bolt 35 arranged in the region of the upper rear edge of the border part 6 engages in a hook-shaped receptacle which is arranged in the region of the upper front edge of the container part 1.
- Other designs and other arrangements of the support are conceivable.
