The innovation relates to a stackable shopping cart according to the general term of the main claim.

In a known shopping trolley, the longitudinal beams of the chassis are formed in sections by at least two strong wires or rods arranged one above the other, whereby the section of the longitudinal beams which is formed by only two wires and which is located in the front area of the trolley is simultaneously intended as a guide for a movable shelf located under the basket and which is inclined forwards in this position. The shelf has a support section on both sides at its front end, whereby each support section is guided in a guide so that it can move. The ability of the shelf to move forwards is limited by a cross-connecting part which connects the longitudinal beams and is located in the front area of the chassis and which serves as a stop for the shelf. The cross-connecting part is designed as a straight rod which is arranged between the wires of the longitudinal beams and is connected to them. Another U-shaped cross-connecting part arranged at the front, which also connects the longitudinal beams, is intended to carry the front castors.

The aim of the innovation is to either dispense with the cross-connecting part, which serves as a front stop for the shelf, for cost reasons, or to place it somewhere else where it does not perform a stop function, whereby the limited mobility of the shelf must be retained.

The problem is solved in a novel way in that the crossbar forms a stop to limit the displacement of the shelf into the non-object position.

Now, a shopping cart is known from the German utility model G 85 00 639.4 that has a shelf that can be swung out to the rear for storing larger objects.

In contrast to the generic shopping cart , the shelf on this shopping cart is suspended from two struts that lead upwards to the handle and are pivoted there about a horizontal axis. When in use, the shelf rests on a bracket (sb) underneath the basket. When not in use, a large part of the shelf ^'s air surface is also underneath a front cross-connection, which is not shown in the utility model mentioned, but is provided for in shopping carts of this type that have since come onto the market. Finally, the shopping cart mentioned differs from the generic shopping cart primarily in that there are no guides for the shelf on the longitudinal beams of the chassis.

A shopping cart with a rear shelf is also known from European patent specification 0 349 23. In contrast to the proposed new shopping cart, the chassis of the shopping cart in question consists of a trapezoidal base frame, at the rear end of which two supports are directed upwards on both sides to support the basket. A shelf equipped with lateral guides is suspended from two crossbars connecting the supports, through which the crossbars are guided. This shopping cart also has no guides on the longitudinal beams and the level of its loading area, if you follow the drawing, extends forwards below the front cross connection of the chassis.

The advantage of the innovation is that when the shelf is not in use, its handle-side cross-connection hits a stop on the chassis. This means that the previously usual front cross-connection part that performs a stop function can be dispensed with, which reduces manufacturing costs.

The innovation is explained in more detail using a drawing This shows the purchasing department in detail, nin in Shi

narrowing, i.e. conical chassis 2, which carries four rollers 11. A basket 12, also conical in shape, is preferably arranged stationary on the chassis 2, the rear wall 13 of which is pivotally mounted about a horizontal axis in a known manner, so that shopping trolleys 1 designed in this way, as well as those shopping trolleys 1 whose baskets 12 can be pivoted upwards, can be pushed into one another, i.e. stacked, in a space-saving manner. A sliding arrangement 14, for example in the form of a handle bar, is provided at the rear end of the basket 12. The chassis 2 is formed by two longitudinal beams 3, which are connected at the front by at least one cross-connecting part 15, preferably made of flat steel. The longitudinal beams 3, designed in a known manner essentially as upwardly curved parts, are also connected to one another in their upper region 4 by a crosspiece 20. The longitudinal beams 3 expediently consist of two bars or wires 8 arranged one above the other, which are each welded in sections by connecting parts 9, ^91, for example steel balls or spacers. This creates a guide 7 inclined in the sliding direction at least in the front area 5 of each longitudinal beam 3. A finger-like support section 22 is guided in a sliding manner in each guide 7, each support section 22 belonging to a shelf 21 which, in the non-use position, is mounted so that it can be slid between the longitudinal beams 3 along the sliding direction of the shopping trolley 1. Opposite the support sections 22, the shelf 21 is supported in a known manner with its other end 23 on the correspondingly shaped crosspiece 20, which also forms lateral guides, so that the shelf 21 can be moved from the non-use position, as shown, into a use position (dash-dotted representation) and back again, see arrow. In the position of use, the shelf 21 is supported by its outer longitudinal bars 24, which are connected at the end by a cross bar 25, on the crossbar 20 and by its support sections 22 in the two guides 7. The same applies to the non-use position, where the cross bar 25 rests against the crossbar 20, so that a

Stop is formed to limit the ability of the shelf 21 to move forwards, i.e. into the non-use position. The support sections 22, on the other hand, rest only in the guides 7; they do not abut any stop part that could be located on or in the guides 7. When the shelf 21 is in the use position, the support sections 22 can rest on connecting parts 9' which are arranged between the wires 8 and close to the crosspiece 20. As is well known, when the shelf 21 is not in use, at least the largest part of a plane 27 which is identical to the loading surface 26 of the shelf 21 is located above the cross-connecting part 15 and above a further cross-connecting part 15' indicated by ^a dash-dot line, which can be provided, for example, for stability reasons on the front area 5 of the chassis 2 and connects the two longitudinal members 3. However, the cross-connecting part 15* krnn can also preferably be omitted.
