Description

The innovation relates to a stackable shopping cart equipped with a braking device in which a die Goods receiving basket is arranged at a distance from the chassis, with a at the rear end of the basket Handle is located on both sides with a brake linkage

is connected, which via spring elements for non- ■

use of the shopping cart automatically brakes'

causes the rear rollers of the shopping cart, while '■

when using the shopping cart by swiveling the |

The brakes of the shopping trolley are released with the handle down and the same shopping trolley located in front in the stacking association via a stop mechanism acts so that the brakes of the shopping trolley ahead are released.

Shopping carts of this type are used when, for example Gradients have to be overcome inside or outside self-service shops. It will especially putting down or pushing single or multiple shopping carts stacked in a row made difficult by this gradient. To the stand Transport and shopping trolleys equipped with automatic braking devices are therefore now part of the technology are, which are effective both when pushing and parking as well as in the stacking association of the car.

So the DOS 23 50 173 describes a preferred on train stations trolleys used to transport luggage,

the brakes by pressing down the handle the rear rollers are released, with the trolley having a stop at the rear end of the chassis, which has the effect that when two trolleys are pushed into one another, the rear car takes over the front car Raises area of its rear rollers and so cancels the braking effect of the front car. As a disadvantage must be stated that a relatively large force must be used to each of the trolleys to push up the inclined plane arranged on the chassis and push them into one another.

In U.S. Patents 2,958,537; 3,952,111 and 3,458 OI5 shopping carts are revealed, the brakes of which are probably stacked are released by themselves through the action of a stop mechanism, but all of these in addition to the usual handle have a further handle which must be moved when the shopping cart or trolleys are to be pushed. A disadvantage of these shopping carts is that when they are pushed into one another, the brake linkage, which in some cases protrudes in a disruptive manner, and the handle that triggers the braking move must be, so that there is a risk of accidentally pinching your fingers between either the handle and the handle or between the brake linkage and the trolley linkage, the shopping trolley usually made of wire exists. All this risk is particularly prevalent when, as is usually the case, two shopping trolleys are pushed into one another with both hands are, as is well known, each with a car

one hand each.

The task of the innovation is therefore to create a shopping cart to create of the type mentioned, in which the stop mechanism is arranged so that the danger the jamming of fingers between mutually movable parts during the stacking process in any case It is excluded that the parts belonging to the stop mechanism are arranged on the shopping cart in such a way that they do not protrude from the shopping trolley in a disruptive manner, and that when several shopping carts are stacked, the roles of all the carts remain on the ground.

The object is achieved according to the novelty in that the stop mechanism by a cross bar connecting the two brake rods in the area between the chassis and the basket and by at least one stop arranged between the two support arms in the area between the chassis and the basket is formed.

It has proven to be advantageous in terms of the innovation that the stop mechanism outside the grip area of a Person on the shopping cart is arranged that a disturbing Individual parts forming the stop mechanism do not move away due to their advantageous arrangement below the basket, and that the stacked shopping carts are not lifted off the ground with their rear ends.

The innovation is explained in more detail using the drawing.
Show it:

Fi. g 1 in a view of the rear end of the shopping cart and in a side view the stop mechanism and

Fig. 2 shows the lifting process of the brake linkage when telescoping two shopping carts in a schematic way.

1 shows the shopping trolley 1, consisting essentially of a chassis 2 and a basket k arranged at a distance from the chassis 2 and connected to the chassis 2 by support arms 3. At its rear end, the basket k has a handle 5 which is connected to the basket k on both sides via webs 7 and is mounted so as to be movable about a horizontal axis. A brake rod 8 is attached to each of the webs 7. Both brake rods 8 lead at a small distance along the basket 4 and the support arms 3 to the rear rollers 6, which can be designed as swivel or fixed rollers. By adding two compression springs 9 to the brake rods 8, it is achieved in a known manner that the brakes 10 are fully effective when the shopping trolley 1 is in the rest position. If you want to push the shopping cart 1, the brakes 10 must be released by pressing down the handle 5. In order to keep the brakes 10 of the individual shopping trolleys in the released position in the stacking association, a horizontally arranged cross bar 11 is expediently provided below the basket k , which connects the two brake rods 8 to one another. Furthermore, at least

a stop 12, expediently as a Loop formed provided, which is arranged between the basket 4 and chassis 2 so that when telescoping several shopping carts 1, 1 ', according to FIG. 2, the upper limit 13 of the stop 12, the cross bar 11 'of the preceding shopping trolley 1 'drives under and him pushed up so far that the braking effect is canceled via the two brake rods 8 'connected to the transverse rod 11' will. The stop is advantageously on the inside a support arm 3 attached so as not to interfere with the stacking of the shopping carts 1, 1 '. One solves the last shopping cart 1 from a stacking association, see above the two brake rods 8 'of the one ahead Shopping trolley 1 'by means of the two compression springs 9' pressed down. The now last shopping cart 1 'remains now by itself in a braked position.

Of course you can use either rod-shaped or double-rod shaped Provide support arm 3 with a stop 12. In the same way it is possible to below the basket 4, on the basket 4 itself or, for example, on a cross member 14 supporting the basket 4, at least one stop 12, which would have to fulfill the same function as those just mentioned. Furthermore, the cross bar 11 can through at least one, but preferably two, attached to each brake rod 8, located on the same axis as the transverse rod 11 Bolts 11a should be replaced if the stiffness of the brake rods allows this.
