Description

Shopping venture

The invention relates to a shopping cart with a chassis and carried by the chassis transport container for receiving goods, which is pivotally connected to the chassis. Also described is a method for loading a trolley and a transport container carried by the chassis and pivotably connected to the chassis for receiving shopping trolleys having goods in the luggage compartment of a vehicle. Shopping trolleys are known from the prior art, which can be stowed in the luggage compartment of a vehicle, thereby avoiding the often time- and power-consuming repacking of the purchased goods. After the purchase of the goods receiving shopping cart stowed in the luggage compartment, unloaded after driving home again and the goods are stowed in the local storage.

From DE 10 2004 048 623 A1 a shopping cart is known, which can be transferred for stowing in the luggage compartment in a compact form. This shopping cart has a transport container for receiving goods and a chassis, which is pivotally connected to the transport container. For loading the shopping cart into the luggage compartment of the vehicle, the shopping cart is approximated to the vehicle such that the transport container of the shopping cart enters the opened luggage compartment and the chassis of the shopping cart at least partially enters the area below the vehicle rear. In this position is due to the purchased goods often a considerable weight having transport container on a loading area of the luggage compartment. In order to be able to pivot the chassis located below the rear of the vehicle relative to the transport container, the chassis is made foldable via a lockable articulated joint. After the operator has released the articulated joint, the chassis can be pivoted relative to the transport container up into the luggage compartment of the vehicle. This type of shopping cart has proven to be little user-friendly and also structurally complex due to the arranged in low-lying position articulated, which must be solved for pivoting the chassis relative to the transport container. It is an object of the invention to specify an operator-friendly option for stowing a shopping cart in the luggage compartment of a vehicle.

In the case of a shopping trolley of the type mentioned at the outset, this object is achieved by arranging a lifting means for lifting the undercarriage below the transport container.

By means of the lifting means, the chassis of the shopping cart can be lifted when loading into the luggage compartment opposite the roadway. Below the chassis creates a space that allows the pivoting of the chassis relative to the transport container. It is not necessary to lift the trolley manually before pivoting the chassis or first to release an articulation of the chassis. The shopping cart can be stowed in the luggage compartment in a simple and user-friendly manner.

According to a structural design of the shopping cart is proposed that the chassis has two forks. The forks may extend in particular on both sides of the shopping cart. Furthermore, the forks can be rigidly connected to each other via a transverse leg extending between the two forks.

Preferably, the forks are U-shaped and open in particular in the sliding direction. The basic shape of the forks can correspond to that of a "U", whereby the opening of the "U" can be aligned in particular to the front. The rear of the vehicle may enter the opening of the "U" as the shopping cart approaches, and the legs of the "U" may have the same or different lengths and / or may be substantially parallel. Particularly preferably, the forks each have an upper prong for connection to the transport container and a lower prong for receiving wheels. The free ends of the tines can be aligned in the sliding direction.

A further embodiment provides that the prongs are each connected to each other by a center leg, which is aligned substantially vertically. Due to the vertical orientation of the center leg results between the tines a rectangular space in which the vehicle rear of various vehicle types can penetrate.

In an advantageous embodiment of the car, the height of the transport container is adjustable in order to adapt to the height of the luggage compartment of a vehicle can. The shopping cart can thus be set individually for different vehicle types.

In this context, it is particularly advantageous if the middle leg has two leg elements, which are movable relative to each other for adjusting the height. The two leg elements can be configured telescopically and locked against each other, for example by a locking element, a locking screw, a hand knob o.a. Elements.

In a further embodiment, it is proposed that the transport container can be pivoted about a pivot axis which is arranged in the region of the upper tine. The pivot axis may be fixed to the chassis and in particular be aligned horizontally in a direction transverse to the sliding direction. To a small height of the shopping cart in the upwardly pivoted position of the landing gear, it is furthermore advantageous if the pivot axis is arranged in the region of the bottom of the transport container.

According to an embodiment which is advantageous for the pivoting mobility of the chassis, it is proposed that the pivot axis is arranged in the region of the free end of the upper tine.

In a constructive embodiment, the lower tines of the forks each have two spaced-apart wheels whose distance is adjustable, whereby the wheelbase of the chassis can be changed. The lower prong may in particular be designed to be telescopic. By reducing the wheelbase, a more compact overall shape of the shopping cart in its transport position can be achieved with loading dimensions which are more favorable for some vehicle types. This adjustment does not have to be repeated every time a load is loaded. For many types of vehicles, it is possible due to the prevailing space in the luggage compartment to set this setting once and then use the shopping cart with the appropriately adapted wheelbase. Preferably, the lower prongs of the forks each have a wheel which is pivotable from a lying on the one side of the tine driving position in a lying on the other side of the tine transport position. In the swiveled into the area above the transport container chassis can be reduced by the pivoting of the wheel in the transport position, the height of the shopping cart. By pivoting an additional reduction of the height of the shopping cart when loading in the luggage compartment of a vehicle is possible. This results in a particularly compact, favorable Verlademaße having shape of the shopping cart. Preferably, the lifting means on a lifting guide, which adds a vertical movement component when sliding along at a fixed point of horizontal movement of the shopping cart. The lifting means can slide along when introducing the transport container into the luggage compartment of the vehicle, in particular on an edge of the luggage compartment floor in the region of the rear of the vehicle. The lifting guide can be used to generate a lifting movement from a translatory sliding movement of the shopping cart. As a result, the chassis of the shopping cart can be lifted in a manner that saves energy and the required ground clearance for pivoting the chassis can be generated.

Particularly preferably, the lifting means on a slope. By tilting the shopping cart can be lifted while sliding along at a fixed point. The lifting means or the lifting guide can be designed in particular as an inclined guide.

More preferably, the lifting means extends from the front of the transport container in the direction of the center leg. When the transport container is introduced into the luggage compartment of the vehicle, the lifting means can slide along from a fixed point of the vehicle, starting from the front side of the transport container. As a result, the shopping cart can be lifted when sliding into the luggage compartment of a vehicle by sliding along the lifting means. In a further embodiment of the invention, in each case one lifting means is arranged on each fork. The lifting means may be arranged in the region of the upper tine of the fork. Furthermore, in a structural design of the upper prongs of the fork can be designed as a lifting means. In an alternative embodiment, the lifting means extends in particular plate-shaped from one fork to the other fork. The lifting means may be arranged in the region below the transport container and connected to the transport container or integrally formed thereon. The lifting means can also be designed as a stiffening element between the two forks of the chassis.

The following describes a method which, like the shopping trolley according to the invention, is suitable for achieving the abovementioned object. It is provided in a method of the type mentioned above to solve the problem that the chassis raised by means of a transport container arranged below the lifting means and then the chassis is pivoted relative to the transport container. By means of the lifting means, the chassis of the shopping cart can be lifted when loading into the luggage compartment opposite the roadway. Below the chassis created in this way a space that allows the pivoting of the chassis relative to the transport container. It is not necessary to lift the trolley manually before swiveling the trolley or to first release an articulation of the trolley. The shopping cart can be stowed in a simple and user-friendly manner in the luggage compartment.

This method of loading a chassis and a carriage supported by the chassis, pivotally connected to the chassis transport container for receiving merchandise having shopping cart in the luggage compartment of a vehicle, which is characterized in that the chassis raised by means of a transport container arranged below the lifting means and then the Chassis compared to the transport pivoted ratio is suitable for use with all of the previously described embodiments of a shopping cart according to the invention.

An embodiment of the method provides that the lifting means for lifting the chassis slides along a fixed point, whereby a vertical movement component is added to a horizontal movement of the shopping cart. When driving the shopping cart into the luggage compartment of the vehicle, the lifting means may come into contact with the vehicle. In particular, the lifting means can slide along at a point in the region of an edge of the luggage compartment opening. The lifting means of the translational movement of the shopping cart can add a lifting component.

Particularly preferred is a variant of the method in which the rear of the vehicle when lifting the chassis penetrates into the space between the tines.

An advantageous variant of the method provides that the chassis is pivoted into a lying above the transport container position. As a result of the pivoting of the chassis, in addition to the transport container, the chassis of the shopping cart can also be introduced into the luggage compartment of the vehicle. In addition, by pivoting, the overall height of the shopping cart can be reduced. This results in favorable loading dimensions. A further advantageous detail of the method described provides that the lower tine has a wheel which is pivoted after pivoting from lying on one side of the tine driving position in a lying on the other side of the tine transport position. In the upwardly pivoted position of the chassis, in which the chassis itself is located above the transport container, the height of the shopping cart can be further reduced by pivoting a wheel around the lower tine. According to a further embodiment of the method, it is proposed that the luggage compartment is designed as a trunk lying inside the vehicle or as a luggage compartment lying on the outside of the vehicle, in particular as a bicycle carrier.

Further advantages and details of the shopping cart described above and the method described are explained below with reference to the accompanying illustrations of exemplary embodiments. Show:

1 is a view of a shopping cart from behind,

Fig. 2 is a side view of the shopping cart of Fig. 1 and

3-15 different views of the shopping cart and a vehicle rear view to illustrate the processes when stowing the shopping cart in a luggage compartment in the interior of the vehicle,

16-23 different views of a shopping cart according to a second embodiment and a vehicle rear for illustrating the processes when stowing the shopping cart in a lying outside of the vehicle luggage compartment. Details of a shopping cart 1 according to the invention are first explained below with reference to the illustrations in FIGS. 1 and 2.

The shopping cart 1 has a chassis 2 and a transport container 3 carried by the chassis 2 for receiving goods. The transport container 3 is designed as a substantially cubic basket, which consists of metallic grid elements. Below the transport container 3, the chassis 2 is arranged, which is connected at its top to the transport container 2 and on its underside four wheels 10, 1 1 has.

The chassis 2 is of a total U-shaped geometry and has on both sides of the shopping cart 1 each have a U-shaped in the sliding direction of the shopping cart 1 opening fork 4.1, 4.2, which are rigidly connected to each other via a transverse connection 18. The forks 4.1, 4.2 each have an upper tine 5 for connection to the transport container 2 and a lower tine 6 for receiving the wheels 10, 11. The upper tine 5 is shorter than the lower tine 6 and extends approximately to the middle of the transport container 3. The upper tines 5 are connected to the lower tines 6 via a center leg 8, which is arranged in the rear region of the shopping cart 1 is. The middle leg 8 extends in the rear region of the transport container 2 substantially vertically from the lower prong 6 to the upper prong fifth

Due to the U-shape of the chassis 2 results in a slide-side opening, in which the rear of a vehicle when loading the shopping cart can occur, which will be discussed below in particular with reference to the illustrations in Figures 3 to 15 in more detail. As the illustrations in Figures 1 and 2 can be seen further, both the height of the transport container 2 and the wheelbase of the wheels 10, 1 adjustable by appropriate adjustment options on the chassis 2.

In order to adjust the height of the transport container 3 to the height of the luggage compartment opening of the respective vehicle, the chassis 2 is designed to be height adjustable in the region of its center leg 8. The middle leg 8 has two leg elements 8.1, 8.2, which are designed to be movable relative to each other for adjusting the height. In the manner of a length-adjustable telescopic rod, the two leg elements 8.1 and 8.2 can be moved against each other and locked by a locking element 19 in the desired height of Transportbeh ratio 3. The locking element 19 can be designed in various ways, for example as a bolt lock with a hole grid provided in the two elements and a bolt passing through the holes, as a locking screw, hand knob or the like. Elements.

In order to set the wheelbase A of the shopping cart 1, the lower tine 6 is similar to the middle leg 8 also made variable in length. The lower tine 6 also consists of two elements 6.1, 6.2, which are telescopically inserted into one another. In order to lock the two elements 6.1, 6.2 against each other, a locking element 20 is provided, which may be formed as well as the locking element 19.

In order to be able to transfer the shopping cart 1 into a compact position suitable for the transport of the shopping cart 1 in the luggage compartment of the vehicle, the chassis 2 and the transport container 2 are designed to be pivotable relative to one another. This is in the area of the free end of the upper Zinkens 5 a transversely to the sliding direction of the shopping cart 1 extending pivot axis S provided. The pivot axis S extends in the lower region of the transport container 3 or at the level of the bottom of the transport container 3. After the laden with the goods, often a considerable weight transport container 2 has been introduced by pushing the shopping cart 1 at least partially in the luggage compartment of the vehicle, can a lock 9 of the pivot axis S solved and the chassis 2 are pivoted about the pivot axis S from its driving position to a transport position in which the chassis 2 is above the Transportbe- ratio 2.

In order to pivot the chassis 2 relative to the resting in the luggage compartment transport container 3, it is necessary that below the chassis 2 is a certain amount of space available, see. Also Fig. 8. To generate this ground clearance, a lifting means 7 is provided below the transport container 3. The lifting means 7 has a designed in the manner of a slope lifting guide, which adds a vertical component of movement when sliding along at a fixed point, for example, an edge of the luggage compartment 13, the horizontal sliding movement of the shopping cart 1, whereby the shopping cart 1 is raised in a power-saving manner and the to Pivoting the chassis 2 required ground clearance is generated. The lifting means 7 extends from the front of the transport container 3 in the direction of the center leg 8. The lifting means 7 may consist of two rail-like elements, one of which is arranged on one fork 4.1 and one on the other fork 4.2. Also, the lifting element 7 may be formed as a plate-shaped element such as a sheet and extending between the two forks 4.1, 4.2. Further details of the lifting device 7 and the procedures for loading the shopping cart 1 in the vehicle interior lying luggage compartment of the vehicle will be explained below with reference to the representations in Figures 3 to 15.

Fig. 3 shows a situation after completion of the purchases, in which the basket formed as a transport container 2 is filled with goods not shown in the figures. The shopping cart 1 is located, for example, in the parking lot or in the underground garage of a supermarket very close to the vehicle 12. The tailgate 17 of the vehicle 12 is already open and releases the luggage compartment 13.

After opening the tailgate 17, a protective mat 16 lying on the loading surface of the luggage compartment 13 can first be folded or rolled out of the vehicle 1 as shown in FIG. The

Protective mat 16 is used to protect the outside, in modern vehicles 1 often painted vehicle parts from scratching while stowing the cart 1 in the luggage compartment 13. The protective mat 16 may for example consist of a carpet or felt-like material and fixed to the back of the luggage compartment 13th be connected to prevent accidental slippage.

After the vehicle 1 has been prepared in this way for the stowage of the shopping cart 1, the shopping cart 1 is pushed in the direction of the vehicle rear 14 until the position shown in FIG. 5 is reached, in which the shopping cart 1 the vehicle rear 14 via the lifting means 7 touched. As can be seen from the illustration in FIG. 5, the height of the shopping trolley 1 via the telescoping center leg 8 of the chassis 2 is adapted correspondingly to the height of the type of vehicle shown in FIG. Such a Adaptation must only be made once for each vehicle type and can then be retained.

After the lifting means 7 has come into contact with the rear of the vehicle, the shopping cart 1 is pushed further in the direction of the luggage compartment 13. In this case, the rear 14 of the vehicle 12 penetrates into the opening of the U-shaped chassis 2 as shown in FIGS. 6 and 7, wherein the lower tines 6 of the forks 4.1, 4.2 move into the area below the vehicle rear 14. At the same time the shopping cart 1 or its chassis 2 is raised via the lifting means 7. The lifting means 7 slides when pushing the shopping cart 1 forward on the upper edge of the luggage space loading area or the luggage compartment floor 21 along. Due to the inclination of the lifting means 7 of the horizontal sliding movement of the shopping cart 1 is added a lifting movement until the end position shown in Fig. 8 is reached, in which the vehicle rear 14 and the protective mat 16 rests against the center leg 8.

In this position, there is sufficient clearance between the chassis 2 and the floor in order to be able to pivot the chassis 2 upwards relative to the transport container 3 resting on the luggage compartment floor 21, cf. 9 to 11. After the upward pivoting of the chassis 2, the shopping cart 1 takes a compact Verlademaß, so that the shopping cart 1, starting from the position in FIG. 11 can be pushed completely into the luggage compartment 13 until this approximately at the Rear of a seat 22 or another boundary of the luggage compartment 13 is applied, see. Fig. 12.

In the compact transport position, the chassis 2 is located in the area above the transport container 3, so that the wheels 11, 10, the highest Make points of the shopping cart 1, cf. Should this be necessary due to the space available in the luggage compartment 13 of the respective vehicle type, the wheelbase A of the wheels 10 and 11 can be reduced to further reduce the Verlademaßes, see. FIG. 15. In addition, the front wheel 10 may be embodied such that it can be pivoted from the driving position lying on one side of the lower tine 6 into a transport position lying on the other side of the tine 6, for example by twisting the elements 6.1, 6.2 can be done. After the shopping cart 1 spent in the luggage compartment 13 and possibly the Verlademaß was further reduced in the manner described above, the protective mat 16 can be rolled up again or folded and the tailgate 17 are closed, see. 14. As soon as the driver has reached his destination, the above-described steps can also be carried out in an analogous manner for unloading the shopping cart 1 and the purchased goods can be transported with the shopping cart 1 to a domestic deposit and removed therefrom.

The above-described shopping cart 1 as well as the associated method are characterized by the fact that it is possible in a simple and user-friendly manner to stow the shopping cart 1 in a trunk 13 designed as a luggage compartment inside a vehicle 12.

It is also possible to store the shopping cart 1 in a luggage compartment 13 of the vehicle 12, which is arranged on the outside of the vehicle 12. This will be explained in more detail below with reference to FIGS. 16-23. In the Fign. 16 to 23, a shopping cart 1 according to a second embodiment is shown. This shopping cart 1 has a lifting means 7, which is arranged below the transport container 3 and formed by a arranged below the bottom of the transport container 3 plate. The transport container 3 has a counter to the sliding direction inclined bottom surface, so that the lifting means 7 extends parallel to the underside of the transport container 3. Alternatively, it would also be possible for a transport container 3 with sloping bottom, that the lifting means 7 is integrally formed on the transport container 3 and, for example, directly from the running under the transport container 3 underside of the transport container 3 is formed.

As can be seen from the illustration in FIG. 16, the vehicle 12 according to the second embodiment has an outer luggage compartment. The vehicle 12 has at the rear a trailer hitch 23, on which a designed as a bicycle carrier attachment 24 is added. Above the top 24 extends an open, outboard luggage compartment 23 of the vehicle, in which bulky luggage such. As a bicycle can be introduced.

In order to enable safe stowage of the shopping cart 1 in the outer luggage compartment 13, an adapter 25 is provided, which is connected to the attachment 24. The adapter 25 has a substantially flat loading surface which is adapted to the geometry of the shopping trolley 1 and delimits the luggage compartment 13 downwards. The adapter 25 can be plugged onto the attachment 24.

For stowing the shopping cart 1 is pushed in the direction of the luggage compartment 13 until the position shown in Fig. 16 is reached, in which the Transport container 3 touches the top 24 and / or the adapter 25 via the lifting means 7. The approach of the shopping cart 1 to the luggage compartment 13 takes place in a direction transverse to a vehicle longitudinal axis L direction Q.

After the lifting means 7 has come into contact with the bottom surface 21 of the luggage compartment 13, the shopping cart 1 is pushed further in the direction of the luggage compartment 13 and according to the illustrations in Figures 17 to 20 in an analogous manner to the previously with reference to FIGS. 2 to 14 stowed, the shopping cart in the end position shown in FIG. 19 via suitable fixing means, such as lashing or clamping means, is fixed to the position.

The illustrations in FIGS. FIGS. 20-23 show the stowage of a shopping cart 1 in an open luggage compartment 13 of a vehicle 12 similar to that previously described with reference to the illustrations in FIGS. 16 to 19 described embodiment. In contrast to the method described in connection with FIGS. 16-19, the shopping trolley according to FIGS. 20-23 is brought closer to the luggage compartment 13 in a direction L parallel to the vehicle longitudinal axis.
