    Additional advantages of the invention are obtained with the features of the dependent claims.
    A shopping cart according to the invention comprises a chassis, wheels which are arranged on the chassis for driving on a surface, and a shopping basket arranged on the rear part of the chassis. The trolley is characterized in that the wheels comprise rear wheels which are arranged on the chassis, as well as front wheels which are suspended in the front part of the trolley, the chassis being height-adjustable in relation to the front wheels. The front part of the chassis is arranged to be able to be pushed in between the wheels under the chassis of a pram so that the pram can then be raised from the ground by raising the chassis in relation to the front wheels.
    With a van according to the invention, the possibility is achieved of easily transporting a pram with an accompanying child at the same time as a pram. Because the pram is first intended to be pushed in between the wheels under the chassis and then raised, the arrangement of the pram on the pram is divided into two steps, which makes it easier to place the pram on the pram.
    The front wheels can be suspended in at least one bogie, in relation to which the chassis can be raised and lowered. By placing the front wheels in a bogie, a stable front support for the Shopping Cart is obtained.
    The bogie is advantageously rotatable about an axis which is perpendicular to the longitudinal axis of the van and parallel to the ground when using the van. This facilitates travel with the shopping cart over minor obstacles such as smaller stones.
    The bogie can be rotatably suspended in at least one arm which in turn is rotatably suspended in the chassis. With such a solution, height and lowerability of the bogie is obtained in a simple manner.
    The raising of the chassis relative to the front wheels can be done by means of a pedal which is coupled to the at least one arm, which pedal is arranged to be maneuvered with the foot, and the chassis being held in the raised position by means of a locking member. By arranging the maneuvering of the raising of the chassis in relation to !! the front wheels provide a solution that allows opportunities even for relatively weak people to raise the chassis.
    The pedal may be arranged on an operating arm which is connected to the at least one arm. Such an operating arm can be connected to the at least one arm by means of a drawbar. A drawbar offers the opportunity to absorb both tensile and compressive forces and is also a relatively cost-effective solution.
    The locking member may be a lockable spring, the lockable spring being actuated by means of an actuating member, so that the chassis is arranged to be lowered by actuating the locking member. The blockable spring can be, for example, a gas spring. Such a blockable gas spring can be relatively easily blocked or opened with a valve.
    The chassis may comprise a frame in which they en n a substantially flat surface, in which frame the bogie and the rear wheels are suspended. Advantageously, a net is clamped within the framework of the formation of a loading surface. Such a frame is relatively easy to manufacture and also allows the transport of bulky goods in the event that no pram is placed on the front part of the chassis.
    The rear of the chassis may include a footrest adapted for a child to stand on. This allows the transport of two children and a pram on the same pram.
    Brief Description of the Drawings In the following, preferred embodiments of the invention will be described with reference to the accompanying drawings, in which: Figure 1 shows a perspective view of a van according to an embodiment of the present invention.
    Figure 2a shows a perspective view of the van in Figure 1 with the front wheels in a first position.
    Figures 2b and 2c show partial enlargements of the van in Figure 2a.
    Figure 3a shows a perspective view of the van in Fig. 1 with the front wheels in a second position Figures 3b and 3c show partial enlargements of the van in Fig. 3a.
    Description of Preferred Embodiments In the following description of preferred embodiments of the invention, the same reference numerals will be used for the same features in the various embodiments. The drawings are not to scale. Figure 15 shows a perspective view of a van 1 according to an embodiment of the present invention. The trolley 1 comprises a chassis 2, front wheels 3, and rear wheels 4, which are arranged on the chassis for driving on a surface, and a shopping basket 5 arranged on the rear part of the chassis 2. Both the front wheels 3 and the rear wheels 4 are arranged rotatable around axles 6 which are substantially vertical when the trolley 1 is arranged on a surface. As can be seen from Figure 1, the shopping basket 5 extends only over the rear part 7 of the chassis 2. The front part 8 of the chassis 2 is narrower than the rear part 7 of the chassis 2 to enable the front part of the chassis to be driven in under a stroller.
    Figure 2a is a perspective view of the Cart 1 in Fig. 1 with the front wheels 3 in a first position while Figure 2b is a perspective view of the Cart 1 in Fig. 1 with the front wheels 3 in a second position. As shown in Figure 2b and Figure 2c, the front wheels are maneuverable between the first position in which the front wheels are closest to the chassis 2 and a second position in which the front wheels are at a distance from the chassis. The front wheels 3 are arranged in pairs on two longitudinal beams 9 which are rigidly connected to a transverse shaft 10 which together form a bogie 11. The bogie 11 is rotatably suspended in a first arm 12 and a second arm 13, which are rotatably suspended in the base 2 about an axis of rotation 14 which is parallel to the transverse axis 10.
    The first arm 12 and the second arm 13 are operated by means of a foot pedal 16 on an operating arm 18 which is rotatably arranged in the base 2 about a second axis of rotation 19. The operating arm 18 is connected to the first arm 12 by means of a drawbar 17. The drawbar 17 is coupled to a first point 20 on the first arm 12 which is spaced from the axis of rotation and is coupled to a first bracket 21 on the operating arm 18, which first bracket 21 is spaced from the second axis of rotation 19. The foot pedal 16 is arranged to be pressed downwards for to get the front wheels 3 to the second position at a distance from the chassis 2. A lockable spring 15 is arranged between the chassis 2 and a second bracket 22 on the actuating arm 18. The lockable spring 15 acts with a force on the actuating arm 18 which is opposite a downward force on the foot pedal 16. In the embodiment shown, the lockable spring 15 is a gas spring. The shopping cart 1 also comprises an actuating means 23 with which actuating means 23 the blocking of the blockable capercaillie 15 is operated. The shopping trolley 1 also comprises a handle 24 for maneuvering the shopping trolley when traveling and a footrest 25 on which a child can stand with his upper body inside the handle 24. In the embodiment shown, the chassis 2 comprises a frame 26 on which they level a flat surface. Inside the frame 26 a net 27 is arranged on which goods can be placed. It is possible to arrange a second drawbar (not shown) on the other side of the van, which second drawbar is connected to the second arm 13 and to a second operating arm (not shown) which is rigidly connected to the operating arm 18. With two drawbars, a more even force distribution is obtained on the bogie 11 when raising and lowering the bogie 11 in relation to the chassis 2. The second control arm (not shown) is then arranged rotatable about the second axis of rotation 19.
    Figure 3a shows a perspective view of the shopping cart 1 in Figure 1 with the front wheels 3 in the lowered position. Figures 3b and 3c show partial enlargements of the van in Figure 3a.
    The function of a shopping cart 1 according to the invention will now be described with reference to the drawings. When the front wheels 3 are in the first position closest to the chassis as shown in Figure 2, the chassis is placed close to the ground on which the van is driven. The front part 8 of the chassis 2 of the van 1 can then be driven in between the wheels under a trolley (not shown). When the front part 8 of the chassis 2 of the van 1 has been placed in said position, the front part 8 of the chassis 2 of the van 1 can be raised from the floor by placing the front wheels 3 in the second position. Positioning of the front wheels 3 in the second position is accomplished by depressing the foot pedal 16. When the foot pedal 16 has been depressed and the front wheels 3 are in the second position at a distance from the chassis 2, the lockable spring 15 can be locked by actuating the actuating member 23. When the front wheels 3 have been placed in the second position, the carriage wheels have been raised from the ground. the entire weight of the pram rests on the pram 1. When the user of the pram handles their purchases, the user can thus at the same time move around his pram with accompanying children in a simple and flexible way. Another, preferably older, child may be standing on the footrest 25 at the same time.
    When the purchasing round is completed and the pram is again to be removed from the pram, blocking of the lockable spring 15 is released by actuating the actuating means 23. The lockable spring 15 will then act on the operating arm 18 so that the front wheels 3 end up in the first position closest to the chassis. 2, ie that the chassis 2 is placed close to the ground on which the van 1 is placed. The pram's wheels then come into contact with the ground again and the pram is driven away. The described embodiments can be modified in many ways without departing from the spirit and scope of the invention which is limited only by the appended claims.
    It is of course possible to let all the wheels 3, 4, on the shopping cart be rotatable about vertical axes.
    It is possible to have any number of wheels in the bogie.
    It is possible to raise and lower the front wheels in relation to the chassis in other ways than those described above.
    It is of course possible to use means other than a drawbar to couple the movement of the foot pedal to the movement of the bogie. For example, it is possible to couple the movement by means of rope wheels / sprockets and ropes / chains.
