Definitions

  • the invention relates to shopping carts as used in supermarkets by customers.
  • These shopping carts basically consist of a base frame, to which the wheels for driving the shopping cart are attached, and generally a basket for inserting the goods, which should be around the waist of the user, and one or more handles for pushing and Steering the shopping cart, the four wheels are usually all or only two of them designed as castors, so steerable about a vertical axis.
  • Such shopping carts usually consist of either metal or plastic or a combination of both materials.
  • the basket is provided with openings in whole or in part and, in particular when it is made from metal, is produced from a latticework of metal bars.
  • the rear wall of the basket can be swung open upwards and the basket of a rear shopping cart can thereby move into the basket of the front shopping cart.
  • the parts of the base frame are designed to be conical in the longitudinal direction and can therefore also be moved into one another.
  • the base frames mostly consist of pipes and the baskets mostly of wire lattice. This is disadvantageous with regard to the creation of areas for advertising, which must therefore be created in metal structures by additionally arranged sheet metal plates, slide-in frames, etc.
  • the basket can be removed from the base frame to serve as a transport box for the goods inside and, for example, to transport the filled basket away by means of a car
  • the space between the side walls is helpful in that the shopping cart can be inserted into the open tailgate Motor vehicle is driven in that the front region of the bottom of the basket rests on the edge of the trunk or is located above this edge.
  • An inclined rise of the rear wall of the basket and / or the front wall of the basket is - depending on the inclined position of the nest - only necessary to an extremely small extent for nesting. If the free, transverse rear end edge of the basket is lower in the nest position than its transition to the bottom of the basket, the rear wall that is inclined in the nest position can be used as a guide surface for pushing the next basket in.
  • this shopping cart is particularly suitable for being made essentially entirely of plastic, since the basket is made of a Except for the top, there is a completely closed one-piece trough, which already has sufficient stability even when it is made from plastic and has thin walls and a few struts.
  • the base frame can be completed from just a few individual parts and even in one piece from plastic using the injection molding process and with little subsequent assembly work.
  • the basket is made in particular in one piece and the base frame includes a first transverse connection at the front lower end in addition to the two side cheeks, and furthermore a ne second, higher and further rear cross connection, and possibly also a movable cross connection, which can be folded down in the direction of the rear lower ends of the side cheeks to guide them at their mutual distance.
  • the four wheels are mounted on the base frame, which are usually the only components on which metal is used.
  • Such a shopping cart can - without the need to fasten the wheels because of the use of standard wheels as purchased parts - also do completely without screwing during assembly and disassembly, and instead can only be assembled by means of positive connections and latches.
  • Such a shopping cart can be made from simple plastic, for example polypropylene, the plastic material also not requiring reinforcement by glass fibers or other fibers, since the structural design provides sufficient stability.
  • the second, higher-lying cross connection is designed as a support lug, that is to say an approximately horizontally extending hollow body which is located below the bottom surface of the basket folded down in the rest position and on the top of which the basket also rests in this position.
  • the support nose becomes narrower from the back to the front, both in side view and in top view, and is a hollow body which is open to the rear and which can therefore also be produced by injection molding.
  • the support lug With its front free end, the support lug reaches the front quarter of the basket and can simultaneously serve to lock the basket in this folded-down rest position on the support lug.
  • a different receiving part can be attached to the base frame instead of a shopping basket to fulfill a different purpose between the side walls of the base frame, for example a storage area, in order to Serve airport luggage trolley, or a child seat to serve as a buggy or specially dimensioned shopping baskets to serve for a specific transport purpose, for example for files in an authority, books in a library or the like.
  • the side cheeks each have a cheek beam that rises obliquely from front to back, which points with its narrow side to the front and with its broad side to the side, is a very simply shaped component that can be produced using the injection molding process or even the continuous casting process for the stability of the Decisive base frame, which additionally has a closed side surface, which does not have to be provided with openings for the purpose of weight reduction because of the small overall dimensions, and is therefore available as a continuous advertising space.
  • This advertising space can even be designed three-dimensionally during injection molding.
  • This cheek beam can also be equipped with a bone-shaped or TT-shaped cross section, in which in particular the thickened ends can be made hollow with a completely enclosed cavity, even during injection molding, using the gas injection process (GID process), as a result of which a high torsional rigidity and bending rigidity with little Material consumption and weight is achieved.
  • GID process gas injection process
  • the same method is also suitable for other parts of the trolley, for example for achieving hollow individual handles or for achieving a thickened, hollow and at the same time very stable upper peripheral edge of the basket.
  • approximately triangular-shaped cheek plates are preferably arranged below the cheek bars, in particular in the lower half thereof, which run obliquely downwards at the rear and at the lower rear ends of which the rear wheels are fastened , while a stabilizing cross connection between the cheek bars and on the other hand the front wheels are attached to the lower ends of the cheek bars.
  • the stabilizing cross connection can also be used to cover the front wheels on them Serve top.
  • all four wheels are designed as swivel castors, that is to say pivotable about a vertical axis.
  • the cheek plates also diverge slightly from the front to the rear when viewed from above. This oblique position can also be maintained in the rest position, that is to say the use position of the shopping trolley, or can be converted into a parallel position for the rest position by pivoting the cheek plates relative to the cheek bars.
  • a second fixed cross connection between the cheek beams is provided approximately in the middle of the height of the cheek beams or just below it, at least just below the bottom of the basket, which at the same time acts as the above-described support nose for the one that is folded down Basket can serve.
  • this second fixed cross connection is preferably angled, one leg of the angle running parallel approximately to the rear edge of the cheek bars and being pulled down so far that it acts as a stop for a box placed on the lower front cross connection, for example a beverage box , is used, which can be pushed back and tipped over this front lower cross connection until it rests on the second upper cross connection.
  • This tipping prevents the beverage crate from slipping forward, even when the shopping trolley brakes quickly, and without the base frame of the trolley requiring a continuous footprint for such crates.
  • the lower front cross connection can either have a rounded upper side or rollers or sliding reducing means for the beverage crate embedded therein.
  • the base frame can have a further cross strut in the lower rear region, that is to say in particular between the lower rear ends of the side plates.
  • this cross strut is not fixed, but can be moved so that it struts only in the rest position, i.e. when using the shopping trolley, the rear lower ends of the base frame or the side plates, for the nest position of the shopping trolley, on the other hand, is moved upwards, especially high can be pivoted so as not to impede the nesting of the base frames.
  • the swiveling up can be effected automatically by the next shopping trolley approaching from behind.
  • the base frame preferably has individual handles on the upper ends of the side cheeks or side bars, which preferably project upward in the plane of the side bars, in particular at an angle or in a curved manner, so that a different handle height can be selected depending on the size of the user.
  • these individual handles can be folded down in a horizontal position inwards and downwards relative to the side cheeks about a longitudinal pivot axis and should then not be located substantially above the rear upper edge of the basket.
  • the rear upper edge of the basket can also be designed as a handle bar through an opening running transversely beneath it in the rear wall of the basket. This is particularly necessary when the basket is removable from the base frame, and then preferably also in an analog form at the front edge of the basket.
  • the basket itself has smooth, continuous surfaces as far as possible.
  • the floor consists of a largely closed, continuous plate, the top of which is also available for advertising. Breakthroughs to make cleaning easier, in particular for draining spilled liquids or washing liquid, are not necessary since cleaning can be done when the nesting position is folded up.
  • the front and rear walls of the basket in particular made in one piece, are preferably formed as continuous, closed plates.
  • the side walls should have openings, which is achieved in particular in the form of parallel slits, which preferably take place parallel to the inclined position of the side bars of the basic bedrock.
  • the webs remaining between the slots thus serve as tension struts, in the direction of the loading direction of the basket side walls, when this basket is mounted in its rear region at pivot points in the base frame, which is preferably located halfway up the basket and in the middle of the width of the side walls , so that goods are preferably loaded before this suspension point.
  • the pivot axis of the basket relative to the base frame can either be designed as an axle journal between the outer surfaces of the basket and the inner surfaces of the base frame, or also as a rod-shaped pivot axis that passes through the basket interior.
  • this rod also serves to subdivide the basket, for example to hold bottles placed in the rear part of the basket, and / or as a support for an additional child seat to be attached there.
  • the child seat can be a separate part, in particular made of plastic, or can be formed by folding out individual surfaces from the rear wall and placing them on this rod.
  • the shopping cart can preferably have an enclosure device between the basket and the base frame in the rest position in order to reliably prevent the basket from swinging up unintentionally, which is hardly possible anyway when loaded due to the center of gravity.
  • the locking device is preferably automatically unlocked when two shopping carts nest into one another by means of corresponding displaceable contact elements.
  • Contact elements can serve in particular in the front area of the basket, in particular laterally outwardly projecting contact elements, in particular rollers, which roll upwards when the baskets nest into one another on the upper longitudinal edges of the basket in front and thereby pivot up the rear basket.
  • contact elements can be fastened to a lever which can be pivoted relative to the basket and can thus be used for unlocking, that this pivotable lever is connected to a releasable catch between the side cheek and the basket via a linkage, for example.
  • This further lever connection can in particular be accommodated in the hollow upper edge of the basket.
  • the unlocking can, for. B. but also by means of the existing between the side walls of the base frame, displaceable or pivotable cross bracing.
  • the rear lower cross strut of the base frame is not moved from the rest position to the nest position, however, not when this rear shopping cart is nesting, but only when the next shopping cart approaches from behind. Activation by the shopping cart in front of it would also be possible and could then serve to deactivate the locking between the basket and the base frame when nesting. Otherwise, the same contact elements, in particular contact rollers, which serve to guide the basket of the rear shopping cart when nesting along the front shopping cart, are preferably used to deactivate the locking device.
