Description

A trolley built into the trunk of a passenger car is intended to serve customers, mainly when purchasing goods in supermarkets at all stages of the purchase from the moment the goods are selected on the trading floor, including the process of payment for selected goods and transportation by car, up to the place of consumption of the goods, for example, in the kitchen at the buyer's home

The invention relates simultaneously to the field of production of commercial equipment and the production of auxiliary accessories for cars.

It is well known that the technology of purchasing goods adopted in all supermarkets of the world consists of the following operations:

- selection and loading of goods into the goods basket provided by the supermarket, which has legs with piano-type wheels and is transported after loading by the buyer through the trading floor to the cash settlement block;

- transshipment of goods to the reception desk or conveyor cash register;

- manual reloading of goods by the cashier-operator from the receiving conveyor through the barcode reader to the output collection table of the entire set of purchases;

- calculation of the buyer with the cashier by any method available in this store;

- re-collecting the totality of purchases from the exit table to the goods basket, usually at this stage the buyer (or the store’s special employee) transfers piece purchases to prefabricated bags for the convenience of subsequent reloading from the basket to and from the trunk of the car;

- transportation of the basket from the trading floor to the car parking;

- the fourth transshipment of goods in prefabricated packages from the basket to the trunk or car interior, while the special store employee returns the empty shopping basket to the trading floor.

However, the process of transporting purchases for the buyer does not end there, since, having approached the house, the buyer again faces overload problems, and in this situation he does not have assistants in the person of the store’s full-time employees, although he also needs to:

- unload the prefabricated packages for the fifth time from the trunk and the passenger compartment and manually transfer them from the parking place through the front doors, stairs to the doors of your apartment and, finally, into the kitchen to the refrigerator. It is understood that recent operations are often impossible, or very difficult, to complete without helpers.

The described procedures are performed daily by millions of buyers, mainly women, spending all their enormous efforts and a lot of time. The economic inefficiency of the noted multiple congestion, in addition to the temporary losses of the buyer, also leads to unnecessary expenses from the trading institution, which is forced to maintain a special staff of workers (movers, extra cashiers, etc.) and bear the costs of manufacturing transshipment packages. And although all these costs are ultimately paid by the buyer, the need to use transshipment bags has far-reaching harmful environmental consequences, since natural gas is used to make bags (polyethylene), and since the bags do not decay, harmful toxic substances are released when they are burnt. It is also known that multiple congestion in packages lead to spoilage (fruit) and loss of presentation (confectionery) of products.

Thus, with the aim of eliminating multiple manual overloads of packages from the trolley to the cash register block conveyor and back to the car and from it, simplifying settlement operations and the possibility of performing the latter without the participation of a cashier, eliminating the use of additional containers (packages) to combine packages at the stages overloading them, reducing time costs and physical load on the buyer at all stages of loading and unloading goods from the car, a hand truck is proposed, which is built into the trunk of the car, which Paradise eliminates the shortcomings of generally accepted procurement technology.

The problem is solved in that the proposed trolley for collecting and transporting piece purchases in the supermarket is made in such a way that it has the opportunity to enter the boot of the car in loaded form, while its width dimensions satisfy standard aisles in the trading floor of the supermarket, and longitudinal and high-rise - the dimensions of the trunk of the car of Fig. 1, B, H, L, at the same time the trolley has a mechanism for folding the legs in such a way that they do not interfere with its entry, and the trolley has special wheels for Attacks into the trunk according to the ramps installed inside the trunk. When using such a trolley, it is possible to exclude the cashier-operator from the technological chain by transferring the mobile barcode reader into the hands of the buyer so that he can independently record his barcode in the electronic device placed on the basket at the time of selection of goods so that when upon leaving the trading floor, read the barcode file into the settlement system of the store and carry out the calculation using the settlement system adopted in this store.

The accompanying drawings show the main structural solutions of the proposed device.

Figure 6 is a plan view of the ramp (one of the guides).

Figure 7 presents a diagram of the implementation of all technological operations of procurement from the moment of removal of a piece purchase from a commodity shelf until its use in the buyer's house, where

a) loading by piece and reading the barcode of the goods,

b) connection to a payment system, input of a payment card, payment,

c) a 90 ° turn of the trolley, access to the car trunk, extension of the folding ramps and moving the trolley into the trunk,

d) transportation

d) delivery to the buyer's house, piece unloading.

The trolley of FIG. 1 will restrain the supporting body 1, on which a load basket 3 is attached using hooks 2. The guides 4 are rigidly attached to the supporting body, in which the U-shaped frame 5 slides, which is also a handle for pushing the trolley; a table 6 is rigidly attached to the frame, on which a barcode reader, a processor with a socket for connecting to the settlement system of the cash settlement unit 7, 8, 9 are fixed in the tool tray.

In addition, two shafts 10 and 11 are attached to the supporting body of the truck in the sliding supports 9, on the protruding ends of which the right and left control arms 12 and short levers 13 are connected, connected to the spring shock absorber 14, respectively, to the right and left. Four legs 15 with piano wheels 16 are installed on the shafts 10, 11, and the legs are installed in such a way that the diagonally located legs a) and b) are rigidly fixed to the respective shafts, and another diagonally arranged pair of legs sits pivotally on the shafts on the sliding sleeves 17 Each pair of legs, rigidly mounted on the shaft and pivotally attached to the shaft, on one side of the bearing body is connected using rods 18, articulating the legs 15 and the short lever 13 on one side. Four rollers 19 are mounted on the ends of the carriage on the axles rigidly attached to the bearing housing and the bearings are mounted on four bearings 19, with which the carriage with the legs folded in the niche 20 of Fig. 3 with piano wheels can roll into the trunk of the car along the ramps of Figs. 5 and 6. Two ramps - left and right - consist of two halves each 21 and 22 of Fig. 6, connected by a hinge axis 23, and pressed against each other by means of a restrained spring 24 or are locked in the hinge in the deployed position, which allows the trolley to roll in using the rollers 19 inside the trunk.

The operation of the trolley is as follows.

In the sales area, the trolley is rolled on extended legs 15 using the piano wheels 16, while the buyer pushes the trolley with the extended transport handle 5. The barcode reader 7 is used to fix each product packaging selected and put into the basket. When filling the cargo basket, the buyer approaches the settlement block and, using connector 9, connects to the settlement system of the store and inserts his plastic card, settlement is performed, a check is issued and the buyer goes to the parking lot, pushing the cart in the usual way. When approaching the car, the buyer turns the trolley 90 ° and brings it sideways to the trunk. The latter operation is necessary in order to make full use of the overall dimensions of the trunk, since in a large number of five-door cars of small and medium liter classes, usually with a sufficient trunk width, its depth is strictly limited by the back of the rear seat.

Having opened the trunk, the buyer puts forward the ramps 22 right and left, located on the gauge of the rollers 19, and locks the hinge in the ramp, after which it rolls the entire trolley onto the ramp guides, as shown in Fig. 5. After the front pair of rollers 19 rolls onto the ramp and the pair of legs comes off the ground in the front direction of the basket, the buyer turns the left lever 12 90 °, which leads to folding of the front pair of legs and their fixation in the folded position in the niche 20. With continued rolling of the trolley into the trunk, the second pair of legs detaches from the supporting surface, and in this case, the second pair of legs is folded and fixed by turning 90 ° and the trolley can be completely pushed into the trunk of the machine until it stops. Having released the hinge stopper 23 of Fig.6, the buyer fixes the trolley in the trunk and can begin to move.

Unloading the trolley is carried out in the reverse order, and the entire technological cycle of purchase and transportation is illustrated in Fig.7.

If desired, the buyer, with the help of an assistant, has the opportunity to release the hooks 2 and generally separate the load basket 3 from the carrier body 1 and manually move the basket to the desired location.
