Description: COMPUTERIZED SHOPPING CART WITH STORAGE AND DISTRIBUTION SYSTEM, FOR SUPERMARKET USE Introduction and fields of application The present invention relates to a computerised cart able to be articulated into mechanical cart and electronic (product) entering unit, with storage / distribution system thereof, and which provides the following services: elimination of queues at the check-out counters; information on the products available for sales, emission of multimedia commercial messages, market search in real time, pastimes, it comprises at its base a new type of mechanical cart to contain products, parked outdoors, and which is interconnected (when entering) / disconnected (before leaving) automatically, by the distribution/storage system to a computerised product insertion unit; this comprises a compartment for the inlet of products and a computer of new design aimed at managing shopping problems, called SHOPPING-COMPUTER which also coordinates all other process electronic functions (compartment opening, closure, checks and more). The fields of application are supermarkets, in particular in food product areas. It offers the following basic services: interactive information about the shopping scenario (list of products for sale, on sale, location on the shelves, other information), about the products being purchased (price, whether they are on sale, other information) or already purchased (list of products already bought, or other information); or to be purchased (shopping list); computerised guide within commercial areas managing purchase operations so as to eliminate check-out queues (fundamental service). The shopping data collected are conveniently sent to the cash register for the emission of the receipt, avoiding the need to off-load the items. It also offers other tradable supplementary services: during shopping operations it performs an intelligent multimedia commercial service (the same commercial message repeated a few times, for instance after the shopper has entered a product competing with the sponsor's); real-time market research service (with prizes, on the type of consumer, on the product, or other information) entertainment service (quizzes with prizes or of some other kind). Therefore the fields of application are: in supermarkets (of medium / large size) groceries area. The services offered are: basic service for the elimination of queues at the cash register, shopper guide; tradable auxiliary commercial message service (the same for all carts) of great effectiveness for food products, interesting for advertising firms; market research service (on-line) in real time or (off-line) on diskette, interesting for marketing firms; pastimes service, for various applications: (entertainment, promotions, or others). Prior art Currently, in supermarkets, shopping information are provided with a myriad of signs and are generic (they indicate the various departments: detergents, others); the mechanical cart is used for shopping, the prices of products on sale are reported on physical tags, which oftentimes even go missing. At the cash register, all products must be removed from the cart to be counted with the manual optical scanner by the operator. Lastly, there is a form of advertising on signs aboard the cart. There is no possibility of qualifying shopping data with the consumer's characteristics (age, profession, other information) for market research purposes. Current drawbacks. The current information service is scattershot, generic, and it engenders only confusion. Moreover, it is not interactive and hence it fails to meet precise requests by the customer (where is the cheese? or other requests). The result is that a synthetic presentation of the shopping scenario cannot be provided, so much so that, especially in large shopping areas, many departments remain unknown, and it is difficult to reach the desired product, or the shopper gives up on the purchase. While shopping, it is often impossible to understand the price of the product, or whether it is on sale, because there was no time to update its price tag due to the innumerable daily variations. Moreover, in order to calculate the total amount as it increases, calculators are used. At the check-out counter, long queues are formed of shoppers waiting for the receipts to be issued. Lastly, the on-board commercial message is almost ineffective. The data for each shopping cart cannot be qualified with the customer's data (age, profession, other information) and hence they are not useful for the purposes of a specific market research about consumers (identifying the stereotype consumer for that product). Advantages of the invention The computerised cart can access a highly powerful (millions of data items) data base about all products on sale, able to present both a synthetic overview of all products on the shelves (general list of the products for sale, on sale, location, price or other information), or of the products being purchased (price, whether they are on special offer, total amount) or already purchased (the list of products already purchased), and then through interaction with the SHOPPING-COMPUTER (on- board unit) it rapidly meets specific requests (where is the cheese? which products are on sale) even varying widely (what are the beauty products? what foods are allowed for that disease? On which shelf? and more). It is proposed as a discreet, personal guide within large shopping spaces. At the check-out counter it allows the cash register to issue the receipt immediately, with no need to check out the products: this eliminates long queues. Moreover, the on-board multimedia commercial message (audio, graphic video/drawings) is very effective because it is a novelty, it is modern, it is not annoying (3/4 times while shopping) and it is emitted in an ideal context (while shopping) at strategic times (after the shopper purchases a product similar or in competition thereto). Lastly, it allows to perform real-time market research through questionnaires which can be activated from the SHOPPING-COMPUTER keyboard by the consumer him/herself with appropriate incentives (souvenirs or others). In particular it allows to qualify the data of each shopping cart with the characteristics of the consumer him/herself (age, profession), whilst safeguarding his/her anonymity: this makes them useable for a global review within a research about consumption (who consumes that product? in what quantity? or other information) Inventive concept of the invention These objects and others besides are attained by the computerised shopping cart able to be articulated into mechanical cart and computerised unit for entering products, with system for the storage and distribution thereof, with services of check-out counter queue elimination, shopping information, emission of commercial messages, real-time market research, pastimes and related auxiliary services for use in supermarkets (groceries area) characterised in that in general it comprises a closed/openable mechanical cart compartment (1) of new design for food products able to be hitched / unhitched through related electromechanical system (19) to the computerised unit for entering products (5), such as to avoid any contact with the interior environment and it checks shopping operations for correctness moreover the electronic unit (6) housed therein, comprises a computer of new design aimed at shopping problems called SHOPPING-COMPUTER (6), with related data base 6d, operating software (16) and firmware (17) for controlling the process of the related parts, in particular the mechanical cart comprises a department (lc2) for containing the inserted products, closed & openable by a related system (4) so as to be able to latch together; it comprises an automatic system (2) for varying (increasing) its internal capacity; an attenuator distributor (3) of the products as they are inserted; the insertion unit (5) comprises a manual mechanical system (5a) for inserting/ejecting the products toward the interior of the container and a series of electronic systems, i.e. the automatic system for optically scanning (7) the standard bar-codes UNIVERSAL PRODUCT CODE (UPC) / EUROPEAN ARTICLE NUMBERING (EAN), one (8) for checking the correctness of the shopping operation, one for the exchange of messages of any nature and form (9, 10, 11), one (12) for emitting multimedia commercial messages, one (13) for market research, one (14) for pastimes, one (15) for power supply; one (25) controlling the removal of the insertion unit; the mechanical cart is parked free outside, whereas insertion units are distributed (at the entrance) and stored (before departure) by the auxiliary automatic distribution / storage system (20); it comprises the central system (22) (data exchange via ether / shopping data concentrator, control over cash register (22f) for receipt issue, control over storage / distribution system) (20); it comprises the automatic payment (self-service) counter (23); moreover within the aboard unit it comprises the computerised map (24) of product distribution on the various shelves, aided by orientation units (position co-ordinate) installed within the commercial area, and related orientation units (position co-ordinates).

Operation The metal cart 1 is parked in the outside area, whilst the product insertion units 5 are inside within the automatic storage distribution system 20. The arriving customer draws the metal cart, enters and immediately after the entrance moves it close (drive side) to a position of the distribution station 20a for the automatic latching of the insertion unit. To facilitate this manoeuvre, the cart follows appropriate guides. Once latching is complete, an appropriate message (acoustic, visual, or of other type) is sent to the customer together with a welcome message. Essentially, the ground unit 22 detects the event upon communication via ether (infrared) of the on-board unit 6 which has latched it, unlocks the holding device 20a2. Then the insertion unit performs a full self- starting operation, the main platform 3b automatically goes into shopping position (top) and an appropriate message (wishing good shopping) informs that it is ready for shopping. Operating on the keyboard 6f, information can be requested on the products exposed (list menu: general, sales, purchased, others or about those to be purchased) or compose the shopping list thanks to a specific procedure; in general the display keys allow to examine individual pages, within a list / survey / pastimes, whilst when operating in the general list environment (index) the selection keys are used (pointing at the line with blink + run) to point and choose the desired argument (lists / survey / pastimes / desired page); to shop, it is necessary to introduce the product into the inlet compartment through the door 5a2, with its label visible upward, to the optical scanning device 7a, and positioned within a band parallel to the guide (legibility zone), during its travel and wait; the upper door 5a automatically locks, the optical scanning device advances along the guide driven by the actuator 7a until passing over the label it reads it, no matter what its angular position is; then it measures 8 its weight, it searches for the theoretical one 8 in the data base, using the label as a key and with the appropriate tolerance, it checks whether they are consistent: if so, it appropriately advises the customer to proceed with stowing the product, if not it requests to repeat the operation (invalid operation) after several attempts it gives an appropriate alarm - on each command this anonymous event is stored. For stowage, the customer presses the manual control 5al5 which causes the door 5a8 to open and the product to be ejected inside lb. The stowed products, thanks to the internal distributor, are laid down longitudinally (x axis); when a certain quantity of products is deemed to have been stowed; upon electrical horizontal command 3b5 the base retracts, and the products are unloaded onto the platform available below; with the command a sufficient lowering thereof is set, and the distributor is re-set. The process continues cyclically in this manner until the platform, having reached the base, thanks to its load, forces the opening of the cart base. It is also possible, with appropriate incentives (prize) and respecting one's anonymity, to reply to market research questionnaires (research menus) 6g2, or activate pastimes features 6g3 (pastimes menu); while shopping, from time to time the multimedia commercial message 14 is sent (audio, video, images or by other means) at asynchronous and strategic times (after a purchase of a competing or analogous product, or at other times). At the check-out counter, upon command or automatically, the collected shopping data are transmitted to the exchange/concentration system 22 cash register 22f, which immediately issues the receipt; if there are any products on the external compartments, they are counted in the classic manner whereupon the receipt is issued. This entails the elimination of check-out queues. After the cash register, the customer repeats the entry operation at a position of the storage station, to release the insertion unit. He/she then moves away outside, in the car park, with the cart filled with groceries. To remove the goods, it is sufficient to remove the closure and proceed normally. The movable platform, after removing the products, will automatically return to the base position (normal capacity) and this will allow normal telescoping parking. Conclusion The invention thus conceived can be subject to numerous modifications and variations, without thereby departing from the scope of the inventive concept.
