Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention relates generally to a shopping cart and, more particularly, to a modified shopping cart which automatically returns to a desired location when not in use.
  • 2. Description of the Prior Art
  • The use of shopping carts in retail shopping is well known. Shoppers at grocery stores or other retail outlets often utilize such carts to gather their items in the retail outlet and also to carry their purchased items to a vehicle when they depart. A problem which is created by such customary use of shopping carts is that once carts are used, the shoppers often leave carts where they last used them, which is typically scattered all over a parking lot. Consequently, the retail outlet must typically employ workers specifically to round up and return carts to a desired location (or have workers stop performing other tasks to do the same) so they may be easily accessed by future shoppers.
  • Thus, there remains a need for a shopping cart which would eliminate the need for retail workers to manually round up shopping carts after use and return them to a desired location. It would be helpful if such an automated return shopping cart was motorized to enable it to propel itself when required. It would be additionally desirable for such an automated return shopping cart employed global positioning system (“GPS”) components and sensors to enable shopping carts to navigate themselves to a predetermined, desired location while avoiding pedestrians and vehicles.
  • The Applicant's invention described herein provides for a motorized shopping car adapted to automatically propel itself to a predetermined, desired location at a retail outlet when not in use by a shopper. The primary components of Applicant's automated return shopping cart are a base cart modified to include a power source, a GPS system, sensors for detecting objects, sensor for detecting use activity, and a programmable logic controller. When in operation, the automated return shopping cart automatically recognizes when it is no longer in use and returns itself to a desired location to wait to be used again. As a result, many of the limitations imposed by cart corralling procedures of the prior art are removed.
    • SUMMARY OF THE INVENTION
  • An automated return shopping cart for enabling a shopping cart to sense when it is not in use and automatically return itself to a cart corral area when it is not in use. The automated return shopping cart comprises a conventional shopping cart modified to include an automation component, a GPS component, object sensors, activity sensors, two docking ports, a touchscreen, and a WiFi component. The automation component, which includes the programmable logic controller, a rechargeable battery, the powertrain components, and brakes, is wired to the GPS component, object sensors, activity sensors, docking ports, touchscreen, and WiFi component, enabling the provision and receipt of electrical power with the battery and electrical signals with said components. When in use, the automated return shopping cart operates in substantially the same manner as a conventional shopping cart, except it additionally allows for the display of advertisements or for users of the automated return shopping cart to access content, including without limitation websites or movies, from the Internet.
  • Whenever the activity sensors sense that the cart is not in use, the automation component causes the cart to be moved back to a desired location, typically the cart corral area. While being propelled to the cart corral area, the GPS component determines the route based on the location of the desired destination. While in route to the desired destination, object sensors are used to detect objects in the current and potential path of the cart. When objects are detected, an alternate route which avoids the objects is calculated and employed.
  • Once the cart makes it back to the cart corral area it is docked with its docking components to allow the battery to recharge. Thus, when a shopper takes the cart seeking to utilize it, electrical power has been stored to power the subsequent operation of the cart.
  • It is an object of this invention to provide a shopping cart which would eliminate the need for retail workers to manually round up shopping carts after use and return them to a desired location.
  • It is another object of this invention to provide an automated return shopping cart motorized to enable it to propel itself when required.
  • It is yet another object of this invention to provide an automated return shopping cart employing GPS components and sensors to enable shopping carts to navigate themselves to a predetermined, desired location while avoiding pedestrians and vehicles.
  • These and other objects will be apparent to one of skill in the art.
