Abstract
Description
- The present application claims the benefit of U.S. Provisional Patent Application No. 60/675,849 filed Apr. 29, 2005, the entire contents of which is hereby incorporated by reference.
- The present invention is directed to an electronic handle for a wheeled cart, and more specifically, toward a shopping cart handle including an electronic module and display for providing a user with information while shopping.
- Shopping carts have remained essentially unchanged in form for many years. Recently, however, with the availability of inexpensive, compact computing power, attempts have been made to add small computers to shopping carts to assist users with shopping. For example, it is known to attach bar code readers to shopping carts to allow users to perform price checks and/or to perform a self-check out. One example of such a system is disclosed in U.S. Pat. No. 5,361,871 to Gupta, the contents of which are hereby incorporated by reference. However, the Gupta device appears likely to interfere with proper cart nesting and requires an electrical contact depending from the bottom of the cart for recharging which would likely be damaged in moving the cart through store aisles and/or over curbs in a store parking lot. It is not believed that systems such as the one disclosed in Gupta have been widely adopted.
- Related shopper-assisting devices that clip or otherwise detachably mount to a shopping cart handle are also known. However, these must be taken from a rack or other storage location by a user and attached to a cart handle before use. When a shopper reaches the check-out line, store personnel must detach the unit from the car and return the unit to a storage and/or charging station or rely on the customer to perform these actions. It is believed that these inconveniences have kept such devices from being widely adopted.
- It would therefore be desirable to provide an electronic shopper assisting device that is easy to use and maintain and that does not suffer from the aforementioned drawbacks.
- Various aspects and features of embodiments of the present invention will be better understood after a reading of the following detailed description together with the accompanying drawings wherein:

FIG. 1 illustrates acart handle 10 comprising first andsecond grips 12 extending from acentral housing 14.Central housing 14 includes adisplay 16, preferably a touch screen display, and a hollow interior for containing an electronic module or modules, abattery 15, illustrated inFIG. 17 , a circuit board, abar code reader 17, and other functional elements discussed herein.Housing 14 includes a first orfront portion 18 formed integrally withgrips 12 and arear portion 20 mounted tofront portion 18 either removably using fasteners such as screws or via a snap fit, or permanently using suitable adhesives, for example. Whenrear portion 20 is removably mounted, a suitable gasket is provided to ensure an watertight seal that will at the same time allow the unit to breathe and minimize condensation build up in the hollow interior ofhousing 14. -
Grips 12 include grippingportions 21 and joinhousing 14 at reinforcedportions 22 to increase the strength ofhandle 10 and to reduce the likelihood of damage where thegrips 12 joinhousing 14 when the handle is pushed or pulled or when downward pressure is placed on thehousing 14. Thegripping portions 21 have a circumference (or periphery if the grip portion does not have a circular cross section) of about 3 inches or 8 centimeters over most of their length to make them comfortable to grip for a user. Reinforcedportions 22 are flared and have a larger circumference or periphery which increases from the periphery of the grippingportion 21 to the sidewall ofhousing 14. As will be appreciated fromFIGS. 1 and 2 , the flared reinforcedportion 22 surrounds thegripping portions 21 ofgrips 12 on all sides so that a cross section of the grippingportion 21 projected towardhousing 14 will pass through without intersecting the largest circumference or periphery of reinforcedportions 22. - As illustrated in
FIG. 26 ,housing 14 may optionally include aratchet mechanism 29 to allow the angle ofhousing 14 and thus ofscreen 16 to be changed. Preferably, theratchet mechanism 29 allowshousing 14 to be pivoted untilscreen 16 faces a child seat in the cart so that, for example, videos could be displayed onscreen 16 to entertain children while shopping. The ratchet mechanism could be provided at any point along the length of grippingportions 21 ofgrips 12 or, with a somewhat modifiedhousing 14, not shown, at the interface ofgrips 12 andhousing 14 or insidehousing 14. -
Grip portions 12 are formed to have the greatest length required for a standard shopping cart and can be cut to shorter lengths for smaller carts. Thegripping portions 21 ofgrips 12 can have various cross sections such as the round cross section illustrated inFIG. 23 , the generally ovate cross section ofFIG. 24 and the kidney shaped cross section ofFIG. 25 . While grippingportions 21 are described herein as being integrally formed withfront portion 18 ofhousing 14, they can alternately be formed separately fromhousing 14 and connected thereto in a suitable manner. Alternately, for existing carts having handles that are not readily removable,housing 14 can be provided with suitable clamps or other fasteners to connecthousing 14 and the electronic modules contained therein to an existing shopping cart handle in a permanent or semi-permanent manner. - The housing and internal components are adapted to operate over a wide range of temperatures, −45° C. to 70° C., for example, so that the device can, for example, be stored outdoors in both extreme winter conditions and in direct sunlight in summer, and be resistant to both moisture and the impacts that are likely to be suffered by a shopping cart handle. The grips and housing are preferably formed from a suitable thermoplastic material.
-
Battery 15 is rechargeable and should be capable of operating the electronic modules for approximately 16 hours before recharging. -
Housing 14 includes anopening 24 for receiving a modularbar code reader 17 and an opening 28 providing access to an internal I/O port 30, illustrated inFIG. 8 , for example, which in the presently preferred embodiment comprises a USB port. Hardware contained withinhousing 14 will perform various functions and provide various displays onscreen 16 which functions and displays do not comprise a part of the present disclosure. - The hardware in
housing 14 may be activated by inserting an activation device intoport 30. In the present embodiment, the activation device comprises a solidstate storage device 32 having a USB interface compatible withport 30. Alternately, the electronic module could be activated usingbar code reader 17 to scan a bar code carried by an authorized user—on a customer loyalty card, for example. Whenstorage device 32 is used, information about a user ondevice 32 can optionally be made available to a processor inhousing 14 and/or transmitted to a central server in wireless communication withelectronic cart handle 10. -
Storage device 32 can be used to receive and store information from electronic cart handle 10 or a server in communication with the handle which information a user may later access using, for example, a home computer. Where privacy is an issue,device 32 may merely contain a serial number to identify thedevice 32 to a secure server in communication with the electronic module. In such cases, no personal information would be stored ondevice 32. This would substantially prevent the disclosure of private information if adevice 32 is lost. For purposes of the present disclosure, it is merely necessary to know that an authorized user can be identified to a processor inhousing 14 with eitherdevice 32 or a bar code on a customer loyalty card, and that a processor in the electronic module, which may for example be in wireless communication with a server and/or the internet, can provide information to the user of the electronic cart handle 10 based on previously stored preferences. -
Memory device 32 is illustrated inFIG. 4 and includes abody portion 34 in which a suitable compact flash or other solid-state memory is contained, aUSB connector 36 insertable intodrive 30, acap 38 and aring 40 or similar arrangement to allowdevice 32 to be connected to a key ring. - An
alternate memory device 42 is illustrated inFIG. 5 .Memory device 42, in addition to abody portion 44 holding solid state memory, aUSB connector 46, acap 48 and aring 50, includes akey member 52 having a predetermined shape, which is a cross in the present embodiment. The shape ofkey member 52 matches the shape of akey opening 54, illustrated inFIG. 7 , in a housingadjacent port 30.Key member 52 fits intokey opening 54 whenmemory device 42 is used.Key member 52 projects further frombody 44 thanconnector 46 and thus enterskey opening 54 and actuates arelease mechanism 56 which unlocksdoors 58 overport 30. This arrangement makes it less likely that foreign objects will be inserted intodrive 30 and makes it more difficult for a user to use an unauthorized device inUSB port 30.Key 52 may be retractable, with athumb slide 53, for example, to make USB drive 30 usable with standard USB ports, such as the ports found on a user's home computer. - In addition to activating electronic modules in
housing 14, the insertion ofmemory device FIGS. 9-12 , thecart 59 to whichelectronic handle 10 is attached may include a wheel locking arrangement for securing thewheels 60 of shopping carts. These wheel locking devices may comprise asolenoid 62 for selectively driving arod 64 into an opening inwheel 60 to substantially preventwheel 60 from turning.Solenoid 62 is controlled by signals from the processor inhousing 14 and only unlockswheels 60 when an authorizedmemory device port 30. -
FIG. 12 illustrates a plurality of nestedshopping carts 70 equipped withelectronic handles 10. The size and position ofhousing 14 substantially prevents thehandles 10 from interfering with cart nesting when mounted on a variety of standard carts. In addition, electronic cart handle 10 is preferably mounted so thatdisplay 16 makes an angle of about 30 degrees with respect to the horizontal to improve visibility and minimize glare, while not interfering with the use of a child seat in the cart or with cart nesting. -
FIG. 13 illustrates a daisy chain arrangement for rechargingbatteries 15 contained withinhousing 14 of a plurality of nestedcarts housing 14 includes apower cord 86, apower outlet 88 and apower LED 90 which lights when power is being supplied to the cart on whichLED 90 is mounted. Thepower cord 86 onfirst cart 80 is attached to a suitable DC power source 92 (such as a transformer connected to an AC power source), thepower cord 86 ofsecond cart 82 plugs intopower outlet 88 of thefirst cart 80, and thepower cord 86 ofthird cart 84 plugs intopower outlet 88 ofsecond cart 82. LED's 90 on each cart turn on when that cart is connected to a source of electric power. In this manner, it can readily be determined whether all carts in a nested series are being recharged. This arrangement is best suited for a last-in first-out arrangement of carts and therefore is primarily intended for situations wherein groups of carts are connected and fully charged, overnight, for example, before being used by purchasers. In an alternate arrangement, each of the plurality of nested carts could be plugged individually into a power source until fully charged. This would allow for the carts that have been charging the longest to be removed from a series of carts first, over the course of a business day. -
FIG. 14 illustrates acart corral 100 having first andsecond rails 102 each of which is provided with an electrically conductive chargingrail 104, best seen inFIG. 17 , connected to apower source 103.Corral 100 includes first and secondangled guide members 106 for guiding a cart into the corral.Electrical contacts 108 on the ends ofgrip portions 12 make electrical contact with these charging rails to recharge abattery 15 insidehousing 14. Thecontacts 108 may alternately be formed inseparate end caps 107 which can be attached to thegrip portions 12 aftergrip portions 12 are cut to a proper length. Eithercontacts 108 or chargingrails 104 may be flexible or displaceable to ensure a good electrical connection betweencontacts 108 and chargingrail 104 even when the separation betweenrails 102 and or the separation between the ends ofhandle 10 is not constant. Alternately,end caps 107 can be telescopically mounted withinhandle grip portions 12 and spring biased away from one another to accommodate variations in the separation between the charging rails.Corral 100 may further includes hingedflaps 112 or similar structures to ensure that carts pass through the corral in a single direction and that the cart that has been charging for the longest period time is removed first to provide for first in first out recharging. -
FIG. 18 illustrates a charging system integrated into a daisy chain cart security system. In such a security system, nested carts are secured by inserting amember 114 chained to one cart into aslot 116 on an adjacent cart. Themember 114 may be released by inserting a coin or token to release a single cart. The coin or token is returned when the cart is returned to the nested line of carts after use. An example of such a daisy chain locking system (which does not include the electrical charging system of the present invention) is illustrated in U.S. Pat. No. 4,474,282 to Lenader, the contents of which are hereby incorporated by reference. - As illustrated in
FIGS. 19 and 20 ,member 114 includes ahasp 115 that connects to a locking mechanism inslot 116 andelectrical contacts 118 that engageelectrical contacts 120 inslot 116 to electrically connect two carts.Electrical contacts 120 inslot 116 are in turn connected bywire 121 to theelectrical contacts 118 of a member chained to that cart which can be inserted into aslot 116 of an adjacent cart in a similar manner to electrically connect and mutually secure a plurality of nested carts in series. -
FIG. 21 illustrates a recharging system that comprises asingle rail 130, mounted, for example on awall 132.Rail 130 includes achannel 133 in which a pair of spacedelectrical contacts 134 are mounted, one above the other for making electrical contact with a pair of vertically projectingelectrical contacts 136 on the end of acart handle 138. Aguide channel 140 is provided on the groundadjacent rail 130 to help guide the cart wheels and properly position cart handle 138 with respect torail 130. This arrangement is space-efficient and allows for the recharging of a battery through a single end of a cart handle. - The present invention has been described herein in terms of several preferred embodiments. Obvious additions and modifications will become apparent to those skilled in the relevant arts upon a reading of the foregoing description. It is intended that all such obvious modifications and additions be included within the scope of this invention.
