FIELD OF THE INVENTION
The present invention relates to systems and methods for loading and unloading goods into a shopping cart. More particularly, the present invention relates to a structurally improved shopping cart and associated methods.
BACKGROUND
The traditional metal, plastic, and plastic-hybrid framed shopping cart is used by millions of people worldwide to accumulate their goods while shopping as well as to unload their goods into their vehicle. Loading goods into the shopping cart requires the consumer to hoist them over top of the side panel of the cart and drop the goods into the cart bin. For heavier items, the traditional shopping cart requires the consumer to bend over and place them on the rack under the cart.
Unloading the goods is equally burdensome requiring the user to bend over the side panels, reach into the cart, and hoist the goods out from overtop of the panels. Loading and unloading heavy items such as milk gallons and large packs of water into the shopping cart becomes problematic for a large segment of the public.
There exists a need in the art for an improved shopping cart and associated methods.
This background is provided to reveal information believed by the applicant to be of possible relevance to the present invention. No admission is made as to prior art and nothing within the background should be construed as prior art against the present invention.

Referring to Fla 1A, an improved shopping cart, hereinafter the cart 100, will be described in more detail. The cart 100 may include a bottom bed panel 135 perpendicular to, and surrounded by a first side panel 101, a second side panel 102, a front panel 104 and an end panel 103. A cart handle 108 may extend distally from an end portion of the cart 100 proximate the end panel 103.
In one embodiment the cart 100 may include a rotational front panel 104 that may rotate along at least one of the front panel's 104 frame axes utilizing a plurality of rotation facilitating members 106. In this embodiment, the rotation facilitating members 106 may be a plurality of closed loops 106a that encircle both a lower frame axis of the front panel 104 and a portion of the frame of the inside bed panel 135 proximate thereto.
The front panel 104 may be removably attached to the cart bed top 136 via a plurality of fastening members 105. In this embodiment, the fastening members 105 may be a plurality of upper block magnets 105a fixedly attached to the first side panel 101 and the second side panel 102 respectively. The magnets may be of Neodymium, Alnico, Ceramic or Cobalt and in some embodiments may include a coating made of plastic, zinc, or the like. The cart front panel 104 may be magnetically and removably attached via the attraction between the metal frame of the front panel 104 and the upper block magnets 105a. Therefore, the cart 100 may transition from a closed position as depicted in FIG. 1A to an open position such as the one depicted in FIG. 1B when the front panel 104 is removed from the cart bed top 136 and is swung down via the closed loops 106a to an arced range of 180 degrees or more below the cart bed bottom 137. In this embodiment, the first side panel 101, the second side panel 102, and end panel 103 may be fixed in non-rotatable positions. As will be shown and described in FIGS. 6A and 6E hereinafter, types of magnets that may be used with the improved cart 100 may vary depending on need, preference and circumstance. These magnets may include semicylindrical magnets 623 with a bar attachment channel and channel, cylinder, or block magnets 624 with a bar attachment channel 625. These magnets 623, 624 may be structured to easily fit on the bars of a cart 100. Therefore, these magnets may be used to easily convert a traditional shopping cart to an improved cart 100.
FIG. 1B shows the cart 100 in the open position with the front panel 104 removed from the fastening members 105 and hanging below the cart bed bottom 137 by the closed loops 106a. The rotational direction 107 of the front panel 104 is shown indicating the front panel 104 may include an arced swing pattern distal to the cart 100 when transitioning from an open to closed position.
FIG. 1C illustrates another embodiment of the invention whereby the rotation facilitating member 106 may be a coil 106b. The coil 106b may be made of any number of durable and malleable material that may wrap around a lower frame axis of the front panel 104 and a portion of the frame of the inside bed panel 135 proximate thereto. The coil 106b material may be at least one of spiraled metal, plastic, metal coated with plastic, fiber, hybrid thereof, and the like.
In this embodiment, the cart 100 may transition from a dosed position as depicted in FIG. 1A to an open position. This may happen when the front panel 104 is removed from upper block magnets 105a on the ends of the first and second side panels 101, 102 at the cart bed top 136 and is swung along the indicated rotational direction 107 via the coil 106b. This may be an arced range of 180 degrees or more below the cart bed bottom 137. In this embodiment, the first side panel 101, the second side panel 102, and end panel 103 may be fixed in non-rotatable positions.

Furthermore, the bar attachment tunnel 604 may be structured to accommodate the geometric configuration of the cart segment it is to be attached. Like the cylinder magnet 601, in some embodiments this may simply be a curved interior tunnel to secure the magnet to a shopping cart bar. In other embodiments, the curved interior tunnel may be supplemented with a perpendicularly oriented tunnel to accommodate the crisscrossed bar structure of cart panels. Furthermore, the block magnet 604 may be polygonal with a plurality of flat faces 630 structured to facilitate the engagement of a cart panel thereon.
Fla 6B illustrates an improved front panel 605 that may be associated with an improved cart 100. In this embodiment, the front panel 605 may include a pair of attachment loops 607 at opposing upper corners of the front panel 605. The attachment loops 607 may be circular extensions of the upper edge of the front panel 605 structured to accommodate the horizontally oriented upper edge of the side panels 101, 102. With this improved front panel 605, the existing front panel 104 of the cart 100 can be removed and this improved front panel 605 can be fitted onto the extended upper edge bars that would protrude from the respective end of the cart 100. These attachment loops 607 may act as the upper fastening members 105 in lieu of other fastening members 105 mentioned herein.
Additionally, the improved front panel 104 may include a pair of handle loops 606 at opposing upper corners of the front panel 605 just outside the attachment loops 607. In some embodiments, the handle loops 606 may be circular extensions of the upper edge of the front panel 605 continued from the attachment loops 607. In other embodiments, the handle loops 606 may be separate members soldered or attached by other means to the front panel 104. In any embodiment, the handle loops 606 may be used as a facilitating means to grab and pull the front panel 104 from the top of the cart 100 and rotate it downward to an open position.
FIG. 6C illustrates the clamp 609 that may be used with the improved cart 100. Like the magnets 601, 602, the clamp 609 may be bifurcated into a first segment 611 and a second segment 612 separated by an attachment channel 615 to facilitate the clamp 609 being attachable to a cart 100 that has been constructed before improvement. Furthermore, the attachment channel 615 may be structured to accommodate the geometric configuration of the cart segment it is to be attached. Like the magnets 601, 602 in some embodiments this may simply be a curved interior tunnel to secure the clamp 609 to a shopping cart bar. In other embodiments, the attachment channel 615 may be supplemented with a perpendicularly oriented tunnel to accommodate the crisscrossed bar structure of cart panels. In any embodiment, the front face 616 of the clamp 609 may be structured to accommodate a vertically oriented front panel bar to removably secure the front panel 104 to the cart 100.
FIG. 6D shows a receiving hook 617 that may be used with the improved cart 100. Similar to the clamp 609, the receiving hook 617 may be structured to accommodate a vertically oriented front panel bar to removably secure the front panel 104 to the cart 100. The receiving hook 617 may include a closed attachment end 618, which may be a circular end structured to accommodate a vertically oriented side panel and fixedly attach the receiving hook 617 thereto. The opposing end of the receiving hook 617 may be a curved open end 619 structured to receive and removably secure an front panel 104 to a side panel 101, 102. An elongate flexible medial member 620 may be bendable. This may allow the receiving hook 617 to stretch to expose the curved open end to allow an front panel 104 to be ensnared by the panel receiving area 622 or allow for the receiving hook 617 to release the front panel 104. In any embodiment, the receiving hook 617 may be structured to accommodate a vertically oriented front panel bar to removably secure the front panel 104 to the cart 100.
FIG. 6E illustrates different types of magnets that may be used with the improved cart 100. These magnets may include semicylindrical magnets 623 with a bar attachment channel and a semi-block magnet 624 with a bar attachment channel 625. These magnets 623, 624 may be structured to easily fit on the bars of a cart 100. Therefore, these magnets may be used to easily convert a traditional shopping cart to an improved cart 100.
FIG. 7 shows an improvement kit 700 that may be used to convert a traditional cart into an improved cart 100. An improvement kit 700 may come with all or some of the listed components as well as other components listed within this application.
