Embodiments of the invention are directed to a shopping cart. In one embodiment, a shopping cart includes a base, a pair of masts, and a basket. The base extends generally horizontally between a front portion and a rear portion of the cart and including a plurality of wheels. The pair of masts extends generally vertically upward from the base in a generally singular plane extending laterally across the rear portion of the cart. Each mast includes a rear portion facing the rear portion of the cart and defining a generally straight surface, and a front portion facing in a direction generally opposite the rear portion of the respective mast and defining a generally concave curved portion. The basket includes a front portion and a rear portion with the rear portion of the basket connected to the base via the pair of masts to support the front portion of the basket in a vertically spaced relationship over the base adjacent the front portion of the cart.
In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front, ” “back,” “leading,” “trailing,” etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments of the present invention can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
In one embodiment, slots 91A, 91B have a length that is substantially equal to a length of panel 110A, 110B, respectively, as extending longitudinally between a front portion 50 and rear portion 51 of cart 10. In one embodiment, slot 93 has a length that is substantially equal to a length of panel 112 extending transversely across a front portion 50 of cart 10
Grasping zone 90 enables a consumer to conveniently grab any portion of cart 10, from the side, the front, or the rear of the cart to pull or push the cart in a desired direction. In this respect, shopping cart 10 provides an ergonomic shopping experience by enabling the consumer a grab-and-go interface with cart 10 in which the consumer can readily grab handle 12 from any position (front, back, side, rear) relative to the cart 10, and go in a desired direction by pushing, pulling or turning the cart as desired. In one example, this panoramic grasping mechanism enhances a consumer's ability to place items in basket 14 by enabling the consumer to stand near a front portion 50 of cart 10 while putting items in basket 14 and pulling cart 10 via front portion 66 of frame 60 of handle 12.
As shown in FIGS. 1-2, structural frame 100 of basket 14 defines a size and shape for basket 100, and enables support of a plurality of panels 11A, 110B, 112 between respective frame members 102A-108 of structural frame 100 of basket 14. In one aspect, panels 11A, 110B, 112 are identified in FIGS. 1-3 by dashed lines forming a generally trapezoidal or generally rectangular shape, although panels 110A, 110B, 112 are not strictly limited to these shapes.
In one embodiment, side panel 10A extends upwardly from and is supported by bottom side frame member 106A while extending longitudinally between rear upright frame member 102A and front upright frame member 104A. Side panel 110B extends upwardly from and is supported by bottom side frame member 106B while extending longitudinally between rear upright frame member 102B and front upright frame member 104B. Side panel 110A and side panel 110B are generally parallel to each other, and spaced from each other. In one aspect, side panel 110A and side panel 110B are oriented in an angled pattern of convergence toward a front portion 50 of cart 10 so that front portion 50 of cart is narrower than rear portion 51 of cart 10. Front panel 112 extends upwardly from and is supported by bottom front frame member 108 while extending transversely across front portion 50 of cart 10 between front upright frame members 104A and 104B. In one aspect, front panel 112 is positioned generally perpendicular to side panels 110A, 110B, as well as generally perpendicular to bottom panel 114. As shown in FIG. 3, bottom panel 114 extends between, and is supported by, bottom side frame member 106A, bottom side frame member 106B, and bottom front frame member 108.
Accordingly, with side panels 110A and 110B, front panel 112, and bottom panel 114 supported by structural frame 100 (including frame 60 of handle 12), basket 14 defines a robust container suitable for carrying items in basket 14
Moreover, in one embodiment, the strength and stability provided by structural frame 100 of basket 14 (including frame 60 of handle 12 acting as upper portion 101 of frame 100) enable panels 110A, 110B, 112 of basket 14 to have a thin wall construction. In one aspect, because handle 12 acts as upper portion 101 of structural frame 100 of basket 14, upper edges 86A, 86B, 85 of respective side panels 110A, 110B, 112 of basket 14 are sized to terminate in a low-profile thickness. This arrangement avoids bulky plastic or metal reinforcers at mouth 73 of the basket 14, which simplifies basket 14 while contributing a smoother, ergonomic basket 14 having a sleek appearance and gentle tactile feel. In another aspect, the strength of frame 100 of basket 14 enables avoiding the use of additional support members extending transversely (whether diagonal or horizontal or vertical) across a middle portion of panels 110A, 110B, 112.
In another aspect, side portions 65, 64 of handle frame 60 extend in substantially the same generally vertical plane as respective side panels 11A, 110B, and front portion 66 of handle frame 60 extends in substantially the same generally vertical plane as front panel 112. This arrangement positions handle 12 directly over the respective panels of basket 14 to provide direct support to these panels 110A, 110B, 112.
As shown in FIGS. 1-7, basket 14 including frame members 102A-108 and panels 10A, 110B, 112, comprises a generally continuously smooth surface, that is generally free of sharp protrusions, edges, ribs, etc, so as to be comfortable for contact with a body of a consumer. In one aspect, as shown throughout FIGS. 1-8, each side panel 110A, 110B, and front panel 112 (also an upper surface of bottom panel 114) comprise a generally contiguous member 111 forming a pattern of holes 113. In one aspect, holes 113 are round, while in other aspects, one or more holes have other shapes, instead of round holes, such as squares, diamond, triangular, elliptical, etc.
