Abstract
An accessory tray is connected to, or extends integrally from, a shopping cart handle and extends a limited distance forward from the handle. The tray extends forward above, but not significantly interfering with, the child-seat area of the cart. Preferably, the forward extremity is not directly connected or attached to the cart, but rather the tray is cantilevered from its rear end/edge fixed to/at the handle and extends otherwise unconnected forward from the handle. A forward tray portion may rest on, or be close to, an upper portion/end of the cart rear wall. The preferred tray is substantially planar, featuring a single, flat platform with an upending rim, wherein no part extends above said top level of the handle. The tray remains in place for nesting of multiple carts, and is received in a space between nested portions of the cart to which it is connected.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
(19) Referring to the Figures, there is shown one, but not the only, embodiment of the invented accessory tray for use with a shopping cart.
(20)
(21)
(22) The connector portion 30 comprises an upwardly facing semi-cylindrical surface 32 that extends along the entire, or substantially the entire, width from right to left end of the tray 10. This surface 32 is made to have the generally the same, or the same, diameter as a conventional shopping cart handle 110 outer surface. This way, the connection portion 30 can be raised up to the bottom of the cart handle and adhesively attached to said bottom and preferably also to portions of the front and rear of the handle. For example, if the connector portion 30 forms a half-cylinder by extending 180 degrees, the surface 32 will contact and be adhesively connected to 180 degrees of the circumference of the handle. A different amount of curvature may be used, for example, less than 180 degrees or more than 180 degrees, but 170-190 degrees is preferred. In the case of greater than 180 degrees, the connector portion 30 may require snapping onto the handle, for example. It is preferred that no part of the tray but the rear connection portion, generally forming or disposed at the rear edge of the tray, will be fixed or directly connected to the cart; other portions, such as the bottom surface 16 and the front rim 18 may contact the cart but they are preferably not fixed or directly connected to the cart.
(23) It may be noted from
(24) The plane P3 of platform top surface 14 is preferably parallel to the top plane P1 of the platform portion 12 and also preferably parallel to the bottom plane P2 of the platform portion 12. Bottom plane P2 and plane P3 are only a small distance apart so that the thickness of the platform portion excluding the rim 18 is, for example, preferably less than inch, more preferably less than inch, and most preferably about inch.
(25) The top edges 34 of the connector portion 30 reach up higher than the rim 18 of the platform portion 12, and reach to, and define, a plane P4 that is preferably parallel to planes P1, P2, and P3. Note that
(26)
(27) The tray 10 is preferably molded from polymer, but it may alternatively be made from other durable and preferably weather-resistant material(s). The tray 10 may be solid, but, alternatively may have hollow portions. Preferably, the tray is a single piece, and has no hinge, no moving parts, and no disconnectable portions.
(28)
(29) From the fixed connection to the handle, the platform portion 12 extends forward over the space between the handle and the upper end 114 of the rear wall 115, which space may be called a handle space SH. The platform portion 12 extends to, or slightly forward beyond, the upper end 114 of the rear wall 115 of the cart 100, so that the front side or front extremity of the tray/platform may be described as being generally over the upper portion/end of the rear wall. Generally over the upper portion/end of the rear wall may include extending forward of upper end 114 only 2 inches or less, and more preferably 1 inch or less. Preferably, the platform portion does not extend over the child-seat seat flap, or at least not significantly over the child-seat seat flap. Further, in the in-use configuration of the shopping cart, portrayed in
(30) Said upper end 114 typically comprises a first horizontal bar 116, one or more vertical bar 117 top ends (or loop ends) 118 that loop around horizontal bar 116, a second horizontal bar 120, and secondary vertical bars having top ends (or loop ends) 122 that loop around second horizontal bar 120. Typically, first horizontal bar 116 is higher than second horizontal bar 120 and loop ends 122, and loop ends 118 are spaced far to the right and left, so that the bottom surface 16 rests only on horizontal bar 116. In this condition, some of the weight of the tray and its contents may be supported by said horizontal bar 116. When the bottom surface 16 contacts said bar 116, said contact is not fixing or attachment of the tray to said bar 116, but rather simply resting on the bar 116. Said resting on the bar 116 preferably comprises only a small amount of weight/force so that the bar 116 and upper end 114 still may be moved relative to the tray without harming the tray or the connection of the tray to the handle, and without disrupting/changing the position of the tray. For example, when the rear wall 115 of the cart pivots/folds for nesting with other carts, said upper end 114 will rotate relative to the tray without significant interference and without disrupting the tray position or connection to the handle.
(31) Alternatively, in the in-use position, the bottom surface 16 may be slightly spaced from said bar 116 and from the other portions of upper end 114 of the rear wall 115. In this condition, the connection portion 30 being fixed to the handle will be the only support mechanism for the tray and its contents.
(32)
(33) To enter the nesting configuration, the child-seat seat flap 123 and child-seat back 124 (see
(34) In the nest configuration, a front portion of the tray, specifically about the front - of the platform portion 12, is received between the upper end 114 of the rear wall 115 and the upper end of the child-seat back 124. To enter this position, the tray 10 has not moved relative to the handle 110, for example, it has not pivoted or slid relative to the handle 110 as it remains fixed to the handle. The rear wall 115 and the child-seat back 124 have moved relative to the each other and relative to the tray 10. Specifically, the rear wall has pivoted, typically on horizontal bar 116, so its upper end 114 is generally horizontal underneath the tray platform portion 12. Typically, this occurs by the vertical bars 136 pivoting on the horizontal bar 116, and the tray remains resting (or slightly spaced from, in certain embodiments) on the horizontal bar 116 and still extending across the handle space SH (see
(35) The position of the tray 10 in the nesting configuration is best shown by the cross-sectional view in
(36) The preferred tray 10 is connected to the central portion of the handle, for example, only about the middle half of the handle length, with about of the handle length extending to the right and about of the handle length extending to the left out beyond the tray. This arrangement centers the tray 10 on the handle and centers the tray relative to the vertical longitudinal centerplane of the cart, which leaves the right and left portions of the handle uncovered and exposed, for grasping to drive/manipulate the cart. Except for the very small amount of the connection portion that may extend along the rear side of the handle, the tray preferably does not extend rearward of the handle 110 in the in-use or in the nesting configuration; the preferred tray may be described as extending less than 1 inch, more preferably less than inch, and most preferably less than inch, rearward from the handle at all times.
(37) As discussed above, the preferred tray is connected to and contacts only approximately the bottom half of the handle, for example the bottom 90-200 degrees, more preferably the bottom 135-200 degrees, or most preferably the bottom 135-180 degrees of the circumference of the handle, rather than the top half of the handle circumference. This results in the low-profile that is effective for holding the personal items without interference with the other functions of the cart. Alternatively, the tray may be fixedly connected to the top side and/or front or rear side of the handle, with the platform portion 12 still extending forward in such a way that it will be in space SN when the cart is in the nesting configuration. Examples of such a top-side connection are given in Provisional Application Ser. No. 62/165,036, and so are incorporated herein.
(38) While the currently-preferred connection method is glue/adhesive, other fastening methods and means may be used in certain embodiments. For example, adhesive may be supplemented or replaced by ties, straps, screws, nuts and bolts, clips, pins, and/or other fasteners, in certain embodiments.
(39)
(40) Apertures 40 are one example of apertures extending all the way through the platform portion 12, from top to bottom, that may serve as drain holes for rain or other liquid that lands on the platform portion 12. The draining function may be in addition to, or instead of, the apertures receiving ties or other fasteners. The preferred number of drain holes is 3-8, with the lower end of this range being preferred so that the platform portion strength and durability is not compromised. The preferred location of apertures 40 is along the rear of the top surface 14, as shown in
(41) Certain embodiments of the tray are integrally formed with the shopping cart, for example, integrally fixed to the handle during original manufacture of the cart. Certain embodiments may be integrally formed together with a handle grip and/or sleeve that is screwed onto, or otherwise fastened to the handle, for example, as understandable from handle grip G and fasteners F called-out in
(42) While one style of shopping cart, and one style of cart handle, are portrayed in the Figures, it may be understood that alternative styles of carts and cart handles may cooperate with the preferred tray in certain embodiments. For example, the tray may be connected to, or extend integrally from, various cart handles, for example, those that are a single cylindrical bar rather than the more complex handle having the added handle grip G and fasteners F shown in the Figures. It will also be understood that the conventional shopping cart handle is the bar or other structure that is at or near the top rear of the cart, and is the structure that the user typically grasps for driving and maneuvering the cart while shopping.
Summary of Certain Embodiments
(43) Certain embodiments of the tray may be described as: A tray for a shopping cart with a handle having an underside, the tray comprising, consisting essentially of, or consisting of: a connection portion; and a substantially planar platform portion having a rear side connected to the connection portion, the planar platform extending forward from the connection portion and having front, left, and right side, a planar top surface for receiving items placed by a user, and a rim upending around the planar top surface on the front, left and right sides; wherein the connection portion has a length parallel to the handle, and has a semi-cylindrical surface extending along all or substantially all of said length, for being fixed to the underside of the handle. Substantially all of said length may be along 51-99 percent, or more preferably 60-99 percent, or most preferably 80-99 percent of the length, because greater surface area and length of the fixed connection will translate to a greater secure and durable connection and greater immovability of the tray. Such a tray preferably features the planar top surface being substantially or entirely continuous and flat and/or with no recesses and no upending compartment walls that divide the planar top surface into compartments. The semi-cylindrical surface of the connection portion may extend circumferentially 90-200 degrees, or 170-190 degrees, for example.
(44) Certain embodiments of the invention may be described as: a combination of a shopping cart and an accessory tray on the shopping cart, the shopping cart comprising a handle at an upper rear end of the cart, a rear wall having an upper end that is forward of the handle and an opposing lower portion, wherein there is a handle space between the handle and the rear wall upper end and a child-seat portion having a seat flap and a child-seat back with an upper end, wherein, in an in-use configuration for the cart, the rear wall is generally vertical and the seat flap is generally horizontal and the child-seat back is generally vertical forward of the seat flap; the tray comprising, consisting essentially of, or consisting of: a connection portion fixed to the handle of the shopping cart; and a substantially planar platform portion having a rear side connected to the connection portion, a front side, a left side, and a right side, a planar top surface for receiving items placed by a user, and optionally but preferably a rim upending around the planar top surface on multiple of the front, left and right sides; wherein the platform portion extends forward from the connection portion across said handle space to place the front side of the platform portion generally over the upper end of the rear wall so that said tray does not extend over said seat flap; and wherein, in a nesting configuration of the cart, the rear wall pivots to move the rear wall lower portion forward, and the child-seat back pivots rearward so that said rear wall and the back are generally parallel and generally horizontal and there is a storage space between the upper end of the rear wall and the upper end of the child-seat back, the front side of the tray platform portion being received in said storage space. The tray of such a combination preferably does not move relative to the handle when the shopping cart moves from the in-use configuration to the nesting configuration. The connection portion has a length parallel to the handle, and may have a semi-cylindrical surface extending along all or substantially all of said length, for being fixed to an underside of the handle. The planar top surface may be continuous and flat, with optional small drain apertures, and/or have recesses in the planar top surface and no upending compartment walls that divide the planar top surface into compartments. The connection portion has a length parallel to the handle, and may have a semi-cylindrical surface extending along all or substantially all of said length, for being fixed to an underside of the handle, and wherein said semi-cylindrical surface extends circumferentially 90-200 degrees, or circumferentially 170-190 degrees, for example. In such a combination, the tray platform portion may rests on said upper end of the rear wall, for example, when the cart is in the in-use configuration and also when the cart is in the nesting configuration. It is preferred that the tray be immovable relative to the handle, but certain embodiments may have slight flexibility, with resilience, especially or only in the platform portion. The handle of the shopping cart may be generally cylindrical and have a bottom half and a top half, wherein the tray does not contact said top half, and/or wherein the tray does not extend above said top half, and/or wherein the tray does not extend above a horizontal plane that passes through said handle top extremity. The tray may be fixed to the bottom half of the handle, and the platform portion may extend forward from the bottom half of the handle.
(45) Certain embodiments are methods of installing a tray as described herein on a shopping cart, and using the shopping cart and/or transforming the shopping cart between the in-use configuration and the nesting configuration, wherein the tray stays in place, preferably un-moved relative to the handle of the cart, in both configurations. This is possible because the size, shape and design of the tray and its connection or integral-fixing is such that the tray is not in the way of moving parts and is not forced to move or forced loose by said nesting. The tray fits between the nested components of the cart, specifically, the pivoting rear wall and the pivoting child-seat components that move relative to each other for said nesting. This allows a manufacturer, grocery, or other business to install the trays, or order carts with the trays, a single time and they will typically remain in place trouble-free for long use of both the cart and the tray. Customers will enjoy the convenience of the simple, minimal-parts, slim/thin profile tray installed in a low-profile orientation on the cart. Customers will enjoy the convenience, safety, and the small footprint of the tray, while being able to rest their important and/or shopping-related personal items on the tray for easy access through the shopping experience.
(46) Although this invention has been described above with reference to particular means, materials and embodiments, it is to be understood that the invention is not limited to these disclosed particulars, but extends instead to all equivalents within the scope of the following claims.
