Adjustable tray assembly

Abstract

An adjustable tray assembly is configured to span a distance between the handle of a shopping cart to the backrest of the seat area. The assembly is adjustable to different sizes of shopping carts by utilizing an attachment member within a tray portion at the handle that can be located in different positions, and by permitting the pivoting of an arm portion of the assembly. The pivoting nature of the arm portion allows the arm portion to adjust to the different depth of the seat areas and type of cart. A latch is used to secure the arm portion to the backrest of the seat area. A hollowed area is formed in the arm portion for a child to use the seat area.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present application relates to a tray assembly, and more particularly to an adjustable tray assembly for coupling to a shopping cart to help restrain children.

2. Description of Related Art

Shopping carts are prevalent within society and are used in most mainstream stores for carrying goods both prior to payment and after payment. Most shopping carts are designed to allow for a child to sit at the front of the cart next to the handle used to push the shopping cart. The child is set to face the user. Each shopping cart typically has a back rest, seat and front handle area. As children can be various sizes, the space in the seat is plentiful, thereby allowing children in the seats to move and escape. This can be dangerous for children. Approximately 24,000 children are injured in shopping cart accidents every year: fractured skulls, concussions, and sometimes even death.

Despite the good intentions of users and the store owners, often the carts are dysfunctional, allowing for proper securing of a child impossible. Straps meant to secure the child are often broken, torn, or not able to adjust around the child, thus leaving him/her unsecured and free to move around as he/she pleases. However, even when buckled in properly, certain kids are prone to escaping or unlatching themselves. Regardless of the situation, this creates a very stressful shopping experience for the parent and a safety concern for the child.

Some devices have been developed to attempt to cure these issues, however, they are all deficient. Some of the main concerns is that the devices are not compatible with a majority of shopping carts. Shopping carts can vary in material and size between stores. Additionally, the devices fail to adequately secure the child as they generally don't surround the child or secure along multiple points to the cart, both in front of and behind the child.

Although strides have been made to provide a safe seating place in the cart, considerable shortcomings remain. It is desired that a tray assembly be design to function with 80-90% of all shopping carts across the US, making it practically universal while providing proper restraint for the child.

BRIEF SUMMARY OF THE INVENTION

It is an object of the present application to provide an adjustable tray assembly configured to extend between a backrest and a handle of a shopping cart. The assembly spans over the seat area and is configured to restrict the movement of a child once he/she is buckled into the seat area of a shopping cart. Additionally, the adjustable tray assembly is configured to provide a suitable surface to entertain the child while the parent is shopping.

An object of the present application is to provide an adjustable tray assembly designed to function with 80-90% of all shopping carts across the US, making it practically universal. Shopping carts are sized differently and therefore to compensate for changes in design, the adjustable tray assembly is configured to fold between pre-set locking positions to permit attachment to the backrest. Likewise, the adjustable tray assembly includes an attachment member that can selectively translate to properly grasp the handle of the shopping cart.

A further object is to provide a simple means of storage and portability. The adjustable tray assembly can fold over on itself combining the two distinct half portions. A user is then able to easily fit the assembly in a bag and carry it with its own handle.

Ultimately the invention may take many embodiments. In these ways, the present invention overcomes the disadvantages inherent in the prior art. The more important features have thus been outlined in order that the more detailed description that follows may be better understood and to ensure that the present contribution to the art is appreciated.

Referring now to the Figures wherein like reference characters identify corresponding or similar elements in form and function throughout the several views. The following Figures describe embodiments of the present application and its associated features. With reference now to the Figures, embodiments of the present application are herein described. It should be noted that the articles “a”, “an”, and “the”, as used in this specification, include plural referents unless the content clearly dictates otherwise.

Referring now to FIG. 1 in the drawings, a side view of an adjustable tray assembly 101 is illustrated attached to an upper seat area of a shopping cart 99. The embodiments and method of the present application is illustrated in the associated drawings. Assembly 101 is configured to extend over the seat area between the handle of cart 99 and the backrest of the seat area. A child sits in the seat area and is partially surrounded along the sides as he/she sits in the seat area. The child is provided a surface to interact with on assembly 101 which may assist in entertaining and in some way restraining the child while the adult shops. Additional features and functions are illustrated and discussed below.

The adjustable tray assembly of the present application is configured to further restrict the movement of a child once he/she is buckled into the front seat of a shopping cart, and to provide a suitable surface to entertain the child while the parent is shopping. The adjustable tray assembly of the present application is designed to function with 80-90% of all shopping carts across the US, making it practically universal.

Referring now to FIGS. 2-3 in the drawings, views of an adjustable tray assembly 101 are illustrated. Assembly 101 includes a tray portion 103 and an arm portion 104. A hinge 108 couples portions 103 and 104 together. Hinge 108 also permits the rotational adjustment of arm portion 104 relative to tray portion 103. Arm portion 104 is designed to surround a child within a hollow area 102, on at least three sides. The seat back of the shopping cart provides the fourth side to create the defined hollow area 102. The child rests within area 102 when properly installed on the shopping cart.

Tray portion 103 is a relatively flat component with a sunken central area 107 with raised sides 106. Sides 106 surround the perimeter of central area 107 as seen in the Figures. The full perimeter is preferred as this helps to prevent contents within area 107 from spilling. Within sides 106 may be external hooks/clips/mounts 111 that can be used to hold various child toys, soothing devices (i.e. pacifier), or other objects. These may be formed into sides 106, both inwardly or outwardly as seen in FIGS. 2 and 3. Some embodiments may include hooks/clips/mounts that are detachable.

The contour of the sunken central area 107 can be modified or molded to be at least one of flat, sloped, or curved. A cup holder (not shown) can optionally be formed in area 107. For example, the cup holder may be a depression or raised extrusion from the surface of area 107. The cup holder is configured to hold a cup, can, bottle, or other drinking vessel and may be formed to varied depths or shapes. A child can also use the surface of area 107 to play, eat, or draw on. The goal is that the child is occupied and “distracted” enough to not try to escape the basket or grab at random shopping items.

Further coupled to sides 106 is an attachment bar 113 which extends above sides 106 of tray portion 103. The shape of bar 113 is not herein limited to a cylinder as shown. Bar 113 is configured to accept and support one or more electronic devices by providing a surface to releasably couple to. In practice, a user (i.e. parent) may attach a phone with a shopping list to bar 113. Alternatively, a device for the child may be attached wherein the screen faces the child for entertainment. During storage of assembly 101, bar 113 may be used as a handle for transportation. It is understood that one or more bars 113 are possible and may be located adjacent to any sides 106 around the perimeter. Bars 113 may be molded into sides 106 or be detachable.

Arm portion 104 is hingedly coupled to a side of tray portion 103 through hinge 108. Arm portion 104 includes a body and a set of arms 105. Arms 105 are narrowed elongated sections that extend away from the body opposite hinge 108 and are configured to releasably couple to the backrest of the shopping cart seat area. Attachment thereto is accomplished through the use of latches 115. The body has a concaved or recessed profile extending between arms 105 to form hollow area 102.

Referring now also to FIG. 8 in the drawings, a perspective view of latch 115 is shown. Latches 115 are coupled to a distal end of arms 105 and include a lower and an upper curved member. The upper curved member 125 is rigidly secured relative to the arms 105. The lower curved member 127 pivots about an axis 129 between a closed position and an open position. A tensioning/compressing device (i.e. a spring) is used to maintain a closed position when at rest. An application of force to the lower curved member opens the latch and permits acceptance of the backrest of cart 99. When closed, the curved portions of the curved members overlap wherein the upper curved member is situated within the lower curved member.

The use of two curved members helps to prevent a child from lifting or pushing on arm portion 104 trying to dislodge latches 115. It is understood that latch 115 may be spring activated latch wherein opposing sides are biased about a spring. Other embodiments may include other means for opening and closure. Other such embodiments may or may not require any biasing elements. Of note is that latches 115 extend beyond the distal end of arms 105 so as to permit them to pass through and/or around the openings in the back rest of the seat area. In shopping carts, the backrest is typically a metal wire structure. However, some carts use thickened plastic with smaller holes. These holes may be too small for arms 105 to pass through, which necessitates the need for latches 115 to extend beyond the end of arms 105 so as to pass through the holes. In operation each arm 105 is secured to the backrest of the shopping cart.

Furthermore, portion 103 and arm portion 104 can be made from any type of material, however, it is desired that the material provides some flexibility to allow it to adjust to slight variations in shopping carts. Examples of materials may be plastics and composites.

Referring now also to FIGS. 4, 5, and 7 in the drawings, lower views of assembly 101 are shown. In this view an attachment member 117 is shown. Whereas latches 115 are used to couple the arms 105 to the shopping cart at the rear of assembly 101, member 117 is used to releasably couple tray portion 103 to the shopping cart. Member 117 is located on a lower surface 120 of tray portion 103 and is configured to translate forward and backward along a track 119. This allows member 117 to accommodate for the various depths of different shopping carts (depth being the distance between the main shopping cart handle and the rear of the child's seat at the backrest). Track 119 may be a recess or protrusion from the lower surface, or any combination therebetween. Track 119 permits longitudinal movement of member 117 both forwards and backwards. In some embodiments, member 117 may be free sliding within track 119 or may have standard set positions that lock or set the relative position of member 117.

Member 117 is configured to releasably couple to the handle of the shopping cart. It can accommodate the various diameters of the shopping cart handles, which may vary from approximately 0.75 inches to 1.50 inches in diameter, for example. To do this, member 117 needs to be adjustable in size. As seen in FIGS. 4, 5, and 7, member 117 is a C-shaped cylindrical body/device with opposing sides 118 that can pivot to open and close an opening therein. A slit is formed in the body to form the opposing sides. Member 117 includes a handle 121 coupled to at least one of the opposing sides 118. The handle 121 is positioned so as to be on the side closest to the user opposite hinge 108. This location assists adjustment and operation by an adult and hinders a child's ability to reach forward and around the side sufficiently to operate handle 121 so as to release member 117.

As seen in the Figures, the cylindrical body of member 117 is axially parallel to that of hinge 108. It is understood that the physical depiction of member 117 is not intended to be limiting as it is known that many different types of attachment methods may be used. Member 117 is ideally suited for quick attachment and detachment and is configured to facilitate the operation for an adult and hinder the operation of it by a child situated in the seat area of cart 99.

Referring now also to FIG. 6 in the drawings, a side view of assembly 101 is illustrated. Assembly 101 creates both a physical and even a psychological barrier that greatly restricts the movement of the child once seated in the shopping cart. It is noted that shopping carts are sized differently in the seats for children. As assembly 101 is configured to operate with a majority of shopping carts, it is preferred that assembly 101 be able to pivot arm portion 104 relative to tray portion 103. As seen in FIG. 6, arm portion 104 pivots about a hinge axis 123 of hinge 108. Hinge 108 can be of many types and varieties. Suitable types permit the arm portion 104 to pivot without causing increased potential to harm a child through pinching or sharp edges. A potential suitable example would be a living hinge. As seen in FIG. 6, arm portion 104 may pivot downward and/or upward to any angle, such as angle A (15 degrees) or angle B (30 degrees). Arm portion 104 is shown locked in a position defined by angle A. The angle may be freely adjustable or may be set/locked through one or more locking positions within hinge 108. The goal is to have the tray remain close to the child's torso instead of being so high that it's close to the child's neck.

Another feature of assembly 101 is that ability to be collapsible for ease of transportation. Arms 105 may be rotated completely downward such that the lower surfaces of tray portion 103 and arms 105 contact one another. These may be latched into a secured position wherein this closed or transporting position is one of the locking positions of hinge 108. In such position, member 117 is situated between arms 105. A user may then use bar 113 as a handle to carry assembly 101.

The particular embodiments disclosed above are illustrative only, as the application may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application. Accordingly, the protection sought herein is as set forth in the description. It is apparent that an application with significant advantages has been described and illustrated. Although the present application is shown in a limited number of forms, it is not limited to just these forms, but is amenable to various changes and modifications without departing from the spirit thereof.
