Abstract

A tray for carrying food, beverages or other items has a surface partitioned to carry such food and beverage products. At least one corner of the tray extends laterally outward from the surface of the tray. This extension serves to engage the arm of the user, thereby eliminating rotational moments in two horizontal axes of the tray and preventing rotation of the tray about the two horizontal axes.

Description

CROSS REFERENCE TO RELATED APPLICATIONS
• This application claims priority from provisional application No. 60/666,008 filed on Apr. 20, 2005 to the extent allowed by law.
FIELD OF THE INVENTION
• The present invention relates to a tray for carrying food, beverages, and the like that allows a user having partial or normal arm functions to support the tray in a horizontal position with one arm.
BACKGROUND OF THE INVENTION
• Trays for carrying food and beverages from a food dispensing area, such as a cafeteria line, to an eating table are commonly used in food service establishments such as cafeterias. Conventional trays have consisted of a shallow flat support surface with slightly raised edges or rims used for carrying food and beverage items. Additionally, many of these conventional tray designs have included various sized partitions and beverage container holders to keep food and beverage items stationary on the tray during transport.
• Individuals with partial arm functions, such as partial or full amputees, those with brachial plexus injury, paraplegics, and anyone with an illness, injury or condition who is required to support and balance his/her food and beverage tray with one hand or with only minimal support from the second hand, experience serious difficulty in balancing a tray full of food and beverages while walking to an eating table. Presently available food and beverage trays do not provide balance or stability when used by individuals with partial arm functions.
• Various designs for trays or devices for carrying food and beverages are disclosed in the prior art. U.S. Pat. No. 6,832,687 entitled “Beverage and Food Carrier” and U.S. Pat. No. 6,752,288 entitled “Expandable Serving Tray” disclose food trays and carrying devices for persons with normal arm functions. Neither of the disclosures in these patents teach or suggest a tray which is designed for use by people with partial arm functions. Further, none of the food trays disclosed in the prior art are designed to be supported by a user in a manner that reduces the twisting moment acting on the tray, thus making the tray easier to carry.
SUMMARY OF THE INVENTION
• The object of one embodiment of the invention is to provide a tray device which can be used by people with partial arm functions to help increase their independence. The improved tray includes an ergonomic shape with contoured edges for easier carrying. An optional feature of the present invention is the provision of enlarged rims for better gripping of the tray.
• An important feature of an embodiment of the tray is an aperture structure that allows for arm placement by the user. The aperture is strategically positioned on the tray to allow the user to slide an arm through the aperture and rest the underside of the tray on the corresponding forearm. This feature allows easier transport of food or beverage items through improved support of the transported items as most of the force from the weight of the items is shifted back to the forearm and bicep muscles of the user. The tray of this embodiment is also designed to allow the user to locate the side of the aperture above the bent elbow if necessary for additional support while in use. The other “free” hand can either hold onto the tray for further stability or be used for other activities. The tray can also be reversible, having two opposite partitioned surfaces for use with either the left or right hand extended through the aperture structure.
• The contoured edges of another embodiment of the tray provide for additional support by allowing the user to rest the tray against the hips or abdomen. This reduces the weight necessary to be supported by the user's arm muscles alone and provides for easier transport of items on the tray. The rims or edges of the tray are wider and thicker than conventional trays in an embodiment which allows the user's fingers to clasp on and hold the tray at the edges comfortably. Less effort is required in gripping a larger surface area. In another embodiment, the tray has one or more grip handles extending downward from the rim of the tray allowing a user with a deformed or clawed hand to grasp the tray more easily.
• A cup or beverage holder is also incorporated into the design by a shape specific partition. The cup holder therefore allows for easier carrying of an open drink without the spillage concerns of prior tray designs. The tray is designed to be light, durable, and easy to use.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
• FIGS. 1-5 show different views of the illustrated embodiment of thefood tray device10. Thetray10 is manufactured from a light durable material or combination of materials that provide for improved resistance to wear and tear and for ease of carrying, such as plastic, paperboard, or the like. Thetray10 is contoured in the horizontal plane to allow a plurality oftrays10 to be neatly stacked one on top of the other. Eachtray10 has afirst surface12 adapted for carrying food, beverages or other products. Thefirst surface12 of thetray10 is divided into at least onepartition13, having anedge16 forming arim18 that extends vertically outward from thesurface12 to define a cavity for holding food, beverage, and other items. In the illustrated embodiment, the corners ofrim18 are rounded; however, other corner shapes may be adopted. Thepartition13, designed to keep food products on the tray, can be any desired number, size or shape. The food partition orpartitions13 in the illustrated embodiment can hold a regular size plate of food and can also be used to carry beverages if desired. Thefirst surface12 of the illustrated embodiment also includes acup holder partition14 specifically shaped to hold a cup or other beverage container. Thetray10 also includesrounded edges16 on the outer boundary of the tray. Theserounded edges16 extend to include enlargedrims18 for easier gripping of the tray when necessary.
• The illustrated embodiment ofFIGS. 1-5 includes an extendingexterior portion19 having anaperture20 extending through thetray10, theaperture20 strategically positioned near a side or corner of thetray10. This structure is designed and located to allow a user to slide his or her arm through theaperture20 to rest the underside26 (FIG. 2) of thetray10 on the forearm of the user. The user slides an arm through theaperture20 until theside28 of theaperture20 is located just above the elbow or otherwise in a comfortable position, such that the forearm and hand supports theunderside26 of the tray. Theaperture20, as shown, allows the user to provide a strong support for thetray10 while transporting items on the tray because the majority of weight of the transported items is shifted to the forearm and bicep of the user. The other “free” hand can either hold onto therim18 of thetray10 for further stability or be used for other activities.
• The user is not required to grasp the tray with one or both hands in order to transport the weight as with conventional tray designs. This makes the tray ideal for persons with partial arm functions or for amputees who can only make use of one arm. Thetray10 of the illustrated embodiment can also be reversible, having two opposite partitioned surfaces12 (FIGS. 1 and 2) for use with either the left or right hand through theaperture20. Theedges16 and raisedrim18 are part of an ergonomic design that helps to provide enhanced support for the user.
• The cup holder partition14 (FIGS. 1 and 2) is an optional feature of thetray10 design. The diameter and height of thecup holder partition14 is chosen so that any standard sized cup or a canned or bottled beverage will sit firmly in thecup holder14, preventing spillage. InFIGS. 1-5, thecup holder partition14 is strategically located close to theaperture20 to reduce the moment of force acting upon thetray10, thus making it easier to transport open beverages and other items on thetray10.
• FIG. 2 shows the second orunderside surface12 of the illustrated embodiment. Thetray10 is reversible and allows a user to support the tray via theaperture20 with either the right or left arm. Eachsurface12 is therefore functionally identical for the user.
• FIG. 5 shows a user carrying thetray10 and easily supporting weight from abottle21 partially filled with liquid as shown. Theside28 ofaperture structure20 is adapted to rest upon and be partially supported by the user's arm located just above the elbow. Thetray10, being thus supported on the user's arm, provides steadier transport of food or beverage products for persons with partial or normal arm functions where spillage may have occurred in prior tray designs. Support of thetray10 with one arm via theaperture20 reduces the moment of force and the rotational pull on the tray while in use. Adding weight to thetray10 at any point while supported by the user's arm will not result in tipping or spillage. In an embodiment of the invention, thesurface12 can also include an undulated or similar design molded into or otherwise applied to thesurface12 to limit movement and slippage of items on the tray.FIG. 6 illustrates the elimination of the rotational forces acting ontray10 along horizontal axes X (44) and Z (46), thereby preventing spills, when the illustrated embodiment is used as shown inFIG. 5.
• FIGS. 7, 8 and9 illustrate alternative embodiments of the food tray. The trays inFIGS. 7, 8, and9 are also manufactured from a light, durable material or combination of materials, that provide for improved resistance to wear and tear and for ease of carrying, such as plastic, paperboard or the like. The tray24 (FIG. 7) has asurface25 with at least onepartition27 for carrying food products. Thetray24 also includes anedge32 which forms a raisedrim34, extending vertically upward and around the surface, and at least twocorners40. Thecorners40 and theedge32 are part of an ergonomic design that provides enhanced support for the user by extending vertically outward from thesurface25 of thetray24 to form extended support surfaces36 of a contoured design. Theside38 of the extended exterior support surfaces36 is contoured to make contact with the user's body, partially extending around the hips and abdomen to provide further support while at the same time providing comfort for the user. The user is able to distribute more weight from the load through thetray24 onto the hips and abdomen, making transport of items on the tray much easier. The design of thetray24 allows extended support surfaces36 to be held under or over the user's forearms during transport of thetray24, thereby relieving stress on the arms and wrists. The raisedrim34 formed from theedges32 provides an added support feature. Therim34 allows easier gripping of thetray24 by the user, as minimal effort is required for gripping this larger surface area. Thetray24 ofFIG. 7 is contoured in the horizontal plane to allow a plurality oftrays24 to be neatly stacked one on top of the other.
• The second alternative embodiment inFIG. 8 also includes one or more cup orbeverage holders42 located at thecorners40 of thetray30, making it easier to transport beverages and other food items on the tray. This alternative embodiment also includes extended support surfaces36 for the same purpose as the extended support surfaces36 shown in the embodiment ofFIG. 7. Thetray30 shown inFIG. 8 andFIG. 9 also includes one or more grip handles48 extending downward from the rim of thetray30, the grip handles being adapted to be gripped by a user with a deformed or clawed hand. The grip handles48 extend laterally along the edge of thetray30 and are integrally formed with thetray30 in the illustrated embodiment, further providing improved support for the user and making it easier to transport items on the tray.
• Thetray30 ofFIGS. 8 and 9 is contoured in the vertical and horizontal planes to enable onetray30 to nest inside anadjacent tray30 when a plurality oftrays30 are stacked one on top of the other.
• In an embodiment of the invention shown inFIGS. 7, 8, and9, the surfaces25 (FIG. 7) and31 (FIG. 8) can also include an undulated or similar design molded into or otherwise applied to thesurfaces25 and31 to limit movement and slippage of items on the tray.
• The foregoing description of an illustrated embodiment of the invention has been presented for purposes of description, and is not intended to be exhaustive or to limit the invention to the precise forms disclosed. The description was selected to best explain the principles of the invention and practical application of these principles to enable others skilled in the art to best utilize the invention in various embodiments and various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention not be limited by the specification, but be defined by the claims set forth below.
