No. 11/901,924, filed Sep. 20, 2007, which is a continuation-in-part of the earlier U.S. Utility patent application entitled “FOOD OR DRINK TRAY”, Ser. No. 11/219,056 filed Sep. 1, 2005, the disclosures of which are hereby incorporated entirely herein by reference.
BACKGROUND OF THE INVENTION1. Technical Field
This invention relates generally to trays and more specifically to curvilinear shaped restaurant trays with hinged handles.
2. State of the Art
Servers at social gatherings and in restaurants transport ordered food and beverages from a kitchen or bar patrons. The server often uses a conventional circle tray and will place and balance several drinks and/or dishes of food on the tray. The tray is then transported to a table, for example, using a single hand to carry the tray. As is often done, servers balance the tray on one hand. This leaves the other hand free to handle checks or money and to move beverages and/or dishes of food from the tray.
Conventional trays are typically circular with a large diameter in order to accommodate many drinks and/or several dishes of food. Because of the size and the amount of dishes of food and beverages on the tray, it is difficult to balance, and particularly difficult to adjust for the weight shifting that occurs as food dishes and beverages are removed from the tray. Often, dishes or beverages fall to the floor and result in the breaking of the dishes or glasses and creating a mess that needs to be cleaned by a restaurant employee. Furthermore, the food or drinks have to be reordered, thereby creating a further delay in service to the patron. This is costly, time consuming, and embarrassing to the server.
Accordingly, what is needed is a restaurant tray that provides greater and easier ability to balance, support and transport the food and beverages and minimize the possibility of spilling any dish or beverage while still providing the advantages of enabling transport of large quantities of food or drink as with conventional trays.
DISCLOSURE OF THE INVENTIONThe present invention relates to a curvilinear shaped restaurant tray with a hinged handle. In a simple form, the tray may be a food or drink tray that includes a support substrate having a truncated crescent configuration. The substrate may include a top surface and bottom surface each extending along a first longitudinal axis and a second lateral axis perpendicular to the first longitudinal axis. The substrate may have a curvilinear shape, such as, but not limited to a heart shape. A handle may be hinged and allowed to rotate about an axis and/or be connected to and extend away from the bottom surface. The handle may extend transversely to the substrate. The handle may have a cross section having at least one of an oblong, an obround, an oval, a crescent, or other such configuration that may allow the user to orient the tray to a comfortable position to reduce wrist and arm fatigue. A length dimension of the cross section may extend in a range from zero to forty-five degrees relative to the first longitudinal axis. In use, the length dimension may thus be generally pointed at the server's shoulder or may extend at a predetermined angle in a range from zero to forty-five degrees relative to a line from the handle to the server's shoulder.
The handle may be connected to the substrate at a substantially laterally central position between lateral edges of the substrate. The handle may have a minimum spacing from each lateral edge in a range from three to seven inches. The handle may be connected to the substrate at a substantially longitudinally central position between longitudinal edges of the substrate. A maximum length of the tray may be in a range from fourteen to thirty-six inches. Another range of lengths may be from twenty-seven to forty inches. The maximum length of the tray may be in a narrower range from nineteen to twenty-four inches. The handle may have a length in a range from five to ten inches. The handle may alternatively have a length from three to seven inches. The length of the handle may be slightly less than two hand widths relative to a server using the tray.
The handle may have a tight hinge that is designed to move between at least two substantially stable positions. One of the stable positions may be an extended position with the handle extending in a transverse direction from the bottom surface of the substrate. The other stable position may be a folded position with the handle extending away from the substrate in a position transverse to the extended position of the handle, wherein the handle is substantially parallel with a plane of the substrate. The handle may have a cross section having at least one of an oblong, an obround, an oval, a crescent, or other such configuration that may allow the user to orient the tray to a comfortable position to reduce wrist and arm fatigue. A “rest” may provide a convenient contour for resting the tray on the user's hips or shoulders, thereby also reducing user fatigue. The handle may include a knob coupled to an end of the handle to aid the user in securely gripping the handle and controlling the tray. The tray may also have a raised outer edge acting as a rim to limit the sliding of articles placed upon the top surface of the tray. The rim also serves to substantially contain any food, drink or other item spilled within the tray to avoid messes and to minimize slipping hazards.
In another simple form, the present invention is directed to a food or drink tray system. The food or drink tray system may include at least one tray having an oblong configuration. The tray may include a top surface and bottom surface configured to rest on a shoulder of a user. A handle may be coupled to the bottom surface. The handle may extend transversely away from the bottom surface and/or away from a plane of the tray. The handle may have at least one of an obround, an oval, and a rectilinear cross section. A rib on a peripheral edge of the top surface of the tray may extend away from the tray in a substantially opposite direction from the handle. A handle aperture may be defined by structure of the tray extending through the tray. The aperture may also be defined by structure that forms at least a portion of the handle. The food or drink tray system may further include a plurality of similar food or drink trays. The plurality of food or drink trays may be conveniently stacked with a handle of a superjacent tray being received within the handle aperture of a subjacent tray.
The trays of the food or drink tray system may have a truncated crescent configuration or other configuration defined by any predetermined curvilinear perimeter. That is, the shape of the tray substrate or support surface may be of any shape which may be desirable for aesthetics or other reasons. However, elongated, oblong, and crescent shaped substrates provide certain advantages in accordance with the present invention. The trays of the food or drink tray system may include shoulder engaging structure on a bottom surface of the trays. The shoulder engaging structure may include an ergonomic surface modifying treatment for comfortably engaging a user's shoulder. The food or drink tray system may include one or more tray support having a receiving structure. The receiving structure may be configured to receive the handle and support the trays in a substantially horizontal position between periods of transport.
In one aspect, the tray of the present invention may include a restaurant tray including an oblong tray having a top surface and bottom surface, wherein the tray is configured to rest on the shoulder of a waiter. A handle coupled to the bottom surface and extending away from the bottom surface may be transverse to a plane of the tray. The handle may have a cross section with at least one of an obround configuration, a circle configuration, a diamond configuration, an oval configuration and a rectilinear configuration. The handle may have a length sufficient for two hands to grasp the handle. The handle may also be slightly longer than a single hand width in order for a proximal end of the handle to engage the user's forearm for greater stability. The handle may have a length within the range of at least two female hand widths to two male hand widths. Additionally, the oblong tray may include at least one of a truncated crescent configuration, an oval configuration, an obround configuration, a rectangular configuration and/or any combination thereof. The top surface of the tray may have at least one beverage recess for retaining a beverage within the at least one beverage recess.
The tray of the present invention may further include a plurality of beverage recesses and the tray may include a rib, wherein the rib is coupled to a peripheral edge of the tray and extends away from the tray in a substantially opposite direction from the handle. The handle may include a handle base plate configured to be coupled to the bottom surface of the tray. Additionally, the tray may further comprise a handle aperture extending from the top surface through the tray including the bottom surface, and at least partially into the handle. Thus, the handle aperture may be configured to receive a handle from another restaurant tray so as to enable stacking of the trays.
In another simple form, the invention may include a method of using of a food or drink tray. The method may include holding a handle that extends transversely from a bottom surface of tray with at least one first hand. The method may include supporting a portion of the bottom surface of a tray on a shoulder corresponding to the hand holding the handle. That is, a shoulder on the same side of the body as the hand holding the handle of the tray. The method may include leveling a top surface of the tray by raising or lowering the hand holding the handle. The portion of the bottom surface of the tray placed on the shoulder may form a pivot point and the hand may pivot the tray using the handle.
Thus, the method may also include rotating the tray inwardly or outwardly relative to the user's body by pivoting the tray on the shoulder. In one aspect, the method may include regularly supporting a majority of the tray and the objects thereon inwardly of an outermost edge of a user's shoulders. The method of using the tray may include increasing control of the tray by applying leverage to the handle to balance the tray as items are removed from the tray. The method may also include holding the handle with a second hand in addition to holding the handle with the at least one first hand for increased control.
In yet another aspect, the present invention may include a method of using a restaurant tray. The method may further comprise the steps of pivoting the tray when navigating through highly congested spaces, wherein the portion of the bottom surface of the tray placed on the shoulder forms a pivot point and the hand pivots the tray using the handle. The method may include balancing the tray as items are removed from the tray.
In another aspect of the present invention may include a method of using a food or drink tray, the method comprising rotating a rotatable handle about a hinge from a folded position to an extended when the tray is empty; resting the tray on one of a server's hips and shoulder while the handle is gripped by the server; filling the tray with one of food items, drink items and combinations thereof; carrying the tray to a table; rotating the rotatable handle to a folded position to rest the tray on the table; and unloading the tray.
The foregoing and other features and advantages of the present invention will be apparent from the following more detailed description of the particular embodiments of the invention, as illustrated in the accompanying drawings.
As discussed above, embodiments of the present invention relate to a food and/or drink tray that may be used as a restaurant tray. As shown in the perspective view of
As shown in
As shown in the perspective view of
The handle section may have a length dimension of approximately one inch at the small section to approximately one and three fourths inches at the large section. The handle section may have a width dimension of approximately two thirds of an inch at the small section to approximately one and one sixth inches at the large section. It is to be understood that other less tapered or non-tapered configurations may be implemented. Other dimensions inside or outside the above described ranges are also considered to be within the scope of the invention.
The substrate 12 may be oblong in configuration. Thus, the configuration of the tray enables a server to more easily support and balance the tray in close proximity to the server's body. This is especially advantageous as food or beverages are removed from the substrate 12. The configuration of the substrate 12 may be of any oblong configuration such as, but not limited to, a crescent configuration, a truncated crescent configuration, an oval configuration, an obround configuration, a rectangular configuration, or any other oblong configuration.
The substrate 12 of the tray may have any of a variety of dimensions. However, certain ranges of dimensions provide certain advantages to the server 17. For example providing the substrate of a width and locating the handle generally in a center of that width has the advantage of improved lateral balancing, or balancing about a longitudinal axis in a fore and aft direction. In this regard, the handle may have a minimum spacing from each lateral edge in a range from three to seven inches. The range may be from one to twelve inches. The handle may also be positioned in a fore and aft plane that extends through a center of gravity of the tray 10 or through a center of gravity of a predicted loaded tray. While servers will vary in size and breadth of shoulders, this range has the general advantage of enabling a center of mass of the tray and/or objects on the tray to be regularly located inside of an outer edge of the server's shoulder indicated by line 48 in
While the tray substrate 12 may have any of a variety of dimensions, and the handle 16 may be connected to the substrate 12 at a substantially longitudinally central position between longitudinal fore and aft edges of the substrate, it is to be understood that other positions of the handle in the fore and aft directions are also possible. One of the goals achieved by the present invention is to enable distribution of part of the weight on the shoulder. For example, while relatively short trays and trays being handled by servers with long arms may be controlled easily enough with the handles 16 coupled generally centrally in the fore and aft direction, longer trays may be more easily controlled with the handles 16 positioned slightly forward of the center and/or may have angled handles or portions thereof. In fact, positioning and angling of handles may be applied to any length of tray. The trays of the present invention may have a maximum length in a range from fourteen to thirty-six inches. A broader range from ten to forty-eight inches is more inclusive and may have some specialty applications. With the longer trays the handle may be coupled at a position two thirds or more of the overall length from a rear end edge of the substrate 12.
As shown in the bottom plan view of
Likewise, the handle 16 may be removably or permanently coupled to the handle base 40 by similar coupling mechanisms. For example, and without limitation, the handle base 40 may be integrally molded or shaped together with the handle 16. The handle 16 may be coupled to the base in various ways, including, but not limited to, screws, bolts, clips, a slide-lock, other fasteners, or fastening mechanisms. For example, glue or other adhesives or bonding agents may be used. Any of various types of welding may be implemented including heat welding and metal welding. The base 40 may be coupled to the handle 16 by press fit, snap fit, or frictional engagement.
Furthermore, the handle base 40 may be coupled to the handle 16 by a hinge and a compliant member locking device. The compliant member locking mechanism may include a snap lock mechanism, for example. In this particular configuration, the handle base 40 may be coupled to the bottom surface 21 of the substrate 12, with the handle 16 rotated away from the base into a position of use. The handle 16 may be configured to be locked into place in this position by the compliant member locking mechanism. Between uses, the compliant member locking mechanism may be unlocked to release the handle 16 into its non-use position. When unlocked, the compliant member locking mechanism allows the handle 16 to be rotated into a position substantially parallel with the substrate 12 to provide more efficient storing and/or transport of the food or drink tray 10.
The handle 16 may be coupled to the substrate 12 at any location on the bottom surface 21 that enables a server 17 to properly balance the tray by use of the handle 16 and a shoulder 20 of the server 17. For example, when the substrate 12 has a particularly long configuration, the handle may be coupled at a position approximately one third back from a front end edge of the substrate 12. Thus, the server can support the substrate on his or her shoulder 20 at a location two thirds back from the front end edge of the substrate so that the weight of the tray and any objects thereon may be supported at two generally evenly distributed locations by the handle and the server's arm and the server's shoulder 20. Similar to the hinged connection described above, in any of the configurations of the tray 10 in which the handle is removably attached to the substrate, the handles 16 may be separated from the substrates 12 during storage or other periods of non-use.

Referring to the side view of
Accordingly, the present invention is also directed to an overall system that may include at least one tray 10, but which may also advantageously include a plurality of like trays that are capable of being easily stacked and separated during both use and non-use. The trays 10 of the system of trays may have handles and one or more of the additional features described above with regard to the individual trays 10.
It will be understood that embodiments of the present invention are not to be limited to the specific components disclosed herein, but only by the appended claims. Accordingly, for example, although particular trays, handles, handle bases, beverage recesses, ribs and other components are disclosed, such components may include any shape, size, style, measurement, concentration, material, weight, and/or quantity as long as these are not limited by the claims.
Accordingly, the components defining any food or drink tray may be formed of any of many different types of materials or combinations thereof that can readily be formed into configured objects provided that the components selected are consistent with the intended operation of a food or drink tray. For example, the components may be formed of: rubbers (synthetic and/or natural) and/or other like materials; glasses (such as fiberglass) carbon-fiber, aramid-fiber, any combination thereof, and/or other like materials; polymers such as thermoplastics (such as ABS, Fluoropolymers, Polyacetal, Polyamide; Polycarbonate, Polyethylene, Polysulfone, and/or the like), thermosets (such as Epoxy, Phenolic Resin, Polyimide, Polyurethane, Silicone, and/or the like), any combination thereof, and/or other like materials; composites and/or other like materials; metals, such as zinc, magnesium, titanium, copper, iron, steel, carbon steel, alloy steel, tool steel, stainless steel, aluminum, any combination thereof, and/or other like materials; alloys, such as aluminum alloy, titanium alloy, magnesium alloy, copper alloy, any combination thereof, and/or other like materials; any other suitable material; and/or any combination thereof.
Furthermore, the components defining any food or drink tray may be purchased pre-manufactured or manufactured separately and then assembled together. However, any or all of the components may be manufactured simultaneously and integrally joined with one another. Manufacture of these components separately or simultaneously may involve extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, and/or the like. If any of the components are manufactured separately, they may then be coupled with one another in any manner, such as with adhesive, a weld, a fastener (e.g. a bolt, a nut, a screw, a nail, a rivet, a pin, and/or the like), wiring, any combination thereof, and/or the like for example, depending on, among other considerations, the particular material forming the components. Other possible steps might include sand blasting, polishing, powder coating, zinc plating, anodizing, hard anodizing, and/or painting the components for example.
Additionally, while it has been shown that the handle 16 is coupled to the substrate 12, particular embodiments of a food or drink tray 10 may include a substrate 12, a handle 16, and a rib 14, which are each integral with each other through means such as injection molding, or other processes that provide for a single piece with each component integral with one another.
Another particular embodiment of the present invention may include a method of using a food or drink tray. The method may include the steps of holding a handle with at least one hand, placing a portion of a bottom surface of a tray on a shoulder of the server that is on the same side of the server's body as the one hand holding the handle, and leveling a top surface of the tray by raising or lowering the hand holding the handle. This enables the server to have better control of the tray with two points of support and a handle providing leverage to better control movement of the tray. It is to be understood that the server may regularly choose to rest the tray on his/her shoulder only occasionally.
Additionally, the method may also include the step of pivoting the tray inwardly or outwardly relative to a center of the server's body about a pivot point 23 on the server's shoulder when navigating through highly congested spaces. As shown in
As food dishes and/or beverages are removed from the tray, the method may also include the step of balancing the tray at the moment the items are removed. This step is more easily accomplished with trays according to the present invention and is useful, for example, in situations where the server has beverages on the tray. In these situations, patrons may remove beverages from the tray on their own without warning to the server. Likewise, patrons may replace full glasses with empty glasses. Such situations provide for a constant change or shift in weight distribution on the tray. Hence, the use of a shoulder and a handle according to this method advantageously provides greater stability, control, and balancing. With the handle rigidly coupled to the substrate the method includes increasing control by applying leverage to the handle to balance the tray as items are removed from the tray. The result is a reduced number of spills of the beverages and/or food.
The method may also include sensing or determining a position of the tray by receiving tactile sensory feedback regarding an orientation of a longitudinal or other aspect of the cross section of the handle. That is, for example, by noting that the handle section is longitudinally aligned in a particular direction, the server may determine that the tray needs to be shifted inwardly or outwardly based on a previously memorized positional relation between the handle cross sectional orientation relative to the tray.
The step of holding the handle according to a method of the present invention, may include holding the handle with two hands. This is particularly beneficial when the tray is holding heavy food dishes and/or beverages. Use of two hands in accordance with this step may advantageously provides even greater ability to hold, level, control, and balance the tray.
In accordance with both the apparatus and the method, the handle 16 extending transverse or vertical relative to a plane of the substrate 12 also allows for a more natural grip, as opposed to the severe bending at the wrist which is required with conventional trays that have no handles. The present invention thus helps to avoid injury associated with such bending of the wrist, especially under heavy loads.
It will be understood by those of ordinary skill in the art that the order of steps in the method of use are not limited to the particular order in which they are disclosed, but may be adapted to the most efficient manner required for the particular use of the food or drink tray.
The handle 76 may have a tight hinge 80 that is designed to allow the handle 76 to move between at least two substantially stable positions. One of the stable positions, as shown in
The rib 74 is configured to substantially limit the sliding of articles placed upon the top surface 71 of the substrate 72. The rib 74 acts as a well to substantially contain any food, drink or other item spilled within the tray 70 to avoid messes and to minimize slipping hazards. The handle 76 preferably has at least one knob 78, as shown in
