Title: Tray

Description:
TECHNICAL FIELD 
     The present invention relates to trays and in particular to trays providing improved stability. 
     The invention has been developed primarily for use as a tray which provides capability for improved weight distribution of beverages or foodstuffs and greater stability for ease of carriage with a single hand and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use. 
     BACKGROUND 
     The are numerous examples of trays designed for carriage of beverages and/or foodstuffs in one hand, including that of the simple tray comprising a planar, generally circular, support portion or surface where the beverages or foodstuffs are loaded. The user then must lift the tray from the edges and carry the tray as shown in  FIG. 1 . Alternatively, the user may is attempt to, whilst maintaining the tray balanced, position their hand underneath the tray at the centre of mass in the horizontal plane to balance the load. It will be appreciated that this can be a difficult task where the load is heavy, such as for a number of filled beer glasses, and the user must exert significant care over maintaining the tray balanced whilst waking. 
     Attempts at improvement over the simple tray include, those described in U.S. Pat. Nos. 3,504,832; 3,941,286; 4,744,597; 5,119,967. 5,259,528; 5,346,070; 5,355,787; 5,421,459; 5,971,139; 6,109,580; and 7,000,799; and U.S. design Pat. No. D529,764. It is apparent, however, that none of these provide solution to the problem of being able to provide secure and stable manipulation of the tray without difficulties associated with the location of the centre of mass of the beverages and/or foodstuffs making balancing of the load difficult. In most cases, the location where the tray is held is significantly below the centre of mass of the load, therefore the user must constantly be aware of the load so that the tray does not tip. A further difficulty with these improvements is that the user must still lift the tray whilst loaded in order to grasp or place their hand underneath the tray at the designed location for carriage. A solution to the need for lifting the tray first is to provide a central handle that can be grasped from above, however, if this handle is located below the likely centre of mass (in the vertical plane) of the load, then again significant care is required to lift the tray without it overbalancing whilst the user places their hand underneath the tray for carriage. Whilst it can be envisaged that the handle can be positioned above the likely centre of mass of the load via a central pole, it will be appreciated that this is undesirable as convenient storage of a plurality of like trays becomes difficult and/or space inefficient.

     DETAILED DESCRIPTION 
     With reference to the figures, disclosed herein is a tray  100  adapted to be securely and stably carried by a hand of a user. In one arrangement, the tray comprises a support portion  101  having an upper surface  103  adapted for supporting the beverages or foodstuffs. A wall portion  113  extends upwardly from the upper surface  103  of the support portion  101 . A raised portion  107  is connected to the wall portion  113 . The raised portion has upper and lower surfaces ( 109  and  111  respectively) wherein the lower surface  111  of the raised portion  107  is located above the upper surface  103  of the support portion  101  when the tray  100  is in an operable position. The raised and wall portions  107  and  113  defining a recess  117  which is laterally accessible. The raised portion  107  is adapted to be gripped by the hand of the user whereby the thumb of the user engages the upper surface of the raised portion and the recess  117  is adapted to receive the fingers of the hand of the user so as to enable the lower surface  111  of the raised portion  107  to be engaged by the fingers of the user at the same time that the thumb of the user engages the upper surface  109 . 
     In the following description, the tray is described with reference to a service tray, although, it is envisaged that the tray is not limited to this usage and may be use in other s situations and environments and for alternative applications as would be appreciated by the skilled addressee. For example, the tray may be used for private and/or personal use. 
     Referring to the drawings, particularly  FIGS. 2 and 3 , a service tray  100  includes a support portion  101  having upper and lower surfaces ( 103  and  105  respectively) adapted for supporting beverages or foodstuffs. A raised portion  107  is adapted to receive the hand (shown in  FIG. 7 ) of a user having upper and lower surfaces ( 109  and  111  respectively), wherein the lower  111  of the raised portion  107  surface is higher that the upper support surface  103  of the support portion  101 . The raised portion  107  is connected to the support portion  101  by an wall portion  113 . The raised portion  107  enable the service tray to be carried by the user at or near the centre of mass in both horizontal and vertical planes for stable control of the movement and balance of the service tray. 
     In the arrangements shown in the figures, the support portion  101  is adapted to provide unobstructed access for the user to place their hand (not shown) under the raised portion  107  to engage their hand with the lower surface  111  thereof via recessed portion  117  and lift the service tray  100  (either laden or unladen) without requiring any intervention from their other hand. To facilitate this in the present arrangement, the support portion is substantially U-shaped when viewed from above. In this arrangement, the raised portion  109  where the user engages the tray with their hand is located at the centre of mass of the service tray, and the beverages and or foodstuffs may be arranged around the U-shaped support portion in such a way as to maintain the centre of mass of the laden tray at the location of the raised portion. A further advantage of the U-shaped service tray is that the user&#39;s wrist and forearm are received by the recessed portion  117  and do not obstruct the service tray. This also allows for the user to maintain a favourable angle between their forearm and upper arm (for example in the range of approximately 45 to 135 degrees, or approximately 50 to 130, 55 to 125, 60 to 120, 65 to 115, 70 to 110, 75 to 105, 80 to 100, or approximately 85 to 95 degrees) without being obstructed by the service tray itself, whereby greater control over the tray can be achieved. 
     The support portion  101  has a peripheral retaining lip  115 . The retaining lip in the figures is shown as a peripheral side wall with a height approximately equal to the height of the wall portion  113 , although it will be appreciated that further arrangements may be envisaged where the height of the retaining lip is less or much less than the height of the wall portion  113 . As shown in the figures, the retaining lip  115  is shown as being contiguous with the wall portion  113 . It will be appreciated that the primary use for the service tray is in a bar or restaurant situation to improve the ease with which staff or patrons can carry large numbers of drinks with only one hand and without requiring their other hand to position the tray. In this manner it is envisaged that the staff or patron can carry two like trays laden with beverages and/or foodstuffs without difficulty. The service tray is generally dimensioned to accept a variety of beverage containers including, but not limited to wine glass, low-ball and/or high-ball glasses, midi and/or, schooner glasses, half-pint and/or pint glasses, bottled beverages such as pre-mixed beverages or beers, wine bottles and other suitable beverage containers. Typically the largest container in a bar situation would be the pint glass, which generally has dimensions of approximately 150 mm in height with a base diameter of about 60 to 80 mm and a maximum outer diameter of about 80 to 100 mm. 
     The dimensions of the service tray are such that it is able to accommodate the typically largest sized beverage container encountered in the service environment, therefore generally the width of the U-shaped support surface  103  of the tray  100  would be approximately 80 to 100 mm, although it will be appreciated that greater or smaller widths may be envisaged depending on the user&#39;s requirements. For example, one or more portions of the support surface  103  may be configured to accommodate one or more wine or spirit bottles, and the configured portions may be so configured that the wine or spirit bottle is located and or retained in the configured portion. 
     Referring now to  FIG. 6 , there is shown a cut-away view of the service tray  100  taken along line A-A of  FIG. 4 . The raised portion  107  has an arcuate formation  119  with upper surface  109  and lower surface  111  for engagement of the user&#39;s hand  121  during carriage of the service tray as shown in  FIG. 7 . 
     The raised portion  107  is adapted to be gripped by the hand  121  of the user whereby the thumb  127  of the user engages the upper surface of the raised portion and the recess  117  is adapted to receive the fingers  123  of the hand of the user so as to enable the lower surface  111  of the raised portion  107  to be engaged by the fingers  123  of the user at the same time that the thumb  127  of the user engages the upper surface  109 . 
     It has been found that the an arcuate formation  119  on the raised portion  107 , and in particular an arcuate, contoured formation which resembles the natural curve of the upturned open palm of a users hand  121 , that the majority of the load bearing is shifted anatomically from the user&#39;s fingers  123  and wrist  125  to the user&#39;s upper arm and biceps (not shown), which is a much stronger position which affords greater control over the stability and manoeuvrability of the service tray. As can be seen, in the present configuration, the users fingers  123  engage the lower surface  111  of the contoured formation  119  of the raised portion  107  to lift and support the service tray. The user&#39;s thumb  127  grasps the raised portion  107  of the service tray  100  by engaging the upper surface  109  of the contoured formation  119  of the raised portion  107 . Arcuate formations  129  and  131 , which are disposed at leading edge portion of raised portion  107  enable the leading edge portion of raised portion  107  to be engaged by a gripping face  128  of the user&#39;s thumb  127  and the portion of the user&#39;s hand adjacent the gripping face  128  as depicted in  FIG. 7 . Formations  129  and  131  also provide for the user&#39;s comfort and additional control and stability. They also increases the rigidity of the connecting wall portion  113 . It will be appreciated that other suitable arrangements of the raised portion and the contoured formation may be envisaged without detracting from the spirit of the invention. 
       FIGS. 8 and 9  show the significant improvement in the weight distribution of the presently described service tray over prior art service trays due to the improved location of the centre of mass of the laden tray with respect to the user&#39;s engagement location for carriage of the tray.  FIG. 8  shows a side view of a prior art service tray in the form of a simple flat tray  150 . The tray is laden with three beverage containers  151  (eg. pint or schooner glasses of beer or other beverage). Whilst the beverage containers  151  may be readily arranged on the tray such that the centre of mass  153  is in the approximate centre of the tray in the horizontal plane, it can be appreciated that the centre of mass of mass  153  of the laden tray  150  in the vertical is at a significant height  155  (designated as distance “a” in the figure) above the tray  150 . To carry the tray  150 , the user must first lift the tray  150  with both hands from the edges  157  and to carry the tray with only one hand, they must then manoeuvre their hand underneath to engage the tray at the approximate centre of mass of the laden tray in the horizontal plane (approximately at location  159 ). The distance that the user must move their carrying hand underneath the tray whist supporting it with both hands is designated “b” in  FIG. 8 , and is approximately half the width/radius of the tray. However, since the distance  155  from the engagement location  159  and the centre of mass of the laden tray is significant, there is a large tendency for the tray to tip or overbalance whilst the user is manoeuvring their hand to the engagement location  159  and whilst the user is walking with the tray  150  carried in their one hand. It will readily be appreciated that, once the user has positioned one such laden tray  150  for carriage with one hand, they are not able to repeat the process with a second like laden tray  150  to be carried in their other free hand, and in any event, even if the user acquired assistance to place a second laden tray on their free hand, the user would need to exercise great care in maintaining the balance of one or both laden trays as they were carried. Furthermore, the user would also be unable to place the tray down on a horizontal surface without requiring the assistance of their other hand. The maintenance of the balance of the tray is made difficult due to the vertical distance  155  of the laden tray from the engagement location  159 , and becomes increasingly more difficult as the tray is laden with greater numbers of items or items of increased weight. 
     Turning now to  FIG. 9 , there is shown a section view (taken along line A-A of  FIG. 4 ) of the service tray  160  laden with beverage containers  161  having a centre of mass  163 . In the first instance, and as has been previously described, the user does not need two hands to lift the service tray, but simply engages the tray at the engagement location  165  with a hand and lifts the tray directly. Since the weight of the beverage containers  161  placed on the service tray  160  may readily arranged to be evenly distributed such that the centre of mass in the horizontal plane is approximately coincident with the engagement location, and therefore the distance “b” that the user needs to move their hand after lifting the tray to be able to balance it with one hand is reduced to zero i.e. the user is able to directly engage the tray with a free hand at the centre of mass in the horizontal plane and then lift the tray without the need for assistance from their other hand. Further, since the engagement location  165  is elevated/raised with respect to the bottom surface  167  of the service tray  160 , the vertical distance  169  between the user&#39;s engagement location  165  and the centre of mass  163  of the laden tray is significantly reduced. This therefore significantly lowers the tendency of the laden service tray to tip or overbalance and thus requires significantly less effort from the user to maintain the balance of the tray, providing a much improved stable platform for carriage of the beverage containers whilst the user moves about. It is even possible that, for low profile beverage containers such as low-ball glasses, spirit glasses or cognac glasses for instance, the centre of mass  163  can be lower that the engagement location  165 , therefore requiring no effort from the user at all to balance the service tray, as it “hangs” from the user&#39;s hand. The only effort required in this situation is the lifting of the weight of the laden service tray  160  which, as has been previously described, is conveniently distributed through the user&#39;s entire aim. Furthermore, since the user does not require two hands to lift and or initially stabilise the service tray on their one hand, it will be appreciated that the user can readily lift and carry two like laden service trays  100  with ease. 
     It will be appreciated that the user would readily load the service tray in the shown configurations to locate the centre of mass  163  at the centre of the tray  160  to be coincident with the raised portion  107  and the engagement location  165  to balance the weight for ease of carriage.  FIGS. 10 to 13  (where like features are indicated by like reference numerals) show perspective and top plan views of the service tray  160  with various load configurations and the relative centre of mass  163  of the laden service tray with 3, 4, 5, and 6 beverage containers  165  (eg. beer glasses) respectively. 
     In use for the carriage of a number of beverage, the user loads the beverages to be carried onto the support surface  101  of the tray  100  in a configuration such that the load of the beverages is evenly distributed and the centre of mass of the laden tray is coincident with the raised portion  107 , for example as described with reference to  FIGS. 10 to 13 . The user then inserts the fingers of their preferred hand into recess  117  of the tray  100  and engages the palm of their hand with the lower surface  111  of raised portion  107 . The user then engages the gripping face  128  of their thumb  127  with the upper surface  109  of raised portion  107  thereby to grip the leading edge of the raised portion. The user is then able to lift the laden tray  100  and carry the beverages stably with one hand. 
     The service tray disclosed herein, may formed from a plastics material and may be formed by moulding or injection moulding techniques. In other arrangements, the service tray may be formed from thermo-formed plastic, pressed metal or laminated fibres such as wood. The service tray  100  may be nestable or stackable for ease of storage of two or more, or a plurality, of like service trays as shown in  FIG. 14 . The service trays  100  may optionally include ridges  167  to minimise the amount by which the nested trays wedge (i.e. stick) together due to draft angle of the peripheral side wall. The ridges  165  may be angled with respect to the retaining lip/side wall  115  and an angle in the range of about 6 to 10 degrees is desirable. In other arrangements, the angle of the ridges may be approximately 7 to 10. 8 to 10, 7 to 9 6 to 9, or approximately 7.5 to 8.5 and may be approximately 6, 6.5, 7, 7.5, 8, 8.5, 9, 95, or 10 degrees. A further advantage of the service tray is that the user is able to load a top service tray of the stack with beverages and easily lift the loaded tray from the stack by inserting their hand along arrow  180  to engage the raised portion of the top service tray and lift the tray as previously described. 
     Due to the configuration of the raised portion as shown in the figures, the service tray may be readily lifted from the stack of like service trays in the manner previously described without having to first use two hands to separate a tray from the remaining trays in the stack. 
     Shown in  FIG. 15  is a further arrangement of a service tray  170  similar to the arrangements described above but further comprising dividing portions  171 . The dividing portions are adapted to divide the support surface into a plurality of compartments  171  which may be used for the carriage of foodstuffs. The dividing portion  171  may in further arrangements be removable. 
     It will be appreciated that the methods/apparatus/devices/systems described/illustrated above at least substantially provide a service tray with improved stability and handling ease. 
     The arrangements of the service tray described herein, and/or shown in the drawings, are presented by way of example only and are not limiting as to the scope of the invention. Unless otherwise specifically stated, individual aspects and components of the service tray may be modified, or may have been substituted therefore known equivalents, or as yet unknown substitutes such as may be developed in the future or such as may be found to be acceptable substitutes in the future. The service tray may also be modified for a variety of applications while remaining within the scope and spirit of the claimed invention, since the range of potential applications is great, and since it is intended that the present service tray be adaptable to many such variations.
