       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0016]    The present invention is best understood by reference to the detailed figures and description set forth herein. 
         [0017]    Embodiments of the invention are discussed below with reference to the Figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. For example, it should be appreciated that those skilled in the art will, in light of the teachings of the present invention, recognize a multiplicity of alternate and suitable approaches, depending upon the needs of the particular application, to implement the functionality of any given detail described herein, beyond the particular implementation choices in the following embodiments described and shown. That is, there are numerous modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive. 
         [0018]    It is to be further understood that the present invention is not limited to the particular methodology, compounds, materials, manufacturing techniques, uses, and applications, described herein, as these may vary. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to “an element” is a reference to one or more elements and includes equivalents thereof known to those skilled in the art. Similarly, for another example, a reference to “a step” or “a means” is a reference to one or more steps or means and may include sub-steps and subservient means. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than that of a logical “exclusive or” unless the context clearly necessitates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise. 
         [0019]    Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferred methods, techniques, devices, and materials are described, although any methods, techniques, devices, or materials similar or equivalent to those described herein may be used in the practice or testing of the present invention. Structures described herein are to be understood also to refer to functional equivalents of such structures. The present invention will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings. 
         [0020]    From reading the present disclosure, other variations and modifications will be apparent to persons skilled in the art. Such variations and modifications may involve equivalent and other features which are already known in the art, and which may be used instead of or in addition to features already described herein. 
         [0021]    Although Claims have been formulated in this Application to particular combinations of features, it should be understood that the scope of the disclosure of the present invention also includes any novel feature or any novel combination of features disclosed herein either explicitly or implicitly or any generalization thereof, whether or not it relates to the same invention as presently claimed in any Claim and whether or not it mitigates any or all of the same technical problems as does the present invention. 
         [0022]    Features which are described in the context of separate embodiments may also be provided in combination in a single embodiment. Conversely, various features which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination. The Applicants hereby give notice that new Claims may be formulated to such features and/or combinations of such features during the prosecution of the present Application or of any further Application derived therefrom. 
         [0023]    References to “one embodiment,” “an embodiment,” “example embodiment,” “various embodiments,” etc., may indicate that the embodiment(s) of the invention so described may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one embodiment,” or “in an exemplary embodiment,” do not necessarily refer to the same embodiment, although they may. 
         [0024]    As is well known to those skilled in the art many careful considerations and compromises typically must be made when designing for the optimal manufacture of a commercial implementation any system, and in particular, the embodiments of the present invention. A commercial implementation in accordance with the spirit and teachings of the present invention may be configured according to the needs of the particular application, whereby any aspect(s), feature(s), function(s), result(s), component(s), approach(es), or step(s) of the teachings related to any described embodiment of the present invention may be suitably omitted, included, adapted, mixed and matched, or improved and/or optimized by those skilled in the art, using their average skills and known techniques, to achieve the desired implementation that addresses the needs of the particular application. 
         [0025]    It is to be understood that any exact measurements/dimensions or particular construction materials indicated herein are solely provided as examples of suitable configurations and are not intended to be limiting in any way. Depending on the needs of the particular application, those skilled in the art will readily recognize, in light of the following teachings, a multiplicity of suitable alternative implementation details. 
         [0026]    Embodiments of the present invention will be described which provide a generally square-shaped shallow tray. Alternate embodiments may comprise trays with various other shapes such as, but not limited to, polygon, round, oval or freeform. Furthermore, the tray is configured with rounded corners and with a rounded intersection of the sides of the tray with the bottom of the tray. The tray is configured with loops attached/integrated on opposing sides of the tray. The loops are configured near the mid-point of a side with respect to the vertical and horizontal. In alternate embodiments, the loops may be located at any point laterally or vertically on the tray dependent upon the desired functionality and/or attitude during transport. In a non-limiting example, height of a leading loop may be lower than height of a trailing loop so that the leading edge of the trailing tray will tend to track higher than the trailing edge of the leading tray to aid in transport over soft media such as blown insulation. 
         [0027]    A coupling may be attached to the loop associated with the tray. A multiplicity of trays may be configured as a string or train of trays by connecting the trays together using couplings. A lead with a looped end or ends may be attached to a tray located at the end of the string of trays in order to provide a means for towing the string of trays. 
         [0028]    The rounded corners and rounded underside of the trays combined with the arrangement of the loops and couplings associated with connecting the string of trays enables the string of trays to maneuver around and over obstructions. 
         [0029]    The ratio of the side dimension with respect to the bottom dimension and the length dimension of the loops and couplings enables a string of trays to be pulled or pushed for traversing from one location to another location. In some embodiments, the length dimension of the loops on opposite ends of trays combined with the couplings and depth of trays may be such that they facilitate the stacking of trays and/or inversion of trays to act as lids while maintaining the functionality of towing and maneuverability. In general, placing the loops within the middle ⅓ of the vertical tray height allows for the coupling length to remain relatively short while still allowing for stacking and covering of adjacent trays. In some embodiments with the application of comparatively larger/deeper trays, the vertical alignment of the loops may be held lower or higher to enhance the ability of connected trays to transport heavier loads. 
         [0030]    The arrangement of the loops and couplings enable an end tray or trays to be flipped upside down and inserted into an adjacent tray or trays in order to cover and protect the contents of the covered tray. Furthermore, the trays may be rotated and stacked onto adjacent trays to form a compact stack of trays. The alignment and size of loops and couplings may allow for the nesting or covering without the need to disconnect adjacent trays. 
         [0031]    Alignment lips located on two opposing corners of the tray provide alignment of the tray when inverted and inserted into another tray to provide a covering. 
         [0032]    The loops and couplings are configured in such a way as to enable one tray to be inserted into another tray. 
         [0033]    A continuous ridge traverses around the outside perimeter of the tray in order to provide alignment and rigidity for stacking a multiplicity of trays to form a stacked tray assembly. 
         [0034]    In a stacked configuration, a void or empty space is provided for storage of tools, parts and supplies. 
         [0035]    A strap or a multiplicity of straps may be connected to a stacked tray assembly in order to transport the tray assembly as a single unit. Furthermore, strap or straps may be used for lowering or raising stacked tray assembly through an opening into an enclosed space (e.g. crawl space, attic, etc.) 
         [0036]    Non-limiting examples of alternative uses for tray include, as a head rest, knee pad or seating device. Furthermore, a multiplicity of inverted trays may be placed on the ground in order to provide a non-contaminated surface. Furthermore, a series of trays may be individually used to distribute or hold parts relating to wheels of a device (e.g. automobile) in order to facilitate maintenance and repairs and/or may be used for storing and transporting old or new components in order to provide a means for finding components and for preventing loss of the components. Non-limiting examples for using trays associated with an automobile include tire rotation, brake repair, brake maintenance, shock repair and suspension repair. 
         [0037]    For a stacked tray assembly, the top tray may be inverted and void of items in order to provide a covering. Furthermore, the inverted top tray may be removed and used in its inverted orientation as a seating device or knee cushion following transportation of the tray assembly. 
         [0038]    Trays may be used for a multiplicity of applications. Non-limiting examples for application of trays include building trades, IT, audio/video, phone, data, landscaping, harvesting, spelunking, tailoring, towing and manufacturing. Furthermore, trays may be used by jewelers, medical professionals, laboratories, tailors, garment industry, product assembly, auto repair and emergency response professionals. 
         [0039]    Tray is proportionally configured with respect to its dimensions and material of manufacture for providing a strong, yet lightweight device. Typical dimension ratios relative to shape, length, width, depth, loop and connector size are related to functionality yet widely flexible according to the particular application or industry. Furthermore, the device may be configured such that its cost for manufacture is relatively inexpensive. 
         [0040]    A multiplicity of trays may be linked via flexible couplings to form a tray assembly. 
         [0041]    A first end of a lead connected to a loop associated with a tray assembly enables transport of the tray assembly via application of a force to the lead. Furthermore, a second end of the lead connected to or hand-held by a person provides transport of the tray assembly in the person&#39;s direction of travel. Furthermore, the attached tray assembly may be transported through confined spaces and over irregular terrain. Tray assembly may traverse irregular terrain and maneuver around obstacles due to the rounded corners and smooth rounded bottom of the tray and the configuration of the linking mechanism between the trays. The ratio of linking mechanism connector size and overall length relative to a particular tray size or shape may allow the connected trays to be easily rotated and nested or flipped to act as a covering. Non-limiting examples of irregular terrain and obstacles include dirt, plywood, insulation, pipes, hoses, wires, bark, grass, concrete, smooth flooring, table top, roofing material, plastic sheathing and crushed rock, foundation corners, pier blocks, wood posts, building corners and trees. Furthermore, rounded corners and smooth rounded bottom provide for an easy-to-clean device. 
         [0042]    The coupled trays form a semi-rigid device with hinging provided by the couplings configured between the trays. Furthermore, the configuration of the tray assembly allows for independent movement of individual trays while the trays are connected. 
         [0043]    A tray may be inverted in order to form a cover for an adjacent tray. Furthermore, with a coupling device connecting the trays, a following tray may form a covering for an adjacent leading tray or a series of following trays may form a covering over a series of leading trays. 
         [0044]    A multiplicity of connected trays may be stacked or nested. Furthermore, stacking or nesting may be accomplished while the associated coupling devices are connected between the trays. 
         [0045]    A tray may be disconnected from a tray assembly (i.e. multiplicity of connected trays). 
         [0046]    A tray may be connected to a tray or a tray assembly (i.e. multiplicity of connected trays). 
         [0047]    A tray may be used to perform a multiplicity of operations. Non-limiting examples of operations include mixing, sorting and storing. 
         [0048]    A tray may be used as a seating device providing a place for a person to sit on. 
         [0049]    A tray may be used as a knee cushion providing a place for a person to kneel. 
         [0050]    A tray may be used as a head rest providing a place for a person to rest their head. 
         [0051]    Smooth interior concave corners reduce the tendency of inaccessible areas to large or gloved hands to provide access to items located within a tray. 
         [0052]    Trays may be configured of different colors. As a non-limiting example different color configurations enable identification/classification of items located within the trays. 
         [0053]    Trays may be fitted with integral LED lights for illuminating the interior of the trays or outside of the trays for illuminating the work space. 
         [0054]    Trays may be made from “glow-in-the-dark” material to provide light for illuminating the interior of the trays or for locating the trays in an otherwise dark environment. 
         [0055]    Coupling devices may be configured of a rod shaped in a half loop with ends of half loop connected via a latch. As a non-limiting example, latch may be configured as a spring-loaded closing hook. As a further non-limiting example, rod may have a diameter of ¼ of an inch. As a further non-limiting example, spring-loaded closing hook may be configured similar to that of a carabiner or swivel snap hook. 
         [0056]    Trays and couplings may be configured of a variety of materials and may be configured in a variety of sizes, shapes and colors. Furthermore, trays may be used for a variety of applications. Non-limiting examples for applications of trays include storage of plumbing and electrical components and tools. As a non-limiting example application, trays enable transport of tools and equipment into and through environments with a low vertical clearance environment. Non-limiting examples for users of trays include construction workers, auto mechanics, assembly workers, gardeners/nursery workers, harvesters, electronics installers, tailors, jewelers, artists and crafters. 
         [0057]    A lead may be attached to a loop for moving a tray or tray assembly. Furthermore, tray or tray assembly may be moved via application of a force to the attached lead. 
         [0058]    A tray or tray assembly may also be pushed along due to the inherent restricted lateral movement between connected trays. 
         [0059]      FIG. 1  illustrates an example tray device, in accordance with an embodiment of the present invention. 
         [0060]    A tray device  100  includes four lips with a sampling noted as a lip  102 , two raised corner lips with a sampling noted as a raised corner lip  104 , two non-raised corners with a sampling noted as a non-raised corner  105 , two loops with a sampling noted as a loop  106 , four sides with a sampling noted as a side  108 , a cavity  110 , a bottom  112  and two couplings with a sampling noted as a coupling  114 . 
         [0061]    Bottom  112  provides support and connects to side  108 . Raised corner lip  104  connects to the left end of side  108 . Non-raised corner  105  connects to the right end of side  108 . Loop  106  connects to a side and is located near the middle of the side. Coupling  114  connects to loop  106 . Cavity  110  is located above bottom  112  and interior to sides. 
         [0062]    Tray device  100  provides storage for items. Non-limiting examples of items include tools, components, parts and assemblies. Furthermore, tray device  100  may be used for transporting items associated with tray device  100 . 
         [0063]    Lip  102  enables stacking and securing a first tray device on top of second tray device. 
         [0064]    Raised corner lip  104  and non-raised corner  105  enable securely stacking a first inverted tray device on top of second tray device in order to provide a cover for the second tray device. 
         [0065]    Loop  106  enables connection of first tray device with a second tray device via a coupling. 
         [0066]    Side  108  provides a barrier to prevent displacement of items contained within tray device  100 . 
         [0067]    Cavity  110  provides a space for storing items. Non-limiting examples of items include tools, components, parts and assemblies. 
         [0068]    Coupling  114  provides connection from another tray device to tray device  100 . 
         [0069]      FIG. 1  illustrates an example tray device where a cavity provides a space for storage of items and a loop and a coupling enables connection of the tray device with other tray devices. 
         [0070]      FIG. 2A  illustrates an example tray device connected with a multiplicity of other tray devices to form a tray assembly, in accordance with an embodiment of the present invention. 
         [0071]    A tray assembly  200  includes tray device  100 , a tray device  202 , a tray device  204  and a tray device  206 . 
         [0072]    Tray devices  202 ,  204  and  206  are configured in a similar manner as tray device  100 . 
         [0073]    A lead device  208  connects to tray device  100  via coupling  114 . Tray device  202  connects to tray device  204  via a coupling  210 . Tray device  204  connects to tray device  206  via a coupling  212 . Tray device  206  connects to tray device  100  via a coupling  214 . 
         [0074]    Tray devices  100 ,  202 ,  204  and  206  enable storage of items. Furthermore, tray devices  100 ,  202 ,  204  and  206  enable transportation of items stored within the tray devices. Tray assembly  200  may be transported by application of a force to lead device  208 . Application of force to lead device  208  facilitates movement of tray device  100 . Furthermore, movement of tray device  100  applies a force to tray device  206  via coupling  214  resulting in movement of tray device  206 . Furthermore, movement tray device  206  applies a force to tray device  204  via coupling  212  resulting in movement of tray device  204 . Furthermore, movement of tray device  204  applies a force to tray device  202  via coupling  210  resulting in movement of tray device  202 . 
         [0075]    Tray assembly  200 , as configured in the illustration, enables transport for items contained within the trays when traversing tight spaces (e.g. crawl space, conduit, drain, etc.). Furthermore, tray assembly  200  may be transported in a straight line, in a curve, around obstacles and/or across uneven terrain. 
         [0076]    Tray assembly  200  may also be pushed via application of force to tray device  100  or tray device  202 . The configuration of the tray devices and associated couplings provides sufficient rigidity such that tray assembly  200  may be pushed. The distance between individual trays that is created by the combination of the size of the loops on the trays plus the coupling allow for train-style tracking when an assembly is pulled and also allows for adequate rigidity when an assembly is pushed. Typically, coupling length inside dimension may be roughly equal to the depth of tray dimension plus diameter of loop rod dimension and fabricated out of material such as, but not limited to, steel. 
         [0077]      FIG. 2A  illustrates an example tray device connected with a multiplicity of other tray devices to form a tray assembly where the tray assembly may be transported by application of a force to a lead device. 
         [0078]      FIG. 2B  illustrates an example tray device connected with a multiplicity of other tray devices to form a stacked tray assembly, in accordance with an embodiment of the present invention. 
         [0079]    Tray device  202  is oriented in an upright position and resides on the ground. Furthermore, tray device  204  is oriented in an upright position and is stacked onto tray device  202 . Tray device  206  is oriented in an upright position and is stacked onto tray device  204 . Tray device  100  is oriented in an upside down position and is inserted into tray device  206 . 
         [0080]    Tray assembly  200  may converted from the configuration as illustration in  FIG. 2A  to the stacked configuration as illustrated in  FIG. 2B  by folding tray device  100  over tray device  206  and inserting tray device  100  into tray device  206 . The partially stacked combination of tray device  100  and tray device  206  may then be rotated 180 degrees in a clockwise or counter clockwise manner and then inserted into tray device  204 . The partially stacked combination of tray device  100 ,  206  and  204  may then be rotated 180 degrees in a clockwise or counter clockwise manner and then inserted into tray device  202 . 
         [0081]    The stacked configuration enables economical storage of tray assembly  200 , as stacking of the devices reduces the space consumed by the assembly. 
         [0082]    The stacked configuration may be provided with any number means for conveying the assembly such as, but not limited to, simple straps or frames. 
         [0083]    Couplings may remain attached to trays whether the trays are stacked or inverted in order to provide a cover. 
         [0084]      FIG. 2B  illustrates an example tray device connected with a multiplicity of other tray devices to form a stacked tray assembly where one tray device is flipped over and inserted into an adjacent tray device, followed by rotation and insertion of the partially stacked tray devices into the remaining tray devices until the tray devices are configured in a stacked orientation. 
         [0085]      FIG. 3A  illustrates an example coupling for connecting tray devices where the coupling is closed, in accordance with an embodiment of the present invention. 
         [0086]    Coupling  114  as described with reference to  FIGS. 1-2  includes a left loop portion  302  and a right loop portion  304 . 
         [0087]    Coupling  114  enables trays to be connected by insertion of associated loops into coupling  114 . 
         [0088]    Left loop portion  302  connects to right loop portion  304  via a hinge portion  306 . 
         [0089]    Left loop portion  302  connects to right loop portion  304  via a latch portion  308 . 
         [0090]    Latch portion  308  may be configured of any know latching mechanism. As a non-limiting example, latch portion  308  may be configured as a spring latch. 
         [0091]    Latch portion  308  may be unlatched in order for left loop portion  302  and right loop portion to be separated at the top. 
         [0092]      FIG. 3A  illustrates an example coupling for connecting tray devices where a left loop connects to a right loop via a hinge and a latch, in accordance with an embodiment of the present invention. 
         [0093]      FIG. 3B  illustrates an example coupling for connecting tray devices where coupling is open, in accordance with an embodiment of the present invention. 
         [0094]    Latch portion  308  has been unlatched such that left loop portion  302  and right loop portion  304  are separated at the top forming an opening  310 . 
         [0095]    Opening  310  enables insertion and removal of loops associated with trays and loops associated with a lead into a space  312 . 
         [0096]    After loops have been inserted or removed, the loops may be connected at the top via latching of latch portion  308 . 
         [0097]      FIG. 3B  illustrates an example coupling for connecting tray devices where the coupling is open enabling insertion/deletion of loops, in accordance with an embodiment of the present invention. 
         [0098]    One skilled in the art will readily recognize the exemplary coupling described above is a simplistic embodiment.
