with reference now to the drawings , and in particular to fig1 to 8 thereof , a new and improved portable tray apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described . fig1 illustrates a prior art tray apparatus 1 wherein a compartmentalized tray structure includes a cavity 3 directed between the side wall of the tray structure to permit an individual to grasp a cup receiving member 4 that projects through a bottom surface of the tray structure . more specifically , the portable tray apparatus 10 of the instant invention essentially comprises a first rigid base plate 11 hingedly mounted to a second rigid base plate 12 . a plurality of hinge members 13 hingedly mount the first and second base plates together at the forward edges 18 and 19 respectively o the first and second base plates 11 and 12 . the base plates 11 and 12 are of a generally rectangular configuration and are of a mirror image construction relative to one another and each include a respective first and second elongate storage recess 20 and 21 arranged parallel to and adjacent the respective first and second base plate forward edges 18 and 19 . the abutment of the first and second base plate forward edges 18 and 19 define a first and second base plate interface 17 in a coextensive relationship of the first and second forward edges 18 and 19 relative to one another . reference to fig4 illustrates use of parallel recess grooves 15 that extend in longitudinal alignment from the bottom surface of the first and second base plates with a locking bar 16 slidably arranged within each groove 15 that is positionable within the groove 15 within the bottom surface of the first base plate and slidable to overlie the interface 17 to thereby fixedly latch the first and second base plates 11 and 12 together when in an extended configuration as illustrated in fig2 and 3 for example . each top surface of each portable tray includes plural pairs of receiving apertures 22 positioned adjacent the left sides 18c and 19c respectively of the first and second base plates . a second pair of receiving apertures 23 are positioned adjacent the right sides 18b and 19b of the receiving apertures with a third pair of receiving apertures 24 positioned medially of the first and second pair of receiving apertures . a fourth pair of receiving apertures 25 are positioned adjacent the elongate storage recess 20 and 21 respectively of each of the first and second base plates with a fifth pair of receiving apertures 26 positioned adjacent the rear terminal edge 18a and 19a respectively of the first and second base plates . the respective first through fifth pairs of receiving apertures receive a respective first through fifth pair of support rods 28 through 32 in a manner as illustrated in fig2 and 6 for example . each lower terminal end of each support rod is complementarily received within a respective aperture . each upper terminal end of each rod pair is arranged to receive a socket end of an associated u - shaped cap rod . for example a first through fifth cap rod 33 through 37 inclusively is mounted on a respective first through fifth pairs of support rods 28 through 32 respectively . the first cap rod includes first cap rod socket ends 33a , the second cap rod includes second cap rod socket ends 34a , the third cap rod 35 includes third cap rod socket ends 35a , the fourth u - shaped cap rod 36 includes fourth cap rod socket ends 36a and the fifth u - shaped cap rod 37 includes fifth cap rod socket ends 37a with each socket end complementarily receiving an upper terminal end of an associated support rod . when assembled , a plural pair of cup receiving cavities are defined for mounting of a drinking cup and the like therewithin . a support surface between the fourth rod pair and cap rods is provided for the mounting and transport of various food components thereon such as during a sporting event and the like to support the food components from a concession stand to a seating area for example . an alternative manner of constructing the support rods and cap rods may include the forming of a respective cap rod and support rod pair as a unitary construction with the rod members of each rod pair inter - folded relative to respective cap rod . during storage of the organization in a manner as illustrated in fig7 the support rods and respective cap rods are disassembled and positioned within the respective receiving recesses defined by the first and second elongate storage recesses 20 and 21 . thereafter , the organization may be inter - folded in a manner as illustrated in fig8 . it may be desired to utilize securement straps such as flexible securement straps 38 that are mounted adjacent the first base plate rear terminal edge 18a with a first hook and loop fastener surface 39 for securement to mounting straps 40 that are mounted to the bottom surface of the second base plate 12 adjacent the second base plate upper terminal edge 19a as illustrated in fig7 . the mounting straps 40 will include a second hook and loop fastener surface to permit securement of the flexible securement strap 38 to the mounting straps 40 in a manner as illustrated in fig8 for transport of the organization as a compact unitary structure as illustrated . as to the manner of usage and operation of the instant invention , the same should be apparent from the above disclosure and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided . with respect to the above description then , it is to be realized that the optimum dimensional relationships for the parts of the invention , to include variations in size , materials , shape , form , function and manner of operation , assembly and use , are deemed readily apparent and obvious to one skilled in the art , and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention . therefore , the foregoing is considered as illustrative only of the principles of the invention . further , since numerous modifications and changes will readily occur to those skilled in the art , it is not desired to limit the invention to the exact construction and operation shown and described , and accordingly , all suitable modifications and equivalents may be resorted to , falling within the scope of the invention .
the apparatus sets forth a tray organization that is usable wherein first and second rigid base members are hingedly mounted relative to one another with plural pairs of apertures mounted on each top surface of each base plate to receive plural pairs of support rods wherein the support rods are joined at their upper ends by a spanning u - shaped cap member . the rods and cap members are separable and are receivable within recesses formed within each base plate to secure the rods and cap members within the base plates during periods of non - use during transport and storage of the organization .
