Description:
BACKGROUND OF THE INVENTION  
       [0001]     1) Field of the Invention  
         [0002]     The invention herein relates to a stacked table assembly structure having extension and retraction capability to suit environmental space conditions or accommodate use by numerous persons.  
         [0003]     2) Description of the Prior Art  
         [0004]     Conventional table structures are fixed-dimension structures. Since such tables can only be placed next to each other, their physical size takes up considerable space, which inconveniences their arrangement, storage, and shipping. The said existent shortcomings of prior art table structures often cause user difficulties as substantiated above. As such, manufacturers are searching for breakthroughs in their production design.  
       SUMMARY OF THE INVENTION  
       [0005]     The primary objective of the invention herein is to provide a stacked table assembly structure in which since the table is in a stacked configuration, the tabletop area is not subject to space limitations, but can be adjustably extended and retracted to suit space availability, save space and, furthermore, facilitate shipping, the present invention is thus submitted as a new patent application.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0014]     Referring to  FIG. 3 , the structural drawing of the invention herein, the stacked table assembly structure of the present invention is comprised of components, including a main table  1 , primary leg rods  2 , an upper level table  3 , upper level table long leg rods  4 , upper level table short leg rods  5 , a lower level table  6 , lower level table long leg rods  7 , lower level table short leg rods  8 , anti-slip cushions  9 , and coaster wheels  10 , wherein:  
         [0015]     The main table  1  consists of a plurality of primary table legs  2  postured vertically on the floor for support and a minimum of two tables stacked under its tabletop.  
         [0016]     The upper level table  3 , as indicated in  FIG. 4 , must be a flat surface situated beneath the main table  1  tabletop and have a surface area that is smaller than that of the main table  1  top; long leg rods  4  and short leg rods  5  of different height are disposed below at the two sides of the said tabletop, with the short leg rods  5  stacked above the lower level table  6 ; anti-slip cushions  9  affixed to the bottom sections of the short leg rods  5  to maintain position such that the lower level table  6  cannot roll out; the long leg rods  4  at the other side are vertically situated on the floor for support, coaster wheels  10  are mounted on their bottom sections, and the height of the long leg rods  4  including the coaster wheels  10  must be equal to the stacked height of both the short legs rods  4  and the lower level table  6  such that its tabletop is horizontal and capable of outward and inward movement utilizing the coaster wheels  10  to thereby extend or retract.  
         [0017]     The lower level table  6 , as indicated in  FIG. 5 , must be a flat surface situated beneath the main table  1  tabletop and have a surface area that is smaller than that of the main table  1  tabletop, the upper level table  3  is horizontally stacked above the lower level horizontal table top; long leg rods  7  and short leg rods  8  of different height are disposed below at the two sides of the lower level table  6 , each vertically situated on the floor for support, with anti-slip cushions  9  affixed to the long leg rods  7  and coaster wheels  10  mounted on the short leg rods  8 ; and the height of the short leg rods  8  including the coaster wheels  10  must be equal to the height of the long leg rods  7  such that they are of an even stature and, furthermore, the lower level table  6  and the upper level table  3  above it are capable of coordinated movement outward and inward to thereby extend or retract.  
         [0018]     In another embodiment of the stacked table of the invention herein, referring to  FIG. 8 , the upper level table  3  rests on the short leg rods  5 , the upper level table  3  is perpendicular to and above the lower level table  6 , and the tabletops are stacked in an inverted L-shaped arrangement, with anti-slip cushions  9  affixed to the bottom sections of the short leg rods  5  such that the lower level table  6  does not roll out; the long leg rods  4  at the other side are vertically situated on the floor for support, coaster wheels  10  are mounted on the bottom sections of the long leg rods  4 , and the height of the long leg rods  4  including the coaster wheels  10  must be equal to the stacked height of both the short legs rods  4  and the lower level table  6  such that the stacked table is presented in a different spatial configuration.  
         [0019]     Referring to  FIG. 1  and  FIG. 2  of the invention herein,_when the said stacked table is placed in a room, the tabletops can be extended or retracted to suit environmental space conditions or accommodate use by numerous persons; referring to  FIG. 6  and  FIG. 7  of the invention herein, the anterior views of the stacked table illustrate that the present invention occupies less area and facilitates utilization such that it is not subject to the fixed size limitations of prior art tables.  
         [0020]     In summation of the foregoing section, since the invention here improves upon the existent shortcomings of the prior art due to its technological development limitations and effectively increases product utility, the present invention meets the patent application requirement of progressiveness and is submitted to the patent bureau for review and the granting of the commensurate patent rights.
