and above the lower level table 6, and the tabletops are stacked in
an inverted L-shaped arrangement such that the stacked table is
presented in a different spatial configuration.
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.

[0012] FIG. 7 is a drawing of the retracted stacked desk invention
herein, as viewed from the front.
[0013] FIG. 8 is an isometric drawing of the invention herein with
the upper level table and the lower level table set at a right
angle.
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.
