TABLE STRUCTURE
FIELD OF THE INVENTION

The present invention relates to a table structure, and
more particularly to an inclination-adjusting structure to
facilitate the adjustment of the inclination and height of the
table plate.

BACKGROUND OF THE INVENTION

Generally speaking, the conventional
inclination-adjustable worktable includes adjusting rods
located under both sides of the table plate for adjusting the
inclination of the table plate. However, this worktable that
provides the simple and easy function for adjusting the

inclination has a complicated structure, and the adjusting rods,
which are protrudent from both sides of the worktable, are
unsafe.

SUMMARY OF THE INVENTION

It is a main object of the present invention to provide a
multi-stage inclination-adjusting structure, wherein a coupling
bracket is firmly mounted under a table plate for being coupled
with an arc-shaped, disk-shaped plate, whereby an angle of
inclination of the table plate is adjustable along the

arc-shaped, disk-shaped plate. If the required angle is
achieved, the positioning pillar is then inserted into a
positioning hole. The table plate is adjustable steplessly by
1


CA 02547042 2006-05-16

means of the arc-shaped coupling between the disk-shaped
plate and the coupling bracket such that the user is allowed to
make the stepless adjustment at any moment. For the
positioning purpose, the positioning pillar is then inserted into

the positioning hole. As a result, the present invention
provides the featured step- or stepless-adjustment.

It is another object of the present invention to provide
a structure that supports the weight of the table plate by a
single pillar of the support bracket. In addition, the present

invention further provides a power-saving, easily controllable
elevating structure, which is hidden in the support bracket, for
controlling the ascension and descension of the table plate. As
a result, the table plate can be ascended or descended easily
by merely controlling the control switches. Consequently, it is

timesaving, power-saving and convenient to make the
adjustment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1 through FIG. 3, a table structure
comprises a table plate 1, a coupling bracket 2, a disk-shaped

plate 3, a support bracket 4 and an elevating device 5,
wherein an inclination-adjusting structure for ascension and
descension of the table plate is composed of the coupling
bracket 2 and the disk-shaped plate 3.

The table plate 1 has a certain length on which several
pen-holding slots 11 are formed on both corners of a table
surface for holding pens or other articles to protect these
articles from fall when the table plate 1 is inclined.

The coupling bracket 2 is firmly mounted under the
table plate 1, and several slide chutes 21 are formed
longitudinally on the coupling bracket 2. Besides, several

positioning holes 22 are arranged in a row between two of the
slide chutes 21.

CA 02547042 2006-05-16

The disk-shaped plate 3 is mounted under the
coupling bracket 2, and the disk-shaped plate 3 has an
arc-shaped surface 31. Two slide ribs 32 are formed on the
arc-shaped surface 31 in the locations corresponding to the

slide chutes 21 of the coupling bracket 2. Besides, a
positioning pillar 35 is mounted on the arc-shaped surface 31
in the same direction as the positioning holes 22. A
flat-reception bracket 33 is mounted on a rearward of the
arc-shaped surface 31, and several through holes 34 are

formed penetrating the arc-shaped surface 31. The slide ribs
32 can be inserted into the slide chutes 21 if the coupling
bracket 2 is coupled with the disk-shaped plate 3, wherein
several lock plates 36 are further mounted on the slide ribs 32,
which are coupled with the slide chutes 21, for positioning the

slide ribs 32 in the slide chutes 21. In addition, the positioning
pillar 35 may be inserted into different positioning hole 22
such that the angle of inclination of the table plate 1 is
changeable by shifting the coupling bracket 2.

Referring again to FIG. 3, FIG. 5 and FIG. 7, the
support bracket 4, which is sufficient to support the weight of
table plate 1 is mounted under the disk-shaped plate 3,
wherein a holding bracket 43 having a positioning sleeve 431
on the center thereof is centrally mounted on the support
bracket 4. In addition, the elevating device 5 is held by the

positioning sleeve 431. The elevating device 5 is, for example,
a hydraulic elevator, a pneumatic elevator, an automatic
elevating device or other elevating structure.

CA 02547042 2006-05-16

Besides, a movable sleeve 41 consisting of an outer
sleeve 411 and an inner sleeve 413 is mounted in the holding
bracket 43. Two protrudent slides 412 are mounted
longitudinally, oppositely on an inner surface of the outer

sleeve 411 for being coupled with two recessed slides 414,
which are mounted oppositely on an outer surface of the inner
sleeve 413. The inner sleeve 413 is driven by the ascension or
descension of the elevating device 5 to perform the
corresponding movement since the disk-shaped plate 3 and

the inner sleeve 413 are coupled with each other by the lock
plates 36, which are locked to the top of the elevating device
5.

Referring to FIG. 2 through FIG. 4, FIG. 6 and FIG. 8,
the diagrams for explaining the adjustment of the inclination of
the table plate 1 are shown. In order to adjust the angle of

inclination of the table plate 1, the positioning pillar 35 is
driven by a first control switch 6 located under the table plate
1 to shrink into the disk-shaped plate 3, so that the positioning
pillar 35 is separated from the through hole 34 of the coupling

bracket 2, whereby the table plate 1 is shiftable along the
arc-shaped surface 31 by means of the coupling bracket 2.
When the table plate 1 is shifted, the slide ribs 32 are slidable
along the slide chutes 21 of the coupling bracket 2. When the
table plate 1 is inclined forward to a maxi-angle position, the

slide ribs 32 can be blocked by rear walls 211 of the slide
chutes 21. In addition, the angle of inclination of the table
plate 1 can be fixed securely by inserting the positioning pillar
5


CA 02547042 2006-05-16

35 into one of the positioning holes 22.

As shown in FIG. 2 and FIG. 8, when the table plate 1
is in horizontal plane, the flat-reception surface 23 of the
coupling bracket 2 is confined by the flat-reception bracket 33
to keep the table plate 1 horizontal.

Referring to FIG. 4 through FIG. 7, the elevating
structure for adjusting the height of the table plate 1 is shown.
The weight of the table plate is focused, supported by a single
pillar of the support bracket 4. In addition, the elevating

device 5 hidden in the support bracket 4 can be controlled by
a second control switch 7 mounted under the table plate 1. As
a result, the table structure can be operated easily by the user
since the first control switch 6 and the second control switch 7
are both mounted under the table plate 1. By controlling the

elevating device 5, the disk-shaped plate 3, the coupling
bracket 2 and the table plate 1 are driven for motions
simultaneously such that the inner sleeve 413, which is firmly
coupled with the elevating device 5, is allowed to slide along
the protrudent slides 412 of the outer sleeve 411, whereby the
height of the table plate 1 is adjustable.

Furthermore, a bookrack 8 is mounted on a rearward
of the table plate 1 to provide the user with the convenience in
placing books and articles.
