Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a sectional table, and more particularly, to a sectional table with gussets in which a table top and legs thereof can be easily assembled in a simple manner through a gusset mechanism.
2. Background of the Related Art
In general, a table is a general term of furniture for dining, serving, meeting, working, etc. It allows various goods or foodstuffs to be put thereon and helps a separate work to be efficiently conducted. Such a table is largely classified into two types of tables depending on the structure thereof, one being a fixed table in which table legs thereof are directly fixed to the underside of a table top thereof, and the other being a sectional table in which table legs thereof can be separated from and assembled with a table top thereof.
Recently, to achieve mass production and improvement of efficiency in assembling a table, a sectional table in which the table top and the table legs are assembled together by using various types of connecting members is more widely used, relatively to others. A gusset is one of the connecting members.
As shown in
FIG. 1
, a conventional sectional table with gussets is constructed in such a manner that gussets
6
are directly welded to a channel frame
4
that is secured to the lower surface of a table top
2
of the sectional table. In consequence, the table is simply assembled but is unstable structurally, such that the connected structure may be damaged due to a small impact, thereby revealing a limitation in fixing.
To solve the aforementioned problem, a worktable having an improved coupled structure between the channel frame and the gussets has been disclosed in U.S. Pat. No. 5,165,349. The worktable, as illustrated in
FIG. 2
, includes a table top
2
; an inverted hat-shaped channel frame
4
having openings
1
formed at the central portion thereof and flanges
3
formed at both ends thereof to be fixedly secured to the underside of the table top
2
; a back-up plate
5
secured by welds between upwardly extending opposite side portions of the channel frame
4
; gussets
6
at each leg location extending through the opening
1
in the channel frame
4
and upwardly inserted into the channel frame
4
to be fixedly secured to the channel frame
4
and the backup-plate
5
by welds; and table legs
7
secured to the underside of the table top
2
by the gussets by being inserted into the gussets
6
.
The worktable constructed as above has a drawback of making the construction and structure complicated since the gussets
6
are fixedly secured to the back-up plate
5
which, in turn, is secured to the channel frame
4
. Also the worktable has another drawback of deteriorating workability and efficiency in assembling since there are a great number of welded portions, such as those between the gussets and the back-up plate, the back-up plate and the channel frame, and the openings and the gussets.
Further, manufacturing costs, which accordingly increase, cannot be disregarded.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a sectional table with gussets that substantially obviates one or more problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a sectional table with gussets that can simplify work processes by improving the structure where gussets and a channel frame of the sectional table are assembled, and rigidly maintain the assembled state.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, there is provided a sectional table with gussets, including a table top; an inverted hat-shaped channel frame having cylindrical parts formed at the central portion thereof and flanges formed at both ends thereof, the cylindrical parts being formed through a deep-drawing process and the flanges being fixedly secured to the underside of the table top; cylindrical gussets inserted into the cylindrical parts of the channel frame at the upper end thereof to be fixedly secured to the cylindrical parts by welds; and table legs secured to the underside of the table top by the gussets by being inserted into openings of the gussets.
It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

Referring to
FIGS. 3
to
5
, a sectional table with gussets includes a table top
10
; an inverted hat-shaped channel frame
20
having cylindrical parts
22
formed at the central portion thereof and flanges
24
and
24
′ formed at both ends thereof, the cylindrical parts
22
being formed through a deep-drawing process and the flanges
24
and
24
′ being fixedly secured to the underside of the table top
10
; cylindrical gussets
30
inserted into the cylindrical parts
22
of the channel frame
20
at the upper end thereof to be fixedly secured to the cylindrical parts
22
by welds; and table legs
40
secured to the underside of the table top
10
by the gussets
30
by being inserted into openings of the gussets
30
.
The cylindrical parts
22
of the channel frame
20
may be modified depending on the size and shape of the gussets, and adhering members
26
are respectively provided on the upper surfaces of the flanges
24
and
24
′ to fixedly secure the flanges
24
and
24
′ to the underside of the table top
10
.
Adjusting screws
60
are respectively provided on circumferential surfaces of the gussets
30
to freely adjust the height of the table legs
40
at need.
In the meantime, cross-shaped openings of the upper ends of the cylindrical parts
22
serve to prevent the cylindrical parts from being deformed when welded portions
28
are tack-welded. A welding process needs to be done only on the portion in which the gussets
30
and the cylindrical parts
22
are in contact with each other, whereby the number of work processes and manufacturing costs are reduced.
FIGS.
6
(
a
) and
6
(
b
) are perspective views illustrating the state in which holders and the channel frame of the sectional table with gussets are assembled according to the present invention.
As shown in FIGS.
6
(
a
) and
6
(
b
), each of the holders
50
includes a plate
52
fixedly mounted on the inner surface of the table top
10
; and projections
54
and
54
′ projecting from the plate
52
and supported on the bottom surfaces of the flanges
24
and
24
′ of the channel frame
20
in such a manner that they are in close contact with the bottom surfaces thereof.
The holders
50
serve to easily fix the position of the channel frame
20
and also prevent the table top
10
and the channel frame
20
from being separated from each other even though the adhesive force of the adhering members
60
deteriorates. The holders
50
are mounted to be attachable and detachable in a simple fashion if necessary.
The projections
54
and
54
′ may be modified depending on the shape and size of the channel frame
20
.
As described above, the present invention has an advantage of simplifying the assembling process, if being compared with the conventional U.S. Pat. No. 5,165,349, since the connected state between the gussets and the channel frame can be rigidly maintained without a back-up plate. The present invention has another advantage of improving workability and efficiency in assembling since the welded portions are reduced in number to one, that is, the portion where the gussets and the cylindrical parts are in contact with each other.
As a result, the present invention has a further advantage in an economic aspect since the number of work processes and manufacturing costs are accordingly reduced.
Moreover, the present invention has still another advantage of easily fixing the position of the channel frame since the holders are employed, and preventing the table top from being separated from the channel frame even though the adhesive force of the adhering members decreases.
The forgoing embodiments are merely exemplary and are not to be construed as limiting the present invention. The present teachings can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
