ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a television cabinet, and more particularly to a television cabinet of a structure which is divided into a front cabinet and a rear cabinet.
In a television cabinet of this kind, for example, if a front cabinet and a rear cabinet are aligned with each other, a bore portion of a boss provided on the front cabinet is coincident with a vis insertion hole provided on the rear cabinet, and if an attaching vis inserted from the back side into the vis insertion hole of the rear cabinet is screwed into the bore portion of the boss for the front cabinet and fastened, the front cabinet and the rear cabinet can be joined integrally via the attaching vis. One example of the front cabinet in such television cabinet as described in the Granted Japanese Utility Mode No. 3074025 is shown in FIG.
7
.
FIG. 7
is a front view of the front cabinet
10
for use in the television cabinet of video integral type, as seen from the back side,
FIG. 8
is an enlarged front view of A portion of
FIG. 7
,
FIG. 9
is a view of the A portion as seen from the direction of the arrow IX in
FIG. 8
, and
FIG. 10
is a cross-sectional view of the A portion, taken along the line X—X in FIG.
9
.
As seen from
FIGS. 7 and 8
, this front cabinet
10
is provided with a cylindrical boss
5
inside a ceiling board
12
of an outer board
11
, an attaching vis being screwed into this boss
5
. Reference numeral
13
denotes a cathode ray tube attaching boss, and reference numeral
14
denotes an opening in which a front face of the cathode ray tube is disposed. Also, a flexible strip
15
of U-character shape as seen from the front side is disposed inside the ceiling board
12
. Thereby, when the cathode ray tube, not shown, is attached in the cathode ray tube attaching bosses
13
, the cathode ray tube is prevented from directly abutting against the ceiling board
12
. If the cathode ray tube is contacted with this flexible strip
15
, the impact is relieved.
As shown in
FIG. 9
, the boss
5
is positioned at a rear end portion of the ceiling board
12
, and the flexible strip
15
is positioned at a front end portion of the ceiling board
12
. And the ceiling board
12
is provided with a platelike rib
17
extending lengthways, the flexible strip
15
being linked with a front end of the rib
17
. On the contrary, a rear end portion of the rib
17
is positioned at a side portion spaced a certain distance from the boss
5
. Also, the ceiling board
12
is linked with a plurality of platelike leg pieces
18
, a certain one of the leg pieces
18
being linked via a lateral plate
19
to the boss
5
, and the leg pieces
18
being linked to the rear end portion of the rib
17
. These leg pieces
18
serve to support the bosses
5
.
Further, the rib
17
has a high strength portion
21
of greater thickness extending lengthways, in which the high strength portion
21
is linked with an end portion of the boss
5
in a state with a certain clearance from the inner face of the ceiling board
12
, and a link portion
22
of the rib
17
with the ceiling board
12
is formed in smaller thickness over the entire length than the high strength portion
21
, as shown in
FIGS. 9 and 10
.
In this television cabinet, the front cabinet
10
is integrally moulded of synthetic resin. As seen from
FIG. 7
, the bosses
5
, the flexible strips
15
and the ribs
17
are disposed symmetrically on both end portions of the ceiling board
12
extending in the direction of the width, and none of the bosses
5
, the flexible strips
15
and the ribs
17
exist in the central part of the ceiling board
12
.
In this front cabinet
10
, the rib
17
serves as a ceiling board reinforcing rib to reinforce the ceiling board
12
, or as a boss reinforcing rib to reinforce the boss
5
. This rib
17
is formed at the substantially same height over its entire length.
In the conventional television cabinet as described above and shown in
FIGS. 7
to
10
, the ribs
17
are provided on both the left and right end portions of the ceiling board
12
for the front cabinet
10
in the direction of the width, and no ribs
17
exist in the central part of the ceiling board
12
, whereby the central part of the ceiling board
12
has a weaker strength than both the left and right end portions of the ceiling board
12
in the direction of the width. To resolve this problem, the flexible strip and the rib linked with the flexible strip may be also formed in the central part of the ceiling board
12
in the direction of the width to strengthen the central part of the ceiling board
12
. However, the bosses
5
, the flexible strips
15
and the ribs
17
exist on both the left and right end portions of the ceiling board
12
in the direction of the width, and further the flexible strip and the rib are present in the central part of the ceiling board
12
in the direction of the width, whereby the front cabinet
10
becomes a complex structure, with increased mould manufacturing costs.
The flexible strip may be positioned in the central part of the ceiling board
12
in the direction of the width, and linked with the rib by omitting the flexible strips on both the left and right end portions of the ceiling board
12
in the direction of the width to suppress the number of flexible strips. Thus, the complex structure of the front cabinet
10
is somewhat avoided, and the ceiling board
12
is strengthened.
However, since the rib
17
for reinforcing the boss
5
is formed at the substantially same height over its entire length, as described above, the strength of the rib
17
itself is decreased if the flexible strip
17
linked with the rib
17
is omitted, resulting in a risk that the rib
17
is broken due to vibration during the transportation, an impact caused by the collision or stacking load, impairing the action of reinforcing the ceiling board
12
. Though this problem can be resolved by increasing the thickness of the rib
17
, a phenomenon called “sink” arises on the outer surface of the ceiling board
12
, marring the appearance, when the rib
17
and the ceiling board
12
are integrally moulded, and in some cases, the front cabinet
10
itself may be judged as defective.
SUMMARY OF THE INVENTION
The present invention is achieved in the light of the aforementioned problems, and it is an object of the invention to provide a television cabinet wherein a flexible strip is positioned in the central part of a ceiling board in a direction of the width, and linked with a rib to reinforce the central part of the ceiling board in the direction of the width, and the bosses and the ribs for reinforcing the bosses are only disposed on the end portions of the ceiling board in the direction of the width by omitting the flexible strips from the end portions of the ceiling board in the direction of the width, whereby the complex structure of the cabinet is avoided without decreasing the strength of the ribs themselves for reinforcing the bosses, and there is no risk that the “sink” arises on the outer surface even by moulding the ceiling board.
A television cabinet of this invention comprises a front cabinet and a rear cabinet, wherein one of the front cabinet and the rear cabinet made of synthetic resin comprises a boss for screwing an attaching vis for joining the front cabinet and the rear cabinet, a platelike ceiling board reinforcing rib for reinforcing a ceiling board on one cabinet and a platelike boss reinforcing rib for reinforcing the boss and linked with the boss are moulded integrally on an inner face of the ceiling board in a longitudinally extending form, the boss reinforcing rib having a high strength portion of greater thickness extending lengthways, the high strength portion being spaced from the inner face of the ceiling board, and a link portion of the boss reinforcing rib with the ceiling board is formed in smaller thickness over its entire length than the high strength portion.
In this television cabinet, the ceiling board reinforcing rib serves to strengthen the ceiling board, a
