Description

【０００１】
【産業上の利用分野】
この発明は、テレビ台上でテレビ本体を回転させるテレビに関するものである。
【０００２】
【従来の技術】
図４は従来のテレビの回転機構を示した分解斜視図、図５はテレビ台上にテレビ本体を取付ける状態を示す断面図である。
図において、１はキャビネット、２はバックカバーで、これらでテレビ本体１０を構成する。３はテレビ本体底部に一体成形されたリブ、４はモーター駆動により回転する平外歯車４ａを有した回転装置、５はこの回転装置４をテレビ本体底部に取付けるためのネジである。６は周りに円筒型成形品であるすべりローラ７が複数配設されているリング、８はこのリング６が取付けられ、かつ平内歯車８ａが一体成形されているテレビ台である。そして、テレビ本体１０はテレビ台８上に軸９を中心に回転可能に取付けられ、かつ上記歯車４ａと８ａが互いにかみ合うように組立てられる。
【０００３】
次に動作について説明する。ネジ５によりテレビ本体の底部に取付けられた回転装置４の平外歯車４ａがモーター駆動により回転し、テレビ台８の平内歯車８ａとかみ合うことにより、キャビネット１，バックカバー２よりなるテレビ本体１０に回転力が生じる。この時、テレビ本体底部に成形されたリブ３が、リング６に取付けられたすべりローラ７の上をすべりながらころがることにより、テレビ本体は回転する。
【０００４】
【発明が解決しようとする課題】
従来の回転機構は以上のように構成されているので、図６に示すようにＣＲＴ１４の荷重により、キャビネット１の両端部に鎖線で示されるような変形δが発生するという問題点があった。特にワイドテレビの様に横長のＣＲＴでは、より大きなモーメントが加わり、大きな変形δが生じ易くなる。
【０００５】
この発明は上記のような問題点を解消するためになされたもので、キャビネットの変形を小さくして製品の信頼性を向上させるとともに、部品点数を少なくし、原価低減を図る事を目的とする。
【０００６】
【課題を解決するための手段】
この発明に係るテレビは、
テレビ台と、
テレビ台上に回転可能に載置されたテレビ本体と
を備え、
テレビ本体の底面に、テレビ本体の回転軸を中心とした平歯車がテレビ本体と一体成形され、
テレビ台の内側に、平歯車とかみ合う歯車を駆動する回転装置が設置され、
テレビ本体の底面に、テレビ本体の回転軸を中心とした所定の回転軌跡上に弧状のリブが形成され、
弧状のリブには、テレビ台上をすべりながら転がる複数のすべりローラが圧入され、
所定の回転軌跡は、テレビ本体内部において最も荷重がかかるテレビ本体の左右両側辺の近傍に位置し、かつ平歯車の径よりも大きくなるように構成したものである。
【０００７】
【作用】
この発明に係るテレビは、テレビ本体をすべらせるためのすべりローラをテレビ本体の回転軸に対し所定の回転軌跡上に配設し、テレビ本体内部において最も荷重がかかる部分の回転軌跡と回転軸方向に略一致するようにしたので、キャビネットの変形を防止する。
【０００８】
【実施例】
実施例１．
以下、この発明の一実施例を図について説明する。図１はテレビの回転機構を示した分解斜視図、図２はすべりローラの取付構造を示した部分拡大図、図３は取付状態を示す断面図である。
図において、従来技術と同一部分については同一符号で示すものとする。１０ａはテレビ本体１０の底部に一体成形された平外歯車で、キャビネット１とバックカバー２の底部にそれぞれ成形された平外歯車１ａ，２ｂからなり、これら平外歯車１ａ，２ａは一体に回転する。１１はテレビ本体１０の両側の端辺近くに形成された弧状のリブで、それぞれ複数のすべりローラ７を圧入している。１２はモーター駆動により回転する平外歯車１２ａを有した回転装置であり、平外歯車１２ａはモーターの駆動力をテレビに回転力として伝達する。１３はテレビを支えるテレビ台、５は回転装置１２をテレビ台１３に取付けるためのネジである。そしてテレビ本体１０はテレビ台１３上に軸９を中心に回転可能に取付けられ、かつ上記歯車１２ａと１０ａがかみ合うように組立てられる。
【０００９】
次に動作について説明する。ネジ５によりテレビ台１３の内側に取付けられた回転装置１２の平外歯車１２ａがモーター駆動により回転し、テレビ本体１０の底部に一体成形された平外歯車１０ａとかみ合うことにより、テレビ本体に回転力が生じる。この時、テレビ本体底部のリブ１１に圧入固定されたすべりローラ７がテレビ台１３の上面をすべりながら転がることにより、テレビ本体は回転する。
【００１０】
即ち、この発明によれば、テレビ荷重を支えテレビを転がすための円筒型成形品であるすべりローラ７が図１及び図３に示すようにテレビ本体１０の左右両側辺に近い所に位置しているために、テレビ荷重を両端で支え、図６に示されるようなテレビキャビネットの変形δが防止される。
又、従来必要であったリング６及びすべりローラ７のうち、リング６の機能はテレビ本体底部に一体成形されたリブ１１により発揮されるため、リング６が不要となり、結果として部品点数が減少する。
【００１１】
実施例２．
なお上記実施例では、キャビネット１とバックカバー２にわたって平外歯車、滑りローラ、リブを設けたものを図示したが、これらをキャビネット１側のみに構成してもよい。
【００１２】
【発明の効果】
以上のように、この発明に係るテレビは、テレビ台と、テレビ台上に回転可能に載置されたテレビ本体とを備え、テレビ本体の底面に、テレビ本体の回転軸を中心とした平歯車がテレビ本体と一体成形され、テレビ台の内側に、平歯車とかみ合う歯車を駆動する回転装置が設置され、テレビ本体の底面に、テレビ本体の回転軸を中心とした所定の回転軌跡上に弧状のリブが形成され、弧状のリブには、テレビ台上をすべりながら転がる複数のすべりローラが圧入され、所定の回転軌跡は、テレビ本体内部において最も荷重がかかるテレビ本体の左右両側辺の近傍に位置し、かつ平歯車の径よりも大きくなるようにしたので、キャビネットの変形を防ぐことができ、信頼性の高い製品が得られる。

A plurality of sliding rollers that roll while sliding on the TV stand are press-fitted into the arc-shaped rib,
The predetermined rotation trajectory is configured to be located in the vicinity of the left and right sides of the television main body where the load is most applied inside the television main body, and to be larger than the diameter of the spur gear .
[0007]
[Action]
In the television according to the present invention, a sliding roller for sliding the television main body is arranged on a predetermined rotation locus with respect to the rotation axis of the television main body, and the rotation locus and the rotation axis direction of the portion where the load is most applied inside the television body The cabinet is prevented from being deformed.
[0008]
【Example】
Example 1.
An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a rotating mechanism of a television, FIG. 2 is a partially enlarged view showing a sliding roller mounting structure, and FIG. 3 is a sectional view showing a mounting state.
In the figure, the same parts as those in the prior art are denoted by the same reference numerals. A flat external gear 10a is integrally formed on the bottom of the TV body 10, and is composed of flat external gears 1a and 2b formed on the bottom of the cabinet 1 and the back cover 2, respectively. These flat external gears 1a and 2a rotate together. To do. Reference numeral 11 denotes arc-shaped ribs formed near the edges on both sides of the television main body 10 and press-fit a plurality of sliding rollers 7 respectively. Reference numeral 12 denotes a rotating device having a plain external gear 12a that rotates by motor driving, and the plain external gear 12a transmits the driving force of the motor as a rotational force to the television. Reference numeral 13 denotes a TV stand for supporting the TV, and 5 denotes a screw for attaching the rotating device 12 to the TV stand 13. The TV main body 10 is mounted on the TV stand 13 so as to be rotatable about the shaft 9, and is assembled so that the gears 12a and 10a are engaged with each other.
[0009]
Next, the operation will be described. The flat external gear 12a of the rotating device 12 attached to the inside of the TV stand 13 by the screw 5 is rotated by a motor drive, and is engaged with the flat external gear 10a integrally formed on the bottom of the TV main body 10, thereby rotating to the TV main body. Power is generated. At this time, when the sliding roller 7 press-fitted and fixed to the rib 11 at the bottom of the TV main body rolls while sliding on the upper surface of the TV stand 13, the TV main body rotates.
[0010]
That is, according to the present invention, the sliding roller 7 which is a cylindrical molded product for supporting the television load and rolling the television is located near the left and right sides of the television body 10 as shown in FIGS. Therefore, the television load is supported at both ends, and the deformation δ of the television cabinet as shown in FIG. 6 is prevented.
Further, among the ring 6 and the sliding roller 7 that have been conventionally required, the function of the ring 6 is exhibited by the rib 11 integrally formed on the bottom of the TV main body. Therefore, the ring 6 becomes unnecessary, resulting in a reduction in the number of parts. .
[0011]
Example 2
In the above-described embodiment, a flat external gear, a sliding roller, and a rib are provided across the cabinet 1 and the back cover 2, but these may be configured only on the cabinet 1 side.
[0012]
【The invention's effect】
As described above , the television according to the present invention includes a television stand and a television main body that is rotatably mounted on the television stand, and a spur gear centered on the rotation axis of the television main body on the bottom surface of the television main body. Is integrally molded with the TV main body, and a rotating device is installed inside the TV stand to drive a gear that meshes with the spur gear. A plurality of sliding rollers that roll while sliding on the TV stand are press-fitted into the arc-shaped rib, and the predetermined rotation trajectory is in the vicinity of the left and right sides of the TV main body where the load is most applied inside the TV main body. Since it is positioned and larger than the diameter of the spur gear , the cabinet can be prevented from being deformed, and a highly reliable product can be obtained.
