Description

本発明は、回転装置に関し、さらに詳しくは、液晶テレビなどの画面の角度を変更可能な回転装置に関するものである。   The present invention relates to a rotation device, and more particularly to a rotation device capable of changing the angle of a screen such as a liquid crystal television.

従来のこの種の回転装置としては、例えば、図７および図８に示すように、固定板５と、液晶テレビなどをその向きを変えるために回転させる回転板９とを備えた回転装置が知られている。   As a conventional rotating device of this type, for example, as shown in FIGS. 7 and 8, a rotating device including a fixed plate 5 and a rotating plate 9 for rotating a liquid crystal television or the like to change its orientation is known. It has been.

固定板５は、回転中心軸２とこの回転中心軸から離れた位置に配置された１つのボス４とを立設している。回転板９は、回転中心軸２に対する軸受け部６と、円弧状スリットよりなる開口部８とを有し、ボス４を開口部８に貫通させた状態で固定板５上に回転可能に設置されている。なお、ａは回転板９を固定板５上に固定するナット、ｂは同じくワッシャーである。   The fixed plate 5 is erected with the rotation center shaft 2 and one boss 4 arranged at a position away from the rotation center shaft. The rotating plate 9 has a bearing portion 6 for the rotation center shaft 2 and an opening portion 8 made of an arc-shaped slit, and is rotatably installed on the fixed plate 5 with the boss 4 passing through the opening portion 8. ing. Here, a is a nut for fixing the rotating plate 9 on the fixed plate 5, and b is a washer.

また、１４は、固定板５のゴム足であり、１５は、固定板５と回転板９との間に挿入される、回転摩擦を少なくする回転摩擦低減シートである。１６は、固定板５を覆い、天井部に開口部分１８を有し、回転板９に固定された覆い板である。１７は回転板９上に、覆い板１６の開口部分１８を介して固定され、液晶テレビなど（図示省略）を支持するためのスタンドネック、１９はそのカバーである。   Reference numeral 14 denotes a rubber foot of the fixed plate 5, and reference numeral 15 denotes a rotational friction reducing sheet that is inserted between the fixed plate 5 and the rotating plate 9 to reduce rotational friction. Reference numeral 16 denotes a cover plate that covers the fixed plate 5, has an opening 18 in the ceiling, and is fixed to the rotating plate 9. Reference numeral 17 is fixed on the rotating plate 9 through an opening 18 of the cover plate 16, and a stand neck for supporting a liquid crystal television or the like (not shown), and 19 is a cover thereof.

以上の構成の回転装置は、開口部８内をボス４が動く範囲内で回転板９を回転させることができる。
しかしながら、回転板９と固定板５はワッシャ―ｂを介してナットａで連結固定されているため、回転板９の回転力がワッシャ―ｂを通してナットａに伝わっていた。この回転方向がナットａを締める回転方向と逆方向の場合には、ナットａを緩めることになっていた。そのため、従来技術ではワッシャ―ｂを複数用いて回転力がナットａに伝わらないようにしていたが、回転操作の回数が多くなるとナットの緩みが生じていた。
更に、回転板９は、開口部８の一方の端部分にボス４が当たって回転が規制される（回転が停止される）際には、その衝撃を軸受け部６を介して回転中心軸２のみに伝えることになり、この衝撃がナットａの緩みのきっかけとなるばかりでなく、回転中心軸２の中心がズレたり、回転板にガタツキが生じるなどという問題もあった。 The rotating device configured as described above can rotate the rotating plate 9 within the opening 8 within the range in which the boss 4 moves.
However, since the rotary plate 9 and the fixed plate 5 are connected and fixed by the nut a through the washer b, the rotational force of the rotary plate 9 is transmitted to the nut a through the washer b. When the rotation direction is opposite to the rotation direction for tightening the nut a, the nut a is to be loosened. For this reason, in the prior art, a plurality of washers b are used so that the rotational force is not transmitted to the nut a. However, when the number of rotation operations increases, the nut loosens.
Further, when the rotation of the rotating plate 9 is restricted by the boss 4 hitting one end portion of the opening 8 (the rotation is stopped), the impact is applied to the rotation center shaft 2 via the bearing portion 6. This impact is not only the cause of the loosening of the nut a, but also the problem that the center of the rotation center shaft 2 is shifted and the rotation plate is rattled.

そこで、本発明の主要な目的の一つは、回転中心軸の中心のズレ、ナットの緩み、回転板のガタツキなどを防止することである。   Accordingly, one of the main objects of the present invention is to prevent misalignment of the center of the rotation center shaft, loosening of the nut, rattling of the rotating plate, and the like.

本発明は、回転中心軸と、この回転中心軸を中心に対向配置された２つの固定ボスとを立設した固定板と、
回転中心軸に対する軸受け部と、各固定ボスを貫通させるための２つの開口部とを有し、固定板上に回転可能に設置された回転板と、
各固定ボスに固定するための２つの固定部を有し、一方の固定部から他方の固定部に連結して延びる連結プレートと、
この連結プレートの２つの固定部を各開口部を介して対応する固定ボスに固定する固定手段と
を備えた回転装置を提供する。 The present invention comprises a fixed plate in which a rotation center axis and two fixed bosses arranged opposite to each other about the rotation center axis are erected,
A rotating plate having a bearing portion with respect to the rotation center axis and two openings for allowing each fixed boss to pass therethrough, and rotatably installed on the fixed plate;
A connecting plate having two fixing parts for fixing to each fixing boss and extending from one fixing part to the other fixing part;
There is provided a rotating device including fixing means for fixing two fixing portions of the connecting plate to corresponding fixing bosses through respective openings.

本発明は、別の観点によれば、回転中心軸と、この回転中心軸から離れた位置に配置された１つの固定ボスとを立設した固定板と、
回転中心軸に対する軸受け部と、固定ボスを貫通させるための開口部とを有し、固定板上に回転可能に設置された回転板と、
回転中心軸に嵌合させるための嵌合部と、固定ボスに固定するための固定部とを有し、この固定部から嵌合部に連結して延びる連結プレートと、
この連結プレートの固定部を、嵌合部を回転中心軸に嵌合させ軸受け部を押さえた状態で、開口部を介して固定ボスに固定する固定手段と
を備えた回転装置を提供できる。 According to another aspect of the present invention, there is provided a fixed plate in which a rotation center axis and one fixed boss arranged at a position away from the rotation center axis are erected,
A rotating plate having a bearing portion with respect to the rotation center shaft and an opening for penetrating the fixed boss, and rotatably installed on the fixed plate;
A connecting plate for fitting to the rotation center shaft, a fixing portion for fixing to the fixing boss, and a connecting plate extending from the fixing portion to the fitting portion;
There can be provided a rotating device including fixing means for fixing the connecting plate fixing portion to the fixing boss through the opening in a state where the fitting portion is fitted to the rotation center shaft and the bearing portion is pressed.

本発明に係る回転装置によれば、少なくとも一端を固定ボスに固定し、他端を固定ボスまたは回転中心軸に固定するための２つの固定部を有する連結プレートと、この連結プレートの固定部を回転板の開口部を介して固定ボスに固定する固定手段とによって固定板と回転板を連結固定するようにしたため、回転板の回転力により緩む部品がなくなる。
更に、開口部の端部分が固定ボスに当たって回転を停止する際に、その衝撃力を、回転板自体だけではなく連結プレートを介して、回転中心軸に分散して伝えることができるようになり、固定ボスへの衝撃力を弱めることができる。 According to the rotating device of the present invention, at least one end is fixed to the fixed boss, and the other end is fixed to the fixed boss or the rotation center shaft. Since the fixing plate and the rotating plate are connected and fixed by the fixing means fixed to the fixing boss through the opening of the rotating plate, there is no part loosened by the rotational force of the rotating plate.
Furthermore, when the end portion of the opening hits the fixed boss and stops rotating, the impact force can be distributed and transmitted to the rotation center axis not only through the rotating plate itself but also through the connecting plate, The impact force on the fixed boss can be weakened.

本発明は、少なくとも１つの固定ボスに固定するための固定部を有する連結プレートと、この連結プレートの固定部を、軸受け部を押さえた状態で、開口部を介して対応する固定ボスに固定する固定手段とを備えた点を特徴とする。
ここで、連結プレートが、２つの固定部と回転中心軸に嵌合させる嵌合部とを有し、固定手段が、連結プレートの２つの固定部を、嵌合部を回転中心軸に嵌合させた状態で、対応する固定ボスに固定するよう構成し、回転中心軸の中心のズレ、ナットの緩み、回転板のガタツキなどをより確実に防止できるようにしてもよい。 The present invention fixes a connecting plate having a fixing portion for fixing to at least one fixing boss, and the fixing portion of the connecting plate to the corresponding fixing boss through the opening while holding the bearing portion. It is characterized by having a fixing means.
Here, the connecting plate has two fixing portions and a fitting portion to be fitted to the rotation center shaft, and the fixing means fits the two fixing portions of the connecting plate to the fitting portion on the rotation center shaft. In such a state, it may be configured to be fixed to the corresponding fixed boss so as to prevent misalignment of the center of the rotation center shaft, loosening of the nut, rattling of the rotating plate, and the like.

本発明において、回転板の開口部は、円弧状スリット部からなり、その両端部分で回転板の回転角度を所定の値（例えば、１８０度以内）に規制するよう構成し、液晶テレビなどを安定して回転できるようにしてもよい。   In the present invention, the opening of the rotating plate is formed of an arc-shaped slit, and the rotation angle of the rotating plate is regulated to a predetermined value (for example, within 180 degrees) at both ends thereof, thereby stabilizing the liquid crystal television or the like. And may be rotated.

連結プレートの固定部を固定ボスに固定する固定手段としては、特に限定されないが、ネジ、ボルトまたはナットを好ましいものとして挙げることができ、もちろん、これに対応して固定ボスにはネジ孔またはネジ軸が必要であり、固定部をそれらのネジ、ボルト、ネジ軸を通し、連結プレートを固定できる孔部とする必要がある。
また、固定板と回転板との間には、両板間の摩擦を少なくする摩擦低減シートをさらに備えてもよい。 A fixing means for fixing the fixing portion of the connecting plate to the fixing boss is not particularly limited, but a screw, a bolt or a nut can be mentioned as a preferable one. Of course, the fixing boss has a screw hole or a screw corresponding thereto. A shaft is required, and the fixing portion needs to be a hole through which those screws, bolts, and screw shafts can pass to fix the connecting plate.
Further, a friction reducing sheet that reduces friction between the two plates may be further provided between the fixed plate and the rotating plate.

本発明は、さらに別の観点によれば、上述した回転装置と、ディスプレイと、このディスプレイを回転装置の回転板に固定するディスプレイ固定手段とを備えたディスプレイ装置を提供できる。
ここで、ディスプレイは、液晶ディスプレイ、プラズマディスプレイなどの平面ディスプレイであってもよい。 According to still another aspect, the present invention can provide a display device including the rotating device described above, a display, and display fixing means for fixing the display to a rotating plate of the rotating device.
Here, the display may be a flat display such as a liquid crystal display or a plasma display.

The display fixing means comprises a stand neck 17 and 19 is the stand neck cover. Reference numeral 16 denotes a cover plate that covers the fixed plate 5 and the connecting plate 11, has an opening 18 in the ceiling, and is fixed to the rotating plate 9.

固定板５は、回転中心軸２と、この回転中心軸を中心に対向配置された２つの固定ボス３，４とを立設し、底面にはゴム足１４を備えている。
回転板９は、回転中心軸２に対する軸受け部６と、各固定ボス３，４を貫通させるための２つの開口部としての円弧状スリット７，８とを有し、固定板５上に、２つのスリット７，８と各固定ボス３，４との相対移動範囲内で回転可能に設置されている（スリット７，８と各固定ボス３，４とは、回転板９の回転に対し相互にストッパーとなる）。

The rotating plate 9 has a bearing portion 6 with respect to the rotation center shaft 2 and arc-shaped slits 7 and 8 as two openings for allowing the fixed bosses 3 and 4 to pass through. The slits 7 and 8 and the fixed bosses 3 and 4 are installed so as to be rotatable within a relative movement range (the slits 7 and 8 and the fixed bosses 3 and 4 are mutually connected to the rotation of the rotating plate 9. It becomes a stopper).
Reference numeral 15 denotes a rotational friction reducing sheet that is inserted between the fixed plate 5 and the rotating plate 9 to reduce rotational friction.

さて、連結プレート１１は、固定ボス３，４に固定するための２つの固定部（連結プレート１１両端の孔部）を有し、一方の固定部から他方の固定部に連結して延びる。

次に、以上の構成を備えた回転装置の作動を簡単に説明する。
平面ディスプレイＨを所定の角度以上に回転させようとすると、スタンドネック１７を介して、回転板９が回転し、その円弧状スリット７，８の各端部分が固定板５の固定ボス３，４に当接（衝突）して平面ディスプレイＨが停止する。この際、平面ディスプレイＨ、スタンドネック１７、回転板９などは、全体としてきわめて大きな重量なので、当接の衝撃力はきわめて大きい。しかし、その衝撃力（トルク）は、回転板９だけではなく、連結プレート１１を介して、回転中心軸２に分散して伝えることができ、それによって衝撃力を弱め、回転中心軸２の中心のズレ、ナットの緩み、回転板９のガタツキなどを防止できる。

The flat display H stops. At this time, since the flat display H, the stand neck 17, the rotating plate 9 and the like are extremely heavy as a whole, the contact impact force is extremely large. However, the impact force (torque) can be distributed and transmitted not only to the rotating plate 9 but also to the rotation center shaft 2 via the connecting plate 11, thereby reducing the impact force and reducing the center of the rotation center shaft 2. It is possible to prevent misalignment, loosening of nuts, rattling of the rotating plate 9, and the like.
Further, since the fixed boss is supported by the fixed plate 9 and the connecting plate 11, damage to the fixed boss can be suppressed as compared with the conventional case where only the fixed plate 9 is supported.

It mainly consists of a rotation device (rotation table) for supporting the flat display and a fixing means for fixing the flat display to the rotation device.

この回転装置は、図５および６において、固定板５と、回転板９と、連結プレート２１と、固定手段としてのネジ１３とから主としてなる。
ディスプレイ固定手段はスタンドネック１７からなり、１９はそのスタンドネックカバーである。なお、１６は、固定板５と、連結プレート２１とを覆い、天井部に開口部分１８を有し、回転板９に固定された覆い板である。 5 and 6, the rotating device mainly includes a fixed plate 5, a rotating plate 9, a connecting plate 21, and screws 13 as fixing means.

回転板９は、回転中心軸２に対する軸受け部６と、固定ボス４を貫通させるための開口部としての円弧状スリット８とを有し、固定板５上に、スリット８と固定ボス４との相対移動範囲内で回転可能に設置されている。
なお、１５は固定板５と回転板９との間に挿入される、回転摩擦を少なくする回転摩擦低減シートである。 The fixed plate 5 is provided with a rotation center shaft 2 and a fixed boss 4 disposed at a position away from the rotation center axis, and is provided with rubber feet 14 on the bottom surface.
The rotating plate 9 has a bearing portion 6 with respect to the rotation center shaft 2 and an arc-shaped slit 8 as an opening for allowing the fixed boss 4 to pass through.

次に、以上の構成を備えた回転装置の作動を簡単に説明する。
平面ディスプレイを所定の角度以上に回転させようとすると、スタンドネック１７を介して、回転板９が回転し、その円弧状スリット８の端部分が固定板５の固定ボス４に当接（衝突）して平面ディスプレイが停止する。 Next, the operation of the rotating device having the above configuration will be briefly described.
When the flat display is rotated more than a predetermined angle, the rotating plate 9 is rotated via the stand neck 17, and the end portion of the arc-shaped slit 8 comes into contact (collision) with the fixed boss 4 of the fixed plate 5. The flat display stops.

この際、平面ディスプレイ、スタンドネック１７、回転板９などは、全体としてきわめて大きな重量なので、当接の衝撃力はきわめて大きい。しかし、その衝撃力は、回転板９だけではなく、連結プレート２１を介して、回転中心軸２に分散して伝えることができ、それによって衝撃力を弱め、回転中心軸２の中心のズレ、ナットの緩み、回転板９のガタツキなどを防止できる。
また、固定ボスを固定板９と連結プレート１１で支えるため、固定板９のみで支えていた従来に比べて、固定ボスの破損を抑えることができる。 At this time, since the flat display, the stand neck 17, the rotating plate 9 and the like are extremely heavy as a whole, the contact impact force is extremely large. However, the impact force can be distributed and transmitted not only to the rotating plate 9 but also to the rotation center shaft 2 via the connection plate 21, thereby weakening the impact force and shifting the center of the rotation center shaft 2, It is possible to prevent loosening of the nut, rattling of the rotating plate 9 and the like.
Further, since the fixed boss is supported by the fixed plate 9 and the connecting plate 11, damage to the fixed boss can be suppressed as compared with the conventional case where only the fixed plate 9 is supported.
