Description

【0001】
【発明の属する技術分野】
この発明は、薄型表示装置用スタンドに関し、特に、表示パネルの高さ位置の調節が可能であり、かつ、画面の縦横の切り替えが可能な薄型表示装置に用いるスタンドに関する。
【0002】
【従来の技術】
従来より、表示パネルの高さ位置の調節が可能であり、かつ、画面の縦横の切り替えが可能な薄型表示装置がある。この種の従来の薄型表示装置は、表示パネルを昇降可能にかつ所望の位置で停止可能に支持する高さ調整機構、および画面の縦横の切り替えを行うために表示パネルを90°回転させるローテーション機構を備えているが、従来の薄型表示装置用スタンドでは、前記高さ調整機構およびローテーション機構がそれぞれ独立した機構として設けられている。
【0003】
そして、画面の縦横の切り替えを行う時は、表示パネルを上昇させ、その高い位置で表示パネルを90°回転させて、画面を横長から縦長にあるいは縦長から横長に切り替える。そして、縦長で用いるときは、表示パネルを高い位置の近傍に保持し、横長で用いるときは、通常、横長に切り替えの後、画面を見易くするために、表示パネルを低い位置に下降させる。
【0004】
【発明が解決しようとする課題】
上記従来の薄型表示装置用スタンドにおいて、表示パネルがあまり高くない位置にある時に、画面の縦横の切り替え動作すなわち表示パネルを回転させるローテーション動作を行うと、通常、表示パネルの対角線の角部が机上面等の載置面に当たってしまう。表示パネルに無用な衝撃を与えることは好ましくないので、そのような誤操作が生じないように、表示パネルが低い位置にある時には回転できないように制限されていることが好ましい。
【0005】
本発明は上記事情に鑑みてなされたもので、表示パネルが高い位置にある時は自由にローテーション動作を行うことができ、低い位置にある時には自動的にローテーション動作が制限される薄型表示装置用スタンドを提供することを目的とする。
【0006】
【課題を解決するための手段】
上記課題を解決する本発明の薄型表示装置用スタンドは、スタンドのベースとなる第1のスタンド部材と、この第1のスタンド部材に垂直にかつ上下動可能に設けられた垂直軸と、この垂直軸を常時上向きに付勢するばねと、この垂直軸の上昇限を規定する上昇限規定手段と、前記第1のスタンド部材に昇降可能に設けられた第2のスタンド部材と、表示パネル画面中心位置で画面と直交する向きの軸心を持ち前記第2のスタンド部材に前記線軸心回りに回転可能に設けられたパネル支持軸とを備え、
前記垂直軸の上端に、直立する半円板状のストッパを一体に設け、前記パネル支持軸の表示パネル側と反対側の端部に、前記垂直軸の上端のストッパの外周部が嵌入可能な直角二方向の2つの円弧状の係合溝を持つ係合部を設けたことを特徴とする。
【0007】
請求項2は、請求項1の薄型表示装置用スタンドにおいて、表示パネルのチルト動作のために前記パネル支持軸を第2のスタンド部材に横向きの水平なヒンジ軸を中心として上下に回動可能に設けるとともに、前記垂直軸の上端のストッパの外周部に波状凹凸を形成し、前記係合部の2つの係合溝に前記波状凹凸と噛み合う波状凹凸を形成したことを特徴とする。
【0008】
【発明の実施の形態】
以下、本発明の実施の形態を図1〜図7に示した一実施例を参照して説明する。図1は本発明の一実施例の薄型表示装置用スタンド3の一部切り欠き斜視図、図2は図1のA−A断面図である。これらの図において、1は薄型表示装置用スタンド3のベースとなる第1のスタンド部材で、この第1のスタンド部材1に第2のスタンド部材2が昇降可能に設けられている。第1のスタンド部材1および第2のスタンド部材2はいずれもボックス状をなしており、第2のスタンド部材2は第1のスタンド部材1の外周に嵌合して上下に摺動可能である。なお、第2のスタンド部材2は、図示略のラッチ機構等により所望の高さ位置に停止させることが可能である。すなわち、高さ調整機構を備えている。
【0009】
前記第1のスタンド部材1の中央に垂直軸4が垂直にかつ上下動可能に設けられている。この垂直軸4は中間部に鍔5を固定しており、この鍔5を介してばね6により上向きに付勢されている。また、前記第1のスタンド部材1の側壁から水平に延出させた高さ規制板7を貫通するとともに、前記鍔5がこの高さ規制板7に当たることで、上昇限を規定されている。前記鍔5および高さ規制板7は垂直軸4の上昇限を規定する上昇限規定手段8を構成する。
【0010】
10は図示略の表示パネルを取り付ける表示パネル取付板であり、この表示パネル取付板10の中央にパネル支持軸12が垂直に固定されている。パネル支持軸12の軸心は、表示パネル画面中心位置で画面と直交する向きをなしている。このパネル支持軸12は、保持枠13の前板部13aに矢印aのように軸心回りに回転可能に支持されている。このパネル支持軸12の矢印a方向の回転が、画面の縦横の切り替え動作、すなわち表示パネルを回転させるローテーション動作である。
前記保持枠13の左右の側板部13bは、第2のスタンド部材2の上面部に固定された対向する左右一対のL型部材14にヒンジ軸15で回転可能に取り付けられ、これによりパネル支持軸12および保持枠13がヒンジ軸15を中心として上下に回動可能である。前記、表示パネル取付板10、保持枠13、L型部材14は金属板製である。
図示は省略するが、パネル支持軸12は、ヒンジ軸15を中心とする回転動作における任意に傾き角で停止させることができるようになっており、このパネル支持軸12のヒンジ軸15を中心とする回転動作が、表示パネルの上下の傾き角を変えるチルト動作である。
【0011】
前記垂直軸4の上端には、図4(イ)、(ロ)にも示すように、直立する半円板状のストッパ18が一体に設けられている。一方、前記パネル支持軸12の表示パネル取付板10と反対側の端部に前記ストッパ18と係合可能な係合部20を有し、この係合部20は、図3に拡大して示すように、前記垂直軸4の上端のストッパ18の外周部が嵌入可能な円弧状の係合溝19を2つ有している。この2つの係合溝19は互いに直角をなす位置にあり、パネル支持軸12の直角二方向の2つの回転位置、すなわち表示パネルの縦横の2つの位置に対応している。そして、前記ストッパ18の外周部および前記係合溝19には、互いに噛み合う波状凹凸18a、19aを形成している。
【0012】
上記の薄型表示装置用スタンド3において、図示略の表示パネルを手で昇降させると、パネル支持板10、パネル支持軸12、保持枠13、L型部材14、第2のスタンド部材2等が一体となって第1のスタンド部材1に対して昇降する。図1、図2あるいは図4は、表示パネルが使用時の高さ位置でなくローテーション動作を行う高さ位置にある。この状態では、垂直軸4は、鍔5が高さ規制板7に当たって上昇限位置に止まっているので、パネル支持軸12の端部の係合部20は垂直軸4の上端のストッパ18から離間している。したがって、パネル支持軸12は制限を受けずに自由に回転できる。すなわち、この状態では、表示パネルおよびパネル支持軸12を回転させても、表示パネルの対角線の角部が机上面等の載置面に当たることはなく、画面の縦横の切り替えを自由に行うことができる。
なお、この状態では、パネル支持軸12をヒンジ軸15を中心として上下方向に回転させる動作は、パネル支持軸12の係合部20がストッパ18から離れているので、波状凹凸19a、18aどうしの噛み合いの抵抗がない軽い感触で行われる。
【0013】
図4(イ)、(ロ)の状態にあるパネル支持軸12を表示パネルとともに下降させると、図5(イ)、(ロ)に示すように、パネル支持軸12の端部の係合部20の一方の係合溝19に垂直軸4のストッパ18が嵌入する。これにより、パネル支持軸12のその軸心回りの回転は制限され、したがって、画面の縦横の切り替え動作すなわち表示パネルをパネル支持軸12の軸心回りに回転させるローテーション動作は制限される。したがって、誤って表示パネルのローテーション動作を行って、表示パネルの対角線の角部が机上面等の載置面に当たるという問題は発生しない。
【0014】
この場合、係合部20の係合溝19と垂直軸4のストッパ18とは波状凹凸19a、18aで互いに噛み合っているので、図6に示すように表示パネルのチルト動作のためにパネル支持軸12をヒンジ軸15を中心として上下方向に回転させた時、係合部20が垂直軸4をばね6の反力に打ち勝って押し下げることで、波状凹凸18a、19aのピッチ毎に回転できる。すなわち、表示パネルの上下方向の回転は、波状凹凸18a、19aのピッチの間隔で固定されるいわゆるクリック機構として行われ、パネル支持軸12をヒンジ軸15を中心として回転させるチルト動作におけるパネル支持軸12の傾き角、すなわち表示パネルの傾き角を安定して保持することができる。
【0015】
パネル支持軸12の端部の係合部20が垂直軸4の上端のストッパ18に係合した状態で、表示パネルおよびパネル支持軸12を下降させると、係合したまま、垂直軸4をばね6の反力に打ち勝って押し下げる。したがって、依然として、ローテーション動作を制限することができる。
【0016】
図5(イ)、(ロ)の状態から画面の切り替えを行う時は、パネル支持軸12を図4(イ)、(ロ)のような高さ位置に一旦上昇させ、垂直軸4のストッパ18とパネル支持軸12の係合部20との係合を解除する。そして、前述したように表示パネルおよびパネル支持軸12を90°回転させ、次いで下降させてパネル支持軸12の係合部20と垂直軸4のストッパ18とを係合させると、図7(イ)、(ロ)の状態となる。すなわち画面が図5の縦長または横長の使用状態から図7の横長または縦長の使用状態に切り替わる。ただし、縦長および横長のいずれの場合でも、図4のような高さ位置で用いることは当然可能である。
【0017】
表示パネルのローテーション動作を行えない高さ位置(図5や図7の高さ位置)では、チルト動作を試みると、そのチルト動作の感触でストッパと係合溝とが波状凹凸で噛み合っていることが直ちに分かるので、ローテーション動作ができない位置であると直ちに認識することができる。
【0018】
なお、第1のスタンド部材1および第2のスタンド部材2の構造は、任意であり、実施例のようなボックス状でなくてもよい。また、垂直軸4の高さを規制する上昇限規制手段8、パネル支持軸12を軸心回りに回転可能に支持する構造等も実施例のものに限らず、種々設計変更することができる。
【0019】
【発明の効果】
本発明によれば、表示パネルの高さ調整機構とローテーション機構とが関連付けられており、表示パネルが低い位置にある時には自動的にローテーション動作が制限されるので、表示パネルを低い位置で回転させて表示パネルの角部を載置面にぶつけてしまうという誤操作を防止することができ、表示パネルに無用な衝撃を与えるおそれがなくなるという効果が得られる。
【0020】
また、請求項2によれば、垂直軸のストッパとパネル支持軸の端部の係合溝とが波状凹凸で噛み合うので、表示パネルのチルト動作に対していわばクリック機構の働きをし、表示パネルの傾き角を安定して保持することができるという効果が得られる。また、表示パネルのローテーション動作を行えない高さ位置では、チルト動作を試みると、そのチルト動作の感触でストッパと係合溝とが波状凹凸で噛み合っていることが直ちに分かるので、ローテーション動作ができない位置であると直ちに認識することができる、という効果も得られる。

[0002]
[Prior art]
2. Description of the Related Art Conventionally, there are thin display devices that can adjust the height position of a display panel and can switch the screen between vertical and horizontal directions. This type of conventional thin display device includes a height adjustment mechanism that supports the display panel so that the display panel can be moved up and down and can be stopped at a desired position, and a rotation mechanism that rotates the display panel by 90 ° in order to switch the screen between vertical and horizontal directions. However, in the conventional thin display device stand, the height adjusting mechanism and the rotation mechanism are provided as independent mechanisms.
[0003]
When switching the screen between portrait and landscape, the display panel is raised and the display panel is rotated 90 ° at the high position to switch the screen from landscape to portrait or from portrait to landscape. And when using it vertically, the display panel is held in the vicinity of a high position. When using it horizontally long, the display panel is usually lowered to a low position in order to make the screen easier to view after switching to landscape orientation.
[0004]
[Problems to be solved by the invention]
In the conventional thin display stand, when the display panel is not so high, when the screen is switched vertically or horizontally, that is, when the display panel is rotated, the corners of the diagonal line of the display panel are usually placed on the desk. It hits the mounting surface such as the upper surface. Since it is not preferable to apply an unnecessary impact to the display panel, it is preferable that the display panel be restricted so that it cannot be rotated when the display panel is at a low position so that such an erroneous operation does not occur.
[0005]
The present invention has been made in view of the above circumstances. For a thin display device in which a rotation operation can be freely performed when the display panel is at a high position, and the rotation operation is automatically restricted when the display panel is at a low position. The purpose is to provide a stand.
[0006]
[Means for Solving the Problems]
The stand for a thin display device of the present invention that solves the above-described problems includes a first stand member that serves as a base of the stand, a vertical shaft that is vertically movable on the first stand member, and that is vertically movable. A spring for always urging the shaft upward, a lift limit defining means for regulating the lift limit of the vertical shaft, a second stand member provided on the first stand member so as to be lifted and lowered, and a display panel screen center A panel support shaft that has an axis oriented in a direction perpendicular to the screen at a position and is provided on the second stand member so as to be rotatable around the line axis;
An upright semi-disc stopper is integrally provided at the upper end of the vertical shaft, and the outer periphery of the stopper at the upper end of the vertical shaft can be fitted into the end of the panel support shaft opposite to the display panel side. An engagement portion having two arcuate engagement grooves in two perpendicular directions is provided.
[0007]
According to a second aspect of the present invention, in the stand for the thin display device according to the first aspect, the panel support shaft can be pivoted up and down around the horizontal hinge shaft horizontally with the second stand member for tilting the display panel. In addition, a wavy unevenness is formed on the outer peripheral portion of the stopper at the upper end of the vertical shaft, and a wavy unevenness that meshes with the wavy unevenness is formed in two engaging grooves of the engaging portion.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to one embodiment shown in FIGS. FIG. 1 is a partially cutaway perspective view of a thin display device stand 3 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG. In these drawings, reference numeral 1 denotes a first stand member which becomes a base of a stand 3 for a thin display device, and a second stand member 2 is provided on the first stand member 1 so as to be movable up and down. Each of the first stand member 1 and the second stand member 2 has a box shape, and the second stand member 2 is fitted to the outer periphery of the first stand member 1 and can slide up and down. . Note that the second stand member 2 can be stopped at a desired height position by a latch mechanism (not shown) or the like. That is, a height adjustment mechanism is provided.
[0009]
A vertical shaft 4 is provided in the center of the first stand member 1 so as to be vertically movable. The vertical shaft 4 has a flange 5 fixed at the intermediate portion, and is biased upward by a spring 6 through the flange 5. Further, the height limit plate 7 that extends horizontally from the side wall of the first stand member 1 is penetrated, and the elevating limit is defined by the flange 5 hitting the height control plate 7. The flange 5 and the height regulating plate 7 constitute ascending limit defining means 8 that regulates the ascending limit of the vertical shaft 4.
[0010]
Reference numeral 10 denotes a display panel mounting plate for mounting a display panel (not shown). A panel support shaft 12 is fixed vertically to the center of the display panel mounting plate 10. The axis of the panel support shaft 12 has a direction orthogonal to the screen at the center position of the display panel screen. The panel support shaft 12 is supported by the front plate portion 13a of the holding frame 13 so as to be rotatable about the axis as indicated by an arrow a. The rotation of the panel support shaft 12 in the direction of arrow a is a screen vertical / horizontal switching operation, that is, a rotation operation for rotating the display panel.
The left and right side plate portions 13b of the holding frame 13 are rotatably attached to a pair of opposing left and right L-shaped members 14 fixed to the upper surface portion of the second stand member 2 by a hinge shaft 15, whereby a panel support shaft 12 and the holding frame 13 are rotatable up and down around the hinge shaft 15. The display panel mounting plate 10, the holding frame 13, and the L-shaped member 14 are made of a metal plate.
Although illustration is omitted, the panel support shaft 12 can be arbitrarily stopped at an inclination angle in the rotation operation about the hinge shaft 15. The panel support shaft 12 is centered on the hinge shaft 15. The rotating operation is a tilt operation that changes the vertical tilt angle of the display panel.
[0011]
As shown in FIGS. 4A and 4B, an upright semicircular stopper 18 is integrally provided at the upper end of the vertical shaft 4. On the other hand, an engagement portion 20 that can be engaged with the stopper 18 is provided at an end of the panel support shaft 12 opposite to the display panel mounting plate 10, and this engagement portion 20 is shown in an enlarged manner in FIG. As described above, there are two arc-shaped engagement grooves 19 into which the outer peripheral portion of the stopper 18 at the upper end of the vertical shaft 4 can be fitted. The two engagement grooves 19 are at right angles to each other, and correspond to two rotational positions in the two right angles of the panel support shaft 12, that is, two vertical and horizontal positions of the display panel. Then, the outer peripheral portion of the stopper 18 and the engagement groove 19 are formed with wavy irregularities 18a and 19a that mesh with each other.
[0012]
In the above-described thin display stand 3, when a display panel (not shown) is moved up and down by hand, the panel support plate 10, the panel support shaft 12, the holding frame 13, the L-shaped member 14, the second stand member 2, and the like are integrated. As a result, the first stand member 1 is raised and lowered. In FIG. 1, FIG. 2, or FIG. 4, the display panel is not at a height position in use but at a height position where a rotation operation is performed. In this state, since the vertical shaft 4 is stopped at the ascending limit position when the flange 5 hits the height regulating plate 7, the engaging portion 20 at the end of the panel support shaft 12 is separated from the stopper 18 at the upper end of the vertical shaft 4. is doing. Therefore, the panel support shaft 12 can freely rotate without being restricted. That is, in this state, even if the display panel and the panel support shaft 12 are rotated, the corners of the diagonal lines of the display panel do not hit the mounting surface such as the desk surface, and the screen can be freely switched between vertical and horizontal. it can.
In this state, the operation of rotating the panel support shaft 12 in the vertical direction around the hinge shaft 15 is performed between the wavy irregularities 19a and 18a because the engaging portion 20 of the panel support shaft 12 is separated from the stopper 18. It is performed with a light feel with no resistance to meshing.
[0013]
When the panel support shaft 12 in the state of FIGS. 4 (a) and 4 (b) is lowered together with the display panel, as shown in FIGS. 5 (a) and 5 (b), the engaging portion at the end of the panel support shaft 12 is engaged. The stopper 18 of the vertical shaft 4 is fitted into one engagement groove 19 of 20. Accordingly, the rotation of the panel support shaft 12 around its axis is limited, and therefore, the screen vertical / horizontal switching operation, that is, the rotation operation of rotating the display panel around the panel support shaft 12 is limited. Therefore, there is no problem that the display panel is rotated by mistake and the corners of the diagonal line of the display panel hit the mounting surface such as the desk surface.
[0014]
In this case, since the engaging groove 19 of the engaging portion 20 and the stopper 18 of the vertical shaft 4 are meshed with each other by the wavy irregularities 19a and 18a, the panel support shaft is used for the tilting operation of the display panel as shown in FIG. When 12 is rotated in the vertical direction about the hinge shaft 15, the engaging portion 20 can rotate at every pitch of the wavy irregularities 18 a, 19 a by pushing down the vertical shaft 4 overcoming the reaction force of the spring 6. That is, the vertical rotation of the display panel is performed as a so-called click mechanism that is fixed at a pitch interval of the wavy irregularities 18a and 19a, and the panel support shaft in a tilt operation that rotates the panel support shaft 12 about the hinge shaft 15 is performed. The tilt angle of 12, that is, the tilt angle of the display panel can be stably held.
[0015]
When the display panel and the panel support shaft 12 are lowered while the engagement portion 20 at the end of the panel support shaft 12 is engaged with the stopper 18 at the upper end of the vertical shaft 4, the vertical shaft 4 is spring-engaged while being engaged. Defeat the 6 reaction force and push it down. Therefore, the rotation operation can still be limited.
[0016]
When the screen is switched from the state shown in FIGS. 5 (a) and (b), the panel support shaft 12 is once raised to a height position as shown in FIGS. 18 and the engagement portion 20 of the panel support shaft 12 are released. Then, as described above, when the display panel and the panel support shaft 12 are rotated by 90 ° and then lowered to engage the engaging portion 20 of the panel support shaft 12 with the stopper 18 of the vertical shaft 4, FIG. ) And (b). That is, the screen is switched from the vertically or horizontally long use state of FIG. 5 to the horizontally long or vertically long use state of FIG. However, it is naturally possible to use in the height position as shown in FIG.
[0017]
At a height position where the display panel cannot be rotated (the height position in FIGS. 5 and 7), when the tilt operation is attempted, the stopper and the engaging groove are meshed with wavy irregularities due to the feel of the tilt operation. Can be immediately recognized, so that it can be immediately recognized that the position cannot be rotated.
[0018]
In addition, the structure of the 1st stand member 1 and the 2nd stand member 2 is arbitrary, and does not need to be a box shape like an Example. Further, the ascent limit restricting means 8 for restricting the height of the vertical shaft 4 and the structure for supporting the panel support shaft 12 so as to be rotatable around the axis are not limited to those of the embodiment, and various design changes can be made.
[0019]
【The invention's effect】
According to the present invention, the height adjustment mechanism and the rotation mechanism of the display panel are associated with each other, and the rotation operation is automatically restricted when the display panel is at a low position. Therefore, the display panel is rotated at a low position. Thus, it is possible to prevent an erroneous operation of hitting the corner portion of the display panel against the mounting surface, and to obtain an effect that there is no possibility of giving unnecessary impact to the display panel.
[0020]
According to the second aspect of the present invention, since the vertical axis stopper and the engagement groove at the end of the panel support shaft are engaged with each other by wavy irregularities, the display panel functions as a click mechanism for the tilt operation of the display panel. The effect that the inclination angle can be stably maintained is obtained. In addition, when the tilt operation is attempted at a height position where the display panel cannot perform the rotation operation, it can be immediately recognized that the stopper and the engaging groove are engaged with each other by the wavy unevenness due to the feeling of the tilt operation, so the rotation operation cannot be performed. The effect that it can recognize immediately that it is a position is also acquired.
