Description

モニタ位置調節装置Monitor position adjustment device
　この発明は、モニタを有する表示装置において、モニタの位置や角度を調節するための技術に関し、特にモニタの高さ位置を調節する技術に関する。 This invention relates to a technique for adjusting the position and angle of a monitor in a display device having a monitor, and more particularly to a technique for adjusting the height position of the monitor.
　薄型ディスプレイ（液晶ディスプレイなど）は、テレビ番組を視聴したり、パーソナルコンピュータの操作画面を表示するなどの用途に用いられる表示装置として、近年広く普及している。この薄型ディスプレイの利点は、モニタ部分（ディスプレイ）の厚みが小さい点や、モニタ部分（ディスプレイ）の重さがブラウン管ディスプレイ等の従来製品に比べてより軽量化がされている点にある。かかるモニタ部分の軽量化等に伴ってモニタの高さ位置や角度を調節することが従来より容易となったため、様々なモニタスタンドが考え出されている。例えば、直線移動型のスタンド、円弧移動型のスタンド、折り畳み型のスタンド等のタイプが現在知られている。 A thin display (liquid crystal display or the like) has been widely used in recent years as a display device used for watching TV programs or displaying an operation screen of a personal computer. The advantages of this thin display are that the thickness of the monitor portion (display) is small and the weight of the monitor portion (display) is further reduced as compared with conventional products such as cathode ray tube displays. Since it has become easier than ever to adjust the height position and angle of the monitor along with such weight reduction of the monitor portion, various monitor stands have been devised. For example, types such as a linear movement type stand, an arc movement type stand, and a folding type stand are currently known.
　特許文献１、２に記載されているモニタ位置調節スタンド（図１８）は、モニタがスタンドベース（台座）に対して直線上を移動するタイプ（直線移動型）である（図１８は、特許文献２の図１に対応）。この直線移動型のスタンドは、スタンドベースの支持部材（例えば、特許文献２の図１に示すスタンド部３）に収納される軸（特許文献２の可動支柱４）が移動する分だけ高さ位置を調節することが可能な構造となっている。 The monitor position adjustment stand (FIG. 18) described in Patent Documents 1 and 2 is a type (linear movement type) in which the monitor moves on a straight line with respect to a stand base (pedestal) (FIG. 18 is a patent document). 2 corresponds to FIG. 1). This linear movement type stand is positioned so as to move the shaft (movable support column 4 of Patent Document 2) accommodated in a support member of the stand base (for example, the stand part 3 shown in FIG. 1 of Patent Document 2). The structure can be adjusted.
　特許文献３に記載されているモニタ位置調節スタンド（図１９）は、モニタがスタンドベースに対して円弧上を移動するタイプ（円弧移動型）である（図１９は、特許文献３の図１に対応）。この円弧移動型のスタンドは、モニタ（特許文献３の図１に示す表示部１１）がスタンドベース（特許文献３のスタンド１２）に対して円弧上を移動し、所望の位置で固定することでモニタの高さ位置や角度を調節することが可能な構造となっている。 The monitor position adjustment stand (FIG. 19) described in Patent Document 3 is a type in which the monitor moves on an arc with respect to the stand base (arc movement type) (FIG. 19 is shown in FIG. 1 of Patent Document 3). Correspondence). This arc-moving stand is configured such that a monitor (display unit 11 shown in FIG. 1 of Patent Document 3) moves on an arc with respect to a stand base (Stand 12 of Patent Document 3) and is fixed at a desired position. The monitor can be adjusted in height and angle.
　また、図２０Ａ、Ｂの側面図に示す折り畳み型のスタンド１００’は、モニタ２’およびスタンド（台座）６’それぞれに対して支持部材４’を折れ曲がり可能な構造で連結したタイプである。この折り畳み型スタンド１００’は、図２０Ａに示すモニタ２’の高さ位置が最大の状態から、図２０Ｂに示すモニタ２’の背面がほぼ載置面に接触する程度のフラットな状態まで、支持スタンド４’の長さ分だけ高さ位置を調節することが可能な構成となっており、また、モニタ２’の角度も折れ曲がり構造を利用して容易に調節（チルト）することも可能である。 20A and 20B is a foldable type stand 100 'in which the support member 4' is connected to the monitor 2 'and the stand (pedestal) 6' in a structure that can be bent. The foldable stand 100 ′ supports from the state where the height of the monitor 2 ′ shown in FIG. 20A is maximum to the flat state where the back surface of the monitor 2 ′ shown in FIG. 20B is substantially in contact with the mounting surface. The height position can be adjusted by the length of the stand 4 ', and the angle of the monitor 2' can be easily adjusted (tilted) by using a bent structure. .
　また、特許文献４に記載されているモニタ位置調節スタンド（図２１）は、弾性手段（特許文献４の図４に示す符号１７）の弾力とフリクション機構（特許文献４の図４に示す符号２１）の摩擦力によってモニタを上下方向においてフリーストップで停止させることが可能な構成となっている（図２１は、特許文献４の図４に対応）。 Further, the monitor position adjustment stand (FIG. 21) described in Patent Document 4 is provided with the elasticity of the elastic means (reference numeral 17 shown in FIG. 4 of Patent Document 4) and the friction mechanism (reference numeral 21 shown in FIG. 4 of Patent Document 4). ), The monitor can be stopped in a free stop in the vertical direction (FIG. 21 corresponds to FIG. 4 of Patent Document 4).

　しかしながら、特許文献１、２に示す直線移動型のスタンド（図１８）では、スタンドベースの支持部材（図１８に示すスタンド部３）を長くすることでモニタの昇降範囲を拡張することはできるが、モニタ２を低い位置に調節することが困難である。これは、少なくともスタンドベースの支持部材に収納される軸（図１８の可動支柱４）の長さ分だけはスタンドベース（図１８のスタンド部３）の高さを確保する必要があるという構造上の問題からである。 However, in the linear movement type stand shown in Patent Documents 1 and 2 (FIG. 18), it is possible to extend the lift range of the monitor by lengthening the support member of the stand base (stand part 3 shown in FIG. 18). It is difficult to adjust the monitor 2 to a low position. This is because the height of the stand base (stand part 3 in FIG. 18) needs to be secured at least as long as the length of the shaft (movable support column 4 in FIG. 18) accommodated in the support member of the stand base. Because of the problem.
　特許文献３に示す円弧移動型のスタンド（図１９）は、スタンドベース（図１９のスタンド１２）に対して移動する円弧部分を長くすることで、昇降位置の高低幅を広げるとともに、低い位置にモニタ（図１９に示す表示部１１）を調節することが比較的容易であるが、モニタの前後方向への移動範囲（重心位置の前後差）が大きくなってしまう。このため、転倒を防止するためにスタンドベースの前後方向の幅を広くする必要がありスタンドベースが大型化するという問題があった。また、モニタを低い位置に調節した場合にスタンドベースにモニタの背面があたってモニタの角度が調節（チルト）し難いという問題もあった。 The arc-moving type stand (FIG. 19) shown in Patent Document 3 extends the height of the elevation position by increasing the length of the arc portion that moves relative to the stand base (stand 12 in FIG. 19), and at a lower position. Although it is relatively easy to adjust the monitor (display unit 11 shown in FIG. 19), the range of movement of the monitor in the front-rear direction (difference in the position of the center of gravity) increases. For this reason, in order to prevent a fall, it was necessary to widen the width | variety of the front-back direction of a stand base, and there existed a problem that a stand base enlarged. In addition, when the monitor is adjusted to a low position, there is a problem that it is difficult to adjust (tilt) the angle of the monitor because the back of the monitor hits the stand base.
　また、図２０Ａ、Ｂに示す折り畳み型スタンド１００’も、支持部材４’を長くすることでモニタ２’の昇降高さの幅を広げることは可能であるが、上記円弧移動型のスタンドと同様、モニタ２’の前後方向への移動範囲（重心位置の前後差）が大きくなるという問題がある。このため、転倒防止のためにスタンドベース（台座）６’の前後方向の幅（図２０Ａ、Ｂに示す幅ｗ）を広くする必要がありスタンドベースが大型化するという問題があった。 20A and 20B can also widen the height of the monitor 2 'by increasing the length of the support member 4', but it is the same as the above-mentioned arc-moving stand. There is a problem that the range of movement of the monitor 2 ′ in the front-rear direction (difference in the position of the center of gravity) is increased. For this reason, it is necessary to increase the width of the stand base (base) 6 'in the front-rear direction (width w shown in FIGS. 20A and 20B) in order to prevent toppling.
　さらに、特許文献４に示すモニタ位置調節スタンド（図２１）は、モニタの位置をフリーストップで停止させることが可能に構成されているが、上記スタンドベースが大型化するという問題は解消できるものではなく、また、弾性手段（図２１に示す符号１７）の弾力とフリクション機構（図２１に示す符号２１）の摩擦力を利用するため内部構造が複雑となり、装置の耐用年数も短いという問題がある。 Furthermore, the monitor position adjustment stand (FIG. 21) shown in Patent Document 4 is configured to be able to stop the position of the monitor with a free stop. However, the problem that the stand base is enlarged cannot be solved. In addition, since the elastic force of the elastic means (reference numeral 17 shown in FIG. 21) and the frictional force of the friction mechanism (reference numeral 21 shown in FIG. 21) are used, the internal structure becomes complicated and the service life of the apparatus is short. .
　この発明は、モニタの昇降範囲の高低差を大きくし、かつ、モニタを低い位置に調節することが可能でありながらもスタンドベース（台座）が大型化しない２段リンク移動機構を備えた表示装置およびモニタ位置調節スタンドを提供することを目的とする。 The present invention provides a display device provided with a two-stage link moving mechanism that increases the height difference of the ascending / descending range of the monitor and can adjust the monitor to a low position but does not increase the size of the stand base (pedestal). And it aims at providing a monitor position adjustment stand.

　これにより、モニタ保持部や連結体が円弧移動するだけでモニタの角度が徐々に変化するので（直線移動の場合には、モニタの角度は変わらない）、モニタ保持部の角度調節部材（ヒンジ部）でのチルト角を必要最小限に設定し、または角度調節部材（ヒンジ部）を設けないで構成することが可能になる。その結果、モニタスタンドが倒れやすい状態（モニタを最上部位置や最下部位置に配置したとき）でモニタをチルトすることによる重心変動の影響を少なくすることが可能となり、スタンドベース（台座）が大型化しないモニタスタンドを提供することができる。 As a result, the angle of the monitor gradually changes only by the circular movement of the monitor holding part and the connecting body (in the case of linear movement, the angle of the monitor does not change). Therefore, the angle adjusting member (hinge part) of the monitor holding part ) Is set to the minimum necessary, or the angle adjusting member (hinge portion) can be omitted. As a result, it is possible to reduce the influence of fluctuations in the center of gravity caused by tilting the monitor when the monitor stand is easily tilted (when the monitor is placed at the uppermost position or the lowermost position), and the stand base (pedestal) is large. It is possible to provide a monitor stand that does not become a device.

　これにより、モニタ保持部が連結体に対して、または連結体が台座に対して円弧移動するだけでモニタの角度が徐々に変化するので、モニタ保持部の角度調節部材（ヒンジ部）でのチルト角を必要最小限に設定し、または角度調節部材（ヒンジ部）を設けないで構成することが可能になる。その結果、モニタスタンドが倒れやすい状態（モニタを最上部位置や最下部位置に配置したとき）でモニタをチルトすることによる重心変動の影響を少なくすることが可能となり、スタンドベース（台座）が大型化しないモニタスタンドを提供することができる。 As a result, the angle of the monitor gradually changes when the monitor holding part moves in an arc with respect to the connecting body or the connecting body with respect to the pedestal, so that the tilt at the angle adjusting member (hinge part) of the monitor holding part is changed. The angle can be set to the minimum necessary, or the angle adjusting member (hinge portion) can be provided. As a result, it is possible to reduce the influence of fluctuations in the center of gravity caused by tilting the monitor when the monitor stand is easily tilted (when the monitor is placed at the uppermost position or the lowermost position), and the stand base (base) is large. It is possible to provide a monitor stand that does not become a device.

A mounting portion for the monitor position adjusting device 102 is provided (not shown). The monitor 2 includes a circuit for displaying other images.
　図１に実線で示すモニタ位置調節装置１０２は、モニタ２を卓上に保持すると共に、モニタ２を所望の高さや角度に調節するための装置であり、モニタ保持部４、台座６、連結体８を備える。なお、図２は、図１に示すモニタ位置調節装置１０２のαーα断面図である。 A monitor position adjusting device 102 shown by a solid line in FIG. 1 is a device for holding the monitor 2 on the table and adjusting the monitor 2 to a desired height and angle. The monitor holding unit 4, the pedestal 6, and the coupling body 8 are used. Is provided. 2 is an α-α cross-sectional view of the monitor position adjusting device 102 shown in FIG.
　モニタ保持部４（図１）は、図２に示すように、モニタ２をネジ止め等により取り付けるための取付部材である取付部分４ａと、取り付けたモニタ２を保持する保持部材４ｂとを備えている。また、保持部材４ｂは、表示画面２ａの角度を調節（チルト）するためのヒンジ部４ｃを有する。これらの部材は、鉄板などの金属材料を加工したり、部品を溶接・ネジ止め等により固着して成形される。 As shown in FIG. 2, the monitor holding unit 4 (FIG. 1) includes an attachment portion 4 a that is an attachment member for attaching the monitor 2 by screwing or the like, and a holding member 4 b that holds the attached monitor 2. Yes. The holding member 4b has a hinge portion 4c for adjusting (tilting) the angle of the display screen 2a. These members are formed by processing a metal material such as an iron plate or fixing parts by welding or screwing.
　台座６（図１）は、図２に示すように、載置面に接触する平面部材６ａと、平面部材６ａに所定の角度で固着される支持部材６ｂを備えている。これらの部材は、鉄板などの金属材料を加工したり、部品を溶接・ネジ止め等により固着して成形される。なお、支持部材６bが固着される所定の角度は、モニタ２を取り付けた時に、表示装置１００が転倒しないような角度に適宜決められる。 As shown in FIG. 2, the pedestal 6 (FIG. 1) includes a flat member 6a that contacts the mounting surface and a support member 6b that is fixed to the flat member 6a at a predetermined angle. These members are formed by processing a metal material such as an iron plate or fixing parts by welding or screwing. Note that the predetermined angle at which the support member 6b is fixed is appropriately determined such that the display device 100 does not fall over when the monitor 2 is attached.
　連結体８（図１）は、図２に示すように、モニタ保持部４、台座６をそれぞれ第１の位置調節手段１０、第２の位置調節手段１１を介して連結する役割を有する部品である。このように、モニタ位置調節装置１０２は、上記モニタ保持部４、台座６、連結体８のほか、さらに、図２に示す第１の位置調節手段１０、第２の位置調節手段１１を備える。なお、図１および図２は、連結体８が台座６に対して可動範囲の中間に位置し、かつ、モニタ保持部４が連結体８に対して可動範囲の中間に位置した状態を示している。 As shown in FIG. 2, the connecting body 8 (FIG. 1) is a component having a role of connecting the monitor holding unit 4 and the pedestal 6 via the first position adjusting means 10 and the second position adjusting means 11, respectively. is there. As described above, the monitor position adjusting device 102 includes the first position adjusting means 10 and the second position adjusting means 11 shown in FIG. 2 in addition to the monitor holding unit 4, the base 6, and the connecting body 8. 1 and 2 show a state in which the connecting body 8 is located in the middle of the movable range with respect to the base 6 and the monitor holding unit 4 is located in the middle of the movable range with respect to the connecting body 8. Yes.
　第１の位置調節手段１０は、連結体８に設けられ、モニタ保持部４が外力を受けるとモニタ保持部４を連結体８に対して移動させるように構成される。例えば、図２に示すモニタ２に上方向（または下方向）の外力を与えたときに、モニタ保持部４を連結体８に対して上方向（または下方向）に移動させるための移動機構を備えており、この移動機構は、具体的には、図２に示すように、モニタ保持部４に固着されており連結体８の内部に設けられた空間を摺動する摺動部材であるスライダ１０ａと、連結体８の上部に回転軸を固定した滑車１０ｂと、その一端をスライダ１０ａに接続し、他端を滑車１０ｂを介して台座６（台座６の支持部材６ｂに固着された後述のスライダ１２）に接続したワイヤー１０ｃとによって構成される。なお、第１の位置調節手段１０に緩衝部材であるオイルダンパー、エアーダンパー（図示せず）を併せて用いてもよい。なお、連結体８の内部に設けられる空間は、図２に示す中間板９によって連結体８の筐体を内部でスライダ１０ａとスライダ１２が摺動できるように仕切ることで形成される。 The first position adjusting means 10 is provided in the connecting body 8 and is configured to move the monitor holding section 4 relative to the connecting body 8 when the monitor holding section 4 receives an external force. For example, a moving mechanism for moving the monitor holding unit 4 upward (or downward) relative to the connector 8 when an external force in the upward direction (or downward direction) is applied to the monitor 2 shown in FIG. Specifically, as shown in FIG. 2, this moving mechanism is a slider that is a sliding member that is fixed to the monitor holding portion 4 and slides in a space provided inside the coupling body 8. 10a, a pulley 10b having a rotating shaft fixed to the upper portion of the coupling body 8, one end thereof connected to the slider 10a, and the other end connected to a base 6 (a support member 6b of the base 6 fixed later) via the pulley 10b. And a wire 10c connected to the slider 12). Note that an oil damper or an air damper (not shown) that is a buffer member may be used together with the first position adjusting means 10. Note that the space provided inside the coupling body 8 is formed by partitioning the casing of the coupling body 8 by the intermediate plate 9 shown in FIG. 2 so that the slider 10a and the slider 12 can slide inside.
　第２の位置調節手段１１は、第１の位置調節手段１０が、モニタ保持部４を連結体８に対して移動させたとき、これに連動して連結体８を台座６に対して移動させるように構成される。例えば、モニタ２（図２）に上方向（または下方向）の外力を与えたときに、連動して連結体８を台座６に対して同じ上方向（または下方向）に移動させるための移動機構を備えており、この移動機構は、具体的には、図２に示すように、台座６の支持部材６ｂに固着され、連結体８の内部に設けられた空間を摺動する摺動部材であるスライダ１２と、スライダ１２を制動するように一端が接続される定荷重バネ１３（引き出し長さの長短にかかわらず、常に一定の力で往復するバネ）とによって構成される。なお、図２に示すように、スライダ１２は、滑車１０ｂを介してスライダ１０ａにワイヤー１０ｃで接続されている。定荷重バネ１３の本体（引き出し部以外）は、図２に示すように連結体８の下部に枠体１９で保持されている。なお、第２の位置調節手段１１に緩衝部材であるオイルダンパー、エアーダンパー（図示せず）を併せて用いてもよい。 The second position adjusting means 11 moves the connecting body 8 relative to the base 6 in conjunction with the monitor holding portion 4 when the first position adjusting means 10 moves the monitor holding section 4 relative to the connecting body 8. Configured as follows. For example, when an external force in the upward direction (or downward direction) is applied to the monitor 2 (FIG. 2), movement for moving the connecting body 8 in the same upward direction (or downward direction) with respect to the base 6 Specifically, as shown in FIG. 2, this moving mechanism is a sliding member that is fixed to the support member 6 b of the pedestal 6 and slides in a space provided inside the coupling body 8. And a constant-load spring 13 (a spring that always reciprocates with a constant force regardless of the length of the pull-out length). In addition, as shown in FIG. 2, the slider 12 is connected to the slider 10a with the wire 10c via the pulley 10b. As shown in FIG. 2, the main body (other than the drawer portion) of the constant load spring 13 is held by a frame body 19 below the coupling body 8. Note that an oil damper or an air damper (not shown) as a buffer member may be used in combination with the second position adjusting means 11.
　図３は、連結体８の上方から見た連結体８内部における各部材の位置関係を示す簡略図である。図３に示すように、モニタ保持部４の取付部分４ａには２つの支持部材４ｂが固着されており、支持部材４ｂに連結体８の前面の切り欠きを通して固着される２つのスライダ１０ａは連結体８の内部で中間部材１０ａ’を介して一体的に構成されている。台座６の支持部材６ｂにはスライダ１２が２つ固着されており、２つのスライダ１２は連結体８の内部で中間部材１２’を介して一体的に構成されている。 FIG. 3 is a simplified diagram showing the positional relationship of each member in the connection body 8 as viewed from above the connection body 8. As shown in FIG. 3, two support members 4b are fixed to the mounting portion 4a of the monitor holding portion 4, and the two sliders 10a fixed to the support member 4b through the notches on the front surface of the connecting body 8 are connected. The body 8 is integrally formed through an intermediate member 10a ′. Two sliders 12 are fixed to the support member 6 b of the base 6, and the two sliders 12 are integrally formed inside the coupling body 8 via an intermediate member 12 ′.
　また、支持部材４ｂに固着される２つのスライダ１０ａの中間部材１０ａ’の上方には滑車１０ｂが１つ設けられている。滑車１０ｂを介して、図３に示すように、ワイヤー１０ｃの一端はスライダ１０ａの中間部材１０ａ’に、他端は２つのスライダ１２を一体的に接続する中間部材１２’に接続されている。 Further, one pulley 10b is provided above the intermediate member 10a 'of the two sliders 10a fixed to the support member 4b. As shown in FIG. 3, one end of the wire 10c is connected to the intermediate member 10a 'of the slider 10a and the other end is connected to the intermediate member 12' integrally connecting the two sliders 12 through the pulley 10b.
　また、図３に示すように、台座６の支持部材６ｂに固着される２つのスライダ１２の中間部材１２’の下方には、これと接続される定荷重バネ１３（破線で示す）が１つ保持されており、定荷重バネ１３の引き出し部はスライダ１２の中間部材１２’に接続される。 As shown in FIG. 3, one constant load spring 13 (shown by a broken line) connected to the intermediate member 12 ′ of the two sliders 12 fixed to the support member 6b of the pedestal 6 is provided below the intermediate member 12 ′. The lead portion of the constant load spring 13 is connected to the intermediate member 12 ′ of the slider 12.
　図４に、定荷重バネの特性を示す（縦軸に復元力Fを、横軸に引き出し長さxをとっている）。図４に示すように、線バネでは、引き出し長さxが大きくなれば、それに比例してバネの復元力Fが大きくなるのに対し、定荷重バネでは、引き出し長さxが大きくなっても復元力Fは一定である。このような、引き出しストロークの長短にかかわらず復元力が一定であるという定荷重バネの特性などにより、以下に示すような２段リンク機構においてフリーストップ機能を実現することが可能になる。なお、第２の位置調節手段１１に用いられる定荷重バネ１３としては、後述するような力の釣り合いを考慮したタイプ（荷重の大きさに対応するもの）を選定する必要性がある。 Fig. 4 shows the characteristics of the constant load spring (the restoring force F is plotted on the vertical axis and the pulling length x is plotted on the horizontal axis). As shown in FIG. 4, in the case of a wire spring, if the pull-out length x increases, the restoring force F of the spring increases proportionally, whereas in the constant load spring, even if the pull-out length x increases. The restoring force F is constant. Due to such a characteristic of the constant load spring that the restoring force is constant regardless of the length of the drawing stroke, it is possible to realize a free stop function in the two-stage link mechanism as described below. As the constant load spring 13 used for the second position adjusting means 11, it is necessary to select a type (corresponding to the magnitude of the load) in consideration of force balance as described later.
　図５は、モニタ位置調節装置１０２の２段リンク機構を模式的に示す図である。以下に、図５を用いてモニタ位置調節装置１０２の移動動作および作用する力の関係について説明する。なお、図５において、モニタ２（モニタ保持部４を含む）の重さによる力をＭ１、連結体８の重さによる力をＭ２、定荷重バネ１３により連結体８が引き上げられる力をＦ１、ワイヤー１０ｃの張力をＴ１で示している。 FIG. 5 is a diagram schematically showing the two-stage link mechanism of the monitor position adjusting device 102. Hereinafter, the relationship between the moving operation of the monitor position adjusting apparatus 102 and the acting force will be described with reference to FIG. In FIG. 5, the force due to the weight of the monitor 2 (including the monitor holding unit 4) is M 1 , the force due to the weight of the coupling body 8 is M 2 , and the force with which the coupling body 8 is pulled up by the constant load spring 13. The tension of F 1 and the wire 10c is indicated by T 1 .
　図５に示す状態からモニタ２の位置を低く調節する場合、例えば、モニタ２を下方向へΔｌだけ移動させると、ワイヤー１０ｃの長さは変わらないため、これに連動して滑車１０ｂと定荷重バネ１３は一体的に下方向へΔｌ／２だけ移動する。つまり、連結体８が下方向にΔｌ／２だけ移動するにしたがって、台座６と定荷重バネ１３との距離もΔｌ／２だけ長くなる。ただし、台座６と定荷重バネ１３との距離が長くなっても、連結体８が定荷重バネ１３によって引き上げられる力Ｆ１は一定であり変わらない。 When adjusting the position of the monitor 2 low from the state shown in FIG. 5, for example, if the monitor 2 is moved downward by Δl, the length of the wire 10c does not change, and accordingly, the pulley 10b and the constant load are linked. The spring 13 integrally moves downward by Δl / 2. That is, as the connecting body 8 moves downward by Δl / 2, the distance between the base 6 and the constant load spring 13 increases by Δl / 2. However, even if the distance between the pedestal 6 and the constant load spring 13 is increased, the force F 1 by which the coupling body 8 is pulled up by the constant load spring 13 is constant and does not change.
　図５に示す状態からモニタ２の位置を高く調節する場合には、上記と逆方向に同様の動作が行われる。すなわち、モニタ２を上方向へΔｌだけ移動させると、ワイヤー１０ｃの長さは変わらないため、これに連動して滑車１０ｂと定荷重バネ１３は一体的に上方向へΔｌ／２だけ移動する。つまり、連結体８が上方向にΔｌ／２だけ移動するにしたがって、台座６と定荷重バネ１３との距離もΔｌ／２だけ短くなる。ただし、台座６と定荷重バネ１３との距離が短くなっても、連結体８が定荷重バネ１３によって引き上げられる力Ｆ１は一定であり変わらない。 When the position of the monitor 2 is adjusted to be higher from the state shown in FIG. 5, the same operation is performed in the reverse direction. That is, when the monitor 2 is moved upward by Δl, the length of the wire 10c does not change. Accordingly, the pulley 10b and the constant load spring 13 are integrally moved upward by Δl / 2. That is, as the connecting body 8 moves upward by Δl / 2, the distance between the base 6 and the constant load spring 13 is also shortened by Δl / 2. However, even if the distance between the pedestal 6 and the constant load spring 13 is shortened, the force F 1 for pulling up the connecting body 8 by the constant load spring 13 is constant and does not change.
　図５において、モニタ２と連結体８に作用する力の関係は、モニタ２については（式）Ｍ１＝Ｔ１で表され、連結体８については（式）Ｆ１＝２Ｔ１（連結体８の重さを無視した場合）で表され、外力を加えない限り作用する力がつり合った状態にある。両式から張力Ｔ１を消去すると、Ｆ１＝２Ｍ１となり、モニタ２の荷重の２倍の力が定荷重バネ１３に常時かかっていることが分かる。また、ワイヤー１０ｃには、張力Ｔ１＝Ｍ１よりモニタ２の荷重と同じ力が常時かかっている。 In FIG. 5, the relationship between the forces acting on the monitor 2 and the connecting body 8 is expressed by (formula) M 1 = T 1 for the monitor 2 and (formula) F 1 = 2T 1 (connecting body) for the connecting body 8. When the weight of 8 is ignored), the applied force is balanced unless an external force is applied. When the tension T 1 is eliminated from both equations, F 1 = 2M 1 , and it can be seen that a force twice the load of the monitor 2 is constantly applied to the constant load spring 13. Moreover, the same force as the load of the monitor 2 is always applied to the wire 10c from the tension T 1 = M 1 .
　なお、連結体８の重さによる力Ｍ２を考慮すると、モニタ２と連結体８に作用する力の関係は、モニタ２については連結体８の重さを無視した上記と同じ（式）Ｍ１＝Ｔ１で表されるが、連結体８については（式）Ｆ１＝２Ｔ１＋Ｍ２で表され、両式から得られるＦ１＝２Ｍ１＋Ｍ２と異なる。これにより、連結体８の重さによる力Ｍ２を考慮した場合、定荷重バネ１３に常時かかる力は、モニタ２の荷重の２倍以上の力（連結体８の重さ分だけ増加）になる。なお、上記と同様、ワイヤー１０ｃには、張力Ｔ１＝Ｍ１よりモニタ２の荷重と同じ力が常時かかっている。 In consideration of the weight by the force M 2 of the connector 8, the force relationship acts on the connecting body 8 and the monitor 2, the monitor 2 is as defined above ignoring the weight of the connecting member 8 (formula) M 1 = is represented by T 1, the connecting body 8 is represented by (equation) F 1 = 2T 1 + M 2, differs from the F 1 = 2M 1 + M 2 obtained from both equations. Thus, when considering the forces M 2 by the weight of the connecting body 8, always force applied to the constant force spring 13 is more than twice the force of the load of the monitor 2 (increased by the weight fraction of the connecting body 8) Become. In addition, the same force as the load of the monitor 2 is always applied to the wire 10c from the tension T 1 = M 1 as described above.
　つぎに、モニタ位置調節装置１０２によってモニタ２の位置を調節する方法について、図６～図９を用いて説明する。なお、図６、図７は、モニタ保持部４を連結体８に対して可動範囲の最上部に位置させた状態（同時に、連結体８も台座６に対して可動範囲の最上部に位置）を示している。図８、図９は、モニタ保持部４を連結体８に対して可動範囲の最下部に位置させた状態（同時に、連結体８も台座６に対して可動範囲の最下部に位置）を示している。また、図６および図８は、モニタ位置調節装置１０２の外形を示す斜視図（図１に対応）であり、図７および図９は、それぞれ図６および図８に示すモニタ位置調節装置１０２のα－α断面図（図２に対応）である。 Next, a method for adjusting the position of the monitor 2 by the monitor position adjusting device 102 will be described with reference to FIGS. 6 and 7 show a state in which the monitor holding unit 4 is positioned at the top of the movable range with respect to the connecting body 8 (at the same time, the connecting body 8 is also positioned at the top of the movable range with respect to the base 6). Is shown. 8 and 9 show a state in which the monitor holding unit 4 is positioned at the lowermost part of the movable range with respect to the connecting body 8 (at the same time, the connecting body 8 is also positioned at the lowermost part of the movable range with respect to the base 6). ing. 6 and 8 are perspective views (corresponding to FIG. 1) showing the outer shape of the monitor position adjusting device 102, and FIGS. 7 and 9 are views of the monitor position adjusting device 102 shown in FIGS. 6 and 8, respectively. FIG. 4 is an α-α sectional view (corresponding to FIG. 2).
　作業者は、図１および図２に示す状態からモニタ２を最上部に調節したい場合、モニタ２に上方向の外力を与えて、図６および図７に示すように、図２に示すスライダ１０ａの可動範囲で、モニタ２を上方向に移動させる。すると、図６および図７に示すように、図２に示すスライダ１２の可動範囲でこれと連動して連結体８が上方向に移動する。これにより、モニタ２を上方向に移動させた後、作業者がモニタ２に外力を与えないときにモニタ２の位置をフリーストップで保持することができる。 When the operator wants to adjust the monitor 2 to the uppermost position from the state shown in FIGS. 1 and 2, the operator applies an upward external force to the monitor 2, and as shown in FIGS. 6 and 7, the slider 10 a shown in FIG. In the movable range, the monitor 2 is moved upward. Then, as shown in FIGS. 6 and 7, the coupling body 8 moves upward in conjunction with this within the movable range of the slider 12 shown in FIG. Thereby, after moving the monitor 2 upward, the position of the monitor 2 can be held in a free stop when the operator does not apply an external force to the monitor 2.
　作業者は、図１および図２に示す状態からモニタ２を最下部に調節したい場合、モニタ２に下方向の外力を与えて、図８および図９に示すように、図２に示すスライダ１０ａの可動範囲で、モニタ２を下方向に移動させる。すると、図８および図９に示すように、これと連動して図２に示すスライダ１２の可動範囲で連結体８が下方向に移動する。これにより、モニタ２を下方向に移動させた後、作業者がモニタ２に外力を与えないときにモニタ２の位置をフリーストップで保持することができる。 When the operator wants to adjust the monitor 2 to the lowermost position from the state shown in FIGS. 1 and 2, the operator applies a downward external force to the monitor 2 and, as shown in FIGS. 8 and 9, the slider 10a shown in FIG. In the movable range, the monitor 2 is moved downward. Then, as shown in FIG. 8 and FIG. 9, the coupling body 8 moves downward within the movable range of the slider 12 shown in FIG. Thus, after the monitor 2 is moved downward, the position of the monitor 2 can be held in a free stop when the operator does not apply external force to the monitor 2.
　ここで、第１の位置調節手段１０（図２）は、前記モニタ保持部４を前記連結体８に対して円弧上を移動させるように構成されている（つまり、図２に示すスライダ１０ａの可動範囲である連結体８の内部空間が円弧を形成する）ため、載置面に対するモニタ２の角度は、高い方向に移動させるほど大きくなり、低い方向に移動させるほど小さくなる。 Here, the first position adjusting means 10 (FIG. 2) is configured to move the monitor holding portion 4 on an arc with respect to the coupling body 8 (that is, the slider 10a shown in FIG. 2). Therefore, the angle of the monitor 2 with respect to the mounting surface increases as it moves in the higher direction and decreases as it moves in the lower direction.
　ここで、第２の位置調節手段１１（図２）は、前記モニタ保持部４を前記連結体８に対して円弧上を移動させるように構成されている（図２に示すようにスライダ１２の可動範囲である連結体８の内部空間が円弧を形成する）ため、上記第１の位置調節手段１０の場合と同様、載置面に対するモニタ２の角度は、連結体８を高い方向に移動させるほど大きくなり、連結体８を低い方向に移動させるほど小さくなる。 Here, the second position adjusting means 11 (FIG. 2) is configured to move the monitor holding portion 4 on an arc with respect to the coupling body 8 (as shown in FIG. 2 of the slider 12). Since the internal space of the connecting body 8 that is a movable range forms an arc), the angle of the monitor 2 with respect to the mounting surface moves the connecting body 8 in the high direction as in the case of the first position adjusting means 10. It becomes so large that it becomes small, so that the connection body 8 is moved to a low direction.
　さらに、作業者は、モニタ２にヒンジ部４cを軸とする回転方向の外力を加えることにより、画面の角度を容易に調節（チルト）することも可能である。 Furthermore, the operator can easily adjust (tilt) the angle of the screen by applying an external force in the rotational direction about the hinge 4c as an axis to the monitor 2.
　なお、上記実施形態では、図２に示すように連結体８の上部に滑車１０ｂなどを設け、連結体８の下部に定荷重バネ１３などを設けることとした。すなわち、第１の位置調節手段が、前記モニタ保持部に固着した摺動部材（スライダ）と、前記連結体の上部に回転軸を固定した滑車と、その一端を当該摺動部材に接続し、他端を前記滑車を介して前記台座に接続したワイヤーとを備えており、第２の位置調節手段が、前記台座の支持部材または前記連結体に固着した摺動部材（スライダ）と、当該摺動部材を制動する定荷重バネとを備えることとしたが、かかる構成に限定されるものではない。 In the above embodiment, as shown in FIG. 2, the pulley 10 b and the like are provided on the upper part of the connecting body 8, and the constant load spring 13 and the like are provided on the lower part of the connecting body 8. That is, the first position adjusting means connects the sliding member (slider) fixed to the monitor holding portion, the pulley having the rotating shaft fixed to the upper part of the coupling body, and one end thereof to the sliding member, A wire having the other end connected to the pedestal via the pulley, and the second position adjusting means includes a sliding member (slider) fixed to the supporting member of the pedestal or the coupling body, and the sliding member. Although a constant load spring for braking the moving member is provided, the present invention is not limited to this configuration.
　例えば、図１０に示すモニタ位置調節装置１２２の断面図のように、連結体２８の上部に定荷重バネ３０ｂ、枠体３８などを設け、連結体８の下部に滑車３３、ワイヤー３４などを設けるよう構成してもよい。モニタ位置調節装置１２２の外形は、図１に示すモニタ位置調節装置１０２と同じである。 For example, as shown in the cross-sectional view of the monitor position adjusting device 122 shown in FIG. 10, the constant load spring 30 b and the frame body 38 are provided on the upper portion of the connecting body 28, and the pulley 33 and the wire 34 are provided on the lower portion of the connecting body 8. You may comprise. The external shape of the monitor position adjusting device 122 is the same as that of the monitor position adjusting device 102 shown in FIG.
　すなわち、図１０に示すように、第１の位置調節手段３０が、モニタ保持部２４に固着した摺動部材（スライダ）３０ａ（中間部材３０ａ’を有する）と、当該摺動部材３０ａを制動する定荷重バネ３０ｂとを備えており、第２の位置調節手段３１が、台座２６の支持部材２６ｂに固着した摺動部材（スライダ）３２と、連結体２８の下部に回転軸を固定した滑車３３と、その一端をモニタ保持部２４に固着した摺動部材３０ａに接続し、他端を滑車３３を介して台座２６の支持部材２６ｂに固着した摺動部材３２（中間部材３２’）に接続したワイヤー３４とを備えるよう構成してもよい。 That is, as shown in FIG. 10, the first position adjusting means 30 brakes the sliding member (slider) 30a (having the intermediate member 30a ′) fixed to the monitor holding portion 24 and the sliding member 30a. The second position adjusting means 31 includes a sliding member (slider) 32 fixed to the support member 26b of the base 26, and a pulley 33 having a rotating shaft fixed to the lower portion of the coupling body 28. And one end thereof is connected to the sliding member 30a fixed to the monitor holding portion 24, and the other end is connected to the sliding member 32 (intermediate member 32 ') fixed to the support member 26b of the base 26 via the pulley 33. You may comprise so that the wire 34 may be provided.
　図１１は、図１０に示すモニタ位置調節装置１２２の２段リンク構造を模式的に示す図である。以下に、図１１を用いてモニタ位置調節装置１２２の移動動作および作用する力の関係について説明する。なお、図１１において、モニタ２２（モニタ保持部２４を含む）の重さによる力をＭ１、連結体２８の重さによる力をＭ２、定荷重バネ３０ｂにより連結体２８が引き上げられる力をＦ１、ワイヤー３４の張力をＴ１で示している。 FIG. 11 is a diagram schematically showing a two-stage link structure of the monitor position adjusting device 122 shown in FIG. Hereinafter, the relationship between the moving operation of the monitor position adjusting device 122 and the acting force will be described with reference to FIG. In FIG. 11, the force due to the weight of the monitor 22 (including the monitor holding unit 24) is M 1 , the force due to the weight of the coupling body 28 is M 2 , and the force with which the coupling body 28 is pulled up by the constant load spring 30b. F 1 and the tension of the wire 34 are indicated by T 1 .
　図１１に示す状態からモニタ２２の位置を低く調節する場合、例えば、モニタ２２を下方向へΔｌだけ移動させると、ワイヤー３４の長さは変わらないため、これに連動して滑車３３と定荷重バネ３０ｂは一体的に下方向へΔｌ／２だけ移動する。つまり、連結体２８が下方向にΔｌ／２だけ移動するにしたがって、モニタ２２と定荷重バネ３０ｂとの距離もΔｌ／２だけ長くなる。ただし、モニタ２２と定荷重バネ３０ｂとの距離が長くなっても、連結体２８が定荷重バネ３０ｂによって引き上げられる力Ｆ１は一定であり変わらない。 When the position of the monitor 22 is adjusted to a low level from the state shown in FIG. 11, for example, if the monitor 22 is moved downward by Δl, the length of the wire 34 does not change. The spring 30b integrally moves downward by Δl / 2. That is, as the connecting body 28 moves downward by Δl / 2, the distance between the monitor 22 and the constant load spring 30b also increases by Δl / 2. However, even if the long distance between the monitor 22 and the constant force spring 30b, the force F 1 the connecting member 28 is pulled up by a constant force spring 30b does not change is constant.
　図１１に示す状態からモニタ２２の位置を高く調節する場合には、上記と逆方向に同様の動作が行われる。すなわち、モニタ２２を上方向へΔｌだけ移動させると、ワイヤー３４の長さは変わらないため、これに連動して滑車３３と定荷重バネ３０ｂは一体的に上方向へΔｌ／２だけ移動する。つまり、連結体２８が上方向にΔｌ／２だけ移動するにしたがって、台座２６と定荷重バネ３０ｂとの距離もΔｌ／２だけ短くなる。ただし、モニタ２２と定荷重バネ３０ｂとの距離が短くなっても、連結体２８が定荷重バネ３０ｂによって引き上げられる力Ｆ１は一定であり変わらない。 When the position of the monitor 22 is adjusted to be higher from the state shown in FIG. 11, the same operation is performed in the reverse direction. That is, when the monitor 22 is moved upward by Δl, the length of the wire 34 does not change. Accordingly, the pulley 33 and the constant load spring 30b are integrally moved upward by Δl / 2. That is, as the connecting body 28 moves upward by Δl / 2, the distance between the base 26 and the constant load spring 30b also decreases by Δl / 2. However, even if the distance between the monitor 22 and the constant force spring 30b is shortened, the force F 1 the connecting member 28 is pulled up by a constant force spring 30b does not change is constant.
　図１１において、モニタ２２と連結体２８に作用する力の関係は、モニタ２２については（式）Ｍ１＋Ｔ１＝Ｆ１で表され、連結体２８については（式）Ｆ１＝２Ｔ１（連結体２８の重さを無視した場合）で表され、外力を加えない限り作用する力がつり合った状態にある。両式から張力Ｔ１を消去すると、Ｆ１＝２Ｍ１となり、モニタ２２の荷重の２倍の力が定荷重バネ３０ｂに常時かかっていることが分かる。また、ワイヤー３４には、張力Ｔ１＝Ｍ１より、モニタ２２の荷重と同じ力が常時かかっている。 In FIG. 11, the relationship between the forces acting on the monitor 22 and the coupling body 28 is expressed by (formula) M 1 + T 1 = F 1 for the monitor 22, and (formula) F 1 = 2T 1 (for the coupling body 28. When the weight of the connecting body 28 is ignored), the acting force is balanced unless an external force is applied. If the tension T 1 is eliminated from both equations, F 1 = 2M 1 , and it can be seen that a force twice the load of the monitor 22 is constantly applied to the constant load spring 30b. Moreover, the same force as the load of the monitor 22 is always applied to the wire 34 from the tension T 1 = M 1 .
　なお、連結体２８の重さによる力Ｍ２を考慮すると、モニタ２２と連結体２８に作用する力の関係は、モニタ２２については連結体２８の重さを無視した上記と同じ（式）Ｍ１＋Ｔ１＝Ｆ１で表されるが、連結体２８については（式）Ｆ１＋Ｍ２＝２Ｔ１で表され、両式から張力Ｔ１を消去して得られるＦ１＝２Ｍ１＋Ｍ２と異なる。これにより、連結体２８の重さによる力Ｍ２を考慮した場合、定荷重バネ３０ｂに常時かかる力は、モニタ２２の荷重の２倍以上の力（連結体２８の重さ分だけ増加）になる。なお、上記と異なり、ワイヤー３４には、張力Ｔ１＝Ｍ１＋Ｍ２より、モニタ２２および連結体２８の総荷重と同じ力が常時かかっている。つまり、図５に示す場合より、張力Ｔ１が大きくなる以外は、同じである。 In consideration of the weight force M 2 by the connecting member 28, the force relationship acts on the monitor 22 and the connecting member 28, the monitor 22 is as defined above ignoring the weight of the connecting member 28 (the formula) M 1 + T 1 = F 1 , but the connection body 28 is represented by (formula) F 1 + M 2 = 2T 1 , and F 1 = 2M 1 + M 2 obtained by eliminating the tension T 1 from both formulas. And different. Thus, when considering the forces M 2 by the weight of the connecting member 28, the force applied constantly to the constant force spring 30b is more than twice the force of the load of the monitor 22 (only the weight fraction increase of the coupling member 28) Become. Unlike the above, the wire 34 is always subjected to the same force as the total load of the monitor 22 and the coupling body 28 due to the tension T 1 = M 1 + M 2 . That is, compared with the case shown in FIG. 5, except that the tension T 1 is increased is the same.
