表示パネル支持装置 Display panel support device
技術分野 Technical field
[0001] この発明は、液晶パネルなどからなる表示パネルを、高さおよび支持角度 (傾斜角) の調整が可能に支持し、かつ折畳みが可能な表示パネル支持装置に関する。 The present invention relates to a display panel support device that supports a display panel made of a liquid crystal panel or the like so that the height and support angle (tilt angle) can be adjusted and can be folded.
背景技術 Background art
[0002] 従来、液晶パネルやプラズマディスプレイパネルなどの表示パネルは、高さおよび 支持角度 (傾斜角)の調整が可能な支持装置で支持されているものが提案されてい この表示パネルの支持装置としては、基台に対し表示パネルはアームを介して支 持され、表示パネルとアームはブレーキ付回転軸(一定以上の力を加えて始めて回 転させることができる軸)で連結され、基台とアームは、ブレーキ付回転軸で連結され Conventionally, display panels such as liquid crystal panels and plasma display panels have been proposed to be supported by a support device capable of adjusting the height and support angle (tilt angle). The display panel is supported on the base via an arm, and the display panel and the arm are connected by a rotating shaft with a brake (a shaft that can be rotated only after a certain amount of force is applied). The arm is connected by a rotating shaft with a brake.
、前記アーム力 Sリンク機構で構成されているもの(例えば、特許文献 1参照)が提案さ れている。この支持装置によれば、アームは基台との回転軸で回転させることができ 、高さの調整ができ、このとき、アームはリンク機構で構成されているので、表示パネ ルの傾斜角を変化させることなく高さの調整ができ、表示パネルはアームとの回転軸 で回転させることができ傾斜角の調整ができる。 A structure composed of the arm force S-link mechanism has been proposed (for example, see Patent Document 1). According to this support device, the arm can be rotated by the rotation axis with the base, and the height can be adjusted. At this time, since the arm is configured by the link mechanism, the inclination angle of the display panel can be adjusted. The height can be adjusted without changing, and the display panel can be rotated around the axis of rotation with the arm, and the tilt angle can be adjusted.
[0003] また、基台に対し表示パネルはアームを介して支持され、表示パネルとアームおよ びアームと基台は、ヒンジ部で揺動可能に連結され、このヒンジ部に捩りばねが介装 された支持装置 (例えば、特許文献 2参照)が提案されている。この支持装置によれ ば、アームを基台とのヒンジ部で揺動させることで高さの調整ができ、表示パネルをァ ームとのヒンジ部で揺動させることで傾斜角の調整ができる。 [0003] In addition, the display panel is supported with respect to the base via an arm, and the display panel and the arm and the arm and the base are connected to be swingable at a hinge portion, and a torsion spring is interposed in the hinge portion. A mounted support device (see, for example, Patent Document 2) has been proposed. According to this support device, the height can be adjusted by swinging the arm at the hinge portion with the base, and the tilt angle can be adjusted by swinging the display panel at the hinge portion with the arm. .
[0004] さらに、基台に対し表示パネルはアームを介して支持され表示パネルとアームおよ びアームと基台は、枢軸にて回動可能に連結され、アームの中間部は、リンクの一端 側で回動可能に支持され、リンクの他端側は前後移動可能な移動部材に連結され、 この移動部材には螺子扦が螺合されている支持装置 (例えば、特許文献 3参照)が 提案されている。この支持装置によれば螺子扦を正逆に回転させれば、移動部材を
前後に移動させることができ、それによりリンクを介しアームを起伏させ高さの調整が できるものである。 [0004] Furthermore, the display panel is supported with respect to the base via an arm, and the display panel, the arm, and the arm and the base are connected to each other so as to be pivotable. An intermediate portion of the arm is one end of the link. A support device is proposed in which the other end of the link is connected to a movable member that can move back and forth, and a screw rod is screwed onto the movable member (see, for example, Patent Document 3). Has been. According to this support device, when the screw rod is rotated forward and backward, the moving member is moved. It can be moved back and forth, and the arm can be raised and lowered via the link to adjust the height.

発明の開示 Disclosure of the invention
発明が解決しょうとする課題 Problems to be solved by the invention
[0005] 前記特許文献 1に示すような表示パネルとアームおよび基台とアームと力 S、ブレー キ付回転軸(一定以上の力を加えて始めて回転させることができる軸)で連結されて いるものは、表示パネルの高さおよび傾斜角は、ブレーキ付回転軸で姿勢保持がな されており、ブレーキ付回転軸のブレーキ力以上の力を加えることでアームを起伏さ せて高さの調整および表示パネルを可動して傾斜角の調整ができるものである。従 つて、ブレーキ付回転軸のブレーキ力は、表示パネルの重量を支持して姿勢の保持 できるものでなければならないのである程度高くなければならず、そのため高さ調整 および傾斜角の調整は、相当の力が必要となり操作性が悪い課題がある。また、表 示パネルを大きくし重量が重くなると、更に大きなブレーキ力が必要となるために、操 作性が一層悪くなるし、支持できる表示パネルにも限界が生ずる。また、引用文献 1 の支持装置では、折り畳んだ際の厚さを薄くする考慮は、何ら開示されていない。 [0005] As shown in Patent Document 1, the display panel is connected to the arm, the base, the arm, the force S, and a rotating shaft with a brake (a shaft that can be rotated only when a certain force is applied). For the display panel, the height and inclination angle of the display panel is maintained by the rotating shaft with brake, and the height is adjusted by raising and lowering the arm by applying a force greater than the braking force of the rotating shaft with brake. In addition, the tilt angle can be adjusted by moving the display panel. Therefore, the braking force of the rotating shaft with brake must be high enough to support the weight of the display panel and maintain its posture, so height adjustment and inclination angle adjustment are considerable. There is a problem that power is required and operability is bad. Also, if the display panel is made larger and the weight is heavier, a greater braking force is required, so that the operability is further deteriorated and the display panel that can be supported is limited. Moreover, in the support apparatus of the cited reference 1, no consideration is given to reducing the thickness when folded.
[0006] また、前記特許文献 2に示すような表示パネルとアームおよび基台とアームと力 捩 りばねを介装するヒンジ部で連結されているものは、表示パネルの重量には捩りばね で対抗するため、比較的大きな捩りばねを用いる必要があり、また、ばね特性のため アームの低位置では持ち上げ力が大きすぎ、アームの高位置では持ち上げ力が不 充分となる傾向があり、アームの起伏の角度、表示パネルの傾斜角によって操作性 が変化するし、大きく重量のある表示パネルの支持装置には不適である課題がある。 要するに、捩りばね等を直接アーム作動角範囲で捩じって使用することにおいては、 作用点に変化がない限り角度に比例して直線的な特性となり釣り合いのバランス特 性が良くないので、フリクション機構等(摺動摩擦)に頼るところが大きく操作性が悪く なる。
さらに、特許文献 3のような支持装置では高さの調整に螺子扦の操作が必要のため に、操作が面倒となる不都合がある。 [0006] In addition, a display panel, an arm, a base, an arm, and a hinge portion that interposes a force torsion spring as shown in Patent Document 2 are torsion springs for the weight of the display panel. To counteract, it is necessary to use a relatively large torsion spring, and because of the spring characteristics, the lifting force tends to be too large at the lower position of the arm, and the lifting force tends to be insufficient at the higher position of the arm. The operability changes depending on the undulation angle and the tilt angle of the display panel, and there is a problem that is unsuitable for a large and heavy display panel support device. In short, when a torsion spring or the like is used by directly twisting it within the arm operating angle range, linear characteristics are proportional to the angle unless the operating point changes, and the balance characteristics of the balance are not good. The reliance on the mechanism (sliding friction) is large and the operability is poor. Furthermore, since the support device as in Patent Document 3 requires the operation of the screw rod for adjusting the height, there is a disadvantage that the operation becomes troublesome.
[0007] また、従来の支持装置は、総じて表示パネルの重量に対抗した、作動範囲におけ るバランス特性が良くないのでフリクション (摺動摩擦)機構等に頼るところが大きぐ 操作性が重く悪い課題、従来の支持装置は、スリム化、小型化が不充分で折り畳ん だ際の厚みがあり、保管や移送するための場所を大きくとるため経済性にも課題があ つた。 [0007] In addition, conventional support devices generally have poor balance characteristics in the operating range against the weight of the display panel, and therefore rely heavily on a friction (sliding friction) mechanism or the like. Conventional support devices are insufficiently slim and small in size, have a thickness when folded, and have a problem in terms of economy because they have a large space for storage and transportation.
[0008] この発明は、このような課題を解決せんと提案されたものであり、その目的は、ばね 特性が表示パネル重量に対する昇降時(高さ調整時)の変動モーメントに対抗した 完全バランス特性を有し、非常に軽い力で動かす(高さ調整)ができ操作性が良ぐ 昇降範囲(高さ調整範囲)にお!/、て常にバランス静止(フリーストップ)ができ、余分な 空間を排除し、ばねのスペース分だけのアームの厚さとなるようスリム化(薄型)し、折 り畳んだ際の厚みも薄い表示パネルの支持装置の提供にある。 [0008] The present invention has been proposed to solve such a problem, and its purpose is to achieve a perfect balance characteristic in which the spring characteristic counters the fluctuation moment during the elevation (height adjustment) relative to the weight of the display panel. It can be moved with very light force (height adjustment) and has good operability! In the ascending / descending range (height adjustment range)! The aim is to provide a display panel support device that is slimmed down (thinned) so that the thickness of the arm is as much as the space of the spring, and is thin when folded.
課題を解決するための手段 Means for solving the problem
[0009] 前記課題を解決するため、この発明の表示パネル支持装置は、基台に回動可能に 軸着したアームの先端に、表示パネル取付用フレームが回動可能に軸着され、該フ レームに表示パネルを取付ける表示パネルの支持装置であって、 [0009] In order to solve the above-mentioned problems, in the display panel support device of the present invention, a display panel mounting frame is pivotally attached to the tip of an arm pivotally attached to a base, A display panel support device for attaching a display panel to a frame,
前記アームはリンク機構で構成され、表示パネル取付用フレームは、該リンク機構 のリンク軸にフリクション機構を介在して回動可能に軸着され、 The arm is composed of a link mechanism, and the display panel mounting frame is pivotally attached to the link shaft of the link mechanism via a friction mechanism.
前記リンク機構には、主に表示パネル取付用フレームに取付けた表示パネルの重 量による回転モーメントに対抗するばねが設けられていることを特徴とする。 The link mechanism is provided with a spring that opposes a rotational moment mainly due to the weight of the display panel mounted on the display panel mounting frame.
前記ばねは、引張ばね又は圧縮ばねにすると、簡単な構成において主に表示パネ ルの重量による回転モーメントに対抗させることが可能となるので好ましい。 If the spring is a tension spring or a compression spring, it is possible to counter the rotational moment mainly due to the weight of the display panel with a simple configuration.
この発明で「主に表示パネルの重量による回転モーメントに対抗する」とは、主に表 示パネルの重量によりアーム(リンク機構)が基台に向かって下向き(取付用フレーム に取付けられた表示パネルの高さ位置を降下させる方向)に回動しょうとする回転モ 一メントに対し反対方向(表示パネルの位置を高くする方向)に付勢して対抗する意 味である。また、「主に」表示パネルの重量による回転モーメントに対抗する、としたの
は、アームには表示パネルの重量による回転モーメントだけでなぐ他の取付用フレ ーム等の重量モーメントも付加されるが、大部分は表示パネルの重量による回転モ 一メントであることにより「主に」とした。 In this invention, “mainly against the rotational moment due to the weight of the display panel” means that the arm (link mechanism) faces downward toward the base mainly due to the weight of the display panel (the display panel attached to the mounting frame). It is meant to counteract by urging in the opposite direction (in the direction to raise the position of the display panel) against the rotational moment to be rotated in the direction of lowering the height position. In addition, “mainly” to counter the rotational moment due to the weight of the display panel In addition to the rotational moment due to the weight of the display panel, the arm is also subject to other moments such as other mounting frames. "".
[0010] これにより表示パネル取付用フレームに取付けられた表示パネルは、リンク機構で 構成するアームを基台に対し回動(上下動)させることによって、高さの調整ができる 。この時、リンク機構は、表示パネルの重量による回転モーメントに対抗するばねが 設けられているので、高さの調整した外力を取り除くと、主に表示パネルの重量によ る回転モーメントとこの回転モーメントに対抗するばねのばね力がバランスし、バラン ス静止してフリーストップするし、軽い力で調整が可能となり操作性も良好となる。また 、アームはリンク機構で構成されているので、表示パネルの高さを調整しても表示パ ネルの傾斜角は変わらない。表示パネルは、フリクション (摩擦抵抗)機構を介在する リンク軸を中心に回動することで、傾斜角の調整が可能となる。また、調整した傾斜角 は、フリクション (摩擦抵抗)機構によりその姿勢を保持する。 Thus, the height of the display panel mounted on the display panel mounting frame can be adjusted by rotating (up-and-down movement) the arm formed by the link mechanism with respect to the base. At this time, since the link mechanism is provided with a spring that counters the rotational moment due to the weight of the display panel, if the external force whose height is adjusted is removed, the rotational moment mainly due to the weight of the display panel and the rotational moment The spring force of the spring against the balance is balanced, the balance stops and free-stops, and adjustment is possible with a light force, resulting in good operability. Further, since the arm is constituted by a link mechanism, the tilt angle of the display panel does not change even if the height of the display panel is adjusted. The display panel can be adjusted with respect to the tilt angle by pivoting about a link shaft with a friction (friction resistance) mechanism interposed therebetween. The adjusted inclination angle is maintained by a friction (friction resistance) mechanism.
また、アーム(リンク機構)を基台の軸着部で回動し表示パネル取付用フレームをァ ーム(リンク機構のリンク軸)との軸着部で回動し、基台の上に折り畳むことが可能とな In addition, the arm (link mechanism) is rotated at the base mounting portion of the base, and the display panel mounting frame is rotated at the shaft mounting portion with the arm (link shaft of the link mechanism) and folded on the base. Became possible
[0011] 前記リンク機構が、四節リンクであると、構成が容易であるし、確実な作動とすること ができる。 [0011] When the link mechanism is a four-bar link, the configuration is easy and a reliable operation can be achieved.
また、リンク機構を形成するリンク部材が、 2枚の並行する板状体で構成すると、ァ ームの厚みを薄くできる。また、主に表示パネルの重量による回転モーメントに対抗 するばねを、この並行する板状体の間に内蔵すると、アームの厚みを増加させること なぐばねを設けること力 Sできる。従って、アームの厚みを薄くできる。また、ばねは、 板状体の間に内蔵するので、他の部材に干渉されることが防止され、確実な作動が 保障される。 Further, if the link member forming the link mechanism is composed of two parallel plate-like bodies, the thickness of the arm can be reduced. In addition, if a spring that mainly counteracts the rotational moment due to the weight of the display panel is built in between these parallel plates, it is possible to provide a spring S that does not increase the thickness of the arm. Therefore, the thickness of the arm can be reduced. Further, since the spring is built in between the plate-like bodies, it is prevented from being interfered with by other members, and a reliable operation is ensured.
[0012] また、この発明の表示パネル支持装置における前記リンク機構を形成するリンク部 材の表示パネル取付用フレームが軸着される部分は、曲折されて立上り部となって おり、表示パネル取付用フレームは、該立上り部に軸着されていることを特徴とする。 これにより表示パネル支持装置を折り畳んだ際、この立上り部の高さ内に表示パネ
ル支持装置の一部、例えば、表示パネル取付用フレーム部分を収めることができる ので、表示パネル支持装置を折り畳んだ際の厚さを薄くすることができる。 [0012] Further, in the display panel support device of the present invention, the portion of the link member forming the link mechanism on which the display panel mounting frame is pivotally attached is bent to form a rising portion, which is used for mounting the display panel. The frame is pivotally attached to the rising portion. Thus, when the display panel support device is folded, the display panel is within the height of the rising portion. Since a part of the screen support device, for example, the display panel mounting frame portion can be accommodated, the thickness when the display panel support device is folded can be reduced.
[0013] また、この発明の表示パネル支持装置の前記表示パネル取付用フレームには、回 動を一定範囲に規制する規制手段と、該規制手段の規制を解除する解除手段とが 設けられて!/、ることを特徴とする。 [0013] Further, the display panel mounting frame of the display panel support device of the present invention is provided with a restricting means for restricting the rotation to a certain range and a releasing means for releasing the restriction of the restricting means! /, Characterized by.
これにより使用時には表示パネル取付用フレームに取り付けた表示パネルの傾斜 角の調整範囲を規制手段で一定範囲に規制し、不使用時や輸送時には解除手段 で解除し回動範囲を拡大して折り畳みを可能とすることができる。 In this way, the adjustment range of the tilt angle of the display panel mounted on the display panel mounting frame is restricted to a certain range by the restricting means during use, and when not in use or transported, it is released by the releasing means and the rotation range is expanded to fold the display panel. Can be possible.

[0015] (5)表示パネルを取り付けたフレームは、リンク機構のリンク軸にフリクション機構を 介在して回動可能に軸着されているので、表示パネルはリンク軸を中心に回動させ、 傾斜角を調整することができる。調整した傾斜角は、フリクション機構で姿勢保持され [5] (5) Since the frame to which the display panel is attached is pivotally attached to the link shaft of the link mechanism via a friction mechanism, the display panel is rotated around the link shaft and tilted. The corner can be adjusted. The adjusted tilt angle is maintained by the friction mechanism.

[0018] 同図において表示パネル支持装置は、基台 2と、該基台 2に回動可能に軸着され たアーム 3と、該アーム 3の先端に回動可能に軸着された表示パネル取付用フレーム 4とで構成され、表示パネル 1は、表示パネル取付用フレーム 4に取り付けられ、図 2 に示すようにアーム 3を基台 2の軸着部を中心に回動(上下動)することによって表示 パネル 1の高さの調整ができ、図 3に示すように表示パネル取付用フレーム 4をァー ム 3との軸着部を中心に回動(前後動)することによって表示パネル 1の傾斜角の調
整ができる構成となっている。また、この構成では、図 2において表示パネル取付用 フレーム 4を矢印 X方向に回動させ、アーム 3を矢印 Y方向に回動させることによって 、図 4に示すように折り畳むことができる。 In the same figure, the display panel support device includes a base 2, an arm 3 pivotally attached to the base 2, and a display panel pivotally attached to the tip of the arm 3. The display panel 1 is mounted on the display panel mounting frame 4 and pivots (moves up and down) around the axis 2 of the base 2 as shown in FIG. By adjusting the height of the display panel 1 as shown in FIG. 3, the display panel mounting frame 4 is pivoted (back and forth) about the axis 3 with the arm 3 as shown in FIG. Tilt angle It can be adjusted. In this configuration, the display panel mounting frame 4 can be folded as shown in FIG. 4 by rotating the display panel mounting frame 4 in the arrow X direction and the arm 3 in the arrow Y direction in FIG.
前記アーム 3はリンク機構 5で構成され、表示パネル取付用フレーム 4は、該リンク 機構 5のリンク軸 6にフリクション機構 15 (詳細は後述する)を介在させて回動可能に 軸着されている。従って、アーム 3を基台 2との軸着部を中心に回動(上下動)させて 高さの調整をしても、アーム 3がリンク機構 5で構成されているため、表示パネル 1の 傾斜角は変わらない。表示パネル 1の傾斜角は、リンク軸 6を中心に回動(前後動)す ることによって実行できる。表示パネル 1の傾斜角の姿勢保持はフリクション機構 15 で保持される。 The arm 3 is composed of a link mechanism 5, and the display panel mounting frame 4 is pivotally attached to the link shaft 6 of the link mechanism 5 with a friction mechanism 15 (details will be described later) interposed therebetween. . Therefore, even if the height of the arm 3 is adjusted by rotating (up and down) the arm 3 around the pivot point with the base 2, the arm 3 is composed of the link mechanism 5. The inclination angle does not change. The tilt angle of the display panel 1 can be executed by rotating (back and forth) about the link shaft 6. The attitude of the tilt angle of the display panel 1 is held by the friction mechanism 15.
また、アーム 3を回動(上下動)させて高さの調整をする際に、アーム 3を構成するリ ンク機構 5には、表示パネル 1の重量による回転モーメントに対抗してバランスさせる 引張ばね 7を設け、常にバランス静止、即ち、フリーストップが可能となる構成を採用 している。 In addition, when adjusting the height by rotating (moving up and down) the arm 3, the link mechanism 5 constituting the arm 3 is balanced against the rotational moment due to the weight of the display panel 1. 7 is adopted, and a configuration that always allows balance stationary, that is, free stop is adopted.

[0020] アーム 3を構成するリンク機構 5は、リンク部材が板状体で形成された第 1リンク部材 8と第 2リンク部材 9を備え、この第 1リンク部材 8と第 2リンク部材 9は並行して設けられ ている。詳しくは第 1および第 2リンク部材 8、 9の板状体は長方形で、その長手方向 の両側は折り曲げられて側壁 8a、 8b、 9a、 9bに形成され、第 2リンク部材 9の幅が第 1リンク部材 8の幅より小さく形成され、この第 1および第 2リンク部材 8、 9を、両側壁 8 a、 8b、 9a、 9bが対向する格好で並行させて重ね合わせている。すると第 2リンク部 材 9は、幅力 S、第 1リンク部材 8より小さいため、第 1リンク部材 8の側壁 8a、 8b内に嵌 入して重ね合わさり、並行する第 1リンク部材 8と第 2リンク部材 9との間には、側壁 8a 、 8b、 9a、 9bの高さ分の空間(スペース)が形成される。この空間に引張ばね 7が内 蔵される。これによりアーム 3の厚さを薄くすることができると共に、引張ばね 7の他の 部材からの干渉を防止できる。
[0021] このように形成された第 1リンク部材 8と第 2リンク部材 9の下端は、側壁 8a、 8b間お よび側壁 9a、 9b間に揷通された軸 11、 12により基台 2に設けられたブラケット 10に 回動可能に取り付けられる。本例では軸 11、 12は共通の軸受部材 13でブラケット 1 0に取り付けられ、各軸間の「ガタ」をなくし、摺動異音の発生を防止し、滑らかな動き が可能で操作性および耐久性の向上を図っている。また、軸 11、 12のブラケット 10 への取付位置は、第 1リンク部材 8の方が上方に位置し、第 2リンク部材 9の方が斜め 下方に位置している。 The link mechanism 5 constituting the arm 3 includes a first link member 8 and a second link member 9 in which the link member is formed of a plate-like body, and the first link member 8 and the second link member 9 are They are provided in parallel. Specifically, the plate-like bodies of the first and second link members 8 and 9 are rectangular, and both longitudinal sides thereof are bent to form side walls 8a, 8b, 9a and 9b, and the width of the second link member 9 is the first. It is formed smaller than the width of one link member 8, and the first and second link members 8, 9 are overlapped in parallel so that both side walls 8a, 8b, 9a, 9b face each other. Then, since the second link member 9 is smaller in width force S and smaller than the first link member 8, the second link member 9 is inserted into the side walls 8a and 8b of the first link member 8 and overlapped therewith. Between the two link members 9, spaces corresponding to the heights of the side walls 8a, 8b, 9a, and 9b are formed. A tension spring 7 is built in this space. Thereby, the thickness of the arm 3 can be reduced, and interference from other members of the tension spring 7 can be prevented. [0021] The lower ends of the first link member 8 and the second link member 9 formed in this way are attached to the base 2 by shafts 11 and 12 threaded between the side walls 8a and 8b and between the side walls 9a and 9b. Attached to the provided bracket 10 so as to be rotatable. In this example, the shafts 11 and 12 are attached to the bracket 10 with a common bearing member 13 to eliminate the “backlash” between the shafts, to prevent the occurrence of sliding noise, and to enable smooth movement and ease of operation. Durability is improved. Further, the mounting positions of the shafts 11 and 12 to the bracket 10 are such that the first link member 8 is located above and the second link member 9 is located obliquely below.
[0022] 第 1リンク部材 8の側壁 8a、 8bの上端は、折り曲がり立上り部 14に形成され、この側 壁 8a、 8bの立上り部 14に、表示パネル 1の取付用フレーム 4がリンク軸 6、 6によって 回動可能に取付けられる。このリンク軸 6、 6には、図 8、図 9および図 10に示すように フリクション (摩擦抵抗、あるいは摺動抵抗ともいう)機構 15を介して表示パネル取付 用フレーム 4が取り付けられる。 [0022] The upper ends of the side walls 8a, 8b of the first link member 8 are formed at the bent rising portions 14, and the mounting frame 4 of the display panel 1 is connected to the link shaft 6 at the rising portions 14 of the side walls 8a, 8b. , 6 can be pivotally attached. A display panel mounting frame 4 is attached to the link shafts 6 and 6 via a friction (also referred to as frictional resistance or sliding resistance) mechanism 15 as shown in FIGS.
なお、この第 1リンク部材 8の軸 1 1への取付部および第 2リンク部材 9の軸 12への取 付部の、いずれか一方または双方にはフリクション機構を介在させてもよい。 Note that a friction mechanism may be interposed in one or both of the attachment portion of the first link member 8 to the shaft 11 and the attachment portion of the second link member 9 to the shaft 12.
[0023] 図 8は、リンク軸 6、 6にフリクション機構 15を介在して表示パネル取付用フレーム 4 が取り付けられた部分の斜視図、図 9はリンク軸 6部分の断面図、図 10はリンク軸 6部 分の分解斜視図である。 FIG. 8 is a perspective view of a portion where the display panel mounting frame 4 is attached to the link shafts 6 and 6 with the friction mechanism 15 interposed therebetween, FIG. 9 is a cross-sectional view of the link shaft 6 portion, and FIG. FIG. 6 is an exploded perspective view of six parts of a shaft.
フリクション機構 15は、リンク軸 6が非円形断面形状、例えば、 Dカットあるいは WD カット形状であり、このリンク軸 6に第 1リンク部材 8および表示パネル取付用フレーム 4は円形孔で回転可能に取り付けられ、図 9に示すようにこの第 1リンク部材 8の立上 り部 14の両側および表示パネル取付用フレーム 4の両側には、リンク軸 6の非円形 形状に対応する非円形孔の摩擦板 (フリクション座金) 16が回転不可で軸方向移動 可能に押圧当接して揷着されて構成されている。従って、表示パネル取付用フレー ム 4は、摩擦板 16との間の摩擦抵抗(摺動抵抗)により、一定以上の力を加えないと 回動できず、その位置を保持する。この時の摩擦抵抗の強弱は、ナット 17での締め 付け力を調整することによって調整できる。これにより表示パネル取付用フレーム 4に 取付けた表示パネル 1は、一定の力を加えることによって傾斜角の調整ができ、その 力を取り除くとその姿勢を保持する。本例では、両方の側壁 8a、 8bに設けた両方のリ
ンク軸 6、 6にフリクション機構 15が設けられているので、確実なフリーストップが可能 となるし、両方のフリクション機構 15、 15で表示パネル 1の重量に対抗するので、各 フリクション機構 15の摩擦抵抗は弱目に設定できるので、軽い力で動かす事ができ 操作性を良くする事ができる。 In the friction mechanism 15, the link shaft 6 has a non-circular cross-sectional shape, for example, a D-cut or WD-cut shape, and the first link member 8 and the display panel mounting frame 4 are rotatably mounted on the link shaft 6 through a circular hole. As shown in FIG. 9, friction plates with non-circular holes corresponding to the non-circular shape of the link shaft 6 are formed on both sides of the rising portion 14 of the first link member 8 and on both sides of the display panel mounting frame 4. (Friction washer) 16 is configured to be pressed and abutted so as to be non-rotatable and axially movable. Therefore, the display panel mounting frame 4 cannot be rotated unless a force of a certain level or more is applied due to the frictional resistance (sliding resistance) between the display panel and the position of the display panel mounting frame 4. The strength of the frictional resistance at this time can be adjusted by adjusting the tightening force with the nut 17. As a result, the display panel 1 mounted on the display panel mounting frame 4 can be adjusted in inclination angle by applying a certain force, and when the force is removed, the display panel 1 maintains its posture. In this example, both ribs provided on both side walls 8a and 8b are used. Since the friction mechanisms 15 are provided on the link shafts 6 and 6, a reliable free stop is possible, and both friction mechanisms 15 and 15 counteract the weight of the display panel 1, so the friction of each friction mechanism 15 Since the resistance can be set weakly, it can be moved with a light force and the operability can be improved.
[0024] また、前記リンク軸 6には、略円形のストッパ板 18が回転不可に設けられており、こ のストッパ板 18の外周面には切欠 18aが設けられている。 In addition, a substantially circular stopper plate 18 is provided on the link shaft 6 so as not to rotate, and a notch 18 a is provided on the outer peripheral surface of the stopper plate 18.
一方、表示パネル取付用フレーム 4には、係止板 19が前記ストッパ板 18の外周面 に向かって摺動自在に設けられており、この係止板 19は、ばね 20にて押圧されてス トツパ板 18の外周面に当接している。 On the other hand, the display panel mounting frame 4 is provided with a locking plate 19 that is slidable toward the outer peripheral surface of the stopper plate 18, and this locking plate 19 is pressed by a spring 20 to slide. It is in contact with the outer peripheral surface of the topper plate 18.
従って、係止板 19がストッパ板 18の切欠 18aに位置するときは、その切欠 18aの範 囲でしか回動できず、傾斜角の調整もこの範囲であるが、ばね 20のばね力に杭して 係止板 19を摺動し、ストツバ板 18の切欠 18aより外すことにより表示パネル取付用フ レーム 4の回動は規制が解除されて自由に可能となる。これが表示パネル取付用フ レーム 4の、回動を一定範囲に規制する規制手段と、該規制手段の規制を解除する 解除手段となる。 Therefore, when the locking plate 19 is located in the notch 18a of the stopper plate 18, it can only be rotated within the range of the notch 18a, and the inclination angle can be adjusted within this range. Then, by sliding the locking plate 19 and removing it from the notch 18a of the staggered plate 18, the rotation of the display panel mounting frame 4 is released as the restriction is released. This is the restricting means for restricting the rotation of the display panel mounting frame 4 to a certain range and the releasing means for releasing the restriction of the restricting means.
なお、軸受部材 21のリンク軸 6への取付部の外周面に切欠を設ける等のストッパ板 18と同様の構成を設けることによって、軸受部材 21にストッパ板 18と同様の機能をも たせること力 Sできる。この場合の係止板 19は、軸受部材 21のリンク軸 6への取付部の 外周面に向けて進退するようにすることは当然である。この場合は、ストツバ板 18は 不要となり、部品点数はその分減少できる。 The bearing member 21 has the same function as the stopper plate 18 by providing a configuration similar to the stopper plate 18 such as providing a notch on the outer peripheral surface of the attachment portion of the bearing member 21 to the link shaft 6. S can. Naturally, the locking plate 19 in this case is advanced and retracted toward the outer peripheral surface of the attachment portion of the bearing member 21 to the link shaft 6. In this case, the stagger plate 18 is not necessary, and the number of parts can be reduced accordingly.
[0025] また、第 1リンク部材 8の前記側壁 8a、 8bに設けられた両方のリンク軸 6、 6には、リ ンク軸 6の非円形形状に対応する非円形孔で揷着された第 2リンク部材 9の上端を連 結する軸受部材 21、 21が回転不可に取り付けられている。この軸受部材 21、 21は 連結部 21 aで連結されて一体に形成されている。この軸受部材 21、 21間には、軸部 材 22が架設され、前記第 2リンク部材 9の上端は、この軸部材 22に回動可能に取り 付けられている。即ち、第 2リンク部材 9の上端は、軸受部材 21、 21を介してリンク軸 6、 6に連結されている。 [0025] In addition, a first non-circular hole corresponding to the non-circular shape of the link shaft 6 is attached to both of the link shafts 6 and 6 provided on the side walls 8a and 8b of the first link member 8. 2 The bearing members 21 and 21 that connect the upper ends of the link members 9 are non-rotatably attached. The bearing members 21 and 21 are integrally formed by being connected by a connecting portion 21a. A shaft member 22 is installed between the bearing members 21 and 21, and the upper end of the second link member 9 is rotatably attached to the shaft member 22. That is, the upper end of the second link member 9 is connected to the link shafts 6 and 6 via the bearing members 21 and 21.
[0026] このように並行する第 1リンク部材 8と第 2リンク部材 9、第 1リンク部材 8の下端を枢
着する軸 11、第 2リンク部材 9の下端を枢着する軸 12、および第 1リンク部材 8の上端 と第 2リンク部材 9を連結するリンク軸 6とは、四節リンク機構 5を構成し、この四節リン ク機構 5がアーム 3を構成する。 [0026] The first link member 8, the second link member 9, and the lower end of the first link member 8 that are parallel to each other are pivoted. The shaft 11 that attaches, the shaft 12 that pivots the lower end of the second link member 9, and the link shaft 6 that connects the upper end of the first link member 8 and the second link member 9 constitute a four-bar linkage mechanism 5. The four-bar linkage mechanism 5 constitutes the arm 3.
そして、第 2リンク部材 9の上部と第 1リンク部材 8の下部との間に引張ばね 7が張設 される。引張ばね 7の上端は、第 2リンク部材 9の上端に設けた軸部材 22に取り付け る力、、または、係止部材 23を設けこれに取り付けるようにしてもよい。図 2、図 3、図 4 および図 8には、軸部材 22に取付けた場合が示され、図 6および図 7には、係止部材 23に取付けた場合が示されている。また、引張ばね 7の下端は、本例では第 1リンク 部材 8の下部に取付部 24を設け、これに取り付けている力 S、これは軸 11であってもよ い。この引張ばね 7は、前述した第 1リンク部材 8と第 2リンク部材 9との間のスペース に配置されている。本例では引張ばね 7を 2本張設した場合を示している。これにより 第 1リンク部材 8と第 2リンク部材 9は、板状体で形成され、引張ばね 7は、この第 1リン ク部材 8と第 2リンク部材 9との間のスペースに内蔵されているので、リンク機構 5で構 成するアーム 3の厚さを薄くしてスリムにすることができるし、引張ばね 7は、第 1およ び第 2リンク部材 8、 9に保護され、他の部材への干渉もしないし、他の部材からの干 渉も防止される。 A tension spring 7 is stretched between the upper part of the second link member 9 and the lower part of the first link member 8. The upper end of the tension spring 7 may be attached to the force attached to the shaft member 22 provided at the upper end of the second link member 9 or the locking member 23. 2, FIG. 3, FIG. 4 and FIG. 8 show the case where the shaft member 22 is attached, and FIGS. 6 and 7 show the case where the shaft member 22 is attached. Further, the lower end of the tension spring 7 is provided with a mounting portion 24 in the lower part of the first link member 8 in this example, and the force S attached to this mounting portion 24 may be the shaft 11. The tension spring 7 is disposed in the space between the first link member 8 and the second link member 9 described above. In this example, two tension springs 7 are stretched. As a result, the first link member 8 and the second link member 9 are formed of a plate-like body, and the tension spring 7 is built in the space between the first link member 8 and the second link member 9. Therefore, the thickness of the arm 3 formed by the link mechanism 5 can be reduced and slimmed, and the tension spring 7 is protected by the first and second link members 8 and 9 and other members. Interference from other parts is also prevented.
[0027] 引張ばね 7は、主に表示パネル 1の重量による回転モーメントに対抗してバランスさ せるものであるので、表示パネル 1の重量による回転モーメントに対応させて引張ば ね 7のばね力および本数等を設定し、軽い力で表示パネル 1の高さの調整ができ、 操作性を良くすると共にバランス特性を最適とする。 [0027] Since the tension spring 7 is mainly balanced against the rotational moment due to the weight of the display panel 1, the spring force of the tension spring 7 and the tension spring 7 corresponding to the rotational moment due to the weight of the display panel 1 are adjusted. By setting the number, etc., the height of the display panel 1 can be adjusted with light force, improving operability and optimizing the balance characteristics.
図 11はアーム角度の変位(deg)における表示パネルを乗せた場合の重量モーメ ント Mwとアームに組み込むばね反力より発生する釣り合い(バランス)のばねモーメ ント Msを表す。 Fig. 11 shows the weight moment Mw when the display panel is placed at the arm angle displacement (deg) and the balance spring moment Ms generated by the spring reaction force built into the arm.
ばねモーメント Msは、表示パネル重量モーメント Mwに近似するほど作動範囲に おけるバランス特性が向上し、操作性が良好となり、軽い力で表示パネルの高さ調整 が可能となる。従って、引張ばね 7は、前記図 11に示すようなばねモーメント Msとな るように設定するのが好ましい。 The closer the spring moment Ms is to the display panel weight moment Mw, the better the balance characteristics in the operating range, the better the operability, and the lower the display panel height can be adjusted. Therefore, the tension spring 7 is preferably set so as to have a spring moment Ms as shown in FIG.
[0028] なお、表示パネル 1の重量による回転モーメントに対抗するばねとして、前記実施
の形態では、引張ばね 7の場合を示した力 これは他のばねでもよい。例えば、圧縮 ばね、皿ばね、輪ばね等を例示できる。 [0028] It should be noted that, as the spring that counteracts the rotational moment due to the weight of the display panel 1, the above-described implementation is performed. In the form of the force shown in the case of the tension spring 7, this may be another spring. For example, a compression spring, a disc spring, a ring spring, etc. can be illustrated.
図 14は、圧縮ばね 7aを使用した場合の側面説明図である。この圧縮ばね 7aの場 合は、圧縮ばね 7aの下端を第 2リンク部材 9の下端に連結し、圧縮ばね 7aの上端を 第 1リンク部材 8の上端に連結する。これによりアーム 3 (リンク部材 8、 9)が下向き(表 示パネル 1の高さを降下させる方向)に回動する場合には、圧縮ばね 7aが圧縮され、 その反発力(ばね力)が増加して表示パネルの重量による回転モーメントに対抗して ノ ランスさせる。矢印は圧縮ばねの付勢方向を示している。 FIG. 14 is an explanatory side view when the compression spring 7a is used. In the case of the compression spring 7a, the lower end of the compression spring 7a is connected to the lower end of the second link member 9, and the upper end of the compression spring 7a is connected to the upper end of the first link member 8. As a result, when the arm 3 (link members 8 and 9) rotates downward (in the direction of lowering the height of the display panel 1), the compression spring 7a is compressed and its repulsive force (spring force) increases. To counter the rotational moment due to the weight of the display panel. The arrow indicates the biasing direction of the compression spring.
また、皿ばねや輪ばねは、複数の皿ばねや輪ばねを積層状に重ね合わせて配列 し、これを前記圧縮ばねと同様に使用する。この皿ばねや輪ばねの場合には、皿ば ねや輪ばねを重ね合わせて配列した状態を保持させる補助具が必要となる。 In addition, a disc spring or a ring spring is formed by stacking a plurality of disc springs or ring springs in a stacked manner, and this is used in the same manner as the compression spring. In the case of this disc spring or ring spring, an auxiliary tool is required to maintain the state in which the disc springs and ring springs are arranged in an overlapping manner.
[0029] 次に、前記実施の形態に示す表示パネル支持装置の作用を説明する。 Next, the operation of the display panel support device shown in the embodiment will be described.
アーム 3を構成するリンク機構 5の第 1リンク部材 8および第 2リンク部材 9は、下端が 基台 2のブラケット 10に、軸 11、 12で回動可能に枢着され、第 2リンク部材 9の上端 は、第 1リンク部材 8の上端に設けたリンク軸 6に、軸受部材 21を介して軸部材 22で 連結され、第 1リンク部材 8の上端のリンク軸 6には、フリクション機構 15を介在して表 示パネル取付用フレーム 4が回動可能に取り付けられ、この表示パネル取付用フレ ーム 4には表示パネル 1が取り付けられる。そして、第 2リンク部材 9の上部と第 1リンク 部材 8の下部との間には、引張ばね 7が張設されている。 The first link member 8 and the second link member 9 of the link mechanism 5 constituting the arm 3 are pivotally attached to the bracket 10 of the base 2 so that the lower end of the first link member 8 and the second link member 9 can rotate about the shafts 11 and 12. The upper end of the first link member 8 is connected to a link shaft 6 provided at the upper end of the first link member 8 by a shaft member 22 via a bearing member 21, and a friction mechanism 15 is connected to the link shaft 6 at the upper end of the first link member 8. The display panel mounting frame 4 is pivotably mounted through the display panel mounting frame 4, and the display panel 1 is mounted on the display panel mounting frame 4. A tension spring 7 is stretched between the upper part of the second link member 9 and the lower part of the first link member 8.
従って、表示パネル取付用フレーム 4に取り付けられた表示パネル 1は、図 2に示 すようにリンク機構 5で構成するアーム 3を、第 1および第 2リンク部材 8、 9の軸 11、 1 2を中心に回動することで上下動でき、高さの調整ができる。この高さの調整をすると 、リンク機構 5の引張ばね 7が、主に表示パネル 1の重量による回転モーメントに対抗 してバランスさせるので、軽い力で上下動でき、その軽い力(外力)を取り除くとその 位置で停止(バランス静止)する。即ち、フリーストップする。要するに、軽い力で表示 パネルの高さ調整ができる。この表示パネル 1の高さの調整では、アーム 3がリンク機 構 5で構成されて!/、るので、表示パネル 1の傾斜角は変化しな!/、。 Accordingly, the display panel 1 attached to the display panel mounting frame 4 has the arm 3 constituted by the link mechanism 5 as shown in FIG. 2 and the shafts 11 and 1 2 of the first and second link members 8 and 9. It can be moved up and down by rotating around the center, and the height can be adjusted. When this height is adjusted, the tension spring 7 of the link mechanism 5 balances against the rotational moment mainly due to the weight of the display panel 1, so it can move up and down with a light force and remove the light force (external force). And stop at that position (balanced still). That is, the free stop is performed. In short, the height of the display panel can be adjusted with a light force. In this adjustment of the height of the display panel 1, the arm 3 is composed of the link mechanism 5! /, So the tilt angle of the display panel 1 does not change! /.
[0030] また、表示パネル 1は、図 3に示すように表示パネル取付用フレーム 4をリンク軸 6を
中心に回動することで、傾斜角の調整ができる。この表示パネル取付用フレーム 4は 、フリクション機構 15を介在してリンク軸 6に取り付けられているので、このフリクション 機構 15の抵抗力(摩擦抵抗)以上の力を加えることで回動でき傾斜角の調整ができ 、その外力を除くとフリクション機構 15の抵抗力(摩擦抵抗)でその位置に停止し、そ の姿勢を保持する。 In addition, the display panel 1 has a display panel mounting frame 4 and a link shaft 6 as shown in FIG. The tilt angle can be adjusted by pivoting to the center. The display panel mounting frame 4 is attached to the link shaft 6 with a friction mechanism 15 interposed therebetween. Therefore, the display panel mounting frame 4 can be rotated by applying a force greater than the resistance force (friction resistance) of the friction mechanism 15. If the external force is removed, it can be adjusted and stopped at that position by the resistance force (friction resistance) of the friction mechanism 15, and the posture is maintained.
[0031] この時の表示パネル 1の傾斜角の調整範囲は、係止板 19がばね 20に押圧されて ストッパ板 18の切欠 18aに位置するので、表示パネル取付用フレーム 4の作動範囲 が規制され、調整(作動)範囲は、切欠 18aの長さの範囲内である。しかし、係止板 1 9をばね 20に抗して摺動させ、ストツバ板 18の切欠 18aより外すと表示パネル取付用 フレーム 4の作動範囲が広くなり図 4に示すように折り畳みも可能となる。 [0031] At this time, the adjustment range of the inclination angle of the display panel 1 is restricted by the operating range of the display panel mounting frame 4 because the locking plate 19 is pressed by the spring 20 and is positioned in the notch 18a of the stopper plate 18. The adjustment (operation) range is within the length of the notch 18a. However, if the locking plate 19 is slid against the spring 20 and is removed from the notch 18a of the staggered plate 18, the operating range of the display panel mounting frame 4 is widened and can be folded as shown in FIG. .
[0032] 即ち、表示パネル取付用フレーム 4を上記の状態にして図 2の矢印 Xの方向に回動 し、また、リンク機構 5で構成するアーム 3を図 2の矢印 Y方向に回動することによって 、図 4に示すように折り畳むことが可能である。図 12には表示パネル取付用フレーム 4を水平位置まで回動した様子が示され、図 13には表示パネル取付用フレーム 4を 更に回動し、アーム 3も回動し折り畳んだ様子が示されており、折り畳みできる様子が 良く理解できる。 That is, the display panel mounting frame 4 is rotated in the direction of arrow X in FIG. 2 with the display panel mounting frame 4 in the above state, and the arm 3 constituted by the link mechanism 5 is rotated in the direction of arrow Y in FIG. Therefore, it can be folded as shown in FIG. 12 shows the state where the display panel mounting frame 4 is rotated to the horizontal position, and FIG. 13 shows the state where the display panel mounting frame 4 is further rotated and the arm 3 is also rotated and folded. You can understand how you can fold it.
[0033] また、表示パネル取付用フレーム 4は、表示パネル 1を取付可能なべサ(プレート) とベースを有し、べサは表示パネル 1を横長向き及び縦長向きに変換可能なピボット 機構、ベースは表示パネル 1を左右自在の向きに回転できるスィーベル機構を備え る力 これらは従来公知なので、詳細な説明は省略する。 [0033] The display panel mounting frame 4 has a besa (plate) to which the display panel 1 can be mounted and a base, and the besa is a pivot mechanism and a base that can convert the display panel 1 into a horizontal orientation and a vertical orientation. Is a force provided with a swivel mechanism that can rotate the display panel 1 in a left-right direction.
また、基台 2も回転可能となっているのが好ましい。この基台 2を回転可能とする構 成も従来公知なものを採用し得る。 The base 2 is also preferably rotatable. A conventionally well-known structure can be adopted to make the base 2 rotatable.
[0034] なお、前記実施の形態は、この発明を制限するものではなぐこの発明は要旨を逸 脱しない範囲において種々の変更が許される。例えば、リンク機構 5は他のリンク機 構であってもよいことはもちろんであるし、引張ばね 7に代えて他のばねとすることも できる。 It should be noted that the above embodiment is not intended to limit the present invention, and various modifications are allowed within the scope of the present invention. For example, the link mechanism 5 may be another link mechanism, and may be another spring instead of the tension spring 7.
