Description

本発明は、液晶ディスプレイ（モニター）等の表示装置を被昇降体として上下方向の任意の位置に静止保持できる昇降装置に関する。 The present invention relates to an elevating device capable of holding a display device such as a liquid crystal display (monitor) stationary at an arbitrary position in the vertical direction as an elevating body.

液晶ディスプレイ（モニター）等の表示装置、例えば大型サイズの表示装置を上下方向の任意の位置に静止保持できる昇降装置が提案されている（特許文献１、２）。 Display devices such as liquid crystal displays (monitors), for example, elevating devices capable of stationaryly holding a large-sized display device at an arbitrary position in the vertical direction have been proposed (Patent Documents 1 and 2).

これらの昇降装置は、取付ブラケットに取り付けられた表示装置等の被昇降体を上下方向の下限のロック位置と上限のロック位置にロック機構によりロック保持可能としている。例えば下限のロック位置にロックされている被昇降体を操作者が上方に押し上げると、ロック機構のロックが解除され、ばね部のばね力に付勢されて軽い押し上げ力で上方に向けて移動する。そして、操作者が被昇降体の押し上げを停止すると、摩擦力を利用したフリクション機構の作用でその位置に停止する。 In these elevating devices, an elevating body such as a display device attached to a mounting bracket can be locked and held at a lower limit lock position and an upper limit lock position in the vertical direction by a lock mechanism. For example, when the operator pushes the lifted body locked at the lower limit lock position upward, the lock mechanism is unlocked and is urged by the spring force of the spring part to move upward with a light pushing force. .. Then, when the operator stops pushing up the lifting body, the friction force is used to stop the lifted body at that position.

操作者が被昇降体を上下のロック位置間の任意の停止位置から上方又は下方のロック位置まで押し上げ又は押し下げると、ロック機構が動作して自動的に取付ブラケットがロック位置にロックされる。上限のロック位置において、被昇降体の自重でロック機構がロック解除されることがない。同様に、下限のロック位置において、ばね部のばね力でロック機構がロック解除されることがない。 When the operator pushes up or down the lifted body from an arbitrary stop position between the upper and lower lock positions to the upper or lower lock position, the lock mechanism operates and the mounting bracket is automatically locked to the lock position. At the upper limit lock position, the lock mechanism is not unlocked by the weight of the elevating body. Similarly, at the lower limit lock position, the lock mechanism is not unlocked by the spring force of the spring portion.

したがって、第１スライダー４０と被昇降体２は、取付ブラケット１００を介して一体に昇降する。 Therefore, the first slider 40 and the lifting body 2 move up and down integrally via the mounting bracket 100.

第１本体部４１の背壁部４４には、左右方向に沿って細長い矩形形状の開口窓５１が形成されている。開口窓５１は、開口上縁が頂壁部４２の下面と略一致して形成されている。開口窓５１には、後述する第２スライダー６０の係合凸部７３が前後方向に沿って移動可能に嵌まり込む。第１スライダー４０がベース部材１０の支柱１２内を昇降する際、開口窓５１は第１ロック凹部１９、第２ロック凹部２０に臨むようになっている。 The back wall portion 44 of the first main body portion 41 is formed with an elongated rectangular opening window 51 along the left-right direction. The opening window 51 is formed so that the upper edge of the opening substantially coincides with the lower surface of the top wall portion 42. The engaging convex portion 73 of the second slider 60, which will be described later, is fitted into the opening window 51 so as to be movable along the front-rear direction. When the first slider 40 moves up and down in the support column 12 of the base member 10, the opening window 51 faces the first lock recess 19 and the second lock recess 20.

第１本体部４１の頂壁部４２の下面には、ガイド孔４７の左右に、一対のガイドレール５２が前後方向に沿って形成されている。一対のガイドレール５２には、後述する第２スライダー６０の左右に設けた一対のガイド溝７１、７２がスライド自在に嵌合する。第１本体部４１の空所に形成されている内部５３内には、後述する第２スライダー６０が前後方向にスライド可能に収容され、さらに第３スライダー８０が昇降方向に移動可能に収容される。 A pair of guide rails 52 are formed on the left and right sides of the guide holes 47 along the front-rear direction on the lower surface of the top wall portion 42 of the first main body portion 41. A pair of guide grooves 71 and 72 provided on the left and right sides of the second slider 60, which will be described later, are slidably fitted to the pair of guide rails 52. A second slider 60, which will be described later, is housed slidably in the front-rear direction, and a third slider 80 is housed so as to be movable in the up-and-down direction in the inner 53 formed in the empty space of the first main body 41. ..

It is sandwiched between and held under pressure. Therefore, the first slider that receives the load W of the lifting body 2 and the second slider 60 move integrally along the vertical direction in the vertical direction.

第２スライダー６０の下面と第３スライダー８０の上面との接触面は傾斜面で接触し、第３スライダー８０に昇降方向上向きのばね力（Ｆ１、Ｆ２）が作用すると、前記接触面で生じる分力が第２スライダー６０を前後方向の後方に向けて作用する。 The contact surface between the lower surface of the second slider 60 and the upper surface of the third slider 80 is in contact with each other on an inclined surface, and when a spring force (F1, F2) upward in the ascending / descending direction acts on the third slider 80, the amount generated at the contact surface. The force acts on the second slider 60 toward the rear in the front-rear direction.

移動部材である第２スライダー６０は、上面が略矩形形状に形成された第２本体部６１を有する。第２本体部６１は、第１スライダー４０の第１本体４１内の内部５３内に左右方向においてガタなく収容される長さに形成され、前後方向に対しては移動可能なクリアランスを有する前後方向の長さに形成されている。第２本体部６１の前後方向の長さは、第３スライダー８０の傾斜台部８１の前後方向の長さよりも短く形成されている。 The second slider 60, which is a moving member, has a second main body portion 61 whose upper surface is formed in a substantially rectangular shape. The second main body 61 is formed in a length that is accommodated in the inner 53 of the first main body 41 of the first slider 40 without play in the left-right direction, and has a clearance that can be moved in the front-rear direction. It is formed to the length of. The length of the second main body 61 in the front-rear direction is shorter than the length of the tilting base 81 of the third slider 80 in the front-rear direction.

第２本体部６１は、平坦な上端の上壁部６２と、背面側ＲＳの背壁部６３と、左右の側壁部６４、６５と、前面側ＦＳの前壁部６６と、傾斜面の底壁部６７とを有する。 The second main body portion 61 includes a flat upper end upper wall portion 62, a back wall portion 63 of the back side RS, left and right side wall portions 64 and 65, a front wall portion 66 of the front side FS, and a bottom of an inclined surface.

上壁部６２には、前面側ＦＳを開口するＵ字形状の切欠き部６８が形成されている。切欠き部６８は、半径Ｒの円弧部６９と、左右方向の幅が２Ｒの開口部７０を有する。第３スライダー８０のスライド筒部８２の外径は、切欠き部６８の開口部７０の開口幅２Ｒと等しく形成される。第２スライダー６０の切欠き部６８は、第３スライダー８０のスライド筒部８２に、前後方向に沿ってスライド自在に嵌合する。 The upper wall portion 62 is formed with a U-shaped notch portion 68 that opens the front side FS. The notch portion 68 has an arc portion 69 having a radius R and an opening 70 having a width of 2R in the left-right direction. The outer diameter of the slide cylinder portion 82 of the third slider 80 is formed to be equal to the opening width 2R of the opening 70 of the notch portion 68. The notch portion 68 of the second slider 60 is slidably fitted to the slide cylinder portion 82 of the third slider 80 along the front-rear direction.

上壁部６２には、切欠き部６８の左右両側に、前後方向に沿って延びるガイド溝７１、７２が形成される。ガイド溝７１、７２は、第１スライダー４０内に配置された状態で、図４（ｂ）に示す一対のガイドレール５２に嵌まり込み、第２スライダー６０の前後方向のスムーズな移動を保証する。 The upper wall portion 62 is formed with guide grooves 71 and 72 extending in the front-rear direction on both the left and right sides of the notch portion 68. The guide grooves 71 and 72 are fitted into the pair of guide rails 52 shown in FIG. 4B while being arranged in the first slider 40 to ensure smooth movement of the second slider 60 in the front-rear direction. ..

背壁部６３には、台形形状の係合凸部７３が前後方向後方に向けて突出する。係合凸部７３は、上下の対向する２側面の対向幅と、左右の対向する２側面の対向幅が前後方向の後方に向うに従って狭くなるテーパー形状に形成されている。係合凸部７３の左右方向の幅は長いことが望ましく、第１スライダー４０の開口窓５１にスライド自在に入り込む長さに設定されている。係合凸部７３は、背壁部６３に交換可能に装着される。 A trapezoidal engaging convex portion 73 projects rearward in the front-rear direction from the back wall portion 63. The engaging convex portion 73 is formed in a tapered shape in which the facing widths of the two opposing side surfaces on the upper and lower sides and the facing widths of the two facing side surfaces on the left and right sides become narrower toward the rear in the front-rear direction. It is desirable that the width of the engaging convex portion 73 in the left-right direction is long, and the width is set so as to slidably enter the opening window 51 of the first slider 40. The engaging convex portion 73 is replaceably attached to the back wall portion 63.

また、第２スライダー６０の係合凸部７３の前後方向後方に向けて突出する突出長さは、図５（ｃ）に示すように、第２スライダー６０の第２本体部６１が第１スライダー４０の背壁部４４に当接した状態（第２スライダー６０が前後方向後方に最も移動した状態）において、背壁部４４に形成された開口窓５１を貫通し、さらに、ベース部材１０の支柱１２の背面壁１３に形成した第１ロック凹部１９（第２ロック凹部２０）の底面に達するまでの長さに設定している。 Further, as shown in FIG. 5 (c), the second main body 61 of the second slider 60 has the first slider so that the protruding length of the engaging convex portion 73 of the second slider 60 projects rearward in the front-rear direction. In a state of being in contact with the back wall portion 44 of 40 (a state in which the second slider 60 is most moved rearward in the front-rear direction), it penetrates the opening window 51 formed in the back wall portion 44, and further, a support of the base member 10. The length is set to reach the bottom surface of the first lock recess 19 (second lock recess 20) formed in the back wall 13 of the twelve.

さらに、第２本体部６１の前後方向の長さは、第１スライダー４０の内部５３内において、図５（ｄ）に示すように、係合凸部７３の先端面７３ａが図５（ｃ）に示す位置から支柱１２の背面壁１３に当接する位置まで、少なくとも前後方向前方に後退できる長さに設定できれば良い。本実施形態では、第２スライダー６０を第１スライダー４０の内部５３内に装着できるようにするために、第２本体部６１と係合凸部７３の長さも含めて内部５３の前後方向の長さよりも若干短く設定している。 Further, as for the length of the second main body 61 in the front-rear direction, as shown in FIG. 5 (d), the tip surface 73a of the engaging convex portion 73 is shown in FIG. 5 (c) inside the first slider 40. It suffices if the length can be set so as to be able to retract at least forward in the front-rear direction from the position shown in In the present embodiment, in order to allow the second slider 60 to be mounted inside the inner 53 of the first slider 40, the length of the inner 53 in the front-rear direction including the length of the second main body 61 and the engaging convex portion 73 is included. It is set slightly shorter than the slider.

第２本体部６１の係合凸部７３の先端面７３ａは、部分的に複数の窪み部（凹部）７６が形成される。図５（ｄ）に示すように、係合凸部７３が支柱１２の背面壁１３にばね力（Ｆ１、Ｆ２）の分力で加圧接触している状態において、窪み部７６の存在で先端面７３ａが背面壁１３に接触する接触面積が減少するが、逆に接触している部分に加圧力が集中し、摩擦力が増加する。このため、第１ロック凹部１９と第２ロック凹部２０の間の任意の位置に、摩擦力で取付ブラケット１００に取り付けられた被昇降体２を停止させる際、強い摩擦力で停止保持することができる。なお、係合凸部７３の先端面７３ａには、凹部ではなく凸部を設けても良い。 A plurality of recesses (recesses) 76 are partially formed on the tip surface 73a of the engaging protrusions 73 of the second main body 61. As shown in FIG. 5D, in a state where the engaging convex portion 73 is in pressure contact with the back wall 13 of the support column 12 by the component force of the spring force (F1, F2), the tip is in the presence of the recessed portion 76. The contact area where the surface 73a contacts the back wall 13 decreases, but on the contrary, the pressing force concentrates on the contacted portion and the frictional force increases. Therefore, when the lifting body 2 attached to the mounting bracket 100 is stopped by a frictional force at an arbitrary position between the first lock recess 19 and the second lock recess 20, it can be stopped and held by a strong frictional force. it can. The tip surface 73a of the engaging convex portion 73 may be provided with a convex portion instead of a concave portion.

第２本体部６１の背壁部６３と左右の側壁部６４、６５にも、窪み部７６をそれぞれ複数形成している。これは、第１スライダー４０の第１本体４１の内周壁面に対し、背壁部６３と左右の側壁部６４、６５を高い摩擦力で加圧接触させるためである。これにより、第１スライダー４０と第２スライダー６０との前後方向及び昇降方向における相対的なガタつきを防止している。左右の側壁部６４、６５に形成される窪み部７６は、左右方向に沿って少なくとも例えばガイド溝７１、７２まで達している。 A plurality of recesses 76 are also formed in the back wall portion 63 of the second main body portion 61 and the left and right side wall portions 64 and 65, respectively. This is because the back wall portion 63 and the left and right side wall portions 64, 65 are brought into pressure contact with the inner peripheral wall surface of the first main body 41 of the first slider 40 with a high frictional force. As a result, the relative rattling of the first slider 40 and the second slider 60 in the front-rear direction and the elevating direction is prevented. The recessed portions 76 formed in the left and right side wall portions 64 and 65 reach at least the guide grooves 71 and 72 along the left and right directions.

底壁部６７は、前後方向の前方に向けて上向きに傾斜した傾斜面に形成される。即ち、背壁部６３の下端が前壁部６１の下端よりも昇降方向の下方に位置し、背壁部６３の下端から前壁部６１の下端に向けて傾斜した傾斜面に底壁部６７が形成されている。底壁部６７の傾斜面は第３スライダー８０の傾斜台部８１の傾斜面と平行に形成されている。 The bottom wall portion 67 is formed on an inclined surface that is inclined upward toward the front in the front-rear direction. That is, the lower end of the back wall portion 63 is located below the lower end of the front wall portion 61 in the ascending / descending direction, and the bottom wall portion 67 is on an inclined surface inclined from the lower end of the back wall portion 63 toward the lower end of the front wall portion 61. Is formed. The inclined surface of the bottom wall portion 67 is formed parallel to the inclined surface of the inclined base portion 81 of the third slider 80.

底壁部６７には、切欠き部６８の左右両側に、前後方向に沿ってガイド溝７４、７５が形成されている。ガイド溝７４、７５は、第３スライダー８０の上壁部８３に第２スライダー６０の底壁部６７を当接させた際に、上壁部８３に形成したガイドレール８４に嵌まり込む。これにより、第２スライダー６０と第３スライダー８０が前後方向に沿ってスムーズな相対移動が保証される。 Guide grooves 74 and 75 are formed in the bottom wall portion 67 along the front-rear direction on both the left and right sides of the notch portion 68. The guide grooves 74 and 75 fit into the guide rail 84 formed on the upper wall portion 83 when the bottom wall portion 67 of the second slider 60 is brought into contact with the upper wall portion 83 of the third slider 80. As a result, the second slider 60 and the third slider 80 are guaranteed to move smoothly in the front-rear direction.

本実施形態において、支柱１２と、第１ばね３５（ばね力Ｆ１）と、第２ばね３６（ばね力Ｆ２）と、第１スライダー４０と、第２スライダー６０と、第３スライダー８０により、被昇降体２を昇降方向の任意の位置に摩擦力を利用して停止保持するフリクション機構を構成している。 In the present embodiment, the support is covered by the support column 12, the first spring 35 (spring force F1), the second spring 36 (spring force F2), the first slider 40, the second slider 60, and the third slider 80. A friction mechanism is configured to stop and hold the elevating body 2 at an arbitrary position in the elevating direction by using frictional force.

また、支柱１２の第１ロック凹部１９と第２ロック凹部２０と、第１ばね３５と、第２ばね３６と、第１スライダー４０と、第２スライダー６０と、第３スライダー８０により、被昇降体２を第１ロック凹部１９または第２ロック凹部２０に固定するロック機構を構成する。 Further, the support is raised and lowered by the first lock recess 19, the second lock recess 20, the first spring 35, the second spring 36, the first slider 40, the second slider 60, and the third slider 80. A lock mechanism for fixing the body 2 to the first lock recess 19 or the second lock recess 20 is configured.

即ち、本実施形態では、フリクション機構とロック機構は兼用され、第２スライダー６０の係合凸部７３が第１ロック凹部１９または第２ロック凹部２０に係合する場合には、ロック機構として作用し、支柱１２の背面壁１３に加圧接触する場合にはフリクション機構として作用する。 That is, in the present embodiment, the friction mechanism and the lock mechanism are used in combination, and when the engaging protrusion 73 of the second slider 60 engages with the first lock recess 19 or the second lock recess 20, it acts as a lock mechanism. However, when it comes into pressure contact with the back wall 13 of the support column 12, it acts as a friction mechanism.

図５（ｃ）はロック機構として作用している場合を示し、図５（ｄ）はフリクション機構として作用している場合を示す。 FIG. 5C shows a case where it acts as a locking mechanism, and FIG. 5D shows a case where it acts as a friction mechanism.

図５（ｃ）に示すロック状態において、第３スライダー８０には第１ばね３５のばね力Ｆ１と第２ばね３６のばね力Ｆ２の昇降方向上方に向けたばね力が加わる。傾斜面同士の接触で第２スライダー６０には前後方向後方へ向けた分力（以下、後方分力ＦＲと称す）が作用する。 In the locked state shown in FIG. 5 (c), the spring force F1 of the first spring 35 and the spring force F2 of the second spring 36 are applied to the third slider 80 in the ascending / descending direction. Due to the contact between the inclined surfaces, a component force (hereinafter, referred to as a rear component force FR) directed to the rear in the front-rear direction acts on the second slider 60.

後方分力ＦＲが作用する第２スライダー６０は、第２本体部６１の背壁部６３が第１スライダー４０の背壁部４４の内面に当接する第１スライド位置まで前後方向の後方に向けてスライド移動する。第１スライド位置において、第２スライダー６０の係合凸部７３は、第１スライダー４０の開口窓５１を貫通して、支柱１２の例えば第１ロック凹部１９内まで差し込まれて係合する。ロック位置での係合状態が解除されるためには、例えば、第１スライダー４０に昇降方向下方に押し下げ力Ｆ０を加える。押し下げ力Ｆ０は、第２スライダー６０に作用し、係合凸部７３に伝達される。係合凸部７３には、第１ロック凹部１９との傾斜面同士の加圧接触により、前後方向の前方に向けた分力（以下、前方分力ＦＦと称す）が作用する。 The second slider 60 on which the rear component force FR acts is directed backward in the front-rear direction to the first slide position where the back wall portion 63 of the second main body portion 61 abuts on the inner surface of the back wall portion 44 of the first slider 40. Slide to move. At the first slide position, the engaging convex portion 73 of the second slider 60 penetrates the opening window 51 of the first slider 40 and is inserted into, for example, the first lock recess 19 of the support column 12 to engage. In order to release the engaged state at the locked position, for example, a pushing force F0 is applied downward in the ascending / descending direction to the first slider 40. The pushing force F0 acts on the second slider 60 and is transmitted to the engaging convex portion 73. A component force toward the front in the front-rear direction (hereinafter, referred to as a front component force FF) acts on the engaging convex portion 73 by pressure contact between the inclined surfaces with the first lock recess 19.

前方分力ＦＦが後方分力ＦＲよりも大きい（ＦＦ＞ＦＲ）場合には、第１スライダー４０が昇降方向の下方に向けて移動しながら第２スライダー６０が前後方向の前方に向けて移動し、係合凸部７３が第１ロック凹部１９との係合から脱する第２スライド位置まで移動する。そうすると、前方分力ＦＦがゼロとなり、支柱１２の背壁面１３の支柱壁部の内壁面である内壁面に係合凸部７３が後方分力ＦＲで加圧接触する。 When the front component force FF is larger than the rear component force FR (FF> FR), the first slider 40 moves downward in the ascending / descending direction, and the second slider 60 moves forward in the front-rear direction. , The engaging convex portion 73 moves to the second slide position where the engaging convex portion 73 disengages from the engagement with the first lock concave portion 19. Then, the front component force FF becomes zero, and the engaging convex portion 73 comes into pressure contact with the inner wall surface of the support column wall portion of the back wall surface 13 of the support column 12 by the rear component force FR.

後方分力ＦＲにより係合凸部７３と背壁面１３の内壁面が接触して生じる摩擦力Ｆ３によって、押し下げ力Ｆ０を解除した位置で被昇降体２を静止状態に保持する。 The lifting body 2 is held in a stationary state at a position where the pushing force F0 is released by the frictional force F3 generated by the contact between the engaging convex portion 73 and the inner wall surface of the back wall surface 13 due to the rear component force FR.

一方、図５（ｄ）に示す被昇降体２の静止保持状態から昇降方向の上方に向けて押し上げ力Ｆ４を第１スライダー４０に作用すると、第１スライダー４０は昇降方向の上方に向けて移動し、係合凸部７３がクリック嵌合部である第１ロック凹部１９に達すると、後方分力ＦＲによりクリック感を有して第１ロック凹部１９内に嵌まり込む。 On the other hand, when the pushing force F4 is applied to the first slider 40 in the ascending / descending direction from the stationary holding state of the elevating body 2 shown in FIG. 5D, the first slider 40 moves upward in the ascending / descending direction. Then, when the engaging convex portion 73 reaches the first lock recess 19 which is the click fitting portion, the engaging convex portion 73 is fitted into the first lock recess 19 with a click feeling due to the rear component force FR.

上記した実施形態による昇降装置の動作を図６〜図８を参照して説明する。なお、図６〜図８は、図１に示す昇降装置１のＥ−Ｅ矢視断面図を示し、第１スライダー４０は図３（ａ）に示すＥ−Ｅ矢視断面を示し、第２スライダー６０は図４（ｂ）のＥ−Ｅ矢視断面を示し、第３スライダー８０は図５（ａ）のＥ−Ｅ矢視断面を示す。 The operation of the elevating device according to the above-described embodiment will be described with reference to FIGS. 6 to 8. 6 to 8 show a cross-sectional view taken along the line EE of the elevating device 1 shown in FIG. 1, and the first slider 40 shows a cross-sectional view taken along the line EE shown in FIG. 3A. The slider 60 shows the cross section taken along the line EE of FIG. 4 (b), and the third slider 80 shows the cross section taken along the line EE of FIG. 5 (a).

図６は昇降装置１の縦断面図で、取付ブラケット１００が上限のロック位置にロックされた状態を示し、図７は取付ブラケット１００が下限のロック位置にロックされた状態を示し、図８は取付ブラケット１００が上限のロック位置と下限のロック位置の間に摩擦保持された状態を示す。 FIG. 6 is a vertical cross-sectional view of the lifting device 1, showing a state in which the mounting bracket 100 is locked at the upper limit lock position, FIG. 7 shows a state in which the mounting bracket 100 is locked at the lower limit lock position, and FIG. Indicates a state in which the mounting bracket 100 is frictionally held between the upper limit lock position and the lower limit lock position.

図６に示すように、昇降装置１は、クリック嵌合形式のロック機構の作動により、第２スライダー６０が後方分力ＦＲにより第１スライド位置まで移動し、第１ロック凹部１９に係合凸部７３が係合する。第１ばね３５と第２ばね３６が長く伸びている状態にある。この状態におけるばね力は昇降範囲内で最も小さい。しかし、被昇降体２の荷重Ｗによって発生する前方分力ＦＦが、後方分力ＦＲを上回ってロックが解除されないように、第１ばね３５と第２ばね３６のばね力が設定されている。 As shown in FIG. 6, in the lifting device 1, the second slider 60 is moved to the first slide position by the rear component force FR by the operation of the click fitting type lock mechanism, and is engaged with the first lock recess 19. The portion 73 engages. The first spring 35 and the second spring 36 are in a long stretched state. The spring force in this state is the smallest within the elevating range. However, the spring forces of the first spring 35 and the second spring 36 are set so that the front component force FF generated by the load W of the lifting body 2 exceeds the rear component force FR and the lock is not released.

図６に示す昇降方向の下限位置に取付ブラケット１００をロックした場合、第１ばね３５と第２ばね３６は、昇降範囲内で最も縮んだ状態にある。この状態で、第１ばね３５のばね力Ｆ１と第２ばね３６のばね力Ｆ２により、荷重Ｗの被昇降体２を取り付けた取付ブラケット１００に対するロックの解除がなされないように、後方分力ＦＲと前方分力ＦＦが設定されている。 When the mounting bracket 100 is locked at the lower limit position in the elevating direction shown in FIG. 6, the first spring 35 and the second spring 36 are in the most contracted state within the elevating range. In this state, the rear component force FR is prevented from being unlocked by the spring force F1 of the first spring 35 and the spring force F2 of the second spring 36 with respect to the mounting bracket 100 to which the lifting body 2 having the load W is attached. And the forward component force FF is set.

取付ブラケット１００を昇降方向の上限位置から昇降方向の下方の任意の位置に停止させる場合、あるいは昇降方向の下限位置から昇降方向の上方の任意の位置に停止させる場合には、操作者が取付ブラケット１００に取り付けられた被昇降体２に手をかけて、昇降方向の下方又は上方に操作力Ｆ０またはＦ４を作用する。 When stopping the mounting bracket 100 from the upper limit position in the elevating direction to an arbitrary position below the elevating direction, or when stopping the mounting bracket 100 from the lower limit position in the elevating direction to an arbitrary position above the elevating direction, the operator attaches the mounting bracket. The operating force F0 or F4 is applied downward or upward in the elevating direction by putting a hand on the elevating body 2 attached to the 100.

ロック状態において、操作力Ｆ０またはＦ４が作用すると、第２スライダー６０に対し、前後方向の前方に作用している前方分力ＦＦが増加する。前方分力ＦＦの増加により、係合凸部７３は第１ロック凹部１９又は第２ロック凹部２０との係合を脱してロック解除される。さらに、操作力Ｆ０またはＦ４を作用し続けると、第２スライダー６０に後方分力ＦＲが付与された状態を維持して、第１スライダー４０と第２スライダー６０と第３スライダー８０が取付ブラケット１００を介して被昇降体２と共に、昇降方向の上方または下方に移動する。 When the operating force F0 or F4 acts in the locked state, the forward component force FF acting forward in the front-rear direction increases with respect to the second slider 60. As the front component force FF increases, the engaging convex portion 73 is disengaged from the first lock recess 19 or the second lock recess 20 and unlocked. Further, when the operating force F0 or F4 is continuously applied, the rear component FR is maintained on the second slider 60, and the first slider 40, the second slider 60, and the third slider 80 are attached to the mounting bracket 100. It moves upward or downward in the elevating direction together with the elevating body 2 via the above.

第２スライダー６０の係合凸部７３は、後方分力ＦＲにより、支柱１２の背面壁１３の内壁面に加圧接触し、昇降方向に摩擦力Ｆ３が発生している。操作力Ｆ０またはＦ４の作用で、第１スライダー４０に加わる昇降方向の上方または下方に作用する全荷重が摩擦力Ｆ３に等しくなると、支柱１２に対して被昇降体２が昇降方向の上方または下方に移動する。 The engaging convex portion 73 of the second slider 60 is in pressure contact with the inner wall surface of the back wall 13 of the support column 12 by the rear component force FR, and a frictional force F3 is generated in the elevating direction. When the total load applied to the first slider 40 in the ascending / descending direction becomes equal to the frictional force F3 due to the action of the operating force F0 or F4, the elevating body 2 moves upward or in the elevating direction with respect to the support column 12. Move to.

第１ロック凹部１９で位置決めされる上限のロック位置と、第２ロック凹部２０で位置決めされる下限のロック位置の間において、操作力Ｆ０またはＦ４の操作力を解除すると、摩擦力Ｆ３の作用により、その位置に第２スライダー６０が保持される。これにより、取付ブラケット１００に取り付けられている被昇降体２をその位置に停止保持することができる。 When the operating force of the operating force F0 or F4 is released between the upper limit lock position positioned in the first lock recess 19 and the lower limit lock position positioned in the second lock recess 20, the frictional force F3 acts. , The second slider 60 is held at that position. As a result, the lifting body 2 attached to the mounting bracket 100 can be stopped and held at that position.

本実施形態では、前記フリクション機構と前記ロック機構を兼用することで、大幅に部品点数を削減することができる。このため、組み立て工数、コストの低減化を図ることができる。 In the present embodiment, the number of parts can be significantly reduced by using both the friction mechanism and the lock mechanism. Therefore, the assembly man-hours and costs can be reduced.

また、支柱１２の背面壁１３の内壁面は、第２スライダー６０の係合凸部７３の先端面７３ａとの接触で摩擦力Ｆ３が発生するので、適当な表面粗さに表面加工したり、摩擦部材を塗布したり貼り付けたりすることが良い。 Further, the inner wall surface of the back wall 13 of the support column 12 generates a frictional force F3 when it comes into contact with the tip surface 73a of the engaging convex portion 73 of the second slider 60, so that the surface can be surface-processed to an appropriate surface roughness. It is good to apply or attach a friction member.

また、ばね部４は、第１ばね３５と第２ばね３６の２本のばねを同軸上に配置することで、省スペース化を果たすことができ、複数のばねのばね力を集中して一か所に付与することができる。さらに、ばね力が異なる２本のばねを用いることで、全体のばね力を細かく設定することができる。 Further, the spring portion 4 can save space by arranging the two springs of the first spring 35 and the second spring 36 coaxially, and can concentrate the spring forces of the plurality of springs. Can be given to a place. Further, by using two springs having different spring forces, the total spring force can be finely set.

第２スライダー６０と第３スライダー８０の楔効果によって、係合凸部７３に対してロックを行うための力と、任意の位置で摩擦保持をおこなうための力である後方分力ＦＲを発生させているが、本発明はこれに限定されるものではない。要するに、昇降方向の上向きに作用するばね力により、係合凸部７３に後方分力ＦＲを発生させるものであれば良い。例えばパンダグラフ構造のリンク機構等を例示することができる。 The wedge effect of the second slider 60 and the third slider 80 generates a rear component FR, which is a force for locking the engaging convex portion 73 and a force for holding friction at an arbitrary position. However, the present invention is not limited to this. In short, any spring force acting upward in the elevating direction may generate a rear component force FR in the engaging convex portion 73. For example, a link mechanism having a panda graph structure can be exemplified.

第２実施形態
図９はフリクション機構兼ロック機構の第２実施形態を示す縦断面図を示す。 Second Embodiment FIG. 9 shows a vertical cross-sectional view showing a second embodiment of the friction mechanism / locking mechanism.

図９において、支柱１２内に昇降方向に沿ってスライド自在に配置される第１スライダー４００は、第１本体部４０１の内部４０２が空所に形成され、下面が開放され、頂面が頂壁部４０３により塞がれ、４側面が壁部により囲まれている。第１本体部４０１の背壁部４０４に開口窓４０５が形成されている。第１本体部４０１の内部４０２には、左右方向に延びる板部材で構成される４枚のリンク部材４０６〜４０９が第１〜第４連結部材４１０〜４１３で連結されるリンク機構４１４を構成する。前後方向の後端側に位置する移動部材である第４連結部材４１３には、図３に示す第２スライダー６０の係合凸部７３が取り付けられている。係合凸部７３は開口窓４０５を貫通可能としている。 In FIG. 9, in the first slider 400 slidably arranged in the support column 12 along the elevating direction, the inside 402 of the first main body portion 401 is formed in an empty space, the lower surface is opened, and the top surface is the top wall. It is closed by a portion 403, and four side surfaces are surrounded by a wall portion. An opening window 405 is formed in the back wall portion 404 of the first main body portion 401. The internal 402 of the first main body 401 constitutes a link mechanism 414 in which four link members 406 to 409 composed of plate members extending in the left-right direction are connected by the first to fourth connecting members 410 to 413. .. An engaging convex portion 73 of the second slider 60 shown in FIG. 3 is attached to the fourth connecting member 413, which is a moving member located on the rear end side in the front-rear direction. The engaging protrusion 73 is capable of penetrating the opening window 405.

第１本体部４０１の底面開口部には、板状のばね受け座４１５が第１本体部４０１内を昇降方向に沿って移動可能に配置される。ばね受け座４１５の上面には第３連結部材４１２が当接する。ばね受け座４１５の下面にはばね力Ｆ１の第１ばね（図示せず）と、ばね力Ｆ２の第２ばね（図示せず）が配置される。 A plate-shaped spring receiving seat 415 is movably arranged in the first main body 401 in the elevating direction in the bottom opening of the first main body 401. The third connecting member 412 comes into contact with the upper surface of the spring receiving seat 415. A first spring having a spring force F1 (not shown) and a second spring having a spring force F2 (not shown) are arranged on the lower surface of the spring receiving seat 415.

リンク機構４１４は、第１連結部材４１０が頂壁部４０３の下面に当接し、第２連結部材４１１が前壁部４１６の内面に当接する。ばね受け座４１５に対して昇降方向の上方に向けて作用するばね力（Ｆ１＋Ｆ２）は、第３連結部材４１２を介してリンク機構４１４に伝達される。 In the link mechanism 414, the first connecting member 410 abuts on the lower surface of the top wall portion 403, and the second connecting member 411 abuts on the inner surface of the front wall portion 416. The spring force (F1 + F2) acting upward in the elevating direction with respect to the spring receiving seat 415 is transmitted to the link mechanism 414 via the third connecting member 412.

ばね力（Ｆ１＋Ｆ２）の伝達により、第４連結部材４１３に取り付けた係合凸部７３が第１ロック凹部１９または第２ロック凹部２０内に差し込まれて係合し、または支柱１２の背面壁１３の内壁面に当接する。この場合、第２連結部材４１１には当接する前壁部４１６に対して前後方向の前方に向けた反力（−ＦＲ）が作用し、第４連結部材４１３には前後方向の後方に向う後方分力ＦＲが発生する。その結果、係合凸部７３が第１ロック凹部１９または第２ロック凹部２０内に差し込まれて係合し、あるいは、支柱１２の背面壁１３の内壁面に摩擦接触して摩擦力Ｆ４を発生させる。 By transmitting the spring force (F1 + F2), the engaging convex portion 73 attached to the fourth connecting member 413 is inserted into and engaged with the first lock recess 19 or the second lock recess 20, or the back wall 13 of the support column 12 It abuts on the inner wall surface of. In this case, a reaction force (-FR) directed forward in the front-rear direction acts on the front wall portion 416 that abuts on the second connecting member 411, and the fourth connecting member 413 is rearward toward the rear in the front-rear direction. Component FR is generated. As a result, the engaging convex portion 73 is inserted into the first lock recess 19 or the second lock recess 20 to engage, or frictionally contacts the inner wall surface of the back wall 13 of the support column 12 to generate a frictional force F4. Let me.

また、ロック状態において、押し下げ力Ｆ０が被昇降体（図示せず）を介して取付ブラケット１００に作用すると、第１実施形態で説明したように、係合凸部７３の斜面と第１ロック凹部１９（第２ロック凹部２０）の穴部の斜面との接触で生じる楔効果で前方分力ＦＦが発生し、ロックが解除される。 Further, when the pushing down force F0 acts on the mounting bracket 100 via the lifting body (not shown) in the locked state, the slope of the engaging convex portion 73 and the first locking concave portion are as described in the first embodiment. The front component force FF is generated by the wedge effect generated by the contact with the slope of the hole portion of 19 (second lock recess 20), and the lock is released.

なお、前記リンク機構は、第２連結部材４１１は前壁部４１６との当接で前後方向後方への移動が規制されているので、リンク機構の変形を許容できるように、第１連結部材４１１と第３連結部材４１２は、前後方向に沿って移動可能に、例えばローラ構造とする。また、第２連結部材４１１は、昇降方向に移動可能に、例えばローラ構造とする。 In the link mechanism, since the second connecting member 411 is restricted from moving backward in the front-rear direction due to contact with the front wall portion 416, the first connecting member 411 can tolerate deformation of the link mechanism. And the third connecting member 412 have a roller structure, for example, so as to be movable along the front-rear direction. Further, the second connecting member 411 has a roller structure, for example, so as to be movable in the elevating direction.

本実施形態によれば、簡単な構成で保持機構兼ロック機構を構成することができる。 According to this embodiment, the holding mechanism and the locking mechanism can be configured with a simple configuration.

なお、上記した各実施形態において、係合凸部７３は、前後方向の後方に向けて移動することで、ロックおよび停止の各動作を行っているが、前後方向の後方への移動に限定されるものではない。例えば、係合凸部７３の移動方向を前後方向の前方、左右方向の左方向または右方向であっても良く、係合凸部７３の移動方向の前方に第１、第２ロック凹部１９，２０と、支柱１２の壁部を設ければ良い。 In each of the above-described embodiments, the engaging convex portion 73 performs each lock and stop operation by moving toward the rear in the front-rear direction, but is limited to the rearward movement in the front-rear direction. It's not something. For example, the moving direction of the engaging convex portion 73 may be forward in the front-rear direction, left or right in the left-right direction, and the first and second lock recesses 19, 20 and the wall portion of the support column 12 may be provided.

本発明は、以上のように構成したので、構造簡単で安価に提供できる液晶モニター等の表示装置の昇降装置、及びこの昇降装置を用いた表示装置を提供できるものである。 Since the present invention is configured as described above, it is possible to provide an elevating device for a display device such as a liquid crystal monitor which has a simple structure and can be provided at low cost, and a display device using the elevating device.
