次に、このような回転表示装置の作用について説明する。
まず、この回転表示装置を第1、第2の各高さ調整支持部材30、31を用いずに組み立てる場合について説明する。このときには、まず、機器搭載部材2に表示装置1を組み付け、この状態で表示装置1の表示回路部1aに接続ケーブル27を接続し、この接続ケーブル27を機器搭載部材2の取付部5から機器搭載部材2の外部に引き出す。
Next, the operation of such a rotary display device will be described.
First, the case where this rotary display device is assembled without using the first and second height adjustment support members 30 and 31 will be described. At this time, first, the display device 1 is assembled to the device mounting member 2, and in this state, the connection cable 27 is connected to the display circuit portion 1a of the display device 1, and the connection cable 27 is connected to the mounting portion 5 of the device mounting member 2 Pull out to the outside of the mounting member 2.
この状態で、機器搭載部材2の取付部5に回転連結部材4を取り付ける。このときには、接続ケーブル27の表示側コネクタ27aを回転連結部材4内に挿入させて回転連結部材4の筒軸部13から引き出す。そして、上下回転機構部7における回転連結部材4の一対の支持突起部12を機器搭載部材2の取付部5内に挿入させて、一対の支持突起部12を取付部5内に設けられた一対の支持アーム部11間に配置する。
In this state, the rotary connection member 4 is attached to the attachment portion 5 of the device mounting member 2. At this time, the display-side connector 27 a of the connection cable 27 is inserted into the rotary connection member 4 and pulled out from the cylindrical shaft portion 13 of the rotary connection member 4. Then, the pair of support protrusions 12 of the rotation connection member 4 in the vertical rotation mechanism 7 are inserted into the attachment portion 5 of the device mounting member 2, and the pair of support protrusions 12 are provided in the attachment portion 5. Between the support arms 11 of the
このときには、上下回転機構部7における一対の支持突起部12に設けられた一対の弾性軸部10が、一対の支持アーム部11の各対向部11aによって互いに接近する方向に押される。このため、上下回転機構部7における一対の弾性軸部10は、その外周に沿って形成されたスリット孔12aによって、互いに接近する方向に弾性変形して一対の支持アーム11の各対向部11a間に配置される。
At this time, the pair of elastic shaft portions 10 provided on the pair of support protrusions 12 in the vertical rotation mechanism 7 are pushed in the direction in which they approach each other by the opposing portions 11 a of the pair of support arms 11. For this reason, the pair of elastic shaft portions 10 in the vertical rotation mechanism portion 7 is elastically deformed in the direction approaching each other by the slit holes 12a formed along the outer periphery thereof, and between the opposing portions 11a of the pair of support arms 11 Will be placed.
この状態で、一対の弾性軸部10が一対の支持突起部12の各軸受部9に対応した際に、一対の弾性軸部10が互いに押し広げられる方向に弾性変形して、一対の弾性軸部10が一対の支持突起部12の各軸受部9内に回転可能に挿入して嵌合する。これにより、回転連結部材4が機器搭載部材2に回転可能に連結され、上下回転機構部7が構成される。この状態では、一対の弾性軸部10を中心に機器搭載部材2が上下方向に回転する。
In this state, when the pair of elastic shaft portions 10 correspond to the bearing portions 9 of the pair of support projections 12, the elastic shaft portions 10 are elastically deformed in the direction in which they are mutually spread, and the pair of elastic shafts The portion 10 is rotatably inserted and fitted in each bearing portion 9 of the pair of support protrusions 12. Thus, the rotary connection member 4 is rotatably connected to the device mounting member 2, and the vertical rotation mechanism unit 7 is configured. In this state, the device mounting member 2 is vertically rotated about the pair of elastic shaft portions 10.
また、このときには、仰角調整機構14における一対の仰角ラック16に一対の仰角弾性突起17が移動可能に係合する。すなわち、一対の仰角ラック16は、上下回転機構部7の回転中心である一対の弾性軸部10を中心とする円弧上に位置する機器搭載部材2の取付部5の内面、つまり一対の弾性軸部10が設けられた回転連結部材4の一対の支持突起部12の各外周に対応する機器搭載部材2の取付部5の内面にそれぞれ一体に形成されている。
At this time, the pair of elevation elastic projections 17 movably engage with the pair of elevation racks 16 in the elevation adjustment mechanism 14. That is, the pair of elevation racks 16 is an inner surface of the mounting portion 5 of the device mounting member 2 positioned on an arc centered on the pair of elastic shaft portions 10 which is the rotation center of the vertical rotation mechanism portion 7, ie, a pair of elastic shafts It is integrally formed on the inner surface of the mounting portion 5 of the device mounting member 2 corresponding to each outer periphery of the pair of support protrusions 12 of the rotational connection member 4 provided with the portion 10.
一方、仰角調整機構14の一対の仰角弾性突起17は、回転連結部材4の一対の支持突起部12の各上部外周に一体に形成されている。このため、一対の弾性軸部10が一対の支持突起部12の各軸受部9に回転可能に嵌合した際には、一対の仰角弾性突起17が一対の仰角ラック16の複数の係止歯16aのいずれかの間に弾力的に係合する。これにより、仰角調整機構14が構成され、回転連結部材4に対する機器搭載部材2の上下方向における回転角度が規制されて、機器搭載部材2の仰角が調整可能な状態になる。
On the other hand, the pair of elevation angle elastic projections 17 of the elevation angle adjustment mechanism 14 are integrally formed on the upper outer periphery of the pair of support projections 12 of the rotary connection member 4. For this reason, when the pair of elastic shaft portions 10 is rotatably fitted to the bearing portions 9 of the pair of support protrusions 12, the pair of elevation angle elastic protrusions 17 are a plurality of locking teeth of the pair of elevation angle racks 16. Elastically engage between any of 16a. Thus, the elevation angle adjustment mechanism 14 is configured, the rotation angle of the device mounting member 2 in the vertical direction with respect to the rotational connection member 4 is restricted, and the elevation angle of the device mounting member 2 can be adjusted.
この後、回転連結部材4を台座3に取り付ける。このときには、予め、接続ケーブル27の表示側コネクタ27aを台座3の台座側コネクタ27bに接続する。そして、水平回転機構部8における台座3に設けられた嵌合筒部6に、回転連結部材4の下部に形成された筒軸部13を差し込んで回転可能に取り付ける。
Thereafter, the rotary connection member 4 is attached to the pedestal 3. At this time, the display connector 27 a of the connection cable 27 is connected to the pedestal connector 27 b of the pedestal 3 in advance. Then, the cylindrical shaft portion 13 formed at the lower part of the rotary connection member 4 is inserted into the fitting cylindrical portion 6 provided on the pedestal 3 in the horizontal rotation mechanism portion 8 and rotatably attached.
このときには、筒軸部13の上部外周に設けられた当接部13aが嵌合筒部6の上端部に回転可能に当接し、台座3に対する回転連結部材4の上下方向の高さ位置が規制される。これにより、水平回転機構部8が構成され、回転連結部材4が台座3に対してその嵌合筒部6の軸回りである水平方向に回転可能な状態で取り付けられる。
At this time, the contact portion 13a provided on the upper outer periphery of the cylindrical shaft portion 13 rotatably contacts the upper end portion of the fitting cylindrical portion 6, and the height position of the rotational connection member 4 with respect to the pedestal 3 is restricted. Be done. Thus, the horizontal rotation mechanism 8 is configured, and the rotation connection member 4 is attached to the pedestal 3 so as to be rotatable in the horizontal direction around the axis of the fitting cylinder 6.
この状態では、回転連結部材4の上部に設けられた上下回転機構部7によって、機器搭載部材2が回転連結部材4に上下方向に回転可能に保持されると共に、回転連結部材4の下部に設けられた水平回転機構部8によって、台座3に回転連結部材4が嵌合筒部6の軸回りである水平方向に回転可能に取り付けられる。これにより、回転連結部材4によって台座3と機器搭載部材2とが連結され、この状態で台座3の上方に機器搭載部材2が保持される。
In this state, the device mounting member 2 is rotatably held by the rotary connection member 4 in the vertical direction by the vertical rotation mechanism 7 provided at the upper portion of the rotary connection member 4 and provided at the lower portion of the rotary connection member 4. The rotary connection member 4 is rotatably attached to the pedestal 3 in the horizontal direction, which is about the axis of the fitting cylinder 6, by the horizontal rotation mechanism 8. As a result, the pedestal 3 and the device mounting member 2 are connected by the rotary connection member 4, and the device mounting member 2 is held above the pedestal 3 in this state.
このように、水平回転機構部8によって回転連結部材4が台座3に対して回転可能に取り付けられる際には、回転角調整機構15における回転ラック18に回転弾性突起19が移動可能に係合する。すなわち、回転ラック18は、台座3の嵌合筒部6の内周面に一体に形成されている。回転弾性突起19は、回転連結部材4の筒軸部13の外周部に一体に形成され、この回転弾性突起19の上部外周から回転弾性突起19の両側に亘ってスリット孔20が設けられている。
As described above, when the rotary connection member 4 is rotatably attached to the pedestal 3 by the horizontal rotation mechanism unit 8, the rotation elastic projection 19 is movably engaged with the rotation rack 18 in the rotation angle adjustment mechanism 15. . That is, the rotating rack 18 is integrally formed on the inner peripheral surface of the fitting cylindrical portion 6 of the pedestal 3. The rotary elastic projection 19 is integrally formed on the outer peripheral portion of the cylindrical shaft portion 13 of the rotary connection member 4, and the slit holes 20 are provided from the upper outer periphery of the rotary elastic projection 19 to both sides of the rotary elastic projection 19. .
このため、回転連結部材4が台座3に対して回転可能に取り付けられた際には、回転弾性突起19が回転ラック18の複数の係止歯18aのいずれかの間に弾力的に係合する。これにより、回転角調整機構15が構成され、台座3に対する回転連結部材4の水平方向における回転角度が規制されて、機器搭載部材2の水平方向における回転角が調整可能な状態になる。
For this reason, when the rotary connection member 4 is rotatably attached to the pedestal 3, the rotary elastic projection 19 elastically engages between any of the plurality of locking teeth 18 a of the rotary rack 18. . Thereby, the rotation angle adjustment mechanism 15 is configured, the rotation angle in the horizontal direction of the rotation connection member 4 with respect to the pedestal 3 is restricted, and the rotation angle in the horizontal direction of the device mounting member 2 can be adjusted.
また、このときには、回転規制部21における筒軸部13の外周に設けられた規制突起22が、その上部外周から規制突起22の両側部に沿って形成されたスリット孔22aによって径方向に弾性変形して、台座3の嵌合筒部6の内周に設けられた規制溝23内に移動可能に挿入する。すなわち、規制溝23は、回転ラック18の下側に位置する嵌合筒部6の内周に320度の範囲で形成されており、この規制溝23の両端部間には、筒軸部13の規制突起22が当接するストッパ部23aが設けられている。
Further, at this time, the restriction protrusion 22 provided on the outer periphery of the cylindrical shaft portion 13 in the rotation restriction portion 21 is elastically deformed in the radial direction by the slit holes 22a formed along the both sides of the restriction protrusion 22 from the upper outer periphery thereof. And movably inserted into the restriction groove 23 provided on the inner periphery of the fitting cylindrical portion 6 of the pedestal 3. That is, the restricting groove 23 is formed in the range of 320 degrees on the inner periphery of the fitting cylindrical portion 6 located below the rotating rack 18, and the cylindrical shaft portion 13 is formed between both ends of the restricting groove 23. The stopper part 23a which the control protrusion 22 of this contact | abuts is provided.
これにより、筒軸部13の規制突起22が台座3の嵌合筒部6の規制溝23内に挿入された状態で、回転連結部材4が回転する際には、規制突起22が規制溝23内を移動する。そして、回転連結部材4が320度回転すると、規制突起22が規制溝23の両端部間に位置するストッパ部23aに当接する。これにより、回転連結部材4が1回転以上回転することがない。
Thus, when the rotary connection member 4 is rotated in a state where the restricting protrusion 22 of the cylindrical shaft portion 13 is inserted into the restricting groove 23 of the fitting cylindrical portion 6 of the pedestal 3, the restricting protrusion 22 is a restricting groove 23. Move inside Then, when the rotary connection member 4 rotates 320 degrees, the restricting projection 22 abuts on the stopper portion 23 a located between both ends of the restricting groove 23. Thereby, the rotational connection member 4 does not rotate more than one rotation.
さらに、水平回転機構部8によって回転連結部材4が台座3に対して回転可能に取り付けられる際には、ロック機構部24における回転連結部材4の筒軸部13の下部に設けられた一対の上側弾性フック部25が、台座3の嵌合筒部6の内周面に設けられた係止溝部26にその円周方向に沿って移動可能に係止される。
Furthermore, when the rotary connection member 4 is rotatably attached to the pedestal 3 by the horizontal rotation mechanism portion 8, a pair of upper sides provided in the lower portion of the cylindrical shaft portion 13 of the rotation connection member 4 in the lock mechanism portion 24 The elastic hook portion 25 is movably engaged with the engagement groove portion 26 provided on the inner peripheral surface of the fitting cylindrical portion 6 of the pedestal 3 along the circumferential direction.
すなわち、一対の上側弾性フック部25は、回転連結部材4の筒軸部13の下部からその径方向に突出して形成され、その両側に一対の上側スリット孔25aが軸方向に沿って設けられている。このため、一対の上側弾性フック部25は、一対の上側スリット孔25aによって筒軸部13の外周面からその径方向に弾性変形する。また、係止溝部26は、台座3の嵌合筒部6の内周面にその円周方向に沿って環状に形成されている。
That is, the pair of upper elastic hook portions 25 are formed so as to protrude in the radial direction from the lower portion of the cylindrical shaft portion 13 of the rotary connection member 4, and a pair of upper slit holes 25a are provided along the axial direction on both sides thereof. There is. For this reason, the pair of upper elastic hook portions 25 are elastically deformed in the radial direction from the outer peripheral surface of the cylindrical shaft portion 13 by the pair of upper slit holes 25a. Further, the locking groove portion 26 is formed annularly along the circumferential direction on the inner peripheral surface of the fitting cylindrical portion 6 of the pedestal 3.
これにより、一対の上側弾性フック部25は、回転連結部材4の筒軸部13が台座3の嵌合筒部6に上方から差し込まれる際に、一対の上側スリット孔25aによって筒軸部13の外周面からその径方向に弾性変形して係止溝部26内に挿入されて係止される。この状態では、回転連結部材4の筒軸部13が台座3の嵌合筒部6内で回転する際に、一対の上側弾性フック部25が係止溝部26内に沿って回転移動しても、回転連結部材4の筒軸部13が台座3の嵌合筒部6内から抜け出すことがない。
Thus, when the cylindrical shaft portion 13 of the rotary connection member 4 is inserted into the fitting cylindrical portion 6 of the pedestal 3 from the upper side, the pair of upper elastic hook portions 25 of the cylindrical shaft portion 13 is formed by the pair of upper slit holes 25a. It is elastically deformed in the radial direction from the outer peripheral surface, and is inserted into the locking groove 26 and locked. In this state, even when the cylindrical shaft portion 13 of the rotary connection member 4 rotates in the fitting cylindrical portion 6 of the pedestal 3, even if the pair of upper elastic hook portions 25 rotationally move along the locking groove portion 26. The cylindrical shaft portion 13 of the rotary connection member 4 does not come out of the fitting cylindrical portion 6 of the pedestal 3.
次に、このように組み立てられた回転表示装置の作用について説明する。
まず、表示装置1を前後方向に傾ける場合には、仰角調整機構14の一対の仰角ラック16に対する一対の仰角弾性突起17の係合力に抗して、機器搭載部材2を上下回転機構部7の回転中心を中心に上下方向に回転させれば良い。
Next, the operation of the thus-assembled rotary display will be described.
First, when the display device 1 is to be tilted in the front-rear direction, the device mounting member 2 of the vertical rotation mechanism 7 is against the engagement force of the pair of elevation angle elastic protrusions 17 with the pair of elevation angle racks 16 of the elevation angle adjustment mechanism 14. It may be rotated in the vertical direction about the rotation center.
例えば、表示装置1をほぼ垂直な状態に起立させる場合には、機器搭載部材2の下部を回転連結部材4に向けて押す。すると、機器搭載部材2が上下回転機構部7の回転中心である回転連結部材4の一対の弾性軸部10を中心に図5において反時計回りに回転して起立する。このときには、仰角調整機構14における回転連結部材4の一対の仰角弾性突起17が機器搭載部材2の一対の仰角ラック16に沿って相対的に移動する。
For example, in the case where the display device 1 is erected in a substantially vertical state, the lower portion of the device mounting member 2 is pushed toward the rotational connection member 4. Then, the device mounting member 2 rotates counterclockwise in FIG. 5 around the pair of elastic shaft portions 10 of the rotation connection member 4 which is the rotation center of the vertical rotation mechanism portion 7 and stands up. At this time, the pair of elevation angle elastic projections 17 of the rotary connection member 4 in the elevation angle adjustment mechanism 14 move relatively along the pair of elevation angle racks 16 of the device mounting member 2.
すなわち、仰角弾性突起17は、図5に示すように、仰角ラック16に沿って相対的に反時計回りに移動しながら仰角ラック16の複数の係止歯16aを順次弾力的に乗り越えて、仰角ラック16の最上部に位置する係止歯16a間に係止される。これにより、回転連結部材4に対する機器搭載部材2の上下方向における回転角度が規制されて、機器搭載部材2がほぼ垂直な状態に保持される。
That is, as shown in FIG. 5, the elevation elastic protrusions 17 resiliently move over the plurality of locking teeth 16 a of the elevation rack 16 while moving relatively counterclockwise along the elevation rack 16, and thus the elevation angle It is locked between the locking teeth 16 a located at the top of the rack 16. Thus, the rotation angle of the device mounting member 2 in the vertical direction with respect to the rotational connection member 4 is restricted, and the device mounting member 2 is held in a substantially vertical state.
また、表示装置1を見易い角度に傾ける場合には、機器搭載部材2の上部を回転連結部材4の上部側に向けて押すと、機器搭載部材2が上下回転機構部7の回転中心である回転連結部材4の一対の弾性軸部10を中心に図5において時計回りに回転して傾く。このときにも、仰角調整機構14における回転連結部材4の一対の仰角弾性突起17が機器搭載部材2の一対の仰角ラック16に沿って相対的に移動する。
In addition, when tilting the display device 1 to an easy-to-view angle, pressing the upper portion of the device mounting member 2 toward the upper side of the rotation connection member 4 causes the device mounting member 2 to rotate about the rotation center 5 rotates clockwise in FIG. 5 around the pair of elastic shaft portions 10 of the connecting member 4 and tilts. Also at this time, the pair of elevation angle elastic projections 17 of the rotary connection member 4 in the elevation angle adjustment mechanism 14 move relatively along the pair of elevation angle racks 16 of the device mounting member 2.
すなわち、仰角弾性突起17は、図5に示すように、仰角ラック16に沿って相対的に時計回りに移動しながら仰角ラック16の複数の係止歯16aを順次弾力的に乗り越えて、仰角ラック16の下部側に位置する係止歯16a間に係止される。これにより、回転連結部材4に対する機器搭載部材2の上下方向における回転角度が規制されて、機器搭載部材2が所定角度に傾いた状態で保持される。
That is, as shown in FIG. 5, the elevation angle elastic projections 17 resiliently sequentially move over the plurality of locking teeth 16 a of the elevation angle rack 16 while moving relatively clockwise along the elevation angle rack 16, and thereby the elevation angle rack It is locked between the locking teeth 16 a located on the lower side of 16. Thereby, the rotation angle in the vertical direction of the device mounting member 2 with respect to the rotation connection member 4 is restricted, and the device mounting member 2 is held in a state of being inclined at a predetermined angle.
一方、表示装置1を水平方向に回転させる場合には、回転角調整機構15の回転ラック18に対する回転弾性突起19の係合力に抗して、機器搭載部材2を水平回転機構部8の回転中心を中心に水平方向に回転させれば良い。例えば、表示装置1を左右のいずれかの方向に回転させる場合には、機器搭載部材2の左右のいずれかの側部を後方に向けて押す。すると、機器搭載部材2が水平回転機構部8の回転中心である回転連結部材4の筒軸部13の軸中心を中心に台座3の上方で回転する。
On the other hand, when the display device 1 is to be rotated in the horizontal direction, the center of rotation of the horizontal rotation mechanism unit 8 against the engagement force of the rotation elastic projection 19 with the rotation rack 18 of the rotation angle adjustment mechanism 15. Should be rotated horizontally around the For example, when rotating the display device 1 in either the left or right direction, either the left or right side portion of the device mounting member 2 is pushed backward. Then, the device mounting member 2 rotates above the pedestal 3 centering on the axial center of the cylindrical shaft portion 13 of the rotation connection member 4 which is the rotation center of the horizontal rotation mechanism 8.
このときには、回転調整機構15における回転連結部材4の筒軸部13の回転弾性突起19が台座3の嵌合筒部6の回転ラック18に沿って移動する。すなわち、回転弾性突起19が回転ラック18に沿って移動する際には、回転弾性突起19が回転ラック18の複数の係止歯18aを順次弾力的に乗り越えて複数の係止歯18aのいずれかの間に弾力的に係合する。これにより、台座3に対する機器搭載部材2の水平方向における回転角度が規制され、機器搭載部材2の水平方向の回転角が調整される。
At this time, the rotation elastic projection 19 of the cylindrical shaft portion 13 of the rotation connection member 4 in the rotation adjustment mechanism 15 moves along the rotation rack 18 of the fitting cylindrical portion 6 of the pedestal 3. That is, when the rotation elastic projection 19 moves along the rotation rack 18, the rotation elastic projection 19 resiliently climbs over the plurality of locking teeth 18a of the rotation rack 18 in order and any of the plurality of locking teeth 18a. Resiliently engage between Thereby, the rotation angle in the horizontal direction of the device mounting member 2 with respect to the pedestal 3 is restricted, and the rotation angle in the horizontal direction of the device mounting member 2 is adjusted.
この場合、機器搭載部材2が水平回転機構部8の回転中心を中心に回転する際には、回転角調整機構15の回転規制部21によって機器搭載部材2の回転範囲が規制される。すなわち、回転規制部21は、筒軸部13の規制突起22が台座3の嵌合筒部6の規制溝23内に挿入された状態で、回転連結部材4が回転する。
In this case, when the device mounting member 2 rotates around the rotation center of the horizontal rotation mechanism unit 8, the rotation restricting portion 21 of the rotation angle adjusting mechanism 15 restricts the rotation range of the device mounting member 2. That is, in the rotation restricting portion 21, the rotation connection member 4 rotates in a state where the restricting protrusion 22 of the cylindrical shaft portion 13 is inserted into the restricting groove 23 of the fitting cylindrical portion 6 of the pedestal 3.
このときには、規制突起22が規制溝23内を移動し、回転連結部材4が320度回転すると、規制突起22が規制溝23の両端部間に位置するストッパ部23aに当接する。これにより、回転連結部材4が1回転以上回転することがない。このため、表示装置1の表示回路部1bと台座3の台座回路部3aとを接続する接続ケーブル27が1回転以上捩れることがない。
At this time, when the restricting protrusion 22 moves in the restricting groove 23 and the rotational connection member 4 rotates 320 degrees, the restricting protrusion 22 abuts on the stopper portion 23 a located between both ends of the restricting groove 23. Thereby, the rotational connection member 4 does not rotate more than one rotation. Therefore, the connection cable 27 connecting the display circuit portion 1b of the display device 1 and the pedestal circuit portion 3a of the pedestal 3 is not twisted more than one turn.
ところで、この回転表示装置をレジスタが配置された清算所で使用する際に、例えば表示装置1をレジスタの使用者に向けて使用する場合には、台座3を動かす必要がなく、機器搭載部材2を水平回転機構部8によって水平方向に回転させるだけで、表示装置1を使用者に向けることができる。この場合、表示装置1の高さが低過ぎて表示装置1が見にくいときには、機器搭載部材2を上下回転機構部7によって上下方向に回転させて、機器搭載部材2を上向きに傾けることにより、見易くすることができる。
By the way, when this rotary display device is used at a clearinghouse where the register is arranged, for example, when the display device 1 is used for the user of the register, there is no need to move the pedestal 3. The display device 1 can be directed to the user simply by rotating the horizontal rotation mechanism 8 in the horizontal direction. In this case, when the height of the display device 1 is too low and the display device 1 is difficult to see, the device mounting member 2 is rotated in the vertical direction by the vertical rotation mechanism 7 to tilt the device mounting member 2 upward. can do.
また、表示装置1をお客に向けて使用する場合にも、台座3を動かす必要がなく、機器搭載部材2を水平回転機構部8によって水平方向に回転させるだけで、表示装置1をお客に向けることができる。この場合、表示装置1の高さが低過ぎてお客が表示装置1を見にくいときには、機器搭載部材2を上下回転機構部7によって上下方向に回転させて、機器搭載部材2を上向きに傾けることにより、見易くすることができる。
In addition, even when the display device 1 is used for a customer, there is no need to move the base 3, and the display device 1 is directed to the customer only by rotating the device mounting member 2 horizontally by the horizontal rotation mechanism 8. be able to. In this case, when the height of the display device 1 is too low and it is difficult for the customer to see the display device 1, the device mounting member 2 is vertically rotated by the vertical rotation mechanism 7 to tilt the device mounting member 2 upward. It can be easy to see.
次に、この回転表示装置において、表示装置1の高さを調整する場合について説明する。
この場合には、台座3から回転連結部材4を取り外して、第1、第2の各高さ調整支持部材30、31のうち、例えば表示装置1の高さに合う第1の高さ調整支持部材30を台座3に取り付ける。このときには、まず、台座3から回転連結部材4を取り外した際に、接続ケーブル27の表示側コネクタ27aを台座3の台座側コネクタ27bから取り外す。
Next, the case where the height of the display device 1 is adjusted in this rotary display device will be described.
In this case, the rotary connection member 4 is removed from the pedestal 3 and, for example, a first height adjustment support that fits the height of the display device 1 among the first and second height adjustment support members 30 and 31. The member 30 is attached to the pedestal 3. At this time, first, when the rotary connection member 4 is removed from the pedestal 3, the display-side connector 27 a of the connection cable 27 is removed from the pedestal-side connector 27 b of the pedestal 3.
そして、第1の高さ調整支持部材30の上下方向の長さとほぼ同じ長さの延長接続ケーブル44の下側コネクタ44aを台座3の台座側コネクタ27bに接続し、この延長接続ケーブル44を第1の高さ調整支持部材30内に挿入させて、延長接続ケーブル44の上側コネクタ44bを第1の高さ調整支持部材30の上端部から引き出す。この状態で、第1の高さ調整支持部材30を台座3に取り付ける。
Then, the lower connector 44a of the extension connection cable 44 having substantially the same length as the length in the vertical direction of the first height adjustment support member 30 is connected to the pedestal side connector 27b of the pedestal 3, and the extension connection cable 44 is The upper connector 44 b of the extension connection cable 44 is pulled out from the upper end of the first height adjustment support member 30 by being inserted into the height adjustment support member 30 of FIG. In this state, the first height adjustment support member 30 is attached to the pedestal 3.
このときには、第1の高さ調整支持部材30における下側取付機構部32の下側筒軸部34を台座3の嵌合筒部6に差し込んで嵌め込み、下側取付機構部32の下側ロック機構部35によって第1の高さ調整支持部材30の下側筒軸部34を台座3の嵌合筒部6にロックすると共に、回転止め部45によって台座3の嵌合筒部6に対する下側取付機構部32の下側筒軸部34の回転を阻止する。
At this time, the lower cylindrical shaft portion 34 of the lower mounting mechanism portion 32 in the first height adjustment support member 30 is inserted and fitted into the fitting cylindrical portion 6 of the pedestal 3, and the lower lock of the lower mounting mechanism portion 32 The lower cylindrical shaft portion 34 of the first height adjustment support member 30 is locked to the fitting cylindrical portion 6 of the base 3 by the mechanism portion 35, and the lower side of the mounting cylindrical portion 6 of the pedestal 3 by the rotation stopping portion 45 The rotation of the lower cylindrical shaft portion 34 of the mounting mechanism portion 32 is blocked.
すなわち、下側筒軸部34が台座3の嵌合筒部6に差し込まれると、下側ロック機構部35の下側弾性フック部36が、台座3の嵌合筒部6に設けられた下側係止溝部である係止溝部26内に弾力的に挿入されて係止される。これにより、第1の高さ調整支持部材30が台座3の嵌合筒部6から不用意に抜け出すことがなく、台座3の嵌合筒部6に起立した状態で取り付けられる。
That is, when the lower cylindrical shaft portion 34 is inserted into the fitting cylindrical portion 6 of the pedestal 3, the lower elastic hook portion 36 of the lower lock mechanism 35 is provided on the mating cylindrical portion 6 of the pedestal 3. It is elastically inserted and locked in the locking groove 26 which is a side locking groove. As a result, the first height adjustment support member 30 is attached to the fitting cylindrical portion 6 of the pedestal 3 in an upright state without being inadvertently pulled out of the fitting cylindrical portion 6 of the pedestal 3.
また、このときには、台座3の嵌合筒部6の内周面に設けられた回転ラック18の複数の係止歯18aのいずれかの間に、下側取付機構部32の下側筒軸部34の外周面に設けられた固定突起46が噛み合って係止される。これにより、固定突起46が回転ラック18の複数の係止歯18aを乗り越えることがなく、回転ラック18に対して固定されるため、台座3の嵌合筒部6に対して第1の高さ調整支持部材30の下側筒軸部34がその軸方向に回転することがない。
At this time, the lower cylindrical shaft portion of the lower attachment mechanism portion 32 is provided between any one of the plurality of locking teeth 18 a of the rotating rack 18 provided on the inner peripheral surface of the fitting cylindrical portion 6 of the pedestal 3. The fixing projections 46 provided on the outer peripheral surface of the gear 34 are engaged and locked. As a result, the fixing projections 46 do not get over the plurality of locking teeth 18 a of the rotating rack 18 and are fixed to the rotating rack 18, so that the first height relative to the fitting cylindrical portion 6 of the pedestal 3 The lower cylindrical shaft portion 34 of the adjustment support member 30 does not rotate in the axial direction.
この状態で、第1の高さ調整支持部材30に回転連結部材4を取り付ける。このときには、まず、表示装置1の表示回路部1bに接続された接続ケーブル27の表示側コネクタ27aを第1の高さ調整支持部材30の上端部側に位置する延長接続ケーブル44の上側コネクタ44bに接続する。この状態で、第1の高さ調整支持部材30における上側取付機構部33の上側嵌合筒部37に回転連結部材4の上側筒軸部である筒軸部13を差し込んで回転可能に取り付ける。
In this state, the rotational connection member 4 is attached to the first height adjustment support member 30. At this time, first, the upper connector 44 b of the extension connection cable 44 in which the display side connector 27 a of the connection cable 27 connected to the display circuit unit 1 b of the display device 1 is located on the upper end side of the first height adjustment support member 30. Connect to In this state, the cylindrical shaft portion 13 which is the upper cylindrical shaft portion of the rotary connection member 4 is inserted into the upper fitting cylindrical portion 37 of the upper mounting mechanism portion 33 of the first height adjustment support member 30 and rotatably attached.
このときには、上側取付機構部33の上側ロック機構部38によって回転連結部材4の筒軸部13が第1の高さ調整支持部材30の上側嵌合筒部37にロックされる。すなわち、第1の高さ調整支持部材30の上側嵌合筒部37に回転連結部材4の筒軸部13が差し込まれる際には、回転連結部材4の筒軸部13に設けられた上側弾性フック部25が、上側嵌合筒部37の上側係止溝部39内に弾力的に挿入されて係止される。これにより、回転連結部材4の筒軸部13が上側嵌合筒部37内から不用意に抜け出すことがない。
At this time, the cylindrical shaft portion 13 of the rotational connection member 4 is locked to the upper fitting cylindrical portion 37 of the first height adjustment support member 30 by the upper locking mechanism portion 38 of the upper mounting mechanism portion 33. That is, when the cylindrical shaft portion 13 of the rotational connection member 4 is inserted into the upper fitting cylindrical portion 37 of the first height adjustment support member 30, the upper elastic provided on the cylindrical shaft portion 13 of the rotational connection member 4 The hook portion 25 is resiliently inserted and locked in the upper locking groove 39 of the upper fitting cylinder 37. As a result, the cylindrical shaft portion 13 of the rotary connection member 4 does not inadvertently come out of the upper fitting cylindrical portion 37.
また、このように第1の高さ調整支持部材30に回転連結部材4が取り付けられた際には、回転角調整機構40における第1の高さ調整支持部材30の上側嵌合筒部37の内周面に設けられた回転ラック42に、回転連結部材4の筒軸部13の外周面に設けられた回転弾性突起19が、回転ラック42に沿って移動可能な状態で係止される。
Further, when the rotary connection member 4 is attached to the first height adjustment support member 30 in this manner, the upper fitting cylindrical portion 37 of the first height adjustment support member 30 in the rotation angle adjustment mechanism 40 The rotation elastic projection 19 provided on the outer peripheral surface of the cylindrical shaft portion 13 of the rotation connection member 4 is engaged with the rotation rack 42 provided on the inner peripheral surface so as to be movable along the rotation rack 42.
すなわち、回転角調整機構40は、下側取付機構部32の回転止め部45によって台座3の嵌合筒部6に対して下側筒軸部34が回転することがないため、回転ラック42の複数の係止歯42aを順次弾力的に乗り越えて複数の係止歯42aのいずれかの間に弾力的に係合する。これにより、台座3に対する機器搭載部材2の水平方向における回転角度が規制され、機器搭載部材2の水平方向の回転角が調整される。
That is, in the rotation angle adjustment mechanism 40, the lower cylindrical shaft portion 34 does not rotate with respect to the fitting cylindrical portion 6 of the pedestal 3 by the rotation stopping portion 45 of the lower mounting mechanism portion 32. The plurality of locking teeth 42a are sequentially resiliently overcome and resiliently engaged between any of the plurality of locking teeth 42a. Thereby, the rotation angle in the horizontal direction of the device mounting member 2 with respect to the pedestal 3 is restricted, and the rotation angle in the horizontal direction of the device mounting member 2 is adjusted.
また、このときには、上側取付機構部33の回転規制部41によって、第1の高さ調整支持部材30に対する回転連結部材4の回転範囲が規制される。すなわち、回転規制部41は、回転連結部材4の筒軸部13の外周に設けられた規制突起22が、第1の高さ調整支持部材30の上側嵌合筒部37の内周に設けられた規制溝43内に挿入された状態で、回転連結部材4が回転する。
Further, at this time, the rotation range of the rotation connection member 4 with respect to the first height adjustment support member 30 is restricted by the rotation restriction part 41 of the upper attachment mechanism part 33. That is, in the rotation restricting portion 41, the restricting protrusion 22 provided on the outer periphery of the cylindrical shaft portion 13 of the rotational connection member 4 is provided on the inner periphery of the upper fitting cylindrical portion 37 of the first height adjustment support member 30. In the state of being inserted into the restriction groove 43, the rotary connection member 4 is rotated.
このときには、規制突起22が規制溝43内を移動し、回転連結部材4が320度回転すると、規制突起22が規制溝43の両端部間に位置するストッパ部43aに当接する。これにより、回転連結部材4が1回転以上回転することがない。このため、第1の高さ調整支持部材30内に配置された延長接続ケーブル44およびこれに接続された接続ケーブル27が1回転以上捩れることがない。
At this time, when the restricting protrusion 22 moves in the restricting groove 43 and the rotational connection member 4 rotates 320 degrees, the restricting protrusion 22 abuts on the stopper portion 43 a located between both ends of the restricting groove 43. Thereby, the rotational connection member 4 does not rotate more than one rotation. For this reason, the extension connection cable 44 disposed in the first height adjustment support member 30 and the connection cable 27 connected thereto are not twisted more than one rotation.
これにより、第1の高さ調整支持部材30を台座3に取り付けて表示装置1の高さを調整した場合にも、台座3を動かす必要がなく、機器搭載部材2を上側取付機構部33によって水平方向に回転させるだけで、表示装置1を水平方向に回転させて見易い向きに変えることができる。この場合にも、機器搭載部材2を上下回転機構部7によって上下方向に回転させて、機器搭載部材2の向きを見易い向きに傾けることができる。
Thus, even when the first height adjustment support member 30 is attached to the pedestal 3 to adjust the height of the display device 1, there is no need to move the pedestal 3, and the device mounting member 2 can be moved by the upper attachment mechanism portion 33. Only by rotating it in the horizontal direction, the display device 1 can be rotated in the horizontal direction to be changed into an easy-to-see direction. Also in this case, the device mounting member 2 can be rotated in the vertical direction by the vertical rotation mechanism unit 7 so that the direction of the device mounting member 2 can be inclined in an easy-to-see direction.
ところで、この回転表示装置において表示装置1の高さを更に高く調整する場合には、第1の高さ調整支持部材30を取り外して第2の高さ調整支持部材31に代えれば良い。すなわち、第1の高さ調整支持部材30を取り外す際には、第1の高さ調整支持部材30における上側取付機構部33の上側嵌合筒部37から回転連結部材4の上側筒軸部である筒軸部13を取り外す。
By the way, when adjusting the height of the display device 1 to a higher level in this rotary display device, the first height adjustment support member 30 may be removed and replaced with the second height adjustment support member 31. That is, when the first height adjustment support member 30 is removed, the upper fitting cylindrical portion 37 of the upper attachment mechanism portion 33 in the first height adjustment support member 30 to the upper cylindrical shaft portion of the rotational connection member 4 Remove a certain cylindrical shaft portion 13.
このときには、台座3に着脱可能に取り付けられる下側取付機構部32の着脱力が、回転連結部材4に着脱可能に取り付けられる上側取付機構部33の着脱力よりも大きい。このため、上側取付機構部33における第1の高さ調整支持部材30の上側嵌合筒部37から回転連結部材4の上側筒軸部である筒軸部13を取り外す際には、下側取付機構部32の下側筒軸部34が台座3の嵌合筒部6から抜け出すことがなく、回転連結部材4の筒軸部13を第1の高さ調整支持部材30の上側嵌合筒部37から取り外すことができる。
At this time, the attachment / detachment force of the lower attachment mechanism portion 32 detachably attached to the pedestal 3 is larger than the attachment / detachment force of the upper attachment mechanism portion 33 detachably attached to the rotary connection member 4. Therefore, when removing the cylindrical shaft portion 13 which is the upper cylindrical shaft portion of the rotational connection member 4 from the upper fitting cylindrical portion 37 of the first height adjustment support member 30 in the upper mounting mechanism portion 33, the lower mounting The lower cylindrical shaft portion 34 of the mechanism portion 32 does not come out of the fitting cylindrical portion 6 of the pedestal 3, and the cylindrical shaft portion 13 of the rotary connection member 4 is the upper fitting cylindrical portion of the first height adjustment support member 30. It can be removed from 37.
すなわち、下側取付機構部32の下側筒軸部34に設けられた下側弾性フック部36は、その上側にスリット孔が設けられておらず、回転連結部材4の筒軸部13に設けられた上側弾性フック部25は、そ上側に上側スリット孔25aが軸方向に沿って形成されている。このため、下側弾性フック部36は、その弾性係合力が上側弾性フック部25の弾性係合力よりも大きく形成されている。
That is, the lower elastic hook portion 36 provided on the lower cylindrical shaft portion 34 of the lower mounting mechanism portion 32 is not provided with a slit hole on the upper side thereof, and provided on the cylindrical shaft portion 13 of the rotational connection member 4 An upper slit hole 25a is formed on the upper side of the upper elastic hook portion 25 along the axial direction. For this reason, the elastic engagement force of the lower elastic hook portion 36 is formed larger than the elastic engagement force of the upper elastic hook portion 25.
これにより、機器搭載部材2を第1の高さ調整支持部材30から取り外際に、第1の高さ調整支持部材30の下側筒軸部34が台座3の嵌合筒部6から抜け出すことがなく、回転連結部材4の筒軸部13を第1の高さ調整支持部材30の上側嵌合筒部37から取り外すことができる。
As a result, when the device mounting member 2 is removed from the first height adjustment support member 30, the lower cylindrical shaft portion 34 of the first height adjustment support member 30 is disengaged from the fitting cylindrical portion 6 of the pedestal 3 Without this, the cylindrical shaft portion 13 of the rotational connection member 4 can be removed from the upper fitting cylindrical portion 37 of the first height adjustment support member 30.
このように、機器搭載部材2に取り付けられた回転連結部材4を第1の高さ調整支持部材30から取り外す際に、必ず、回転連結部材4の筒軸部13を第1の高さ調整支持部材30の上側嵌合筒部37から取り外すことができるので、機器搭載部材2を第1の高さ調整支持部材30から安全に取り外すことができ、これにより機器搭載部材2を落として表示装置1を破損する恐れがないので、使い勝手が良い。
As described above, when the rotary connection member 4 attached to the device mounting member 2 is removed from the first height adjustment support member 30, the cylindrical shaft portion 13 of the rotary connection member 4 is always supported by the first height adjustment The device mounting member 2 can be safely removed from the first height adjustment support member 30 because the device mounting member 2 can be removed from the upper fitting cylindrical portion 37 of the member 30, and the device mounting member 2 is thereby dropped. It is easy to use because there is no risk of damaging it.
このように、第1の高さ調整支持部材30を取り外した後は、第2の高さ調整支持部材31を第1の高さ調整支持部材30と同様に台座3に取り付けることができ、この第2の高さ調整支持部材31の上部に回転連結部材4を取り付けることができる。これにより、表示装置1の高さを更に高くすることができる。このときにも、延長接続ケーブル44を第2の調整支持部材31の上下方向の長さと同じ長さの延長接続ケーブル(図示せず)に交換すればよい。
Thus, after removing the first height adjustment support member 30, the second height adjustment support member 31 can be attached to the pedestal 3 in the same manner as the first height adjustment support member 30, The rotary connection member 4 can be attached to the top of the second height adjustment support member 31. Thereby, the height of the display device 1 can be further increased. Also in this case, the extension connection cable 44 may be replaced with an extension connection cable (not shown) having the same length as the length of the second adjustment support member 31 in the vertical direction.
このように、この回転表示装置によれば、機器である表示装置1を搭載する機器搭載部材2と、この機器搭載部材2の下側に位置する台座3と、機器搭載部材2を上下方向に回転可能に保持する上下回転機構部7、および台座3に対して水平方向に回転可能に取り付けられる水平回転機構部8を有し、機器搭載部材2を台座3に連結する回転連結部材4と、を備えていることにより、部品点数を抑制した簡単な構造で、容易に組立作業ができ、生産性の向上を図ることができる。
As described above, according to this rotary display device, the device mounting member 2 for mounting the display device 1 as a device, the pedestal 3 positioned below the device mounting member 2, and the device mounting member 2 in the vertical direction A rotation connecting member 4 having an up-and-down rotation mechanism 7 rotatably held and a horizontal rotation mechanism 8 rotatably attached in the horizontal direction with respect to the pedestal 3 and coupling the device mounting member 2 to the pedestal 3; As a result, the assembly work can be easily performed with a simple structure in which the number of parts is suppressed, and productivity can be improved.
すなわち、この回転表示装置では、上下回転機構部7によって回転連結部材4を機器搭載部材2に上下方向に回転可能な状態で連結することができると共に、水平回転機構部8によって回転連結部材4を台座3に対して水平方向に回転可能な状態で連結することができる。このため、回転連結部材4のみによって機器搭載部材2を台座3に簡単に取り付けることができるので、構造が簡単で、別部品を全く必要としないため、部品点数を抑えることができると共に、組立作業が容易にでき、生産性の向上を図ることができる。
That is, in this rotary display device, the rotary connection member 4 can be rotatably connected to the device mounting member 2 in the vertical direction by the vertical rotation mechanism unit 7, and the rotary connection member 4 is connected by the horizontal rotation mechanism unit 8. It can be connected to the pedestal 3 so as to be rotatable in the horizontal direction. Therefore, since the device mounting member 2 can be easily attached to the base 3 only by the rotary connection member 4, the structure is simple and no separate parts are required, so that the number of parts can be reduced and the assembly operation is performed. It is easy to improve productivity.
この場合、上下回転機構部7は、機器搭載部材2に設けられた軸受部9と、回転連結部材4に設けられて軸受部9にその軸方向に弾性変形して嵌合する弾性軸部10と、を備えていることにより、回転連結部材4を機器搭載部材2に連結する際に、回転連結部材4の弾性軸部10を弾性変形させることができるので、この弾性軸部10の弾性変形によって弾性軸部10を機器搭載部材2の軸受部9に簡単にかつ容易に嵌合させることができ、これにより弾性軸部10を中心に機器搭載部材2を回転連結部材4に対して上下方向に回転可能な状態で確実にかつ良好に取り付けることができる。
In this case, the vertical rotation mechanism unit 7 includes a bearing unit 9 provided on the device mounting member 2 and an elastic shaft unit 10 provided on the rotary connection member 4 and elastically deformed in the axial direction of the bearing unit 9. The elastic shaft portion 10 of the rotational connection member 4 can be elastically deformed when the rotational connection member 4 is connected to the device mounting member 2 by including the and the elastic deformation of the elastic shaft portion 10. Thus, the elastic shaft portion 10 can be easily and easily fitted to the bearing portion 9 of the device mounting member 2, whereby the device mounting member 2 can be vertically moved with respect to the rotational connection member 4 centering on the elastic shaft portion 10 Can be mounted securely and well in a rotatable state.
すなわち、上下回転機構部7の軸受部9は、機器搭載部材2の取付部5内に互いに接近または離間する方向に弾性変形するように形成されたU字形状の一対の支持アーム11の互いに対向する対向部11aにそれぞれ同一軸上に対応して一体に形成されており、上下回転機構部7の弾性軸部10は、回転連結部材4の上部両側にその上方に向けて突出した状態で一体に形成された一対の支持突起部12に一体に形成され、この弾性軸部10の上部外周から下側に向けて逆U字形状にスリット孔12aが設けられていることにより、弾性軸部10を軸受部9に簡単にかつ容易に嵌合させることができる。
That is, the bearing portions 9 of the vertical rotation mechanism portion 7 are opposed to each other of the pair of U-shaped support arms 11 formed to be elastically deformed in the mounting portion 5 of the device mounting member 2 in a direction approaching or separating from each other. The elastic shaft portions 10 of the vertical rotation mechanism portion 7 are integrally formed in such a manner that they project upward on both upper sides of the rotary connection member 4 in a corresponding manner on the same axis. The elastic shaft portion 10 is formed integrally with the pair of support projection portions 12 formed on the upper surface of the elastic shaft portion 10 from the upper outer periphery of the elastic shaft portion 10 in a reverse U-shape. Can be fitted into the bearing 9 simply and easily.
この場合、この上下回転機構部7では、回転連結部材4の上部を機器搭載部材2の取付部5内に下側から挿入させて、一対の支持突起部12を取付部5内の一対の支持アーム11間に配置させるだけで、一対の支持突起部12の各スリット孔12aによって一対の弾性軸部10を互いに接近する方向に弾性させることができるので、別部品を必要とせずに、簡単に一対の弾性軸部10を一対の支持アーム11の各対向部11a間に配置することができる。
In this case, in the vertical rotation mechanism unit 7, the upper portion of the rotary connection member 4 is inserted from the lower side into the mounting portion 5 of the device mounting member 2 to support the pair of support protrusions 12 in the mounting portion 5. Since the pair of elastic shaft portions 10 can be made to be elastic in directions approaching each other by the respective slit holes 12a of the pair of support projections 12 only by being disposed between the arms 11, it is possible to simply do not need separate parts. The pair of elastic shaft portions 10 can be disposed between the facing portions 11 a of the pair of support arms 11.
また、この上下回転機構部7では、一対の弾性軸部10を一対の支持アーム11の各対向部11a間に配置させた状態で、一対の弾性軸部10を一対の支持突起部12の各軸受部9に対応させると、一対の弾性軸部10を互いに押し広げられる方向に弾性変形させることができるので、一対の弾性軸部10を一対の支持突起部12の各軸受部9に簡単にかつ確実に嵌合させることができる。これにより、回転連結部材4を機器搭載部材2に回転可能に連結させることができると共に、各弾性軸部10を中心に機器搭載部材2を回転連結部材4に対して上下方向に良好に回転させることができる。
Further, in the vertical rotation mechanism unit 7, the pair of elastic shaft portions 10 is arranged in each of the pair of support projection portions 12 in a state where the pair of elastic shaft portions 10 is arranged between the opposing portions 11 a of the pair of support arms 11. Since the pair of elastic shaft portions 10 can be elastically deformed in the direction in which the pair of elastic shaft portions 10 can be spread apart if they correspond to the bearing portions 9, the pair of elastic shaft portions 10 can be easily attached to the bearing portions 9 of the pair of support protrusions 12. And it can be made to fit certainly. Thus, the rotary connection member 4 can be rotatably connected to the device mounting member 2, and the device mounting member 2 can be favorably rotated in the vertical direction with respect to the rotary connection member 4 around each elastic shaft portion 10. be able to.
また、水平回転機構部8は、台座3に設けられた嵌合筒部6と、回転連結部材4に設けられて嵌合筒部6に回転可能に嵌合する筒軸部13と、を備えていることにより、回転連結部材4を台座3に連結する際に、回転連結部材4の筒軸部13を台座3の嵌合筒部6に差し込むだけで、回転連結部材4の筒軸部13を台座3の嵌合筒部6に簡単にかつ容易に嵌合させることができ、これにより台座3の嵌合筒部6の軸中心を中心にして回転連結部材4を台座3に対して水平方向に回転可能な状態で確実にかつ良好に取り付けることができる。
The horizontal rotation mechanism 8 also includes a fitting cylinder 6 provided on the pedestal 3 and a cylinder shaft 13 provided on the rotary connection member 4 and rotatably fitted on the fitting cylinder 6. Thus, when connecting the rotary connection member 4 to the pedestal 3, the cylindrical shaft portion 13 of the rotary connection member 4 is simply inserted into the fitting cylindrical portion 6 of the pedestal 3. Can be easily and easily fitted to the fitting cylindrical portion 6 of the pedestal 3, whereby the rotational connection member 4 is horizontal with respect to the pedestal 3 about the axial center of the fitting cylindrical portion 6 of the pedestal 3 It can be mounted reliably and well in a rotatable manner in the direction.
この場合、この回転表示装置は、台座3に対して回転連結部材4を回転可能な状態で軸方向に対してロックするロック機構部24を備えていることにより、回転連結部材4の筒軸部13を台座3の嵌合筒部6に差し込んだ際に、ロック機構部24によって回転連結部材4の筒軸部13を台座3の嵌合筒部6に回転可能な状態で軸方向に対してロックすることができ、これにより回転連結部材4の筒軸部13が台座3の嵌合筒部6から不用意に抜け出すのを防ぐことができる。
In this case, the rotary display device includes the lock mechanism portion 24 that locks the rotary connection member 4 in the axial direction in a rotatable state with respect to the pedestal 3 so that the cylindrical shaft portion of the rotary connection member 4 When 13 is inserted into the fitting cylindrical portion 6 of the pedestal 3, the lock mechanism portion 24 can rotate the cylindrical shaft portion 13 of the rotary connection member 4 to the fitting cylindrical portion 6 of the pedestal 3 with respect to the axial direction It can be locked, which can prevent the cylindrical shaft portion 13 of the rotary connection member 4 from inadvertently coming out of the fitting cylindrical portion 6 of the pedestal 3.
すなわち、このロック機構部24は、回転連結部材4の下部外周に設けられた上側弾性フック部25と、台座3の嵌合筒部6に設けられて上側弾性フック部25を回転移動可能に係止する係止溝部26と、を備えていることにより、回転連結部材4の筒軸部13を台座3の嵌合筒部6に差し込む際に、上側弾性フック部25が弾性変形して係止溝部26内に挿入するので、上側弾性フック部25を係止溝部26に簡単にかつ容易に係止させることができる。
That is, the lock mechanism portion 24 is provided on the upper elastic hook portion 25 provided on the lower outer periphery of the rotary connection member 4 and the fitting cylindrical portion 6 of the pedestal 3 so that the upper elastic hook portion 25 can rotate and move. The upper elastic hook portion 25 is elastically deformed and locked when inserting the cylindrical shaft portion 13 of the rotary connection member 4 into the fitting cylindrical portion 6 of the base 3 by including the locking groove portion 26 to be stopped. Since the upper elastic hook portion 25 is inserted into the groove portion 26, the upper elastic hook portion 25 can be easily and easily engaged with the engagement groove portion 26.
また、この回転表示装置では、回転連結部材4の回転範囲を規制する回転規制部21を備えていることにより、回転連結部材4の回転範囲を所定の角度範囲に位置規制することができる。すなわち、この回転規制部21は、筒軸部13の規制突起22が台座3の嵌合筒部6の規制溝23内に挿入された状態で、回転連結部材4が回転する際に、規制突起22を規制溝23の両端部間に位置するストッパ部23aに当接させることにより、回転連結部材4の回転範囲を所定の角度範囲に位置規制することができる。
Further, in the rotary display device, the rotation restricting portion 21 restricting the rotation range of the rotation connection member 4 can positionally restrict the rotation range of the rotation connection member 4 to a predetermined angle range. That is, when the rotation connection member 4 is rotated, the rotation restricting portion 21 rotates in a state where the restricting projection 22 of the cylindrical shaft portion 13 is inserted into the restricting groove 23 of the fitting cylindrical portion 6 of the pedestal 3. By bringing 22 into contact with the stopper portion 23 a located between both ends of the regulating groove 23, it is possible to positionally restrict the rotational range of the rotary connecting member 4 to a predetermined angular range.
この場合、回転規制部21は、回転連結部材4の回転範囲を180度〜330度の角度範囲で、好ましくは320度の角度範囲で位置規制することにより、機器搭載部材2を水平方向に良好に回転させることができると共に、回転連結部材4が1回転以上回転するのを防ぐことができ、これにより表示装置1の表示回路部1bと台座3の台座回路部3aとを接続する接続ケーブル27が1回転以上捩れないようにすることができる。
In this case, the rotation restricting portion 21 positions the rotation range of the rotation connecting member 4 in the angle range of 180 degrees to 330 degrees, preferably in the angle range of 320 degrees, so that the device mounting member 2 is good in the horizontal direction. The connection cable 27 for connecting the display circuit portion 1 b of the display device 1 and the pedestal circuit portion 3 a of the pedestal 3 can be prevented, and the rotational connection member 4 can be prevented from rotating more than one rotation. Can be twisted more than one turn.
このように、この回転表示装置では、回転連結部材4の上部に設けられた上下回転機構部7によって機器搭載部材2を上下方向に回転可能に保持することができると共に、回転連結部材4の下部に設けられた水平回転機構部8によって回転連結部材4の筒軸部13を台座3の嵌合筒部6にその軸回りである水平方向に回転可能に取り付けることができ、これにより別部品を全く必要とせずに、必要最小限の部品点数で、台座3と機器搭載部材2とを確実にかつ良好に連結することができ、この状態で台座3の上方に機器搭載部材2を良好に保持することができる。
As described above, in this rotary display device, the device mounting member 2 can be rotatably held in the vertical direction by the vertical rotation mechanism 7 provided on the upper portion of the rotary connection member 4 and the lower portion of the rotary connection member 4 Can be attached to the fitting cylindrical portion 6 of the pedestal 3 so as to be rotatable in the horizontal direction, which is about its axis, by means of the horizontal rotation mechanism 8 provided in the The pedestal 3 and the device mounting member 2 can be reliably and favorably connected with the minimum number of parts without any need, and the device mounting member 2 is well held above the pedestal 3 in this state can do.

The rotary display device further includes an elevation adjustment mechanism 14 for adjusting the vertical rotation angle of the device mounting member 2 and a rotation angle adjustment mechanism 15 for adjusting the horizontal rotation angle of the device mounting member 2. Thus, the vertical angle of rotation of the device mounting member 2 can be adjusted by the elevation angle adjusting mechanism 14 to favorably adjust the inclination of the display device 1 in the vertical direction, and the device mounting by the rotational angle adjusting mechanism 15 By adjusting the rotation angle of the member 2 in the horizontal direction, the direction in the left and right direction of the display device 1 can be favorably adjusted.
この場合、仰角調整機構14は、機器搭載部材2の取付部5内にその回転中心を中心とする円弧に沿って設けられた一対の仰角ラック16と、回転連結部材4の上下回転機構部7に設けられて一対の仰角ラック16に沿って移動しながら順次弾力的に係止される一対の仰角弾性突起17と、を備えているので、上下回転機構部7の一対の弾性軸部10を一対の支持突起部12の各軸受部9に嵌合させる際に、一対の仰角ラック16に一対の仰角弾性突起17を係合させることができ、これにより別部品を必要とせずに、簡単にかつ容易に仰角調整機構14を容易に組み立てることができる。
