Description

本発明は、ディスプレイ装置を姿勢変更可能に支持するディスプレイ支持装置の技術に関する。 The present invention relates to a technology of a display support device that supports a display device so that its posture can be changed.

従来、テレビジョンやパーソナルコンピュータ等のディスプレイ装置を姿勢変更可能に支持する装置は公知となっている。そして、このようなディスプレイ装置を支持する装置において、ディスプレイ装置の画像表示面の角度を変更可能とする技術は、例えば特許文献１により開示されている。 2. Description of the Related Art Conventionally, a device that supports a display device such as a television or a personal computer so that its posture can be changed is known. And in the apparatus which supports such a display apparatus, the technique which can change the angle of the image display surface of a display apparatus is disclosed by patent document 1, for example.

特許文献１に記載のディスプレイ支持装置（テレビスタンド）は、ディスプレイ装置（テレビ）を下部で支持するものであり、床や机等に載置されるベース部材（台部）と、このベース部材に取り付けられる柱部材（ベースブラケット）と、この柱部材に対して傾斜角度（チルト角度）を変更する方向に傾動可能に取り付けられるとともに、前記ディスプレイ支持装置が取り付けられる傾動プレートと、前記柱部材に対する前記傾動プレートのチルト角度を調節するチルトアジャスト機構とから構成されている。

しかし、前記ディスプレイ装置の画像表示面の角度を変更した場合、姿勢を変更する前後でディスプレイ装置の重心が大きくずれてしまうという問題があった。例えば、ベース部材の前後方向を定めた場合、前記ディスプレイ装置の画像表示面の上部をベース部材の後方向へ、下部をベース部材の前方向へ傾動させると、ディスプレイ装置の重心はベース部材の後方向へずれることとなる。そのため、ベース部材を後方向へ延設することによりディスプレイ装置の転倒を防止することが必要であった。
ところが、近年のディスプレイ装置の薄型化に伴って、ディスプレイ支持装置もまた、薄型のディスプレイ装置の有する省スペース性を損なわないコンパクトなものであることが望まれている。 However, when the angle of the image display surface of the display device is changed, there is a problem that the center of gravity of the display device is largely shifted before and after the posture is changed. For example, when the front-rear direction of the base member is determined, if the upper part of the image display surface of the display device is tilted rearward of the base member and the lower part is tilted forward of the base member, the center of gravity of the display device is Will shift in the direction. Therefore, it is necessary to prevent the display device from falling by extending the base member backward.
However, with the recent thinning of display devices, the display support device is also desired to be compact so as not to impair the space saving property of the thin display device.

そこで、本発明は係る課題に鑑み、ディスプレイ装置の角度を変更可能に支持する装置であって、コンパクトに設計することが可能なディスプレイ支持装置を提供する。 In view of the above problems, the present invention provides a display support device that supports the angle of the display device in a changeable manner and can be designed compactly.

なお、傾動シャフト４４・４４は本実施例では、支持部材３１と別体に設けたが、これに限定するものではなく、例えば、第一側面部４３と一体的に形成する構成とすることもできる。 Tilt shafts 44 and 44 for supporting the rotating member 32 are fixed to the first side surface portions 43 and 43, respectively. Two tilting shafts 44 and 44 are provided, and are penetrating from the holes provided in the first side surface portions 43 and 43 toward the outside of the support member 31. The portion inside the support member 31 and above the rotation shaft 13 forms a space for providing an urging member 61 described later.
In this embodiment, the tilting shafts 44 and 44 are provided separately from the support member 31. However, the tilting shafts 44 and 44 are not limited thereto. For example, the tilting shafts 44 and 44 may be formed integrally with the first side surface portion 43. it can.

回動部材３２は、ディスプレイ装置２に固定される第二主面部５１と、第二主面部５１の両側端から延設した第二側面部５２・５２と、から構成される。
第二主面部５１は、回動軸１３を中心にして第一主面部４２と水平方向に対向する位置に設けられる部分であり、言い換えれば、ディスプレイ装置２と同じ側に設けられた部分である。第二主面部５１の回動軸１３側と反対側の面にはディスプレイ装置２を取り付けるためのディスプレイ取付部材３３が設けられている。
第二側面部５２・５２は、第二主面部５１の両側端より、第二主面部５１と直交する方向であって第一側面部４３・４３の外側に重なる方向に設けられた二つの部分である。そして、各第二側面部５２・５２は、二本の傾動シャフト４４・４４によってそれぞれ軸支されている。このように構成することにより、回動部材３２は、支持部材３１に対してディスプレイ装置２の傾斜角度（チルト角度）を変更する方向に回動可能に軸支されることとなる。 The rotating member 32 includes a second main surface portion 51 fixed to the display device 2 and second side surface portions 52 and 52 extending from both side ends of the second main surface portion 51.
The second main surface portion 51 is a portion provided at a position facing the first main surface portion 42 in the horizontal direction around the rotation shaft 13, in other words, a portion provided on the same side as the display device 2. .

The second side surface portions 52 and 52 are two portions provided in a direction perpendicular to the second main surface portion 51 and overlapping the outside of the first side surface portions 43 and 43 from both side ends of the second main surface portion 51. It is. And each 2nd side part 52 * 52 is each supported by the two tilting shafts 44 * 44. With such a configuration, the rotation member 32 is pivotally supported so as to be rotatable in a direction in which the tilt angle (tilt angle) of the display device 2 is changed with respect to the support member 31.

板カム１５は、図５に示すように、平面視略楕円形状の板状部材である。板カム１５は上下一対の板面、および当該一対の板面に連なる外周面を有する。板カム１５には上下一対の板面を貫通するネジ孔が形成され、当該ネジ孔に回動軸１３が螺合する。板カム１５に形成されるネジ孔は板カム１５の平面視中央部よりも若干前方にずれた位置に形成される。
図４に示すように、板カム１５は回動軸１３の頭部１３ｂに当接する位置までネジ込まれる形で螺装されているため、回動軸１３において支持部材３１の下面部４１より上方へ突出した部分に固定されることとなる。このように構成することにより、板カム１５は支持部材３１の内部に設けられるため、省スペース化を図ることができ、デザイン性も向上する。
また、図５に示すように、板カム１５の外周面の後端部から板カム１５に螺装された回動軸１３の中心までの長さ（板カム１５の後方向の半径ｒ１）は、板カム１５の外周面の前端部から板カム１５に螺装された回動軸１３の中心までの長さ（板カム１５の前方向の半径ｒ２）よりも長い。 As shown in FIG. 5, the plate cam 15 is a plate-like member having a substantially elliptical shape in plan view. The plate cam 15 has a pair of upper and lower plate surfaces and an outer peripheral surface continuous to the pair of plate surfaces. The plate cam 15 is formed with a screw hole penetrating a pair of upper and lower plate surfaces, and the rotating shaft 13 is screwed into the screw hole. The screw hole formed in the plate cam 15 is formed at a position slightly shifted forward from the central portion of the plate cam 15 in plan view.
As shown in FIG. 4, since the plate cam 15 is screwed in such a manner that it is screwed to a position where it abuts against the head 13 b of the rotating shaft 13, the plate cam 15 is above the lower surface portion 41 of the supporting member 31. It will be fixed to the protruding part. By configuring in this way, the plate cam 15 is provided inside the support member 31, so that space can be saved and design is improved.
Further, as shown in FIG. 5, the length from the rear end portion of the outer peripheral surface of the plate cam 15 to the center of the rotating shaft 13 screwed to the plate cam 15 (the radius r1 in the rear direction of the plate cam 15) is The length from the front end portion of the outer peripheral surface of the plate cam 15 to the center of the rotating shaft 13 screwed to the plate cam 15 (the radius r2 in the forward direction of the plate cam 15) is longer.

付勢部材６１は回動部材３２の回動中心よりも下方の部分が板カム１５へ当接する方向に回動するように付勢するものである。
本実施形態の付勢部材６１は圧縮バネからなり、支持部材３１の内部（第一主面部４２と第二主面部５１との間）に配置される。付勢部材６１の一端部は第一主面部４２に当接し、付勢部材６１の他端部は第二主面部５１の上半部に当接する。
従って、付勢部材６１は弾性力により回動部材３２を支持部材３１に対して下方に回動する方向に付勢する。その結果、回動部材３２の下半部（本実施形態では、第二主面部５１の下半部の板面）が板カム１５の外周面に当接することとなる。
回動部材３２の下半部が板カム１５の外周面に当接することにより、支持部材３１に対する回動部材３２の回動角度、ひいては、回動部材３２に固定されるディスプレイ装置２の姿勢（ディスプレイ装置２の画像表示面の角度）が保持される。 The urging member 61 urges the portion below the rotation center of the rotation member 32 to rotate in a direction in which the plate member 15 contacts the plate cam 15.
The urging member 61 of the present embodiment is formed of a compression spring and is disposed inside the support member 31 (between the first main surface portion 42 and the second main surface portion 51). One end portion of the urging member 61 abuts on the first main surface portion 42, and the other end portion of the urging member 61 abuts on the upper half portion of the second main surface portion 51.
Therefore, the urging member 61 urges the rotating member 32 in the direction of rotating downward with respect to the support member 31 by the elastic force. As a result, the lower half of the rotating member 32 (in this embodiment, the plate surface of the lower half of the second main surface portion 51) comes into contact with the outer peripheral surface of the plate cam 15.
When the lower half of the rotating member 32 abuts on the outer peripheral surface of the plate cam 15, the rotating angle of the rotating member 32 with respect to the support member 31, and consequently the attitude of the display device 2 fixed to the rotating member 32 ( The angle of the image display surface of the display device 2 is maintained.

次に、ディスプレイ装置２の傾動角度を調整する際における各部材の位置の変化について、図７及び図８を用いて説明する。
図７（ａ）に示すように、ディスプレイ装置２が前方寄りにある場合には、板カム１５の外周面の前端部（回動軸１３中心までの距離が短い半径ｒ２である部分）と、回動部材３２の第二主面部５１の回動中心よりも下方の部分とが当接している。この状態では、ディスプレイ取付部材３３に固定されるディスプレイ装置２の画像表示面は略前方を向いている。
この場合、図８（ａ）に示すように、ディスプレイ装置２は柱部材１２よりも前方に配置されるため、ディスプレイ装置２の重心は柱部材１２よりも前方に配置され、ディスプレイ装置２の自重により柱部材１２とベース部材１１との固定部には柱部材１２を前方に倒す向きの力（図８（ａ）の矢印方向の力）が作用する。
しかし、柱部材１２はベース部材１１の後方寄りとなる位置に固定されているため、ベース部材１１において柱部材１２よりも前方となる部分が踏ん張り、ディスプレイ装置２およびこれを支持するディスプレイ支持装置１が転倒することはない。 Next, changes in the position of each member when adjusting the tilt angle of the display device 2 will be described with reference to FIGS. 7 and 8.
As shown in FIG. 7A, when the display device 2 is closer to the front, the front end portion of the outer peripheral surface of the plate cam 15 (the portion having a short radius r2 to the center of the rotation shaft 13), A portion below the rotation center of the second main surface portion 51 of the rotation member 32 is in contact with the portion. In this state, the image display surface of the display device 2 fixed to the display mounting member 33 faces substantially forward.
In this case, as shown in FIG. 8A, since the display device 2 is disposed in front of the column member 12, the center of gravity of the display device 2 is disposed in front of the column member 12, and the display device 2 has its own weight. As a result, a force in the direction of tilting the column member 12 forward (force in the direction of the arrow in FIG. 8A) acts on the fixed portion between the column member 12 and the base member 11.
However, since the column member 12 is fixed at a position closer to the rear of the base member 11, the portion of the base member 11 that is in front of the column member 12 is strung, and the display device 2 and the display support device 1 that supports the display device 2 are supported. Will never fall.

また、図７（ｂ）に示すように、ディスプレイ固定部材１４を柱部材１２に対して図７（ａ）に示す状態から１８０度回動した場合には、板カム１５の外周面の後端部（回動軸１３中心までの距離が長い半径ｒ１である部分）と、回動部材３２の第二主面部５１の回動中心よりも下方の部分とが当接している。この状態では、ディスプレイ取付部材３３に固定されるディスプレイ装置２の画像表示面は後方かつ図７（ａ）に示す状態よりも上方を向いている。
この場合、図８（ｂ）に示すように、ディスプレイ装置２の下端部は柱部材１２よりも後方に配置されるが、ディスプレイ装置２の上端部は柱部材１２の上方、あるいは柱部材１２よりも前方に配置されるため、ディスプレイ装置２の重心は前後方向において柱部材１２と同じ位置または柱部材１２よりも前方に配置され、ディスプレイ装置２の自重により柱部材１２とベース部材１１との固定部には柱部材１２を前方に倒す向きの力（図８（ｂ）の矢印方向の力）が作用する。
しかし、柱部材１２はベース部材１１の後方寄りとなる位置に固定されているため、ベース部材１１において柱部材１２よりも前方となる部分が踏ん張り、ディスプレイ装置２およびこれを支持するディスプレイ支持装置１が転倒することはない。 7B, when the display fixing member 14 is rotated 180 degrees from the state shown in FIG. 7A with respect to the column member 12, the rear end of the outer peripheral surface of the plate cam 15 The portion (the portion whose radius r1 is a long distance to the center of the rotation shaft 13) is in contact with the portion below the rotation center of the second main surface portion 51 of the rotation member 32. In this state, the image display surface of the display device 2 fixed to the display mounting member 33 faces rearward and upward from the state shown in FIG.
In this case, as shown in FIG. 8B, the lower end portion of the display device 2 is arranged behind the column member 12, but the upper end portion of the display device 2 is above the column member 12 or from the column member 12. Since the center of gravity of the display device 2 is arranged at the same position as the column member 12 or in front of the column member 12 in the front-rear direction, the column member 12 and the base member 11 are fixed by the weight of the display device 2. A force (the force in the direction of the arrow in FIG. 8B) in the direction of tilting the column member 12 forward acts on the portion.
However, since the column member 12 is fixed at a position closer to the rear of the base member 11, the portion of the base member 11 that is in front of the column member 12 is strung, and the display device 2 and the display support device 1 that supports the display device 2 are supported. Will never fall.

このように、図８（ａ）および図８（ｂ）のいずれの状態においても、ベース部材１１において柱部材１２よりも前方となる部分が踏ん張ることにより、ディスプレイ装置２およびこれを支持するディスプレイ支持装置１の転倒が防止される。
また、ベース部材１１においてディスプレイ装置２およびこれを支持するディスプレイ支持装置１の転倒防止に寄与する部分は主として柱部材１２よりも前方となる部分であるため、ベース部材１１において柱部材１２よりも前方となる部分を後方に大きく伸ばす必要がなく、全体としてはベース部材１１の前後方向の長さを抑えることが可能である。 As described above, in both the states of FIG. 8A and FIG. 8B, the display device 2 and the display support that supports the display device 2 are supported by straddling the portion of the base member 11 that is in front of the column member 12. The device 1 is prevented from falling.
Further, in the base member 11, the portion that contributes to the prevention of the overturn of the display device 2 and the display support device 1 that supports the display device 2 is mainly the front portion of the column member 12. Therefore, the length of the base member 11 in the front-rear direction can be suppressed as a whole.

また、図５及び図６に示すように、ディスプレイ支持装置１は、ディスプレイ固定部材１４の水平方向の回動を所定角度許容してそれ以上の回動を規制する回動規制機構７１を具備する。
回動規制機構７１は、支持部材３１が回動軸１３に軸支されたときに互いに回動軸１３を中心として１８０度位相がずれた一対の略円弧状の回動規制孔７２・７２と、柱部材１２に上下方向に摺動可能に支持される回動規制突起７３と、から構成される。また、回動軸固定面１２ｂの中心からどちらか一方の側方にずれた位置に、回動規制突起７３を貫通させるための孔が設けられている。
また回動規制突起７３は、柱部材１２の中途部に設けた摺動操作部材７４と連結しており、摺動操作部材７４を操作することにより、回動規制突起７３は上下方向（図６の矢印方向）に摺動する。回動規制突起７３が上方向に摺動した場合には、一対の回動規制孔７２・７２のいずれかに貫装された状態となる。また、回動規制突起７３が下方向に摺動した場合には、一対の回動規制孔７２・７２のいずれにも貫装されない状態となる。 As shown in FIGS. 5 and 6, the display support device 1 includes a rotation restricting mechanism 71 that allows the display fixing member 14 to rotate in the horizontal direction by a predetermined angle and restricts further rotation. .
The rotation restricting mechanism 71 includes a pair of substantially arc-shaped rotation restricting holes 72 and 72 that are 180 degrees out of phase with respect to the rotation shaft 13 when the support member 31 is supported on the rotation shaft 13. The rotation restricting protrusion 73 is supported by the column member 12 so as to be slidable in the vertical direction. In addition, a hole for allowing the rotation restricting protrusion 73 to pass therethrough is provided at a position shifted to either one side from the center of the rotation shaft fixing surface 12b.
Further, the rotation restricting projection 73 is connected to a sliding operation member 74 provided in the middle of the column member 12, and by operating the sliding operation member 74, the rotation restricting projection 73 is moved in the vertical direction (FIG. 6). Slide in the direction of the arrow. When the rotation restricting protrusion 73 slides upward, the rotation restricting protrusion 73 is inserted into one of the pair of turn restricting holes 72 and 72. In addition, when the rotation restricting protrusion 73 slides downward, the rotation restricting protrusion 73 is not inserted into any of the pair of turn restricting holes 72 and 72.

回動規制突起７３が回動規制孔７２のいずれかに貫装された状態の場合、ディスプレイ固定部材１４が回動しようとしても回動規制孔７２の両端と回動規制突起７３とが接触することとなり、それ以上の回動を規制するものである。このように構成することにより、ディスプレイ装置２の水平方向の回動を所定角度許容しつつ規制することができる。
また、ディスプレイ固定部材１４を柱部材１２に対して図７（ａ）に示す状態から１８０度回動した場合には、回動規制突起７３を下方に摺動させる。これにより、回動規制が解除される。また、ディスプレイ固定部材１４を柱部材１２に対して図７（ａ）に示す状態から１８０度回動した場合には、回動規制突起７３を上方に摺動させる。これにより、回動規制突起７３がもう一方の回動規制孔７２に貫装されることにより、ディスプレイ固定部材１４の回動を規制することができる。 When the rotation restricting protrusion 73 is inserted into any of the turn restricting holes 72, both ends of the turn restricting hole 72 and the turn restricting protrusion 73 come into contact with each other even if the display fixing member 14 tries to rotate. That is, further rotation is restricted. With this configuration, the horizontal rotation of the display device 2 can be restricted while allowing a predetermined angle.
When the display fixing member 14 is rotated 180 degrees from the state shown in FIG. 7A with respect to the column member 12, the rotation restricting protrusion 73 is slid downward. Thereby, rotation regulation is cancelled | released. When the display fixing member 14 is rotated 180 degrees from the state shown in FIG. 7A with respect to the column member 12, the rotation restricting protrusion 73 is slid upward. Accordingly, the rotation of the display fixing member 14 can be restricted by inserting the rotation restricting protrusion 73 into the other rotation restricting hole 72.

なお、回動規制機構７１は、本実施例においては、回動規制孔７２と回動規制突起７３とで構成したが、これに限定するものではなく、例えば、ディスプレイ固定部材１４側に上下摺動可能な突起を設け、柱部材１２側に所定の幅のある孔を設けて、前記突起を孔から突出させることにより回動を規制することも可能である。 In the present embodiment, the rotation restricting mechanism 71 is composed of the rotation restricting hole 72 and the rotation restricting protrusion 73. However, the present invention is not limited to this. It is also possible to restrict the rotation by providing a movable projection, providing a hole having a predetermined width on the column member 12 side, and projecting the projection from the hole.

＜第二実施形態＞
また、図９に示すように、付勢部材６１を設ける代わりに、板カム１５の上面に板カム１５の外周面からの距離を一定に保持しつつ板カム１５の外周面に沿って伸びたリング状の係合溝１５ａを形成し、回動部材３２に、係合溝１５ａに係合する係合突起１０１を形成する構成とすることもできる。ディスプレイ支持装置１のその他の構成は、第一実施形態と同様であるので省略する。
係合溝１５ａは、板カム１５の上面に板カム１５の外周面からの距離を一定に保持しつつ板カム１５の外周面に沿って伸びたリング状に形成されており、図９（ａ）に示すように、係合突起１０１に設けた係合部１０１ａの長さと略同じ深さで穿設されている。係合溝１５ａは、本実施例においては断面視略四角形状に形成されているが、これに限定するものではなく、係合部１０１ａの形状と合わせて形成することもできる。例えば係合部１０１ａを半球状に構成して、係合溝１５ａを断面視半円状に構成することもできる。
係合突起１０１は回動部材３２の第二主面部５１の下半部に形成されている。第二主面部５１と係合突起１０１とは、溶接や、螺子等の連結部材によって連結されている。
このように構成することにより、板カム１５と回動部材３２の下端との間は、係合突起１０１の長さ分の距離を保つ。
より詳細には、ディスプレイ固定部材１４が柱部材１２に対して水平方向に回動される場合にも、係合突起１０１の係合部１０１ａが板カム１５の係合溝１５ａに係合しつつ回動するため、板カム１５と回動部材３２の下端との間は、常に係合突起１０１の長さ分の距離を保つこととなる。
また、回動部材３２の回動中心である傾動シャフト４４よりも下方の部分が板カム１５から離れる方向へ傾動しようとした場合であっても、その傾動を規制することができる。 <Second embodiment>
Further, as shown in FIG. 9, instead of providing the urging member 61, the upper surface of the plate cam 15 extends along the outer peripheral surface of the plate cam 15 while keeping the distance from the outer peripheral surface of the plate cam 15 constant. A ring-shaped engaging groove 15a may be formed, and the engaging protrusion 101 that engages with the engaging groove 15a may be formed on the rotating member 32. Since the other structure of the display support apparatus 1 is the same as that of 1st embodiment, it abbreviate | omits.
The engagement groove 15a is formed in a ring shape extending along the outer peripheral surface of the plate cam 15 while maintaining a constant distance from the outer peripheral surface of the plate cam 15 on the upper surface of the plate cam 15. FIG. As shown in FIG. 5B, the depth is substantially the same as the length of the engaging portion 101a provided on the engaging protrusion 101. In this embodiment, the engaging groove 15a is formed in a substantially quadrangular shape in cross section. However, the engaging groove 15a is not limited to this and can be formed in accordance with the shape of the engaging portion 101a. For example, the engaging portion 101a can be formed in a hemispherical shape, and the engaging groove 15a can be formed in a semicircular shape in cross section.
The engaging protrusion 101 is formed on the lower half of the second main surface portion 51 of the rotating member 32. The 2nd main surface part 51 and the engagement protrusion 101 are connected by connection members, such as welding and a screw.
With this configuration, a distance corresponding to the length of the engaging protrusion 101 is maintained between the plate cam 15 and the lower end of the rotating member 32.
More specifically, even when the display fixing member 14 is rotated in the horizontal direction with respect to the column member 12, the engaging portion 101 a of the engaging protrusion 101 is engaged with the engaging groove 15 a of the plate cam 15. Therefore, the distance between the plate cam 15 and the lower end of the rotating member 32 is always kept at a distance corresponding to the length of the engaging protrusion 101.
Further, even when a portion below the tilt shaft 44 that is the rotation center of the rotation member 32 is inclined in a direction away from the plate cam 15, the tilt can be restricted.

次に、ディスプレイ装置２の傾動角度を調整する際における各部材の位置の変化について、図９（ａ）及び図９（ｂ）を用いて説明する。
図９（ａ）に示すように、ディスプレイ装置２が前方寄りにある場合には、係合突起１０１の係合部１０１ａは板カム１５に設けられた係合溝１５ａの前端部（回動軸１３中心からの距離が短い半径ｒ２である部分に対応する部分）と係合する。この状態では、ディスプレイ取付部材３３に固定されるディスプレイ装置２の画像表示面は略前方を向いている。
この場合、図８（ａ）に示すように、ディスプレイ装置２は柱部材１２よりも前方に配置されるため、ディスプレイ装置２の重心は柱部材１２よりも前方に配置され、ディスプレイ装置２の自重により柱部材１２とベース部材１１との固定部には柱部材１２を前方に倒す向きの力（図８（ａ）の矢印方向の力）が作用する。
しかし、柱部材１２はベース部材１１の後方寄りとなる位置に固定されているため、ベース部材１１において柱部材１２よりも前方となる部分が踏ん張り、ディスプレイ装置２およびこれを支持するディスプレイ支持装置１が転倒することはない。 Next, changes in the position of each member when adjusting the tilt angle of the display device 2 will be described with reference to FIGS. 9A and 9B.
As shown in FIG. 9A, when the display device 2 is closer to the front, the engaging portion 101 a of the engaging protrusion 101 is the front end portion (rotating shaft) of the engaging groove 15 a provided in the plate cam 15. 13 is engaged with a portion corresponding to a portion having a short radius r2 from the center. In this state, the image display surface of the display device 2 fixed to the display mounting member 33 faces substantially forward.
In this case, as shown in FIG. 8A, since the display device 2 is disposed in front of the column member 12, the center of gravity of the display device 2 is disposed in front of the column member 12, and the display device 2 has its own weight. As a result, a force in the direction of tilting the column member 12 forward (force in the direction of the arrow in FIG. 8A) acts on the fixed portion between the column member 12 and the base member 11.
However, since the column member 12 is fixed at a position closer to the rear of the base member 11, the portion of the base member 11 that is in front of the column member 12 is strung, and the display device 2 and the display support device 1 that supports the display device 2 are supported. Will never fall.

また、図９（ｂ）に示すように、ディスプレイ固定部材１４を柱部材１２に対して図９（ａ）に示す状態から１８０度回動した場合には、係合突起１０１の係合部１０１ａは板カム１５に設けられた係合溝１５ａの後端部（回動軸１３中心からの距離が長い半径ｒ１である部分に対応する部分）と係合する。この状態では、ディスプレイ取付部材３３に固定されるディスプレイ装置２の画像表示面は後方かつ図９（ａ）に示す状態よりも上方を向いている。
この場合、図８（ｂ）に示すように、ディスプレイ装置２の下端部は柱部材１２よりも後方に配置されるが、ディスプレイ装置２の上端部は柱部材１２の上方、あるいは柱部材１２よりも前方に配置されるため、ディスプレイ装置２の重心は前後方向において柱部材１２と同じ位置または柱部材１２よりも前方に配置され、ディスプレイ装置２の自重により柱部材１２とベース部材１１との固定部には柱部材１２を前方に倒す向きの力（図８（ｂ）の矢印方向の力）が作用する。
しかし、柱部材１２はベース部材１１の後方寄りとなる位置に固定されているため、ベース部材１１において柱部材１２よりも前方となる部分が踏ん張り、ディスプレイ装置２およびこれを支持するディスプレイ支持装置１が転倒することはない。 Further, as shown in FIG. 9B, when the display fixing member 14 is rotated 180 degrees from the state shown in FIG. 9A with respect to the column member 12, the engaging portion 101a of the engaging protrusion 101 is obtained. Engages with the rear end portion of the engagement groove 15a provided in the plate cam 15 (the portion corresponding to the portion having the radius r1 that is long from the center of the rotation shaft 13). In this state, the image display surface of the display device 2 fixed to the display mounting member 33 faces rearward and upward from the state shown in FIG.
In this case, as shown in FIG. 8B, the lower end portion of the display device 2 is arranged behind the column member 12, but the upper end portion of the display device 2 is above the column member 12 or from the column member 12. Since the center of gravity of the display device 2 is arranged at the same position as the column member 12 or in front of the column member 12 in the front-rear direction, the column member 12 and the base member 11 are fixed by the weight of the display device 2. A force (the force in the direction of the arrow in FIG. 8B) in the direction of tilting the column member 12 forward acts on the portion.
However, since the column member 12 is fixed at a position closer to the rear of the base member 11, the portion of the base member 11 that is in front of the column member 12 is strung, and the display device 2 and the display support device 1 that supports the display device 2 are supported. Will never fall.

＜第三実施形態＞
また、図１０に示すように、付勢部材６１を設ける代わりに、板カム１５の外周面に当該外周面の長手方向に伸びるとともに開口部よりも奥部が広がった断面形状を有する側面溝１５ｂを形成し、回動部材３２に、側面溝１５ｂの奥部に脱落不能に嵌合する嵌合部２０１ａを有する嵌合突起２０１を形成する構成とすることもできる。ディスプレイ支持装置１のその他の構成は、前記第一実施形態と同様であるので省略する。
側面溝１５ｂは、図１０（ａ）に示すように、板カム１５の上下一対の板面に連なる外周面の長手方向に伸びるとともに開口部よりも奥部が広がった断面形状を有するものである。側面溝１５ｂは、板カム１５を上下方向二分割し、上半部及び下半部それぞれの分割面に、断面形状のうち上下方向二分割されたうちの半分の形状を穿設して設ける。例えば、図１０（ａ）に示すように，側面溝１５ｂが、開口部を断面視台形状に、奥部を断面視円形状に形成した断面形状を有する場合には、上半部及び下半部それぞれの分割面に断面視半円と台形を組み合わせた形状の溝を穿設して設ける。また、側面溝１５ｂの断面視円形状に形成された部分は嵌合突起２０１の嵌合部２０１ａが内接し、側面溝１５ｂの断面視台形状に形成された部分は、嵌合突起２０１が上下方向に傾動した際であっても側面溝１５ｂに接触しない程度の大きさで形成されている。
嵌合突起２０１は回動部材３２の第二主面部５１下半部に形成されている。嵌合突起２０１と第二主面部下半部との間には嵌合突起回動軸２０２が設けられており、嵌合突起２０１は嵌合突起回動軸２０２を中心として上下方向に回動可能に連結されている。 <Third embodiment>
Further, as shown in FIG. 10, instead of providing the biasing member 61, a side groove 15 b having a cross-sectional shape that extends in the longitudinal direction of the outer peripheral surface of the plate cam 15 and has a deeper portion than the opening. It is also possible to form the fitting protrusion 201 having the fitting portion 201a that fits in the inner portion of the side groove 15b so as not to drop off. Since the other structure of the display support apparatus 1 is the same as that of said 1st embodiment, it abbreviate | omits.
As shown in FIG. 10A, the side groove 15b has a cross-sectional shape that extends in the longitudinal direction of the outer peripheral surface connected to the pair of upper and lower plate surfaces of the plate cam 15 and has a deeper portion than the opening. . The side groove 15b is provided by dividing the plate cam 15 into two parts in the vertical direction, and by piercing each of the upper half part and the lower half part with a half of the cross-sectional shape divided in the vertical direction. For example, as shown in FIG. 10 (a), when the side groove 15b has a cross-sectional shape in which the opening is formed in a trapezoidal shape in cross section and the back is formed in a circular shape in cross section, the upper half and the lower half are formed. A groove having a combination of a semicircle and a trapezoid in a sectional view is formed on each divided surface. Further, the portion of the side groove 15b that is formed in a circular shape in cross section is inscribed by the fitting portion 201a of the fitting protrusion 201, and the portion of the side groove 15b that is formed in a trapezoidal shape in cross section is Even when tilted in the direction, it is formed in such a size that it does not contact the side groove 15b.
The fitting protrusion 201 is formed on the lower half of the second main surface portion 51 of the rotating member 32. A fitting protrusion rotation shaft 202 is provided between the fitting protrusion 201 and the lower half of the second main surface portion, and the fitting protrusion 201 rotates in the vertical direction around the fitting protrusion rotation shaft 202. Connected as possible.

このように構成することにより、板カム１５と回動部材３２の下端との間は、嵌合突起２０１の長さ分の距離を保つこととなり、支持部材３１に対する回動部材３２の回動角度、ひいては、回動部材３２に固定されるディスプレイ装置２の姿勢（ディスプレイ装置２の画像表示面の角度）が保持される。
より詳細には、ディスプレイ固定部材１４が柱部材１２に対して水平方向に回動される場合にも、嵌合突起２０１の嵌合部２０１ａが板カム１５の側面溝１５ｂに嵌合しつつ回動するため、板カム１５と回動部材３２の下端との間は、常に嵌合突起２０１の長さ分の距離を保つこととなる。また、回動部材３２の回動中心である傾動シャフト４４よりも下方の部分が板カム１５から離れる方向へ傾動しようとした場合であっても、その傾動を規制することができる。
また、ディスプレイ固定部材１４が柱部材１２に対して水平方向に回動される場合に、回動部材３２の傾動に合わせて嵌合突起２０１が上方に傾動した場合であっても、側面溝１５ｂと嵌合突起２０１とが接触して回動を阻害することがない。 With this configuration, a distance corresponding to the length of the fitting protrusion 201 is maintained between the plate cam 15 and the lower end of the rotation member 32, and the rotation angle of the rotation member 32 with respect to the support member 31. As a result, the attitude of the display device 2 fixed to the rotating member 32 (the angle of the image display surface of the display device 2) is maintained.
More specifically, even when the display fixing member 14 is rotated in the horizontal direction with respect to the column member 12, the fitting portion 201 a of the fitting protrusion 201 is rotated while fitting into the side groove 15 b of the plate cam 15. Therefore, a distance corresponding to the length of the fitting protrusion 201 is always maintained between the plate cam 15 and the lower end of the rotating member 32. Further, even when a portion below the tilt shaft 44 that is the rotation center of the rotation member 32 is inclined in a direction away from the plate cam 15, the tilt can be restricted.
Further, when the display fixing member 14 is rotated in the horizontal direction with respect to the column member 12, even when the fitting protrusion 201 is tilted upward in accordance with the tilting of the rotating member 32, the side groove 15 b. And the fitting protrusion 201 are not in contact with each other to prevent rotation.

次に、ディスプレイ装置２の傾動角度を調整する際における各部材の位置の変化について、図１０（ａ）及び図１０（ｂ）を用いて説明する。
図１０（ａ）に示すように、ディスプレイ装置２が前方寄りにある場合には、嵌合突起２０１の嵌合部２０１ａは、板カム１５に設けられた側面溝１５ｂの前端部（回動軸１３中心からの距離が短い半径ｒ２である部分に対応する部分）と嵌合する。この状態では、ディスプレイ取付部材３３に固定されるディスプレイ装置２の画像表示面は略前方を向いている。
この場合、図８（ａ）に示すように、ディスプレイ装置２は柱部材１２よりも前方に配置されるため、ディスプレイ装置２の重心は柱部材１２よりも前方に配置され、ディスプレイ装置２の自重により柱部材１２とベース部材１１との固定部には柱部材１２を前方に倒す向きの力（図８（ａ）の矢印方向の力）が作用する。
しかし、柱部材１２はベース部材１１の後方寄りとなる位置に固定されているため、ベース部材１１において柱部材１２よりも前方となる部分が踏ん張り、ディスプレイ装置２およびこれを支持するディスプレイ支持装置１が転倒することはない。 Next, changes in the position of each member when adjusting the tilt angle of the display device 2 will be described with reference to FIGS. 10 (a) and 10 (b).
As shown in FIG. 10A, when the display device 2 is closer to the front, the fitting portion 201a of the fitting protrusion 201 is the front end portion (rotating shaft) of the side groove 15b provided in the plate cam 15. 13 and a portion corresponding to a portion having a short radius r2 from the center). In this state, the image display surface of the display device 2 fixed to the display mounting member 33 faces substantially forward.
In this case, as shown in FIG. 8A, since the display device 2 is disposed in front of the column member 12, the center of gravity of the display device 2 is disposed in front of the column member 12, and the display device 2 has its own weight. As a result, a force in the direction of tilting the column member 12 forward (force in the direction of the arrow in FIG. 8A) acts on the fixed portion between the column member 12 and the base member 11.
However, since the column member 12 is fixed at a position closer to the rear of the base member 11, the portion of the base member 11 that is in front of the column member 12 is strung, and the display device 2 and the display support device 1 that supports the display device 2 are supported. Will never fall.

また、図１０（ｂ）に示すように、ディスプレイ固定部材１４を柱部材１２に対して図１０（ａ）に示す状態から１８０度回動した場合には、嵌合突起２０１の嵌合部２０１ａは板カム１５に設けられた側面溝１５ｂの後端部（回動軸１３中心からの距離が長い半径ｒ１である部分に対応する部分）と嵌合する。この状態では、ディスプレイ取付部材３３に固定されるディスプレイ装置２の画像表示面は後方かつ図１０（ａ）に示す状態よりも上方を向いている。
この場合、図８（ｂ）に示すように、ディスプレイ装置２の下端部は柱部材１２よりも後方に配置されるが、ディスプレイ装置２の上端部は柱部材１２の上方、あるいは柱部材１２よりも前方に配置されるため、ディスプレイ装置２の重心は前後方向において柱部材１２と同じ位置または柱部材１２よりも前方に配置され、ディスプレイ装置２の自重により柱部材１２とベース部材１１との固定部には柱部材１２を前方に倒す向きの力が作用する。
しかし、柱部材１２はベース部材１１の後方寄りとなる位置に固定されているため、ベース部材１１において柱部材１２よりも前方となる部分が踏ん張り、ディスプレイ装置２およびこれを支持するディスプレイ支持装置１が転倒することはない。 Further, as shown in FIG. 10B, when the display fixing member 14 is rotated 180 degrees from the state shown in FIG. 10A with respect to the column member 12, the fitting portion 201a of the fitting protrusion 201 is obtained. Is fitted to the rear end portion of the side groove 15b provided in the plate cam 15 (the portion corresponding to the portion having the radius r1 that is long from the center of the rotation shaft 13). In this state, the image display surface of the display device 2 fixed to the display mounting member 33 faces rearward and upward from the state shown in FIG.
In this case, as shown in FIG. 8B, the lower end portion of the display device 2 is arranged behind the column member 12, but the upper end portion of the display device 2 is above the column member 12 or from the column member 12. Since the center of gravity of the display device 2 is arranged at the same position as the column member 12 or in front of the column member 12 in the front-rear direction, the column member 12 and the base member 11 are fixed by the weight of the display device 2. A force in the direction of tilting the column member 12 forward acts on the portion.
However, since the column member 12 is fixed at a position closer to the rear of the base member 11, the portion of the base member 11 that is in front of the column member 12 is strung, and the display device 2 and the display support device 1 that supports the display device 2 are supported. Will never fall.
