Description

【0001】
【発明の属する技術分野】
本発明は旋回構造物の支持装置に関するものである。
【0002】
【従来の技術】
照明器具、あるいはパソコンのディスプレイ装置を所定の旋回軸周りに回転自在に支持する際に使用される支持装置の従来例を図6に示す。この従来例において、照明器具等(旋回構造物1)は旋回軸2と、旋回軸2に平行なガイド軸4とを有し、適宜手段により設置基部8に固定される支持装置9には、旋回軸2が挿通する軸支持部3と、ガイド軸4が挿通するガイド溝5が形成される。
【0003】
支持装置9に固定した状態で旋回構造物1は旋回軸2を中心として回転自在であり、ガイド溝5により回転角度θが規制される。
【0004】
【発明が解決しようとする課題】
しかし、上述した従来例において、旋回構造物1の旋回角度は支持装置9に予め形成されるガイド溝5により決定されるために、例えば、旋回範囲に壁面10等が干渉する場合には、干渉の発生しない範囲内に旋回構造物1の旋回角度を規制するようにガイド溝5を設計した支持装置9を別途用意する必要があり、汎用性に欠けるという問題がある。
【0005】
本発明は、以上の欠点を解消すべくなされたものであって、旋回構造物の旋回角度を自由に設定することのできるようにして汎用性を向上させた旋回構造物の支持装置を提供することを目的とする。
【0006】
【課題を解決するための手段】
支持装置9に装着された旋回構造物1は、旋回軸2とガイド軸4とが軸支持部3、およびガイド溝5に挿入されて旋回軸2周りに回転自在であり、ガイド溝5内でのガイド軸4の移動範囲によって旋回角度が規制される。
【0007】
ガイド溝5は、支持装置9に形成された閉塞部材取付部6に溝閉塞部材7を固定することにより任意の位置を閉塞できる。したがってこの発明において、ガイド溝5を任意に閉塞することによって旋回構造物1の回転角度を任意に設定できるために、汎用性が向上する。
【0008】
【発明の実施の形態】
図1にパソコンのディスプレイ装置(旋回構造物1)を壁面8に支持するための支持装置9を示す。ディスプレイ装置1は、液晶表示装置等により形成される表示部1aと、適数個の関節1b周りに屈曲操作自在な屈曲アーム1cとからなり、屈曲アーム1cの先端には、旋回軸2とガイド軸4が突設される。
【0009】
支持装置9は、ボックス形状をなす主体部9aと、主体部9aに着脱自在な閉塞板(溝閉塞部材7)とを有する。主体部9aは側壁部に形成される図外の固定部において壁面8に固定可能であり、主体部9aの上面に上記旋回軸2を支承する軸支持部3が形成される。軸支持部3はディスプレイ装置1側の旋回軸2を脱離不能、かつ、回転自在に挿通する単なる筒状体としても、あるいは、旋回軸2を連結、固定可能な回転軸としても形成できる。
【0010】
また、主体部9aの上面にはガイド軸4が嵌合可能なガイド溝5が形成される。ガイド溝5は、図2(a)に示すように、旋回軸2の回転に伴うガイド軸4の移動を許容するように、軸支持部3と同心の円弧形状をなす。
【0011】
さらに、上記ガイド溝5に沿って複数の閉塞板取付孔(閉塞部材取付部6)が形成される。閉塞板取付孔6は、ガイド溝5を所定ピッチ角度pで等分するピッチ線上において、ガイド溝5の内外方向に各々1個ずつ形成される。
【0012】
一方、閉塞板7は、図2(b)に示すように、上記ガイド溝5と同一曲率の円弧形状により形成され、一端が閉塞されたガイド軸通過切欠7aと、ガイド軸通過切欠7aに沿って形成される取付孔7bとを有する板状体で、図2(a)に示すように、取付孔7bを主体部9aの閉塞板取付孔6に合致させた状態でガイド軸通過切欠7aはガイド溝5に合致する。
【0013】
この閉塞板7の主体部9aへの固定は、種々の方法によることが可能であるが、例えば、図3(b)に示すように、合成樹脂製のリベット11を閉塞板取付孔6に圧入したり、あるいは、ねじ止めする方法によることができる。
【0014】
したがってこの実施の形態において、出荷時においては、図2(a)に示すように、閉塞板7をガイド溝5を閉塞しない終端位置に装着しておき、ディスプレイ装置1を設置した状態で、壁面等との当たりが発生する場合には、図4に示すように、一旦閉塞板7を取り外した後、適宜の位置に閉塞板7を固定し直すことによって、旋回角度をθからθ’に規制し、壁面等との当たりを簡単に防止できる。
【0015】
図5に本発明の他の実施の形態を示す。この実施の形態において、溝閉塞部材7は合成樹脂材により形成され、図5(a)〜(d)に示すように、上方に摘み部7cが突設された円板状の閉塞プレート部7dを有する。一方、ガイド溝5には所定ピッチで閉塞部材取付部6となる拡径部が形成され、閉塞プレート部7dは、拡径部6の径より大径に形成される。また、閉塞プレート部7dの裏面には、長軸寸法が上記拡径部6の直径よりやや長寸のストッパ長円部7eが形成され、該ストッパ長円部7eの裏面にさらに長円形状の底壁ストッパ7fが設けられる。
【0016】
ストッパ長円部7eの厚さ(h)は、主体部9aの天井部の肉厚にほぼ等しく、まず、図5(e)において、矢印Aで示すように、底壁ストッパ7fをガイド溝5に挿通させた後、摘み部7cを水平回転させると、図5(e)において矢印Bで示すように、ストッパ長円部7eが撓みながらガイド溝5の拡径部6に嵌合し、当該回転姿勢を維持する。この状態において、溝閉塞部材7は底壁ストッパ7fと閉塞プレート部7dにより主体部9aの天井部を挟み付けることからガイド溝5から脱落することがなくなり、この結果、ガイド軸4の移動範囲を規制する干渉体として機能する。
【0017】
なお、以上においては、1個の溝閉塞部材7を使用することにより、予め決定されたガイド溝5の一方の終端から溝閉塞部材7が装着される範囲までを旋回角度として規制する場合を示したが、2個の溝閉塞部材7を使用すると、両側の旋回終端を自由に決定することが可能になる。
【0018】
【発明の効果】
以上の説明から明らかなように、本発明によれば、旋回構造物の旋回角度を自由に設定することのできるので、汎用性を向上させることができる。

[0002]
[Prior art]
FIG. 6 shows a conventional example of a supporting device used to rotatably support a lighting device or a display device of a personal computer around a predetermined pivot axis. In this conventional example, a lighting device or the like (swirl structure 1) has a swivel shaft 2 and a guide shaft 4 parallel to the swivel shaft 2, and a supporting device 9 fixed to the installation base 8 by appropriate means includes: A shaft support portion 3 through which the turning shaft 2 is inserted and a guide groove 5 through which the guide shaft 4 is inserted are formed.
[0003]
The turning structure 1 is rotatable about the turning shaft 2 in a state of being fixed to the support device 9, and the rotation angle θ is regulated by the guide groove 5.
[0004]
[Problems to be solved by the invention]
However, in the conventional example described above, since the turning angle of the turning structure 1 is determined by the guide groove 5 formed in advance in the support device 9, for example, when the wall surface 10 or the like interferes with the turning range, It is necessary to separately prepare a supporting device 9 in which the guide groove 5 is designed so as to regulate the turning angle of the turning structure 1 within a range where the occurrence does not occur, and there is a problem that versatility is lacking.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-described drawbacks, and provides a swing structure support apparatus that can freely set a swing angle of the swing structure and has improved versatility. The purpose is to:
[0006]
[Means for Solving the Problems]
The turning structure 1 mounted on the support device 9 has the turning shaft 2 and the guide shaft 4 inserted into the shaft support portion 3 and the guide groove 5 so as to be rotatable around the turning shaft 2. The turning angle is restricted by the moving range of the guide shaft 4.
[0007]
The guide groove 5 can be closed at an arbitrary position by fixing the groove closing member 7 to the closing member mounting portion 6 formed on the support device 9. Therefore, in the present invention, since the rotation angle of the turning structure 1 can be arbitrarily set by arbitrarily closing the guide groove 5, versatility is improved.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a support device 9 for supporting a display device (swivel structure 1) of a personal computer on a wall surface 8. The display device 1 includes a display unit 1a formed by a liquid crystal display device and the like, and a bending arm 1c that can be bent around an appropriate number of joints 1b. The shaft 4 protrudes.
[0009]
The support device 9 includes a main body 9a having a box shape, and a closing plate (groove closing member 7) detachable from the main body 9a. The main body portion 9a can be fixed to the wall surface 8 at a fixing portion (not shown) formed on the side wall portion, and the shaft support portion 3 that supports the turning shaft 2 is formed on the upper surface of the main body portion 9a. The shaft support 3 can be formed as a simple cylindrical body through which the rotating shaft 2 on the display device 1 side cannot be detached and rotatably inserted, or can be formed as a rotating shaft to which the rotating shaft 2 can be connected and fixed.
[0010]
A guide groove 5 into which the guide shaft 4 can be fitted is formed on the upper surface of the main body 9a. As shown in FIG. 2A, the guide groove 5 has an arc shape concentric with the shaft support 3 so as to allow the movement of the guide shaft 4 accompanying the rotation of the turning shaft 2.
[0011]
Further, a plurality of closing plate mounting holes (closing member mounting portions 6) are formed along the guide grooves 5. One closing plate mounting hole 6 is formed in each of the inside and outside directions of the guide groove 5 on a pitch line equally dividing the guide groove 5 at a predetermined pitch angle p.
[0012]
On the other hand, as shown in FIG. 2 (b), the closing plate 7 is formed in an arc shape having the same curvature as the guide groove 5, and has a guide shaft passing notch 7a with one end closed and a guide shaft passing notch 7a. As shown in FIG. 2 (a), the guide shaft passage notch 7a is formed in a state in which the mounting hole 7b is aligned with the closing plate mounting hole 6 of the main body 9a, as shown in FIG. It matches the guide groove 5.
[0013]
The closure plate 7 can be fixed to the main body 9a by various methods. For example, as shown in FIG. 3B, a rivet 11 made of synthetic resin is pressed into the closure plate mounting hole 6. Or by screwing.
[0014]
Therefore, in this embodiment, at the time of shipping, as shown in FIG. 2A, the closing plate 7 is mounted at a terminal position where the guide groove 5 is not closed, and the wall surface is mounted with the display device 1 installed. In the case where a collision occurs, as shown in FIG. 4, the turning angle is restricted from θ to θ ′ by once removing the closing plate 7 and fixing the closing plate 7 at an appropriate position again. In addition, it is possible to easily prevent contact with a wall surface or the like.
[0015]
FIG. 5 shows another embodiment of the present invention. In this embodiment, the groove closing member 7 is formed of a synthetic resin material, and as shown in FIGS. 5A to 5D, a disk-shaped closing plate portion 7d having a knob 7c protruding upward. Having. On the other hand, the guide groove 5 is formed with a large-diameter portion serving as the closing member attaching portion 6 at a predetermined pitch, and the closing plate portion 7 d is formed to have a larger diameter than the diameter of the large-diameter portion 6. On the back surface of the closing plate portion 7d, there is formed a stopper oval portion 7e whose major axis is slightly longer than the diameter of the enlarged diameter portion 6, and a further oval shape is formed on the back surface of the stopper oval portion 7e. A bottom wall stopper 7f is provided.
[0016]
The thickness (h) of the stopper oval portion 7e is substantially equal to the thickness of the ceiling portion of the main portion 9a. First, as shown by an arrow A in FIG. When the knob 7c is rotated horizontally after insertion, the stopper oval portion 7e is fitted into the enlarged diameter portion 6 of the guide groove 5 while bending as shown by an arrow B in FIG. Maintain a rotating posture. In this state, since the groove closing member 7 sandwiches the ceiling of the main body 9a by the bottom wall stopper 7f and the closing plate portion 7d, the groove closing member 7 does not fall out of the guide groove 5, and as a result, the moving range of the guide shaft 4 is reduced. Acts as a restricting interferer.
[0017]
In the above description, a case is described in which the use of one groove closing member 7 restricts a turning angle from a predetermined one end of the guide groove 5 to a range in which the groove closing member 7 is mounted. However, when two groove closing members 7 are used, it is possible to freely determine the turning end on both sides.
[0018]
【The invention's effect】
As is apparent from the above description, according to the present invention, since the turning angle of the turning structure can be set freely, the versatility can be improved.
