Description

【０００１】
【発明の属する技術分野】
この発明は、監視用のＣＲＴ等の重量物を卓上に固定する技術分野に属する。
【０００２】
【従来の技術】
従来監視用のＣＲＴ等を卓上に設置する場合は図５(Ａ)に示すように、ＣＲＴ５１を卓５２上に載置し、ＣＲＴ５１の脚台５１aを固定する取付金具５３をネジ手段５４で卓表面に固定する方法が採用されていた。この従来の固定方法（以下、従来構造１という）は、一様固定はできるものの、卓上が煩雑で美観を損ねるという問題があり、また、突出部があるために作業者に怪我を負わせる危険性もあり課題であった。更に、卓上を他の目的に利用できないので、省スペース化が図れないと課題もあった。
【０００３】
また、従来の別の固定手段として、図５（Ｂ）に示すように、両端に接着片５６を有するベロクロテープ５７で固定する方法も行われていた。この固定方法（以下、従来構造２という）は、固定作業が簡単であるが、固定が不完全であり、災害時にはＣＲＴ５１が転倒する恐れもあり危険であった。更に、美観を損ねるという点でも問題であった。
【０００４】
更に、別の従来装置として、公開特許公報（特開平９−１１４５４５）に開示されているものがある。この装置（以下、従来構造３という）は図６に、また、固定方法を図７に示す。この従来装置は、図６に示すように、机６２の天板６３を切り欠いた長方形の凹部をなし、この凹部にＣＲＴ６１のベース部６５を設置するための装置設置面６３ａと、凹部の対向する２つの壁面６９に設けられた装置設置面６３ａに平行な案内溝（図示省略）と、装置設置面６３ａ上に配置されかつ案内溝に案内されて移動し、ベース部６５の側部を両側から挟持する一対の固定部材６４とから構成され、固定部材６４の両端部には、ロック機能を有するロックボタン６７と、一端がロックボタン６７の動作に連動する押さえピン６８（図示省略）とからなり、固定部材６４を装置設置面６３ａ任意の位置に制止し固定する係止手段をそれぞれ内蔵している。
【０００５】
この装置の固定方法は、図７（ａ）〜（ｃ）に示す手順で行われる。（ａ）先ず、机６２の天板６３上の装置設置面６３ａに設けられている一対の固定部材６４をＣＲＴ６１のベース部６５が入る程度にまで前後方向に広げておき、ＣＲＴ６１を装置設置面６３ａ上の任意の位置に設置する。（ｂ）続いて、固定部材６４をベース部６５の前後に移動させ、がたつきのないように押圧しながら挟持する。（ｃ）ここで、ロックボタン６７を押すことにより、押さえピンの他端が案内溝の壁面に当接し係合する。これによりＣＲＴ６１はそのベース部６５がゴム６６を介して固定部材６４に確実に挟持される。
【０００６】
この従来装置においては、ＣＲＴを固定した状態では固定部材６４と天板６３の凹部壁面６９との間に細い溝が生じ、また、ＣＲＴの側面両側にも細い溝が生じる。従って、この溝に埃やごみ等が溜まり易く、掃除が困難であるという問題がある。更に、全体の見映も煩雑な感じを与えるという欠点もある。また、災害時の振動に対してベース部６５を挟持しただけでは固定の強度が不十分であるだけでなく、掃除の際或いは無意識の間に誤ってロックボタンが解除される可能性もあり、更に長期間の間にゴムが劣化して挟持力を失う恐れもある。けだし、災害は何時起きるか予測しがたいものであるから長期間にわたって安全を維持する必要があるからである。
【０００７】
【発明が解決しようとする課題】
上記に説明したように、従来構造１〜従来構造３においては、美観を損ねるという課題があるだけでなく、安全性も十分に確保されず、卓上を広く利用できないという課題もあった。
本発明は、上記課題を解決し、美観的にも十分に優れ、かつ災害時にも安全で、卓上も広く利用可能な固定構造を提供することを課題としている。
【０００８】

【００１４】
図４は固定部材１８の構成を示す。図４（Ａ）は全体斜視図で、図４(Ｂ)はＹ−Ｙから見た断面図を示す。図４に示すように、固定部材１８は金属製アングルを矩形状のリングで構成するのが望ましいが、４個のアングル部材で構成し、リングになっていなくても良い。また、平板カバー１５、固定部材１８、及び収納部１４の底板１４aにはネジ１７を貫通させ、固定するための複数個の小穴１９が設けられている。ネジ１７は底板１４aの下側からナット２０、スプリングワッシャ２１で固定される。また、ネジ１７の頭部１７aは皿状になっており、卓上板１１の表面と一致するように構成されている。なお、ネジ１７は固定部材１８の下側にナットを固設しておいて、そのナットで固定するように構成してもよい。
【００１５】
以上に本実施形態についての説明から判断されるように、本実施形態のＣＲＴ固定構造は美観に優れているだけでなく、災害時にも転倒をすることがなく安全である。さらに、卓上表面のスペースが広く他の作業（例えば、作業日誌の作成等）も行えて、省スペース化が図られている。
【００１６】
以上、この発明の実施形態、実施例を図面により詳述してきたが、具体的な構成はこの実施例に限られるものではなく、この発明の要旨を逸脱しない範囲の設計の変更等があってもこの発明に含まれる。
【００１７】

BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of fixing a heavy object such as a CRT for monitoring on a table.
[0002]
[Prior art]
When a conventional monitoring CRT or the like is installed on a table, as shown in FIG. 5 (A), the CRT 51 is placed on the table 52, and the mounting bracket 53 for fixing the leg base 51a of the CRT 51 is fixed by the screw means 54. A method of fixing to the surface was adopted. Although this conventional fixing method (hereinafter referred to as the conventional structure 1) can be fixed uniformly, there is a problem that the tabletop is cumbersome and impairs aesthetics, and there is a risk of injury to the operator due to the protrusions. There was a problem and it was a problem. Furthermore, since the desktop cannot be used for other purposes, there has been a problem if space cannot be saved.
[0003]
Further, as another conventional fixing means, as shown in FIG. 5B, a method of fixing with Velcro tape 57 having adhesive pieces 56 at both ends has been performed. Although this fixing method (hereinafter referred to as the conventional structure 2) is easy to fix, the fixing is incomplete and there is a risk that the CRT 51 may fall down during a disaster. Furthermore, it was also a problem in that it detracted from aesthetics.
[0004]
Further, another conventional apparatus is disclosed in an open patent publication (Japanese Patent Laid-Open No. 9-114545). This device (hereinafter referred to as conventional structure 3) is shown in FIG. 6, and the fixing method is shown in FIG. As shown in FIG. 6, this conventional device has a rectangular recess formed by cutting out the top plate 63 of the desk 62, and the device installation surface 63a for installing the base portion 65 of the CRT 61 in this recess is opposed to the recess. A guide groove (not shown) parallel to the device installation surface 63a provided on the two wall surfaces 69, and arranged on the device installation surface 63a and guided and moved by the guide groove. The fixing member 64 includes a lock button 67 having a lock function and a pressing pin 68 (not shown) whose one end is interlocked with the operation of the lock button 67. Thus, locking means for locking and fixing the fixing member 64 at an arbitrary position of the apparatus installation surface 63a is incorporated.
[0005]
The fixing method of this apparatus is performed in the procedure shown to Fig.7 (a)-(c). (A) First, a pair of fixing members 64 provided on the device installation surface 63a on the top plate 63 of the desk 62 are spread in the front-rear direction to the extent that the base portion 65 of the CRT 61 is inserted, and the CRT 61 is installed on the device installation surface. It is installed at an arbitrary position on 63a. (B) Subsequently, the fixing member 64 is moved back and forth of the base portion 65 and is clamped while being pressed so as not to be rattled. (C) Here, by pressing the lock button 67, the other end of the pressing pin comes into contact with and engages with the wall surface of the guide groove. As a result, the base portion 65 of the CRT 61 is securely held by the fixing member 64 via the rubber 66.
[0006]
In this conventional apparatus, a thin groove is formed between the fixing member 64 and the concave wall surface 69 of the top plate 63 in a state where the CRT is fixed, and a thin groove is also formed on both side surfaces of the CRT. Therefore, there is a problem that dust, dust, and the like are easily collected in the groove and cleaning is difficult. Furthermore, there is also a drawback that the overall appearance gives a complicated feeling. Further, not only is the fixing strength insufficient when the base portion 65 is sandwiched against the vibration at the time of a disaster, but the lock button may be accidentally released during cleaning or unconsciously, Furthermore, there is a risk that the rubber will deteriorate over a long period of time and lose the clamping force. However, it is difficult to predict when a disaster will occur, so it is necessary to maintain safety over a long period of time.
[0007]
