- Cover 126 (an example of a second lid member) is provided via a hinge 127 (an example of an elastic member).
- the cover 126 can be pushed downward with the finger 300 by the hinge 127 on the front side of the cover 126 (an example of one end side) with the finger 300 and the work is performed when the operator's finger 300 is released. It returns to the position which becomes a part of the stand 111. That is, when the operator's finger 300 moves away from the cover 126, the cover 126 returns to substantially the same plane as the cover 123. Further, in the cover 126, the opening width W between at least the rear end (an example of the other end) of 126 and the edge of the hole 125 is at least three times the thickness of the globe 400 attached to the front opening 113. It is arranged at the position that becomes the length of.
- the isolator system 100 can improve the operability for the operator.

- the bolt 128 a provided on the lower surface of the cover 123 and the bolt 128 a provided on the lower surface of the cover 126 come into contact with each other, and the cover 126 is restrained with respect to the cover 123 at a predetermined angle. Therefore, the operator can firmly apply force to the upper surface of the cover 126 with a fingertip.
- the cover 126 is restrained at a position where the acute angle with respect to the cover 123 is about 60 degrees, but it is effective that the acute angle with respect to the cover 123 is smaller than about 90 degrees.
- the acute angle with respect to the cover 123 is more effective when it is not less than 45 degrees and not more than 75 degrees.
- the bolt 128a also serves as a part for fixing the hinge 127 to the lower surfaces of the cover 123 and the cover 126.
- the first embodiment has been described as an example of the technique disclosed in the present application.
- the technology in the present disclosure is not limited to this, and can also be applied to an embodiment in which changes, replacements, additions, omissions, and the like are appropriately performed.

- the elastic member allows the operator to push the cover 126 downward with the finger 300 on one end side of the cover 126 with the rotation axis Ax, and when the operator's finger 300 is released, the cover 126 is attached to the work table 111. What is necessary is just to be able to return to the position which becomes a part. Therefore, a highly elastic member such as rubber having a restoring force or synthetic resin may be used as the elastic member.
- a highly elastic member such as rubber having a restoring force or synthetic resin may be used as the elastic member.
- the cover 126 may be attached to the cover 123 so that the center H2 of the cover 126 and the center H1 of the hole 125 do not coincide with each other.
- FIG. 12 is a schematic view showing a configuration of a cover and a hole according to another embodiment.
- FIG. 12 shows the cover 123 and the cover 126 as viewed from the upper side (+ Z) to the lower side ( ⁇ Z).

Therefore, when a sample or the like used in the work space A is placed on the cover 126B, the sample or the like rolls (slides) from the cover 126B to, for example, the cover 123 by its own weight. Therefore, the sample or the like can be prevented from staying on the cover 126B. Therefore, when the cover 126B is pushed downward by the finger 300, the sample or the like on the cover 126B can be prevented from falling into the hole 125.
- the cover 126B may be formed by punching using a mold, for example.

- the cover 126C may be formed by punching using a mold, for example. With this configuration, for example, the cover 126 ⁇ / b> C protrudes above the work table 111, and for example, it is possible to prevent an article used for the work, the globe 400, and the like from being caught.
- ⁇ Stopper> Further, in the first embodiment, it has been described that the rotation of the attachment portion 127a is restricted by the restriction portion S (FIG. 5) coming into contact with the cover 123. However, the present invention is not limited to this.
- FIGS. 15 and 16 are schematic views showing configurations of a cover and a hinge according to another embodiment.
- symbol is attached
- FIG. 15 shows a state where the rotation of the attachment portion 127a is restricted by the stopper 126D.
- FIG. 16 shows a state in which the cover 126 is moved downward based on the force applied to the cover 126 from the upper side to the lower side.
- the finger 300 and the globe 400 shown in FIG. 15 are omitted for convenience of explanation.
- the stopper 126D (FIG. 15) is fixed to the back surface ( ⁇ Z) of the cover 126.

Abstract
Description
以下、アイソレータシステムの一例として、実施の形態1でアイソレータシステム100について、図1~10を用いて説明する。
[1-1.アイソレータシステム]
アイソレータシステム100の全体構成について、図1~4を用いて説明する。図1及び図2は実施の形態1に係るアイソレータシステム100の正面図及び斜視図、図3は実施の形態1に係るインキュベータ200装着時のアイソレータシステム100の斜視図である。
アイソレータ110の構成について、図2を用いて説明する。図2に示すように、アイソレータ110は、複数の前面開口部113が設けられた前面板112、底面板、上面板、及び、左右の側面板によって区画され、作業を行う為の作業台111と仕切板117とを内部に備える。作業台111、仕切板117、上面板、及び、左右の側面板によって、作業を行う空間である箱状の作業空間Aを形成する。アイソレータ110は、外部からの菌の侵入が抑制されるように気密性を有して区画される。作業台111と底面板との間及び背面板と仕切板117との間には、作業空間A内の気体を排気するダクトが形成されている。本実施の形態のアイソレータ110は、作業台111、仕切板117、底面板、背面板、上面板、及び、左右の側面板は、清掃や消毒のしやすいステンレス鋼板で構成されている。
作業台111の構成について、図4~6を用いて説明する。図4は、実施の形態1に係る作業台111の構成を示す概略図である。
蓋部材126、137の詳細な構成について、図5、6、11を用いて説明する。図5、6は、実施の形態1に係る蓋部材126と蝶番127の構成を示す概略図である。なお、カバー137及び蝶番138の構成については、カバー126及び蝶番127の構成と同様であるので、ここでは説明を省略する。なお、図5における例えば2個の取付部127aのうちの、カバー123に取り付けられている一方が第1部分に相当し、カバー126に取り付けられている他方が第2部分に相当する。また、カバー126は、例えばレーザ加工機を用いて形成されていることとしてもよい。
作業者が作業空間Aから遠心機ユニット120に接続する動作について、図7~10を用いて説明する。図7~10は、実施の形態1に係る蓋部材と蝶番の動作を示す概略図である。ここでは、カバー123を開く動作を説明するが、カバー123を閉じる動作も、基本的に同様であるため、説明を省略する。また、観察ユニット130への接続についても同様であるため、説明を省略する。
以上のように、本実施の形態において、アイソレータシステム100(アイソレータの一例)は、外部と隔離された作業空間Aを形成し、作業空間A内に作業手を挿入するためのグローブ400が装着される複数の前面開口部113を前面に形成する略箱状のアイソレータ110(本体ケースの一例)を備える。アイソレータ110は、作業を行うための作業台111(作業板の一例)を有し、作業台111は、作業台111の下部の設けられる例えば遠心機ユニット120に作業空間Aから接続するための接続開口部115(接続開口部の一例)を形成し、かつ、作業台111の一部を構成し接続開口部115を開閉可能なカバー123(第1蓋部材の一例)を備える。カバー123は、カバー123を上方へ引き上げて開くために作業者が指を引っ掛ける孔部125(孔部の一例)を形成し、かつ、作業台111の一部を構成し孔部125を開閉可能なカバー126(第2蓋部材の一例)を蝶番127(弾性部材の一例)を介して備えている。カバー126は、蝶番127によって、カバー126の前側(一端側の一例)を回動軸Axに作業者が指300で下方へ押し込むことが可能であり、かつ、作業者の指300が離れると作業台111の一部となる位置まで戻る。つまり、作業者の指300がカバー126から離れると、カバー126は、カバー123と略同一平面上に戻ることになる。さらに、カバー126は、少なくとも126の後ろ側(他端側の一例)の端部と孔部125の縁部との開口幅Wが前面開口部113に装着されるグローブ400の厚みの3倍以上の長さになる位置に配置されている。
以上のように、本出願において開示する技術の例示として、実施の形態1を説明した。しかしながら、本開示における技術は、これに限定されず、適宜、変更、置き換え、付加、省略などを行った実施の形態にも適用可能である。また、上記実施の形態1説明した各構成要素を組み合わせて、新たな実施の形態とすることも可能である。
<カバー及び孔部の中心>
また、カバー126及び孔部125(実施の形態1)が、図5に示されるように略円形状を呈しており、双方の中心が略一致するように設けられていることに限られない。例えば、図12に示されているように、カバー126の中心H2と孔部125の中心H1とが一致しないように、カバー126がカバー123に取り付けられることとしてもよい。
<カバーの形状>
また、カバー126(実施の形態1)が、図6に示されるように平板形状を呈していることに限られない。例えば、カバー126に対応するカバー126B(図13)、カバー126C(図14)のように湾曲した形状を呈していることとしてもよい。図13、14は、他の実施の形態に係るカバーと蝶番の構成を示す概略図である。なお、図13、14における図6に示されている構成と同様な構成には、同様な符号を付し、その説明については省略する。
<ストッパー>
また、実施の形態1では、規制部S(図5)がカバー123に当接することにより取付部127aの回動が規制されることについて説明したが、これに限定されるものではない。例えば、カバー126に対して、取付部127aの回動を規制するストッパー126D(図15、16)が設けられることとしてもよい。図15、16は、他の実施の形態に係るカバーと蝶番の構成を示す概略図である。なお、図15、16における図6に示されている構成と同様な構成には、同様な符号を付し、その説明については省略する。図15は、ストッパー126Dによって取付部127aの回動が規制されている状態を示している。図16は、カバー126に上方から下方に向かって付与された力に基づいてカバー126が下方へ移動されている状態を示している。尚、図16においては、図15に示されている指300及びグローブ400は、説明の便宜上省略されている。
