Description

本発明は、ラック列間通路のセキュリティを向上させたラック列間通路遮蔽構造に関するものである。   The present invention relates to a rack row passage shielding structure that improves the security of the passage between rack rows.

データセンター等においては、特許文献1に示されるように、作業者が扉を開いてラック間通路に出入りしたとき、扉が開いたままで放置されることのないように、手を放すと扉が自動的に閉じる閉鎖機構を設けることが記載されている。この閉鎖機構はワイヤリール式のものである。   In a data center or the like, as shown in Patent Document 1, when an operator opens a door and enters or exits a path between racks, the door is released when the hand is released so that the door is not left open. It is described to provide a closing mechanism that closes automatically. This closing mechanism is of the wire reel type.

しかし特許文献1に示されたラック列間通路遮蔽構造では、扉に鎖錠装置が設けられていない。これはサーバルーム全体にセキュリティの確保がなされているからであるが、セキュリティをより高いレベルとするためには、ラック間通路の扉にも鎖錠装置を設けることが望まれる。ところが南京錠やシリンダ錠のような通常の鎖錠装置を取り付けただけでは、作業終了後に鎖錠忘れをすることがある。   However, in the inter-rack row passage shielding structure disclosed in Patent Document 1, the door is not provided with a locking device. This is because security is ensured throughout the server room, but it is desirable to provide a locking device at the door of the path between racks in order to achieve higher security. However, simply attaching a normal locking device such as a padlock or cylinder lock may cause you to forget the lock after the work.

特開2016−54234号公報Japanese Patent Laying-Open No. 2006-54234

従って本発明の目的は上記した従来の問題点を解決し、ラック列間通路を鎖錠忘れを発生させることなく確実に鎖錠することができるラック列間通路遮蔽構造を提供することである。   Accordingly, an object of the present invention is to solve the above-described conventional problems and provide a rack row passage shielding structure that can reliably lock the passages between rack rows without causing forgetting to lock.

上記の課題を解決するためになされた本発明は、所定間隔で対向配置されたラック列間に形成されたラック列間通路を、スライド式の2枚の扉によって遮蔽したラック列間通路遮蔽構造において、双方の扉の端部にそれぞれ鎖錠部材が設けられており、これらの鎖錠部材の少なくとも一方は、双方の扉が閉塞されたときに変位して鎖錠状態を形成するものであることを特徴とする。   In order to solve the above-described problems, the present invention provides an inter-rack row passage shielding structure in which a passage between rack rows formed between rack rows opposed to each other at a predetermined interval is shielded by two sliding doors. In the above, a locking member is provided at each end of both doors, and at least one of these locking members is displaced to form a locked state when both doors are closed. It is characterized by that.

なお、これらの鎖錠部材の少なくとも一方は扉の内側に操作部材を形成し、操作部材は扉の内側からこれらの鎖錠部材を解錠可能とすることが好ましい。   In addition, it is preferable that at least one of these locking members forms an operating member inside the door, and the operating member can unlock these locking members from the inside of the door.

また、一方の扉の内側に前記鎖錠部材の操作部材を設け、他方の扉の外側に錠を設けることが好ましい。   Moreover, it is preferable to provide the operation member of the said locking member inside one door, and to provide a lock | rock outside the other door.

またこの場合、双方の鎖錠部材が鎖錠状態で双方の扉が閉じたとき、操作部材が弾性部材の変形により変位し、再び鎖錠状態を形成することが好ましい。   In this case, when both the locking members are in the locked state and both the doors are closed, it is preferable that the operation member is displaced by the deformation of the elastic member to form the locked state again.

本発明のラック列間通路遮蔽構造によれば、双方の扉が閉塞されたときに少なくとも一方の鎖錠装置が変位して鎖錠状態を形成するので、鎖錠忘れを生ずるおそれがない。このためラック列間通路を鎖錠忘れを発生させることなく確実に鎖錠することができ、セキュリティの確保を図ることができる。   According to the inter-rack row passage shielding structure of the present invention, when both doors are closed, at least one of the locking devices is displaced to form a locked state, so there is no risk of forgetting to lock. For this reason, it is possible to reliably lock the passages between the rack rows without causing forgetting to lock, and it is possible to secure security.

以下に本発明の実施形態を説明する。
図1はデータセンター等に設置されたラック列の全体図であり、1、1は所定間隔で対向配置されたラック列、2はこれらのラック列1、1間に形成されたラック列間通路である。ラックの内部にはサーバや通信機器などの電子機器が収納されている。図面を簡略化するために、図1ではラック列1は3個のラックで形成されているが、実際にはさらに多数のラックからなる。
Embodiments of the present invention will be described below.
FIG. 1 is an overall view of rack rows installed in a data center or the like. Reference numerals 1 and 1 denote rack rows opposed to each other at a predetermined interval, and reference numeral 2 denotes a path between rack rows formed between the rack rows 1 and 1. It is. Inside the rack are stored electronic devices such as servers and communication devices. In order to simplify the drawing, the rack row 1 is formed of three racks in FIG. 1, but actually comprises a larger number of racks.

ラック列間通路2の床面には冷気吹き出し口(図示略)が形成され、ラック列間通路2に冷気を供給している。この冷気が無駄に放散されることを防止するために、ラック列間通路2の天井は天井パネル3によって覆われ、前後の出入り口にはそれぞれ、2枚の扉4が設けられている。これらの扉4は上部のレールに支持されてスライドし、外力を加えない状態では図1に示すように中央で閉じた状態となる閉鎖機構を備えたものである。具体的には、扉4の上方に位置し各々のラック列1、1に設けたレール23を傾斜させて配置し、扉4を自重で閉鎖位置までレール23上をスライドさせる構造や、各々のレール23間に設けた左右一対のワイヤリール部24によって扉4を閉鎖位置まで自動で巻き取る構造を備えたものである。ワイヤリール部24については、巻取り方向に付勢されたリールにワイヤを巻き付けた構造であり、ワイヤの先端はレール23の内部に延び、各扉4に固定されている。このため扉4を開いて手を離せば、ワイヤリール部24がワイヤを巻き取るため、各扉4は中央に引き寄せられ、自動的に閉鎖する。   A cold air outlet (not shown) is formed on the floor surface of the inter-rack row passage 2 to supply cold air to the inter-rack row passage 2. In order to prevent this cool air from being dissipated wastefully, the ceiling of the inter-rack row passage 2 is covered with a ceiling panel 3, and two doors 4 are provided at the front and rear entrances, respectively. These doors 4 are supported by upper rails and slide, and are provided with a closing mechanism that is closed at the center as shown in FIG. 1 when no external force is applied. Specifically, a structure is provided in which the rails 23 provided on the rack rows 1 and 1 located above the doors 4 are tilted and the doors 4 are slid on the rails 23 to their closed positions under their own weights. The door 4 is automatically wound up to the closed position by a pair of left and right wire reels 24 provided between the rails 23. The wire reel portion 24 has a structure in which a wire is wound around a reel biased in the winding direction, and the tip end of the wire extends inside the rail 23 and is fixed to each door 4. For this reason, when the door 4 is opened and the hand is released, the wire reel 24 takes up the wire, so that each door 4 is drawn to the center and automatically closed.

図2に示すように、双方の扉4の中央の端部にそれぞれハンドル5が設けられている。この実施形態では、ハンドル5は扉4の外側だけに設けられている。また図2に示すように、一方の扉4の外側にシリンダ錠6が取り付けられている。図3に示されるように、シリンダ錠6の裏面には第1の鎖錠部材7が取り付けられている。この第1の鎖錠部材7は常時は図3に示す位置にあるが、シリンダ錠6を操作することによって、上方に回転させることができるようになっている。第1の鎖錠部材7は金属板からなり、その先端は屈曲されて下向きの傾斜片8となっている。なお、鎖錠部材7を操作する構造は、鍵式や暗号式など特定の人間のみに解錠と施錠ができる錠であれば、シリンダ錠6以外の錠であっても良い。例えば、錠を設けたハンドルの操作により鎖錠部材7を操作するものであっても良い。   As shown in FIG. 2, a handle 5 is provided at each of the central ends of the doors 4. In this embodiment, the handle 5 is provided only outside the door 4. As shown in FIG. 2, a cylinder lock 6 is attached to the outside of one door 4. As shown in FIG. 3, a first locking member 7 is attached to the back surface of the cylinder lock 6. The first locking member 7 is always in the position shown in FIG. 3, but can be rotated upward by operating the cylinder lock 6. The first locking member 7 is made of a metal plate, and its tip is bent into a downwardly inclined piece 8. The structure for operating the locking member 7 may be a lock other than the cylinder lock 6 as long as it can be unlocked and locked only by a specific person such as a key type or an encryption type. For example, the locking member 7 may be operated by operating a handle provided with a lock.

図4は左側の扉4のカバーを外した状態を示す斜視図である。この図4に示すように、前記した第1の鎖錠部材7が取り付けられた扉4の反対側の扉には、第2の鎖錠部材9が設けられている。第2の鎖錠部材9は図4に示されるように、平板状の操作部材10の端部に立設されている。その支持構造は、次の通りである。   FIG. 4 is a perspective view showing a state in which the cover of the left door 4 is removed. As shown in FIG. 4, a second locking member 9 is provided on the door opposite to the door 4 to which the first locking member 7 is attached. As shown in FIG. 4, the second locking member 9 is erected on the end portion of the flat operation member 10. The support structure is as follows.

まず、11は金属板を略L字状に折り曲げた第1固定金具であり、扉4の端部に固定されている。また12は金属板を略コ字状に折り曲げた第2固定金具12であり、第1固定金具11の上部水平片13と第2固定金具12の下部水平片14とは、両者を垂直に貫通するボルト15により固定されている。   First, reference numeral 11 denotes a first fixing bracket obtained by bending a metal plate into a substantially L shape, and is fixed to an end portion of the door 4. Reference numeral 12 denotes a second fixing bracket 12 formed by bending a metal plate into a substantially U-shape. The upper horizontal piece 13 of the first fixing bracket 11 and the lower horizontal piece 14 of the second fixing bracket 12 penetrate both of them vertically. The bolt 15 is fixed.

図5に示すように、第2固定金具12の上部水平片17には貫通孔18が形成されており、ボルト15の先端が貫通している。また平板状の操作部材10にも貫通孔が形成されており、その内部をボルト15が貫通している。ボルト15の軸方向が第2の鎖錠部材9の変位方向となっている。   As shown in FIG. 5, a through hole 18 is formed in the upper horizontal piece 17 of the second fixing bracket 12, and the tip of the bolt 15 passes therethrough. A through hole is also formed in the flat operation member 10, and a bolt 15 passes through the inside. The axial direction of the bolt 15 is the displacement direction of the second locking member 9.

図4、図5に示すように、第1固定金具11の上部水平片13と操作部材10との間には、鎖錠部材9が鎖錠状態に自動復帰するための弾性部材であるバネ19が設けられている。バネ19は圧縮コイルバネであり、操作部材10を常に上向きに弾発している。このため外力が加えられない状態では、操作部材10及びこれに固定された第2の鎖錠部材9は、図4、図5に示す高い位置にある。しかし図6に示すように操作部材10は扉4の内側に露出しているので、内側から人手により押し下げることができる。また、上部水平片17にボルト15が貫通していることで、バネ19の上向きの弾発や人手による操作により、第2の鎖錠部材9がボルト15から脱落することを防いでいる。なお、バネ19の他にゴムやスポンジ等の弾性部材であってもよい。   As shown in FIGS. 4 and 5, between the upper horizontal piece 13 of the first fixing bracket 11 and the operation member 10, a spring 19 which is an elastic member for automatically returning the locking member 9 to the locked state. Is provided. The spring 19 is a compression coil spring and always projects the operation member 10 upward. For this reason, in a state where no external force is applied, the operation member 10 and the second locking member 9 fixed to the operation member 10 are in a high position shown in FIGS. 4 and 5. However, as shown in FIG. 6, since the operation member 10 is exposed to the inside of the door 4, it can be pushed down manually from the inside. Further, since the bolt 15 passes through the upper horizontal piece 17, the second locking member 9 is prevented from falling off from the bolt 15 due to upward bullets of the spring 19 or manual operation. In addition to the spring 19, an elastic member such as rubber or sponge may be used.

第2の鎖錠部材9には、第1の鎖錠部材7の先端の下向きの傾斜片8に接触する上向きの上側傾斜面20が形成されている。また上側傾斜面20の下側には、第1の鎖錠部材7の傾斜片8と係合する下側傾斜面21を備えた凹状係合部22が形成されている。第2の鎖錠部材9が図4、図5に示す高い位置にあるとき、上側傾斜面20は第1の鎖錠部材7の傾斜片8と同じ高さにある。また、第2の鎖錠部材9は扉4の合せ面に形成し、反対側の扉4の合せ面に形成した第1の鎖錠部材7と対向した方向に突出している。但し、第2の鎖錠部材9と第1の鎖錠部材7のいずれか一方のみが突出した構造であってもよい。   The second locking member 9 is formed with an upward upper inclined surface 20 that comes into contact with the downward inclined piece 8 at the tip of the first locking member 7. A concave engagement portion 22 having a lower inclined surface 21 that engages with the inclined piece 8 of the first locking member 7 is formed below the upper inclined surface 20. When the second locking member 9 is at the high position shown in FIGS. 4 and 5, the upper inclined surface 20 is at the same height as the inclined piece 8 of the first locking member 7. The second locking member 9 is formed on the mating surface of the door 4 and protrudes in a direction facing the first locking member 7 formed on the mating surface of the door 4 on the opposite side. However, the structure which only one of the 2nd locking member 9 and the 1st locking member 7 protruded may be sufficient.

以下に、図7から図10を参照しつつ、本発明の動作を説明する。これらの図はすべて、双方の扉4、4の当接側の端部を外側から見た図である。この実施形態では双方の扉4が閉塞されたときに、一方の鎖錠部材である第2の鎖錠部材9が変位して鎖錠状態を形成するが、本発明はこの実施形態に限定されるものではない。例えば、双方の扉4が閉塞されたときに、第1の鎖錠部材7が変位して鎖錠状態を形成してもよいし、第1の鎖錠部材7と第2の鎖錠部材9の双方が変位して鎖錠状態を形成してもよい。   The operation of the present invention will be described below with reference to FIGS. All of these drawings are views of the abutting side ends of the doors 4 and 4 as viewed from the outside. In this embodiment, when both doors 4 are closed, the second locking member 9 which is one locking member is displaced to form a locked state, but the present invention is limited to this embodiment. It is not something. For example, when both doors 4 are closed, the first locking member 7 may be displaced to form a locked state, or the first locking member 7 and the second locking member 9. Both of them may be displaced to form a locked state.

図7は双方の扉4、4が閉じた通常状態を示している。このとき右側の扉4の端部に設けられた第1の鎖錠部材7はほぼ水平位置にあり、その傾斜片8は左側の扉4に設けられた第2の鎖錠部材9の凹状係合部22内にある。より正確には、第1の鎖錠部材7の傾斜片8の下端は、第2の鎖錠部材9の凹状係合部22の下側傾斜面21の上端よりも低い位置にある。このとき、扉4を開こうとすると第1の鎖錠部材7の傾斜片8が第2の鎖錠部材9の下側傾斜面21と係合するため、扉4を開くことができない鎖錠状態が形成されている。   FIG. 7 shows a normal state in which both doors 4 and 4 are closed. At this time, the first locking member 7 provided at the end of the right door 4 is in a substantially horizontal position, and the inclined piece 8 is a concave engagement of the second locking member 9 provided in the left door 4. It is in the joint part 22. More precisely, the lower end of the inclined piece 8 of the first locking member 7 is at a position lower than the upper end of the lower inclined surface 21 of the concave engaging portion 22 of the second locking member 9. At this time, if the door 4 is opened, the inclined piece 8 of the first locking member 7 engages with the lower inclined surface 21 of the second locking member 9, so that the door 4 cannot be opened. A state is formed.

しかしこの鎖錠状態においても、図7に示されるように、傾斜片8の下端と凹状係合部22の下側傾斜面21とは、上下方向には干渉しない位置にある。このため、扉4の外側からシリンダ錠6にキイを差し込み回転させて第1の鎖錠部材7を上方に移動させるか、あるいは内側(ラック列間通路2側)から操作部材10を人手により操作して第2の鎖錠部材9を押し下げれば、第1の鎖錠部材7と第2の鎖錠部材9との係合が解除されるので、扉4を開くことが可能となる。   However, even in this locked state, as shown in FIG. 7, the lower end of the inclined piece 8 and the lower inclined surface 21 of the concave engaging portion 22 are in positions that do not interfere in the vertical direction. For this reason, a key is inserted into the cylinder lock 6 from the outside of the door 4 and rotated to move the first locking member 7 upward, or the operation member 10 is manually operated from the inside (the side between the rack rows 2). Then, if the second locking member 9 is pushed down, the engagement between the first locking member 7 and the second locking member 9 is released, so that the door 4 can be opened.

操作部材10を人手により操作して第2の鎖錠部材9を押し下げて、扉4を開いた後に操作部材10から手を放すと、図8のように第2の鎖錠部材9はバネ19の復元力によって元の高い位置に復帰する。このまま扉4を閉じて行くと、図9に示すように第1の鎖錠部材7の傾斜片8が第2の鎖錠部材9の上側傾斜面20に当たる。そのままさらに扉4を閉じて行くと、第1の鎖錠部材7は動かないので、図10に示すように第2の鎖錠部材9がバネ19を圧縮しつつ下方に変位し、さらに扉4を閉じて行くと図7の鎖錠状態に戻る。このように、扉4から手を放したまま双方の扉4が自動で閉じられると同時に、鎖錠状態が形成される。すなわち、操作部材10が形成された側の鎖錠部材がバネ19を弾性変形させて変位し、その後再び鎖錠状態が形成される。このように、人手を介することなく扉4を閉鎖し鎖錠する構造とすることにより、鎖錠忘れを防ぎセキュリティを向上することができる。また、扉4は自動で閉鎖する構造の他に、手動で閉塞される構造であっても良い。なお、手動で扉4が閉鎖されるときの第1の鎖錠部材7と第2の鎖錠部材9の作用は、上記の扉4は自動で閉鎖する構造の場合と同様である。   When the operation member 10 is manually operated to push down the second locking member 9 and release the operation member 10 after the door 4 is opened, the second locking member 9 is spring 19 as shown in FIG. It will return to its original high position due to its restoring force. When the door 4 is closed as it is, the inclined piece 8 of the first locking member 7 contacts the upper inclined surface 20 of the second locking member 9 as shown in FIG. If the door 4 is further closed as it is, the first locking member 7 does not move, so that the second locking member 9 is displaced downward while compressing the spring 19 as shown in FIG. When is closed, the locked state of FIG. 7 is restored. In this way, both doors 4 are automatically closed while releasing their hands, and at the same time a locked state is formed. That is, the locking member on the side where the operation member 10 is formed is displaced by elastically deforming the spring 19 and then the locked state is formed again. In this way, by adopting a structure in which the door 4 is closed and locked without human intervention, forgetting to lock can be prevented and security can be improved. Further, the door 4 may be manually closed in addition to the automatic closing structure. The operation of the first locking member 7 and the second locking member 9 when the door 4 is manually closed is the same as that of the structure in which the door 4 is automatically closed.

以上に説明した本発明の機能を整理すると、次の通りである。
(1)双方の扉4が閉じた状態では、第1の鎖錠部材7と第2の鎖錠部材9とによって、鎖錠状態が形成されている。
(2)外側からは、シリンダ錠6を操作して第1の鎖錠部材7を上方に回転することにより鎖錠状態を解除し、扉4を開くことができる。鍵がないと扉4を開けないので、セキュリティの確保を図ることができる。
(3)内側からは、操作部材10を操作して第2の鎖錠部材9を押し下げ、鎖錠状態を解除し、扉4を開くことができる。従ってラック列間通路2内の作業者は鍵を用いずに外に出ることができ、火事や地震などの緊急時にも脱出可能である。
(4)扉4を開いた状態で手を放すと扉4は閉鎖機構により閉じるが、これと同時に第1の鎖錠部材7と第2の鎖錠部材9とによって、自動的に鎖錠状態が形成される。よってラック列間通路2を鎖錠忘れを発生させることなく確実に鎖錠することができる。
The functions of the present invention described above are summarized as follows.
(1) In a state in which both doors 4 are closed, a locked state is formed by the first locking member 7 and the second locking member 9.
(2) From the outside, the locked state can be released and the door 4 can be opened by operating the cylinder lock 6 and rotating the first locking member 7 upward. Since the door 4 cannot be opened without a key, security can be ensured.
(3) From the inside, the operation member 10 can be operated to push down the second locking member 9 to release the locked state and open the door 4. Therefore, the worker in the inter-rack row passage 2 can go out without using a key, and can escape in an emergency such as a fire or an earthquake.
(4) When the hand is released with the door 4 opened, the door 4 is closed by the closing mechanism. At the same time, the door 4 is automatically locked by the first locking member 7 and the second locking member 9. Is formed. Therefore, the inter-rack row passage 2 can be securely locked without causing forgetting to lock.
