Description

本発明は、各種電気機器を収納するキャビネットラックのフレーム構造に関する。   The present invention relates to a frame structure of a cabinet rack that houses various electrical devices.

従来、底枠に４本のポストを立て、各ポストの上端に天枠を取り付け、底枠とポストと天枠とでフレームを構成し、フレームの内側に電気機器の収納室を形成したキャビネットラックが知られている。例えば、特許文献１には、収納室の左右両側面を覆うパネルをフレームに着脱可能に取り付け、配線作業を容易にする技術が記載されている。   Conventionally, a cabinet rack in which four posts are set up on the bottom frame, a top frame is attached to the top of each post, a frame is composed of the bottom frame, posts, and top frame, and a storage room for electrical equipment is formed inside the frame. It has been known. For example, Patent Document 1 describes a technique for facilitating wiring work by detachably attaching a panel that covers both left and right side surfaces of a storage room to a frame.

また、従来、ポストの内側に電気機器のケーブル類を配線する技術が知られている。例えば、特許文献２には、図５に示すように、ポスト５１を金属板で内側が開いた形状に折り曲げ形成し、ポスト５１の内面に別の金属板５２を接合し、この金属板５２の内側にケーブルＣを通す配線ダクト５３を形成したフレーム構造が提案されている。   Conventionally, a technique for wiring cables of electrical equipment inside a post is known. For example, in Patent Document 2, as shown in FIG. 5, a post 51 is formed by bending a metal plate into an open shape, and another metal plate 52 is joined to the inner surface of the post 51. There has been proposed a frame structure in which a wiring duct 53 through which a cable C is passed is formed.

特開２００２−１８５１７０号公報JP 2002-185170 A 特開２０１２−０８４６０５号公報JP2012-084605A

従来のフレーム構造によれば、ポスト５１を内側が開くように形成しているので、ケーブルＣを配線ダクト５３に容易に出し入れできる。しかし、一部が開いたポスト５１は、全周が閉じた中空管と比較して剛性が低下する。このため、従来は、配線ダクト５３をポスト５１と別の金属板５２で形成し、この金属板５２でポスト５１を補強し、ラックの耐震性能を高める必要があり、フレーム構造の製作コストが嵩むという問題点があった。   According to the conventional frame structure, since the post 51 is formed so that the inner side is opened, the cable C can be easily put in and out of the wiring duct 53. However, the post 51, which is partially open, is less rigid than the hollow tube whose entire circumference is closed. For this reason, conventionally, it is necessary to form the wiring duct 53 with the metal plate 52 different from the post 51, and to reinforce the post 51 with this metal plate 52 to improve the seismic performance of the rack, increasing the manufacturing cost of the frame structure. There was a problem.

そこで、本発明の目的は、簡単かつ安価な構成で、キャビネットラックの耐震性能を高めることができるフレーム構造を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide a frame structure that can enhance the seismic performance of a cabinet rack with a simple and inexpensive configuration.

以下、本発明の実施形態を図面に基づいて説明する。図１に示すように、この実施形態のキャビネットラック１は縦長箱形のフレーム２を備えている。フレーム２は、天枠３、底枠４、ポスト５、マウントアングル６およびマウントレール７から構成されている。フレーム２の内側には、電気機器を収納する収納室８が形成されている。フレーム２の前面は扉（図示略）で覆われ、上面、下面、側面、背面がそれぞれパネル（図示略）で覆われている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the cabinet rack 1 of this embodiment includes a vertically long box-shaped frame 2. The frame 2 includes a top frame 3, a bottom frame 4, a post 5, a mount angle 6 and a mount rail 7. A storage chamber 8 for storing electrical equipment is formed inside the frame 2. The front surface of the frame 2 is covered with a door (not shown), and the upper surface, the lower surface, the side surface, and the back surface are covered with panels (not shown).

ポスト５およびマウントアングル６は、それぞれ４本が天枠３と底枠４の間に立設されている。ポスト５は底枠４の４つのコーナ部に立設され、各ポスト５の上端に天枠３が取り付けられている。マウントアングル６は前後のポスト５の間に立設され、マウントレール７が前後のマウントアングル６に高さ調節可能に架設されている。   Four posts 5 and four mount angles 6 are provided between the top frame 3 and the bottom frame 4, respectively. The posts 5 are erected at the four corners of the bottom frame 4, and the top frame 3 is attached to the upper end of each post 5. The mount angle 6 is erected between the front and rear posts 5, and a mount rail 7 is installed on the front and rear mount angles 6 so that the height can be adjusted.

図２に示すように、ポスト５は一枚の金属板を折り曲げて形成されている。ポスト５には、電気機器のケーブルを通すためのダクト部１０が設けられるとともに、補強部１１がダクト部１０と連続するように一体形成されている。ダクト部１０は、金属板をポスト５の長手方向に延びる４本の折曲線１２で一方向へ直角に巻き回して形成されている。   As shown in FIG. 2, the post 5 is formed by bending a single metal plate. The post 5 is provided with a duct portion 10 for passing a cable of an electric device, and a reinforcing portion 11 is integrally formed so as to be continuous with the duct portion 10. The duct portion 10 is formed by winding a metal plate perpendicularly in one direction with four folding lines 12 extending in the longitudinal direction of the post 5.

補強部１１は、金属板を３本の折曲線１３でダクト部１０と反対方向へ直角に折り曲げて形成されている。そして、ダクト部１０の周壁に、縦長の配線用スリット１４が収納室８に向かって開放するように形成され、ポスト５の外面が平滑に形成されている。なお、マウントアングル６は、一枚の金属板を断面が略Ｓ字形となるように折り曲げられている。   The reinforcing portion 11 is formed by bending a metal plate at three angles in the direction opposite to the duct portion 10 along three folding lines 13. And the longitudinally long slit 14 for wiring is formed in the surrounding wall of the duct part 10 so that it may open toward the storage chamber 8, and the outer surface of the post | mailbox 5 is formed smoothly. In addition, the mount angle 6 is bent so that one metal plate may have a substantially S-shaped cross section.

図１、図３に示すように、底枠４は４本のレール１５で構成されている。各レール１５は金属板を折り曲げて形成され、両端が底枠４のコーナ部で隣接するレール１５に溶接により結合されている。底枠４の各コーナ部には、ダクト部１０の下端縁１６を差し込む複数の係止溝１７が形成され、係止溝１７によってポスト５の下端が底枠４に係止されている。   As shown in FIGS. 1 and 3, the bottom frame 4 includes four rails 15. Each rail 15 is formed by bending a metal plate, and both ends thereof are joined to the adjacent rail 15 at the corner portion of the bottom frame 4 by welding. In each corner portion of the bottom frame 4, a plurality of locking grooves 17 into which the lower end edge 16 of the duct portion 10 is inserted are formed, and the lower ends of the posts 5 are locked to the bottom frame 4 by the locking grooves 17.

上記構成のフレーム構造によれば、一枚の金属板を一方向に巻き回してダクト部１０を形成したので、簡単かつ安価な構成でキャビネットラック１の耐震性能を高めることができる。また、ダクト部１０の周壁に内向きの配線用スリット１４を設けたので、図４に示すように、コードＣを収納部８からダクト部１０に収めたり、ダクト部１０から収納部８に取り出したりすることも容易にできる。さらに、ダクト部１０のエッジがポスト５の内側に巻き込まれているため、ラック１から扉を取り外したときに、フレーム２の前面開口部にエッジや凹凸部が露出しなくなる。したがって、扉を外した状態でも、キャビネットラック１を安全に使用できるとともに、美観を優れたものとすることができる。   According to the frame structure having the above configuration, the duct portion 10 is formed by winding a single metal plate in one direction, so that the seismic performance of the cabinet rack 1 can be enhanced with a simple and inexpensive configuration. Further, since the inward wiring slits 14 are provided on the peripheral wall of the duct portion 10, as shown in FIG. 4, the cord C is stored in the duct portion 10 from the storage portion 8 or taken out from the duct portion 10 to the storage portion 8. Can also be easily done. Further, since the edge of the duct portion 10 is wound inside the post 5, when the door is removed from the rack 1, the edge and the uneven portion are not exposed at the front opening of the frame 2. Therefore, even when the door is removed, the cabinet rack 1 can be used safely and the aesthetic appearance can be improved.

なお、本発明は上記実施形態に限定されるものではなく、例えば、底枠４と同様に、天枠３の各コーナ部にポスト５の上端縁を差し込む係止溝を形成したり、マウントアングル６の断面形状を変更したりするなど、本発明の趣旨を逸脱しない範囲で、ラック各部の構成や形状を適宜に変更して実施することも可能である。   The present invention is not limited to the above-described embodiment. For example, similarly to the bottom frame 4, a locking groove for inserting the upper end edge of the post 5 is formed in each corner portion of the top frame 3, or the mount angle For example, the configuration and shape of each part of the rack can be changed as appropriate without departing from the spirit of the present invention, such as changing the cross-sectional shape of FIG.
