【0001】
【発明の属する技術分野】
本発明は、主にキャビネット(筐体)からラック等の引出し部材を引き出すために用いられるスライドレールに関し、さらには、引き出した状態でラックの後面が上方に向くように揺動させることができるスライドレールに関する。
【0002】
【従来の技術】
複数のプリント回路基板等を有する電子機器をキャビネットに収容する場合、製作および保守点検を容易に行うことができるように、プリント回路基板をラックに収容するとともに、ラックとキャビネット本体との間に設けたスライドレールによってラックをキャビネット本体に対して引出し・格納自在な構成とすることが多い。
【0003】
近時においては、電子機器の構成が複雑化しているにも拘らず、キャビネットを小型化する要求が多いため、ラック内に多数のプリント回路基板を設けるとともに、ラックの前後方向(引き出し方向)いっぱいの寸法でプリント回路基板を設けている。
【0004】
このため、ラックの後面側からの保守・点検を容易に行うことができるように、キャビネット本体からラックを引き出した後に、キャビネットを下方に90°回転させる(後面を上方に向かせる)ことができるように、屈折自在に構成されたスライドレールが従来から知られている。このように構成されたスライドレールは、ラックの左右側面に取り付けられ、スライドレールの前端部に設けられたレバーを操作することにより、スライドレールを直線状に伸ばした状態での保持および屈折が可能に構成されている。
【0005】
【発明が解決しようとする課題】
しかしながら、上記のように構成されたスライドレールにおいては、ラックをキャビネットから引き出す際には両手を使うことができても、レバーを操作するためには片手でラックを支持し、片手でレバーの操作を行わなければならない。このため、作業者が一人でラックの回転作動を行わせることが困難であるという問題があり、特にラックが重い場合には作業者の労力の増大に繋がるという問題があった。
【0006】
本発明はこのような問題に鑑みてなされたものであり、キャビネットから水平に引き出したラックを、簡単な操作で上下方向に回転させることができるスライドレールを提供することを目的としている。
【0007】
【課題を解決するための手段】
上記の目的を達成するため、本発明に係るスライドレールは、筐体に結合される筐体側スライドレール部材と、この筐体側スライドレール部材に対して相対的にスライド移動可能に組み付けられるとともに、引出し部材に結合される引出し側スライドレール部材とから構成されている。引出し側スライドレール部材は、筐体側スライドレール部材にスライド自在に組み付けられる基端部材と、この基端部材よりスライド方向外側に位置して引出し部材と結合されるとともに、外側にスライド移動された状態で筐体側スライドレール部材から外方に突出して位置する先端部材とからなる。そして、基端部材と先端部材とは連結部材によって直線状に並んだ状態でロック保持可能に連結される。
【0008】
連結部材は、基端部材に対して先端部材を上下に揺動可能にするとともに、基端部材に対して先端部材の揺動軸をスライド方向に移動可能にして基端部材と先端部材とを連結している。そして、この連結部材は、基端部材に対して揺動軸をスライド方向内側に移動させて位置させたときに、基端部材と先端部材とを直線状に並んで一体に筐体側スライドレール部材に対してスライド移動自在であるとともに、直線状に並んだ位置から基端部材に対して先端部材の下方への揺動を規制し上方への揺動のみを許容して基端部材と先端部材とをロック保持する状態と、基端部材に対して先端部材を上方に揺動させた後、基端部材に対して揺動軸をスライド方向外側に移動させて位置させたときに、基端部材に対して先端部材の下方への揺動の上下方向の揺動を許容して基端部材と先端部材のロック保持を解除する状態とを有している。連結部材が基端部材と先端部材とをロック保持した状態で引出し部材を筐体から外側にスライド移動させた後、引出し部材を上方に揺動させることにより先端部材を上方に揺動させるとともにスライド方向外側に揺動軸を移動させて連結部材のロック保持を解除した状態とし、引出し部材を下方に揺動させて基端部材に対して先端部材が略垂直方向下方に延びて引出し部材の後面が上方を向く。
【0009】
このように構成されたスライドレールによれば、連結部材によって基端部材と先端部材とが直線状に並んで上方への揺動のみが許容される状態で保持されるため、引出し部材を手前に引っ張れば筐体側スライドレール部材に対して引出し側スライドレール部材をスライド移動させることができ、引出し部材を筐体から水平に引き出しすことができる。
【0010】
そして、先端部材が筐体側スライドレール部材の外方に位置するまで引出し側スライドレール部材をスライド移動させた状態で、許容されている先端部材の上方への揺動を行うと、揺動軸を移動させて先端部材をスライド方向外側への移動を行わせることもできるようになるため、先端部材を上方に揺動させるとともにスライド方向外側に移動させればロック保持が解除されて先端部材の基端部材に対する上下方向の揺動も許容される。したがって、先端部材に結合された引出し部材を支えている手を離せば、引出し部材の自重によって先端部材が下方に回動し、引出し部材の後面を上方に向けることができる。
【0011】
なお、上記の連結部材は、基端部材および先端部材の一方にスライド方向に延びて形成された長穴を有するとともに、基端部材および先端部材の他方にはこの長穴に遊嵌して基端部材に対して先端部材をスライド方向の移動および上下方向の揺動を可能に連結させる連結突起を有した構成とすることが好ましい。
【0012】
さらに、基端部材および先端部材の一方にストッパ突起を形成し、基端部材および先端部材の他方にストッパ突起受容溝を形成した構成とすることが好ましく、ストッパ突起受容溝は、基端部材と先端部材とを直線状に並んだ状態でストッパ突起と当接して先端部材の基端部材に対するスライド方向への移動および下方への揺動を阻止し、先端部材を上方に揺動させてからスライド方向外側に移動させてストッパ突起の受容保持を開放して先端部材の基端部材に対する上下方向の揺動を許容させる。
【0013】
このような構成とすることにより、基端部材と先端部材とを直線状に並べた状態においては、ストッパ突起がストッパ突起受容溝に受容されるため、先端部材は基端部材に対して直線状に並んだまま保持される。また、このように直線状に並んで保持された状態においては、先端部材の前方への移動が阻止されており、先端部材を引き出せば基端部材も一体となって筐体側スライドレールから引き出されるため、筐体から引出し部材を水平に引き出すことができる。
【0014】
上記のように先端部材と基端部材とが直線状に保持された状態においても、基端部材に対する先端部材の上方への揺動は可能であり、揺動させた状態においては、先端部材は基端部材に対して長穴の長さ分だけスライド移動自在となる。このため、引出し部材を上方に持ち上げてストッパ突起をストッパ突起受容溝から外し、この状態のまま引出し部材を手前に引き出せば、引出し部材を水平状態に戻してもストッパ突起がストッパ受容溝に再び受容されることがないため、引出し部材の下方への揺動を行うことができる。
【0015】
【発明の実施の形態】
以下、本発明の好ましい実施の形態について図面を参照しながら説明する。まず、本発明に係るスライドレール10が設けられたキャビネット20について、図1を参照しながら説明する。キャビネット20は、キャビネット本体(筐体)21と、このキャビネット本体21に対して前後方向に引出し・収納自在に構成された複数のラック22〜25とからなる。
【0016】
各ラック22〜25は、両側面に取り付けられたスライドレール10,10′を介してキャビネット20に取り付けられている。なお、図1においては、説明の便宜上、上から2段目のラック23を取り付けるスライドレール10,10′のみを表しており、スライドレール10′はスライドレール10の左右勝手違いに構成されたものである。ここで、図2から図4を加えて、ラック22〜25の左側面に取り付けられるスライドレール10について説明する。
【0017】
スライドレール10は、引出し側レール部材(引出し側スライドレール部材)11と、第一筐体側レール部材12と、第二筐体側レール部材13とから構成されている。引出し側レール部材11は、ラック23の左側面23aに取り付けられ、第一筐体側レール部材12に対してテレスコピックに(入れ子式に)伸縮自在に構成されている。第一筐体側レール部材12は、キャビネット本体21に取り付けられる第二筐体側レール部材13に対してテレスコピックに伸縮自在に構成されている。これにより、引出し側レール部材11は、第二筐体側レール部材13に対して伸縮自在に構成されることとなる。なお、このスライドレール10においては、第一筐体側レール部材12および第二筐体側レール部材13が、請求の範囲に記載の筐体側スライドレール部材を構成している。
【0018】
引出し側レール部材11は、ラック23が結合される先端部材11aと、第一筐体側レール部材12に対して伸長させた状態で第一筐体側レール部材12に支持される基端部材11bとから構成されている。先端部材11aと基端部材11bとは、連結部材14によって繋がれており、この連結部材14は、先端部材11aに取り付けられる先端側連結部材14aと、基端部材11bに取り付けられる基端側連結部材14bとからなる。
【0019】
引出し側レール部材11は、断面形状が略コの字形に形成されており、連結部材14は、この引出し側レール部材11の内空間内に配設されている。先端側連結部材14aは、矩形板状に形成された先端側連結部材本体14cと、この先端側連結部材本体14cの外側に向かって突出して配設された連結突起14dとストッパ突起14eとから構成されている。先端側連結部材本体14cは、先端部11aから後方に突出するように伸びて取り付けられ、連結突起14dは、この先端部側連結部材本体14cの後方に配設されている。また、ストッパ突起14eは、連結突起14dよりも前方に配設されている。
【0020】
基端側連結部材14bは、先端側連結部本体14cと同様に板状に形成されており、前記連結突起14dが遊嵌可能な長穴14fが形成されている。また、基端側連結部材14bの先端部には、ストッパ突起14eが受容可能な受容部14gが形成されている。受容部14gは、J字状に形成されており、ストッパ突起14eの前方下側を支持することができるようになっている。
【0021】
このように構成された先端側連結部材14aと基端側連結部材14bとは、連結突起14dを長穴14f内に挿入した状態で連結される。この連結は、先端側連結部材14aが移動可能な状態で、基端部11bと基端側連結部材14bとで先端側連結部材14a挟持するようにしてなされる。
【0022】
長穴14fは、基端側連結部材14bにおいて前後方向に伸びて形成されており、後端部14hが若干上方に上がるように形成されるとともに、前端部14iが若干下方に下がるように形成されている。そして、受容部14gにストッパ突起14eが受容された状態においては、連結突起14dが後端部14hに位置するようになっている。
【0023】
このような状態においては、連結突起14dは後端部14hにおいて若干の引っ掛かりを有するとともに、ストッパ突起14eは受容部14gにおいて上方に伸びる受容溝14jに受容されて引っかかっているため、先端部11a(ラック23)を前方に引き出せば、基端部11bも筐体側レール部材12に対して引き出される。なお、連結突起14dが後端部14hで引っ掛かるとともにストッパ突起14eが受容溝14jに受容されている状態においては、先端部11aと基端部11bとは直線状に並んでロック保持される。
【0024】
このように構成されたキャビネット20においては、図2に示すように、ラック23を前方に引くと、連結部材14によって一体に繋がった引出し側レール部材11が、筐体側レール部材12に対して伸長するとともに、第一筐体側レール部材12が第二筐体側レール部材13に対して伸長する。ここで、各レール部材11〜13の伸長量は、各レール部材を全伸させた状態におけるキャビネット本体21の前面21aからラック23の裏面23bまでの距離L1が、連結突起14dの中心からラック23の下面23cまでの距離L2よりも長くなるように設定され、且つ、連結部材14が第一筐体側レール部材12から完全に露出するように設定される。
【0025】
これにより、ラック23を水平に引くことにより、上面23dおよび下面23cをキャビネット本体21から完全に露出させることができるため、ラック23内に配設されたプリント回路基板(図示せず)の上面側および下面側からの保守点検を容易に行うことができる。
【0026】
次に、ラック23の後面側からの保守点検を行うために、ラック23を90°回転させて後面23bを上方に向ける場合の操作について説明する。ラック23を回転させる場合には、図2に示すようにラック23を完全に引き出した状態から、図3に示すように、ラック23を上方に持ち上げながら若干手前に引っ張り、受容部14gをストッパ突起14eが乗り越えるようにする。
【0027】
このようにストッパ突起14eが受容部14gを乗り越えた状態においては、先端側連結部材14aは基端側連結部材14bに対して、長穴14f内に位置する連結突起14dのみによって枢支されることとなる。従って、先端部11aが基端部11bに対して上下方向に揺動自在に構成されることとなり、キャビネット本体21に対してラック23が上下方向に揺動自在に保持される。
【0028】
これにより、ラック23を支持している手の力を緩めれば、図4に示すように、ラック23は後面23bを上に向けた状態となるまで90°回動する。このように後面23bを上に向けることにより、後面23bの外方が開放された状態となるため、後面23bに設けられたパネルをラック23から取り外せば、ラック23内に配設されたプリント回路基板等の保守点検を容易に行うことができる。
【0029】
なお、本発明のスライドレールにおいては、連結部材114を図5に示すような構成としてもよい。この連結部材114は、前記の連結部材14と同様に先端側連結部材114aと基端側連結部材114bとから構成されている。ここで、先端側連結部材114aは、前記の先端側連結部材14aと同様に二本の突起114d,114eを有して同様に形成されているため、ここでの詳細な説明は省略する。
【0030】
図5(A)に示すように、基端側連結部材114bも長穴114fを有するとともに受容部114gを有して構成されているが、受容部114gにおいては、前記の受容部14gよりも先端部114kが後方に戻るような形状で形成されている。従って、先端側連結部材114aを上方に揺動させるためには、(B)に示すように、先端側連結部材114aを後方に移動させた後に上方に揺動させる。その後(C)に示すように、連結突起114dを長穴の前端部まで移動させれば、受容部114gをかわして先端側連結部材114aを下方に揺動させることができる。
【0031】
このように構成された連結部材14によれば、先端側連結部材114aと基端側連結部材114bとを直線状に伸ばした状態での保持をより確実に行うことができる。なお、この連結部材14を用いた場合には、引出し部材を下方に揺動させる場合に一度後方に押す必要があるため、このとき引出し側レール部材および筐体側レール部材が縮小しないように、各レール部材の縮小方向の作動時に若干の抵抗を付与させるようにしている。
【0032】
さらに、図6(A),(B),(C)に示すように、基端側連結部材214bの前方に長穴214fを形成するとともにその後方にはストッパ突起214eを設けた構成とし、先端側連結部材214aの後端部に受容部214gを設けるとともにこの受容部214gの前方に連結突起214dを設けて、連結部材214を構成してもよい。このような構成としても、前記各連結部材14,114と同様に先端側連結部材214aに取り付けられた引出し部材を上方に持ち上げた後に手前に引き出せば、引出し部材の上下方向の揺動が自在となる。
【0033】
【発明の効果】
以上のように、本発明に係るスライドレールにおいては、筐体側に結合される基端部材と、引出し部材側に連結される先端部材とは、連結部材によって直線状にロック保持されるため、引出し部材を水平に引くことにより筐体から引出し部材を引出すことができる。そして、引出し部材を引出した状態から、そのまま手を離したり持ち変えたりすることなく、引出し部材を上方に持ち上げながら手前に引けば、連結部材によるロック保持が解除されて基端部材に対して先端部材が上下方向に回動自在に枢支されることとなる。このため、引出し部材を支持している手を離せば引出し部材の後面が上方に向くように回動させることができる。
【0034】
ここで、連結部材は、基端部材か先端部材の一方に長穴を形成し、他方にはこの長穴に遊嵌する連結突起を設けるとともに、基端部材か先端部材の一方にストッパ突起を形成し、他方にはこのストッパ突起を受容するストッパ突起受容溝を形成することが好ましい。そして、このストッパ突起とストッパ突起受容溝とによって、基端部材と先端部材とを直線状に並んだ状態で先端部材の基端部材に対するスライド方向外側への移動および下方への揺動を阻止し、先端部材を上方に揺動させてからスライド方向外側に移動させてストッパ突起の受容を開放して上下方向の揺動を許容するようにすれば、簡単な構成で、各スライドレール部材から突出することがない連結部材を得ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slide rail mainly used for pulling out a drawer such as a rack from a cabinet (housing), and furthermore, a slide which can be swung so that the rear surface of the rack faces upward in a drawn state. About rails.
[0002]
[Prior art]
When electronic equipment having a plurality of printed circuit boards is housed in a cabinet, the printed circuit boards are housed in a rack and provided between the rack and the cabinet body so that manufacture and maintenance and inspection can be easily performed. In many cases, the rack can be drawn out and stored in the cabinet body by the slide rail.
[0003]
Recently, in spite of the complexity of electronic devices, there are many demands for downsizing cabinets. Therefore, a large number of printed circuit boards are provided in the rack, and the rack is fully filled in the front-rear direction (drawing direction). The printed circuit board is provided with the dimensions described above.
[0004]
For this reason, the cabinet can be rotated 90 ° downward (the rear surface is directed upward) after the rack is pulled out from the cabinet main body so that maintenance and inspection can be easily performed from the rear surface side of the rack. As described above, a slide rail configured to be freely bent is conventionally known. The slide rail configured in this way is attached to the left and right sides of the rack, and by operating the lever provided at the front end of the slide rail, the slide rail can be held and bent in a linearly extended state Is configured.
[0005]
[Problems to be solved by the invention]
However, in the slide rail configured as described above, even if both hands can be used to pull out the rack from the cabinet, the rack is supported with one hand to operate the lever, and the lever is operated with one hand. Must be done. For this reason, there is a problem that it is difficult for the operator to rotate the rack alone, and there is a problem that the labor of the operator is increased particularly when the rack is heavy.
[0006]
The present invention has been made in view of such a problem, and an object of the present invention is to provide a slide rail which can vertically rotate a rack which is horizontally pulled out of a cabinet by a simple operation.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a slide rail according to the present invention is assembled with a housing-side slide rail member coupled to a housing and slidably movable relative to the housing-side slide rail member. And a drawer side slide rail member coupled to the member. The drawer side slide rail member is in a state where the base end member is slidably assembled to the housing side slide rail member, and is located outside the base end member in the sliding direction and is coupled to the drawer member, and is slid outward. And a tip member protruding outward from the housing-side slide rail member. The proximal member and the distal member are connected by a connecting member so as to be locked and held in a state of being linearly arranged.
[0008]
The connecting member allows the distal end member to swing up and down with respect to the base end member, and also allows the swing axis of the distal end member to move in the sliding direction with respect to the base end member, so that the base end member and the tip end member are movable. Connected. When the swinging shaft is moved inward in the sliding direction with respect to the base member and the connecting member is positioned, the base member and the front member are linearly aligned and integrally formed on the housing-side slide rail member. The base member and the distal member can be slidably moved with respect to each other, and restrict the downward swing of the distal member with respect to the proximal member from the linearly arranged position, and allow only the upward swing. When the rocking shaft is moved to the outside in the sliding direction with respect to the base member after the tip member is rocked upward with respect to the base member, A state in which the rocking of the proximal end member and the distal end member is released while allowing the vertical swinging of the downward movement of the distal end member with respect to the member. After the drawer member is slid outward from the housing with the connecting member holding the base member and the distal member in a locked state, the distal member is rocked upward by sliding the drawer member upward, and then sliding. The rocking shaft is moved outward in the direction to release the lock of the connecting member, and the drawer member is swung downward so that the distal end member extends substantially vertically downward with respect to the base end member, and the rear surface of the drawer member Faces upwards.
[0009]
According to the slide rail configured as described above, the base member and the distal member are held in a state in which the base member and the distal member are arranged in a straight line and only upward swing is allowed. When pulled, the drawer side slide rail member can be slid with respect to the housing side slide rail member, and the drawer member can be pulled out horizontally from the housing.
[0010]
Then, when the leading end member is allowed to swing upward while the drawer side slide rail member is slid and moved until the leading end member is positioned outside the housing side slide rail member, the swing shaft is moved. By moving the distal end member outward in the sliding direction , the distal end member can be pivoted upward and moved outward in the sliding direction to release the lock and release the base of the distal end member. Vertical swing with respect to the end member is also allowed. Therefore, if the hand supporting the drawer member connected to the distal end member is released, the distal end member rotates downward by its own weight, and the rear surface of the drawer member can be directed upward.
[0011]
The connecting member has an elongated hole formed in one of the proximal member and the distal member so as to extend in the sliding direction , and the other of the proximal member and the distal member is loosely fitted in the elongated hole to form a base. It is preferable to have a configuration having a connection projection for connecting the tip member to the end member such that the tip member can move in the sliding direction and swing in the vertical direction.
[0012]
Further, it is preferable that a stopper protrusion is formed on one of the base member and the distal member, and a stopper protrusion receiving groove is formed on the other of the base member and the distal member. contact stopper projection and those in a state aligned with the tip member linearly prevents rocking of the mobile and below the sliding direction relative to the proximal member of the tip member, slides from by swinging the tip member upwardly The distal end member is moved outward in the direction to release the holding of the stopper projection to allow vertical movement of the distal end member with respect to the base end member.
[0013]
With such a configuration, in a state where the base member and the distal member are arranged in a straight line, the stopper protrusion is received in the stopper protrusion receiving groove, so that the distal member is linear with respect to the base member. Are kept in line . In the state where the held aligned linearly, drawn from housing side slide rail base member also integrally has moved is blocked forward of the tip member, if pulled out the tip member Therefore, the drawer member can be pulled out horizontally from the housing.
[0014]
Even in the state where the distal member and the proximal member are held linearly as described above, the upward movement of the distal member relative to the proximal member is possible, and in the rocked state, the distal member is It becomes slidable by the length of the elongated hole with respect to the base member. Therefore, by lifting the drawer member upward to remove the stopper protrusion from the stopper protrusion receiving groove, and pulling the drawer member forward in this state, the stopper protrusion is received in the stopper receiving groove again even when the drawer member is returned to the horizontal state. Therefore, the swinging member can swing downward.
[0015]

The drawer side rail member 11 is composed of a distal end member 11a to which the rack 23 is coupled and a base end member 11b supported by the first housing side rail member 12 in a state of being extended with respect to the first housing side rail member 12. It is configured. The distal member 11a and the proximal member 11b are connected by a connecting member 14. The connecting member 14 includes a distal connecting member 14a attached to the distal member 11a and a proximal connecting member attached to the proximal member 11b. And a member 14b.
[0019]
The drawer-side rail member 11 is formed to have a substantially U-shaped cross section, and the connecting member 14 is disposed in the inner space of the drawer-side rail member 11. The distal-side connecting member 14a includes a distal-side connecting member main body 14c formed in a rectangular plate shape, and a connecting protrusion 14d and a stopper protrusion 14e projecting outward from the distal-side connecting member main body 14c. Have been. The distal-side connecting member main body 14c is attached so as to extend rearward from the distal end portion 11a, and the connecting protrusion 14d is disposed behind the distal-side connecting member main body 14c. Further, the stopper projection 14e is disposed forward of the connecting projection 14d.
[0020]
The base end side connection member 14b is formed in a plate shape similarly to the front end side connection portion main body 14c, and has an elongated hole 14f into which the connection protrusion 14d can be loosely fitted. A receiving portion 14g that can receive the stopper projection 14e is formed at the distal end portion of the proximal-side connecting member 14b. The receiving portion 14g is formed in a J-shape, and can support the lower front side of the stopper projection 14e.
[0021]
The distal-side connecting member 14a and the proximal-side connecting member 14b thus configured are connected in a state where the connecting protrusion 14d is inserted into the elongated hole 14f. This connection is performed such that the distal end side connecting member 14a is movable, and the distal end side connecting member 14a is sandwiched between the base end portion 11b and the proximal end side connecting member 14b.
[0022]
The elongated hole 14f is formed so as to extend in the front-rear direction in the base end side connection member 14b, and is formed so that the rear end portion 14h is slightly raised and the front end portion 14i is slightly lowered. ing. When the stopper protrusion 14e is received by the receiving portion 14g, the connecting protrusion 14d is located at the rear end 14h.
[0023]
In such a state, the connecting protrusion 14d has a slight catch at the rear end 14h, and the stopper protrusion 14e is received and caught by the receiving groove 14j extending upward in the receiving portion 14g. When the rack 23) is pulled out forward, the base end 11b is also drawn out with respect to the housing-side rail member 12. When the connecting projection 14d is hooked at the rear end 14h and the stopper projection 14e is received in the receiving groove 14j, the distal end 11a and the proximal end 11b are linearly aligned and locked and held.
[0024]
In the cabinet 20 configured as described above, as shown in FIG. 2, when the rack 23 is pulled forward, the drawer-side rail member 11 integrally connected by the connecting member 14 extends with respect to the housing-side rail member 12. At the same time, the first housing side rail member 12 extends with respect to the second housing side rail member 13. Here, the amount of extension of each of the rail members 11 to 13 is such that the distance L1 from the front surface 21a of the cabinet body 21 to the back surface 23b of the rack 23 in a state where each rail member is fully extended is equal to the distance between the center of the connection protrusion 14d and the rack 23. Is set so as to be longer than the distance L2 to the lower surface 23c, and the connecting member 14 is set to be completely exposed from the first housing side rail member 12.
[0025]
Thus, the upper surface 23d and the lower surface 23c can be completely exposed from the cabinet body 21 by pulling the rack 23 horizontally, so that the upper surface side of the printed circuit board (not shown) disposed in the rack 23 is provided. In addition, maintenance and inspection from the lower surface side can be easily performed.
[0026]
Next, an operation for rotating the rack 23 by 90 ° and turning the rear surface 23b upward to perform maintenance and inspection from the rear surface side of the rack 23 will be described. When the rack 23 is rotated, the rack 23 is completely pulled out as shown in FIG. 2, and as shown in FIG. 14e gets over.
[0027]
In the state where the stopper protrusion 14e has passed over the receiving portion 14g, the distal-side connecting member 14a is pivotally supported by the base-side connecting member 14b only by the connecting protrusion 14d located in the elongated hole 14f. It becomes. Therefore, the distal end portion 11a is configured to be vertically swingable with respect to the base end portion 11b, and the rack 23 is held to be able to swing vertically with respect to the cabinet body 21.
[0028]
Thus, if the force of the hand supporting the rack 23 is released, the rack 23 rotates 90 ° until the rear surface 23b faces upward as shown in FIG. By turning the rear surface 23b upward, the outside of the rear surface 23b is opened. Therefore, if the panel provided on the rear surface 23b is removed from the rack 23, the printed circuit provided in the rack 23 is removed. Maintenance inspection of the board and the like can be easily performed.
[0029]
In the slide rail of the present invention, the connecting member 114 may be configured as shown in FIG. The connecting member 114 includes a distal-side connecting member 114a and a proximal-side connecting member 114b, like the connecting member 14. Here, the distal-side connecting member 114a is formed similarly to the above-mentioned distal-side connecting member 14a with the two projections 114d and 114e, and thus detailed description is omitted here.
[0030]
As shown in FIG. 5A, the base-side connecting member 114b also has the elongated hole 114f and the receiving portion 114g, but the receiving portion 114g is more distal than the receiving portion 14g. The portion 114k is formed so as to return to the rear. Therefore, in order to swing the distal end side connecting member 114a upward, as shown in FIG. 3B, the distal end side connecting member 114a is moved upward after being moved backward. Thereafter, as shown in (C), if the connecting protrusion 114d is moved to the front end of the elongated hole, the distal end side connecting member 114a can be swung downward by passing the receiving portion 114g.
[0031]
According to the connecting member 14 configured as described above, it is possible to more reliably hold the distal-side connecting member 114a and the proximal-side connecting member 114b in a state where they are linearly extended. When the connecting member 14 is used, it is necessary to push the drawer member backward once when swinging the drawer member downward. When the rail member operates in the reduction direction, a slight resistance is applied.
[0032]
Further, as shown in FIGS. 6A, 6B, and 6C, a long hole 214f is formed in front of the base-side connecting member 214b, and a stopper projection 214e is provided behind the long hole 214f. The receiving member 214g may be provided at the rear end of the side connecting member 214a, and the connecting protrusion 214d may be provided in front of the receiving portion 214g to form the connecting member 214. Even in such a configuration, if the drawer member attached to the distal end side connection member 214a is lifted upward similarly to the connection members 14 and 114 and then pulled out to the front, the vertical movement of the drawer member can be freely performed. Become.
[0033]
【The invention's effect】
As described above, in the slide rail according to the present invention, the base member coupled to the housing and the distal member coupled to the drawer member are linearly locked and held by the coupling member. By pulling the member horizontally, the drawer member can be pulled out of the housing. Then, from the state where the drawer member is pulled out, if the drawer member is lifted upward and pulled forward without releasing or holding the hand as it is, the lock holding by the connecting member is released and the distal end with respect to the base end member is released. The member is pivotally supported in a vertically rotatable manner. Therefore, if the hand supporting the drawer member is released, the drawer member can be rotated so that the rear surface thereof faces upward.
[0034]
Here, the connecting member has a long hole formed on one of the base member and the distal member, and a connecting protrusion for loosely fitting into the long hole is provided on the other, and a stopper protrusion is provided on one of the base member or the distal member. It is preferable to form a stopper protrusion receiving groove for receiving the stopper protrusion on the other side. The stopper projection and the stopper projection receiving groove prevent the distal end member from moving outward in the sliding direction with respect to the proximal end member and swinging downward with respect to the proximal end member in a state where the proximal end member and the distal end member are linearly arranged. If the tip member is swung upward and then moved outward in the sliding direction to release the stopper projection and allow up-down swing, a simple configuration can be used to protrude from each slide rail member. It is possible to obtain a connecting member that does not need to be connected.
