Description

【０００１】
【発明の属する技術分野】
本発明は、主に通信機器収納用のキャビネット等に使用する台板の取付構造に関するものである。
【０００２】
【従来の技術】
従来、キャビネットの左右側内面に取り付けた水平支持版の前端縁に垂設した前面板部と台板の前端縁に垂設した前面板部とをねじ止めする台板の取り付け構造のものがある。これは水平支持板に台板を取り付けたうえ、この台板に機器類を取り付けて使用するが、台板を使用せずに水平支持板のみで取り付けることができる機器の場合、直接水平支持板に載せて取り付けることがあった。しかしこの場合、水平支持板の前端部に機器があたる可能性があり、水平支持板の前端縁に垂設した前面板部がデットスペースとなり、下に位置する台板に機器を収納する場合にそのデットスペース分台板を下げる必要があった。また、キャビネットの左右側部内面に基端部をもって取り付けた水平支持板に台板の取り付けは、台板が水平方向すなわち前後左右に移動するのを防止するため台板を水平支持板にねじで固定したものが普通であった。
【０００３】
【発明が解決しようとする課題】
ところが、このような従来のものにあっては、下段の水平支持板をデットスペース分下方に取り付けるので、機器を収納するスペースが減る問題がある。また、台板をねじにより固定する作業が厄介であり、さらに、台板の取り外しにも手数を要する問題があった。
【０００４】
【課題を解決するための手段】
前記の課題を解決するためになされた本発明は、キャビネット本体の左右側部内面に取り付けた水平支持板に台板の両側下方を支持する台板の取付構造において、水平支持板の前端側に係止孔を設け、また、台板の前端縁に垂設した前面板部に、この台板が水平支持板に支持させたときに前記係止孔と左右位置が一致する孔を設け、前面板部の前面から該孔に回転ブッシュを挿入したうえ該回転ブッシュに設けた係止突起を前記係止孔に係合したものである。
【０００５】
【発明の実施の形態】
次に、本発明の実施形態を説明する。１はキャビネット本体、２、２は前記キャビネット本体１の左右側部内面に基端部をもって取り付けた水平支持板であり、該水平支持板２，２はＬ型レールの水平板部２ａをもって構成して、Ｌ型レールの垂直板部２ｂをキャビネット本体１の内面に当接させるとともに水平板部２ａの前端縁に垂設した前板部２ｃの外側に連設した掛鉤部２ｄをキャビネット本体１の内面に設けた係合孔に係合させて取り付けられている。
【０００６】
３は前記水平支持板２、２に両側下面を支持されて取り付けられる台板である。この台板３は両側前端縁に垂設した前板部３１の下端後方に内鍔板部３２を連設したうえ該内鍔板部３２の外側に切欠部３３を形成して、該切欠部３３を前記水平支持板２の前端縁下方に設けた係止片２１に係合させて、該台板３が水平支持板２、２上で前後左右方向に移動するのを防止するものである。なお、図示の実施形態にあっては係止片２１は水平支持板２としたＬ型レールの水平板部２ａの前端縁に垂設した前板部２ｃの内側下方に突設したものであるが、Ｌ型レールの垂直板部２ｂの前端縁に折曲形成してもよい。また、台板３の後側の取り付けにいてこの実施形態においては、台板３の裏側に掛鉤部３５を設け、水平支持板２に該掛鉤部３５に対応する箇所に孔２３を設けて、掛鉤部３５と孔２３を係合させて取り付けているが、取り付け手段はこれに限定されないことは勿論である。
【０００７】
また、水平支持板２、２の前端側には係止孔２２が設けてあり、他方これに支持される台板３の前端縁に垂設した前桁板部３１には、この台板３が水平支持板２、２に支持させたときに前記係止孔２２と左右位置が一致する横長孔３４が設けてあり、前桁板部３１の前面から該横長孔３４に回転ブッシュ４を挿入したうえ該回転ブッシュ４を回転させ該回転ブッシュ４に設けた係止突起４１を前記係止孔２２に係合させている。このように台板３の左右の２箇所で係止突起４１と係止孔２２が係合されているので、台板２は水平方向に移動することがないものである。また、回転ブッシュ４は水平支持板２の下面に当接しているので、該回転ブッシュ４が挿入されている台板３は水平支持板２から浮き上がるおそれがなくなり、ねじで強固に止める必要はない。なお、この実施形態では横長孔３４に回転ブッシュ４を挿入しているが、回転ブッシュが容易に外れなければ孔の形状は横長孔でなくともよい。
【０００８】
さらに、この実施形態においては、台板３の内鍔板部３２に設けた切欠部３３を水平支持板２の前端下方に設けた係止片２１に係合させて、台板３を左右の水平支持板２、２取り付けた構造と、回転ブッシュ４により台板３を水平支持板２、２に取り付けする構造を併せて設けているが、どちらか一方のみ取り付けることが可能である。
【０００９】
【発明の効果】
前記したように、本発明にあっては、回転ブッシュより台板を水平支持板に取り付けする構造としたから、台板を使用せずに直接機器類を水平支持板に取り付ける場合にデットスペースがなくなり、機器の収納スペースが広くすることができる。また、キャビネットの左右側部内面に取り付けた水平支持板に台板の取り付けをねじをもって固定する必要がないので台板の取り付け取り外しが容易な台板の取付構造を提供したものである。
従って、従来の問題点を解決したものであり、業界にもたらす益大なものである。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a base plate used mainly for a cabinet for storing communication equipment.
[0002]
[Prior art]
Conventionally, there is a base plate mounting structure in which a front plate part suspended from the front edge of a horizontal support plate attached to the left and right inner surfaces of the cabinet and a front plate part suspended from the front edge of the base plate are screwed. . This is done by attaching a base plate to the horizontal support plate and attaching the equipment to this base plate. However, in the case of equipment that can be attached only by the horizontal support plate without using the base plate, the horizontal support plate is used directly. Sometimes it was mounted on. However, in this case, there is a possibility that the device hits the front end of the horizontal support plate, and the front plate hanging from the front end edge of the horizontal support plate becomes a dead space, and the device is stored in the base plate located below. The dead space has to be lowered. In addition, the base plate is attached to the horizontal support plate attached to the inner surface of the left and right sides of the cabinet with the base end portion. What was fixed was normal.
[0003]
[Problems to be solved by the invention]
However, in such a conventional apparatus, since the lower horizontal support plate is attached below the dead space, there is a problem of reducing the space for storing the equipment. Further, it is troublesome to fix the base plate with screws, and there is a problem that it takes time to remove the base plate.
[0004]
[Means for Solving the Problems]
The present invention, which has been made to solve the above-mentioned problems, is a mounting structure for a base plate that supports the lower side of the base plate on the horizontal support plate attached to the inner surfaces of the left and right sides of the cabinet body, on the front end side of the horizontal support plate. A locking hole is provided, and a front plate portion suspended from the front edge of the base plate is provided with a hole whose left and right positions coincide with the base plate when the base plate is supported by a horizontal support plate. A rotating bush is inserted into the hole from the front surface of the face plate portion, and a locking protrusion provided on the rotating bush is engaged with the locking hole.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described. Reference numeral 1 denotes a cabinet body, 2 and 2 are horizontal support plates attached to the inner surfaces of the left and right side portions of the cabinet body 1 with base ends, and the horizontal support plates 2 and 2 are composed of horizontal plate portions 2a of L-shaped rails. Then, the vertical plate portion 2b of the L-shaped rail is brought into contact with the inner surface of the cabinet body 1 and the hanging portion 2d continuously provided on the outside of the front plate portion 2c suspended from the front edge of the horizontal plate portion 2a is attached to the cabinet body 1. It is attached by engaging with an engagement hole provided on the inner surface.
[0006]
Reference numeral 3 denotes a base plate which is attached to the horizontal support plates 2 and 2 while supporting lower surfaces on both sides. The base plate 3 has an inner flange plate portion 32 continuously provided behind the lower end of a front plate portion 31 that is suspended from the front edge of both sides, and a notch portion 33 is formed outside the inner flange plate portion 32. 33 is engaged with a locking piece 21 provided below the front edge of the horizontal support plate 2 to prevent the base plate 3 from moving in the front / rear and left / right directions on the horizontal support plates 2 and 2. . In the illustrated embodiment, the locking piece 21 is provided so as to protrude below the front plate portion 2c suspended from the front end edge of the horizontal plate portion 2a of the L-shaped rail as the horizontal support plate 2. However, it may be bent at the front edge of the vertical plate portion 2b of the L-shaped rail. In addition, in this embodiment for mounting on the rear side of the base plate 3, a hook portion 35 is provided on the back side of the base plate 3, and a hole 23 is provided in a position corresponding to the hook portion 35 on the horizontal support plate 2, Although the hook portion 35 and the hole 23 are engaged and attached, the attachment means is of course not limited to this.
[0007]
Further, a locking hole 22 is provided on the front end side of the horizontal support plates 2, 2, and on the other hand, the front girder plate portion 31 suspending from the front end edge of the base plate 3 supported by this has a base plate 3. Is provided with a horizontally long hole 34 whose left and right positions coincide with the locking hole 22 when supported by the horizontal support plates 2 and 2, and the rotating bush 4 is inserted into the horizontally long hole 34 from the front surface of the front girder plate portion 31. In addition, the rotating bush 4 is rotated to engage the locking projection 41 provided on the rotating bush 4 with the locking hole 22. As described above, since the locking projections 41 and the locking holes 22 are engaged at the two left and right positions of the base plate 3, the base plate 2 does not move in the horizontal direction. Further, since the rotary bush 4 is in contact with the lower surface of the horizontal support plate 2, the base plate 3 into which the rotary bush 4 is inserted is not likely to be lifted from the horizontal support plate 2 and does not need to be firmly fixed with screws. . In this embodiment, the rotating bush 4 is inserted into the horizontally long hole 34, but the shape of the hole may not be a horizontally long hole if the rotating bush is not easily removed.
[0008]
Furthermore, in this embodiment, the notch 33 provided in the inner flange plate portion 32 of the base plate 3 is engaged with the locking piece 21 provided below the front end of the horizontal support plate 2 so that the base plate 3 can be The structure in which the horizontal support plates 2 and 2 are attached and the structure in which the base plate 3 is attached to the horizontal support plates 2 and 2 by the rotating bush 4 are provided together, but only one of them can be attached.
[0009]
【The invention's effect】
As described above, in the present invention, since the base plate is attached to the horizontal support plate from the rotating bush, the dead space is increased when the devices are directly attached to the horizontal support plate without using the base plate. The storage space for the device can be widened. Further, since it is not necessary to fix the mounting of the base plate to the horizontal support plate attached to the inner surface of the left and right side portions of the cabinet with a screw, a mounting structure for the base plate that can be easily attached and detached is provided.
Therefore, it is a solution to the conventional problems and is a great benefit for the industry.
