Description

この発明は、電子機器に用いられるカバーの取り付け構造に関するものである。   The present invention relates to a cover mounting structure used in an electronic device.

電子機器には、サブカバーを取り付けて接続ケーブルや調整ボリュームなどを見えなくしたものがある。   Some electronic devices have a sub-cover attached to obscure the connection cable and adjustment volume.

例えば、（特許文献１）に示すものは、電話装置の主装置で、図８に示すように、装置本体１と装置本体１を被うカバー２とで構成されている。また、前記カバー２は、装置本体１の前面の上部を被うメインカバー３と、下部を被うサブカバー（サブカバー）４とで構成され、前記サブカバー４は、装置本体１の工事部５を被う。
ここで、工事部５は、主装置の配線部などケーブルとの接続部や調整用ボリュームなどを設けた部分である。 For example, what is shown in (Patent Document 1) is a main device of a telephone device, and includes a device main body 1 and a cover 2 covering the device main body 1 as shown in FIG. The cover 2 includes a main cover 3 that covers the upper part of the front surface of the apparatus main body 1 and a sub cover (sub cover) 4 that covers the lower part. The sub cover 4 is a construction part of the apparatus main body 1. 5
Here, the construction portion 5 is a portion provided with a connection portion with a cable, such as a wiring portion of the main apparatus, and an adjustment volume.

このサブカバー４には、図９に示すように、上端（背面側）に係止用のツメ６、７と係合用のリング部材８が設けてある。ここで、係止用のツメ６，７は、上端の中央に設けられた主ツメ６とその主ツメ６の左右に設けた副ツメ７とで構成される。また、上端の左右に設けられたリング部材８は、途中に括れ嵌入部を設けた形状になっている。   As shown in FIG. 9, the sub-cover 4 is provided with locking claws 6 and 7 and an engaging ring member 8 on the upper end (back side). Here, the locking claws 6, 7 are composed of a main claw 6 provided at the center of the upper end and subclaws 7 provided on the left and right of the main claw 6. Further, the ring members 8 provided on the left and right of the upper end have a shape in which a constricted insertion portion is provided in the middle.

一方、装置本体１の工事部５には、上方に主ツメ６用の第１と第２の挿入穴９，１０、および副ツメ７用の嵌合口１１と係止用リブ１２、それに、前記リング部材８を嵌める動作軸１３が設けてある。ここで、動作軸１３は、真ん中に空隙を設けた左右一対の軸から構成されたもので、前記動作軸１３の空隙に、サブカバー４のリング部材８の括れ部分を通すことで、サブカバー４を脱着できるようになっている。   On the other hand, in the construction section 5 of the apparatus main body 1, the first and second insertion holes 9 and 10 for the main claw 6, the fitting opening 11 and the locking rib 12 for the sub claw 7, An operating shaft 13 for fitting the ring member 8 is provided. Here, the operation shaft 13 is composed of a pair of left and right shafts provided with a gap in the middle. By passing the constricted portion of the ring member 8 of the sub cover 4 through the gap of the operation shaft 13, the sub cover 4 can be removed.

また、リング部材８で動作軸１３に取り付けたサブカバー４は、開閉自在に支持されるようになっており、こうして取り付けられたサブカバー４は、上端のツメ６，７を工事部の挿入穴９あるいは嵌合口１１に嵌入することで、サブカバーを開けた状態で保持したり、閉じた状態で維持したりできるようになっている。   The sub-cover 4 attached to the operating shaft 13 by the ring member 8 is supported so as to be freely opened and closed. The sub-cover 4 thus attached has claws 6 and 7 at the upper end inserted into the insertion holes of the construction part. 9 or the fitting opening 11 allows the sub-cover to be held in an open state or maintained in a closed state.

すなわち、サブカバー４を開ける場合は、図８のように、サブカバー４の主ツメ６の上をメインカバー３の表面から押して、主ツメ６と第１の挿入穴９の奥（メインカバー３内）に設けたリブとの係合を解除し、サブカバーを下方にスライドする。そして、サブカバー４を開けて、主ツメ６を第２の挿入穴１０に嵌入する。同時に、副ツメ７をリブ１２に当接させて嵌合口１１に嵌めることで開いた状態を保持する。一方、サブカバー４を閉じた状態で保持する場合は、サブカバー４を閉じて、上方にスライドさせる。そして、主ツメ６を第１の挿入穴９に嵌入して中のリブと係合させればよい。
このように、このサブカバー４は、ネジ止めせずに開いた状態や閉じた状態を保てるというものである。
特開２００６−１４７６７８号公報 That is, when opening the sub cover 4, as shown in FIG. 8, the top of the main claw 6 of the sub cover 4 is pushed from the surface of the main cover 3, and the back of the main claw 6 and the first insertion hole 9 (the main cover 3 Release the engagement with the rib provided on the inner side, and slide the sub cover downward. Then, the sub cover 4 is opened, and the main claw 6 is inserted into the second insertion hole 10. At the same time, the sub-claw 7 is brought into contact with the rib 12 so as to be fitted into the fitting port 11 to maintain the opened state. On the other hand, when the sub cover 4 is held in a closed state, the sub cover 4 is closed and slid upward. Then, the main claw 6 may be fitted into the first insertion hole 9 and engaged with the rib inside.
Thus, the sub-cover 4 can be kept open or closed without being screwed.
JP 2006-147678 A

しかしながら、上記のサブカバーの取り付け構造では、工事部にリブ、嵌合口や動作軸などを設けなければならないため、工事部がメインカバーより露出している必要がある。しかも、工事部に、リブ、嵌合口や動作軸などを設けるための余分なスベースを確保しなければならない問題もある。   However, in the above-described sub-cover mounting structure, since the rib, the fitting port, the operating shaft, and the like must be provided in the construction portion, the construction portion needs to be exposed from the main cover. Moreover, there is a problem that an extra sbase for providing a rib, a fitting port, an operation shaft, and the like must be secured in the construction section.

また、動作軸を工事部内に設けたために、サブカバーを開けると、開けたサブカバーが工事部に被さって作業がし難い問題がある。   In addition, since the operation shaft is provided in the construction section, there is a problem that when the sub cover is opened, the opened sub cover covers the construction section and it is difficult to work.

さらに、サブカバーを外して使用する場合は、リブや動作軸などの取り付け機構の一部が露呈するので見苦しい上に、露呈したリブや動作軸は尖っているので危険である。   Further, when the sub-cover is used after removing, a part of the mounting mechanism such as the rib and the operating shaft is exposed, which is unsightly, and the exposed rib and the operating shaft are sharp, which is dangerous.

加えて、サブカバーの保持は、主ツメや副ツメを挿入穴や嵌入口に係合させるという方法である。そのため、係合させる際に要する力は、主ツメ、副ツメ、挿入穴、嵌入口の寸法や製作精度などで決まってしまうので、その調節は難しく、開けた状態や閉じた状態で保持するのに失敗する問題がある。   In addition, the holding of the sub cover is a method in which the main claw and the sub claw are engaged with the insertion hole and the insertion opening. For this reason, the force required for engagement is determined by the dimensions and manufacturing accuracy of the main claw, sub claw, insertion hole, and insertion opening, so adjustment is difficult, and it must be held in an open or closed state. There is a problem that fails.

そこで、この発明の課題は、工事部の有無に係わらず、サブカバーを取り付けられるようにすること、その際、工事部にサブカバーを取り付けるための余分なスペースを要しないようにすること、作業の邪魔にならないように開けることができるようにすること、サブカバーを外した際に、取り付け機構が露出しないようにすること、開閉に要する力を調整できるようにすることである。   Accordingly, an object of the present invention is to allow a sub cover to be attached regardless of the presence or absence of a construction part, and in that case, to eliminate the need for extra space for attaching the sub cover to the construction part. It is to be able to be opened so that it does not get in the way, to prevent the attachment mechanism from being exposed when the sub cover is removed, and to be able to adjust the force required for opening and closing.

上記の課題を解決するため、この発明では、シャーシを被うメインカバーと、そのメインカバーの被いを除いた前記シャーシの開放部に、アームで開閉自在に取り付けられるサブカバーとで構成され、前記メインカバーと前記シャーシの開放部の両端との間に、サブカバーのアームを挿入する隙間が形成され、その隙間のシャーシ側にネジ孔が設けられるとともに、前記ネジ孔と対向する貫通孔がメインカバーに設けられ、かつ、前記貫通孔の周囲にアームと接する当接部が形成され、前記当接部に貫通孔から外向きに伸びる突条あるいは溝が形成されており、一方サブカバーは、両端にアームが設けられ、そのアームの先端に貫通孔が設けられるとともに、その貫通孔を設けた先端に、アームを隙間に挿入した際にメインカバーの当接部と接する摺動部が設けられ、その摺動部には貫通孔から外向きに伸びる溝あるいは突条が設けられおり、前記サブカバーのアームを開放部の両端に形成される隙間に挿入し、前記シャーシのネジ孔、アームの貫通孔、メインカバーの貫通孔を一致させて、メインカバーの貫通孔からネジを挿通してネジ止めし、アームの摺動部の溝あるいは突条と、メインカバーの当接部の突条あるいは溝を係合させてサブカバーを開閉するようにした構成を採用したのである。   In order to solve the above-described problems, the present invention comprises a main cover that covers the chassis, and a sub-cover that can be opened and closed by an arm on the open portion of the chassis excluding the cover of the main cover, A gap for inserting the arm of the sub cover is formed between the main cover and both ends of the open portion of the chassis, a screw hole is provided on the chassis side of the gap, and a through hole facing the screw hole is provided. A contact portion provided on the main cover and in contact with the arm is formed around the through hole, and a protrusion or groove extending outward from the through hole is formed in the contact portion, while the sub cover is The arm is provided at both ends, a through hole is provided at the tip of the arm, and when the arm is inserted into the gap at the tip provided with the through hole, The sliding portion is provided with a groove or a ridge extending outward from the through hole, and the sub cover arm is inserted into a gap formed at both ends of the opening portion, Match the screw holes on the chassis, the through holes in the arm, and the through holes in the main cover, insert screws through the through holes in the main cover, and fix them. A configuration is adopted in which the sub-cover is opened and closed by engaging the protrusions or grooves of the contact portion.

このような構成を採用したことにより、サブカバーは、開放部両端のシャーシとメインカバーとの隙間にフック状のアームを挿入して取り付ける。このため、工事部の有無に係わらず取り付けることができる。また、このように、サブカバーは、開放部両端のシャーシとメインカバーとの隙間に取り付けるので、工事部にサブカバーを取り付けるための余分なスペースを必要としない。このとき、アームでサブカバーをメインカバーの上に持ち上げるようにすれば、サブカバーが作業の邪魔にならないように開けた状態で保持できる。また、サブカバーはネジ止めしてあるので、ネジを外せば、簡単に取り外すことができる。その際、取り付け機構は、開放部両端のシャーシとメインカバーとの隙間に形成しているので露出しない。また、サブカバーは、シャーシのネジ孔、アームの貫通孔、メインカバーの貫通孔を一致させて、ネジ止めする構造なので、ネジの締め付けで係合量を決めれば、開閉に要する力を調整できる。また、このとき、アームとメインカバーは、当接部の溝と摺動部の突条とを係合させて係止するので、サブカバーを開けた状態や閉じた状態でネジ止めせずにしっかりと保持できる。さらに、ネジを締め付ければ確実に固定できる。   By adopting such a configuration, the sub cover is attached by inserting a hook-like arm into the gap between the chassis and the main cover at both ends of the open portion. For this reason, it can be attached regardless of the presence or absence of a construction section. Further, as described above, since the sub cover is attached to the gap between the chassis and the main cover at both ends of the open part, no extra space is required for attaching the sub cover to the construction part. At this time, if the sub cover is lifted on the main cover by the arm, the sub cover can be held open so as not to interfere with the work. Moreover, since the sub cover is screwed, it can be easily removed by removing the screw. At this time, the attachment mechanism is not exposed because it is formed in the gap between the chassis and the main cover at both ends of the opening. In addition, the sub cover has a structure in which the screw hole of the chassis, the through hole of the arm, and the through hole of the main cover are aligned and screwed. . At this time, the arm and the main cover are locked by engaging the groove of the abutting portion and the protrusion of the sliding portion, so that the sub cover is not screwed in the opened state or the closed state. Can hold firmly. Furthermore, it can be securely fixed by tightening the screw.

このとき、サブカバーがケーブルを保護する保護カバーとしたりする構成を採用できる。   At this time, a configuration in which the sub cover is used as a protective cover for protecting the cable can be employed.

この発明は、上記のように構成したことにより、工事部の有無に係わらず、取り付け機構を少ないスペースで実現し、外観に出さないようにできる。しかも、開閉に要する力の調整や開閉状態での固定も簡単にできる。   Since the present invention is configured as described above, the attachment mechanism can be realized in a small space regardless of the presence or absence of the construction portion, and the appearance can be prevented. In addition, the force required for opening and closing can be easily adjusted and fixed in the opened and closed state.

以下、この発明を実施するための最良の形態を図面に基づいて説明する。
図１で示すこの形態は、無線ＬＡＮのアクセスポイントに本願のカバーの取り付け構造を適用したものである。 The best mode for carrying out the present invention will be described below with reference to the drawings.
In this embodiment shown in FIG. 1, the cover mounting structure of the present application is applied to a wireless LAN access point.

前記アクセスポイントは、メインカバー２１をシャーシ２２の前方に取り付ける構造で、そのメインカバー２１の被いを除いた開放部（ここでは、シャーシ２２の側方）２３に、図２のように、サブカバー２０を取り付ける構造となっている。   The access point has a structure in which the main cover 21 is attached to the front of the chassis 22, and an open portion (here, the side of the chassis 22) 23 excluding the covering of the main cover 21 is connected to the sub-point as shown in FIG. The cover 20 is attached.

この形態のメインカバー２１とサブカバー２０は樹脂製で、メインカバー２１は、図１のように、シャーシ２２の前面（図では上面）と開放部２３を除く側面を被う形状のものである。
前記開放部２３は、メインカバー２１の被いを除き、ケーブル端子、リセットスイッチなどを設けた部分で、従来例で工事部と称した箇所に相当する部分である。 The main cover 21 and the sub cover 20 in this form are made of resin, and the main cover 21 has a shape that covers the front surface (upper surface in the drawing) of the chassis 22 and the side surface except the opening 23 as shown in FIG. .
The open portion 23 is a portion provided with a cable terminal, a reset switch, and the like except for the covering of the main cover 21 and is a portion corresponding to a place called a construction portion in the conventional example.

この開放部２３の両端には、図３（ａ）、図３（ｂ）に示すように、隙間２４が形成されている。前記隙間２４は、シャーシ２２とメインカバー２１との間に形成したもので、その大きさは、後述するサブカバー２０のアーム２５を挿入できる寸法に設定してある。
また、この隙間２４を形成するシャーシ２２側には、図１のように、シャーシ２２を折り曲げて支持部２６を形成し、その支持部２６にネジ孔２７を設けた構成としてある。他方、メインカバー２１側には、支持部（シャーシ２２側の）２６のネジ孔２７と対向する部分に貫通孔２８を設け、この貫通孔２８の周囲に当接部２９を形成してある。
また、前記当接部２９は、後述のサブカバー２０のアーム２５と接する部分で、図４のような半楕円形の台座となっている。この当接部２９には、突条３０を形成してある。前記突条３０は、貫通孔２８から外向き（シャーシに対して前方方向）に形成した直方体形状のもので、シャーシ２２に取り付けた際に、図４のように、シャーシ２２に対して垂直になる。 As shown in FIG. 3A and FIG. 3B, gaps 24 are formed at both ends of the opening 23. The gap 24 is formed between the chassis 22 and the main cover 21, and the size of the gap 24 is set such that an arm 25 of the sub cover 20 described later can be inserted.
Further, as shown in FIG. 1, the chassis 22 is bent to form a support portion 26 on the chassis 22 side where the gap 24 is formed, and a screw hole 27 is provided in the support portion 26. On the other hand, on the main cover 21 side, a through hole 28 is provided in a portion of the support portion (on the chassis 22 side) facing the screw hole 27, and a contact portion 29 is formed around the through hole 28.
Further, the abutting portion 29 is a portion in contact with an arm 25 of the sub-cover 20 described later, and is a semi-elliptical pedestal as shown in FIG. A protrusion 30 is formed on the contact portion 29. The protrusion 30 has a rectangular parallelepiped shape formed outward from the through hole 28 (forward direction with respect to the chassis), and when attached to the chassis 22, the protrusion 30 is perpendicular to the chassis 22 as shown in FIG. 4. Become.

一方、サブカバー２０は、開放部２３と同幅に形成したカバー本体の両端に、アーム２５を設けた構成となっている。前記アーム２５は、略「コ」の字形に形成されたカバー本体の折り曲げ部分の上端に設けてある。このアーム２５は、「ク」の字形をしたフック状のもので、このフックは、サブカバー２０を開放部２３に取り付けた際に、フックの開口が、図５のように、シャーシ２２の前方（面）側になるように設けてある。また、アーム２５は、フックの先端に貫通孔３１を設け、その貫通孔３１の周囲に摺動部３２を設けてある。
この摺動部３２は、アーム２５を開放部２３の隙間２４に挿入した際、図３（ａ）、図３（ｂ）のように、メインカバー２１の当接部２９と接する側に形成してある。すなわち、アーム２５の外側を図１のように切り欠いて厚みを薄くし、その薄くした摺動部３２が当接部２９に係合するようにしてある。こうすることで、摺動部３２と当接部２９を係合させた際に、厚みが増して隙間２４が大きくなるのを防止してコンパクト化を図っている。 On the other hand, the sub-cover 20 has a configuration in which arms 25 are provided at both ends of a cover main body formed to have the same width as the opening 23. The arm 25 is provided at the upper end of the bent portion of the cover body formed in a substantially “U” shape. The arm 25 has a hook shape with a “K” shape. When the sub cover 20 is attached to the opening 23, the hook opening is located at the front of the chassis 22 as shown in FIG. 5. It is provided on the (surface) side. The arm 25 has a through hole 31 at the tip of the hook, and a sliding portion 32 around the through hole 31.
The sliding portion 32 is formed on the side of the main cover 21 that contacts the contact portion 29 as shown in FIGS. 3A and 3B when the arm 25 is inserted into the gap 24 of the opening portion 23. It is. That is, the outer side of the arm 25 is cut away as shown in FIG. 1 to reduce the thickness, and the reduced sliding portion 32 is engaged with the contact portion 29. By doing so, when the sliding portion 32 and the abutting portion 29 are engaged, the thickness is prevented from increasing and the gap 24 is prevented from becoming larger, thereby achieving a compact size.

前記摺動部３２には、２本の溝３３ａ、ｂが設けてある。前記溝３３ａ、ｂは、メインカバー２１の当接部２９の突条３０と係合させるための直方体形状のもので、２本の溝３３ａ、ｂは貫通孔３１から９０°の間隔をおいて設けられている。すなわち、一方の溝３３ａは、サブカバー２０を開放部２３に取り付けた際に、貫通孔３１から外向き（前方）に伸びるように形成し、他方の溝３３ｂは、貫通孔３１から９０°の間隔をおいて、外向き（側方方向）に伸びるように形成してある。   The sliding portion 32 is provided with two grooves 33a and 33b. The grooves 33a and 33b have a rectangular parallelepiped shape for engaging with the protrusion 30 of the contact portion 29 of the main cover 21, and the two grooves 33a and 33b are spaced from the through hole 31 by 90 °. Is provided. That is, one groove 33 a is formed to extend outward (forward) from the through hole 31 when the sub cover 20 is attached to the opening 23, and the other groove 33 b is 90 ° from the through hole 31. It is formed to extend outward (lateral direction) at intervals.

ちなみに、サブカバー２０の下端は、内側に湾曲させてあるのは、遮蔽効果と端部が先鋭にならないようにして安全性を図ったものである。また、アーム２５の大きさは、後述のように、サブカバー２０を閉じた状態でメインカバー２１に連結し、かつ、開いた状態で、図６のようにメインカバー２１の上に位置するように大きさを形成したもので、メインカバー２１に合わせて適宜決められるものである。なお、符合３５は、ケーブル挿通用の孔で、切り込み付き遮蔽板が取り付けてある。   Incidentally, the lower end of the sub-cover 20 is curved inward in order to ensure the shielding effect and prevent the end from becoming sharp. As will be described later, the size of the arm 25 is such that it is connected to the main cover 21 with the sub-cover 20 closed and positioned on the main cover 21 as shown in FIG. The size is formed and is appropriately determined according to the main cover 21. In addition, the code | symbol 35 is a hole for cable penetration, and the shielding board with a notch is attached.

この形態は、上記のように構成され、この形態の無線ＬＡＮのアクセスポイントは、図１のように、シャーシ２２にメインカバー２１を取り付けた状態のものに、サブカバー２０を取り付ける。   This embodiment is configured as described above, and the wireless LAN access point of this embodiment has the sub cover 20 attached to the chassis 22 with the main cover 21 attached thereto as shown in FIG.

このサブカバー２０の取り付けは、メインカバー２１の被いが除かれた開放部２３に取り付ける。このとき、サブカバー２０は、アーム２５の設けられた側を開放部２３に向け、アーム２５を開放部２３の両端の隙間２４に滑り込ませる。次に、滑り込ませたアーム２５の摺動部３２を図３（ａ）、図３（ｂ）のように、シャーシ２２の支持部２６とメインカバー２１の当接部２９の間に入れて、シャーシ２２の支持部２６のネジ孔２７、アーム２５の摺動部３２の貫通孔３１およびメインカバー２１の貫通孔２８を一致させる。そして、その一致させた孔２８、２９、３１にネジ３６を挿通してネジ止めする。このとき、ネジ３６の締め付け量は、サブカバー２０を動かしながら調整すれば良い。   The sub cover 20 is attached to the open portion 23 from which the main cover 21 is removed. At this time, the sub cover 20 directs the side on which the arm 25 is provided to the opening 23, and slides the arm 25 into the gap 24 at both ends of the opening 23. Next, as shown in FIGS. 3A and 3B, the sliding portion 32 of the arm 25 that has been slid in is inserted between the support portion 26 of the chassis 22 and the abutting portion 29 of the main cover 21, The screw hole 27 of the support portion 26 of the chassis 22, the through hole 31 of the sliding portion 32 of the arm 25, and the through hole 28 of the main cover 21 are matched. Then, screws 36 are inserted into the holes 28, 29, and 31 that are made to coincide with each other and fixed with screws. At this time, the tightening amount of the screw 36 may be adjusted while moving the sub cover 20.

このように取り付けたサブカバー２０は、閉じた状態のときは、図５のように、メインカバー２１の当接部２９の突条３０に、アーム２５の摺動部３２の溝（一方）３３ａが嵌り仮固定される。また、開いたときには、メインカバー２１の当接部２９の突条３０に摺動部３２の他方の溝３３ｂが嵌り、仮固定される。このように、当接部２９の溝３３ａ、ｂと摺動部３２の突条３０とを係合させて係止するので、サブカバー２０を開けた状態や閉じた状態でネジ止めせずにしっかりと保持できる。
このとき、突条３０に溝３３ａ、ｂが嵌る際にクリック感とクリック音を発するので、係止状態を確実に把握できる。 When the sub-cover 20 attached in this manner is in a closed state, the groove (one side) 33a of the sliding portion 32 of the arm 25 is formed on the protrusion 30 of the contact portion 29 of the main cover 21 as shown in FIG. Is temporarily fixed. Further, when opened, the other groove 33b of the sliding portion 32 is fitted into the protrusion 30 of the contact portion 29 of the main cover 21 and temporarily fixed. In this way, the grooves 33a, b of the contact portion 29 and the protrusions 30 of the sliding portion 32 are engaged and locked, so that the sub cover 20 can be opened or closed without being screwed. Can hold firmly.
At this time, when the grooves 33a and b are fitted into the protrusion 30, a click feeling and a click sound are emitted, so that the locked state can be reliably grasped.

また、開いたサブカバー２０は、図６のように、アーム２５を「ク」の字のフック状に形成したことによって、メインカバー２１の上に持ち上げることができるので、作業の邪魔にならず、接続作業などが楽にできる。作業後は、サブカバー２０を閉じて、しっかりと固定する場合は、当接部２９の溝３３ａ、ｂに摺動部３２の突条３０を嵌めた状態でネジ３６を締め付ければ、強固な本固定ができる。   Further, as shown in FIG. 6, the opened sub-cover 20 can be lifted on the main cover 21 by forming the arm 25 in the shape of a “K” -shaped hook, so that it does not disturb the work. , Connecting work can be done easily. After the work, when the sub-cover 20 is closed and firmly fixed, if the screw 36 is tightened with the protrusion 30 of the sliding portion 32 fitted in the grooves 33a and 33b of the contact portion 29, the sub-cover 20 is firmly fixed. The book can be fixed.

すなわち、メインカバー２１とサブカバー２０は、いずれも樹脂製である。メインカバー２１は、サブカバー２０のアーム２５を挟み込んでシャーシ２２にネジ止めされる。このとき、メインカバー２１とサブカバー２０は、いずれも樹脂製であるから、ネジ３６を緩く締めた仮止の状態であれば、アーム２５の溝３３ａ、３３ｂにメインカバー２１の突条３０が係合した状態であっても、アーム２５は内側に、メインカバー２１は外側に撓むことで、サブカバー２０を開閉することが可能である。そのため、ネジ３６を締める強さによって、サブカバー２０の開閉ができない本固定状態と、サブカバー２０の開閉可能な仮固定状態とを調整することができるというものである。   That is, the main cover 21 and the sub cover 20 are both made of resin. The main cover 21 is screwed to the chassis 22 with the arm 25 of the sub cover 20 interposed therebetween. At this time, since the main cover 21 and the sub cover 20 are both made of resin, the protrusions 30 of the main cover 21 are formed in the grooves 33a and 33b of the arm 25 in a temporarily fixed state where the screws 36 are loosely tightened. Even in the engaged state, the sub cover 20 can be opened and closed by bending the arm 25 inward and the main cover 21 outward. For this reason, the strength of tightening the screw 36 can adjust the final fixed state where the sub cover 20 cannot be opened and closed and the temporarily fixed state where the sub cover 20 can be opened and closed.

また、このとき、メインカバー２１とサブカバー２０は、いずれも樹脂製であるから。突条３０が溝３３ａ、３３ｂに嵌ったり外れたりしても、突条３０と溝３３ａ、３３ｂとは大きく磨耗することはない。   At this time, the main cover 21 and the sub cover 20 are both made of resin. Even if the protrusion 30 fits in or disengages from the grooves 33a and 33b, the protrusion 30 and the grooves 33a and 33b do not wear significantly.

一方、このサブカバー２０は、開放部２３の両端の隙間２４に、フック状のアーム２５を挿入して取り付ける。このため、工事部の有無に係わらず取り付けることができる。したがって、工事部５にサブカバー２０を取り付けるための余分なスペースを要しない。
また、サブカバー２０はネジ３６を外せば、簡単に取り外すことができる。その際、取り付け構造は、開放部２３両端の隙間２４の中なので露出しない。また、サブカバー２０は、シャーシ２２の支持部２６のネジ孔２７、アーム２５の貫通孔３１、メインカバー２１の貫通孔２８を一致させネジ３６で止める構造である。そのため、ネジ３６の締め付けで当接部２９と摺動部３２との係合量を調整すれば、開閉に要する力を決められる。このとき、アーム２５とメインカバー２１は、当接部２９の溝３３ｂと摺動部３２の突条３０とを係合させてネジ止めするのでしっかりと保持できる On the other hand, the sub-cover 20 is attached by inserting hook-like arms 25 into the gaps 24 at both ends of the opening 23. For this reason, it can be attached regardless of the presence or absence of a construction section. Therefore, an extra space for attaching the sub cover 20 to the construction part 5 is not required.
The sub cover 20 can be easily removed by removing the screw 36. At that time, the mounting structure is not exposed because it is in the gap 24 at both ends of the opening 23. The sub-cover 20 has a structure in which the screw hole 27 of the support portion 26 of the chassis 22, the through-hole 31 of the arm 25, and the through-hole 28 of the main cover 21 are aligned with each other and fixed with screws 36. Therefore, if the amount of engagement between the contact portion 29 and the sliding portion 32 is adjusted by tightening the screw 36, the force required for opening and closing can be determined. At this time, the arm 25 and the main cover 21 can be firmly held because the groove 33b of the contact portion 29 and the protrusion 30 of the sliding portion 32 are engaged and screwed together.

また、この形態では、アーム２５の摺動部３２に溝３３ａ、ｂを形成し、メインカバー２１の当接部２９に突条３０を設けたが、アーム２５の摺動部３２に溝３３ａ、ｂに換えて２本の突条３０を設け、メインカバー２１の当接部２９に突条３０に換えて１本の溝３３ａを設けるようにしても同様の作用効果を得ることができる。
また、この形態では、摺動部３２に溝３３ａ、３３ｂを２本設けたものを示したが、これに限定されるものではない。例えば、前記２本の溝３３ａ、３３ｂの間に溝を設ければ、その間でのサブカバー２０の複数の角度（多段階）での保持ができる。同様に、突条３０を複数本設けることで、複数の角度でのサブカバー２０の保持ができる。 In this embodiment, grooves 33 a and b are formed in the sliding portion 32 of the arm 25, and the protrusions 30 are provided in the contact portion 29 of the main cover 21. However, the grooves 33 a and b are formed in the sliding portion 32 of the arm 25. Even if two ridges 30 are provided in place of b, and one groove 33a is provided in the contact portion 29 of the main cover 21 in place of the ridge 30, the same effect can be obtained.
In this embodiment, the sliding portion 32 is provided with two grooves 33a and 33b. However, the present invention is not limited to this. For example, if a groove is provided between the two grooves 33a and 33b, the sub-cover 20 can be held at a plurality of angles (multistage) between the grooves. Similarly, by providing a plurality of protrusions 30, the sub-cover 20 can be held at a plurality of angles.

この実施例１は、メインカバー２０よりも工事部５が突出した場合に、本願の取り付け構造を適用したものである。   In the first embodiment, when the construction portion 5 protrudes from the main cover 20, the mounting structure of the present application is applied.

図７に示すように、このサブカバー２０は、開放部２３の両端の隙間２４、すなわち、シャーシ２２とメインカバー２１との間にフック状のアーム２５を挿入して取り付ける構造である。そのため、図７のように、工事部５が突出した場合でも取り付けられる。
このように、工事部５の有無に係わらず。サブカバー２０を取り付けることができる。 As shown in FIG. 7, the sub-cover 20 has a structure in which a hook-like arm 25 is inserted and attached between the gap 24 at both ends of the opening 23, that is, between the chassis 22 and the main cover 21. Therefore, it is attached even when the construction part 5 protrudes as shown in FIG.
Thus, regardless of the presence or absence of the construction section 5. The sub cover 20 can be attached.
