Description

本発明は、テレビジョン受像機の合成樹脂製キャビネット、特にＣＲＴ（ブラウン管）の表示面を前方へ向けて露出させる略矩形の開口の周囲の荷重集中による白化現象を防ぐ対策を講じたものに関する。   The present invention relates to a synthetic resin cabinet of a television receiver, and more particularly to a measure that prevents whitening due to load concentration around a substantially rectangular opening that exposes the display surface of a CRT (CRT) forward.

図３にテレビジョン受像機の合成樹脂製キャビネットの従来例の要部を示してある。このキャビネットは、フロント部材１と図示していないリヤ部材とに分割されていて、フロント部材１とリヤ部材とを結合することによって構成されるようになっている。そして、フロント部材１は、略矩形の開口１１を備えた前枠部１２とこの前枠部１２の外周部から後方へ張り出した外枠部１３とを備えていて、前枠部１２の裏面には、開口１１の口縁全域に亘る背低リブでなる縁枠部１４が備わっている。また、開口１１のコーナ部１１ａの近傍箇所に位置する背高ボス１５が備わっていて、この背高ボス１５を挟む両側にポスト１６が備わっている。そして、背高ボス１５と外枠部１３との間、並びに、背高ボス１５とそれぞれのポスト１６，１６との間に板片状のリブ１７，１８が配備されている。   FIG. 3 shows a main part of a conventional example of a synthetic resin cabinet of a television receiver. The cabinet is divided into a front member 1 and a rear member (not shown), and is configured by joining the front member 1 and the rear member. The front member 1 includes a front frame portion 12 having a substantially rectangular opening 11 and an outer frame portion 13 projecting rearward from the outer peripheral portion of the front frame portion 12. Is provided with an edge frame portion 14 formed of a low-profile rib over the entire mouth edge of the opening 11. Moreover, the tall boss | hub 15 located in the location near the corner part 11a of the opening 11 is provided, and the post | mailbox 16 is provided in the both sides on which this tall boss | hub 15 is pinched | interposed. Plate-shaped ribs 17 and 18 are provided between the tall boss 15 and the outer frame portion 13 and between the tall boss 15 and the respective posts 16 and 16.

このキャビネットでは、ＣＲＴの外周囲が縁枠部１４に重ね合わされてそのＣＲＴの表示面が開口１１からその前方へ向けて露出されると共に、ＣＲＴが止具を介して背高ボス１５によって支持される。   In this cabinet, the outer periphery of the CRT is superimposed on the edge frame portion 14 so that the display surface of the CRT is exposed forward from the opening 11 and the CRT is supported by the tall boss 15 via a stopper. The

一方、従来より、画像表示装置において、ＣＲＴを外部に臨ませる開口の周囲部に設けたリブにＣＲＴを接触させるようにすると共に、そのリブの角部の肉厚を減少させることによってＣＲＴとの接触面積を狭くし、そうすることによってリブの角部の割れを防ぐようにすることも提案されている（たとえば、特許文献１参照）。また、電気機器のキャビネットにおいて、フロントキャビネットとリヤキャビネットとの合わせ箇所において、リヤキャビネットに設けられているリブのコーナ部を欠除することによって、そのリブのコーナ部が落下荷重を受けて割れたりすることを防ぐ技術が知られている（たとえば、特許文献２参照）。
特開２００３−３２５７６号公報 特開平１１−２１５４４９号公報 On the other hand, conventionally, in an image display device, the CRT is brought into contact with a rib provided around the opening that faces the CRT to the outside, and the thickness of the corner of the rib is reduced to reduce the thickness of the CRT. It has also been proposed to reduce the contact area and thereby prevent cracks at the corners of the rib (see, for example, Patent Document 1). Also, in electrical equipment cabinets, the corners of the ribs provided in the rear cabinet are removed at the joints between the front cabinet and the rear cabinet, so that the corners of the ribs can be broken by receiving a drop load. A technique for preventing this is known (see, for example, Patent Document 2).
JP 2003-32576 A JP 11-215449 A

図３で説明した従来のキャビネットでは、背高ボス１５が前枠部１２の４隅にそれぞれ設けられていて、それらの背高ボス１５により取付けねじを介してＣＲＴが支持される。そして、それぞれの背高ボス１５が開口１１の４隅のそれぞれの近傍箇所に設置されていることなどにより、背高ボス１５によって支持させたＣＲＴの重量による荷重が、開口１１のコーナ部１１ａに集中する傾向があり、そのような集中荷重を受けて縁枠部１４のコーナ部１４ａの周囲の一定領域内に、そのコーナ部１４ａを起点として放射方向に延びる白化ライン（白化の筋）Ａが発生することがある。１９インチよりも小さいサイズのＣＲＴを用いるテレビジョン受像機ではＣＲＴが比較的軽量であったことなどのため、上記のような白化ラインＡが目立って生じるという事態は発生せず、また、塗装によって白化が目立たなかったということもあって、そのような白化ラインＡの発生を防ぐ対策を講じることは特に必要とされなかった。   In the conventional cabinet described with reference to FIG. 3, the tall bosses 15 are provided at the four corners of the front frame portion 12, and the CRT is supported by the tall bosses 15 via attachment screws. And the load by the weight of CRT supported by the tall boss | hub 15 by each tall boss | hub 15 being installed in each vicinity of each of the four corners of the opening 11 is applied to the corner part 11a of the opening 11. A whitening line (whitening streaks) A extending in the radial direction from the corner portion 14a as a starting point is formed in a certain area around the corner portion 14a of the edge frame portion 14 in response to such a concentrated load. May occur. In a television receiver using a CRT having a size smaller than 19 inches, the whitening line A as described above does not occur conspicuously because the CRT is relatively light. Since whitening was not conspicuous, it was not particularly necessary to take measures to prevent such whitening line A from occurring.

しかしながら、近時のようにＣＲＴの大型化や平面化に伴ってＣＲＴの重量が重くなってくると、図３で説明した従来の構造では、そのＣＲＴの重さに耐えきれなくなって縁枠部１４のコーナ部１４ａの周囲に生じる上記したような白化ラインＡが目立つようになるおそれが生じた。   However, if the weight of the CRT becomes heavier as the size of the CRT becomes larger and flatter as in recent times, the conventional structure described in FIG. 3 cannot withstand the weight of the CRT and the edge frame portion. The above-described whitening line A generated around the 14 corner portions 14a may become noticeable.

これに対し、特許文献１によって開示された技術は、ＣＲＴが重ね合わされるリブの角部の肉厚を減少させてリブとＣＲＴとの接触面積を狭くするというものであるので、リブによる開口のコーナ部の補強強度が低下するおそれがある。また、特許文献２によって開示された技術は、フロントキャビネットとリヤキャビネットとの合わせ箇所での割れを防ぐ技術であるので、図３で説明した縁枠部１４の周囲に白化ラインＡが生じることを回避することとは関係がない。   On the other hand, the technique disclosed in Patent Document 1 is to reduce the thickness of the corners of the ribs on which the CRTs are overlapped to narrow the contact area between the ribs and the CRT. There is a possibility that the reinforcing strength of the corner portion is lowered. Moreover, since the technique disclosed by patent document 2 is a technique which prevents the crack in the joining location of a front cabinet and a rear cabinet, whitening line A arises around the edge frame part 14 demonstrated in FIG. It has nothing to do with avoidance.

本発明は以上の状況の下でなされたものであり、背高ボスで支えるＣＲＴの重量が重くなっても、そのＣＲＴの重量による荷重で縁枠部のコーナ部の周囲に白化ラインが発生することを防ぐことのできるテレビジョン受像機の合成樹脂製キャビネットを提供することを目的とする。   The present invention has been made under the above circumstances, and even when the weight of the CRT supported by the tall boss increases, a whitening line is generated around the corner portion of the edge frame portion by the load due to the weight of the CRT. It is an object of the present invention to provide a synthetic resin cabinet for a television receiver that can prevent this.

また、本発明は、従来のキャビネットを成形するための金型の成形面を形状変更するだけで成形することができるにもかかわらず、ＣＲＴの重量による荷重で縁枠部のコーナ部の周囲に白化ラインが発生することを防ぐことのできるテレビジョン受像機の合成樹脂製キャビネットを提供することを目的とする。   In addition, although the present invention can be molded by simply changing the shape of the mold for molding a conventional cabinet, it is placed around the corner portion of the edge frame by the load due to the weight of the CRT. An object of the present invention is to provide a synthetic resin cabinet for a television receiver capable of preventing the generation of a whitening line.

本発明に係るテレビジョン受像機の合成樹脂製キャビネットは、ＣＲＴの表示面を前方へ向けて露出させる略矩形の開口を備えた前枠部の裏面に、上記開口の口縁全域に亘り上記ＣＲＴが重ね合わされる背低リブでなる縁枠部が備わっていると共に、上記開口のコーナ部の近傍箇所に位置して、上記ＣＲＴを止具を介して支持する背高ボスが備わっている。そして、上記背高ボスに支持させたＣＲＴの重量による荷重が集中する上記縁枠部のコーナ部に始端が位置しかつ上記背高ボスに終端が連結された直線状の補強リブを、上記前枠部と一体にその裏面に形成することによって、上記開口のコーナ部の近傍箇所が白化することを防いでいる、というものである。   The synthetic resin cabinet of the television receiver according to the present invention includes the CRT over the entire edge of the opening on the back surface of the front frame portion having a substantially rectangular opening that exposes the display surface of the CRT forward. And a tall boss for supporting the CRT via a stopper located in the vicinity of the corner of the opening. A straight reinforcing rib having a start end located at a corner portion of the edge frame portion where a load due to the weight of the CRT supported by the tall boss is concentrated and a terminal end connected to the tall boss is connected to the front boss. By forming on the back surface integrally with the frame portion, whitening of the vicinity of the corner portion of the opening is prevented.

この構成であれば、背高ボスに支持させたＣＲＴの重量による荷重が、縁枠部のコーナ部に始端が位置しかつ背高ボスに終端が連結された直線状の補強リブによって主に受け止められるようになる。そのために、縁枠部のコーナ部の周囲に白化ラインが生じるほどの荷重が加わらなくなって白化ラインの発生が防止される。また、上記補強リブは、落下衝撃による縁枠部のコーナ部に割れや亀裂が入ることをも防ぐ作用を発揮する。   With this configuration, the load due to the weight of the CRT supported by the tall boss is mainly received by the linear reinforcing rib whose start end is located at the corner of the edge frame and whose end is connected to the tall boss. Be able to. For this reason, a load enough to generate a whitening line around the corner portion of the edge frame is not applied, and the generation of the whitening line is prevented. Further, the reinforcing rib exhibits an effect of preventing the corner portion of the edge frame portion from being cracked or cracked due to a drop impact.

本発明では、上記補強リブの始端と同一位置に始端を有して互いに直交する方向に直線状に延び出ることによってその補強リブを挟む両側に各別に位置する一対の補助リブが、上記前枠部と一体にその裏面に形成されていることが望ましい。これによれば、補強リブだけでなく、その補強リブの両側の一対の補助リブもＣＲＴの重量による荷重を受け止めることに役立つ。また、補強リブと一対の補強リブとが、縁枠部のコーナ部を起点として、そのコーナ部の周囲に生じると予測される白化ラインＡ（図３参照）に沿う方向に延びた形状になるために、白化ラインの発生がいっそう確実に防止されるようになる。   In the present invention, a pair of auxiliary ribs that have a starting end at the same position as the starting end of the reinforcing rib and extend linearly in a direction orthogonal to each other, and are respectively positioned on both sides sandwiching the reinforcing rib are the front frame. It is desirable that it is formed on the back surface integrally with the portion. According to this, not only the reinforcing rib but also a pair of auxiliary ribs on both sides of the reinforcing rib is useful for receiving the load due to the weight of the CRT. Further, the reinforcing rib and the pair of reinforcing ribs have a shape extending from the corner portion of the edge frame portion in the direction along the whitening line A (see FIG. 3) that is predicted to be generated around the corner portion. Therefore, the generation of whitening lines can be prevented more reliably.

本発明では、上記補強リブ及び一対の上記補助リブが、上記縁枠部を形成している背低リブよりも背低に形成されていることが望ましい。これによれば、縁枠部のＣＲＴを重ね合わせた場合に、補強リブや補助リブがＣＲＴと接触しなくなる。そのために、ＣＲＴの重量が補強リブや補助リブに直接加わることがなくなり、補強リブや補助リブによる白化ラインの発生を防ぐ作用が確実に発揮されるようになる。   In the present invention, it is desirable that the reinforcing rib and the pair of auxiliary ribs are formed to be shorter than the low ribs forming the edge frame portion. According to this, when the CRT of the edge frame portion is overlapped, the reinforcing rib and the auxiliary rib do not come into contact with the CRT. For this reason, the weight of the CRT is not directly applied to the reinforcing ribs and auxiliary ribs, and the effect of preventing the whitening line from being generated by the reinforcing ribs and auxiliary ribs is reliably exhibited.

本発明では、一対の上記補助リブのうちの片側の補助リブの終端が上記背高ボスを挟む両側に各別に位置する一対のポストのうちの片側のポストに連結され、他側の補助リブの終端が他側のポストに連結されていることが望ましい。これによれば、一対の補助リブによる補強作用によって、縁枠部のコーナ部と片側及び他側の各ポストとの間の箇所の歪み変形が防止されて白化の発生が防止される。   In the present invention, the terminal end of one side of the pair of auxiliary ribs is connected to one side of the pair of posts located separately on both sides of the tall boss, and the other side of the auxiliary ribs It is desirable that the end is connected to the post on the other side. According to this, due to the reinforcing action by the pair of auxiliary ribs, distortion deformation of a portion between the corner portion of the edge frame portion and each post on one side and the other side is prevented, and the occurrence of whitening is prevented.

本発明では、上記前枠部にその外周部から後方へ張り出した外枠部が備わり、その外枠部と上記背高ボスとの間に亘って一体成形された板片状のリブが配備されていると共に、上記背高ボスと一対のポストとの間に亘って一体成形された板片状のリブが配備されていることが望ましい。これによれば、背高ボスと外枠部との間の箇所の歪み変形が防止され、そのことが、縁枠部のコーナ部の周囲に白化ラインが生じることを防ぐことに役立つ。   In the present invention, the front frame portion is provided with an outer frame portion projecting rearward from the outer peripheral portion thereof, and a plate-like rib integrally formed between the outer frame portion and the tall boss is provided. In addition, it is desirable that a plate-like rib integrally formed between the tall boss and the pair of posts is provided. According to this, distortion deformation of the location between the tall boss and the outer frame portion is prevented, which helps to prevent whitening lines from occurring around the corner portion of the edge frame portion.

本発明に係るテレビジョン受像機の合成樹脂製キャビネットは、次の構成を採用することよっていっそう具体化される。すなわち、ＣＲＴの表示面を前方へ向けて露出させる略矩形の開口を備えた前枠部の裏面に、上記開口の口縁全域に亘り上記ＣＲＴが重ね合わされる背低リブでなる縁枠部が備わっていると共に、上記開口のコーナ部の近傍箇所に位置して、上記ＣＲＴを止具を介して支持する背高ボスが備わっているテレビジョン受像機の合成樹脂製キャビネットにおいて、上記前枠部とその外周部から後方へ張り出した外枠部とを備えるフロント部材と、そのフロント部材に結合されるリヤ部材とでなり、上記背高ボスに支持させたＣＲＴの重量による荷重が集中する上記縁枠部のコーナ部に始端が連結されかつ上記背高ボスに終端が連結された直線状の補強リブと、この補強リブの始端と同一位置に始端を有して互いに直交する方向に直線状に延び出ることによってその補強リブを挟む両側に各別に位置する一対の補助リブとが、上記前枠部と一体にその裏面に形成されていると共に、上記補強リブ及び一対の上記補助リブが、上記縁枠部を形成している背低リブよりも背低に形成され、一対の上記補助リブのうちの片側の補助リブの終端が上記背高ボスを挟む両側に各別に位置する一対のポストのうちの片側のポストに連結され、他側の補助リブの終端が他側のポストに連結され、上記外枠部と上記背高ボスとの間に亘って一体成形された板片状のリブと、上記背高ボスと一対のポストとの間に亘って一体成形された板片状のリブとを備えている、という構成を採用することによっていっそう具体化される。この発明の作用については、後述する実施形態を参照して詳細に説明する。   The synthetic resin cabinet of the television receiver according to the present invention is further embodied by adopting the following configuration. That is, an edge frame portion formed of a low rib on which the CRT is overlapped over the entire rim of the opening on the back surface of the front frame portion having a substantially rectangular opening that exposes the display surface of the CRT forward. In the synthetic resin cabinet of a television receiver provided with a tall boss that is provided near the corner portion of the opening and supports the CRT via a stopper. And an outer frame portion projecting rearward from the outer peripheral portion thereof, and a rear member coupled to the front member, and the edge on which the load due to the weight of the CRT supported by the tall boss is concentrated A linear reinforcing rib whose starting end is connected to the corner of the frame and whose end is connected to the tall boss, and has a starting end at the same position as the starting end of the reinforcing rib, and is linear in a direction perpendicular to each other. Extend And a pair of auxiliary ribs that are separately located on both sides of the reinforcing rib and formed on the back surface thereof integrally with the front frame portion, and the reinforcing rib and the pair of auxiliary ribs are formed on the edge frame. Of the pair of posts, the end of one side of the pair of auxiliary ribs is positioned separately on both sides of the tall boss. A plate-like rib connected to the post on one side, the terminal of the auxiliary rib on the other side connected to the post on the other side, and integrally formed between the outer frame portion and the tall boss; The present invention is further embodied by adopting a configuration in which a plate-like rib integrally formed between the tall boss and the pair of posts is provided. The effect | action of this invention is demonstrated in detail with reference to embodiment mentioned later.

以上のように、本発明によれば、ＣＲＴの重量が重いことに起因する縁枠部のコーナ部の周囲の白化を防ぐために、縁枠部とコーナ部の位置とＣＲＴを支える背高ボスの位置との関係を考慮して補強リブ又は補助リブを設けてあり、しかも、縁枠部のコーナ部の肉厚を減じるものではないので、縁枠部による開口のコーナ部の補強作用を損なうことなく、縁枠部のコーナ部の周囲に白化ラインが発生することを防ぐことが可能になる。また、落下衝撃による縁枠部のコーナ部に割れや亀裂が入ることも防止される。したがって、白化によってキャビネットの耐用寿命が損なわれたりその見栄えが悪くなったりするという事態が起こりにくくなる。   As described above, according to the present invention, in order to prevent whitening around the corner portion of the edge frame portion due to the heavy weight of the CRT, the position of the edge frame portion and the corner portion, and the height of the tall boss that supports the CRT Reinforcing ribs or auxiliary ribs are provided in consideration of the relationship with the position, and since the thickness of the corner portion of the edge frame portion is not reduced, the reinforcing action of the corner portion of the opening by the edge frame portion is impaired. Therefore, it is possible to prevent whitening lines from occurring around the corner portion of the edge frame portion. In addition, it is possible to prevent the corner portion of the edge frame portion from being cracked or cracked due to a drop impact. Therefore, it is difficult to cause a situation in which the useful life of the cabinet is impaired or its appearance is deteriorated due to whitening.

また、本発明に係るキャビネットは、従来のキャビネットを成形するための金型の成形面を少しだけ形状変更するだけで成形することができるという利点がある。   In addition, the cabinet according to the present invention has an advantage that it can be molded by slightly changing the shape of the molding surface of a mold for molding a conventional cabinet.

図１は本発明に係るテレビジョン受像機の合成樹脂製キャビネットを概略で示した背面図、図２（Ａ）は図１のキャビネットの要部を拡大した背面図、同（Ｂ）は同（Ａ）のＩＩＢ−ＩＩＢ線に沿う部分の拡大断面図である。   FIG. 1 is a rear view schematically showing a synthetic resin cabinet of a television receiver according to the present invention, FIG. 2A is an enlarged rear view of the main part of the cabinet of FIG. 1, and FIG. It is an expanded sectional view of the part which follows the IIB-IIB line of A).

図１に示したキャビネットは、フロント部材１と図示していないリヤ部材とに分割されていて、フロント部材１とリヤ部材とを結合することによって構成される。フロント部材１は、略矩形の開口１１を備えた前枠部１２とこの前枠部１２の外周部から後方へ張り出した外枠部１３とを備えていて、前枠部１２の裏面に、開口１１の口縁全域に亘る背低リブでなる縁枠部１４が備わっていると共に、開口１１のコーナ部１１ａの近傍箇所に背高ボス１５が備わっていて、この背高ボス１５を挟む両側にポスト１６が備わっている。そして、図２のように、背高ボス１５と外枠部１３との間、並びに、背高ボス１５とそれぞれのポスト１６，１６との間に板片状のリブ１７，１８が配備されている。このキャビネットでは、ＣＲＴ（不図示）の外周囲が縁枠部１４に重ね合わされてそのＣＲＴの表示面が開口１１からその前方へ向けて露出されると共に、ＣＲＴが取付けねじでなる止具（不図示）を介して背高ボス１５によって支持される。このキャビネットの構成は以上の点で図２で説明したキャビネットの構成と相応していて、背高ボス１５が、ポスト１６、板片状のリブ１７，１８、外枠部１３などによって補強されている。また、ＣＲＴの重量による荷重が、縁枠部１４のコーナ部１４ａの近傍箇所に集中する傾向がある。そのため、大型のＣＲＴや平面ＣＲＴのように重量の重いＣＲＴが取り付けられた場合には、図３を参照して冒頭で説明したように縁枠部１４のコーナ部１４ａを起点として放射方向に延びる白化ライン（白化の筋）Ａが発生することがあった。   The cabinet shown in FIG. 1 is divided into a front member 1 and a rear member (not shown), and is configured by connecting the front member 1 and the rear member. The front member 1 includes a front frame portion 12 having a substantially rectangular opening 11 and an outer frame portion 13 projecting rearward from the outer peripheral portion of the front frame portion 12. 11 is provided with an edge frame portion 14 formed of a low-profile rib over the entire area of the mouth edge, and a tall boss 15 is provided in the vicinity of the corner portion 11a of the opening 11 on both sides sandwiching the tall boss 15. A post 16 is provided. As shown in FIG. 2, plate-like ribs 17 and 18 are provided between the tall boss 15 and the outer frame portion 13 and between the tall boss 15 and the respective posts 16 and 16. Yes. In this cabinet, the outer periphery of a CRT (not shown) is superimposed on the edge frame portion 14 so that the display surface of the CRT is exposed from the opening 11 to the front thereof, and the CRT is a fastener (not shown) that is a mounting screw. It is supported by the tall boss 15 through the figure. The configuration of this cabinet corresponds to the configuration of the cabinet described in FIG. 2 in the above points, and the tall boss 15 is reinforced by the post 16, plate-like ribs 17 and 18, the outer frame portion 13, and the like. Yes. In addition, the load due to the weight of the CRT tends to concentrate in the vicinity of the corner portion 14 a of the edge frame portion 14. Therefore, when a heavy CRT such as a large CRT or a flat CRT is attached, it extends in the radial direction starting from the corner portion 14a of the edge frame portion 14 as described above with reference to FIG. A whitening line (whitening line) A sometimes occurred.

そこで、この実施形態では、図２（Ａ）（Ｂ）に示したように、縁枠部１４のコーナ部１４ａに始端２１を有する単一条の直線状の補強リブ２と、この補強リブ２の始端２１と同一位置に始端３１を有する２条の直線状の補助リブ３とを、前板部１２の裏面に一体成形してある。このうち、単一条の直線状の補強リブ２は、ＣＲＴの重量による荷重が集中して白化ラインＡ（図３参照）が発生するであろうと予測される領域の中央部を、発生が予想される白化ラインＡに沿って延びていて、その終端２２が背高ボス１５の基部に連結されて一体化されている。これに対し、２条の直線状の補助リブ３，３はそれらの始端３１，３１から互いに直交する方向に延び出ることによって、上記補強リブ２を挟む両側に各別に位置しており、しかも、ＣＲＴの重量による荷重が集中して白化ラインＡ（図３参照）が発生するであろうと予測される領域の外側に位置している。そして、それらの片側の補助リブ３の終端３２が背高ポスト１５の片側に位置しているポスト１６に連結されて一体化され、かつ、他側の補助リブ３の終端３２が背高ポスト１５の他側に位置しているポスト１６に連結されて一体化されている。したがって、これらの補助リブ３，３も、発生が予想される白化ラインＡに沿って延びている。   Therefore, in this embodiment, as shown in FIGS. 2 (A) and 2 (B), a single-line linear reinforcing rib 2 having a start end 21 at a corner portion 14a of the edge frame portion 14, and the reinforcing rib 2 Two linear auxiliary ribs 3 having a start end 31 at the same position as the start end 21 are integrally formed on the back surface of the front plate portion 12. Among these, the single-line linear reinforcing rib 2 is expected to be generated in the central portion of the region where the whitening line A (see FIG. 3) is expected to be concentrated due to the concentrated load due to the weight of the CRT. It extends along the whitening line A, and its end 22 is connected to and integrated with the base of the tall boss 15. On the other hand, the two linear auxiliary ribs 3 and 3 are located on both sides sandwiching the reinforcing rib 2 by extending from their starting ends 31 and 31 in directions orthogonal to each other, It is located outside the region where the load due to the weight of the CRT is concentrated and the whitening line A (see FIG. 3) is expected to occur. The end 32 of the auxiliary rib 3 on one side is connected to and integrated with the post 16 positioned on one side of the tall post 15, and the end 32 of the auxiliary rib 3 on the other side is integrated with the tall post 15. It is connected and integrated with a post 16 located on the other side. Therefore, these auxiliary ribs 3 and 3 also extend along the whitening line A that is expected to occur.

このような形態で上記補強リブ２が設けられていると、背高ボス１５に支持させたＣＲＴの重量による荷重が補強リブ２によって主に受け止められるようになるため、縁枠部１４のコーナ部１４ａの周囲に図３で説明したような白化ラインＡが生じるほどの荷重が加わらなくなって白化ラインの発生が防止された。しかも、この補強リブ２の補強作用によって、落下衝撃による縁枠部１４のコーナ部１４ａに割れや亀裂が入ることも防ぐことができた。さらに、補強リブ２を挟む両側に各別に位置する一対の補助リブ３，３がＣＲＴの重量による荷重を受け止めることに役立ち、しかも、補強リブ２と一対の補強リブ３，３とが、縁枠部１４のコーナ部１４ａの周囲に生じると予測される白化ラインＡ（図３参照）に沿う方向に延びていることによって、白化ラインの発生がいっそう確実に防止されるようになった。   When the reinforcing rib 2 is provided in such a form, a load due to the weight of the CRT supported by the tall boss 15 is mainly received by the reinforcing rib 2. As a result, a load sufficient to generate the whitening line A described with reference to FIG. In addition, the reinforcing action of the reinforcing rib 2 can prevent the corner portion 14a of the edge frame portion 14 from being dropped or cracked due to a drop impact. Furthermore, the pair of auxiliary ribs 3 and 3 that are separately located on both sides of the reinforcing rib 2 help to receive the load due to the weight of the CRT, and the reinforcing rib 2 and the pair of reinforcing ribs 3 and 3 By extending in the direction along the whitening line A (see FIG. 3) that is expected to occur around the corner portion 14a of the portion 14, the generation of the whitening line is more reliably prevented.

この実施形態では、補強リブ２及び一対の補助リブ３，３を、縁枠部１４を形成している背低リブよりも少し背低に形成してある。具体的には、縁枠部１４を形成している背低リブの高さが１〜２ｍｍに定められ、補強リブ２及び一対の補助リブ３，３の高さがねれよりも小さい寸法に定められている。そのため、縁枠部１４にＣＲＴを重ね合わせた場合には、図２（Ｂ）に示されている片側の補助リブ３だけでなく、他側の補助リブ３や補強リブ２がＣＲＴに対して間隔を隔てて位置することになり、同図に示したようにＣＲＴ１００が補強リブ２や補助リブ３，３に接触することがなく、その結果、ＣＲＴ１００の重量が補強リブ２や補助リブ３，３に直接加わることがなくなって補強リブ２や補助リブ３，３による白化ラインの発生を防ぐ作用が確実に発揮されるようになる。   In this embodiment, the reinforcing rib 2 and the pair of auxiliary ribs 3 and 3 are formed slightly lower than the low ribs forming the edge frame portion 14. Specifically, the height of the low ribs forming the edge frame portion 14 is determined to be 1 to 2 mm, and the height of the reinforcing rib 2 and the pair of auxiliary ribs 3 and 3 is smaller than the thread. It has been established. Therefore, when the CRT is overlaid on the edge frame portion 14, not only the auxiliary rib 3 on one side shown in FIG. As shown in the figure, the CRT 100 does not come into contact with the reinforcing rib 2 and the auxiliary ribs 3 and 3, so that the weight of the CRT 100 is increased. 3 is no longer directly applied, and the effect of preventing the whitening line from being generated by the reinforcing ribs 2 and the auxiliary ribs 3 and 3 is reliably exhibited.

さらに、この実施形態では、補強リブ２や補助リブ３，３が、縁枠部１４のコーナ部１４ａと背高ボス１５ないし各ポスト１６，１６との間の箇所の歪み変形を防ぐことにも役立っている。その上、板片状のリブ１７，１８によって背高ボス１５と外枠部１３との間の箇所の歪み変形を防止されるので、そのことが、縁枠部１４のコーナ部１４ａの周囲に白化ラインが生じることを防ぐことに役立っている。   Further, in this embodiment, the reinforcing ribs 2 and the auxiliary ribs 3 and 3 also prevent distortion deformation at a location between the corner portion 14a of the edge frame portion 14 and the tall boss 15 or the posts 16 and 16. Helpful. In addition, since the plate-like ribs 17 and 18 prevent distortion deformation at a location between the tall boss 15 and the outer frame portion 13, this is around the corner portion 14 a of the edge frame portion 14. This helps to prevent whitening lines.

図２では、縁枠部１４の１つのコーナ部１４について説明したけれども、他の３つのコーナ部についても相応の構造が採用されていて、同様の作用が発揮されるようになっている。   Although one corner portion 14 of the edge frame portion 14 has been described with reference to FIG. 2, a corresponding structure is adopted for the other three corner portions so that the same action is exhibited.

上記した補強リブ２や補助リブ３を備えるフロント部材１は、図３で説明したフロント部材１を成形するための成形金型の成形面に、補強リブ２や補助リブ３の成形面を追加するという形状変更を行うだけで製作することができるため、従来のキャビネットを成形するための成形金型の成形面の形状変更を行うだけで当該フロント部材１を容易にかつ安価に成形することができるようになるという利点がある。   The front member 1 including the reinforcing rib 2 and the auxiliary rib 3 described above adds the molding surface of the reinforcing rib 2 and the auxiliary rib 3 to the molding surface of the molding die for molding the front member 1 described in FIG. Therefore, the front member 1 can be easily and inexpensively formed simply by changing the shape of the molding surface of a molding die for forming a conventional cabinet. There is an advantage of becoming.
