締結している。In the conventional CRT mounting structure, as shown in FIG. 4 (b), the bolt 12 is inserted into the through hole 11B so as not to rotate in advance in the bracket 11 configured as described above. Then, as shown in FIG. 5, screws (or tapping screws) 14 inserted into the through holes 11A are screwed into the housing 13 at the four corners near the opening 13A of the housing 13 to attach the bracket 11. The bolt 12 is inserted into the through hole 15B of the mounting portion 15A of the CRT 15, and the nut 16 is screwed onto the bolt 12 to fasten the CRT 15 to the housing 13.

取り付け直さなければならないという問題点がある。However, when the impact value is large, the process proceeds from the first stage to the second stage, and at this second stage, the bracket 11 and
Bracket 11 to absorb shock at the fastening part of CRT15
A deviation in the direction of arrow A occurred at the fastening part between CRT15 and CRT15
The state shown in FIG. At this time, the upper bracket 11
Between the CRT15 and CRT15 and the lower bracket 11 and CRT
The difference between the fastening parts of 15 is different, and in the normal case, the upper and lower brackets where the CRT15 is fastened after the impact is applied more than the distance between the upper and lower brackets 11 which fastened the CRT15 before the impact is applied. Since the space between 11 is shortened, the upper and lower brackets 11 exert a force that shrinks the casing 13 inward, so that a gap is generated between the casing 13 and the CRT 15, which spoils the aesthetics and occurs. If the gap is large, there is a problem that the CRT15 must be reattached.
この発明は、上記したような問題点を緩和するために

成し、このブラケットを介してCRTを筐体の所定の位置
に取り付けたものである。The mounting structure of the CRT of the present invention comprises a base portion for fastening the bracket to the housing, a boss portion that can be bent while the CRT is attached, and a stopper portion where the bent boss portion abuts, The CRT is attached to the housing at a predetermined position via this bracket.
本発明のCRTの取付構造は、CRTを筐体に取り付けるブ
ラケットをベース部と、ボス部と、ストッパ部で構成し
たので、落下等の衝撃が加わった場合、衝撃の小さいと
きは、ボス部が撓むことによって衝撃が吸収できる。Since the mounting structure of the CRT of the present invention comprises the bracket for mounting the CRT on the housing, the base portion, the boss portion, and the stopper portion, when the impact such as a drop is applied and the impact is small, the boss portion is By bending, the shock can be absorbed.
また、衝撃の大きいときは、上側のボス部とCRTの締

ことができるように直立させて設けられている。The boss portion 3 is provided with a through hole 3A through which a bolt for attaching a CRT is inserted, and is provided upright so that it can be slightly bent with respect to the base portion 2.
ストッパ部4は前記ベース部2のCRT側に設けられ、
ボス部3が撓んだときに衝合するものである。The stopper portion 4 is provided on the CRT side of the base portion 2,
When the boss portion 3 bends, it abuts.

り付ける。The CRT mounting structure according to the present invention includes a bracket 1 configured as described above, a bolt 1 as shown in FIG.
With the 12 inserted into the through hole 2A of the base portion 2 so as not to rotate, the screws 14 are provided at the four corners near the opening 13A of the housing 13 at predetermined intervals L1 as will be described later, as in the conventional case. Install.
そして、CRT15の取付部15Aの貫通孔15Bにボルト12を
挿通させ、ナット16をボルト12に螺合させてCRT15を筐
体13に第2図のように締結する。Then, the bolt 12 is inserted into the through hole 15B of the mounting portion 15A of the CRT 15, the nut 16 is screwed onto the bolt 12, and the CRT 15 is fastened to the housing 13 as shown in FIG.
次に、第3図(a)〜(d)でテレビ受像機が落下等
によって衝撃を受けた状態を段階的に説明する。Next, a state in which the television receiver is impacted by being dropped or the like will be described step by step in FIGS. 3 (a) to 3 (d).
まず、第3図(a)のようにCRT15と、ブラケット1

ボス部3がストッパ部4に衝合することなく撓むことに
よって衝撃が緩和され、ボルトで締結されているCRT15

用する剪断力は小さくなり、ボス部3とCRT15の取付部1
5Aの間でずれは発生せず、上側のボス部3はストッパ部
4にも衝合していない状態となっている。First, as shown in Fig. 3 (a), CRT15 and bracket 1
When the TV receiver falls on the floor etc. with the CRT attached so that the space (gap) on the side of the is L1, the CRT15 collides with the lower base part 2 in the first stage where the impact value is small. It falls down as shown in FIG. 3 (b) until just before, but at this stage, the boss 3 bends without hitting the stopper 4 due to the gap L2 between the upper boss 3 and the stopper 4, and the impact is generated. Is relaxed and bolted CRT15
The shearing force acting on the fastening portion between the mounting portion 15A for mounting and the boss portion 3 becomes small, and the mounting portion 1 of the boss portion 3 and the CRT 15
No deviation occurs between 5A, and the upper boss portion 3 is in a state of not hitting the stopper portion 4 either.
この状態から衝撃値が増加する第2段階では、下側の
ブラケットのベース部2が下方に押される状態となるた

み、又、このときに下側のブラケット1と筐体13の間に
僅かな剪断力が作用するが、いずれにしてもCRT15がさ
らに下方へ移動しようとすると上側のボス部3がストッ
パ部4に衝合し、衝撃を上側のストッパ部が負担して第
3図(c)のような状態となる。In the second stage where the impact value increases from this state, the base portion 2 of the lower bracket is pushed downward, so that the lower side of the housing 13 flexes slightly to absorb the impact, and A slight shearing force sometimes acts between the lower bracket 1 and the housing 13, but in any case, when the CRT 15 tries to move further downward, the upper boss portion 3 collides with the stopper portion 4, The upper stopper portion bears the impact, resulting in the state as shown in FIG. 3 (c).
そして、この段階で瞬間的な応力を受けた下側のブラ
ケット1は元の位置に復帰することが可能である。Then, at this stage, the lower bracket 1 that receives an instantaneous stress can return to its original position.
さらに、衝撃値が最大となる第3段階では、下側のブ

13と下側のブラケット1に歪みが生じると共に、上側の
ボス部3とCRT15の締結部分にも矢印方向Bのずれが発
生する。Further, in the third stage where the impact value is maximum, the impact on the lower bracket 1 is further increased, so that
13 and the lower bracket 1 are distorted, and the upper boss portion 3 and the fastening portion of the CRT 15 are also displaced in the arrow direction B.
しかし、CRTの下側は、下側のブラケットのベース部
2で支えられているため、この段階での衝撃が与える剪
断力は、主に上側のブラケットのボス部3の締結部に作
用し、この上側の締結部のずれの方が下側の締結部のず
れより大きくなる。However, since the lower side of the CRT is supported by the base portion 2 of the lower bracket, the shearing force given by the impact at this stage mainly acts on the fastening portion of the boss portion 3 of the upper bracket, The displacement of the upper fastening portion is larger than the displacement of the lower fastening portion.
そのため、衝撃が加わる前にCRT15を締結した上側,
下側のブラケット1の間隔よりも、衝撃が加わった後に
復帰した上側,下側のブラケット1の締結間隔の方が長
くなる。Therefore, the upper side where CRT15 is fastened before impact is applied,
The fastening distance between the upper and lower brackets 1 that have been restored after the impact is applied is longer than the distance between the lower brackets 1.
衝撃が取り除かれる第4段階では、上、下側のブラケ
ット1と筐体13の間に発生した瞬間的なずれがほぼ復元
されるため、上、下側のブラケット1は第3図(a)の
状態に近い状態に復帰するが、前述したようにCRT15を

くなる。At the fourth stage where the impact is removed, the instantaneous displacement generated between the upper and lower brackets 1 and the housing 13 is almost restored, so that the upper and lower brackets 1 are shown in FIG. 3 (a). Although it returns to a state close to the above state, since the interval between the upper and lower brackets 1 to which the CRT15 is fixed is longer than the initial state as described above, the upper and lower brackets 1
Exerts a force that spreads the housing 13 outward, and as a result, the contact portion (the bezel) between the housing 13 and the CRT has a shape in which the housing 13 and the CRT are folded inward, and between the housing 13 and the CRT 15. No gaps will occur.

収できる。[Effects of the Invention] As described above, the CRT mounting structure of the present invention is
It is composed of a base part that fastens the bracket to the housing, a boss part that can bend when an impact is applied, and a stopper part that the boss part abuts. Since the CRT is fixed to the housing by attaching the bracket to the housing so that it is almost the same as the side surface or slightly larger than the side surface, if the impact such as a drop is applied and the impact is small, the boss should be The shock can be absorbed by the bending of the portion.

体とCRTの間に隙間が発生することを緩和することがで
きるいう利点がある。Also, when the impact is large, first, the base part collides with the CRT to prevent the CRT from moving, and if further impact is applied from this point, the mounting interval is mainly at one boss part and the fastening part of the CRT. There is an advantage that it is possible to mitigate the occurrence of a gap between the housing and the CRT after the restoration because the deviation that spreads occurs.
