【発明が解決しようとする課題】しかし、上記のような従来の構造では、液晶表示装置を分解する必要が生じたとき、例えば修理したいときに、一旦折り曲げたフレームの爪の端部を、逆方向に曲げて、曲げる前の形に戻そうとしても、曲がり目部分の材料が時効硬化などにより硬化してしまっているために、曲げ戻しが困難で、時には、切り込み部から折れて切れてしまい、フレーム全体を取替える必要が生ずるようになることが少なくなかった。 [SUMMARY OF THE INVENTION However, in the conventional structure as described above, when the need to disassemble the liquid crystal display device occurs, for example when it is desired to repair the ends of the claws of the frame folded once, the reverse bent in the direction, even attempting to return to the shape before bending, for the material of the bend portion is accidentally cured by like age hardening, is difficult to bent back, sometimes, it will be fully broken from the cut portion it was not less that become necessary arises to replace the entire frame. また、付属部材の厚さと、フレームの爪に設ける切り込み部の位置の関係が微妙で、切り込み部から上を曲げても、曲げた部分と付属部材背面の間に僅かな隙間が残存してガタつき易いなどの問題もあった。 Further, the thickness of the accessory members, the relationship between the position of the cut portion provided in the nail frame subtle, even when bent over from the cut portion, and a slight gap between the bent portion and accessory members back residual backlash there is also a problem, such as easy month.

【0004】本発明は上記のような問題が生じないようにした、分解時にフレームを損傷することなく容易に分解できる液晶表示装置を提供することを課題とする。 [0004] The present invention was made to the above-described problem does not occur, and to provide a liquid crystal display device can be easily disassembled without damaging the frame during disassembly.

【0005】 [0005]

【課題を解決するための手段】上記課題を解決するために本発明においては、液晶表示素子の背後に配置するプリント基板などの付属部材を、それらの背面周辺で押さえて固定するために、液晶表示素子の画像表示面の周辺を囲むフレームの、付属部材の背面を越えて突出している爪の端部の近くに、それぞれ孔を設け、各孔に、周辺外側から、それぞれ、先細のピンを挿入し、孔を通過したピンの端部側で付属部材の背面を押さえさせて、付属部材を固着させるようにした。 In the present invention in order to solve the above object, according to an aspect of the accessory member, such as a printed circuit board arranged behind the liquid crystal display device, in order to fix pressing around their back, the liquid crystal the frame surrounding the periphery of the image display surface of the display device, near the end of the pawl projecting beyond the back of the accessory members, each provided with a hole, each hole, the peripheral outer, respectively, the tapered pin inserted, let me hold the back of the accessory member at the end side of the pin passing through the hole, and so as to fix the accessory member. そのために用いるピンには、線材から製作したものを用いるか、又は、ピン挿入時にピンの断面が比較的容易に弾性的に縮小変形するように、断性のある金属の板を曲げて中空に形成したものを用いる。 The pins used for its, or used after made from wire or, as during pin insertion pin cross section are relatively easily elastically shrinking deformation, hollow by bending the plate of metal with a cross resistance used as formed. また、先細のピンの断面が爪の孔の断面より大きくなった個所の太い側に溝状段差部を設け、そこでのピンの断面を爪の孔の断面より僅かに大きい程度に、 Further, the groove-like stepped portion in the thick side of greater than became point section of tapered pin cross-section nail hole is provided, wherein the pins of the cross-section slightly larger than the cross section of the nail holes of,
少なくともピンの先細側に対しては急激に縮小させ、ピンの抜止め作用を行わせるようにした。 Abruptly reduced at least for the pin tapered side, and so as to perform a retaining action of the pin. 更に、ピンの断面輪郭および爪に設けた孔の輪郭を、それぞれほぼ同様な四角形に形成させた。 Furthermore, the contour of the hole formed in the cross-sectional profile and the pawl pins, respectively is formed on substantially the same square.

【0006】 [0006]

【作用】上記のようにすれば、フレーム周辺から画像表示部の背後側に伸びる爪の先が分解作業中に折れて、フレーム全体を取替えなければならなくなると言うような問題はなくなる。 [Action] If, as described above, broken tip of the nail extending from the peripheral frame behind side of the image display unit during the decomposition work, is no longer a problem, such as say, will have to replace the entire frame. フレームの材料を比較的強度の高いものとし、ピンを比較的軟らかい塑性変形し易い材料で作れば、ピン材料が線材の場合に、ピンを強く押し込むことによって、フレームの爪の孔にピンの断面形状が変形して良く馴染み、ピンは抜け難くなる。 Shall relatively high strength material of the frame, if you make in an easy material relatively softer plastic deformation pin, if the pin material is a wire, by slamming the pin, the pin holes of the nail of the frame section shape familiar well deformed, the pin is not easily released. また、ピンを弾性のある金属板を中空に曲げて製作した場合、ピンを押し込む時に断面形状が弾性的に変形して、フレームの爪の孔に押し込み易くなる。 Further, when fabricated by bending pin a metal plate with a resilient hollow sectional shape when pushing the pin is elastically deformable, easily pushed into the holes of the nail frame. しかし、此の場合はピンに抜け止め用の溝状段差部を設けておく方が安全で、また、 However, in the case of 此 it is safe to have a groove-like stepped portion for retaining the pin, also,
金属板材を用いている場合には、上記段差部を形成させる加工作業は容易である。 In the case of using a metal plate material, machining operations to form the stepped portion it is easy. なお、本発明による場合、フレームの爪に設けた孔の周縁部の画像表示面に近い側は、固定すべき付属部材の背面より必ず画像表示面に近く位置するようにしておけば、ピンを孔に挿入したときに、製造ロットの相違などにより部材の寸法に僅かな相違があっても、ピンによって確実に付属部材を押さえ付けることができる。 In the case according to the present invention, the side close to the image display surface of the peripheral edge of the hole formed in the nail of the frame, if so as to be positioned closer to always image display surface than the back of the accessory members to be fixed, the pins when inserted into the hole, even if there is a slight difference in dimensions of members due to the difference in production lot can be pressed reliably armatures by a pin. なお、本発明に係るピンの断面形状が、フレームの爪の孔に対して回転し易い形状であると、抜け易くなったりする恐れがあるから、断面を双方とも、ほぼ四角にした。 The cross-sectional shape of the pin according to the present invention, if it is easily shaped to rotate relative to the hole of the nail of the frame, because there is a risk of or become easily removed, both the cross section and substantially square. これは、三角では角の形状に、 This is the shape of the corner is triangular,
孔とピンとで僅かな相違があっても使用し難くなり、また、このような小さな寸法のもので四角以上の多角形断面にすると実際上円形と同様になってしまうからである。 Even if there is a slight difference between the hole and the pin it becomes difficult to use and, because becomes similar to the practice round to square or polygonal cross-section at one of such small dimensions.
