図1により、本発明に係るディスプレイパネル嵌合構造が適用されるディスプレイパネルの基本構造を説明する。図1中、前面パネル1と背面パネル2とは、互いの接合面1F、2Fを合わせて分解可能に固定保持される関係にある。前面パネル1は一番上に位置し、略矩形で底の浅い筐体状をなし、下向きの立下り部は略矩形状をした構造部をしていて、この枠状の構造部における下側開放端の略矩形の平坦な縁部で、背面パネル2との接合面1Fを構成している。図1中、最も下に位置する背面パネル2は略矩形で、断面L字状をした枠状の構造部材であり、この枠状の構造部における上側開放端の略矩形の平坦な縁部で、前面パネル1との接合面1Fと接合される接合面2Fを構成している。
図2乃至図6において、背面パネル2に対する前面パネル1の組み立てに際して前面パネル1を背面パネル2に対してスライドさせる方向として定めた所定スライド方向Zを、短手方向Yに沿う突出部7u、7d設置側から非設置側に向かう向きとする。
図2、図4、図5において、背面パネル2における所定スライド方向Zの下流側の一辺部22には、凸状部9aを有するL字状の凸状嵌合部材9がその接合面2Fと同じ面位置で設けられている。図3~図5において、前面パネル1における所定スライド方向Zでの下流側の一辺部12には、対向片部22の凸状嵌合部材9に形成された凸状部9aと嵌合する孔8aを有する輪状嵌合部材8がその先端部を接合面1Fから突出させて設けられている。但し、図2では前面パネル1の裏側に位置するため図示されていない。
輪状嵌合部材8と凸状部9aとが嵌合する部位はそれぞれテーパ面を有しており、このテーパがスライド嵌合時のガイドなり、組み付けやすく、組付けた後ではガタツキおよび外形ズレを押さえることが可能となる。
背面パネル2に対して前面パネル1が所定スライド方向Zの上流側にずれることを防止して複数対の嵌合手段による嵌合状態を保持し、また、必要に応じてかかる保持を解除できるロック手段が必要である。このロック手段としては、最も簡単には背面パネル2及び前面パネル1の肉厚部を共通に通るピンを抜き差し可能に設けることで可能である。ただ、ピンだと、抜けやすかったり、逆に嵌合がかたすぎて必要な場合に抜けなかったり、或いは抜いたピンを紛失する可能性もある。
(一対の嵌合手段の近傍に設けられるロック手段)
図3において一般的な配置例を示すように、ロック手段30は、一対の嵌合手段である輪状嵌合部材8及び凸状嵌合部材9の近傍に配置され、前面パネル1の一辺部11の内側に設けた鉤状部材20と、この鉤状部材20に掛かる板状の掛止部材25からなり、一対の嵌合部材の嵌合のため、背面パネル2に対して前面パネル1が所定スライド方向Zにスライドするのに伴い、掛止部材25に対する鉤状部材20の係合がなされ、掛止機能により両パネルのずれによる嵌合の離脱は生じなくなる。また、このロック状態を解除する解除手段を有している。
掛止部材25の上面には、掛止解除用の棒31を差し込むための溝25cを形成しておく。
(L字形板状片同士による嵌合構造)
背面パネル2と前面パネル1とを接合状態にする一対の嵌合手段の例としては、輪状嵌合部材8及び凸状嵌合部材9の例を説明したが、本例はその別例であり、図18に示すように、図中斜め左側に位置する一対の嵌合手段を構成する第1、第2嵌合部材は共にL字形をした板状片からなり、第1嵌合部材を構成する板状片40は前面パネル1の短手方向の側壁内面に固定され、第2嵌合部材を構成する板状片41は背面パネル2の短手方向の側壁に固定されている。
(軸保持用突出部に設けたロック手段)
図2、図3、図21~図22において、突出部7uにはロック手段を構成する鉤状部材50が設けられ、この鉤状部材50に掛かる掛止部材51が突出部7dに設けられている。
鉤状部材50と掛止部材51との関係は、図7乃至図17で説明した鉤状部材20と、この鉤状部材20に掛かる掛止部材25との関係と同じである。突出部7u、7dを利用してロック手段を構成することにより、確実な掛止機能を得る。ロックの解除は、外力により鉤状部材50を弾性変形させて行う。鉤状部材及び掛止部材からなるロック手段は、前記一対の嵌合手段の近傍に設けることにより、嵌合状態を的確に誤差を含まずに適正な嵌合状態でロックできる。図22に示したように、鉤状部材50の掛止部材51に対する当接部は、所定のスライド方向に掛止部材51を押圧する傾斜面50aで構成すれば、該傾斜面50aを介して前側パネル1が背面パネル2に対して所定のスライド方向Zに常時加圧されるので、一対の嵌合手段による嵌合状態にゆるみを生じない。
