Description

本発明は、スピーカーパネルに形成された取り付け爪と、この爪と嵌合するスピーカーキャビネット係合部を改良した合成樹脂部品の係合構造と、その容易な係合解除構造に関するものである。   The present invention relates to an attachment structure formed on a speaker panel, an engagement structure of a synthetic resin part in which a speaker cabinet engagement portion that is fitted to the connection panel is improved, and an easy engagement release structure thereof.

図９に示すように、例えばスピーカーパネル１に形成された取り付け爪２を、この爪と嵌合するスピーカーキャビネット３の開口部４ｃに軽く押し付けることにより、爪２が撓んで爪と系合部４ｃとが容易に係合する。系合解除は、開口部４ｃの外側から爪２を撓ませスピーカーパネル１を引き離し系合解除する。この構成のものは、爪の突起と係合部の開口により、位置決めと係合を行うものである。また、組み立て及び分解を容易にする方法には図９、図１０があるが、図９に示した形状は、爪の係合部に外観面に達する開口４ｃがあるため、外観品位を劣化させる欠点がある。図１０に示したネジ固定もあるが、固定部品８が増える事と外観面に大きな開口７ができるため、外観品位を著しく劣化させる欠点があった。   As shown in FIG. 9, for example, the attachment claw 2 formed on the speaker panel 1 is lightly pressed against the opening 4 c of the speaker cabinet 3 fitted to the claw, so that the claw 2 is bent and the claw and the mating portion 4 c are obtained. And engage easily. The system release is performed by bending the claw 2 from the outside of the opening 4c and pulling away the speaker panel 1 to release the connection. In this configuration, positioning and engagement are performed by the projection of the claw and the opening of the engagement portion. 9 and 10 are methods for facilitating assembly and disassembly, but the shape shown in FIG. 9 deteriorates the appearance quality because the engagement portion of the claw has an opening 4c reaching the appearance surface. There are drawbacks. Although there is also the screw fixing shown in FIG. 10, there is a disadvantage that the appearance quality is remarkably deteriorated because the fixing parts 8 are increased and a large opening 7 is formed on the appearance surface.

解決しようとする問題点は、爪と係合部の位置出しと係合は可能であるが、外観品位を維持し、係合後の容易な分解方法については何ら課題を解決しているものではない。   The problem to be solved is that the claw and the engaging part can be positioned and engaged, but the appearance quality is maintained, and there is no problem with the easy disassembly method after engagement. Absent.

本発明は、この点に鑑みてなされたものであり、スピーカーキャビネット３の係合部４に段差４ａを形成することにより回転方向の位置決めを行うと共に、その段差４ａの始まりから円周内肉厚部までの傾斜ガイド４ｂを回転方向に形成させることにより、スピーカーパネル（爪２）を円周方向（９）に回転させて、爪２と係合部４の係合を容易に複数の爪を同時に解除できる合成樹脂部品の回転方向の係合解除構造を提供することを目的とする。   The present invention has been made in view of this point. Positioning in the rotation direction is performed by forming a step 4a in the engaging portion 4 of the speaker cabinet 3, and the thickness in the circumference from the beginning of the step 4a. By rotating the speaker panel (claw 2) in the circumferential direction (9) by forming the inclined guide 4b to the part in the rotation direction, the claw 2 and the engagement part 4 can be easily engaged with each other with a plurality of claws. It is an object of the present invention to provide a disengagement structure in the rotational direction of a synthetic resin part that can be released simultaneously.

本発明は、スピーカーキャビネットに設けた係合部にスピーカーパネルの爪が係止する係合部を設けその係合部に爪幅より広い所に段差４ａを形成した。更に前記段差４ａの始まりから円周内肉厚部まで傾斜ガイド４ｂを円周方向に形成させたことを特徴とするものである。   In the present invention, the engaging portion provided in the speaker cabinet is provided with an engaging portion for locking the claw of the speaker panel, and the step 4a is formed in the engaging portion at a position wider than the claw width. Further, the inclined guide 4b is formed in the circumferential direction from the beginning of the step 4a to the inner thick part.

本発明は、スピーカーパネル爪２を円周方向（９）に軽く回転させることにより、スピーカーキャビネットの係合部回転方向段差内４ａに嵌合させ位置決めさせたものを、スピーカーパネル爪２に円周方向（９）に回転する力を加えることにより、スピーカーパネル全ての爪嵌合を円周方向に同時に完全解除することが可能となるものである。   In the present invention, the speaker panel claw 2 is slightly rotated in the circumferential direction (9) so that the speaker panel claw 2 is fitted and positioned in the step 4a in the rotation direction of the engaging portion of the speaker cabinet. By applying a rotating force in the direction (9), it is possible to completely release the claw fitting of all the speaker panels simultaneously in the circumferential direction.

本発明は、構成された合成樹脂部品の容易な係合構造であるので、スピーカーパネル爪をＸ軸方向に軽く加重することにより、スピーカーキャビネット係合部の円周方向段差内に、外観品位を損なうことなく嵌合させ、位置決めさせることができる利点がある。及び、嵌合後のスピーカーパネル爪に円周方向の回転する力を更に加えることにより、スピーカーキャビネットの係合部の全ての爪を、同時に円周方向段差上に移動させ、嵌合を容易に解除させることができる。更に、スピーカーパネルを円周方向に継続して回転させることにより、スピーカーパネル全ての爪嵌合を完全に同時に解除させ（特殊）工具無しで容易に分解可能とする利点がある。   Since the present invention is an easy engagement structure of the constructed synthetic resin parts, the appearance quality can be improved within the circumferential step of the speaker cabinet engaging portion by lightly loading the speaker panel claw in the X-axis direction. There is an advantage that it can be fitted and positioned without loss. And by further applying a circumferential rotating force to the speaker panel claws after mating, all the claws of the engaging part of the speaker cabinet are simultaneously moved on the circumferential step, making fitting easy It can be released. Further, by continuously rotating the speaker panel in the circumferential direction, there is an advantage that the claw fitting of all the speaker panels can be completely released simultaneously and can be easily disassembled without using a (special) tool.

容易な組み立て係合による位置決めと、円周方向に回転させて容易に係合解除構造を提供するという目的を、最少の部品点数で、合成樹脂部品の外観品位を損なわずに実現した。   The objectives of positioning by easy assembly engagement and providing an easily disengaged structure by rotating in the circumferential direction are realized with the minimum number of parts without impairing the appearance quality of the synthetic resin parts.
