以下に従来のパンチングメタルの固定構造について説明する。 図７は従来のパンチングメタルの固定構造を備えたスピーカーグリルを示すもの であり、図７において、金属板のパンチングメタル１の平板部には多数の***３ が開口しており、図８に示すように周縁部１ａは折り曲げられて、その先端１ｂ は樹脂製のグリル枠２の周辺の溝２ａに挿入され、パンチングメタル１とグリル 枠２の全周が誘導加熱によって加熱されて、パンチングメタル１の先端１ｂがグ リル枠２の溝２ａに溶着固定されていた。 A conventional punching metal fixing structure will be explained below. Figure 7 shows a speaker grill with a conventional punched metal fixing structure. In FIG. 7, there are many small holes 3 in the flat part of the punched metal 1 of the metal plate. is open, and as shown in FIG. 8, the peripheral edge 1a is bent and the tip 1b is inserted into the groove 2a around the resin grill frame 2, and the punching metal 1 and the grill The entire circumference of the frame 2 is heated by induction heating, and the tip 1b of the punching metal 1 is heated by induction heating. It was welded and fixed to the groove 2a of the rill frame 2.
【０００３】0003
しかしながら上記の従来の構成では、パンチングメタル１とグリル枠２の全周 が誘導加熱されるために、加熱時間が長くかかり、且つ、金属と樹脂の熱膨張係 数が異なるために、誘導加熱によってパンチングメタル１とグリル枠２とに寸法 差が生じ、グリル枠２が変形してリアパーセルへ取付けたときに見栄えを損なう などの問題点を有していた。 However, in the above conventional configuration, the entire circumference of the punching metal 1 and the grill frame 2 is Because it is induction heated, it takes a long time to heat, and the thermal expansion relationship between metal and resin is Because the numbers are different, the dimensions of punching metal 1 and grill frame 2 are adjusted by induction heating. This will cause the grille frame 2 to deform and spoil its appearance when attached to the rear parcel. It had problems such as.
【０００４】 また、変形に耐えるためにグリル枠２の樹脂材料をグレードアップする必要が あり、コストがかかるなどの問題点を有していた。0004 In addition, it is necessary to upgrade the resin material of grill frame 2 to withstand deformation. However, there were problems such as high costs.
【０００５】 本考案は上記従来の問題点を解決するもので、誘導加熱の時間が短くてグリル 枠２に変形を生じさせず、樹脂材料をグレードダウンすることの出来るパンチン グメタルの固定構造を提供することを目的とする。[0005] This invention solves the above-mentioned conventional problems, and the induction heating time is short and grilling A punch that can downgrade the resin material without causing deformation of the frame 2. The purpose is to provide a fixed structure for metal.
【０００６】[0006]
この目的を達成するために本考案のパンチングメタルの固定構造は、周縁部が 誘導加熱によって枠部材の周辺の溝に溶着固定されるパンチングメタルの周縁部 の直線部分に溶着用の爪を設けた構成を有している。 To achieve this purpose, the perforated metal fixing structure of the present invention has a Peripheral edge of punched metal that is welded and fixed to the groove around the frame member by induction heating It has a configuration in which a welding claw is provided on the straight part of the welding part.
【０００７】[0007]
この構成によって、パンチングメタルと枠部材の誘導加熱される部分は溶着用 の爪の周囲のみであるため、加熱時間が短くてすみ、誘導加熱によってパンチン グメタルと枠部材とに生じる寸法差は枠部材のコーナー部分で吸収され、従って グレードの低い樹脂材料を使用しても枠部材に変形を生じることがなく、リアパ ーセルへ取付けたときに見栄えが良い。 With this configuration, the parts of the punching metal and frame member that are heated by induction are used for welding. Because the area is only heated around the nails, the heating time is short, and the induction heating makes it possible to prevent punching. Dimensional differences between the frame metal and the frame member are absorbed by the corner parts of the frame member, and therefore Even if low-grade resin materials are used, the frame members will not be deformed and the rear panel will not be deformed. - Looks good when attached to the cell.

【００１０】 図２は本考案に係わるパンチングメタルの固定構造を備えたスピーカーグリル １０の斜視図である。スピーカーグリル１０はスピーカーを覆うパンチングメタ ル１と、このパンチングメタル１を固定する枠部材であるグリル枠２とで構成さ れている。金属板のパンチングメタル１の平板部には多数の***３が開口してス ピーカーの音を透過させる。また、パンチングメタル１の周縁部１ａは平板部に 対して略直角に折り曲げられており、この周縁部１ａの直線部分の略中心位置に はグリル枠２に溶着固定される爪４が突設されている。0010 Figure 2 shows a speaker grill with a fixed structure of punched metal according to the present invention. 10 is a perspective view of FIG. The speaker grill 10 is a punching metal that covers the speaker. It consists of a grill frame 2, which is a frame member that fixes the punching metal 1. It is. A large number of small holes 3 are opened in the flat plate part of the punching metal 1 of the metal plate. Allows the sound from the speaker to pass through. Also, the peripheral edge 1a of the punching metal 1 is a flat plate part. It is bent at a substantially right angle to the periphery 1a, and is located approximately at the center of the straight portion of the peripheral edge 1a. A protruding claw 4 is welded and fixed to the grill frame 2.
【００１１】 グリル枠２は図３に示すように、周縁部２ｂの内側に溝２ａが形成され、この 溝２ａの中にパンチングメタル１の周縁部１ａが挿入されていて、爪４の先端は グリル枠２の溝２ａの底面に接している。そして図４に示すように、パンチング メタル１の周縁部１ａのコーナー部分の先端１ｂはグリル枠２の溝２ａに対して 、上下、左右方向に何れも０、５〜１ｍｍのクリアランスｓ、ｔをもって挿入さ れている。[0011] As shown in FIG. 3, the grill frame 2 has a groove 2a formed inside a peripheral edge 2b. The peripheral edge 1a of the punching metal 1 is inserted into the groove 2a, and the tip of the claw 4 is It is in contact with the bottom surface of the groove 2a of the grill frame 2. And as shown in Figure 4, punching The tip 1b of the corner portion of the peripheral edge 1a of the metal 1 is aligned with the groove 2a of the grill frame 2. , with clearances s and t of 0.5 to 1 mm in both the vertical and horizontal directions. It is.
【００１２】 以上のように構成されたパンチングメタルの固定構造について、以下その動作 について説明する。パンチングメタル１の周縁部１ａの爪４の部分をグリル枠２ と共に誘導加熱すると、爪４とこの爪４の周囲のグリル枠２の溝２ａが加熱され て、パンチングメタル１をグリル枠２の溝２ａに押し付けると、爪４が溝２ａの 底面に喰い込んで溶着固定される。0012 The operation of the punching metal fixing structure constructed as above is explained below. I will explain about it. The claw 4 part of the peripheral edge 1a of the punching metal 1 is attached to the grill frame 2. When induction heating is performed along with this, the claw 4 and the groove 2a of the grill frame 2 around the claw 4 are heated.

【００１３】 この時、誘導加熱される部分はパンチングメタル１の爪４と、その周囲のみで あるため、加熱時間が短く金属と樹脂の熱膨張係数の差異によるパンチングメタ ル１とグリル枠２の寸法差も小さい。また、僅かな寸法差が生じても、パンチン グメタル１の周縁部１ａのコーナー部分の先端１ｂのクリアランスｓ、ｔが変形 に対する逃げとなって、寸法差はグリル枠２のコーナー部分で吸収されグリル枠 ２の変形を防止することが出来る。[0013] At this time, the only part that is induction heated is the claw 4 of the punching metal 1 and its surroundings. Due to the short heating time and difference in thermal expansion coefficient between metal and resin, punching metal The dimensional difference between the frame 1 and the grill frame 2 is also small. In addition, even if there is a slight dimensional difference, the punch The clearances s and t of the tip 1b of the corner portion of the peripheral edge 1a of the metal 1 are deformed. The dimensional difference is absorbed by the corner part of the grill frame 2 and the grill frame 2 deformation can be prevented.
【００１４】 以上のように本実施例によれば、周縁部１ａが誘導加熱によってグリル枠２の 溝２ａに溶着固定されるパンチングメタル１の周縁部１ａの直線部分に溶着用の 爪４を設けたことにより、パンチングメタル１とグリル枠２の誘導加熱される部 分は溶着用の爪４の周囲のみであるため、加熱時間が短くてすみ、誘導加熱によ ってパンチングメタル１とグリル枠２とに生じる寸法差はグリル枠２のコーナー 部分で吸収され、従ってグレードの低い樹脂材料を使用してもグリル枠２に変形 を生じることがなく品質も向上し、リアパーセル２０へ取付けたときに見栄えが 良い。[0014] As described above, according to this embodiment, the peripheral portion 1a of the grill frame 2 is heated by induction heating. A welding tool is attached to the straight part of the peripheral edge 1a of the punching metal 1 which is welded and fixed to the groove 2a. By providing the claws 4, the parts of the punching metal 1 and the grill frame 2 that are heated by induction Since the heating time is only around the welding claw 4, the heating time is short and induction heating is used. The dimensional difference that occurs between the punching metal 1 and the grill frame 2 is the corner of the grill frame 2. Therefore, even if low grade resin material is used, it will not be transformed into grill frame 2. The quality is improved without causing any damage, and it looks good when attached to the rear parcel 20. good.
【００１５】 また、本考案の変形例として図５及び図６に示すように、パンチングメタル１ のコーナー部分に爪５を突設し、この爪５をグリル枠２の溝２ａの底面に設けた 孔２ｃに挿通して先端をグリル枠２の底面に折り曲げ、爪５と孔２ｃに僅かの遊 びを持たせておくと、パンチングメタル１のコーナー部分がグリル枠２から浮き 上がることを防ぐことが出来る。[0015] In addition, as a modification of the present invention, as shown in FIGS. 5 and 6, a punching metal 1 A claw 5 is provided protrudingly at the corner portion of the grill frame 2, and this claw 5 is provided on the bottom surface of the groove 2a of the grill frame 2. Insert it into the hole 2c and bend the tip to the bottom of the grill frame 2, leaving a slight play between the claw 5 and the hole 2c. If the corner part of the punching metal 1 is left floating, the corner part of the punching metal 1 will be lifted from the grill frame 2. You can prevent it from rising.
