【実施例】【Example】

以下、本考案を図示の実施例について詳細に説明する。 1はカーステレオ用のスピーカ本体、2はスピーカ本体1を取付ボード10の スピーカ取付孔11に表側から嵌合したとき外周部分3の裏面がスピーカ取付孔 11の孔縁の外周表面に当接されるスピーカグリルである。そして、このスピー カグリル2の外周部分3の裏面には常時は爪先が該スピーカグリル2の外縁より 外側に張り出した状態を保持するが必要時に図1に鎖線で示すようにスピーカグ リル2の外縁程度まで強制屈曲可能な弾性爪片4と、取付ボード10のスピーカ 取付孔11に近い位置に配設された孔に嵌合されて超音波ウエルダでとにより圧 潰溶着されるかしめ用のボス5がいずれも3個程度交互に配設されている。 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 is a speaker body for car stereo, 2 is a speaker body 1 when the speaker body 1 is fitted into the speaker mounting hole 11 of the mounting board 10 from the front side, the rear surface of the outer peripheral portion 3 is brought into contact with the outer peripheral surface of the speaker mounting hole 11. It is a speaker grill. On the back surface of the outer peripheral portion 3 of the speaker grill 2, the state in which the toes are projected outward from the outer edge of the speaker grill 2 is always held, but when necessary, as shown by the chain line in FIG. Up to the elastic claw piece 4 that can be forcibly bent, and the boss 5 for crimping, which is fitted into a hole provided in a position near the speaker mounting hole 11 of the mounting board 10 and crushed and welded by an ultrasonic welder. In each case, about three pieces are arranged alternately.

【0007】 各弾性爪片4はスピーカグリル2の略水平な外周部分3の裏面に鍵形に弾性プ ラスチックスをもって一体成形されたもので、スピーカグリル2の外周部分3の 裏面に続かせた脚部6に外面は該外周部分3と略並行するが内面は外周部分3に 対して所要の傾斜角度をもって外向きに拡開されたテーパ状押え部7に形成して あるストッパ爪8を連設したものとしている。なお、この弾性爪片4は常時は爪 先がスピーカグリル2の外縁より外側に張り出した状態を保持するが必要時にス ピーカグリル2の外縁程度まで強制屈曲可能で且つ内面がスピーカグリル2の外 周部分に対して外向きに拡開されたテーパ状押え部に形成されるものであれば、 前記した実施例のものに限定されることはなく、例えば、ターンオーバ方式とし てもよい。Each elastic claw piece 4 is integrally formed on the rear surface of the substantially horizontal outer peripheral portion 3 of the speaker grill 2 with a key-shaped elastic plastic, and the leg connected to the rear surface of the outer peripheral portion 3 of the speaker grill 2 is formed. An outer surface of the portion 6 is substantially parallel to the outer peripheral portion 3, but an inner surface of the portion 6 is provided with a stopper claw 8 formed in a tapered pressing portion 7 which is expanded outward at a required inclination angle with respect to the outer peripheral portion 3. It is supposed to have been done. The elastic claw piece 4 always keeps its toes protruding outward from the outer edge of the speaker grill 2, but can be forcibly bent to the outer edge of the speaker grill 2 and the inner surface of the speaker grill 2 can be forcibly bent when necessary. The present invention is not limited to the above-described embodiment as long as it is formed in the tapered pressing portion that is expanded outward with respect to the portion, and for example, a turnover method may be used.

【0008】 このように構成されたものは、常時はスピーカグリル2の外縁より外側に張り 出した状態を保持している弾性爪片4のストッパ爪8の爪先をスピーカグリル2 の外縁程度まで強制屈曲させた状態として取付ボード10のスピーカ取付孔11 に表側から嵌合すれば、弾性爪片4のストッパ爪8はスピーカ取付孔11を通過 した時点で爪先がスピーカグリル2の外縁より外側に張り出した正常状態に自動 復帰するから、スピーカグリル2の外周部分3に対し外向きに拡開されたテーパ 状押え部7に形成してあるストッパ爪8は内面の外向きに拡開されたテーパ状押 え部7のいずれかの部位が取付ボード10の肉厚に若干のばらつきがあってもス ピーカ取付孔11の孔縁に当接し、該テーパ状押え部7とスピーカグリル2の外 周部分3との間で取付ボード10のスピーカ取付孔11の孔縁を的確に挟持する こととなり、このため、スピーカ本体1は取付ボード10に対してがたつきのな い状態で保持されることとなる。従って、スピーカグリル2の外周部分3の裏面 に配設してあるかしめ用のボス5などによる本格的な固定固定箇所を少なくして も走行振動によるがたつきが生じることのないものとなり、スピーカ本体1を取 付ボード10に装着する作業穿設極めて簡易化できることとなる。With such a structure, the toes of the stopper claws 8 of the elastic claw pieces 4 that always keep the state protruding outward from the outer edge of the speaker grill 2 are forced to the outer edge of the speaker grill 2. If it is bent and fitted into the speaker mounting hole 11 of the mounting board 10 from the front side, the stopper claw 8 of the elastic claw piece 4 projects outward from the outer edge of the speaker grill 2 when the stopper claw 8 passes through the speaker mounting hole 11. Since it automatically returns to the normal state, the stopper claw 8 formed on the taper-shaped pressing portion 7 which is expanded outward with respect to the outer peripheral portion 3 of the speaker grill 2 has a tapered shape which is expanded outward on the inner surface. Even if there is a slight variation in the wall thickness of the mounting board 10, any part of the holding portion 7 comes into contact with the hole edge of the speaker mounting hole 11, and the outer periphery of the tapered holding portion 7 and the speaker grill 2 is increased. Since the hole edge of the speaker mounting hole 11 of the mounting board 10 is accurately sandwiched between the part 3 and the speaker body 1, the speaker body 1 is held against the mounting board 10 without rattling. Become. Therefore, rattling due to traveling vibration does not occur even if the number of full-scale fixed and fixed parts such as the boss 5 for caulking provided on the back surface of the outer peripheral portion 3 of the speaker grill 2 is reduced. The work drilling for mounting the main body 1 on the mounting board 10 can be extremely simplified.

【考案の効果】[Effect of the device]

本考案は前記説明によって明らかなように、スピーカグリルの裏面に常時は爪 先が該スピーカグリルの外縁より外側に張り出した状態を保持するが必要時にス ピーカグリルの外縁程度まで強制屈曲可能で且つ内面はスピーカグリルの外周部 分に対して外向きに拡開されたテーパ状押え部に形成してある弾性爪片を適当数 配設しておくだけで、ビス止めその他の本格的な固定箇所を少なくしても走行振 動によるがたつきが生じることがないうえに、弾性爪片のテーパ状押え部とスピ ーカグリルの外周部分との間で取付ボードのスピーカ取付孔の孔縁に的確に挟持 された状態となったスピーカ本体は完全な仮止め状態となるのでビス止めその他 の本格的な固定作業上も極めて便利になるなど多くの利点がある。 従って、本考案は従来の問題点を解消したカーステレオ用スピーカとして実用 的価値極めて大なものである。 As is apparent from the above description, the present invention maintains the state in which the toes of the speaker grill always extend outward from the outer edge of the speaker grill, but can be forcibly bent to the outer edge of the speaker grill and the inner surface when necessary. The screw clamps and other full-scale fixing points can be secured simply by arranging an appropriate number of elastic claw pieces that are formed on the tapered pressing part that expands outward with respect to the outer peripheral part of the speaker grill. Even if it is minimized, rattling due to running vibration does not occur, and it is properly clamped between the tapered holding part of the elastic claw piece and the outer peripheral part of the speaker grill at the edge of the speaker mounting hole of the mounting board. Since the speaker body in the fixed state is in a completely temporarily fixed state, it has many advantages such as being extremely convenient for screw fixing and other full-scale fixing work. Therefore, the present invention has a great practical value as a car stereo speaker that solves the conventional problems.
