る。For this reason, the base 40 is fixed in a state where the lower surface of the bottom plate 42 is almost in close contact with the support surface 22 of the speaker box 21.
一方、回転板50ついては、図示しないが、ベース40と
同様にして、上段に位置するスピーカボックス20の下面
に、その軸部51及び鍔部54を下方に向けた状態で固定す
る。On the other hand, although not shown, the rotating plate 50 is fixed to the lower surface of the speaker box 20 located at the upper stage, with the shaft portion 51 and the flange portion 54 facing downward, similarly to the base 40.
こうして、ベース40と回転板50とを、各スピーカボッ
クス20,21に各々固定したならば、回転板50の軸部51及
び鍔部54を、ベース40の軸受部41の開口部47に合わせ
て、横から差し込めばよい。When the base 40 and the rotating plate 50 are fixed to the respective speaker boxes 20 and 21 in this way, the shaft 51 and the flange 54 of the rotating plate 50 are aligned with the opening 47 of the bearing 41 of the base 40. , Just insert it from the side.
回転板50を差し込むと、その軸部51が、ベース40の突
縁部46の両突起部46aに係合する。ここで、軸部51を押
し込むと、突起部46aが軸部51の外周面に押されて、突
縁部46の内径が僅かに拡径することで、突起部46aを乗
り越えて、第15,16図に示すように、突縁部46の内縁内
にはまり込む。When the rotating plate 50 is inserted, the shaft portion 51 engages with both the protruding portions 46a of the protruding edge portion 46 of the base 40. Here, when the shaft portion 51 is pushed in, the protrusion 46a is pressed against the outer peripheral surface of the shaft portion 51, and the inner diameter of the protruding edge portion 46 is slightly increased. As shown in FIG. 16, the projection 46 fits inside the inner edge of the projection 46.
軸部51が突縁部46の内縁にはまり込むと、突縁部46が
樹脂の弾性復元力により縮径することで、円周方向に外
れ難くなる。When the shaft portion 51 fits into the inner edge of the protruding edge portion 46, the protruding edge portion 46 is reduced in diameter by the elastic restoring force of the resin, so that it is difficult to come off in the circumferential direction.
又、突縁部46の内径が、鍔部54の外径より小さいこと
から、鍔部54の上面が突縁部46の下面に当接すること
で、軸部51は、その軸方向にも抜けなくなる。In addition, since the inner diameter of the protruding portion 46 is smaller than the outer diameter of the flange portion 54, the upper surface of the flange portion 54 comes into contact with the lower surface of the protruding portion 46, so that the shaft portion 51 also comes off in the axial direction. Disappears.
こうして、回転板50の軸部51及び鍔部54が、ベース40
の軸受部41内にはまり込むことで、回転板50がベース40
に対して回転可能に支持される。Thus, the shaft portion 51 and the flange portion 54 of the rotating plate 50
The rotating plate 50 is inserted into the bearing 41 of the
It is rotatably supported with respect to.
つぎに、ベース40に対して連結部材60を装着する。 Next, the connecting member 60 is mounted on the base 40.
すなわち、連結部材60は、その軸受部62をベース40の
軸受部41の開口部47に合わせて横から挿入する。連結部
材60を挿入すると、その両弾性係止部63が、ベース40の
両係止爪部44aに各々係合する。ここで、連結部材60

撓みながら、ベース40の外周壁44の内側にはまり込む。That is, the connecting member 60 is inserted from the side so that the bearing 62 is aligned with the opening 47 of the bearing 41 of the base 40. When the connecting member 60 is inserted, the two elastic locking portions 63 are engaged with the both locking claws 44a of the base 40, respectively. Here, the connecting member 60
Is strongly pressed toward the base 40, the folded pieces 65 of both elastic locking portions 63 are pressed against the inclined inner surfaces of the locking claws 44a, and oppose each other against the elastic force of the resin. While bending inward, it fits inside the outer peripheral wall 44 of the base 40.
そして、折返し片65の係合段部66が、係止爪部44aの
位置まで進むと、各折返し片65が樹脂の弾性復元力によ

係止爪部44aがはまり込む、両部の係合により、連結部
材60がベース40より外れなくなる。又、このとき、連結
部材60の両弾性係止部63が、ベース40の各窓部44bに各
々臨む。When the engagement step 66 of the folded piece 65 advances to the position of the locking claw 44a, each folded piece 65 is restored by the elastic restoring force of the resin, and as shown in FIG. The engaging claw 44a fits into the step 66, and the engagement of the two prevents the connecting member 60 from coming off the base 40. At this time, both elastic locking portions 63 of the connecting member 60 face the respective windows 44b of the base 40.
さらに、連結部材60の軸承部62は、第15,16図に示す
ように、ベース40の開口部47を通してその軸受部41内に
はまり込むことで、その湾曲部64がベース40の軸受部41
内にはまり込んでいる回転板50の軸部51の外周に臨む。
このため、連結部材60の湾曲部64が、開口部47側より回
転板50の軸部51の外周に臨むことで、軸部51がその円周
方向に外れなくなる。Further, as shown in FIGS. 15 and 16, the bearing portion 62 of the connecting member 60 fits into the bearing portion 41 through the opening 47 of the base 40 so that the curved portion 64 of the bearing portion 41
It faces the outer periphery of the shaft portion 51 of the rotary plate 50 that is stuck inside.
Therefore, the curved portion 64 of the connecting member 60 faces the outer periphery of the shaft portion 51 of the rotating plate 50 from the opening 47 side, so that the shaft portion 51 does not come off in the circumferential direction.
こうして、上下のスピーカボックス20,21は、第2,3図
に示すように、支持装置30を介して互いに連結され、上

上段に位置するスピーカボックス20に対して回転可能で
あるため、両スピーカボックス20,21は、支持装置30を
介して互いに回転可能に連結される。このように、2台
のスピーカボックス20,21を回転可能に連結することに
より、両スピーカの向き等を異ならせることができ、最
適なリスニングエリアを設定することができる。Thus, the upper and lower speaker boxes 20, 21 are connected to each other via the support device 30, as shown in FIGS. 2 and 3, so that the upper speaker box 20 is positioned relative to the lower speaker box 21. The lower speaker box 21 is also rotatable with respect to the upper speaker box 20, so that both speaker boxes 20, 21 are supported via the support device 30. Are rotatably connected to each other. Thus, by connecting the two speaker boxes 20 and 21 rotatably, the directions of the two speakers can be made different, and an optimal listening area can be set.
一方、両スピーカボックス20,21を取り外すには、ま
ず、連結部材60を外せばよい。On the other hand, to remove both speaker boxes 20 and 21, first, the connecting member 60 may be removed.
連結部材60を外すには、ベース40の各窓部44bを通し
て、連結部材60の各弾性係止部63を各々押し込めばよ
い。To remove the connecting member 60, the respective elastic locking portions 63 of the connecting member 60 may be pushed through the respective windows 44b of the base 40.
両弾性係止部63を押し込むと、各折返し片65が樹脂の
弾性力に抗して、相対向して内向きに撓み込み、各先端
部の係合段部66が、ベース40の各係止爪部44aから係脱
する。When the two elastic locking portions 63 are pushed in, the folded pieces 65 are bent inward in opposition to each other against the elastic force of the resin, and the engaging step portions 66 at the respective distal end portions are engaged with the respective engaging portions of the base 40. It is disengaged from the pawl portion 44a.
そして、係合段部66が係脱したならば、連結部材60を
ベース40から引き抜けばよい。連結部材60を引き抜く
と、その軸承部62がベース40の開口部47より抜けて、開
口部47が開放される。Then, when the engaging step 66 is disengaged, the connecting member 60 may be pulled out from the base 40. When the connecting member 60 is pulled out, the bearing 62 thereof comes off from the opening 47 of the base 40, and the opening 47 is opened.
つぎに、開放された開口部47を通して、回転板50の軸
部51及び鍔部54を、ベース40の軸受部41より横に引き抜
けばよい。Next, the shaft portion 51 and the flange portion 54 of the rotating plate 50 may be pulled laterally from the bearing portion 41 of the base 40 through the opened opening 47.
その際に、回転板50の軸部51が、ベース40の突縁部46
の両突起部46aに係合し、ここでさらに強く引き抜こう
とすると、突起部46aが軸部51の外周面に押されて、突
縁部46の内径が僅かに拡径することで、突起部46aを乗
り越えて外れる。At this time, the shaft portion 51 of the rotating plate 50 is
If the projection 46a is pushed further by the outer peripheral surface of the shaft portion 51, and the inner diameter of the projection 46 is slightly increased, the projection 46a is pressed. Get over 46a.
こうして、回転板50をベース40より抜き取ると、上段
に位置するスピーカボックス20が、その下段に位置する
スピーカボックス21から外れ、両スピーカボックス20,2
1を相互に分離することができる。In this way, when the rotating plate 50 is removed from the base 40, the speaker box 20 located at the upper stage is disengaged from the speaker box 21 located at the lower stage, and the two speaker boxes 20, 2
1 can be separated from each other.
尚、本実施例では、2台のスピーカボックス20,21を
