　以下、本発明の筐体取り付け構造について、筐体がスピーカの筐体である場合に適用した実施形態を図面を参照しながら説明する。 Hereinafter, embodiments of the housing mounting structure of the present invention applied when the housing is a speaker housing will be described with reference to the drawings.
　スピーカ１は、特に限定されるものではないが、その筐体１０が、図４及び図５に示すように、スピーカユニット（図示略）を収容する本体部１１と、壁等の支持体４０への取り付け部１２とから構成されており、本体部１１の前面１１ａが放音面とされ、本体部１１の背部に取り付け部１２が設けられている。この場合、図６に示すように、本体部１１の背面に凸円弧面１１ｂが形成されるとともに、取り付け部１２の前面に凹円弧面１２ａが形成されており、これら凸円弧面１１ｂと凹円弧面１２ａとが摺動自在に突き合せられ、本体部１１の背部に設けた軸部１３（図７参照）が取り付け部１２の長穴１４（図８及び図９参照）を貫通して支持されている。この長穴１４は、凹円弧面１２ａの円弧の方向に沿って設けられており、両円弧面１１ｂ，１２ａに沿う本体部１１の摺動時に軸部１３が長穴１４に沿って移動できるようになっている。 The speaker 1 is not particularly limited. As shown in FIGS. 4 and 5, the housing 10 is connected to a main body 11 that houses a speaker unit (not shown) and a support body 40 such as a wall. The front surface 11 a of the main body 11 is a sound emitting surface, and the mounting portion 12 is provided on the back of the main body 11. In this case, as shown in FIG. 6, a convex arc surface 11b is formed on the back surface of the main body 11, and a concave arc surface 12a is formed on the front surface of the attachment portion 12. The convex arc surface 11b and the concave arc surface are formed. The shaft portion 13 (see FIG. 7) provided on the back portion of the main body portion 11 is supported by penetrating the long hole 14 (see FIGS. 8 and 9) of the mounting portion 12. ing. The long hole 14 is provided along the direction of the circular arc of the concave circular arc surface 12a so that the shaft portion 13 can move along the long hole 14 when the main body 11 slides along the circular arc surfaces 11b and 12a. It has become.
　この支持構造により、筐体１０は、図５の矢印で示すように、本体部１１を取り付け部１２に対して凸円弧面１１ｂ及び凹円弧面１２ａの円弧の方向に沿う一方向に首振りして、放音面１１ａの向きを変えられるようになっている。
　なお、図４等に示す例では、本体部１１は、放音面１１ａが正面視で矩形状に形成され、背面側に向かうにしたがって横断面が漸次円形に遷移する形状とされ、取り付け部１２は、その前面から背面に向かうにしたがって漸次拡径する円錐台状の外形に形成されている。
　そして、このスピーカ１が取り付け金具３０によって支持体４０の表面に固定される。 With this support structure, as shown by the arrow in FIG. 5, the housing 10 swings the main body portion 11 in one direction along the arc direction of the convex arc surface 11 b and the concave arc surface 12 a with respect to the attachment portion 12. Thus, the direction of the sound emitting surface 11a can be changed.
In the example shown in FIG. 4 and the like, the main body 11 has a sound emitting surface 11a formed in a rectangular shape when viewed from the front, and has a shape in which the cross section gradually changes to a circle as it goes to the back side. Is formed in a frustoconical outer shape that gradually increases in diameter from the front to the back.
And this speaker 1 is fixed to the surface of the support body 40 by the mounting bracket 30.
　図１において、符号４０が支持体を示しており、筐体１０及び取り付け金具３０の方向を示すときは、その支持体４０に取り付けられた姿勢を基準として、支持体４０の表面に沿う左右方向をＸ方向、上下方向をＹ方向、支持体４０の表面と直交する方向をＺ方向とする。また、筐体１０において、支持体４０に取り付けられたときに、前方を向く面を前面又は正面とし、支持体４０に対向する面を背面とする。また、本体部１１の放音面１１ａの中心から放音面１１ａと直交する方向を本体部１１の軸方向、取り付け部１２の円錐台状の外形の軸方向を取り付け部１２の軸方向、という場合もある。 In FIG. 1, reference numeral 40 indicates a support, and when the direction of the housing 10 and the mounting bracket 30 is indicated, the horizontal direction along the surface of the support 40 with reference to the posture attached to the support 40. Is the X direction, the vertical direction is the Y direction, and the direction orthogonal to the surface of the support 40 is the Z direction. In addition, in the housing 10, when attached to the support body 40, a surface facing the front is a front surface or a front surface, and a surface facing the support body 40 is a back surface. Further, the direction orthogonal to the sound emitting surface 11a from the center of the sound emitting surface 11a of the main body 11 is referred to as the axial direction of the main body 11, and the axial direction of the frustoconical outer shape of the mounting portion 12 is referred to as the axial direction of the mounting portion 12. In some cases.
　取り付け金具３０は、図１０に示すように、弾性を有する金属板を折り曲げ加工して形成されており、図１に示すように支持体４０の表面に固定された状態で、筐体１０の取り付け部１２の背面側の端部を固定する。
　取り付け金具３０は、支持体４０の表面に固定される固定部３１に、複数のばね片３２と、複数の円弧板状壁３３～３５とが一体に形成されるとともに、そのうちの一対の円弧板状壁３３の先端に爪部３６が一体に形成されている。
　固定部３１は、全体として円盤状に形成され、その背面が支持体４０への取り付け面３１ａとされており、その中央部に、取り付け姿勢を示す矢印の形状の指示部３７が形成されるとともに、この指示部３７の左右に、支持体４０に固定するためのねじを挿通する円弧状の孔部３８が形成されている。この場合、指示部３７も孔により形成されるが、図示例では、矢印の方向を下方向に向けて設けられている。 The mounting bracket 30 is formed by bending an elastic metal plate as shown in FIG. 10, and is attached to the surface of the support body 40 as shown in FIG. The end of the back side of the part 12 is fixed.
In the mounting bracket 30, a plurality of spring pieces 32 and a plurality of arc plate-like walls 33 to 35 are integrally formed on a fixed portion 31 fixed to the surface of the support 40, and a pair of arc plates is included. A claw portion 36 is integrally formed at the tip of the wall 33.
The fixing portion 31 is formed in a disk shape as a whole, and the back surface thereof is an attachment surface 31a to the support 40, and an instruction portion 37 in the shape of an arrow indicating the attachment posture is formed at the center portion thereof. In addition, arc-shaped holes 38 through which screws for fixing to the support body 40 are inserted are formed on the left and right sides of the instruction portion 37. In this case, although the instruction | indication part 37 is also formed with a hole, in the example of illustration, it has provided the direction of the arrow toward the downward direction.
　ばね片３２は、固定部３１の周囲に４個設けられており、固定部３１の半径方向に延びていることにより、固定部３１を中心に放射状に（周方向に９０°ずつ間隔をおいて）配置されている。これらばね片３２は、その基端部が固定部３１の外周部の一部を切り欠いた部分に設けられ、全体としては、固定部３１の支持体４０への取り付け面３１ａに沿うように設けられているが、図１０（ｃ）に示すように、取り付け面３１ａと厳密な面一状態ではなく、取り付け面３１ａから先端に向かうにしたがって取り付け金具３０の前方に向かってわずかな角度θの下り勾配に傾斜して設けられている。言い換えると、固定部３１の取り付け面３１ａを支持体４０の表面に接触させたときに、ばね片３２は、先端に向かうにしたがって支持体４０の表面から離れるように傾斜している。 Four spring pieces 32 are provided around the fixed portion 31 and extend in the radial direction of the fixed portion 31 so that the spring pieces 32 are arranged radially around the fixed portion 31 (at intervals of 90 ° in the circumferential direction). ) Is arranged. These spring pieces 32 are provided at portions where the base end portions are cut out of a part of the outer peripheral portion of the fixing portion 31, and as a whole, are provided along the attachment surface 31 a of the fixing portion 31 to the support body 40. However, as shown in FIG. 10 (c), the mounting surface 31a is not exactly flush with the mounting surface 31a. It is provided with a slope. In other words, when the attachment surface 31a of the fixing portion 31 is brought into contact with the surface of the support body 40, the spring piece 32 is inclined so as to be separated from the surface of the support body 40 toward the tip.
　円弧板状壁３３～３５は、取り付け金具３０の前方に向かって取り付け面３１ａと直交する方向に延びており、各ばね片３２の間に配置されるように、固定部３１を中心に周方向に９０°ずつ間隔をおいて合計４個設けられている。これら４個の円弧板状壁３３～３５のうち、１８０°反対側に設けられる円弧板状壁３３どうし及び円弧板状壁３４，３５が、２個ずつの組をなすように、固定部３１の中心Ｏ１から異なる二つの半径の円周上に配置されている。具体的には、指示部３７の矢印の向きに対向する一組の円弧板状壁３４，３５は、図１０（ｂ）に二点鎖線で示す円Ｃ１の円周上に配置されるが、これらと直交する方向に対向する他の一組の円弧板状壁３３は、先の円弧板状壁３４，３５よりも小さい半径の円弧状に形成されている。このうち、後述するように、半径の大きい一組の円弧板状壁３４，３５は、筐体１０の取り付け部１２の筒状壁１５の内周面よりわずかに小さい半径に形成され、半径の小さい一組の円弧板状壁３３は、筒状壁１５のリブ１６の先端（内周端）により形成される円の半径よりわずかに小さい半径に形成される。なお、円弧板状壁３３は、周方向長さが同じに設定されているが、円弧板状壁３４，３５は、円弧板状壁３４が円弧板状壁３５より周方向長さが大きく設定されている。 The arcuate plate-like walls 33 to 35 extend in the direction perpendicular to the attachment surface 31a toward the front of the attachment fitting 30, and are arranged in the circumferential direction around the fixed portion 31 so as to be disposed between the spring pieces 32. A total of four are provided at intervals of 90 °. Among these four arc plate-like walls 33 to 35, the fixing portion 31 is arranged so that the arc plate-like walls 33 and the arc plate- like walls 34, 35 provided on the opposite sides of 180 ° form a set of two. They are arranged from the center O 1 of the two different radii of the circumference. Specifically, the pair of arcuate plate- like walls 34 and 35 facing the direction of the arrow of the instruction unit 37 are arranged on the circumference of a circle C1 indicated by a two-dot chain line in FIG. The other set of arcuate plate-like walls 33 facing each other in a direction perpendicular to these are formed in an arcuate shape having a smaller radius than the previous arcuate plate- like walls 34 and 35. Among these, as will be described later, the pair of arcuate plate- like walls 34 and 35 having a large radius are formed to have a radius slightly smaller than the inner peripheral surface of the cylindrical wall 15 of the mounting portion 12 of the housing 10. The small pair of arcuate plate-like walls 33 is formed to have a radius slightly smaller than the radius of the circle formed by the tips (inner peripheral ends) of the ribs 16 of the cylindrical wall 15. The circular arc plate-like wall 33 is set to have the same circumferential length, but the circular arc plate- like walls 34 and 35 are set to have a longer circumferential length than the circular arc plate-like wall 35. Has been.
　そして、この半径の小さい円弧板状壁３３、つまり、指示部３７の矢印の向きに直交する方向に配置される２個の円弧板状壁３３の先端に爪部３６がそれぞれ設けられている。これら爪部３６は、円弧板状壁３３の先端部を折り曲げることにより、円弧板状壁３３の外周部に取り付け面３１ａと平行に半径方向外方に向けて一体に形成されている。この場合、両爪部３６は、平板状ではなく、円周方向に湾曲した状態に形成され、その上面（ばね片３２側に向けた表面）が凸状面３６ａに形成されている。なお、これら爪部３６の先端（外周端）は、前述した半径の大きい円弧板状壁３４，３５により形成される円Ｃ１の外側に突出しないように、その円Ｃ１よりもわずかに半径方向内方位置に配置される。
　このように形成された取り付け金具３０において、本発明では、大きい半径の円弧板状壁３４，３５をガイド壁とし、小さい半径の円弧板状壁３３を壁部と称している。以降、これらを区別する場合には、ガイド壁３４，３５、壁部３３と称す。また、各ばね片３２は、図１０（ｂ）に示すように、ガイド壁３４，３５により形成される円Ｃ１よりも半径方向外側位置まで延びて形成されている。 Claw portions 36 are respectively provided at the tips of the arc plate-like walls 33 having a small radius, that is, the two arc plate-like walls 33 arranged in a direction orthogonal to the direction of the arrow of the indication portion 37. The claw portions 36 are integrally formed on the outer peripheral portion of the circular arc plate-like wall 33 in a radially outward direction parallel to the attachment surface 31a by bending the tip portion of the circular arc plate-like wall 33. In this case, both the claw portions 36 are not formed in a flat plate shape, but are formed in a curved state in the circumferential direction, and an upper surface thereof (a surface facing the spring piece 32 side) is formed on the convex surface 36a. Note that the tips (outer peripheral ends) of the claw portions 36 are slightly inward in the radial direction from the circle C1 so as not to protrude outside the circle C1 formed by the arc-shaped plate walls 34 and 35 having a large radius described above. It is arranged in the direction.
In the mounting bracket 30 thus formed, in the present invention, the arc plate- like walls 34 and 35 having a large radius are referred to as guide walls, and the arc plate-like wall 33 having a small radius is referred to as a wall portion. Hereinafter, when these are distinguished, they are referred to as guide walls 34 and 35 and a wall portion 33. Further, as shown in FIG. 10B, each spring piece 32 is formed to extend to a radially outer position than a circle C1 formed by the guide walls 34 and 35.
　筐体１０の取り付け部１２の端部は、前述したように円錐台状に形成され、筒状壁１５を有している。この筒状壁１５の内周面は、取り付け金具３０におけるガイド壁（大きい半径の円弧板状壁）３４，３５によって形成される円Ｃ１よりわずかに大きい半径に形成され、その筒状壁１５内にガイド壁３４，３５が挿入し得るようになっている。
　筒状壁１５の内周部には、半径方向内方に突出する複数のリブ１６が軸方向に平行に形成されている。そして、これらリブ１６が形成されていない部分が、図示例の場合、周方向に間隔をおいて４箇所形成されている。そのうち、１８０°対向する２個ずつが組をなしており、一つの組が取り付け金具３０のガイド壁３４，３５を導入する第１ガイド部１７，１８、他の一組が爪部３６を導入する第２ガイド部１９とされている。この場合、第１ガイド部１７，１８は、取り付け金具３０のガイド壁３４，３５のそれぞれの周方向長さよりも十分に大きい周方向長さを有しているが、両者の周方向長さは異なっており、周方向長さの小さいガイド壁３５を案内する第１ガイド部１８には、周方向長さの大きいガイド壁３４を導入することはできない大きさに設定されている。これにより、取り付け金具３０に対する取り付け部１２の周方向の向きを規定して、誤った取り付け姿勢となることを防止することができる。一方、第２ガイド部１９は、取り付け金具３０の爪部３６を若干の余裕を持って導入し得る程度の周方向長さに設定されている。 The end portion of the attachment portion 12 of the housing 10 is formed in a truncated cone shape as described above, and has a cylindrical wall 15. The inner peripheral surface of the cylindrical wall 15 is formed to have a radius slightly larger than the circle C1 formed by the guide walls (large radius arcuate plate-like walls) 34 and 35 in the mounting bracket 30, The guide walls 34 and 35 can be inserted into the door.
A plurality of ribs 16 projecting inward in the radial direction are formed on the inner peripheral portion of the cylindrical wall 15 in parallel with the axial direction. And in the example of illustration, the part in which these ribs 16 are not formed is formed in four places at intervals in the circumferential direction. Among them, two each facing 180 ° form a set, one set introduces the first guide portions 17 and 18 for introducing the guide walls 34 and 35 of the mounting bracket 30, and the other set introduces the claw portion 36. The second guide portion 19 is used. In this case, the first guide portions 17 and 18 have circumferential lengths sufficiently larger than the circumferential lengths of the guide walls 34 and 35 of the mounting bracket 30, but the circumferential lengths of both of them are The first guide portion 18 that guides the guide wall 35 having a small length in the circumferential direction is set to a size in which the guide wall 34 having a large circumferential length cannot be introduced. Thereby, the direction of the circumferential direction of the attachment part 12 with respect to the attachment metal fitting 30 can be prescribed | regulated, and it can prevent becoming an incorrect attachment attitude | position. On the other hand, the 2nd guide part 19 is set to the circumferential direction length which can introduce the nail | claw part 36 of the attachment metal fitting 30 with some margins.
　また、リブ１６は、これらガイド部１７～１９を避けて設けられており、各リブ１６の高さは同一に設定され、これらリブ１６の先端（内周端）により形成される円Ｃ２（図８の二点鎖線参照）の半径は、取り付け金具３０の爪部３６を有する円弧板状壁（壁部）３３の外周面の半径よりわずかに大きい寸法に設定されている。これらリブ１６の中で第１ガイド部１７，１８を形成している一対のリブ１６のうちの一方のリブは、円弧板状壁３４，３５を導入する際に、円弧板状壁３４，３５の側縁に接近した位置に設けられており、後述するように、爪部３６と突起部２１との係止状態を解除する際のストッパ壁を構成している。図１及び図２等では、このストッパ壁を符号１６Ａで表示して、他のリブ１６と区別するが、以降、両者を特に区別しない場合は、リブ１６と称することとする。 The ribs 16 are provided so as to avoid these guide portions 17 to 19, and the heights of the ribs 16 are set to be the same, and a circle C2 formed by the tips (inner peripheral ends) of the ribs 16 (see FIG. 8 is set to a size slightly larger than the radius of the outer peripheral surface of the circular arc plate-like wall (wall portion) 33 having the claw portion 36 of the mounting bracket 30. Of the ribs 16, one of the pair of ribs 16 forming the first guide portions 17, 18 has the arc plate- like walls 34, 35 when the arc plate- like walls 34, 35 are introduced. As will be described later, a stopper wall is formed when the locking state between the claw portion 36 and the protruding portion 21 is released. In FIG. 1 and FIG. 2 and the like, this stopper wall is indicated by reference numeral 16A and is distinguished from other ribs 16. However, hereinafter, when not particularly distinguished from each other, they will be referred to as ribs 16.
　また、第２ガイド部１９の側方であって取り付け部１２の端面から所定深さの位置に、突起部２１が半径方向内方に突出して形成されている。この突起部２１は、全体としては筒状壁１５の周方向に延びるように形成され、ガイド部１７～１９に対して直交する方向に形成されているが、筒状壁１５の端面１５ａ側とは反対側の表面が筒状壁１５の周方向に沿って湾曲した円弧の凹状面２１ａに形成されている。この突起部２１の凹状面２１ａは、前述した取り付け金具３０の爪部３６の凸状面３６ａとほぼ同じ曲率に形成されている。この突起部２１は、前述した本体部１１の首振り方向に対して直交する方向にそれぞれ形成されている。言い換えれば、首振り方向をＹ方向とすると、Ｘ方向に対向するように配置されている。 Further, a protruding portion 21 is formed on the side of the second guide portion 19 at a predetermined depth from the end face of the mounting portion 12 so as to protrude radially inward. The projecting portion 21 is formed so as to extend in the circumferential direction of the cylindrical wall 15 as a whole, and is formed in a direction orthogonal to the guide portions 17 to 19. The opposite surface is formed on an arcuate concave surface 21 a that is curved along the circumferential direction of the cylindrical wall 15. The concave surface 21a of the projection 21 is formed with substantially the same curvature as the convex surface 36a of the claw 36 of the mounting bracket 30 described above. The protrusions 21 are formed in directions orthogonal to the swinging direction of the main body 11 described above. In other words, when the swinging direction is the Y direction, they are arranged to face the X direction.
　この場合、筒状壁１５の端面１５ａから突起部２１の凹状面２１ａの頂部までの距離Ｈ１（図９参照）は、取り付け金具３０の固定部３１の表面（取り付け面３１ａに対して反対側の面）から爪部３６の凸状面３６ａの頂部までの距離Ｈ２（図１０（ａ）参照）より若干大きい寸法（Ｈ１＞Ｈ２）、つまり、突起部２１の凹状面２１ａが爪部３６の凸状面３６ａに接触したときに、端面１５ａが接触しているばね片３２を弾性変形させ得る寸法に設定されている。そして、取り付け金具３０の爪部３６を筒状壁１５の第２ガイド部１９に沿って導入した後に、筒状壁１５をその軸心Ｏ２周りに回動することにより、爪部３６の凸状面３６ａが突起部２１の凹状面２１ａの端部を乗り越えた後に凹状面２１ａに係止するようになっている。 In this case, the distance H1 (see FIG. 9) from the end surface 15a of the cylindrical wall 15 to the top of the concave surface 21a of the projection 21 is the surface of the fixing portion 31 of the mounting bracket 30 (on the opposite side to the mounting surface 31a). Surface) to the top of the convex surface 36a of the claw portion 36 (see FIG. 10A) (H1> H2), that is, the concave surface 21a of the projecting portion 21 is the convexity of the claw portion 36. The size is set such that the spring piece 32 in contact with the end face 15a can be elastically deformed when it comes into contact with the surface 36a. Then, after the claw portion 36 of the mounting bracket 30 is introduced along the second guide portion 19 of the cylindrical wall 15, the cylindrical wall 15 is rotated around its axis O 2 , thereby causing the projection of the claw portion 36. After the shape surface 36a gets over the end portion of the concave surface 21a of the protruding portion 21, it engages with the concave surface 21a.
　また、この突起部２１には、その凹状面２１ａとは反対側で筒状壁１５の端面１５ａまで延びる複数本のリブ（本発明の補強壁）１６Ｂと、凹状面２１ａとの間で爪部３６を配置可能な溝状の凹部を形成するようにＬ字状に屈曲した補助リブ２３とが筒状壁１５の内方に突出して一体に形成されている。これらリブ１６Ｂ、補助リブ２３の突出高さも、前述したリブ１６の突出高さと同じに設定される。また、突起部２１に一体のリブ１６Ｂを他のリブ１６と区別するため補強壁１６Ｂとする。 Further, the protrusion 21 has a claw between the concave surface 21a and a plurality of ribs (reinforcing walls of the present invention) 16B extending to the end surface 15a of the cylindrical wall 15 on the opposite side to the concave surface 21a. An auxiliary rib 23 bent in an L-shape so as to form a groove-like recess in which 36 can be disposed protrudes inward of the cylindrical wall 15 and is integrally formed. The protruding heights of the ribs 16B and the auxiliary ribs 23 are also set to be the same as the protruding heights of the ribs 16 described above. In addition, the rib 16B integrated with the protruding portion 21 is a reinforcing wall 16B in order to distinguish it from the other ribs 16.
　このように構成した筐体１０と取り付け金具３０とは、図１に示すように、支持体４０の表面に取り付け金具３０を固定し、その取り付け金具３０に筐体１０を矢印で示すように取り付けることにより、取り付け金具３０を介して筐体１０を支持体４０に固定することができる。以下に、支持体４０が壁である場合の取り付け手順を詳細に説明する。
　まず、取り付け金具３０の取り付け面３１ａを支持体４０の表面に当接し、孔部３８からねじを挿入して取り付け金具３０を支持体４０に固定する。このとき、指示部３７の矢印が下（Ｙ方向の下方）を向くように配置する。
　この取り付け金具３０を支持体４０の表面に固定した状態とすると、円弧板状壁３３～３５が支持体４０の表面から直角に突出し、ばね片３２が先端に向かうにしたがって漸次支持体４０の表面から離れるように傾斜した状態に配置される。 As shown in FIG. 1, the casing 10 and the mounting bracket 30 configured as described above fix the mounting bracket 30 to the surface of the support 40 and attach the casing 10 to the mounting bracket 30 as indicated by an arrow. Thus, the housing 10 can be fixed to the support body 40 via the mounting bracket 30. Below, the attachment procedure in case the support body 40 is a wall is demonstrated in detail.
First, the mounting surface 31 a of the mounting bracket 30 is brought into contact with the surface of the support 40, and a screw is inserted from the hole 38 to fix the mounting bracket 30 to the support 40. At this time, it arrange | positions so that the arrow of the instruction | indication part 37 may face down (downward of a Y direction).
Assuming that the mounting bracket 30 is fixed to the surface of the support 40, the arcuate plate-like walls 33 to 35 protrude perpendicularly from the surface of the support 40, and the surface of the support 40 gradually increases as the spring piece 32 moves toward the tip. It is arrange | positioned in the state inclined so that it may leave | separate.
　次に、この取り付け金具３０に筐体１０を固定する。このとき、筐体１０の取り付け部１２における第１ガイド部１７，１８を取り付け金具３０の円弧板状壁３４，３５に位置合わせし、第２ガイド部１９を爪部３６に位置合わせした状態で筐体１０の取り付け部１２における筒状壁１５を取り付け金具３０に被せるように支持体４０の表面に向けて接近させ、取り付け金具３０の円弧板状壁３３～３５及び爪部３６を筒状壁１５内に導入する（ｚ方向が導入方向である）。この場合、取り付け金具３０の指示部３７の矢印の向きと、筐体１０における取り付け部１２の第１ガイド部１７，１８の配置とを確認することにより、上下方向（Ｙ方向）を設定して、取り付け金具３０に筐体１０を接近させる。前述したように、取り付け金具３０の円弧板状壁３４，３５は周方向長さが異なり、取り付け部１２の第１ガイド部１７，１８も周方向長さが異なっているので、これらの向きを誤って取り付けることが防止される。
　なお、筒状壁１５の内面には、図１及び図９に示すように、突起部２１と、これに一体に形成したＬ字状の補助リブ２３とにより、溝状の開口が第２ガイド部１９に向けて形成されていることが目視できるので、取り付け時に爪部３６を導入する第２ガイド部１９の位置の確認も容易である。
　この取り付け金具３０の円弧板状壁３３～３５及び爪部３６を筒状壁１５内に導入した状態を取り付け金具３０側から視た図が図２である。 Next, the housing 10 is fixed to the mounting bracket 30. At this time, the first guide portions 17 and 18 in the mounting portion 12 of the housing 10 are aligned with the arcuate plate- like walls 34 and 35 of the mounting bracket 30, and the second guide portion 19 is aligned with the claw portion 36. The cylindrical wall 15 in the mounting portion 12 of the housing 10 is brought close to the surface of the support 40 so as to cover the mounting bracket 30, and the arcuate plate-shaped walls 33 to 35 and the claw portion 36 of the mounting bracket 30 are connected to the cylindrical wall. 15 (z direction is the introduction direction). In this case, the vertical direction (Y direction) is set by confirming the direction of the arrow of the indication portion 37 of the mounting bracket 30 and the arrangement of the first guide portions 17 and 18 of the mounting portion 12 in the housing 10. Then, the housing 10 is brought close to the mounting bracket 30. As described above, the arcuate plate- like walls 34 and 35 of the mounting bracket 30 have different circumferential lengths, and the first guide portions 17 and 18 of the mounting portion 12 have different circumferential lengths. Incorrect mounting is prevented.
As shown in FIGS. 1 and 9, a groove-shaped opening is formed on the inner surface of the cylindrical wall 15 by a protrusion 21 and an L-shaped auxiliary rib 23 formed integrally therewith. Since it can be visually observed that it is formed toward the portion 19, it is easy to confirm the position of the second guide portion 19 that introduces the claw portion 36 at the time of attachment.
FIG. 2 shows a state in which the arcuate plate-like walls 33 to 35 and the claw portions 36 of the mounting bracket 30 are introduced into the cylindrical wall 15 as viewed from the mounting bracket 30 side.
　このようにして、取り付け部１２における筒状壁１５の端面１５ａに取り付け金具３０のばね片３２が当接したら、その端面１５ａでばね片３２を押圧して弾性変形させることにより、ばね片３２を支持体４０の表面に接触させ、その状態でばね片３２の表面に沿って取り付け部１２の端面１５ａをスライドさせるように筐体１０を軸心Ｏ２を中心として図２の矢印で示すように回動させて図３に示す状態とする。この回動により、第２ガイド部１９に配置されていた爪部３６が筒状壁１５の内周面に沿って移動して、突起部２１の下方に配置する。この突起部２１は、その下面が凹状面２１ａに形成され、一方、爪部３６の上面は凸状面３６ａに形成されていることから、爪部３６が突起部２１の下方に配置される際に、爪部３６の凸状面３６ａの頂部が突起部２１の凹状面２１ａの端部を乗り越えた後に凹状面２１ａに凸状面３６ａが嵌り込む。 In this way, when the spring piece 32 of the mounting bracket 30 comes into contact with the end face 15a of the cylindrical wall 15 in the attachment portion 12, the spring piece 32 is pressed and elastically deformed by pressing the spring piece 32 with the end face 15a. As shown by the arrow in FIG. 2, the housing 10 is brought into contact with the surface of the support 40 and the end surface 15 a of the mounting portion 12 is slid along the surface of the spring piece 32 in this state, with the axis O 2 as the center. Rotate to the state shown in FIG. By this rotation, the claw portion 36 disposed in the second guide portion 19 moves along the inner peripheral surface of the cylindrical wall 15 and is disposed below the projection portion 21. Since the lower surface of the projection 21 is formed as a concave surface 21 a, while the upper surface of the claw portion 36 is formed as a convex surface 36 a, the claw portion 36 is disposed below the projection 21. In addition, the convex surface 36a is fitted into the concave surface 21a after the top of the convex surface 36a of the claw 36 has passed over the end of the concave surface 21a of the protrusion 21.
　このため、凸状面３６ａの頂部が突起部２１の凹状面２１ａの端部を乗り越えるときに、筒状壁１５の端面１５ａに接触しているばね片３２と爪部３６との間隔が広げられ、次いで、凹状面２１ａに凸状面３６ａが嵌り込むときに狭められる。この動作が瞬時に行われるため、操作者の手にはクリック感として伝わり、これにより、操作者は、筐体１０が取り付け金具３０に固定状態となったことがわかる。 For this reason, when the top part of the convex surface 36a gets over the end part of the concave surface 21a of the projection part 21, the space | interval of the spring piece 32 and the nail | claw part 36 which are contacting the end surface 15a of the cylindrical wall 15 is expanded. Then, when the convex surface 36a is fitted into the concave surface 21a, it is narrowed. Since this operation is performed instantaneously, it is transmitted to the operator's hand as a click feeling, so that the operator knows that the housing 10 is fixed to the mounting bracket 30.
　このようにして取り付け金具３０の爪部３６と筐体１０の突起部２１とが固定状態となると、筐体１０が支持体４０の表面に固定され、この固定状態で、本体部１１の首振り方向は上下方向（Ｙ方向）に設置される。
　前述したように、筒状壁１５の端面１５ａから突起部２１の凹状面２１ａの頂部までの距離Ｈ１と、取り付け金具３０の固定部３１の表面（取り付け面３１ａに対して反対側の面）から爪部３６の凸状面３６ａの頂部までの距離Ｈ２とは、Ｈ１＞Ｈ２の関係に設定されているから、この固定状態においては、ばね片３２が弾性変形させられた状態、つまり、突起部２１の凹状面２１ａと爪部３６の凸状面３６ａとがばね片３２の復元力によって押圧力を作用させた状態で接触させられており、強固な固定状態を維持することができる。
　したがって、爪部３６と突起部２１との接触部分にガタが生じにくく、スピーカ１の筐体１０として共振の発生が防止され、優れた音響特性を維持することができる。 When the claw portion 36 of the mounting bracket 30 and the protruding portion 21 of the housing 10 are in a fixed state in this way, the housing 10 is fixed to the surface of the support body 40, and in this fixed state, the main body 11 swings. The direction is set in the vertical direction (Y direction).
As described above, from the distance H1 from the end surface 15a of the cylindrical wall 15 to the top of the concave surface 21a of the projection 21 and the surface of the fixing portion 31 of the mounting bracket 30 (surface opposite to the mounting surface 31a). Since the distance H2 to the top of the convex surface 36a of the claw portion 36 is set to a relationship of H1> H2, in this fixed state, the spring piece 32 is elastically deformed, that is, the protruding portion. The concave surface 21a of 21 and the convex surface 36a of the claw part 36 are brought into contact with each other in a state where a pressing force is applied by the restoring force of the spring piece 32, so that a strong fixed state can be maintained.
Therefore, rattling is unlikely to occur at the contact portion between the claw portion 36 and the protruding portion 21, and the occurrence of resonance is prevented as the housing 10 of the speaker 1, and excellent acoustic characteristics can be maintained.
　一方、固定状態とした筐体１０を支持体４０の表面から取り外す場合は、筐体１０を取り付け時とは逆方向に回動させることにより、ばね片３２に当接している取り付け部１２の端面１５ａをばね片３２に沿ってスライドさせ、爪部３６と突起部２１との固定状態を解除した後、第１ガイド部１７，１８及び第２ガイド部１９に沿って円弧板状壁３４，３５及び爪部３６を引き上げれば、筐体１０を取り付け金具３０から離脱することができる。その後、必要に応じて、取り付け金具３０を支持体４０から外せばよい。 On the other hand, when removing the fixed housing 10 from the surface of the support 40, the end surface of the attachment portion 12 that is in contact with the spring piece 32 is rotated by rotating the housing 10 in the direction opposite to that at the time of attachment. 15 a is slid along the spring piece 32 to release the fixed state between the claw portion 36 and the projection 21, and then the arcuate plate- like walls 34 and 35 along the first guide portions 17 and 18 and the second guide portion 19. When the claw portion 36 is pulled up, the housing 10 can be detached from the mounting bracket 30. Then, what is necessary is just to remove the attachment metal fitting 30 from the support body 40 as needed.
　この取り外し操作において、爪部３６を突起部２１との固定状態から解除する際の勢いにより操作者の意図以上に筐体１０が回動しようとするが、第１ガイド部１７，１８の側方を規制するストッパ壁１６Ａが設けられていることにより、円弧板状壁３４，３５の側縁がストッパ壁１６Ａに当接して円弧板状壁３４，３５が第１ガイド部１７，１８内で確実に停止される。したがって、筐体１０を支持体４０の表面から離間するように引き上げれば、取り付け金具３０から離脱することができる。 In this detaching operation, the casing 10 tries to turn more than the operator's intention due to the momentum when the claw portion 36 is released from the fixed state with the projection 21, but the side of the first guide portions 17, 18 By providing the stopper wall 16A for regulating the arc, the side edges of the arcuate plate- like walls 34 and 35 abut against the stopper wall 16A so that the arcuate plate- like walls 34 and 35 are securely in the first guide portions 17 and 18. To be stopped. Therefore, if the casing 10 is lifted away from the surface of the support body 40, it can be detached from the mounting bracket 30.
　以上説明したように、この筐体取り付け構造では、取り付け金具３０を壁等の支持体４０に固定し、その取り付け金具３０に筐体１０を被せるようにして取り付け金具３０の爪部３６をガイド部１７～１９により筐体１０内に導入し、ばね片３２を筐体１０の端面１５ａで押圧するようにして弾性変形させながら、筐体１０をスライドして爪部３６の表面に突起部２１を押圧状態に接触することにより、筐体１０を取り付け金具３０を介して支持体４０に固定することができる。
　この筐体取り付け構造において、筐体１０を固定するための爪部３６及び突起部２１とは別に取り付け金具３０にばね片３２を設け、そのばね片３２を取り付け面３１ａに沿って突出するように延びる形状としたので、ばね片３２を爪部３６よりも長く形成して十分なばね作用を生じさせることができる。このため、このばね片３２の弾性力により、爪部３６と突起部２１との押圧接触状態を強固にすることができ、筐体１０を支持体４０に強固に固定することができる。また、この固定状態においても、ばね片３２の弾性力が作用しているので、爪部３６と突起部２１との接触部分にガタが生じにくく、筐体１０がスピーカボックス等の音響機器用の筐体１０である場合でも、共振の発生を防止し、優れた音響特性を維持することができる。
　しかも、筐体１０のガイド部１７～１９に円弧板状壁３４，３５及び爪部３６を導入して、ばね片３２の表面に筐体１０の端面１５ａを当接させ、その状態でスライドすることにより、爪部３６と突起部２１とを押圧状態に接触して固定することができるので、取り付け金具３０への筐体１０の取り付け作業も容易である。 As described above, in this case mounting structure, the mounting bracket 30 is fixed to the support 40 such as a wall, and the claw portion 36 of the mounting bracket 30 is guided by the guide portion so that the casing 10 is covered with the mounting bracket 30. 17 to 19 is introduced into the housing 10 and the spring piece 32 is elastically deformed so as to be pressed by the end face 15a of the housing 10, while the housing 10 is slid to project the protrusion 21 on the surface of the claw portion 36. By contacting the pressed state, the housing 10 can be fixed to the support body 40 via the mounting bracket 30.
In this housing mounting structure, a spring piece 32 is provided on the mounting bracket 30 separately from the claw portion 36 and the protrusion 21 for fixing the housing 10 so that the spring piece 32 protrudes along the mounting surface 31a. Because of the extended shape, the spring piece 32 can be formed longer than the claw portion 36 to produce a sufficient spring action. For this reason, the pressing contact state between the claw portion 36 and the protruding portion 21 can be strengthened by the elastic force of the spring piece 32, and the housing 10 can be firmly fixed to the support body 40. Further, even in this fixed state, the elastic force of the spring piece 32 is acting, so that the contact portion between the claw portion 36 and the projection portion 21 is less likely to be loose, and the housing 10 is used for an audio device such as a speaker box. Even in the case 10, it is possible to prevent the occurrence of resonance and maintain excellent acoustic characteristics.
In addition, the arc plate- like walls 34 and 35 and the claw portion 36 are introduced into the guide portions 17 to 19 of the housing 10 so that the end face 15a of the housing 10 is brought into contact with the surface of the spring piece 32 and slides in that state. Thereby, since the nail | claw part 36 and the projection part 21 can be fixed in contact with a press state, the attachment operation | work of the housing | casing 10 to the attachment metal fitting 30 is also easy.
　また、突起部２１と爪部３６との接触部分には、凹状面２１ａと該凹状面２１ａに嵌り込む凸状面３６ａとが、これら凹状面２１ａ及び凸状面３６ａの表面がスライド方向に沿って変化するように形成されているので、筐体１０のガイド部１９に取り付け金具３０の爪部３６を導入した後、スライドさせて爪部３６の表面に突起部２１を接触する際に、凸状面３６ａの頂部を凹状面２１ａの端部が乗り上げた後に凸状面３６ａが凹状面２１ａに嵌り込む。このため、凸状面３６ａの頂部と凹状面２１ａの端部とが乗り上げる前後で操作者の手にクリック感が伝わり、固定状態となったことを容易に確認することができる。また、凹状面２１ａに凸状面３６ａが嵌り込んだ状態で固定されるので、スライド方向への移動が規制され、固定状態が不用意に解除されることが防止される。 Further, a concave surface 21a and a convex surface 36a that fits into the concave surface 21a are provided at the contact portion between the projection 21 and the claw portion 36. The surfaces of the concave surface 21a and the convex surface 36a are along the sliding direction. When the projection 21 is brought into contact with the surface of the claw 36 by sliding the claw 36 of the mounting bracket 30 into the guide 19 of the housing 10, the projection 21 is projected. The convex surface 36a fits into the concave surface 21a after the end of the concave surface 21a rides on the top of the convex surface 36a. For this reason, a click feeling is transmitted to the operator's hand before and after the top of the convex surface 36a and the end of the concave surface 21a ride on, and it can be easily confirmed that the fixed state has been achieved. Moreover, since it fixes with the convex surface 36a fitting in the concave surface 21a, the movement to a slide direction is controlled and a fixed state is prevented from being cancel | released carelessly.
　また、筐体１０が横断面円形の筒状壁１５を有し、取り付け金具３０には、ばね片３２が放射状に複数設けられるとともに、壁部（円弧板状壁）３３がばね片３２の間に配置されるように複数設けられており、端面は筒状壁１５の端面１５ａであり、壁部３３のそれぞれに対応してガイド部１９及び突起部２１が筒状壁１５の内面に形成されているので、取り付け金具３０の爪部３６をガイド部１９に沿って筒状壁１５内に導入して、筒状壁１５の端面１５ａをばね片３２の表面に接触させた後、筒状壁１５を軸心を中心に回動することにより、爪部３６の表面を突起部２１に押圧状態に接触させることができ、取り付け作業をより容易にすることができる。また、ばね片３２を放射状に設けるとともに、壁部３３も複数設けているから、筒状壁１５を安定して固定することができる。 The casing 10 has a cylindrical wall 15 having a circular cross section, and the mounting bracket 30 is provided with a plurality of spring pieces 32 radially, and a wall portion (arc plate-like wall) 33 is formed between the spring pieces 32. The end surface is an end surface 15 a of the cylindrical wall 15, and the guide portion 19 and the protruding portion 21 are formed on the inner surface of the cylindrical wall 15 corresponding to each of the wall portions 33. Therefore, after the claw portion 36 of the mounting bracket 30 is introduced into the cylindrical wall 15 along the guide portion 19 and the end surface 15a of the cylindrical wall 15 is brought into contact with the surface of the spring piece 32, the cylindrical wall By rotating 15 about the axis, the surface of the claw portion 36 can be brought into contact with the protruding portion 21 in a pressed state, and attachment work can be facilitated. Moreover, since the spring piece 32 is provided radially and the wall part 33 is also provided with two or more, the cylindrical wall 15 can be fixed stably.
　さらに、爪部３６の表面に突起部２１が押圧状態に接触すると、突起部２１は爪部３６に押圧されて接触部分とは反対側に倒れようとするが、突起部２１における爪部３６との接触部分とは反対側に逆方向に延びる補強壁１６Ｂが突起部２１と一体に設けられているので、突起部２１が倒れることが防止され、爪部３６を強固に係止することができる。 Further, when the projection 21 comes into contact with the surface of the claw portion 36 in a pressed state, the projection 21 is pressed by the claw portion 36 and tends to fall to the opposite side of the contact portion. Since the reinforcing wall 16B extending in the opposite direction to the opposite side of the contact portion is provided integrally with the protruding portion 21, the protruding portion 21 is prevented from falling down and the claw portion 36 can be firmly locked. .
　また、壁部３３は取り付け面３１ａと交差する方向に延びて、先端部に爪部３６を有しているため、例えば壁部が平坦な帯板状であると爪部３６の表面に突起部２１が押圧状態に接触する際に壁部が弾性変形し易いため、爪部３６に対する押圧力が低減するおそれがあるが、壁部３３はスライド方向に湾曲した湾曲板状に形成されていることから、弾性変形しにくく、したがって、爪部３６への押圧力を有効に作用させて、固定状態を安定することができる。 Moreover, since the wall part 33 is extended in the direction which cross | intersects the attachment surface 31a, and has the nail | claw part 36 in the front-end | tip part, if a wall part is flat strip shape, for example, it is a projection part on the surface of the nail | claw part 36 Since the wall portion is easily elastically deformed when 21 is in contact with the pressed state, the pressing force against the claw portion 36 may be reduced, but the wall portion 33 is formed in a curved plate shape curved in the sliding direction. Therefore, it is difficult to be elastically deformed, and therefore the pressing force to the claw portion 36 can be effectively applied to stabilize the fixed state.
　さらに、取り付け金具３０により取り付けた筐体１０を取り外す際は、突起部２１に押圧状態に接触されている爪部３６をスライドさせて突起部２１から離脱した後にガイド部１９に沿って引き抜くことが行われるが、突起部２１とは反対方向への爪部３６の移動を規制するストッパ壁がないと、爪部３６を突起部２１から離脱する際の勢いによって爪部３６がガイド部１９を超えてしまうおそれがある。本実施形態では、図１等に示すように、ガイド壁３４，３５を案内する第１ガイド部１７，１８の側部を構成するようにストッパ壁１６Ａを形成し、そのストッパ壁１６Ａにガイド壁３４，３５を当接させて、突起部２１とは反対方向への爪部３６の移動を規制しているので、爪部３６をガイド部１９から円滑に引き抜くことができる。 Furthermore, when removing the housing 10 attached by the mounting bracket 30, the claw portion 36 that is in contact with the protruding portion 21 may be slid and removed from the protruding portion 21 and then pulled out along the guide portion 19. However, if there is no stopper wall that restricts the movement of the claw portion 36 in the direction opposite to the projection portion 21, the claw portion 36 exceeds the guide portion 19 due to the momentum when the claw portion 36 is detached from the projection portion 21. There is a risk that. In this embodiment, as shown in FIG. 1 and the like, the stopper wall 16A is formed so as to constitute the side portions of the first guide portions 17 and 18 for guiding the guide walls 34 and 35, and the guide wall is formed on the stopper wall 16A. Since the movement of the claw portion 36 in the direction opposite to the protruding portion 21 is restricted by abutting 34, 35, the claw portion 36 can be smoothly pulled out from the guide portion 19.
　なお、本発明は、上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
　例えば、ストッパ壁１６Ａを第１ガイド部１７，１８の側方を規制するものとして形成したが、第２ガイド部１９において突起部２１とは反対側の側部を構成するように、第２ガイド部１９の側方を規制するものとして形成し、突起部２１との固定状態を解除した際に、そのストッパ壁に爪部３６が当接するようにしてもよく、爪部３６を突起部２１から離脱してガイド部１９に配置したときに取り付け金具３０の一部を当接するようにストッパ壁が配置してあればよい。 In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the stopper wall 16A is formed to restrict the side of the first guide parts 17 and 18, but the second guide 19 is configured so as to constitute a side part opposite to the protruding part 21 in the second guide part 19. It is formed so as to restrict the side of the portion 19, and the claw portion 36 may come into contact with the stopper wall when the fixed state with the projection portion 21 is released. It is only necessary that the stopper wall be disposed so that a part of the mounting bracket 30 is brought into contact with the mounting bracket 30 when it is detached and disposed on the guide portion 19.
