Description

本発明は吸音性能に優れた間仕切り装置に関する。 The present invention relates to a partition device having excellent sound absorption performance.

空間を適当な広さに仕切るための間仕切り装置には吸音性能が求められることがある。例えば特許文献1にはパネルの表面材に複数の穴を設け、表面材の裏側に吸音材を貼り付けた間仕切り装置が開示されている。
しかし、パネルの素材として透明なガラスや樹脂等を用いる場合、内部の吸音材が外部から見えると透光性・意匠性が低下するという問題がある。
そこで、特許文献2には前後をガラス板で挟まれた中央空間部と、床レールの周囲の周辺空間部とを区画する区画板を備えており、区画板に複数の貫通穴を形成すると共に周辺空間部に吸音材を充填したダブルガラスパネル装置が開示されている。この装置の場合、外部で発生した音によりガラス板が振動して空気の疎密波（振動）が生じる。この振動は中央空間部から区画板の貫通孔を通過して周辺空間部内の吸音材に対して垂直方向から入射し、吸収される。また、中央空間部には吸音材が存在しないので透光性・意匠性は維持される。なお、同様の技術は特許文献3にも開示されている。 Sound absorption performance may be required for the partition device for partitioning the space to an appropriate size. For example, Patent Document 1 discloses a partition device in which a plurality of holes are provided in the surface material of a panel and a sound absorbing material is attached to the back side of the surface material.
However, when transparent glass, resin, or the like is used as the material of the panel, there is a problem that the translucency and designability are deteriorated when the sound absorbing material inside is visible from the outside.
Therefore, Patent Document 2 includes a partition plate for partitioning a central space portion sandwiched between front and rear glass plates and a peripheral space portion around the floor rail, and forms a plurality of through holes in the partition plate. A double glass panel device in which a sound absorbing material is filled in a peripheral space is disclosed. In the case of this device, the glass plate vibrates due to the sound generated from the outside, and a dense wave (vibration) of air is generated. This vibration passes through the through hole of the partition plate from the central space portion, is incident on the sound absorbing material in the peripheral space portion from the vertical direction, and is absorbed. Further, since there is no sound absorbing material in the central space, the translucency and design are maintained. A similar technique is also disclosed in Patent Document 3.

上記特許文献2及び3に開示された技術ではいずれも空気の振動は区画板の貫通孔を通過して吸音材に対して垂直に入射するものであるが、吸音性能は必ずしも充分とは言えず、より高い吸音性能を持つ間仕切り装置が求められている。 In all of the techniques disclosed in Patent Documents 2 and 3, the vibration of air passes through the through hole of the partition plate and is vertically incident on the sound absorbing material, but the sound absorbing performance is not always sufficient. , There is a demand for a partition device with higher sound absorption performance.

本発明はこのような問題を考慮して、吸音性能に優れた間仕切り装置を提供することを課題とする。 In consideration of such a problem, an object of the present invention is to provide a partition device having excellent sound absorption performance.

本発明の間仕切り装置は、前後に間隔を空けて配置される少なくとも2枚の透明性を有するパネルと、前記パネルの上端を支持する上桟及び天井レールと、前記パネルの下端を支持する下桟及び床レールと、前後の前記パネルと前記上桟と前記下桟とによって前後及び上下を区画されて成る空間部とを備える間仕切り装置において、前記上桟及び／又は前記下桟に取り付けられてその内部に吸音材を格納する格納部を備えており、前記格納部の前後の側面に空隙から成る振動導入路を備えることを特徴とする。
また、前記格納部のうち前記空間部と接する面に複数の貫通穴を備えることを特徴とする。
また、前記振動導入路が前記空間部から連続することを特徴とする。 The partitioning device of the present invention includes at least two transparent panels arranged at a distance from each other in the front-rear direction, an upper rail and a ceiling rail that support the upper end of the panel, and a lower rail that supports the lower end of the panel. And a floor rail, and a partition device including a front and rear panel, an upper rail, and a space portion defined by the upper rail and the lower rail, which are attached to the upper rail and / or the lower rail. A storage unit for storing the sound absorbing material is provided inside, and a vibration introduction path formed of a gap is provided on the front and rear side surfaces of the storage unit.
Further, it is characterized in that a plurality of through holes are provided on the surface of the storage portion that is in contact with the space portion.
Further, the vibration introduction path is continuous from the space portion.

本発明では空間部内の空気の振動の一部は振動導入路を通って格納部の側面に至る。これにより格納部の側面が振動し、この振動の影響を受けて格納部内の空気が振動し、吸音材により吸収される。このように空気の振動が垂直方向（上下方向）から吸音材に至るだけでなく、水平方向（前後方向）からも吸音材に至るので吸音性能をより高めることができる。
格納部のうち空間部と接する面は大面積となるので、この面に貫通穴を開けることにすれば空間部内の空気の振動を効率よく格納部内に導くことができるので吸音性能をより高めることができる。
また、振動導入路を空間部から連続させることにより空間部内の空気の振動を速やかに格納部の側面まで伝達させることができるので吸音性能をより高めることができる。 In the present invention, a part of the vibration of the air in the space portion reaches the side surface of the storage portion through the vibration introduction path. As a result, the side surface of the storage portion vibrates, and the air inside the storage portion vibrates under the influence of this vibration and is absorbed by the sound absorbing material. In this way, the vibration of the air reaches not only the sound absorbing material from the vertical direction (vertical direction) but also from the horizontal direction (front-back direction), so that the sound absorbing performance can be further improved.
Since the surface of the storage part that comes into contact with the space part has a large area, if a through hole is made in this surface, the vibration of the air in the space part can be efficiently guided into the storage part, so that the sound absorption performance can be further improved. Can be done.
Further, by making the vibration introduction path continuous from the space portion, the vibration of the air in the space portion can be quickly transmitted to the side surface of the storage portion, so that the sound absorption performance can be further improved.

［第1の実施の形態］
本発明の間仕切り装置の第1の実施の形態について説明する。
図1及び図2に示すように、間仕切り装置10はパネル20、上桟30、天井レール40、下桟50、床レール60、空間部70、格納部80、吸音材90、振動導入路100等から概略構成される。
パネル20は矩形状の板体であり、透明性を有している。パネル20の素材としては透明性を有するガラス、ポリカーボネートやアクリル等の樹脂等が挙げられるが特にこれらに限定されない。また、本明細書において「透明」には半透明も含まれるものとする。
本実施の形態では前後に間隔を空けて2枚のパネル20を配置しているが、これに限らず前側と後ろ側に各2枚（計4枚）のパネル20を配置してもよい。 [First Embodiment]
A first embodiment of the partition device of the present invention will be described.
As shown in FIGS. 1 and 2, the partition device 10 includes a panel 20, an upper rail 30, a ceiling rail 40, a lower rail 50, a floor rail 60, a space portion 70, a storage portion 80, a sound absorbing material 90, a vibration introduction path 100, etc. It is roughly composed of.
The panel 20 is a rectangular plate and has transparency. Examples of the material of the panel 20 include transparent glass, resins such as polycarbonate and acrylic, and the like, but the material is not particularly limited thereto. Further, in the present specification, "transparent" also includes translucent.
In the present embodiment, two panels 20 are arranged at intervals in the front and rear, but the present invention is not limited to this, and two panels 20 each (four in total) may be arranged on the front side and the rear side.

上桟30、天井レール40、下桟50及び床レール60でパネル20の上端及び下端を支持している。パネル20の支持構造は周知であるため詳細な説明は省略するが、天井面1に天井レール40を天井用アジャスター部材110を介してネジ41で固定し、上桟30は天井用アジャスター金具111を介してネジ固定する。そして、上桟30の前後のパネル嵌合用凹部31に前後のパネル20の上端を嵌め込んでいる。また、床面2に床レール60をネジ61で固定し、下桟50は床用アジャスター部材112を介してネジ固定する。そして、下桟50の前後のパネル嵌合用凹部51に前後のパネル20の下端を嵌め込んでいる。パネル20の左右の端部はスタッド3に接合された縦桟に嵌合しているが、パネル20の左右の端面同士を突き合せた状態で粘着テープ等で連結し、パネル20の連結枚数を増減させることもできる。
空間部70は前後のパネル20と上桟30と下桟50とによって前後及び上下を区画されて成る。前後のパネル20が透明性を有するので一方のパネル20の外部から空間部70を視認できる。 The upper rail 30, ceiling rail 40, lower rail 50, and floor rail 60 support the upper and lower ends of the panel 20. Since the support structure of the panel 20 is well known, detailed explanation is omitted, but the ceiling rail 40 is fixed to the ceiling surface 1 with screws 41 via the ceiling adjuster member 110, and the upper rail 30 has the ceiling adjuster metal fitting 111. Fix it with screws. Then, the upper ends of the front and rear panels 20 are fitted into the front and rear panel fitting recesses 31 of the upper rail 30. Further, the floor rail 60 is fixed to the floor surface 2 with screws 61, and the lower rail 50 is fixed with screws via the floor adjuster member 112. Then, the lower ends of the front and rear panels 20 are fitted into the front and rear panel fitting recesses 51 of the lower rail 50. The left and right ends of the panel 20 are fitted to the vertical rails joined to the stud 3, but the left and right end faces of the panel 20 are abutted against each other and connected with adhesive tape or the like to reduce the number of panels 20 to be connected. It can be increased or decreased.
The space 70 is divided into front and rear and upper and lower by front and rear panels 20, an upper rail 30, and a lower rail 50. Since the front and rear panels 20 are transparent, the space 70 can be visually recognized from the outside of one of the panels 20.

格納部80はその内部に吸音材90を格納するための筐体であり、空間部70の上側と下側に取り付けられる。上側の格納部80はボルト42によって上桟30と共締めされ、下側の格納部80はボルト62によって下桟50と共締めされる。なお、格納部80を空間部70の上側と下側のいずれか一方のみに取り付けることにしてもよい。本実施の形態では床レール60の内部にも吸音材90を充填している。
吸音材90とは音のエネルギーを熱エネルギーに変える性質を持つ材料を指す。本発明の吸音材90としては特に限定されず、グラスウール、ウレタンスポンジその他吸音機能を有する素材、ハニカム構造等の吸音機能を有する構造を備える素材であればよい。
格納部80のうち空間部70と接する面に蓋81を備えている。蓋81を開けた状態で内部に吸音材90を充填し、その後蓋81を閉めることで吸音材90を格納部80に格納する。
本実施の形態では蓋81に複数の貫通穴82を設けてある。貫通穴82を設けることで空間部70内の空気の振動が貫通穴82を通って格納部80の内部に侵入し易くなるので吸音材90による吸音効果を高めることができる。
径を変えた複数種類の貫通穴82（例えば大径、中径及び小径の3種類の穴）を蓋81に設けてもよい。この場合、各貫通穴82の配列は特に限定されず、径が異なる貫通穴82をランダムに配置したり、同一径の貫通穴82を同一直線上に配置したりすればよい。一般的には径が大きくなると吸音率のピーク周波数は高くなる。また同じ径でも数が増えると吸音するピーク周波数が高くなると同時に吸音率も高くなることが知られている。大小異なる径の複数種類の貫通穴を設けることで広範囲な周波数帯域（300Hz〜2,000Hz）で吸音できるようになる。
振動導入路100は格納部80の前後の側面83に形成される空隙である。振動導入路100は空間部70から連続するように、つまり振動導入路100と空間部70とが繋がるように形成するのが好ましい。 The storage portion 80 is a housing for storing the sound absorbing material 90 inside, and is attached to the upper side and the lower side of the space portion 70. The upper storage portion 80 is fastened together with the upper rail 30 by the bolt 42, and the lower storage portion 80 is fastened together with the lower rail 50 by the bolt 62. The storage portion 80 may be attached to only one of the upper side and the lower side of the space portion 70. In the present embodiment, the sound absorbing material 90 is also filled inside the floor rail 60.
The sound absorbing material 90 refers to a material having the property of converting sound energy into heat energy. The sound absorbing material 90 of the present invention is not particularly limited as long as it is glass wool, urethane sponge or other material having a sound absorbing function, or a material having a structure having a sound absorbing function such as a honeycomb structure.
A lid 81 is provided on the surface of the storage portion 80 in contact with the space portion 70. The sound absorbing material 90 is filled inside with the lid 81 open, and then the sound absorbing material 90 is stored in the storage unit 80 by closing the lid 81.
In the present embodiment, the lid 81 is provided with a plurality of through holes 82. By providing the through hole 82, the vibration of the air in the space 70 can easily enter the inside of the storage portion 80 through the through hole 82, so that the sound absorbing effect of the sound absorbing material 90 can be enhanced.
A plurality of types of through holes 82 having different diameters (for example, three types of holes having a large diameter, a medium diameter, and a small diameter) may be provided in the lid 81. In this case, the arrangement of the through holes 82 is not particularly limited, and the through holes 82 having different diameters may be randomly arranged, or the through holes 82 having the same diameter may be arranged on the same straight line. Generally, the larger the diameter, the higher the peak frequency of the sound absorption coefficient. It is also known that as the number of the same diameter increases, the peak frequency of sound absorption increases and the sound absorption coefficient also increases. By providing multiple types of through holes with different diameters, sound can be absorbed in a wide frequency band (300Hz to 2,000Hz).
The vibration introduction path 100 is a gap formed on the front and rear side surfaces 83 of the storage portion 80. It is preferable that the vibration introduction path 100 is formed so as to be continuous from the space portion 70, that is, so that the vibration introduction path 100 and the space portion 70 are connected to each other.

次に本発明の間仕切り装置10が有する吸音機能について説明する。
パネル20の外部で生じた音（空気の振動）の影響を受けてパネル20が振動し、空間部70内の空気が振動する。図3の矢印Aに示すように空間部70内の空気の振動の一部は上下の格納部80の蓋81に設けた貫通穴82を通って吸音材90により吸収され、他の一部は振動導入路100を通って格納部80の側面83に至る。これにより格納部80の側面83が振動し、この振動の影響を受けて格納部80内の空気が振動し、吸音材90により吸収される。
本発明では空間部70内の空気の振動を貫通穴82を通過させて吸音材90で吸収するだけでなく、振動導入路100を利用して格納部80の側面83を振動させることによっても吸収する。空気の振動が垂直方向（上下方向）から吸音材90に至るだけでなく、水平方向（前後方向）からも吸音材90に至ることになるので、吸音性能をより高めることができる。
なお、格納部80の側面83にも貫通穴82を開けることにすればより吸音性能を更に高めることができる。また、上側の格納部80の蓋81に貫通穴82を開けると内部の吸音材90の小片が貫通穴82を通過して空間部70に出てしまい、空間部70の見た目が悪化するおそれがあるので、上側の格納部80の蓋81には貫通穴82を開けないことにしてもよい。 Next, the sound absorbing function of the partition device 10 of the present invention will be described.
The panel 20 vibrates under the influence of the sound (vibration of air) generated outside the panel 20, and the air inside the space 70 vibrates. As shown by the arrow A in FIG. 3, a part of the vibration of the air in the space 70 is absorbed by the sound absorbing material 90 through the through hole 82 provided in the lid 81 of the upper and lower storage parts 80, and the other part is absorbed. It reaches the side surface 83 of the storage unit 80 through the vibration introduction path 100. As a result, the side surface 83 of the storage unit 80 vibrates, and the air inside the storage unit 80 vibrates under the influence of this vibration and is absorbed by the sound absorbing material 90.
In the present invention, the vibration of the air in the space 70 is absorbed not only by passing through the through hole 82 and being absorbed by the sound absorbing material 90, but also by vibrating the side surface 83 of the storage 80 by using the vibration introduction path 100. To do. Since the vibration of the air reaches not only the sound absorbing material 90 from the vertical direction (vertical direction) but also from the horizontal direction (front-back direction), the sound absorbing performance can be further improved.
If a through hole 82 is also formed in the side surface 83 of the storage portion 80, the sound absorption performance can be further improved. Further, if a through hole 82 is formed in the lid 81 of the upper storage portion 80, a small piece of the sound absorbing material 90 inside may pass through the through hole 82 and come out to the space portion 70, which may deteriorate the appearance of the space portion 70. Therefore, the through hole 82 may not be formed in the lid 81 of the upper storage portion 80.

［第2の実施の形態］
次に、本発明の間仕切り装置の第2の実施の形態について説明するが、上記第1の実施の形態と同様の構成となる箇所については同一の符号を付してその説明を省略する。
図4に示すように、本実施の形態の間仕切り装置11は蓋81の前後の端部が屈曲している。当該屈曲箇所84はビード113に接触しておらず、振動導入路100が空間部70から連続する構造になっている。実験の結果、本実施の形態の間仕切り装置11であっても、格納部80の前後の側面83に振動導入路100を設けることによって従来の間仕切り装置10と比較して高い吸音性能を有することを確認した。 [Second Embodiment]
Next, the second embodiment of the partition device of the present invention will be described, but the same reference numerals will be given to the parts having the same configuration as the first embodiment, and the description thereof will be omitted.
As shown in FIG. 4, in the partition device 11 of the present embodiment, the front and rear ends of the lid 81 are bent. The bent portion 84 does not contact the bead 113, and the vibration introduction path 100 has a structure continuous from the space 70. As a result of the experiment, it was found that even the partition device 11 of the present embodiment has higher sound absorption performance than the conventional partition device 10 by providing the vibration introduction path 100 on the front and rear side surfaces 83 of the storage unit 80. confirmed.

本発明は、吸音性能に優れた間仕切り装置に関するものであり、産業上の利用可能性を有する。 The present invention relates to a partition device having excellent sound absorption performance, and has industrial applicability.
