Description
【考案の詳細な説明】 （産業上の利用分野） この考案はピアノ用防振パネルに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a vibration isolation panel for a piano.
（従来の技術） 従来のこの種のピアノ用防振パネルは、ピアノの打弦音
を減衰させるため、種々の防音パネルや防振パネルが提
案されている。(Prior Art) In this type of conventional vibration damping panel for a piano, various soundproofing panels and vibration damping panels have been proposed in order to attenuate the string striking sound of the piano.
例えば、第４図，第５図に示すようなピアノ本体１の下
面に硬質ゴム等からなる防音・防振パネル２が用いられ
ていた。For example, a soundproof / vibration panel 2 made of hard rubber or the like was used on the lower surface of the piano body 1 as shown in FIGS. 4 and 5.
（この考案が解決しようとする問題点） しかしながら、このような硬質ゴムによる防音・防振パ
ネルの場合は、ある特定の周波数音域の周波数はある程
度の減衰（吸音・吸振）はするが、その他の周波数音域
は減衰量が少ないという不具合があった。(Problems to be solved by this invention) However, in the case of such a soundproof / vibration panel made of hard rubber, the frequency of a certain specific frequency range is attenuated (sound absorption / vibration) to some extent, but other There was a problem that there was little attenuation in the frequency range.
この考案は、上記のような不具合を解消し、広い周波数
音域に亙って良好な減衰特性が得られるピアノ用防振パ
ネルを提供するものである。This invention solves the above-mentioned problems and provides a vibration-proof panel for a piano that can obtain good damping characteristics over a wide frequency range.
（実施例） 以下、この考案の一実施例を図面にそって詳細に説明す
る。(Embodiment) An embodiment of the present invention will be described in detail below with reference to the drawings.
この考案のピアノ用防振パネルは、第１図，第２図に示

するグラスウール等の軟質材４と、該軟質材４を包む外
装材５と、該外装材５の上面及び周囲を覆う硬質の蓋部
材６とから構成される。As shown in FIGS. 1 and 2, the vibration isolating panel for a piano of the present invention comprises a cork core material 3, a soft material 4 such as glass wool covering the cork core material 3 around the cork core material 3, and the soft material 4. It is composed of an exterior material 5 to be wrapped and a hard lid member 6 that covers the upper surface and the periphery of the exterior material 5.
なお、軟質材４を包む外装材５の高さ及び周囲は、前記
蓋部材６よりも多少高く且つ大きく形成しておき、蓋部
材６の上部にピアノ等の重量物が載置された場合でも、
軟質材４を包む外装材５からなる部分は蓋部材６の中で
圧縮された状態で蓋部材６と床Ｆとの間に設定される。It should be noted that the height and circumference of the exterior material 5 that wraps the soft material 4 is formed to be slightly higher and larger than the lid member 6, and even when a heavy object such as a piano is placed on the lid member 6, ,
A portion formed of the exterior material 5 that wraps the soft material 4 is set between the lid member 6 and the floor F while being compressed in the lid member 6.
第３図は第１図におけるＢ−Ｂ′線断面図である。FIG. 3 is a sectional view taken along the line BB ′ in FIG.
図において、８は硬質ゴム部材が嵌め込まれている凹部
であり、この凹部８は丸形状でもよいが種々の器種によ
ってキャスターの位置も変わるので、どのような器種に
おいても対応できるように長方形の凹部ととすればよ
い。In the figure, 8 is a recess in which a hard rubber member is fitted. The recess 8 may be round, but the position of the caster also changes depending on various types of equipment, so that it can be used in any type of equipment. It may be a concave portion.
（考案の効果） この考案は上記のように構成したので、ピアノの振動音
を減衰させて床方向に伝播していたピアノ音を吸収して
減少させるので、従来の防音パネルに比較して一層の防
振性が向上する。(Effect of the Invention) Since the present invention is configured as described above, the vibration sound of the piano is attenuated and the piano sound propagating in the floor direction is absorbed and reduced. Therefore, it is more effective than the conventional soundproof panel. The anti-vibration property of is improved.
なお、上表に示すように、本考案の防振パネルをセット
した場合には、周波数２５０Hzでは４７ｄｂであり、何
もない場合より−４ｄｂ減衰、周波数５００Hzでは４３
ｄｂであり、何もない場合より−６ｄｂ減衰、１ＫHzで
は−４ｄｂ、２ＫHzでは−５ｄｂも床方向に伝播してい
たピアノ音を減衰することができた。 In addition, as shown in the above table, when the anti-vibration panel of the present invention is set, it is 47 dB at a frequency of 250 Hz, is -4 dB more attenuated than when there is nothing, and is 43 at a frequency of 500 Hz.
It was dB, and it was possible to attenuate the piano sound propagating in the floor direction by -6db, -4db at 1KHz and -5db at 2KHz, compared to the case without any noise.
第１図に示した防振パネルは、ピアノ本体の右側用（ま
たは片側用）のみを示したが、このような防振パネルが
一対使用される。The anti-vibration panel shown in FIG. 1 is only for the right side (or one side) of the piano body, but a pair of such anti-vibration panels are used.
