特開平10-161640Japanese Patent Laid-Open No. 10-161640

従来のグランドピアノの大屋根の開閉構造の場合、演奏中には大屋根を開いた状態で使用するため、ピアノ内部から発する音は、開いた状態の大屋根に反射することにより、大屋根の開口側により多くの音が拡散されることになる。かつてはその拡散される側に聴衆が配される演奏会場が多かったが、昨今では多様なコンサートホールが利用されるため、ピアノの設置場所を中心にしてピアノを取り囲むように聴衆が配される場合も多々ある。そのような場合には、大屋根の開口側と反対側にいる聴衆にとっては、ピアノの大屋根からの反射音が小さくなりピアノの音を十分満足して聴くことができなかった。 In the case of a conventional grand piano with a retractable roof structure, the roof is opened during a performance, so the sound emitted from the inside of the piano is reflected by the open roof. More sound will be diffused on the open side. In the past, there were many concert venues where the audience was arranged on the side where the music was diffused, but in recent years, since various concert halls are used, the audience is arranged so as to surround the piano centered on the place where the piano is installed. There are many cases. In such a case, the audience on the side opposite to the opening of the large roof could not hear the sound of the piano satisfactorily because the reflected sound from the large roof of the piano would be reduced.

上記課題を解決するために、本発明は大屋根と側板が蝶番により開閉可能に連結されたグランドピアノに使用するグランドピアノ用大屋根支持具であって、グランドピアノの側板を挟持する一対の挟持板と、該挟持板を中央部で連結する固定板とを備える側板挟持部と、前記固定板と前記挟持板の一端部の間の一挟持板側に、前記蝶番の一片が挿入される蝶番挿入孔を有するように取り付けられた断面コの字型の蝶番支持部とからなることを特徴とする。また、前記側板挟持部の前記挟持板と前記固定板のグランドピアノの側板と接触する部分には、緩衝材を設けたことを特徴とする。 In order to solve the above-mentioned problems, the present invention provides a large roof support for use in a grand piano in which the large roof and the side plates are connected by hinges so that they can be opened and closed, comprising a pair of holders for holding the side plates of the grand piano. A side plate clamping portion including a plate and a fixing plate connecting the clamping plates at a central portion thereof, and a hinge into which one piece of the hinge is inserted on the one clamping plate side between the fixing plate and one end of the clamping plate. and a hinge support portion having a U-shaped cross section attached so as to have an insertion hole. Further, a cushioning material is provided at a portion of the holding plate of the side plate holding portion and a portion of the fixing plate that contacts the side plate of the grand piano.

上記手段による本発明のグランドピアノ用大屋根支持具によれば、当該支持具を複数用いて、大屋根全体を均等にピアノの側板端部から浮かせることができるので、浮かせた状態で形成される大屋根と側板端部との空隙から、ピアノの全周方向に均等にピアノの演奏音を拡散させることができるため、ピアノが設置される場所に対して、どの方向に聴衆がいても、同等のピアノの演奏音を聴くことができるようになる。 According to the large roof support for a grand piano according to the above-described means of the present invention, the entire large roof can be evenly lifted from the end portions of the side plates of the piano by using a plurality of such supports. The gap between the large roof and the edge of the side plate allows the sound of the piano to be diffused evenly in all directions around the piano. You will be able to listen to the sound of the piano playing.

本発明のグランドピアノ用大屋根支持具の具体的構造を以下の実施例に示す。 The specific structure of the large roof support for a grand piano of the present invention will be shown in the following examples.

図1は本発明のグランドピアノ用大屋根支持具の外観を示す斜視図である。図1において、側板挟持部1は一対の挟持板1a、1bが一定の間隔を有して平行に配され、前記挟持板1a、1bの一端部側で連結板1cにより結合されている。また、前記挟持板1a、1bの中央部には固定板1dが前記連結板1cと平行になるように固定されている。さらに、前記挟持板1b側の前記連結板1cと固定板1dの間には、断面コの字型の蝶番支持部2が蝶番挿入孔2aを形成するように固定されている。 FIG. 1 is a perspective view showing the appearance of a large roof support for a grand piano according to the present invention. In FIG. 1, a side plate holding portion 1 has a pair of holding plates 1a and 1b arranged parallel to each other at a constant interval, and the holding plates 1a and 1b are connected at one end side by a connecting plate 1c. A fixing plate 1d is fixed to the central portion of the clamping plates 1a and 1b so as to be parallel to the connecting plate 1c. Further, between the connecting plate 1c and the fixing plate 1d on the clamping plate 1b side, a hinge support portion 2 having a U-shaped cross section is fixed so as to form a hinge insertion hole 2a.

図2及び図3は本発明のグランドピアノ用大屋根支持具の使用状態を示す断面図であり、それぞれ大屋根を閉じた状態を示す図、大屋根を開いた状態を示す図である。これらの図は、蝶番の一片が蝶番挿入孔に挿入途中を示しており、実際には蝶番の一片を蝶番挿入孔に完全に挿入した状態で使用する。これらの図において、側板挟持部1は一対の挟持板1a、1bにより、グランドピアノの側板6を挟み込むように固定されており、前記側板6と接する部分には、フェルトからなる緩衝材3が設けられている。また、蝶番支持部2の蝶番挿入孔2aにはグランドピアノの大屋根5の一端辺に取り付けられた蝶番4の一片が挿入されている。前記緩衝材3により、グランドピアノ用大屋根支持具をグランドピアノの側板6に固定する際、側板6に傷が付くことを防止できるとともに、グランドピアノ大屋根支持具のガタつきも抑えられるので、ピアノ演奏音による大屋根への不快な振動を抑制することができる。 FIG. 2 and FIG. 3 are cross-sectional views showing how the large roof support for a grand piano of the present invention is used, in which the large roof is closed and the large roof is opened, respectively. These drawings show one piece of the hinge being inserted into the hinge insertion hole, and actually the hinge is used in a state in which it is completely inserted into the hinge insertion hole. In these figures, a side plate clamping portion 1 is fixed by a pair of clamping plates 1a and 1b so as to sandwich a side plate 6 of a grand piano. It is A piece of a hinge 4 attached to one end side of the large roof 5 of the grand piano is inserted into the hinge insertion hole 2a of the hinge support portion 2. As shown in FIG. The cushioning material 3 prevents the side plate 6 from being damaged when the grand piano roof support is fixed to the side plate 6 of the grand piano, and also suppresses rattling of the grand piano roof support. Unpleasant vibrations to the large roof due to piano playing sound can be suppressed.

図4は本発明のグランドピアノ用大屋根支持具を使用して大屋根を閉じた状態を示すグランドピアノの外観図である。図4において、本発明のグランドピアノ用大屋根支持具はグランドピアノの側板6の周縁部に側板挟持部により複数個固定され、大屋根5の蝶番が取付けられている側は上述したように、蝶番の一片が蝶番挿入孔に挿入されている。また、大屋根5の蝶番が取付けられていない側は前記連結板1c上に大屋根5が載置されている。 FIG. 4 is an external view of a grand piano showing a state in which the large roof is closed using the grand piano roof support of the present invention. In FIG. 4, a plurality of large roof supports for a grand piano according to the present invention are fixed to the periphery of the side plate 6 of the grand piano by means of side plate clamping portions. A hinge piece is inserted into the hinge insertion hole. On the side of the large roof 5 to which the hinges are not attached, the large roof 5 is placed on the connecting plate 1c.

以上のように、本発明のグランドピアノ用大屋根支持具を使用すれば、大屋根5を閉じた状態でも、大屋根全体を均等にピアノの側板端部から浮かせることができるので、大屋根と側板端部に空隙を形成することができる。なお、この空隙を形成した状態でさらに、大屋根5を従来のように開くことも可能である。また、前記挟持板1a、1b間の前記固定板1dの位置を適宜上下に変更すれば、大屋根と側板端部間の空隙の距離を変えることができるので、演奏会場の聴衆席のレイアウト等に応じて最適なグランドピアノの音の拡散状態を得ることができる。 As described above, if the large roof support for a grand piano of the present invention is used, even when the large roof 5 is closed, the entire large roof can be evenly lifted from the edge of the side plate of the piano. A gap can be formed at the end of the side plate. It should be noted that it is also possible to open the large roof 5 in a conventional manner in a state in which this gap is formed. Further, by appropriately changing the position of the fixing plate 1d between the clamping plates 1a and 1b, the distance of the gap between the large roof and the end of the side plate can be changed. It is possible to obtain the optimum sound diffusion state of the grand piano according to the conditions.
