Description

Resonanzboden für Saiteninstrumente (Klaviere u. dgl.). Die Erfindung betrifft einen gewölbten Resonanzboden für Saiteninstrumente (Klaviere o. dgl.) mit unregelmäßig - etwa S-förmig -auf der obersten Höhenlinie der Wölbung in gleicher Ebene verlaufendem Steg.Soundboard for string instruments (pianos and the like). The invention relates to a curved soundboard for stringed instruments (pianos or the like) with irregular - approximately S-shaped - on the uppermost contour line of the vault in the same way Level bridge.

Bei den bisher bekannten Resonanzböden dieser Art waren die einzelnen Bretter des Resonanzbodens symmetrisch und gleichmäßig, schildförmig gebogen. Um dem gebogenen Stege eine ebene Auflage zu geben, mußte entweder die Stärke des Stegs je nach der Auflagestelle wechseln oder die Resonanzbodenbretter mit Abflachungen oder Zwischenlagen versehen werden. Hierdurch wurde die Resonanz ungünstig beeinflußt.In the previously known soundboards of this type, the individual The soundboard boards are symmetrical and even, curved in the shape of a shield. Around To give the curved web a level support either had to be the thickness of the web Change depending on the location or the soundboard boards with flats or intermediate layers are provided. This had an adverse effect on the resonance.

Die Erfindung beseitigt diesen Nachteil dadurch, daß die in sich gleich starken Bretter des Resonanzbodens untereinander verschieden und unregelmäßig so gewölbt sind, daß die höchsten Punkte ihrer Wölbung zueinander seitlich verschoben, aber genau an den Stellen liegen, über die der unregelmäßig gebogene Steg entlangläuft.The invention eliminates this disadvantage in that the inherently the same strong boards of the soundboard different from each other and irregularly like that are arched so that the highest points of their arching are shifted laterally to one another, but lie exactly at the points over which the irregularly curved web runs along.

Die Zeichnung zeigt in Abb. z einen Resonanzboden mit unregelmäßig gebogenem Stege in der Draufsicht, in Abb. z die Wölbung der einzelnen Bretter bei bisher bekannten Resonanzböden im Ouerschnitt, in Abb. 3 die Wölbung der Resonanzbodenbretter gemäß der Erfindung in einer beispielsweisen Ausführungsform. Über dem aus mehreren, beispielsweise in den Richtungen c-d, x-y und a-b verlaufenden Brettern zusammengesetzten Resonanzboden R ist der Hauptsteg S in der bekannten Weise unregelmäßig geführt. Um die von der Mittellinie o-t seitlich abweichenden Stellen f und e des Steges in gleicher, ebener Höhe auf den gleichmäßig gewölbten Brettern g-h, z-u und k-1 (Abb. a) lagern zu können, mußten die Bretter g-h und k-1 an den Stellen i und m Erhöhungen haben, die der Höhe des Mittelbrettes bei t entsprach.The drawing shows in Fig.Z a soundboard with irregularly curved webs in plan view, in Fig.Z the curvature of the individual boards in previously known soundboards in cross-section, in Fig. 3 the curvature of the soundboard boards according to the invention in an exemplary embodiment. Above the soundboard R, which is composed of several boards running, for example, in the directions cd, xy and ab, the main web S is irregularly guided in the known manner. In order to be able to store the points f and e of the web that deviate laterally from the center line ot at the same level on the evenly curved boards gh, zu and k-1 (Fig. A), the boards gh and k-1 had to be attached to the Places i and m have elevations that corresponded to the height of the middle board at t.

Erfindungsgemäß haben die Bretter q-y, v-w und n-o (Abb. 3) in sich gleichmäßige Stärke. Sie sind unregelmäßig so gewölbt, daß ihre höchsten Punkte s und p genau unter den Stellen f und e liegen, über die der Steg S hinwegläuft.According to the invention, the boards have q-y, v-w and n-o (Fig. 3) uniform strength. They are so irregularly arched that their highest points s and p lie exactly below the points f and e over which the web S runs.
