Abstract:
A piano (1) having a dense sound-enhancing component (2), said piano (1) having a case (6), a frame (3) located within the case (6), strings (5) located within the frame (3), keys (9) in connection with hammers (11), two bridges (13) each of stone having a top face (27), a bottom face (28), a first side (29) and a second side (30), bridge pins (16) extending from the top face (27) at an angle, the strings (5) extending across the bridges (13) adjacent to the bridge pins (16), a soundboard (4) and an amount of epoxy (18) located between the bridges (13) and soundboard (4). The dense sound-enhancing component (2) is a stone material, preferably granite, and enhances the sound of the piano (1) by holding and sustaining pitch longer, providing a longer and stronger signal, providing a higher volume or decibel level and having a decreased decibel fall-off as compared to conventional pianos utilizing wood bridge(s).
Abstract:
A piano tuning retention system includes first and second bushings, each having a threaded upper longitudinal end and a lower longitudinal end that defines a polygonal interior for mating with a polygonal end of a respective piano tuning pin, first and second threaded fasteners corresponding to the threaded upper longitudinal ends of the bushings, first and second sleeves that fit over the bushings, each of the sleeves having an upper longitudinal end with an inward radial extension that defines a reduced inner diameter and a lower longitudinal end that defines a catch (e.g. a notch) extending in a circumferential direction of the sleeve for engagement with a piano string, and a bridge configured to be sandwiched between the threaded fasteners and the inward radial extensions of the sleeves with the bushings disposed within the sleeves and the threaded fasteners fastened to the threaded upper longitudinal ends of the bushings.
Abstract:
Die Erfindung betrifft einen Rahmen für einen Flügel oder ein Piano sowie ein Verfahren zur Verbesserung eines Flügels oder eines Pianos mit einem solchen Rahmen. Ein erfindungsgemäßer Rahmen (24) für einen Flügel (10) oder ein Piano umfasst eine Vorderplatte (28), eine Hinterplatte (30) sowie mehrere, die Vorderplatte (28) und die Hinterplatte (30) verbindende Längsstreben (32). Dabei ist an mindestens einer Längsstrebe (32) mit einer Mindestlänge von 500 mm in deren Längserstreckungsrichtung betrachtet zwischen der Vorderplatte (28) und der Hinterplatte (30) in einem diskreten Bereich der Längsstrebe (32) durch partielle Vergrößerung der Querschnittsfläche, durch partielle Verwendung eines Werkstoffs mit höherer Dichte und/oder durch Fixieren eines separaten Elements in einem diskreten Bereich der Längsstrebe (32) mindestens ein lokales Massemaximum (36) ausgebildet das sich über eine Länge der Längsstrebe von maximal 150 mm erstreckt. Ferner weist die mindestens eine Längsstrebe (32), an welcher das mindestens eine lokale Massemaximum (36) ausgebildet ist, einen Verbindungsbereich zu einem weiteren Element auf. Ferner ist an dieser Längsstrebe an dieser Längsstrebe (32) beabstandet von diesem Verbindungsbereich mindestens ein lokales Massemaximum (36) ausgebildet.

Abstract:
A tuning mechanism for altering the tuning of the strings (4) of a stringed instrument such as piano or hammered dulcimer comprises a plurality of sliding bridges (8; 36) mounted for sliding relative to the strings (4) over a predetermined travel. The bridges (8; 36) are in contact with the strings during at least a part of their travel, thereby allowing micro-tonal and semi-tonal interval changes in tuning to be effected. The predetermined travels of the sliding bridges are different to one another. Also disclosed is an instrument incorporating such a tuning mechanism and a mechanism which may be retro-fitted to an existing instrument.
Abstract:
There is disclosed herein a piano frame (10) comprising a main plate (12) having a first major surface (14) for supporting piano strings and an opposite second major surface (16) for supporting a soundboard (18). First (20), second (22), third (24) and fourth (26) elongate anchor zones are located on the first major surface (14) for anchoring, respectively, first end (upper, tuneable end) and second end (lower, hitched end) of bass strings and first end (upper, tuneable end) and second end (lower, hitched end) of treble strings. As best seen in Figs. 1 and 2, a plurality of openings (28) are provided in the main plate (12) between the third anchor zone (24) and the fourth anchor zone (26). A truss defined by a plurality bracing members (30) integrally formed in the main plate extends between the third anchor zone (24) and the fourth anchor zone (26). The bracing members (30) are located wholly between a plane extending between the third (24) and fourth (26) anchor zones and a plane defined by the second major surface (16) of the main plate (12).
Abstract:
A mechanism for supporting the weight of a piano lid is disclosed. One or more pneumatic cylinders and arms are used to assist a user in opening and closing the piano lid. In one embodiment, a guiding cup can be removably attached to the frame of the piano below each pneumatic cylinder. When the piano lid is open, the piston arm of the pneumatic cylinder engages the guiding cup. Because the pneumatic cylinder is not attached to the piano frame, the piano lid can be completely removed without the use of tools. Another embodiment provides a mounting bracket that fits over the rear frame of a piano, allowing the mechanism to be retrofit to any existing piano without any damage thereto.
