摘要： A damper assembly for a piano includes a rail assembly with an adjustable mount for mounting the rail assembly (311) to the piano case (40) and a plurality of underlevers (307) coupled to the rail assembly. The rail assembly (311) is configured for vertical adjustment: in which the rail assembly can define a vertical slot or discrete adjustment; and in which the rail assembly defines openings arranged vertically. The adjustable mount includes mounting blocks (342, 342a) and the rail is mounted to the blocks for rotation relative to the block. The mounting blocks each define an adjustment slot (333b). A method of simultaneously adjusting a plurality of piano underlevers in a piano includes mounting damper assembly to a piano case with an adjustable mount, and adjusting the position of a rail assembly of the damper assembly relative to the case.

摘要： In a piano normally of a grand piano type, key action mechanism includes a combination of a fly lever distal end (50) acting on a hammer lever (20) through an intermediate thrust balancing lever (27), the thrust balancing lever (27) being pivoted at an intermediate portion (43) between proximal and distal ends thereof, and the thrust balancing lever distal end (42) having a change-of-direction roller (49) over which a non-resilient cord (48) is drawn, one end of the cord (48) being connected to an intermediate portion (47) of a wippen lever (25) pivoted at one end thereof, and an opposite end of the cord (48) being connected to a proximate end of a helical spring (46), and a distal end of the helical spring (46) being connected to an intermediate portion of the fly lever (26) of which the fly lever's lower portion is pivotably mounted on a distal end (34) of the wippen lever (25), such that when an upward portion of a laterally-extending proximal end (35) of the fly lever is raised to contact an abutment (36), further raising of the wippen's distal end (54) moves the thrust balancing distal end (42) upwardly as a result of the fly lever's distal end (50) pivotally moving laterally from beneath the thrust balancing lever's distal end (42), downward pressure on the change-of-direction roller (49) increasing as the fly lever's distal (50) end pivots laterally.

摘要： A piano action (10) includes a wippen (14) having a wippen body (24). The wippen body (24) is pivotally mountable on a first rail (20) of a piano. A repetition lever (38) is pivotally mounted on the wippen body (24). A jack (46) is also pivotally mounted on the wippen body (24). A repetition lever spring (48) is interposed between the repetition lever (38) and the wippen body (24) and is pivotally mounted to the repetition lever (38). The repetition lever spring (48) has a first limb (54) which acts on the jack (46) for restoring the jack (46) to its rest position and a second limb (52) which acts on the repetition lever (38) for restoring the repetition lever (38) to its rest position. The second limb (52) is shorter than the first limb (54) such that a free end of the second limb (52) is out of engagement with the repetition lever (38) and is shaped and dimensioned to move together with the repetition lever (38). The first limb (54), when the wippen (14) is in its rest position, in use, is substantially rectilinear along its length.
