摘要： A silent piano includes a hammer stopper (71) changed between a free position out of the trajectories of hammer shanks (25b) and a blocking position on the trajectories for blocking strings (30) from being struck with the hammers (25) and a tandem regulating button mechanism (27) having standard regulating buttons (27b) and regulating bars (27c) used together with the hammer stopper (71) changed in the blocking position for changing escaping speed of jacks (20g), and an adjusting mechanism (27e) is provided between the regulating bars (27c) and a shaft (28a) for adjusting the regulating bars (27c) to appropriate angular positions, wherein the adjusting mechanism (27e) has regulating screws (27f) projecting from stationary brackets (29a) fixed to the shaft (28a) into a free space created in front of the array of action mechanisms (20) so that a tuner easily adjusts the regulating bars (27c) to the appropriate angular positions without removing the action mechanisms (20) from on the key bed.

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.

摘要： A knuckle assembly for an escapement action (200) of a piano includes a knuckle (150), a jack retainer (204), and an adjustment means acting between the jack retainer (204) and the knuckle (150) for positioning the jack retainer (204) relative to the knuckle (150). The knuckle (150) is arranged for escape of the jack (120) from engagement with a knuckle surface during depression of a piano key (102). The jack retainer (204) retains the jack (120) in an "at rest" position with the jack (120) in engagement with the knuckle surface in opposition to force of a spring (160) urging the jack (120) toward the "at rest" position. A spring brake is adapted to be mounted to a repetition support (110) of an escapement action (200) of a piano for selective contact with a spring of the escapement action (200) in a manner to adjust the spring force urging a jack (120) of the escapement action(200) toward an "at rest" position.
摘要翻译：用于钢琴的擒纵动作（200）的关节组件包括转向节（150），千斤顶保持器（204）以及作用在千斤顶保持器（204）与转向节（150）之间用于定位千斤顶保持器（204）相对于转向节（150）。关节（150）被布置为在压下钢琴键（102）期间使千斤顶（120）脱离与转向节表面的接合。该插孔保持器204将插孔120保持在“静止”位置，插孔120与转向节表面接合，与弹簧160的作用力相反，该弹簧160迫使插孔120朝向“ 静止“的位置。弹簧制动器适于安装到钢琴的擒纵动作（200）的重复支架（110）上，以便与擒纵动作（200）的弹簧选择性地接触，以调节推动千斤顶的弹簧力（200）朝向“静止”位置移动。

摘要： Composite or plastic molded articles used in a grand piano piano action. A piano action actuates in response to depression on a piano key to swing a hammer into a piano string. The articles comprise a grand piano piano action with significantly less dynamic mass which is much more responsive to the touch. In addition, the new action provides the valuable collateral benefits of increased efficiency of manufacture and maintenance. The invention also provides the capability to achieve true simultaneous half stroke design in both the sharp and white keys. Additionally, the application discloses a universal composite grand piano piano action that is capable of convenient installation into any brand of grand piano.

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： The invention relates to a grand piano action comprising a hammer jack (4), a repetition lever (5) that is independent therefrom, and a hammer roller (8a), which is arranged on a hammer shank (6). Said hammer roller is located at a customary distance from the hammer jack (4) and is in contact with the repetition lever (5). The grand piano action is characterized in that the hammer roller (8a) is mounted such that it can rotate around the axis thereof. As a result, the exertion of force required for pressing down the key is reduced and playing is made easier.

摘要： An escapement action (200) for a piano includes a hammershank (132) having a first end mounted to pivot relative to the piano and a second end carrying a hammer (130) to strike a tensioned string (140) of the piano, with a knuckle (150) disposed therealong between the first and second ends. A repetition support (110) bearing against a key (102) of the piano is mounted to pivot relative to the piano in response to depression of the key (102). A jack (120) has a first portion extending from a pivot connection (121) with the repetition support and defines a jack surface disposed for engagement with a knuckle (150) surface, the jack (120) arranged for escape of the jack surface from engagement with the knuckle surface during depression of the key (102). A spring (160) urges the jack toward an "at rest" position with the jack surface in engagement with the knuckle surface. A jack retainer assembly (204) dependent from the hammershank (132) between the second end and the knuckle includes a cushion surface (210) positioned to retain the jack (120) in "at rest" position in opposition to force of the spring.
