Abstract: An upright piano main action rail with a special cross sectional shape of its lower half that angles or curves towards the back of the piano to effectively relocate the lower front surface of upright piano main action rail from a position in front of the row of whippen flanges as with the prior art to a relocated new position behind the row of whippen flanges to enable the front mounting of whippen flanges to the main action rail. Upright piano main action rail has all whippen mounting holes located its the lower front surface instead of the lower rear surface as with prior art upright piano main action rails.

Abstract: To provide an action of an upright piano which permits playing of repeated notes on the single key and touch of the keys that are comparable to a grand piano. A first spring (59) is provided to a pushing-up portion (20) of a jack (18), a first spring rest (71) is provided to a jack stop rail (53), and when a jack tail (19) moves away from a regulating button (47), the first spring (59) bent between the pushing-up portion (20) and the first spring rest (71) forces the pushing-up portion (20) to be pushed under a pushed-up portion (27) to be thrust up of a hammer butt (25). A second spring (66) is provided to a damper stop rail (56), a second spring rest (72) is provided to a hammer shank (33), and the second spring (66) bent between the damper stop rail (56) and the second spring rest (72) stops the rotational movement of a hammer (32) before the hammer (32) that moves rotationally by the force of the first spring (59) strikes a string (90).

Abstract: A key actuation system that is designed for use with a keyboard instrument of the type having multiple keys. Each key is pivotally supported and has a front end that is depressed by a player to play a note. The actuation system includes multiple actuators that are operable to move at least some of the keys. The actuators together include a block of ferromagnetic material with a surface with multiple bores defined in the surface. Each of the bores has a diameter. A winding is positioned in each of the bores. Each of the windings has a hole. A piston is provided at least partially in each of the holes, with each piston being in mechanical communication with one of the keys such that movement of the piston causes movement of the key. Each piston has a width. A ferromagnetic flux plate with multiple openings is positioned on the surface of the block of ferromagnetic material with the openings aligned with the bores. The openings each have a width that is less than the diameter of the bores, such that the flux plate partially closes off the upper end of each bore. When the windings are energized, the corresponding piston moves, thereby moving one of the keys.

Abstract: A silencing apparatus is provided for pianos having an electronic sound source as well as the conventional acoustic sound mechanism. The silencing apparatus includes a plurality of arms, a stop rail bridging ends of the arms and a positioning mechanism. When acoustic sound is to be silenced, a wire is pulled by means of an operating lever, thereby pivoting an actuating lever which is connected to one of the arms. This causes the stop rail to pivot to the stop position at which the stop rail abuts against and thereby stops motion of the hammer shanks which move in response to key depressions. The stop rail and the arms thereon define open spaces for accommodating for the presence of the other components, such as damper units, inside the piano. Thus, the silencing apparatus of the present invention travels over a greater range of motion without interfering with the operation of other components inside the piano.

Abstract translation: 为具有电子声源的钢琴以及常规的声音声音机构提供了一种消音装置。 所述消音装置包括多个臂，连接所述臂的端部的止动轨和定位机构。 当声音被静音时，通过操作杆拉动电线，从而枢转连接到一个臂的致动杆。 这使得停止轨道枢转到止动轨道抵靠的停止位置，从而停止响应于键凹陷而移动的锤柄的运动。 止动导轨和其上的臂部限定了用于容纳钢琴内部的其它部件（例如阻尼器单元）的开放空间。 因此，本发明的消音装置在较大的运动范围内行进，而不会妨碍钢琴内其它部件的操作。

Abstract: An acoustic upright piano, an electronic sound system and a hammer stopper form in combination a keyboard musical instrument for generating acoustic sounds in an acoustic sound mode and electronic sounds in an electronic sound mode, and the hammer stopper has a rotatable shaft extending in a lower space under damper blocks of damper assemblies, cushion members projecting into an upper space over the damper blocks and connecting brackets provided between the rotatable shaft and the cushion members, thereby perfectly interrupting hammer motions before an impact on strings in the electronic sound mode.

Abstract: A keyboard musical instrument allowing a player to perform using acoustic tones or electronic sounds is provided. The keyboard is movable between various positions, such as between a raised and a lowered position. In an electronic sound mode, the keyboard is lowered so as to increase a gap between hammer assemblies and associated strings. The keyboard is lowered using cams or lifters to pull down the keyboard so as to increase a gap between hammer assemblies and associated strings. In this mode, each hammer assembly rebounds on a stopper when a corresponding key is selected, thereby giving a desirable piano touch.

Abstract: A keyboard musical instrument selectively generates acoustic sounds and electronic sounds depending upon a mode selected by a player, and has a hammer stopper for interrupting hammers before strikes at strings and an escape accelerator for accelerating an escape of a jack from the hammer assembly in the silent mode earlier than an escape in the acoustic sound mode, thereby preventing the hammer assembly from capture between the jack and the hammer stopper without deterioration of the piano key touch.

Abstract: A keyboard musical instrument lowers a key bed together with a keyboard, key action mechanisms and hammer mechanisms in a silent mode, and a stopper mechanism and a make-up mechanism cause the depressed keys to actuate the key action mechanisms and damper mechanisms as similar to an acoustic sound mode, thereby allowing a player to feel the key touch usual in a performance without an acoustic sound.

Abstract: An acoustic piano, an electronic sound producing system and a controlling system form a keyboard instrument for selectively producing acoustic sounds and electronically synthesized sounds, and the controlling system has a catcher stopper for restricting rotations of catchers before hammer heads strike sets of strings in the electronic sound producing mode, thereby giving the unique piano key-touch to a player without mixing noise with the synthesized sounds.
