摘要： A damper unit for a piano is provided in which the position of a hammer stop rail for contacting the hammer shanks before the hammers strike the strings can be changed from an inoperative retracted position to a stop position with a relatively small drive force and the hammer stop rail is firmly and reliably positioned at the stop position. Stop rail support arms for supporting the hammer stop rail are connected, via linkage mechanisms composed of links and lever arms, to a rotary shaft. By pulling a wire that is connected to the rotary shaft, the rotary shaft is rotated, such that the hammer stop rail can be positioned, via the linkages, at the stop position and the retracted position, in which the hammer stop rail does not contact the hammer shanks. As compared with the conventional damper unit, the position of the hammer stop rail can be changed with a relatively small drive force. Moreover, the hammer stop rail is thus fixedly positioned at the stop position, thereby reliably dampening the hammer striking sound. The linkage mechanisms may be replaced with a cam mechanism that contacts the stop rail support arms for changing the position of the hammer stop rail.
摘要翻译：提供了一种用于钢琴的阻尼器单元，其中在锤子撞击琴弦之前用于接触琴槌柄的琴槌轨道的位置可以以相对较小的驱动力从不工作的缩回位置改变到停止位置，并且锤子停止导轨牢固可靠地定位在停止位置。通过由连杆和杠杆臂组成的连杆机构将支撑锤止轨的止动轨支撑臂连接到旋转轴。通过拉动连接到旋转轴的线，旋转轴旋转，使得槌杆止动轨可以经由连杆在停止位置和缩回位置定位，其中锤停止轨不与其接触锤柄。与传统的阻尼器单元相比，可以以较小的驱动力来改变槌杆挡块的位置。此外，槌杆挡块固定地定位在停止位置，从而可靠地抑制锤击声。连杆机构可以用接触止动轨支撑臂的凸轮机构来代替，以改变槌杆止动轨的位置。

摘要： A keyboard apparatus for an electronic musical instrument has a jack which is movable and rotatable by a force to be transmitted from a key, and a hammer which is rotatable by a force to be transmitted from the jack. The jack is rotatably engaged by a fulcrum which is provided in the key. The jack is urged to its original position by a spring. The key has a return load applying portion which abuts the hammer when the hammer rotated by the jack returns to its original position.

摘要： A muting device of an upright piano which includes butt, a wippen, a capstan button and a muting mechanism (15). This butt rotates with a hammer which strikes a string of the upright piano. In addition, a jack is provided to come in contact with a lower surface of the butt, and rotates the butt in response to displacement of the key. The jack is supported by the wippen such that it can freely rotate. The capstan button is provided at a back edge portion of the key to transmit displacement of the key to the wippen. The muting mechanism is designed to reduce a string-striking stroke by rotating the hammer. Further, there is provided a key-displacement-transmission-rate changing mechanism. When reducing the string-striking stroke by the muting mechanism, this mechanism raises a displacement transmission point, at which displacement of the key is transmitted to the wippen, toward a rotation center of the key from the capstan button. Preferably, this mechanism includes another capstan button which is placed on an upper surface of the key at a position between the capstan button and rotation center of the key.

摘要： The invention relates to a damper mechanism for upright piano, comprising a damper felt mounted on a damper wood, and in which the damper wood is equipped with a guide stem directionally adjusted perpendicularly to the plane of the strings and guided to move reciprocally in a bore of a block fixed on a support independent of the mechanism controlling the hammers. Members are interposed between the key and the damper guide stem for reciprocally moving the latter in response to the movement of the key.

摘要： There is described a musical instrument such as a piano comprising a plurality of vibratile members such as wires capable of vibration to produce notes of selected frequencies, a hammer mechanism for each said vibratile member for causing vibration thereof, and an actuating mechanism for selectively rotating each hammer from a rest position to strike the vibratile member associated therewith and a return mechanism for rotating the hammer back to its rest position. A hammer rail is provided to support the hammer in a rest position. A control mechanism for the hammer includes a pivotally mounted adaptor having an inertial mass movable in a substantially vertically upwards direction and active upon the hammer when struck thereby to absorb the kinetic energy of the hammer moving towards the hammer rail to thereby exert a decelerative force upon the hammer. The hammer rail has a surface of resiliently deformable material such as felt which the hammer abuts in the rest position thereof. The pivotally mounted adaptor is located for striking by the hammer moving towards the hammer rail substantially at the moment of initial contact of the hammer with the felt.

摘要： An improvement in the action for a harpsichord type of keyboard musical instrument which uses a pneumatic piston to provide a variable pluck loudness. The improvement comprises a new pick-body design which allows several strings to be plucked at once for any single note or key, thus increasing the loudness of the instrument. The invention involves the use of a crank arm which, being restrained by a pneumatic piston, tilts the pick-body and the picks into the strings, the loudness resulting therefrom being proportional to the key-lever velocity.

摘要： Means for adjusting the touch force required to depress the keys of a piano within the range normally preferred by pianists, comprising a plurality of spring member means having a relatively small spring constant (low stiffness). Each spring member means is connected at one of its ends to one of piano keys near the fulcrum thereof. Each spring member means is connected at its other end to a beam located above the keys and extending transversely thereof the full length of the keyboard. At least one of the connections of each spring member means is adjustable. The beam may be a single continuous member, or it may be made up of segments corresponding to groups of adjacent keys. In the initial adjustment each spring member means is typically prestressed by means of its adjustable connection to set the static touch force of its respective key to the desired value.

摘要： In the upright piano action, the wire protruding up from the damper lever leaning or biased towards the string contacts and slides back to and forth along a pin fixed and protruding straight out from the hammer spring rail towards the string.On the sostenuto rod, attached and moveable horizontally on top of the hammer spring rail, is fixed a thin wire arm with a hooked end extending straight towards the space between the strings, reaching just long enough to clear the damper lever wire as it travels horizontally back and forth when the damper is on the string.When the damper moves off the string after depression of the key, the damper wire slides back along the side of pin in hammer spring rail and is hooked by wire arm on sostenuto rod when it moves horizontally towards the damper wire clamping it securely back, even after release of the depressed key. So long as the sostenuto rod is held in that position, thus allowing the string, after being struck by hammer to continue to vibrate sustaining the tone.A plurality of such sostenuto wire spring arms and hammer spring rail pins for a plurality of damper levers are fixed to the transversely extending hammer spring rail and sostenuto rod which moves the spring arms in unison toward the damper lever wires catching those that are off the string against the hammer spring rail pins and ignoring those that are on the strings allowing all of the piano action to function normally by moving the spring arms beyond the reach of the damper lever wires.

摘要： In addition to the single combination of a tone generator such as a string with a hammer, a further combination is provided by an auxiliary tone generator such as an elongated thin metal strap and/or an auxiliary hammer preferably accompanied by a mechanism for effecting selective striking contact for tonal vibration between the tone generator or generators and the hammer or hammers when an associated common key is operated. Selectively combined simultaneous striking by the hammer or hammers generates tones of enriched tone color and volume by single key operation.
