摘要： A sostenuto mechanism linked to a sostenuto pedal and a sostenuto rod of a keyboard instrument, and the keyboard instrument are provided. The sostenuto mechanism includes a fixed member configured to be fixed to at least one of a middle beam or a key bed of the keyboard instrument, a movable member movably supported by the fixed member, and a movement transmission. The movement transmission is configured to be interposed between the sostenuto pedal and the movable member to transmit movement of the sostenuto pedal to the movable member. The moveable member is movable relative to the fixed member to turn the sostenuto rod in response to depression of the sostenuto pedal.

摘要： A lever 40 is supported by a lever supporting portion 41. Through a first pivoting member 52, the lever 40 is urged by a reaction force stabilization spring 54, a first spring 55 and a second spring 56. The downward displacement of a second pivoting member 53 is restricted by a fixed supporting member FR. If the urging force of the first spring 55 exceeds the urging force of the second spring 56, the second pivoting member 53 is displaced upward. A contact member which is in contact with the first pivoting member 52 and the second pivoting member 53 to produce friction force is also provided.

摘要： A muffler mechanism that reduces the volume of an acoustic piano without altering the feel of the piano to a human pianist. One embodiment includes a highly configurable piano muffler kit that may be mounted into pianos of various models. The muffler mechanism includes a cushioning member, which muffles the sound of the hammer striking the string and reduces the volume of the sound made by the string's vibration. The muffler mechanism also includes shims that may be used to position the cushioning member between a hammer let-off position and the string. This may allow for muffled piano playing without a noticeable change in the resistance of the keys. The muffler mechanism is mounted using brackets with a relatively small footprint. This allows the piano muffler to be installed without removing all of the dampers.
摘要翻译： 消声器机构可以减轻钢琴的音量，而不会改变钢琴对钢琴人的感觉。 一个实施例包括高度可配置的钢琴消声器套件，其可以安装到各种型号的钢琴中。 消声器机构包括缓冲构件，该缓冲构件将敲击琴弦的锤的声音消除，并减小由弦的振动产生的声音的音量。 消声器机构还包括可用于将缓冲构件定位在锤子释放位置和弦之间的垫片。 这可能允许无声的钢琴演奏，而键的阻力没有明显变化。 消声器机构使用相对较小占地面积的支架安装。 这样可以安装钢琴消声器，而不需要拆除所有的阻尼器。

摘要： A pedal device of a keyboard instrument which makes it possible to stably secure a required action of a pedal, facilitate assembly thereof, and reduce manufacturing costs. A pedal device for a keyboard instrument of the present invention comprises a chassis 8 having a support portion 30, and a pedal 7 vertically pivotally mounted on the chassis 8, for a downward stepped-on operation. The pedal 7 has a cover 15 formed of a synthetic resin, and pivotally supported on the support portion 30 of the chassis 8, and a pedal body 14 fixed to the cover 15 in a state in which a rear part of the pedal body is covered by the cover 15, and protruding forward from the chassis 8. Further, the pedal device has a chassis 8 having an opening 29 which opens downward, the pedal 7 pivotally supported on the chassis 8 and protruding forward from the opening 29, a return spring 11 disposed under the pedal 7, for retuning the pedal 7 after the stepping-on operation, and a plate 12 fixed to the chassis 8 in a state in which the return spring 11 is interposed, in a manner blocking the opening 29.

摘要： A lever 40 is supported by a lever supporting portion 41. The lever 40 is urged by a spring 45. A friction producing member 47 is in contact with a pivot restricting member 46 which is interlocked with the lever 40 to produce a frictional force in a direction opposite to the direction in which the lever 40 pivots. Such a configuration allows a pedal apparatus to exhibit hysteresis in characteristics of the amount of depression of the lever 40 and reaction force.
