| 20130247740 | DAMPER ACTION FOR UPRIGHT PIANO WITH SOSTENUTO SPRING TAB USING TENSION FROM THE DAMPER SPRING - A damper action for an upright piano that comprises a springed tab on the damper lever that “ratchets” or gives way or folds away in one direction and does not in the other, to provide retention when the spring tab passes by the longitudinal ridge on the sostenuto rod in one direction and non-retention when the spring tab passes by the longitudinal ridge on the sostenuto rod the other direction. The ratchet aspect of the spring tab uses tension from the damper spring and does not require a separate spring to apply tension to yield the ratchet effect. | 09-26-2013 |

| 20100251872 | Piano muffler system and method of installation - 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. | 10-07-2010 |

| 20140305276 | METHOD AND APPARATUS FOR IDENTIFYING HALF PEDAL REGION IN KEYBOARD MUSICAL INSTRUMENT - Each of Dampers provided for each of keys is controlled in response to both an operation of a damper pedal and an operation of the corresponding key. For each of the dampers and over one stroke of the pedal in at least one of depressing releasing directions of the pedal, load information indicative of loads imposed on a portion linked to the damper is acquired in association with individual stroke positions of the pedal. Then, for each of the dampers, a half pedal region is identified on the basis of relationship between the stroke positions and the loads corresponding to the stroke positions. The portion linked to the damper may be any suitable portion related to a damper lever moving in an up-down direction in interlocked relation to both of vertical movement of a lifting rail responsive to an operation of the pedal and an operation of the key. | 10-16-2014 |
| 20140305277 | METHOD AND APPARATUS FOR IDENTIFYING KEY-DAMPER HALF REGION OF KEYBOARD MUSICAL INSTRUMENT - For each key and without damping action of dampers deactivated by a damper pedal, loads imposed on a portion of the key acting on the damper are measured while the key is moved over one stroke in at least one of key-depressing and key-releasing directions, in association with a plurality of stroke positions in the one stroke of the key. For each key, a key-damper half region is identified on the basis of relationship between the individual stroke positions and the measured loads corresponding to the stroke positions. Then, on the basis of the key-damper half regions identified for the individual keys, a half point is determined separately for each of the keys, or a half point common to a group of a plurality of the keys is determined. | 10-16-2014 |

| 20100162873 | PEDAL DEVICE FOR KEYBOARD INSTRUMENT - 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 | 07-01-2010 |
| 20110138987 | PEDAL APPARATUS OF ELECTRONIC MUSICAL INSTRUMENT - A lever is supported by a lever supporting portion. The lever is urged by a first spring and a second spring. The urging force of the first spring varies over the entire operational range of the lever. The second spring and a third spring are provided serially through a movable supporting member. The displacement of the movable supporting member is restricted by a fixed supporting member. If the urging force of the second spring exceeds the urging force of the third spring, the restriction on the displacement of the movable supporting member is removed. Therefore, the present configuration provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano. | 06-16-2011 |
| 20130180377 | MUSICAL INSTRUMENT EQUIPPED WITH A PEDAL, AND METHOD THEREFOR - In a player piano, a position sensor is provided cm an end portion of a lifting rail for detecting a vertical position of the lifting rail. In storing performance data of dampers, a signal output from the position sensor and indicative of a vertical position of the lifting rail is converted into a digital signal, and a position value indicative of the position of the lifting rail is generated on the basis of the digital signal and stored into a buffer. A conversion section converts the position value into a vertical position of a pedal rod connected to a damper pedal, and the thus-converted vertical position is converted, into a control value which a control change message of the damper pedal in MIDI-format data can take. The control value obtained in the aforementioned manner can be recorded into a recording medium as performance information. | 07-18-2013 |
| 20140182444 | METHOD AND DEVICE FOR IDENTIFYING HALF POINT OF PEDAL ON KEYBOARD MUSICAL INSTRUMENT - A key depression (i.e., string striking) is performed while a pedal is kept at a set non-key-depressed-state corresponding position (a rest position of a hammer). A string striking velocity immediately before string striking and a string releasing velocity immediately after the string striking are detected, and a coefficient of rebound is calculated on the basis of the detected velocities and stored in association with the current value of the rest position of the hammer. Similar operations are repetitively performed with individual ones of different rest positions of the hammer, wherein each of the different rest positions of the hammer corresponding to each of a plurality of stroke positions within one stroke of the pedal. Thus, a distribution curve of the coefficients of rebound detected in association with the plurality of stroke positions is obtained and a half point of the pedal is identified based on the distribution curve. | 07-03-2014 |
| 20150096425 | Piano Extended Soft Pedal / CIP - A piano selectively playable in normal and soft modes has multiple piano keys and actions, including a wippen assembly, and multiple piano hammers. A soft pedal system includes a soft pedal and a hammer rest rail mounted for movement between normal and soft mode positions. A piano key lift rail is mounted for movement between a normal mode position spaced from lifting contact with the keys and a soft mode position in contact with and lifting the keys and the wippen assemblies. A soft pedal linkage assembly between the soft pedal and the hammer rest rail and piano key lift rail, upon actuation of the soft pedal, causes movement of hammer rest rail and piano hammers, and movement of the piano keys and the wippen assemblies, between normal and soft mode positions, in gap-closing motion. | 04-09-2015 |
