摘要： A bat for an upright piano is provided for ensuring stable swinging movements of a hammer to generate a proper piano sound even if a hammer assembly has the centroid which is laterally asymmetric about a center pin. The bat for an upright piano is supported by the center pin having a circular cross section and arranged horizontally in a bat flange, in order to swing a hammer to cause the same to strike a string. The bat comprises a bat body integrally formed with the hammer, and having a linear pin holding groove in a back surface thereof, and a metal plate having a linear pin retaining groove in one side thereof, and attached to a back surface of the bat body such that the pin retaining groove extends in parallel with the pin holding groove, wherein the bat is pivotally supported by the center pin while the center pin is in engagement with the pin holding groove and the pin retaining groove, and the center pin is sandwiched between the bat body and the metal plate.

摘要： There is provided an action part for a piano, which has higher rigidity than that of an action part made only of a synthetic resin, while maintaining advantageous effects as provided by the use of the synthetic resin, thereby making it possible to obtain the sound volume with a smaller key depression energy, and enhance responsiveness of the action. The action part is pivotally moved along with depression of key to thereby transmit key depression energy generated by depression of the key, to a hammer. The action part is formed by a molded article of a thermoplastic resin that is molded by a long fiber process and contains long fibers for reinforcement.

摘要： A shank flange for use in a piano for supporting a hammer which makes a pivotal movement in response to depression on a key. The shank flange comprises a molding made of thermoplastic resin containing long fibers for reinforcement. The molding is molded by a long-staple method. The long fibers are carbon fibers. The shank flange excels in homogeneity and dimension stability, and has a high rigidity which can assure a smooth and stable action of the hammer. Also, dust and the like can be prevented from sticking to the shank flange and its surroundings, thus maintaining a precise action of the hammer and an aesthetically good appearance around the shank flange.

摘要： A back check for a piano is provided for locking a returning hammer in a pivotal movement without fail and for saving the manufacturing cost. The back check is used for locking the hammer in a pivotal movement for returning after it has struck a string to prevent the hammer from rebounding. A back check, disposed at a location at which the hammer is locked, extends in a vertical direction, and has an adhering surface which rises in a central portion thereof in the vertical direction. An under felt is adhered on the adhering surface of the back check body. A sheet-like cushion material, which is adhered to the back check body to cover the under felt, is formed with a locking surface in a predetermined curved shape conformal to the adhering surface for locking the hammer.

摘要： An action for a keyboard-based musical instrument is provided for preventing action parts made of a synthetic resin from being charged to eliminate stains due to dust and motes in the air attracted by static electricity. The action is composed of a plurality of action parts coupled to one another, including a hammer. The action actuates in response to depression on a key to swing the hammer which strikes a string. At least one of the plurality of action parts is made of a synthetic resin which has electrical conductivity at least on a surface thereof.
