摘要： The purpose of the present invention is to provide an upright piano action mechanism that improves sound quality relating to dynamic range and the like and facilitates repetition of the same note on the keyboard of the upright piano and any form of key pressing such as repetition and play-ing at half-touch while playing at pianissimo and half touch with the damper pedal depressed. The action mechanism is configured to either reinforce the spring force of a single hammer butt spring or use two hammer butt springs. When using two hammer butt springs, a butt range cord is provided with a twisted part to cause the hook of the two hammer butt springs to be caught by a ring-shaped part at the tip of the twisted part and the twisted part. The action mechanism uses a material with excellent lubricity for a hammer butt skin while reinforcing the elasticity of a jack spring, and is provided with a rubber-based cushion having a protrusion made of an elastic material with a through-hole along the rear surface of a jack stop rail and the front and rear surfaces of a damper stop rail.

摘要： A piano selectably playable in normal and soft mode includes multiple piano keys and multiple piano actions associated with the piano keys. Each piano action includes a piano hammer assembly and a piano wippen assembly actuated by depression of a corresponding piano key. Also included are multiple piano hammers, each mounted for rotating movement and defining a forward throw direction toward one or more corresponding piano string, and driven by a corresponding piano wippen assembly to transmit force applied to an associated piano key. One bridle strap, in a set of bridle straps, connects a piano hammer to a corresponding piano wippen assembly. A key lifting assembly in engagement with the piano keys and an associated bridle strap under tension cooperatively bring corresponding piano keys and piano wippen assemblies together in gap-closing movement.

摘要： Disclosed is an action for an upright piano capable of expressing rich tone variation and improving the continuous press performance of the same key. In the action (1) for an upright piano, there are formed a guide member (67) fixed to a center rail (14) and continuing in the horizontal direction; and a member to be guided (73) sliding along the guide member (67). A hammer under rail (19) on which a hammer shank (45) abuts is affixed to a hammer rail (18), and butt flanges (41) are affixed to the member to be guided (73). The member to be guided (73) is connected to a pedal (77) via an upthrust bar (81) and a balance (79) such that the member to be guided (73) is slid to the right or left with the force of working the pedal (77) by the player.
