<p>The invention involves the upright piano mechanism allowing for adjustment of the response of a particular key (9). The upright piano mechanism referred to in this invention provides for separation of the damper (1) from the string (6) with an adjustable force that can be adjusted from the exterior of the upright piano referred to in this invention and is felt by the pianist as hardness and/or weight of the key in the second phase of its depression, which influences the feeling of the pianist when playing the piano.Instead of one damper lever associated with each key, the mechanism referred to in this invention includes an attachment (2a) with the damper (1) mounted on its upper end. The attachment (2a) is flexibly clamped in the carrier pole (5). Due to the operation of the spring wire (3), the damper 1 presses against the string (6). Part (2b), lying within the reach of the spoon (4) that is flexibly mounted in the axle (12). The axle (12) can be moved vertically up and down in the direction of the arrow A, which results in the fact that the force with which the arm (13) presses against the attachment (2a) is different when the spoon (4) presses against the attachment (2b). This provides for different responses of a particular key.</p> |
