Problems solved by technology

The installation of the roller on the mating catch is relatively complex and practically difficult to retrofit into existing actions
In addition, a spring must be provided on the push rod for this purpose, which further increases the complexity
Furthermore, the adjustment is very difficult, as a small change in the position of the spring in the direction of the strike can completely lose control of the playing function, since the function of the action depends mainly on this member

Embodiment Construction

[0029] figure 1 The piano mechanism of the invention comprises a key 10 which acts on a linkage lever 4 through a key top post 16 and which lifts when the key 10 is operated. The movement of the linkage rod 4 is transmitted to the jack 3 , which has an action surface 3 a at its upper end, which is designed to cooperate with the hammer seat 14 . The hammer seat pads 14 are mounted on the hammer seat 1 and have, from the jack impact pad 11 , a curved application surface, which is configured to first receive the upward movement of the jack 3 and convert it into the hammer seat 1 . Rotational movement, ie so long, until the release lever 15 of the ram 3 hits the release button 19 and the ram 3 is pressed away from the ram impact pad 11 . From this moment on, the working surface 3a of the jack 3 slides on the hammer seat cushion 14, so that there is no more torque along the figure 1 is applied to the hammer seat 1 in a counterclockwise direction. This allows the hammers 2 to mov...

Abstract

The invention relates to a piano mechanical device comprising a plurality of keys (10). Each key controls a hammer (2). When the key (10) is operated, the hammer (10) knocks on a string (17) arranged vertically essentially. The key (10) is mechanically connected with an ejection rod (3). The ejection rod acts on a string pad (14) by utilization of an acting surface (3a). The hammer base pad (14) is arranged on a hammer base (1) connected with the hammer (2). The acting surface (3a) of the ejection rod (3) moves between the acting position and a release position along the hammer base pad (14). A first spring is arranged. The first spring carries out pretensioning of the ejection rod (3) towards the acting position according to the position of the hammer (2). Performing is improved through the following way: the first spring (5) interacts with the ejection rod (3) through a first roller (13).

Description

technical field [0001] The invention relates to a piano mechanism comprising a plurality of keys according to the preamble of claim 1 . Background technique [0002] The keys each operate a hammer, during which the hammer strikes on the strings arranged substantially vertically, and the keys are mechanically connected to the ejector rod, which acts on the hammer seat cushion by means of the action surface, the hammer seat The pad is arranged on the hammer seat connected to the hammer, the action surface of the jack is movable along the hammer seat pad between the action position and the release position, and a first spring is provided, and the first spring moves toward the hammer according to the position of the hammer. The ejector rod is pre-tensioned in the direction of the action position. [0003] In general, a piano mechanism is similar to a grand piano mechanism, but the difference is that the strings of the piano are arranged vertically and therefore do not operate t...
