Known keyboard mechanism of the piano with the vertical arrangement of the strings - the piano (IG Fadeev, CM. Allon "Repair and tuning of the piano and grand pianos", M .., "Light industry", 1973, pp. 72-73 - prototype) containing a key with a pilot located on three longitudinal bars, a hammer knot connected by a capsule with a gammerbank, a figure in which on the capsule is fixed to the capsule below the gammerbank a spring-loaded steeple with a figured protrusion in contact with the auslerian navel is fixed, there is a protrusion for the contact with the pilot from the bottom, a fenger wire and a loop are fixed at the front end of the figure, a fenger is screwed onto the fenger wire, a bentik is attached to the wire, the flexible hammer and figure are fastened on the wire, and the hammer and the figure are attached to the cable, the flexible wire is attached to the fender, the benger is attached to the cable, the flexible hammer and the figure are attached to the cable, and the benger is attached to the cable, the flexible wire and the figures are attached to the cable, and the benger is attached to the cable; the pin is attached to the Schulter, on top of the Schulter there is a Hammerschiel with a hammer glued in, on the front of the Schulter there is a protrusion with a pad on which the pinwheel rests; the rifle, coupled with an end hook with a loop of cord attached to the fork of the Schultern cap, the spring unclenches, throws the hammer away from the string. The whole hammer knot is bolted to the gammerbank, the gammerbank is fixed on the racks, the damper plate is fixed on the racks, the front panel of the hammer knot is mounted and fixed on the racks of the paired jumper hook, the metal hook is screwed onto the movable steering wheel, the movable steering wheel is connected to the movable steering wheel by a metal hook, the movable steering wheel is attached to a movable steering wheel with a metal hook, the movable steering wheel is attached to the movable steering wheel. the wand is connected to the left “piano” pedal; when you press the “piano” pedal, the ruleystick, turning, shifts all the hammers towards the strings — the prototype [1].

The disadvantages are: in a piano with horizontal strings - the impossibility of taking the una corda pedal on two strings to achieve the characteristic timbre of the sound of one string, the difficulty of achieving dynamic flexibility when working on the una corda pedal; in the piano with a vertical arrangement of strings - the lack of a pedal “una corda”, the lack of quality in the work of the pedal “piano”.

Disclosure of the invention.

The purpose of the invention: to create a piano-una corda pedal in the piano keyboard with a horizontal arrangement of strings, providing the pedal functions of the piano pedal, the una corda pedal on two strings, the una corda pedal on one string to expand the dynamic and timbre piano range; to create in the keyboard mechanism of the piano with the vertical arrangement of the strings the pedal “piano-una corda”, identical to the pedal “piano-una corda” in the keyboard mechanism of the piano with the horizontal arrangement of the strings.

This goal is achieved by the fact that the piano keyboard mechanism, which contains a knot that includes a hammer with an extended shank and a hammer, connected by a pin to the primer mounted on the gammerbank, is screwed into the gammerbank from below ausleser navel, a figure attached to a gammerbank, a pinwheel attached to a figure, a fenger attached to a key is attached to the key with an extended hammer shank, horizontally in a piano with a horizontal arrangement the strings are equipped with an additional piano-una corda pedal, combining the pedal functions of the piano pedal, the una corda pedal on two strings, and the una corda pedal on one string to expand the dynamic and timbre capabilities of the instrument; when the “piano-una corda” pedal is pressed, the first stage - the “pedal” pedal, which contacts the pedal rod with the bar mounted under the keyboard, the bar moves the key, figure, pinwheel, drum, hammerstil, hammer to the string, which reduces the swing of the hammer and provides piano extraction; the second stage - the “una corda” pedal by two strings, which is in contact with the pedal rod, transmits movement through the pedal rod to the barbell, the barbell wire, the wire moves the damper to the string, the damper suppresses one of the three strings, creates a hammer work through two strings, which ensures the ipa corda function; the third stage - pedal “ipa corda” on one string, which is in contact with the pedal rod, transmits movement through the pedal rod to the bar, the bar transmits movement to the wire, the wire moves another damper to the string, the damper suppresses the second string, creates a hammer work on one string, which provides una corda function.

In the well-known piano keyboard mechanism, this goal is achieved by the fact that, containing a key with a pilot, located on three longitudinal bars, a hammer knot connected by a capsule to a gammerbank, a figure is fixed to the gammerbank by a capsule, in which a spring-loaded capstan with a figured protrusion is attached to the capsule. with an auslerian navel, from the bottom of the figure there is a protrusion for contact with the pilot, in front of the hammer knot mounted and fixed on racks a ruleys of two parts paired to a movable ruleystik The metal hook is hooked, the movable steering wheel through the metal hook is connected to the lifting stick, the lifting stick is connected to the left pedal of the piano, while pressing the pedal of the piano the steering stick rotates and shifts all the hammers towards the strings In the piano with a vertical arrangement of strings, additional functions are installed in the piano pedal — the una corda function on two strings and the una corda function on one string to enhance the dynamic and timbre capabilities of the instrument, what forms the new ped l «piano - una corda», functionally similar to the pedal «piano - una corda» in piano with horizontal string arrangement; when you press the first stage “piano” of the pedal “piano - una corda” through the bolt-pull, rocker arm, stick, the movement is transmitted to the steering wheel, the steering wheel, turning, shifts all the hammers towards the strings, reducing the swing of the hammer, extracting the “piano”; when you press the second stage “una corda” on two strings through a bolt-pull, the movement is transmitted by a yoke, key with a rope, a cable with a tip barbell, a barbell wire, a damper wire, a damper suppresses one of the three strings, creates a hammer work on two strings, which provides the well-known una corda function; when the third stage of the piano-una corda pedal is pressed through the bolt-pull, the movement is transmitted by the yoke, key with a rope, the cable with the tip of the barbell, the barbell wire, the wire transmits motion to another damper, another damper suppresses the second string, creates a hammer work along one string That provides a new function - the function "una corda" on a single string.

A comparative analysis shows that:

in the well-known keyboard mechanism of a piano with a horizontal arrangement of strings, when the pedal “una corda” is pressed, the mechanic shifts to the side, the hammer hits two strings, the choir of two strings does not create the characteristic timbre of the sound of one string;

The technical solution of the “piano-una corda” pedal in a piano with horizontal strings contains a three-step function: the first step of the “piano-una corda” pedal ensures that the hammers approach the strings to perform the “piano” function; the second step of the piano-una corda pedal provides damping of one of the three strings for working the hammer on two strings to perform the una corda function on two strings; The third step of the “piano-una corda” pedal provides for killing another string with another damper to perform the “una corda” function on one string, which creates a timbre of the pure sound of one string without overtones of open strings according to the term “una corda” (on 1 string) in musical terminology. in the well-known keyboard mechanism of the piano with the vertical arrangement of the strings, when the piano pedal is pressed, the steering wheel, turning, moves all the hammers towards the strings and creates keyboard play, which interferes with the high-quality performance of the piano function.

The technical solution of the “piano-una corda” pedal in a piano with a vertical string arrangement contains a three-step function: the first step of the “piano- una corda ”ensures that hammers approach strings to perform the“ piano ”function without keyboard play; the second step of the piano-una corda pedal provides damping of one of the three strings for working the hammer on two strings to perform the una corda function on two strings; The third step of the “piano-una corda” pedal provides for killing another string with another damper to perform the “una corda” function on one string, which creates a timbre of the pure sound of one string without overtones of open strings according to the term “una corda” (on 1 string) in musical terminology.

With the advent of the “piano-una corda” pedal, equal mechanics in sound control and conditions for full disclosure of the dynamic and timbre potential of the piano are created in the piano and piano mechanics;

Thus, the declared pedal "piano-una corda" for piano meets the criterion of "novelty and significant differences."
