Description

The invention relates to musical instruments and, in particular, to the so-called large white keys of pianos, grand pianos and accordions, and is intended for people with partial or complete loss of vision, as well as for people with impaired coordination of movements.

A non-traditional universal piano keyboard is known, containing a number of large and small keys, and a number of small keys is solid, the keys of both rows are of the same color, and all 12 sounds of the octave are extracted on the keys of both rows alternately with a step of 1 semitone (RF patent 2357299, G10C, 3/12 , 2009).

A keyboard of a musical instrument is known, containing at least two sets of keys located close to each other, and the keys of similar tones and semitones of different octaves form groups, each of the groups includes the keys of the same notes from the note "Do" to the note " C" of various octaves (RF patent 2705143, G10C 3/12, 2019).

Known keyboard, key, method for outputting and changing characters on the keys of the keyboard of an electronic device, containing a controller, a data processing device and keys with key heads, configured to output characters to the keys with their corresponding functions, change the characters of each of the keys and their corresponding functions, characterized in that in the key head of the keyboard keys, a mini-display is placed, connected to the controller and the data processing device, the screen of which extends to the front surface of the key head (RF patent 2214619, G06F 3/00, 2003).

The closest in technical essence is a keyboard for reading (voicing) music without notes, including a piano keyboard of conventional design, with each key on its surface having a sound identification in the form of a three-digit code according to the structure: the first digit is the serial number of the octave (including incomplete ones) in the interval from 0 to 8, the second and third digits - the serial number of the sound in the octave (from Do) in the range from 01 to 12 (RF patent 2002112595, G10C 3/12, 2003).

A disadvantage of the known devices is the difficulty of using closely spaced and adjacent keys of notes by people with low vision and movement coordination disorders, as a result of which the fingers of users capture adjacent keys when pressed. At the same time, the keys of the derivative steps of the notes (sharp) do not have the disadvantage inherent in the keys of the notes due to the significant distance between them.

The technical result is to ensure error-free playing of a musical instrument for people with low vision and impaired coordination of movements.

The technical result is achieved by the fact that the note key of a musical instrument of piano design is provided with a key identifier, and the note key identifier is represented by a removable insert or removable insert, a blind slot is made in the note key corresponding to the shape of the removable insert or removable insert, with the possibility of placing the latter in the blind slot of the key notes.

The essence of the invention is illustrated by drawings, where in Fig. 1 shows a note key of a musical instrument of a piano design with a vertical slot for a removable insert with an outer surface in the form of a half-cylinder, top view; in fig. 2 - note key of a musical instrument of a piano design with a sagittal slot on the front and upper surface for a removable insert, top view; in fig. 3 - a note key of a musical instrument of a piano design with a vertical straight slot with a removable insert with a longitudinal rib in the upper part, a cross section; in fig. 4 - note key of a musical instrument of a piano design with a sagittal slot with one pair of guides with a removable insert in the form of a semi-cylinder on the key surface and a straight surface inside the key slot, cross section; in fig. 5 - note key of a musical instrument of a piano design with a sagittal slot with one pair of guides with a removable insert with a straight surface on the key surface and with a surface in the form of a semi-cylinder installed in the key slot, cross section; in fig. 6 - variants of removable inserts: with a pyramidal profile on one side and fine serrations on the other side; with a concave profile on one side and medium gear cutting on the other side; with a convex semicircular profile on one side and a large rectangular cut on the other side, front view; in fig. 7 - variant of the sagittal slot with two pairs of guides and a removable insert in the lower pair of guides, cross section; in fig. 8 - a variant of the sagittal slot with two pairs of guides and a removable insert in the upper pair of guides, cross section.

The note key 1 of a piano design musical instrument is provided with a key identifier, which is a removable insert 2 (Fig. 1) or a removable insert 3 (Fig. 2).

The removable insert 2 and the removable insert 3 are made of polymers of various structures, such as high-impact polystyrene, high- or low-density polyethylene, silicone, rubber, foamed polymers, carbolite, or metal.

The removable insert 2 and the removable insert 3 can be made from natural organic materials such as ivory, walrus bone, animal horns, wood, leather or felt.

Removable insert 2 is a replaceable part of the note key 1, installed in a vertical blind slot 4 (Fig. 1 and Fig. 3).

Removable insert 3 is an element inserted into a specially designated place for it in the form of a sagittal slot 4 with guides 5 under the longitudinal protrusions 6 of the removable insert 3 (Fig. 2, Fig. 4, Fig. 5, Fig. 7 and Fig. 8) .

The blind slot 4 corresponds in size and shape to the removable insert 2 and the removable insert 3.

In the case of making a blind slot 4 in the vertical plane of the note key 1, the walls of the slot 4 are made straight, corresponding to the size and shape of the removable insert 2 (Fig. 3).

When making a blind slot 3 in the sagittal plane, the keys of the note 1, in the slot 4 perform longitudinal guides 5 oriented in the sagittal plane.

Guide slots 5 4 are longitudinal grooves and can be represented by one pair (Fig. 4 and Fig. 5) or two pairs (Fig. 7 and Fig. 8), depending on the version of the removable insert 3 and its longitudinal protrusions 6.

At the same time, the longitudinal protrusions 6 of the removable inserts 3 correspond in shape and size to the guides 5 of the slots 4 and are made with the possibility of longitudinal movement in the sagittal direction of the longitudinal protrusions 6 in the guides 5.

The note key of the piano design keyboard is used as follows.

The user selects a removable inlay 2 with the desired shape and surface, for example, with a protruding longitudinal rib, half-cylinder, anti-slip grooves or a concave surface, and installs the removable inlay 2 in the slot 4 of the note 1 key.

At the same time, the half-cylinder (Fig. 1) or the longitudinal rib (Fig. 3) that rises above the note key 1 will become the approximate support of the user's finger and will not affect the neighboring note keys 1, and the anti-slip thread that rises above the note 1 key will not allow the fingers of the performer's hand to move to the side. to adjacent note keys 1.

The part of the insert 2 that rises above the note key 1 becomes separated from the adjacent insert 2 by a distance that protects against accidental pressing of the adjacent note key 1.

Removable insert 2, made with a concave surface rising above the key of note 1 (Fig. 6), will direct the finger of the brush to the center of the key of note 1, excluding accidental contact with adjacent keys of note 1.

If it is necessary to switch to a classic piano design key with a width of 23 mm, a removable insert 2 or a removable insert 3 is flush with the top surface of the note key 1.

When executing the note key 1 with a slot 4 with guides 5 made in the sagittal plane, the longitudinal protrusions 6 of the removable insert 3 are inserted into the guides 5 and moved into them until they stop.

If it is necessary to change the working surface of the note key 1, the removable insert 3 is turned over, which allows it to be used in two versions (Fig. 4 and Fig. 5).

If two pairs of guides 4 are made in the note key 1, then the removable insert 3 can be used in two versions: with installation in the upper pair of guides 5 (Fig. 8) and with installation in the bottom pair of guides 5 (Fig. 7), which allows not only change the elevation height of the removable insert 3 above the upper plane of the note key 1, but also set the removable insert 3 at the level of the upper plane of the note key 1. In the latter case, the options for installing removable inserts 2 and removable inserts 3 in the keys of note 1 are used in training for the transition users to the classic piano design keyboard.

The technical result of ensuring error-free playing of a musical instrument by people with low vision and impaired coordination of movements is achieved by the fact that the key of the musical instrument is provided with a key identifier in the form of a figured removable insert or a removable insert, and a slot is made in the note key, corresponding in shape and size to the key identifier with the possibility of placing the latter in the key slot.
