RU2602959C2 - Stringed musical instrument capotasto with calibrating fingerholes for strings - Google Patents

Abstract

FIELD: acoustics.

SUBSTANCE: invention relates to capotasto for stringed musical instruments. Stringed musical instrument capotasto has a calibrated fingerholes for each string, the strings of a certain diameter are used. Especially this capotasto is suitable for electric guitars having rectilinear arrangement of the strings from the back nut to the point of contact with the axis of splitting. Fingerholes do not allow a string to fall out of the set place of a string in capotasto. In straight position of the strings from the back nut to the point of contact with the axis of splitting, calibrated capotasto does not worsen the sound of a musical instrument. Fingerholes for strings are made by sliding fit.

EFFECT: achieved technical result is in improvement of sound of a musical instrument due to long-term preservation of tuning system and increase in durability of the strings and a possibility not to use the strings clamp to capotasto in arrangement of strings from the back nut to the point of contact with the axis of splitting.

Description

The invention relates to stringed musical instruments, such as an electric guitar, and allows for a longer fixation of the system, prevents the detuning of the instrument while playing it and when using the tremolo mechanism.

The nut of a stringed musical instrument is known, having sector-shaped supports independent of each other for each string lying on an arc of a sector-shaped support, which within the working gap has the ability to effect angular movement. US patent 4915006 from 04/10/1990, CL. G10D 3/06. US Classification 84/314 N.

Known sill having independent from each other sector-shaped supports for each string lying on the arc of sector-shaped supports, which within the working gap has the ability to carry out angular movement, moreover, sector-shaped bearing strings made as a whole with a jumper and stand, and the angular movement of sector-shaped supports is elastic deforms the jumper, which plays the role of the center of rotation of the sector-shaped string support. RF patent No. 2361287.

A known method of preserving the string musical instrument, in which the strings are located in a straight line without inflection on the nut, and pressing the strings to the nut is carried out by a special device. RF patent No. 2367032.

In FIG. 1 depicts a string musical instrument - an electric guitar. In FIG. 2, 3 depict the proposed nut.

The stringed musical instrument electric guitar (Fig. 1), equipped with a tremolo mechanism, the strings of which 3 are stretched by the axes of the pegs 5, has a bar 4.

During playing the electric guitar using the tremolo mechanism (Fig. 1), the tension of the strings is weakened or strengthened, which entails the movement of the strings relative to the nut due to the elastic deformation of the strings. The greatest displacement will be on the string pulled by the axis of the collet 7 of the farthest farthest from the nut. one.

If the electric guitar has a motionless nut on the head of the neck, then when the tremolo mechanism operates, the string slips along the motionless nut. Due to the frictional forces and plastic deformation of the string on the nut, after changing the tension of the strings by the tremolo mechanism, the string does not return to its original position, the guitar is broken. In order to avoid disruption of the system, given the small amount of movement of the string relative to the nut of the head of the neck, it is advisable to use a calibrated nut with holes for the strings made in a sliding fit to the outer diameter of the strings. This nut is especially suitable for electric guitars having a straight-line arrangement of strings from the rear nut to the point of contact with the shaft axis. Also, the proposed nut is suitable for electric guitars with minimal kink of strings on the front nut. The holes do not allow the string to fall from the seat of the string on the nut. With a straight-line arrangement of strings from the rear nut to the point of contact with the axis of the split, the calibrated nut does not impair the sound of the musical instrument. The holes for the strings are made on a sliding fit, which guarantees the absence of string bounce on the front nut.

If an electric guitar with a tremolo mechanism is not equipped with a nut having calibrated hole for the strings, then with a straight arrangement of strings or with a slight bending of the strings within the elastic deformation on the front nut and when playing the guitar and when using the tremolo mechanism, the strings may fall out of the grooves of the front nut, and when the strings are bent on a nut due to friction forces and plastic deformation of the string, the tremolo system is not guaranteed to return to its original position. The instrument will be disturbed.

The proposed nut allows you to reduce the friction of the strings against the nut and exclude the possibility of falling strings from the nut. And when installed on a guitar with a rectilinear arrangement of strings, it allows you to abandon the mechanism of pressing the strings to the nut and eliminates the rattle of the strings against the nut, which contributes to the normal sound of the electric guitar and the preservation of the structure of the musical instrument.

The proposed nut has the following design (see Fig. 2, Fig. 3).

In nut 1, adapted to the size of the neck of the guitar, the seats for the strings are made in the form of holes (pos. 2). Holes with a diameter corresponding to a sliding fit to the outer diameter of each string.

The proposed nut works as follows.

When the tension of the strings is weakened or the strings are strengthened by the tremolo mechanism (Fig. 1), the sills 4 remain motionless. Strings 3 (Fig. 1) inserted into the calibrated holes of the proposed nut slide in the calibrated holes. At the same time, the sound of a musical instrument is improved by maintaining the musical instrument

It should be noted that professional guitarists use strings of a certain size. The size of the strings is determined by the outer diameter of each string. Therefore, the proposed nut corresponds to the musical instruments used by professional musicians.

Moving the strings relative to the nut on the head of the neck when using the tremolo mechanism while playing a musical instrument is tenths of a millimeter. Therefore, the proposed nut remains operational for a long time. However, the use of ordinary sills, on which the strings are bent, entails strong friction of the strings against the grooves of the sill and plastic deformation of the strings, which negatively affects the integrity of the musical instrument.

The design of the nut, as an option, can be made of plastic or metal.

The present invention compares favorably with known analogues. The possibility of strong wear along the line of contact between the strings and the sills is excluded. Also excluded the possibility of strings falling out of the seats for strings in the nut. Simplicity of manufacturing in comparison with analogues. The sound of a musical instrument is improved, the durability of the strings is increased, since the nut allows avoiding the plastic deformation of the strings on the nut and minimizes the kink of the strings and reduces the friction of the strings against the nut, which helps to preserve the structure of the musical instrument.

Claims (1)

A string of a musical instrument, fixedly fixed in the neck of a string musical instrument, having seats for each string, characterized in that the seats for strings are made in the form of holes into which strings are inserted, while the holes are made in a sliding fit to the outer diameter of the strings.
