Abstract

FIELD: musical instruments.

SUBSTANCE: invention relates to devices for fastening the strings of musical instruments, such as guitars. The device consists of a bar of a special shape, which replaces the usual bottom ring, with through holes in it, through which tension nuts can move, on which the ends of the strings are attached. Nuts can be moved back and forth by means of screws screwed into them. The dimensions and shape of the holes are selected in such a way that the screw can only perform rotational movement, being constantly in a state when its head is pressed against the narrowing of the hole on the outer surface of the tool body, and the nut can only perform translational movement along the screw axis.

EFFECT: present invention will simplify the device for fastening the strings of a musical instrument by replacing the pegs with hardware, nuts and screws; improve the weight balance of the tool; reduce the dimensions of the tool.

Description

The invention relates to devices for fastening the strings of musical instruments, such as guitars.

At present, the most common is the traditional system of fixing and tuning strings with the help of pegs, on which the free end of the string is wound, and a stand, in the holes of which the end of the string with a metal washer is fixed. The pegs are located at the end of the neck, and the stand is located on the body of the instrument. The holes of the stand are smaller than the diameter of the washer fixed at one of the ends of the string, so the string is threaded into the hole with its free end, and when tensioned, it is fixed thanks to the washer.

The disadvantage of the traditional string fixing system and its main difference from the invention is the need to make a so-called “head” on the fretboard of a musical instrument, on which the tuning pegs are placed. The presence of a “head” on the neck leads to an increase in the size of the musical instrument, and also complicates the process of making the neck.

The standard solution for fastening the second end of the string is that it is fixed in the stand (bridge) on the upper deck of the musical instrument, after which it rests on the nut fixed in the stand.

The present invention will simplify the device for fastening the strings of a musical instrument by replacing the pegs with hardware, nuts and screws; improve the weight balance of the tool; reduce the size of the tool.

This problem is solved due to the fact that the device consists of a bar of a special shape, which replaces the usual lower tong, with through holes in it, through which tension nuts can move, on which the ends of the strings are attached. Nuts can be moved back and forth by means of screws screwed into them. The dimensions and shape of the holes are selected in such a way that the screw can only perform rotational movement, being constantly in a state when its head is pressed against the narrowing of the hole on the outer surface of the tool body, and the nut can only perform translational movement along the screw axis.

The advantages of the proposed device are as follows:

1) the rejection of the standard peg mechanics in favor of the fastening and tensioning mechanism through the lower ring leads to:

- cheaper manufacturing and improved maintainability, since the pegs are replaced with hardware (nuts and screws);

- improving the balance of the weight of the tool. The center of gravity shifts towards the bottom of the body, as a result of which the guitar does not "peck" the neck, it is easier to hold it in your hands, sitting and on weight, the comfort of playing increases. This is especially true for bass guitars with a long neck;

- reduction of dimensions of the tool, simplification of transportation;

- reducing the likelihood of damage to the instrument (for many guitars, the headstock is the weak point if it is made at an angle to it);

2) execution of fastening of strings through the bottom ring leads to:

- change in the directions of the moments of forces acting on the bridge and the top deck when the strings are tensioned in the direction of a more gentle distribution of them: the possibility of deformation of the top deck and separation of the bridge from it disappears;

- reduction in the cost of manufacturing the instrument due to the simplification of the lattice of the upper soundboard: a complex system of springs and a futor in the area of the stand / bridge can be completely replaced by a single spring located directly under the bridge.

The essence of the proposed device for fastening the strings of a musical instrument is illustrated by the drawing, figure 1, where:

1 - string;

2 - nut;

3 - bridge;

4 - upper deck;

5 - futor;

6 - elongated nut;

7 - lower klets;

8 - hex head screw;

9 - lower deck.

The proposed technical solution is not known from available sources of information in the field of musical instruments, it can be practically implemented in production, that is, it meets the patentability criteria.

Claims (1)

The device for fastening the strings of a musical instrument includes a bottom ring with a shape as in figure 1, with through holes, along which the nuts-tensioners of the ends of the strings move forward by means of the rotational movement of the screws, and the screw heads are pressed against the narrowing of the hole on the outer surface of the instrument body, the top the deck of a musical instrument has holes for the passage of strings.
