Abstract

To provide a structure of a neck attachment angle adjusting mechanism capable of adjusting a string height by having a seesaw structure having a metal convex portion as a fulcrum at a neck attachment portion of a stringed musical instrument. A metal convex portion 4 is provided at the center of a neck mounting portion 3 of a stringed musical instrument, and the neck is formed by two or four mounting screws 5 and 6 sandwiching the metal convex portion 4 with respect to the neck 2 to be attached. 2 has a seesaw structure that adjusts the string height 11 of the stringed instrument by freely adjusting the mounting angle of the neck 2 by operating the mounting screws 5 and 6. [Selection] Figure 1

Description

  The present invention relates to a structure of a neck mounting portion having a variable angle adjustment function of a stringed instrument neck by a seesaw structure.

In a stringed instrument with a neck, the neck is attached or screwed to the body, and the neck mounting angle that determines the string height is fixed. The neck warp caused by string tension, neck wood drying, etc. The string height changes up and down, hindering performance.

  The problem to be solved is that a stringed musical instrument having a neck has a fixed neck, so that the string height rises and lowers due to warping of the neck, and this impedes the performance of the musical instrument.

  The main feature of the present invention is that a neck attachment angle adjustment function having a seesaw structure is added to the neck attachment portion in response to a change in string height due to neck warpage.

  The neck mounting angle adjustment mechanism with the seesaw structure of the present invention makes it possible to adjust the height of the string due to neck warping due to secular changes such as acoustic guitar with electric neck, electric guitar, electric bass, banjo, ukulele, body deformation, etc. In response to changes, the neck attachment angle adjustment mechanism attached to the heel makes it easy to lower the string height or raise the string height too low, making it easier for the performer to finger against the fingerboard Provide things.

1 is a structural cross-sectional view of a neck attachment angle adjustment mechanism with a seesaw structure in a stringed instrument. FIG. 2 is an overall perspective view of the stringed musical instrument, and is an installation view of a neck mounting angle adjustment mounting portion and a metal convex portion that provides a seesaw structure. FIG. 3 is an explanatory view showing a method of adjusting the neck attachment angle by the seesaw structure and showing an example of raising the string height. Example 1 FIG. 4 is an explanatory view showing a method of adjusting the neck attachment angle by the seesaw structure and showing an example of lowering the string height. (Example 2)

For the purpose of adjusting the vertical height of the string height due to neck warping or deformation, adjust the neck height by lowering the string height by giving the neck mounting part a seesaw structure, tightening the front mounting screw, and loosening the rear mounting screw. Realized the adjustment to increase the string height by loosening the front mounting screw and tightening the rear mounting screw.

FIG. 1 is an overall cross-sectional view of a stringed musical instrument, and is a structural view of a neck attachment angle adjusting attachment portion according to the seesaw structure of the present invention. It is supported by the convex part, and is fixed to the three neck attachment parts by 5 front attachment screws and 6 rear attachment screws, and the two neck bottom parts and the neck attachment parts are made of 4 metals. This shows that a slight gap is generated by the convex portion.

FIG. 2 is a perspective view of a stringed musical instrument, which is a neck attachment angle adjusting base installed at the neck attachment portion, and clearly shows four metal protrusions that provide a seesaw action.

FIG. 3 (Embodiment 1) is an adjustment to raise the string height. To reduce the attachment angle of the neck of 2, the front attachment screw of 5 is loosened, and at the same time, the rear attachment screw of 6 is tightened to the 11 fingerboard. Indicates to increase the string height.

FIG. 4 (Embodiment 2) is an adjustment for lowering the string height. In order to increase the attachment angle of the neck of 2, the rear attachment screw of 6 is loosened and at the same time the front attachment screw of 5 is tightened to adjust the string to 11 fingerboard Indicates to decrease the height.

Claims (1)

A convex part is provided in the center of the neck mounting part of the stringed instrument, and the neck is fixed with two or four screws before and after the convex part with respect to the neck to be mounted, and the neck mounting angle can be freely adjusted by operating this screw. Neck mounting angle adjustment mechanism with a seesaw structure that adjusts the string height of stringed instruments.
