Description

[Detailed explanation of the invention] This invention relates to the structure of the tailpiece of the guitar.
In particular, it relates to a new tailpiece structure with an improved string tension structure.

With conventional tailpieces of this type, the ends of the guitar strings are latched onto and wound around a certain length to keep the strings under some tension, and then the tension of the strings is finely adjusted to tune the sound. In other words, it is common to perform tuning.

However, this invention attempts to propose a tailpiece structure that can easily perform string tensioning at a stage prior to the above-mentioned fine adjustment of the strings.

That is, the purpose of this invention is, firstly, to provide a structure that allows strings to be easily latched, and secondly, to provide a structure that allows for easy tightening of screws as in the conventional method. It is an object of the present invention to provide a novel structure in which strings can be stretched to a certain degree of tension with a simple mechanism, and only minor adjustments are required afterwards.

In order to achieve the above object, the guitar tailpiece structure according to this invention has a bridge base attached to the guitar body surface, a string fixing part configured to be adjustable in forward and backward movement, and a string fixing part configured to be adjustable from a substantially horizontal fixing position. The main body member is attached to the bridge base so as to be rotatable upward at a certain angle via the tip fulcrum, and the bridge saddle is disposed between the string fixing portion and the tip fulcrum of the main body member. Features.

This invented structure will be explained in detail below with reference to the attached drawings. Fig. 1 is an overall perspective view of the tailpiece portion of a guitar showing an example of this invented structure;
The figure is a longitudinal sectional view thereof, and FIG. 3 is a partial side view of the rear part of the main body member.

As shown in FIG. 1, the tailpiece structure of this invention consists of a bridge base 10, a main body member 20 for holding the strings which is rotatably mounted upward on the bridge base 10, and a bridge saddle 40. It is composed of

The bridge base 10 is attached to the surface of the guitar body, and in the embodiment, as is clear from the cross-sectional view in FIG. The hanging part 17 for swinging is a spring.

This bridge base 10 has a shaft pin portion 11 formed at its front portion and a locking partition portion 12 formed at its rear portion in order to attach a main body member 20 to be described below.

The main body member 20 is a member for fixing the string ends 8 and tensioning the strings 9 on the guitar body, and in particular has a string fixing part 30 configured to be adjustable in forward and backward movement. It is attached to the bridge base 10 so as to be rotatable upward at a certain angle from a substantially horizontal fixed position via the tip fulcrum 22.

The string fixing part 30 is attached to the ball end 8 at the end of the string 9, as can be better understood from the cross-sectional view in FIG.
It has an engagement notch 31 for locking, and is attached to the main body member 10 so as to be adjustable in the front and rear directions by a front and rear adjustment screw 32 screwed through a spring 33. Reference numeral 23 in FIG. 2 is a sliding portion of the string fixing portion 30 in the main body member 10, and 24 is a holding portion of the longitudinal adjustment screw 32.

Next, the rotation mechanism of the main body member 20 will be explained. As shown in the figure, the front half of the main body member 20 is formed in a bifurcated fork shape. 11. On the other hand, the rear part of the main body member 20 is equipped with the longitudinal adjustment screw 32 as described above, and as shown in FIG. A stopper member 35 is attached between the head 32a of the bridge base 10 and the head 32a of the bridge base 10 via a spring 34. are elastically engaged.

Therefore, the main body member 30 configured as above can be engaged by moving the stopper member 35 at the rear of the main body member 20 in the direction of the arrow in FIG. 3 from the substantially horizontal fixed position shown by the solid line in FIG. By solving this, it is possible to rotate upward at a certain angle using the tip bearing portion 23 as a fulcrum, as shown by the chain line in the figure.

Note that a stopper or the like may be provided at the fulcrum between the main body member and the bridge base so that the main body member 20 stops at that position after rotating through a certain angle.

A bridge saddle 40 is disposed between the string fixing part 30 and the tip fulcrum part 22 of the main body member 20, and supports the string 9. In the figure, numeral 42 is a fixing bolt for the bridge saddle, and 45 is a vertical adjustment screw for the bridge saddle.

Next, to explain the operation of this invention along with its effects, when tensioning the string, the main body member 20 is rotated upward and the ball end 8 at the end of the string is fixed to the string as shown by the chain line in FIG. This is done by hooking it onto the engagement notch 31 of the section 30, rotating it downward, and fixing it in a horizontal position. At this time, the string is pulled and taut by being rotated at a certain angle.
The strings are then strung. Needless to say, subsequent fine adjustments are made using the longitudinal adjustment screw 32. In the embodiment, the maximum rotation angle of the main body member is about 30 degrees, and the tensile length of the string due to the rotation is 1.5 to 4 mm. It is preferable to determine the rotation angle in advance according to the tensile length of each string.

As explained above, with the tailpiece structure according to this invention, the guitar strings can be tensioned to some extent by simply hooking the string end to the string fixing part of the main body member, rotating it downward, and fixing it in a horizontal position. The strings can now be strung quickly and with just one touch.

Therefore, not only is there no need for the troublesome work of winding the extra length of the strings as in the past, but it is now possible to concentrate on tuning the sound and perform it accurately. This idea is practical and extremely advantageous in actual performance.
