Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a tremolo device for an electric guitar and an electric guitar.

[0002]

2. Description of the Related Art In an electric guitar equipped with a tremolo device,
It is designed to prevent the pitch (tuned state) from changing due to changes in the string tension (pitch) during tremolo performance. For example, in the electric guitar described in USP No. 4171661, the strings are locked by bolts and pressing members in the saddle portion of the tremolo device on the body surface. A string fixing member for fixing the strings is also provided on the nut portion near the head portion. Therefore, even if you perform a tremolo performance, it is difficult for the tuning to go wrong. However, if the string is locked at the nut, it will be difficult to tune it with a bobbin, so even if the string is locked with the nut, fine tuning is possible even after locking the string at the saddle. A fine tuning device is provided.

FIG. 9 is a perspective view showing a conventional tremolo device for an electric guitar capable of fine tuning.
10 is a cross-sectional view of the tremolo device taken along the line I-I in FIG. The tremolo device includes a base plate 60 that is swingably attached to a body surface, and a string 15 of an electric guitar that is held by the base plate 60.
A bridge saddle 67 for holding the tuneable is provided, and is configured as follows.

Below the base plate 60, as shown in FIG. 10, a tremolo block 45 extends downward. A spring is stretched between the tip of the tremolo block 45 and a bracket fixed to the body. A knife edge portion 61 provided on the nut side end portion of the base plate 60 is hooked on the two stud bolts 62 planted in the body. Then, the base plate 60 is supported by the stud bolt 62 at the knife edge portion 61 while the tension between the string 15 and the spring at the tip of the tremolo block 45 is balanced. for that reason,
When a tremolo arm (not shown) is swung up and down, the base plate 60 swings around the knife edge portion 61 as a fulcrum, and the pitch of the entire string can be changed.

The bridge saddle 67 is a saddle holding member 6
3, a fixing bolt 64 for fixing the saddle holding member 63 to the base plate 60, and a saddle 65 supported by a pin 66 on a bearing 63a of the saddle holding member 63 and held so as to be vertically swingable.

The saddle holding member 63 has a slot 6 at the front.
3b is formed, and a fixing bolt 64 screwed vertically to the base plate 60 is inserted into the slot 63b. Then, the fixing bolt 64 is attached to the base plate 60.
The slot 63b is tightened and fixed by the head of the fixing bolt 64 by being screwed in. By loosening the fixing bolt 64, the saddle holding member 63 can be displaced forward and backward,
Harmonic tuning is possible.

The saddle 65 is supported by a pin 66 arranged at the rear end of the saddle holding member 63 so as to be swingable in the vertical direction, and is arranged rearward. The rear end of the saddle 65 is bent obliquely downward, and the opening groove 60 of the base plate 60 is
A rod-shaped rotation adjusting rod 65c is extended substantially horizontally behind the base plate 60, penetrating the portion a. A plate spring 47 fixed to the base plate 60 is in contact with the lower part of the rotation adjusting rod 65c from below to urge the rotation adjusting rod 65c upward.

On the upper surface of the front portion of the saddle 65, a chord fixing recess 65a having a rectangular shape in plan view is formed in a direction slightly inclined forward from the vertical. A rectangular parallelepiped clamp pad 68 is disposed in the string fixing recess 65a with a gap in the front-rear direction. One end of the string 15 whose end ring is cut is sandwiched between the clamp pad 68 and the front side wall of the string fixing recess 65a. Also, the string fixing recess 65a
The string fixing bolt 69 is screwed into the screw hole penetrating rearward from the rear side wall of the rear side, and by tightening the string fixing bolt 69, the clamp pad 68 is biased from the rear side, and the string 1
Lock 5 When replacing the strings 15,
By rotating the head portion provided behind the string fixing bolts 69 counterclockwise with a tool, the string fixing bolts 69 are moved rearward and the clamp pad 68 is urged. When released, the string 15 is released from the locked state.

The base plate 60 is formed so that its rear portion is bent obliquely upward and the opening groove 6 provided therein is formed.
The rotation adjusting rod 65c of the saddle 65 is penetrated between 0a with a gap around it. A fine tuning bolt 70 is screwed into the rear end portion 60b of the base plate 60 obliquely downward. The lower end portion of the fine tuning bolt 70 is in contact with the upper surface of the rear end portion of the rotation adjusting rod 65c that is biased upward by the leaf spring 47. When the string 15 is attached, the saddle 65 applies a force by the tension of the string 15 so as to rotate counterclockwise in FIG. 10 about the pin 66, in other words, the rear end of the rotation adjusting rod 65c is raised. ing. Therefore, by rotating the fine tuning bolt 70 and moving its lower end up and down, the vertical position of the rear end of the rotating adjustment rod 65c can be changed, and as a result, the tension of the string 15 can be adjusted. Can be tuned.

[0010]

In the tremolo device for an electric guitar constructed as described above, the head of the string fixing bolt 69 is rotated counterclockwise as viewed from the rear side to be retracted so that the string 15 is unlocked. There was a problem that the clamp pad 68 might fall off when releasing. If this drop occurs, not only is the recovery work troublesome, but the clamp pad 68 may be lost because it is a small part. In this case, there is a problem that the strings 15 can no longer be fixed to the saddle 65, and the electric guitar cannot be used.

When the head of the string fixing bolt 69 is rotated counterclockwise as viewed from the rear to release the string 15 from the locked state, the string fixing bolt 69 is rotated from the rear with a tool. I have to move it. Therefore, the rear portion of the base plate 60 and the fine tuning bolts 70 and the like arranged here interfere with the tool and the string fixing bolts 6
There is a problem that it is difficult to rotate the 9 and the work of attaching and detaching the strings 15 is very troublesome.

According to the fifth aspect of the invention, the strings can be stably and reliably held without being damaged. According to the invention of claim 6, when the clamp pad tilts, the fulcrum is in line contact with the saddle, so that the fulcrum does not rattle and the string can be clamped stably.

According to the invention of claim 7, even when the clamp pad is tilted, it is possible to prevent the through hole of the clamp pad and the string fixing bolt from interfering with each other, so that the string can be detached and attached smoothly.

According to the eighth aspect of the present invention, even when the clamp pad is tilted, the head of the string fixing bolt makes a line contact with the clamp pad and stably urges the string downward so that the string is stabilized. Can be held.

According to the ninth aspect of the present invention, the clamp pad is displaced upward by the urging force of the elastic body only by loosening the string fixing bolt, and a gap is formed between the saddle and the clamp pad. It becomes easy to insert it between the saddle and the clamp pad, and the strings can be smoothly attached and detached.

According to the tenth aspect of the invention, even when the string fixing bolt is loosened, the clamp pad does not fall off from the saddle. According to the invention of claim 11, the clamp pad can be regulated in the correct direction, and the tilt of the clamp pad can be properly performed. Further, it is possible to prevent the strings from falling off in the lateral direction.
