Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a tremolo unit used in an electric guitar.

[Prior art]

When playing an electric guitar, it is necessary to make sure that the strings are properly tuned, the string height is adjusted, the octave is adjusted correctly, etc.

On the other hand, a tremolo unit changes the tension of the strings by arming it and changes the pitch, thereby changing the performance.

For this reason, even if an electric guitar is adjusted to a normal state before playing, the strings are stretched during arming, causing the guitar to be out of tune.

In order to correct this inconvenience, a device was devised that fixed the string at the bridge position, fixed the length of the string between the nut and the bridge, and had a device that finely adjusted the length of the string (Japanese Patent Application Laid-open No. 58 −163997).

However, with this tremolo unit, it is impossible to adjust the octave while the string tension is still applied to the bridge, so the octave adjustment is done through trial and error by repeatedly loosening or removing the strings and tensioning the strings. , you have to adjust the pitch, string height, etc.
It was extremely troublesome.

[Purpose of invention]

This idea was made based on the above circumstances, and the purpose is to provide a tremolo unit for electric guitar that allows fine adjustments such as octave adjustment, pitch adjustment, and string height adjustment with the strings still attached. be.

[Structure of the idea]

The purpose is to provide a base having a required number of string passage holes and a supporting member erected on the back, a piece installed on the upper surface of the string passage hole in this base, and a lower part of the piece in the base. a lever lever installed to be swingable on the base; and a fine adjustment screw threaded from the rear of the base in the direction of the string passage hole for adjusting the swing of the lever; L from the short side and long side
The string having passed through the string passage hole is latched on the short side, and the tip of the fine adjustment screw is brought into contact with the long side, and a knob is provided on the fine adjustment screw. This was achieved by positioning the knob below the upper surface of the support member.

[Explanation of Examples]

Hereinafter, embodiments of this invention will be described based on the drawings.

In FIG. 1, an electric guitar 11 includes a body 13 and a neck 17 extending from the body 13 to which strings 15, 15, . . . are stretched.
and the head 1 connected to the tip of this net 17.
9. T is a tremolo unit installed in the body 13. This tremolo unit T pitch-bends or pitch-bends six strings 15, 15, . . . at the same time. In addition,
Reference numeral 18 denotes a string locking device, which fixes the strings 15, 15, . . . in the vicinity of the nut 16.

The tremolo unit T will be explained in detail based on FIGS. 2 to 9.

In the figure, 21 is a base, 23 is a tremolo block integrally formed with the base 21, and 25 is a base 2.
This is the piece placed on 1.

In the base 21, 27, 27, . . . are string passage holes, and 29 is a support member erected at the rear of the string passage holes 27, 27, . Reference numeral 31 denotes a through hole, which is bored in the support member 29. An octave adjustment screw 33 is loosely fitted into this through hole 31. Also, 3
Reference numeral 5 denotes a fine adjustment screw, which is threaded from the back side of the base plate 21 toward the string passage hole 27 so as to pass through the fine adjustment screw. This fine adjustment screw 35 is used to adjust the swinging of a lever lever 41, which will be described later. 35a is a knob that rotates the fine adjustment screw 35. Since this knob 35a is located below the upper surface of the support member 29 on the base 21,
Since it is not exposed on the top surface of 9, there is no risk that the player's hand will come into contact with it and turn the fine adjustment screw 35 during performance, and it will not interfere with the performance. Note that 37 is an operating arm.

Next, in the tremolo block 23, 39,
39, . . . are penetrating long windows, which are formed in the vertical direction by the number of strings 15. This long through window 39 communicates with the string passage hole 27 of the base plate 21 described above.
Reference numerals 41, 41, . . . are lever levers pivotally supported via shafts on the long through windows. As is clear from FIGS. 8 and 9, the lever lever 41 has a short side 41a and a long side 41b integrally formed in an L-shape. The short side portion 41a is located below and has a locking groove 43 at its tip. This locking groove 43 locks one end of the string 15. Also, the long side 4
1b is located upward and has a protruding piece 45 at its tip. This projecting piece 45 is connected to the fine adjustment screw 35 described above.
The tips of the two are in contact with each other. If the ratio of the short side portion 41a to the long side portion 41b is approximately 1:5, it will be easier to turn the fine adjustment screw 35 with your fingers against the tension of the strings, and it will also be easier to turn the fine adjustment screw 35 with your fingers against the tension of the strings. Adjustment screw 35
cannot be easily rotated.

The bridges 25, 25, ... are placed above the string passage holes 27, 27, ... of the base 21. The bridges 25 have through holes 47, through which the strings 15, 16, ...
The octave adjustment screws 33, 33, ... are the above-mentioned octave adjustment screws, which are screwed into the backs of the bridges 25, 25, ... via compression springs 49, 49, ....
Therefore, by screwing the octave adjustment screw 33 against the back, the bridge 25 can be moved forward and backward.
is a string height adjustment screw threadedly attached to the bridge 25.

Next, the operation of this embodiment will be explained based on FIGS. 6 and 7.

In the figure, when the fine adjustment screw 35 is pushed out by screwing against the base 21, the lever lever 4
1 swings clockwise against the tension of the string 15.
Then, the string 15 locked to the short side portion 41a is pulled and is strongly stretched. Further, when the fine adjustment screw 35 is moved backward, the lever lever 41 swings counterclockwise, so that the string 15 is loosened.

[Effect of idea]

The tremolo unit for electric guitar according to this invention includes a base having a required number of string passage holes and a support member erected on the back thereof, a bridge installed on the upper surface of the string passage holes in the base, A lever lever is swingably installed at the bottom of the bridge on the base, and a fine adjustment screw is screwed from behind the base in the direction of the string passage hole and for adjusting the swing of the lever. , the lever has an L-shape consisting of a short side and a long side, and the short side latches the string that has passed through the string passage hole, and the long side holds the tip of the fine adjustment screw. Further, the fine adjustment screw has a knob, and the knob is located below the upper surface of the support member.

Therefore, if the strings become out of tune after the strings have been tensioned, you can make fine adjustments such as octave adjustment, pitch adjustment, string height adjustment, etc. while the strings are still tensioned. There is no longer a need for troublesome adjustments that involve repeated trial and error of loosening or removing the strings and tensioning the strings.

Furthermore, in the tremolo unit for electric guitar according to this invention, the lever is installed at the bottom of the bridge, and the knob of the fine adjustment screw is located below the top surface of the support member. Since the lever lever and the knob for the fine adjustment screw do not protrude from the surface of the tremolo unit, the player's hands do not come into contact with the lever and fine adjustment screw during performance, so they do not get in the way of playing, and There is no risk of turning the fine adjustment screw and messing up the fine adjustment.

Thus, the practical value of such a device is enormous.
