Abstract

PROBLEM TO BE SOLVED: To enlarge the adjustment width to a rear part of a bridge main body for supporting at least a first string by projecting the low-frequency sound string side end part of the screw attaching part of a bridge base to the rear part more than the other parts. SOLUTION: To the screw attaching part 30B of the bridge base, an adjusting screw 9 for moving and adjusting the respective bridge main bodies in back and forth directions is attached. Then, at the screw attaching part 30B, the low-frequency sound side end part 30B-1 corresponding to the first string is projected to the rear part for an appropriate dimension more than the part 30B-2 corresponding to second-sixth strings and the adjusting screw 9 of the bridge main body for supporting the first string is attached to the low-frequency sound side end part 30B-1. Also, long grooves 8a and 8b for inserting the lower ends of two height adjusting screws 7 for supporting the bridge main body 6 of the low-frequency sound side end part 30B-1 are shifted to the rear part more than the other long grooves 8 for the projected dimension of the low-frequency sound side end part 30B-1 and formed. Thus, the adjustment width to the rear part of the bridge main body 6 is enlarged and the difference of the adjustment amount of an octave interval is made small.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bridge for an electric guitar.

[0002]

2. Description of the Related Art A string of an electric guitar has one end locked by a bobbin provided on a neck body and the other end locked by a bridge provided on a surface of a body. The bridge includes a bridge body that supports the strings, and moves the bridge body in the direction in which the strings are stretched to set the effective string length of the strings and obtain a predetermined pitch. In addition, the bridge body is provided so as to be adjustable in height, so that the strings do not make chatter due to contact with Fred, or the relative positional relationship between the strings and a pickup device that converts the vibration of the strings into an electric signal. And adjust the tone and volume.

FIG. 4 is a plan view of a bridge in a conventional electric guitar, and FIG. 5 is a sectional view taken along line VV of FIG. The bridge 1 includes a bridge base 4 fixed to a surface of an electric guitar body 2 with a plurality of screws 3. The bridge base 4 includes a base 4A fixed to the body 2 by being formed in an L shape in a side view, and a screw mounting portion 4B protruding upward from a rear end of the base 4A. Five bridge bodies 6 each supporting the bridge 1 side end of each string 5 (5a to 5e) above 2A are 2
It is arranged via a height adjusting screw 7 of the book. The height adjustment screw 7 is screwed into a vertical screw hole formed through the end of the bridge body 6 and moves into a long groove 8 whose lower end is elongated in the direction in which the string 5 is formed on the upper surface of the base 4A. Is inserted as possible. Therefore, when the height adjusting screw 7 is rotated, the bridge main body 6 moves up and down along the height adjusting screw 7, and the height of the support point of the string 5 can be adjusted.

The screw mount 4B of the bridge base 4 has
An adjusting screw 9 for moving and adjusting the bridge body 6 in the direction in which the string 5 is stretched is attached. The adjusting screw 9 is rotatably inserted into an insertion hole 10 formed in the screw mounting portion 4B while allowing a small amount of play in the vertical direction, and has a tip portion formed near one end of the bridge body 6. It is screwed into the proper screw hole. Therefore, when the adjusting screw 9 is rotated, the bridge main body 6 moves in the front-rear direction along the adjusting screw 9, whereby the effective chord length of each string 5, that is, the nut (upper piece) provided on the neck main body is not shown. The length of the string between the bridge body 6 can be freely adjusted. The adjusting screw 9 is provided with a compression coil spring 11 for urging the bridge body 6 toward the neck body.
Further, the end of the string 5 on the bridge 1 side is inserted and locked in a string insertion hole (not shown) provided in the screw mounting portion 4B.

In such a bridge 1, distances a 1, a 2,... From the screw mounting portion 4 B to the bridge body 6.
an is usually set to be longer from the lower string side to the higher string side (a 1 <a 2 <... an
). For this reason, the height adjusting screw 7 of the bridge main body 6 that supports the first string 5a on the bass side is located near the rear end of the long groove 8, and has an effective string length longer than the other height adjusting screws 7. The adjustment width is the shortest when it is lengthened.

[0006]

As described above, in the conventional electric guitar, the distances a1, a2,... An from the screw mounting portion 4B of the bridge base 4 to each bridge body 6 support the first string 5a. Is set to be shortest in the low-frequency side bridge body 6 and longest in the high-frequency side bridge body 6 that supports the fifth string 5e.
The adjustment width in the direction of increasing the effective string length of the first string 5a, particularly the first string 5a, is short, and the adjustment amount of the octave interval is reduced to all strings 5a.
There was a problem that can not be aligned. Further, the same spring is used as the compression coil spring 11 for urging each bridge body 6, but in this case, the first string 5a
, The compression amount is the largest due to the distance a, so that the stress on the bridge body 6 is relatively largest as compared with the other compression coil springs 11. Therefore, the adjustment screw 9 of the bridge main body 6 corresponding to the first string 5a is rotated to move the bridge main body 6 up and down to set the koji angle of the string (the bending angle of the string portion bent by the bridge main body) to a desired angle. When you need a lot of power. It should be noted that the Koji angle affects important factors such as sustain and attack.
Therefore, in order to solve such a problem, the bridge stand 6
It is conceivable that the distance a1 between the bridge body 6 of the first string 5a and the screw mounting portion 4B is increased by increasing the length in the front-rear direction, but in this case, the bridge 1 itself becomes large and heavy. Not preferred. For the compression coil spring 11, it is conceivable to use springs having different spring constants. However, in such a case, the number of types of springs increases, which makes component management and assembly work cumbersome, which is not preferable.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. It is an object of the present invention to change at least the first string by only partially changing the shape of a screw mounting portion of a bridge stand. An object of the present invention is to provide a bridge for an electric guitar in which the adjustment width of a bridge main body to be supported can be increased, and the koji angle of a string can be set to a desired angle.

[0008]

In order to achieve the above object, the present invention provides a bridge base, a plurality of bridge bodies disposed above the bridge base corresponding to the respective strings, and supporting the strings, In a bridge for an electric guitar, comprising a height adjusting screw for adjusting the height of the bridge main body and an adjusting screw attached to a screw mounting portion of the bridge base for moving and adjusting the bridge main body in a string extending direction, The low string side end of the screw mounting portion of the bridge stand to which the adjusting screw corresponding to at least the first string is attached projects from the portion to which the other adjusting screw is attached to the side opposite to the neck body. It is characterized by.

In the present invention, the lower string side end of the screw mounting portion of the bridge stand projects rearward from other portions.
Therefore, it is possible to increase at least the backward adjustment width of the bridge main body that supports the first string.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. 1A and 1B are a front view and a side view of an electric guitar having a bridge according to the present invention, FIG. 2 is a plan view of the bridge, and FIG. 3 is a side view of the bridge. The same components as those shown in the section of the prior art are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. In FIG. 1, the electric guitar 20
Is a solid-type body 2, a neck body 22 joined to one end of the body 2, and a vibration provided at the center of the upper surface of the body 2 in the width direction to convert vibrations of the strings 5 (5a to 5f) into electric signals. Pickup devices 23 and 24, a bridge 1 for locking one end of each string 5, and a spool 26 provided on a head portion 22 a of a neck body 22 and locking the other end of each string 5.
And a switch 27 provided on the upper surface of the body 2.

In FIGS. 2 and 3, the bridge 1 is
A bridge base 30 fixed to the upper surface of the body 2 by a plurality of screws is provided. The bridge base 30 is formed into an L shape in a side view by bending a metal plate or the like, so that a base 30A fixed to the body 2 and a base 30A are formed.
And a screw mounting portion 30B that rises vertically above the rear end. Above the base 30A, a bridge body 6 supporting one end of the string 5 is provided with two height adjusting screws 7.
It is arranged through. The lower end of the height adjusting screw 7 is movably inserted into a long groove 8 formed on the upper surface of the base 30A in the direction in which the strings 5 are stretched.

The screw mounting portion 30B of the bridge base 30 includes
Adjusting screw 9 for moving and adjusting each bridge body 6 in the front-rear direction
Is installed. Therefore, a screw mounting hole (not shown) through which each adjustment screw 9 is inserted is formed in the screw mounting portion 30B at the same pitch as the pitch of the strings 5 in the longitudinal direction of the screw mounting portion 30B. The screw attachment portion 30B does not form the same continuous surface over the entire length, but forms a discontinuous surface so that the lower string side end portion 30B-1 corresponding to the first string 5a has the second surface. The bridge main body 6 protrudes from the portion 30B-2 corresponding to the sixth string 5b to 5f appropriately in size, and supports the first string 5a at the bass side end 30B-1.
Adjustment screw 9 is attached. The first and second long grooves 8a and 8b from the left end into which the lower ends of two height adjusting screws 7 for supporting the bridge main body 6 of the bass side end portion 30B-1 so as to be adjustable in height are inserted. Low end 30B
It is formed so as to be shifted rearward from the other long grooves 8 by a protrusion dimension of -1. Other configurations are the same as those of the conventional bridge shown in FIGS.

In the bridge having such a structure, the lower string side end 30B-1 of the screw mounting portion 30B of the bridge stand 30 projects rearward from the other portion 30B-2, that is, the side opposite to the neck body 22. The lower end 30
The distance a1 between B-1 and the corresponding bridge body 6 can be increased. Therefore, the adjustment width of the bridge body 6 to the rear is increased, and the difference in the adjustment amount of the octave interval can be reduced. Also, since only the bass string side end 30B-1 is projected rearward, it is not necessary to make the entire bridge stand 30 large. Furthermore, a1
Is larger, the amount of compression of the compression coil spring 11 for urging the bridge body 6 is reduced, and the elastic force on the bridge body 6 can be weakened. It can be operated with substantially the same force as when operating the adjusting screw 9.

In the present embodiment, only the low string side end 30B-1 of the screw mounting portion 30B is projected rearward. However, the screw mounting portion 30B is formed in a step-like shape so that the screw mounting portion 30B extends from the screw mounting portion 30B. It is also possible to make all the distances to each bridge body 6 equal. However, in practice, it is sufficient to increase the rearward adjustment width only for the adjustment screw 9 of the first string 5a, but if necessary, project the projections corresponding to the second and third strings. Is also good.

[0015]

As described above, the bridge of the electric guitar according to the present invention comprises a bridge base, a plurality of bridge bodies disposed above the bridge base corresponding to each string and supporting the strings, In a bridge for an electric guitar, comprising a height adjusting screw for adjusting the height of the bridge main body and an adjusting screw attached to a screw mounting portion of the bridge base for moving and adjusting the bridge main body in a string extending direction, The low string side end of the screw mounting portion of the bridge stand to which the adjusting screw corresponding to at least the first string is attached protrudes from the portion where the other adjusting screw is attached to the side opposite to the neck body. Therefore, the adjustment width of the bridge main body that supports the first string can be increased without increasing the size of the entire bridge stand. Therefore, it is possible to reduce the difference in the adjustment amount of the octave pitch from the other bridge main bodies.
In addition, even if the springs are all the same, the amount of compression of the spring that biases the bridge body that supports the first string can be reduced. Can be operated with substantially the same force as when operating the adjustment screw.
