  FIG. 5 is a view for explaining the structure of the neck portion 20. This figure has shown an example of the attachment or detachment structure of the neck part 20 and the body part 10. As shown in FIG.

  The plate 210 is fixed to the back side of the neck portion 20 (the side opposite to the frets and fingerboard not shown). The plate 210 is made of a metal such as iron, and is fixed to the neck portion 20 with screws or the like. A female screw hole 211 corresponding to the male screw 240 is formed in the plate 210. Further, a hole 212 into which the tip of the male screw 240 is inserted through the plate 210 is formed on the back side of the neck portion 20.

  The body portion 10 is formed with a recess 230 for positioning and setting one end portion of the neck portion 20 on the body side. A plate 220 is fixed to the back side of the body portion 10 (the side opposite to the pickup 11). The plate 220 is made of, for example, a metal such as iron and is fixed to the body portion 10 with screws or the like. A hole 221 through which the male screw 240 passes is formed in the plate 220. Further, a hole 222 through which the male screw 240 passes through the plate 220 is formed on the bottom surface of the recess 230.

  The neck portion 20 is fixed to the body portion 10 by the male screw 240 and the female screw hole 211 in a state of being set in the recess 230. The head of the male screw 240 is formed with a handle that can be grasped with a finger and turned by a human. The user can easily turn the male screw 240 and can easily attach and detach the neck portion 20 to and from the body portion 10.

  In addition, if the neck part 20 can be attached or detached with respect to the body part 10, an attachment or detachment structure is not restricted to said structural example.

  FIG. 6 is a view for explaining the structure of the string fixing portion 30.

  The string fixing portion 30 is located at the distal end portion (the side far from the body portion 10) of the neck portion 20 and farther than the nut 21. The string fixing part 30 includes a string locking part 300, a base part 310, and a male screw 320.

  The string locking portion 300 is made of a metal such as iron, for example. The string locking portion 300 is formed with a hole 301 through which the male screw 320 passes in the string direction (direction substantially parallel to the string 50). Further, the string locking portion 300 is formed with a hole 303 through which one end of the string 50 passes. In addition, a female screw hole (not shown) corresponding to the male screw 302 is formed for each string 50 on the upper side of the string locking portion 300 (the same side as the front side of the neck portion 20). The hole is connected to the hole 303 from above (not shown).

  By tightening the male screw 302 with one end of the string 50 passing through the hole 303, the string 50 is vertically sandwiched between the tip surface of the male screw 302 and the lower surface of the hole 303, and one end of the string 50 Is locked to the string locking portion 300. For example, a wrench hole is formed in the head of the male screw 302. The user can easily attach / detach the string 50 to / from the string locking portion 300 by turning the male screw 302 to the left or right using a wrench.

  The base part 310 is made of, for example, a metal such as iron, and is fixed to the distal end surface of the neck part 20 with screws or the like. A female screw hole 311 corresponding to the male screw 320 is formed in the base portion 310 in the string direction. A hole (not shown) into which the tip of the male screw 320 is inserted through the female screw hole 311 is formed at the tip of the neck portion 20.

  The string locking portion 300 is fixed to the base portion 310 by the male screw 320 and the female screw hole 311 in a state where the corresponding hole 301 and the female screw hole 311 are positioned so as to overlap each other when viewed from the string direction. The head of the male screw 320 is formed with a handle that can be grasped with a finger and turned. The user can easily turn the male screw 320 and can easily attach and detach the string locking portion 300 to and from the base portion 310.

  One or more sets of convex portions and concave portions that fit into each other may be formed on the surfaces of the base portion 310 and the string locking portion 300 that face each other. In this way, it is possible to easily position the string locking portion 300 with respect to the base portion 310 and to prevent the string locking portion 300 from rotating around the male screw 320.

  If the string 50 can be locked, the structure of the string locking portion 300 is not limited to the above structure example. Moreover, if the string latching | locking part 300 can be fixed with respect to the neck part 20 so that attachment or detachment is possible, the attachment or detachment structure is not restricted to said structural example.

  FIG. 7 is a diagram (No. 1) for explaining the structure of the string adjusting unit 40. FIG. 8 is a diagram (part 2) illustrating the structure of the string adjusting unit 40. FIG. 9 is a diagram (part 3) illustrating the structure of the string adjusting unit 40. FIG. 10 is a diagram (part 4) for explaining the structure of the string adjusting unit 40.

  FIG. 11 is a diagram (part 1) illustrating the structure of the string locking portion 440. FIG. FIG. 12 is a diagram (No. 2) for explaining the structure of the string locking portion 440. FIG. 13 is a diagram (No. 3) for explaining the structure of the string locking portion 440. 11 to 13 focus on the structure related to one string, and the structures related to other strings are omitted.

  The string adjustment unit 40 includes a base part 400, a support part (which may be referred to as a “restriction part”) 410, and a string locking part 440. Each of these parts is made of a metal such as iron, for example.

  The base portion 400 is fixed to the surface of the body portion 10 on the side far from the neck portion 20 via the bridge 12. The base part 400 is fixed to the body part 10 with screws or the like, for example.

  The base portion 400 is formed of a flat plate portion 401 extending along the surface of the body portion 10 in a direction orthogonal to the chord direction, and a pair of flat plate portions 402 located at both ends of the flat plate portion 401 in the longitudinal direction. A female screw hole 405 corresponding to the male screw 420 is formed in the flat plate portion 402 in the string direction.

  The support portion 410 includes a flat plate portion 411 extending along the surface of the body portion 10 in a direction orthogonal to the chord direction, and a pair of thick portions 412 (L-shaped in the drawing) positioned at both ends of the flat plate portion 411 in the longitudinal direction. Or a portion that can also be referred to as an inverted L-shape). In the thick portion 412, a female screw hole 415 corresponding to the male screw 420 is formed at a position corresponding to the female screw hole 405. The female screw hole 415 penetrates in the string direction. Further, a pair of rod portions 416 that are inserted into the pair of holes 446 of the string locking portion 440 are provided at positions inside the female screw hole 415 of the thick portion 412.

  The support portion 410 is positioned so that the corresponding female screw hole 415 and the female screw hole 405 overlap when viewed from the string direction, and the position in the string direction can be adjusted by the male screw 420 and the female screw hole 415. Supported by part 400 (may be referred to as “connected”). That is, as the male screw 420 rotates left or right, the support portion 410 can move in the string direction.

  The support portion 410 is pulled to the neck side when the string locking portion 440 is pulled to the neck side by the tension of the string 50 with the string locking portion 440 set. However, the support part 410 is restricted from moving toward the neck side by locking the head of the male screw 420 in contact with the surface of the base part 400 where the female screw hole 405 is provided. It is fixed at a position in the chord direction according to the amount of rotation 420.

The male screw 420 is not formed with a male screw having a width (a width corresponding to at least the thickness of the flat plate portion 402 in the chord direction) on the side opposite to the tip in the chord direction. The diameter of the portion where the male screw is not formed is large enough to pass through the female screw hole 405. Further, a handle that can be grasped with a finger and turned by a human being is formed on the head of the male screw 420. The user can easily turn the male screw 420, and can easily move the support portion 410 in the string direction.

  The string locking portion 440 is formed by a flat plate portion 441 extending along the surface of the body portion 10 in a direction orthogonal to the string direction, and a thick portion 442 that opens one side of the neck side and surrounds the periphery of the flat plate portion 441. The In the thick part 442, holes 446 into which the pair of rod parts 416 are inserted are formed at positions corresponding to the pair of rod parts 416 of the support part 410.

  The string locking portion 440 is set on the support portion 410 by inserting the rod portion 416 into the hole 446 in a state where the corresponding hole 446 and the rod portion 416 are overlapped when viewed from the string direction. And the string latching | locking part 440 is pulled to the neck side by the tension | tensile_strength of the string 50, and the surface in which the hole 446 is formed contact | connects the surface in which the rod part 416 of the support part 410 is provided, While being locked to the support portion 410, the movement toward the neck side is restricted, and the position in the chord direction is fixed. Further, by inserting the rod portion 416 into the hole 446, movement in a direction deviating from the string direction (for example, a direction orthogonal to the string direction) is limited.

  A hole 443 that penetrates in the string direction is formed for each string 50 on one side of the thick portion 442 perpendicular to the string direction. The hole 443 has a diameter that can penetrate the male screw 462 of the bolt portion 460.

  The bolt part 460 has a head 461 and a male screw 462. The male screw 462 is inserted into the hole 443 through the spring 470 from the neck side. Then, it passes through the hole 443 and is inserted into the female screw hole 453 of the nut portion 450.

  A female screw hole 453 corresponding to the male screw 462 is formed in the nut portion 450. In the female screw hole 453, a female screw is formed in at least a part of the width in the string direction, and the diameter of the portion where the female screw is not formed is large enough to allow the male screw 462 to pass through.

  The bolt portion 460 is supported by the thick portion 442 of the string locking portion 440 through the spring 470 and the hole 443 so that the position in the string direction can be adjusted by the male screw 462 and the female screw hole 453. That is, when the nut portion 450 rotates left or right, the bolt portion 460 can move in the chord direction.

  Here, a hole 463 that penetrates the string 50 is formed in the head 461 and the male screw 462. The diameter of the hole 463 is such that the ball end 51 of the string 50 cannot pass through. The female screw hole 453 of the nut portion 450 also functions as a hole that penetrates the string 50. The diameter of the female screw hole 453 is large enough to allow the ball end 51 to pass through.

  That is, in a state where the string 50 is stretched, the ball end 51 is hooked and locked to the tip of the male screw 462. Accordingly, when the nut portion 450 is rotated and the bolt portion 460 is moved in the string direction, the position of the ball end 51 in the string direction is also moved, so that the tension of the string can be adjusted.

  The bolt portion 460 is pulled to the neck side when the ball end 51 locked to the tip of the male screw 462 is pulled to the neck side. However, the bolt portion 460 is restricted from moving toward the neck side because the nut portion 450 is locked in contact with the surface on the opposite side of the neck where the hole 443 of the thick portion 442 is provided. The position of the chord direction according to the amount of rotation of the part 450 is fixed.

  Both ends of the spring 470 are sandwiched between the surface on which the male screw 462 of the head 461 of the bolt portion 460 is provided and the surface on the neck side on which the hole 443 of the thick portion 442 is provided. Thereby, the wobbling of the male screw 462 starting from the hole 443 (the wobbling of the bolt part 460) is limited to a predetermined range.

  In the figure, a coil spring is used as the spring 470, but other types of springs, elastic bodies, and the like may be used as long as wobble can be limited.

  On the outer periphery of the nut portion 450, a slip stopper that can be gripped and rotated by a human finger is formed. The user can easily turn the nut portion 450 and can easily move the bolt portion 460 in the string direction.

  Thus, in the assembled state, the guitar 1 can move the entire string locking portion 440 in the string direction by moving the support portion 410 in the string direction, and collectively adjust the tension of all strings. it can. Moreover, the tension | tensile_strength of each string can be adjusted by moving the bolt part 460 of each string of the string latching | locking part 440 to a string direction.

  When carrying the guitar 1, for example, the body portion 10 (including portions other than the string locking portion 440 in the string adjusting portion 40) and the neck portion 20 (string locking in the string fixing portion 30). And the string locking part 440 and the string locking part 300 (can be handled as a single unit with the string 50 attached). And each part decomposed | disassembled can be accommodated in cases, such as case 500, for example.

  An example of a disassembling procedure when carrying the guitar 1 will be described. (1) The male screw 420 is rotated in a predetermined rotation direction, the support part 410 is moved to the neck side, and the string 50 is loosened moderately. (2) The male screw 320 is removed by rotating in a predetermined rotation direction, and the string locking portion 300 is removed from the base portion 310. (3) The string locking portion 440 is removed from the support portion 410. (4) The male screw 240 is rotated and removed in a predetermined rotation direction, and the neck portion 20 is removed from the body portion 10. For the assembly, for example, the above procedure may be reversed.

  As described above, according to one embodiment of the present invention, it is possible to provide a guitar having a structure that facilitates preventing breakage of strings and guitars and further improves convenience of storage and carrying.

  In addition, the above embodiment of this invention intends to illustrate the summary and scope of this invention, and does not limit it.

  For example, if the string locking portion 440 pulled to the neck side is locked by the support portion 410, the position, range, shape, number, etc. of the surfaces of the string locking portion 440 and the support portion 410 that face each other are in contact with each other. However, the present invention is not limited to the illustrated example. Further, the shape of each surface is not limited to a planar shape, and may be a three-dimensional shape.

  Further, for example, if the movement of the string locking portion 440 in a direction away from the string direction is restricted, the positions, sizes, shapes, numbers, etc. of the holes 446 and the rod portions 416 are limited to the illustrated example. Absent. Further, a rod portion may be provided in the string locking portion 440 and a hole may be provided in the support portion 410.

  Further, for example, the structure of the hole 446 and the rod portion 416 is not limited as long as the movement of the string locking portion 440 in a direction away from the string direction is limited. That is, one or more pairs of convex portions and concave portions that fit each other may be formed on the surfaces of the string locking portion 440 and the support portion 410 that face each other.

  Note that the present invention is not limited to guitars and can be applied to other stringed instruments such as basses.
