Abstract

PROBLEM TO BE SOLVED: To solve problems for example, in a conventional machine head for classic guitar, when a user stretches an arm to a guitar head part while holding a guitar body, a posture of the user becomes unnatural in appearance, and tuning during performance is limited, and because a knob part of the machine head is at the guitar head part, so that it is impossible to tune while stretching a user's back, and ears of a performing musician are in the vicinity of a sound hall, so that it is difficult to sense wave motion generated by sound difference and tune.SOLUTION: String insertion holes are provided for binding respective strings to respective scrolls, a worm wheel is provided on a tip of each scroll, and a worm gear is provided on a contact part of the worm wheel for engaging with the worm wheel. The three scrolls on respective bass parts and treble parts are connected by a machine head body, so that the machine head is formed of a member which is lightweight and has durability, and has a knob part extended to length equal to that of a conventional wooden peg, which facilitates tuning.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a machine head used for tuning when playing a guitar.

  It is a machine head for a classic classical guitar, and it can be turned by turning the knob. The center of the knob is within about 2 cm from the gear, and is located close to the guitar head.

  It is known that the body can take a better posture by ergonomically processing a resonance box that is a guitar body (Patent Document 1). Further, there is known a guitar support tool that can be played while holding the heel side high in a natural chair seat posture with the spine extended without widening the legs during guitar performance (Patent Document 2).

  Patent Document 1 has more problems than the structure of a conventional guitar body consisting of a front surface, side surfaces, and back surface, which increases the jointing of wood, resulting in a problem that adversely affects the sound of the guitar itself. It was. In Patent Document 2, since the guitar is fitted with a clamp, the vibration of the guitar body is blocked, which has a problem of adversely affecting the sound.

  Conventional classic machine heads for classical guitars needed to be tuned with arms extended from the guitar neck to the guitar head. Extending the arm to the guitar head while holding the guitar body would result in an unnatural posture, and it was necessary to fix the guitar body between the entire arm and the flank. In this case, the movement to fix the entire arm and flank is an ergonomic movement. For example, in the case of tuning during performance, it is necessary to tune instantly. Due to its unnatural posture, there is a limit to instantaneous tuning. Also, since the picking part of the machine head is close to the guitar head part, tuning cannot be performed with the back straight, so that the performer's ear is close to the sound hole. When tuning, the tuning is performed while detecting the swell generated by the difference in the sound emitted from each string, but the arm does not reach the picking part of the machine head unless the ear is tilted toward the guitar neck. It was difficult to detect the swell caused by the difference.

  The picking part of the conventional machine head was installed about 2 cm from the worm wheel. The reason why the pick part is close to the machine head is that if the metal casting technology at that time is too long, the metal part is easily broken. This is because the casting technology at that time was not as advanced as it was today, and the longer it was, the easier it was to break. Moreover, if it lengthens, a weight will also overlap and it will also have a bad influence on a sound. However, the conventional machine head uses a gear to stabilize the tuning and make tuning easier.

The picking part of the conventional wood peg is about 6 cm away from the guitar head. This knob position seems to be ideal for ergonomics. However, conventional wooden pegs are difficult to adjust because they are fixed by friction between trees, and tuning takes time. If you tune it again, you will go crazy immediately.
The present invention has been made to solve the above problems.

  A string insertion hole is provided so that each string can be connected to the winding axis, a worm wheel is provided at the tip of the winding axis, and a worm gear is provided at the contact portion of the worm wheel so as to engage with the worm wheel. By providing three shafts that are connected together by the machine head body, a lightweight and durable member is used to provide a knob that extends to the length of a conventional wooden peg. Machine head that is easy to string.

  With the present thread spooler, it is no longer necessary to tune the guitar head with its arms extended. As a result, it was possible to hold the guitar body in a natural posture, reach the knob easily, and to tune easily. When tuning during performance, it is necessary to tune instantly, but because of its natural posture and the proximity of the knob, it has become possible to tune instantly. In addition, since the picking part of the machine head is far from the guitar head and close to the body, it is possible to tune with the back straight, so that the performer's ears are further away from the sound hole. I can do it. When tuning, it tunes while sensing the swell produced by the difference in sound emitted from each string, but it can easily sense the swell produced by the difference in sound because the ear can be tuned away from the guitar body, and as a result It became easier to tune.

  The sound coming from the guitar means that the vibration from the guitar strings vibrates to the guitar neck and the body. The easier the vibration is transmitted, the more the vibration is amplified and the so-called “good sound” can be played. In the present invention, the knob portion becomes long and it becomes easy to tune ergonomically, the weight of the peg itself can be reduced by using a lightweight foamed aluminum material and carbon fiber, and the vibration from the guitar string causes the guitar neck and the guitar body As a result, a good sound can be extracted.

  The proposed thread winding tool solves the problem of durability by using a lightweight foamed aluminum material or carbon fiber with a strong grip. The length of the wood peg, which is the machine head of a traditional flamenco guitar (approximately 6 cm) ), It is possible to tune the guitar in its proper posture and improve the tuning efficiency.

  The machine head knob has a peg that looks like a wood peg (Figure 4), which is often found on traditional flamenco guitars. The shape of a long peg, like a wood peg from the guitar head, matches the appearance of a traditional Spanish flamenco peg. As a result, it has become possible to improve the tuning function while maintaining the appearance of traditional Spanish flamenco pegs. By maintaining the appearance of a traditional Spanish flamenco peg, you can get the understanding of traditional lovers and maintain the arabesque style of the Andalusian culture, live and live performances. By using the present invention, the performer can provide a traditional and more serious performance.

N) The string is provided so as to be inserted through the string insertion hole (9) of the winding shaft (3) and penetrate the winding shaft in the diameter direction.
Le) The reel (3) rotates by turning the knob (5) that looks like a wooden peg using a lightweight and durable member.
The machine head for a classic guitar that is easy to tune is structured as described above.

  When using the present invention, the string can be loosened or stretched by turning the knob (5) resembling a wooden peg, and as a result, the sound can be adjusted. A winding shaft (3) is provided, and a worm wheel (2) is connected to the winding shaft (3) to mesh with the worm gear (8). Since the present thread winding tool is like this, the string end is passed through the string insertion hole (9) and the winding shaft (3), and the winding shaft (3) is rotated to wind the guitar string (12). I can take it.

  The machine head peg design can be created with the original ideas of the creators of the traditional Spanish flamenco pegs. In the present invention, the design of the machine head peg is not affected by the function of any design in the structure, and therefore, it is possible to design pegs which are various parts of the machine head with a free idea.
