Description

  The present invention relates to a folding guitar in which the neck of the guitar is foldable toward the back side of the body, and relates to a folding guitar that is convenient for transportation and storage.

  This type of folding guitar has been proposed for a long time, and there are types that fold the neck to the body side and types that detach the neck from the body. With this type that removes the neck, it is difficult to clean the strings that are connected from the neck to the body, so there are many proposals for a folding type that makes handling of the strings relatively easy.

  For example, in the folding guitar described in Patent Document 1, a guide is attached to the side of the body in order to eliminate the loosening of the string that occurs during folding, and when the neck is folded, the string is wound around this guide. The loosening is eliminated.

On the other hand, the folding guitar described in Patent Document 2 has a string holder attached to the bridge portion of the guitar. This string holder winds the string when using the guitar, and when folding the guitar, the string that was wound from this string holder is fed out and the length of the string is adjusted, so that the string looseness that occurs during folding can be reduced. It is to prevent.
Japanese Patent No. 3887732 Japanese Patent Publication No.59-122

  Each of the folding guitars described in Patent Document 1 and Patent Document 2 can eliminate the slack of the strings that occur when folded, but each configuration that eliminates the slack is a heavy burden on the strings of the guitar. As a result, string management and longevity remained.

  In other words, the folding guitar disclosed in Patent Document 1 employs a configuration in which loose strings are wound together around a guide protruding on one side of the body, so that the strings may be damaged by contact with the guide. . In addition, since each string is locked to the guide in a state different from that at the time of use, if the folded state continues for a long period of time, the string will fold, resulting in a problem that the life of the string is shortened and the tone is impaired. Furthermore, since this guide protrudes from the side of the body during performance, this guide may interfere with performance.

  On the other hand, in the folding guitar of Patent Document 2, in order to eliminate the slack of the strings that occur during folding, a string that is longer than the string at the time of performance is wound around the string holder, and the string that is wound when the guitar is folded To prevent the string from loosening. For this reason, the string wound around the string holder is drawn out every time the guitar is folded and wound every time it is used, so that winding and feeding are repeated with the string tension maintained.

  As a result, the load applied to the strings becomes larger than that of a normal guitar, which may shorten the life of the strings. In addition, in this folding guitar, a direction changing roller linked to the string holder is attached to the bent portion of the neck, and a pinion or the like that links the rotation of the direction changing roller and the string holder is provided. In order to maintain a constant pitch while maintaining a constant tension, high precision is required for each of these devices. In addition, since the entire apparatus becomes large, there is a disadvantage that it is difficult to handle as a musical instrument.

  Accordingly, the present invention has been created to solve the above-described problems, and provides a folding guitar that can be folded without applying a load to the strings of the guitar and that can maintain a constant string tension during use. It is intended.

  A first means of the present invention is a folding guitar in which a neck P of a guitar is connected to a body Q by a swing shaft P1, and the neck P is foldable toward the back side of the body Q. A bridge R for fixing the body R to the body Q is slidably provided on the body Q along the longitudinal direction of the neck P, and a fixing tool 10 for fixing the bridge R to the body Q at a fixed position when using the guitar is attached to the body Q. In addition, when the fastener 10 is released and the neck P is folded to the back side of the body Q, the bridge R moves in the neck P direction together with the string S that is attracted in the neck P direction.

  The fixture 10 of the second means includes a slider 11 slidably mounted on a slide rail Q1 formed on the front side of the body Q in a state of being connected to the bridge R, and one end portion of the slider 11. The operation member 13 includes a crank 12 that is rotatably connected, and an operation member 13 that is rotatably connected to the other end of the crank 12 and that is swingably attached to the body Q. The bridge R is fixed or released at the position of the crank 12 that is moved by the swinging operation.

  The third means is that a string S contact piece 1 is provided at each end of the bent portion of the body Q and the neck P, and when the neck P is folded on the back side of the body Q, the string S is configured to be bent in a substantially arc shape in contact with the frame body 1.

  A fourth means is that a storage portion 2 for storing the neck R folded on the back side of the body Q is formed on the back surface of the body Q, and a lid 3 for covering the storage portion 2 is formed on the back surface of the body Q. Resolved the problem that the heel 4 that is detachably provided and supports the vicinity of the bent portion of the neck P at the position when the guitar is used is located on the neck P side of the lid 3 attached to the back of the body Q when the guitar is used. As a means for

  According to the first aspect of the present invention, when the neck P is folded on the back side of the body Q, the bridge R is moved in the neck P direction by the string S drawn in the neck P direction. It can be folded without applying a load. Moreover, since the string S at the time of folding moves together with the bridge R, the string S is folded while maintaining the interval during use.

  As a result, the possibility of shortening the life of the string is eliminated even if the folded state lasts for a long period of time, such as when the string is wound around the guide at a different interval from that in use. Moreover, since the bridge R in the folded state is released from the fixture 10, it is possible to avoid applying extra tension to the string S. Compared with a conventional folding guitar that repeats winding and feeding while maintaining the string tension. Can extend the life of the strings.

  Since the bridge R is fixed or released at the position of the crank 12 that is moved by the swinging operation of the operation member 13 as in the fixture 10 according to claim 2, the string S and the bridge R Fixing and releasing can be performed very easily. In addition, since the position of the bridge R fixed at the position of the crank 12 is always constant, the tension of the string is also restored to the original state at the same time when the folded state is returned to the use state.

  Since the frame 1 according to claim 3 is configured such that when the neck P is folded on the back side of the body Q, the string S contacts the frame 1 and bends in a substantially arc shape. The folding of the string S during folding is completely eliminated, and deterioration due to deformation of the string S can be prevented.

  According to claim 4, the storage portion 2 that stores the neck R folded on the back side of the body Q is formed on the back surface of the body Q, and the lid 3 that covers the storage portion 2 is formed on the back surface of the body Q. Since it is detachably provided, the lid 3 can protect the folded neck P and string S.

  Further, since a heel 4 that supports the vicinity of the bent portion of the neck P at the position when the guitar is used protrudes on the neck P side of the lid 3 attached to the back surface of the body Q when the guitar is used, even a folding guitar can be used. The same strength as a normal guitar can be maintained.

  As described above, according to the present invention, it is possible to fold the guitar strings without applying a load, without shortening the life of the strings, it is possible to maintain a constant string tension during use, and the like. The effect of this is achieved.

  In the best mode of the present invention, a bridge R for fixing the string S to the body Q is slidably provided on the body Q along the longitudinal direction of the neck P, and the bridge R is fixed to the body Q at a fixed position when the guitar is used. The fixing tool 10 to be mounted is attached to the body Q. When the fastener 10 is released and the neck P is folded to the back side of the body Q, the bridge R is moved in the neck P direction by the string S drawn in the neck P direction. The fixture 10 includes a slider 11 fixed to the bridge R and slidably mounted on a slide rail of the body Q, a crank 12 having one end rotatably connected to the slider 11, An end portion is rotatably connected, and includes an operation member 13 that is swingably attached to the body Q. The bridge R is configured to be fixed or released at the position of the crank 12 that is moved by the swinging operation of the operation member 13. A piece 1 for contacting the string S is provided at the end of the bent portion of the body Q and the neck P. When the neck P is folded on the back side of the body Q, the string S is configured to come into contact with the frame body 1 and bend in an arc shape, thereby achieving the original purpose.

  The guitar of the present invention is a folding guitar in which the neck P of the guitar is connected to the body Q by the swing shaft P120, and the neck P is provided so as to be foldable toward the back side of the body Q (see FIG. 3). The bridge R of the guitar of the present invention has a configuration different from that of a general guitar bridge. That is, in a general guitar, the string S is fixed to the body Q by a bridge. However, the bridge R of the present invention is slidably provided on the body Q, and the string P connected to the bridge R and the neck P together with the string S. Move along the longitudinal direction.

  The illustrated bridge R is attached to a slide rail Q1 formed on the front side of the body Q (see FIG. 1). The slide rail Q1 is formed by notching the surface of the metal body Q to form an opening to which the bridge R can be attached, and utilizing the side edge portion of the opening. However, when the body Q is made of wood or the like, a slide rail Q1 can be provided as a separate member on the surface of the opening or the body Q, and the bridge R can be attached to the slide rail Q1. In the illustrated example, the bridge R is an electric guitar bridge R that allows tuning of the string S by the side of the bridge R. However, the bridge R may be a general bridge R that only fixes the string S to the body Q. good. It is also possible to change the guitar type to a gut guitar or folk guitar type.

  When the guitar of the present invention is used, the fixture 10 fixes the slidable bridge R (see FIG. 5). This fixture 10 fixes the bridge R at a fixed position on the body Q when playing the guitar. When the fixture 10 is released, the bridge R becomes free on the slide rail Q1, so that when the neck P is folded to the back side of the body Q, the bridge R moves together with the string S that is drawn in the direction of the neck P. (See FIG. 6).

  The fixture 10 includes a slider 11, a crank 12, and an operation member 13 (see FIG. 5). That is, the slider 11 is a member directly fixed to the bridge R, and is slidably mounted on the slide rail Q1 of the body Q. The crank 12 is a member whose one end is rotatably connected to the slider 11, and the other end of the crank 12 is rotatably connected to the operation member 13. The operating member 13 is swingably mounted inside the body Q, and is provided so that the crank 12 moves forward and backward of the bridge R by the swinging operation of the operating member 13. The bridge R is fixed at a fixed position or released at the position of the moved crank 12, and becomes free.

That is, the fixed crank 12 is positioned on the neck P side with respect to the bridge R, thereby fixing the bridge R while urging the string S in the extending direction. When the guitar is used, the lid 3 is attached to the back side of the body Q, and the heel 4 supports the base end portion of the neck P (see FIGS. 2 and 8A).

  On the other hand, when folding, as shown in FIG. 6, after removing the lid 3 from the body Q, the operation member 13 is opened to release the crank 12 from the fixed state, and the bridge R becomes free. When the neck P is bent in this state, the bridge R moves in the direction of the neck P together with the string S while the crank 12 rotates. The illustrated operation member 13 is provided with a length that protrudes from the inside of the body Q in the opposite direction of the neck P, thereby facilitating the operation of the operation member 13 (see FIG. 3). Further, a gripping opening 13A is opened at the protruding end of the operation member 13, and the operation member 13 can be used as a handle (see FIG. 1).

  When the neck P is folded to the end, the crank 12 is moved from the initial position to the opposite side as shown in FIG. Then, the lid 3 is attached to the body Q again to protect the folded portion of the neck P (see FIGS. 4 and 8B). 2 to 4 is a locking piece for fixing the position of the operation member 13 in the fixed state and the released state to the body Q.

  A piece 1 for contacting the string S is provided at the end of the bent portion of the body Q and the neck P (see FIGS. 3 and 7). The frame body 1 is configured such that when the neck P is folded on the back side of the body Q, the string S comes into contact with the frame body 1 and bends in an arc shape. The frame body 1 is provided at a height that does not touch the string S when in use, and the surface that contacts the string S when folded is formed in a substantially arc-shaped cross section so that the string S is not bent and wrinkled. Forming.

  On the back side of the body Q, a storage portion 2 for storing the folded neck R is formed (see FIG. 6). And the cover body 3 which covers this accommodating part 2 is provided in the back surface of the body Q so that attachment or detachment is possible (refer FIG. 1). The illustrated lid body 3 is fixed by engaging a locking pin 3A protruding in the inner side of the longitudinal side surface of the lid body 3 with a substantially L-shaped locking groove Q2 formed on the side surface of the body Q. However, the fixing means between the lid 3 and the body Q is not limited to the illustrated example.

  Further, a heel 4 protrudes from the neck P side of the lid 3, and when the lid 3 is attached to the back surface of the body Q when using a guitar, the neck P when the heel 4 is used is at the base end. It supports (see FIG. 2). The illustrated heel 4 has a substantially trapezoidal side surface as a whole and is formed of a substantially box-shaped member (see FIG. 1), and is connected to the end of the lid 3. Can be changed arbitrarily.
