Description

  The present invention relates to a folding guitar in which a neck and a body are connected via a hinge, and more particularly to a folding guitar in which a vibrato unit is provided on a body.

  Conventionally, a guitar in which the neck and the body are folded so that the guitar is useful for transportation and storage, and a guitar in which the neck is removable from the body have been proposed. However, a guitar with a neck detachable from the body is often difficult to handle because the neck to which the strings are connected is bulky, and there are many proposals for a folding guitar in which the neck and the body are folded.

  For example, a folding guitar in which a neck can be folded on the back side of the body is known (see Patent Documents 1 and 2). However, in these folding guitars, the neck that is integrated with the head is not stretched, and the back side of the body is not stretched. In order to fold it into the back side, it may be necessary to provide a complicated expansion / contraction mechanism on the body so that the body can be reduced in the length direction of the neck (see Patent Document 1). In some cases, it is necessary to provide a complicated interlocking slide mechanism on the bridge in order to follow the movement of the string drawn in the neck direction (see Patent Document 2).
