  • Collapsible guitar having pivotal head
    Patent number: 5383385
    Abstract: A guitar can be collapsed into a compact condition by pivotably attaching the neck of the guitar to the guitar body, such that the neck can be overturned onto (or near) the upper face of the guitar body. The pivotable attachment includes two parallel swingable links that enable an end of the neck to move into or out of a recess in an end surface of the guitar body without disturbing the tension setting of the guitar strings. It is unnecessary to loosen the string tension prior to swinging the neck onto or out of the guitar body recess.
