US Patent 7772471 Guitar support

In order to allow a two-sided instrument case to also serve as a stand for guitars and the like, when the case is in its open position, a flat plate having a central notch in one end is adapted to be supported between the open case side so it is closely spaced relative to the hinge which joins the case sides. When the case is moved to the closed position, the plate may either be removed for storage in the case with the instrument, or may be alternatively positioned so that it may be folded into a closed position within the case.
