  • Patent number: 10997955
    Abstract: The invention is a guitar hanger rack that comprises a piece of metal (or other rigid material) that is bent and notched at one end and has a curve-shaped cradle at the other bent end. This rack is designed to hold an instrument—such as an electric or acoustic guitar (or other similar type instrument that has a strap button on one end and a neck on the other). The notched end holds the strap button and the other curved cradle end holds the neck of the instrument so that it may be hung from a wall or ceiling. The purpose of the invention is to allow for the display of the instrument at multiple angles and in a manner that will not affect the finish of the instrument.
