  • Patent number: 4986158
    Abstract: A modular construction, multiple musical instrument stand may be quickly assembled or disassembled for use in the stage or performing environment. The stand contains a plurality of quickly and easily performed adjustments so that various types and sizes of musical instruments may be supported by the stand, and is expandable so that any desired number of instruments may use the stand by adding additional supports during assembly. Further features may be added, such as trays or other types of containers, in the same manner as the assembly of other components of the stand. The stand may be further expanded by using the telescoping crossmembers to widen the base as necessary for the installation of additional musical instrument supports as desired. In a further embodiment, the upright portion of the stand may be folded horizontally against the base for compact storage.
