  • Screwless electronic instrument enclosure
    Patent number: 5013105
    Abstract: The enclosure is intended, among other uses, for a rack-mounted electronic musical instrument characterized in that screws are not required to secure the assembled parts of the enclosure. Top and bottom molded plastic halves (preferably identical) have integral flexible hooks and also projections. The halves have inward turned edges which fit together and mate at the horizontal mid-plane of the enclosure. A generally U-shaped thin, narrow sheet metal core engages the back and both sides of both halves inside the edges of the halves and is formed with holes into which the distal ends of the hooks snap and thus lock the halves and core together. A plastic front panel also has horizontal flexible hooks which snap into holes in the core to close off the front of the enclosure. Outward extending ears on the core may be used to attach the enclosure to a rack.
