  • Patent number: 4723657
    Abstract: Microphones having attached electrical cords are stored for transport in a carrying case by providing separate mutually isolated compartments for the cords to avoid inter-tangling of the cords. The microphones are engaged in spaced parallel relation on the carrying case lid with individual cord-storage compartments disposed to receive respective power cords. The engagement structure and compartments may be a permanent part of the carrying case, or may be an insert adapted to be selectively removable from the case. A novel engagement clip is fabricated from hard resilient plastic material and permits insertion of the microphone handle therein from the side of the clip so as to provide a barrier forwardly of the microphone that prevents the microphone from becoming disengaged as the case is opened and closed.
