  • Patent number: 4506586
    Abstract: What is disclosed is a quick release drum head restraint for a musical drum. The restraint consists of a pendulum unit and a toggle unit which enable the user to quickly remove and replace a drum head without significantly altering the tuning of the drum head. The pendulum unit includes a tension rod fastened at one end to the rim head and at the other end to a cylindrical pendulum which includes a bushing located at its center. The cylindrical pendulum fits inside the toggle unit and the bushing slides on an inclined plane or ramp within the toggle unit. The toggle units swivels or pivots at a pivot point to engage the cylindrical pendulum and enable the bushing to roll along the ramp. Thus, the drum head can be quickly removed by pivoting the toggle unit to release the pendulum unit and the new drum head can be installed by reinserting the pendulum unit in the toggle unit. Replacement of the drum head does not significantly alter the tuning of the drum head.
