Abstract
Two layers of rubber are sandwiched about a layer of metal to provide a surface for practicing drumming. The bottom surface of the bottom layer is roughened to reduce sliding. The device may also be positioned on its side and struck on its opposite side to simulate the striking of cymbals, or placed on the drum surface to dampen undesirable vibrations.
Claims4
A practice percussion device which simulates the feel of a real cymbal or drum when struck, comprising:
- a first smooth rectangular layer of resilient material;
- a second layer of substantially heavier, rigid material slightly smaller in surface area than said first layer and affixed to the center of said first layer so that said first layer extends beyond said second layer on all sides;
- and a third rectangular layer of resilient material approximately equal in surface area to said first layer and affixed to said second layer so that said third layer extends beyond said second layer on all sides, wherein said device maintains a vertical position when balanced on one edge of said first and third layers and struck on the opposite edge with the ordinary force applied to a cymbal, and resists lateral movement when struck on said first layer while resting horizontally on a suitable surface.
