Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
145 words
An anchor for a bass drum or other percussion instrument adapted for being repetitively struck by a player, comprising a flexible mat having barrier means at one end, an area adjacent the barrier means to receive the instrument, and an area at the end opposite the barrier means to receive the player, said barrier means including an upward extended barrier strip mounted on the upper surface of said flexible mat and transversely along and superimposed on an end edge thereof, a lower block positioned and extending along and below said barrier strip and mat, said block elevating said mat end edge and said barrier strip and thereby creating a resistive force to said barrier strip resisting tipping thereof by forces applied thereagainst by a said instrument, said mat being compactly foldable about the barrier means for transport, and unfolded on a floor when in use.
Claim 2
Dependent Claim
