ABSTRACT:
A support leg for a bass drum is provided. A circular surface is provided on the base member attached to the drum which has a positioning member thereon. A shaft means projects from the center of the circular surface, one end of which is attached to the base member. Inner and outer block members surround the shaft and have mutually facing surfaces for holding the leg member. The inner block has a mating circular surface which slidably mates with the circular surface of the base member and another positioning member which mates with and engages the positioning member. A means, is provided on other end of the shaft, for releasably engaging the outer block and urging the blocks together. A first spring means between the blocks has a spring pressure for urging the blocks apart. A member connects the blocks for setting and holding a predetermined gap between the blocks. A second spring means is provided between the inner block and base member and has a spring pressure for urging the inner block and base apart. The spring pressure of the second spring means is smaller than the spring pressure of the first spring means. When the outer block is released, the gap between the inner and outer blocks widens to the predetermined gap by the coaction of the first spring means between the inner and outer blocks loosening the leg member therebetween. A gap between the base and inner block is subsequently created by the coaction of the second spring means between the inner block and base to permit rotation of the leg holding member on the base and disengagement of the first and second positioning members.
