Abstract
A spring hanging block injection-molded from plastics and coupled to a coupling rod of an end block of a pedal mechanism for base drum to suspend a tensile spring, having a coupling hole with positioning structure configured for fastening to the coupling rod of the end block of the pedal mechanism, a pin hole adapted to hold a rivet, and an end notch through which the tensile spring is inserted and hooked on the rivet.
Claims1
A spring hanging block coupled to a coupling rod of an end block of a pedal mechanism for base drum and adapted to suspend a tensile spring, the spring hanging block comprising a coupling hole transversely disposed near one end thereof and adapted to receive the coupling rod of the end block a protruded stop portion disposed at one side of said coupling hole and adapted to stop the coupling rod of the end block in said coupling hole, two crescent-like flanges disposed at an opposite side of said coupling hole, a gap defined between said crescent-like flanges for the passing of the coupling rod of the end block, a positioning groove defined inside said coupling hole between said protruded stop portion and said crescent-like flanges for the positioning of the coupling rod of the end block, a pin hole transversely disposed near an opposite end thereof and adapted to hold a rivet, and an end notch disposed across said pin hole through which one hooked end of the tensile spring of the pedal mechanism is inserted and hooked on the rivet being installed in said pin hole.
